Chapter OneIntroduction 1. Introduction of Camera and Charge Coupled Device (CCD) The term camera in genera l is f amiliar for people. T raditional optical camera disp lays the images by the way of film sensitization, and in ve rsus, digital camera stops using film s by applying sensitized components, either CCD (Charge Coupled Device) or CMOS (Com plementary Metal-Oxide Semiconductor). CCD and CMOS are with different structure. Due to structural reason, CMOS images easily appear with noise, and it gets overheat by frequent application. Though CMOS is cheaper, CCD becomes the mainstream due to the requirement of high precision and rapid image processing. CCM Vision sorting machines are equipped with CCD. . CCD is the f ilm of a digital cam era. A digital cam era with 12m ega pixel represents its CCD is consisted with 12m ega pixel. The arrangem ent of CCD is generally rectangular. W ithin same size range, the more the pixels are, the clearer the image appears.

Following items will be considered while purchasing digital camera 1. The chip size: influences CCD display area, usually sizes are 1/2 inch, 1/3 inch, 2/3 inch. The

bigger the chip size is, the finer the images will appear. 2. Resolution: A sensor chip size long by wide, for example: 720 * 480. 3. The images range (Field of view, or FOV): the scope of images taken. 4. shutter speed: time length for image capture; such as 1/500 sec stands for an image to be taken at

1/500 sec.

2

2. Introduction of vision measuring terminology Pixel: Every CCD stands for one pixel in image processing. The color of the image differentiate each other by value of 0 to 255, a value of 0 represents black, the value of 255 represents white, other colors have their own values instead. Corresponding to black-and-white cameras, if the value of 0 ~ 255 represents the different degree of gray, the images are called grayscale images. Binarization is to select a figure between 0 to 255, smaller than the selected figure represents black, larger than this figure are all white, so you can easily convert grayscale image to black and white one. Exposure (shutter) Shutter: the shutter opening time. To shoot a moving object, the shorter the shutter opening time, the clearer the image will become. Longer opening time of shutter will blur the image Contrast : adjust contrast without changing the shutter opening time, and the image can be bright or

dim. However, if the contrast adjustment is too huge, it will cause snowflake-like noise. Brightness: to adjust the brightness of the images. Adjusting range is smaller than Contract, and no

snowflake-like noise occurs. Grayscale level: very CCD value of 0~255 represents one color. This value is so called grayscale level.

3

Focal length: within a certain distance, Camera through the lens makes an object clear image, this distance (Y) is called the focus, the distance of the lens and CCD (y) is the focal length. Depth of field: Through the Lens, the camera can only take one focal length, which means that only

one object can have clear image. If two objects exist in an image, due to different object-locations with different focal length, there will be an object clear and the other object vague, this is the result of the depth of field. The easiest way to increase the depth of field is to adjust the lens aperture to be smaller, the backlight to be brighter. By doing this, the depth of field will be increased, and two objects with different focal length can be clear in the same camera.

Angle of Elevation: The angle above horizontal that a camera must look to see an object that is higher than the camera. When camera focuses the edge of the object, you also see the side of the object. Image size: the size of photos varies from the camera pixel amount. For example, pictures/images are

300,000-pixel, the camera are with 640 X 480 pixel points. Pixel size: represents the actual distance represented by one pixel (pixel) while calculating accuracy

(mm) Actual size: represents the sizes physically measured by measuring tools. Teaching: means the process of editing the measured images taken from a test object. Calibration: the process of calculating the size of measured pixel Baseline: is the based line for measurement AOI: Automated Optical Inspection, referred to as the AOI, high-speed high-precision optical inspection system, which applies vision as the detection Standard, to improve the shortcomings of traditional inspection system of human checking by applying optical instruments. The AOI is

4

applicable for wide ranges of area, such as for R&D of the high-tech industries, the field of manufacturing quality control, as well as national defense and people's livelihood, health care, environmental protection, electricity ... etc

Diffraction: Diffraction refers to light waves passing by the edges of opaque bodies or pores or through slots, causing fringes of light and dark bands.

3. Introduction of lens

The function of the lens is to make the camera shoot objects clearly. Generally speaking, a lens is with a focal length and aperture for possible adjustments. The actual adjustment range of the lens varies from brands to brands with some slight differences. The focal length adjustment is used to make image clear, and aperture adjustment is used to make the image darker or brighter

To choose appropriate lens is based upon the working distance, focal length, and aperture, in order to take clear images. 4Light sources Light source plays a very important role in image acquisition, light hits on the surface of the object and creates reflection or refracted into the eyes, so we can clearly see every objects. The sunlight is the most natural light. Without light, human are incapable to see any objects. Light source will directly affect the accuracy of the measurement. In general, there are 2 types of light source application ways: Front light: front light places between camera and object, which enables the camera clearly capture the object surface. There are many types of front lights for varies of applications, including ring light, coaxial light, bar light, hemispherical light .. etc

5

Backlight: The object is between the camera and light source. With the backlight, the camera can clearly capture the outline of objects The application of backlight is simpler. Only 2 different types: diffusion backlight and parallel backlight

5Accuracy calculation This section is to explain how to apply images to size measurement. For example, a camera with 0.3 mega pixel, image size is 640 X 480 pixels, to shoot a 5mm diameter object. We assume the diameter of object is 200 pixels in the image, then pixel size will be 0.025mm i.e pixel size = actual size pixel = 5mm 200 = 0.025mm

Pixel size can be obtained 0.025mm. The tolerance of camera is 1 pixel, so the measuring accuracy of the object is 0.025mm. With this theory, an object with actual size of 5mm, detected through the detection software will be between 4.975 ~ 5.025mm. This calculation will be completed by the software automatically.

6Control components The control components of CCM superb image screening machine are composed with the Advantech industrial dual-core computer, and PLC controller (Fatek for rotary disc type, Mitsubishi for glass-dial and conveyor type), Delta industrial grade inverter, Japan YASKAWA servo motor control system

19

3.2. Basic functions of the system

3.2.1 Head height, head diameter, washer thickness and washer diameter Image of screw head is captured by the software system, and it pixels are converted into

dimensions of length for sorting through calculation of mathematical formulas, therefore the sorting quality depends on the definition and size of image.

3.2.2 Outer diameter, inner diameter, pitch and thread angle

Image of screw pointed end is captured by the software system, and its pixels are converted into dimensions of length for sorting through calculation of mathematical formulas, as the function in 2.1, the sorting quality depends on the definition and size of the images. Thread angle is determined by measuring the angle formed between the line across a pair of crests and the horizontal line.

3.2.3 Crest shape and broken crest

Make sorting by comparing the images. Compare all the screws with sample for their crest shapes to determine their quality based on the similarity of the images by percent, therefore, besides the definition and size of images, the choice of sample also has an impact on the sorting results.

20

3.2.4 Length There are usually two ways to measure the length, one with and the other without screw head.

Generally, as the inspection point in either ways is positioned in the two images, pay special attention to the definition of the images in setting. Also notice the matter of visual angle, which exists in any non-tapered screw. In the case that length measurement as a critical inspection point, the camera shall be placed at a height as the level of screw end.

3.2.5 Shank diameter and length of threaded section of the shank

The profile of the part to be inspected is captured by camera, and the shank diameter is measured with the function of Shank Width, while the length of threaded section of shank is measured with the function of Bottom Length for sorting. In applying the function of Bottom Length, make sure there is explicit plane at the place to be defined for the sorting program to make determination.

3.2.6 Inspection of in-hole thread One way to inspect if there is any thread in a hole is to apply a pin as adequate, those with

threads are considered as good parts if the pin cannot be inserted into the hole with its entire length (and can if there is no thread in the hole); another way to make such inspection is to carry out a test of optical fiber on the fixed base of the lighting source for camera 3, which can be done directly with the programmable controller and sensor without going through the software system.

21

3.2.7 Pin depth inspection Apply a presser mechanism to insert the pin as adequate into the hole of screw head to make the

test of broken pin in simulation of artificial measurement by depth gauge. For good parts, the pin will be inserted into the hole with its entire length, otherwise, it can not be inserted into the hole with its all length.

3.2.8 Application of head socket

In association of the adequate socket and presser mechanism, the function of Head Height and Head Shape can be used to sort out the screws with head dislocation, head deformation, steel button deformation and with or without steel button.

3.2.9 Quality of thread (If there is any sloped thread or lack of thread)

Capture the image on the part of thread to be sorted, compare the images and determine the thread quality based on the similarity of images by percent. The Two Threads Mode shall be selected in setting, further more, it is favorable that the sample has more intact and fuller. The sorting can also be made in association with the thread angle.

22

3.2.10 Trailed, twisted and slotted ends Use presser mechanism to rotate the screw 180 around its own axis in front of the camera,

capture the motion pictures during the rotation of screw, then observe the physical shape and size of screw from several angles to find out the difference between the good parts and the bad parts for sorting. This function can be used to inspect the defects such as trailed, twisted and slotted ends.

3.2.11 Ineffective thread length (Unthreaded length or not threaded sufficiently)

Support the screw from its end so that the first thread under the head is not covered by index plate, then check if there is any deficiency of outer diameter or lower position in the first thread by defining the horizontal dimensions in this area.

3.2.12 Head-crack Use the drawing unit in the program function library to process the images captured from the

outer edge of the head to obtain the different pictures between good parts and bad parts, then convert the pixels of the obtained images into the dimension of area for sorting.

23

3.2.13 Displacement and eccentricity of head hole The sorting program calculates as defined the central point of outer edge of head and the central

point of head hole, then calculate the distance between the two central points, the obtained distance is the size of displacement; a product is determined as bad part when the size of displacement is larger than or equal to the specified tolerance.

3.2.14 Head diameter, roundness

Use the central point of the outer edge of head as the circle center to split the head image by equal angle degree, and measure the length of 12 diameters of the head to determine the deformation of head. If the difference between the longest diameter and the shortest diameter is larger than the specified tolerance of head roundness, the product is determined as defective. In defining the inspection, a significant difference is that the longest diameter of sample head shall be entered into the program to have a precise measurement of head diameter.

24

3.3Mechanism Setting

As this system captures images by high resolution camera for precise measurement, user should do routine cleaning in the operating area prior to setting for new object to be inspected to avoid unanticipated error. The cleaning areas involve the route that the object to be inspected may go through (storage system, aligning system, inspection platform, reject system), imaging system (camera, lenses), and even the surrounding areas. Set up step by step as follow after cleaning:

3.6Hopper operation 3-6-1. If the feeder has plenty of parts inside, the end of swing pole will be taken away from vertical

position and incline an angle. In this situation, the light will be off. If less parts are inside the feeder, the swing pole will swing back naturally and will be more likely a

vertical orientation. In this situation, the light will be on and send a signal to hopper to feed parts.

symmetric adjustment on both sides is required.

Step 1 Firstly remove the four screws on both sides to take off the lid

Step 2 Loosen the column block screws to adjust the position, the vibration amplitude is divided into three scales

1.low amplitude scale 2. medium scale 3. big scale

3-6-3. Full feeding time on feeding controller (PS-888): stands for the time length of power for hopper motor .The longer the time length is set, the more parts will be fed into feeder. Material Empty time: stands for the sensing time length of the sensor on the swing pole. The longer the sensing time is set, the longer feeding interval will be

Full feeding time: the bigger the figure is, the longer the Delay time will be. Material empty time: the bigger the figure is, the longer the Delay time will be.

If the time is set too long, itll cause screws jammed in feed-in track. If the time is set too short, it might cause constantly machine stop, due to no-feed-in.

Empty: the bigger the figure is, the longer it delays before start to feed. If the time is set too long, it might cause constantly machine stop, due to no-feed-in.

3-7-3 Tips on adjusting vibratory feeder and Hopper 1. Control the quantity of screws in feeder to prevent any clashing damage of screws. The quantity

of screws in the feeder can be adjusted by the swing pole and the feeding controller; 2. If the quantity of screws in feeder is less, the swing pole will be more like in vertical oriented; if

the quantity of screws in the feeder is full, the swing pole will be more inclined. 3. The longer the full feeding time on feeding controller of hopper, the longer the feeding time.

The longer the material empty time on feeding controller of hopper, the longer the interval of no-feeding time.

4. The gap of feeding track on the vibratory feeder shall be adjusted gradually from the vertical height to the horizontal width, the gap shall be from narrow to wide to prevent jam of longer screws; the gap shall not be wider than the head.

5. The smooth movement of screws and the maximum flow may be facilitated by regulating the flow with the flow control plate, it is recommended not to increase the flow only by regulating the speed (or even to a too high speed) on the feeding controller, which results in screws jittering in place rather than moving forward.

This switch on: Feeder stops automatically when no parts in the feeder.

3-8. Feed-in track Feed-in track is to guide screws to the bore holes of rotary disc. While adjusting, make sure the feed-in track align with the bore holes, if not, adjust the track to left or right, and make sure the screws can enter the bore holes smoothly, if not, adjust the track forward or backward, or adjust its height or angle of elevation. The track end can be a bit higher (do not lower) than the Rotary disc to let the screws move smoothly to the bore holes of rotary disc. However, too high will cause the jam of screws; the gap between the track and rotary disc should be as small as possible only if they dont get into contact. To finish the adjustment, adjust the fixing block and feeding-in auxiliary board to a position as proper before fastening the screws.

Step 1: Loosen the Feeding track height board for track width adjustment

Step 2: Loosen the large knobs and nuts to adjust the track width.

Restore the Feeding track height board and loosely fasten it to an extent that the gap height can be adjusted easily with the height adjusting screw. In adjusting the height, make sure the screws can go smoothly through the track and fall down on rotary disc. It is recommended to keep the inlet higher than the outlet, and finally fasten the small star knob and nut (As shown in the figure below) (Generally, the upper track is wider than the lower track).

3.9 Guide of CCD Adjustment The Base of CCD allows adjusting vertically and horizontally. CCD position is decided by the size of images.

Tips: How to adjust the CCD Image: Adjust the aperture roughly to get a blur image. Then adjust the focus to get a clear and sharp image. If the image is not satisfying, we can add or reduce the extension rings between the lens and camera. As well, adjust the CCD position to get a bigger and clearer image. Please note that an aperture with a big value will cause over exposure and distortion, which is called diffraction phenomenon. We can also adjust the CCD as well as the light-house control box, to get the best images. Clear and sharp images are beneficial to the stability of sorting work; while large images are beneficial to reduce error.

Step 4: place another disc on to the machine

Step 5: press Jog to get the right positioning( press 3~5 times)

Tips: Selecting suitable rotary disc. Standard rotary disc will have 24 bore holes for hanging screws. If bore hole is much larger than the shank width, the screw will have big swing and displacement during rotation which might influence the accuracy of inspection. If bore hole is too close to the shank width, screw might have difficulty to get in the hole or have difficulty to discharge it. Optimal rotary disc should have bore holes that is slight larger than the shank width and will not interference the discharge.

Step 6: Observe the adjusted positioning of feed-in track as well as rotary disc

Improper positioning: offset in the wrong place.

Adjust the Plunger Stroke The plunger stroke can be long stroke or normal stroke. The height of stroke is controlled by a cam in the motor housing. On the cam there are two screw holes, for center hole, its for normal stroke; for the hole away from the shaft center, its for long stroke. Long stroke is for higher head screw or to combine a rotary recess-pin to inspect the recess depth by mechanical action. However normal stroke has higher speed. User can select according to the sorted items.

3.13. Position sensor adjustment Correct Correct Wrong

The positioning sensor is a photo interrupter sensor (As shown in the Figure above) Light-off is a signal to capture image; while light-on is a signal to stop capturing image. All movement of machine is guided by the trigger of sensor, so it is called a position sensor. All stroke mechanisms should associate with position sensor. Standard machine equips with a 24-index, while rotate the hand wheel a circle, itll be a complete inspection cycle..

3.14 Adjust reject mechanism PS 1500

There are two parts in the reject mechanism, one for reject of good parts and the other for bad parts (As shown in the figure below).

Blow pipe and discharge cylinder (For PS only) While reject parts comes, cylinder will be activated and withdrawed, in the meantime, the blow pipe will blow rejected screws into the chute of NG parts;

Reject picker (For PSL only) Bigger screws (Length: 20.0 ~ 115.0 mm, outer diameter 6.0 ~ 16.0 mm) shall be sorted by PSL series. However, rejected bigger screws may not be able to discharge to NG chutes by using a air-blower mechanism. Thus all the models of PSL utilize Cylinder picker to discharge NG parts into NG chute. (As shown in the figure below). While NG parts comes, cylinder will be activated and withdrawing to push parts into the chute.

3.15 Adjust Laser Check Point 3-15-1 If defective NG parts is not discharged, all warning lights flash. This is a foolproof mechanism to prevent NG parts sorted to OK parts, in case of any error occurs. User must check its normal per every inspection. When locating the rotary disc, the red spot of laser check point shall be projected at the hole of index plate, otherwise, please make adjustment. In case the screws are black or the other colors that do not reflect laser well, or are contaminated by oil dirt or become rusty on the surface, that will result in poor reflection of laser and cause incorrect determination or stop operation. To solve this problem, raise the intensity of sensor to improve the sensitivity.

3.22 Recess Depth Inspection and Rotary Socket The setting of hardware needs the inspection unit of rotating head (As shown in the figure below), the

proper punch socket and proper punch (It is recommended that user uses the used formed punch still compliant).

57

To inspect recess depth effectively, user shall be cautious here that the recess-check mechanism will be lowered and shall touch the screws in inspection, while the front end of punch shall enter the recess pin-hole in the screw head (As shown in the figure below).

Therefore, in adjusting the hardware mechanism in this part, user shall make sure that the central point of punch shall be right against the central point of bore hole of rotary disc as possible (May also be just the central point of screw head) when the recess-check mechanism is lowered to touch the screw. (As shown in the figure below)

58

Here is the general faulty setting, and user shall pay special attention to them. Much the punch is positioned inside the index plate Much the punch is positioned to the right side of screw punch hole of index plate

59

Generally, it is recommended to change the inspection stroke to long stroke when using recess-check mechanism. In inspecting the broken-pin, plugged-hole, recess-depth or other similarities, the recess-check mechanism shall not be lowered to a height that is too low, i.e. when the mechanism is lowered to the lowest point of stroke, that spring will not over-compress and it can rotate smoothly down into the punch hole (As shown in the figure below).

The setting for software has no difference from general setting, in which the recess depth is calculated on the basis of the distance between the central point of tune-up area for head position and the lower edge of head compressor, as a result, the tune-up of head position is relatively important.

Spring compressing

Refer to this notch for the rotating

60

There are many similar applications, and only the application of socket is described here. For some screws used for outer wall construction (As shown in the figure below), their heads are shielded with stainless steel cap to prevent the rusting of screws.

However, as it is hard to control the occurrence of bad parts in the process of cap fabricating (As shown in the figure below), there may be significant impact on the construction and screw life.

With the above setting, if the punch is removed and its socket is replaced by head socket, then the bad parts can be sorted out by defining the head height function as above.

3.23 Inspection of wheel crack Corn Mirror is developed by CCM (Ref. No.: LS 1501). This module is used to inspect the crack in

the round periphery of screw head, which is completely invisible when looking down from above by standard lens.

Setting of wheel crack set Select Corn Mirror set

The principle to select Corn Mirror (Ref. No. LS-1502) is generally the same as the Rotary Disc. As required for imaging, the height of imaging end in Corn Mirror (As shown in the figure below) may be attached on Rotary Disc, i.e. the inspected screw head may be completely covered inside the lens.

Therefore, the diameter of Corn Mirror opening at the imaging end (We defined this diameter as the specification of Corn Mirror) shall be a bit larger (but not too larger) than the outer diameter of screw head, an opening diameter much larger than the outer diameter of screw head may affect the authenticity. Specification of Corn Mirror is proportional to the outer diameter of screw head captured image and consequently affect the accuracy of inspection. It is recommended that the dimension of Corn Mirror is proportional to the outer edge of screw head by 1:1.2, but the Corn Mirror of larger dimension may be selected to prevent the possible damage on it if there is significant variation of screw head diameter.

62

Setting of Corn Mirror Generally, the height of Corn Mirror set is set at a lower height to meet the requirement of imaging, the gap between imaging end and index plate is usually smaller than 1.0mm, but the height of Corn Mirror is adjustable depending on the shape of screw head and crack.

The lens set can be set as the light source of camera 3 in two positions, i.e. the inspection unit and the light source positioning lever of camera 3 (As shown in the figure below). Usually, it is set on the inspection unit, where the height of the entire Corn Mirror set is adjusted with the height regulating screw of Corn Mirror.

Chapter Four : HMI Interface Operation Man-machine interface(HMI) has been integrated into this sorting system in order to enhance the control efficiency and the convenience of machine operation and design. In the HMI, thousands of virtual buttons can be programmed to replace the physical wiring buttons. On the HMI, all machine running status can be displayed by text, and graphics. No matter how complex the machine might be, control panel can performing all status displaying, and greatly reduce costs for development and assembly.

HMI operation interface I. Enter the page : after the power is switched on, this page automatically shows,

meaning it is ready for operation.

II. Main page

Press Enter and it comes to the main page of the system. The top gray column displays the condition of the machine.

67

System can run under Manual and Auto. Manual is applied for machine setting as well as trouble shooting, and Auto is applied after setting or after problems solved. By touching the panel, you can switch the 2 functions easily.

Manual: The following functions can only run by Manual mode.

rotary disc continuously runs clockwise. Rotary disc moves by single-cell movement, once one press makes the disc rotate one grip. Execute parts discharging. Start or stop the Cylinder function on the Feeding track Turn on or off of the power of the feeder System records qty during inspection, and by pressing this bottom, the qty can be reset. optional functions, switch on/off the vacuum for dust suction

This window is to show the rpm and pieces per min.

III. Parameter setting

This page offers operator the function to do the qty setting. On the HMI, it will show total qty reaches as set qty. Low speed setting enables machine to run at lower speed before qty is reaching, to ensure the accuracy of qty counting. (If operator found the machine run only at a very low speed and unable to speed it up, maybe the set quantity is set too low.)

Continuous NG setting is to remind the operator that NG parts are defected continuously, and that might be caused by error setting, or due to exceptionally too many defective parts. This function can be applied while its needed.

69

IV. Error resume

This function is to record all error messages happened in the machine. Operator can learn about all errors that were happened to the machine and gather relative information.

V. Validity is due.

This info shows when the validity is due. Please contact the supplier for further processing.

the pre-set CCD position. Click image, start to adjust lens and light source to get optimal image, which means the most clear image within the inspection area.. Close the image after all adjustment is done. Click teach to enter the key steps:

There are 6 sorts of main sorting items.

Sort 1: Measuring setup This is to inspect distance between any 2 parallel lines and 2 horizontal lines, the

angle of oblique straight lines. In one screen, 30 different sizes can be inspected by side-view CCD.

Sort 2: Head inspection

All images taken vertically from top to bottom or from bottom to top are being taught By this inspection item.

Sort 3: Inner thread

To inspect the presence of inner thread. This item is applied by 45 degree CCDs, from the upper or from the lower level. In the case of plated nuts, which are clean and dry, the pitch distance of inner thread might be inspected, sorting of big or

73

fine threads might also be possible.. Sort 4: Outer Thread This is the full sorting function of screw sorting, incl. Head height, head width, under

head length, thread major diameter, thread minor diameter, pitch distance, thread quality, bevel angel, head shape, tail shape. These are inspected by side-view CCD.

Sort 5: 360 thread This is an advanced function of inner thread. The 360 thread image is taken by

special lens. It can inspect thread damage or thread presence. Sort 6: Octagonal lens This is an optional function for twisted hex of nuts.

I. Side-View inspection: Multi Height, Multi width, Angle

Enter the teaching screen,

A. Choose the sorting items. B. Open Item page

Click to enter the measuring setup. Only 6 steps will be taken. Measurem ent is done by gray scale image..

74

Step 1: Selecting the sorting item Horizontal: from left to right. Click the horizontal, and green column appears. Place the green column on the inspection area, and 2 red lines shows the measuring distance.

Vertical : from top to bottom Click vertical and see one green column. Place the green column on the inspection area and see 2 red lines. Distance between 2 red lines is the distance to measure. Angle: An oblique straight line seen as baseline. By the way of contract % inspecting the angle, the sorting accuracy is about +/- 1 degree Click on the angle, a green column will appear. Place the column on the oblique straight line to be inspected. One line will show, and after teaching, this line will catch the oblique straight line automatically.

2R: considering the realistic demand, 2 different measuring positions can be selected by 2different columns.

75

Horizontal neck width, vertical head height: this is to inspect smaller area.

Positioning: as images may vary slightly, positioning line is to make contrast of teaching area

and distance between test objects, and move the teaching column following object. In other words, teaching area may move following the test object to get more accurate inspection function.

Position X for horizontal movement Position Y for vertical movement

Baseline: special features, no baseline for objects shot from top-down, then select part of the object to measure the distance between the horizontal and vertical

76

Binary: when images are shot too bright or too dark, binary can change the effect of the image. Measurem ent sensitivity: come to black and white boundaries, divided into six levels of sensitivity, very high, high, high, low, low, and very low. The higher the more sensitive, and when black and white are vague, it requires high sensitivity.

Save fail image: fail images can be saved on to C: \ path Failimages while inspection running.

If more sorting items are needed, click Add to add more items. Currently, there are 8 functions available.

Step 2: After completion of the sorting items settings, press the teach bottom, the software will execute all set sorting items. The sorting result is shown in pixels.

77

Step 3: Key in the maxi and min value according to the print, and the actual value by physically measuring the sizes.

Step 4: Click calibrate and software will calculate the pixel size.

Step 5: Click Inspection, to check all setting are done.

78

Step 6: Save all settings.

II. Head inspection

S teps are as above mentioned. On the main page, enter teaching and select head sorting items, screen will enter head inspection page. 6 steps to complete the teaching.

79

Step 1: A. Select head setting. There are 4 head shapes:

round, hexagonal, quadrilateral, slotted. Here we take round shape as example, so we choose round, the outer diameter of the head on the image is black, so we chose Dark, If the outside diameter is displayed in White, then choose Bright.

B. Select the sorting items, depending upon the requirement to select the items, such as head diameter, electroplating, roundness, pinhole concentric, broken pins, recess. While selecting sorting items, Advanced Settings will show as below:

Step 2: Teaching After finishing sorting items selection, start to do teaching

Software wizard will lead the operator step by step to follow instructions to take actions. Click Next, if theres no need to do any setting. While setting head detecting area, there are 2 concentric circles: Big one circles the outer diameter, and small one circles inside of outer diameter.

80

While doing binary, adjust the blue area to be fully round. This step will influence the roundness checking.

Different plating shows different effect under CCD. Computer will calculate the average value from the selected area based upon the detected gray scale value.

Roundness checking will find the central point first, and get the smallest radius and biggest radius. Roundness is the difference of the 2 radius. During sorting, Red= oversize, Blue=undersize, Yellow=error, Green=OK

81

Pinhole concentricity setting requires a closed curve to find the center of the pinhole and the center offset. The checking result is shown in pixels.

Step 3: enter the Actual values

Step 4: convert the pixels value. Click Calibrate to get pixel size.

82

Step 5: Click to test if teaching steps are done correctly.

Step 6: Save teaching setting

83

III. Side View: Outer thread The outer thread is the easiest sorting item to set up. It applies backlight, and the operator needs to avoid diffraction phenomenon occurs on images. For rotary discs type machines, it requires 2 CCDs to take images, one from the head area, and the other from the thread area, as shown below:

After teaching of head area is done, continue to do the teaching of tail area. Steps are as above mentioned: 6 steps to complete teaching.

84

Step 1: Select teaching items Select teaching items from the listed sorting items. From the image shown, this image can only be measured its head height, head width, so only select these 2 items.

In the Main setting, no thread means on the shaft, there is no thread to be detected. However, Head area still requires as this is going to be a baseline for some calculation based on parameters set, such as the screw datum is skewed, then the head must be applied as the baseline to increase the inspecting accuracy. As long as threads are with 2 different sizes, this function is required. Main Setting: Measuring sensitivity: If the difference of brightness between background and object is low, select higher sensitivity. In the contrary, if difference is high, select low sensitivity. There are six levels of sensitivity, very high, high, high, low, low, and very low. Note: If backlight is too light, it would cause diffraction and cause trouble for computers judgment. Adjust the brightness of light as a solution. With Head: If the image of thread has head. No Thread: No thread means on the shaft, there is no thread to be detected. Bright: If the inspecting area is brighter than background, turn on this function. Screw Alignment: specify the screw is orientated in vertical or horizontal. Used Head Bottom as Reference Line: If screw is inclined, set head bottom as reference line might increase the inspection accuracy. Auto Teach: For standard 60 thread, turn on auto teach function. High Low Thread: If thread has 2 different sizes, turn on this function. Save Fail Images: Fail Images will be saved automatically, while machine is running. This would increase the loading of computer. The limit of image can be adjusted from the system command. Save Success Images: Save success images, while machine is running. This would increase the loading of computer. The limit of image can be adjusted from the system command.

85

Step 2: Teaching. After selecting teaching area, start to do the

teaching steps. Adjust binary to make the object clearly seen, then the next setting. Select inspecting head area, then click next to complete the teaching. When teaching is finished, it displays the qty of pixels .

Step 3: Enter the values of the pixels.

Step 4: Calibration. Convert the pixels into actual sizes.

86

Step 5: Click inspect to make sure teaching is done successfully.

Step 6: Save the teaching file.

87

After Head teaching is done, continue the tail teaching. All steps are the same.

Step 1: Select sorting items

From the image taken as example, total length, major diameter, tail shape, and also thread presence.

Step 2: teaching. After sorting items are selected, start to teach.

Adjust binary to get clear image. Click next.

88

Teach Thread Region: The program will guide user to place column on suitable area. If there has no thread, itll measure the major diameter. If there are threads, itll measure major diameter, minor diameter, pitch, thread angleetc. While teach the thread area, at least 3 good threads will be required, but 1st thread and the last thread should be avoided.

Tail area teaching to inspect the total length as well as tail shape. Continue the next, teaching finishes. The tails shape will be recorded for contrast.

Step 3: Enter the values

89

Step 4: Click Calibrate. Convert pixels into sizes.

Step 5: Click Inspect. Make sure all steps are correct.

Step 6: Save, this is the most important step.

90

Teaching steps are completed. Click Exit to return to the main page. Click Static Inspection to check if there is any problem. By Static Inspection, software can take 50 images per min.

If theres no setting error, click Run , the machine will start to sort automatically.

IV. Bending (Optional Function) Bending checking is an optional function which required 2 additional CCDs to confirm the presence of bending. The 2 off CCDs cant carry out other function simultaneously, and mainly aim at bending checking. The maximum limit of PS series is 4 off CCDs, whereas that of PSL is 6 off CCDs. Due to this reason, bending checking is recommended to used on PSL series for larger space to install the additional CCDs.

91

Illustration of bending checking. 2 Lens as a foolproof, in case the screw rotates to a degree and cheat the CCD no bending.

Using a measuring device to check the bending, the bending degree will be double of the result of CCM measured.

The CCD setting of bending checking will be set by CCM before ex-factory, however, if this function is purchased after-sales, then user can change CCD setting at users premise. Following is the procedure of CCD setting.

Ejection failure at Rejection chute, Retest chute, o r Restart area (Applicable for PSL-1500 series)

B. Errors or Abnormity The location of check-point sensor might be too low, causing ejection failure. The problem of ejection cylinder, might due to lack of air, or cylinder is down. The solenoid valve is contaminated Reed switch is damaged When the machine is stuck during the operation, operator can check the positions mentioned above and remove the problem.

Question 3: The yellow light is on: feeding shortage Troubleshooting: feeding shortage; the output speed of vibrating f eeder is slower than the sorting

speed, the reasons may be as follow: The vibrating feeder is stuck due to the cr ossed screws, defor med screws, or foreign

objects. Or the setting of loading period is too long. The feeding track is stuck The speed o f vibrating feeder becomes slow, which might be caused by changed m ain

voltage or overfed hopper The setting of empty time for feeder is too long

Question 4: CCD error or computer crash when the software executes an image capturing action Troubleshooting: CCD1 error , the problem might be the cable of camera 1 or cam era 2 or the

cable of I/O card. One of them might connect improperly or is disconnected. CCD3 error, camera 3 is connected improperly or disconnected.

Question 5: Computer cannot be started up Troubleshooting: the RAM or graphic card can not be found in the computers BIOS system. Most

of the time, it is due to bad connection caused by dust on the slot which impair the connection.

For industrial com puter, please contact CCM when such problem happens. We will contact the PC su pplier to deal with it if it s on warranty period. Any disassembling of the computer will lead to the invalidity of warranty.

For general computer, users only need to ask computer personnel to open the case and carefully rem ove the RAM, graphic card, image capture cards or I/O card, and after cleaning dust on all cards a nd the mother board by air gun. Then re-assemble them on t he computer. When cleaning with air gun, keep an adequate distance to prevent dam aging of the precision com ponents in the computer.

Question 6: Error message or screen in executing process, when software system is started

105

Troubleshooting: the RAM or graphic card can not be found in the computers BIOS system. Most of the time, it is due to the bad connection caused by dust that blocks the PCI slot and impairs its connection.

For general computer, users only need to ask computer personnel to open the case

and remove the RAM, graphic card, im age capture card or I/O c ard, and after cleaning all these parts and the m ain board by blowing the dust, reinstall them back to the com puter. When clean ing with air blow gun, k eep an adequate distance from the com puter to p revent the over air pressure from damaging the precision components in the computer. For industrial com puter, please contact with Chin Chang when such problem happens, and we will contact the m anufacturer who prov ides warranty to deal with it. Any disassembling of the computer will lead to the invalidity of warranty.

Question 7: Machine emits strange noises while running Troubleshooting: Following reasons might cause such noises:

Lack of lubrication on the rod bearings in motor chamber, for maintenance please refer to Chapter 6 - 4.Motor chamber.

Either the index plate is too low or the acry l plate for source light scattering of camera 1 is too high, which results in noise from their mutual friction. User may take adjustment as adequate.

Either the index plate is too high or the acryl plate for source light scattering of camera 2 is too low, which results in noise from their mutual friction. Users may make adjustment as adequate.

Either the index plate is too low or the end of feeing tr ack is too high, w hich result in noise from their mutual frication. User may make adjustment as adequate

Question 8: Machine stops running suddenly, no warning light is on, or yellow light flashes once. Troubleshooting: this fault usually occurs when the pressure is insufficient. It may be caused by the

over air blow of alignment on the vibrator y feeder or the over air blow on the feeding track, or there is leakage of pipeline. U ser may switch off the vibratory feeder and feeding track in turn to see if any improvement is made, then check if there is any leakage of pipeline that causes the insufficient air pressure.

Question 9: Incorrect count, qty insufficient, even a lot less Troubleshooting: the counting sensor beside the good parts exit chute may be contaminated by oil,

dirt or dust, which results bad reflection. To prevent this fault, clean this area prior to setting. As cleaning this area, users must remove the entire base of optical fiber and align its head with the outlet of the beams using air blower to blow off the dirt on the optical fiber head before cleaning it with paper tissue; adjust the optical fiber head to a position (general as 0.5~4.0mm) as proper (m ay vary with th e object to be inspected) before restoring the seat of optical fiber.

Question 10: Light source flashes twice for one test object Troubleshooting: Incorrect setting on inspection point. The interceptor optical sensor is intercepted

twice for a same inspected object. Rotate forwards the hand wheel slowly to find the cause of the fault, and adjust the sensor or interceptor to a height as adequate.

Question 11: The red light flashes for no reason, in spection result is not correct, or light source flashes at an instable frequency (Light source flashes only one for several inspected objects) Troubleshooting: The interception optical sensor b ecomes less sensitive in reflection due to the

contamination or is defined incorrectly , or there may be short circuit of signal in programmable controller. When this fault occurs, check the interceptio n optical sensor at th e inspection point first, check if the height of sensor related to the interceptor is adequate, then clean th e control cham ber with air blow gun and eliminate the short circuit if any.

Question 12: Rejection cylinder cannot be restored when air pre ssure is released after a re jection failure Troubleshooting: This problem often happens when the cleaning work is not done properly during

machine setup. Nor mally, rejection error signal occurs, th en cylinder will b e sucked, in the end, m achine can not be started, these are caused due to wrong setting on the solenoid valves. To fix the wrong setting needs to restore th e solenoid valve first. User presses the manual button of the solenoid valve in motor chamber with unreleased air pressure, wie shown in the photo below . Press both the up and down buttons to restore the positioning of solenoid valve.

Then clean the m achine properly, especially to remove the oil dirt, ink and the lens of laser sensor for abnorm al rejection under the inspecti on point of abnor mal reject, now the m achine should be able to run properly.

Question 13: How could we adjust to get the image clear on screen?

1. Camera adjustment (front and back , up and down ) and lens adjustment (focus and aperture). 2. Light source up and down adjustment. 3. Gain and exposure option at computer. 4. Light source brightness option and upper/lower lighting turns on/off.

Question 14: W hy I cant check head dimension from side view.

The diameter of plunger should be lar ger than the head diameter, otherwise sof tware will n ot be able to f ind the datum and cause error. User can make plungers by themselves. The ratio of plunger OD and head OD should be appropriate. For better result, the parts are suggested to posit center of the plunger.
