Abstract
Description
Technical Field
[0001] This invention belongs to the field of testing equipment technology, specifically relating to a surface defect testing device for a TRAY disk. Background Technology
[0002] A tray specifically refers to an "IC tray" or "material tray," typically a rectangular plastic tray with grooves or grids precisely designed according to the shape and size of electronic components (such as chips, integrated circuits, LEDs, connectors, etc.). Its main function is to prevent damage to delicate electronic components during transportation and handling from static electricity, vibration, and pressure. Regarding the quality of the tray, firstly, the flatness of the surface supporting the parts must be guaranteed to ensure positioning accuracy; secondly, the upper and lower surfaces of the tray must be free of damage, otherwise stacking will be difficult. Therefore, the flatness of the supporting surface and the appearance defects of the upper and lower surfaces of the tray must be inspected before use.
[0003] Currently, most tray inspection methods employ perspective inspection. This involves placing the tray on a conveyor belt, which moves it below a perspective inspection device. The device scans and photographs the tray, transmitting the images to a dedicated image processing system. Based on pixel distribution, brightness, color, and other information, the images are converted into digital signals. The image system then performs various calculations on these signals to extract target features and determine if the tray has defects. However, existing defect inspection equipment lacks a mechanism for centering the tray from both sides when transporting it via conveyor belt. This leads to positional shifts when the tray reaches the perspective inspection device, preventing a complete image capture and impacting inspection efficiency.
[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a device for detecting surface defects on a TRAY disk.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention
[0006] The purpose of this invention is to provide a surface defect detection device for a tray, which can solve the problem that existing tray defect detection devices lack a center guiding mechanism for the tray, resulting in positional deviation during tray transportation and thus affecting the detection efficiency.
[0007] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution:
[0008] A TRAY disk surface defect detection device includes: an operating frame, a conveying assembly, a viewing angle scanning assembly, a center guiding mechanism, and a control mechanism.
[0009] A C-shaped support frame is mounted on the operating frame. The conveying assembly is mounted on the operating frame and is used to convey the tray. The viewing angle scanning assembly is mounted on the C-shaped support frame and is used to perform viewing angle scanning on the tray.
[0010] The central guide mechanism is mounted on the inner wall of the operating frame. The central guide mechanism includes: a pair of guide partitions, multiple pairs of rotating arms, and a pair of measuring components. Each pair of guide partitions is connected in parallel to the inner wall of the operating frame via multiple pairs of rotating arms, and multiple tensioning components are installed between each pair of guide partitions and the inner wall of the operating frame. Each pair of measuring components is mounted on one pair of guide partitions.
[0011] The control mechanism is installed at one end of the pair of guide partitions. The control mechanism includes a pair of control rods, a crossbar, and a pair of connectors. The pair of control rods slide on one end of the pair of guide partitions, and each is equipped with a telescopic control assembly between itself and the guide partition. The crossbar is fixed to one end of the operating frame. The pair of connectors are fixed to the ends of the pair of control rods that are close to each other and slide on the crossbar. Each pair of connectors is equipped with a fixing assembly between itself and the crossbar.
[0012] In one embodiment of the present invention, the conveying assembly includes: a pair of drive shafts, a conveyor belt, and a plurality of support rollers. The pair of drive shafts are respectively mounted at both ends of the operating frame, and each drive shaft has a pair of drive wheels fixed thereon. A pair of drive belts are fixed to the inner wall of the conveyor belt, and the pair of drive belts rotate on the two pairs of drive wheels respectively. The drive wheels and drive belts are respectively provided with matching grooves and teeth. The plurality of support rollers are mounted between the pair of drive shafts and fit against the inner top wall of the conveyor belt.
[0013] During use, one of the drive shafts needs to be connected to an external drive motor. The drive shaft drives the conveyor belt to rotate through a pair of drive wheels on it and a pair of drive belts on the inner side wall of the conveyor belt. In addition, by setting corresponding grooves and teeth on the drive wheels and drive belts respectively, slippage between the drive wheels and drive belts is reduced, effectively improving transmission efficiency.
[0014] In one embodiment of the present invention, the viewing angle scanning assembly includes: a telescopic rod, a trapezoidal mounting plate, and a plurality of scanning cameras. The telescopic rod is mounted on the top wall of the C-support frame. The trapezoidal mounting plate is mounted on the bottom end of the telescopic rod, and the plurality of scanning cameras are respectively mounted on the side walls and the top of the trapezoidal mounting plate.
[0015] The telescopic rod requires an external telescopic cylinder at its top to move it up and down, which in turn moves the trapezoidal mounting plate up and down, thereby adjusting the height of multiple scanning cameras. The trapezoidal mounting plate is trapezoidal in shape, and the multiple scanning cameras are respectively mounted on the side walls and top of the plate. By designing the trapezoidal mounting plate with a trapezoidal shape and mounting multiple scanning cameras on the side walls and top, the cameras mounted on the top of the plate take vertically downward photos of the trays on the conveyor belt, while the pair of cameras on the side walls take obliquely angled photos of the inner walls of the trays, thus reducing blind spots for image storage. Preferably, the side walls of the trapezoidal mounting plate are tilted at a 45-degree angle.
[0016] In one embodiment of the present invention, the tensioning assembly includes: multiple clearance slots, multiple pairs of fixing rods, and multiple tension springs. The multiple clearance slots are all carved into the inner sidewall of the operating frame and are located on one side of several of the rotating seats. The multiple pairs of fixing rods are respectively fixed to one end of the multiple clearance slots near the rotating seat and to the sidewall of the guide partition near the rotating arm. Both ends of the multiple tension springs are respectively fixed to the multiple pairs of fixing rods. One pair of fixing rods is used to fix both ends of the tension springs. Through the tensioning force of the tension springs, the guide partition is pulled closer to the inner wall of the operating frame. Since the guide partition is rotatably connected to the inner wall of the operating frame through multiple rotating arms, forming a parallelogram between the guide partition and the inner wall of the operating frame, pulling the guide partition closer to the inner wall of the operating frame also moves the guide partition in the opposite direction to the crossbar.
[0017] In one embodiment of the present invention, the measuring component includes a measuring plate and a moving groove. The measuring plate is fixed to the side wall of the guide partition near the rotating arm and is located on the side of one of the rotating seats away from the crossbar. The measuring plate is provided with a scale. The moving groove is carved into the side wall of the operating frame, and the end of the measuring plate away from the guide partition slides therein. The measuring component determines the distance the guide partition moves outward. When the guide partition is pulled towards the crossbar by the control lever, the guide partition drives the measuring plate to move from the moving groove towards the guide partition. The distance between the guide partition and the inner wall of the operating frame is determined by the length of the measuring plate extending outward from the moving groove, thereby determining the distance between a pair of guide partitions. In addition, while the guide partition drives the measuring plate to extend outward from the moving groove, it also drives the measuring plate to move towards the crossbar. Therefore, the moving groove is carved into a long strip shape to allow the measuring plate to move back, forth, left, and right within it.
[0018] In one embodiment of the present invention, the telescopic control assembly includes a lead screw and a control head. The lead screw rotates at one end of the partition near the control rod, and a rotating head is fixed to the other end of the lead screw located outside the partition. The control head is fixed to the end of the control rod located inside the partition, and the control head is threadedly connected to the lead screw. In use, a wrench is inserted into the rotating head, and then the rotating head drives the lead screw to rotate, causing the lead screw to move the control head, thereby causing the control head to telescopically move the control rod.
[0019] In one embodiment of the present invention, the connector is inverted T-shaped, and a third pulley is installed at both ends of the bottom of the connector. The bottom ends of the connector extend to both sides, and the friction generated when the connector slides on the side wall of the crossbar is reduced by a pair of third pulleys.
[0020] In one embodiment of the present invention, the fixing component includes: a slide groove, a threaded seat, a locking head, and a handle. The slide groove is carved into the crossbar. The threaded seat is fixed to the connector on the side away from the crossbar, and a threaded rod is threadedly connected to it. The end of the threaded rod near the crossbar slides within the slide groove. The locking head is fixed to the end of the threaded rod that passes through the slide groove. The handle is fixed to the end of the threaded rod away from the locking head. In use, the connector slides within the slide groove via the threaded rod, and the locking head is fixed at the end passing through the slide groove, thereby allowing the connector to slide on the slide groove. Furthermore, when it is necessary to fix the connector, the handle rotates the threaded rod, causing the locking head to lock against the inner wall of the crossbar, thereby fixing the connector.
[0021] In one embodiment of the present invention, a feed plate is fixed at the top center of the crossbar, and the top wall of the feed plate is flush with the top wall of the conveyor belt. The feed plate serves as a support when the tray is loaded onto the conveyor belt, and the tray slides onto the conveyor belt through the feed plate.
[0022] In one embodiment of the present invention, a plurality of fourth pulleys are installed on the feed plate to reduce the friction between the tray and the top wall of the feed plate. A plurality of first pulleys are evenly spaced on the sidewalls of the pair of guide partitions that are close to each other, thereby reducing the friction between the tray and the sidewalls of the pair of guide partitions. A plurality of second pulleys are evenly spaced on the bottom walls of the pair of guide partitions to reduce the friction between the bottom walls of the pair of guide partitions and the conveyor belt.
[0023] Compared with the prior art, the present invention provides a TRAY disc surface defect detection device. First, the transmission shaft drives the conveyor belt to rotate. After the TRAY disc is placed on the conveyor belt, it is transported forward by the conveyor belt. When the TRAY disc moves to the bottom of the C support frame, multiple scanning cameras scan the TRAY disc and then transmit the data to the image system for analysis to determine whether the TRAY disc is qualified. In addition, by setting the trapezoidal mounting plate to a trapezoidal shape, the problem of blind spots in the scanning camera is reduced.
[0024] Secondly, the control rod is kept stationary by sliding its connector at the outer end against the side wall of the crossbar. When the rotating head drives the lead screw to rotate, the lead screw, through the control head, causes the control rod to extend and retract on the guide partition. This pulls the guide partition towards the crossbar. Because the guide partition and the inner wall of the operating frame are connected by multiple rotating arms forming a parallelogram, pulling the guide partition towards the crossbar also brings a pair of guide partitions closer together. This method adjusts the spacing between the pair of guide partitions according to the width of the tray, thus guiding the tray during transport and preventing positional deviation.

Detailed Implementation
[0039] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.
[0040] like Figures 1 to 11 As shown, a TRAY disk surface defect detection device according to one embodiment of the present invention includes: an operating frame 1, a conveying component, a viewing angle scanning component, a center guiding mechanism 2, and a control mechanism.
[0041] like Figures 1 to 11 As shown, a C-support frame 107 is mounted on the operating frame 1. A transport assembly is mounted on the operating frame 1 for transporting the tray. A viewing angle scanning assembly is mounted on the C-support frame 107 for scanning the viewing angle of the tray.
[0042] The conveying assembly is used to move the tray forward. Additionally, the C-support frame 107 supports the viewing angle scanning assembly, which is used for taking pictures and scanning the tray.
[0043] like Figures 1 to 11 As shown, the central guide mechanism 2 is installed on the inner wall of the operating frame 1. The central guide mechanism 2 includes: a pair of guide partitions 201, multiple pairs of rotating arms 203, and a pair of measuring components 222. The pair of guide partitions 201 are respectively connected in parallel to the inner wall of the operating frame 1 through multiple pairs of rotating arms 203, and multiple tensioning components 204 are installed between the pair of guide partitions 201 and the inner wall of the operating frame 1. The pair of measuring components 222 are respectively installed on the pair of guide partitions 201.
[0044] Each pair of guide partitions 201 is arranged in a parallelogram shape with the inner wall of the operating frame 1 via multiple rotating arms 203. When the guide partitions 201 are pulled to move, the pair of guide partitions 201 always remain parallel to the inner wall of the operating frame 1. The tensioning assembly 204 is used to pull the guide partitions 201 closer to the inner wall of the operating frame 1 and to pull the guide partitions 201 to rotate in the opposite direction to the crossbar 220. The measuring assembly 222 is used to determine the distance between the guide partitions 201 and the inner wall of the operating frame 1.
[0045] In addition, multiple pairs of rotating seats 202 are fixed on the inner walls of a pair of guide partitions 201 and the operating frame 1, and the two ends of multiple pairs of rotating arms 203 are respectively rotatably connected to multiple pairs of rotating seats 202.
[0046] like Figures 1 to 11 As shown, the control mechanism is installed at one end of a pair of guide partitions 201. The control mechanism includes a pair of control levers 210, a crossbar 220, and a pair of connectors 214. The pair of control levers 210 slide on one end of the pair of guide partitions 201, and telescopic control components are installed between them and the guide partitions 201. The crossbar 220 is fixed to one end of the operating frame 1, and the pair of connectors 214 are fixed to the ends of the pair of control levers 210 that are close to each other, and slide on the crossbar 220. Fixing components are installed between the pair of connectors 214 and the crossbar 220.
[0047] Among them, the connector 214 slides on the cross bar 220 and can be fixed to the cross bar 220 through a fixing component. The telescopic control component is used to drive the control rod 210 to telescopically move on the guiding partition 201. However, since the connector 214 slides on the control rod 210, the connector 214 cannot move forward and backward. Therefore, when the telescopic control component drives the control rod 210 to telescopically move on the guiding partition 201, the control rod 210 pulls the guiding partition 201 in the opposite direction towards the cross bar 220. At the same time, when the control rod 210 pulls the guiding partition 201, the guiding partition 201 will move towards the center of the operating frame 1 under the push of multiple rotating arms 203. Thus, the guiding partition 201 drives the connector 214 to horizontally slide on the cross bar 220 through the control rod 210.
[0048] During specific use, first, it is necessary to adjust the distance between a pair of control rods 210 according to the width of the tray. When adjusting, the telescopic control component drives the control rod 210 to telescopically move on the guiding partition 201. Since the control rod 210 cannot move forward and backward, the control rod 210 pulls the guiding partition 201 in the opposite direction towards the cross bar 220. While pulling a pair of control rods 210 towards the cross bar 220, a pair of guiding partitions 201 push each other closer through multiple rotating arms 203 on them. While a pair of guiding partitions 201 push each other closer, they drive the connector 214 to horizontally slide on the cross bar 220 through the control rod 210. After the distance between a pair of cross bars 220 is adjusted, the connector 214 is fixed to the cross bar 220 through a fixing component. Thus, the guiding partition 201 is fixed. At the same time, a pair of guiding partitions 201 are under the action of the pulling force in the opposite direction to the cross bar 220 through multiple tensioning components 204 between them and the inner wall of the operating frame 1, and cooperate with the connector 214 fixed to the cross bar 220, thereby keeping the guiding partition 201 stable.
[0049] When adjusting the guiding partition 201, the measuring component 222 is used to determine the distance between a pair of guiding partitions 201. Finally, the tray is placed on the conveying component from one end of the conveying component close to the cross bar 220, and the conveying component drives the tray to be conveyed forward. During the movement of the tray, a pair of guiding partitions 201 on both sides of the tray guide the tray to prevent the tray from shifting in position during the conveying process. When the tray moves to the bottom of the C support frame 107, the tray is photographed and scanned by the perspective scanning component, and then the data information is transmitted to the image system to analyze whether the tray is qualified.
[0050] Such as Figures 1 to 5As shown, the conveying assembly includes: a pair of drive shafts 101, a conveyor belt 103, and multiple support rollers 105. The pair of drive shafts 101 are respectively mounted at both ends of the operating frame 1, and each is fixed with a pair of drive wheels 102. A pair of drive belts 104 are fixed to the inner wall of the conveyor belt 103, and the pair of drive belts 104 rotate on the two pairs of drive wheels 102 respectively. The drive wheels 102 and drive belts 104 are respectively provided with matching grooves and teeth. Multiple support rollers 105 are mounted between the pair of drive shafts 101 and fit against the inner top wall of the conveyor belt 103.
[0051] In use, one of the drive belts 104 requires an external drive motor 106. The drive belt 104 drives the conveyor belt 103 to rotate through a pair of drive pulleys 102 on it and a pair of drive belts 104 on the inner side wall of the conveyor belt 103. In addition, by setting corresponding grooves and teeth on the drive pulleys 102 and the drive belts 104 respectively, slippage between the drive pulleys 102 and the drive belts 104 is reduced, effectively improving the transmission efficiency.
[0052] like Figures 1 to 2 As shown, the viewing angle scanning assembly includes: a telescopic rod 108, a trapezoidal mounting plate 109, and multiple scanning cameras 110. The telescopic rod 108 is mounted on the top wall of the C-support frame 107. The trapezoidal mounting plate 109 is mounted on the bottom end of the telescopic rod 108. The multiple scanning cameras 110 are respectively mounted on the side walls and top of the trapezoidal mounting plate 109.
[0053] The top of the telescopic rod 108 needs to be connected to an external telescopic cylinder 111 to drive the telescopic rod 108 to move up and down. The telescopic rod 108 drives the trapezoidal mounting plate 109 to move up and down, thereby adjusting the height of multiple scanning cameras 110.
[0054] Furthermore, the trapezoidal mounting plate 109 is trapezoidal in shape, and multiple scanning cameras 110 are respectively mounted on the side walls and top of the trapezoidal mounting plate 109. By providing a trapezoidal shape for the trapezoidal mounting plate 109 and mounting multiple scanning cameras 110 on the side walls and top of the trapezoidal mounting plate 109, the multiple scanning cameras 110 mounted on the top of the trapezoidal mounting plate 109 are used to take pictures of the tray on the conveyor belt 103 vertically downwards, while the pair of scanning cameras 110 mounted on the side walls of the trapezoidal mounting plate 109 are used to take pictures of the inner groove wall of the tray at an angle, thereby reducing the blind spots for storage. Preferably, the inclination angle of the side walls of the trapezoidal mounting plate 109 is forty-five degrees.
[0055] like Figures 3 to 11As shown, the tensioning assembly 204 includes: multiple clearance slots 205, multiple pairs of fixing rods 206, and multiple tension springs 207. The multiple clearance slots 205 are all carved into the inner side wall of the operating frame 1 and are located on one side of several of the rotating seats 202. The multiple pairs of fixing rods 206 are respectively fixed to one end of the multiple clearance slots 205 near the rotating seat 202 and to the side wall of the guide partition 201 near the rotating arm 203. The multiple tension springs 207 are respectively fixed at both ends to the multiple pairs of fixing rods 206. A pair of fixed rods 206 are used to fix the two ends of the tension spring 207 to them respectively. Through the tension of the tension spring 207, the guide partition 201 is pulled closer to the inner wall of the operating frame 1. Since the guide partition 201 is rotatably connected to the inner wall of the operating frame 1 through multiple rotating arms 203, the guide partition 201 and the inner wall of the operating frame 1 form a parallelogram. Therefore, while pulling the guide partition 201 closer to the inner wall of the operating frame 1, the guide partition 201 is also driven to move in the opposite direction to the crossbar 220.
[0056] like Figure 6 and Figure 7 As shown, the measuring assembly 222 includes a measuring plate 223 and a moving groove 224. The measuring plate 223 is fixed to the side wall of the guide partition 201 near the rotating arm 203, and is located on the side of one of the rotating seats 202 away from the crossbar 220. The measuring plate 223 is provided with a scale. The moving groove 224 is carved into the side wall of the operating frame 1, and the end of the measuring plate 223 away from the guide partition 201 slides in it. The measuring assembly 222 is used to determine the distance the guide partition 201 moves outward. When the control lever 210 pulls the guide partition 201 to move towards the crossbar 220, the guide partition 201 drives the measuring plate 223 to move from the moving groove 224 towards the guide partition 201. The distance between the guide partition 201 and the inner wall of the operating frame 1 is determined by the length of the measuring plate 223 extending out of the moving groove 224, thereby determining the distance between a pair of guide partitions 201. In addition, while the guide partition 201 drives the measuring plate 223 to extend outward from the moving groove 224, it also drives the measuring plate 223 to move in the direction of the crossbar 220. Therefore, the moving groove 224 is cut into a long strip shape so that the measuring plate 223 can move back and forth and left and right inside it.
[0057] like Figures 7 to 9As shown, the telescopic control assembly includes a lead screw 212 and a control head 211. The lead screw 212 rotates at one end of the partition 201 near the control rod 210, and a rotating head 213 is fixed to the other end of the lead screw 212 located outside the partition 201. The control head 211 is fixed to the end of the control rod 210 located inside the partition 201, and the control head 211 is threadedly connected to the lead screw 212. In use, a wrench needs to be inserted into the rotating head 213, and then the rotating head 213 drives the lead screw 212 to rotate, causing the lead screw 212 to move the control head 211, thereby causing the control head 211 to move the control rod 210 telescopically.
[0058] like Figures 7 to 8 As shown, the connector 214 is inverted T-shaped, and a third pulley 219 is installed at both ends of the bottom of the connector 214. The bottom ends of the connector 214 extend to both sides, and the friction generated when the connector 214 slides on the side wall of the crossbar 220 is reduced by a pair of third pulleys 219.
[0059] like Figures 7 to 11 As shown, the fixing assembly includes: a slide groove 211, a threaded seat 215, a locking head 218, and a handle 217. The slide groove 211 is carved into the crossbar 220. The threaded seat 215 is fixed to the connector 214 on the side away from the crossbar 220, and a threaded rod 216 is threaded onto it. The end of the threaded rod 216 near the crossbar 220 passes through the slide groove 221. The locking head 218 is fixed to the end of the threaded rod 216 that passes through the slide groove 221. The handle 217 is fixed to the end of the threaded rod 216 away from the locking head 218. In use, the connector 214 slides into the groove 221 via the threaded rod 216, and a locking head 218 is fixed at one end of the groove 221, thereby allowing the connector 214 to slide on the groove 221. When it is necessary to fix the connector 214, the threaded rod 216 is rotated by the handle 217, so that the locking head 218 is locked on the inner wall of the crossbar 220, thereby fixing the connector 214.
[0060] like Figures 1 to 6 As shown, a feed plate 225 is fixed to the top center of the crossbar 220, and the top wall of the feed plate 225 is flush with the top wall of the conveyor belt 103. The feed plate 225 serves as a support when the tray is loaded onto the conveyor belt 103, and the tray slides onto the conveyor belt 103 through the feed plate 225. Multiple fourth pulleys 226 are installed on the feed plate 225 to reduce the friction between the tray and the top wall of the feed plate 225.
[0061] like Figures 7 to 11As shown, multiple first pulleys 208 are evenly spaced on the sidewalls of a pair of guide partitions 201 that are close to each other. The multiple first pulleys 208 reduce the friction between the tray and the sidewalls of the pair of guide partitions 201. Multiple second pulleys 209 are evenly spaced on the bottom wall of the pair of guide partitions 201. The multiple second pulleys 209 reduce the friction between the bottom wall of the pair of guide partitions 201 and the conveyor belt 103.
[0062] Working principle: First, the spacing between a pair of control levers 210 needs to be adjusted according to the width of the tray. During adjustment, a pair of rotating heads 213 are turned with a wrench. The rotating heads 213 drive the control levers 210 to extend and retract on the guide plate 201 via the lead screw 212 and the control head 211. Since the control levers 210 cannot move back and forth, they pull the guide plate 201 towards the horizontal bar 220. While pulling the pair of control levers 210 towards the horizontal bar 220, the pair of guide plates 201 push the pair of horizontal bars 220 closer together via multiple rotating arms 203. As the pair of horizontal bars 220 approach each other, the connecting head 214 slides horizontally on the horizontal bar 220 via the control levers 210. After the spacing between the pair of crossbars 220 is adjusted, the handle 217 is used to rotate the threaded rod 216 on the threaded seat 215, causing the locking head 218 to lock onto the inner wall of the crossbar 220, thereby fixing the connector 214 to the crossbar 220 and thus fixing the guide partition 201. At the same time, the pair of guide partitions 201 are fixed to the crossbar 220 by the pull force of multiple tension springs 207 between them and the inner wall of the operating frame 1, thus keeping the guide partitions 201 stable.
[0063] When adjusting the guide partition 201, the length of the measuring plate 223 extending from the moving groove 224 is determined by measuring the scale on the measuring plate 223, thereby determining the distance between the guide partition 201 and the inner wall of the operating frame 1, and thus determining the distance between a pair of guide partitions 201.
[0064] Finally, the tray is slid from the feed plate 225 onto the conveyor belt 103, and then conveyed forward by the conveyor belt 103. During the movement of the tray, a pair of guide baffles 201 on both sides guide the tray to prevent positional deviation during transport. After the tray moves to the bottom of the C support frame 107, multiple scanning cameras 110 scan the tray and then transmit the data to the image system for analysis to determine if the tray is qualified.
