Description

Technical Field

[0001] This invention relates to the field of chip inspection technology, specifically to a chip appearance inspection, classification, and rejection device and method based on a vision module. Background Technology

[0002] A chip is an integrated circuit carrier made of semiconductor materials. By integrating transistors and electronic components on a tiny wafer, it is the core of modern electronic devices. It can process and calculate information, store data, convert signals and control devices. It has an indispensable function in the fields of computers, mobile phones and communications. In order to detect whether the appearance of a chip is qualified, a chip appearance inspection, classification and rejection device and method based on vision module is needed.

[0003] A chip appearance inspection, classification, and rejection device based on a vision module refers to an industrial equipment that uses a high-resolution camera and a light source vision module to acquire chip images, uses AI algorithms or image processing chips to identify and classify scratches and edge defects, and then links with a mechanical mechanism to automatically reject unqualified products, thereby achieving high-speed automated inspection and sorting of chip appearance.

[0004] Currently available chip appearance inspection and sorting rejection equipment consists of a positioning structure and a transmission structure. During use, the chip is placed in a positioning frame, and the transmission structure moves the positioning frame to the inspection area so that the visual inspection element can inspect the chip's appearance. To improve the chip's fixing stability, existing technologies use a clamping structure to limit the chip's position. At the same time, gear transmission is used to drive the positioning frame to rotate in order to achieve chip transfer. However, this method can only inspect the top of the chip and is difficult to inspect different positions. When inspecting defects on the side of the chip, it can lead to missed detections, which affects chip quality control and reduces the reliability of the device. Summary of the Invention

[0008] Preferably, the positioning mechanism includes an electric telescopic rod, which is fixedly connected to the front middle of the base. A spring rod is rotatably connected to the inner side of the hollow tube II. One end of the spring rod is fixedly connected to a push plate, and the other end of the spring rod passes through the positioning frame and is rotatably connected to a clamping plate. Multiple reserved slots are provided on the outer side of the positioning frame, and the reserved slots are slidably connected to the clamping plate. A positioning component is provided at the bottom of the base, and a gripping component is provided at the bottom outer side of the base.

[0009] Preferably, the feeding mechanism includes a mounting cover and a belt. The mounting cover is fixedly connected to the rear side of the base. Electric wheels are rotatably connected to the inner circumference of the mounting cover. The multiple electric wheels are connected to each other via belt drive. A limit rod is fixedly connected to the front side of the upper electric wheel, and the front side of the limit rod penetrates the base. A rotating rod is fixedly connected to the front side of the lower electric wheel. A telescopic block is rotatably connected to the outer side of the rotating rod. A top block is rotatably connected to the top of the telescopic block. An auxiliary component is provided on the outer side of the mounting cover, and a protective component is provided on the top of the mounting cover.

[0010] Preferably, the power assembly includes a gear 1, and multiple gears 1 are rotatably connected around the inside of the electric rotating ring. The outer side of the gear 1 passes through the electric rotating ring and is fixedly connected to the corresponding positioning frame. A connecting column is fixedly connected to the top center of the base. A motor is fixedly connected to the front side of the connecting column. A gear 2 is fixedly connected to the output end of the motor. The gear 2 meshes with the front gear 1.

[0011] Preferably, the fixing component includes a fixing column, which is rotatably connected to the top of the connecting column. A mounting plate is fixedly connected to the top of the fixing column, and the inner side of the mounting plate is fixedly connected to the visual inspection camera.

[0012] Preferably, the positioning component includes a second mounting plate, two of which are fixedly connected to the left and right bottom sides of the base, and positioning blocks are fixedly connected to the front and rear sides of the second mounting plate.

[0013] Preferably, the gripping assembly includes a handle, which is disposed on the top of the mounting plate two, and screws are threadedly connected to both the front and rear sides of the handle, and the handle is threadedly connected to the mounting plate two by the screws.

[0014] Preferably, the auxiliary component includes an observation window, which is located on the front right side of the mounting cover, and brackets are fixedly connected to the left and right sides of the interior of the mounting cover.

[0015] Preferably, the protective component includes a movable door, which is disposed on the top of the mounting cover. Hinges are fixedly connected to the left and right sides of the top of the movable door, and the movable door is rotatably connected to the mounting cover through the hinges.

[0016] The method for using a chip appearance inspection, classification, and rejection device based on a vision module includes the following steps:

[0017] S1. First, place the chip into the positioning frame, then start the electric rotating ring to drive the electric rotating ring and the hollow tube 2 on it to rotate. In conjunction with the rotation of the rotating ring and the hollow tube 1, multiple positioning frames rotate simultaneously. When the positioning frame moves the chip under the visual inspection camera, the appearance of the chip can be inspected.

[0018] S2. When the electric rotating ring rotates, gear one will also move. When gear one meshes with gear two, the motor is started to drive gear two to rotate, which in turn causes gear one and the positioning frame to rotate, adjusting the chip detection angle.

[0019] S3. The rotating ring drives the spring rod and push plate to move. When the push plate reaches the electric telescopic rod, the telescopic rod pushes the push plate to stretch the spring rod, causing the clamping plate to move. During testing, chips of different specifications are fixed. If a faulty chip is found, the clamping plate is released to allow it to be discharged into the discharge port.

[0020] S4. After the chip to be tested is placed in the mounting cover, it will be supported by the limit rod. Start the electric wheel and ensure synchronous operation through belt drive. The upper electric wheel drives the limit rod to rotate, and the chip falls into the positioning frame. The lower electric wheel drives the telescopic block and the top block to securely install the chip in the positioning frame.

[0021] This invention provides a chip appearance inspection, classification, and rejection device and method based on a vision module. It has the following beneficial effects:

[0022] 1. This invention improves the reliability of the device by placing the chip in the positioning frame, starting the electric rotating ring to drive the hollow tube, rotating ring and positioning frame to rotate, and moving the positioning frame under the visual inspection camera to inspect the appearance; the rotation of the electric rotating ring drives the drive gear and driven gear to mesh, and the motor starts the driven gear to drive the spring rod and positioning frame to rotate, thereby adjusting the chip detection angle.

[0023] 2. This invention uses a rotating ring to drive a spring rod and a push plate to move. When the push plate reaches the corresponding position of the electric telescopic rod, the telescopic rod is activated. The thrust causes the spring rod to extend and the clamping plate to move. During testing, the clamping plate and the spring rod's thrust fix chips of different specifications in the positioning frame. When a faulty chip is detected, the push plate is controlled in reverse, and the clamping plate opens to allow the chip to fall into the discharge port, completing the fixing and sorting, thereby improving the practicality of the device.

[0024] 3. In this invention, after the chip to be tested is placed in the mounting cover, it is supported by the limiting rod. The electric wheel is started and the upper and lower electric wheels rotate synchronously through belt drive. When the upper electric wheel drives the limiting rod to turn downward, the chip falls to the bottom positioning frame. The lower electric wheel drives the rotating rod and the telescopic block to rotate. The telescopic block pushes the top block to position the fallen chip in the middle of the inner side of the positioning frame, providing support for testing, thereby improving the convenience of the device.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1:

[0036] Reference Figure 1 , Figure 4 and Figure 6 This invention provides a chip appearance inspection, classification, and rejection device and method based on a vision module, including a base 1, a vision inspection camera 5 on the top of the base 1, the vision inspection camera 5 being able to inspect the chip, an inspection mechanism 2 on the upper side of the base 1 for raising the inspection angle, a positioning mechanism 3 on the outer side of the base 1 for fixing chips of different specifications, and a feeding mechanism 4 on the rear side of the base 1 for timely replenishment of materials.

[0037] The testing mechanism 2 includes an electric rotating ring 21, which is rotatably connected to the top center of the base 1. Hollow tubes 24 are rotatably connected to the outer periphery of the electric rotating ring 21. A rotating ring 22 is rotatably connected to the top outer side of the base 1. Hollow tubes 23 are rotatably connected to the inner periphery of the rotating ring 22. Positioning frames 25 are fixedly connected between adjacent hollow tubes 23 and the rotating ring 22. A discharge port 26 is provided on the front inner side of the base 1. A power assembly 27 is provided on the inner side of the electric rotating ring 21, and a fixing assembly 28 is provided on the top of the base 1. The power assembly 27 includes gears 271, and multiple gears 271 rotate respectively. The electric rotating ring 21 is connected to the inside of the electric rotating ring 21. The rotation of the electric rotating ring 21 will drive multiple gears 271 to rotate. The outer side of the gear 271 passes through the electric rotating ring 21 and is fixedly connected to the corresponding positioning frame 25. When the gear 271 rotates, it will drive the spring rod 33 to rotate synchronously. The top center of the base 1 is fixedly connected to the connecting column 274. The front side of the connecting column 274 is fixedly connected to the motor 272. The output end of the motor 272 is fixedly connected to the gear 273. The gear 273 meshes with the front gear 271. Starting the motor 272 can drive the gear 273 to rotate and drive the gear 271 meshing with it.

[0038] Specifically, after placing the chip to be tested in the positioning frame 25, the electric rotating ring 21 is started to drive the hollow tube 24 on it to move simultaneously, so that the positioning frame 25 drives the chip to rotate to the area below the visual inspection camera 5 for appearance image acquisition and inspection. At this time, when the gear 271 on the electric rotating ring 21 meshes with the fixed gear 273, the motor 272 is started to drive the gear 271 and the fixed gear 273 to rotate, thereby driving the positioning frame 25 and the chip inside to adjust their angles, realizing multi-angle detection and automatic control of the chip.

[0039] Reference Figure 1 , Figure 3 and Figure 7 The positioning mechanism 3 includes an electric telescopic rod 31, which is fixedly connected to the middle of the front side of the base 1. A spring rod 33 is rotatably connected to the inner side of the hollow tube 24. One end of the spring rod 33 is fixedly connected to a push plate 32, and the other end of the spring rod 33 passes through the positioning frame 25 and is rotatably connected to a clamping plate 35. The elasticity of the spring rod 33 can push the clamping plate 35 to fix the chip, and by pulling the push plate 32, the spring rod 33 can be actively pulled to release the clamping plate 35. Multiple reserved slots 34 are provided on the outer side of the positioning frame 25. The reserved slots 34 are slidably connected to the clamping plate 35. The clamping plate 35 will slide along the reserved slots 34 to fix the chip in the positioning frame 25. A positioning component 36 is provided at the bottom of the base 1, and a gripping component 37 is provided at the bottom of the outer side of the base 1.

[0040] Specifically, as the rotating ring 22 rotates, the spring rod 33 and push plate 32 connected to it will move accordingly. Then, when the push plate 32 moves to the corresponding position of the electric telescopic rod 31, the electric telescopic rod 31 is activated to apply a pushing force to the push plate 32. After the push plate 32 is subjected to force, it will drive the spring rod 33 to extend, so that the clamping plate 35 connected to the spring rod 33 will also move. During the chip detection process, the pushing force generated by the clamping plate 35 and the spring rod 33 can fix chips of different specifications in the positioning frame 25. When a faulty chip is detected, the push plate 32 is moved in the opposite direction to open the clamping plate 35, loosen the fixation of the faulty chip, and allow it to fall smoothly into the discharge port 26, thereby facilitating the fixing and sorting of chips.

[0041] Reference Figure 2 , Figure 3 and Figure 8 The feeding mechanism 4 includes a mounting cover 41 and a belt 43. The mounting cover 41 is fixedly connected to the rear side of the base 1. Electric wheels 42 are rotatably connected to the inside of the mounting cover 41. Multiple electric wheels 42 are connected to each other by a belt 43. The belt 43 can improve the synchronicity of the rotation of the electric wheels 42. A limit rod 45 is fixedly connected to the front side of the upper electric wheel 42. The front side of the limit rod 45 passes through the base 1. When the upper electric wheel 42 rotates, it will drive the limit rod 45 to rotate. A rotating rod 44 is fixedly connected to the front side of the lower electric wheel 42. A telescopic block 48 is rotatably connected to the outside of the rotating rod 44. When the lower electric wheel 42 rotates, it will drive the rotating rod 44 to rotate, which will drive the telescopic block 48 to rotate. A top block 49 is rotatably connected to the top of the telescopic block 48. As the telescopic block 48 rotates and extends, it can push the top block 49 to move up and down. An auxiliary component 46 is provided on the outside of the mounting cover 41. A protective component 47 is provided on the top of the mounting cover 41.

[0042] Specifically, after multiple chips to be tested are placed inside the mounting cover 41, they are supported by the limiting rod 45. After the electric wheel 42 is started, the belt 43 drives the multiple electric wheels 42 to rotate synchronously. The upper electric wheel 42 drives the limiting rod 45 to rotate. When it turns downward, the chip loses support and falls into the bottom positioning frame 25 for storage. At the same time, the rotation of the lower electric wheel 42 drives the rotating rod 44 and the telescopic block 48 to rotate. During the rotation and extension process, the telescopic block 48 pushes the top block 49 to move, so that when the chip falls into the positioning frame 25 for storage, the top block 49 can position the chip in a suitable installation position in the middle of the inner side of the positioning frame 25, providing stable support for subsequent testing.

[0043] Reference Figure 2 , Figure 3 and Figure 5The fixing component 28 includes a fixing post 281, which is rotatably connected to the top of the connecting post 274. A mounting plate 282 is fixedly connected to the top of the fixing post 281. The inner side of the mounting plate 282 is fixedly connected to the visual inspection camera 5. The visual inspection camera 5 can be fixed or installed through the fixing post 281 and the mounting plate 282.

[0044] Specifically, the rotatable fixed post 281 and its mounting plate 282 facilitate the installation and adjustment of the visual inspection camera 5.

[0045] Reference Figure 3 , Figure 6 and Figure 7 The positioning component 36 includes two mounting plates 361, which are fixedly connected to the bottom left and right sides of the base 1 respectively. Positioning blocks 362 are fixedly connected to the front and rear sides of the mounting plates 361. By inserting threaded parts into the positioning blocks 362 on the mounting plates 361, the device can be easily positioned and installed. The gripping component 37 includes a handle 371, which is located on the top of the mounting plates 361. Screws 372 are threadedly connected to the front and rear sides of the handle 371. The handle 371 is threadedly connected to the mounting plates 361 by the screws 372. The screws 372 can fix the handle 371 to the top of the mounting plates 361, thereby facilitating the installation and fixation of the device.

[0046] Specifically, by inserting a threaded part into the positioning block 362 on the outside of the mounting plate 361, the device can be easily fixed. The handle 371 installed by the screw 372 can be easily handled and stored by gripping the device.

[0047] Reference Figure 1 , Figure 3 and Figure 8 The auxiliary component 46 includes an observation window 461, which is located on the front right side of the mounting cover 41. The number of chips stored inside the mounting cover 41 can be observed through the observation window 461. The mounting cover 41 is fixedly connected to the left and right sides of the interior, and the mounting cover 41 can be supported and fixed by the brackets 462. The protective component 47 includes a movable door 471, which is located on the top of the mounting cover 41. The movable door 471 is fixedly connected to the left and right sides of the top of the movable door 471. The movable door 471 is rotatably connected to the mounting cover 41 by the hinges 472. Opening and closing the movable door 471 by the hinges 472 can facilitate the protection of the inside of the device.

[0048] Specifically, the observation window 461 allows for easy observation of the number of chips stacked inside the mounting cover 41, while the bracket 462 enhances the structural strength and stability of the mounting cover 41. The hinge 472 allows for the opening and closing of the movable door 471 to prevent external dust from entering the device when it is not in use.

[0049] Example 2:

[0050] The method for using a chip appearance inspection, classification, and rejection device based on a vision module includes the following steps:

[0051] S1. First, place the chip into the positioning frame 25, then start the electric rotating ring 21 to drive the electric rotating ring 21 and the hollow tube 24 on it to rotate. In conjunction with the rotation of the rotating ring 22 and the hollow tube 23, multiple positioning frames 25 rotate simultaneously. When the positioning frame 25 moves the chip to the underside of the visual inspection camera 5, the appearance of the chip can be inspected.

[0052] S2. When the electric rotating ring 21 rotates, gear 1 271 will also move. When gear 1 271 meshes with gear 2 273, the motor 272 is started to drive gear 2 273 to rotate, thereby causing gear 1 271 and positioning frame 25 to rotate and adjust the chip detection angle.

[0053] S3. The rotating ring 22 drives the spring rod 33 and the push plate 32 to move. The push plate 32 reaches the electric telescopic rod 31. The telescopic rod pushes the push plate 32 to stretch the spring rod 33, causing the clamping plate 35 to move. During testing, chips of different specifications are fixed. If a faulty chip is found, the clamping plate 35 is released to allow it to be discharged into the discharge port 26.

[0054] S4. After the chip to be tested is placed in the mounting cover 41, it will be supported by the limiting rod 45. Start the electric wheel 42, and ensure synchronous operation through the belt 43. The upper electric wheel 42 drives the limiting rod 45 to rotate, and the chip falls into the positioning frame 25. The lower electric wheel 42 drives the telescopic block 48 and the top block 49 to securely install the chip in the positioning frame 25.

[0055] Working principle: The chip to be detected is placed in the positioning frame 25. Then, by starting the electric rotating ring 21, the hollow tube 24 on it can be moved simultaneously. At this time, in conjunction with the rotation of the rotating ring 22 and the hollow tube 23 on it, multiple positioning frames 25 can be rotated simultaneously. When the positioning frame 25 and the internal chip move to the bottom of the visual inspection camera 5, the appearance of the chip can be inspected by the visual inspection camera 5. Then, as the electric rotating ring 21 rotates, the gear 271 on it will also move. When the gear 271 meshes with the gear 273, the starting motor 272 can drive the gear 273 to rotate, thereby driving the corresponding gear 271 and the spring rod 33 fixed to it to rotate, thereby driving the corresponding positioning frame 25 to rotate, thus adjusting the angle of the chip being detected during the inspection.

[0056] Furthermore, the rotation of the rotating ring 22 can drive the spring rod 33 and the push plate 32 on it to move. When the push plate 32 moves to the electric telescopic rod 31, the electric telescopic rod 31 is activated to push the push plate 32 to pull the spring rod 33 to extend, causing the clamping plate 35 on it to move accordingly. During the inspection, the clamping plate 35 and the spring rod 33 can push the chips of different specifications to be fixed in the positioning frame 25. After the faulty chip is detected, the movement of the push plate 32 will unfold the clamping block 35 to release the fixed chip and discharge it into the discharge port 26, so as to fix the chip and classify it.

[0057] Finally, by placing multiple chips inside the mounting cover 41, they can be supported by the limiting rod 45. Subsequently, the transmission of the belt 43 can improve the synchronization and stability of the multiple electric wheels 42 when they are turned on. As the upper electric wheel 42 rotates, it can drive the limiting rod 45 to rotate. When the limiting rod 45 rotates to the downward direction, the chip that loses support will fall into the corresponding positioning frame 25 at the bottom for storage. At the same time, as the lower electric wheel 42 rotates, it can drive the rotating rod 44 and its telescopic block 48 to rotate. As the telescopic block 48 rotates and extends, it pushes the top block 49 to move, so that the chip can be installed in the positioning frame 25 by the top block 49 to provide support when installing the chip.

10. A method for using a chip appearance inspection, classification, and rejection device based on a vision module, characterized in that, The chip appearance inspection, classification, and rejection device based on any one of claims 1-9 includes the following steps: S1. First, place the chip into the positioning frame (25), then start the electric rotating ring (21) to drive the electric rotating ring (21) and the hollow tube two (24) on it to rotate. In conjunction with the rotation of the rotating ring (22) and the hollow tube one (23), multiple positioning frames (25) rotate at the same time. When the positioning frame (25) moves the chip to the underside of the visual inspection camera (5), the appearance of the chip can be detected. S2. When the electric rotating ring (21) rotates, gear one (271) will also move. When gear one (271) meshes with gear two (273), start the motor (272) to drive gear two (273) to rotate, thereby causing gear one (271) and the positioning frame (25) to rotate and adjust the chip detection angle. S3. The rotating ring (22) drives the spring rod (33) and the push plate (32) to move. The push plate (32) reaches the electric telescopic rod (31). The telescopic rod pushes the push plate (32) to stretch the spring rod (33), causing the clamping plate (35) to move. During the test, chips of different specifications are fixed. If a faulty chip is found, the clamping plate (35) is released and discharged into the discharge port (26). S4. After the chip to be tested is placed in the mounting cover (41), it will be supported by the limiting rod (45). Start the electric wheel (42) and ensure synchronous operation through the belt (43). The upper electric wheel (42) drives the limiting rod (45) to rotate, and the chip falls into the positioning frame (25). The lower electric wheel (42) drives the telescopic block (48) and the top block (49) to securely install the chip in the positioning frame (25).
