Technical Field
[0001] This utility model relates to the field of chip sorting device technology, and in particular to a chip sorting device integrating photoelectric detection. Background Technology
[0002] Integrated photoelectric detection chip sorting devices are mainly used to achieve automated screening and classification of chips. By integrating photoelectric detection modules and mechanical sorting mechanisms, an integrated device is constructed that can accurately identify chip appearance defects and performance parameter differences and complete corresponding sorting operations. It is widely used in the post-processing testing of semiconductor chip manufacturing, screening for recycling and reuse of electronic components, grading and screening of consumer electronics chips, quality control of automotive electronic chips, and sorting of finished products after integrated circuit packaging.
[0003] The integrated photoelectric detection chip sorting device mainly consists of a photoelectric detection module and a mechanical sorting mechanism. Its working principle is to transport the chips to be sorted to the detection area by a conveyor belt. The optical sensor and image acquisition unit acquire the chip's appearance and key parameter information. The signal processing circuit and the main control device analyze and determine whether the chip is qualified. Then, the main control device sends an instruction to the mechanical sorting mechanism, and the sorting robot arm pushes the chip to the corresponding classification and storage channel, thereby realizing automated, high-precision detection and sorting of chips.
[0004] Existing chip sorting devices with integrated photoelectric detection have limitations in correcting misaligned chips. This causes chips to easily deviate from the scanning area during transport, resulting in missed detections due to positional deviations and misjudging good products. Consequently, the accuracy and overall efficiency of chip sorting are affected. To address these issues, a chip sorting device with integrated photoelectric detection is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a chip sorting device with integrated photoelectric detection, which aims to improve the problem that some existing devices cannot correct misaligned chips.

As a further description of the above technical solution: The telescopic column is externally slidably connected to the inside of the support plate three, and the left end of the fixing block two is fixedly connected to the right end of the support frame one. As a further description of the above technical solution: The gripping mechanism includes a support plate 1, the left end of which is fixedly connected to the rear end of the support frame 1, a control unit is fixedly connected to the top end of the support plate 1, a telescopic rod is fixedly connected to the top end of the control unit, a connecting rod 1 is fixedly connected to the top end of the telescopic rod, a connecting rod 2 is fixedly connected to the left end of the connecting rod 1, an adsorption plate is fixedly connected to the left end of the connecting rod 2, and a collection box is fixedly connected to the rear end of the support frame 1.

As a further description of the above technical solution: The driven column has an arc-shaped groove on its outside, and the support rod is slidably connected to the inside of the fixed plate.
[0007] This utility model has the following beneficial effects: 1. In this utility model, the telescopic column driven by the bidirectional cylinder moves the fixed block one, which in turn moves the connecting rod one to the right. This causes the connecting rod one to rotate around the fixed block two as the axis, pushing the connecting column to move the auxiliary plate to the right. When the auxiliary plate moves to the designated position and contacts the carrier plate, it pushes the offset carrier plate back to the designated area in the center of the conveyor belt, ensuring that the carrier plate enters the scanning area of the scanner stably and reducing the problems of missed detection defects and misjudged good products caused by position deviation.
[0008] 2. In this utility model, the fixed column driven by the motor drives the rotating shaft to rotate, which in turn drives the driven column to rotate. The rotation of the driven column causes the connecting rod four to slide in the arc groove on its outside, which in turn drives the support rod to slide left and right, and drives the brush to slide back and forth on the outside of the bearing plate, thereby realizing the function of cleaning dust and hard particles on the surface of the bearing plate, reducing the situation where the scanner misjudges good products as defective products, and improving the accuracy of detection.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Example 1: A chip sorting device integrating photoelectric detection, as described above. Figures 1 to 3 The device includes a support frame 1, which serves as the load-bearing foundation of the device. A support frame 2 is fixedly connected to the outside of the support frame 1. The support frame 2 is used to fix and support the scanner 3, so that the scanner 3 can be stably positioned directly above the designated position on the conveyor belt 55, ensuring that the scanner 3 can accurately scan the chips on the carrier plate 56. The top of the support frame 2 is fixedly connected to the scanner 3, which can perform photoelectric detection on the chips on the carrier plate 56 during transportation, screen out unqualified chips through scanning and mark them, and transmit the position data of the unqualified chips to the control unit 42. A gripping mechanism 4 is provided at the rear end of the support frame 1. The gripping mechanism 4 includes a support plate 41. The left end of the support plate 41 is fixedly connected to the rear end of the support frame 1. The two are fixed by welding. The support plate 41 provides an installation foundation for the control unit 42, ensuring that the control unit 42 maintains a fixed position during operation. A control unit 42 is fixedly connected to the top of the support plate 41. The control unit 42 is the control core of the gripping mechanism 4. It can receive the position data of the unqualified chip transmitted by the scanner 3 and drive the telescopic rod 43 to move. The telescopic rod 43 is fixedly connected to the top of the control unit 42. The telescopic rod 43 can move in extension and retraction under the drive of the control unit 42, thereby driving the connecting rod 44 to move and providing power for the position movement of the adsorption plate 46. The top of the telescopic rod 43 is fixedly connected to the connecting rod 44. The connecting rod 44 can synchronously transmit the movement of the telescopic rod 43 to the connecting rod 45, ensuring that the adsorption plate 46 can be adjusted to the designated gripping position with the telescopic rod 43. The left end of the connecting rod 44 is fixedly connected to the connecting rod 45. The connecting rod 45 is used to connect the connecting rod 44 and the adsorption plate 46 to ensure the stability when adsorbing the chip. The left end of the connecting rod 45 is fixedly connected to the adsorption plate 46. The adsorption plate 46 can generate negative pressure suction, which can stably adsorb the unqualified chip and transfer it to the inside of the collection box 47 to complete the sorting of unqualified chips. A drive mechanism 5 is provided at the left end of the support frame 1. The drive mechanism 5 provides power for the rotation of the conveyor belt 55, driving the carrier plate 56 to move along a specified path within the device. The drive mechanism 5 includes a support plate 2 51. The right end of the support plate 2 51 is fixedly connected to the left end of the support frame 1, and the two are fixed by welding. The support plate 2 51 provides an installation base for the motor 52. The top end of the support plate 2 51 is fixedly connected to the motor 52, which can drive the fixed column 53 to rotate. The drive end of the motor 52 is fixedly connected to the fixed column 53. The fixed column 53 can transmit the power of the motor 52 to the rotating shaft 54. The right end of the fixed column 53 is fixedly connected to the rotating shaft 54. The rotating shaft 54 rotates under the drive of the fixed column 53, thereby driving the conveyor belt 55 to rotate synchronously. The outside of the rotating shaft 54 is fitted with the conveyor belt 55. The conveyor belt 55 moves under the drive of the rotating shaft 54, which can drive the carrier plate 56 to move. The top end of the conveyor belt 55 is slidably connected to the carrier plate 56, which is used to place the chips to be tested and sorted. Specifically, the motor 52 is started, and the motor 52 drives the rotating shaft 54 to rotate the conveyor belt 55 through the driving fixed column 53. The carrier plate 56 is placed on the top of the conveyor belt 55. The scanner 3 scans and filters out unqualified chips and marks them. At the same time, the position data of the unqualified chips is transmitted to the control unit 42. The control unit 42 drives the telescopic rod 43 to move the connecting rod 44, which in turn causes the connecting rod 45 to move the adsorption plate 46, adsorb the unqualified chips on the surface of the carrier plate 56 and put them into the collection box 47 for subsequent processing.
[0013] A correction mechanism 6 is provided at the bottom of the support frame 1. The correction mechanism 6 can correct the position of the offset carrier plate 56 before it is transported to the scanner 3. A cleaning mechanism 7 is provided at the right end of the support frame 1. The cleaning mechanism 7 can clean the dust and hard particles on the surface of the carrier plate 56 before it enters the scanning area, thereby improving the detection accuracy. The correction mechanism 6 includes a support plate 3 61. The top of the support plate 3 61 is fixedly connected to the bottom of the support frame 1. The support plate 3 61 provides a mounting base for the bidirectional cylinder 62. The bidirectional cylinder 62 is fixedly connected inside the support plate 3 61, which can drive the telescopic column 63 to move left and right. The drive end of the bidirectional cylinder 62 is fixedly connected to the telescopic column 63, and the telescopic column 63 slides externally. Connected inside the support plate 61, the telescopic column 63 can move along the inside of the support plate 61 under the drive of the bidirectional cylinder 62, thereby driving the fixed block 64 to move synchronously. The right end of the telescopic column 63 is fixedly connected to the fixed block 64, which can transmit the movement of the telescopic column 63 to the connecting rod 651. The right end of the fixed block 64 is provided with a moving component 65, which can provide power for the position adjustment of the auxiliary plate 655, thereby realizing the position correction of the bearing plate 56. The moving component 65 includes the connecting rod 651, which is L-shaped. The L-shaped design facilitates the connection between the fixed block 64 and the connecting column 653. The left end of the connecting rod 651 is fixedly connected to the right end of the fixed block 64. A fixing block 652 is rotatably connected to the top of connecting rod 3 651. The left end of fixing block 652 is fixedly connected to the right end of support frame 1. Fixing block 652 serves as the pivot point for the rotation of connecting rod 3 651, ensuring stable rotation of connecting rod 3 651. A connecting column 653 is fixedly connected to the top of connecting rod 3 651. Connecting column 653 can transmit the movement of connecting rod 3 651 to fixing block 3 654, thereby driving auxiliary plate 655 to move synchronously. Fixing block 3 654 is fixedly connected to the left end of connecting column 653. The fixing block 654 is used to connect the connecting column 653 and the auxiliary plate 655. The auxiliary plate 655 is fixedly connected to the left end of the fixing block 654. The movement of the fixing block 654 can drive the auxiliary plate 655 to move synchronously, ensuring that the auxiliary plate 655 can smoothly push the carrier plate 56. The bottom end of the auxiliary plate 655 is slidably connected to the top end of the conveyor belt 55. Through the sliding connection, it can contact the offset carrier plate 56 and push it back to the designated area in the center of the conveyor belt 55, so that the carrier plate 56 can stably enter the scanning area of the scanner 3.
[0014] Specifically, the bidirectional cylinder 62 is activated, which drives the telescopic column 63, causing the fixed block 64 to move. The fixed block 64 then moves the connecting rod 651 to the right, causing the connecting rod 651 to rotate around the fixed block 652 as the axis. This pushes the connecting column 653, causing the auxiliary plate 655 to move to the right, thus pushing the offset bearing plate 56 back to the designated area in the center of the conveyor belt 55, reducing the problems of missed defects and misjudged good products caused by positional deviation.
[0015] Reference Figure 1 , Figure 2 and Figure 4 The cleaning mechanism 7 includes a driven column 71, which rotates synchronously with the fixed column 53 driven by the motor 52, which in turn drives the rotating shaft 54. An arc-shaped groove is formed on the outside of the driven column 71, providing a guide path for the sliding of the connecting rod 72, allowing the connecting rod 72 to reciprocate as the driven column 71 rotates. The driven column 71 is rotatably connected to the right end of the support frame 1, which provides rotational support for the driven column 71, preventing it from shifting during rotation. The top of the driven column 71 is slidably connected to the connecting rod 72, which slides within the arc-shaped groove on the outside of the driven column 71, thereby causing the support rod 73 to move linearly. The top of the connecting rod 72 is fixedly connected to... A support rod 73 is provided, which can slide left and right under the drive of the connecting rod 72, so that the brush 74 can clean the surface of the carrier plate 56. The external part of the support rod 73 is slidably connected to the inside of the fixing plate 75. The fixing plate 75 provides guidance and limit for the left and right sliding of the support rod 73, preventing the support rod 73 from shaking or deviating during the sliding process. The bottom end of the support rod 73 is fixedly connected to the brush 74, which can clean the dust and hard particles on the surface of the carrier plate 56, avoiding dust accumulation that affects the detection results of the scanner 3. The front end of the support frame 1 is fixedly connected to the fixing plate 75. The fixing plate 75 provides a sliding base for the support rod 73 through the fixed connection with the support frame 1, ensuring the cleaning effect.
[0016] Specifically, when the carrier plate 56 reaches the top of the conveyor belt 55, the motor 52 drives the fixed column 53 to rotate the rotating shaft 54, which in turn drives the driven column 71 to rotate. The rotation of the driven column 71 causes the connecting rod 72 to slide in its external arc groove, which in turn drives the support rod 73 to slide left and right, so that the brush 74 slides outside the carrier plate 56, thereby cleaning the dust and hard particles on the surface of the carrier plate 56. This reduces the situation where the scanner 3 misjudges good products as defective products when scanning the carrier plate 56 due to dust accumulation, thus improving the accuracy of detection.
[0017] The implementation principle of this application embodiment is as follows: When the operator uses the chip sorting device with integrated photoelectric detection, the motor 52 is started. The motor 52 drives the fixed column 53 to make the rotating shaft 54 drive the conveyor belt 55 to rotate. At this time, the carrier tray 56 can be placed at the top of the conveyor belt 55. The scanner 3 scans and filters out unqualified chips and marks them. The position data of the unqualified chips is transmitted to the control machine 42. When the carrier tray 56 is transported to the designated position, the control machine 42 drives the telescopic rod 43 to move the connecting rod 44, which in turn causes the connecting rod 45 to move the adsorption tray 46, adsorbing the unqualified chips on the surface of the carrier tray 56 and placing them inside the collection box 47 for subsequent collection and processing. The qualified chips are transported to the next process with the conveyor belt 55.
[0018] Before the carrier tray 56 is conveyed to the scanner 3, the bidirectional cylinder 62 is activated. The bidirectional cylinder 62 drives the telescopic column 63 to move the first fixed block 64. The movement of the first fixed block 64 causes the third connecting rod 651 to move to the right, which in turn causes the third connecting rod 651 to rotate around the second fixed block 652 as the axis. This pushes the connecting column 653 to move the auxiliary plate 655 to the right. When the auxiliary plate 655 moves to the designated position, it contacts the carrier tray 56, pushing the offset carrier tray 56 back to the designated area in the center of the conveyor belt 55. This allows the carrier tray 56 to stably enter the scanning area of the scanner 3, reducing the problem of missed defects and misjudged good products caused by positional deviation, thereby ensuring the detection and sorting effect.
[0019] When the carrier plate 56 enters the top of the conveyor belt 55, the fixed column 53 driven by the motor 52 drives the rotating shaft 54 to rotate, which in turn drives the driven column 71 to rotate. The rotation of the driven column 71 causes the connecting rod 72 to slide in the arc groove outside the driven column 71. The sliding of the driven column 71 in the arc groove drives the support rod 73 to slide left and right, which in turn causes the brush 74 to slide outside the carrier plate 56. Through the reciprocating sliding of the brush 74, the dust and hard particles on the surface of the carrier plate 56 are cleaned, reducing the situation where the scanner 3 and the carrier plate 56 mistakenly identify good products as defective products due to dust accumulation, thereby improving the accuracy of detection.
[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
