Description

Technical Field

[0001] The present invention belongs to the technical field of integrated circuit chip manufacturing, and in particular relates to an integrated circuit chip detection tool. Background Art

[0002] In the manufacturing process of integrated circuit chips, efficient and accurate chip testing is a key step in ensuring product quality. As the application areas of integrated circuit chips continue to expand, the market demand for chips continues to grow, which places higher demands on chip testing efficiency. To meet the needs of efficient detection, some inspection tooling has adopted a design concept of setting up multiple inspection cameras corresponding to multiple columns of chips on the tray, so as to achieve synchronous detection of multiple columns of chips and greatly improve detection efficiency. However, this detection method has extremely high requirements for the accuracy of the tray loading position. At present, robots are often used to assist in loading, but in actual operation, due to factors such as the precision limitations of the mechanical structure, deviations in the control algorithm, and interference from the external environment, the loading position is not accurate. This may result in a situation where the camera cannot accurately correspond to multiple columns of chips, making some chips unable to be effectively detected, reducing the accuracy and reliability of the detection. Furthermore, during the inspection process using a conveyor belt, the friction between the belt and the pallet is limited and can fluctuate dynamically. When the pallet is heavy or experiences vibration during transport, the belt struggles to provide stable and smooth transport. The pallet is prone to misalignment and jamming during transport, which not only affects the continuity of chip inspection but also reduces detection accuracy and efficiency.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] See Figure 1 、 Figure 3 、 Figure 4 and Figure 10 , this embodiment provides an integrated circuit chip testing tool, comprising: Conveyor belt 2; Tray 1, placed on the conveyor belt, used to hold chips; Two sets of transmission belts 3 are respectively arranged to rotate above the two sides of the conveyor belt 2, and the transmission belts 3 and the conveyor belt 2 have the same linear speed; A plurality of pressing plates 4 are arranged at intervals on the transmission belt 3; The adjusting plate 5 is provided with a longitudinal adjustment groove. The vertical distance between the pressing plate 4 and the conveyor belt 2 is adjustable under the guidance of the longitudinal adjustment groove. When the vertical distance between the pressing plate 4 and the conveyor belt 2 is reduced, the pressing plate 4 is used to press the pallet 1 on the conveyor belt 2. Specifically, when the pressing plate 4 is guided down by the longitudinal adjustment groove, the longitudinal distance between the pressing plate 4 and the conveyor belt 2 is reduced, and the pressing plate 4 is pressed on the pallet 1. The pallet 1 is stably conveyed by the cooperation of the pressing plate 4 and the conveyor belt 2; when the pressing plate 4 is guided up by the longitudinal adjustment groove, the longitudinal distance between the pressing plate 4 and the conveyor belt 2 is increased, and the pressing plate 4 leaves the pallet 1, releasing the pressure on the pallet 1, thereby facilitating the loading and unloading of the pallet 1; The loading platform 6 is provided at the loading end of the conveyor belt 2; A pair of alignment plates 7 are symmetrically arranged on both sides of the loading platform 6 to limit its position perpendicular to the conveying direction of the pallet 1. The two sets of alignment plates 7 are configured to adjust the position of the pallet 1 on the loading platform 6 from both sides of the loading platform 6. The two sets of alignment plates 7 cooperate to adjust the pallet 1 on the loading platform 6 from the manipulator to the center of the loading platform 6 to correspond to the positions of the conveyor belt 2 and the pressing plate 4, thereby ensuring the accuracy of the loading position of the pallet 1; The loading belt 8 is rotatably disposed on the positioning plate 7 and is used to load the tray 1 on the loading platform 6 onto the conveyor belt 2.

[0020] During operation, the robot places the tray 1 containing the chips on the loading platform 6. Two sets of positioning plates 7 approach and push the tray 1 from both sides, adjusting the tray 1 to the middle position of the loading platform 6 to complete the loading position adjustment of the tray 1. The loading belt 8 and the conveyor belt 2 cooperate to load the adjusted tray 1 onto the conveyor belt 2. The pressing plate 4 is pressed on the tray 1 by the guidance control of the longitudinal adjustment groove on the adjustment plate 5. The pressing plate 4 is driven by the transmission action of the conveyor belt 3 to move synchronously with the conveyor belt 2. The pressing plate 4 and the conveyor belt 2 cooperate to ensure the stable transportation of the tray 1. During the stable transportation of the tray 1, the appearance inspection of the chips placed in the tray 1 is completed.

[0021] Specifically, see Figure 6 and Figure 7 In this embodiment, the longitudinal adjustment groove includes a pressing groove 9, a transition groove 10 and a lifting groove 11. The pressing groove 9 and the lifting groove 11 are located on the opposite side walls of the adjustment plate 5. The side of the adjustment plate 5 with the pressing groove 9 is located above the conveyor belt 2. The transition groove 10 and the pressing groove 9 are arranged on the same side wall of the adjustment plate 5. There are two groups of transition grooves 10. The two ends of the pressing groove 9 are respectively connected to one end of the two groups of transition grooves 10, and the two ends of the lifting groove 11 are respectively connected to the other end of the two groups of transition grooves 10. The height position of the lifting groove 11 is higher than the height position of the pressing groove 9, and the transition groove 10 is an inclined groove.

[0022] Specifically, see Figure 6-Figure 9 In this embodiment, a connecting plate 12 is provided on the transmission belt 3, and a transmission block 13 is connected to the connecting plate 12. A slide rod 14 is provided on the transmission block 13 for sliding through. A mounting block 15 is provided on the upper end of the slide rod 14. A sliding column 16 is provided on the mounting block 15. The sliding column 16 is engaged and slidably arranged in the longitudinal adjustment groove. A group of transition grooves 10 is used to guide the sliding column 16 to move from the pressing groove 9 to the lifting groove 11, and another group of transition grooves 10 is used to guide the sliding column 16 to move from the lifting groove 11 to the pressing groove 9. The pressing plate 4 is connected to the lower end of the slide rod 14. A return spring 17 is provided between the mounting block 15 and the transmission block 13, and the return spring 17 is sleeved on the slide rod 14.

[0023] During operation, the transmission belt 3 drives the transmission block 13 through the connecting plate 12 to move at the same linear speed as the conveyor belt 2. The transmission block 13 drives the sliding column 16 and the pressing plate 4 to move synchronously through the slide rod 14. When the sliding column 16 enters the pressing groove 9 from the lifting groove 11 along the transition groove 10, the pressing plate 4 descends and presses on the pallet 1, and in conjunction with the conveyor belt 2, the pallet 1 is stably conveyed. When the sliding column 16 enters the lifting groove 11 from the pressing groove 9 along the transition groove 10, the pressing plate 4 rises, releasing the pressure on the pallet 1, thus meeting the unloading requirements of the pallet 1. The provision of the return spring 17 also improves the smoothness of the movement of the sliding column 16 from the pressing groove 9 to the lifting groove 11.

[0024] Specifically, see Figure 8 and Figure 9 In this embodiment, the adjustment plate 5 is a cavity structure, the longitudinal adjustment groove is set through the side wall of the adjustment plate 5, and the sliding column 16 is located in the cavity of the adjustment plate 5 and has a limiting protrusion 18 on one end.

[0025] Specifically, see Figure 6 In this embodiment, a load-bearing column 19 is fixedly provided on the lower surface of the adjustment plate 5, and a load-bearing plate 20 is installed at the lower end of the load-bearing column 19. The transmission belt 3 is rotated on the load-bearing plate 20 through a rotating shaft, and a ball 21 is provided on the lower surface of the transmission block 13. The transmission block 13 rolls on the load-bearing plate 20 through the ball 21. The setting of the ball 21 improves the smoothness of the movement of the transmission block 13 along with the transmission belt 3.

[0026] Specifically, see Figure 11 In this embodiment, mounting brackets 22 are symmetrically provided on both sides of the loading platform 6, and a pushing cylinder 23 is fixed on the mounting bracket 22. The positioning plate 7 is connected to the free end of the pushing cylinder 23. Under the action of the pushing cylinder 23, the positioning plate 7 is pushed close to the pallet 1 from both sides, and the pallet 1 is pushed to the middle position of the loading platform 6.

[0027] It should be noted that a guide telescopic rod is provided between the mounting frame 22 and the alignment plate 7. The setting of the guide telescopic rod can ensure the driving stability of the pushing cylinder 23 on the alignment plate 7. The guide telescopic rod includes a guide sleeve and a guide slide 14. The guide sleeve is fixed on the mounting frame 22, and the guide slide 14 is slidably provided in the guide sleeve, and the guide slide 14 is connected to the alignment plate 7.

[0028] Specifically, see Figure 11 In this embodiment, a roller groove 24 is opened on the loading platform 6, and a roller 25 is rolled in the roller groove 24. The setting of the roller 25 improves the smoothness of the positioning plate 7 pushing the pallet 1 to move on the loading platform 6. A lifting cylinder 26 is provided under the loading platform 6. When the loading belt 8 drives the pallet 1 to load the conveyor belt 2, the loading platform 6 is driven down by the setting of the lifting cylinder 26 to prevent the roller 25 from affecting the loading of the pallet 1.

[0029] Specifically, see Figure 3 In this embodiment, side baffles 27 are provided on both sides of the conveyor belt 2, and conveying grooves 28 are provided on the side baffles 27 and the positioning plate 7. Conveying rollers 29 are rotatably provided in the conveying grooves 28. The setting of the conveying rollers 29 can guide and limit the position of the pallet 1 and improve the smoothness of the loading and conveying of the pallet 1.

[0030] Specifically, see Figure 2-Figure 5 In this embodiment, an integrated circuit chip inspection tool further includes an inspection mechanism 30, which includes a support frame, an inspection camera 31, a picking component 32, a transfer belt 33 and a controller 34. The inspection camera 31 is arranged on the support frame. There are multiple groups of inspection cameras 31. The number of groups of inspection cameras 31 corresponds to the number of columns of chips on the tray 1. Each group of inspection cameras 31 is responsible for inspecting the appearance of a column of chips. The inspection camera 31 is arranged near the transition groove 10 moving from the pressing groove 9 to the lifting groove 11. The pressing plate 4 moves along the transition groove 10. When the aqueduct 10 slides to the detection camera 31, its height is higher than the detection camera 31, so as to prevent the detection camera 31 from affecting the lifting of the pressing plate 4 from low to high along with the transmission belt 3 and the movement after the lifting is completed. The selection component 32 is arranged on the support frame. The selection component 32 is used to select chips with unqualified appearance. A chip placement groove 35 is provided on the transfer belt 33. The transfer belt 33 is used to transfer unqualified chips. The controller 34 is arranged on the support frame. The detection camera 31, the selection component 32, and the transfer belt 33 are all electrically connected to the controller 34.

[0031] It should be noted that the controller 34 controlling the detection camera 31 for detection, the selection component 32 for selection, and the transfer belt 33 for transfer are all prior art, so the control system thereof will not be described in detail. The selection component 32 may adopt the following structure: The picking assembly 32 includes a driving screw, a driving slide 14, a driving block and a driving motor. The driving screw is rotatably mounted on a support frame, the driving motor is fixedly mounted on the support frame, one end of the driving screw is fixedly connected to the output end of the driving motor, the driving slide 14 is fixedly mounted on the support frame, the driving block is connected to the driving screw by a thread, and is slidably mounted on the driving slide 14. A negative pressure pump and a telescopic rod are installed on the driving block, and a suction cup is provided at the free end of the telescopic rod, which is connected to the negative pressure pump via a pipe. When the detection camera 31 detects an unqualified chip, the driving screw and the driving slide 14 cooperate to drive the driving block to move to the position of the unqualified chip under the driving action of the driving motor. The unqualified chip in the tray 1 is sucked out by the telescopic action of the telescopic rod and the cooperation of the negative pressure pump and the suction cup, and is transferred to the transfer belt 33 for transportation.

[0032] And as a preferred embodiment, two groups of the selection components 32 and the transfer belts 33 are provided to solve the problem of two unqualified chips appearing at the same time.

[0033] The working principle of the integrated circuit chip detection tool provided in this embodiment is as follows: (1) The robot places the tray 1 loaded with chips on the loading platform 6, and drives the positioning plate 7 to move by pushing the cylinder 23. The two sets of positioning plates 7 cooperate to adjust the tray 1 to the middle position of the loading platform 6. In the process of pushing the tray 1 to move, the setting of the roller 25 improves the smoothness of the position adjustment of the tray 1. After the adjustment is completed, the two ends of the tray 1 are exactly located on the two sets of loading belts 8; (2) The lifting cylinder 26 drives the loading platform 6 to descend, and the pallet 1 is loaded with the cooperation of the two sets of loading belts 8. With the cooperation of the conveyor rollers 29, the pallet 1 is stably loaded onto the conveyor belt 2; (3) When the pallet 1 moves along the conveyor belt 2, the pressing plate 4 is controlled to descend and press on the pallet 1 under the adjustment and guidance of the longitudinal adjustment groove. The pressing plate 4 cooperates with the conveyor belt 2 to stably convey the pallet 1, ensuring that the pallet 1 is stably, efficiently and accurately conveyed to the bottom of the CCD camera; (4) Under the action of the controller 34, the picking component 32 is controlled to transfer the chips with unqualified appearance detected by the CCD camera to the transfer belt for transfer.
