Abstract
Description
Technical Field
[0001] This utility model relates to the field of semiconductor packaging technology, specifically to a Clip pickup device. Background Technology
[0002] In existing chip manufacturing processes, replacing wire bonding with clip packaging can improve production efficiency, reduce manufacturing costs, and solve problems such as cold solder joints and lead neck breakage that occur during wire bonding. In the clip packaging process, one step involves using a pick-up device to transfer the cut jumpers onto the pre-applied adhesive chip, which is then sent to subsequent processes for further handling.
[0003] In existing picking devices, using a suction cup to pick up and place the cut jumper wires is one of the most common methods. These devices are equipped with a drive mechanism to move and lift the suction cup at the very end, enabling precise picking and placing of the jumper wires. Examples of such technical solutions include those described in Chinese invention patent application number 202411462375.X (filed October 18, 2024) entitled "Copper Sheet Bonding Equipment and Assembly Method for Semiconductor Device Punching and Feeding," Chinese utility model patent application number 202220840116.6 (filed April 13, 2022) entitled "A Semiconductor Mounting Machine," and Chinese utility model patent application number 202021382135.6 (filed July 14, 2020) entitled "Automatic Jumper Wire Mounting Machine."
[0004] However, existing technologies, including the aforementioned solutions, generally suffer from the following drawbacks: In chip jumper layouts, multiple jumpers are typically arranged, and different jumpers are even layered vertically. In existing technologies, the driving device usually only has one set of pickup devices. This approach requires multiple pickup stations for jumper placement and pickup, or multiple round trips using a single pickup device to complete the process. This not only reduces work efficiency and extends the overall chip processing length, but also reduces reliability when the pickup device handles various jumpers. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a Clip picking device, which has two sets of picking components that work alternately on the surface of the translation module, and can alternately pick up and put down jumpers on the chip, thereby improving work efficiency and improving the reliability and accuracy of jumper picking and putting down.
[0006] The technical solution adopted by this utility model to solve its technical problem is: the Clip picking device includes an adsorption mechanism for picking up and putting down jumpers. The adsorption mechanism is arranged at the end of the driving device. The driving device includes a horizontally arranged translation module. Two sets of picking components that work alternately are arranged on the translation module. An adsorption mechanism is provided in each picking component.
[0007] Preferably, the pickup component includes a base, which is connected to the moving part of the translation module. A vertically arranged lifting module is provided on the end face of the base, and the adsorption mechanism is rotatably mounted on the moving part of the lifting module.

A rotary drive mechanism is provided on the surface of the lifting frame for connecting to the adsorption mechanism and driving the adsorption mechanism to rotate.
[0009] Preferably, the adsorption mechanism includes a rotating frame, with a lifting block unit that can be raised and lowered at the bottom of the rotating frame. The lifting block unit passes through the base plate of the rotating frame. An adsorption lifting cylinder for driving the lifting block unit to rise and fall is provided on the surface of the lifting block unit. A suction nozzle for adsorbing jumper wires is provided at the bottom of the lifting block unit. Both the adsorption lifting cylinder and the suction nozzle are connected to a valve box arranged on the surface of the base through pipelines.
[0010] Preferably, a rotating mounting frame is provided on the surface of the lifting frame, and the rotating drive mechanism includes a rotating motor arranged on the surface of the rotating mounting frame. The motor shaft of the rotating motor passes downward through the rotating mounting frame and the lifting frame and is connected to the adsorption mechanism.
[0011] Preferably, a rotation limiting mechanism for limiting the rotation angle of the rotary motor is provided in the rotating mounting frame; a lifting limiting mechanism for limiting the lifting position of the lifting frame is provided between the back plate and the lifting frame; and a translation limiting mechanism for limiting the translation position of the two sets of pickup components is also provided on the translation module.
[0012] Preferably, the lifting block unit includes a lifting block located on the upper part of the rotating frame and an adsorption block located on the lower part of the rotating frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In the technical solution of this application, two sets of picking components are arranged on the surface of the translation module to work alternately, which can alternately pick up and place jumpers on the chip, thereby improving work efficiency and improving the reliability and accuracy of jumper picking and placing.
[0015] In the technical solution of this application, when the rotation detection switch is triggered twice consecutively at the side opening of the rotation detection disk, it indicates that the rotation detection disk has rotated more than 360°, thus avoiding excessive rotation of the adsorption mechanism in the same direction, which could damage the pipeline used to transport gas.

[0025] Figures 1-7This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-7 The present invention will be further described below.
[0026] like Figures 1-2 As shown, a clip pickup device includes a main frame, which includes spaced-apart support columns 3 and a horizontal beam mounted on the upper surface of the support columns 3 at both ends. A translational linear module 1 is mounted on the surface of the horizontal beam, and a pickup component 2 is mounted on each of the two sliders in the translational linear module 1. The chip to be processed passes under the horizontal beam, and the pickup components 2 on both sides respectively place jumpers onto the surface of the chip, which is then sent to the subsequent process for further processing. By arranging two sets of pickup components 2 on the surface of the horizontal beam, the two sets of pickup components 2 alternately perform pickup actions, improving work efficiency.
[0027] Combination Figures 3-5 The pickup assembly 2 includes a base 18, and the slider in the translation linear module 1 is fixed to the bottom surface of the base 18. A valve box 4 is provided on the surface of the base 18, and a solenoid valve assembly is provided inside the valve box 4. An external air source is connected to the solenoid valve assembly inside the valve box 4 through a pipeline (not shown in the figure) and is connected to the pneumatic components of this Clip pickup device.
[0028] A back plate 5 is vertically fixed to the front end of the base 18. A lifting linear module 19 is vertically arranged on the surface of the back plate 5. A lifting frame 9 is set on the front side of the lifting linear module 19, and the slider of the lifting linear module 19 is installed on the back of the lifting frame 9. A lifting detection plate 16 is set on one side of the top of the lifting frame 9, and a lifting limit switch 17 is set on the upper part of the same side of the back plate 5. A translation detection plate 15 is set on one side of the bottom of the back plate 5, and two translation limit switches 30 are set on the front end face of the main frame. Each translation limit switch 30 corresponds to one of the two pickup components 2. Both the lifting limit switch 17 and the translation limit switch 30 are implemented using commercially available U-shaped photoelectric sensors. When the lifting detection plate 16 rises to the lifting limit switch 17, it triggers the lifting limit switch 17, and the lifting linear module 19 stops running. Similarly, after the translation detection plate 15 triggers the corresponding translation limit switch 30, the translation linear module 1 stops the corresponding pickup component 2 from running.
[0029] Two lifting return springs 14 are installed on the front end face inside the lifting frame 9. A support plate is horizontally set on the top of the back plate 5. The front end of the support plate extends forward to the top of the lifting frame 9. The other end of the two lifting return springs 14 extends upward and is hooked to the support plate.
[0030] A rotating mounting bracket 12 is installed on the front surface of the lifting frame 9. A rotary motor 6 is installed on the top of the rotating mounting bracket 12. The motor shaft of the rotary motor 6 passes downward through the top surface of the rotating mounting bracket 12 and enters the interior of the rotating mounting bracket 12. The rotary motor 6 is connected to a rotating shaft inside the rotating mounting bracket 12 via a coupling 7. The rotating shaft passes downward through the rotating mounting bracket 12 and the lifting frame 9 and is connected to the adsorption mechanism 10 located at the lower part of the lifting frame 9, driving the adsorption mechanism 10 to rotate. A rotating bearing 11 is also provided between the lifting frame 9 and the adsorption mechanism 10.
[0031] A rotation detection disk 8 is horizontally fixed at the bottom of the coupling 7. An opening is provided on one side of the rotation detection disk 8, and a rotation detection switch 13 is provided on one side of the rotating mounting bracket 12. The rotation detection disk 8 is rotatably located within the rotation detection switch 13. The rotation detection switch 13 also uses a U-shaped photoelectric sensor. When the rotation detection switch 13 is triggered twice consecutively at the opening on the side of the rotation detection disk 8, it indicates that the rotation detection disk 8 has rotated more than 360°, preventing excessive rotation of the adsorption mechanism 10 in the same direction, which could damage the pipeline used to transport gas.
[0032] like Figures 6-7 As shown, the adsorption mechanism 10 includes a rotating frame 20, which is a rectangular frame, with a rotating bearing 11 located at the top of the rotating frame 20. Two lifting blocks 24 are arranged side-by-side inside the rotating frame 20, and an adsorption lifting cylinder 21 is fixed to the surface of each of the two lifting blocks 24. The adsorption lifting cylinder 21 is a commercially available needle-type cylinder, and its air passage is connected to the valve box 4 mentioned above.
[0033] The body of the adsorption lifting cylinder 21 is fixed to the surface of the corresponding lifting block 24, and the piston rod of the adsorption lifting cylinder 21 passes through the lifting block 24 and is fixed to the surface of the base plate of the rotating frame 20. When the piston rod of the adsorption lifting cylinder 21 moves, since the bottom of the piston rod is fixed, it drives its body and the lifting block 24 to rise and fall within the rotating frame 20.
[0034] A guide shaft 25 is provided on both the front and rear sides of the adsorption lifting cylinder 21. One end of the guide shaft 25 is fixed to the base plate of the rotating frame 20, and the other end extends vertically through the lifting block 24 and is movably connected to the lifting block 24. A lifting shaft is also provided at both ends of each lifting block 24. The top of the lifting shaft is fixed to the bottom of the lifting block 24, and the lifting shaft extends downward through the base plate of the rotating frame 20 to the lower part of the rotating frame 20. At the lower part of the rotating frame 20, two adsorption blocks 27 are provided, each corresponding to a lifting block 24. The adsorption blocks 27 are fixed to the lifting shafts extending from the corresponding lifting blocks 24. Therefore, when the lifting blocks 24 are lifted and lowered within the rotating frame 20 by the adsorption lifting cylinder 21, the adsorption blocks 27 rise and fall synchronously at the bottom of the rotating frame 20. An adsorption spring 26 is also fitted outside each lifting shaft, which assists in resetting after lifting. A linear bearing 23 is also provided at the lifting connection of the lifting shaft.
[0035] A through hole is provided in the middle of the base plate of the rotating frame 20. Two telescopic air pipes 29 are arranged in the through hole. The upper part of the two telescopic air pipes 29 passes upward through the corresponding lifting block 24 and is connected to the air nozzle 22 provided on the surface of the lifting block 24. The air nozzle 22 is connected to the valve box 4 mentioned above through a pipeline. The two telescopic air pipes 29 extend through the through hole in the middle of the base plate of the rotating frame 20 to the bottom of the rotating frame 20 and pass through the corresponding adsorption block 27. A suction nozzle 28 is provided at the bottom of the adsorption block 27, and the bottom of the telescopic air pipe 29 is connected to the suction nozzle 28 at the bottom of the corresponding adsorption block 27.
[0036] The specific working process and working principle are as follows:
[0037] The chip to be processed passes under the crossbeam and stops when it reaches the pickup component 2. The translation linear module 1 controls one of the pickup components 2 to move to directly above the jumper. The lifting linear module 19 drives the lifting frame 9 to move downward, causing the adsorption mechanism 10 to descend directly above the jumper. High-pressure gas is output to the adsorption lifting cylinder 21 through the solenoid valve group in the valve box 4. The adsorption lifting cylinder 21 drives the adsorption block 27 to move down and contact the jumper. After contact, the jumper is adsorbed through the suction nozzle 28. The adsorption lifting cylinder 21 then actuates again, causing the jumper to rise.
[0038] The combined action of the translational linear module 1 and the lifting linear module 19 transfers the picked-up jumper wire to the surface of the chip, and then the suction lifting cylinder 21 transfers the jumper wire to the corresponding bonding position on the chip. Then, the suction at the nozzle 28 is released, releasing the jumper wire. The current pickup component 2 moves away under the combined action of the translational linear module 1 and the lifting linear module 19, while another pickup component 2 transfers another jumper wire to the chip surface according to the above actions.
[0039] Then the chip continues to be transferred to the next process. During the above-mentioned process of picking up and releasing the jumper, when rotation is required, the suction mechanism 10 is rotated by the rotary motor 6 so that the suction nozzle 28 can be aligned with the arrangement direction of the jumper.
[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
