[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0026] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see the appendix Figure 1 - Appendix Figure 6This utility model discloses a pin trimming device for integrated circuit manufacturing, comprising a base 1, on which a first electric push rod 9 is mounted. The telescopic end of the first electric push rod 9 is connected to the side of a sliding plate 2. A first servo motor 3 is connected to the side of the base 1. Side support plates 8 are provided at both the front and rear ends of the base 1. A side pressure plate 5 is provided on the base 1. A screw 4 is provided at the front end of the base 1. The screw 4 is threadedly connected to the side pressure plate 5 and connected to the drive shaft of the first servo motor 3. The screw 4 is rotatably connected to the base 1. The threads at both ends of the screw 4 are in opposite directions. A second rotating plate 16 is rotatably connected to the inner side of the sliding plate 2. A connecting plate 19 is provided on the side of the second rotating plate 16. A first servo motor 3 is rotatably connected to the side of the second rotating plate 16. The second adjustment mechanism 17 is threadedly connected to the connecting plate 19. The side of the connecting plate 19 is connected to the trimming plate 10. In actual use, the device is placed on the base 1, the first servo motor 3 is started to drive the screw 4 to rotate, so that the two side pressure plates 5 move and clamp the side of the device through the side pressure plates 5 to fix the device. The second servo motor 11 is started to drive the first rotating plate 12 to rotate, so that the first rotating plate 12 rotates 180 degrees and moves the trimming plate 10 to the upper end. The first electric push rod 9 is started to pull the sliding plate 2 closer to the device. The device is squeezed by the "L"-shaped pins on the trimming plate 10, and the side support plate 8 supports the pins on the inside to perform the trimming work.

[0028] In Example 1, servo push rods 7 are connected to both the front and rear ends of the base 1. The telescopic ends of the servo push rods 7 are connected to the side support plate 8. By activating the servo push rods 7, the side support plate 8 can be moved, which can change the distance between the side support plate 8 and the upper side of the base 1. The side support plate 8 can support the "L"-shaped pin, which is convenient for subsequent trimming operations.

[0029] A first pressure sensor 6 is fixedly installed on the side of the side pressure plate 5. The first pressure sensor 6 involved in the device is a Spartacus SBT760F miniature pressure sensor. The first pressure sensor 6 is in contact with the side of the device. When the sensitive element on the first pressure sensor 6 is squeezed, the sensitive element will change its physical properties such as deformation, resistance change or charge generation due to pressure. Then, the conversion circuit converts these physical changes into measurable electrical signals (such as voltage and current), thereby realizing the quantitative detection of pressure. When the pressure exceeds the threshold, the first servo motor 3 stops running to avoid damage to the device caused by excessive pressure from the side pressure plate 5 on the side of the device.

[0030] In the second embodiment, the trimming plate 10 has a square plate structure. The other end of the trimming plate 10 is fixedly connected to the side of the first rotating plate 12. The side of the first rotating plate 12 is slidably connected to the upper trimming mechanism 13. Rollers are rotatably connected to both the upper trimming mechanism 13 and the lower trimming mechanism 14. The "I"-shaped pins on the device are pressed by the rollers rotatably connected to the upper trimming mechanism 13 and the lower trimming mechanism 14 to perform trimming work.

[0031] The lower end of the connecting rod 18 is fixedly connected to the lower trimming mechanism 14. The upper end of the lower trimming mechanism 14 is rotatably connected to the first adjustment mechanism 15. The upper end of the first adjustment mechanism 15 is threadedly connected to the upper trimming mechanism 13. By rotating the first adjustment mechanism 15, the distance between the upper trimming mechanism 13 and the lower trimming mechanism 14 can be changed.

[0032] The other end of the upper trimming mechanism 13 is fixedly connected to the side of the connecting plate 19. A connecting rod 18 is slidably connected to the upper trimming mechanism 13. The connecting rod 18 supports the lower trimming mechanism 14. By rotating the second adjustment mechanism 17, the second adjustment mechanism 17 rotates along the threaded hole opened on the connecting plate 19, causing the connecting plate 19 and the upper trimming mechanism 13 to slide. This can change the position of the upper trimming mechanism 13 and the lower trimming mechanism 14 so that they can adapt to the position of the pins on the device.

[0033] A second servo motor 11 is fixedly connected to the sliding plate 2. A first rotating plate 12 is provided on the inner side of the sliding plate 2. The transmission end of the second servo motor 11 is fixedly connected to the first rotating plate 12. When the second servo motor 11 is started, it drives the first rotating plate 12 to rotate, so that the first rotating plate 12 rotates 180 degrees. The trimming plate 10 can be used to trim the "L" shaped pin.

[0034] Working principle:

[0035] First, place the device on the base 1. Start the first servo motor 3 to drive the screw 4 to rotate along the threaded hole on the side pressure plate 5, so that the two side pressure plates 5 move and clamp and fix the side of the device. Start the second servo motor 11 to drive the first rotating plate 12 to rotate 180 degrees, so that the trimming plate 10 moves to the upper end. Start the first electric push rod 9 to pull the sliding plate 2 closer to the device. With the cooperation of the side support plate 8, the pins are supported on the inside. The trimming plate 10 squeezes the "L"-shaped pins on the device to realize the device trimming work, improve the adaptability of the device, and facilitate personnel use. The entire process is completed.
