[0030] Please see Figure 1-8 In this embodiment of the utility model, a chip casing pressing fixture includes a pressing mechanism 1, on which a pressing fixture 2 is mounted;

[0031] The crimping fixture 2 includes an upper pressing block 21, the upper end of which is fixedly connected to the pressing head 110; the lower end of the upper pressing block 21 is provided with symmetrical limiting grooves 28 on its inner side, and each limiting groove 28 is provided with symmetrical mounting holes on its inner side. The symmetrically arranged mounting holes are fixedly connected to the lower end spring rod 22. The spring rod 22 is symmetrically arranged on the upper surface of the pin pressing block 23. The pin pressing block 23 is also symmetrically arranged and is slidably connected to the upper end and the symmetrically arranged limiting grooves 28.

[0032] The upper pressure block 21 has stepped bolts 24 symmetrically arranged on its inner side. The bottom of the stepped bolts 24 is threadedly connected to the lower pressure block 25. The lower pressure block 25 has symmetrically arranged sliding grooves 26 on its inner side. The symmetrically arranged sliding grooves 26 are slidably connected to the upper pin pressure block 23 symmetrically arranged at its upper end. The lower surface of the lower pressure block 25 has symmetrically arranged positioning blocks 27.

[0033] By adopting the above technical solution, the positioning block 27 is used to position the chip 16. Combined with the structural design of the pin pressing block 23 and the lower pressing block 25, the chip 16 can be positioned accurately on the housing 15, improving the accuracy of the pressing and ensuring the electrical and mechanical performance of the product.

[0034] In this embodiment, the lower end of the chip 16 is connected to the housing 15, the bottom of the housing 15 is connected to the pressure base 14, the bottom of the pressure base 14 is slidably connected to the pressure groove 12, and the center position of the bottom of the pressure base 14 is fixedly connected to the upper end of the spring 13.

[0035] The spring 13 is located inside the pressure groove 12, and the lower end of the spring 13 is connected to the pressure groove 12. The pressure groove 12 is located inside the base plate 11.

[0036] The upper end of the base plate 11 is fixedly connected to the fixing frame 17 by bolts. The upper side of the fixing frame 17 is provided with an electric cylinder seat 18. A telescopic electric cylinder 19 is fixedly installed on the electric cylinder seat 18. A pressure head 110 is installed at the end of the telescopic electric cylinder 19. The lower inner side of the pressure head 110 is fixedly connected to the upper pressure block 21.

[0037] By adopting the above technical solution, the spring rod 22 and the bottom spring 13 of the pressure seat 14 can be set so that the pressure during the crimping process can be applied evenly to the chip 16, avoiding damage to the chip 16 or poor connection due to uneven pressure, and improving the product yield.

[0038] In this embodiment, the symmetrically arranged positioning blocks 27 and symmetrically arranged pin pressing blocks 23 are alternately arranged along the lower periphery of the lower pressing block 25.

[0039] The bottom of the symmetrically arranged positioning block 27, the symmetrically arranged pin pressing block 23, and the lower pressing block 25 are connected to the upper end of the chip 16.

This structural design ensures the overall stability of the fixture during the pressing process, reduces shaking and displacement, and improves the pressing quality and production efficiency.

[0041] The working principle of this utility model is as follows: After the telescopic electric cylinder 19 is started, the pressure head 110 at its end drives the upper pressure block 21 fixedly connected to it to move downward. When the pressing fixture 2 contacts the chip 16, the positioning block 27 first accurately positions the chip 16. The pin pressing block 23 and the lower pressing block 25 cooperate to evenly transmit the pressure to the chip 16, realizing the pressing of the chip 16 and the shell 15. During this process, the spring rod 22 plays the role of buffering and fine-tuning the pressure, making the pressure more uniform and stable. The spring 13 at the bottom of the pressing base 14 can provide a certain elastic buffer during pressing to avoid excessive pressure from damaging the chip 16 or the shell 15. At the same time, it assists the pressing base 14 to reset after pressing is completed. Positioning the chip 16 using the positioning block 27, combined with the structural design of the pin clamping block 23 and the lower clamping block 25, ensures the precise position of the chip 16 on the housing 15, improving the accuracy of crimping and guaranteeing the electrical and mechanical performance of the product. The spring rod 22 and the bottom spring 13 of the clamping base 14 ensure that the pressure is evenly applied to the chip 16 during the crimping process, avoiding damage to the chip 16 or poor connection due to uneven pressure, thus improving the product yield. The upper clamping block 21 and the lower clamping block 25 are connected by the stepped bolt 24, and the pin clamping block 23 is slidably connected to the limiting groove 28 and the sliding groove 26. This structural design ensures the overall stability of the fixture during the crimping process, reduces shaking and displacement, and improves the crimping quality and production efficiency.
