[0028] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0029] like Figure 1-6 As shown, a chip clamping fixture includes:

[0030] Base plate 1, with a clamping groove 15 provided on it;

[0031] The clamping unit 3 is disposed on the base plate 1, and the clamping unit 3 includes a clamping frame 31 and a clamping part 311 disposed on the clamping frame 31. The clamping part 311 cooperates with the clamping groove 15, and a first clamping member 32 and a second clamping member 33 are respectively disposed on the clamping part 311.

[0032] The second clamping member 33 includes a spring 333, a support frame 334, and a pressing block 332 slidably connected within the support frame 334. The spring 333 is disposed within the support frame 334 and pushes the pressing block 332 to slide toward the first clamping member 32.

[0033] Specifically, a placement groove (such as) is provided at the symmetrical center of the base plate 1. Figure 2 As shown, the base plate 1 can easily clamp the chip onto the clamping bracket 31 at the center. During the chip clamping process, the chip slides along the clamping groove 15 into the clamping part 311, and one end of the chip is stuck into the first clamping member 32. At this time, under the elastic action of the spring 333, the pressing block 332 is pushed close to the first clamping member 32 to clamp the chip, which improves the clamping efficiency and also enables the base plate 1 to adapt to chips of different specifications.

[0034] As a further embodiment of this utility model, the extrusion block 332 is provided with an arc-shaped groove 331, and one side of the arc-shaped groove 331 is provided with an extended inclined surface, so that the chip can be inserted into the arc-shaped groove 331 along the inclined surface during the clamping process, thereby improving the efficiency of the chip and reducing damage to the chip.

[0035] As a further embodiment of this utility model, a screw 16 is provided on the base plate 1, and sliders 17 are arranged in a linear array on the screw 16. Push blocks 18 are provided on the sliders 17. Push blocks 18 slide on the clamping frame 31. An extension block 335 that cooperates with the push block 18 is engaged on the support frame 334. A cover plate 13 is provided on the base plate 1. Opening the cover plate 13 allows maintenance of the screw 16. Rotating the screw 16 controls the push block 18 on the slider 17 to slide on the clamping frame 31. The extension block 335 pushes the support frame 334 to slide on the clamping part 311, so that the squeezing block 332 is close to the first clamping member 32, which improves the pre-compression effect of the spring 333, thereby improving the clamping force on the chip.

[0036] As a further embodiment provided by this utility model, the first clamping member 32 includes a support block 323, a locking block 322 is provided on the support block 323, and a locking groove is provided on the locking block 322. The locking groove is parallel to the arc groove 331 of the pressing block 332. When the pressing block 332 approaches the first clamping part 311, the two ends of the chip are respectively locked into the locking groove and the arc groove 331.

[0037] As a further embodiment of this utility model, a limiting block 321 is engaged in the card slot to limit the sliding distance of the chip on the card block 322. The position of the limiting block 321 is adjusted according to the chip width to improve the clamping effect on the chip.

[0038] As a further embodiment of this utility model, a groove 2 is provided on the base plate 1, and a motor 41 is provided in the groove 2. A second pulley 43 is provided at the output end of the motor 41, and a first pulley 34 is provided at one end of the clamping frame 31. A synchronous belt 42 is provided between the first pulley 34 and the second pulley 43. The second pulley 43 is controlled to rotate by the motor 41, and the first pulley 34 is rotated by the second pulley 43 through the synchronous belt 42, which controls the rotation of the clamping frame 31, so that the chip can be processed at multiple angles, improving the adaptability of the chip.

[0039] As a further embodiment of this utility model, the clamping groove 15 is provided with an arc-shaped portion 14. During the chip clamping process, the chip will be inserted into the first clamping member 32 along the arc-shaped portion 14. The arc-shaped surface reduces the phenomenon of chip wear during the clamping process.

[0040] As a further embodiment provided by this utility model, the number of clamping slots 15 and clamping parts 311 is the same, and the length and width of the clamping parts 311 are smaller than the clamping slots 15. The more clamping slots 15 and clamping parts 311 there are, the more chips can be processed at one time. At least seven sets of clamping parts 311 and clamping slots 15 are provided.

[0041] As a further embodiment provided in this utility model, a positioning hole 11 is provided on the base plate 1. The positioning hole 11 plays a positioning role for the base plate 1, reducing the error in chip processing, and further improving the fixing effect of the base plate 1.

[0042] As a further embodiment of this utility model, support grooves 12 are provided on both sides of the base plate 1. The support grooves 12 facilitate manual holding of the base plate 1, and the base plate 1 can also be installed on the conveying equipment for processing through the support grooves 12.

[0043] Working principle: When clamping the chip, the chip is inserted one by one along the arc-shaped part 14 from above the clamping groove 15 into the clamping part 311, and one end of the chip is clamped into the slot on the first clamping part 311. At this time, under the elastic action of the spring 333, the pressing block 332 is pushed to contact the other end of the chip, giving a certain pre-pressure effect. Then, the screw 16 is rotated, and the slider 17 controls the push block 18 to slide on the clamping frame 31, so as to push the extension block 335 to slide on the clamping frame 31. Similarly, the support frame 334 is pushed to slide in the clamping part 311, thereby improving the pressing effect of the pressing block 332 on the chip. Furthermore, after processing one side of the chip, the screw 16 can be slightly rotated to reduce the clamping effect of the second clamping member 33 on the chip. At this time, the motor 41 runs, and the second pulley 43 controls the first pulley 34 to rotate through the synchronous belt 42, thereby flipping the chip for processing, thus adapting to the processing of chips of different specifications.

[0044] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0045] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
