The placement plate 31 is a cuboid structure and is located at the center of the top of the workbench 1. Several bases 32 are cuboid structures and are arranged opposite each other on the left and right sides of the placement plate 31, with the height of the bases 32 being the same as the height of the placement plate 31. The clamping box 33 is located on the top of each base 32. The clamping groove 34 is located inside each clamping box 33. Several main plates 35 are arranged opposite each other in the clamping groove 34 and all extend toward the placement plate 31. The adjusting plate 36 is located at the end of each main plate 35 facing the placement plate 31, and each pair of adjacent adjusting plates 36 extends toward the front and rear ends of the clamping box 33. The clamping plate 37 is located at the end of each adjusting plate 36 facing the placement plate 31.

[0028] Specifically, the main board 35 is provided with a limiting groove 351, a limiting post 352, a rod groove 353, a bidirectional lead screw 354, and a motor 355. The limiting groove 351 is provided through the left and right halves of the part of each main board 35 located inside the clamping box 33. The limiting post 352 is provided between two main boards 35 located inside the same clamping box 33 and is located inside the limiting groove 351. The rod groove 353 is provided between two limiting grooves 351 on each main board 35. The bidirectional lead screw 354 is provided between two adjacent limiting posts 352 and is located inside the rod groove 353. The motor 355 is provided at the front end of each bidirectional lead screw 354 and is located at the front end of the clamping box 33.

[0029] The adjustable plate 36 is provided with a block slide 361, a column slide 362, a locking plate 363 and several slots 364. The block slide 361 is a cuboid structure and is located at the top and bottom center of the side of the adjustable plate 36 facing the placement plate 31. The column slide 362 is located on the top and bottom sides of the block slide 361. The locking plate 363 is a cuboid structure and is located at the end of the adjustable plate 36 away from the placement plate 31. The several slots 364 are evenly arranged inside the locking plate 363, corresponding to the position of each column slide 362.

[0030] The clamping plate 37 is provided with a slider 371, a column slide groove 372, a fixed plate 373, a movable plate 374, a return spring 375, a pull post 376, and an insert post 377 inside and outside. The slider 371 is located at the end of each clamping plate 37 facing the adjusting plate 36 and inside the block slide groove 361. The column slide groove 372 is circular and is located on the side wall of the clamping plate 37 at the upper and lower ends of the block slide groove 361. The fixed plate 373 is located inside the clamping plate 37 away from the adjusting plate 36. At one end, the movable plate 374 is located on the side of the fixed plate 373 facing the adjusting plate 36. The return spring 375 is located between the fixed plate 373 and the movable plate 374. One end of the pull post 376 is located at the end of the movable plate 374 facing the fixed plate 373, and the other end passes through the interior of the return spring 375, the outer wall of the fixed plate 373 and the clamping plate 37 and extends outward. The insertion post 377 is located at the end of the movable plate 374 facing the adjusting plate 36, corresponding to the position of each post slide groove 372.

[0031] This solution uses a bidirectional lead screw 354 to control the two motherboards 35 to close together, thereby moving the adjusting plate 36 and the clamping plate 37 towards the center to clamp the chip. This process is driven by a motor 355 and requires no manual intervention, completing most of the clamping work. Additionally, a pull post 376 can be used to move the clamping plate 37 along the adjusting plate 36, increasing the upper limit of the clamping distance and achieving a capacity expansion function. While expanding capacity, each slot 364 can further subdivide the distance between the clamping plates 37, and in conjunction with the operation of the bidirectional lead screw 354, this allows for better clamping of larger chips, avoiding situations where the chip cannot be clamped due to a large expansion width.

[0032] Working principle: During operation, the motor 355 is controlled by an external controller. The motor 355 controls the bidirectional lead screw 354 to rotate, which drives the main board 35 to move towards the center. This, in turn, drives the adjusting plate 36 and the clamping plate 37 to move and clamp the chip. If the chip is large, the pull post 376 can be pulled out and the insertion post 377 can be pulled out of the slot 364 through the movable plate 374. Then, the clamping plate 37 is adjusted to a suitable position and the pull post 376 is released, so that the insertion post 377 is inserted into the corresponding slot 364 to complete the further adjustment of the clamping distance.

[0033] This utility model comprises: 1-workbench; 2-several supporting legs; 3-positioning mechanism; 31-placement plate; 32-several bases; 33-clamping box; 34-clamping groove; 35-several main plates; 351-limiting groove; 352-limiting post; 353-rod groove; 354-double-acting lead screw; 355-motor; 36-adjusting plate; 361-block slide groove; 362-column slide groove one; 363-clamping plate; 364-several slots; 37-clamping plate; 371-slider; 372-column slide groove two; 373- Fixed plate; 374-movable plate; 375-reset spring; 376-pull post; 377-insertion post.
