Description

Technical Field

[0001] This utility model belongs to the field of chip technology, specifically relating to a limiting mechanism for semiconductor chip processing. Background Technology

[0002] A semiconductor chip is an electronic device made by etching and wiring on a semiconductor material, enabling it to perform specific functions. Common semiconductor materials include silicon, gallium arsenide, and germanium. Limiting mechanisms are required during the manufacturing process of semiconductor chips.

[0003] The prior art utility model patent with publication number CN 221486480 U discloses a limiting mechanism for semiconductor chip processing. The device, through the installation of the main body mechanism, enables the bidirectional screw to easily drive the movable block to move, thereby improving mobility. The bearing ensures stable rotation of the bidirectional screw and prevents it from shaking during operation, thereby improving stability. The movable block fixes the right clamping plate and the left clamping plate, which improves the limiting mechanism for semiconductor chip processing and effectively saves manpower.

[0004] However, in actual use, this device is inconvenient to flip and adjust the clamped chip. Generally, both the top and bottom sides of the chip need to be processed, requiring manual flipping and re-fixing of the chip. This results in high labor costs, long processing time, and low processing efficiency. Therefore, we need to upgrade and modify the existing technology. Utility Model Content

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1 - Figure 5As shown, this embodiment provides a limiting mechanism for semiconductor chip processing, including a baking device body 1. The device body 1 includes a worktable 2, and a mounting groove 5 is formed in the worktable 2. A bidirectional lead screw 6 is installed in the mounting groove 5. A first collar 7 and a second collar 8 are screwed onto the bidirectional lead screw 6, and one end of the bidirectional lead screw 6 is connected to a motor 9. A first connecting plate 11 is mounted on the first collar 7, and a second connecting plate 12 is mounted on the second collar 8. Rotating seats 1 are provided on the inner walls of both the first connecting plate 11 and the second connecting plate 12. 21. A rotating shaft 13 is rotatably installed inside the rotating seat 121. One end of the rotating shaft 13 is connected to a worm gear 14. A worm 15 meshes above the worm gear 14, and a connecting shaft 19 is provided at one end of the worm gear 14. A knob 17 is connected to one end of the worm 15. The connecting shaft 19 is connected to a clamp 1 20 and a clamp 21 respectively. A screw hole 22 is provided inside the clamp 1 20 and the clamp 21. A threaded post 23 is screwed into the screw hole 22. A preload plate 28 is connected below the threaded post 23, and a knob 24 is connected above the threaded post 23.

[0029] Preferably, a support leg 3 is connected to the bottom of the workbench 2, and multiple sets of support legs 3 are provided, with foot pads 4 fixedly installed under the support legs 3.

[0030] By setting up support legs 3, the workbench 2 can be supported. By setting up foot pads 4, the anti-slip properties and stability of support legs 3 are increased, ensuring the safety of the device during use.

[0031] Preferably, a fixing plate 10 is fixedly installed below the motor 9, and one end of the fixing plate 10 is welded and fixed to the worktable 2.

[0032] By setting the fixing plate 10, the stability of the motor 9 is increased, ensuring the safety of the motor 9 during use.

[0033] Preferably, a support frame 16 is sleeved on the worm gear 15, and one end of the support frame 16 is welded and fixed to the rotating seat 121;

[0034] By setting up the support frame 16, the safety of the worm gear 15 during use is ensured.

[0035] Preferably, anti-slip strips 18 are fixedly provided on the outer side walls of knob 17 and knob 24, and multiple sets of anti-slip strips 18 are provided.

[0036] By setting anti-slip strips 18, users are prevented from having difficulty turning knobs 17 and 24 due to slippage.

[0037] Preferably, a guide rod 26 is connected above the preload plate 28. Two sets of guide rods 26 are symmetrically arranged. Both clamp 1 20 and clamp 21 are provided with guide holes 25. The guide rods 26 are movably installed in the guide holes 25 and a limit plate 27 is fixedly connected above the guide rods 26.

[0038] By setting the guide rod 26, the direction of movement of the preload plate 28 can be guided. By setting the limiting plate 27, the guide rod 26 can be limited to prevent the guide rod 26 from disengaging from the guide hole 25 during movement.

[0039] Preferably, two sets of pre-compression plates 28 are symmetrically arranged, and an elastic pad 29 is connected below the pre-compression plate 28. The elastic pad 29 is fixedly connected to the pre-compression plate 28.

[0040] By setting the elastic pad 29, the stability and safety of the pre-pressure plate 28 are increased, and the pre-pressure plate 28 is prevented from being damaged or scratched during the pre-tightening process of the semiconductor.

[0041] The working principle and process of this utility model are as follows: During use, the control motor 9 drives the bidirectional lead screw 6 to rotate within the mounting groove 5. As the bidirectional lead screw 6 rotates, it causes the first collar 7 and the second collar 8 to move along it. The movement of the first collar 7 and the second collar 8 causes the connected connecting plates 11 and 12 to move. The movement of the first connecting plates 11 and 12 causes the clamps 20 and 21 to move closer together, placing the chip between them. Then, the user manually rotates the knob 24, causing the threaded post 23 to rotate downwards within the threaded hole 22. During this downward rotation, the pre-pressure plate 28 moves downwards until the elastic pad 29 of the pre-pressure plate 28 is in close contact with the chip. At this point, the chip is clamped and fixed, enabling clamping and limiting of the chip to be processed, facilitating user operation. Adjusting the device according to the chip size increases its practicality and convenience, expands its applicability, and ensures chip safety during processing. It prevents chip damage due to excessive clamping force. When the chip needs rotation adjustment during processing, the user manually turns knob 17. Knob 17 drives worm gear 15 to rotate within support frame 16. The rotation of worm gear 15 drives worm wheel 14, which in turn drives clamps 20 and 21. The rotation of clamps 20 and 21 causes the chip to rotate until it reaches the desired processing position. This allows for chip flipping and adjustment, facilitating multi-faceted chip processing and improving device efficiency. It also eliminates the need for frequent clamp changes, saving time.
