Description

Technical Field

[0001] This utility model relates to the field of single-crystal silicon wafer processing technology, and in particular to a fixed tooling for single-crystal silicon wafer processing. Background Technology

[0002] The silicon content in the wafer reaches 25.8%, providing an inexhaustible source for the production of monocrystalline silicon. Since silicon is one of the most abundant elements in the Earth's crust, its abundance is one of the reasons why silicon has become a primary material for photovoltaics, especially for products like solar cells destined for large-scale markets. However, existing silicon wafer processing methods often suffer from drawbacks due to a lack of fixed fixtures, leading to wafer breakage during cutting, increased production costs, and significant errors. Furthermore, during clamping, the central portion can sink under gravity, causing overall deformation and damaging the photovoltaic panel. Traditional equipment clamps the monocrystalline silicon wafer from both sides, resulting in the center of the wafer being unloaded and damaging it during processing. Therefore, we have redesigned a fixed fixture for processing monocrystalline silicon wafers. Utility Model Content

A clamping rotating plate 95 is fixedly connected to the top end of one side of the clamping threaded rod 93.

[0020] In the implementation scheme, by setting the drive threaded rod 4 inside the first adjustment limiting groove 2 and the second adjustment limiting groove 3 to rotate, the drive sliding block 5 can be driven to slide and adjust its position inside the first adjustment limiting groove 2 and the second adjustment limiting groove 3, thereby adjusting the distance between the two sides of the first monocrystalline silicon wafer fixing clamp 9. By rotating the first adjustment turntable 8, the position of the first height adjusting threaded rod 7 inside the first height adjusting frame 6 is adjusted, thereby adjusting the height of the first monocrystalline silicon wafer fixing clamp 9. Thus, the monocrystalline silicon wafer clamped and fixed by the first monocrystalline silicon wafer fixing clamp 9 can be adjusted to different heights. The adjustment can be made according to the height of the actual processing equipment. The clamping adjustment of the monocrystalline silicon wafer by the first monocrystalline silicon wafer fixing clamp 9 is achieved by rotating the clamping turntable 95 to adjust the position of the clamping threaded rod 93 inside the clamping disc 91, thereby adjusting the position height of the clamping limiting disc 94 inside the clamping groove 92 to achieve the clamping operation.

[0021] Example 2:

[0024] Working principle:

[0025] By rotating the drive threaded rod 4 inside the first adjustment limit groove 2 and the second adjustment limit groove 3, the drive sliding block 5 can be driven to slide and adjust its position inside the first adjustment limit groove 2 and the second adjustment limit groove 3, thereby adjusting the distance between the two first monocrystalline silicon wafer fixing clamps 9. By rotating the first adjustment turntable 8, the first height adjustment threaded rod 7 is adjusted to the top position inside the first height adjustment frame 6, thereby adjusting the height of the first monocrystalline silicon wafer fixing clamp 9. Thus, the monocrystalline silicon wafers clamped and fixed by the first monocrystalline silicon wafer fixing clamp 9 can be adjusted to different heights. The adjustment can be made according to the height of the actual processing equipment. The clamping adjustment of the monocrystalline silicon wafers by the first monocrystalline silicon wafer fixing clamp 9 is achieved by rotating the clamping turntable 95 to adjust the position of the clamping threaded rod 93 inside the clamping disc 91, thereby adjusting the position height of the clamping limit disc 94 inside the clamping groove 92 to achieve the clamping operation.
