Description

Technical Field

[0001] The present invention belongs to the field of support platforms, and specifically relates to a support platform for multi-angle cutting of crystalline silica. Background Art

[0002] Both crystalline silicon and amorphous silicon are semiconductor materials. Their characteristic is that the conductivity is between that of metals and insulators, and they are important materials for semiconductor manufacturing. The crystalline form of crystalline silicon is similar to substances such as quartz and graphite. Due to its high crystallinity, it has high electrical conductivity and photoelectric conversion efficiency. However, the manufacturing cost is relatively high, it is fragile and has a large volume. Crystalline silicon also includes regular single-crystalline silicon and irregular crystalline silica.

[0003] In the existing related patent, the "Device and Working Method for Clamping Single-Crystalline Silicon Claws" with the patent number CN202011525157.8 has the characteristics of "the designed clamping claw mechanism has high strength and stable reliability, and is used to clamp overweight and large-size single-crystalline silicon rods, which can solve the problem that the traditional lifting structure is difficult to carry overweight single-crystalline silicon. The clamping claw mechanism clamps the waist of the single-crystalline silicon rod for lifting, which helps to reduce the risk of neck fracture". However, it still has some deficiencies. Its clamping claw mechanism can clamp regular-shaped single-crystalline silicon well, and other existing technologies are also mostly good at clamping regular-shaped crystalline silicon. When facing crystalline silica with many grooves and depressions on its surface, it cannot effectively clamp the grooves and depressions, resulting in unstable clamping. Therefore, a support platform for multi-angle cutting of crystalline silica is proposed. Summary of the Invention

[0004] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Simplifications or omissions may be made in this part, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this part, the abstract, and the title. However, such simplifications or omissions cannot be used to limit the scope of the present invention.

[0005] In view of the following technical problems existing in the prior art: the clamping claw mechanism can clamp regular-shaped single-crystalline silicon well, and other existing technologies are also mostly good at clamping regular-shaped crystalline silicon.

[0024] The beneficial effects of a support platform for multi-angle cutting of crystalline silicon stone of the present invention: By using the abutting member, after the clamping assembly clamps the crystalline silicon stone, it contacts the outer side surface of the crystalline silicon stone, increasing the friction force between the abutting member and the clamping assembly, making it clamped more stably. Specifically, the spring plate presses the abutting plate and the spring plate, so that the contact mold can extend into the grooves and depressions on the outer side of the crystalline silicon stone, and the crystalline silicon stone can be clamped more stably;

[0025] The electromagnet generates a magnetic field to make the frames above and below the electromagnet approach each other, and the frames drive the two clamping arms to approach each other as well, clamping the crystalline silicon stone therein.

The connecting shaft 307 is rotatably connected to the frame 301;

[0043] The electromagnet 107 generates a magnetic field to make the upper and lower frames 301 of the electromagnet 107 approach each other, and the frame 301 also drives the two clamping arms 302 to approach each other, so that the silicon crystal stone therein is clamped.

[0044] The clamping assembly 300 further includes a retaining ring 303. The retaining ring 303 is sleeved on the connecting shaft 307, and the retaining ring 303 is located between the frame 301 and the clamping arm 302;

[0046] The clamping assembly 300 further includes a communication groove 308. A plurality of communication grooves 308 are formed on the clamping arm 302. The abutting members 400 are distributed in two columns on the upper part of the clamping assembly 300, and the orientations of the two columns are opposite. The communication grooves 308 correspond to the abutting members 400 one by one, and one end of the abutting member 400 passes through the communication groove 308;

[0047] After the clamping assembly 300 clamps the silicon crystal stone, the abutting member 400 contacts the outer side surface of the silicon crystal stone, increasing the friction force between the abutting member 400 and the clamping assembly 300, so that the clamping is more stable.

[0048] The abutting member 400 includes an abutting plate 401, a contact mold 402, a spring plate 403 and a fixing seat 404.

[0054] Two clamping assemblies 300 that can approach or separate from each other form a group.

[0055] The cutting machine is arranged on the bracket and is slidably connected to the base 101.

[0056] The specific implementation manner is as follows: The electromagnet 107 generates a magnetic field to make the frames 301 above and below the electromagnet 107 approach each other. The frames 301 drive the two clamping arms 302 to approach each other as well, so as to clamp the crystalline silicon stone therein.
