Description

Technical Field

[0001] This utility model relates to the field of graphite base processing technology, specifically a positioning device for graphite base processing. Background Technology

[0002] Graphite substrates are fundamental components used in specific fields, typically made of high-purity graphite. In some cases, a silicon carbide (SiC) layer is coated onto the surface of the graphite substrate, forming a SiC-coated graphite substrate. SiC-coated graphite substrates offer numerous advantages, including excellent high-temperature resistance and corrosion resistance, making them suitable for various extreme conditions, especially in high-temperature, corrosive, and abrasive environments. SiC-coated graphite substrates play a crucial role in metal-organic chemical vapor deposition (MOCVD). MOCVD technology is widely used in semiconductors, optoelectronics, and materials science for the fabrication of thin films and coatings. The thermal stability and chemical inertness of the SiC coating ensure the substrate's stability at high temperatures, reduce reactions with corrosive gases, and ensure the high purity and consistency of semiconductor thin films. Furthermore, the SiC coating can influence the interaction between the thin film and the substrate, precisely controlling material growth and interface quality, reducing impurity contamination, and ensuring the high purity of epitaxial thin films.

The transmission column 51 supports the swing arm 52, and the movable groove 53 fixes the bearing 6 while providing space for the positioning wheel 7 to move. The transmission column 51 drives the swing arm 52 to rotate, bringing one end of the swing arm 52 close to the base for positioning. The bearing 6 supports and limits the positioning wheel 7, allowing it to rotate while the base is moving to prevent friction. The positioning wheel 7 then pushes the base from four directions to complete its positioning. The gear 8 drives the transmission column 51 to rotate, and the limiting rod 9 limits the movement of the moving frame 10 to prevent it from shifting during movement. The movable frame 10 can move left and right on the limiting rod 9. When the movable frame 10 moves, it will drive the toothed plate 11 to move. The toothed plate 11 can drive the gear 8 to rotate, thereby driving the transmission column 51 to rotate. When the base is placed on the support base 3, the pressure sensor 12 senses it and starts the bidirectional motor 14 to position the base plate. The rubber pad 13 can protect the pressure sensor 12. The bidirectional motor 14 can drive the screw 15 to rotate. The screw 15 can drive the movable frame 10 to move. The direction of movement of the movable frame 10 can be controlled by controlling the rotation direction of the bidirectional motor 14. The threaded hole 16 can drive the movable frame 10 to move when the screw 15 rotates. After the base is positioned, the base is prevented from shifting.

[0038] In summary, this positioning device for graphite base processing, by setting a support base 3, prevents the base from shifting after positioning by placing the base on top of the support base 3 during use. This solves the problem that existing graphite bases need to be positioned during processing to avoid shifting and affecting the processing.
