Abstract

The invention relates to the technical field of crystal bar fixtures, in particular to an automatic orientation fixture for OF surface processing of a sapphire crystal bar. The automatic orientation fixture comprises an upper fixture and a lower fixture detachably connected; a V-shaped groove is formed in the upper surface of the lower fixture; the upper fixture is used for fixing the sapphire crystal bar in the V-shaped groove; the V-shaped groove includes a left inclined surface and a right inclined surface symmetrically distributed on two sides; the left inclined surface and the right inclined surface are both provided with symmetric pulley grooves; rotating shafts are mounted in the pulley grooves, and are coated with rollers; the rotating shafts are parallel to the length direction of the lower fixture; and the rollers are tangential to the left inclined surface / the right inclined surface, or are slightly projected out of the left inclined surface / the right inclined surface. The rotating shafts on the left inclined surface and the right inclined surface are both connected with synchronous motors. The sapphire crystal bar positioning fixture is divided into upper and lower two parts; and the rollers are added on the left inclined surface and the right inclined surface, so that the crystal bar can automatically rotate to adjust the position, the position of the sapphire crystal bar before processing is conveniently adjusted, the positioning is precise, and labors are saved.

Description

technical field [0001] The invention relates to the technical field of crystal rod fixtures, in particular to an automatic orientation fixture for processing the OF surface of a sapphire crystal rod. Background technique [0002] Sapphire crystal is an anisotropic crystal material with excellent electrical, optical, thermal and mechanical properties. In recent years, with the expansion of the application of crystals in optoelectronics and information industries, high requirements have been placed on the processing accuracy of wafers, and crystal materials used as epitaxial growth substrates have put forward strict requirements on the processing accuracy of crystal plane angle orientation. Therefore, it is an important link to produce high-quality devices and substrates to ensure the crystal plane angle orientation accuracy in the processing of crystals from blanks to finished products. [0003] The processing technology of the sapphire ingot is as follows: digging out the i...
