Description

Technical Field

[0001] The utility model relates to the technical field of sapphire processing, in particular to a tool for clamping the bottom surface of a crystal ingot. Background Art

[0002] There is a big difference between artificially synthesized sapphire and natural sapphire. Artificially synthesized sapphire is generally used to make watch mirrors, mobile phone films, etc. During the specific production, the aluminum oxide raw material is placed in a crystal growth furnace, and then the entire furnace is evacuated to a vacuum. The high temperature completely melts the aluminum oxide raw material in the furnace to grow crystals. After annealing and cooling, a cylindrical sapphire crystal ingot is produced. When producing watch mirrors, the sapphire crystal ingot needs to be hollowed out. When producing square products such as mobile phone films, the sapphire crystal ingot needs to be cut into bricks according to size. The process of cutting the sapphire crystal ingot into bricks is called square cutting.

[0003] When squaring a sapphire ingot, the curved surface of the sapphire ingot needs to be fixed to the cutting platform to facilitate subsequent cutting. In the prior art, the sapphire ingot is usually fixed to the cutting platform by AB glue bonding. However, since the equipment will vibrate during cutting, and the cutting force point is not in the middle of the sapphire ingot, the force on the sapphire ingot is unbalanced, which is prone to debonding.

[0004] Through the improvement of the existing technology, people now usually use clamping tools to fix sapphire crystal ingots. The existing clamping tools for sapphire crystal ingots generally include two groups of clamping components, each group of clamping components is symmetrically provided with two clamps, and the two groups of clamping components clamp the sapphire crystal ingot from the two flat sides of the sapphire crystal ingot and the two ends of the curved surface of the sapphire crystal ingot respectively. Since the curved side surface of the sapphire crystal ingot has an arc, whether a flat clamp or a curved clamp is used, an oblique upward force will be applied to the curved side surface of the sapphire crystal ingot, which can easily cause the sapphire crystal ingot to leave the cutting platform. Not only is the clamping effect poor, but the surface of the sapphire crystal ingot is also easily damaged.

[0005] In summary, there is a need for a more stable bottom surface clamping tool for the crystal ingot. Utility Model Content
