A sapphire crystal ingot c-direction rod-free jig without glue

Abstract

The invention discloses a sapphire crystal ingot C-direction bar digging free-cementing fixture. The fixture comprises a fixture body, wherein the fixture body comprises a base plate, the base plate is provided with a resin plate, the resin plate is provided with a groove which has the same side face with the sapphire crystal ingot, lock threaded rods are symmetrically arranged at the left and right sides of the groove, the lock threaded rods are provided with pressing blocks and limiting parts in a sleeved mode, when C-direction bar digging is conducted on the sapphire crystal ingot, the sapphire crystal ingot needs to be placed in an edge-on mode, the resin plate is provided with the groove which has the same side face with the sapphire crystal ingot, everywhere of the groove is in contact with the bottom of the sapphire crystal ingot so as to be capable of providing braced force for the contacted parts of the bottom of the sapphire crystal ingot, therefore, a bottom limiting effect can be achieved on the crystal ingot which is placed in the edge-on mode through the groove, the situation that the bar digging surface of the sapphire crystal ingot is parallel to the base plate is guaranteed, the pressing blocks on the lock threaded rods arranged at the two sides of the groove can conduct limiting on the sapphire crystal ingot from the top of the sapphire crystal ingot, the pressing blocks are limited by the limiting parts to move upwards so that the pressing blocks can exert a downward pressure on the top of the sapphire crystal ingot, and the groove which is matched with the bottom of the sapphire crystal ingot is capable of making the sapphire crystal ingot fix on the fixture in a side-direction mode.

Description

technical field [0001] The invention relates to the technical field of sapphire crystal ingot squaring, in particular to a non-adhesive clamp for sapphire crystal ingot C-direction rod extraction. Background technique [0002] The sapphire crystal ingot produced by the heat exchange method is usually in the shape of a truncated cone, which has an A / C / M axis. In the prior art, when the sapphire crystal ingot is pulled out in the C direction, because the C direction of the sapphire crystal ingot is parallel The direction of the horizontal plane, so the sapphire crystal ingot needs to be cut vertically, and then the sapphire crystal ingot is erected sideways and removed from the section. Usually, AB glue is used to fix the sapphire crystal ingot on a bottom plate. After the AB glue is dry and solidified, the sapphire crystal The ingot is used for digging out rods. However, this method has many disadvantages: the amount of AB glue that needs to be used to fix the sapphire cryst...

AI Technical Summary

Problems solved by technology

However, this approach has many disadvantages: the amount of AB glue required to directly fix the sapphire crystal ingot on the base plate through AB glue is large, and it takes a long time to wait for the AB glue to dry and fix the sapphire crystal ingot, which increases the production cost. It also reduces the production efficiency; the sapphire crystal ingot is fixed on the bottom plate by AB glue when standing sideways. operators
