How to break LCD glass

Abstract

A method for breaking liquid crystal glass plates. In the first step, when the formed glass plate is sent out from the furnace, the cross-cutting machine is synchronously lowered and started; in the second step, after the cutting board strip clamping device on the cross-cutting machine is clamped, the plate is broken The robot sucks the formed glass plate from outside the effective surfaces on both sides of the formed glass plate, and descends synchronously with the formed glass plate; the third step, the cross-cutting machine draws the formed glass plate according to the set size; the fourth step, the cross-cutting machine After the scribing is completed, the blade returns, and the cross-cutting machine returns to the original position for standby; after the board breaking robot confirms that the marking is completed, it breaks the board according to the board breaking angle of 7 to 10 degrees, otherwise it does not perform the board breaking action, and returns to the original position for waiting The next cycle starts; in the fifth step, after the plate-breaking robot finishes breaking the plate, the intact glass plate is placed on the conveyor belt and sent to the next process, the damaged glass plate is thrown into the waste chute, and the plate-breaking robot returns to the original position to stand by. The invention reduces the probability of abnormal failure of the equipment and improves the yield rate of the molding process.

Description

technical field [0001] The invention belongs to the field of liquid crystal glass production, and in particular relates to a method for breaking plates of liquid crystal glass. Background technique [0002] In the production of liquid crystal glass, it is necessary to cut the formed glass plate flowing out of the furnace according to fixed specifications. After the cutting is completed, the glass must be broken before it can flow into the next process. The breaking equipment and action have a great impact on the quality of the product. The robot is a kind of equipment with high degree of automation and precision, and it can be used here to complete this work well. [0003] In the production of liquid crystal glass, forming is the most critical process, and the plate breaking robot is the most critical piece of equipment in this process. The plate breaking robot is mainly responsible for breaking the glass plate cut by the cross-cutting machine and transporting it to the con...

AI Technical Summary

Problems solved by technology

[0004] 1) The movement of the robot is unstable, and it is easy to cause the plate to break during the forming process, resulting in interruption of normal production. It takes more than an hour to recover, which has a great impact on the production output and process stability;
