Description

Technical Field

[0001] The present disclosure relates to the field of glass technology, and in particular to a system for correcting thickness differences at four corners of carrier glass. Background Art

[0002] How to increase corporate benefits and reduce production costs is the top priority for every company, and improving production efficiency is the most direct way to reduce costs.

[0003] During the packaging process of liquid crystal substrate glass, the robot arm must alternately load the spacer paper and substrate glass onto the A-frame. Due to the deformation of the substrate glass after loading, the difference between different A-frames and the deformation of the spacer paper, after loading hundreds of pieces, the difference between the four corners of the glass and the paper exceeds the required value, and the change pattern of the difference in thickness of the four corners is different for different loads. During the loading process, the thickness of the four corners must be measured manually with a steel ruler every hour and the difference in the four corners must be calculated manually. If any two differences exceed the requirements, the robot arm placement posture must be manually adjusted. If the difference is too large, it cannot be compensated. In addition, during the packaging process, personnel measure regularly, which seriously reduces production efficiency. Personnel frequently work in the robot operation area, which poses a greater personal safety hazard and a hidden danger to packaging quality. Products packaged according to this process are prone to left and right deviations during the later transportation process, affecting product quality. When customers use them, it is easy to fail to take the film, causing customer losses and complaints. Summary of the invention
