Description

Technical Field

[0001] The utility model relates to the technical field of LCD, in particular to an auxiliary fixture for LCD cracks. Background Art

[0002] Liquid crystal glass substrate (LCD) is a basic component of liquid crystal display devices. During the production process of LCD screens, the two sides of the LCD excess waste edges need to be pre-cut according to preset sizes, and then the excess waste edges of the LCD need to be separated along the corresponding cutting lines on the two sides.

[0003] In the prior art, the excess waste edges of the pre-cut LCD are separated manually, i.e., artificial splitting. However, the efficiency of manual splitting is low and cannot meet production needs. In addition, the human body carries static electricity. Even if anti-static equipment is worn, there are still situations where the anti-static equipment fails or the wearer does not wear it properly, which may lead to the LCD being punctured and damaged. In addition, artificial splitting requires time-consuming and labor-intensive pre-job training. The quality of manual splitting is difficult to achieve uniformity, and the defective rate remains high. Utility Model Content
