Description

Technical Field

[0001] The utility model relates to the technical field of LCD, in particular to an automatic particle separation device for LCD panels. 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 LCD needs to be cut on both sides, and then the LCD needs to be divided into single pieces of glass of several display screen sizes along the corresponding cutting lines on the two sides.

[0003] In the prior art, pre-cut LCDs are manually sorted, i.e., manual sorting. However, manual sorting is inefficient in breaking films manually 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 the equipment properly, which may lead to the LCD being damaged by breakdown. In addition, manual sorting requires time-consuming and labor-intensive pre-job training. The quality of manual breaking is difficult to achieve uniformity, and the defective rate remains high.
