The invention provides a method for edging liquid crystal display panels, comprising the following steps, (1) providing a mother board of the liquid crystal display panels; (2) cutting the mother board of the liquid crystal panels, separating out multiple liquid crystal display panels and removing waste material areas; (3) taking images of terminal areas; (4) judging whether at least one of obscuration layers of the waste material areas is sensed or not, if so, the coverage of alignment marks by the obscuration layers is indicated and a fifth step is executed; if not, a sixth step is executed; (5) giving an alarm and removing the waste material areas; (6) implementing image scanning on the terminal areas; (7) judging whether the images of cracks of the waste material areas are taken or not, if so, the fifth step is executed; if not, an eighth step is executed; (8) edging the liquid crystal display panels without the waste material areas. The invention also provides grinding equipment. By the adoption of the method for edging the liquid crystal display panels and the edging equipment, the yield rate of the liquid crystal display panels can be improved.
Description
technical field [0001] The invention relates to the field of manufacturing liquid crystal display panels, in particular to an edge grinding method and edge grinding equipment for liquid crystal display panels. Background technique [0002] Liquid crystal display (Thin Film Transinstor Liquid Crystal Display, TFT-LCD) has become a very common display tool in daily life and work, and the liquid crystal display panel is an important component of the liquid crystal display. [0003] The liquid crystal display panel is usually cut from the mother board of the liquid crystal display panel in the manufacturing process. The mother board of the liquid crystal display panel includes a plurality of liquid crystal display panels. Each liquid crystal display panel includes a lower substrate, an upper substrate arranged on the lower substrate and The liquid crystal layer filled between the lower substrate and the upper substrate, the lower substrate may be a thin film transistor (Thin Fil...
