Abstract
An automatic corner lift-off apparatus for a polarizer of a liquid crystal display (LCD) panel is disclosed, which is suitable for use in a process of removing a polarizer during manufacturing of an LCD panel and comprises: a front clip, comprising a long arm and a short arm which intersect with each other to substantially form an “L” shape; a back clip, spaced apart from the front clip and being capable of cooperating with the front clip to perform a clipping action; and at least one sensor disposed on the front clip or the back clip, being configured to sense whether the polarizer has been successfully lifted off. Thereby, the present disclosure allows for fully automatic polarizer removing operations and can reduce work-related injuries and improve the success ratio of and efficiency of removing the polarizer.
