In order to achieve accurate cutting and splitting of large size liquid glass substrates, a new technology solution was proposed. By using the upper and lower differential positioning of the upper pressure wheel and the lower cutter wheel, the accurate cutting along the same cutting path on the liquid crystal panel was achieved. Through the method that the upper pressure wheel contacts cutting line, the purpose of splitting was achieved, and the waste edges were absorbed by the cylinder and the suction disc. The cutting and splitting process of large size liquid crystal glass substrate are analyzed. The process parameters such as cutter wheel angle selection, cutting pressure, cutting speed of cutter wheel, cutting speed and splitting pressure are set up, and the smooth operation of the equipment is realized..
