The automatic attaching of the polaroid is a key core process in the manufacturing process of the flat-panel display, and the automatic attaching of the polaroid of the optical film body to the glass substrate is realized. The polarizer supplied material is generally a roll material, that is, a strip-shaped polarizer strip is wound on a winding wheel, and the polarizer is cut off according to the size of the produced screen body in the subsequent processing process. The web-shaped polarizer on the winding wheel needs to be completely pulled out during the process and then needs to be subjected to a reel change operation, which requires cutting the web-shaped polarizer on the original winding wheel and adhering the cut portion to the tape head of the new winding wheel. An automatic cutting head is needed to be designed for cutting off the polaroid on the winding wheel.
