[0002] The full name of the polarizer is a polarizer. The imaging of a liquid crystal display must rely on polarized light. All liquid crystals have two front and rear polarizers that are attached to the liquid crystal glass to form a liquid crystal sheet with a total thickness of about 1mm. The reason why the polarizer is called Polarizer, because the polarizer facing the eyes of an ordinary liquid crystal display is frosted to dissipate surface reflections and scatter light to increase the viewing angle of the liquid crystal display. Polarizers are mainly divided into iodine-based polarizers and dye-based polarizers There are two kinds of films, the former is easy to obtain the optical characteristics of high transmittance and high degree of polarization, but the ability to withstand high temperature and high humidity is poor, and the latter is not easy to obtain the optical characteristics of high transmittance and high degree of polarization, but the high temperature resistance is high The wet ability is better. The cutting of traditional polarizers mainly uses fully automatic large-scale punching equipment to punch polarizers. Practical punching equipment itself is relatively expensive, and the cost of mold equipment used in the cutting process is also high. The following problems will occur during the die-cutting process:

[0003] 1. When using a cutting tool to cut the polarizer into pieces, the polarizer between the cutting points is likely to be shifted or upturned, and this phenomenon is also likely to cause inward bending at the cutting fracture of the polarizing disc, resulting in the cutting fracture The quality is poor, and at the same time, the cutting knife is prone to shaking during work, which makes the cutting point shift and causes the cutting end surface to be uneven;

[0004] 2. After the overall cutting of the polarizer is completed, the method of manually picking up the polarizer pieces one by one is usually used, which increases the working time and labor intensity of the workers, and reduces the work efficiency. The overall utilization of the equipment is lower
