Description

Clamping mechanism for edging polarizer Technical Field The application relates to the technical field of polarizer processing, in particular to a clamping mechanism for edging a polarizer. Background The polarizer is called a polarizing plate, the imaging of the liquid crystal display is required to depend on polarized light, all liquid crystals are provided with a front polarizing plate and a rear polarizing plate which are tightly attached to liquid crystal glass to form a liquid crystal plate with the total thickness of about 1mm, if any one polarizer is omitted, the liquid crystal plate cannot display images, the 3D glasses apply the principle, the polarizing plate is called a polarizer because the polarizer facing eyes of the common liquid crystal display is frosted to dissipate surface reflection, and light is scattered to increase the visual angle of the liquid crystal display. After the polaroid is cut, the cutting boundary of the polaroid needs to be polished, so that the side quality of the polaroid is ensured, when the polaroid polisher polishes the rectangular polaroid, a plurality of polaroids are stacked together and are placed on polishing equipment together, the plurality of polaroids are clamped, and then the plurality of polaroids are polished together. However, when the edges of the polarizers are polished, the positions of the polarizers in the middle are easily shifted, and then the unpolished polarizers are required to be screened and reprocessed in the middle, so that the polishing efficiency of the polarizers is low. Disclosure of Invention Aiming at the problems in the prior art, the application provides the clamping mechanism for the edge grinding of the polaroid, which has the advantages that the position of the polaroid is not easy to deviate when the edge part of the polaroid is ground, so that secondary processing of the ground polaroid is not needed, and the grinding efficiency of the polaroid is greatly improved.
