Description

Technical Field

[0001] The utility model relates to the technical field of polarizer processing equipment, in particular to an edge grinding device used for polarizer processing. Background Art

[0002] The full name of polarizer is polarizing film. The imaging of LCD must rely on polarized light. All liquid crystals have two polarizing films in the front and back attached to the LCD glass. The reason why polarizing film is called polarizer is because the polarizing film facing the eyes of ordinary LCD is frosted to dissipate surface reflections and scatter light to increase the viewing angle of the LCD.

[0003] When processing polarizers, an edge grinder is needed to grind the edges of the polarizers to improve the quality of polarizer production. However, the existing edge grinders are not convenient for adsorbing and collecting the powder generated during the polarizer grinding process. The dust dispersion can easily cause harm to the health of the workers. In addition, the existing edge grinders have low edge grinding efficiency and are not convenient for adjusting the size of the polarizers. The edge grinding is inconvenient to use. Therefore, improvements are needed to address the existing problems. Utility Model Content
