Problems solved by technology

[0003] When the polarizer is in use, a layer of film on the polarizer needs to be removed. In the prior art, the film removal method is mostly through manual tearing of the film. Manual tearing of the film is uneven, and it is easy to cause the film to remain on the polarizer. Manual tearing of the film low efficiency

Abstract

The invention discloses a polarizing film tearing mechanism which comprises a film tearing machine frame, a first fixing plate and a second fixing plate are fixedly installed on the film tearing machine frame, a gap is formed between the first fixing plate and the second fixing plate, and a baffle is fixedly installed at the bottom of the first fixing plate. A corner of a film on a polaroid is torn off, the polaroid is moved to a second fixing plate along a conveying shaft on a conveying frame, the corner of the film is inserted into a gap between a first fixing plate and the second fixing plate, a driving motor is started, then a rubber coating roller is driven to rotate, piston rods of a first air cylinder and a second air cylinder are started to stretch out, and then the polaroid is cut off. The third rolling shaft is driven to make contact with the rubber coating roller to clamp the corner of the thin film, the rubber coating roller rotates to tear off the thin film from the polaroid, the mechanical mechanism exerts force evenly, the thin film can be torn off integrally, and the film tearing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of film tearing equipment, in particular to a polarizing film tearing mechanism. Background technique [0002] The full name of the polarizer is a polarizer or a polarizing film. The imaging of a liquid crystal display must rely on polarized light. All liquid crystals have two front and rear polarizers attached to the liquid crystal glass to form a liquid crystal sheet with a total thickness of about 1mm. Any polarizer and liquid crystal cannot display images, and 3D glasses use this principle. [0003] When the polarizer is in use, a layer of film on the polarizer needs to be removed. In the prior art, the film removal method is mostly through manual tearing of the film. Manual tearing of the film is uneven, and it is easy to cause the film to remain on the polarizer. Manual tearing of the film low efficiency. Contents of the invention [0004] In order to solve the technical problems mentioned in the b...
