Problems solved by technology

I268375 and JP 10-123504 mainly emphasize that the direction of force to tear off the release film should be flat on the surface of the substrate to prevent the substrate from being broken by the bending moment force. However, it does not propose how to fix the substrate, especially the small-sized substrate. It is even more difficult to fix effectively to tear off the release film

Embodiment Construction

[0066] The technical solutions of the present invention will be further described in more detail in conjunction with the accompanying drawings and specific embodiments.

[0067] Please refer to figure 1 and figure 2 As shown, the film peeling device provided by the first embodiment of the present invention is used to peel off the film 91 from the substrate 90 , wherein the film peeling device includes a base 10 , a fixing member 20 , a clamp 30 , and a transmission device 40 . The substrate 90 may be a glass substrate including a polarizer, and the outer surface of the polarizer is covered with a film 91 for release. The polarizer is pasted on the substrate 90 together with the film 91 , so the film 91 must be torn off before the optical properties of the polarizer can be exerted.

[0068] refer to figure 1 and figure 2 As shown, the base 10 includes a bottom plate 11 and two side walls 12 , the two side walls 12 are disposed on the bottom plate 11 parallel to each other...

Abstract

The invention discloses a sticking film tearing-down device which implements a sticking film tearing-down method to tear down the sticking film from a substrate. The sticking film tearing-down device comprises a fixed piece, a clamp and a transmission device. The fixed piece has a top surface, a bottom surface and a slit; the slit is communicated with the top surface and the bottom surface; the substrate is arranged below the fixed piece, so that the bottom surface of the fixed piece can contact the substrate. The edge part of the sticking film is firstly stripped, and the stripped edge part passes through the slit of the fixed piece. The clamp is movably arranged on the bottom surface and clamps the edge part of the sticking film through the slit. The transmission device drives the clamp away from the top surface and the slit; the fixed piece enables the substrate to be restricted below the fixed piece, so that the clamp can tear down the sticking film from the substrate.

Description

technical field [0001] The invention relates to a device and method for peeling off a film, in particular to a device and method for peeling off a film applied to a thin glass polarizing plate. Background technique [0002] Liquid crystal display panels are mainly composed of glass substrates, polarizers, transparent electrodes, alignment films, liquid crystal films, and color filters. The polarizer is arranged on a release film, and the side without the release film is directly attached to the glass substrate. After the release film is removed, the work of fixing the polarizer on the glass substrate can be quickly completed. [0003] In the traditional release mill tearing operation, a blade is inserted between the release film and the polarizer manually, and the edge of the release film is peeled off. Then the staff grasps the stripped substrate with one hand, and grasps the edge of the stripped film with the other hand, and slowly tears off the release film. [0004] Wh...
