Embodiment Construction

[0022] The detailed description and technical content of the present invention are now described as follows in conjunction with the accompanying drawings. The following description of the embodiments refers to the accompanying figures to illustrate specific embodiments in which the invention can be practiced.

[0023] Please refer to FIG. 3 , which is a schematic diagram of the adhesion plate 38 of the film tearing mechanism of the present invention. The film tearing mechanism includes a pressure head 30 , two supporting wheels 32 , 34 and an adhesive tape 36 . The pressing head 30 is used for clamping the sheet 38 , and the lower surface of the sheet 38 has an adhesive film 40 . The support wheels 32, 34 are respectively located on the left and right sides below the pressure head 30. The adhesive tape 36 is set on the supporting wheel 32 and passed around the supporting wheel 34 , or the adhesive tape 36 is set on the supporting wheel 34 and passed around the supporting whe...

Abstract

The invention discloses a film tearing mechanism and a film tearing method; the film tearing mechanism comprises a press, two supporting wheels and an adhesive tape. The press is used for clamping sheet; the lower surface of the sheet is provided with a glue film; two supporting wheels are respectively arranged at two sides below the press; the adhesive tape is arranged at one supporting wheel and surrounds the other supporting wheel; the adhesion surface of the adhesive tape faces to the glue film and leads the back towards the two supporting wheels, wherein, when the press is reduced, the sheet is arranged on the bonding surface; the sheet is arranged between the two supporting wheels and is provided with distance respectively in the horizontal direction; the sheet is not bumped with two supporting wheels due to extrusion; furthermore, the glue film of the sheet forms surface contact with the bonding surface. When the film tearing mechanism is used to tear the glue film, as the sheet is not bumped to the two supporting wheels by extrusion, sheet-breaking problem can be avoided; furthermore, the glue film and the adhesive tape form the surface contact, and the contact area of the flue film is increased, thus ensuring the success rate of the film tearing.

Description

technical field [0001] The invention discloses a film tearing mechanism and a film tearing method, in particular to a film tearing mechanism and a film tearing method capable of ensuring the success rate of film tearing and avoiding fragmentation problems. Background technique [0002] The polarizer attached to the surface of the liquid crystal display (LCD) panel has a protective film to protect the polarizer from being damaged by collision during operation, and on the other hand, it also avoids air particles in the working environment. Or the problem of dust falling on the polarizer. The traditional method of tearing the film of the polarizer is manual tearing, which is inefficient, and the cleanliness of the working environment of manual tearing of the film is generally low. After the protective film of the polarizer is torn off, the particles or dust suspended in the air are easy to If it falls on the polarizer, it is easy to generate assembly foreign matter during the ...
