Method for adhesion of film and apparatus thereof

Abstract

The invention relates to a method for adhesion of film and an apparatus thereof, wherein flake film of the same size of adhesive substrate adhere to the substrate.Above the substrate 2, the film 1 is slanted, sucked, and held on the opposite surface side to a protective film 7 by a suction plate 33 and a tip suction plate 34. An adhesive tape 55 is stuck on the protective film 7, and the adhesive tape 55 is moved reversely at the tip of the film 1 to peel the tip of the protective film 7. A tip suction plate 34 is made to recede from the tip of the film. The tip of the film which peeled the tip of the protective film is joined to the tip of the substrate 2, and they are pressed by a press roller 46. The suction / holding of the film by the suction plate 33 is released. While the substrate 2 is moved with the tip side of the film 1 made a head, the protective film 7 is peeled by the movement of the adhesive tape 55, the film 1 is supplied to the substrate 2, and the film 1 is stuck on the substrate 2 by the press roller 46. According to the invention, the delicate and complicated control of the adsorption and retention capacity is unnecessary, and it is simple and reliable that the film adheres to the substrate without dropping the film on the substrate.

Description

technical field [0001] The invention relates to a film pasting method and a device thereof for pasting a sheet film with a size commensurate with the substrate to be bonded on the substrate. Background technique [0002] In the production process of liquid crystal displays or plasma displays, etc., it will have various functions such as improving the contrast between light and dark or color reproducibility, cutting off electromagnetic waves or infrared rays emitted by the display panel, preventing peripheral images from being reflected on the screen, and preventing damage to the display panel. A permanent film (hereinafter simply referred to as film) is pasted on the surface of a liquid crystal display panel or a plasma display panel (hereinafter referred to as substrate) in a state where two glass plates are pasted together to achieve good image quality. [0003] Paste the film using a film pasting device, with the display surface of the substrate facing up, and supply a sh...

Problems solved by technology

In this case, the transmitted light is shielded and scattered due to the abrasion powder and air bubbles formed around, and the required image quality cannot be obtained, which becomes a cause of image quality degradation and yield reduction

[0014] Due to these problems, delicate and complex control of the adsorption and retention force of the film is required, so it is difficult to stick the film efficiently and in good condition
