Abstract

The invention relates to protective film reposting device and method, which is used for reposting a protective film part after being stripped off an optical sheet on the optical sheet. The protectivefilm reposting device comprises a conveying mechanism, a stripping mechanism and a posting mechanism. The conveying mechanism comprises a plurality of parallel conveying rolls which are used for driving the optical sheet to move towards the first direction. The stripping mechanism is arranged above the conveying mechanism and used for stripping the protective film part off the optical sheet. The posting mechanism is arranged between the conveying rolls and comprises a first roller and a second roller. A channel is formed between the first roller and the second roller; and the optical sheet andthe protective film pass through the channel together to repost the protective film on the optical sheet. The invention can eliminate the effects of anthropogenic factor in the process of reposting the protective film, and greatly improve the productive efficiency and product quality.

Description

technical field

[0001] The present invention relates to a device and method for reattaching a protective film, in particular to a device and method for reapplying a protective film that can remove the influence of human factors. Background technique

[0002] Polarizers have been widely used in various optical instruments and optoelectronic products, such as flat panel displays. Polarizers generally have a protective film. Due to the different tension of the protective film, the four corners around the polarizer will be lifted up or down when pasted, which will affect the production accuracy and product quality of the polarizer.

[0003] For polarizers with problematic protective film coating, the current method is to re-paste the protective film, but this process is generally manual work, and its human factors will affect the effect of the protective film after re-pasting, and it is easy to appear appearance Defective, such as foreign matter, etc. Contents of the inventio...
