Abstract

The invention discloses a diffusion film feed mechanism which comprises a machine frame, a diffusion film winding device, a base material, a protective film winding device, a film peeling device and a membrane conveying device. The film peeling device comprises a film peeling upper plate and a film peeling lower plate. The bottom plane of the film peeling upper plate and the top plane of the film peeling lower plate are parallel and spaced by a certain distance. The membrane conveying device is located beside the film peeling device. The height of a conveying belt of the membrane conveying device is slightly smaller than that of the top plane of the film peeling lower plate. During operation, the free end of diffusion film penetrates through the space between the film peeling upper plate and the film peeling lower plate, an operator separates a membrane at the free end of the diffusion film from the base material and protective film, the membrane stretches across the film peeling lower plate and the conveying belt of the membrane conveying device, and the base material and the protective film are wound around a base material winding device and the protective film winding device in an inclined-downwards direction and an inclined-upwards direction respectively through a gap between the film peeling lower plate and the membrane conveying device.

Description

technical field [0001] The invention relates to a film laminating machine, in particular to a diffusion film feeding mechanism of a backlight module film laminating machine. Background technique [0002] Backlight is a kind of light source located behind the liquid crystal display on the mobile phone, MP4 and GPS, and its luminous effect will directly affect the visual effect of the liquid crystal display module. LCD itself does not emit light, it displays graphics or characters is the result of its light modulation. The current backlight module is mainly used in conjunction with a diffusion film, an enhancement film, and a diffusion film to achieve the purpose of uniformity and concentration of light. At present, films such as diffusion film, brightness enhancement film, and diffusion film are generally pasted on the backlight module by using a film laminating machine. The conveying device is sent to the dust removal device for dust removal, and then sent to the film stic...
