Abstract

The invention relates to an optical film continuous automatic film covering device and a working method, the optical film continuous automatic film covering device comprises an unwinding device, a gluing device, a film covering device and a winding device, an optical film is unwound from the unwinding device, glue is coated on the film through the gluing device, the optical film is separated from a protective film on the film covering device, the optical film covers the plate surface, and the protective film is conveyed to the winding device to be recycled; the film covering device comprises a conveying belt, a first pressing device, a second pressing device and a drying device are arranged on the conveying belt, and the drying device is arranged between the first pressing device and the second pressing device; and the upper part of the conveying belt is also provided with a separation block for separating the protective film from the optical film. The protective film is separated through the separation block, and the optical film covers the plate surface, so that wrinkles are reduced; the covered film passes through the first pressing device, and the covered film is further flattened and pressed; and the film laminating machine is suitable for automatic production.

Description

Technical field[0001]The present invention belongs to the field of film, and in particular, to an optical film continuous automatic coating apparatus and a working method.Background technique[0002]The main application of the optical film sheet is a display screen for a backlight module, a television, a flat plate, a mobile phone such as a liquid crystal display; a three-dimensional display of 3D film, airport, high-speed rail, road and other reflective films; LED energy-saving lamps The uniform light film; various types of electronics housing, hardening films and solar back plate assemblies of the home appliance control panel. Existing coating devices, single, simple structure, can't exclude wrinkles, debris, etc. when the film is filmed, and the product is high and the film is low.Inventive content[0003]The object of the invention is an object of the present invention to provide an optical film continuous automatic coating apparatus and a working method, a structural design is reas...
