US 9,517,915 B2 · Film coating apparatus and film coating method

Abstract

Embodiments of the present invention provide a film coating apparatus and a film coating method, relating to the field of manufacturing of display devices. The film coating apparatus comprises a feeding unit, an attaching unit and a cutting unit, which are arranged on a base, wherein the feeding unit is configured to feed a film to be attached to the surface of a product; the attaching unit is connected to the feeding unit and configured to attach the film onto the surface of the product; and the cutting unit is connected to the feeding unit and configured to cut the film. According to the present invention, the film coating of a light guide plate, a semi-finished backlight product and a finished backlight product can be achieved, the labor intensity of operators is greatly reduced, the productivity is liberated, and the production efficiency is further improved. Meanwhile, coating deviation resulted from human factors is avoided, and the bottleneck in the automation of producing TFT-LCDs is overcome.
