Problems solved by technology

However, if figure 2 As shown, when the thickness of the film F varies greatly, since the distance between the coating die head 120 and the surface of the conveying roller 110 is fixed, the thickness of the coating material C formed on the film F will be inconsistent.
Especially when a part of the film F is thick, the coating material C may be easily peeled off from the film F due to insufficient thickness, or the coating material C may not be able to provide normal functions due to insufficient thickness

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0040] Please refer to image 3 , image 3 is a schematic diagram of the film coating apparatus of the present invention. As shown in FIG. 3 , the film coating device 200 of the present invention includes a first roller 210 , a coating die 220 and a second roller 230 . The first roller 210 has a rigid surface. For example, the first roller 210 may be a metal roller, but the invention is not limited thereto. Furthermore, the rigid surface of the first roller 210 may be a smooth surface. The coating die 220 is disposed on one side of the first roller 210 for applying a coating material C on the rigid surface of the first roller 210 . In addition, the coating die 220 and the rigi...

Abstract

The invention discloses a film coating device and a film coating method. The film coating device comprises a first roller, a coating die head, and a second roller, the first roller comprises a rigid surface, the coating die head is arranged at one side of the first roller and used for applying a coating material to the rigid surface of the first roller, the second roller comprises an elastic surface used for conveying a film and being abutted against the rigid surface of the first roller, and the directions of the tangential speeds of the rigid surface of the first roller and the elastic surface of the second roller at the abut joint position are opposite when the first roller and the second roller rotate. According to the film coating device, the uniformity of the thickness of the coating material can be improved.

Description

technical field [0001] The invention relates to a thin film coating device and a thin film coating method, in particular to a thin film coating device and a thin film coating method which can improve the thickness uniformity of coating materials. Background technique [0002] Please refer to figure 1 , figure 1 It is a schematic diagram of a conventional film coating device. As shown in FIG. 1 , the existing film coating device 100 includes a conveying roller 110 for conveying a film F, and a coating die 120 for directly coating the coating material C on the film F. In order to make the thickness of the coating material C formed on the film F consistent, the coating die 120 and the surface of the conveying roller 110 are separated by a fixed distance. However, if figure 2 As shown, when the thickness of the film F varies greatly, since the distance between the coating die 120 and the surface of the conveying roller 110 is fixed, the thickness of the coating material C f...
