Roll-to-roll vacuum coating equipment for coating anti-fingerprint film

Abstract

The invention relates to the technical field of vacuum coating equipment, in particular to roll-to-roll vacuum coating equipment for coating an anti-fingerprint film. The roll-to-roll vacuum coating equipment comprises a vacuum chamber, a coating roller is arranged in the vacuum chamber, and a winding and unwinding chamber, a magnetron sputtering coating chamber, a first air isolation chamber, a gaseous evaporation coating chamber and a second air isolation chamber are sequentially arranged along the circumferential direction of the coating roller; an unwinding roller, a first guide roller, asecond guide roller and a winding roller are arranged in the winding and unwinding chamber used for winding a base material; the base material discharged from the unwinding roller sequentially passesthrough a first guide roller, the coating roller, a second guide roller and a winding roller; a magnetron sputtering coating system is arranged in the magnetron sputtering coating chamber; and the vacuum coating equipment further comprises a gaseous evaporation coating system used for coating the anti-fingerprint film. According to the roll-to-roll vacuum coating equipment for coating the anti-fingerprint film provided by the invention, continuous coating of the anti-fingerprint film can be realized, other film layers can also be coated, and the anti-fingerprint film and other film layers canbe coated on the same vacuum coating equipment, so that the production efficiency is greatly improved, the equipment investment is also reduced, and energy conservation and consumption reduction are realized.

Description

technical field [0001] The invention relates to the technical field of vacuum coating equipment, in particular to a roll-to-roll vacuum coating equipment for coating an anti-fingerprint film. Background technique [0002] The traditional anti-fingerprint coating methods are mainly spraying method and vacuum evaporation coating method. The spraying method is generally completed in the atmosphere, but the spraying accuracy is generally low, the film uniformity is poor, and the process is not stable; the effect of vacuum evaporation coating method Good, but only suitable for use on stand-alone equipment, there is no way to achieve continuous deposition. For continuous coating equipment, such as assembly line coating equipment or winding coating equipment, it is difficult to achieve online continuous coating of anti-fingerprint film. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the object of the present invention is to provide...
