Coating device

Abstract

The invention relates to a coating device comprising a plurality of plating solution units and a heating module. Each plating solution unit comprises a plating solution tank for containing solution tobe plated, a first plating solution roller adjacent to the plating solution tank and at least one first spraying module, wherein the first spraying module is provided with a solution-absorbing end and a solution-spraying end; the solution-absorbing end is immerged in the plating solution tank; the liquid-spraying end is opposite to the first plating solution roller so as to spray the solution tobe plated upwards; a substrate to be coated coats the first plating solution rollers contained in the plurality of plating solution units, at least one of the first plating solution rollers rotates and drives the substrate to be coated to circularly operate; the heating module comprises at least one heating unit which is arranged between any two adjacent first plating solution rollers.

Description

technical field [0001] The invention relates to a coating device. Background technique [0002] With the development of optical products, the application range of optical components is becoming wider and wider. Correspondingly, the industry adopts various methods to manufacture optical elements to meet market demand for optical elements of different specifications (see "Fabrication of Diffractive Optical Lens for Beam splitting Using LIGA Process", Mechatronics and Automation, Proceedings of the 2006 IEEE International Conference on, pp.1242-1247, 2006.06). Typically, fabricated optical components undergo further processing to obtain good properties for the application. [0003] The coating process is one of the important steps in the subsequent processing. Coating refers to coating single-layer or multi-layer thin films on the surface of optical components by physical or chemical methods, using the interference of incident, reflected and transmitted light at the film int...

Problems solved by technology

[0004] However, in the existing coating technology, the coating device generally performs coating on one plane, so the space utilization rate is low

The newly developed coating-type long-film technology (Roll-to-roll technology), the wavy material sent continuously from the feeding reel, evenly coats the liquid film-forming agent on the processing part, but the existing coating-type long-film Technology cannot cycle coating, when coating multi-layer film, need to go through many times of installation and disassembly, many procedures, not easy to operate
