Abstract

The invention relates to an anti-fingerprint spray coating method and equipment. The equipment comprises a case, a plasma cleaning linear module and a spray gun linear module, wherein the case is arranged on a material conveying mechanism, the case is provided with a feed inlet and a discharge outlet, and the plasma cleaning linear module and the spray gun linear module are arranged in the case; the plasma cleaning linear module comprises a first guide rail arranged above the conveying trajectory of the material conveying mechanism, a first sliding block, a first motor and a plasma cleaning head connected with a plasma controller, wherein the plasma cleaning head is connected with the first sliding block; the spray gun linear module comprises a second guide rail arranged above the conveying trajectory, a second sliding block, a second motor and a coating feed device connected with a spray coating liquid storage device through a connecting pipe, wherein the coating feed device is provided with a spray gun head and the is connected with the second sliding block. The anti-fingerprint spray coating method and equipment have the advantages that the structure is simple, the production cost is low, the production efficiency is high, the cleaning is thorough, the quality of the produced product is high, the spray coating is uniform, the method and equipment can be widely popularized and the like.

Description

technical field [0001] 　　 The invention relates to plasma cleaning and material spraying technology, in particular to an anti-fingerprint spraying method and equipment. Background technique [0002] With the development of technology, there are more and more touch-screen products. In order to meet the needs of consumers, some manufacturers will coat a layer of anti-fouling and anti-fingerprint film on the surface of the touch-screen glass when producing touch-screen products. , thus reducing the surface friction coefficient of the touch screen glass, making the touch screen anti-dirt, anti-fingerprint and anti-sweat, etc., and improving the texture and feel of the touch screen during use. [0003] In the existing technology, the processing of anti-fouling and anti-fingerprint film can only be realized by vacuum evaporation coating. Moreover, when coating the touch screen with anti-fouling and anti-fingerprint film, the touch screen will be cleaned with plasma cleaning equi...

AI Technical Summary

Problems solved by technology

Moreover, when coating the touch screen with anti-fouling and anti-fingerprint film, the touch screen will be cleaned with plasma cleaning equipment first, and then the cleaned touch screen will be coated with vacuum evaporation coating equipment, so that plasma cleaning equipment and vacuum coating are used. Evaporation coating equipment has two devices, which makes the structure complicated and increases the production cost

Moreover, in the plasma cleaning equipment, multiple linearly arranged plasma cleaning heads are used, which not only has a complex structure, but also increases the production cost

And when cleaning, because the cleaning is not clean, there will be cleaning blind spots, which will affect the coating of the touch screen, making the coating on the touch screen uneven

[0004] Due to the above reasons, the coating of anti-fouling and anti-fingerprint film on the touch screen has problems such as high production cost, low production efficiency and low pass rate of produced products. Therefore, anti-fouling and anti-fingerprint film can only be used on high-end products, such as Apple and products such as Samsung

Most of the 3C products on the market, such as touch screens, window products or glasses, which use glass materials, are not coated with anti-fouling and anti-fingerprint film, especially some products that have entered the market. Most consumers want to protect the touch screen of the product. They will choose to stick a film on the touch screen, which increases the cost of consumers, and the films in the market are all PET films, which seriously affect the transmittance of the touch screen on the surface of the product, and the use time is short, and the entire surface of the film is easily damaged. Scratches will seriously affect the appearance and effect of the product
