Method for manufacturing stainless steel screen printing plate in shielding way

Abstract

The invention discloses a method for manufacturing a stainless steel screen printing plate in a shielding way. The method comprises the following steps of S1, taking a stainless steel screen, and fixing the stainless steel screen to a specific screen frame to form a spread screen plate; S2, carrying out cleaning, dust removal and degreasing on the spread screen plate; S3, coating the stainless steel screen with a photosensitive adhesive or a resin material capable of realizing the adhesion function; S4, manufacturing a pattern to be printed on a metal plate; S5, fixing the metal plate to the stainless steel screen through vacuum adsorption or a separable adhesive; S6, removing the photosensitive adhesive or the resin material capable of realizing the adhesion function on the stainless steel screen in a pattern printed area through laser; S7, removing the metal plate used for shielding to complete manufacturing; and S8, carrying out cleaning, packaging and identifying on the stainless steel screen printing plate. Through the method, the dependency of the stainless steel screen printing plate on materials and equipment during manufacturing can be greatly reduced, and the mass production efficiency can be improved, and the manufacturing cost of the stainless steel screen printing plate can be reduced.

Description

technical field [0001] The invention relates to the technical field of screen printing, more specifically, it relates to a method for making a stainless steel screen in a shielding manner. Background technique [0002] Screen printing, also known as universal printing, is used in many industries such as microelectronics, labels, touch screens, displays, circuit boards, and solar cells. There are currently two mainstream methods for screen production: [0003] The first way is photosensitive emulsion plate making method. Fix the polyester screen or stainless steel screen on a frame to form a screen screen, and then coat the photosensitive emulsion on the screen screen. The pattern to be printed is made into a film negative, and the film negative is fixed on the surface of the screen coated with photosensitive adhesive for ultraviolet irradiation. The photosensitive emulsion at the position where the light is irradiated undergoes a curing reaction and is fixed on the screen...

AI Technical Summary

Problems solved by technology

[0004] Its disadvantages are: the production process of screen printing screen is complicated, the dependence on the photosensitive emulsion is high, and the photosensitive emulsion is not good enough in the printing process, the solvent resistance tolerance is not large enough, and it encounters strong acid and alkali slurry or Ink, photosensitive emulsion is easy to fall off

[0006] This method has a simple process for making screen plates, and there are many materials to choose from, but it has very high requirements for laser equipment. The production of high dimensional accuracy and fine line printing templates requires a high dimensional repeatability of the mobile platform, matching picosecond or femtosecond level. Lasers, expensive equipment

At the same time, the environment of the equipment is harsh and the production efficiency is low. Taking the electrode pattern of 5 main grids and 106 auxiliary grids in the solar industry as an example, it takes more than 40 minutes to make a printing screen. A lot of equipment must be purchased for the production of batch screens.
