A kind of laser plate-making method and its equipment

Abstract

The invention relates to the field of screen printing, and discloses a laser plate-making method and equipment, which solves the technical problem of the existing screen plates that the plate film and the steel mesh need to be cut due to uneven butt joints during the processing, resulting in waste of resources. It includes the following operation steps, the plate film is bonded to the steel mesh: the plate film and the steel mesh are glued and fixed by an integrated device for gluing and bonding to obtain a screen plate; printing area processing: the screen plate is placed in the laser engraving equipment. On the screen plate carrying platform, the position of the screen plate is adjusted by translating the screen plate carrying platform, and the printable area is engraved on the plate film by laser. The stencil film and the steel mesh are aligned and bonded through an integrated device for gluing and bonding, and there is no need to cut the part of the stencil film and the steel mesh where the edges of the screen are dislocated later, saving resources.

Description

technical field [0001] The invention relates to the technical field of screen printing, in particular to a laser plate-making method and equipment thereof. Background technique [0002] Most of the existing screen production is made by exposure and development of photosensitive glue. The surface of the mesh is covered with photosensitive glue. Printability and more stable process capabilities, the exposure method can no longer meet these various needs. [0003] The Chinese patent with the publication number CN110802912A discloses a laser plate-making method, which includes the following steps: 1) fixing the plate film on the steel wire mesh of the screen plate; 2) placing the screen plate on the screen plate carrying platform of the laser engraving equipment, through Translate the screen carrying platform to adjust the position of the screen, and laser engrave the printable area on the plate film. When the plate film and the steel mesh are combined, the plate film and the ...

AI Technical Summary

Problems solved by technology

[0004] However, in the process of bonding the stencil and the steel mesh, it is necessary to apply glue to one side of the stencil or the steel mesh, and then bond the stencil and the steel mesh. However, during the bonding process, there are often The butt joint of the stencil film or steel mesh is offset, resulting in the possibility of excess edges being exposed. In order to ensure the neatness of the edge of the screen, it is necessary to cut the edge of the screen, which not only increases the cutting process , but also caused a waste of resources
