Screen plate repairing table with laser indicator

Abstract

The invention discloses a screen plate repairing table with a laser indicator. The screen plate repairing table comprises a machine frame, a screen plate nested in a positioning table, a control unitfor controlling the operation of the screen plate repairing table, a code scanning device for identifying the identity codes of the screen plate, a laser marking device controlled by the control unitto complete the defect one-by-one positioning on the screen plate and a microscopic device used for assisting workers to repair the screen plate. According to the screen plate repairing table, according to the structure, the defects in the screen plate repairing process can be rapidly and accurately positioned, so that the working efficiency of workers is improved, and meanwhile, the working intensity of workers is reduced.

Description

Technical field [0001] The invention relates to the field of screen printing, in particular to a screen repair table with a laser pointer. Background technique [0002] Screen printing refers to the use of silk screen as a plate base, and through the photosensitive plate making method, made into a screen with graphics and text. Screen printing is composed of five major elements, screen, squeegee, ink, printing table and substrate. Use the basic principle that the mesh of the graphic part of the screen can penetrate the ink, and the mesh of the non-graphic part cannot penetrate the ink for printing. When printing, pour ink on one end of the screen, use a squeegee to apply a certain pressure to the ink part on the screen, and at the same time move to the other end of the screen at a uniform speed. The ink is squeezed from the mesh of the graphic part by the squeegee during the movement. Press onto the substrate. However, in this printing process, the screen in the screen is ofte...

AI Technical Summary

Problems solved by technology

However, the existing non-adhesive marking method often has the problem that the marking range of the defect is too large. When the workers repair the screen, they need to go through a long search to find the exact defect position on the screen, and the labor intensity of the workers is relatively high. and inefficient
