Linear flowing exposure device for printing screen plate

Abstract

The invention relates to a linear flowing exposure device for a printing screen plate. The device comprises an exposure rack, wherein an exposure table is arranged on the exposure rack, a driven roller is arranged on one side of the exposure rack, a driving roller is arranged on the other side of the exposure rack, a conveying aluminum belt is arranged between the driving roller and the driven roller, and the conveying aluminum belt is mounted above the exposure table. A stepping motor is arranged in a lateral position of the exposure rack, a driving shaft is arranged on the front part of thestepping motor, and the driving shaft is mounted in an axial position of the driving roller. A moving plate is arranged on the lower part of the conveying aluminum belt, the moving plate is mounted above the exposure table, and an ultraviolet lamp exposure mechanism and an electric heating melting mechanism are arranged on the bottom surface of the moving plate. A power supply and a temperature controller are arranged on the top of the exposure rack, the ultraviolet lamp exposure mechanism comprises a lamp shell, an ultraviolet lamp tube is mounted in the lamp shell, and the ultraviolet lamp tube is connected to the power supply through a first cable. The device carries out centralized exposure to a to-be-exposed part on the printing screen plate, so that the exposure efficiency is improved greatly.

Description

technical field [0001] The invention relates to an optical device, in particular to a linear flow exposure device for a printing screen printing plate. Background technique [0002] Screen printing consists of five major elements, namely screen printing plate, squeegee, ink, printing table and substrate. The basic principle of screen printing is: use the basic principle of the screen printing plate's graphic part of the mesh to penetrate ink, and the non-graphic part of the mesh to be impermeable to ink. When printing, pour ink into one end of the screen printing plate, apply a certain amount of pressure on the ink part of the screen printing plate with the scraper, and at the same time, print towards the other end of the screen printing plate. The ink is squeezed by the scraper from the mesh of the graphic part to the substrate during the movement. Due to the viscosity of the ink, the imprint is fixed within a certain range. During the printing process, the scraper is alw...

AI Technical Summary

Problems solved by technology

The positioning and installation of the existing printing screen printing plate is inaccurate, it is inconvenient to perform exposure operation on the printing screen printing plate, and the efficiency of centralized exposure to the local exposure parts on the printing screen is low
