Screen printing machine based on microcomputer control

Abstract

The invention relates to the technical field of screen printing equipment, and discloses a screen printing machine based on microcomputer control. The screen printing machine comprises a bottom track,wherein a bearing platform is fixedly installed at the top of the bottom track, and a movement platform is movably installed at the portion, located at the right side of the bearing platform, of thetop of the bottom track. According to the screen printing machine based on microcomputer control, through the cooperation of a miniature gear motor, a pinion and an internal gear ring, when a screen printing plate needs to be replaced, the corresponding screen printing plate can be directly rotated to the position over a workbench, thus the screen printing plate can be replaced in the working process, and the time spent in detaching the original screen printing plate and replacing the original screen printing plate with a new one can be saved; and besides, when all screen printing plates needto be replaced, the screen printing plates can be unifiedly replaced at the non-production time, and therefore, the process of conducting repeated replacement on one screen printing plate base is omitted.

Description

technical field [0001] The invention relates to the technical field of screen printing equipment, in particular to a screen printing machine based on microcomputer control. Background technique [0002] Screen printing belongs to stencil printing, and it is called the four major printing methods together with lithography, embossing, and gravure printing. Stencil printing includes transcription, perforated pattern, inkjet and screen printing, etc. The principle of stencil printing is : The printing plate (the hole that can pass the ink is made on the base of the paper film plate or other plates) when printing, the ink is transferred to the substrate (paper, ceramics, etc.) through the holes of the stencil through a certain pressure to form a pattern It can also be used in the electronic processing industry to print solder paste or patch glue on the PCB pad through the screen. [0003] During the use of the current screen printing machine, the screen printing plate can be rep...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a screen printing machine based on microcomputer control, which can automatically replace the scraper and the screen printing plate, and the positioning is more accurate when replacing the scraper and the screen printing plate, and the processing efficiency can be increased. The advantage of automatically loading and unloading substrates to reduce the productivity of defective products solves the problems mentioned in the above background technology
