High-precision single-pass double-sheet automatic screen printing machine

Abstract

The invention relates to the technical field of screen printing. A high-precision fully-automatic screen printing machine capable of printing double pieces in one process abuts on a semi-automatic screen printing machine and comprises a rack, a conveying line assembly, a supplying-receiving disc assembly and feeding mechanisms, wherein the conveying line assembly is located on the rack; the supplying-receiving disc assembly is located on a transport surface of the conveying line assembly and capable of being driven to move by the conveying line assembly, and a plurality of printing stocks placed in pairs are arranged in the supplying-receiving disc assembly; and the feeding mechanisms are located between the conveying line assembly and the semi-automatic screen printing machine, grab the printing stocks in the supplying-receiving disc assembly in pairs, and transport the printing stocks to a printing surface of the automatic screen printing machine. According to the high-precision fully-automatic screen printing machine capable of printing double pieces in one process, which is disclosed by the invention, an ingenious double-piece taking mechanism, an accurate one-process double-piece location mechanism and a precise double-piece loading mechanism are designed, so that the printing accuracy can be increased, and the screen printing efficiency can be doubled on the basis of increasing a small amount of cost for a single-piece semi-automatic transformed screen printing machine.

Description

technical field [0001] The invention relates to the technical field of screen printing, and more specifically, to upgrading equipment for screen printing machines. Background technique [0002] With the increasing maturity and development of automatic screen printing technology and the gradual expansion of the industrial scale, the application field of automatic screen printing technology is constantly expanding. At present, the automatic screen printing machine focuses on the high-precision printing of hard materials, such as the printing of window glass, industrial glass, PMMA, OGS, TOL, etc. Its main application fields are: IT window glass, industrial glass, solar silicon Batteries, PCB circuit boards, LCD screens, touch panels and various touch screens. Fully automatic screen printing technology uses more advanced processing technology and technology to make the screen printing process more accurate, faster and more automated. [0003] The present invention is a high-p...

AI Technical Summary

Problems solved by technology

At present, the existing single-chip semi-automatic transformation screen printing machine needs to transform the printing platform of the customer's semi-automatic screen printing machine, that is, the printing platform is transformed into an eight-column secondary fine positioning mechanism, and when the screen printing screen is broken, the ink will flow into the fine positioning In the mechanism, it is difficult to clean the ink in the mechanism, which affects the positioning accuracy, and the printing accuracy can only reach ±0.05mm; in addition, the efficiency of the existing single-chip semi-automatic screen printing machine is relatively low, and a pre-positioning is required before printing. Carry out fine positioning again before printing, and only one piece can be printed at a time, and the efficiency is generally around 600 pieces / hour

[0004] The existing problems and shortcomings of the existing single-chip semi-automatic transformation screen printing machine: it is necessary to pull out the customer's screen printing machine in advance to carry out the printing platform transformation, which will affect the customer's production; after the screen plate is damaged, the ink will pollute the mechanism, which is inconvenient to maintain; the printing accuracy is low and low efficiency

[0005] In addition, the existing material tray basically puts two pieces of substrates in a row, divided into four or five rows, and places a total of 8 or 10 pieces. If the substrates in the first row and the second row are taken vertically at the same time, There will be situations where the fifth row cannot be retrieved
