Description

Silk screen printing equipment and battery piece system of processing

Technical Field

The utility model relates to a battery piece processing technology field especially relates to a silk screen printing equipment and battery piece system of processing.

Background

An important process in the processing procedure of the battery piece during the screen printing is mainly applied to the electrode forming of the battery, and the basic principle that the meshes of the screen pattern part are penetrated with the slurry and the meshes of the non-image-text part are not penetrated with the slurry is utilized for printing. During printing, slurry is poured into one end of the silk screen, a scraper is used for applying certain pressure on the slurry part of the silk screen, and the scraper moves towards the other end of the silk screen. The slurry is pressed from the meshes of the pattern portion onto the substrate by the squeegee while moving. The scraper blade is line contact with the silk screen printing plate and the printing stock all the time in the printing process, the contact line moves along with the movement of the scraper blade, and other parts of the silk screen are separated from the printing stock, so that the printing size precision is ensured and the smearing of the printing stock is avoided. When the scraper blade is lifted after scraping the whole printing area, the silk screen is also separated from the substrate, the slurry is slightly scraped back to the initial position by the ink returning blade, and the workbench returns to the loading position, so that the printing stroke is complete.

In the printing process, due to the fact that the printing machine is in an open environment, the yield and the quality of the printed battery piece can be affected by various external factors such as temperature, humidity, dust in air, particulate matters and the like in a printing workshop. Particularly, because the printing workshop space is big, and temperature, humidity are difficult to fine control, lead to organic solvent to volatilize too fast in the silver thick liquid, and the grid line quality of printing out descends, need shut down to add the silver thick liquid diluent and promote printing quality, have influenced the printing productivity greatly. The silver powder in the silver paste is 3-5 microns in size, the requirement on the precision of a screen printing plate used for printing is high, and dust and particulate matters in the air can easily fall into the silver paste in an open printing machine environment. On one hand, the electrical property of the silver paste is deteriorated, the ohmic contact between the silver paste and the battery piece is influenced, and the efficiency of the battery piece is lowered; on the other hand, existence of dust and particulate matter can cause the half tone stifled hole, leads to the printing to appear disconnected bars phenomenon, handles stifled hole and needs a large amount of time, very big influence the printing productivity.
