Silk printing static electricity removing device and application method thereof

Abstract

The invention discloses a silk printing static electricity removing device and an application method thereof in the technical field of silk screen printing. The device comprises an aluminum alloy cross beam mounted on a frame; a left side cylinder and a right side cylinder are mounted on the left and right sides of the bottom of the aluminum alloy cross beam; intake ports and exhaust ports of theleft side cylinder and the right side cylinder are connected with electromagnetic valves through air pipes; leads are connected with a first time relay and a second time relay; an output end of the left side cylinder is connected with the left end of a stainless steel silica gel roller; and a bottom output end of the right side cylinder is connected with the right end of the stainless steel silicagel roller. The device solves the prevention and release problems of static electricity generated in the silk printing process by using the characteristics of electric conductivity of water and generation of no static electricity during striping between water and water, so that the damage to product devices and electrodes by discharge of the static electricity is effectively prevented; and through automatic induction water coating, the labor intensity of manual water coating is greatly relieved, the automation is realized, and the labor cost is saved.

Description

technical field [0001] The invention discloses a screen printing static electricity removal device and a method for using the same, in particular to the technical field of screen printing. Background technique [0002] Usually static electricity is generated by frictional electrification. In essence, frictional electrification is a process of contact and separation that causes the imbalance of positive and negative charges. Silk screen printing is a friction between the scraper and the screen, the screen and the substrate, and the continuous contact In the process of separation, the amount of static electricity generated is very large, and the electrostatic voltage even reaches an astonishing 20KV. Under such a high voltage, electrostatic discharge is very easy to occur, resulting in breakdown and damage of components and electrodes, resulting in serious product defects. For example, the harm it causes to the LCD screen printing process is mainly due to the breakdown of the ...

[0002] Usually static electricity is generated by frictional electrification. In essence, frictional electrification is a process of contact and separation that causes the imbalance of positive and negative charges. Silk screen printing is a friction between the scraper and the screen, the screen and the substrate, and the continuous contact In the process of separation, the amount of static electricity generated by it is very large, and the electrostatic voltage even reaches an astonishing 20KV. Under such a high voltage, electrostatic discharge is very easy to occur, resulting in breakdown and damage of components and electrodes, resulting in serious product defects. For example, the harm it causes to the LCD screen printing process is mainly due to the breakdown of the PI layer and the loss of orientation caused by electrostatic discharge, which manifests as dense dot-like defects. Waste and static electricity have always been the focus of screen printing enterprises' control
