Scraping strip adjustment mechanism for coating machine and coating machine

Abstract

The embodiment of the invention discloses a scraping strip adjustment mechanism for a coating machine. The scraping strip adjustment mechanism comprises a base support, an upper plate and a lower plate. The two ends of the upper plate and the two ends of the lower plate are fixed to the base support. One side of a scraping strip is clamped by the upper plate and the lower plate, and the other sideof the scraping strip is close to the surface of a rolling shaft of the coating machine. The upper side of the upper plate further comprises an adjustment plate. The two ends of the adjustment plateare fixed to the base support. The adjustment plate is provided with multiple adjustment devices, and the adjustment devices are used for adjusting the spacing distance between the adjustment plate and the upper plate. The invention further discloses the corresponding coating machine. By means of the scraping strip adjustment mechanism for the coating machine and the coating machine, the distancebetween the scraping strip and the rolling shaft can be adjusted conveniently, and maintenance efficiency and production efficiency of the coating machine can be improved.

Description

technical field [0001] The invention relates to the display field, in particular to a scraper adjusting structure for a coating machine and the coating machine. Background technique [0002] At present, liquid crystal display devices have been widely used in various electronic products as display components of electronic equipment. The coating and development process is an important part of defining microelectronic circuit patterns in the production of liquid crystal display devices. In the actual production process of the device used for linear coating of photoresist, it is necessary to spray the coating on the roller (Roller) with a scraper (Blade). ) The excess photoresist on the surface is scraped off. But in the actual process, as the use time increases, the adhesion between the scraper and the roller will gradually deteriorate, and then there will be bright lines (LC Dummy Roller bright lines) on the LCD, which will cause The abnormality of uneven light occurs in liq...

Problems solved by technology

But in the actual process, as the use time increases, the adhesion between the scraper and the roller will gradually deteriorate, and then there will be bright lines (LC Dummy Roller bright lines) on the LCD, which will cause The liquid crystal product has abnormal light unevenness. When this happens, it is necessary to readjust the position of the scraper or replace the scraper. However, in the prior art, it is time-consuming and laborious to adjust the position of the scraper or replace the scraper.
