A dust removal device for liquid crystal module display screen during processing

Abstract

The invention discloses a dust removal device in the process of processing a liquid crystal module display, which includes a dust removal pipe, a deflector, a filter assembly and an air distribution pipe. The inner walls of both sides of the dust removal pipe are fixed with deflectors by welding, the top of the dust removal pipe is connected with a gas distribution pipe through a flange, the inner wall of the dust removal pipe is provided with a filter assembly, and one side of the dust removal pipe is provided with a The dust treatment device, the air distribution pipe is funnel-shaped, and a blower is connected through the top of the air distribution pipe, and the inside of the air distribution pipe is uniformly provided with a partition plate, and the partition plate divides the inside of the air distribution pipe into four gas flow channels, Each gas channel is respectively provided with a first throttle valve and a gas flow sensor, the filter assembly includes a HEPA air filter, the bottom of the HEPA air filter is in contact with the deflector, and the present invention has a good dust removal effect and easy cleaning and maintenance features.

Description

technical field [0001] The invention relates to the technical field of liquid crystal module processing, in particular to a dust removal device during the processing of liquid crystal module display screens. Background technique [0002] Liquid crystal glass is a high-tech optoelectronic glass product made by encapsulating liquid crystal film through high temperature and high pressure. In the production process of liquid crystal glass, the dust on the glass substrate will have a great impact on product performance, so after the glass substrate cutting process, it is necessary to remove the dust on the glass substrate. [0003] The existing dust removal method usually aligns the centrifugal dust collection device with the liquid crystal panel to absorb the dust on it. Although it can achieve the dust removal effect, there is a small amount of dust stuck on the panel that cannot be removed; the existing dust removal device needs to clean the dust recovery system. It is time-c...

[0003] The existing dust removal method usually aligns the centrifugal dust collection device with the liquid crystal panel to absorb the dust on it. Although it can achieve the dust removal effect, there is a small amount of dust stuck on the panel that cannot be removed; the existing dust removal device needs to clean the dust recovery system. It is time-consuming and labor-intensive to disassemble the entire shell and clean the filter screen or filter; at the same time, because the LCD panel is wide, the dust removal device is often designed to be wide, and the internal air is easy to form convection when it is passed in, resulting in a small air flow on both sides and a dust removal effect. uneven
