Dry ultrasonic cleaning device and cleaning method

Abstract

The invention provides a dry ultrasonic cleaning device and a cleaning method. The dry ultrasonic cleaning device comprises a shell, a pressure cavity, an air inlet channel and air exhaust units, wherein one end of the shell is provided with a sealing flange, and a connector is arranged in the sealing flange; the pressure cavity is formed in the shell, at least one ultrasonic generator is installed in the pressure cavity, and the bottom of the ultrasonic generator is provided with a spraying slit used for spraying airflow to the surface of an object to be cleaned; the air inlet channel is arranged on the upper side of the pressure cavity, the air inlet channel communicates with the ultrasonic generator, and the air inlet channel is connected with an air inlet pipe through the connector; and the air exhaust units are arranged on the two sides of the pressure cavity, and the air exhaust units are used for collecting impurities blown out from the surface of the to-be-cleaned object. According to the dry ultrasonic cleaning device, the purging and cleaning efficiency is high, the surface cleanliness of the to-be-cleaned object can be remarkably improved, and meanwhile, a large amount of impurity residues generated after the surface of the to-be-cleaned object is subjected to wet cleaning treatment are avoided.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel cleaning equipment, in particular to a dry ultrasonic cleaning device and a cleaning method. Background technique [0002] At present, wet cleaning is mostly used in the liquid crystal industry, but after the glue is applied, the wet cleaning has a destructive effect on the glue layer, which increases the reject rate; and after the friction orientation, a large amount of dust particles are generated, and it is a waste of resources to use wet cleaning. Because wet cleaning requires a lot of consumables, such as: purified water, other chemicals, etc. When spraying gaskets in the production process, due to improper spraying, it is easy to cause glass plates that do not meet the requirements. At present, these unqualified glass plates are treated as waste products, which is relatively wasteful. And wet cleaning can only clean the surface, which often fails to achieve the desired effect. ...

Problems solved by technology

[0002] At present, wet cleaning is mostly used in the liquid crystal industry, but after the glue is applied, the wet cleaning has a destructive effect on the glue layer, which increases the reject rate; and after the friction orientation, a large amount of dust particles are generated, and it is a waste of resources to use wet cleaning. Because wet cleaning requires a lot of consumables, such as: pure water, other chemicals, etc.

When spraying gaskets in the production process, due to improper spraying, it is easy to cause glass plates that do not meet the requirements. At present, these unqualified glass plates are treated as waste products, which is more wasteful.

Moreover, wet cleaning can only clean the surface, which often fails to achieve the desired effect.
