Device and method for cleaning glass substrate

Abstract

The invention provides a device for cleaning a glass substrate. The device comprises a pressure pump, a CO2 storage tank, a CO2 foam generator and a nozzle pipeline, wherein a water inlet of the pressure pump is communicated with a water source; a water outlet of the pressure pump is divided into two paths, one path is communicated with a water inlet of the CO2 foam generator, and the other path is communicated with an inlet of the nozzle pipeline after combined with an outlet of the CO2 foam generator through a pipeline; a CO2 inlet of the CO2 foam generator is communicated with an outlet of the CO2 storage tank through a pipeline; and a plurality of nozzles are arranged on the pipe wall of the nozzle pipeline. With the adoption of the device, the glass substrate can be cleaned quickly.

Description

technical field [0001] The invention belongs to the field of flat glass manufacturing, and in particular relates to a device and method for cleaning substrate glass. Background technique [0002] During the manufacturing process of liquid crystal substrate glass, some Particles (dust particles and other sundries) are often attached to the surface of the glass substrate. These sundries attached to the glass substrate directly affect the quality of the glass and have a great impact on the client's further production of display devices. Therefore, glass substrate manufacturers will clean the glass after cutting, generally including dish brush, roller brush, ultrasonic cleaning, liquid medicine cleaning and other cleaning methods, but these cleaning methods sometimes scratch the glass, and at the same time not safe. [0003] The friction between the glass substrate and the air during the production and transmission process will cause a strong electrostatic voltage on the glass ...

Therefore, glass substrate manufacturers will clean the glass after cutting, generally including dish brush, roller brush, ultrasonic cleaning, liquid medicine cleaning and other cleaning methods, but these cleaning methods sometimes scratch the glass, and at the same time unsafe

[0003] The friction between the glass substrate and the air during the production and transmission process will cause a strong electrostatic voltage on the glass substrate, so some dust particles in the air and glass powder particles generated by glass cutting are adsorbed on the glass surface by the static electricity on the glass, cleaning it's very difficult
