Cleaning method of glass substrate and device for implementing method

Abstract

The invention provides a cleaning method of a substrate and a device for implementing the method. The method comprises the following steps of: step 1, providing a conveying platform (20) and a glass substrate (40) to be cleaned; step 2, placing the glass substrate (40) to be cleaned on the conveying platform (20); step 3, providing two air blowing devices (60); step 4, blowing air to the glass substrate (40) to be cleaned by the two air blowing devices (60), so that impurities (42) adhered to the glass substrate (40) to be cleaned are removed from the glass substrate (40); step 5, providing an adsorption device (80) comprising an air absorption device (82) and a magnetic absorption device (84); and step 6, absorbing air for the glass substrate (40) to be cleaned by the air absorption device (82), and generating a magnetic absorption force to the magnetic impurities on the glass substrate (40) to be cleaned by the magnetic absorption device (84), thereby absorbing the impurities (42) on the glass substrate (40) to be cleaned into the adsorption device (80).

Description

technical field [0001] The invention relates to a cleaning method, in particular to a cleaning method of a glass substrate and a device for realizing the method. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules in two parallel glass substrates, control the liquid crystal molecules to change direction by energizing the circuit of the glass substrates, and refract the light from the backlight module to produce a picture. [0003] During the manufacturing process of the liquid crystal display panel, there are often impurities remaining on the glass substrate, resulting in defects...
