Abstract

The invention discloses a glass substrate cleaning method and cleaning equipment. The glass substrate cleaning method comprises the following steps: preliminarily cleaning a glass substrate; blowing the glass substrate for the first time; cleaning the glass substrate by a disc brush; blowing the glass substrate for the second time; backwashing and drying the glass substrate; and removing static electricity from the glass substrate. The glass substrate is primarily cleaned, and disc brush cleaning is performed after primary blowing, so that particles and impurities on the surface of the glass substrate are primarily removed, and the situation that the particles and the impurities are brought into a disc brush cleaning process to scratch the surface of the glass substrate is avoided; meanwhile, after the disc brush is used for cleaning, the glass substrate is subjected to secondary purging and then is subjected to back washing and drying, so that the cleanliness of the surface of the glass substrate is further guaranteed, the cleaning effect is guaranteed, and the situation that the subsequent process is affected by a residual cleaning agent in the disc brush cleaning process is avoided; and moreover, the arrangement of static electricity removal can prevent the glass substrate from adsorbing impurities, so that the cleaning effect of the glass substrate is improved again.

Description

technical field [0001] The present application relates to the technical field of glass production, in particular to a glass substrate cleaning method and cleaning equipment. Background technique [0002] The glass substrate is one of the important raw materials of the display panel. The cleaning degree of the glass surface will have a certain influence on the display effect of the subsequent products, and the display products have strict requirements on the number of particles and surface defects on the surface of the glass substrate. Before the production of display products, it is necessary to clean the surface of the glass substrate. High particles or many surface defects will cause the film layer to fall off, disconnection and other defects in the panel factory, which will affect the yield rate of the panel factory. [0003] At present, the cleaning method of glass substrates is simple, which cannot guarantee a high degree of cleanliness on the surface of glass substrate...
