Embodiment 1

[0053] Reference attached figure 1, the glass substrate cleaning method provided in the embodiment of the present application, the cleaning environment where it is located requires that the ambient pressure is 10pa-15pa higher than the atmospheric pressure, the cleanliness is 2000-5000, and the cleanliness is in accordance with the "Code for Design of Clean Workshops" GB50073-2001 standard; The glass substrate cleaning method that embodiment provides comprises the following steps:

[0054] 101. Preliminary cleaning of the glass substrate;

[0055] Specifically, the glass substrate enters the cleaning process after the edging process. In this step, the glass substrate is preliminarily cleaned by washing with water, so that the grinding powder brought by the edging process and larger particles or impurities on the surface of the glass substrate can be removed;

[0056] Among them, the method of preliminary cleaning can be one or more of methods such as high-pressure spraying an...

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...
