Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, and particularly relates to a glass substrate pre-wetting cleaning equipment. BACKGROUND

[0002] The glass substrate is a basic component material of the liquid crystal panel, and the cleanliness thereof has a crucial influence on the whole process of the liquid crystal panel. With the continuous improvement of the liquid crystal panel technology, the display imaging resolution is also continuously improved, and the process of the panel has a more stringent requirement on the cleanliness of the glass substrate. In the production process of the glass substrate, in order to achieve the length and width dimensions specified by the customer, each glass substrate needs to be segmented by special means, and the number and size of the particles on the surface of the glass substrate are also an important control index. The glass substrate can only reach a high degree of cleanliness after being ground. After the glass substrate is segmented and ground, a large amount of dust is left on the surface of the glass substrate, so that the glass substrate needs to enter the cleaning area and be cleaned by the cleaning equipment.

[0003] At present, in order to improve the cleaning effect of the glass substrate, the surface of the glass substrate is pre-wetted. The common way of pre-wetting the surface of the glass substrate is to directly spray water on the surface of the glass substrate through a spray pipe. However, this method has the following defects in actual use:

[0004] When the glass substrate is cleaned by the cleaning equipment, the glass substrate is generally horizontally conveyed, so that the glass substrate is displaced to the liquid medicine spraying assembly, the roller brush cleaning assembly, the water-washing roller brush cleaning mechanism, the flushing mechanism and the air-drying mechanism of the cleaning equipment in turn. The glass substrate is cleaned and flushed by the liquid medicine spraying assembly, the roller brush cleaning assembly, the water-washing roller brush cleaning mechanism and the flushing mechanism in turn, and then is air-dried by the air-drying mechanism to complete the cleaning work of the glass substrate. However, during the pre-wetting of the glass substrate, since the glass substrate is horizontally conveyed, it is difficult to pre-clean the dust on the top of the glass substrate when the spray pipe sprays water on the top of the glass substrate for pre-wetting, thereby increasing the cleaning difficulty of the glass substrate by the subsequent roller brush cleaning assembly and reducing the cleaning efficiency.

[0005] Therefore, the present application provides a glass substrate pre-wetting cleaning equipment. SUMMARY
