Liquid crystal glass substrate cleaning device and method

Abstract

The invention relates to the field of liquid crystal glass substrates, and discloses a liquid crystal glass substrate cleaning device and method. The liquid crystal glass substrate cleaning device comprises a cleaning fluid cleaning unit, a front isolation unit and a rear isolation unit, wherein the front isolation unit and the rear isolation unit are respectively connected to the head end and the tail end of the cleaning fluid cleaning unit; each of the front isolation unit and the rear isolation unit comprises a fluid cutter part which is close to one side of the cleaning fluid cleaning unit; and the fluid cutter parts respectively spray cleaning fluid to the cleaning fluid cleaning unit obliquely so as to form a cleaning fluid curtain extending in the width direction of the liquid crystal glass substrate cleaning device. The liquid crystal glass substrate cleaning method comprises the step of cleaning the liquid crystal glass substrate by using the liquid crystal glass substrate cleaning device, wherein the cleaning fluid is a hydrochloric acid solution. In the liquid crystal glass substrate cleaning device, the cleaning fluid cleaning unit is well isolated from front and back relevant working procedure units. By the method disclosed by the invention, the good cleaning effect can be achieved.

Description

technical field [0001] The invention relates to the field of liquid crystal glass, in particular to a liquid crystal glass substrate cleaning device and method. Background technique [0002] As a method of manufacturing glass substrates used in liquid crystal displays, there is known a manufacturing method called float forming, and the manufacturing method roughly includes the following steps: forming process, that is, forming a ribbon-shaped glass substrate; cutting / chamfering / grinding The process is to cut the above-mentioned ribbon-shaped glass substrate into rectangular glass substrates of a predetermined size that meet the requirements; the cleaning process is to remove foreign matter on the glass surface; and the inspection and packaging processes, etc. [0003] Wherein, the cleaning process is completed using liquid crystal glass substrate cleaning equipment to remove contamination and particles on the surface of the glass substrate. Most of the current liquid crysta...

Problems solved by technology

However, the problem is that, due to the insufficient cleaning power of the alkaline cleaning solution, most of the stains and particles on the surface of the glass substrate can be removed by using the alkaline cleaning solution, but the foreign matter adhered to the glass substrate when it is formed in the kiln tin bath annealing furnace Or surface drops, such as tin spots, are difficult to remove, which makes the circuit on the panel short-circuited and affects the quality of the finished product when using a glass substrate to make a display; however, if using hydrochloric acid solution and other equipment with high cleaning strength, Due to strong corrosion, higher protection measures are required, and the existing liquid crystal glass substrate cleaning equipment cannot meet this requirement due to structural limitations.
