Tank cleaning device

Abstract

The invention relates to common wet-type equipment in liquid crystal display manufacture procedures, and provides a device for washing a water tank. A circulation path of washing liquid in the water tank is formed through a water inlet pipe, a spraying knife and a water plugging opening. When the device is used, a pressure regulator is used for injecting the washing liquid into the circulation path, fluid pressure in the circulation path is kept through the water plugging opening, the washing liquid having certain pressure is finally sprayed out from inside to outside from a seam in the spraying knife, a pressure water curtain is formed to wash the inner wall of the water tank, a wrench fixedly connected with the water plugging opening is used in an assisted manner to rotate the spraying knife by 360 degrees from the exterior of the water tank, and all-dimensional washing of the interior of the water tank is finally achieved. The cleaning effect of the pressure water curtain on the inner wall of the water tank exceeds the effect of manual wiping or simple washing, the repeated demounting and mounting process of a water tank cover plate during conventional washing is avoided, the washing procedure is simplified, and the washing quality is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display manufacturing, in particular to wet equipment in the liquid crystal display manufacturing process. Background technique [0002] In the manufacturing process of display devices, the application of wet equipment (Wet equipment) is very common, such as cleaning machines (Cleaner) used to remove impurities (Particle) and organic matter on the surface of the substrate before coating the glass substrate, or for glass substrates After the coating is exposed, the photoresist is stripped to form a developer (Develop) of the desired pattern (pattern). The water tank of wet equipment is an important part for storing cleaning fluid or buffering water for cleaning. The excellent design of the water tank directly affects the performance and product yield of the wet equipment. [0003] The water tank part of the wet equipment is generally arranged on the lower side of the wet equipment, and is composed of...

Problems solved by technology

[0004] However, most of the closed water tanks that have been used for a long time will accumulate dirt, scale or water quality prone to bacteria, and the inside of the water tank needs to be cleaned regularly

Due to the position of the water tank of most wet equipment, it is troublesome to disassemble the water tank and clean the inner wall every time, and the steps of dismantling and resetting the water tank cover are more complicated, and the requirements for the operator are also high, and it is easy to be careless cause the tank to leak

On the other hand, cleaning methods such as wiping or rinsing are difficult to ensure that the cleanliness of the water tank meets the requirements for use
