Description

TECHNICAL FIELD

[0001] The utility model relates to LCD glass substrate cleaning technical field, specifically point to a kind of defogging mechanism for glass substrate cleaning equipment, it is mainly used to remove the splash water mist generated in the process of cleaning, drying and blowing of LCD glass substrate, to assist to improve the cleaning effect of LCD glass substrate. BACKGROUND

[0002] ‌LCD glass substrate‌ is a basic component of liquid crystal display device, is a kind of extremely flat surface float glass production thin glass sheet. It is the core component of liquid crystal display panel, and is crucial to electronic information display industry.

[0003] In the preparation process of liquid crystal display device, first, the corresponding LCD glass substrate needs to be cleaned, dried and pretreated. To prevent the dirt washed away from reattaching to the surface of the LCD glass substrate, some manufacturers directly tilt the drying air knife on both sides of the cleaning nozzle to control the cleaning water splashed on the LCD glass substrate within a narrow range, so that the cleaning water is quickly discharged along the two sides after completing the cleaning of the LCD glass substrate, thereby preventing the dirt washed away from reattaching to the surface of the LCD glass substrate. However, since the air knife forms an air curtain on both sides of the cleaning water splashed on the LCD glass substrate, and the cleaning water is also prone to splash when washing the LCD glass substrate, even if the width of the cleaning water is isolated within a small range, some dirt will also bounce back to the surface of the LCD glass substrate with the splashed water, thereby causing the dirt to reattach to the surface of the LCD glass substrate.

[0004] Therefore, a device is designed to effectively and timely absorb the splash water mist generated during cleaning and drying, and effectively remove the absorbed cleaning wastewater in time, thereby effectively preventing dirt from reattaching to the surface of the LCD glass substrate, to

[0005] The existing cleaning equipment for LCD glass substrate processing mainly includes a material conveying mechanism and a isolation cover arranged on the upper side of the material conveying mechanism. The material conveying mechanism is provided with a leaching mechanism and an air knife mechanism arranged in front and back of the material conveying mechanism to perform leaching and drying operations on the LCD glass substrate respectively. The dried LCD glass substrate is then conveyed into a corresponding drying equipment for drying treatment, thereby completing the pretreatment of the material. During the leaching process, the dirt washed away is easily left in the water, thereby causing the dirt to easily reattach to the surface of the LCD glass substrate. When the air knife cleans the water, some of the dirt reattached to the surface of the LCD glass substrate cannot be removed in time, thereby causing the cleaning effect to fail to meet the design requirements, which is unacceptable for the extremely high surface cleanliness requirement of the LCD glass substrate.

[0006] Therefore, the utility model discloses a kind of fog removal mechanisms for glass substrate cleaning equipment, which can effectively prevent the dirt washed away from re-attachment to the surface of LCD glass substrate, thereby improving the cleaning effect of LCD glass substrate. SUMMARY
