Cleaning brush roller used in TFT-LCD display screen production and manufacturing method thereof

Abstract

The invention discloses a cleaning brush roller used in TFT-LCD display screen production and a manufacturing method thereof. The cleaning brush roller comprises a brush shaft and a brush sleeve, the brush shaft comprises a middle shaft body, the middle shaft body is a double-layer structure, the outer layer of the middle shaft body is a thin-walled tube body structure, a carbon fiber tube is embedded in the inner wall of the thin-walled tube body, and the carbon fiber tube is embedded in the inner wall of the thin-walled tube body in a seamless mode. End fixing shafts are installed at the two ends of the thin-walled tube body, the brush sleeve comprises a brush belt, superfine brush wires are irregularly woven on the brush belt, the superfine brush wires are woven on the belt through a weaving machine, the weaving density of the superfine brush wires requires that about ten thousand bristles are evenly distributed in one square meter, the woven brush belt is fixed to the sleeve, and the brush sleeve is arranged on the middle shaft body in an extruding and sleeving mode. The structure that the thin-walled tube body and the carbon fiber tube are combined and the superfine brush wires are woven on the brush belt is adopted, the strength of the brush shaft is guaranteed, meanwhile, the overall weight of the brush roller is reduced, the swing amount of the brush roller in the using process is reduced, and the cleaning quality is improved through dense distribution of the superfine brush wires.

Description

Technical field: [0001] The invention relates to the field of brush roller structures, and mainly relates to a cleaning brush roller used in the production of TFT-LCD display screens and a manufacturing method thereof. Background technique: [0002] During the production process of the TFT-LCD display screen, its surface needs to be cleaned. Since the thickness of the display screen is relatively thin at about 0.2mm, if a cleaning brush roller with a traditional structure is used, its relative weight is about 100 kg. Too heavy, because the brush roller is relatively thin, so in the process of high-speed cleaning, there will be a certain sag, which will cause the glass display screen to break, which will cause serious losses and affect its production efficiency. [0003] In the traditional cleaning brush structure, the distribution of the bristles is fixed by the metal. During the cleaning process, the metal will rust for a long time, and sometimes powder will be added, which...

Problems solved by technology

[0002] During the production process of the TFT-LCD display screen, its surface needs to be cleaned. Since the thickness of the display screen is relatively thin at about 0.2mm, if a cleaning brush roller with a traditional structure is used, its relative weight is about 100 kg. Too heavy, because the brush roller is relatively thin, so in the process of high-speed cleaning, it will produce a certain degree of sag, which will cause the glass display screen to break, which will cause serious losses and affect its production efficiency.

[0003] In the traditional cleaning brush structure, the distribution of the bristles is fixed by the metal. During the cleaning process, the metal will rust for a long time, and sometimes powder will be added, which will pollute the product and affect the cleaning effect of the product. There is a certain gap in the distribution density of the bristles, so that there will be blind spots during cleaning. The general standard is that the dust particles per square meter should be within 30. However, the traditional bristles are fixed by metal, and the display screen after cleaning passes through Ultraviolet detection equipment detects that there will be more than 30 dust particles per square meter, which cannot meet the cleaning accuracy requirements
