Description

Lightweight panel cleaning brush

The present invention relates to a lightweight panel cleaning brush, and more particularly to a cleaning brush for cleaning a liquid crystal panel or cleaning a glass substrate used to make a liquid crystal panel.

Before the LCD panel is shipped from the factory, the dust on the panel must be cleaned through the panel cleaning brush. And because the liquid crystal panel is cut from a large piece of glass during the manufacturing process. For example, the 7.5-generation glass substrate has a length and width of 225 cm and 195 cm, respectively, and the 8.5-generation glass substrate has a length and width of 250 cm and 220 cm, respectively, and a thickness of less than 1 mm. Therefore, the manufacture, transportation and cleaning of such glass substrates require a relatively high technical threshold.

As the size of the glass substrate and the liquid crystal panel is increasing, the brush required for cleaning such a glass substrate and a liquid crystal panel must also be improved. The brush used to clean the surface of a glass substrate or a liquid crystal panel is made of stainless steel. However, the specific gravity of stainless steel is high. Therefore, when the rotating shaft of the brush is as long as 220 cm, the center and the two ends may not be in the same straight line. On the line, when the brush is rotated and brushed, the brushing force will be uneven. In addition, when the brush rotates at a high speed, due to the bending deformation of the rotating shaft, an eccentric shock will occur, resulting in a possibility of generating a large noise during brushing and a large shaft wear.

In summary, the conventional brush for cleaning a liquid crystal panel or a large-sized glass substrate and the rotating shaft thereof have uneven brushing force, and are susceptible to vibration and noise when rotating at a high speed.

A lightweight panel cleaning brush whose main purpose is to improve the problem that a general cleaning brush is susceptible to vibration and shaking during brushing.

The brush is placed on the outer surface of the lightweight outer tube. The first stainless steel end piece is coupled to the rotating shaft structure and covers the lightweight outer tube and one end of the carbon fiber inner tube. The second stainless steel end piece is coupled to the rotating shaft structure and covers the light outer tube and the other end of the carbon fiber inner tube.

Therefore, in this case, the carbon fiber inner tube and the light outer tube are coaxially passed through the sleeve to form a rotating shaft structure to reduce the overall weight, and the carbon fiber inner tube is disposed in the light outer tube, and the lightweight outer tube can protect the carbon fiber inner tube to avoid carbon fiber.
