Description

Panel Cleaning Device {Panel Cleaning Device}

The present invention relates to a panel cleaning apparatus suitable for cleaning a surface of a panel used for a liquid crystal panel, a television screen, or the like.

The panel used for a liquid crystal panel, a television screen, etc. is cut | disconnected to predetermined size, and is cleaned in order to remove the foreign material, such as cutting powder and resin, which adhered to the panel surface.

Such cleaning has conventionally been performed by moving a tape or a knife pressed on the panel surface while supplying the cleaning liquid to the panel surface (for example, JP-A 9-234432 and JP-A 11-28653). See publication).

However, in such a cleaning, foreign matter removed from the panel surface is pressed against the panel surface by a tape or a knife and rubs the panel surface, thereby causing a problem that the panel surface is damaged.

In addition, when the panel has a curved surface, the curved surface of the panel cannot be cleaned by conventional cleaning in which a tape or a knife is pressed against the panel surface.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a new panel cleaning apparatus suitable for cleaning a panel surface having a curved surface or a panel used for a liquid crystal panel or a television screen.
