Apparatus for treating the surface of a curved material

Abstract

The present invention relates to an apparatus for processing a curved material for processing a uniform and clear surface for a surface of the curved material by using atmospheric pressure plasma. According to the present invention, the apparatus for processing the curved material includes: a high voltage electrode unit which is disposed on a convex-downward curved surface for multiple bar-type high voltage electrodes to have a curvature corresponding to a curvature of the curved material, which is a processing target; a housing which covers the upper side of the high voltage electrode unit in a separated state; a plasma discharging unit which covers the high voltage electrode unit on the lower side of the housing by forming the convex-downward curved surface and discharges plasma in a radial type by passing the high voltage electrode unit; a reaction gas supplying unit which is installed on the housing and supplies reaction gas in a space where the high voltage electrode unit is located; and a cooling unit which is formed in the center of the housing and cools the housing and the high voltage electrode unit by circulating cooling medium.

Description

technical field [0001] The present invention generally relates to a surface treatment apparatus, and more particularly, to a surface treatment apparatus for a curved object which uses atmospheric pressure plasma and which can uniformly and reliably treat the surface of the curved object. Background technique [0002] Typically, surface treatments for objects are often used before another substance, such as glass or a film, is attached to the object or before another treatment for the object is performed. In particular, a surface treatment method using atmospheric pressure plasma is widely used because the cost of surface treatment can be reduced, no environmental polluting material is generated during surface treatment, and the most reliable surface treatment effect can be obtained. [0003] Surface treatment using atmospheric pressure plasma is a technique that can satisfactorily treat the surface of a target object in such a way that an atmospheric pressure plasma generati...

Problems solved by technology

[0004] However, although a conventional surface treatment apparatus using atmospheric pressure plasma can uniformly treat a flat object by moving a target object horizontally or the surface treatment apparatus itself, there is a problem that it is difficult to uniformly treat the surface of a curved object.

[0005] In addition, if the curvature of the curved object is relatively large or the curved depression of the curved object is relatively deep, a large amount of plasma generated by the surface treatment apparatus using atmospheric pressure plasma does not uniformly reach the surface of the target object

In this case, it is almost impossible to process the surface of the target object
