Embodiment Construction

[0055] In the ensuing description of the different exemplary embodiments according to the invention, identical components are provided with the same reference numerals, even though these may differ in size or shape in different exemplary embodiments.

[0056] Before describing the first embodiment according to the present invention, first by means of figure 2 The structure of the plasma nozzle on which the present invention is based will be described.

[0057] exist figure 2 The device 2 shown and known from EP 1067829 B1 for generating a plasma beam has a tubular housing 10 which is enlarged in diameter in its upper region in the illustration and mounted rotatably on a bearing 12 On the fixed carrier tube 14. In the interior of the housing 10 is formed a nozzle channel 16 which extends from the open end of the carrier tube 14 to a nozzle opening 18 .

[0058] An electrically insulating ceramic tube 20 is placed in the carrier tube 14 . A working gas, such as air, is add...

Abstract

The invention relates to a device for generating an atmospheric plasma beam for treating the surface of a workpiece, comprising a tubular housing (10) which has an axis (A), an inner electrode (24) arranged within the housing (10), and a nozzle assembly (30) which has a nozzle opening (18) for discharging a plasma beam to be generated in the housing (10). The direction of the nozzle opening (18) runs at an angle relative to the axis (A), and the nozzle assembly (30) can be rotated about the axis (A). The aim of the invention is to develop the aforementioned device, system, and method for treating the surface of a workpiece such that the aforementioned disadvantages are at least partly eliminated and a uniform treatment of the surface is achieved. This is achieved in that a shield (40) surrounds the nozzle assembly (30), and the shield (40) is designed to change the intensity of the interaction of the plasma beam to be generated with the surface of the workpiece depending on the rotational angle of the nozzle assembly (30) relative to the axis (A). The invention also relates to a method for treating the surface of a workpiece.

Description

technical field [0001] The invention relates to a device for generating an atmospheric pressure plasma beam for treating the surface of a workpiece with a pivoting plasma beam which produces a wide treatment trajectory as it moves over the surface. Furthermore, the invention relates to a device having at least one plasma device, which rotates about an axis and thereby generates at least one plasma beam which traverses the surface in a circular motion. When the at least one plasma beam moves across the surface, broad treatment tracks also occur. Furthermore, the invention relates to a method for treating a workpiece surface with such a device or such a structure. [0002] Within the framework of this description, treatment of a surface with a plasma beam means a surface pretreatment by which surface stresses are changed and better wettability of the surface by liquids is achieved. In addition, surface treatment can also mean surface coating by adding at least one precursor to...
