The invention discloses a device for processing an air plasma jet large area surface, comprising cylindrical gun rotary sleeves arranged circularly and a motor. Driven gears are sleeved on the gun rotary sleeves, driving gears engaged with the driven gears in transmission are respectively sleeved on a motor shaft of the motor, transmission belts are sleeved outside the driving gears and the driven gears which are matched with each other; the upper end surface of each gun rotary sleeve is provided with holes, a cylindrical cavity located in the gun rotary sleeve is rotationally sleeved and arranged in the holes; the upper port of the cavity is open, the lower port is in a gradually contractive round platform shape. An insulating sleeve is fixedly sleeved on the inner wall of the upper end of the cavity, an air inlet ring is fixedly sleeved on the inner wall of the insulating sleeve, centre of the air inlet ring is provided with a hole, an inner electrode capable of radiating the plasma jet is fixedly sleeved in the hole, the air inlet ring is provided with a plurality of through holes; the lower port of each gun rotary sleeve is provided with a detachable nozzle, and an included angle is formed between a central line and a central axis of the nozzle. The invention can provide a very clean surface and an adhesive capacity for material parts and has better economical efficiencywithout any negative effect to an environment.
Description
Technical field: [0001] The invention mainly relates to an air plasma jet large-area surface treatment device. Background technique: [0002] The traditional surface treatment is wet method, soaking and scrubbing with chemical solvents. The wet method is not universal, the processing quality is not high enough and the speed is slow, and it is difficult to realize automation. In particular, chemical solvents will cause secondary pollution, so people must look for new surface treatment technologies. [0003] Low-temperature plasma has extremely strong chemical activity, and can cause various chemical reactions or physical etching at room temperature, while the bulk properties of the host material are not affected. Through low-temperature plasma surface treatment, a variety of physical and chemical changes occur on the surface of the material, or it is etched and rough, or a dense cross-linked layer is formed, or oxygen-containing polar groups are introduced to clean, activate...
