The treatment device includes a plasma corona machine, a heat-setting drying tunnel and auxiliary equipment, and the plasma corona machine is connected to the heat-setting drying tunnel. The beneficial effects of the present invention are: it well solves the contradictory relationship between the electric field strength and the flat shape of the polyimide film in the field, overcomes the problem of the polyimide film being non-adhesive and having low peeling strength, and eliminates the problem of scrapping of the polyimide film due to deformation, which not only improves production efficiency and consolidates safety strength, but also effectively improves product utilization and greatly reduces production costs.

This polyimide film surface treatment device, through the transmission structure composed of a reciprocating screw, a moving block, a telescopic rod, a fixed block and a limit rod, can make the scraper bar reciprocate on the elastic scraper blade driven by a motor. This design can clean the impurities scraped off the elastic scraper blade in time to avoid impurity accumulation, ensure that the elastic scraper blade continues to maintain good cleaning performance, and maintain the cleaning effect on the film surface.

[0020] 5. In this polyimide film surface treatment device, the cleaning box, the second roller, the ultrasonic generator and the transducer in the cleaning mechanism cooperate with each other, and the high-frequency vibration of the ultrasonic wave can effectively remove the stubborn impurities on the surface of the polyimide film. After the film is initially cleaned and heated, it is further deeply cleaned, which significantly improves the overall effect of the film surface treatment. The stirring rod and the stirring blade on the cleaning box are connected to the chain wheel of the rotating rod below. When the rotating rod rotates, the stirring rod is driven to rotate, and then the stirring blade turns the cleaning liquid. This design enhances the relative movement between the cleaning liquid and the surface of the polyimide film, promotes the shedding and dispersion of impurities, and improves the cleaning efficiency. At the same time, the flowing cleaning liquid can promptly take away the impurities that have been stripped by the ultrasonic wave, prevent the impurities from adhering to the surface of the film again, and ensure the durability of the cleaning effect.
