Abstract

The invention discloses a polyimide film winding device, and relates to the technical field of polyimide film winding. The device comprises an unwinding assembly and a winding assembly, the winding assembly is located on the left side of the unwinding assembly, and an ultraviolet radiation assembly, a tensioning controller, a deionization assembly, a moving assembly and a cutting assembly are sequentially arranged between the unwinding assembly and the winding assembly from right to left. Through combination of ultraviolet irradiation and ion wind technologies, ultraviolet irradiation can effectively destroy charge accumulation caused by surface static electricity. Polyimide surface molecules are subjected to a photochemical reaction due to irradiation of ultraviolet light, the surface conductivity of the material is enhanced, release of electrostatic charges is promoted, the surface electron mobility of the polyimide film is improved, positive and negative ions are generated through an ionic wind technology by means of a high-voltage electric field, ionic wind is formed to neutralize static electricity, the static electricity can be eliminated more quickly, and the elimination effect is enhanced. And meanwhile, physical damage to the thin film structure is avoided.
