Abstract

The utility model provides an electrostatic adsorption winding device, which belongs to the technical field of lithium battery diaphragm production and comprises a bearing mechanism, a bearing frame and a diaphragm breaking component arranged at the top of the bearing frame. The high-voltage electrostatic generator enables the electrostatic generating rod to generate static electricity on the surface of a film in the winding, roll changing and breaking process, the film has adsorption force, and therefore the film can be attached to the axis of a new roll, consumable items such as double faced adhesive tape do not need to be used, and production cost is effectively reduced. The blowing assembly can blow air to the film, the success rate that the film is attached to the roll core is further increased, attachment of dust and impurities to the surface of the film is reduced, the static electricity eliminator can instantly neutralize static electricity on the surface of the film, the phenomenon that the static electricity attracts the dust and other impurities is avoided, and the product quality is further improved, so that the device can efficiently improve the product quality. The probability of being influenced by external factors is reduced, and the bottom wrinkle flatness of the thin film is effectively improved.
