Description

Technical Field

[0001] This utility model relates to the field of conductive film technology, specifically a winding device for conductive film production. Background Technology

[0002] Conductive films are thin-film materials with conductive properties. The substrate is often made of polyester (PET) film, which possesses insulation, heat resistance, and high elasticity. Film layers with a thickness of less than 0.25 mm are mainly used in membrane keyboard touch panels, while substrate layers with a thickness greater than 0.25 mm serve as structural backing. This material is widely used in antistatic films, membrane keyboard circuits, touchscreen sensors, and solar cell electrodes. Among these, ITO (indium tin oxide) conductive films stand out due to their 85%-95% light transmittance and 10... -4 ~10 -3 With a resistivity of Ω·cm, carbon nanotubes have become a core electrode material for liquid crystal displays, OLEDs, and perovskite batteries. Preparation techniques encompass magnetron sputtering, chemical vapor deposition (CVD), and vacuum evaporation, with CVD achieving solid-state deposition through the reaction of gaseous substances. Emerging technologies include the spraying process for flexible carbon nanotube conductive films, applicable to touch-sensitive layers in touchscreen phones, whose flexibility supports bendable flexible touchscreens. In terms of material innovation, copper-based p-type transparent conductive films (CuI) reduce costs by 70% compared to traditional materials. Current applications have expanded to automotive dimming glass, AR / VR optics, and electromagnetic shielding. After production, conductive films require winding for transportation and sales. Existing winding devices for conductive film production are not convenient for changing rolls, thus affecting winding efficiency. Utility Model Content

The unwound take-up drum 6 is placed on the surface of the rotating shaft 5 and pushed to the right. The take-up drum 6 drives the blocking block 13 to be inserted into the inside of the limiting groove 12.
