Description

Technical Field

[0001] This utility model relates to the field of copper foil processing technology, and in particular to an electrolytic copper foil tensioning device. Background Technology

[0002] Electrolytic copper foil is a type of copper foil produced through electrolysis, commonly used in circuit board manufacturing. It is produced by placing copper anodes and cathodes in an electrolyte in an electrolytic cell and applying an electric current. During this process, copper on the anode dissolves in the electrolyte and precipitates on the cathode to form copper foil. Copper foil produced using this method has high purity, uniform thickness, and good conductivity, making it ideal for manufacturing high-performance circuit boards. Electrolytic copper foil tensioning devices are used during the processing to maintain the correct position and tension of the copper foil within the electrolytic cell during transport, ensuring production stability and product quality.

[0003] Currently, most electrolytic copper foil tensioning devices on the market use conveyor rollers to transport and rewind the copper foil. During the transport and rewinding process, the electrolytic copper foil may shake due to factors such as traction speed and tension, resulting in uneven corrosion of the electrolytic copper foil during electrolysis. This affects the processing quality of the electrolytic copper foil and fails to meet the needs of users. Utility Model Content
