[0002] Copper alloy copper band is a kind of strip material alloyed by copper and other metal elements (such as aluminum, nickel, zinc, etc.), and is widely used in electronic, electrical, communication and automobile industries.Due to its superior conductivity, good plasticity and excellent corrosion resistance, copper alloy copper band plays an important role in manufacturing cables, connectors, radiators and other electronic components.However, during the production and use of copper alloy copper band, surface oxidation, contamination and other defects can affect its conductivity and appearance, and further affect the overall performance and service life of the product.Therefore, effective surface treatment of copper alloy copper band is particularly important.

[0004] However, the existing technology has certain limitations during use, although the brush cylinder can effectively remove the oxide skin on the upper surface of the copper band, but since it is only arranged on the upper surface of the copper band, the lower surface and both sides cannot be effectively treated.Especially, the two sides of the copper band are prone to produce burrs after the upper surface is treated, and if not treated, these burrs can potentially harm the user.Therefore, in view of this defect, we propose a copper alloy copper band surface treatment device to realize comprehensive and efficient surface treatment, and ensure the safety and reliability of copper alloy copper band during use.
