Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a tension roller assembly for a copper strip electroplating production line. Background Technology

[0002] With the rapid development of the electronics industry, especially the high-speed development of new energy vehicles, various high-performance products are emerging in an endless stream, thus placing increasingly higher demands on the performance of basic materials. Copper alloy materials widely used in automotive connectors are required to maintain stable conductivity under any working environment. This necessitates materials with high temperature resistance, corrosion resistance, excellent weldability, stress release resistance to miniaturization, and lead-free compliance to meet environmental requirements. However, copper metal itself is prone to oxidation and discoloration, and this oxide film can affect conductivity. Therefore, applying a tin-plated layer to the surface of the material in contact with the external environment can meet this requirement.

[0003] By attaching a tin-plated layer to the surface of copper strip material in contact with the outside, tin is often used in the electronics industry as a substitute for silver plating due to its high chemical stability, low melting point, good solderability, conductivity, and resistance to discoloration. Through a special pretreatment process, a strong, bright, dense, uniform, and continuous tin plating layer is formed on the surface of the composite material, widely used for surface protection of electronic components, connectors, leads, and printed circuit boards. In addition to improving solderability, tin plating of copper strip also isolates it from the effects of sulfur in the insulating material. Tin-plated copper strip exhibits excellent oxidation resistance and solderability, improves the conductivity of connector contacts, ensures the operational stability and reliability of electrical components, and meets lead-free environmental protection requirements.

[0004] Current electroplating production lines require the use of tension rollers. In traditional tension roller assemblies, the copper strip comes into contact with the electroplating solution during copper strip tension control. Maintaining the surface cleanliness of the tension roller is crucial to prevent corrosion from the electroplating solution. Traditional setups struggle to keep the tension roller surface clean, significantly reducing its lifespan.

[0005] Therefore, it is of great significance to provide a tension roller assembly for copper strip electroplating production lines that can solve the problems existing in the prior art. Utility Model Content
