AI Technical Summary
Existing roll-to-roll magnetron sputtering equipment, when producing aluminum-based copper foil, suffers from the risk of scratches and hidden wrinkles due to its complex multi-roller path design. Furthermore, the equipment is inconvenient to maintain, which affects production efficiency.
Employing a minimalist seven-contact roller path design, combined with an adjustable flattening roller structure and a feedforward-state-maintaining tension control strategy, uniform coating of aluminum foil and reduced friction are ensured by adjusting the curvature of the flattening roller and monitoring the tension in real time.
This technology achieves highly uniform coating on aluminum-based copper foil, reducing the risk of scratches and wrinkles on the aluminum foil and improving production efficiency and equipment maintenance convenience.
