MSK-LW-S2000 2KW Fiber Laser Welding System for Prismatic Cell Tab Welding and Top Lid Sealing, Compatible with Cylindrical Cells
The MSK-LW-S2000 is engineered to address the critical welding and sealing steps in prismatic battery cell assembly. It specializes in two main operations: welding the current collector tabs and sealing the top lid or cap of prismatic cells. This system also accommodates cylindrical cells, providing versatility for battery manufacturing and research environments.
Utilizing a 2,000-watt fiber laser operating at a wavelength of approximately 1075 nm, the system delivers stable and high-quality laser output optimized for highly reflective materials such as aluminum and copper. The laser power is adjustable from 10% to 100%, allowing precise control over the welding process. The system incorporates a CCD camera for positioning with an accuracy of 0.02 mm, enabling rapid and precise alignment of components. The XY stage supports effective traverse distances of 880 mm by 230 mm, with a Z-axis range of 2400 mm, facilitating accommodation of various cell sizes.
