AI Technical Summary
In the current new energy battery PACK manufacturing process, the welding process between the battery cell and the BMS circuit board is inefficient and the welding quality is unstable, making it difficult to ensure the consistency of the solder joint position, resulting in low product yield.
A laser welding auxiliary fixture is used. Through the combined design of a base, dual-sided cell positioning modules and a moving positioning module, high-precision alignment and welding of the cells and BMS circuit board are achieved. The flat abutment surface on the base and the coordinated limiting of the cell positioning module form a stable X-axis reference plane. Combined with the sliding adjustment of the moving positioning module, welding quality and efficiency are ensured.
It significantly improves the consistency and reliability of welding quality, shortens the welding cycle time, and increases process efficiency, making it suitable for mass battery module assembly scenarios.
