Laser Welding Machine for Prismatic Cell Top Lid and Filling Port Sealing

Laser Welding Machine for Prismatic Cell Top Lid and Filling Port Sealing

SPECIFICATIONS

This TOB-LW-SF3000 prismatic cell top lid and filling port laser welding machine is a core component in prismatic lithium-ion cell assembly, responsible for the final, permanent hermetic sealing of the cell enclosure (lid-to-can) and the electrolyte filling port. It ensures the structural integrity, safety, performance, and lifespan of the finished battery cell.

Top Lid Sealing: 

Precisely welding the cell cover (lid) onto the prismatic aluminum alloy cell can body. This creates a hermetic, gas-tight, and electrically insulated seal essential for cell integrity, safety, and long-term performance. It prevents electrolyte leakage and ingress of moisture or contaminants.

Manual core loading - fixture clamping - laser pre-welding - full welding - manual core unloading

Filling Port Sealing: 

Welding the electrolyte filling port plugb after electrolyte filling is complete. This permanently seals the fill hole, maintaining the internal environment and pressure of the cell.

Manual core loading - fixture clamping - manual installation of sealing nails - laser welding - manual inspection and discharging.

Adaptation specifications: Prismatic battery
