Battery Pole Ear Laser Welding

Application Description

Mobile Phone Battery Specification                                           
Length: 40-120mm
Width: 30-80mm
Height: 2-5mm

Standard
The welding surface is smooth, and no obvious color change, no welding penetration.

Advantage
Superior rate ≥99 %
Productivity/Efficiency≥900 UPH
Welding speed 110～130mm/s

Technology

Difficulties
1. The pole ear is thin so that it is easy to deform and lead to poor welding.
2. The welding energy is unstable, and it is easy to produce welding penetration.

Solution
Tips 1: Integrate the laser welding machine with the position of pole ear shaping, cutting, dimension detection, and protection board welding avoid the risk of pole ear deformation.
Tips 2: Use energy negative feedback to ensure the stability of the energy.
Tips 3: Use the scanner to ensure the welding efficiency.
