About Laser Welding System High Precision
Laser Welding System is a machine for welding individual lithium batteries into power battery packs. The system uses a laser beam with high directivity and high power density as its heat source. An optical system focuses the beam on a small area to melt the joint in a very short time. A manipulator moves the parts, so welding is completed without manual work. The width, energy, peak power and repetition frequency of the laser pulse are controlled. The system measures 8075 by 1920 by 2110 millimetres and improves consistency and productivity.

- Tags
- laser, welding, system, power, battery
- Production Technology
- Laser welding is an efficient and precise welding method that uses a high-energy density laser beam as a heat source. That is, the surface of the workpiece is heated by laser radiation, and the surface heat is diffused to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, etc. Parameters to melt the workpiece.
- Design Challenge
- The structural design of large-scale equipment is more difficult, and the interaction design between humans and machines
- Research
- The welding of automobile power battery requires a high degree of consistency. This design is for the batch welding of batteries and improve the reliability and efficiency of production. The internal manipulator can complete this work fully and efficiently without unmanned operation.
- Inspiration
- Laser welding has high efficiency and is easy to realize automated production. After continuously improving the welding process and limiting the thermal influence in the forming process, more and more applications are used in actual production. Laser welding with industrial robots is gradually becoming the main force of the automated power battery module production line.
- Project Duration
- March, 2019. Guangzhou, China
- Operation Flow
- The laser welding system uses the excellent directivity and high power density of the laser beam to work. With the assistance of the manipulator, the optical system focuses the laser beam in a small area to form an energy in the welded area in a very short time. Highly concentrated heat source area, so that the welded object melts and forms a firm solder joint and weld seam.
