About Laser Welding System Machine de soudage laser

Le système de soudage laser est une machine destinée à assembler par soudure des batteries lithium individuelles en blocs-batteries de puissance. Le système utilise comme source de chaleur un faisceau laser à haute directivité et à forte densité de puissance. Un système optique concentre le faisceau sur une zone réduite afin de faire fondre la jonction en un temps très court. Un manipulateur déplace les pièces, de sorte que le soudage s'effectue sans intervention manuelle. La largeur, l'énergie, la puissance de crête et la fréquence de répétition de l'impulsion laser sont contrôlées. Le système mesure 8075 sur 1920 sur 2110 millimètres et améliore la régularité ainsi que la productivité.

Unique Properties: The function of this system is to weld independent lithium batteries into power battery packs. The reasonable selection of welding methods and processes will directly affect the cost, quality, safety and consistency of the battery. The laser welding system uses the excellent directivity and high power density of the laser beam, assisted by the manipulator, to melt the welded object in a very short time and form firm solder joints and welds, improving consistency, reliability and productivity.
Dimensions & Packaging: 8075 mm x 1920 mm x 2110 mm
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.
