About Laser Welding System Laserlasmachine

Het lasersysteem is een machine voor het lassen van individuele lithiumbatterijen tot batterijpakketten. Het systeem gebruikt een laserstraal met hoge richtingsgevoeligheid en hoge vermogensdichtheid als warmtebron. Een optisch systeem bundelt de straal op een klein oppervlak om de verbinding in zeer korte tijd te smelten. Een manipulator verplaatst de onderdelen, waardoor het lassen zonder handmatige arbeid wordt voltooid. De breedte, energie, piekvermogen en herhalingsfrequentie van de laserpuls worden geregeld. Het systeem meet 8075 bij 1920 bij 2110 millimeter en verbetert de consistentie en productiviteit.

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

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.
