About Laser Welding System Lub Tshuab Laser Welding

Lub Laser Welding System yog ib lub tshuab siv los txuas cov lithium batteries me me ua ke los ua power battery packs. Lub tshuab siv laser beam uas muaj high directivity thiab high power density ua nws lub hluav taws qhov chaw. Lub optical system focus lub beam rau ib qhov chaw me me kom yaus tau qhov txuas nyob rau lub sijhawm luv luv heev. Ib lub manipulator txav cov khoom mus los, yog li kev welding tiav tsis tas yuav siv neeg tes ua. Qhov dav, zog, peak power, thiab repetition frequency ntawm laser pulse tau raug tswj kom raws sijhawm. Lub tshuab ntev 8075 dav 1920 siab 2110 millimeters thiab pab txhim kho kev sib xws (consistency) thiab kev tsim khoom kom tau ntau zog (productivity).

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.
