For the workpiece with high precision requirements, the laser welding equipment with higher precision and more powerful is usually used. And for high-precision welding of electronic equipment, Xin De laser research and development of a gantry large-format continuous fiber laser welding machine.

Mr. Zhang Yang, general manager of Xinde Laser, said that the growth of demand for new energy vehicles has prompted the rapid upgrading of products in the field of lithium electric equipment. In terms of capacity, the newly built capacity of Xindel Laser has increased by 30% compared with last year. In the future, we plan to build a new production base which can increase the existing capacity of the company by 80%.


He also said that Xinde Laser is focused on the production of lithium battery laser welding equipment enterprises, the company to research and production of equipment products, compared with other products in the industry has greater advantages, can provide customers with high-quality lithium laser welding equipment and automation solutions.

Today's new energy vehicles can accelerate 100 kilometers in just a few seconds, allowing more people to experience the pleasure of "super running". The power to drive new energy vehicles is generated by hundreds of lithium-ion Cell cells. In the manufacturing process of lithium batteries or battery packs, more than 20 processes need to be welded to achieve conductive connections or seals. The quality of welding plays a vital role in the safety performance of the vehicle.


Laser welding is an important non-contact welding means, which realizes the interatomic bonding of two separated products by focusing the high energy laser beam on the surface or inside of the product to be processed. Compared with traditional argon arc welding, resistance welding, ultrasonic welding laser welding has significant advantages: first, the heat affected zone is small; Non-contact processing; Third, high processing efficiency.


In the field of new energy lithium electricity, laser welding technology has been large-scale used in pole ear, core shell, sealing nail, soft connection, explosion-proof valve, battery module welding.


The square lithium battery includes aluminum shell square battery and steel shell square battery. The internal process is winding or laminated. The protection of the battery cell is better than that of the soft pack battery, and the safety of the battery cell is improved compared with the cylindrical battery.


The share of aluminum shell of lithium battery is higher than that of steel shell, which is decided by the advantages of high hardness, light weight, safety and high performance of aluminum shell. The square lithium battery can be customized according to the product size, so there are many models and specifications on the market, which makes the process of the square battery difficult to be unified. Square battery standardization is a trend, which is of great significance for the production and maintenance of the component.


The welding of square battery shell cover plate is divided into top welding and side welding. The top of the plate has a rectangular cover plate, the plate with a positive terminal, the cover plate into the shell and the upper mouth flush, and then the laser cover and the rectangular gap between the shell, with repeated continuous laser welding seal, this welding process is called top welding, top welding laser beam can not move, the battery is fixed on the workbench, laser beam alignment weld, Start the work table so that the battery along the work table X and Y coordinates out of the same rectangle shape as the weld. When the cover plate of square battery adopts the top welding sealing structure process, there is no positioning step for the cover plate, and the tolerance of length and size is strict, and the welding and assembly accuracy is high.
