The battery tabs are usually divided into three materials. The positive electrode of the battery is made of aluminum material, and the negative electrode is made of nickel material or copper nickel-plated material. In the manufacturing process of power batteries, one of the links is to weld the battery tabs and poles together.

In the manufacture of the secondary battery, it needs to be welded with another aluminum safety valve. Welding not only needs to ensure the reliable connection between the tab and the pole, but also requires the welding seam to be smooth and beautiful. The following introduces the application of laser welding machine in the welding of lithium battery tabs.

Lithium battery welding is mainly in the welding of the tabs and caps and the sealing welding of the battery. In order to meet the needs of customers in the battery industry, we provide automated solutions. Through the production line and laser battery welding platform, the welding that originally required many process steps has become simpler and more efficient.

HGLASER has many years of R&D and production experience, always pays attention to the R&D of laser technology and the development needs of customers, and is committed to providing perfect material processing solutions for each customer.

Lithium battery cap electrode laser welding machine For the popular rectangular cross-section mobile phone battery, the sealing method is generally to have a rectangular cover plate on the top of the battery, with a positive lead-in end on the plate, and insert the cover plate into the shell and flush with the mouth , and then weld and seal the rectangular gap between the cover plate and the shell. The laser has high brightness, good directionality and good monochromaticity.

It is used to weld the seal of lithium battery case, which not only has minimal thermal deformation, direct and simple, neat and beautiful welding seam, but also is easy to cooperate with computer numerical control system or manipulator to realize automatic welding. ,high productivity.

The laser has a laser welding machine specially designed for lithium battery tab caps, as well as a special laser welding workbench, equipped with automatic fixtures, suitable for precision welding of various types of lithium batteries, and can be used for 0.2MM-1MM sealing welding, butt welding and sealing welding of stainless steel and aluminum of various shapes and sizes, and automatic laser welding of sealing of various types of power batteries.

 Compared with the traditional welding method, the laser welding machine replaces the two-dimensional worktable with a high-speed moving scanning lens, which greatly improves the welding speed and reduces the influence of the laser action on the material properties. Combined with professional software with powerful graphics processing function, program-controlled instantaneous multi-point welding is realized. The stable whole system provides the necessary conditions for industrial application. It enables customers to obtain higher efficiency and flexibility, lower costs, and better system integration in use, bringing products with stronger market competitiveness.
