What are the main applications of laser welding machine equipment in the lithium battery industry?

The key information technology for the future economic development of electric new energy vehicle enterprises is the safety, cost and energy storage capacity of power lithium-ion batteries. Power lithium battery production production process to carry out complex, high safety management requirements; its production teaching process of one of the key construction process design technology is China's laser welding engineering technology;battery pilot machine power lithium battery laser welding processing technology mainly includes a battery soft connection welding, top cover welding, sealing nail welding, module and PACK welding. Power lithium battery laser welding parts more, reliability and safety and stability requirements, the laser welding equipment put forward with higher requirements.

Lithium battery welding applications

Lithium battery welding methods and their advantages and disadvantages.

① wave welding: essentially a blend of ultrasonic welding and laser welding;

Ultrasonic welding: the advantage of this program is easy to weld, but need to take up more space in the room, and the efficiency of the volume module of the test group is lower;

③Laser welding: this solution is currently the most widely used, but the design is slightly different;

④ not the same metal materials for laser welding: this type of welding technology method group block high efficiency is also very high,battery laser welding machine the production of products manufacturing development can be faster.

Laser welding equipment in the lithium battery industry is the main application?

Laser welding is the use of laser beams to melt and weld objects in the process. In the manufacturing process of lithium batteries and battery packs for new energy vehicles, there are more than 20 processes that need to be connected or sealed by welding.

Specifically, laser welding applications include.

(1) Pole manufacturing section - front section: the cutting link between pole and diaphragm adopts laser cutting technology.

(2)Core assembly section-middle section:Laser for welding technology process can be applied to different shells, battery packing machine top cover, sealing nails, pole lugs and other welding work links.

(3) Post-processing section - Post-processing: Battery pack module connector welding.

Lithium battery laser welding machine

As a high-precision production process, laser welding effectively improves the safety, reliability and service life of power battery. The energy density, safety performance and production automation requirements of power batteries have been gradually improved, which put forward higher requirements for the accuracy, safety and consistency of production equipment.
