Fiber laser marking machine important equipment for new energy industry processing

With the advent of the new energy era, laser welding equipment has become an important processing tool. For example, the manufacture of new energy vehicles is always inseparable from the existence of laser welding machines. Welding technology plays a good role in promoting, such as battery tabs, shell sealing welding, battery cells, caps, battery pack line automatic welding and other accessories require laser equipment to 'escort forward'.

The laser welding machine for battery tabs has only been developed in recent years. I believe that many small and medium-sized battery accessories companies are still using traditional resistance welding machines, but as the saying goes, 'no There is no harm in comparison.' The tab laser welding machine will become an important equipment for the future battery tab welding industry.

Laser welding machine for battery tabs

The welding of battery tabs is divided into positive and negative, and its materials include aluminum, nickel, copper and other materials, among which the welding of aluminum to nickel tabs is more difficult Generally speaking, the quality requirements of laser welding machines are relatively high, but from the perspective of traditional resistance welding processing, the welding quality has generally not met the requirements of today's quality and safety, mainly because the resistance welding is not firm, or it is easy to break down, Poor welding stability and low production efficiency.

Later, some users began to use ultrasonic welding machines to weld the tabs, but it was difficult to realize automation. The key point was that the welding speed was slow, which could not meet mass production at all, and the efficiency was low. The cost cannot be reduced, so in order to meet the needs of this type of tab welding process, a welding machine professionally used for welding battery tabs, that is, a tab laser welding machine, is born. Its obvious advantage is that the welding speed of the tabs is fast. The processing quality is good, and automation can be realized. It has already belonged to the quality requirements of high-end users in the welding of tabs!
