Lithium Battery Pack Laser Welding Batteries Spot Laser Welding Machine

In recent years, the wave of new energy vehicles has become popular all over the world. Among them, the power battery, as the core component of a new energy vehicle, directly determines the performance of the vehicle. The accuracy and automation level of the production equipment will directly affect the quality, efficiency and consistency of the battery. As an advanced processing technology, laser welding technology is a good choice for the production of high-performance power batteries. Due to the large number of welding parts, the difficulty of welding, and the high precision requirements of power batteries, traditional welding methods are difficult to meet the requirements. However, laser welding technology has low welding material loss, small deformation of the welded workpiece, stable equipment performance and easy operation, welding quality and automation. High, used in the field of power battery welding can greatly improve the safety and reliability of the battery, and extend the service life. As a fusion manufacturing process that integrates raw materials such as positive and negative electrode materials, separators, and electrolytes, it is a key process in the entire power battery production process.

working principle

Laser welding uses high-energy laser pulses to locally heat the material in a small area, and then diffuses into the material through heat conduction to melt the material to form a specific molten pool. It is a new type of welding method, mainly aimed at welding thin-walled materials and precision parts, and can realize multiple welding methods such as spot welding, butt welding, stitch welding, and sealing welding.

Features

The laser welding for power battery has the advantages of high energy density, small welding deformation and small heat affected zone, which can effectively improve the precision of the parts. The welding seam is smooth without impurities, uniform and compact, and no additional grinding work is required.Energy concentration and control, equipment welding speed is fast, easy to achieve automatic production, high yield, better battery welding safety, no side effects on the human body, suitable for use in dust-free workshop.Because the structure of the power battery usually contains a variety of materials, the power battery laser welding machine can weld between the opposite metal.
