New energy vehicles, solar energy, wind power grid, mobile communication base stations, electric logistics vehicles...... Batteries have played a crucial role in the development of the new energy industry.

Each square battery case is composed of a cover and a cover. The cover will seal a cover with a battery core to transfer the energy inside, and also ensure the safety of the battery core. It has high requirements on the sealing of the components, the relief pressure of the safety valve, electrical performance, size and appearance.

At present, the cover plate commonly used in the market has rivet column cover plate, minimalist column cover plate, pole injection type cover plate and so on. Although its structure forms are various, but most of them are composed of positive and negative parts and explosion-proof valve parts, therefore, its welding quality will directly affect the use and safety of the battery.

The power source of the new energy vehicle is lithium battery, power battery is a kind of power supply for a variety of tools, mainly for electric cars, trains, bicycles, golf carts and so on to provide electricity.

Power battery is a key component of new energy vehicle, and the structure design of its conductive joint is an important part. The connection mode between the cell and the module bus of the power battery is directly related to the production efficiency of the power battery and whether the production of the power battery can be automated.

In the welding of lithium battery module, laser welding, ultrasonic welding, resistance welding and other methods are used. Among them, laser welding combined with industrial robots has gradually become the main component of the automatic module production line. Adopt high efficiency welding technology, easy to realize automation.

Laser welding is a kind of high efficiency and high precision welding technology with high power laser as heat source. At present, there are many types of laser welding methods: positive and negative pole, explosion-proof valve, part of the cover plate and so on.

Xinde Laser automatic power battery PACK production line is suitable for explosion-proof valve welding, energy storage square aluminum shell core assembly.

The whole line is divided into PACK assembly line and assembly line. The key units are: mechanical hand material, sorting machine, extrusion and binding, CCD polarity detection, laser cleaning, side plate welding, busbar welding, total pressure insulation test, GN bad discharge mechanism, the main body of the total assembly line, etc., which can be customized according to user requirements.

The whole production line is simple to operate, easy to maintain, a high degree of automation, a comprehensive inspection of each process, to ensure the quality of products, MES traceability, accurate tracking of all welding and related process parameters.
