Shanghai 2021 March 18 / US News / – The leader in the world’s high-end equipment, Germany Trump Group (TRUMPF) was announced in Munich Shanghai Guangbo in Munich, and the circulatory vibration mirror developed by China. Ultra-high speed scanning welding technology, this technology can greatly improve the welding speed, welding quality and automation level of the electrical cell top cover in the new energy vehicle power battery, improve the yield, reduce the floor area, simplify the laser welding system, greatly reduced the battery Manufacturer production costs. A conventional cell, after using the technique, the pre-welding and full welding time can be controlled within 1 second.
The cyclic core spinning mirror ultra-high-speed scanning welding technology is visually positioned, scanned welding, and the ring core adjustable welding technology (BRIGHTLINE WELD), Welded deep monitoring and welding surface quality monitoring total 5 partially, which can provide one-stop solution for this 5 part, and current solutions have been applied for national invention patent technology.
As the minimum constituent unit of the power battery, the module can be constituted, and the module can still form a battery pack. The battery cell is a power storage unit, which must have a higher energy density to store electrical energy as much as possible. The life of the battery is also the most critical factor, and the damage of any battery can result in damage to the entire battery pack.
The manufacturing method of the battery is not only related to the quality of the battery cell itself, but also determines the efficiency of manufacturing. Battery packs typically include numerous cells, therefore, choose efficient and stable manufacturing methods.
At the end of March 16, China’s laser “Golden Yao Award” selection ceremony, this patented welding technology also won the new technology gold award. Director of Wang Yilong, the Laser Processing Professional Committee of China Optics Society, said that “the power battery is currently the current market hotspot, and the fast patented welding technology solves the difficulty of the power battery welding. It is believed that the battery production will reach the new height.”
