Laser welding system for power batteries

Abstract

The invention relates to the field of power battery welding, in particular to a laser welding system for power batteries. The laser welding system comprises a material shifting flow channel, a material shifting mechanism, a welding mechanism and a detection mechanism, wherein the material shifting flow channel is arranged between a feeding logistics line and a discharging logistics line and is provided with a welding station and a detection station, the material shifting mechanism is arranged on the material shifting flow channel, the welding mechanism is arranged on the welding station, and the detection mechanism is arranged on the detection station. According to the laser welding system which is arranged in an integrated mode, the power batteries can be efficiently welded, in addition,the structure layout mode can adapt to square power batteries with different specifications and size, and therefore the labor production and remodel cost of customers can be greatly lowered; and meanwhile, the positioning precision of the power batteries can be improved, so that the welding precision can be guaranteed, and therefore the production speed can be increased, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the field of power battery welding, in particular to a laser welding system for power batteries. Background technique [0002] The development of new energy vehicles continues to grow. At the same time as the advantages and share of the global new energy vehicle market are expanding, the country has also introduced relevant measures for the development and innovation of new energy, especially new energy vehicles, which has triggered the production demand for new energy power batteries. The size and specification of new energy power batteries are also increasing; the existing laser welding system cannot meet the requirements of the above-mentioned huge increase in the production demand of power batteries.

[0002] The development of new energy vehicles continues to grow. At the same time as the advantages and share of the global new energy vehicle market are expanding, the country has also introduced relevant measures for the development and innovation of new energy, especially new energy vehicles, which has triggered the production demand for new energy power batteries. The size and specifications of new energy power batteries are also getting larger and larger; the existing laser welding system cannot meet the requirements of the above-mentioned huge increase in the production demand of power batteries

[0003] At the same time, the battery positioning jig is driven by the rotary table and linear type. At the same time, the size and weight of the power battery will also affect the size and weight of the battery positioning jig. The heavier the battery positioning jig is, the bigger the battery positioning jig is. The movement (rotation) accuracy and speed of the positioning fixture movement method will be reduced to varying degrees
