Abstract

The invention discloses a laser welding device for a tab of a battery module. The device comprises a rack platform, a bending mechanism, a rolling mechanism, a laser welding mechanism and an index plate mechanism, wherein the rack platform is provided with a bending area, a rolling area and a welding area; the bending mechanism is mounted in the bending area and is used for bending the tab of the battery module; the rolling mechanism is mounted in the rolling area and is used for rolling the tab of the battery module; the laser welding mechanism is installed in the welding area and used for conducting laser welding on the tab of the battery module; and the index plate mechanism comprises an index plate and a first driving device, and the first driving device is used for driving the index plate to rotate so as to drive the battery module placed on the index plate to rotate, so that the battery module can pass through the bending area, the rolling area and the welding area. The welding automation of the battery tab can be realized, the quality of tab welding is improved, further, the qualified rate of tab welding is improved, meanwhile, the operation is easy, and application and convenience are achieved.

Description

technical field [0001] The invention relates to the field of tab welding of battery modules, in particular to laser welding equipment for tabs of battery modules. Background technique [0002] With the increasingly severe energy and environmental issues, driven by industrial policies and markets such as energy conservation and emission reduction, green credit, and green securities, lithium batteries are a power source for power tools, electric vehicles, electric bicycles and other A variety of electronic devices provide power for batteries, which have the advantages of long life, practical safety, large capacity, small size, and light weight, and are widely used in many fields. [0003] Lithium batteries are generally provided with multiple sets of tabs, and the multiple sets of tabs are connected in series and parallel by connecting the drains, wherein the tabs can be connected to other power systems (such as the power system of an electric vehicle). At present, the tabs a...
