Abstract

The invention discloses a laser welding fixture for power batteries. The fixture comprises a bottom plate (1), wherein two limiting plates (15) used for welding are arranged at the rear end of the bottom plate (1) at an interval; a sliding table cylinder (9) is respectively arranged right ahead each limiting plate (15) used for welding; a battery fixture positioning plate (7) and a mobile limiting plate (14) are respectively arranged on the upper surface of each sliding table cylinder (9) in tandem; at least one battery fixture guide shaft (12) is respectively fixed to the left end and the right end of each battery fixture positioning plate (7); each mobile limiting plate (14) is connected with each battery fixture positioning plate (7) through the battery fixture guide shaft (12); and a groove is reserved in the middle of each battery fixture positioning plate (7). The laser welding fixture for the power batteries disclosed by the invention can maintain the stability of battery clamping, ensures the welding reliability of the power batteries in various welding fields, and improves the quality passing rate of the power batteries.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a power battery laser welding jig. Background technique [0002] At present, lithium-ion batteries have the advantages of high specific energy, many cycle times, and long storage time. They are not only widely used in portable electronic devices such as mobile phones, digital cameras, and laptop computers, but also widely used in electric vehicles and electric bicycles. And large and medium-sized electric equipment such as electric tools. [0003] With the maturity and improvement of electric vehicle technology, the dream of electric vehicles and hybrid vehicles entering daily life has become possible, and the widespread popularity of electric vehicles has given birth to huge business opportunities. Power batteries are mainly used in power vehicles. Due to the complex use environment, the safety performance requirements for power batteries are more stringent. The performance...
