Abstract

The invention discloses a pole lug welding device. The pole lug welding device comprises a fixture base, a battery core pressing plate, a pole lug pressing plate and a welding device. According to the pole lug welding device, a first platform is matched with the battery core pressing plate for achieving pressing of a battery core, and therefore the position of the battery core is prevented from changing in the welding process; a second platform is matched with the pole lug pressing plate for achieving pressing of pole lugs, and therefore the position of each pole lug is prevented from changing in the welding process; and welding of the pole lugs is achieved through the welding device. According to the pole lug welding device, stable positioning of the battery core and the pole lugs is achieved, the position of the battery core and the position of each pole lug cannot be changed in the welding process, positioning accuracy of the pole lugs in the welding process is guaranteed, and therefore the production quality of the battery core is improved to some extent.

Description

technical field [0001] The invention relates to the technical field of electric core processing, in particular to a tab welding device. Background technique [0002] Ultrasonic welding is mostly used for the welding of tabs, and the quality of tab welding affects the quality of batteries. [0003] In the prior art, due to the low positioning accuracy of the tabs during welding, the welding position of the tabs is inaccurate, which affects the production quality of the battery cells. [0004] Therefore, how to achieve accurate positioning of the tabs to improve the production quality of the battery cells has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0005] In view of this, the present invention provides a tab welding device to realize accurate positioning of tabs and improve the production quality of electric cores. [0006] To achieve the above object, the present invention provides the following technical s...
