Abstract

The invention discloses an integrated ultrasonic welding machine for welding a battery cell pole. Comprising a workbench, two ultrasonic welding devices and a battery cell clamping device, the two ultrasonic welding devices and the battery cell clamping device are arranged on the workbench, the two ultrasonic welding devices are distributed at intervals, one ultrasonic welding device is used for welding a copper pole of a battery cell, and the other ultrasonic welding device is used for welding an aluminum pole of the battery cell. A linear rail in sliding fit with the battery cell clamping device is further arranged on the working table, so that the battery cell clamping device can slide to any ultrasonic welding device along the linear rail, and corresponding pole columns of the battery cell are welded through the two ultrasonic welding devices respectively; the two ends of the linear rail are provided with in-place baffles matched with the battery cell clamping device in an abutting mode respectively, so that after the battery cell clamping device slides to any in-place baffle, a pole on a battery cell fixed by the battery cell clamping device is located at the welding position of the corresponding ultrasonic welding device. The method is used for improving the welding quality and the welding efficiency of the battery cell pole.

Description

technical field [0001] The invention relates to the field of processing and production of lithium battery cells, in particular to an integrated ultrasonic welding machine used for welding electric core poles. Background technique [0002] The cells of lithium batteries usually include a plurality of copper foils and aluminum foils that are staggered with each other. Both the copper foils and the aluminum foils have strip-shaped extension strips to form tabs. The tabs of all copper foils are distributed on one side of the end of the cell and The negative pole is formed, and the tabs of all aluminum foils are distributed on the other side of the end of the cell to form a positive pole. After welding and fixing all the copper foil tabs and all aluminum foil tabs respectively, the cell is formed, and then the cell is formed. A battery module is formed by combining the cells in different series and parallel. [0003] There is a lack of welding tools for tabs in the prior art, re...
