A battery cell cap tab welding equipment and its working method

Abstract

The invention discloses welding equipment for a cap and a pole tab of a battery cell. The welding equipment comprises a workbench, wherein a cap taking and discharging mechanism, a cap and pole piece correcting mechanism, a cap picking and shaping mechanism and an overwelding station are sequentially mounted on the lower side of the surface of the workbench from left to right; a pole tab folding and battery cell cap pressing mechanism and a battery blanking mechanism are sequentially mounted on the upper side of the surface of the workbench from right to left; a guide rail is slidingly connected with a battery cell cap carrying return mechanism; and a battery cell removal mechanism and a pole tab correcting mechanism are arranged on one side of the right end of a battery cell charging belt. The welding equipment replaces the traditional manual production with automatic battery cap welding and sealing production tools, so that the production efficiency is improved, and the production cost is greatly lowered. The cap picking and shaping mechanism, the battery cell removal mechanism and a pole tab cleaning mechanism monitor and process the quality of a semi-finished product for producing a battery, so that a defective rate of a finished product is reduced, and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of battery cell cap tab tab welding, in particular to a battery cell cap tab tab welding device and a working method thereof. Background technique [0002] During the battery production process, the battery cells need to be put into the battery case, and then the pole piece on the cap is welded to the tab on the battery cell. After welding, the cap is fastened on the battery case to make the battery sealed. In order to facilitate the welding of the pole piece, it is necessary to lift the pole piece from the cap, and rotate the pole lug and the cap to the corresponding positions respectively, so that the pole lug and the pole piece are aligned for welding. The welding strength of the pole piece is tested to reduce the defective rate. However, if the above-mentioned series of processes are completed manually, the efficiency will be low, and it will consume a lot of labor costs and time, resulting in high prod...
