APPARATUS AND METHOD FOR MANUFACTURING SECONDARY BATTERY

The present disclosure provides an apparatus and method for manufacturing a secondary battery, in which it is possible to minimize damage to a separator and increase welding strength by maintaining a safety distance between a stack of an electrode assembly and a current collector and also securing good adhesion between an electrode tab and a current collector when the current collector is welded to the electrode assembly. The apparatus for manufacturing a secondary battery includes a side pusher disposed to correspond to an electrode assembly having an electrode tab and formed to move and press a sub-tab, which will be welded to the electrode tab, toward the electrode tab through linear movement, a first driving module that allows the side pusher to linearly reciprocate, a support jig installed so that a position thereof is adjustable between the electrode assembly and the side pusher, and a second driving module configured to stop movement of the support jig while the sub-tab is in contact with the electrode tab and allow the support jig to block a pressing force of the side pusher from being further transmitted to the electrode tab.
