Welding Apparatus For Electrode Tab Of Cylindrical Type Secondary Battery And Method For Manufacturing Cylindrical Type Secondary Battery

摘要

The present invention relates to an electrode tap welding apparatus for a cylindrical rechargeable battery and a method of manufacturing a cylindrical rechargeable battery. The electrode assembly includes an electrode assembly formed by winding a plurality of electrodes and a separator, and a cylindrical body An apparatus for welding an electrode tab of a cylindrical rechargeable battery including a can, comprising: a magnetic force applying unit for generating a magnetic force outside the cylindrical can so that an electrode tab connected to the electrode moves to a bottom surface side of the cylindrical can; And a laser part for irradiating a laser so that the electrode tab is welded to the bottom surface of the cylindrical can. According to the present invention, there is provided an electrode tap welding apparatus for a cylindrical rechargeable battery which can weld an electrode tab without using a welding rod, and a method for manufacturing a cylindrical rechargeable battery.
