Pressurization jig for pressurizing busbar and battery module manufacturing system comprising same

A pressing jig for welding, which is installed at one side of a battery module to press a bus bar of the battery module at both sides thereof so that an electrode lead located in a lead slit formed at the bus bar is able to be welded to the bus bar in a closely adhered state, the pressing jig comprising:

• a first frame having a first distance adjusting unit and a first pressing unit;
• a second frame having a second distance adjusting unit facing the first distance adjusting unit and a second pressing unit facing the first pressing unit;
• a hinge configured to couple the first frame and the second frame;
• a first fixing portion extending from one end of the first distance adjusting unit in a direction away from the hinge, and a second fixing portion extending from one end of the second distance adjusting unit in the direction away from the hinge,
• a restoring member connected between the first fixing portion of the first distance adjusting unit and the second fixing portion of the second distance adjusting unit;
• and
• a distance adjusting knob adjusting a distance between the first distance adjusting unit and the second distance adjusting unit,
• wherein the first frame and the second frame are coupled by the hinge so that a distance between first pressing unit and the second pressing unit is increased when a distance between the first distance adjusting unit and the second distance adjusting unit is decreased, and the distance between the first pressing unit and the second pressing unit is decreased when the distance between the first distance adjusting unit and the second distance adjusting unit is increased, and
• wherein the hinge, the restoring member and the distance adjusting knob are separated from each other so that the distance adjusting knob is located between the hinge and the restoring member.
