Apparatus for compressing joint of electrode tab and electrode lead

An apparatus for compressing a joint formed between an electrode tab extending from an electrode assembly and an electrode lead, the apparatus comprising:

• an upper pressing unit;
• a lower pressing unit;
• a driving unit configured to move the upper pressing unit and the lower pressing unit up and down;
• and
• a suction unit,
• wherein the upper pressing unit comprises an upper compressing member protruding toward the lower pressing unit and an upper support member in which the upper compressing member is fixed to a lower portion of the upper support member, and the lower pressing unit comprises a lower compressing member protruding toward the upper pressing unit and a lower support member in which the lower compressing member is fixed to an upper portion of the lower support member,
• wherein the upper compressing member and the lower compressing member are located in opposite directions on the same line, and are moved to a compressed position by driving the upper support member and the lower support member toward each other, and are separated by driving the upper support member and the lower support member in opposite directions from each other, and
• the upper support member comprises an upper air injection nozzle configured to inject air toward the joint,
• wherein the upper air injection nozzle is configured to operate when the joint is positioned in a state where the upper compressing member is raised, not to operate from a time when the upper compressing member is lowered to a time when the upper compressing member is raised through a compression process, and to operate again when the joint is discharged after the compression process is completed,
• wherein the lower support member further includes a lower air injection nozzle configured to inject air toward the joint, and
• wherein the lower air injection nozzle is configured to operate when the joint is positioned in a state where the lower compressing member is lowered, not to operate from a time when the lower compressing member is raised to a time when the lower compressing member is lowered through a compression process, and to operate again when the joint is discharged after a compression process is completed.
