Suction apparatus

A suction apparatus for suctioning an upper surface of each of a plurality of battery cells loaded in a loading box and sequentially taking out and transporting the battery cells, the suction apparatus comprising:

• a main body including a frame which is configured to move linearly in a Z-axis direction and a main cam which is configured to linearly reciprocate in a Y-axis direction inside the frame;
• and
• an interlocking unit including a vertical movement unit which is configured to move linearly in the Z-axis direction in conjunction with the main cam and a suction unit disposed at end portions of the vertical movement unit,
• wherein the vertical movement unit includes a first vertical movement member and a second vertical movement member which extend to a first side of the frame in an X-axis direction and a third movement member and a fourth vertical movement member which extend to a second side of the frame in the X-axis direction, and
• the main cam is configured to vertically move a diagonal pair of the vertical movement members of the vertical movement unit, which are disposed in a diagonal direction with the frame interposed therebetween, in a same direction, and
• wherein the interlocking unit further includes a horizontal movement unit which surrounds the vertical movement unit, the horizontal movement unit being configured to move in the Z-axis direction together with the vertical movement unit, and the frame has a horizontal guide slit assembly having a curved shape formed in the Z-axis direction of the frame that is configured to guide movement of the horizontal movement unit linearly in the X-axis direction independently of the vertical movement unit.
