Adsorption apparatus

An adsorption device for adsorbing battery cells loaded in a loading bin and sequentially removing and transporting the battery cells, comprising:

• a base plate arranged to move vertically and horizontally;
• a suction unit coupled to the base plate for adsorbing a battery cell located at a lower part of the base plate;
• and
• a push unit coupled to the base plate for striking the battery cell to produce a vibration in the battery cell adsorbed by the suction unit, wherein
• the push unit comprises a rod that is lifted up and down and configured to strike a top surface of the adsorbed battery cell to a lower end part thereof, wherein
• the rod descends by elastic force of a spring member, wherein
• the push unit comprises:
• a cylinder coupled to the base plate, and having an open bottom;
• the rod inserted into the cylinder to linearly reciprocate along a longitudinal direction of the cylinder;
• and
• the spring member, each end of which is coupled to the cylinder and the rod, respectively, and which pushes the rod downwardly,
• the cylinder comprises:
• a plurality of teeth parts, each comprising a protruding tooth blade to have a unidirectional slope along a perimeter of an inner side;
• and
• a groove part downwardly recessed between any one pair of teeth parts, and
• the rod comprises:
• a moving blade protruding from one side of an outer circumferential surface to engage and disengage to the teeth part of the cylinder.
