Sealing nail picking device

The utility model provides a sealing nail picking device. The sealing nail picking device comprises a vibration sorting assembly, a first transmission assembly and a picking mechanism. The vibration sorting assembly can adjust the sealing nails placed on the vibration sorting assembly to be in a first posture through vibration and convey the sealing nails to the first transmission assembly in sequence. The sealing nails in the first posture fall down from the vibration sorting assembly one by one, the carrier moves along the sliding part to change the position so as to receive the sealing nails falling down one by one, and the sealing nails falling into the carrier can be adjusted to be in the second posture and kept in the second posture; and the picking mechanism transmits the sealing nail in the second posture to a target position where a liquid injection hole of the battery cell is located, and transmits the sealing nail to be inserted into the liquid injection hole of the battery cell.
