The missing air can be sucked in through the negative pressure suction nozzle 313. When the battery is placed on the support seat 312, the negative pressure suction nozzle 313 is blocked by the battery, so the negative pressure can tightly adsorb the battery on the vacuum manifold 311, thereby achieving adsorption and fixation of the battery.
