[0057] When working, the battery A is placed on the conveying device 100, and the detection switch senses the signal to start the driving motor 112 to convey the battery A to the left end. When the upper detection switch 105 detects the signal, the transfer device 200 is started to move the battery A to the lower vacuum chuck 321 in the lower box 308 and adsorb it. Then the transfer cylinder 327 moves it to the leak detection position. Then the upper box lifting cylinder 314 presses the upper box 324 onto the lower box 308, and then the clamping plate cylinder 315 pushes the clamping plate 317 to clamp the clamping block 319 between the upper and lower jacks 320 and 318. Then the vacuum air path in the box is opened, and the pressure is maintained for a period of time. Then the mechanisms are reset in turn, the lower box 308 is moved back to the feeding position, and then the transfer device 200 is moved to the conveying device 100 for discharging. In order to improve efficiency, the above process is carried out in three sets of testing devices 300.
