The lead screw penetrates the upper end of the clamping plate and is screwed, and one end of the lead screw is rotatably connected to the top of the pressing plate 1. The hand wheel is fixed on one end of the lead screw. When it is needed to clamp the battery pack 5, the lead screw is driven to translate the clamping plate to clamp the battery pack 5 by rotating the lead screw through the hand wheel.

[0062] The use method of the PACK whole package air tightness test compression structure is as follows:

[0063] Before testing, the battery pack 5 is placed on the top of the storage table 3, and then the storage table 3 is transported to the lower side of the pressing plate 1 by the AGV trolley 4, and then the lifting mechanism 2 drives the pressing plate 1 to descend, and the battery pack 5 is pressed between the pressing plate 1 and the storage table 3, and then the side clamps are used to press the side ends of the battery pack 5. After testing, the lifting mechanism 2 and the side clamps are restored to the state before testing, and then the AGV trolley 4 moves the battery pack 5 to the next process.
