[0027] Working principle:

[0028] like Figure 8 As shown, first, place the blister energy storage upper box cover 100 on the bottom module 2, and the raised part of the bottom module 2 is covered by the blister energy storage upper box cover 100. Adjust the limiting frames 2.2 on the four sides along the slide rail direction so that the limiting frames 2.2 are close to the edge 102 of the flange surface 101. After adjustment into place, lock the ends of the limiting frames 2.2 in the first direction lower adjustment groove 2.12 and the second direction lower adjustment groove 2.13 of the edge 2.11 by the locking bolts 2.3, so as to limit the edges of the blister energy storage upper box cover 100 in four directions.

[0029] like Figure 5 As shown, the top pressure frame 1 is then placed over the blister energy storage upper case cover 100. The top pressure strip 1.13 is adjusted using the adjusting bolts 1.3 so that all four sides of the top pressure strip 1.13 are pressed against the flange surface 101 of the blister energy storage upper case cover 100. The adjusting bolts 1.3 are then tightened against the top pressure strip 1.13 to secure the top pressure strip 1.13 in place. The adjustment bolts 1.3 can be moved to accommodate products of different sizes.

[0030] Figure 9 As shown, during the test, a downward pressing device is used to press on the top pressing frame 1, and the top pressing frame 1 descends. The flange surface 101 of the blister energy storage upper box cover 100 is pressed by the top pressing frame 1, and the internal support inflation module 3 is started. Air is inflated into the blister energy storage upper box cover 100 through the inflation port 2.15 to test whether the blister energy storage upper box cover 100 will leak.
