[0049] Frame 1;

[0050] Positioning fixture 2 is slidably connected to frame 1 and is used to fix battery tray 5;

[0051] The positioning fixture 2 is equipped with a U-shaped sealing plate 21, which is made of aluminum plate. Aluminum plate can be repeatedly stretched and is not easy to break, which greatly improves the service life of U-shaped sealing plate 21. Sealing strips 211 are provided around the U-shaped sealing plate 21, which can make U-shaped sealing plate 21 and battery tray 5 tightly connected. Several first pressing mechanisms 22 are provided on both sides of U-shaped sealing plate 21. The output end of the first pressing mechanism 22 is connected to U-shaped sealing plate 21, which can drive the sealing plate to be tightly connected to battery tray 5.

[0052] The drive mechanism 3 has its output end connected to the positioning fixture 2, which can drive the positioning fixture 2 to reciprocate on the frame 1. The drive mechanism 3 is driven by a cylinder.

[0053] The second pressing mechanism 4 is located above the positioning fixture 2 and connected to the frame 1, and is used to press the battery tray 5 onto the positioning fixture 2.

[0054] Furthermore, such as Figure 2 , 4 As shown in Figures 1 and 10, in this embodiment, the positioning fixture 2 is also provided with 23 and several sealing mechanisms 24;

[0055] 23 is set inside the U-shaped sealing plate 21 to support the battery tray 5;

[0056] Several sealing mechanisms 24 are provided on the other two sides of the U-shaped sealing plate 21 to seal the air leakage holes of the battery tray 5.

[0057] Furthermore, such as Figure 4 As shown, in this embodiment, the sealing mechanism 24 includes a sealing cylinder 241 and a sealing block 242; the output end of the sealing cylinder 241 is connected to the sealing block 242, and the sealing cylinder 241 can drive the sealing block 242 to move; a sealing rubber component is provided on the sealing block 242 to improve the sealing performance.

[0058] Furthermore, such as Figure 2As shown, in this embodiment, the first pressing mechanism 22 includes:

[0059] The first pressing cylinder 221 has a first pressing plate 222 at its output end;

[0060] The first clamping plate 222 is connected to the U-shaped sealing plate 21.

[0061] Furthermore, such as Figures 1-5 As shown, in this embodiment, the second clamping mechanism 4 includes:

[0062] Several second clamping cylinders 41 are connected to the frame 1;

[0063] The first clamping frame 42 is connected to the output end of the second clamping cylinder 41;

[0064] Several second clamping plates 43 are connected to the first clamping frame 42 via several connecting columns.

[0065] Furthermore, such as Figures 1-5 As shown, in this embodiment, the second pressing mechanism 4 further includes: a plurality of elastic pressing components 45, which are arranged around the first pressing frame 42 for pressing the battery tray 5.

[0080] Working principle: First, the battery tray 5 is placed on the positioning fixture 23; then, the drive mechanism 3 drives the positioning fixture 2 to move below the first clamping frame 42, and the second clamping cylinder 41 drives the first clamping frame 42 to descend until the second clamping plate 43 and the third clamping plate 4521 clamp the battery tray 5; then, the first press cylinder pushes the U-shaped sealing plate 21 to clamp the battery tray 5, and the sealing cylinder 241 drives the sealing block 242 to seal the air leakage holes at the other two ends of the battery tray 5, so that a sealed cavity is formed between the U-shaped sealing plate 21 and the battery tray 5; then, air is injected into the battery tray 5 to start the airtightness test.
