[0045] In some embodiments, the detection device further includes a device body 5; the snap-fit ​​component 22 is adapted to move the left sealing component 11 and the right sealing component 12 closer and further away, the left sealing component 11 and the right sealing component 12 seal the battery casing when they are close together, and the left sealing component 11 and the right sealing component 12 move away from each other to facilitate the removal and placement of the battery casing; the gas supply mechanism 4 is adapted to supply gas to the left sealing component 11 and / or the right sealing component 12.

[0046] In some embodiments, the left sealing assembly 11 is fixedly connected to the device body 5; the left sealing assembly 11 is connected to the gas supply mechanism 4 and is used to provide high-pressure gas into the sealed battery casing cavity; the right sealing assembly 12 is connected to the snap-fit ​​assembly 22 to push the right sealing assembly 12 closer to the left sealing assembly 11.

[0047] In some embodiments, both the left sealing assembly 11 and the right sealing assembly 12 include a first plate 13 adapted to press against the end of the battery casing and a second plate 15 fitted onto the end of the battery casing, wherein the first plate 13 presses against the battery casing to achieve a seal on the battery casing.

[0048] In some embodiments, the second plate 15 and the first plate 13 are connected by a connecting shaft so that they move together under the action of the snap-fit ​​assembly 22; the first plate 13 is adapted to snap into the snap-fit ​​assembly 22.

[0049] In some embodiments, the first plate 13 is provided with an insert 14 for inserting into the end of the battery casing, for direct insertion into the hollow portion of the end of the battery casing; the second plate 15 is provided with a through hole 16 for fitting the battery casing, for avoiding interference with the battery casing, and for further sealing the battery casing by pressing the battery casing when the second plate 15 moves outside the insert 14; the snap-fit ​​assembly 22 includes a module, a cylinder, a snap-fit ​​component, and a mounting base; the snap-fit ​​component is connected to the push rod of the cylinder, the cylinder is located on the mounting base, and the mounting base is connected to the module through a connecting part; after the cylinder pushes the snap-fit ​​component to snap into the first plate 13, the module is adapted to pull the second plate 15 and the first plate 13 forward, so that the left sealing assembly 11 and the right sealing assembly 12 move closer and further away.

[0050] In some embodiments, the pulling mechanism 2 further includes a guide 23 connected to the device body 5; the guide 23 passes through the mounting seat of the snap-fit ​​assembly 22 for guiding it; the push rod of the cylinder 21 is connected to the second plate 15 to push the second plate 15 closer to the first plate 13 for further sealing the end of the battery casing.

[0051] Working Principle: Before using a battery casing testing device, an external transport mechanism places the battery casing to be tested at the positioning and sealing mechanism 1. During this process, the battery casing is inserted into the left sealing assembly 12 or the right sealing assembly 13, thus beginning the sealing of the battery casing. Under the control of the external control system, the snap-fit ​​assembly 22 operates, pushing the left sealing assembly 12 and the right sealing assembly 13 closer together. During this process, the inserts 14 of the two first plates 13 are inserted into the hollowed-out portions at both ends of the battery casing, at which point the battery casing is initially sealed. Then, under the control of the external control system, the hydraulic cylinder 21 starts to operate, pushing the two second plates 15 to move. During this process, the second plates 15 move relative to the battery casing until the second plates 15 contact the first plates 13, at which point the second plates 15... Hole 16 is located outside the insert 14 and presses against the end of the battery casing to achieve a better sealing effect. Furthermore, the external control system supplies air to the first plate 13 via the air supply mechanism 4. High-pressure gas enters the battery casing through the hole in the middle of the insert 14 of the first plate 13. The process stops after a certain amount of gas has been introduced. Further, under the control of the external control system, the lifting water tank mechanism 3 rises, so that the entire battery casing is below the water surface in the tank. Observe whether any bubbles are generated at this time. If bubbles are generated, it proves that the battery casing's sealing performance is unqualified; if no bubbles are generated, it proves that the battery casing's sealing performance is qualified. After maintaining this position for a period of time, all parts are reset. The external transport mechanism places the inspected battery casing in the required position and places a new battery casing, repeating the above process until the work is completed.
