[0030] Moreover, the air valve 8 is installed on the upper mold base 7 and is connected in conjunction with the air tightness detector 3, so that the air tightness detector 3 can automatically perform air tightness detection on the battery 4 between the upper mold base 7 and the lower mold base 5 through the air valve 8, so as to effectively avoid a series of problems such as low detection efficiency, large error rate and high cost caused by manual operation.

[0031] Furthermore, the testing work area between the upper positioning plate 1 and the lower positioning plate 2 of the frame is also equipped with an opening and closing protective door or a mis-touch detector to effectively prevent equipment damage or user injury caused by foreign objects or users entering the testing work area during battery 4 airtightness testing. In addition, the opening and closing protective door can also prevent dust from entering, which not only further improves the stability and accuracy of battery 4 airtightness testing, but also facilitates daily equipment maintenance and is highly practical.

[0032] The lower positioning plate 2 is provided with a mold base plate 9 and adjusting bolts 10. Several adjusting bolts 10 are provided and are adjustablely arranged on the lower positioning plate 2. The several adjusting bolts 10 are evenly distributed at intervals corresponding to the outer shape of the mold base plate 9. The mold base plate 9 is adjustablely installed and positioned on the lower positioning plate 2 by the several adjusting bolts 10.

[0033] In this embodiment, several adjusting bolts 10 are arranged horizontally and rotated threadedly toward the mold base plate 9 to achieve position adjustment. When the user needs to remove the mold base plate 9, the adjusting bolts 10 acting on the periphery of the mold base plate 9 can be loosened. When the user needs to assemble the mold base plate 9, the adjusting bolts 10 can be applied to the periphery of the mold base plate 9. The positions of the adjusting bolts 10 can also be adjusted to achieve adjustment of the assembly position of the mold base plate 9.

[0034] The mold base plate 9 is provided with a number of positioning pins 11, which are respectively installed and removed from the mold base plate 9. The number of positioning pins 11 are evenly distributed at intervals corresponding to the outer shape of the lower mold base 5. The lower mold base 5 is positioned on the mold base plate 9 by the installation and removal of the number of positioning pins 11.

[0035] In this embodiment, several positioning pins 11 are longitudinally disassembled and installed on the mold base plate 9. The lower mold base 5 is positioned between several positioning pins 11 by longitudinal disassembly and installation. The disassembly and installation method is quick and convenient, and there will be no left-right shaking or swaying after assembly, resulting in high stability.

[0036] Since the mold base plate 9 and the lower mold base 5 can be disassembled and assembled, users can perform airtightness testing on batteries 4 of different sizes and specifications, making it widely applicable.

[0037] The mold base plate 9 and / or the lower mold base 5 are also provided with disassembly handles 12.

[0038] In this embodiment, the disassembly handle 12 is provided on the mold base plate 9. The mold base plate 9 can be disassembled and mounted on the lower positioning plate 2 through the disassembly handle 12 for user convenience.

[0039] The lower mold base 5 is provided with a lower sealing ring 13 corresponding to the bottom surface of the battery 4, and the upper mold base 7 is provided with an upper sealing ring 14 corresponding to the surface of the battery 4.

[0041] In this embodiment, when the lower mold base 5 and the upper mold base 7 press the battery 4 together, the lower sealing ring 13 and the upper sealing ring 14 can seal the side of the channel on the battery 4 respectively, so that the channel of the battery 4 can only communicate with the outside air through the channel hole 15. In addition, since the channel hole 15, the lower airtightness detection hole 16, and the upper airtightness detection hole 17 correspond to each other, and the air valve 8 is set on the upper airtightness detection hole 17, the airtightness detector 3 can pressurize or depress air in the direction of the channel hole 15, the lower airtightness detection hole 16, and the upper airtightness detection hole 17 through the air valve 8, so that air enters the channel of the battery 4, thereby realizing the airtightness detection of the battery 4.

[0042] The upper positioning plate 1 and the lower positioning plate 2 are arranged vertically, and a positioning post 18 is provided between them. The upper positioning plate 1 and the lower positioning plate 2 are positioned vertically by the positioning post 18.

[0043] In this embodiment, the bottom surface of the upper positioning plate 1 and the surface of the lower positioning plate 2 are respectively provided with assembly seats. The positioning column 18 extends longitudinally and its upper and lower ends are respectively connected to the assembly seats on the bottom surface of the upper positioning plate 1 and the surface of the lower positioning plate 2, thereby realizing the assembly of the upper positioning plate 1, the positioning column 18 and the lower positioning plate 2.

[0044] The upper positioning plate 1 is provided with a guide hole 19, and the upper mold base 7 is provided with a guide post 20. The guide post 20 is fixed longitudinally on the upper mold base 7 and moves longitudinally through the guide hole 19.

[0049] In this embodiment, when the upper mold base 7 is far away from the lower mold base 5 and the locking hole of the locking tongue 22 is aligned with the locking hole of the locking member 23, the locking disengagement part of the locking drive member 24 acts on the locking hole and the locking hole, so that the locking tongue 22 is locked on the locking member 23, thereby locking the upper mold base 7, so that the user can safely disassemble and assemble the mold base plate 9, the lower mold base 5, and the battery 4. When the locking disengagement part of the locking drive member 24 leaves the locking hole and the locking hole, the upper mold base 7 is in the unlocked state, and the driver 6 can drive the upper mold base 7 to achieve longitudinal reciprocating movement.

[0050] In this embodiment, the frame is assembled from several profiles, with side panels installed at the top and bottom of the profiles, forming an upper cabinet 26 and a lower cabinet 27. An upper positioning plate 1 is fixed to the upper cabinet 26, and a lower positioning plate 2 is fixed to the lower cabinet 27. An airtight detector 3 is fixed to the upper cabinet 26.
