[0061] At present, from the development of market situation, the application of power battery is more and more extensive. The power battery is not only applied to the energy storage power supply system of hydropower, thermal power, wind power and solar power station, but also widely applied to electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, military equipment, aerospace and other fields. With the continuous expansion of the application field of power battery, the market demand is also increasing.

[0062] The power battery generally includes a plurality of battery monomers, and the liquid injection and formation are important process flows in the processing of the battery monomers. The battery monomer includes a shell and an electric core in the shell, the shell is provided with a liquid injection hole, liquid is injected into the electric core through the liquid injection hole, and the shell is vacuum sealed after the electric core is injected with liquid. Then, the battery monomer is formed, and the formed battery monomer is transferred to a shelf for storage.

[0063] Based on the above considerations, in order to solve the problem that the battery monomer is prone to swelling due to internal gas residue during storage after formation, the present inventors have designed a stacking device through in-depth research. By integrating an exhaust position and an exhaust assembly on the stacking device, the battery monomer is first transferred to the exhaust position before being transferred to the shelf. The exhaust assembly is used to press the exhaust valve of the battery monomer, so that the gas in the battery monomer is discharged through the exhaust valve. Then, the stacking device is used to transfer the battery monomer to the shelf for storage, solving the problem of battery monomer swelling and improving the safety of the battery monomer during storage on the shelf.

The driving member 2 is in transmission connection with the base body 1 to drive the base body 1 to move along a first direction towards or away from the exhaust position 10. The exhaust assembly 3 is arranged on the base body 1 and corresponds to the exhaust position 10; wherein when the battery monomer 100 after formation is carried to the exhaust position 10, the exhaust assembly 3 can be driven by the driving member 2 to move towards the exhaust position 10 along with the base body 1 to press the exhaust valve 110 on the battery monomer 100 aligned therewith, so that the gas in the battery monomer 100 is discharged through the exhaust valve 110. The first direction generally refers to the up-down direction, specifically as shown by the arrow Z in Figure 1 .

When the battery monomer 100 is placed in the exhaust position 10, one end provided with the exhaust valve 110 faces upward, so as to facilitate the downward movement of the exhaust assembly 3 to press the exhaust valve 110. Specifically, the exhaust valve 110 includes a valve body 112 and a valve core 111. In the closed state of the exhaust valve 110, the valve core 111 extends out of the valve body 112, and the exhaust assembly 3 opens the exhaust hole of the exhaust valve 110 by pressing the valve core 111 into the valve body 112.

When the servo motor 441 rotates, the fork 42 will slide up and down along the portal frame 43 through the transmission belt 443, thereby realizing the position adjustment of the battery monomer 100 on the fork 42 in the first direction.

[0074] Optionally, the carrying device 4 can carry multiple battery monomers 100 at a time, and the multiple battery monomers 100 carried at a time are placed in the tray 200. The carrying device 4 carries the multiple battery monomers 100 by lifting the tray 200, and stacks the battery monomers 100 and the tray 200 on the shelf 6.

[0075] Specifically, the tray 200 can accommodate multiple rows and columns of battery monomers 100, and the exhaust assembly 3 can simultaneously press and exhaust the multiple rows and columns of battery monomers 100.

[0081] It should be noted that the driving member 2 is not limited to the above structure, and the driving member 2 can also adopt a gas cylinder or a motor lead screw module, which can drive the base body 1 to move in the first direction.

[0082] Please continue to refer to Figure 5 The exhaust assembly 3 includes a connecting member 31 and a plurality of probes 32. The connecting member 31 is mounted on the base body 1 and includes a plurality of supporting arms 311. Each probe 32 is arranged at the end of each supporting arm 311. By arranging a plurality of supporting arms 311 corresponding to the probes 32, the probes 32 are supported to facilitate the installation of the probes 32 to the position opposite to the corresponding battery monomer 100.

[0083] In some embodiments, in combination Figure 2As shown, each probe 32 comprises a needle portion 321 which opens the exhaust hole of the exhaust valve 110 when pressing against the exhaust valve 110; the needle portion 321 is provided with a first through hole which is in communication with the exhaust hole of the exhaust valve 110.

[0084] Correspondingly, the second through hole is provided in the support arm 311 and is in communication with the first through hole of the needle portion 321, so as to further guide the gas discharged by the exhaust valve 110.

[0087] In some embodiments, the exhaust assembly 3 further comprises an exhaust pipeline 33, one end of which is in communication with the first through holes of the plurality of probes 32, and the other end is in communication with the outside. In this way, the gas in the first through hole is discharged to the outside through the exhaust pipeline 33, preventing the gas discharged by the battery monomer 100 from spreading in the workshop environment.

[0088] Specifically, the exhaust pipeline 33 is in communication with the second through hole of the support arm 311, so as to be in communication with the probe 32 through the support arm 311.

[0089] In some embodiments, the exhaust pipeline 33 is provided with a sub-pipeline 331 which is retractable in the first direction. By the retractable sub-pipeline 331, the length of the exhaust pipeline 33 can be adjusted to improve the installation flexibility of the exhaust pipeline 33.

[0090] In some embodiments, the exhaust assembly 3 further comprises a vacuum pump 34 provided on the exhaust pipeline 33, and the vacuum pump 34 is used to generate negative pressure in the exhaust pipeline 33. By providing the vacuum pump 34, the gas discharged by the battery monomer 100 is accelerated to be discharged to the outside through the exhaust pipeline 33.

[0091] Please continue to refer to Figure 5In some embodiments, the base 1 comprises a mounting portion 11 for mounting the probe 32 and a plurality of support portions 12.

The plurality of support portions 12 are arranged at intervals, and an avoidance space for the battery monomer 100 to enter and exit is defined between any two adjacent support portions 12. The mounting portion 11 facilitates the mounting of the probe, and the mounting portion 11 and the plurality of support portions 12 jointly define the exhaust position 10. The plurality of support portions 12 are arranged at intervals, so that the fork 42 can pass between any two adjacent support portions 12 to transport the battery monomer 100 to the exhaust position 10.

[0092] Specifically, the mounting portion 11 is arranged in a quadrilateral plate structure, and the four support portions 12 are arranged at the four corners of the mounting portion 11. The fork 42 can move along the arrangement direction of the plurality of battery monomers 100 and pass between any two support portions 12 to enter above the positioning platform 5.
