In this embodiment, the soft-pack battery 100 can be firmly clamped between the flip plate 35 and the fixture seat 34.

[0046] In one embodiment, if Figure 6As shown in Figure 7, a storage space is provided between the liquid storage seat 343 and the support seat 344, and the storage space is used to accommodate the battery body of the soft-pack battery 100; the horizontal plate 352 is used to clamp the side bag of the soft-pack battery 100 on the liquid storage seat 343; the positive pole ear 102 and the negative pole ear 103 of the soft-pack battery 100 are both arranged on the battery body, and the injection hole 101 of the soft-pack battery 100 is arranged on the side bag. It can be understood that the positive pole ear 102 and the negative pole ear 103 are both arranged at the front end of the battery body, and the side bag is arranged on the side of the battery body. In this embodiment, the battery body is located in the storage space, the side bag is clamped between the vertical plate 353 and the liquid storage seat 343, and the positive pole ear 102 and the negative pole ear 103 are clamped between the horizontal plate 352 and the support seat 344; the battery fixture 3 has a compact structure and occupies a small space; further explained, the clamping assembly 2 is used to clamp the battery body.

[0047] In one embodiment, if Figure 8 and Fig.10 As shown, the injection valve 33 includes a sealing ring 331, a spring (not shown in the figure), a valve seat 332 provided with a third through hole 3321, and a valve core 333 provided with a valve hole 3331, and a side hole 3332 connected to the valve hole 3331 is provided on the side wall of the valve core 333, the sealing ring 331 and the spring are both sleeved on the valve core 333, the valve core 333 is slidably installed in the third through hole 3321, and the opposite ends of the spring are respectively connected to the valve seat 332 and the valve core 333; it can be understood that the spring is located in the third through hole 3321, the sealing ring 331 is located outside the through hole, and the outer diameter of the sealing ring 331 is greater than the inner diameter of the third through hole 3321.

[0048] The fixture seat 34 is also provided with a mounting hole connected to the liquid storage cavity 341, and the valve seat 332 is installed in the mounting hole; When the valve core 333 slides in the third through hole 3321 until the sealing ring 331 abuts against the valve seat 332, the side hole 3332 is not connected to the liquid storage chamber 341; specifically, the rebound force of the spring will drive the valve core 333 to move toward the outside until the sealing ring 331 abuts against the bottom of the valve seat 332, and the side hole 3332 is located inside the third through hole 3321. Since the sealing ring 331 blocks the third through hole 3321, the side hole 3332 is not connected to the liquid storage chamber 341, that is, the liquid storage chamber 341 is not connected to the external environment.

[0049] When the valve core 333 slides in the third through hole 3321 until the sealing ring 331 is away from the valve seat 332, the valve hole 3331 is connected to the liquid storage chamber 341 through the side hole 3332. Specifically, when the external connector is connected to the injection valve 33, the external connector will drive the valve core 333 to move in the third through hole 3321, and the sealing ring 331 is away from the valve seat 332. At this time, the valve hole 3331 is connected to the liquid storage chamber 341 through the side hole 3332, so that the external injection device can input electrolyte into the liquid storage chamber 341 through the injection valve 33. In this embodiment, the injection valve 33 has a simple structure and low manufacturing cost.

[0050] In one embodiment, the soft-pack battery carrier further includes a vacuum interface (not shown in the figure) mounted on the box body 1, and the vacuum interface is connected to all the receiving holes 11. It can be understood that an external vacuum pump can be connected to all the receiving holes 11 through the vacuum interface, so that the external vacuum pump can pump the receiving holes 11 into a positive pressure state or a negative pressure state through the vacuum interface. For example, when the soft-pack battery 100 is in a shelving state, the receiving holes 11 are pumped to a positive pressure or a negative pressure state, thereby completing the positive pressure shelving and negative pressure shelving of the soft-pack battery 100.

[0051] In one embodiment, if Figure 1 and Figure 6 As shown, the battery jig 3 includes a sealing ring 37 sleeved on the jig seat 34, and the sealing ring 37 is used to seal the outlet of the receiving hole 11. It can be understood that when the battery jig 3 is installed in the receiving hole 11, the sealing ring 37 abuts against the edge of the outlet of the receiving hole 11, so that the sealing ring 37 ensures the sealing of the battery jig 3 installed in the receiving hole 11.

[0052] To further illustrate, the soft-pack battery carrier provided in one embodiment of the present invention reduces the process complexity of the battery from baking, filling, shelving to formation, and saves the auxiliary mechanisms and transfer time between the processes. The heating element 22, formation electrodes (positive electrode assembly 31 and negative electrode assembly 32), liquid storage chamber 341, liquid filling valve 33, accommodating hole 11 and other designs of the soft-pack battery carrier make it possible to complete all the above processes without taking the soft pack out of the battery fixture 3; thereby improving equipment efficiency and reducing factory and equipment costs.

[0053] like Fig.12 As shown, another embodiment of the present invention further provides a battery manufacturing method, which is applied to the above-mentioned soft-pack battery carrier, comprising: S100, the flip plate 35 clamps the soft-pack battery on the fixture seat 34, and the injection hole 101 of the soft-pack battery 100 is connected to the liquid outlet interface 342, and the positive electrode ear 102 and the negative electrode ear 103 of the soft-pack battery 100 are electrically connected to the positive electrode assembly 31 and the negative electrode assembly 32 respectively; specifically, the flip plate 35 is rotated until the locking hook 351 is locked with the locking member 36, so that the clamping plate 21 can lock the soft-pack battery 100 on the fixture seat 34.

[0054] S200, the battery fixture 3 is installed in the receiving hole 11, and the clamp 21 clamps the opposite sides of the soft-pack battery 100; specifically, the clamping assembly 4 opens the clamp 21, and then installs the battery fixture 3 in the receiving hole 11, the clamping assembly releases the clamp 21, and the clamp 21 clamps the soft-pack battery 100 through the first heating plate 221 and the second heating plate 222.

[0055] S300, the inner cavity of the soft-pack battery 100 is evacuated through the liquid injection valve 33, and the soft-pack battery 100 is heated by the heating element 22; it can be understood that the liquid storage cavity 341 and the inner cavity of the soft-pack battery 100 are evacuated into a vacuum state, and the soft-pack battery 100 is heated, so that the moisture in the liquid storage cavity 341 and the soft-pack battery 100 can be removed, thereby completing the baking process of the soft-pack battery 100.

[0056] S400, after the soft-pack battery 100 is cooled in the receiving hole 11 for the first preset time, the electrolyte is injected into the liquid storage chamber 341 and the inner cavity of the soft-pack battery 100 through the injection valve 33; it can be understood that the first preset time can be set according to actual needs; after the soft-pack battery 100 is baked, the vacuuming of the liquid storage chamber 341 is stopped, and the heating of the soft-pack battery 100 is stopped; then, the soft-pack battery 100 is subjected to a cooling process, and after the soft-pack battery 100 is cooled, the soft-pack battery 100 is subjected to a liquid injection process; during the liquid injection process of the soft-pack battery 100, the external liquid injection pump can inject the electrolyte into the liquid storage chamber 341 through the injection valve 33, and the electrolyte in the liquid storage chamber 341 can flow into the inner cavity of the soft-pack battery 100 through the liquid outlet interface 342. Further, in order to accelerate the absorption of the electrolyte by the soft-pack battery 100, the heating element 22 can heat the soft-pack battery 100. To further illustrate, after the soft-pack battery 100 is filled with liquid, the liquid storage chamber 341 still has electrolyte, so that during the subsequent storage, formation and other process stages of the soft-pack battery 100, the electrolyte in the liquid storage chamber 341 can also flow into the soft-pack battery 100 to replenish the electrolyte of the soft-pack battery 100, so that the soft-pack battery 100 has sufficient electrolyte, thereby ensuring the performance of the soft-pack battery 100.

[0057] S500, after heating the soft-pack battery 100 in the receiving hole 11 by the heating element 22 for a second preset time, the soft-pack battery 100 is charged and discharged by the positive electrode assembly 31 and the negative electrode assembly 32; it can be understood that the second preset time can be set according to actual needs; when the soft-pack battery 100 is in the shelving stage, the soft-pack battery 100 is heated by the heating element 22 for a second preset time; after the soft-pack battery 100 is shelved, the soft-pack battery 100 is charged and discharged, thereby completing the formation process of the soft-pack battery 100.

[0058] S600, after the soft-pack battery 100 is charged and discharged in the receiving hole 11, the battery fixture 3 and the soft-pack battery 100 are taken out from the receiving hole 11. It can be understood that after the formation of the soft-pack battery 100 is completed, the charging and discharging of the soft-pack battery 100 is stopped; the clamping assembly 4 controls the clamping plate 21 to be in an open state, and the battery fixture 3 and the soft-pack battery 100 are taken out from the receiving hole 11. Further, after step S600, the flap 35 is opened from the fixture seat 34, and then the soft-pack battery 100 is removed from the fixture seat 34.

[0059] In the present invention, the soft-pack battery carrier can realize the steps of baking, cooling, liquid injection, shelving, and formation of the soft-pack battery 100, thereby improving the applicability and versatility of the soft-pack battery carrier.
