The diameter of the inner groove wall of the annular groove 341 is smaller than the inner diameter of the battery case at the first end of the battery, and the diameter of the outer groove wall of the annular groove 341 is larger than the outer diameter of the battery case at the first end of the battery.
It should be noted that, the flanging device shown in this embodiment may be provided in plurality, and the first flanging device, the second flanging device, …, the N-1 th flanging device, and the N-th flanging device are sequentially arranged along the direction of the X axis according to the sequence of flanging the first end of the battery, where N is a natural number greater than or equal to 1, and the first flanging device, the second flanging device, …, the N-1 th flanging device, and the N-th flanging device are sequentially arranged at each flanging sealing station.
In order to ensure the flanging effect on the first end of the battery, the embodiment specifically sets the groove depth of the annular groove on the nth flanging device to be greater than the groove depth of the annular groove on the N-1 th flanging device. Thus, the groove depth of the annular groove 341 of the upper press head of each flanging device is gradually increased along the sequencing direction of each flanging sealing station. Therefore, the flanging device at each station can be used for sequentially performing first flanging treatment, second flanging treatment, … and Nth flanging treatment on the first end of the battery. After the first end of the battery is sequentially subjected to the Nth flanging treatment, the first end of the battery can be turned over for 180 degrees towards the inner side of the battery.
As shown in fig. 7, in the sealing device, since the operation surface 340 of the upper ram of the sealing device is flat, when the first telescopic driving mechanism 32 drives the ram 34 to move toward the first end of the battery, the first end of the battery after the crimping process can be sealed.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
