Thus, when the battery cell 1 is placed between the supporting surface 431 and the bending surface 231 in the middle, the supporting surface 431 can support one side portion of the whole battery cell 1 in a wide range; the bending surface 231 can concentrate the bending pressure on the two tabs 2; in the process that the cutter 330 moves from top to bottom, the inclined cutting surface 331 can gradually apply pressure to the tab 2 with a smaller contact area, so that the cutting pressure is high, and the cutting is easier to perform.

The working principle of the bending and cutting integrated device in the embodiment is specifically described below. In this embodiment, the driving bases 510 on the left and right sides move synchronously under the driving of the driving device 520, and the driving bases 510 have a first driving position (fig. 2) and a second driving position (fig. 1) on the base 100, and the first driving position is located at the front side of the second driving position; the driving base 510 further has a third driving position (not shown) when moving from the first driving position to the second driving position.

At this time, the supporting platform 430 is located at the lowest position, the bending block 230 and the cutting knife 330 are located at the highest positions, respectively, the bending surface 231 and the supporting surface 431 are arranged at an interval in the vertical direction Z, the cutting surface 331 and the supporting surface 431 are arranged at an interval in the vertical direction Z, the bending surface 231 and the cutting surface 331 are both located above the supporting surface 431, and the bending surface 231 is located below the highest point in the middle of the cutting surface 331. At this time, the battery cell 1 with the tab 2 may be transported by the carrier 3, and the tab 2 horizontally extends backward along the front-back direction X and is defined between the bending surface 231 and the supporting surface 431.

Referring to fig. 3 and 4, subsequently, the driving unit 520 drives the driving base 510 to move backward gradually, in the process, the first guiding post 220 slides forward and downward along the first inclined slot 511a, the second guiding post 320 slides forward and downward along the second driving slot 512, the third guiding post 420 slides forward and upward along the third inclined slot 513a, so as to drive the bending block 230 and the cutting knife 330 to descend gradually, the supporting platform 430 ascends gradually, and the supporting surface 431 and the bending surface 231 contact the tab 2 before the cutting surface 331. In some embodiments, the support surface 431 will contact the tab 2 before the bending surface 231, and thereafter the support surface 431 and the tab 2 are kept stationary and stably supported below the tab 2. The sequence of the contact of the support surface 431 and the bending surface 231 with the tab 2 is related to the specific shapes of the first driving groove 511 and the third driving groove 513 and the initial position of the tab 2. When the driving seat 510 is located at the third driving position, the bending surface 231 abuts against the supporting surface 431, and the cutting surface 331 is located above the supporting surface 431. At this time, the bending surface 231 and the support surface 431 exert pressure together to bend the tab 2.

Thereafter, as the driving base 510 continues to move backward, the first guiding column 220 horizontally slides forward along the first flat slot 511b, the third guiding column 420 horizontally slides forward along the third flat slot 513b, and the up-down positions of the supporting surface 431 and the bending surface 231 are not changed any more; and the second guiding column 320 continues to slide forward and downward along the second driving groove 512, so that the cutting surfaces 331 continue to descend until the tab 2 is contacted and cut, and the left and right cutting surfaces 331 are respectively used for cutting the tab 2 on the same side.

Referring to fig. 1 and 6, when the driving seat 510 is located at the second driving position, the bending surface 231 abuts against the supporting surface 431, the cutting knife 330 is located at the rear side of the supporting surface 431, at least a part of the cutting surface 331 is located below the supporting surface 431, the cutting knife 330 abuts against the supporting table 430 along the front-back direction X, the excess tab 2 is completely cut off, and the cutting process is completed.

After the bending and cutting process of a group of tabs 2 is completed, the driving device 520 can drive the driving base 510 to move forward and return to the first driving position, so that the tabs 2 are released, the corresponding battery cells 1 can be transmitted away by the carrying platform 3, the next battery cells 1 to be processed are transmitted, and then the next round of bending and cutting is performed.

To sum up, the bending and cutting integrated device provided by the embodiment only needs one driving device 520, and can drive the orderly lifting of three groups of mechanisms, namely the bending mechanism 200, the cutting mechanism 300 and the supporting mechanism 400, so that the bending and cutting of the tab 2 are sequentially completed, the device cost is obviously reduced, the occupied space of the device is reduced, the labor is saved, and the process efficiency is improved.
