the left side of the lower cutter 5 is provided with a battery cell shell body placing groove 51 for placing the shell body part 31 of the battery cell 30 which needs to be subjected to the outer edge aluminum-plastic film part corner cutting operation.
It should be noted that, according to the present invention, the upper cutter holder 3 and the upper cutter 4 can move up and down in the vertical direction under the driving of the cylinder 2, so as to achieve the cutting operation of the aluminum-plastic film portion of the battery cell 30, specifically, the corner cutting operation of the aluminum-plastic film portion 32 of the battery cell.
With the present invention, the shape and size of the battery cell housing placement groove 51 are matched with the shape and size of one corner of the housing portion 31 of the battery cell 30, which is required to be subjected to the corner cutting operation. Therefore, the invention removes the part interfering with the shell body of the battery cell by arranging the battery cell shell body placing groove 51, and innovatively improves the structure of the lower cutter 5.
For the present invention, it should be noted that the battery core 30 that needs to be subjected to the corner cutting operation is a rectangular, soft-package battery core, most of which is a casing part 31, the front and back sides of the casing part 31 of the battery core are provided with aluminum-plastic film parts 32 with outer edges (especially, the front and back ends of the long side of the casing are provided with aluminum-plastic film parts with more outer edges, so that necessary cutting operation needs to be performed to meet the requirements of the battery core assembly and the user), and the corner cutting operation is performed on the aluminum-plastic film part that cannot start the power supply function of the battery.
In the specific implementation, the thickness of the shell portion 31 of the electrical core is greater than the height of the aluminum-plastic film portion 32, and the aluminum-plastic film portion and a side surface (top surface or bottom surface) of the shell portion of the electrical core are in the same plane, when a corner (a corner of a circular arc shape shown in fig. 2 and 3) of the shell portion 31 of the electrical core is placed in the electrical core shell placing groove 51, the aluminum-plastic film portion on the outer edge of the corner is just located in the gap between the upper cutter 4 and the lower cutter 5, so that the corner cutting operation can be performed, as shown in fig. 2 and 3, there are aluminum-plastic film portions 32 before and after the corner cutting.
