[0057] The cutting device provided in the application can realize the following steps:

[0058] Battery conveying: first, place the battery 2 downward into the belt line 1, then convey through the belt line 1, after reaching the fixed position, the conveying mechanism 3 starts to work, the second driving motor 35 on the conveying rack 31 starts to work, so that the second mechanical gripper 32 moves on the conveying track 37, after reaching the fixed position, the second gripping telescopic assembly 33 starts to work, driving the second mechanical gripper 32 to move downward, then after reaching the fixed position, the second mechanical gripper 32 grips the battery 2, after the second mechanical gripper 32 grips the battery 2, the second gripping telescopic assembly 33 starts to move upward, after reaching the fixed position, then the second driving motor 35 starts to work, moving the second mechanical gripper 32 above the cutting mechanism 5, the second mechanical gripper 32 starts to rotate by 90 degrees, then the second gripping telescopic assembly 33 starts to work again, the second mechanical gripper 32 moves downward, after reaching the fixed position, the second mechanical gripper 32 releases the battery 2, and places the battery 2 between the first positioning piece 56 and the second positioning piece 58, after the above operation is completed, the second driving motor 35 starts to work, moving the second mechanical gripper 32 to the standby position, and waiting for operation.

[0059] Battery cutting: After the battery 2 is placed between the first positioning member 56 and the second positioning member 58, the first clamp jaw 54 and the second clamp jaw 55 are activated to press the battery 2 tightly. After the battery 2 is fixed by being pressed tightly, the first limiting member 512 and the second limiting member 513 are activated to drive the second cutting mechanism 514 and the third cutting mechanism 515 to rotate to the cutting position, and then the second cutting knife 510 on the second cutting mechanism 514 and the third cutting knife 511 on the third cutting mechanism 515 start to move and cut, respectively cutting the packaging member 72 on both sides of the second side 75 and the fourth side 76 of the battery 2. At the same time, the telescopic member 52 on the first rack 51 starts to extend and retract, driving the first cutting knife 53 above the battery to cut the packaging member 72 on the third side 73 of the battery 2. After the cutting is completed, the first limiting member 512 and the second limiting member 513 drive the second cutting mechanism 514 and the third cutting mechanism 515 to rotate to the waiting position, and the first driving member 57 drives the first positioning member to flip away from the second positioning member 58, and the second driving member 59 is used to drive the second positioning member to flip away from the first positioning member, so as to drive the two battery cells 71 in the battery to unfold.
