As described in detail below.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a battery cell blanking device according to the present invention.
In an embodiment, the blanking device is applied to blanking the battery cell in the battery production process, the battery cell is formed by winding a pole piece on a winding needle 1 of a winding machine, and the blanking device applied to blanking the battery cell is used for blanking the battery cell wound on the winding needle 1.
The blanking device comprises a lifting component 2 and a blanking component 3. The lifting component 2 is arranged at the side of the winding needle 1. The blanking assembly 3 is positioned on one side of the lifting assembly 2 close to the winding needle 1. The blanking assembly 3 comprises a first end 31 and a second end 32 which are oppositely arranged at intervals, and at least the first end 31 is connected with the lifting assembly 2 in a sliding mode.
The spacing direction between the first end 31 and the second end 32 of the blanking assembly 3 is arranged along a first radial direction of the winding needle 1 (as indicated by arrow X in fig. 1, the same applies below). That is to say, the diameter design of the electric core that coils on the needle 1 is rolled up to unloading subassembly 3 of this embodiment, and be different from the length design that traditional unloading mechanism corresponds electric core, consequently this embodiment allows unloading subassembly 3 size in first radial direction to design littleer, thereby be favorable to improving the reliability and the stability of unloading subassembly 3, go on with the stability of guarantee electric core unloading, the problem that influence structural reliability and stability such as excessive downwarping has been avoided the unloading subassembly of traditional cantilever beam form to take place at the ascending size of first radial direction greatly.
In the present embodiment, the lifting unit 2 is disposed away from the moving path of the blanking unit 3. Specifically, unloading subassembly 3 is located the below of book needle 1, and elevating system 2 is located book needle 1 and the side of unloading subassembly 3. Therefore, the lifting assembly 2 can be prevented from occupying the space below the winding needle 1 and the moving space of the blanking assembly 3, so that the requirement on the setting height of the winding needle 1 can be reduced, and the design of the winding needle 1 can be more flexible.
Further, the blanking assembly 3 may be slidably connected to the lifting assembly 2 only at the first end 31, that is, the blanking assembly 3 is in a cantilever structure, and the second end 32 is a free end of the cantilever structure, as shown in fig. 1. Of course, in other embodiments of the present invention, the first end 31 and the second end 32 of the blanking assembly 3 can be slidably connected to a lifting assembly 2, respectively, without limitation.
Please continue to refer to fig. 1. In one embodiment, the lift assembly 2 includes a lift mounting plate 21, a lift drive 22, and a lift guide 23. The lifting mounting plate 21 is arranged beside the winding needle 1 and is parallel to the axial direction of the winding needle 1.

Note that the winding pin 1 is usually provided on a support plate 11. The extension face of the lifting mounting plate 21 is perpendicular to the extension face of the support plate 11, so that the operation space for battery cell blanking defined by the lifting mounting plate 21 and the support plate 11 is open, and the equipment installation and maintenance can be conveniently carried out by workers. In the conventional blanking mechanism, the mounting plate of the lifting component 2 is usually arranged opposite to the support plate 11 where the winding needle 1 is located, so that a worker must enter a space between the mounting plate of the lifting component 2 and the support plate 11 where the winding needle 1 is located to install and maintain equipment, and the worker is inconvenient to install and maintain the equipment.

The feeding assembly 5 is slidably supported on the second lifting guide 232 and connected to the second lifting driving member 222, and the second lifting driving member 222 is used for driving the feeding assembly 5 to move along the second lifting guide 232.
Alternatively, the first lifting driving member 221 and the second lifting driving member 222 may be screw rods, and nuts engaged with the screw rods are respectively disposed on the clamping assembly 4 and the feeding assembly 5. The screw rod is driven by a servo motor or a stepping motor and the like, and drives the material clamping assembly 4 to move along the first lifting guide 231 and the material feeding assembly 5 to move along the second lifting guide 232 through the matching between the screw rod and the nut.
Of course, in other embodiments of the present invention, the first lifting driving element 221 and the second lifting driving element 222 may also be in the form of an electric cylinder, a linear motor, a belt transmission mechanism, etc. to drive the material clamping assembly 4 and the material feeding assembly 5 to move toward or away from the winding needle 1.
It should be noted that in this embodiment, the material clamping assembly 4 and the material feeding assembly 5 are driven to move by different lifting driving members 22 and lifting guiding members 23, so that the movement control between the material clamping assembly 4 and the material feeding assembly 5 is independent and does not interfere with each other, and thus the positions of the material clamping assembly 4 and the material feeding assembly 5 can be adjusted more flexibly, so as to facilitate the development of the battery cell blanking operation.

Therefore, because the specifications of the battery cells formed by winding the winding needles 1 of different models are different, the material clamping assembly 4 of the embodiment can adjust the distance between the two sets of clamping jaw assemblies 42 according to the diameter of the battery cells, so that the two sets of clamping jaw assemblies 42 are matched with each other to clamp the battery cells, and therefore, the winding needles 1 of different models can be adapted to the battery cells, and the compatibility is good.
