For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
Referring to fig. 1, fig. 1 is a flow chart of an embodiment of a method for blanking a battery cell according to the present application. In this embodiment, the method for blanking a battery cell includes:
in step S11, the inner wall of the wound cell is supported by the support portion. The number and shape of the supporting parts can be adjusted according to actual needs, for example, only one supporting part is suitable, or more supporting parts are used. Specifically, please further refer to fig. 2-5. The method comprises the following substeps:
in step S111, the support 12 is extended into the inner cavity of the cell 11 in a direction parallel to the axis of the cell 11. If the support 12 moves in a direction not parallel to the axis of the cell 11, it is easy to scratch the inner cavity of the cell 11, thereby causing the membrane to wrinkle.
In step S112, the support 12 is moved upward in a direction perpendicular to the axis of the cell 11 until a portion thereof abuts against the inner wall of the cell 11. Generally, the support 12 will extend into the middle of the cavity of the cell 11 to prevent it from scratching the cavity of the cell 11. And when the electric wire stretches into the inner cavity of the battery cell 11, the electric wire does not contact with the inner cavity of the battery cell 11, so that the electric wire cannot play a supporting role. Therefore, the battery cell 11 needs to be moved again, and can be abutted against the inner wall to perform a supporting function.
In step S12, the cells 11 are flattened. During the flattening, the cell 11 may be pressed down and flattened by starting the pressing from above the cell 11.
In step S13, the supporting portion 12 moves along with the deformation of the battery cell 11, so as to ensure that the inner wall of the battery cell 11 is supported at all times. In practice, this step is performed simultaneously with step S12. The battery cell 11 is flattened to deform, and the supporting part 12 moves downwards along the direction perpendicular to the axis of the battery cell 11 along with the deformation of the battery cell 11, so that the battery cell 11 is kept in contact with the inner wall of the battery cell 11, and the inner wall of the battery cell 11 is supported at all times. In order to ensure that the supporting portion 12 supports the inner wall of the battery cell 11 at any time, the downward movement speed of the supporting portion 12 is matched with the extrusion speed. For example, the downward movement speed of the support 12 is the same as the pressing speed of the battery cell 11. In this step, a baffle plate abutting against the side surface of the electric core 11 can be further added, when the electric core 11 is pressed down and flattened, the electric core 11 is blocked, and the diaphragm of the inner ring of the electric core 11 is prevented from generating an undesired position change in the flattening process. For example, during the process of flattening the battery cell 11, the diaphragm of the inner ring may slide out to the side due to the light weight and the like; at this time, the baffle is abutted against the side face of the battery cell 11, so that the diaphragm can be blocked, and is prevented from sliding out to the side face, thereby ensuring the quality of the battery cell 11 and facilitating the implementation of the rear procedure.
In step S14, the support 12 is pulled out or the battery cell 11 is pulled out.
Through the mode, when the battery cell is flattened, the battery cell is supported in the battery cell, so that the diaphragm on the inner wall of the battery cell can be prevented from wrinkling and collapsing, the quality of the battery cell is ensured, and the following procedures are facilitated.
Referring to fig. 6 and fig. 7, fig. 6 is a schematic front view of an embodiment of a battery cell blanking auxiliary device according to the present application; fig. 7 is a schematic top view of the auxiliary device for blanking the battery cells in fig. 6. In this embodiment, the cell blanking auxiliary device includes a first power mechanism, a second power mechanism, and a supporting portion 26.
The second power mechanism is connected with the first power mechanism and is driven by the first power mechanism to move in the first direction. The support portion 26 is connected to a second power mechanism, and is driven by the second power mechanism to move in a second direction. Wherein the first direction is perpendicular to the second direction. In combination with the above, the first direction may be a direction along an axis of the cell cavity, and the second direction may be a direction perpendicular to the axis of the cell cavity. Alternatively, the first direction is interchangeable with the second direction, i.e., the first direction is a direction perpendicular to the axis of the cell lumen and the second direction is a direction along the axis of the cell lumen. The first direction and the second direction are both bidirectional directions, for example, the first direction is a front-back direction, and the second direction is an up-down direction.
Specifically, the first power mechanism includes a base plate 21, a first power device, a slide rail 23, and a slider 24. The first power means is connected to the base plate 21. The slide rail 23 is provided on the base plate 21 and laid in the first direction. The sliding block 24 is arranged on the sliding rail 23 and is connected with the first power device and the second power mechanism, and the sliding block 24 and the second power mechanism are driven by the first power device to move along the sliding rail 23. The first power device includes a first cylinder fixing base 221 and a first cylinder 222. The first cylinder fixing base 221 is connected with the bottom plate 21, the fixed end of the first cylinder 222 is connected with the first cylinder fixing base 221, and the movable end of the first cylinder 222 is connected with the sliding block 24.
In the present embodiment, the slider 24 is provided with a drive plate 28, and the drive plate 28 is connected with a baffle plate 27, and the baffle plate 27 is provided corresponding to the support portion 26. The baffles 27 are used to abut the sides of the cells to prevent unwanted positional changes of the separator of the inner ring of the cell during the collapsing process. For example, during the cell collapse process, the separator may slide out sideways due to the lighter weight and the like; at this time, the baffle 27 abuts against the side surface of the battery cell, so that the diaphragm can be blocked and prevented from sliding out to the side surface, thereby ensuring the quality of the battery cell and facilitating the execution of the rear process. In other embodiments, the baffle 27 may be connected to other locations, such as directly to the slider 24, to the first power mechanism or to the second power mechanism, and only be capable of being moved in the first direction by the first power mechanism. Preferably, the movement of the shutter 27 and the support 26 in the first direction is a synchronous movement.
Specifically, the second power device includes a second cylinder 251 and a third cylinder 253. The fixed end of the second cylinder 251 is connected to the driving plate 28, the fixed end of the third cylinder 253 is connected to the movable end of the second cylinder 251, and the movable end of the third cylinder 253 is connected to the supporting portion 26. Wherein the movable end of the second cylinder 251 is connected to the fixed end of the third cylinder 253 through a connection plate 252.
Wherein the second cylinder 251 drives the third cylinder 253 to move in the second direction, and the third cylinder 253 drives the support portion 26 to move in the second direction. That is, in the present embodiment, the driving direction of the first cylinder 222 is the first direction, and the driving directions of the second cylinder 251 and the third cylinder 253 are the second direction. The second cylinder 251 is engaged with the third cylinder 253 to control the movement of the support portion 26 in the second direction; the first cylinder 222 controls movement of the support 26 and the shutter 27 in a first direction. The support 26 needs to perform different movements in the second direction, for example, the second direction is the up-down direction, and the speed and path length of the support 26 during the upward movement and the downward movement during operation are likely to be different, so that two cylinders are required to be separately controlled to ensure the accuracy of the movements thereof.
In the present embodiment, a support fixing base 254 is connected to the movable end of the third cylinder 253, and the support portion 26 is connected to the support fixing base 254. In other embodiments, the support portion 26 and the support holder 254 may be integrally formed, i.e., the support holder 254 is also a part of the support portion 26.
The support portion 26 is disposed in the same direction as the baffle plate 27. Wherein, the support portion 26, the third air cylinder 253 and the second air cylinder 251 are respectively provided with two, the two second air cylinders 251 are arranged at two ends of the driving plate 28, the baffle plate 27 is connected to the middle part of the driving plate 28, and the support portion 26 is arranged at two sides of the baffle plate 27. The baffle 27 is located between the two support portions 26. Wherein the baffle 27 is formed with a vertical structure at an end remote from the drive plate 28.
In a specific implementation, the first cylinder 222 can drive the supporting portion 26 to extend into the inner cavity of the battery cell and drive the baffle 27 to abut against the side surface of the battery cell, the second cylinder 251 can drive the supporting portion 26 to move upwards to abut against the inner ring of the battery cell, and the third cylinder 253 can drive the supporting portion 26 to descend synchronously along with the flattening of the battery cell. The cell is crushed by an external member, and the third cylinder 253 drives the support portion 26 to move at the same speed as the external member, so that the support portion 26 always supports the inner wall of the cell. After the battery cell is flattened, the first cylinder 222 can drive the supporting portion 26 to be pulled out of the inner cavity of the battery cell, and the second cylinder 251 and the third cylinder 253 are restored for the next operation. Wherein the movement rates and movement paths of the second cylinder 251 and the third cylinder 253 may not coincide.
Furthermore, in order to reduce the damage of the supporting part to the inner ring of the battery cell, the tail end of the supporting part can be a Mylar film rod which is of a flat rod-shaped structure made of Mylar film. The smooth surface of the Mylar film rod faces upwards to correspond to the inner ring of the battery cell, and the inner ring of the battery cell can be abutted against the maximum area, so that the best supporting effect is achieved. The tail end of the supporting part, namely the part which extends into the inner ring of the battery cell and supports the inner ring of the battery cell. The Mylar film is not easy to deform, can effectively support the inner ring of the battery cell, and has flexibility, so that the inner ring of the battery cell is not easy to damage.
In other embodiments, the cylinder may be replaced by other power devices, such as a motor coupled with a gear and a rack.
