Description

Technical Field

[0001] This application relates to the field of battery cell manufacturing equipment technology, and in particular to a battery cell feeding mechanism and winding equipment. Background Technology

[0002] A battery cell unloading mechanism is a mechanism used to remove battery cells from winding needles and flatten them.

[0003] In the related technologies, the cell feeding mechanism has two problems when flattening the cell. First, the pulling force is difficult to control, which makes it difficult to control the degree of flattening. Second, the way the pulling force is applied is singular and not flexible enough, which makes the flattening effect less than ideal. Utility Model Content

[0004] This application discloses a battery cell feeding mechanism and winding equipment, which makes it easy to control the degree of flattening of the battery cell and achieves a relatively ideal flattening effect.

[0005] To achieve the above objectives, firstly, this application discloses a battery cell feeding mechanism, comprising:

[0006] A first drive module, comprising a first drive component and a second drive component;

[0007] A clamping module, comprising a first clamping component and a second clamping component, wherein the first clamping component is connected to the first driving component and the second clamping component is connected to the second driving component.

[0008] Since the first clamping component is connected to the first driving component and the second clamping component is connected to the second driving component, the first driving component is used to drive the first clamping component to move in a direction closer to or farther from the second clamping component, and / or the second driving component is used to drive the second clamping component to move in a direction closer to or farther from the first clamping component. Therefore, the first clamping component has a separate first driving component specifically used to drive the first clamping component to move closer to or farther from the second clamping component, and the second clamping component has a separate second driving component specifically used to drive the second clamping component to move closer to or farther from the first clamping component.

[0009] With this configuration, when it is necessary to flatten the battery cell, the first drive component can independently drive the first clamping component to move closer to or further away from the second clamping component, and the second drive component can also independently drive the second clamping component to move closer to or further away from the first clamping component. During the driving operation of the first drive component and the second drive component, it is not necessary to worry about whether the first clamping component and the second clamping component move away from each other at the same time. It is only necessary to ensure that the distance between the first clamping component and the second clamping component increases to achieve the purpose of flattening the battery cell.

[0010] Meanwhile, on the one hand, since the pulling force of the first clamping component and the second clamping component when flattening the battery cell comes from the first driving component and the second driving component respectively, the application of the pulling force is more diverse and flexible, resulting in a more ideal flattening effect. On the other hand, since the pulling force of the first clamping component comes from the first driving component and the pulling force of the second clamping component comes from the second driving component, the pulling forces of the first clamping component and the second clamping component are independent of each other and will not affect each other. Moreover, the magnitude of the pulling force is easier to control. Therefore, the degree of flattening of the battery cell can be better controlled.

[0011] In addition, since the first driving component can independently drive the first clamping component to move closer to or further away from the second clamping component, and the second driving component can also independently drive the second clamping component to move closer to or further away from the first clamping component, by making the movement direction of the first clamping component driven by the first driving component the same as the movement direction of the second clamping component driven by the second driving component, it can also play the role of transporting the battery cell. That is, by flexibly selecting the driving mode of the first driving component and the second driving component, the first clamping component and the second clamping component not only have the function of flattening the battery cell, but also the function of transporting the battery cell. It is multi-functional and has a clever structural design, making the battery cell feeding mechanism more versatile.

[0029] Optionally, the first clamping pin is fixedly disposed on the first moving member, and the second clamping pin is slidably disposed on the first moving member in a direction close to or away from the first clamping pin. The first clamping pin driving member is connected to the second clamping pin, and the sliding direction of the second clamping pin is the same as the movement direction of the first moving member.

[0030] Optionally, the cell feeding mechanism further includes:

[0031] The second drive module is disposed on the second drive module.

[0032] Optionally, the cell feeding mechanism further includes:

[0033] A third drive module is provided, wherein the second drive module is disposed on the third drive module, the third drive module is used to drive the second drive module to move along a second direction, and the second drive module is used to drive the first drive module to move along a first direction, wherein the second direction and the first direction are different.

[0034] Optionally, the direction in which the first driving component drives the first clamping component to move and the second direction are both parallel to the same horizontal plane, the first direction is a vertical direction, and each of the three directions is perpendicular to the other.

[0037] Optionally, the winding device further includes:

[0038] A flattening mechanism is located on one side of the cell feeding mechanism along the direction in which the first driving component drives the first clamping component to move.

[0039] Optionally, the first driving component and the second driving component are further configured to drive the first clamping component and the second clamping component to move, so as to transport the battery cell to the flattening mechanism.

[0040] Compared with the prior art, the beneficial effects of this application are as follows:

[0041] Since the first clamping component is connected to the first driving component and the second clamping component is connected to the second driving component, the first driving component can drive the first clamping component to move in a direction closer to or farther from the second clamping component, and / or the second driving component can drive the second clamping component to move in a direction closer to or farther from the first clamping component. Thus, the first clamping component has a separate first driving component specifically designed to drive the first clamping component to move closer to or farther from the second clamping component, and the second clamping component has a separate second driving component specifically designed to drive the second clamping component to move closer to or farther from the first clamping component.

[0042] With this configuration, when it is necessary to flatten the battery cell, the first drive component can independently drive the first clamping component to move closer to or further away from the second clamping component, and the second drive component can also independently drive the second clamping component to move closer to or further away from the first clamping component. During the driving operation of the first drive component and the second drive component, it is not necessary to worry about whether the first clamping component and the second clamping component move away from each other at the same time. It is only necessary to ensure that the distance between the first clamping component and the second clamping component increases to achieve the purpose of flattening the battery cell.

[0043] Meanwhile, on the one hand, since the pulling force of the first clamping component and the second clamping component when flattening the battery cell comes from the first driving component and the second driving component respectively, the application of the pulling force is more diverse and flexible, resulting in a more ideal flattening effect. On the other hand, since the pulling force of the first clamping component comes from the first driving component and the pulling force of the second clamping component comes from the second driving component, the pulling forces of the first clamping component and the second clamping component are independent of each other and will not affect each other. Moreover, the magnitude of the pulling force is easier to control. Therefore, the degree of flattening of the battery cell can be better controlled.

[0044] In addition, since the first driving component can independently drive the first clamping component to move closer to or further away from the second clamping component, and the second driving component can also independently drive the second clamping component to move closer to or further away from the first clamping component, by making the movement direction of the first clamping component driven by the first driving component the same as the movement direction of the second clamping component driven by the second driving component, it can also play the role of transporting the battery cell. That is, by flexibly selecting the driving mode of the first driving component and the second driving component, the first clamping component and the second clamping component not only have the function of flattening the battery cell, but also the function of transporting the battery cell. It is multi-functional and has a clever structural design, making the battery cell feeding mechanism more versatile. Attached Figure Description

[0066] Before explaining the technical solution of this application, the background technology of this application shall be explained first.

[0067] A battery cell unloading mechanism is a mechanism used to remove battery cells from winding needles and flatten them.

[0068] In related technologies, the cell cutting mechanism suffers from two main problems when flattening the cell: firstly, the pulling force is difficult to control, resulting in inconsistent flattening degree; secondly, the application of the pulling force is simplistic and inflexible, leading to unsatisfactory flattening results. Therefore, this application provides a novel cell cutting mechanism to address these issues.

[0069] The technical solution of this application will be described below with reference to specific embodiments and accompanying drawings.

[0070] Figure 1 This is a schematic diagram of the structure of a battery cell feeding mechanism 100 provided in one embodiment of this application. Figure 2 yes Figure 1 A schematic diagram of the cell feeding mechanism 100 from another perspective. Figure 3 yes Figure 2 A simplified structural diagram of the cell feeding mechanism 100 clamping cell D from a positive X-axis viewpoint. Figure 4 yes Figure 3 A schematic diagram of the structure of cell D before it is flattened. Figure 5 yes Figure 3 A schematic diagram of the structure of cell D after it has been flattened.

[0071] See Figure 1 , Figure 2 and Figure 3 The cell feeding mechanism 100 includes a first drive module 1 and a clamping module 2. The first drive module 1 includes a first drive component 11 and a second drive component 12. The clamping module 2 includes a first clamping component 21 and a second clamping component 22. The first clamping component 21 is connected to the first drive component 11, and the second clamping component 22 is connected to the second drive component 12. The first clamping component 21 and the second clamping component 22 are used to clamp the cell D respectively.

[0072] The first driving component 11 is used to drive the first clamping component 21 in a direction that is closer to or farther from the second clamping component 22. Figure 2 The second drive assembly 12 is used to drive the second clamping assembly 22 in a direction closer to or farther from the first clamping assembly 21 (in the Y-axis direction) and / or, the second drive assembly 12 is used to drive the second clamping assembly 22 in a direction closer to or farther from the first clamping assembly 21 (in the Y-axis direction) Figure 2 (Movement in the Y-axis direction).

[0073] In this embodiment, when it is necessary to flatten the battery cell D, since the first clamping component 21 is connected to the first driving component 11 and the second clamping component 22 is connected to the second driving component 12, and the first clamping component 21 and the second clamping component 22 are used to clamp the battery cell D respectively, therefore, when the first clamping component 21 and the second clamping component 22 respectively clamp the battery cell D ( Figure 3 In the middle state), when the first driving component 11 drives the first clamping component 21 in a direction away from the second clamping component 22 ( Figure 3 The second drive assembly 12 drives the second clamping assembly 22 in a direction away from the first clamping assembly 21 (positive Y-axis direction) to move, and / or the ... to move (positive Y-axis direction) to move, and / Figure 3 When moving in the negative direction of the Y-axis, the distance between the first clamping assembly 21 and the second clamping assembly 22 can be increased, causing the battery cell D to change from a circular shape ( Figure 4 (in the middle state) becomes flat ( Figure 5 (in the middle state), thus achieving the purpose of flattening the cell D.

[0074] Wherein, since the first clamping component 21 is disposed on the first driving component 11 and the second clamping component 22 is disposed on the second driving component 12, the first driving component 11 is used to drive the first clamping component 21 in a direction that is closer to or farther from the second clamping component 22. Figure 2 The second drive assembly 12 is used to drive the second clamping assembly 22 in a direction closer to or farther from the first clamping assembly 21 (in the Y-axis direction) and / or, the second drive assembly 12 is used to drive the second clamping assembly 22 in a direction closer to or farther from the first clamping assembly 21 (in the Y-axis direction) Figure 2(In the Y-axis direction) movement. Therefore, the first clamping assembly 21 has a separate first drive assembly 11 specifically for driving the first clamping assembly 21 to move toward or away from the second clamping assembly 22, and the second clamping assembly 22 has a separate second drive assembly 12 specifically for driving the second clamping assembly 22 to move toward or away from the first clamping assembly 21.

[0075] With this configuration, the movement of the first clamping component 21 depends entirely on the driving of the first driving component 11, and is not affected by the second driving component 12 and the second clamping component 22. Similarly, the movement of the second clamping component 22 also depends entirely on the driving of the second driving component 12, and is not affected by the first clamping component 21 and the first driving component 11.

[0076] In this way, when it is necessary to flatten the battery cell D, the first driving component 11 can independently drive the first clamping component 21 to move closer to or further away from the second clamping component 22, and the second driving component 12 can also independently drive the second clamping component 22 to move closer to or further away from the first clamping component 21. During the driving operation of the first driving component 11 and the second driving component 12, it is not necessary to care whether the first clamping component 21 and the second clamping component 22 move away from each other at the same time. It is only necessary to ensure that the distance between the first clamping component 21 and the second clamping component 22 increases to achieve the purpose of flattening the battery cell D.

[0077] Meanwhile, on the one hand, since the pulling force of the first clamping component 21 and the second clamping component 22 when flattening the battery cell D comes from the first driving component 11 and the second driving component 12 respectively, the application of the pulling force is more diverse and flexible, resulting in a more ideal flattening effect. On the other hand, since the pulling force of the first clamping component 21 comes from the first driving component 11 and the pulling force of the second clamping component 22 comes from the second driving component 12, the pulling forces of the first clamping component 21 and the second clamping component 22 are independent of each other and will not affect each other. Moreover, the magnitude of the pulling force is easier to control. Therefore, the degree of flattening of the battery cell D can be better controlled.

[0078] In addition, since the first driving component 11 can independently drive the first clamping component 21 to move closer to or further away from the second clamping component 22, and the second driving component 12 can also independently drive the second clamping component 22 to move closer to or further away from the first clamping component 21, by making the movement direction of the first driving component 11 driving the first clamping component 21 the same as the movement direction of the second driving component 12 driving the second clamping component 22, it can also play the role of transporting the battery cell D. That is, by flexibly selecting the driving mode of the first driving component 11 and the second driving component 12, the first clamping component 21 and the second clamping component 22 not only have the function of flattening the battery cell D, but also have the function of transporting the battery cell D. It is multi-functional and has a clever structural design, making the battery cell feeding mechanism 100 more versatile.

[0079] In some embodiments, see Figure 2 The direction of movement of the first clamping component 21 ( Figure 2 (in the Y-axis direction) and the movement direction of the second clamping assembly 22 ( Figure 2 Parallel to the Y-axis direction.

[0080] When the movement direction of the first clamping component 21 is parallel to the movement direction of the second clamping component 22, when the battery cell D is flattened by moving the first clamping component 21 and the second clamping component 22 away from each other, the movement speed of the first clamping component 21 and the movement speed of the second clamping component 22 can be directly added together, making the first clamping component 21 and the second clamping component 22 move away from each other faster, thereby making the battery cell feeding mechanism 100 more efficient at flattening the battery cell D.

[0081] The fact that the movement direction of the first clamping component 21 is parallel to the movement direction of the second clamping component 22 is only one possible movement direction given in this embodiment. In other possible embodiments, the movement direction of the first clamping component 21 and the movement direction of the second clamping component 22 may not be parallel. For example, the movement direction of the first clamping component 21 and the movement direction of the second clamping component 22 may also have an angle. This embodiment does not limit this.

[0082] In some embodiments, see Figure 2 The first drive module 1 also includes a base 13, and the first drive assembly 11 includes a first lead screw assembly 111, which is disposed on the base 13. A first clamping assembly 21 is disposed on the first lead screw assembly 111, and the first lead screw assembly 111 is used to drive the first clamping assembly 21 in a direction closer to or further away from the second clamping assembly 22. Figure 2 (Movement in the Y-axis direction).

[0083] The second drive assembly 12 includes a second lead screw assembly 121, which is disposed on the base 13. The second clamping assembly 22 is disposed on the second lead screw assembly 121. The second lead screw assembly 121 is used to drive the second clamping assembly 22 to move in a direction close to or away from the first clamping assembly 21.

[0084] Since both the first lead screw assembly 111 and the second lead screw assembly 121 are located on the base 13, that is, both the first drive assembly 11 and the second drive assembly 12 are located on the base 13, there is no need to set separate bases for each of the first lead screw assembly 111 and the second lead screw assembly 121. Therefore, the number of parts in the first drive module 1 can be reduced, and the cost of the first drive module 1 can be reduced.

[0085] Additionally, since the first lead screw assembly 111 is used to drive the first clamping assembly 21 in a direction closer to or further away from the second clamping assembly 22 ( Figure 2 The first clamping assembly 22 moves in the direction of the Y-axis. The second lead screw assembly 121 is used to drive the second clamping assembly 22 to move in the direction of approaching or moving away from the first clamping assembly 21. That is, the movement of the first clamping assembly 21 and the movement of the second clamping assembly 22 are both driven by the lead screw structure. Since the lead screw structure is simple and the technology is mature, the reliability of the operation of the first drive module 1 can be guaranteed while simplifying the structure of the first drive module 1.

[0086] Specifically, the first lead screw assembly 111 described above can be implemented in various ways. In one possible implementation, see [link to relevant documentation]. Figure 2 The first lead screw assembly 111 includes a first lead screw 1111 and a first drive member 1112. The first lead screw 1111 is rotatably disposed on the base 13. The first drive member 1112 is disposed on the base 13 and connected to the first lead screw 1111. The first drive member 1112 is used to drive the first lead screw 1111 to rotate. The first clamping assembly 21 is disposed on the first lead screw 1111. When the first lead screw 1111 rotates, it can drive the first clamping assembly 21 to reciprocate along the extension direction of the first lead screw 1111.

[0087] Since the first lead screw 1111 is rotatably mounted on the base 13, and the first driving member 1112 is mounted on the base 13 and connected to the first lead screw 1111, the first driving member 1112 can drive the first lead screw 1111 to rotate. When the first lead screw 1111 rotates, it can drive the first clamping assembly 21 along the extension direction of the first lead screw 1111. Figure 2 The reciprocating motion (in the Y-axis direction) can achieve the purpose of moving the first clamping component 21 towards or away from the second clamping component 22, thereby flattening the battery cell D.

[0088] Specifically, the first lead screw 1111 drives the first clamping assembly 21 along the extension direction of the first lead screw 1111. Figure 2 The reciprocating motion (in the Y-axis direction) can be as follows: a slide table can be threadedly connected to the first lead screw 1111. The slide table is slidably disposed on the base 13 along the extension direction of the first lead screw 1111. The first clamping assembly 21 is disposed on the slide table. In this way, when the first lead screw 1111 rotates, the first lead screw 1111 can drive the slide table to slide along the extension direction of the first lead screw 1111, thereby driving the first clamping assembly 21 to move along the extension direction of the first lead screw 1111. Figure 2 The purpose of the reciprocating motion (in the Y-axis direction).

[0089] Since the rotation of the first lead screw 1111 is driven independently by the first drive member 1112, the movement of the first clamping assembly 21 can be made more independent and will not be affected by other structures.

[0090] The first driving component 1112 mentioned above can be a stepper motor or a servo motor, as long as it can drive the first lead screw 1111 to rotate. This embodiment does not limit the first driving component 1112.

[0091] The implementation of the second lead screw assembly 121 can be similar to that of the first lead screw assembly 111. Specifically, see [link to relevant documentation]. Figure 2 The second lead screw assembly 121 includes a second lead screw 1211 and a second drive member 1212. The second lead screw 1211 is rotatably disposed on the base 13. The second drive member 1212 is disposed on the base 13 and connected to the second lead screw 1211. The second drive member 1212 is used to drive the second lead screw 1211 to rotate. The second clamping assembly 22 is disposed on the second lead screw 1211. When the second lead screw 1211 rotates, it can drive the second clamping assembly 22 to reciprocate along the extension direction of the second lead screw 1211.

[0092] The structure of the second lead screw 1211 can be the same as or similar to that of the first lead screw 1111. For details, please refer to the description of the first lead screw 1111 in the above embodiments; this will not be repeated here. Similarly, the structure of the second driving member 1212 can be the same as or similar to that of the first driving member 1112. For details, please refer to the description of the first driving member 1112 in the above embodiments; this will not be repeated here either.

[0093] In some embodiments, see Figure 2 The extension direction of the first lead screw 1111 is parallel to the extension direction of the second lead screw 1211, and the first lead screw 1111 and the second lead screw 1211 are arranged side by side.

[0094] By making the extension direction of the first lead screw 1111 parallel to the extension direction of the second lead screw 1211, when the battery cell D is flattened by moving the first clamping component 21 and the second clamping component 22 away from each other, the movement speed of the first clamping component 21 and the movement speed of the second clamping component 22 can be directly added together, making the speed at which the first clamping component 21 and the second clamping component 22 move away from each other faster, thereby making the battery cell feeding mechanism 100 more efficient at flattening the battery cell D.

[0095] By arranging the first lead screw 1111 and the second lead screw 1211 side by side, the structural layout of the first lead screw 1111 and the second lead screw 1211 on the base 13 can be made more compact, thereby making the entire first drive module 1 smaller in size.

[0096] In some embodiments, see Figure 2 The first drive element 1112 includes a motor; and / or, the second drive element 1212 includes a motor.

[0097] Because the motor has a simple structure and mature technology, the cost of the first drive component 1112 and the second drive component 1212 can be reduced while ensuring reliable operation of the first drive component 1112 and the second drive component 1212.

[0098] The motor mentioned above can be a stepper motor or a servo motor, etc., and this embodiment does not limit it.

[0099] In some embodiments, see Figure 2 , Figure 4 and Figure 6 , Figure 6 yes Figure 2 The schematic diagram of the cell feeding mechanism from another perspective shows that the first clamping assembly 21 includes a first moving member 211, a first clamping pin 212, a second clamping pin 213, and a first clamping pin driving member 214. The first moving member 211 is disposed on the first driving assembly 11, which drives the first moving member 211 to move in a direction closer to or away from the second clamping assembly 22. The first clamping pin 212 is disposed on the first moving member 211, and the second clamping pin 213 is disposed on the first moving member 211 and opposite to the first clamping pin 212. The first clamping pin driving member 214 is disposed on the first moving member 211 and is connected to the first clamping pin 212 and / or the second clamping pin 213.

[0100] Since the first clamping pin 212 is disposed on the first moving member 211, the second clamping pin 213 is disposed on the first moving member 211 and opposite to the first clamping pin 212, and the first clamping pin driving member 214 is disposed on the first moving member 211 and connected to the first clamping pin 212 and / or the second clamping pin 213, therefore, when it is necessary to clamp the battery cell D by the first clamping assembly 21, firstly, the first clamping pin 212 and / or the second clamping pin 213 can be driven by the first clamping pin driving member 214 in a direction away from the other ( Figure 2 The first clamping pin 212 moves along the Y-axis, creating a gap between the second clamping pin 213 and the first clamping pin 212. Then, the battery cell D can be inserted into the gap. Finally, the first clamping pin drive 214 can drive either the second clamping pin 213 or the first clamping pin 212 towards the other. Figure 2 The cell D moves along the Y-axis, so that it is clamped between the second clamping pin 213 and the first clamping pin 212, thus achieving the purpose of clamping the cell D by the second clamping pin 213 and the first clamping pin 212.

[0101] As can be seen, by setting the first clamping pin 212 on the first moving member 211, setting the second clamping pin 213 on the first moving member 211 and opposite to the first clamping pin 212, setting the first clamping pin driving member 214 on the first moving member 211, and connecting the first clamping pin driving member 214 with the first clamping pin 212 and / or the second clamping pin 213, the battery cell D can be tightly clamped between the second clamping pin 213 and the first clamping pin 212, thereby preventing the battery cell D from abnormally detaching from the first clamping assembly 21.

[0102] In some embodiments, see Figure 2 and Figure 6 The first clamping pin 212 is fixedly disposed on the first moving member 211, and the second clamping pin 213 is slidably disposed on the first moving member 211 in a direction close to or away from the first clamping pin 212. The first clamping pin driving member 214 is connected to the second clamping pin 213 and is used to drive the second clamping pin 213 to slide in a direction close to or away from the first clamping pin 212.

[0103] Since the first clamping pin 212 is fixedly mounted on the first moving member 211, and the second clamping pin 213 is slidably mounted on the first moving member 211 in a direction approaching or away from the first clamping pin 212, the purpose of clamping the battery cell D can be achieved simply by driving the second clamping pin 213 to slide in a direction approaching or away from the first clamping pin 212 through the first clamping pin driving member 214, while keeping the first clamping pin 212 stationary. In this way, it is unnecessary to make the first clamping pin 212 slidably mounted on the first moving member 211, nor is it necessary to provide a driving member to drive the first clamping pin 212 to slide in a direction approaching or away from the second clamping pin 213. Therefore, the structure of the first clamping assembly 21 can be simplified and its cost reduced while ensuring that the battery cell D can be clamped.

[0104] There are multiple ways to implement the second clamping pin 213 being slidably disposed on the first moving member 211 in a direction close to or away from the first clamping pin 212. In one possible implementation, the second clamping pin 213 can be slidably disposed on the first moving member 211 through a slide rail assembly. Of course, the second clamping pin 213 can also be slidably disposed on the first moving member 211 in other ways. This embodiment does not limit this.

[0105] The first clamping needle drive component 214 mentioned above can be a cylinder or an electric cylinder, etc., and this embodiment does not limit it.

[0106] It should be noted that the structure of the second clamping component 22 can be the same as or similar to that of the first clamping component 21, and can bring the same or similar beneficial effects. For details, please refer to the description of the first clamping component 21 in the above embodiments. This embodiment will not repeat the description here.

[0107] In some embodiments, see Figure 2 The sliding direction of the second clamping pin 213 ( Figure 2 (in the Y-axis direction) and the movement direction of the first moving member 211 ( Figure 2 (Same as the Y-axis direction).

[0108] By making the sliding direction of the second clamp 213 ( Figure 2 (in the Y-axis direction) and the movement direction of the first moving member 211 ( Figure 2The sliding direction of the second clamping pin 213 is the same as that of the first moving member 211 in the Y-axis direction. On the one hand, this makes the sliding direction of the second clamping pin 213 more aligned with the movement direction of the first moving member 211, which is convenient for structural design. On the other hand, when the battery cell D is clamped by the first clamping pin 212 and the second clamping pin 213, when the first moving member 211 moves the battery cell D, the first clamping pin 212 and the second clamping pin 213 can be located on both sides of the movement direction of the first moving member 211. With this arrangement, the battery cell D is less likely to detach from the first clamping pin 212 and the second clamping pin 213, thereby reducing the possibility of the battery cell D detaching from the first clamping pin 212 and the second clamping pin 213 during the movement of the battery cell D by the first moving member 211.

[0109] Of course, in other embodiments, the sliding direction of the second clamping pin 213 may be different from the movement direction of the first moving member 211, and this embodiment does not limit this.

[0110] In some embodiments, see Figure 2 and Figure 4 The cell feeding mechanism 100 also includes a second drive module 3, with a first drive module 1 disposed on the second drive module 3. The second drive module 3 is used to drive the first drive module 1 along a first direction ( Figure 2 The movement is in the Z-axis direction, and the first direction is different from the direction in which the first driving component 11 drives the first clamping component 21 to move.

[0111] Since the first drive module 1 is located on the second drive module 3, and since the second drive module 3 is used to drive the first drive module 1 to move along the first direction, which is different from the movement direction of the first clamping component 21, after the first clamping component 21 and the second clamping component 22 clamp the battery cell D, under the action of the second drive module 3, the battery cell D can also be driven to move up and down along the first direction, which is different from the movement direction of the first clamping component 21, thereby achieving the purpose of transporting the battery cell D along the first direction, making the battery cell unloading mechanism 100 more capable of transporting the battery cell D.

[0112] The second drive module 3 mentioned above can be a linear module or a lead screw and nut assembly, etc. This embodiment does not limit the specific structure of the second drive module 3.

[0113] In some embodiments, see Figure 2 and Figure 3 The cell feeding mechanism 100 also includes a third drive module 4, with the second drive module 3 disposed on the third drive module 4. The third drive module 4 is used to drive the second drive module 3 along a second direction ( Figure 2 The first clamping component 21 and the second clamping component 22 move in the X-axis direction to drive them to be inserted into the battery cell D. The second direction is different from the direction in which the first driving component 11 drives the first clamping component 21 to move and the first direction.

[0114] Since the second drive module 3 is disposed within the third drive module 4, the third drive module 4 can drive the second drive module 3 along the second direction ( Figure 2 The second drive module 3 moves along the second direction (X-axis direction) when the second drive module 3 moves along the second direction (X-axis direction). Figure 2 When moving along the X-axis direction, since the first drive module 1 is located on top of the second drive module 3, when the second drive module 3 moves along the second direction (X-axis direction), Figure 2 When moving along the X-axis, it can drive the first drive module 1 along the second direction. Figure 2 (Movement in the X-axis direction).

[0115] When the first drive module 1 moves along the second direction ( Figure 2 When moving along the X-axis, since the first clamping component 21 and the second clamping component 22 are disposed in the first drive module 1, they can be driven to move synchronously along the second direction (X-axis direction). Figure 2 The movement (in the X-axis direction) can achieve the purpose of synchronously inserting the first clamping component 21 and the second clamping component 22 into the battery cell D.

[0116] It can be seen that by positioning the second drive module 3 above the third drive module 4, when the third drive module 4 moves along the second direction ( Figure 2 When the mechanism moves in the X-axis direction, it can drive the first clamping component 21 and the second clamping component 22 to be inserted into the battery cell D simultaneously. The first clamping component 21 and the second clamping component 22 can share the same third drive module 4 to drive the first clamping component 21 and the second clamping component 22 to be inserted into the battery cell D simultaneously. There is no need to set independent drives for the first clamping component 21 and the second clamping component 22. Therefore, the structure of the battery cell unloading mechanism 100 can be simplified and the cost of the battery cell unloading mechanism 100 can be reduced.

[0117] The structure of the third drive module 4 can be the same as or similar to that of the second drive module 3. For details, please refer to the description of the second drive module 3 in the above embodiments. This embodiment will not repeat the description here.

[0118] In some embodiments, see Figure 2 Second direction ( Figure 2 (in the X-axis direction) and the direction in which the first drive assembly 11 drives the first clamping assembly 21 to move ... Figure 2 The Y-axis direction is parallel to the same horizontal plane, and the first direction ( Figure 2 The Z-axis direction is vertical, and all three directions are perpendicular to each other.

[0119] By ensuring that the second direction and the direction in which the first driving component 11 drives the first clamping component 21 to move are both parallel to the same horizontal plane, and the first direction is vertical, and by ensuring that the second direction, the direction of movement of the first clamping component 21, and the first direction are all perpendicular to each other, with the cooperation of the third driving module 4, the second driving module 3, and the first driving module 1, the first clamping component 21 and the second clamping component 22 can be moved to any position in three-dimensional space. With this configuration, on the one hand, the battery cell feeding mechanism 100 can better flatten the battery cell D, and on the other hand, it can more flexibly transport the battery cell D to the destination position.

[0120] Figure 7 This is a schematic diagram (partial structure) of a winding device 200 provided in an embodiment of this application. See also... Figure 2 and Figure 7 The winding equipment 200 includes a cell feeding mechanism 100.

[0121] The structure of the cell feeding mechanism 100 can be the same as that of any of the cell feeding mechanisms 100 described in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments. This embodiment will not repeat the description here.

[0122] In this embodiment, since the degree to which the battery cell flattening mechanism 100 flattens the battery cell is easy to control and the flattening effect is also relatively ideal, when the winding equipment 200 includes the battery cell flattening mechanism 100, the quality of the battery cell produced by the winding equipment 200 can be better.

[0123] In some embodiments, see Figure 7 The winding device 200 also includes a flattening mechanism 5, which moves along the direction in which the first driving assembly 11 drives the first clamping assembly 21. Figure 7 The middle Y-axis direction) is located on one side of the cell feeding mechanism 100.

[0124] By positioning the flattening mechanism 5 on one side of the cell feeding mechanism 100 along the direction in which the first driving assembly 11 drives the first clamping assembly 21, the flattening mechanism 5 can occupy little or no space directly below the first driving module 1. On the one hand, this can reduce the possibility of interference between the flattening mechanism 5 and other structures of the cell feeding mechanism 100 to a certain extent. On the other hand, it can also avoid interference from other structures of the cell feeding mechanism 100 when maintaining the flattening mechanism 5, making maintenance of the flattening mechanism 5 more convenient.

[0125] In some embodiments, see Figure 2 and Figure 7The first driving component 11 and the second driving component 12 are also used to drive the first clamping component 21 and the second clamping component 22 to move, so as to transport the battery cell D to the flattening mechanism 5, which is used to flatten the battery cell D at the flattening mechanism 5.

[0126] In this embodiment, when the first driving component 11 and the second driving component 12 drive the first clamping component 21 and the second clamping component 22 to move in the same direction, the battery cell D can be transported to the flattening mechanism 5 for flattening. In this way, the flattening mechanism 5 does not need to move itself; instead, it is fixed in place and awaits the first driving component 11 and the second driving component 12 to drive the first clamping component 21 and the second clamping component 22 to actively transport the battery cell D to the flattening mechanism 5. This eliminates the need for a driving mechanism to drive the flattening mechanism 5 to the battery cell D, thereby simplifying the structure of the winding equipment 200 and reducing its cost. Furthermore, for the bulky flattening mechanism 5, fixing it in place avoids the structural instability and difficulties associated with driving its movement compared to driving it to move.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
