[0046] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0047] In the process of winding the material belt, when one battery cell is wound, the material belt needs to be cut off, and the tail of the material belt after cutting often cannot fall into the downstream position of the two deviation correction rollers in time, thereby affecting the continuity of the battery cell winding, not only increasing the waiting time in the winding process, but also reducing the overall winding efficiency.

[0048] The present application provides a deviation correction device, the second roller of the deviation correction device can be close to or away from the first roller, so that the distance between the two rollers can be flexibly adjusted, and the material belt after cutting upstream can fall from the opening between the two rollers to the downstream of the two rollers, the downstream of the two rollers can be the area beyond the two rollers in the material belt conveying direction, to ensure the efficiency of the material belt transmission.

[0049] With reference to Figures 1 to 3 The deviation correction device provided by the present application comprises:

[0050] The mounting seat 1 is provided with a first guide 11, and the first guide 11 is arranged in a first direction;

[0051] The first movable assembly 2 comprises a deviation correction plate 22 and a first roller 21, and the first roller 21 is connected to the deviation correction plate 22;

[0052] The second movable assembly 3, as shown in Figure 7 and Figure 8 The second movable assembly 3 comprises a moving plate 33, a second roller 31 and a movable piece 332, the second roller 31 is movably connected to the moving plate 33 in the first direction through the movable piece 332, the moving plate 33 is movably arranged on the mounting base 1 in the second direction, so that the second roller 31 can be close to or away from the first roller 21, and the second direction intersects the first direction.

[0053] The deviation rectifying plate 22 is slidably connected to the first guide 11, and the movable piece 332 is connected to the deviation rectifying plate 22, so that the first roller 21 and the second roller 31 can move in the first direction.

[0054] In this embodiment, the second roller 31 can clamp the material tape 100 when it is close to the first roller 21, and the deviation rectifying plate 22 drives the first roller 21 and the second roller 31 to move synchronously, so as to rectify the material tape 100 clamped between the first roller 21 and the second roller 31, while avoiding the movement of the moving plate 33 in the first direction.

[0055] In this embodiment, the first guide 11 can be a guide rod or a slide rail, the material tape 100 can be a roll material such as a pole piece or a film material, and the first direction can be parallel to the width direction of the material tape 100, that is, the deviation rectifying direction of the material tape 100.

[0056] As shown in Figure 1 and Figure 3 When the material tape 100 is clamped between the first roller 21 and the second roller 31, the deviation rectifying plate 22 can drive the first roller 21 to move together in the width direction of the material tape 100 (a direction perpendicular to the paper surface in the figure) when it slides along the first guide 11. Through the cooperation of the first movable assembly 2 and the second movable assembly 3, the material tape clamped can be accurately rectified through the movement of the first roller 21 and the second roller 31, so as to ensure that the material tape always keeps in the correct position during the conveying process, which helps to improve the overall efficiency of the cell winding and the product quality. Figure 1 Meanwhile, when the material tape 100 is clamped by the first roller 21 and the second roller 31, at least one of the first roller 21 and the second roller 31 rotates, such as the first roller 21 as the driving roller rotates, the second roller 31 rotates as the driven roller, or the second roller 31 as the driving roller rotates, the first roller 21 rotates as the driven roller, or both the first roller 21 and the second roller 31 rotate as the driving rollers, so that the material tape can be conveyed downstream while being rectified, thereby ensuring the continuity and stability of the material tape transmission and winding.

[0057]

[0058] ​In the embodiment, the second direction can be the connecting direction between the second roller 31 and the first roller 21, that is, when the moving plate 33 moves in the second direction, the second roller 31 can be driven to move close to or away from the first roller 21. The second roller 31 moves close to or away from the first roller 21, so that the distance between the two rollers can be flexibly adjusted, for example, the distance between the second roller 31 and the first roller 21 is adjusted to be larger, which can facilitate the falling of the material belt 100 after being cut upstream from the opening between the two rollers to the downstream of the two rollers, see Figure 1 , which ensures the efficiency of the material belt 100 transmission.

[0059] In an embodiment, see Figure 1 , the battery cell includes a first pole piece, a second pole piece, and two layers of separators when being wound, the separators are arranged between the first pole piece and the second pole piece, the first pole piece can be one of a negative pole piece and a positive pole piece, and the second pole piece can be the other one of the negative pole piece and the positive pole piece, and the first pole piece of the outer ring can be the above-mentioned pole piece, and the length of the tail of the pole piece is longer than the length of the tail of the second pole piece.

[0060] At the same time, the clamping of the first roller 21 and the second roller 31 on the pole piece can also realize the deviation correction of the pole piece, and improve the stability and yield of the pole piece winding.

[0061] In addition, the second movable assembly 3 provided in the embodiment of the application is movably arranged, so that the second roller 31 can move close to or away from the first roller 21, so that the deviation correction device can adapt to material belts of different widths and thicknesses, and the flexibility and adaptability of the deviation correction device are enhanced.

[0062] In the embodiment of the application, the second direction intersects the first direction, for example, the angle between the second direction and the first direction is 60°, 90°, 120°, or 150°, that is, the direction in which the second roller 31 moves close to or away from the first roller 21 does not interfere with the direction in which the first roller 21 and the second roller 31 jointly correct the deviation, which facilitates the adjustment of the distance between the second roller 31 and the first roller 21, and facilitates the deviation correction of the material belt 100 while the distance between the second roller 31 and the first roller 21 is increased.

[0063] In some embodiments, see Figure 7 and Figure 8 , the movable part 332 is a spline shaft, the moving plate 33 is provided with a spline sleeve, the second roller 31 is connected to the spline shaft, and the spline shaft is in sliding fit with the spline sleeve in the first direction.

[0064] In the above-mentioned embodiment, the second roller 31 can be connected to the spline shaft through a bearing, so that the second roller 31 is relatively fixed with the spline shaft in the axial direction, and at the same time, the second roller 31 can rotate relative to the spline shaft.

[0065] In the above embodiment, the cooperation between the spline shaft and the spline sleeve can ensure the position accuracy and transmission efficiency of the second roller 31 during movement. The relative sliding between the connecting members is reduced, the transmission efficiency of the entire deviation correcting device is improved, and the movement of the moving plate 33 in the first direction is avoided.

[0066] In other embodiments, the movable member 332 can be a guide rod, and the moving plate 33 is provided with a linear bearing. The second roller 31 is fixed to the guide rod, and the guide rod is movably connected to the linear bearing in the first direction. In this way, the deviation of the material belt 100 can be corrected, and the movement of the moving plate 33 in the first direction is avoided.

[0067] In some embodiments, referring to Figure 3 , the first roller 21 is rotationally connected to the deviation correcting plate 22, and the second roller 31 is rotatable relative to the spline shaft. In this way, the material belt 100 clamped between the first roller 21 and the second roller 31 can be conveyed downstream.

[0068] In this embodiment, the first movable assembly 2 can include a first roller driving member 25 arranged on the mounting seat 1. The first roller driving member 25 can drive the first roller 21 to rotate. The contact between the first roller 21 and the material belt 100 is rolling friction, which has smaller resistance and higher efficiency than sliding friction. This helps to reduce friction loss during deviation correction and improves the response speed and accuracy of deviation correction.

[0069] In this embodiment, when the second roller 31 approaches the first roller 21 and clamps the material belt 100 between the first roller 21 and the second roller 31, the first roller 21 rotates, thereby conveying the material belt 100 between the two rollers downstream. When the material belt 100 is cut, the second roller 31 moves away from the first roller 21, facilitating the smooth winding of the tail of the material belt 100 after cutting.

[0070] In one embodiment, the second direction is perpendicular to the first direction, and the second roller 31 can move and adjust perpendicular to the conveying direction of the material belt 100. This facilitates the effective clamping of the material belt 100 by the second roller 31 after it approaches the first roller 21, reduces the deviation of the material belt 100 during clamping, and improves the compactness of the deviation correcting device.

[0071] In some embodiments, referring to Figure 3 , the first movable assembly 2 further includes a deviation correcting driving member 24. The deviation correcting plate 22 is provided with a moving block 221, and the deviation correcting driving member 24 is connected to the mounting seat 1 and drivingly connected to the moving block 221.

[0072] In this embodiment, the sliding of the deviation rectifying plate 22 relative to the first guide 11 is controlled by the deviation rectifying driving member 24, which ensures the accurate movement of the deviation rectifying plate 22 within a certain range, so that the deviation rectifying process of the first movable assembly 2 moving the material belt 100 along the width direction of the material belt 100 is more flexible, and the deviation rectifying accuracy and response speed are improved.

[0073] In some embodiments, the deviation rectifying driving member 24 can be a motor or a pneumatic cylinder, which drives the sliding of the deviation rectifying plate 22 relative to the first guide 11, so that the deviation can be corrected in a short time, and the quality and production efficiency of the battery cell product are ensured.

[0074] In some embodiments, referring to Figure 3 and Figure 4 , the deviation rectifying device further comprises a first air blowing member 26 connected to the deviation rectifying plate 22 and located at the bottom of the first roller 21.

[0075] In this embodiment, the first air blowing member 26 can blow air flow, which can have a certain rectifying effect on the material belt located below the first roller 21; when the material belt 100 deviates, the air flow generated by the first air blowing member 26 can push the material belt 100 back to the correct position, thereby enhancing the deviation rectifying effect.

[0076] In some embodiments, referring to Figure 3 and Figure 4 , the second movable assembly 3 comprises a driving member 32 connected to the mounting seat 1 and capable of driving the moving plate 33 to move in the second direction, and the second roller 31 is connected to the moving plate 33 through the movable member 332, so that the second roller 31 can approach or move away from the first roller 21.

[0077] In this embodiment, the driving member 32 can quickly respond to the control signal of the controller in the deviation rectifying device, such as a motor or a pneumatic cylinder, which effectively drives the moving plate 33 and the second roller 31 to adjust the position, facilitates the clamping of the material belt 100 by the first roller 21 and the second roller 31, and helps to correct the deviation in time during the transmission of the material belt 100, ensuring the accurate position of the material belt 100.

[0078] In some embodiments, referring to Figure 3 and Figure 7 , the deviation rectifying plate 22 is connected with a deviation rectifying transmission block 23, and the deviation rectifying transmission block 23 is provided with a guide groove 231 parallel to the second direction;

[0079] The movable member 332 is provided with a guide wheel 331 which is in rolling cooperation with the guide groove 231.

[0080] In this embodiment, the deviation correction driving block 23 can be connected with the deviation correction plate 22 to ensure the structural integrity of the deviation correction plate 22; or the deviation correction driving block 23 can be detachably connected with the deviation correction plate 22 to facilitate the installation and replacement of the deviation correction driving block 23.

[0081] The deviation correction driving block 23 can extend from the side of the deviation correction plate 22 to facilitate the connection between the moving plate 33 and the deviation correction plate 22. The guide groove 231 on the deviation correction driving block 23 provides a clear moving path for the guide wheel 331, ensuring the accuracy of the moving direction of the moving plate 33 and the second roller 31 during the deviation correction process, which helps to reduce the deviation error caused by inaccurate moving path.

[0082] Moreover, the rolling cooperation between the guide wheel 331 and the guide groove 231 makes the movement of the moving plate 33 more stable and continuous, ensuring the stability of the first roller 21 and the second roller 31 clamping the material belt 100.

[0083] In some embodiments, referring to Figure 4 and Figure 5 the deviation correction device further comprises a first connecting seat 35 and a first pneumatic element 36, the second roller 31 is connected to the moving plate 33 through the first connecting seat 35, and the first pneumatic element 36 is used to drive the first connecting seat 35 to move towards or away from the first roller 21.

[0084] In this embodiment, the first pneumatic element 36 such as a cylinder or a gas pump can quickly respond to the control signal of the controller to drive the first connecting seat 35 and the second roller 31 to approach or move away from the first roller 21. Through the position adjustment of the second roller 31, the clamping and releasing of the first roller 21 and the second roller 31 to the material belt 100 can be realized, which improves the flexibility and adaptability of the deviation correction.

[0085] Moreover, in the case that the driving element 32 drives the moving plate 33 to move, the first pneumatic element 36 and the driving element 32 cooperate to realize the phased adjustment of the second roller 31 approaching or moving away from the first roller 21; for example, the driving element 32 drives the moving plate 33 to move to realize the coarse adjustment of the position of the second roller 31, and the first pneumatic element 36 drives the first connecting seat 35 and the second roller 31 to move to realize the fine adjustment of the position of the second roller 31.

[0086] In addition, through the accurate control of the first pneumatic element 36 on the position of the second roller 31, on the basis of realizing that the second roller 31 can approach or move away from the first roller 21, the rigid contact between the two rollers can be avoided, and the stability of the action of the second roller 31 can be ensured.

[0087] In one embodiment, the adjustment accuracy of the first pneumatic element 36 is greater than that of the driving element 32, and through two-stage adjustment with different accuracies, the accuracy of the position adjustment of the second roller 31 can be ensured.

[0088] In some embodiments, referring to Figure 5 The deviation rectifying device further comprises a second guide 39 connected to the moving plate 33 and arranged in a second direction.

[0089] The first connecting seat 35 is slidingly connected to the second guide 39.

[0090] In this embodiment, the second guide 39 provides a clear movement path for the first connecting seat 35, ensuring the accuracy of the moving direction of the moving plate 33 and the second roller 31 during deviation rectification, and enhancing the stability of the entire second movable assembly 3, which can prevent deviation errors caused by unstable movement of the first connecting seat 35.

[0091] In some embodiments, referring to Figure 5 The second movable assembly 3 further comprises a film laminating roller 34, a second connecting seat 37, and a second pneumatic device 38, the film laminating roller 34 is connected to the bottom of the second roller 31 through the second connecting seat 37, and the second pneumatic device 38 is used to drive the second connecting seat 37 to move towards or away from the diaphragm 200.

[0092] The film laminating roller 34 is configured to abut against the diaphragm 200.

[0093] In the above embodiment, the second pneumatic device 38 such as a pneumatic cylinder or a pneumatic pump can quickly respond to the control signal of the controller, and then drive the second connecting seat 37 and the film laminating roller 34 to move towards or away from the diaphragm 200, so as to realize the position adjustment of the film laminating roller 34, and ensure the efficiency and stability of the winding of the material belt 100 and the diaphragm 200.

[0094] In some embodiments, referring to Figure 5 The deviation rectifying device further comprises a second blowing device 30 connected to the moving plate 33 and located at the bottom of the film laminating roller 34.

[0095] In this embodiment, since the second roller 31 and the film laminating roller 34 both belong to the second movable assembly 3, the second roller 31 and the film laminating roller 34 can simultaneously move away from or close to the first roller 21, avoiding the cut material belt tail to fall on the film laminating roller 34 downstream of the first roller 21 and the second roller 31, and ensuring the efficiency of the material belt 100 transmission.

[0096] In addition, when the next material belt is wound, the film laminating roller 34 can timely abut against the diaphragm 200, avoiding the film laminating roller 34 waiting for too long, ensuring the stability of the diaphragm 200 transmission, helping to fix the position of the material belt 100, and improving the efficiency of the battery cell winding.

[0097] Referring to Figure 3 and Figure 5The second blowing member 30 is located at the bottom of the film-rolling roller 34, and the first blowing member 26 and the second blowing member 30 are oppositely matched. After the tail part of the material belt is wound, the subsequent material belt is sent to the downstream between the first roller 21 and the second roller 31. At this time, the first blowing member 26 and the second blowing member 30 blow air to the head end of the subsequent material belt, so that the subsequent material belt is attached to the diaphragm. Then, the film-rolling roller 34 acts and is arranged on the surface of the diaphragm, so as to ensure the efficiency and stability of the winding of the material belt and the diaphragm.

[0098] In some embodiments, referring to Figure 6 The deviation rectifying device further comprises a material supporting assembly 4 connected to the mounting base 1 and used for supporting the tail part of the cut material belt.

[0099] In this embodiment, the material supporting assembly 4 can comprise a movable supporting plate, which is extended when the tail part of the material belt needs to be supported, and is retracted when the tail part of the material belt does not need to be supported, so as to avoid interference with the transmission of the material belt while ensuring the effectiveness of the support of the tail part of the material belt. Alternatively, the material supporting assembly 4 can comprise a fixed supporting plate, which is fixed relative to the mounting base 1 to ensure the stability of the support of the tail part of the material belt.
