[0037] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0038] Reference below Figure 1-Figure 3A tab flattening device 100 according to an embodiment of the present invention is described.

[0039] Combination Figure 1-Figure 3 As shown, the tab flattening device 100 according to the utility model can mainly include: a support assembly 10, an adjustment assembly 20 and a clamping assembly 30. Among them, the adjustment assembly 20 is arranged on the support assembly 10, at least part of the adjustment assembly 20 can move laterally relative to the support assembly 10, and at least part of the adjustment assembly 20 can rotate relative to the support assembly 10, and the clamping assembly 30 is arranged above the adjustment assembly 20, so that the adjustment assembly 20 drives the clamping assembly 30 to move laterally or rotate circumferentially relative to the support assembly 10, and the clamping assembly 30 is suitable for clamping the lateral edge of the pole piece 200.

[0040] Specifically, by setting the adjustment component 20 on the support component 10, and setting the clamping component 30 on the adjustment component 20, the support component 10 can support and fix the adjustment component 20 and the clamping component 30, and make at least a part of the adjustment component 20 move laterally relative to the support component 10, so that the adjustment component 20 can drive the clamping component 30 to move to the lateral sides of the pole piece 200, the clamping component 30 can clamp the lateral edge of the pole piece 200, the clamping component 30 can apply lateral friction force to the pole piece 200, and the pole piece 200 can move under the drive of the clamping component 30.

[0041] Considering that in the process of producing thin substrate multi-piece products of lithium batteries, the pole piece 200 is baked by a coater and rolled by a roller press. Since the lateral friction force exerted on the pole piece 200 by the clamping assembly 30 is too small, the middle pole ear 201 of the pole piece 200 cannot be fully flattened, and the middle pole ear 201 of the substrate is prone to wrinkling, curling and shrinking, and the slitting knife cannot cut the pole ear. This will greatly reduce the production efficiency and yield of the coater, roller press, and slitting machine equipment.

[0042] By making at least a portion of the adjustment component 20 rotatable relative to the support component 10, the adjustment component 20 can drive the clamping component 30 to rotate circumferentially relative to the support component 10, and the angle of the clamping component 30 relative to the support component 10 can be adjusted, so that the clamping component 30 can generate a relative sliding friction force F on the pole piece 200, and the sliding friction force F can be decomposed into a lateral outward component F1 and a lateral perpendicular component F2, wherein F1 can tighten the lateral edge of the pole piece 200, and F2 can drive the pole piece 200 to ensure the transportation of the pole piece 200, so that for multiple pole pieces 200 with intermediate pole ears 201, under the premise of ensuring the normal transportation of the pole pieces 200, the intermediate pole ears 201 can be indirectly tightened by tightening the pole piece 201, which can improve the wrinkling and shrinkage problems of the intermediate pole ears 201, reduce the number of belt breaks, improve production efficiency, and improve yield.

[0043] Therefore, by setting the adjustment component 20 on the support component 10, at least part of the adjustment component 20 can move laterally relative to the support component 10, and at least part of the adjustment component 20 can rotate relative to the support component 10, and the clamping component 30 is set above the adjustment component 20, so that the lateral displacement and rotation angle of the clamping component 30 can be adjusted. On the premise of ensuring the clamping effect on the pole piece 200, the lateral force of the clamping component 30 on the pole piece 200 is increased, thereby improving the flattening effect of the middle pole ear 201 of the pole piece 200.

[0044] Combination Figure 1 and Figure 2 As shown, there are two adjusting assemblies 20 and two clamping assemblies 30 , the two adjusting assemblies 20 are spaced apart in the lateral direction, and the two clamping assemblies 30 are connected to the two adjusting assemblies 20 respectively, so that the two clamping assemblies 30 clamp the edges of the pole piece 200 on both sides in the lateral direction.

[0045] Specifically, by arranging two adjustment components 20 on the support component 10 at intervals laterally, and connecting two clamping components 30 to the two adjustment components 20 accordingly, the lateral positions and rotation angles of the two clamping components 30 can be adjusted by the two adjustment components 20 respectively, and then the two clamping components 30 are respectively clamped on the lateral edges of the pole piece 200, and the two clamping components 30 respectively apply force on the lateral sides of the pole piece 200, thereby generating a lateral tightening effect on both sides of the pole piece 200, thereby improving the wrinkling and shrinkage problems of the middle pole ear 201, reducing the number of belt breaks, improving production efficiency, and improving yield.

[0046] Combination Figure 1 and Figure 2 As shown, the adjustment assembly 20 may include: a support seat 21 and a rotating shaft 22 , the support seat 21 may be laterally movably disposed on the support assembly 10 , the rotating shaft 22 may be rotatably disposed above the support seat 21 , and the rotating shaft 22 is connected and fixed to the clamping assembly 30 .

[0047] In this way, the support seat 21 can be moved laterally relative to the support assembly 10 to achieve the lateral movement of the adjustment assembly 20 as a whole relative to the support assembly 10, thereby driving the clamping assembly 30 to move laterally relative to the support assembly 10, so that the clamping assembly 30 is laterally close to the lateral edge of the pole piece 200, thereby facilitating the clamping assembly 30 to clamp the lateral edge of the pole piece 200.

[0048] Furthermore, the rotation of the rotating shaft 22 relative to the support seat 21 can drive the clamping assembly 30 to rotate relative to the support assembly 10, so that the clamping assembly 30 has a lateral outward component of force while clamping the edge of the pole piece 200, thereby achieving lateral tightening of the pole piece 200, which can improve the wrinkling and shrinkage problems of the middle pole ear 201, reduce the number of belt breaks, improve production efficiency, and improve yield.

[0049] Optionally, a matching groove may be provided on the rotating shaft 22 , and the support seat 21 of the clamping assembly 30 is disposed in the matching groove and is interference fit with the matching groove, thereby achieving connection and fixation between the rotating shaft 22 and the clamping assembly 30 .

[0050] Combination Figure 1 and Figure 2 As shown, the adjustment assembly 20 may also include: a transverse position locking member 23, which is suitable for locking the support seat 21 and the support assembly 10. Specifically, after the support seat 21 is moved laterally relative to the support assembly 10, the support seat 21 may also move in a manner not intended by the user, causing the pole piece 200 to be too loose or too tight in the transverse direction. By providing the transverse position locking member 23, the staff can lock the support seat 21 and the support assembly 10 by manipulating the transverse position locking member 23, thereby preventing the support seat 21 and even the clamping assembly 30 from moving laterally in a manner not intended by the user, ensuring that the clamping assembly 30 is always in the correct clamping position, ensuring the transverse tightening effect of the clamping assembly 30 on the pole piece 200, and improving the reliability of the tab flattening device 100.

[0051] Combination Figure 1 and Figure 2 As shown, the adjustment assembly 20 may further include: an angle adjustment member 24, which is connected to the rotating shaft 22 in a transmission manner to adjust the rotation angle of the rotating shaft 22. In this way, the staff can adjust the rotation angle of the rotating shaft 22 relative to the support assembly 10 by manipulating the angle adjustment member 24, thereby achieving precise control of the angle of the clamping assembly 30, and further improving the lateral tightening effect of the tab flattening device 100 on the pole piece 200. The angle adjustment member 24 may be an angle adjustment knob, and the rotation angle of the angle adjustment knob is consistent with the rotation angle of the rotating shaft 22, which is convenient for the staff to manipulate.

[0052] Combination Figure 1 and Figure 2 As shown, the adjustment assembly 20 may also include: an angle locking member 25, which is suitable for locking the rotating shaft 22 and the support seat 21. Specifically, after the rotating shaft 22 is rotated relative to the support seat 21 by a predetermined angle, the rotating shaft 22 may also rotate in a manner not intended by the user, causing the pole piece 200 to be too loose or too tight in the lateral direction. By providing the angle locking member 25, the staff can lock the rotating shaft 22 and the support seat 21 by manipulating the angle locking member 25, thereby preventing the rotating shaft 22 and even the clamping assembly 30 from rotating in a manner not intended by the user, ensuring that the clamping assembly 30 is always in the correct clamping position, ensuring the lateral tightening effect of the clamping assembly 30 on the pole piece 200, and improving the reliability of the tab flattening device 100.

[0053] Combination Figure 1and Figure 2 As shown, the clamping assembly 30 may include: a connecting member 31, an upper clamping roller 32 and a lower clamping roller 33, the connecting member 31 is fixedly connected to the adjustment assembly 20, the upper clamping roller 32 and the lower clamping roller 33 are both rotatably arranged on the connecting member 31, the upper clamping roller 32 is arranged above the lower clamping roller 33 at an interval, and one of the upper clamping roller 32 and the lower clamping roller 33 is movably arranged relative to the other in the up and down directions to selectively clamp the lateral edge of the pole piece 200.

[0054] In this way, when using the tab flattening device 100, the upper clamping roller 32 and the lower clamping roller 33 can be moved away from each other in the vertical direction first, and the spacing between the upper clamping roller 32 and the lower clamping roller 33 in the vertical direction can be increased, so that the lateral edge of the pole piece 200 can be placed between the upper clamping roller 32 and the lower clamping roller 33, and then the upper clamping roller 32 and the lower clamping roller 33 can be moved closer to each other in the vertical direction, and the spacing between the upper clamping roller 32 and the lower clamping roller 33 in the vertical direction can be adjusted. The lateral edge of the pole piece 200 is clamped, and the upper clamping roller 32 and the lower clamping roller 33 roll in opposite directions, so that the pole piece 200 and the upper clamping roller 32 and the lower clamping roller 33 generate relative movement, and the sliding friction force generated in the lateral direction acts on the pole piece 200 and generates a lateral outward component of force, thereby ensuring that the pole piece 200 is laterally tightened by the pole piece flattening device 100, thereby realizing the transportation of the pole piece 200 by the pole piece flattening device 100, and further ensuring the normal operation of the pole piece flattening device 100.

[0055] Specifically, combined Figure 1 and Figure 2 As shown, the connecting member 31 may include: a first plate portion 311 and a second plate portion 312, the first plate portion 311 is extended in the up-down direction, and the second plate portion 312 is extended in the transverse direction and connected to the lower end of the first plate portion 311. The clamping assembly 30 may also include: an upper clamping roller mounting seat 321 and a lower clamping roller mounting seat 331, the upper clamping roller mounting seat 321 and the lower clamping roller mounting seat 331 are arranged at intervals in the up-down direction, the upper clamping roller mounting seat 321 is movably arranged on the first plate portion 311, the lower clamping roller mounting seat 331 is movably arranged on the second plate portion 312, the upper clamping roller 32 is rotatably arranged on the upper clamping roller mounting seat 321, and the lower clamping roller 33 is rotatably arranged on the lower clamping roller mounting seat 331.

[0056] In this way, under the premise of ensuring that the upper clamping roller 32 and the lower clamping roller 33 are respectively rotatable, it is only necessary to drive the upper clamping roller mounting seat 321 to realize the movement of the upper clamping roller 32 in the up and down directions, and it is only necessary to drive the lower clamping roller mounting seat 331 to realize the movement of the lower clamping roller 33 in the up and down directions, thereby making the structure of the clamping assembly 30 more stable and reliable.

[0057] Combination Figure 1 and Figure 2As shown, at least one of the upper clamping roller 32 and the lower clamping roller 33 is provided with a step portion 322 , which is located at the part of the upper clamping roller 32 and the lower clamping roller 33 facing laterally outward, and the step portion 322 is suitable for avoiding the edge pole ear 202 of the pole piece 200 .

[0058] Specifically, the lateral edge of the pole piece 200 is also provided with a pole ear, and the edge pole ear 202 protrudes outside the lateral edge of the pole piece 200. By providing a step portion 322 on at least one of the upper clamping roller 32 and the lower clamping roller 33, the step portion 322 is located in the part of the upper clamping roller 32 and the lower clamping roller 33 facing laterally outward, so that the position of the upper clamping roller 32 and the lower clamping roller 33 corresponding to the step portion 322 can form an avoidance gap, thereby avoiding the edge pole ear 202 of the pole piece 200 and avoiding clamping the edge pole ear 202, which can further improve the reliability of the pole ear flattening device 100.

[0059] Combination Figure 1 and Figure 2 As shown, the clamping assembly 30 may also include: a first fixed plate 34 and a driving member 35, the first fixed plate 34 is extended in the transverse direction and connected to the upper end of the first plate portion 311, the upper clamping roller mounting seat 321 is spaced apart below the first fixed plate 34, the driving member 35 is arranged on the first fixed plate 34 and is transmission-connected to the upper clamping roller mounting seat 321 to drive the upper clamping roller mounting seat 321 to move up and down.

[0060] Specifically, by setting the first fixed plate 34, the first fixed plate 34 can be used to set the driving member 35, and the upper clamping roller mounting seat 321 is spaced above the first fixed plate 34, so that the driving member 35 is connected to the upper clamping roller mounting seat 321 through transmission, thereby realizing the driving of the upper clamping roller mounting seat 321 in the up and down directions, and making the up and down movement of the upper clamping roller mounting seat 321 and even the upper clamping roller 32 simpler and more reliable.

[0061] Among them, the driving member 35 can be a cylinder, which includes a cylinder body and a piston rod. The piston rod moves up and down relative to the cylinder body. By connecting the cylinder body to the first fixed plate 34 and connecting the end of the piston rod located on the outside to the upper clamping roller mounting seat 321, the upper clamping roller mounting seat 321 and even the upper clamping roller 32 can be driven to move up and down.

[0062] Furthermore, a cylinder valve switch and a cylinder proportional regulating valve can be set. The cylinder switch valve can control the opening and closing of the cylinder and adjust the opening and closing of the upper clamping roller 32 relative to the lower clamping roller 33. The cylinder proportional regulating valve can adjust the air pressure. In this way, the tightness between the upper clamping roller 32, the lower clamping roller 33 and the pole piece 200 can be adjusted, so that the tightness adjustment of the clamping assembly 30 is more precise, and the clamping effect of the clamping assembly 30 on the pole piece 200 can be made more stable.

[0063] Combination Figure 1 and Figure 2 As shown, the clamping assembly 30 may further include: a guide rod 36, a guide hole 341 is provided on the first fixing plate 34, one end of the guide rod 36 is connected to the upper clamping roller mounting seat 321, and the other end of the guide rod 36 is penetrated by the guide hole 341 and guided and matched with the guide hole 341. Specifically, by providing the guide rod 36 and providing the guide hole 341 on the first fixing plate 34, when the driving member 35 drives the upper clamping roller mounting seat 321 and even the upper clamping roller 32 to move up and down, the guide rod 36 can be guided and matched with the guide hole 341 in the up and down direction, so that the up and down movement of the upper clamping roller mounting seat 321 and even the upper clamping roller 32 can be more stable and reliable.

[0064] Combination Figure 1 and Figure 2 As shown, the clamping assembly 30 may further include: an abutment block 37, which is disposed below the lower clamping roller mounting seat 331 in a transversely movable manner and abuts with the lower clamping roller mounting seat 331 to drive the lower clamping roller mounting seat 331 to move up and down. Specifically, by disposing the abutment block 37 below the lower clamping roller mounting seat 331 in a transversely movable manner and abutting with the lower clamping roller mounting seat 331, when the abutment block 37 moves transversely below the lower clamping roller mounting seat 331, an abutment force can be applied to the lower clamping roller mounting seat 331, and the abutment force has an upward component, so that the lower clamping roller mounting seat 331 and even the lower clamping roller 33 can be driven to move up and down, so that the realization of the up and down movement of the lower clamping roller 33 can be made simpler and more reliable.

[0065] Furthermore, combined with Figure 1 and Figure 2 As shown, the lower roller mounting seat 331 is provided with an abutting portion 332, and the abutting block 37 and the abutting portion 332 abut against each other and form an abutting surface 371. The abutting surface 371 is extended in the lateral direction, and the abutting surface 371 gradually moves away from the lower roller mounting seat 331 in the lateral outward direction, or the abutting surface 371 gradually approaches the lower roller mounting seat 331 in the lateral outward direction, that is, the abutting surface 371 is extended in the lateral direction and is inclined, and the abutting surface 371 can be a plane or an arc surface, so that when the abutting block 37 moves laterally below the lower roller mounting seat 331, not only can the abutting block 37 actually exert an upward component force on the lower roller mounting seat 331, but also the movement of the abutting block 37 can be smoother.

[0066] Combination Figure 1 and Figure 2As shown, the clamping assembly 30 may further include: a lower clamping roller adjusting member 38, which is disposed on the connecting member 31 and is transmission-connected to the abutting block 37 to drive the abutting block 37 to move laterally relative to the lower clamping roller mounting seat 331. In this way, the staff can adjust the lateral displacement of the abutting block 37 relative to the lower clamping roller mounting seat 331 by manipulating the lower clamping roller adjusting member 38, thereby achieving precise control of the up and down movement distance of the lower clamping roller mounting seat 331 and even the lower clamping roller 33, ensuring that the clamping assembly 30 clamps the pole piece 200, and further improving the lateral tightening effect of the tab flattening device 100 on the pole piece 200.

[0067] The lower clamping roller adjusting member 38 may be a lower clamping roller adjusting knob, and the lateral displacement of the abutment block 37 relative to the lower clamping roller mounting seat 331 may be adjusted by adjusting the rotation angle of the lower clamping roller adjusting knob.

[0068] Combination Figure 1 and Figure 2 As shown, the clamping assembly 30 may also include: a second fixed plate 39, which is extended in the up-down direction and connected to the lateral end of the second plate portion 312 away from the first plate portion 311, and the lateral sides of the lower clamping roller mounting seat 331 are respectively slidably matched with the first plate portion 311 and the second fixed plate 39 in the up-down direction, and the lower clamping roller adjustment member 38 is arranged on the second fixed plate 39.

[0069] Specifically, by setting the second fixing plate 39, the second fixing plate 39 and the first plate portion 311 are spaced apart in the horizontal direction, so that the lower clamping roller mounting seat 331 is located in the horizontal direction between the second fixing plate 39 and the first plate portion 311, and the lateral sides of the lower clamping roller mounting seat 331 are respectively slidably matched with the first plate portion 311 and the second fixing plate 39 in the up and down directions, so that when the lower clamping roller mounting seat 331 moves up and down under the action of the abutment block 37, one side of the lower clamping roller mounting seat 331 is slidably matched with the first plate portion 311 in the up and down directions, and the other side of the lower clamping roller mounting seat 331 is slidably matched with the second fixing plate 39 in the up and down directions, thereby limiting the moving path of the lower clamping roller mounting seat 331, and making the up and down movement of the lower clamping roller mounting seat 331 and even the lower clamping roller 33 more stable and smooth.

[0070] Furthermore, the lower clamping roller adjusting member 38 may also be disposed on the second fixed plate 39 , which can increase the controllable space of the lower clamping roller adjusting member 38 and further optimize the structural design of the clamping assembly 30 and even the tab flattening device 100 .

Specifically, by extending the support shaft 11 in the horizontal direction, the two ends of the support shaft 11 are respectively connected to the two fixed seats 12, so that the fixed seat 12 can be connected with other devices to achieve the installation of the tab flattening device 100. In addition, the support shaft 11 can pass through the support seat 21 of the support assembly 10, and the support seat 21 can slide with the support shaft 11 in the horizontal direction, so that the lateral movement of the support seat 21 relative to the support assembly 10 can be realized more simply and conveniently.

[0072] Combination Figure 1 and Figure 2 As shown, the support assembly 10 may further include: a connecting seat 13, at least two supporting shafts 11, at least two supporting shafts 11 passing through the connecting seat 13 and being arranged parallel to each other and spaced apart. Specifically, at least two supporting shafts 11 may be arranged, and at least two supporting shafts 11 may be arranged in parallel, so that at least two supporting shafts 11 may pass through the supporting seat 21 of the adjusting assembly 20 at the same time, and at least two supporting shafts 11 may support the supporting seat 21, which may not only improve the supporting force of the support assembly 10 on the adjusting assembly 20, but also improve the stability and smoothness of the lateral movement of the supporting seat 21 relative to the supporting shaft 11.

[0073] Furthermore, by providing a connecting seat 13 and allowing at least two supporting shafts 11 to pass through the connecting seat 13 , the parallelism of at least two supporting shafts 11 can be ensured, thereby optimizing the structural design of the supporting assembly 10 and improving the reliability of the supporting assembly 10 .
