[0043] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0044] Reference Figure 1 This application provides a winding device, which includes:

[0045] Base 1;

[0046] Support 2, the support 2 is installed on the base 1 and can be inserted through the large plate 200;

[0047] Needle winding assembly 3 is rotatably connected to support base 2.

[0048] In this embodiment, the base 1 can serve as the basic structure of the winding device to provide installation positions and stable support for other structures on the winding device; moreover, during the rotation and movement of the winding needle structure in the winding device, the base 1 can provide a stable and reliable operating environment to ensure the stable operation of the winding device.

[0049] In this embodiment, the large plate 200 provides structural support, an operating platform, and sheet transport functions for the winding device, and the base 1 can be fixedly installed on the large plate 200. The support seat 2 is installed on the base 1 to ensure the stability of the support seat 2; the support seat 2 passes through the large plate 200 and can extend to both sides of the large plate 200, providing support for the needle winding assembly 3 on both sides of the large plate 200, so that the needle winding assembly 3 can move from one side of the large plate 200 to the other side of the large plate 200.

[0050] See Figure 1 The needle winding assembly 3 is rotatably connected to the support base 2 and has a winding station, an adhesive application station, and a blanking station. For example, when the needle winding assembly 3 rotates to the winding station, it can wind sheets such as electrode plates and separators to ensure tight adhesion between the electrode plates and separators, so as to obtain a bare cell with a certain thickness and structure. When the needle winding assembly 3 rotates to the adhesive application station, it conveys the wound bare cell to the area below the adhesive application or application device to apply glue or tape to the adhesive application position of the cell. When the needle winding assembly 3 rotates to the blanking station, the wound cell can be removed from the needle winding assembly 3 to facilitate subsequent assembly or testing of the cell.

[0051] In this embodiment, the support base 2 is inserted through the large plate 200 to facilitate the adjustment of the perpendicularity between the winding needle assembly 3 and the large plate 200. This reduces the processing precision of the large plate 200 while simplifying the assembly difficulty of the winding device.

[0052] In one embodiment, see Figure 3 and Figure 4 In this embodiment, the support base 2 is adjustablely mounted on the base 1 and can pass through the large plate 200. By adjusting the perpendicularity between the winding needle assembly 3 and the large plate 200, it is not necessary to fix the support base in the mounting hole on the large plate 200. With the adjustable support base, the position of the support base on the base can be adjusted, thereby adjusting the perpendicularity between the winding needle assembly and the large plate. This can reduce the processing precision of the large plate 200 while ensuring the perpendicularity between the winding needle assembly 3 and the large plate 200, improving the winding precision of the winding device for sheets such as electrodes, separators or battery cells, and reducing winding errors.

[0053] In one embodiment, the support base 2 is integrally cast, which simplifies the structure of the support base 2, reduces the number of assembly parts of the winding device, reduces the assembly error of the winding device, and improves the assembly efficiency and structural strength of the winding device.

[0054] In some embodiments, see Figure 1 The winding device includes an adjustment component 4, which is disposed on the base 1 and used to adjust the position of the support 2 so that the winding needle assembly 3 is at a set angle relative to the large plate 200.

[0055] In the above embodiments, the adjustment component 4 can effectively adjust the height of the support seat 2 relative to the base 1, for example, by adjusting the height of the support seat 2 and the tilt angle of the support seat 2 relative to the base 1 through a structure such as a motor or cylinder, so as to realize the flexible adjustment of the position of the support seat 2, thereby keeping the needle winding component 3 at a set angle relative to the large plate 200.

[0056] In one embodiment, Figure 4 This is a top view of the winding device; the axial direction of the needle winding assembly 3 can be... Figure 4 In the X-axis direction, the needle of the needle winding assembly 3 can move along the X-axis and rotate around the X-axis; in the Y-axis direction... Figure 4 In the direction perpendicular to the X-axis, the adjustment component 4 can adjust the position parameters such as the height and tilt angle of the support seat 2, thereby keeping the needle winding component 3 perpendicular to the large plate 200, that is, the axis of the needle winding component 3 is perpendicular to the large plate 200.

[0057] In one embodiment, see Figure 1 and Figure 6 The adjustment assembly 4 includes a base plate 41 and an adjustment member 42. The base plate 41 is disposed on the base 1 and has a first inclined surface 412 facing away from the base 1. At least a portion of the adjustment member 42 is sandwiched between the base plate 41 and the support 2 and has a second inclined surface that fits against the first inclined surface 412.

[0058] The adjusting member 42 can slide relative to the base plate 41 to move the support 2 away from or closer to the base plate 41.

[0059] In this embodiment, a plurality of base plates 41 can be fixedly provided on the upper surface of the base 1, and the support seat 2 is installed on the base plate 41. An adjustment member 42 is provided between the support seat 2 and the base plate 41. The base plate 41 and the adjustment member 42 are engaged by the abutment of the first inclined surface 412 and the second inclined surface, so as to facilitate the adjustment of the height and tilt angle of the support seat 2 relative to the base 1. The base 1 and the large plate 200 are fixedly provided relative to each other, and the needle winding assembly 3 is provided on the support seat 2, so the perpendicularity between the needle winding of the needle winding assembly 3 and the large plate 200 can be adjusted.

[0060] Specifically, see Figure 6 The adjusting member 42 has a second inclined surface facing the base plate 41, that is, the second inclined surface of the adjusting member 42 is... Figure 4 The XOY planes intersect, and the surface of the adjusting member 42 facing away from the base plate 41 is a plane, that is, this plane intersects with... Figure 4The XOY planes are parallel, causing the thickness of the part of the adjusting member 42 between the base plate 41 and the support 2 to gradually change. By sliding the adjusting member 42 relative to the base plate 41, the distance between the support 2 and the base plate 41 can be increased or decreased, so that the support 2 moves away from or closer to the base plate 41, thereby achieving the purpose of adjusting the position of the support 2 and realizing the adjustment of the angle between the needle winding assembly 3 and the large plate 200.

[0061] Furthermore, the adjustment component 42 and the base plate 41 are fitted together by an inclined surface, making the adjustment process more stable and easier to control. By finely adjusting the position of the adjustment component 42, the height and tilt angle of the support 2 can be precisely adjusted.

[0062] In some embodiments, see Figure 6 The adjusting component 4 includes an adjusting screw 43, the adjusting component 42 includes an adjusting plate 421 and a connecting plate 422, the second inclined surface is located on the adjusting plate 421, the adjusting plate 421 is sandwiched between the base plate 41 and the support seat 2, and the adjusting screw 43 passes through the connecting plate 422 and is connected to the support seat 2.

[0063] In this embodiment, the adjusting plate 421 and the connecting plate 422 are bent relative to each other, for example, to form an L-shaped adjusting member 42; the adjusting plate 421 and the connecting plate 422 are combined together to form a compact adjusting structure, which not only saves the setting space, but also makes the entire winding device more compact.

[0064] See Figure 6 The adjusting screw 43 is screwed to the support base 2 through the connecting plate 422, and the adjusting screw 43 abuts against the connecting plate 422. By rotating the adjusting screw 43, the connecting plate 422 of the adjusting member 42 can be pushed to move, so that the adjusting plate 421 of the adjusting member 42 applies an upward thrust to the support base 2, so as to precisely control the distance between the support base 2 and the base plate 41, thereby ensuring that the needle winding assembly 3 reaches the required height and tilt angle, and ensuring the perpendicularity between the needle on the needle winding assembly 3 and the large plate 200.

[0065] In some specific embodiments, see Figure 6 The adjusting component 4 includes multiple adjusting screws 43, which pass through the connecting plate 422 and are connected to the support base 2. A top rod 44 is provided between adjacent adjusting screws 43. One end of the top rod 44 is screwed to the connecting plate 422, and the other end of the top rod 44 abuts against the support base 2. By rotating the adjusting screws 43, the connecting plate 422 of the adjusting component 42 can be pushed to move closer to the support base 2. By rotating the top rod 44, the connecting plate 422 of the adjusting component 42 can be pushed to move away from the support base 2, so as to maintain the stability of the relative position between the adjusting component 42 and the support base 2.

[0066] In another embodiment, the adjustment member 42 and the base plate 41 can be moved by a drive structure such as a motor or cylinder, which can also achieve the adjustment of the height and tilt angle of the needle winding assembly 3.

[0067] In some embodiments, see Figure 6 The base plate 41 is provided with a limiting shaft 411, and the support seat 2 is provided with an adjustment hole 21. The limiting shaft 411 passes through the adjustment hole 21 and is clearance-fitted with the adjustment hole 21.

[0068] In the above embodiment, the limiting shaft 411 on the base plate 41 can be a screw or a pin, and the support seat 2 can be provided with a long waist-shaped hole or a rectangular hole. The limiting shaft 411 is provided in the adjustment hole 21 to prevent the support seat 2 from coming off the base plate 41.

[0069] When adjusting the position of the support base 2 by adjusting the component 4, the clearance fit between the limiting shaft 411 and the adjusting hole 21 not only allows the support base 2 to move in a direction perpendicular to the XOY plane, but also allows the support base 2 to swing around the Y axis, so that the height and tilt angle of the support base 2 can be flexibly adjusted.

[0070] In some embodiments, see Figure 4 The adjustment component 4 includes a first adjustment component 401 and a second adjustment component 402. The first adjustment component 401 and the second adjustment component 402 are disposed on opposite sides of the support base 2 and can adjust the height position of the support base 2.

[0071] In the above embodiments, the first adjustment component 401 and the second adjustment component 402 can adopt the structure of the base plate 41 and the adjustment component 42 cooperating with the inclined surface. The support base 2 has a first side and a second side. The first adjustment component 401 is disposed on the first side of the support base 2, and the second adjustment component 402 is disposed on the second side of the support base 2. By adjusting the first adjustment component 401 and the second adjustment component 402 at the same time, the height position of the support base 2 can be controlled more precisely. Moreover, this dual-sided adjustment method helps to ensure the stability of the support base 2 in the direction perpendicular to the XOY plane and avoids the support base 2 from shaking or tipping over during the adjustment process.

[0072] In some embodiments, see Figure 4 The adjustment component 4 includes a third adjustment component 403, which is disposed between the first adjustment component 401 and the second adjustment component 402, and is connected to the first adjustment component 401 and the second adjustment component 402 on different sides of the support base 2.

[0073] In the above embodiments, the third adjustment component 403 can adopt the structure of the base plate 41 and the adjustment component 42 with inclined surfaces. The support base 2 has a third side with opposite sides, which is adjacent to the first side and the second side. The third adjustment component 403 is set corresponding to the third side of the support base 2. By coordinating the adjustment between the first adjustment component 401, the second adjustment component 402 and the third adjustment component 403, the height position of the support base 2 can be controlled more precisely, and the stability of the adjustment of the support base 2 can be improved.

[0074] In some embodiments, see Figure 4 The first adjustment component 401 includes a first sub-component 4011 and a second sub-component 4012. The first sub-component 4011 and the second sub-component 4012 are spaced apart and disposed on the same side of the support base 2 and are capable of adjusting the tilt angle of the support base 2.

[0075] And / or, the second adjustment component 402 includes a third sub-component and a fourth sub-component, which are spaced apart on the same side of the support 2 and are capable of adjusting the tilt angle of the support 2.

[0076] In the above embodiments, when it is necessary to adjust the tilt angle of the support base 2 to ensure the perpendicularity of the needle winding assembly 3 and the large plate 200, the first sub-assembly 4011 and the second sub-assembly 4012 are adjusted on the same side of the support base 2, and the adjustment heights of the first sub-assembly 4011 and the second sub-assembly 4012 are different, so as to achieve the adjustment of the tilt angle of the support base 2, and also to ensure that the support base 2 remains stable during the tilting process.

[0077] In the above embodiments, the tilt angle of the support base 2 can also be adjusted by the second adjustment component 402, or by the cooperation of the second adjustment component 402 and the first adjustment component 401. Specifically, the third sub-component and the fourth sub-component are adjusted on the same side of the support base 2, and the adjustment heights of the third sub-component and the fourth sub-component are different, so as to realize the adjustment of the tilt angle of the support base 2 and ensure the adjustment stability of the support base 2.

[0078] In addition, the third adjustment component 403 may also include a fifth sub-component and a sixth sub-component. The fifth sub-component and the sixth sub-component are spaced apart on the same side of the support 2 and can adjust the tilt angle of the support 2, thereby improving the flexibility of the adjustment of the support 2.

[0079] In some embodiments, the first sub-assembly 4011 includes a plurality of adjusting screws 43 and a push rod 44. The adjusting screws 43 pass through the connecting plate 422 and are connected to the support base 2. The push rods 44 are disposed between adjacent adjusting screws 43. One end of the push rod 44 is screwed to the connecting plate 422, and the other end of the push rod 44 abuts against the support base 2. By rotating the adjusting screws 43, the connecting plate 422 of the adjusting member 42 can be pushed to move closer to the support base 2. By rotating the push rods 44, the connecting plate 422 of the adjusting member 42 can be pushed to move away from the support base 2, so as to maintain the stability of the relative position between the adjusting member 42 and the support base 2.

[0080] In one embodiment, see Figure 4 The winding device includes a position adjustment member 8, which is disposed on at least one of the first, second and third sides of the support base 2 to adjust the position of the support base 2 in the X-axis direction and the Y-axis direction, thereby achieving the purpose of adjusting the position of the winding needle in the winding needle assembly 3 in the X-axis direction and the Y-axis direction.

[0081] In some embodiments, see Figure 1 and Figure 5 The needle coil assembly 3 includes a flange structure 31 and a needle coil 32. The flange structure 31 is rotatably connected to the support base 2, and the needle coil 32 is connected to the flange structure 31. The needle coil 32 can switch between the two sides of the large plate 200.

[0082] In the above embodiment, the flange structure 31 is rotatably connected to both ends of the support base 2. The flange structure 31 includes a first flange 311, a second flange 312, a connector 313, and a support shaft 314. The first flange 311 and the second flange 312 are connected by the connector 313. The centers of the first flange 311 and the second flange 312 are supported by the support shaft 314, and the support shaft 314 extends from both ends of the first flange 311 and the second flange 312. The two ends of the support shaft 314 are rotatably connected to the support base 2.

[0083] In one specific embodiment, see Figure 1 and Figure 5 The flange structure 31 also includes a connecting sleeve 315, which is sleeved on the support shaft 314 and one end is connected to the second flange 312. The other end of the connecting sleeve 315 is connected to the support part 9. The two ends of the coil needle 32 are respectively connected to the flange structure 31 and the support part 9 to ensure the stability of the coil needle 32 during rotation.

[0084] In one embodiment, the first flange 311, the second flange 312, the connector 313, and the connecting bushing 315 are integrally cast. The support shaft 314 is inserted into the first flange 311 and the second flange 312 and connected to the first flange 311 and the second flange 312 through a transmission key, ensuring the synchronicity of the rotation of the first flange 311 and the second flange 312 with the support shaft 314.

[0085] In another embodiment, the first flange 311, the second flange 312, the connector 313, the connecting bushing 315, and the support shaft 314 are integrally cast, which makes the structure of the flange structure 31 simple, reduces the number of assembly parts of the winding device, reduces the assembly error of the winding device, and improves the assembly efficiency and structural strength of the winding device.

[0086] In one embodiment, see Figure 1 A needle winding self-rotation drive assembly 6 is installed on the flange structure 31. The needle winding self-rotation drive assembly 6 is connected to the needle winding 32. The needle winding self-rotation drive assembly 6 drives the needle winding 32 to rotate, which facilitates the winding of the sheet on the needle winding 32. A needle winding revolution drive assembly 7 is installed on the support base 2. The needle winding revolution drive assembly 7 drives the flange structure 31 to revolution, and at the same time drives the needle winding 32 to revolution, so as to realize the adjustment of the needle winding assembly 3 at different working positions.

[0087] In one embodiment, see Figure 2 The support base 2 is provided with a support structure 22, which includes a support plate 221 and multiple support wheels 222. The support wheels 222 are rotatably connected to the support plate 221 and cooperate with the needle winding assembly 3.

[0088] See Figure 2 A support plate 221 is installed on the support base 2, and multiple support wheels 222 are rotatably installed on the support plate 221. The second flange 312 of the needle winding assembly 3 abuts against the support wheels 222. When the needle winding assembly 3 rotates, the support wheels 222 rotate synchronously to ensure the stable support of the needle winding assembly 3 while ensuring the adjustment of the needle winding assembly 3 position.

[0089] In some embodiments, see Figure 2 The support base 2 includes a base plate 23 and a frame 24. The base plate 23 has an adjustment block 231, which is used to adjust the position of the support base 2 on the base 1. For example, the adjustment block 231 is attached to the side of the adjustment component 42 of the adjustment assembly 4 away from the base plate 41. The frame 24 is provided with a connection hole 241, and the needle winding assembly 3 is rotatably connected to the connection hole 241.

[0091] The adjustment block 231 facilitates the fine-tuning of the height or tilt angle of the support base 2 by the adjustment component 42, and the close fit between the adjustment block 231 and the adjustment component 42 improves the stability of the entire structure. At the same time, the connecting hole 241 on the frame 24 provides a rotation connection point for the needle winding assembly 3, allowing the needle winding assembly 3 to rotate smoothly around the connecting hole 241.

[0092] This application provides a winding machine, which includes a large plate 200 and the winding device 100 described above;

[0093] The support base 2 passes through the large plate 200 and extends from both sides of the large plate 200.

[0094] In the above embodiments, the winding device 100 adjusts the perpendicularity between the winding needle assembly 3 and the large plate, eliminating the need to fix the support base in the mounting holes on the large plate. This reduces the processing precision of the large plate while ensuring the perpendicularity between the winding needle assembly 3 and the large plate, thereby improving the winding precision of the winding device for sheets such as electrodes, separators, or battery cells and reducing winding errors.

[0095] The winding machine can be used to wind the electrodes and separators of lithium batteries, or to wind other sheets. The embodiments of this application do not limit the objects to be wound.

[0096] In one embodiment, see Figure 3 The base 1 is fixed to the large plate 200.

[0097] In this embodiment, the fixed large plate 200 can provide support for the base 1 and the support 2, making it easy for the needle winding assembly 3 on the support 2 to move from one side of the large plate 200 to the other side of the large plate 200, while ensuring the stability of the base 1.

[0098] In some embodiments, see Figure 1 and Figure 3 It also includes a support member 5, with one side of the base 1 fixed to the large plate 200 and the support member 5 supported on the other side of the base 1.

[0099] In the above embodiment, one side and the other side of the base 1 can be opposite sides of the base 1. The base 1 is also provided with a support member 5, which is connected to the frame connected to the large plate 200 to avoid the base 1 forming a cantilever structure and to support the overall structure of the winding device.
