[0068] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0069] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0070] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0071] Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0072] Currently, judging from market trends, the application of battery devices is becoming increasingly widespread. Battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery device applications, market demand is also constantly increasing.

[0073] A battery device typically comprises multiple battery cells. Each battery cell includes a casing and electrode assemblies. The casing houses the electrode assemblies, which are the components within the battery cell where electrochemical reactions occur. Electrode assemblies can be manufactured using a winding or lamination process, consisting of a positive electrode, a negative electrode, and a separator. For electrode assemblies manufactured using a winding process, a winding device is typically used to wind the substrate to form the electrode assembly. Specifically, the winding device includes a support frame, a central shaft, a turntable, and a needle winding assembly. The central shaft is rotatably mounted on the support frame, the turntable is coaxially connected to the central shaft, and the needle winding assembly is mounted on the support frame and used to wind the substrate. The turntable and the central shaft can rotate synchronously, driving the needle winding assembly to rotate around the central shaft, thereby conveying the wound substrate to the corresponding workstation and completing the corresponding processes at that workstation until the electrode assembly is formed.

[0074] In related technologies, the support frame, central shaft, and turntable are all assembled from multiple components. To improve the quality of the electrode assembly, after the winding device is assembled, precision adjustment is required. This includes adjusting parameters such as the coaxiality and parallelism of the central shaft, and the coaxiality between the turntable and the central shaft, to improve the working accuracy of the winding device. However, since the support frame, central shaft, and turntable are all assembled from multiple components, the assembly accuracy of each component affects the precision adjustment of the winding device. The more components there are, the more difficult the precision adjustment becomes, which is detrimental to improving the reliability of the winding device.

[0075] Based on the above considerations, in order to reduce the difficulty of precision debugging of the winding device, the support frame, central shaft and turntable in the winding equipment provided in this application are all integrally formed components. This not only effectively improves the structural accuracy of the support frame, central shaft and turntable, but also, after the central shaft and turntable are coaxially connected and installed on the support frame, they can form the main body of the winding device, effectively reducing the number of parts of the winding device, thereby effectively reducing the difficulty of precision debugging of the winding device and effectively improving the reliability of the winding device.

[0076] The winding device provided in this application embodiment is used to process and form electrode components in a battery cell. A battery cell is the smallest unit in a battery device for storing electrical energy. The battery device is suitable for electrical equipment that uses the battery device as a power source or for various energy storage systems that use the battery device as an energy storage element.

[0077] Electrical equipment can include, but is not limited to, mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, vehicles, ships, and spacecraft, such as airplanes, rockets, space shuttles, and spacecraft.

[0078] The technical solutions provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0079] Firstly, please refer to the following: Figure 2 and Figure 4 This application provides a winding device 100, including a support frame 110, a central rotating shaft 120, a turntable 130, and a winding needle assembly 140. The support frame 110 is used to be mounted on the frame 200 of a battery manufacturing equipment. The central rotating shaft 120 is rotatably mounted on the support frame 110. The turntable 130 is disposed on the central rotating shaft 120 and coaxially connected to the central rotating shaft 120. The winding needle assembly 140 is mounted on the turntable 130. The support frame 110, the central rotating shaft 120, and the turntable 130 are all integrally formed components.

[0080] The frame 200 is the supporting structure of the battery manufacturing equipment, providing an installation environment for mechanisms such as the winding device 100, the unloading mechanism 300, and the forming mechanism 400. The frame 200 can be a one-piece molded component, meaning it is manufactured using a one-piece molding process, which can be, but is not limited to, die casting or casting. Alternatively, the frame 200 can consist of multiple parts, each individually molded and then connected to form a whole. The material of the frame 200 can be, but is not limited to, aluminum alloy, steel, iron, and copper.

[0081] The support frame 110 provides an installation environment for components such as the central shaft 120 and turntable 130 in the winding device 100. The support frame 110 is mounted on the frame 200 of the battery manufacturing equipment. The connection between the support frame 110 and the frame 200 can be, but is not limited to, fastening, welding, bonding, or clamping. The support frame 110 is a one-piece molded component, meaning it is manufactured using a one-piece molding process, which can be, but is not limited to, die casting or casting. The material of the support frame 110 can be, but is not limited to, aluminum alloy, steel, iron, and copper.

[0082] The central pivot 120 supports the turntable 130, enabling the turntable 130 to rotate on the support frame 110. The central pivot 120 is a one-piece molded component, meaning it is manufactured using a one-piece molding process, which can be, but is not limited to, die casting or casting. The material of the central pivot 120 can be, but is not limited to, aluminum alloy, steel, iron, copper, etc.

[0083] In some embodiments, the support frame 110 has a mounting cavity 113, a second shaft hole 114, and a third shaft hole 115. The second shaft hole 114 and the third shaft hole 115 are respectively disposed on opposite sides of the mounting cavity 113. The central rotating shaft 120 and the turntable 130 are both disposed in the mounting cavity 113. One end of the central rotating shaft 120 is rotatably mounted in the second shaft hole 114, and the other end of the central rotating shaft 120 is rotatably mounted in the third shaft hole 115.

[0084] As an example, the winding device 100 also includes a first bearing and a second bearing. The first bearing is sleeved on one end of the central rotating shaft 120 and fixed in the second shaft hole 114, and the second bearing is sleeved on the other end of the central rotating shaft 120 and fixed in the third shaft hole 115.

[0085] The turntable 130 provides an installation environment for the needle coil assembly 140 and is coaxially connected to the central rotating shaft 120. The turntable 130 may have winding stations, adhesive application stations, finishing stations, and unloading stations. By rotating the turntable 130, the substrate is transported to the corresponding station and the corresponding process is completed at that station until the electrode assembly is formed. The turntable 130 is a one-piece molded component, meaning it is manufactured using a one-piece molding process. This molding process can be, but is not limited to, die casting or casting. The material of the turntable 130 can be, but is not limited to, aluminum alloy, steel, iron, copper, etc.

[0086] In some embodiments, the turntable 130 has a first shaft hole, and the central rotating shaft 120 passes through the first shaft hole and is fixedly connected to the turntable 130.

[0087] In some embodiments, the winding device 100 includes a first driver 180 for driving the turntable 130 to rotate. As an example, the first driver 180 may be a motor. As an example, the first driver 180 is mounted on a support frame 110.

[0088] In some embodiments, the turntable 130 includes a first disc body 131, a second disc body 132, and a connector 133. The connector 133 is connected between the first disc body 131 and the second disc body 132. A portion of the needle winding assembly 140 is mounted between the first disc body 131 and the second disc body 132, and another portion of the needle winding assembly 140 protrudes from the side of the first disc body 131 opposite to the second disc body 132 in a direction away from the second disc body 132. As an example, a first shaft hole passes through the first disc body 131 and the second disc body 132.

[0089] The winding assembly refers to the mechanism in the winding device 100 used to wind a substrate to form an electrode assembly.

[0090] In some embodiments, the winding needle assembly 140 includes a winding needle 141 and a drive shaft 142. The drive shaft 142 is rotatably connected between a first disc 131 and a second disc 132, and the winding needle 141 is connected to the end of the drive shaft 142 away from the second disc 132. The winding needle 141 refers to a component in the winding assembly used for winding a substrate. Depending on the desired shape of the electrode assembly, the winding needle 141 can be cylindrical to form a cylindrical electrode assembly, or it can be prismatic to form a prismatic electrode assembly. Understandably, the winding needle 141 can also be other shapes. As an example, the winding needle assembly 140 further includes a second driver for driving the drive shaft 142 to rotate, thereby rotating the winding needle 141. As an example, the second driver can be a motor. Understandably, the drive shaft 142 is arranged parallel to the central rotating shaft 120.

[0091] In some embodiments, the needle winding assembly 140 further includes a rotating bracket 143, which is fixedly sleeved on the central rotating shaft 120. The needle winding assembly 140 includes a plurality of needles 141 and a plurality of drive shafts 142, with each needle 141 corresponding to one of the drive shafts 142. The needles 141 are rotatably mounted on the rotating bracket 143 to support the plurality of needles 141, thereby effectively reducing the load borne by the needles 141 and the drive shafts 142. Understandably, the number of needles 141 and the number of drive shafts 142 are equivalent to the number of workstations on the turntable 130.

[0092] The support frame 110, central rotating shaft 120, and turntable 130 in the winding device 100 provided in this application embodiment are all integrally formed components. This not only effectively improves the structural accuracy of the support frame 110, central rotating shaft 120, and turntable 130, but also, by coaxially connecting the central rotating shaft 120 and turntable 130 and installing them onto the support frame 110, the main body of the winding device 100 can be formed. This effectively reduces the number of parts in the winding device 100, thereby effectively reducing the difficulty of precision debugging of the winding device 100 and effectively improving the reliability of the winding device 100.

[0093] In some embodiments of this application, please refer to Figure 2 The winding device 100 also includes a position adjustment mechanism 150, which is used to adjust the position of the support frame 110 relative to the frame 200.

[0094] The winding device 100 has a first direction, a second direction, and a third direction, which are arranged perpendicularly to each other, i.e., the first direction is perpendicular to the second direction, and the third direction is perpendicular to the first and second directions. As an example, the first direction can be the height direction of the winding device 100 (e.g., the direction of height). Figure 2 The second direction can be the width direction of the winding device 100 (as shown in the Z direction). Figure 2 The Y direction shown can be the length direction of the winding device 100 (e.g., the Y direction). Figure 2 The X direction shown is the third direction, which is parallel to the axis of the central rotation axis 120.

[0095] In some embodiments, the position adjustment mechanism 150 can be used to adjust the position of the support frame 110 relative to the frame 200 along at least one of the first direction, the second direction, and the third direction.

[0096] By adopting the above technical solution, the position of the support frame 110 can be adjusted by operating the position adjustment mechanism 150, thereby adjusting the position of the main body of the winding device 100. The operation is simple and convenient, further reducing the difficulty of precision debugging of the winding device 100, and thus further improving the reliability of the winding device 100.

[0097] In some embodiments of this application, please refer to Figure 2 The position adjustment mechanism 150 includes a first adjustment component 151, which is used to adjust the position of the support frame 110 relative to the frame 200 along a first direction.

[0098] The first adjustment component 151 is used to adjust the position of the support frame 110 relative to the frame 200 along a first direction. In some embodiments, the first direction is the height direction of the winding device 100 (e.g., the height direction of the winding device 100). Figure 2 (Z direction shown). The first adjustment component 151 can be, but is not limited to, a push rod assembly, a ball screw assembly, a gear and rack assembly, etc.

[0099] By adopting the above technical solution, the position of the support frame 110 can be adjusted along the first direction by operating the first adjustment component 151, so as to adjust the position of the main body of the winding device 100 along the first direction. The operation is simple and convenient, further reducing the difficulty of precision debugging of the winding device 100, thereby further improving the reliability of the winding device 100.

[0100] In some embodiments of this application, please refer to Figure 2 The first adjustment component 151 includes a first adjustment member 1511, the first adjustment member 1511 includes a first threaded portion 15111, the support frame 110 has a first threaded hole 111, the first threaded hole 111 passes through the support frame 110 in a first direction, the first threaded portion 15111 is threaded to the first threaded hole 111 and passes through the first threaded hole 111 to abut against the frame 200.

[0101] In some embodiments, the first direction is the height direction of the winding device 100 (e.g., Figure 2 As shown in the Z direction, the first adjusting member 1511 can be rotated in different directions to cause the support frame 110 to reciprocate along the first direction, thereby adjusting the position of the support frame 110 along the first direction. For example, the first adjusting member 1511 can be rotated clockwise to gradually move the support frame 110 closer to the frame 200 along the first direction, and it can also be rotated counterclockwise to gradually move the support frame 110 away from the frame 200 along the first direction, thus adjusting the position of the support frame 110 along the first direction.

[0102] In some embodiments, please refer to Figure 5 The first adjustment component 151 also includes a first anti-loosening structure 1513, which is used to restrict the rotation of the first threaded portion 15111 after the support frame 110 is adjusted to a preset position along the first direction, so as to improve the situation where the position of the support frame 110 is offset along the first direction.

[0103] As an example, the first anti-loosening structure 1513 includes a first anti-loosening nut 15131 and a second anti-loosening nut 15132. Both the first anti-loosening nut 15131 and the second anti-loosening nut 15132 are threadedly connected to the first threaded portion 15111. After the support frame 110 is adjusted to a preset position along the first direction, the second anti-loosening nut 15132 is rotated so that the second anti-loosening nut 15132 is pressed tightly against the surface of the support frame 110 facing away from the frame 200. Then the first anti-loosening nut 15131 is rotated so that the first anti-loosening nut 15131 is pressed tightly against the surface of the second anti-loosening nut 15132 facing away from the frame 200. In this way, the risk of the first threaded portion 15111 loosening in a vibration environment can be effectively reduced, thereby improving the situation where the position of the support frame 110 shifts along the first direction.

[0104] By adopting the above technical solution, the support frame 110 can be moved relative to the frame 200 along the first direction by rotating the first adjusting member 1511, so as to adjust the position of the support frame 110 along the first direction, thereby adjusting the position of the main body of the winding device 100 along the first direction. The operation is simple and convenient, further reducing the difficulty of precision debugging of the winding device 100 and further improving the reliability of the winding device 100.

[0105] Please refer to some embodiments of this application as well. Figure 2 and Figure 6 The first adjustment assembly 151 further includes a first locking attachment 1512 for locking the support frame 110 to the frame 200 to restrict the movement of the support frame 110 relative to the frame 200 in a first direction.

[0106] Understandably, the first locking accessory 1512 is used to lock the support frame 110 onto the frame 200 after the support frame 110 has been adjusted to a preset position along the first direction, so as to restrict the movement of the support frame 110 relative to the frame 200 along the first direction. The first locking accessory 1512 can be a bolt, rivet, etc.

[0107] By adopting the above technical solution, the first locking attachment 1512 can lock the support frame 110 onto the frame 200 after the position adjustment operation of the support frame 110 along the first direction is completed, so as to restrict the movement of the support frame 110 relative to the frame 200 along the first direction, effectively improving the situation where the relative position of the support frame 110 and the frame 200 shifts during the operation of the winding device 100, thereby further improving the reliability of the winding device 100.

[0108] Please refer to some embodiments of this application as well. Figure 2 and Figure 6The support frame 110 has a first through hole 112, which penetrates the support frame 110 along a first direction. The first locking accessory 1512 includes a first pressing part 15121 and a first connecting part 15122. The first connecting part 15122 passes through the first through hole 112 and is connected to the frame 200. The first pressing part 15121 presses against the support frame 110 to restrict the support frame 110 from moving relative to the frame 200 along the first direction.

[0109] Understandably, when the first locking attachment 1512 is in the locked state, the first connecting part 15122 is connected to the frame 200, and the first pressing part 15121 presses against the surface of the support frame 110 facing away from the frame 200 to restrict the support frame 110 from moving relative to the frame 200 in the first direction.

[0110] In some embodiments, the frame 200 has a fourth threaded hole, and the first connecting part 15122 is threaded into the fourth threaded hole. The first locking accessory 1512 can be rotated so that the first connecting part 15122 engages with the thread of the fourth threaded hole until the first pressing part 15121 presses tightly against the surface of the support frame 110 facing away from the frame 200, so as to restrict the support frame 110 from moving relative to the frame 200 in the first direction.

[0111] By adopting the above technical solution, the movement of the support frame 110 relative to the frame 200 in the first direction is effectively restricted, thereby further improving the reliability of the winding device 100.

[0112] In some embodiments of this application, please refer to Figure 2 The number of first adjustment components 151 is multiple, at least one first adjustment component 151 is disposed on one side of the support frame 110 along the second direction, at least another first adjustment component 151 is disposed on the other side of the support frame 110 along the second direction, and at least another first adjustment component 151 is disposed on one side of the support frame 110 along the third direction.

[0113] Understandably, the number of the first adjustment components 151 can be determined according to the actual application needs, specifically 2, 3, 6, 8, etc.

[0114] In some embodiments, at least two first adjustment components 151 are disposed on one side of the support frame 110 along the second direction and arranged sequentially along the first direction, at least two other first adjustment components 151 are disposed on the other side of the support frame 110 along the second direction and arranged sequentially along the first direction, and at least two more first adjustment components 151 are disposed on one side of the support frame 110 along the third direction and arranged sequentially along the second direction.

[0115] By adopting the above technical solution, the positions of multiple parts of the support frame 110 can be adjusted along the first direction, which effectively improves the consistency of the relative positions of each part of the support frame 110 and the frame 200, thereby effectively improving the debugging accuracy of the winding device 100 and further improving the reliability of the winding device 100.

[0116] In some embodiments of this application, please refer to Figure 2 The position adjustment mechanism 150 also includes a second adjustment component 152, which is used to adjust the position of the support frame 110 relative to the frame 200 along a second direction.

[0117] The second adjustment component 152 is used to adjust the position of the support frame 110 relative to the frame 200 along a second direction. In some embodiments, the first direction is the height direction of the winding device 100 (e.g., Figure 2 The Z direction shown is the first direction, and the second direction is the width direction of the winding device 100 (e.g., the Z direction). Figure 2 (Y direction shown). The second adjustment component 152 can be, but is not limited to, a push rod assembly, a ball screw assembly, a gear and rack assembly, etc.

[0118] By adopting the above technical solution, the position of the support frame 110 can be adjusted along the second direction by operating the second adjustment component 152, so as to adjust the position of the main body of the winding device 100 along the second direction. The operation is simple and convenient, further reducing the difficulty of precision debugging of the winding device 100, thereby further improving the reliability of the winding device 100.

[0119] Please refer to some embodiments of this application as well. Figure 2 , Figure 7 and Figure 8 The second adjustment component 152 includes a first support 1521 and a second adjustment member 1522. The first support 1521 is mounted on the frame 200 and has a second threaded hole 15211. The second threaded hole 15211 passes through the first support 1521 in a second direction. The second adjustment member 1522 includes a second threaded portion 15221. The second threaded portion 15221 is threaded to the second threaded hole 15211 and passes through the second threaded hole 15211 to abut against the support frame 110.

[0120] The first support 1521 is used to support the second adjusting member 1522 and provide an installation environment for the second adjusting member 1522. In some embodiments, the first support 1521 is fixedly connected to the frame 200, and the connection method between the first support 1521 and the frame 200 can be, but is not limited to, welding, bonding, fastening, etc.

[0121] Understandably, the second adjusting member 1522 can be rotated to push the support frame 110 to reciprocate along the second direction, so as to adjust the position of the support frame 110 along the second direction.

[0122] In some embodiments, the second adjustment assembly 152 further includes a second anti-loosening structure 1523, which is used to restrict the rotation of the second threaded portion 15221 after the support frame 110 is adjusted to a preset position along the second direction, so as to improve the situation where the position of the support frame 110 is offset along the second direction.

[0123] As an example, the second anti-loosening structure 1523 includes a third anti-loosening nut 15231 and a fourth anti-loosening nut 15232. Both the third anti-loosening nut 15231 and the fourth anti-loosening nut 15232 are threadedly connected to the second threaded portion 15221. After the support frame 110 is adjusted to a preset position along the second direction, the fourth anti-loosening nut 15232 is rotated so that the fourth anti-loosening nut 15232 is pressed tightly against the surface of the first support 1521 facing away from the support frame 110. Then, the third anti-loosening nut 15231 is rotated so that the third anti-loosening nut 15231 is pressed tightly against the surface of the fourth anti-loosening nut 15232 facing away from the support frame 110. In this way, the risk of the second threaded portion 15221 loosening in a vibration environment can be effectively reduced, thereby improving the situation where the position of the support frame 110 shifts along the second direction.

[0124] By adopting the above technical solution, the support frame 110 can be moved relative to the frame 200 in the second direction by rotating the second adjusting member 1522, so as to adjust the position of the support frame 110 in the second direction, thereby adjusting the position of the main body of the winding device 100 in the second direction. The operation is simple and convenient, further reducing the difficulty of precision debugging of the winding device 100 and further improving the reliability of the winding device 100.

[0125] In some embodiments of this application, please refer to Figure 2 The number of second adjustment components 152 is multiple, at least one second adjustment component 152 is disposed on one side of the support frame 110 along the second direction, and at least another second adjustment component 152 is disposed on the other side of the support frame 110 along the second direction.

[0126] Understandably, the number of the second adjustment components 152 can be determined according to the actual application needs, specifically 2, 3, 6, 8, etc.

[0127] In some embodiments, the first direction is the height direction of the winding device 100 (e.g., Figure 2 The Z direction shown is the first direction, and the second direction is the width direction of the winding device 100 (e.g., the Z direction). Figure 2(As shown in the Y direction), the second adjusting member 1522 located on one side of the support frame 110 along the second direction can be rotated to push the support frame 110 along the second direction to gradually approach the second adjusting member 1522 located on the other side of the support frame 110 along the second direction. After the support frame 110 is adjusted to a preset position along the second direction, the respective second adjusting members 1522 located on opposite sides of the support frame 110 along the second direction can be tightened so that the respective second adjusting members 1522 located on opposite sides of the support frame 110 along the second direction cooperate to clamp and fix the support frame 110.

[0128] By adopting the above technical solution, the position of the support frame 110 along the second direction can be adjusted by operating the second adjustment components 152 located on both sides of the support frame 110 along the second direction, thereby adjusting the position of the main body of the winding device 100 along the second direction. The operation is simple and convenient, further reducing the difficulty of precision debugging of the winding device 100 and further improving the reliability of the winding device 100.

Figure 2 The Y direction (as shown) and the third direction are the length directions of the winding device 100 (e.g., the Y direction). Figure 2 (The X direction is shown). The third adjustment component 153 can be, but is not limited to, a push rod assembly, a ball screw assembly, a gear and rack assembly, etc.

The operation is simple and convenient, further reducing the difficulty of precision debugging of the winding device 100, thereby further improving the reliability of the winding device 100.

[0132] Please refer to some embodiments of this application as well. Figure 2 , Figure 9 , Figure 10 and Figure 11The third adjustment component 153 includes a second support 1531 and a third adjustment member 1532. The second support 1531 is mounted on the frame 200 and has a third threaded hole 15311. The third threaded hole 15311 passes through the second support 1531 in a third direction. The third adjustment member 1532 includes a third threaded part 15321. The third threaded part 15321 is threaded to the third threaded hole 15311 and passes through the third threaded hole 15311 to abut against the support frame 110.

[0133] The second support 1531 is used to support the third adjusting member 1532 and provide an installation environment for the third adjusting member 1532. In some embodiments, the second support 1531 is fixedly connected to the frame 200, and the connection method between the second support 1531 and the frame 200 can be, but is not limited to, welding, bonding, fastening, etc.

[0134] Understandably, the third adjusting member 1532 can be rotated to push the support frame 110 to reciprocate along a third direction, thereby adjusting the position of the support frame 110 along the third direction.

[0135] In some embodiments, the third adjustment component 153 further includes a third anti-loosening structure 1534, which is used to restrict the rotation of the third threaded portion 15321 after the support frame 110 is adjusted to a preset position along the third direction, so as to improve the situation where the position of the support frame 110 is offset along the third direction.

[0136] As an example, the third anti-loosening structure 1534 includes a fifth anti-loosening nut 15341 and a sixth anti-loosening nut 15342. Both the fifth anti-loosening nut 15341 and the sixth anti-loosening nut 15342 are threadedly connected to the third threaded portion 15321. After the support frame 110 is adjusted to a preset position along the third direction, the sixth anti-loosening nut 15342 is rotated so that the sixth anti-loosening nut 15342 is pressed tightly against the surface of the second support 1531 facing away from the support frame 110. Then, the fifth anti-loosening nut 15341 is rotated so that the fifth anti-loosening nut 15341 is pressed tightly against the surface of the sixth anti-loosening nut 15342 facing away from the support frame 110. In this way, the risk of the third threaded portion 15321 loosening in a vibration environment can be effectively reduced, thereby improving the situation where the position of the support frame 110 shifts along the third direction.

[0137] By adopting the above technical solution, the support frame 110 can be moved relative to the frame 200 in a third direction by rotating the third adjusting member 1532, so as to adjust the position of the support frame 110 in the third direction, thereby adjusting the position of the main body of the winding device 100 in the third direction. The operation is simple and convenient, further reducing the difficulty of precision debugging of the winding device 100 and further improving the reliability of the winding device 100.

[0138] Please refer to some embodiments of this application as well. Figure 2 and Figure 11 The third adjustment assembly 153 also includes a second locking attachment 1533 for locking the support frame 110 to the frame 200 to restrict the movement of the support frame 110 relative to the frame 200 in a third direction.

[0139] Understandably, the second locking accessory 1533 is used to lock the support frame 110 onto the frame 200 after the support frame 110 has been adjusted to a preset position along a third direction, thereby restricting the movement of the support frame 110 relative to the frame 200 along a third direction. The second locking accessory 1533 can be a bolt, rivet, etc.

[0140] By adopting the above technical solution, the second locking attachment 1533 can lock the support frame 110 onto the frame 200 after the position adjustment operation of the support frame 110 in the third direction is completed, thereby restricting the movement of the support frame 110 relative to the frame 200 in the third direction. This effectively improves the situation where the relative position of the support frame 110 and the frame 200 shifts during the operation of the winding device 100, thereby further improving the reliability of the winding device 100.

[0141] Please refer to some embodiments of this application as well. Figure 2 and Figure 11 The second support 1531 has a second through hole 15312, which passes through the second support 1531 in a third direction. The second locking accessory 1533 includes a second pressing part 15331 and a second connecting part 15332. The second connecting part 15332 passes through the second through hole 15312 and is connected to the support frame 110. The second pressing part 15331 presses against the second support 1531 to restrict the movement of the support frame 110 relative to the frame 200 in a third direction.

[0142] Understandably, when the second lock attachment 1533 is in the locked state, the second connecting part 15332 is connected to the support frame 110, and the second pressing part 15331 presses against the surface of the second support 1531 facing away from the support frame 110, so as to restrict the support frame 110 from moving relative to the frame 200 in a third direction.

[0143] In some embodiments, the support frame 110 has a fifth threaded hole, and the second connecting part 15332 is threaded into the fifth threaded hole. The second locking attachment 1533 can be rotated so that the second connecting part 15332 engages with the thread of the fifth threaded hole until the second pressing part 15331 presses tightly against the surface of the second support 1531 facing away from the support frame 110, so as to restrict the support frame 110 from moving relative to the frame 200 in a third direction.

[0144] By adopting the above technical solution, the movement of the support frame 110 relative to the frame 200 in a third direction is effectively restricted, thereby further improving the reliability of the winding device 100.

[0145] In some embodiments of this application, please refer to Figure 2 The number of third adjustment components 153 is multiple, and the multiple third adjustment components 153 are disposed on one side of the support frame 110 along the third direction and separated along the second direction.

[0146] Understandably, the number of the third adjustment components 153 can be determined according to the actual application needs, specifically 2, 3, 6, 8, etc.

[0147] In some embodiments, the first direction is the height direction of the winding device 100 (e.g., Figure 2 The Z direction shown is the first direction, and the second direction is the width direction of the winding device 100 (e.g., the Z direction). Figure 2 The Y direction (as shown) and the third direction are the length directions of the winding device 100 (e.g., the Y direction). Figure 2 (As shown in the X direction), the frame 200 includes a frame body 210 and a support plate 220. The support frame 110 is mounted on the frame body 210. The support plate 220 is used to prevent the support frame 110 from moving along a third direction. A plurality of third adjustment components 153 are disposed on the side of the support frame 110 facing away from the support plate 220 along the third direction. The third adjustment member 1532 in each of the third adjustment components 153 can be rotated to push the support frame 110 gradually closer to the support plate 220 along the third direction until the support frame 110 is pressed tightly against the support plate 220.

[0148] By adopting the above technical solution, the position of each part of the support frame 110 along the second direction can be adjusted along the third direction, which effectively improves the consistency of the relative position of each part of the support frame 110 along the second direction with the frame 200, thereby effectively improving the debugging accuracy of the winding device 100 and further improving the reliability of the winding device 100.

[0149] In some embodiments of this application, please refer to Figure 3 The winding device 100 also includes a support wheel 160, which is rotatably mounted on the support frame 110 and is used to support the turntable 130.

[0150] Understandably, along the height direction of the winding device 100, the support wheel 160 is disposed below the turntable 130, the rotation axis of the support wheel 160 is parallel to the rotation axis of the turntable 130, and the outer peripheral surface of the support wheel 160 is in contact with the outer peripheral surface of the turntable 130 to support the turntable 130 and rotate synchronously with the turntable 130.

[0151] By adopting the above technical solution, the load on the central rotating shaft 120 can be effectively reduced, the risk of deformation of the central rotating shaft 120 can be effectively reduced, and the reliability of the winding device 100 can be further improved.

[0152] In some embodiments of this application, please refer to Figure 3 The support wheel 160 is used to support the first disc 131.

[0153] In some embodiments, the needle winding assembly 140 includes a needle winding 141 and a drive shaft 142, the drive shaft 142 being rotatably connected between a first disc 131 and a second disc 132, and the needle winding 141 being connected to the end of the drive shaft 142 away from the second disc 132. In other words, in the assembly formed by the needle winding assembly 140 and the turntable 130, the first disc 131 is located approximately at the center of the assembly.

[0154] By adopting the above technical solution, the support wheel 160 can support the middle part of the whole consisting of the central rotating shaft 120, the turntable 130 and the winding needle assembly 140, thereby effectively reducing the load on the middle part of the central rotating shaft 120, further reducing the risk of deformation of the central rotating shaft 120, and thus further improving the reliability of the winding device 100.

[0155] In some embodiments of this application, there are two support wheels 160, which are respectively located on opposite sides of the central axis of the central rotating shaft 120.

[0156] By adopting the above technical solution, the load borne by the middle part of the central rotating shaft 120 is further reduced, the risk of deformation of the central rotating shaft 120 is further reduced, and the reliability of the winding device 100 is further improved.

[0157] Of course, in other embodiments, the number of support wheels 160 may be more than two.

[0158] In some embodiments of this application, the turntable 130 has a first shaft hole, and the central rotating shaft 120 passes through the first shaft hole and is interference-fitted with the turntable 130.

[0159] In some embodiments, the central rotating shaft 120 and the turntable 130 are assembled using a heat fitting process. Specifically, the turntable 130 is heated to expand, and correspondingly, the diameter of the first shaft hole increases so that the diameter of the first shaft hole is slightly larger than the outer diameter of the central rotating shaft 120. At this time, the central rotating shaft 120 can be inserted into the first shaft hole. Then, the turntable 130 is cooled to shrink, and correspondingly, the diameter of the first shaft hole decreases so that the diameter of the first shaft hole is smaller than the outer diameter of the central rotating shaft 120, thereby making the central rotating shaft 120 and the turntable 130 interference fit.

[0160] By adopting the above technical solution, it is not only convenient to assemble the turntable 130 and the central shaft 120, but also to effectively improve the stability of the connection between the turntable 130 and the central shaft 120.

[0161] In some embodiments of this application, a rotation limiting structure is provided between the turntable 130 and the central rotating shaft 120. The rotation limiting structure is used to restrict the relative rotation of the turntable 130 and the central rotating shaft 120.

[0162] By adopting the above technical solution, the relative rotation between the turntable 130 and the central shaft 120 is effectively restricted, thereby further improving the stability of the connection between the turntable 130 and the central shaft 120.
