Description

Technical Field

[0001] This utility model relates to the technical field of motor rotor winding equipment, specifically to a tensioning mechanism and a winding device including the same. Background Technology

[0002] The core function of automatic winding equipment is to automatically wind conductors (such as enameled wire or copper foil) onto a winding die according to preset parameters. The feeding end of such automatic winding equipment typically includes a tension control mechanism to ensure the stability of the conductor tension. Currently, the tension control mechanism of winding equipment usually consists of multiple tensioning rollers of different sizes arranged in a specific layout. The conductor is wound onto different tensioning rollers in a certain order to adjust the conductor tension.

[0003] However, this method has several problems. First, its applicability is limited. Since the tensioning wheel is in a relatively fixed state, the tension control mechanism has a limited range of tension adjustment. Once the wire material or the wire thickness is changed, the tensioning wheel needs to be changed according to the current wire. Second, there is a risk of breakage. Since most current tension adjustments tend to keep the wire under tension, the automatic winding equipment will over-pull the wire at the moment of startup, which may cause the wire to break.

[0004] Based on this, Chinese utility model patent document (CN218733756U) discloses a tensioning mechanism for a winding machine, which uses a connecting component and a reset component connected to the rotating shaft to limit the rotation of the shaft, and adjusts the position of the connecting plate to change the position of the movable tensioning wheel. However, the technical solution disclosed in this patent involves many auxiliary structures, which occupy a large amount of space. Utility Model Content

[0005] This invention provides a tensioning mechanism and a winding device including the same, to solve the problem of low wire tension adjustment range in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention provides a tensioning mechanism and a winding device, wherein the tensioning mechanism includes a base, an elastic adjustment component, and a mounting base.

[0007] The base is provided with a plurality of first mounting positions for fixing the first winding wheel; the elastic adjustment component is located on the base and is provided with one or more guide bars extending along a first direction and elastic members sleeved on the guide bars, wherein the guide bars are provided with first limiting seats and second limiting seats at intervals at both ends along the first direction; the mounting seat is sleeved on the guide bars and is located between two adjacent first limiting seats and second limiting seats along the first direction, wherein the mounting seat is used to fix the second winding wheel.

[0008] The beneficial effects of the technical solution provided by this utility model compared to the prior art are as follows:

[0009] By adding an elastic adjustment component and a mounting base that cooperates with the elastic adjustment component, when the second winding wheel is wound with an overly tight wire, the elastic element can drive the mounting base to contract along the guide bar, thereby adaptively loosening the wire and avoiding breakage caused by excessive wire tightness. The elastic adjustment component is located on the base, requiring minimal space, and the space utilized by the elastic element, which is fitted onto the guide bar extending in the first direction, is the space between the tensioning wheel (similar to the first and second winding wheels mentioned above) and the base. This minimizes the impact on the original winding equipment and allows for a more compact arrangement of the components on the base.

[0010] Furthermore, by using the elastic element to adaptively adjust the position of the mounting base connected to it, that is, to adjust the height of the mounting base, when changing wires of different diameters or materials, it is not necessary to change the arrangement of the first winding wheel. It can also quickly adapt to tension changes and provide a stable tension output for the winding equipment, reducing the impact of tension fluctuations on winding quality.

[0011] In some embodiments, the base is further provided with an inner cavity, wherein a support seat and a support rod embedded in the support seat are fixedly disposed in the inner cavity.

[0012] Compared to the current base which is simply a single plate, the above-mentioned technical solution features an internal cavity, making it a box-type structure. This increases the structural strength of the base and protects the mounting components inside, preventing dust and debris from entering. Furthermore, the inclusion of a support base and support rod for connection to the entire machine allows the tensioning mechanism to be mounted externally on the winding equipment, utilizing the space above it.

[0013] In some embodiments, the support base is provided with a plurality of first locking holes spaced apart along the first direction, wherein the base is provided with second locking holes corresponding to the first locking holes.

[0014] By adopting the above technical solution, the connection area between the base and the support can be increased by connecting multiple first locking holes and second locking holes, thereby making the center of gravity of the base more biased towards the support rod.

[0015] In some embodiments, the base further includes a mounting groove extending along a first direction, wherein a magnetic powder brake penetrating the mounting groove is embedded within the base. Further, the magnetic powder brake is used to connect to a third winding reel.

[0016] Using the above technical solution, the magnetic powder brake is a component composed of a rotor, stator, magnetic powder, coil, etc. The rotor of the magnetic powder brake is connected to the third winding wheel, so that when the magnetic powder brake is energized, the magnetic powder can form a magnetic flux under the action of the electromagnetic field to adjust the rotational resistance of the third winding wheel. Thus, when the current of the magnetic powder brake is adjusted, the tension of the third winding wheel can be changed accordingly.

[0017] In some embodiments, the base is further provided with a first through groove parallel to the guide bar, wherein the first limiting seat is fixed in the first through groove. By adopting the above technical solution and providing a first through groove to install the first limiting seat, the tension adjustment range of the elastic adjustment component can be further improved.

[0018] In some embodiments, the base further includes a second mounting position located at the bottom of the guide bar and used to fix the second limiting seat. By employing the above technical solution, the second limiting seat is fixedly installed so that when adjusting the tension adjustment range of the elastic adjustment component, only the first limiting seat needs to be adjusted.

[0019] In some embodiments, the elastic adjustment assembly further includes buffer pads, which are respectively sleeved on the guide strips and located between the second limiting seat and the mounting seat along the first direction. Using the above technical solution, the buffer pads can effectively buffer the collision between the mounting seat and the second limiting seat.

[0020] In some embodiments, the first winding wheel further includes an inlet winding wheel and an outlet winding wheel, wherein the conductor is wound sequentially along the inlet winding wheel to the third winding wheel, the second winding wheel, and the outlet winding wheel.

[0021] In some embodiments, this application also provides a winding device, including the above-described tensioning mechanism and a frame connected to a support rod of the tensioning mechanism. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] For ease of subsequent description, this application will first combine [the following descriptions] before describing the specific structure of the tensioning mechanism. Figure 1 Define a first direction (Z). The first direction is the height direction of the tensioning mechanism when it is normally placed, such as the Z direction.

[0035] See Figures 1 to 2 As shown, Figure 1 This application provides a three-dimensional structural schematic diagram of an embodiment of a tensioning mechanism. Figure 1 ; Figure 2 A front view of an embodiment of a tensioning mechanism provided in this application is shown, wherein, Figure 2 The black lines represent the conductors that are sequentially wound around the inlet winding wheel 120, the first winding wheel 12, the second winding wheel 31, the third winding wheel 140, and the outlet winding wheel 121.

[0036] In some embodiments, the tensioning mechanism includes a base 10, an elastic adjustment assembly 20, and a mounting base 30. The base 10 is provided with a plurality of first mounting positions 11 for fixing the first winding wheel 12; the elastic adjustment assembly 20 is located on the base 10 and is provided with one or more guide bars 21 extending along a first direction and elastic members 22 sleeved on the guide bars 21, wherein the guide bars 21 are provided with first limiting seats 23 and second limiting seats 24 at intervals at both ends along the first direction; the mounting base 30 is sleeved on the guide bars 21 and is located between two adjacent first limiting seats 23 and second limiting seats 24 along the first direction, wherein the mounting base 30 is used to fix the second winding wheel 31.

[0037] In this embodiment, by adding an elastic adjustment component 20 and a mounting base 30 that cooperates with the elastic adjustment component 20, when the second winding wheel 31 winds an excessively tight wire, the elastic element 22 can drive the mounting base 30 to contract along the guide bar 21, thereby adaptively loosening the wire to avoid breakage caused by excessive wire tightness. Exemplarily, the inlet end of the tensioning mechanism is provided with a feeding mechanism (e.g., a device that continuously straightens and transports enameled wire raw materials), such as... Figure 2 As shown, a first winding wheel 12 with a smaller inner diameter is used as the inlet winding wheel 120, according to... Figure 2 The winding proceeds in the direction indicated by the arrow to the outlet winding reel 121. This application does not limit the winding sequence. Furthermore, this application does not limit the specifications of the first winding reel 12 or the winding arrangement; for example, the first winding reel 12 can be... Figure 2 The various diameter lengths shown can all be adapted to different application scenarios.

[0038] Combination Figure 3 As shown, Figure 3 A side view of an embodiment of a tensioning mechanism provided in this application is shown. The elastic adjustment assembly 20 is located on the base 10, requiring minimal space, and the elastic element 22 is sleeved on the guide strip 21 extending along the first direction, utilizing the space between the first tensioning wheel and the base 10. Figure 3 As shown, it occupies less space in the original winding equipment and makes full use of the base 10 panel, so that the components located on the base 10 can be more compact.

[0039] Furthermore, by using the elastic element 22 to adaptively adjust the position of the mounting base 30 connected to it, that is, to adjust the height of the mounting base 30, when changing wires of different diameters or materials, it is not necessary to change the arrangement of the first winding wheel 12. It can also quickly adapt to tension changes and provide a stable tension output for the winding equipment, reducing the impact of tension fluctuations on winding quality.

[0040] Specifically, the elastic element 22 can be a spring in a compressed state, which can continuously apply a downward elastic force to the mounting base 30. When the wire is wound, the wire will give the elastic element 22 a reaction force. When the reaction force is too large (i.e. the wire is too tight), the elastic element 22 will cause the mounting base 30 to contract, thereby loosening the wire.

[0041] See Figures 4 to 5 As shown, Figure 4 This application shows a schematic diagram of the internal structure of an embodiment of the base 10 of a tensioning mechanism. Figure 1 ; Figure 5 This application shows a schematic diagram of the internal structure of an embodiment of the base 10 of a tensioning mechanism. Figure 2 .

[0042] In some embodiments, the base 10 is further provided with a mounting groove 13 extending along a first direction, wherein a magnetic powder brake 14 is embedded in the base 10, penetrating the mounting groove 13. The magnetic powder brake 14 is a component composed of a rotor, a stator, magnetic powder, a coil, etc. The rotor of the magnetic powder brake 14 is used to connect with the third winding wheel 140, so that when the magnetic powder brake 14 is energized, the magnetic powder can form a magnetic flux under the action of an electromagnetic field to adjust the rotational resistance of the third winding wheel 140. Thus, when the current of the magnetic powder brake 14 is adjusted, the tension of the third winding wheel 140 can be changed accordingly.

[0043] Combination Figure 6 As shown, Figure 6 This application provides a three-dimensional structural schematic diagram of an embodiment of a tensioning mechanism. Figure 2 In some embodiments, the base 10 is further provided with an inner cavity 15, wherein a support seat 16 and a support rod 17 embedded in the support seat 16 are fixedly disposed within the inner cavity 15.

[0044] In this embodiment, compared to the current base 10 which is only a single plate, the base 10 is provided with an inner cavity 15, that is, the base 10 is a box-type structure, which can increase the structural strength of the base 10 and protect the mounting components located inside the base 10, preventing dust, debris, etc. from entering. The support base 16 and support rod 17 are connected to the whole machine, allowing the tensioning mechanism to be erected outside the winding equipment, making full use of the space above the winding equipment. Exemplarily, the bottom of the support rod 17 is also provided with a locking seat, which can engage with the frame of the winding equipment, thereby further increasing the stability of the tensioning mechanism. Exemplarily, combined with... Figure 1 As shown, the base 10 is also equipped with multiple clips so that workers can directly remove the back cover of the base 10.

[0045] In some implementation schemes, combined Figure 1 As shown, the support base 16 is provided with a plurality of first locking holes 161 spaced apart along a first direction, wherein the base 10 is provided with second locking holes 162 corresponding to the first locking holes 161. By connecting the plurality of first locking holes 161 and second locking holes 162 to each other, the connection area between the base 10 and the support base 16 can be increased, thereby making the center of gravity of the base 10 more biased towards the support rod 17. For example, Figure 6 The first locking hole 161 shown is set at a certain distance and has three holes.

[0046] In some embodiments, the base 10 is further provided with a first through groove 18 parallel to the guide bar 21, wherein the first limiting seat 23 is fixed in the first through groove 18. Providing the first through groove 18 to install the first limiting seat 23 can further improve the tension adjustment range of the elastic adjustment assembly 20.

[0047] In some embodiments, the base 10 is further provided with a second mounting position 19, which is located at the bottom of the guide bar 21 and is used to fix the second limiting seat 24. In this embodiment, the second limiting seat 24 is fixedly set so that when adjusting the tension adjustment range of the elastic adjustment component 20, only the first limiting seat 23 needs to be adjusted.

[0048] See Figure 7 As shown, Figure 7 This application provides a three-dimensional structural schematic diagram of an embodiment of a tensioning mechanism. Figure 3 .

[0049] In some embodiments, the elastic adjustment assembly 20 is further provided with a buffer pad 25, which is respectively sleeved on the guide strip 21 and located between the second limiting seat 24 and the mounting seat 30 along the first direction. In this embodiment, the buffer pad 25 can effectively buffer the collision between the mounting seat 30 and the second limiting seat 24. Exemplarily, the buffer pad 25 is made of rubber.

[0050] In some embodiments, this application also provides a winding device, including the above-described tensioning mechanism and a frame connected to the support rod 17 of the tensioning mechanism.

[0051] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
