Description

Technical Field

[0001] This utility model relates to the technical field of voice coil winding equipment, and in particular to a tension regulator. Background Technology

[0002] If the copper wire tension is insufficient during the voice coil winding process, the copper wire will become loose and uneven, affecting the winding accuracy of the voice coil. If the copper wire tension is too high, the copper wire is prone to breakage, and the internal stress of the wound voice coil will be too high, which may cause deformation or noise during operation. Therefore, tension adjustment equipment is used to control the copper wire tension during the voice coil winding process. Appropriate and constant tension is the key to ensuring that the copper wire is tightly and evenly wound on the coil frame.

[0003] The existing document with publication number CN 209758725 U discloses a winding tension adjustment device, which includes upper and lower chassis and uses sensors, tension rods and other structures to adjust the tension of copper wire. However, the applicant found that the tension adjustment device has shortcomings. Due to the workshop environment or the copper wire itself, impurities may be attached to the surface of the copper wire. During the winding process of the copper wire passing through the tension regulator, the impurities may affect the adhesion of glue or damage the copper wire, which may lead to inter-turn short circuits in the voice coil. Utility Model Content

[0004] The purpose of this invention is to provide a tension regulator to improve the problem of high voice coil failure rate caused by insufficient cleanliness of the copper wire surface during the voice coil winding process.

[0005] To achieve the above objectives, this utility model provides a tension regulator, including a housing, a tension adjustment component is provided on the side wall of the housing, and a guide wheel assembly and a cleaning unit are provided on the lower front baffle of the housing. The guide wheel assembly pulls a copper wire to be fed into the tension adjustment component.

[0006] The cleaning unit includes a movable rod, a docking seat, and an elastic element. The docking seat is clamped and fixed to the lower baffle of the chassis. The head of the movable rod passes through the docking seat and is fixed with a clamping plate. Wool felt is glued to the opposite side of the clamping plate and the docking seat. The elastic element is sleeved on the movable rod, and its two ends abut against the tail of the movable rod and the docking seat, respectively.

[0007] In the process of winding a voice coil using copper wire, the tension regulator of this application is used to adjust the tension of the copper wire, and the cleaning unit is added to clean the copper wire to meet the surface cleanliness requirements during the copper wire winding process. Specifically, during the process of guiding the copper wire into the tension adjustment assembly using the guide wheel group, the copper wire will first pass through the cleaning unit. Under the action of the elastic element, the movable rod clamps the copper wire in the felt between the docking seat and the clamping plate. After the copper wire is pulled through the felt, the surface of the copper wire can be cleaned.

[0008] The tail of the movable rod is provided with a mating head, which connects to the end face of the movable rod and abuts against one end of the elastic element to cooperate with the elastic element to limit the displacement of the movable rod.

[0009] The end face of the mating head abuts against the elastic element. After the elastic element is installed on the movable rod, it always maintains an extending motion tendency so that the clamping plate and the mating seat are kept in a clamping state.

[0010] The docking seat has a through hole that passes through the docking seat along its axis. The docking seat also has a limiting groove on its outer periphery. The docking seat is fixed to the lower baffle through the limiting groove. The through hole is adapted to the movable rod.

[0011] The through hole is adapted to the movable rod. When the wool felt needs to be replaced, the movable rod can be pushed to create a gap between the docking seat and the clamping plate to meet the replacement requirements. After the replacement is completed, the movable rod is released, and under the action of the elastic element, the docking seat can be driven to dock with the clamping plate again.

[0012] The tension adjustment assembly includes a tension rod, a tension spring, and an adjustment block. The tension rod is rotatably connected to the chassis. The two ends of the tension spring are respectively connected to the tension rod and the adjustment block. The adjustment block is disposed on the side wall of the chassis.

[0013] The tension bar serves as a device before the copper wire is wound, and works with the tension spring to adjust the tension of the copper wire. Specifically, the rotation angle of the tension bar is adjusted so that the tension of the copper wire entering the tension bar can be further adjusted. The adjustment block works with the tension spring to adjust the extension length of the tension spring to change the state of the tension bar.

[0014] The tension bar includes a rod body capable of elastic deformation and a rotating shaft. The head of the rod body is provided with a fixed pulley, and the tail of the rod body is connected to the rotating shaft, which is mounted on the side wall of the chassis.

[0015] In this process, after the rod body, in conjunction with the rotating shaft, has undergone a rough adjustment of its rotation angle, the pitch angle of the rod body is further adjusted under the action of the tension spring.

[0016] The guide wheel assembly includes a wire feeding wheel, a pulley, and a tension wheel. The wire feeding wheel is located on the front side of the lower baffle and is rotatably connected to the lower baffle. The pulley is used to cooperate with the wire feeding wheel to pull the copper wire to the tension adjustment assembly. The tension wheel is located on the lower baffle and is connected to the copper wire that has passed through the wire feeding wheel.

[0017] The wire feeding wheel is used to adjust its rotation speed according to the tension, thereby changing the copper wire conveying speed. The pulley is used to change the running path of the copper wire passing through the cleaning unit and finally deliver the copper wire to the tension adjustment component. The tension wheel is connected to the copper wire passing through the wire feeding wheel to obtain the tension value of the copper wire. The tension data can be obtained by converting the copper wire tension into a small displacement of the tension wheel. Since there are many existing technologies, the structure is not specifically described in this application.

[0018] Each pulley includes a connecting bracket and a guide wheel assembly. The connecting bracket is fixedly connected to the side wall of the chassis, and the guide wheel assembly is disposed inside the connecting bracket and rotatably connected to the connecting bracket.

[0019] The connecting bracket is used to house the guide wheel assembly, allowing the guide wheel assembly to rotate within the connecting bracket.

[0020] The guide wheel assembly includes a rotating shaft and a wheel body. The wheel body is rotatably connected to the connecting bracket via the rotating shaft, and a groove is also provided in the middle of the wheel body.

[0021] The rotating shaft is rotatably connected to the connecting bracket. After the wheel is connected to the rotating shaft, it can rotate within the connecting bracket, allowing the movement of the copper wire passing through the wheel to occur within the wire groove.

[0022] This utility model discloses a tension regulator that, based on existing technology, adds a cleaning unit. The clamping plate and the docking seat are formed by interaction, and wool felt is bonded between the docking seat and the clamping plate. After the copper wire passes through, the surface of the copper wire is cleaned, so as to avoid various problems caused by impurities on the surface of the copper wire during the subsequent voice coil winding process.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] Please see Figures 1 to 5 This utility model provides a tension regulator, including a housing 1. A tension adjustment component 2 is provided on the side wall of the housing 1. A guide wheel assembly 3 and a cleaning unit 4 are provided on the lower baffle 19 on the front side of the housing 1. The guide wheel assembly 3 pulls a copper wire to be fed into the tension adjustment component 2.

[0032] The cleaning unit 4 includes a movable rod 11, a docking seat 12, and an elastic element 13. The docking seat 12 is clamped and fixed on the lower baffle 19 of the housing 1. The head of the movable rod 11 passes through the docking seat 12 and is fixed with a clamping plate 14. Wool felt 15 is glued to both the clamping plate 14 and the docking seat 12 on opposite sides. The elastic element 13 is sleeved on the movable rod 11, and both ends of the elastic element 13 abut against the tail of the movable rod 11 and the docking seat 12, respectively.

[0033] In this embodiment, the chassis 1 can be independently installed on the side of the voice coil winding equipment. The copper wire to be processed is coiled and installed on the lower side of the chassis 1. After the copper wire ends pass through various components, the preparation work for subsequent winding is completed. Then, the copper wire ends are sequentially sent through the cleaning unit 4 and the guide wheel group 3 to the tension adjustment assembly 2, thereby completing the cleaning and tension adjustment process of the copper wire. Under the action of the elastic element 13, the movable rod 11 drives the clamping plate 14 to be in a clamping state on the docking seat 12, while the wool felt 15 cleans the copper wire during the process of the copper wire passing through.

[0034] Furthermore, the tail of the movable rod 11 is provided with a mating head 16, and the end face of the mating head 16 is connected to the end face of the movable rod 11 and abuts against one end of the elastic member 13 to cooperate with the elastic member 13 to limit the displacement of the movable rod 11.

[0035] In this embodiment, the end face of the mating head 16 connected to the movable rod 11 mainly engages with the elastic element 13, so that the elastic element 13 maintains a compressed state to apply force to the mating head 16, thereby driving the clamping plate 14 and the mating seat 12 into a clamped state.

[0036] Furthermore, the docking seat 12 is provided with a through hole 17, which passes through the docking seat 12 along the axis of the docking seat 12. The docking seat 12 is also provided with a limiting groove 18 on its outer periphery. The docking seat 12 is fixed to the lower baffle 19 through the limiting groove 18. The through hole 17 is adapted to the movable rod 11.

[0037] In this embodiment, the through hole 17 is adapted to the movable rod 11. The movable rod 11, in conjunction with the mating head 16, can move axially within the through hole 17. The limiting groove 18 is provided to fix the docking seat 12 on the lower baffle 19 to accommodate the displacement of the movable rod 11.

[0038] Furthermore, the tension adjustment assembly 2 includes a tension rod 21, a tension spring 22, and an adjustment block 23. The tension rod 21 is rotatably connected to the chassis 1. The two ends of the tension spring 22 are respectively connected to the tension rod 21 and the adjustment block 23. The adjustment block 23 is disposed on the side wall of the chassis 1.

[0039] In this embodiment, after the tension rod 21 completes the initial adjustment of the pitch angle, the angle of the adjustment block 23 can be adjusted to change the length of the tension spring 22, thereby changing the force applied to the tension rod 21, and thus finely adjusting the tension of the copper wire by adjusting the elastic deformation state of the tension rod 21.

[0040] Furthermore, the tension bar 21 includes a rod body 24 capable of elastic deformation and a rotating shaft 25. The head of the rod body 24 is provided with a fixed pulley 26, and the tail of the rod body 24 is connected to the rotating shaft 25. The rotating shaft 25 is installed on the side wall of the housing 1.

[0041] In this embodiment, the rod 24 can undergo elastic deformation, which allows the rod 24 to deform in conjunction with the tension spring 22 to meet the tension adjustment of the copper wire.

[0042] Furthermore, the guide wheel assembly 3 includes a wire feeding wheel 31, a pulley 32, and a tension wheel 33. The wire feeding wheel 31 is disposed on the front side of the lower baffle 19 and is rotatably connected to the lower baffle 19. The pulley 32 is used to cooperate with the wire feeding wheel 31 to pull the copper wire to the tension adjustment assembly 2. The tension wheel 33 is disposed on the lower baffle 19 and is connected to the copper wire passing through the wire feeding wheel 31.

[0043] In this embodiment, the wire feeding wheel 31 can change its rotation speed to change the copper wire transport speed, while the pulley 32 is mainly used to change the transport direction of the copper wire, and the tension wheel 33 is used to measure the tension data of the copper wire and display it on the display screen, so as to obtain the tension data in a timely manner during the adjustment process.

[0044] Furthermore, the pulley 32 includes a connecting bracket 34 and a guide wheel assembly 35. The connecting bracket 34 is fixedly connected to the chassis 1, and the guide wheel assembly 35 is disposed inside the connecting bracket 34 and rotatably connected to the connecting bracket 34.

[0045] The connecting bracket 34 is mainly used to fix the chassis 1, and the guide wheel assembly 35 is rotatably installed in the connecting bracket 34 to facilitate the transport of copper wires.

[0046] Furthermore, the guide wheel assembly 35 includes a rotating shaft 36 and a wheel body 37. The wheel body 37 is rotatably connected to the connecting bracket 34 through the rotating shaft 36, and a groove 38 is also provided in the middle of the wheel body 37.

[0047] The rotating shaft 36 cooperates with the wheel 37, allowing the wheel 37 to rotate within the connection via the rotating shaft 36. A groove is formed in the middle of the wheel 37 to restrict the position of the copper wire, facilitating subsequent tension adjustment.

[0048] The specific implementation process is as follows: the copper wire end first passes between the docking seat 12 and the clamping plate 14, and then is guided by the guide wheel to the wire feeding wheel 31. The copper wire fed from the wire feeding wheel 31 passes through the tension wheel 33 to obtain copper wire tension data, and then is guided by the guide wheel to the fixed pulley 26 on the tension rod 21. During this process, the wire feeding speed can be changed by changing the rotation speed of the wire feeding wheel 31, and the tension of the copper wire can also be adjusted by adjusting the pitch angle of the tension rod 21 and the rotation angle of the adjusting block 23.

[0049] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
