Description
Technical Field
[0001] This utility model belongs to the field of reel closing machine technology, specifically relating to an automatic voice coil wire reel closing machine. Background Technology
[0002] The voice coil is the current-carrying coil component in a loudspeaker. As a core component of the electrodynamic loudspeaker's vibration system, its performance directly affects the loudspeaker's sound intensity characteristics, sound intensity level, impedance curve, distortion, transient response, various parameters, and ultimately, sound quality. During voice coil production, an automatic winding machine is used to neatly wind the wire onto a reel. In operation, workers load the reel into the winding machine, and the rotation of the reel pulls the wire in an orderly winding motion, thus completing the winding operation.
[0003] However, current automatic winding machines have certain limitations when installing reels: their clamping mechanisms are typically only suitable for reels of a fixed diameter and lack size adjustment capabilities. When processing reels of different sizes, the corresponding clamping components must be replaced. This process is not only cumbersome but also increases the workload for operators and affects production efficiency.
[0004] Chinese utility model patent CN223254575U discloses an automatic voice coil wire reeling machine, relating to the field of reeling machines. It includes a chassis, a coil, a clamping assembly, and a wire management assembly. The clamping assembly includes a rotating disk, a linear limiting disk, a rotating block, an L-shaped connecting rod, an arc-shaped limiting disk, an inner support block, and a limiting shaft. The wire management assembly includes a first threaded rod, a moving block, a wire management ring, a second threaded rod, a blocking block, a second sensor, a connecting plate, and a first sensor. Rotating the arc-shaped limiting disk causes the L-shaped connecting rod to slide within the arc-shaped limiting groove, while the rotating block slides within a straight groove on the outer surface of the linear limiting disk. This ultimately causes the inner support block to move outwards to support the reel. The second threaded rod moves the blocking block, which in turn moves the connecting plate and the first sensor. The first sensor determines the length of the reel. When the moving block moves close to the blocking block, a first actuator controls the second servo motor to reverse, ultimately controlling the stroke of the wire management ring. However, its clamping components have a complex structure and are cumbersome to operate. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention utilizes a linear motor-driven lever mechanism in the clamping assembly to tighten the pull strap that passes over the winding mold, thereby laterally clamping and securing the winding drum. Subsequently, the winding shaft rotates to complete the winding. After winding, the linear motor-driven telescopic rod of the pressing assembly extends, catches the wire, and retracts. Its pressure head engages with the arc-shaped cutter on the sleeve to form a shearing action, pressing the wire tail against the rubber pad while actively cutting it off.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1:
[0023] This utility model provides an automatic voice coil wire reeling machine, including a frame 1. A worktable 2 is fixedly mounted on the frame 1. A winding assembly 3 and a guide assembly 4 are fixedly mounted on the worktable 2. The winding assembly 3 includes a servo motor 5 and a winding shaft 6. A rotary table 7 is fixedly mounted on the winding shaft 6. A winding mold 9 is fixedly mounted on the winding shaft 6 via quick-release bolts 8. A clamping assembly 10 and a wire pressing assembly 11 are fixedly mounted on the rotary table 7. The clamping assembly 10 includes a connecting block 12, a first linear motor 13, a connecting rod 14, and a fixed seat 15. The fixed seat 15 is connected by a shaft. 16 is movably connected to connecting rod 14. Connecting block 12 is fixedly connected to connecting rod 14 via pull strap 17. The drive end of first linear motor 13 is fixedly connected to connecting rod 14 via rotating shaft structure 18. The wire pressing assembly 11 includes mounting base 19 and second linear motor 20. Mounting base 19 has sleeve 21, on which telescopic rod 22 is movably mounted. Telescopic rod 22 has pressing head 23. The drive end of second linear motor 20 is fixedly connected to telescopic rod 22. Sleeve 21 is fixedly mounted with cutter 24 and rubber pad 25. Workbench 2 is fixedly mounted with wire reel frame 26. Guide assembly 4 includes moving device 27, moving platform 28, and fixed frame 29. The drive end of moving device 27 is fixedly connected to moving platform 28. Moving platform 28 is fixedly mounted with fixed frame 29. Fixed frame 29 is fixedly mounted with guide tube 30, flywheel 31, and guide ring 32. Rubber pad 25 is made of silicone rubber. The frame 1 is fixedly mounted with a housing 33, and a foldable dustproof plate 34 is fixedly mounted between the housing 33 and the guide assembly 4. The pull strap 17 is made of plastic steel.
[0024] Through the above technical solution, this utility model uses the linear motor driven lever mechanism of the pressing component 10 to tighten the pull strap 17 that passes over the winding mold 9, thereby clamping and fixing the winding drum from the side; then, the winding shaft 6 rotates to complete the winding; after the winding is completed, the linear motor driven telescopic rod 22 of the pressing component 11 extends and retracts after touching the wire, and uses its pressing head 23 to form a shearing engagement with the arc-shaped cutter 24 on the sleeve 21 to actively cut the wire tail while pressing it against the rubber pad 25, thereby realizing the rapid replacement of the winding drum and assembly line operation, effectively improving production efficiency.
[0025] Specifically, the first linear motor 13 of the clamping assembly 10 drives the connecting rod 14, which, through the lever action with the shaft 16 as the fulcrum, tightens the pull belt 17, causing it to pass around the winding mold 9 on the winding shaft 6, thereby clamping the edge of the winding drum sleeved on it from the side; then, the servo motor 5 of the winding assembly 3 drives the winding shaft 6 to rotate for winding; when the winding is finished, the pressing assembly 11 starts to operate, and its second linear motor 20 drives the telescopic rod 22 to extend, so that the wire is placed on the pressing head 23. Then, the telescopic rod 22 retracts, so that the pressing head 23 cooperates with the rubber pad 25 fixed on the sleeve 21 to press the wire. At the same time, the pressing head 23 forms a shearing motion with the cutter 24 fixed on the sleeve 21 to cut the wire; finally, the clamping assembly 10 is released, and the wound voice coil wire can be removed. Different sizes of winding molds 9 can be replaced by quick-release bolts 8 to adapt to production needs, thereby realizing efficient and automated cyclic winding operation.
[0026] Example 2:
[0027] In this embodiment, the frame 1 serves as the overall support structure, with a horizontal worktable 2 fixedly mounted on its top. A winding assembly 3 and a guide assembly 4 are respectively arranged on the surface of the worktable 2. The winding assembly 3 includes a servo motor 5 and a winding shaft 6. The servo motor 5 is coaxially connected to the winding shaft 6 via a coupling, enabling precise control of the rotational speed and angle of the winding shaft 6. A rotary table 7 is fixedly mounted at the front end of the winding shaft 6, and the rotary table 7 rotates synchronously with the winding shaft 6 via a keyway. A winding mold 9 is detachably mounted on the outer surface of the winding shaft 6 via quick-release bolts 8. The winding mold 9 can be replaced according to the size of the winding drum to adapt to the production needs of different specifications of voice coil wire.
[0028] A clamping assembly 10 and a wire clamping assembly 11 are integrated and installed on the rotary table 7. The clamping assembly 10 includes a connecting block 12, a first linear motor 13, a connecting rod 14, and a fixing seat 15. The fixing seat 15 is welded to the side of the rotary table 7 and is movably connected to the connecting rod 14 via a shaft 16, allowing the connecting rod 14 to rotate around the shaft 16. The connecting block 12 is fixed to the other side of the rotary table 7 and is connected to the end of the connecting rod 14 via a flexible pull strap 17. The drive end of the first linear motor 13 is fixed to the middle of the connecting rod 14 via a rotating shaft structure 18. When the first linear motor 13 extends or retracts, it drives the connecting rod 14 to swing around the shaft 16, thereby tightening or loosening the pull strap 17. The pull strap 17 passes around the outside of the winding mold 9 and, through tension, laterally clamps the winding drum fitted on the winding mold 9, achieving rapid fixation of the winding drum.
[0029] The pressure assembly 11 includes a mounting base 19 and a second linear motor 20. The mounting base 19 is fixed to the edge of the rotary table 7 and has a cylindrical sleeve 21. A telescopic rod 22 is movably mounted inside the sleeve 21, and a hemispherical pressure head 23 is provided at the front end of the telescopic rod 22. The drive end of the second linear motor 20 is fixedly connected to the rear end of the telescopic rod 22, which can control the telescopic rod 22 to move axially along the sleeve 21. An arc-shaped cutter 24 and an elastic rubber pad 25 are fixedly mounted on the outer wall of the sleeve 21. The cutting edge of the cutter 24 faces the movement trajectory of the pressure head 23, and the rubber pad 25 is located below the cutter 24 for cushioning and sealing.
[0030] A wire reel holder 26 is fixedly mounted on the side of the workbench 2 for holding the voice coil wire coil to be wound. The guide assembly 4 is located between the wire reel holder 26 and the winding assembly 3, and includes multiple guide wheels and a tension adjustment mechanism to ensure that the wire maintains stable tension and the correct path during the winding process.
[0031] During operation, the operator first places the spool onto the winding mold 9 and activates the clamping assembly 10. The first linear motor 13 retracts, leveraging the connecting rod 14 to tighten the pull strap 17, ensuring it grips and secures the spool tightly against its outer edge. Subsequently, the servo motor 5 drives the winding shaft 6 to rotate, guiding the wire evenly onto the spool via the guide assembly 4. When the winding reaches the set length, the clamping assembly 11 begins operation: the second linear motor 20 pushes the telescopic rod 22 to extend, allowing the wire to rest on the surface of the clamping head 23. The telescopic rod 22 then quickly retracts, causing the clamping head 23 to press the wire against the rubber pad 25. During this process, the clamping head 23 and the cutter 24 perform a shearing motion, neatly cutting the wire. Simultaneously, the clamping head 23 and the rubber pad 25 work together to clamp the wire end, preventing loosening. Finally, the clamping assembly 10 releases, allowing the operator to remove the wound voice coil spool and replace the winding mold 9 using the quick-release bolt 8 to continue the next round of work.
[0032] This embodiment achieves rapid clamping of the spool and automatic cutting of the wire through the lever-type tensioning mechanism of the clamping component 10 and the shearing clamping of the wire pressing component 11, effectively simplifying the operation process. The replaceable design of the winding die 9 allows the equipment to adapt to various spool sizes, and the guide component 4 ensures stable wire tension during the winding process. The entire system achieves efficient and automated cycle of voice coil wire winding through the coordinated control of the servo motor 5 and the linear motor.
[0033] Example 3:
[0034] In this embodiment, the winding assembly 3 is fixedly installed on the workbench 2, including a servo motor 5 and a winding shaft 6. The winding shaft 6 is fixedly installed on the winding mold 9 by quick-release bolts 8, which facilitates quick replacement of molds of different sizes to accommodate various specifications of spools. The winding shaft 6 is also fixedly connected to a rotary table 7, on which a clamping assembly 10 and a wire pressing assembly 11 are installed. The clamping assembly 10 consists of a connecting block 12, a first linear motor 13, a connecting rod 14, and a fixed seat 15. The fixed seat 15 is movably connected to the connecting rod 14 by a shaft 16 to form a lever structure. The connecting block 12 is fixed to the connecting rod 14 by a pull strap 17. When the first linear motor 13 drives the connecting rod 14, with the shaft 16 as the fulcrum, the pull strap 17 is tightened and passes around the winding mold 9, clamping the edge of the spool from the side to achieve a stable fixation. The wire pressing assembly 11 includes a mounting base 19 and a second linear motor 20. The mounting base 19 has a sleeve 21, on which a telescopic rod 22 is movably mounted. A pressing head 23 is located at the end of the telescopic rod 22. The second linear motor 20 drives the telescopic rod 22 to move. A cutter 24 and a rubber pad 25 are fixedly mounted on the sleeve 21 for wire pressing and cutting. The worktable 2 also has a wire reel rack 26 fixedly mounted for holding wire reels.
[0035] The guiding assembly 4 includes a moving device 27, a moving platform 28, and a fixed frame 29. The moving device 27 consists of a high-precision servo drive motor, a lead screw, and a slide rail. The drive end is fixedly connected to the moving platform 28, and the fixed frame 29 is fixedly mounted on the moving platform 28. A guide ring 32, a flywheel 31, and a guide tube 30 are sequentially fixed on the fixed frame 29 to form a wire guiding path. The wire on the wire reel frame 26 passes through the guide ring 32, the flywheel 31, and the guide tube 30 in sequence, and finally the wire end is fixed on the wire pressing assembly 11 for easy automatic winding. During the winding operation, the servo drive motor drives the moving platform 28 to move along the slide rail, and the lead screw transmission achieves precise displacement, so that the wire is evenly wound on the winding drum, avoiding wire accumulation or loosening, and ensuring winding quality.
[0036] In the specific working process, the spool is first installed on the winding mold 9. The clamping assembly 10 is activated, and the first linear motor 13 drives the connecting rod 14 to tighten the pull belt 17 through the lever principle, fixing the spool from the side. Subsequently, the servo motor 5 of the winding assembly 3 starts, driving the winding shaft 6 to rotate. At the same time, the servo drive motor of the guide assembly 4 controls the movement of the moving table 28 to guide the wire to wind evenly. When the winding is finished, the pressing assembly 11 starts working. The second linear motor 20 drives the telescopic rod 22 to extend, so that the wire rests on the pressing head 23. Then the telescopic rod 22 retracts, and the pressing head 23 cooperates with the rubber pad 25 on the sleeve 21 to press the end of the wire. At the same time, the pressing head 23 and the cutter 24 form a shearing action to cut the wire. After completion, the clamping assembly 10 is released, the wound voice coil wire is removed, and the winding mold 9 is replaced by the quick-release bolt 8 to achieve rapid cycle operation.
[0037] This embodiment precisely controls the winding path of the wire through the moving device 27 of the guide assembly 4, combined with the clamping and pressing functions of the winding assembly 3, achieving efficient and automated winding of the voice coil wire. The servo drive motor, lead screw, and slide rail of the moving device 27 work together to ensure uniform distribution of the wire during winding, avoiding the cumbersome replacement problems caused by the fixed clamping mechanism in traditional equipment. The overall structure simplifies the operation process, improves production efficiency, is suitable for the rapid processing of various specifications of winding spools, and meets the high standards required for voice coil production.
[0038] Example 4:
[0039] In this embodiment, the rubber pad 25 is made of silicone rubber, which has good elasticity and wear resistance. It can provide stable cushioning during wire clamping, avoid damage to the wire surface, and ensure the precise execution of the shearing action. The entire device includes core components such as the frame 1, workbench 2, winding assembly 3, and guide assembly 4. The winding shaft 6 is fixedly mounted to the winding mold 9 by quick-release bolts 8, which facilitates quick replacement according to different winding drum sizes, effectively solving the problems of single-size clamping mechanisms and cumbersome operation in traditional equipment.
[0040] In the specific operation process, the spool is first placed on the winding mold 9, and then the clamping assembly 10 is activated. The clamping assembly 10 includes a connecting block 12, a first linear motor 13, a connecting rod 14, and a fixing seat 15. The fixing seat 15 is movably connected to the connecting rod 14 via a shaft 16, forming a lever structure. The drive end of the first linear motor 13 is fixed to the connecting rod 14 via a rotating shaft structure 18. When the first linear motor 13 is activated, it drives the connecting rod 14 to rotate around the shaft 16, thereby tightening the pull strap 17 on the connecting block 12. The pull strap 17 passes around the winding mold 9 and hugs the edge of the spool from the side, achieving a firm fixation. This process does not require manual adjustment of the clamping components and can adapt to spools of different diameters, greatly simplifying the operation steps. After the fixation is completed, the servo motor 5 of the winding assembly 3 drives the winding shaft 6 to rotate, causing the spool to wind the wire. The guide assembly 4 ensures that the wire is arranged in an orderly manner and avoids tangling.
[0041] After the winding operation is completed, the wire pressing assembly 11 begins operation. The wire pressing assembly 11 includes a mounting base 19 and a second linear motor 20. A sleeve 21 is mounted on the mounting base 19, and a telescopic rod 22 is movably mounted on the sleeve 21. A pressing head 23 is located at the end of the telescopic rod 22. The drive end of the second linear motor 20 is fixedly connected to the telescopic rod 22, driving the telescopic rod 22 to extend, allowing the wire to rest on the pressing head 23. Subsequently, the telescopic rod 22 retracts, causing the pressing head 23 to engage with the rubber pad 25 on the sleeve 21, pressing the wire tail tightly. Simultaneously, a cutter 24 fixedly mounted on the sleeve 21 forms a shearing motion with the pressing head 23, actively cutting the wire tail as it is pressed. The silicone rubber material of the rubber pad 25 plays a crucial role in this process; its softness protects the wire from damage and enhances the pressing effect, ensuring a clean and crisp cutting action and preventing loose wire ends. The entire pressing and cutting process is automated, requiring no manual intervention, significantly improving operational continuity and safety.
[0042] After the wire is cut, the first linear motor 13 of the clamping assembly 10 reverses direction, releasing the pull strap 17 and releasing the fixation on the spool. The operator can easily remove the coiled voice coil wire and quickly change the winding die 9 using the quick-release bolt 8 to accommodate the next batch of spools of different specifications. This design not only enables rapid spool replacement but also supports assembly line operations, allowing for cyclical winding, clamping, and cutting operations. Through the lever tensioning mechanism of the clamping assembly 10 and the automatic clamping and cutting function of the wire clamping assembly 11, this embodiment effectively improves the automation level and production efficiency of voice coil wire winding. Furthermore, the introduction of the silicone rubber pad 25 further optimizes the wire processing quality, making it suitable for large-scale voice coil production environments.
[0043] Example 5:
[0044] In this embodiment, a housing 33 is fixedly installed on the frame 1, and a foldable dustproof plate 34 is fixedly installed between the housing 33 and the guide assembly 4. This dustproof plate is designed to be foldable, allowing it to be flexibly unfolded or retracted according to the equipment's operating status. Without affecting the normal operation of the guide assembly 4, it effectively prevents external dust and foreign objects from entering the guide assembly 4. The guide assembly 4, as a key component in the winding machine responsible for guiding the precise winding of the wire, contains multiple precision guide wheels and sensors. These components require high cleanliness; if dust or foreign objects adhere to them, it may cause wire misalignment, uneven winding, or sensor misjudgment, thereby reducing winding accuracy and product yield. By setting the foldable dustproof plate 34, the guide assembly 4 can be kept in a closed state during equipment operation, preventing the intrusion of pollutants such as dust and fiber debris from the production environment, ensuring the long-term stable operation of the guide assembly 4.
[0045] In practical applications, the foldable dustproof panel 34 is typically made of flexible, wear-resistant materials, such as high-strength fabric or composite plastic film. Its edges are connected to the housing 33 and the guide assembly 4 frame via fasteners, forming a continuous protective barrier. The folding mechanism of the dustproof panel can be implemented manually or automatically. For example, during equipment maintenance or adjustment, operators can easily fold it to one side for easy cleaning or inspection of the guide assembly 4; during normal production, the dustproof panel automatically unfolds to cover the top and side openings of the guide assembly 4, achieving all-around protection. This design not only simplifies daily maintenance procedures but also avoids the space occupation and operational inconvenience problems that may be caused by traditional fixed protective covers.
[0046] Furthermore, the connection between the foldable dustproof plate 34 and the housing 33 and guide assembly 4 is equipped with a sealing structure, such as a rubber strip or magnetic sealing edge, to enhance the dustproof effect. When the dustproof plate is fully unfolded, it fits tightly against the equipment components, forming a sealed space that effectively isolates the external environment. At the same time, the foldable nature of the dustproof plate allows it to adapt to the spatial changes of the guide assembly 4 under different working conditions. For example, when the guide assembly 4 is repositioned or the cable path is changed, the dustproof plate can deform accordingly without causing interference. This dynamic protection method ensures that the guide assembly 4 is always in a clean state, thereby maintaining high-precision guidance function.
[0047] From a working principle perspective, the guide assembly 4 ensures that the voice coil wire maintains constant tension and the correct path during winding through multiple guide wheels and a tension control mechanism. Any external interference could disrupt this balance. The foldable dustproof plate 34 eliminates potential problems such as increased rotational resistance of the guide wheels, wire surface contamination, or obstruction of sensor optical components caused by dust accumulation through physical isolation. Furthermore, regular cleaning or replacement of the dustproof plate can be integrated into the equipment maintenance plan, further extending the service life of the guide assembly 4. Overall, this embodiment, by integrating the foldable dustproof plate 34, significantly improves the environmental adaptability and long-term operational reliability of the voice coil wire winding machine without substantially increasing equipment complexity, making it particularly suitable for industrial scenarios with high cleanliness requirements, such as electronic component manufacturing.
[0048] Example 6:
[0049] In this embodiment, the clamping assembly 10 uses a plastic-steel pull strap 17, combined with a lever drive mechanism, to achieve rapid fixing and releasing of winding drums of different specifications. Specifically, the frame 1 serves as an overall support structure, on which a workbench 2 is fixedly installed. The workbench 2 integrates a winding assembly 3 and a guide assembly 4. The winding assembly 3 includes a servo motor 5 and a winding shaft 6. The winding shaft 6 is fixed to the winding mold 9 by quick-release bolts 8 and connected to a rotary table 7. The rotary table 7 is equipped with the clamping assembly 10 and the wire pressing assembly 11. The clamping assembly 10 consists of a connecting block 12, a first linear motor 13, a connecting rod 14, and a fixed seat 15. The fixed seat 15 is movably connected to the connecting rod 14 through a shaft 16 to form a lever fulcrum. The connecting block 12 is fixed to the connecting rod 14 through the plastic-steel pull strap 17. The drive end of the first linear motor 13 is connected to the connecting rod 14 through a rotating shaft structure 18.
[0050] When the equipment starts, the first linear motor 13 drives the connecting rod 14 to rotate around the shaft 16, using the lever principle to tighten the plastic steel pull strap 17, causing it to pass around the winding mold 9 and hug the side edge of the winding drum, thus firmly fixing the winding drum and ensuring stability during the winding process. The plastic steel material has high strength, wear resistance, and deformation resistance, and can withstand repeated tightening and loosening operations, extending its service life. At the same time, its lightweight characteristics reduce motion inertia, improve response speed, and avoid clamping failure due to material fatigue. During the winding process, the servo motor 5 drives the winding shaft 6 to rotate, causing the winding drum to evenly wind the voice coil wire. The guide component 4 ensures that the wire is arranged in an orderly manner, avoiding tangling and mess.
[0051] After winding is completed, the wire pressing assembly 11 begins to operate. It includes a mounting base 19 and a second linear motor 20. The mounting base 19 has a sleeve 21, on which a telescopic rod 22 is movably mounted. A pressing head 23 is located at the end of the telescopic rod 22. The drive end of the second linear motor 20 is fixed to the telescopic rod 22. The second linear motor 20 drives the telescopic rod 22 to extend, allowing the wire to rest on the pressing head 23. The telescopic rod 22 then retracts, and the pressing head 23 engages with the rubber pad 25 on the sleeve 21 to press the wire tail. Simultaneously, the pressing head 23 and the cutter 24 fixed to the sleeve 21 form a shearing motion, actively cutting the wire. This process integrates the pressing and cutting of the wire tail, reducing manual intervention. Finally, the first linear motor 13 of the pressing assembly 10 reverses its direction, releasing the plastic steel pull strap 17. The operator can easily remove the coiled voice coil wire and replace the winding mold 9 using the quick-release bolt 8 to adapt to the production needs of different diameter winding spools. This embodiment simplifies the clamping mechanism, improves equipment versatility and production efficiency, and reduces maintenance costs through the lever drive design of the plastic steel pull strap 17. It is suitable for automated production lines of voice coil wires.
