Description

Technical Field

[0001] This invention belongs to the field of coil manufacturing technology, specifically a horn vibration coil winding device. Background Technology

[0002] A loudspeaker, an electroacoustic component, is a transducer that converts electronic signals into sound. One or more loudspeakers can be used to form a speaker unit, also called a loudspeaker. The coil is one of the important components of a loudspeaker. When an alternating audio current passes through the coil, it causes the coil to generate an alternating current that varies with the audio frequency. This current cuts the magnetic lines of force, producing mechanical vibration, which in turn causes the cone to vibrate and produce sound. During the production of the coil, the enameled wire needs to be evenly wound around the aggregate.

[0003] A Chinese patent with publication number CN112312286B discloses a winding device for a speaker voice coil. It employs two sets of guiding mechanisms to automatically guide the speaker coil, preventing wear during winding. A conveying mechanism automatically transports the speaker coil, and a winding mechanism automatically winds the conveyed coil. This invention achieves automated winding of the speaker coil through the coordinated operation of these mechanisms, eliminating the need for manual winding, thus saving manpower, improving product quality, and increasing work efficiency. It is highly practical.

[0004] In the current technology, when using a winding device to wind a coil, it is necessary to repeatedly put the aggregate on the outside of the fixing component. This process is not only cumbersome, but after each time the aggregate is put on, the fixing component also needs to be adjusted to fix the aggregate. This adjustment process usually requires the use of a complex mechanical structure, which is time-consuming and affects the processing efficiency of the coil.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 6As shown in the figure, a horn vibration coil winding device according to an embodiment of the present invention includes a workbench 1. Support legs 2 are fixedly installed at the four corners of the bottom of the workbench 1. A feeding assembly is provided on the top of the workbench 1, including a feeding box 4. The feeding assembly provides raw material for the winding operation through the feeding box 4. A feeding component is provided on one side of the feeding assembly, including a pusher plate 9. The feeding assembly pushes the raw material inside the feeding box 4 out through the pusher plate 9 for the winding operation. A driving component is provided on the side of the feeding assembly away from the feeding component, providing power for the winding operation. During the winding process... During operation, the aggregate to be wound is placed inside the feeding box 4. The aggregate is vertically arranged due to the constraint of the feeding assembly. After the feeding assembly is activated, it extends towards the drive assembly. During this extension, the feeding assembly pushes out the aggregate at the bottom of the inner side of the feeding box 4 via the pusher plate 9. The aggregate moves towards the drive assembly along with the pusher plate 9. When the feeding assembly contacts the drive assembly, as the feeding assembly continues to move, the drive assembly compresses it. Under this compression, the feeding assembly fixes the aggregate from the inside. Simultaneously, the feeding assembly and drive assembly... Upon contact, a connection is formed, at which point the drive component transmits power to the feeding component. After the aggregate is fixed, the drive component rotates, causing the feeding component to rotate the aggregate. This rotation of the aggregate enables the winding process. After winding is complete, the feeding component resets. During reset, as the feeding component separates from the drive component, it releases the aggregate from its fixation. The aggregate then moves downwards under gravity, overlapping with the unloading component. Therefore, during reset, the unloading component pushes the aggregate off the feeding component, achieving automatic unloading. After reset, the feeding component resumes operation. The component repeats the above operations for the next winding operation. In summary, the present invention achieves a high degree of automation in the entire process from aggregate feeding, fixing, winding to unloading. The aggregate only needs to be fed into the unloading component, and the subsequent work is completed automatically by the device. This reduces manual operation links, lowers labor costs, and avoids errors and interruptions that may be caused by manual operation, greatly improving production efficiency. After completing one winding operation, the device will reset and repeat the operation, enabling continuous winding operations and achieving production continuity. This increases the product output per unit time and meets the needs of large-scale production.

[0022] like Figures 1 to 3As shown, the feeding assembly also includes a fixed base 3 fixedly installed on the top of the workbench 1. The top of the fixed base 3 is fixedly connected to the bottom of the feeding box 4. A front baffle 5 is symmetrically fixedly installed on one side of the feeding box 4. Several aggregate bodies 6 are arranged inside the feeding box 4. A rectangular groove is opened on the side of the feeding box 4 away from the front baffle 5. The height of the rectangular groove is greater than the diameter of the aggregate body 6. The feeding box 4 provides a centralized storage space for the aggregate bodies 6 required for winding. Before the winding production begins, the operator can put multiple aggregate bodies 6 that need to be wound into the box. The aggregate body 6 of the line is put into the inner side of the feeding box 4 in one go, avoiding the operation of frequently replenishing the aggregate body 6 and improving production efficiency. The aggregate body 6 put into the feeding box 4 will be arranged vertically. When the feeding component extends, the feeding component will extend from the rectangular groove on one side of the feeding box 4, thereby pushing out the aggregate body 6 at the bottom for winding. The front baffle 5 is symmetrically arranged to limit the aggregate body 6 while making it easy to observe the quantity of aggregate body 6 in the feeding box 4, so as to facilitate timely replenishment.

[0023] like Figures 4 to 6 As shown, the feeding assembly also includes several support frames 7, which are fixedly installed on the top of the workbench 1. Telescopic cylinders 8 are fixedly installed between the inner walls of the support frames 7. The end of the telescopic cylinder 8 near the discharge box 4 is rotatably connected to the pusher plate 9. The feeding assembly also includes an expansion assembly, which is located on the side of the pusher plate 9 away from the telescopic cylinder 8. After the feeding assembly is started, the telescopic cylinder 8 will extend, thereby pushing the pusher plate 9 to move in the direction of the drive assembly. When the pusher plate 9 moves, it will drive the expansion assembly to move together. During the movement of the pusher plate 9, it will contact the bottom aggregate body 6 in the discharge box 4. At this time, the expansion assembly will enter the inside of the aggregate body 6. As the pusher plate 9 continues to move, the pusher plate 9 will push the bottom aggregate body 6 out from the inside of the discharge box 4. After the aggregate body 6 is pushed out, it will hang on the outside of the expansion assembly and move together, thereby achieving the effect of automatic feeding.

[0024] like Figure 4As shown, the diameter of the pusher plate 9 is the same as the diameter of the aggregate body 6. A limit baffle 10 is fixedly installed on the outer wall of the end of the telescopic cylinder 8 near the pusher plate 9. The limit baffle 10 is located on the side of the pusher plate 9 near the telescopic cylinder 8, and the diameter of the limit baffle 10 is the same as the diameter of the pusher plate 9. The diameter of the pusher plate 9 is the same as that of the aggregate body 6, and the pusher plate 9 is aligned with the bottom aggregate body 6. Therefore, when the pusher plate 9 passes through the inside of the discharge box 4, the pusher plate 9 can push the bottom aggregate body 6. The bottom aggregate body 6 is pushed out without affecting the other aggregate bodies 6. The diameter of the limiting baffle 10 is the same as that of the pusher plate 9. When the telescopic cylinder 8 is extended or retracted, the limiting baffle 10 will move together with the pusher plate 9. Therefore, after the pusher plate 9 passes through the discharge box 4, the limiting baffle 10 will enter the inside of the discharge box 4 to support the remaining aggregate bodies 6, so that the remaining aggregate bodies 6 will not fall down, thereby preventing the feeding component from interfering with the remaining aggregate bodies 6 and causing jamming when resetting.

[0025] like Figures 4 to 6 As shown, the expansion assembly includes a mandrel 11, which is fixedly installed at the axis of the pusher plate 9. A sliding column 12 is slidably installed on the outer wall of the mandrel 11. Several limiting grooves 13 are opened on the outer wall of the pusher plate 9. Limiting blocks 14 are slidably installed on the inner wall of each limiting groove 13. Fixing plates 15 are fixedly installed on the outer wall of each limiting block 14. A set of hinged columns 16 is fixedly installed between each fixing plate 15 and the sliding column 12. Several force-bearing plates 17 are fixedly installed on the outer wall of the sliding column 12. An elastic telescopic rod 18 is fixedly installed between each force-bearing plate 17 and the pusher plate 9. During the process of the aggregate body 6 hanging on the outside of the expansion assembly and moving with it, when the sliding column 12 contacts the drive assembly, as the expansion assembly continues to move, the drive assembly will squeeze the sliding column 12. The sliding column 12 will slide on the mandrel 11 towards the pusher plate 9 under the squeeze. At this time, the elastic telescopic rod 18 will retract. When the sliding column 12 slides, it will cause the sliding column 12 to... When the hinge column 16 rotates, each fixing plate 15 expands outward synchronously. The expanded fixing plates 15 fit against the inner wall of the aggregate body 6, thus achieving the effect of automatically fixing the aggregate body 6 from the inside. After the winding work is completed, the telescopic cylinder 8 retracts, and the pusher plate 9 drives the expansion assembly away from the drive assembly. When the expansion assembly separates from the drive assembly, the slide column 12 resets under the action of the elastic telescopic rod 18, and each fixing plate 15 retracts inward to release the fixing of the aggregate body 6. After the fixing plates 15 retract, the aggregate body 6 will be hung on the outside of the expansion assembly again. At this time, due to the retraction of the fixing plates 15, the aggregate body 6 will move down, so there will be an overlapping area between the aggregate body 6 and the fixing seat 3. During the reset of the expansion assembly, the fixing seat 3 will abut against the aggregate body 6, and the aggregate body 6 will detach from the outside of the expansion assembly, thus achieving the effect of automatic feeding.

[0026] like Figures 1 to 2 and Figure 7 As shown, the drive assembly includes a vertical plate 19, which is slidably mounted on the top of the workbench 1. A turntable 20 is provided on the side of the vertical plate 19 near the material feeding box 4, and a drive motor 21 is fixedly mounted on the side of the vertical plate 19 away from the material feeding box 4. The output shaft of the drive motor 21 passes through the vertical plate 19 and is fixedly connected to the turntable 20. The drive assembly also includes a plug-in assembly. When the sliding column 12 contacts the turntable 20, the turntable 20 will squeeze the sliding column 12 to fix the aggregate body 6. At the same time, after the sliding column 12 contacts the turntable 20, it will be... Connect the sliding column 12 to the turntable 20. When winding, fix one end of the enameled wire to the aggregate body 6 and start the drive motor 21. The drive motor 21 will drive the turntable 20 to rotate. Since the sliding column 12 is connected to the turntable 20 through the plug-in assembly, when the turntable 20 rotates, it will drive the expansion assembly and the pusher plate 9 to rotate together through the plug-in assembly. When the expansion assembly and the pusher plate 9 rotate, they will drive the aggregate body 6 to rotate. When the aggregate body 6 rotates, it will wrap the enameled wire around its outside, thereby achieving the effect of automatic winding.

[0027] like Figure 5 and Figure 7 As shown, the plug-in assembly includes a snap-fit ​​groove 22, which is located at the axis of the turntable 20 near the feeding box 4. A snap-fit ​​block 23 adapted to the snap-fit ​​groove 22 is fixedly installed at the end of the slide column 12 away from the pusher plate 9. When the slide column 12 contacts the turntable 20, the snap-fit ​​block 23 will be inserted into the inside of the snap-fit ​​groove 22. When the turntable 20 rotates, it will drive the snap-fit ​​block 23 to rotate through the snap-fit ​​groove 22. When the snap-fit ​​block 23 rotates, it will drive the expansion assembly and the pusher plate 9 to rotate, thereby providing power for the winding operation.

[0028] like Figures 1 to 2 and Figure 7 As shown, a slide groove 24 is provided on the top of the workbench 1. A sliding seat 25 is slidably installed on the inner wall of the slide groove 24. The top of the sliding seat 25 is fixedly connected to the bottom of the upright plate 19. A limit post 26 is fixedly installed on the inner wall of the slide groove 24. The outer wall of the limit post 26 is slidably connected to the inner wall of the sliding seat 25. An elastic element 27 is fixedly installed between the inner wall of the slide groove 24 and the outer wall of the sliding seat 25. The elastic element 27 is sleeved on the outside of the limit post 26. While the winding operation is being performed, the telescopic cylinder 8 will drive the pusher plate 9 and the expansion assembly to continue to move at a constant speed. The turntable 20, through the cooperation of the sliding seat 25, the limiting post 26 and the elastic element 27, can move together with the expansion assembly and keep in contact with it, thereby ensuring the normal progress of the winding operation. Through the uniform movement of the push plate 9 and the expansion assembly, the aggregate body 6 can move at a uniform speed while the winding operation is being carried out. The uniform movement of the aggregate body 6 can ensure the uniformity of the winding, keep the distance between each coil turn equal, ensure that the electrical parameters such as the inductance and resistance of the coil meet the design requirements, and improve the performance stability of the speaker.

[0029] like Figure 1 and Figure 8 As shown, a feeding plate 28 and a collection box 29 are fixedly installed on the top of the workbench 1. The outer wall of the feeding plate 28 is fixedly connected to the opening of the collection box 29. The feeding plate 28 is fixedly connected to the side of the fixed seat 3 near the turntable 20. When the aggregate body 6 that has completed the winding work is detached from the expansion component, the detached aggregate body 6 will enter the inner side of the collection box 29 along the feeding plate 28, thereby achieving the effect of automatic collection.

[0030] like Figure 1 and Figure 9 As shown, a support base 30 is fixedly installed on the top of the workbench 1, and a wire reel 31 is rotatably installed on the inner wall of the support base 30. A positioning plate 32 is fixedly installed on the top of the workbench 1, and a positioning ring 33 is fixedly installed on the top of the positioning plate 32. The positioning ring 33 is located between the wire reel 31 and the turntable 20. The wire reel 31 is used to store the enameled wire, which is the raw material for coil winding. When the device is working, the turntable 20 drives the aggregate body 6 to rotate for winding. The enameled wire is pulled out from the wire reel 31 to provide raw material for the winding work. The positioning ring 33 is located between the wire reel 31 and the turntable 20 to guide the enameled wire. During the winding process, after the enameled wire is pulled out from the wire reel 31, it can be accurately guided to the aggregate body 6 for winding.

[0031] Working Principle: During winding, the aggregate to be wound is placed inside the feeding assembly. The aggregate is vertically aligned due to the constraint of the feeding assembly. After the feeding assembly is activated, it extends towards the drive assembly. During this extension, the feeding assembly pushes out the bottommost aggregate inside the feeding assembly. The aggregate moves towards the drive assembly along with the feeding assembly. When the feeding assembly contacts the drive assembly, the drive assembly compresses it as the feeding assembly continues to move. This compression fixes the aggregate from the inside, and a connection is formed between the feeding and drive assemblies. The drive assembly then transmits power to the feeding assembly. With the aggregate fixed, the drive assembly rotates, causing the feeding assembly to rotate the aggregate. This rotation of the aggregate achieves the winding process. After winding is complete, the feeding assembly resets. During the reset process, the aggregate is... The feeding component separates from the drive component. The feeding component releases the aggregate from its fixation, and the aggregate moves downward under gravity. After moving downward, the aggregate overlaps with the unloading component. Therefore, during the reset process, the unloading component pushes the aggregate off the feeding component, thus achieving automatic unloading. After the reset is complete, the feeding component repeats the above operation for the next winding operation. In summary, this invention achieves a high degree of automation from aggregate feeding, fixing, winding to unloading. Only the aggregate needs to be fed to the unloading component, and the subsequent work is completed automatically by the device. This reduces manual operation, lowers labor costs, and avoids errors and interruptions that may be caused by manual operation, greatly improving production efficiency. After completing one winding operation, the device resets and repeats the operation, enabling continuous winding operations and achieving production continuity. This increases the product output per unit time and meets the needs of large-scale production.

[0032] The feeding box 4 provides a centralized storage space for the aggregate bodies 6 required for winding. Before the start of winding production, the operator can put multiple aggregate bodies 6 that need to be wound into the inside of the feeding box 4 at once, avoiding frequent replenishment of aggregate bodies 6 and improving production efficiency. The aggregate bodies 6 put into the feeding box 4 are arranged vertically. When the feeding component extends, it will extend from the rectangular slot on one side of the feeding box 4, thereby pushing out the aggregate body 6 at the bottom for winding. The symmetrically arranged front baffles 5 limit the movement of the aggregate bodies 6 while facilitating the feeding of aggregates in the feeding box 4. The quantity of aggregate body 6 is observed to facilitate timely replenishment. After the feeding component is activated, the telescopic cylinder 8 extends to push the pusher plate 9 towards the drive component. As the pusher plate 9 moves, it drives the expansion component to move as well. During the movement of the pusher plate 9, it will contact the bottom aggregate body 6 in the discharge box 4. At this time, the expansion component will enter the inside of the aggregate body 6. As the pusher plate 9 continues to move, it will push the bottom aggregate body 6 out of the inside of the discharge box 4. After being pushed out, the aggregate body 6 will hang on the outside of the expansion component and move with it, thereby achieving the effect of automatic feeding.

[0033] The diameter of the pusher plate 9 is the same as that of the aggregate body 6, and the pusher plate 9 is aligned with the bottom aggregate body 6. Therefore, when the pusher plate 9 passes through the inside of the discharge box 4, it can push out the bottom aggregate body 6 without affecting the rest of the aggregate bodies 6. The diameter of the limiting baffle 10 is the same as that of the pusher plate 9. When the telescopic cylinder 8 extends and retracts, the limiting baffle 10 will move together with the pusher plate 9. Therefore, after the pusher plate 9 passes through the discharge box 4, the limiting baffle 10 will enter the inside of the discharge box 4 to support the remaining aggregate bodies 6, so that the remaining aggregate bodies 6 will not fall, thereby preventing the feeding component from interfering with the remaining aggregate bodies 6 and causing jamming when resetting.

[0034] As the aggregate body 6 hangs on the outside of the expansion assembly and moves with it, when the sliding column 12 contacts the drive assembly, the drive assembly will squeeze the sliding column 12 as the expansion assembly continues to move. The sliding column 12, under pressure, will slide on the mandrel 11 towards the push plate 9. At this time, the elastic telescopic rod 18 will retract. When the sliding column 12 slides, it will cause the hinge column 16 to rotate. When the hinge column 16 rotates, it will cause each fixing plate 15 to expand outward synchronously. The expanded fixing plate 15 will fit against the inner wall of the aggregate body 6, thereby achieving the effect of automatically fixing the aggregate body 6 from the inside. The coil 31 is used to store the enameled wire, which is the raw material for coil winding. When the device is working, the turntable 20 drives the aggregate body 6 to rotate for winding. The enameled wire is pulled out from the coil 31 to provide raw material for the winding work. The positioning ring 33 is located between the coil 31 and the turntable 2. Between 0 and 0, the enameled wire is guided. During the winding process, after the enameled wire is pulled out from the wire reel 31, it can be accurately guided to the aggregate body 6 for winding. When the winding work is completed, the telescopic cylinder 8 retracts, and the pusher plate 9 will drive the expansion component away from the drive component. When the expansion component is separated from the drive component, the slide column 12 will be reset under the action of the elastic telescopic rod 18. Each fixing plate 15 will retract inward to release the fixation of the aggregate body 6. After the fixing plate 15 retracts, the aggregate body 6 will be hung on the outside of the expansion component again. At this time, due to the retraction of the fixing plate 15, the aggregate body 6 will move down. Therefore, the aggregate body 6 will have an overlapping area with the fixing seat 3. During the reset of the expansion component, the fixing seat 3 will abut against the aggregate body 6, and the aggregate body 6 will detach from the outside of the expansion component, thereby achieving the effect of automatic feeding.

[0035] When the sliding column 12 contacts the turntable 20, the turntable 20 will press the sliding column 12 to fix the aggregate body 6. At the same time, after the sliding column 12 contacts the turntable 20, the connecting component will connect the sliding column 12 and the turntable 20. During the winding operation, one end of the enameled wire is fixed to the aggregate body 6, and the drive motor 21 is started. The drive motor 21 will drive the turntable 20 to rotate. Since the sliding column 12 is connected to the turntable 20 through the connecting component, the rotation of the turntable 20 will cause the pull of the rotating column to be driven by the connecting component. The expansion assembly and the pusher plate 9 rotate together. When the expansion assembly and the pusher plate 9 rotate, they will drive the aggregate body 6 to rotate. When the aggregate body 6 rotates, it will wrap the enameled wire around its outside, thereby achieving the effect of automatic winding. When the sliding column 12 contacts the turntable 20, the locking block 23 will be inserted into the inside of the locking groove 22. When the turntable 20 rotates, it will drive the locking block 23 to rotate through the locking groove 22. When the locking block 23 rotates, it will drive the expansion assembly and the pusher plate 9 to rotate, thereby providing power for the winding operation.

[0036] While the winding process is underway, the telescopic cylinder 8 drives the pusher plate 9 and the expansion assembly to continue moving at a constant speed. The turntable 20, through the cooperation of the sliding seat 25, the limiting post 26, and the elastic element 27, can move along with the expansion assembly and remain in contact with it, thereby ensuring the normal progress of the winding process. The constant speed movement of the pusher plate 9 and the expansion assembly allows the aggregate body 6 to move at a constant speed while the winding process is underway. This constant speed movement of the aggregate body 6 ensures the uniformity of the winding, keeps the distance between each coil turn equal, and ensures that the electrical parameters such as the inductance and resistance of the coil meet the design requirements, thereby improving the performance stability of the speaker. After the aggregate body 6 has completed the winding process and detaches from the expansion assembly, the detached aggregate body 6 will enter the inner side of the collection box 29 along the feed plate 28, thereby achieving the effect of automatic collection.
