Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and in particular to a winding device for a loudspeaker coil. Background Technology

[0002] The coil outside the magnetic ring of a loudspeaker is the voice coil. The voice coil is an important component of a loudspeaker, usually made of enameled wire. It is located in the magnetic field generated by the magnetic ring. When audio current passes through the voice coil, according to the Ampere force principle, the voice coil will be subjected to a magnetic force. Since the audio current is an alternating current that changes with the audio signal, the magnitude and direction of the magnetic force on the voice coil will also change continuously with time, thus causing the voice coil to vibrate.

[0003] In existing ferrite coil winding equipment, after clamping the ferrite coil, it is generally clamped directly at both ends. However, during the winding process, it is impossible to stabilize the ferrite coil from multiple directions. As a result, when subjected to external forces during winding, such as the tension of the enameled wire during winding and the vibration generated by the operation of the winding equipment, the ferrite coil is difficult to maintain stability. This leads to the ferrite coil being prone to shaking and displacement. This not only causes uneven winding and affects the quality of the voice coil, but may also cause winding errors in the enameled wire, increasing the defect rate. Utility Model Content

[0004] The purpose of this invention is to provide a winding device for a speaker coil, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A speaker coil winding device includes a base frame, on which a controller is fixedly mounted. A feeding platform is also fixedly mounted on the base frame. A loading mechanism is fixedly mounted on the base frame behind the feeding platform. A second slide is fixedly mounted on the base frame near the controller. A wire feeding mechanism is fixedly mounted on the second slide. A shaft platform is fixedly mounted on the base frame between the feeding platform and the second slide. First slides are fixedly mounted on the base frame at both the front and rear sides of the shaft platform, and the two first slides are... A winding power output mechanism is fixedly installed, and the feeding platform, loading mechanism, wire feeding mechanism, second slide, first slide, and winding power output mechanism are electrically connected to the controller via connecting cables.

[0010] As a further preferred embodiment of this utility model, a limiting groove is provided on the outer side of the mounting base.

[0011] As a further preferred embodiment of this utility model, the countersunk hole is internally threaded with a first limiting ring.

This causes one end of the force-bearing rod to be pressed and supported on the inner side of the magnetic ring, thus enabling the clamping and fixing of magnetic rings of different diameters.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5As shown, the present invention provides a speaker coil winding device, including a base frame 1, a controller 2 fixedly mounted on the base frame 1, a feeding platform 3 fixedly mounted on the base frame 1, a loading mechanism 4 fixedly mounted on the base frame 1 behind the feeding platform 3, a second slide 28 fixedly mounted on the base frame 1 near the controller 2, a wire feeding mechanism 5 fixedly mounted on the second slide 28, a shaft platform 6 fixedly mounted on the base frame 1 between the feeding platform 3 and the second slide 28, and first slide platforms 7 fixedly mounted on the base frame 1 at both the front and rear sides of the shaft platform 6, with the two first slide platforms 7 respectively... A winding power output mechanism 8 is fixedly installed, and the feeding platform 3, the loading mechanism 4, the wire feeding mechanism 5, the second slide 28, the first slide 7, and the winding power output mechanism 8 are electrically connected to the controller 2 via connecting cables. A rotating shaft 9 is fixedly installed at the output end of the winding power output mechanism 8. One end of the rotating shaft 9 passes through the shaft base 6 and extends into the shaft base 6 and is fixedly installed with a mounting base 10. A conical block 11 is movably installed in the mounting base 10. A plug ring 12 is movably installed on one side of the mounting base 10. Multiple countersunk holes 13 are opened on the inner side of the plug ring 12, and a force-bearing rod 14 is movably installed in the countersunk holes 13.

[0023] like Figures 1-2 As shown, the base frame 1 is fixedly installed on the external workbench, and the feed tray 15 is fixedly installed inside the shaft plate 6, with the feed tray 15 located below the two mounting seats 10.

[0024] like Figure 3 As shown, a mounting groove 16 is provided on the inner side of the mounting base 10. A bearing 17 is fixedly installed in the middle of one side of the mounting groove 16. A fixed shaft 19 is rotatably installed in the bearing 17. An adjusting screw 18 is fixedly installed at one end of the fixed shaft 19. A screw hole 20 is provided in the middle of the conical block 11. The screw hole 20 is threadedly connected to the adjusting screw 18. Multiple sliders on the outer side of the conical block 11 are slidably connected in the corresponding sliding grooves on the inner side of the mounting groove 16. After the conical block 11 is inserted into the mounting groove 16, the horizontal position of the conical block 11 can be adjusted by rotating the adjusting screw 18 in the screw hole 20, thereby facilitating the adjustment of the movement process of the force-bearing rod 14. A limit groove 21 is provided on the outer side of the mounting base 10.

[0025] like Figures 3-5As shown, a first limiting ring 22 is threaded into the countersunk hole 13. The first limiting ring 22 facilitates the assembly of the force-bearing rod 14 into the countersunk hole 13 and limits the movement of the force-bearing rod 14 installed in the countersunk hole 13. A fixing ring 23 is fixedly installed at one end of the force-bearing rod 14, and a push rod 24 is fixedly installed at the end of the fixing ring 23 opposite to the force-bearing rod 14. The end of the push rod 24 away from the fixing ring 23 is coated with a rubber layer, and one end of the force-bearing rod 14 is inserted into the countersunk hole 13 through the fixing ring 23. A compression spring 25 is fitted onto the push rod 24 located between the fixing ring 23 and the first limiting ring 22. The force-bearing rod 14 is installed through the fixing ring 23... After the countersunk hole 13 is inserted, the compression spring 25 and the conical block 11 can be used to clamp the magnetic ring with the top plate 29. The insertion ring 12 is inserted into the magnetic ring, and the force rod 14 moves one end of the top rod 24 to abut against the inner side of the magnetic ring, which can effectively improve the stability of the magnetic ring when winding. The insertion ring 12 is fixedly installed on one side of the mounting base 10. The top plate 29 is fixedly installed on the outside of the connection shell 26. The second limiting ring 27 is fixedly installed on the inside of the connection shell 26. The side of the connection shell 26 away from the insertion ring 12 is inserted and installed on the outside of the mounting base 10 through the second limiting ring 27. The second limiting ring 27 is slidably connected in the limiting groove 21.

[0026] It should be noted that this utility model is a winding device for a loudspeaker coil. When the feeding platform 3 transports the magnetic ring assembly to the area below the clamp of the loading mechanism 4, the clamp of the loading mechanism 4 picks up the magnetic ring and moves it between the two insertion rings 12. Then, the two first slides 7 respectively drive the upper winding power output mechanism 8 to move towards the shaft platform 6, so that the output ends of the two winding power output mechanisms 8 respectively drive the rotating shaft 9 to move within the shaft platform 6. This causes the two rotating shafts 9 to drive the mounting base 10 at one end to move relative to the insertion ring 12, so that the two insertion rings 12 are respectively inserted into the interior of the magnetic ring, and the two ends of the magnetic ring respectively abut against one side of the corresponding top plate 29. Step by step, after the top plate 29 is subjected to pressure, the insertion ring 12 moves towards the mounting base 10. Then, the insertion ring 12 moves on one side of the mounting base 10 through the connecting shell 26 on one side and the second limiting ring 27, and causes the insertion ring 12 to drive the three countersunk holes 13 to move synchronously towards the mounting base 10. This causes one end of the three force rods 14 to abut against the outside of the conical block 11. Through the slope angle difference of the outside of the conical block 11, they move into the countersunk holes 13, thereby causing the force rods 14 to push the corresponding push rods 24 out of the countersunk holes 13, and causing one end of the push rods 24 to abut against the inside of the magnetic ring, thereby achieving stable clamping of the magnetic ring. The two winding power output mechanisms 8 drive the corresponding rotating shafts 9 to rotate, thereby driving the magnetic ring to rotate, thus cooperating with the wire feeding mechanism 5 to perform the winding action of the magnetic ring.

[0027] When it is necessary to adjust the ejection process of the push rod 24 according to different batches of magnetic rings of different diameters, simply rotate the adjusting screw 18 with a tool. The adjusting screw 18 rotates around the pivot 9 at one end, causing the conical block 11 to move within the mounting groove 16. This adjusts the contact position between the end of the force rod 14 and the outer side of the conical block 11 after the insertion ring 12 contacts the mounting base 10, thereby lifting the extrusion process of the force rod 14 and adjusting the ejection process of the push rod 24. This allows for quick adjustment of the ejection process of the push rod 24 for magnetic rings of different diameters.
