[0002] The voice coil is directly defined as a coil through which current flows in a loudspeaker, and it is an important component of the mechanical wave system of an electrodynamic loudspeaker.

[0003] Chinese patent document CN206698435U discloses a collection device for automatic voice coil winding. When the voice coil is pushed onto the receiving rod by the winding die head, the piston rod of the cylinder moves downward with the pressure plate until the pressure plate presses down on the voice coil. After the winding die head retracts, the pressure plate moves upward with the cylinder, disengaging from the voice coil and returning to its original position. After the receiving rod collects a certain number of voice coils, a rotary motor drives the collection turntable to rotate, moving the next receiving rod to the collection station to continue collecting voice coils.

[0004] In the above scheme, when collecting voice coils by receiving rod, multiple voice coils are sequentially connected to the receiving rod. During use, it is impossible to quickly discharge the voice coils on the receiving rod, which affects the voice coil discharge efficiency. Utility Model Content

[0030] Example 1

[0031] like Figure 1-4 As shown, the present invention proposes a take-up device for automatic voice coil winding, comprising a connecting shell 1, a ring plate 3, a mounting bracket 15, and a drive assembly;

[0032] The connecting shell 1 is rotatably mounted on the top of the mounting bracket 15. The connecting shell 1 rotates on the mounting bracket 15 via a motor (not shown in the figure). The outer circular surface of the connecting shell 1 is provided with multiple connecting tubes 2 for placing the voice coil in the use state.

[0033] The ring plate 3 is sleeved on the outside of the connecting pipe 2, and the inner side is fitted to the outside of the connecting pipe 2 to make the sliding connection between the ring plate 3 and the connecting pipe 2 more stable. The side of the ring plate 3 and the inner side of the connecting pipe 2 are provided with an adjustment component for moving the ring plate 3 along the length of the connecting pipe 2 on the outside of the connecting pipe 2 during use.

[0034] The drive assembly is located at the top of the mounting bracket 15 and inside the connecting shell 1 on one side and connected to the adjustment assembly. It is used to drive the adjustment assembly to operate during material discharge, thereby causing the adjustment assembly to move the ring plate 3 on the connecting pipe 2.

[0035] In this embodiment, the motor drives the connecting shell 1 to rotate on the mounting bracket 15, causing the connecting shell 1 to move the connecting tube 2 to the voice coil receiving point. The connecting tube 2 receives the voice coils, and after collecting a certain number of voice coils, the connecting shell 1 drives the connecting tube 2 to rotate, moving the next connecting tube 2 to the receiving point to continue collecting voice coils. The collected connecting tube 2 is then moved to the discharge point, causing the connecting tube 2 to engage with the adjustment component and the drive component. The drive component is then activated, driving the adjustment component to operate. The adjustment component drives the ring plate 3 to move along the length of the connecting tube 2 on the outside of the connecting tube 2, thereby moving the ring plate 3 towards the end of the connecting tube 2 for voice coil discharge. This facilitates voice coil discharge. Simultaneously, the connecting shell 1 moves multiple connecting tubes 2 sequentially to the discharge point, causing each connecting tube 2 to engage with the adjustment component and the drive component, thus discharging the voice coils on the multiple connecting tubes 2 and improving voice coil discharge efficiency.

[0036] Example 2

[0037] like Figure 3-4 As shown, the present invention proposes an automatic voice coil winding take-up device. Compared with the first embodiment, the difference in this embodiment is that the adjustment component includes a first bevel gear 7, a lead screw 8, a connecting rod 10, and a nut 12.

[0038] The lead screw 8 is rotatably mounted inside the connecting pipe 2 and one end extends to the inside of the connecting shell 1;

[0039] Nut 12 is sleeved on the outside of screw 8 and located on the inside of connecting pipe 2;

[0040] There are multiple connecting rods 10, which are arranged at equal angles on the outside of the nut 12 and extend to the outside of the connecting tube 2 to connect with the ring plate 3;

[0041] The first bevel gear 7 is installed at the end of the lead screw 8 and is located inside the connecting housing 1 and connected to the drive assembly.

[0042] In an optional embodiment, a sleeve 4 is provided on the side of the ring plate 3. The sleeve 4 is sleeved on the outside of the connecting rod 10 and is used to limit the connection between the ring plate 3 and the connecting rod 10 during use, so that the connecting rod 10 drives the ring plate 3 to reciprocate on the outside of the connecting pipe 2 through the sleeve 4.

[0043] In an optional embodiment, a waist-shaped hole 5 is provided on the outer circular surface of the connecting tube 2 along the length direction. The connecting rod 10 is located in the waist-shaped hole 5 and extends to the outside of the connecting tube 2. It is used to enable the lead screw 8 to drive the connecting rod 10 to move in the waist-shaped hole 5 along the length direction of the connecting tube 2 through the nut 12, so that the movement of the connecting rod 10 is stable and avoids obstruction.

[0044] In this embodiment, the first bevel gear 7 meshes with the drive assembly, causing the drive assembly to drive the lead screw 8 to rotate on the connecting tube 2 via the first bevel gear 7. The connecting rod 10 limits the rotation of the nut 12 in the waist-shaped hole 5, causing the lead screw 8 to drive the nut 12 to move along the length of the lead screw 8. In turn, the nut 12 drives the connecting rod 10 in the waist-shaped hole 5 to drive the ring plate 3 to move from the outside of the connecting tube 2 to the end of the connecting tube 2 via the sleeve 4, so that the voice coil on the connecting tube 2 can be discharged. At the same time, the drive assembly is rotated in the reverse direction, so that the ring plate 3 is reset, and the voice coil receiving work can be performed on the connecting tube 2 again.

[0045] Example 3

[0046] like Figure 4As shown, this utility model proposes an automatic voice coil winding take-up device. Compared with embodiment one, the difference in this embodiment is that the bottom end of the sleeve 4 is provided with a threaded joint 13, and the outer side of the nut 12 is provided with a threaded groove 14. When the connecting rod 10 and the nut 12 are installed together, the threaded joint 13 is fitted and accommodated in the threaded groove 14. The top end of the connecting rod 10 is provided with a rotating groove 11, which is used to detachably connect the connecting rod 10 and the nut 12 during use, making the installation and maintenance of the connecting rod 10 and the nut 12 more convenient. In order to prevent the nut 12 from causing frictional rotation between the connecting rod 10 and the inner wall of the waist-shaped hole 5, a sliding rod can be provided on the inner side of the connecting tube 2 during use. The sliding rod is arranged through one end of the nut 12, or a sliding strip can be provided on the inner side of the connecting tube 2 along the length of the connecting tube 2. The sliding strip is slidably connected to the nut 12, so that the nut 12 slides on the sliding rod or sliding strip and its rotation is limited. This is not shown in the prior art figures.

[0047] In this embodiment, the threaded joint 13 is connected to the threaded groove 14 through the rotating groove 11 by inserting the connecting rod 10 into the inner side of the sleeve 4, so that the connecting rod 10 and the nut 12 can be detachably connected.

[0048] Example 4

[0049] like Figure 2 As shown, the present invention proposes an automatic voice coil winding take-up device. Compared with the first embodiment, the difference in this embodiment is that the driving component includes a motor 6 and a second bevel gear 9.

[0050] Motor 6 is mounted on the top of mounting bracket 15;

[0051] There are two second bevel gears 9. One of the two second bevel gears 9 is mounted on the output shaft of the motor 6, and the other second bevel gear 9 is rotatably mounted on the top of the mounting bracket 15 and meshes with the first bevel gear 7 and the second bevel gear 9 on the output shaft of the motor 6.

[0052] In this embodiment, two second bevel gears 9 mesh with each other, and the connecting shell 1 drives the first bevel gear 7 to mesh with the second bevel gear 9. At the same time, the motor 6 is started to rotate forward or in reverse to drive the second bevel gear 9 to rotate, thereby causing the second bevel gear 9 to drive the first bevel gear 7 to rotate, so that the first bevel gear 7 rotates the lead screw 8 in the connecting tube 2.

[0053] In this invention, a motor drives the connecting shell 1 to rotate on the mounting bracket 15, causing the connecting shell 1 to move the connecting tube 2 to the voice coil receiving area. The connecting tube 2 receives the voice coils, and after collecting a certain number of voice coils, the connecting shell 1 rotates the connecting tube 2 to the receiving area to continue collecting voice coils. The collected connecting tube 2 is then moved to the discharge area, where the first bevel gear 7 meshes with the second bevel gear 9. Simultaneously, the motor 6 is started to rotate forward or reverse, driving the second bevel gear 9 to rotate, thereby causing the second bevel gear 9 to drive the first bevel gear 9. The rotation of wheel 7 causes the first bevel gear 7 to rotate the lead screw 8 in the connecting tube 2. At the same time, the lead screw 8 drives the connecting rod 10 to move along the length of the connecting tube 2 in the waist-shaped hole 5 through the nut 12. This causes the connecting rod 10 to drive the ring plate 3 to move synchronously through the sleeve 4. The ring plate 3 discharges the voice coils on the connecting tube 2. At the same time, the motor 6 is rotated in the opposite direction, causing the ring plate 3 to reset. The connecting shell 1 moves multiple connecting tubes 2 sequentially to the discharge point, and the ring plate 3 moves back and forth on the connecting tubes 2, thus discharging the voice coils on the multiple connecting tubes 2 and improving the voice coil discharge efficiency.

[0054] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
