[0002] As a device that converts electrical signals into sound signals, loudspeakers play a crucial role in modern audio systems. The voice coil, as one of the core components of a loudspeaker, directly affects the performance of the loudspeaker due to the quality of its winding.

[0003] In current speaker voice coil winding processes, although equipment has improved winding efficiency to some extent, it lacks precise control over the feeding position. During the winding process, inaccurate feeding of the voice coil wire can easily lead to problems such as wire accumulation and crossing, affecting the quality of the voice coil. Furthermore, the winding components of these devices are usually only compatible with a single size of voice coil. When it is necessary to produce voice coils of different sizes, it is necessary to replace the corresponding components and perform complex adjustments, which increases production costs and production cycle.

[0004] Therefore, industry professionals have developed an auxiliary winding device for speaker voice coils to solve these problems and improve the production quality and efficiency of speaker voice coils. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary winding device for speaker voice coils to solve the technical problems of insufficient precise control of the feeding position and limited compatibility of winding components in existing speaker voice coil winding equipment, which leads to poor voice coil quality, high production costs, and long production cycles.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1:

[0023] Combination Figure 1-4The illustrated auxiliary winding device for a loudspeaker voice coil consists of several precise and collaborative parts. First, there is the device frame 1, which serves as the basic support structure for the entire device. Made of high-strength metal, it boasts excellent stability and durability, ensuring stable operation even in complex working environments. Above the device frame 1 is a feeding and translation mechanism 2, on which a feeding roller 3 is rotatably mounted. Driven by the feeding and translation mechanism 2, the feeding roller 3 achieves precise feeding position control. A raised platform 4 is positioned above the device frame 1 on one side of the feeding and translation mechanism 2, its function being to support subsequent related components. The component is raised to a suitable working height. A gearbox 5 is installed above the raised platform 4. It is adjusted and allocated according to a precise ratio to meet the speed and torque requirements of different winding processes. One end of the gearbox 5 is connected to the winding motor 6. The winding motor 6 serves as a power source, and its speed can be precisely adjusted within a wide range. It can provide a stable and suitable speed according to the different specifications of the voice coil and the specific requirements of the winding. The other end of the gearbox 5 drives the winding assembly 7. The winding assembly 7 can be adapted to the winding of voice coils of different specifications. The wire end clamp 8 is set on the winding assembly 7 to firmly clamp the starting end of the voice coil wire, ensuring the smooth progress of the winding work.

[0024] In this embodiment, the feeding translation mechanism 2 mainly consists of a feeding translation body 201 as the basic load-bearing component. This body is meticulously crafted from high-strength aluminum alloy material, which is sturdy, durable, and possesses excellent mechanical properties. A guide rail 202 is precisely installed on the upper surface of the feeding translation body 201. The guide rail 202 is made of specially customized alloy steel, possessing extremely high hardness and wear resistance. A guide slider 203 is fitted onto the guide rail 202, and the clearance between the guide slider 203 and the guide rail 202 is strictly controlled within a very small tolerance range, ensuring the stability of the subsequent feeding roller shaft 3 during translation. Bearing seats 204 are symmetrically distributed above both sides of the feeding translation body 201. Bearing seats 204 are equipped with bearings inside. Two sets of bearing seats 204... A threaded rod 205 is rotatably mounted between bearings 4. A feeding translation motor 206 is installed at one of the bearing platforms 204, which is responsible for driving the rotation of the threaded rod 205. A ball nut seat 207 is fitted on the threaded rod 205. The ball nut seat 207 is fixedly connected to the guide slider 203. In the voice coil production process, this stable and precise connection allows the ball nut seat 207 to move linearly under the drive of the threaded rod 205, thereby achieving precise control of the position of the feeding roller shaft 3. The precise movement of the feeding roller shaft 3 is crucial for the uniform feeding of the voice coil wire. Only by ensuring the accuracy of the feeding position can the quality of the voice coil winding be ensured, thereby improving the overall performance of the loudspeaker. The feeding roller shaft 3 is mounted on the ball nut seat 207.

[0025] In this embodiment, the ball nut seat 207 has an extended rod 9 securely mounted on its side wall near the raised platform 4. A guide coil 10 is mounted on the top of the extended rod 9. The guide coil 10 is made of high-quality ceramic material. This is because ceramic material has a low coefficient of friction and good wear resistance, making it particularly suitable for voice coil winding, a work scenario that requires extremely high wire protection and guiding accuracy. The guide coil 10 consistently plays its guiding role on the voice coil wire during the feeding process, helping to achieve efficient and high-quality voice coil winding operations and providing a solid guarantee for the production quality of the speaker voice coil.

[0026] In this embodiment, the winding assembly 7 is the core component in the speaker voice coil auxiliary winding device for achieving different specifications of voice coil winding. It includes a power source expansion cylinder 701, a support kit 702 firmly fixed to the side wall of the expansion cylinder 701, and a drive kit 703 provided at the end of the expansion cylinder 701. Several sets of first extension arms 704 are evenly rotatably arranged on the outer wall of the support kit 702. Similarly, several sets of second extension arms 705 are rotatably arranged on the outer wall of the drive kit 703. The number of second extension arms 705 matches that of the first extension arms 704, and the first and second extension arms 704 are alternately rotatably arranged. This ingenious layout allows for precise winding of different specifications of voice coils in the expansion cylinder 701. When the telescopic rod of cylinder 701 extends or retracts, the two sets of extended arms can move in tandem, forming an adjustable linkage structure. When the telescopic rod of expansion cylinder 701 extends, the drive assembly 703 moves forward accordingly, causing the second extended arm 705 to swing outward. Due to the staggered connection of the first extended arm 704 and the second extended arm 705, the first extended arm 704 will also rotate outward accordingly. This coordinated movement causes the expansion plate 706 installed at the ends of the first extended arm 704 and the second extended arm 705 to gradually expand outward. Conversely, when the telescopic rod retracts, the expansion plate 706 contracts inward. By precisely controlling the extension and retraction of expansion cylinder 701, the expansion and contraction amplitude of expansion plate 706 can be precisely adjusted, thereby adapting to the production of voice coils with different diameter specifications. The movable part 707 is a key component that ensures the smooth operation of the entire linkage structure. The movable part 707 is usually designed as an inwardly open slide groove and is connected to the end of the second extension arm 705, so that it can slide freely in the slide groove, providing the necessary displacement space for the second extension arm 705, avoiding motion interference, and ensuring the coordinated and stable movement of the entire winding assembly 7. The wire end clamp 8 is located on the outer wall of one of the expansion plates 706.

[0027] In this embodiment, the wire end clamp 8 is a key component in the speaker voice coil auxiliary winding device that ensures the stability of the starting end of the winding. It includes a hollow wire end clamping body 801, and a support plate 802 is horizontally arranged between the inner walls above the wire end clamping body 801. A locking bolt 803 is installed on the support plate 802. When it is necessary to fix the voice coil wire, the operator first puts the starting end of the voice coil wire into the hollow part of the wire end clamping body 801, and then rotates the locking bolt 803 clockwise. Due to the thread, the wire end clamping body clamps the wire end clamping body. When the locking bolt 803 is in use, it will gradually move downwards. As the locking bolt 803 moves downwards, its end will gradually press against the voice coil wire, firmly fixing the voice coil wire between the bottom of the hollow part and the end of the locking bolt 803. During this process, the operator can appropriately control the tightening force of the locking bolt 803 according to the material and thickness of the voice coil wire. When the winding work is completed and the voice coil needs to be removed, the operator only needs to rotate the locking bolt 803 counterclockwise to move it upwards and release the pressure on the voice coil wire.
