[0003] For example, the Chinese utility model patent authorization announcement number CN222192540U discloses a speaker assembly positioning coil mold. This utility model can perform positioning operations during coil assembly, making it easy for the coil to accurately enter the space surrounding the speaker magnetic poles, and can also be easily cleaned before assembly.

[0004] However, in actual use, the aforementioned patent requires selecting a suitable mounting sleeve based on the inner diameter of the coil and screwing it onto the cylinder. This necessitates having a complete set of mounting sleeves of different specifications available in advance. This not only increases the number of system components and production costs but also brings the inconvenience of frequent replacements and finding matching parts during operation, severely reducing installation efficiency and ease of use. Utility Model Content

[0009] Furthermore, a telescopic rod is connected between the side wall of the clamping plate and the vertical plate, which improves the stability of the clamping plate during movement and prevents swaying.

[0010] Furthermore, the clamping plate has a slot on its side wall, and a card plate is attached to the inside of the slot. One side of the card plate is connected to an electrostatic adsorption sticker, and the other side is connected to a handle. The electrostatic adsorption sticker can adsorb dust in the gaps of the magnetic poles, and the card plate is detachable for easy cleaning.

[0011] Furthermore, a motor is connected to the end of the robotic arm body, and the output end of the motor is connected to the disk, which can realize the rotation of the clamping mechanism to adapt to the embedding requirements of different angles.

[0012] Furthermore, the upper surface of the disk is connected to multiple evenly distributed guide rods, and the end of the robotic arm body is provided with a sliding groove on the outside of the motor to slide in connection with the guide rods, so as to ensure the stability and accuracy of the disk rotation.

[0013] Furthermore, the retractable hose is a corrugated pipe, and a quick connector is provided at the connection point with the clamping plate for easy maintenance and replacement.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0023] Example Reference Figure 1 The present embodiment provides a horn moving coil embedding device, including a robotic arm body 1. A disk 2 is provided at the end of the robotic arm body 1. Four evenly distributed horizontal plates 3 are connected to the outer side of the disk 2. A vertical plate 4 is connected to the end of the horizontal plate 3. A cylinder 5 is connected to the outer wall of the vertical plate 4. A clamping plate 6 is provided on the side of the vertical plate 4 away from the cylinder 5. The output of the cylinder 5 passes through the vertical plate 4 and is connected to the side wall of the clamping plate 6.

[0024] In this embodiment, the robotic arm body 1 moves to a predetermined position above the moving coil under the command of the control system. Subsequently, the cylinder 5 actuates, its output shaft pushing the clamping plate 6 towards the moving coil, causing the clamping plate 6 to contact and apply pressure to the outer or inner wall of the moving coil, thereby completing the mechanical clamping of the moving coil. After clamping, the robotic arm body 1 carries the moving coil precisely to above the horn magnetic gap and embeds the moving coil into the designated position. After the embedding action is completed, the cylinder 5 retracts, causing the clamping plate 6 to release the moving coil, and the robotic arm body 1 resets, ready to perform the next operation.

[0025] Reference Figure 3 , Figure 5 The clamping plate 6 has a hollow interior and air holes 7 on both sides. An air pump 8 is connected to one side of the upper surface of the horizontal plate 3. A retractable hose 9 is connected between the input end of the air pump 8 and the clamping plate 6.

[0026] In this embodiment, the suction pump 8 is activated, drawing air from the cavity of the clamping plate 6 through the retractable hose 9, creating a negative pressure inside. External air flows in through the air holes 7 on both sides of the clamping plate 6, thereby generating a strong adsorption force on the surface of the moving coil covering the air holes 7. This pneumatic adsorption process, in conjunction with the mechanical clamping of the cylinder 5, achieves double fixation of the moving coil, greatly enhancing the reliability and stability of the clamping and preventing slippage during high-speed movement or precise positioning.

[0027] Reference Figure 3A telescopic rod 10 is connected between the side wall of the clamping plate 6 and the vertical plate 4.

[0028] In this embodiment, when the cylinder 5 drives the clamping plate 6 to extend or retract, the telescopic rod 10 connecting the clamping plate 6 and the vertical plate 4 extends and retracts synchronously. This telescopic rod 10 provides additional radial support for the core clamping plate 6, effectively suppressing any swaying or deflection that may occur during movement, ensuring that the movement trajectory of the clamping plate 6 is strictly linear, thereby improving the centering of the clamping and the accuracy and repeatability of the entire embedding process.

[0029] Reference Figure 3 , Figure 4 The clamping plate 6 has a slot 11 on its side wall. The slot 11 has a card plate 12 inside it. One side of the card plate 12 is connected to an electrostatic adsorption sticker 13, and the other side is connected to a handle 14.

[0030] In this embodiment, before the moving coil is inserted, this structure can be used for cleaning. The suction pump 8 is activated, and airflow passes through the air holes 7 of the clamping plate 6 to remove most of the dust particles from the magnetic gap. Simultaneously, the electrostatic adsorption sticker 13, located on the clamping plate 12, further adsorbs residual fine dust using electrostatic effects, ensuring the cleanliness of the insertion area. After cleaning or when the electrostatic adsorption sticker 13 needs to be replaced, the operator can pull the handle 14 to remove the clamping plate 12 from the slot 11 of the clamping plate 6, and clean or replace the electrostatic adsorption sticker 13, making maintenance convenient.

[0031] Reference Figure 3 The robotic arm body 1 is connected to a motor 15 at one end, and the output end of the motor 15 is connected to the disk 2.

[0032] In this embodiment, the motor 15 starts after receiving a control signal, and its output shaft drives the disk 2 fixed to it to rotate. The disk 2 drives the four horizontal plates 3, vertical plates 4, cylinders 5, clamping plates 6, and telescopic rods 10, which are evenly distributed around its periphery, to rotate together around the axis of the motor 15. This function allows the device to fine-tune the circumferential angle of the moving ring without readjusting the overall orientation of the robotic arm body 1, so as to quickly align it with the specific orientation of the horn magnetic gap, greatly enhancing the adaptability and operational flexibility of the device to different installation angle requirements.

[0033] Reference Figure 2 The upper surface of the disc 2 is connected with a plurality of evenly distributed guide rods 16, and the end of the robotic arm body 1 is provided with a sliding groove 17 located outside the motor 15, which is slidably connected to the guide rods 16.

[0034] In this embodiment, during the rotation of the disk 2 driven by the motor 15, the guide rod 16 fixed to the upper surface of the disk 2 slides within the groove 17 at the end of the robotic arm body 1. The guide rod 16 and the groove 17 form a precise sliding guide pair, providing radial support and circumferential guidance for the rotational movement of the disk 2, effectively preventing radial runout or tilting of the disk 2 during rotation, and ensuring the smoothness of the rotation process and the accuracy of angular positioning.

[0035] Reference Figure 5 The retractable hose 9 is a corrugated pipe, and a quick connector 18 is provided at the connection between it and the clamping plate 6.

[0036] In this embodiment, the retractable hose 9 adopts a corrugated structure, giving it excellent telescopic and bending performance. When the cylinder 5 pushes the clamping plate 6 to reciprocate or the motor 15 drives the disc 2 to rotate, the corrugated retractable hose 9 can freely extend, compress, or bend accordingly, always ensuring the unobstructed and sealed air passage connection between the suction pump 8 and the clamping plate 6. The quick connector 18 provided at its connection point facilitates daily maintenance, disassembly, and replacement of the equipment, simplifying the operation process.

[0037] Reference Figure 4 The electrostatic adsorption sticker 13 has a detachable structure and its surface is coated with an anti-stick coating.

[0038] In this embodiment, the electrostatic adsorption patch 13 is mounted on the card plate 12 via its detachable structure. When excessive dust accumulates on the surface of the electrostatic adsorption patch 13 and its adsorption capacity decreases, the operator can remove it from the card plate 12 for cleaning or directly replace it with a new adsorption patch. Its non-stick coating helps dust to detach more easily from the adsorption patch during cleaning, while also preventing excessive adhesion between the adsorption patch and the card plate 12 or dust, extending its service life and maintaining high-efficiency cleaning performance.

[0039] A horn assembly system includes a conveyor belt mechanism for conveying horn components and a moving coil.

[0040] In this embodiment, the conveyor belt mechanism is responsible for continuously transporting the speaker components to be assembled, such as the magnetic circuit system and the moving coil, to the workstation in a rhythmic manner. The robotic arm 1, located above the workstation, precisely grasps the moving coil from the conveyor belt and performs the embedding operation. After completion, the robotic arm returns the assembled speaker product to the conveyor belt, which then transports it to the next workstation. Throughout the entire process, the embedding device and the conveyor belt mechanism work collaboratively under the control system's scheduling, forming a highly efficient automated speaker assembly production line.
