[0023] like Figures 1 to 6 The speaker wire removal device shown includes a wire take-up box 1, a wire clamping mechanism 2, a wire brushing mechanism 3, and a negative pressure adsorption mechanism 4, as detailed below. Figures 1 to 3As shown in the embodiment of this utility model, the top of the take-up box 1 is provided with a cable inlet 11, such as... Figure 1 As shown, the inlet 11 is the entrance of the wire end. In the actual manufacturing process, the take-up box 1 can be made of sheet metal and sealed by welding, which can improve the adsorption force when it is adsorbed by the negative pressure adsorption mechanism 4. Please continue to refer to Figure 2 In this embodiment of the utility model, the wire clamping mechanism 2 is disposed on the top of the wire take-up box 1, including a clamping assembly 21 that clamps the wire end and places it at the wire inlet 11, and a wire clamping drive 22 that drives the clamping assembly 21 to move; the clamping assembly 21 is used to clamp the head of the speaker wire, and the clamping drive 22 is the prior art, which can move in the XYZ directions to realize the clamping and wire pulling operation of the wire. After the wire is pulled out, the clamping drive 22 drives the clamping assembly 21 to move to the wire inlet 11; Figure 2 As shown in the embodiment of this utility model, the brushing mechanism 3 includes a brush 31 rotatably connected to the inlet 11 and a brushing drive 32 for driving the brush 31 to rotate. It should be noted that the brush 31 has bristles, which can be rotated by the drive of the brushing drive 32 to brush off the wire ends on the wire clamping assembly and prevent secondary pollution caused by adsorption on the wire clamping assembly.

[0024] In embodiments of this utility model, such as Figure 3 As shown, the negative pressure adsorption mechanism 4 is connected to the take-up box 1 and is used to apply negative pressure suction towards the inside of the take-up box 1. It should be noted that the function of the negative pressure adsorption mechanism 4 is to create negative pressure at the inlet 11 by connecting with the take-up box 1, thereby adsorbing the wire end that has fallen into the inlet 11 by the clamping assembly. In this embodiment of the present invention, when the clamping assembly 21 moves to the inlet 11 and opens, the brush 31 rotates and contacts the clamping assembly 21 to brush the wire end into the inlet 11.

[0025] In the embodiments of this utility model, the clamping and pulling operations of the lead wire are realized by the wire clamping assembly. After the wire end is pulled off, the wire clamping assembly moves into the wire inlet 11 and contacts the brush 31. After the clamping assembly 21 is opened, the excess wire end is cleaned by the rotation of the brush 31 and the negative pressure generated by the adsorption mechanism, thereby completing one operation.

[0026] In the above embodiment, the excess wire ends of the speaker are clamped and pulled out by the wire clamping mechanism 2. The excess wire ends are adsorbed by the brush 31 and the negative pressure mechanism connected to the wire take-up box 1, so that the clamped excess wire ends are adsorbed through the wire inlet 11. Compared with the prior art, no manual processing is required, which also improves the reliability of excess wire end removal. The negative pressure adsorption reduces secondary pollution.

[0027] Based on the above embodiments, the specific structure of the negative pressure adsorption mechanism 4 is as follows: Figure 3 As shown, the negative pressure adsorption mechanism 4 includes a duct 41 connected to the inner cavity of the cable take-up box 1, a dust collection filter 42 connected to the other end of the duct 41, and an air pump 43 connected to the dust collection filter 42. The function of the filter 42 is to collect and block the cable ends, preventing them from entering the air pump 43 due to adsorption force. In this embodiment of the invention, the filter 42 has a filter screen inside, which can collect and adsorb the pulled-out cable ends for centralized processing. The filter 42 is detachably connected to the air pump 43, which can clean up when too many cable ends accumulate. There are various specific detachable connection methods, such as using a gap fit to achieve a plug-in connection, or using other connection methods commonly used in the art. It should be noted that in this embodiment of the invention, the air pump 43 can be a turbine air pump, which uses high-speed rotating turbine blades to create a directional flow of air to form negative pressure.

[0028] In the embodiments of this utility model, the specific structure of the take-up box 1 is as follows: Figure 4 As shown, the cable inlet 11 is located at the front end of the top of the cable take-up box 1. A pipe connector 12 is also connected to the side wall of the cable take-up box 1 away from the cable inlet 11, and the pipe connector 12 is connected to the air duct 41. By positioning the pipe connector 12 on the side away from the cable inlet 11, an air duct can be formed between the cable inlet 11 and the pipe connector 12, which is beneficial for collecting the cable ends. Furthermore, in this embodiment of the invention, the cable take-up box 1 is also inclinedly provided with a toothed plate 13. The toothed end of the toothed plate 13 is tangent to the brush 31, and the end of the toothed plate 13 away from the brush 31 extends to the inside of the pipe connector 12. Figure 4 As shown, the toothed plate 13 can remove lint adhering to the brush 31, thereby improving the cleaning effect; in addition, for ease of maintenance, please refer to... Figure 4 The toothed plate 13 is detachably fixed inside the take-up box 1, and a cover plate 14 is also provided on the top of the take-up box 1. In actual use, if it is necessary to clean the cable ends, the cover plate 14 can be opened to clean the cable ends on the toothed plate 13. A more thorough cleaning can also be performed by disassembling the toothed plate 13. It should be noted that the cover plate 14 helps to better seal the air inside the take-up box, resulting in stronger suction and preventing the lead cable from falling outside the take-up box.

[0029] Please continue to refer to Figure 2In this embodiment of the invention, the brush drive 32 is a DC motor, and the brush drive 32 is connected to the brush 31 via a belt 33. The DC motor allows for speed regulation, thereby improving the cleaning effect by controlling the rotation speed of the brush 31; the belt 33 connects the DC motor and the brush 31, enabling the motor's power to be transmitted to the brush 31.

[0030] Specifically, such as Figure 5 As shown in the embodiment of this utility model, the clamping assembly 21 includes a clamping base 211 connected to the wire clamping drive 22 and at least one pair of clamping members 212 fixed on the clamping base 211. The clamping angle of the clamping members 212 is adapted to the direction of the wire end to be clamped. In this embodiment of the utility model, the wire clamping drive 22 can be a three-axis robot in a workshop, thereby realizing XYZ, i.e., up, down, left, right, forward, and backward movement; in addition, in this embodiment of the utility model, the clamping base 211 can be made of aluminum. When specifically fixing the clamping members 212, the direction of the lead wire is considered, such as... Figure 5 As shown, the clamping direction of the clamping member 212 is perpendicular to the direction of the lead wire.

[0031] In the embodiments of this utility model, please continue to refer to... Figure 5 The clamping component 212 is a finger cylinder, and a gripper 213 is fixed on the finger cylinder. It should be noted that, in embodiments of this invention, the finger cylinder uses air pressure to control the opening or closing of the gripper 213. The gripper 213 can be made of 304 stainless steel to improve wear resistance. The center distance of the gripper 213 can be designed according to the direction of the voice coil to facilitate synchronous clamping of the wire end. It should also be noted that, in some embodiments of this invention, features such as... Figure 5 The four finger cylinders shown are used to simultaneously clamp the voice coil leads at two workstations. During clamping, the clamping drive 22 is configured to move the jaws 213 to contact the brush 31 after clamping the wire end, and the clamping member 212 opens after being moved to contact the brush 31. This structural design automates the process. In practice, visual recognition or sensing methods can be used to ensure the lead tooling is in place, thereby improving the reliability of clamping.

[0032] Please refer to Figure 6 and Figure 7 In an embodiment of this utility model, to improve the reliability of the belt 33 driving the brush 31, the belt 33 is connected to the brush 31 at the middle of its axial direction. Please refer to... Figure 7The brush 31 is divided into two parts along its axial direction, and the middle part of the brush 31 is connected to the belt 33. This method allows the driving force from the belt 33 on the brush 31 to be more evenly distributed, resulting in smoother rotation of the brush 31. Furthermore, to prevent thread ends from falling onto the connection point between the belt 33 and the brush 31, such as... Figure 7 As shown in the embodiment of this utility model, an arc-shaped cover 15 covering the connection between the brush 31 and the belt 33 is also fixed on the take-up box 1. It should be noted that the arc of the arc-shaped cover 15 is adapted to the diameter of the brush 31. The arc-shaped cover 15 can be fixed on the take-up box 1 by screwing. With this structure, the number of wire ends falling to the connection between the belt 33 and the brush 31 is reduced, thereby reducing the damage of the wire ends to the connection between the brush 31 and the belt 33 and improving the service life of the equipment.

[0033] Furthermore, in embodiments of this utility model, the turbine air pump generates a significant amount of noise during operation, which can cause sound pollution to the workshop environment, such as... Figure 3 As shown, the exhaust end of the air pump 43 is also connected to a silencer 431. It should be noted that the silencer 431 includes a tubular outer shell connected to the end of the air pump, and a porous sound-absorbing material is provided inside the outer shell. This allows sound waves to enter the tiny pores of the porous material, causing air molecules to vibrate and rub against the pore walls, converting sound energy into heat energy and dissipating it. By setting up the silencer 431, the noise generated by the exhaust of the air pump 43 can be reduced, thereby reducing the noise in the production environment.

[0034] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
