Description

Technical Field

[0001] This utility model relates to the field of voice coil manufacturing technology, and in particular to an automatic voice coil winding machine. Background Technology

[0002] The voice coil is a crucial component of the vibration system of an electrodynamic loudspeaker, often referred to as the heart of the loudspeaker. The performance of the voice coil affects various parameters of the loudspeaker, including its sound pressure frequency response, sound pressure level, impedance curve, distortion, transient response, loudspeaker parameters, and sound quality. In particular, it relates to the loudspeaker's power handling capacity and lifespan.

[0003] Chinese Patent No. CN220776072U discloses a voice coil winding device, including a housing, a fixed plate, and a movable plate. A mounting base is fixedly connected to the top of the housing, and a motor is fixedly mounted on the top of the mounting base. A welding device is mounted on one side of the fixed plate. By setting up the movable plate and the workpiece shaft, the voice coil workpiece is fixed to one end of the workpiece shaft. The motor is started, and the movable plate is conveyed to the fixed plate via a conveying mechanism. The copper wire on the coil drum is then placed on the outside of the voice coil workpiece and bonded using the welding device. The rotation of the motor drives the workpiece shaft and the voice coil workpiece to rotate, thereby achieving voice coil winding. This device offers good convenience and practicality, saves labor costs, and improves processing quality.

[0004] However, the above technical solution has the following shortcomings: after the copper wire is placed on the voice coil workpiece, the copper wire needs to be evenly wound on the voice coil workpiece. However, the above device does not guide the copper wire, and the copper wire is easy to pile up, which affects the quality of the voice coil. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic voice coil winding machine that uses a motor c to drive a mounting plate to rotate, the mounting plate to pull a slider to reciprocate, and a motor d to drive a guide block to abut against both sides of the copper wire. The guide block then drives the copper wire to move according to the winding requirements.

[0006] The technical solution of this utility model is an automatic voice coil winding machine, comprising: a base frame on which an input / output mechanism, a welding assembly, and a traction assembly are mounted; a clamping mechanism mounted on the base frame, with the welding assembly distributed below the clamping mechanism; and a wire assembly comprising a motor c mounted on the base frame, a mounting plate mounted on the output end of motor c, a connecting rod rotatably mounted on the mounting plate, a slider slidably mounted on the base frame, a motor d mounted on the slider, a bidirectional lead screw mounted on the output end of motor d, and two wire blocks threadedly connected to each other on the bidirectional lead screw; the connecting rod is rotatably connected to the slider.

[0007] Preferably, the clamping mechanism includes a rotating frame mounted on a base frame, and multiple sets of clamping components evenly arranged in a ring on the rotating frame.

[0008] Preferably, the clamping assembly includes a motor a mounted on a rotating frame, an elliptical block mounted on the output end of motor a, two clamping plates rotatably mounted on the rotating frame, a spring mounted between each of the two clamping plates and the rotating frame, and an abutment assembly rotatably mounted on each of the two clamping plates.

[0009] Preferably, the abutment assembly includes a rotating cylinder rotatably mounted on the clamping plate, a bearing mounted on the rotating cylinder, an abutment rod mounted on the bearing, and a driving member mounted on the rotating cylinder.

[0010] Preferably, the abutment rod has a tapered block portion.

[0011] Preferably, the input / output mechanism includes a conveyor belt, the outer circumferential surface of which has a plurality of evenly distributed arc-shaped grooves.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] In use, the voice coil workpiece is placed on a conveyor belt and moved to the clamping mechanism. The clamping assembly holds the voice coil workpiece, the traction assembly pulls the copper wire to the voice coil workpiece, and the welding assembly welds the copper wire to the voice coil workpiece. Then, the clamping mechanism drives the voice coil workpiece to rotate, thereby moving the copper wire. At the same time, the motor C drives the mounting plate to rotate. During the rotation of the mounting plate, the mounting plate pulls the slider to move. The slider completes one reciprocating motion when the mounting plate rotates one revolution. When the copper wire is wound around the voice coil workpiece once, the user manually cuts the copper wire and welds the end, thereby improving the winding quality of the voice coil.

[0019] Example 1

[0020] like Figures 1-4 As shown, this embodiment proposes an automatic voice coil winding machine, including a base frame 1, a clamping mechanism 3, and a wire assembly. The base frame 1 is equipped with an input / output mechanism, a welding assembly 4, and a traction assembly 5. The welding assembly 4 consists of a hydraulic cylinder, a welding gun, and an air tank. The hydraulic cylinder drives the welding gun to rise and fall. The traction assembly 5 consists of a motor b, a mounting rod rotatably mounted on the base frame 1, and a mechanical claw mounted on the mounting rod. The mechanical claw has the same structural type as the PGN-plus-P universal robotic arm. The mechanical claw pulls the copper wire to the clamping mechanism 3, and the hydraulic cylinder drives the welding gun to move to the copper wire for welding. The invisible structures such as the air tank and lamp on the winding machine are all distributed on the base frame 1.

[0021] The clamping mechanism 3 is mounted on the base frame 1, and the welding assembly 4 is distributed below the clamping mechanism 3. The wire assembly 7 includes a motor c71 mounted on the base frame 1, a mounting plate 72 mounted on the output end of the motor c71, a connecting rod 73 rotatably mounted on the mounting plate 72, a slider 74 slidably mounted on the base frame 1, a motor d76 mounted on the slider 74, a bidirectional lead screw 77 mounted on the output end of the motor d76, and two wire blocks 75 threadedly connected to the bidirectional lead screw 77. The connecting rod 73 is rotatably connected to the slider 74. The input / output mechanism includes a conveyor belt with multiple evenly distributed arc-shaped grooves on its outer circumference. The input / output mechanism includes an input assembly 2 and an output assembly mounted on the base frame 1. The input assembly 2 and the output assembly have the same structure. One of each is distributed on the input assembly 2 and the output assembly. After the voice coil workpiece is placed on the conveyor belt, multiple voice coil workpieces will be placed one by one in the multiple arc-shaped grooves.

[0022] In this embodiment, the voice coil workpiece is placed on the conveyor belt and moved to the clamping mechanism 3. The clamping component clamps the voice coil workpiece, the traction component pulls the copper wire to the voice coil workpiece, and the welding component welds the copper wire to the voice coil workpiece. Then, the clamping mechanism drives the voice coil workpiece to rotate, thereby driving the copper wire to move. At the same time, the motor C71 drives the mounting plate 72 to rotate. During the rotation of the mounting plate 72, the sliding block 74 is moved. The sliding block 74 achieves one reciprocating motion when the mounting plate 72 rotates one revolution. When the copper wire is wound around the voice coil workpiece once, the user manually cuts the copper wire and welds the end, thereby improving the winding quality of the voice coil.

[0023] Example 2

[0024] like Figure 1 and Figure 2 As shown, this embodiment proposes an automatic voice coil winding machine. Compared with the first embodiment, in this embodiment, the clamping mechanism 3 includes a rotating frame 31 mounted on the base frame 1, and multiple sets of clamping components evenly arranged in a ring on the rotating frame 31. The base frame 1 is equipped with a driving component, which can be a common driving component such as a motor. The driving component drives the rotating frame 31 to rotate, and the multiple clamping components clamp multiple voice coil workpieces sequentially to the voice coil winding point, thereby reducing the labor intensity of the workers. The rotating frame 31 and the base frame 1 are equipped with carbon brushes and slip ring structures, so that the base frame 1 can supply power to the multiple motors a32 and driving components on the rotating frame 31 through the carbon brushes and slip ring structures.

[0025] The clamping assembly includes a motor a32 mounted on a rotating frame 31, an elliptical block 33 mounted on the output end of the motor a32, two clamping plates 34 mounted rotatably on the rotating frame 31, a spring 35 mounted between each of the two clamping plates 34 and the rotating frame 31, and an abutment assembly 36 mounted rotatably on each of the two clamping plates 34.

[0026] In this embodiment, motor a32 drives elliptical block 33 to rotate. As elliptical block 33 rotates, it pushes two clamping plates 34 to rotate. The two clamping plates 34 move toward the voice coil workpiece until the two abutting components 36 abut against both ends of the voice coil workpiece. After the winding is completed, elliptical block 33 rotates, and spring 35 pulls abutting components 36 to move in the opposite direction to the voice coil workpiece, thereby realizing automatic loading and unloading of the voice coil workpiece.

[0027] Example 3

[0028] like Figure 1 , Figure 2 and Figure 4As shown, this embodiment of the automatic voice coil winding machine, compared to Embodiment 1, includes a contact assembly 36 comprising a rotating cylinder 361 rotatably mounted on a clamping plate 34, a bearing 362 mounted on the rotating cylinder 361, a contact rod 363 mounted on the bearing 362, and a driving component mounted on the rotating cylinder 361. The driving component can be a common small motor. The contact rod 363 has a tapered block portion.

[0029] In this embodiment, the driving component drives the abutment rod 363 to rotate, and the bearing 362 reduces the friction during the rotation of the abutment rod 363. The conical block on the abutment rod 363 can clamp voice coil workpieces of different volumes by abutting against the voice coil workpiece. Clamping voice coil workpieces of different volumes requires the user to manually pull and weld copper wire, thereby improving the versatility of the winding machine.

[0030] 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.
