Description

Technical Field

[0001] This utility model relates to the field of production mold technology, and in particular to a voice coil stretching forming machine. Background Technology

[0002] As the moving part of a miniature sound-generating device, the voice coil generates a magnetic field that changes with the audio current when an alternating audio current passes through it. This changing magnetic field attracts or repels the magnetic field of the magnetic circuit system of the miniature electroacoustic device, causing the voice coil to vibrate mechanically, which in turn drives the diaphragm of the miniature electroacoustic device to vibrate. The diaphragm vibrates repeatedly, pushing the air to produce sound. It is evident that the voice coil affects the performance of the entire miniature electroacoustic device.

[0003] Chinese Patent CN218191967U discloses a voice coil stretching and forming device. Addressing the problem that many stretching devices used in voice coil production easily damage the voice coil during stretching, causing property loss and affecting production efficiency, the following solution is proposed: The device includes a housing with a cylinder mechanism on its side and a winding rotation mechanism on its inner side. Two second fixed rods are located on the other side of the housing's interior. A second rotating rod is rotatably connected to the outer front end of each of the second fixed rods. This device uses a motor to drive a rotating plate, which in turn drives a winding rod to rotate around the two second rotating rods. A cylinder pulls the second rotating rods along the second fixed rods, distributing the winding coil across the second rotating rods to prevent coil accumulation. The two second rotating rods are used to stretch the voice coil, preventing breakage during stretching and thus product damage.

[0004] The existing voice coil stretching and forming structure is located inside the enclosure. After the voice coil stretching and forming is completed, it is inconvenient to operate and remove it from the enclosure, which greatly reduces the ease of use. At the same time, it is difficult to adjust the distance between the two fixed rods in the structure, and the position of the rotating rod cannot be flexibly adjusted, which limits the applicability of voice coil stretching and forming and reduces the overall practicality of the forming machine.

[0038] Example 2

[0039] like Figure 4 As shown, the present invention proposes a voice coil stretching forming machine. Based on the above embodiments, this embodiment also details the specific components of the stretching assembly and their mating methods.

[0042] The working principle of this utility model is as follows: During use, the driving components of the voice coil stretching forming machine are connected to the control system and power supply via wires. The driving components include a hydraulic telescopic column 202, a rotary motor 301, an electric telescopic rod 305, two cylinders, and a servo motor 408. Starting the rotary motor 301 causes the turntable 302 to rotate. The rotation of the turntable 302, through components such as the base 303, mounting frame 304, and fixing plate 307, causes the wire rod 308 to rotate for winding the wire. When the position of the wire rod 308 needs to be adjusted, the electric telescopic rod 305 is activated. The electric telescopic rod 305 moves the connecting block 306, which in turn moves the fixing plate 307, thereby causing the fixing plate 307 to move the wire rod 308, achieving position adjustment. When the distance between the two fixing rods 403 needs to be adjusted, the servo motor is activated. 408, the servo motor 408 rotates the threaded rod 407, the threaded rod 407 is threadedly engaged with the moving block 406, the two sides of the moving block 406 are connected to the guide rod 410 through sliding, thereby realizing the linear movement of the moving block 406. The movement of the moving block 406 drives the moving seat 405, which is connected to the stretching part b404, so that the stretching part b404 can be adjusted in position, realizing the adjustment of the distance between the stretching part a and the stretching part b404, which facilitates the use of the voice coil stretching forming machine. After the voice coil stretching is completed, the hydraulic telescopic column 202 is activated. The driving end of the hydraulic telescopic column 202 causes the moving plate 201 to move. The moving plate 201 drives the moving base plate 2. The rotating component 3 and the stretching component connected to the moving base plate 2 move out of the housing 1, which makes it easy for the staff to take it out, thus improving the practicality of the voice coil stretching forming machine.

[0043] 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.
