Description

Technical Field

[0001] This utility model relates to the field of speaker voice coil winding technology, specifically a speaker voice coil winding machine with wire clamping and cutting. Background Technology

[0002] The voice coil winding process is the core manufacturing step in loudspeaker production, where enameled wire is wound in an orderly fashion onto a voice coil frame according to specific technological requirements, ultimately forming a toroidal voice coil winding. As the power source of the loudspeaker's vibration system, the quality of the voice coil winding directly determines whether the loudspeaker can stably convert electrical signals into mechanical vibrations, thereby producing clear sound quality.

[0003] Currently, in the speaker voice coil winding process, the wire cutting and clamping steps largely rely on manual operation. This process is not only inefficient but also suffers from inconsistent quality, ultimately affecting the overall production efficiency. Therefore, a speaker voice coil winding machine with wire clamping and cutting is needed. Utility Model Content

[0004] The purpose of this invention is to provide a wire-clamping and wire-cutting speaker voice coil winding machine. By setting up a clamping and cutting component, the machine can automatically execute the wire clamping and cutting actions during the voice coil winding process, thereby solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wire-clamping and cutting speaker voice coil winding machine includes a machine body, on the outside of which a pin is installed, and one end of the pin is provided with a wire-clamping and cutting component for clamping and cutting voice coil wires;

[0007] The clamping and cutting assembly includes a wire-hanging seat connected to one end of a pin. Blades are symmetrically mounted on both ends of the wire-hanging seat via a wire-cutting clamp sleeve. A blade core is installed inside the wire-cutting clamp sleeve on the side wall of each set of blades. A bearing is connected to one end of each set of blade cores via a top wheel seat. A spring is installed between the wire-cutting clamp sleeve and the top wheel seat. Each set of springs is sleeved on the outside of the corresponding blade core. Two sets of push plates are movably mounted on the side wall of the body. Each set of push plates can move to drive the corresponding bearing to move, thereby driving the blade core to clamp and release the voice coil wire.

[0008] Preferably, a motor is installed inside the machine body, and the output end of the motor extends through to the outside of the machine body.

[0009] Preferably, the pin is connected to the output end of the motor, and a fixing component is installed at the end of the pin away from the motor.

[0010] Preferably, the outer wall of the fastener is provided with an annular mounting groove, the middle of the hanging seat is provided with a mounting hole corresponding to the mounting groove, and a positioning pin is installed through the corresponding mounting hole inside each set of mounting grooves.

[0011] Preferably, four sets of fixed flanges are installed through the side wall of the machine body, and two sets of push rods are installed on the side wall of each set of push plates corresponding to the fixed flanges. One end of each set of push rods extends through the fixed flanges into the interior of the machine body.

[0012] Preferably, the machine body is equipped with two sets of cylinders, and each set of cylinders has a push rod fixing block installed at its output end, which is connected to the corresponding two sets of push rods.

[0013] Preferably, each set of push rod fixing blocks has a through hole in the middle, and each set of push rods is fixedly connected to the inside of the corresponding through hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides: a wire-clamping and wire-cutting speaker voice coil winding machine, such as... Figures 1-5 As shown, the device includes a body 1, with a pin 3 mounted on its exterior. One end of the pin 3 is equipped with a wire clamping and cutting assembly 5. The body 1 provides the mounting base and working support space for all components. The pin 3, mounted on the exterior of the body 1, connects to the wire clamping and cutting assembly 5 at one end and transmits power at the other, serving as a key connector between the body 1 and the wire clamping and cutting assembly 5. The wire clamping and cutting assembly 5 can perform wire clamping and cutting actions through the coordinated operation of all components.

[0024] The clamping and cutting assembly 5 includes a wire-hanging base 51 connected to one end of the pin 3. Blades 52 are symmetrically mounted on both ends of the wire-hanging base 51 via wire-cutting clamp sleeves 53. A blade core 54 is mounted inside the wire-cutting clamp sleeve 53 on the sidewall of each set of blades 52. A bearing 56 is connected to one end of each set of blade cores 54 via a top wheel seat 55. A spring 57 is installed between each set of wire-cutting clamp sleeves 53 and the top wheel seat 55, and each spring 57 is sleeved on the outside of its corresponding blade core 54. Two sets of push plates 58 are movably mounted on the sidewall of the body 1. Each set of push plates 58 can move to move its corresponding bearing 56, thereby causing the blade core 54 to clamp and release the voice coil wire. The wire-hanging base 51, connected to one end of the pin 3, serves as the mounting base for the clamping and cutting assembly 5, providing fixed support for components such as the blades 52 and wire-cutting clamp sleeves 53. The blades 52 are symmetrically mounted on both ends of the wire-hanging base 51 via the wire-cutting clamp sleeves 53. The blade core 54 is mounted on the side wall of the blade 52 and located inside the wire clip outer sleeve 53. It can slide along the inside of the wire clip outer sleeve 53 and clamps and cuts the voice coil wire through its cooperation with the blade 52. The top wheel seat 55 is connected to one end of the blade core 54, serving as a transition connection and transmitting the force of the bearing 56 to the blade core 54. The bearing 56 is mounted on the top wheel seat 55, which reduces the frictional resistance when the push plate 58 pushes, making the sliding of the blade core 54 smoother. The spring 57 is sleeved on the outside of the blade core 54, with its two ends connected to the wire clip outer sleeve 53 and the top wheel seat 55 respectively. It provides power for the sliding of the blade core 54 through its own compression and rebound. The push plate 58 is movably mounted on the side wall of the body 1. It pushes the bearing 56 by its own movement, thereby driving the blade core 54 to slide. During winding, the push plate 58 moves outward, pushing the bearing 56 and the top wheel seat 55 to move outward synchronously. The top wheel seat 55 drives the blade core 54 to slide outward along the wire-cutting clamp outer sleeve 53. At this time, the spring 57 is compressed, and a wire-passing gap is formed between the blade core 54 and the blade 52, allowing the voice coil wire to pass through for winding. After winding is completed, the push plate 58 retracts backward, and the spring 57 releases its elastic potential energy and rebounds, pushing the blade core 54 to return to its original position. The blade core 54 and the blade 52 cooperate to first clamp the voice coil wire, and then the continuous pressure of the blade core 54 causes the voice coil wire to contact the cutting edge of the blade 52 and be cut. Finally, the clamping and cutting actions are completed synchronously.

[0025] Preferably, a motor 2 is installed inside the machine body 1, with the output end of the motor 2 extending through to the outside of the machine body 1. The motor 2, installed inside the machine body 1, is the power source for the entire winding machine. After being connected to the power supply, it converts electrical energy into mechanical energy, outputting rotational power. The output end of the motor 2 extends through to the outside of the machine body 1, connecting with the pin 3 to provide power support for the rotation of the pin 3.

[0026] Motor 2 can be a small three-phase asynchronous motor with a power of 0.37kW-0.75kW and a rated speed of 1400r / min-2800r / min. The power of 0.37kW-0.75kW can stably drive the pin 3 and the clamping and shearing assembly 5 to rotate, and the speed of 1400r / min-2800r / min covers the wire diameter and number of turns requirements of conventional speaker voice coil winding, which can ensure winding efficiency and avoid voice coil wire breakage due to excessive speed and disruption of production rhythm due to excessive speed.

[0027] Furthermore, the pin 3 is keyed to the output end of the motor 2, and a fixing component 4 is inserted and installed at the end of the pin 3 furthest from the motor 2. The keyed connection between the pin 3 and the output end of the motor 2 ensures that the rotational power of the motor 2 is stably transmitted to the pin 3, preventing slippage during power transmission. The fixing component 4, in cooperation with the pin 3, is used to support and position the voice coil frame, and assists in fixing the axial position of the clamping and shearing assembly 5.

[0028] Furthermore, the outer wall of the fixing component 4 is provided with an annular mounting groove 6, and the middle of the hanging seat 51 is provided with a mounting hole 7 corresponding to the mounting groove 6. A positioning pin 8 is installed inside each set of mounting grooves 6, passing through the corresponding mounting hole 7. The annular mounting groove 6 on the outer wall of the fixing component 4 corresponds to the mounting hole 7 in the middle of the hanging seat 51, providing a positional reference for the installation of the positioning pin 8. The positioning pin 8 passes through the mounting groove 6 and the mounting hole 7, firmly fixing the fixing component 4 and the hanging seat 51 together. The rigid connection of the positioning pin 8 ensures no relative displacement between the hanging seat 51 and the fixing component 4, thereby ensuring the synchronous rotation of the clamping and shearing assembly 5 and the pin 3. Simultaneously, the annularly distributed mounting grooves 6 and positioning pins 8 ensure even force distribution on the hanging seat 51, preventing the clamping and shearing assembly 5 from shifting due to centrifugal force during winding, thus ensuring the accuracy of the voice coil winding and the precision of the clamping and shearing action.

[0029] It is worth noting that four sets of fixed flanges 9 are installed through the side wall of the body 1. Two sets of push rods 10 are installed on the side wall of each push plate 58 corresponding to the fixed flange 9. One end of each push rod 10 extends through the fixed flange 9 into the interior of the body 1. The fixed flanges 9, installed through the side wall of the body 1, serve to fix and guide, providing a stable channel for the sliding of the push rods 10 and preventing them from shifting during movement. The push rods 10, installed on the side wall of the push plate 58, with one end extending through the fixed flange 9 into the interior of the body 1, are transmission components connecting the push plate 58 and the push rod fixing block 12, transmitting power from the push rod fixing block 12 to the push plate 58.

[0030] Specifically, two sets of cylinders 11 are installed inside the machine body 1. Each set of cylinders 11 has a push rod fixing block 12 installed at its output end, which is connected to the corresponding two sets of push rods 10. The cylinders 11 are installed inside the machine body 1 and are the power source for driving the push plate 58 to move. The extension and retraction of their own piston rods drives the push rod fixing blocks 12 to move. The push rod fixing blocks 12 are used to connect the cylinders 11 and the push rods 10, so that the cylinders 11 can drive the push rods 10 to move.

[0031] Cylinder 11 can be a small standard cylinder with a diameter of 16mm-25mm, a stroke of 20mm-30mm, and a working pressure of 0.4MPa-0.6MPa. The combination of cylinder diameter and working pressure can output a thrust of 50N-245N, which can easily push the push plate to move the bearing and the cutter core, meeting the force requirements for the cutter core to clamp the voice coil wire; the 20mm-30mm stroke is precisely matched with the distance the push plate drives the cutter core to slide, ensuring that the cutter core completely retracts to form a wire-threading gap during winding, and can return to its original position after winding to complete the clamping and shearing action; the small cylinder is compact in size and can be flexibly installed inside the machine body without taking up too much space, and the working pressure of 0.4MPa-0.6MPa is within the pressure range of conventional pneumatic systems, eliminating the need for additional pressurization or depressurization equipment, ensuring continuous and efficient production of the winding machine.

[0032] More specifically, each set of push rod fixing blocks 12 has a through hole 13 in the middle, and each set of push rods 10 is fixedly connected to the corresponding through hole 13. The push rod fixing block 12 is installed at the output end of the cylinder 11, and the through hole 13 in the middle is used to fix the push rod 10, so that the two sets of push rods 10 are subjected to force synchronously, ensuring that the push plate 58 moves smoothly. When it is necessary to control the movement of the push plate 58, the piston rod of the cylinder 11 extends or retracts, driving the push rod fixing block 12 to move synchronously. The push rod fixing block 12 drives the push rod 10 to slide along the inside of the fixed flange 9 through the through hole 13, and the push rod 10 then pushes or pulls the push plate 58 to move on the side wall of the machine body 1, ultimately realizing the push or release of the bearing 56 by the push plate 58, providing power drive for the clamping and shearing action of the clamping and shearing assembly 5.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
