Description

Technical Field

[0001] This utility model relates to the field of voice coil technology, specifically to a voice coil soldering device for easy positioning. Background Technology

[0002] The voice coil is an important component of a loudspeaker. It moves in a magnetic field through the movement of an electric current, which in turn causes the diaphragm to vibrate and produce sound. During the voice coil manufacturing process, after the voice coil frame is wound with enameled wire, two leads are formed. These two leads need to be soldered together with nylon wire.

[0003] Currently, during the voice coil soldering process, the lead wires and cotton wires are both quite thin, making it difficult to position and align the lead wire ends with the cotton wire ends, which reduces soldering efficiency and quality. To address this, we propose a voice coil soldering device that facilitates positioning. Utility Model Content

[0004] The purpose of this invention is to provide a convenient voice coil soldering device that facilitates the positioning and docking of lead wire ends and cotton thread ends during the voice coil soldering process, thereby improving soldering efficiency and quality. It is also applicable to soldering lead wires and cotton thread ends of varying thicknesses, thus enhancing its versatility. This invention solves the problem that in current voice coil soldering processes, due to the thinness of both the lead wires and cotton thread ends, it is difficult to position and dock the lead wire ends with the cotton thread ends, resulting in reduced soldering efficiency and quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a voice coil soldering device for convenient positioning, comprising a base, a groove provided on the upper surface of the base, a bidirectional lead screw installed inside the groove, a first threaded slider and a second threaded slider respectively installed on both sides inside the groove, a positioning seat installed on the upper surface of the first threaded slider and the second threaded slider, a V-shaped groove provided on the upper surface of each positioning seat, a fixed electric cylinder installed on the upper surface of the first threaded slider and the second threaded slider via a fixing frame, a pressure plate connected to the output end of each fixed electric cylinder, a welding frame installed at the middle position of the upper surface of the base, a lifting electric cylinder installed at the bottom of the inner wall of the welding frame, a welding seat connected to the output end of the lifting electric cylinder, a welding electric cylinder installed on the upper surface of the welding frame, and a welding head connected to the output end of the welding electric cylinder.

[0006] Preferably, a post is installed on the upper surface of the first threaded slider near the outer side.

[0007] Preferably, the bidirectional lead screw passes through the first threaded slider and the second threaded slider, and the threads on the inner walls of the first threaded slider and the second threaded slider mesh with the threads on the outer surface of the bidirectional lead screw.

[0008] Preferably, a rotary motor is installed on one side of the outer surface of the base, and the end of the output shaft of the rotary motor is connected to the end of the bidirectional lead screw.

[0009] Preferably, a limit frame is installed on the upper surface of the base near the inner side of the first and second threaded sliders, and a movable electric cylinder is installed on the rear surface of each limit frame, with a limit stop connected to the output end of each movable electric cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting up a base, sliding groove, bidirectional lead screw, first threaded slider, second threaded slider, fixed frame, fixed electric cylinder, pressure plate, positioning seat, V-shaped groove, welding frame, welding electric cylinder, welding seat, and lifting electric cylinder, achieves the effect of facilitating the positioning and docking of lead wire ends and cotton thread ends during voice coil soldering, improving welding efficiency and quality, and is applicable to welding lead wires and cotton thread of different thicknesses, thus improving applicability. The lead wires and cotton thread on the voice coil are placed inside the V-shaped groove, with the lead wire ends and cotton thread ends extending to the outside of the V-shaped groove. The output end of the fixed electric cylinder drives the pressure plate to descend, fixing the lead wires and cotton thread inside the V-shaped groove. The bidirectional lead screw rotates, causing the first threaded slider and second threaded slider to move in opposite directions. The output end of the lifting electric cylinder drives the welding seat to rise and fall to adjust its height, so that the lead wire ends and cotton thread ends are docked precisely on the welding seat. The operation of the welding electric cylinder causes the welding head to descend, and works with the solder wire to complete the welding of the lead wire ends and cotton thread ends.

[0012] 2. This utility model achieves the effect of controlling the length of the lead wire and cotton thread leading out of the V-shaped groove by setting a limiting frame, a moving electric cylinder, and a limiting stop bar. The output ends of the two moving electric cylinders drive the two limiting stops to move to positions close to the inner side of the two positioning seats. When the lead wire and cotton thread are led out of the V-shaped groove, they are restricted by the limiting stops to control the length of the lead wire and cotton thread leading out of the V-shaped groove, so that the lead wire and cotton thread leading out of the V-shaped groove are just connected at the welding seat position.

A rotary motor 1 is installed on one side of the outer surface of the base 2. The end of the output shaft of the rotary motor 1 is connected to the end of the bidirectional lead screw 4. The rotary motor 1 drives the bidirectional lead screw 4 to rotate. A first threaded slider 5 and a second threaded slider 8 are respectively installed on both sides inside the groove 3. The bidirectional lead screw 4 passes through the first threaded slider 5 and the second threaded slider 8. The threads on the inner walls of the first threaded slider 5 and the second threaded slider 8 mesh with the threads on the outer surface of the bidirectional lead screw 4. When the bidirectional lead screw 4 rotates, it can drive the first threaded slider 5 and the second threaded slider 8 to move in opposite directions or in reverse. A post 9 is installed on the upper surface of the first threaded slider 5 near the outer side. When the voice coil is placed on the upper surface of the first threaded slider 5, the post 9 is inserted into the voice coil to fix it.

[0021] Positioning seats 13 are installed on the upper surfaces of the first threaded slider 5 and the second threaded slider 8. Each positioning seat 13 has a V-shaped groove 14 on its upper surface. Fixed electric cylinders 11 are installed on the upper surfaces of the first threaded slider 5 and the second threaded slider 8 through a fixing frame 10. Each fixed electric cylinder 11 has a pressure plate 12 connected to its output end. A welding frame 6 is installed at the middle position on the upper surface of the base 2. A lifting electric cylinder 15 is installed at the bottom of the inner wall of the welding frame 6. A welding seat 16 is connected to the output end of the lifting electric cylinder 15.

[0022] In use, the lead wire and cotton thread on the voice coil are placed inside the V-shaped groove 14, with the lead wire end and cotton thread end extending to the outside of the V-shaped groove 14. The output end of the fixed electric cylinder 11 drives the pressure plate 12 to descend, fixing the lead wire and cotton thread inside the V-shaped groove 14. The bidirectional lead screw 4 rotates, causing the first threaded slider 5 and the second threaded slider 8 to move in opposite directions. The output end of the lifting electric cylinder 15 drives the welding seat 16 to rise and fall to adjust its height, so that the lead wire end and cotton thread end are aligned on the welding seat 16. The welding electric cylinder 17 operates, causing the welding head 18 to descend and, together with the solder wire, complete the welding of the lead wire end and cotton thread end.

[0023] Example 2
