Description

Technical Field

[0001] The utility model relates to the field of loudspeaker production equipment, in particular to a loudspeaker voice coil residual wire cutting device. Background Art

[0002] The voice coil is a crucial component in audio equipment, serving multiple functions and benefits. As one of the most crucial components in audio equipment, it is widely used in devices such as speakers and microphones. It generates mechanical vibrations in a magnetic field through electric current, thereby driving the diaphragm to produce sound. The performance of the voice coil affects the speaker's sound pressure frequency characteristics, sound pressure level, impedance curve, distortion, transient characteristics, speaker parameters, sound quality, and more, particularly its power handling capacity and lifespan. After the voice coil is produced, the remaining wire is traditionally cut manually, and then welded to the wiring lugs. However, this traditional method of wire cutting is inefficient and prone to cutting too short or too long during the cutting process. This can lead to deviations when the voice coil is connected to the speaker, resulting in low production efficiency. Utility Model Content

[0003] The purpose of the utility model is to improve the efficiency of cutting the voice coil excess wire. Before the cutting process, the speaker is placed in the placement hole, and the two excess wires are placed in the slots respectively. When they are transported to the bottom of the cutting mechanism, they are quickly cut off, thereby improving production efficiency.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A device for cutting off the residual wire of a loudspeaker voice coil comprises a cutting mechanism, a conveying plate, a positioning plate and a cover plate. The cutting mechanism is symmetrically arranged on the left and right, and a connecting plate is arranged at the bottom of each cutting mechanism. The connecting plate is fixed to one side of the voice coil conveying line by a positioning screw. The conveying plate is movably installed on the voice coil conveying line. Positioning plates are fixedly arranged on the conveying plate symmetrically on the left and right. A cover plate is also arranged on the positioning plate. A placement hole is provided between the cover plate and the positioning plate. The placement hole is used to place the voice coil. The cutting mechanism comprises a support frame, an air pressure control plate, a step plate and a cutting assembly. The bottom of the support frame is fixedly connected to the connecting plate. An air pressure control plate is also arranged on the support frame. The front end of the air pressure control plate is fixedly connected to the step plate. A cutting assembly is arranged on the step plate.

[0006] Preferably, an air inlet pipe and a pressure relief pipe are further provided on one side of the air pressure control panel, and the air pressure control panel is also coordinated with a cut-off assembly.

[0007] Preferably, a transverse plate and a slide rail are provided on the step plate, the transverse plate is located on the upper part of the slide rail, and the transverse plate and the slide rail are arranged perpendicularly, the cutting assembly is respectively installed in cooperation with the transverse plate and the slide rail, and the number of the slide rails is not less than two.

[0008] Preferably, the cutting assembly includes a cylinder, a slider, a moving block, a cutting plate, a positioning rod, a cutting rod, a slice, a return spring, a lifting rod and a limit block. The cylinder is fixed symmetrically on the step plate, the slider is movably installed on the slide rail, the telescopic end of the cylinder is fixedly connected to the slider, a moving block is provided at the front end of the slider, a cutting plate is provided at the bottom of the moving block, a positioning rod and a cutting rod are respectively provided at the bottom of the cutting plate, a slice is provided at the bottom of the cutting rod, the upper part of the moving block is fixedly connected to the bottom of the lifting rod, the limit block is installed on the horizontal plate, and the upper part of the lifting rod passes through the limit block.

[0009] Preferably, an induction probe is fixedly provided on the bottom of the transverse plate, and the induction probe is located in the middle of the two cylinders.

[0010] Preferably, notches are provided on both sides of the cover plate, and positioning holes are also provided on both sides of the positioning plate, and the positioning holes are located on both sides of the cover plate.

[0011] Principle of this utility model:

[0012] Before cutting the residual wire, it is necessary to place the voice coil in the placement hole on the positioning plate, then stretch the residual wire to be cut, and then fix the cover plate on the positioning plate. In this process, the residual wire is pressed between the positioning plate and the cover plate, and the residual wire can be seen through the notch on the cover plate. The voice coils are placed symmetrically on the left and right sides of the conveyor plate, and then the conveyor plate is transferred to the bottom of the cutting mechanism. When the induction probe detects the signal, the two cylinders work separately, so that the moving block drives the positioning rod and the cutting rod to move downward. When cutting, the positioning rod is partially located in the positioning hole, and the cutter is located in the notch, and the residual wire is cut by stamping. After the cutting is completed, under the simultaneous action of the return spring and the cylinder, the moving block drives the cutter and the positioning rod away to complete the cutting. During the cutting process, the residual wires of the two voice coils can be cut at the same time, which not only has high cutting efficiency, but also consistent length of the residual wires.

[0013] The beneficial effects of the present invention are:

[0014] 1. Through the positioning plate and the cover plate, before the cutting process, the voice coil is placed in the placement hole on the positioning plate, and then the excess wire to be cut is stretched, and then the cover plate is fixed on the positioning plate. In this process, the excess wire is pressed between the positioning plate and the cover plate, and the excess wire can be seen through the notch on the cover plate. This step is equivalent to the preparation work before cutting, which facilitates subsequent cutting.

[0015] 2. Through two symmetrically arranged cutting mechanisms, the remaining wires of the two voice coils are cut simultaneously. During the cutting process, the positioning rod can prevent the slices from being damaged. When the slices contact the upper surface of the positioning plate, the positioning rod just contacts the upper surface of the conveying plate, so that the remaining wires can be cut off without becoming blunt.

The air pressure control panel 12 mainly transmits air pressure to the cut-off assembly 14, so that the cylinder 140 on the cut-off assembly 14 works.

[0027] A transverse plate 9 and a slide rail 10 are provided on the step plate 13. The transverse plate 9 is located on the upper part of the slide rail 10, and the transverse plate 9 and the slide rail 10 are vertically arranged. The cutting assembly 14 is respectively installed in conjunction with the transverse plate 9 and the slide rail 10, and the number of the slide rails 10 is not less than two. The slide rail 10 is mainly equipped with a slider 141, and the slider 141 moves up and down with the telescopic end of the cylinder 140.

[0028] The cutting assembly 14 includes a cylinder 140, a slider 141, a moving block 142, a cutting plate 143, a positioning rod 144, a cutting rod 145, a slice 146, a return spring 147, a lifting rod 148 and a limit block 149.

[0029] Cutting principle:

[0030] Before the cutting process, the voice coil needs to be positioned and installed first. Specifically, the voice coil is placed in the placement hole 6 on the positioning plate 3, and then the remaining wire to be cut is stretched, and then the cover plate 4 is fixed on the positioning plate 3. In this process, the remaining wire is pressed between the positioning plate 3 and the cover plate 4, and the remaining wire can be seen through the notch 21 on the cover plate 4. The voice coils are placed symmetrically on the left and right sides of the conveying plate 2, and then transferred to the bottom of the cutting mechanism 1 with the conveying plate 2. When the sensing probe 20 detects the signal, the two cylinders 140 work separately, so that the moving block 142 drives the positioning rod 144 and the cutting rod 145 to move downward. When cutting, the positioning rod 144 is partially located in the positioning hole 22, and the cutter 146 is located in the notch 21, and the remaining wire is cut by stamping. After the cutting is completed, under the simultaneous action of the return spring 147 and the cylinder 140, the moving block 142 drives the cutter 146 and the positioning rod 144 away to complete the cutting. During the cutting process, the remaining wires of the two voice coils can be cut at the same time, which not only has high cutting efficiency but also makes the remaining wires consistent in length.

[0031] The bottom of the transverse plate 9 is also fixed with a sensing probe 20, and the sensing probe 20 is located in the middle of the two cylinders 140. The sensing probe 20 mainly senses the conveying plate 2, and the purpose is to make the notch 21 and the slice 146 relative to each other so that there is no misalignment.

[0032] The cover plate 4 is provided with notches 21 on both sides, and the positioning plate 3 is provided with positioning holes 22 on both sides, and the positioning holes 22 are located on both sides of the cover plate 4. The remaining thread of the tape can be observed through the notches 21 before cutting.

[0033] The positioning rod 144 is aligned with the positioning hole 22, and the slice 146 is aligned with the notch 21 on the cover plate 4. The positioning rod 144 can prevent the slice 146 from being damaged. When the slice 146 contacts the upper surface of the positioning plate 3, the positioning rod 144 just contacts the upper surface of the conveying plate 2, so that the remaining line can be cut off without becoming blunt.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
