Description

Technical Field

[0001] The utility model relates to the technical field of voice coil production jigs, in particular to a wire-flipping prevention jig for winding a square wire voice coil. Background Art

[0002] The voice coil is a crucial component of a loudspeaker. It consists primarily of a bobbin and coil, formed by diffracting copper wire around the bobbin. Due to design requirements, some voice coils require the use of square copper wire. Due to the structure of the square wire, wire twisting often occurs during winding, leading to poor winding. Normally, the four flat surfaces of adjacent loops are stacked, but during winding, the four corners of adjacent loops are stacked. This results in an uneven winding surface, affecting the maximum outer diameter of the voice coil and the conductor footprint, failing to meet production requirements. Summary of the Invention

[0003] The problem to be solved by the utility model is to provide a wire-flipping prevention jig for winding a square wire voice coil, so as to prevent the wire from flipping during winding and meet the production requirements of the wire-releasing voice coil.

[0004] To solve the above technical problems, a square wire voice coil winding anti-flipping fixture is provided according to the utility model, which includes a base, a bracket, and a guide member. The side wall of the base is penetrated by a wire threading hole, the bracket is fixedly connected to one side of the base, and the guide member is fixedly connected to the bracket. A square groove is provided on the guide member, and the square groove and the wire threading hole are arranged on the same straight line.

[0005] Preferably, a receiving cavity communicating with the threading hole is provided on the top of the base.

[0006] Preferably, ceramic guide sleeves matching the threading holes are inserted at both ends of the threading holes.

[0007] Preferably, a bracket matching the guide member is provided at the top of the bracket, the guide member is provided on the bracket, and both side walls of the bracket are penetrated by a first screw hole connected to the bracket, and the first screw hole is connected to a machine screw abutting against the outer wall of the guide member.

[0008] Preferably, a longitudinal strip groove is provided through the bracket, a second screw hole is provided on the side wall of the base, and a positioning bolt is connected between the longitudinal strip groove and the second screw hole.

[0009] Preferably, a top cover for closing the accommodating cavity is sleeved on the top of the base.

[0010] The beneficial effects of the utility model are as follows: the utility model provides an anti-wire-flipping jig for winding a square wire voice coil, the width of the square groove is set to match the width of the square wire, and when winding, one end of the square wire is passed through the wire hole and the square groove in sequence and then wound around the voice coil frame. During the wire-releasing process, the square wire can be kept in a uniform direction under the guiding effect of the square groove, thereby avoiding twisting of the wire during winding, ensuring that the outer diameter of the coil and the conductor occupancy rate meet the requirements, and reducing the product defect rate.

DETAILED DESCRIPTION

[0015] To make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments.

[0016] Based on the described embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present disclosure.

[0017] refer to Figure 1-3 .

[0018] The utility model provides an anti-flipping jig for winding a square wire voice coil, comprising a base 1, a bracket 2, and a guide member 3. A wire threading hole 10 is provided through the side wall of the base 1, the bracket 2 is fixedly connected to one side of the base 1, and the guide member 3 is fixedly connected to the bracket 2. A square groove 30 is provided on the guide member 3, and the square groove 30 and the wire threading hole 10 are arranged on the same straight line.

[0019] Its working principle is that the width of the square groove 30 is set to match the width of the square wire. When winding, one end of the square wire is passed through the wire hole 10 and the square groove 30 in sequence and then wound around the voice coil frame. During the wire-unwinding process, the square wire can be maintained in a uniform direction under the guiding effect of the square groove 30, avoiding wire twisting during winding, ensuring that the coil outer diameter and conductor occupancy rate meet the requirements, and reducing product defective rate.

[0020] Based on the above embodiment, a accommodating cavity 11 connected to the threading hole 10 is provided on the top of the base 1. Cotton can be filled in the accommodating cavity 11. During the line laying process, the dust on the surface of the square wire can be wiped off by the cotton to ensure that the surface of the square wire is clean.

[0021] Based on the above embodiment, both ends of the threading hole 10 are inserted with ceramic guide sleeves 4 that match the threading hole 10. The ceramic guide sleeve 4 is made of ceramic material with a smooth and wear-resistant surface, which avoids scratching the surface of the square wire and is convenient for replacing the ceramic guide sleeve 4.

[0022] Based on the above embodiment, a bracket 20 matching the guide member 3 is provided at the top of the bracket 2, and the guide member 3 is provided on the bracket 20. Both side walls of the bracket 2 are penetrated by a first screw hole 21 connected to the bracket 20. The first screw hole 21 is connected with a machine screw 5 abutting against the outer wall of the guide member 3, which facilitates the disassembly, assembly and replacement of the guide member 3. By changing the width of the square groove 30, it is suitable for the winding processing of square wires of different widths.

[0023] Based on the above embodiment, a longitudinal strip groove 22 is provided through the bracket 2, a second screw hole 12 is provided on the side wall of the base 1, and a positioning bolt 6 is connected between the longitudinal strip groove 22 and the second screw hole 12 to facilitate the adjustment of the height of the guide member 3 so that the square groove 30 is aligned with the threading hole 10.

[0024] Based on the above embodiment, a top cover 7 is provided on the top of the base 1 for closing the accommodating cavity 11 to prevent foreign matter from falling into the accommodating cavity 11 and contaminating the cotton, allowing the cotton to wipe the surface of the square wire.

[0025] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
