Description

Technical Field

[0001] The utility model relates to voice coil production equipment, in particular to a modular structure of a voice coil winding machine. Background Art

[0002] The voice coil is the core component of the speaker. The production of the voice coil includes processes such as frame forming, winding, and stickers. As electronic devices become more and more popular, the market demand for speakers is also increasing, resulting in an increasing demand for voice coil production capacity. Therefore, the industry has gradually begun to popularize automated equipment for the production of voice coils.

[0003] For the voice coil winding process, there are usually a wire arrangement mechanism for pre-arranging the wires, a spindle mechanism for winding the wires arranged by the wire arrangement mechanism onto the voice coil frame, and a wire clamping mechanism for cutting the wound voice coil.

[0004] The applicant has found in practice that although the above-mentioned wire arrangement mechanism, spindle mechanism, and wire clamping mechanism have direct implementation solutions in the prior art, it takes a lot of work time to assemble the production line, especially in the trial and debugging of the machine. The reason is that the prior art mostly mixes the structures of the above-mentioned wire arrangement mechanism, spindle mechanism, and wire clamping mechanism together, which are extremely easy to affect each other during debugging. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art, the utility model provides a modular structure of a voice coil winding machine, which specifically adopts the following technical solutions.

[0006] The modular structure of the voice coil winding machine includes a wire arrangement mechanism for pre-arranging the wires used for winding the voice coil, a spindle mechanism for winding the wires arranged by the wire arrangement mechanism onto the voice coil frame, and a wire clamping mechanism for cutting the wires of the wound voice coil. It also includes a workbench. The wire arrangement mechanism, the spindle mechanism, and the wire clamping mechanism are respectively made into independent modules and assembled on the workbench respectively. The wire clamping mechanism is located between the wire arrangement mechanism and the spindle mechanism.

[0007] Furthermore, the spindle mechanism includes a first base, a first linear module arranged on the first base, a winding spindle driven by the first linear module to move axially, and a first servo motor driving the winding spindle to rotate, and a collet for clamping a gauge jig is provided at the end of the winding spindle; the first base is provided with a plurality of first long holes whose length direction is parallel to the axial direction of the winding spindle, and the first base is fastened to the workbench by bolts passing through the first long holes.

[0008] Furthermore, the wire arrangement mechanism includes a second base, a second linear module arranged on the second base, and a wire arrangement frame driven by the second linear module to move parallel to the axial direction of the winding spindle. The wire arrangement frame is provided with a wire wheel whose axial direction is parallel to the winding spindle, and a tin groove located on the side of the wire wheel facing the winding spindle. The wire used for winding the voice coil turns horizontally after passing through the wheel edge of the wire wheel, and then passes through the tin groove and is led to the winding spindle; the second base is provided with a plurality of second long holes whose length direction is perpendicular to the axial direction of the winding spindle, and the second base is fastened to the workbench by bolts passing through the second long holes.

[0009] Furthermore, the wire clamping mechanism includes a third base, a swing arm arranged on the third base, and a third servo motor that drives the swing arm to swing on the radial plane of the winding spindle. Pneumatic fingers are provided at the end of the swing arm, and blades for shearing are provided at the inner edges of the pneumatic fingers facing each other.

[0010] Compared with the prior art, the beneficial effect of the utility model is that the wire arrangement mechanism, the spindle mechanism and the wire clamping mechanism are respectively made into independent modules, which can cooperate with each other in assembly line operation and can be debugged separately, thereby reducing the difficulty of machine testing and debugging and significantly reducing the time investment in debugging.
