Description

Technical Field

[0001] This utility model relates to the field of voice coil skeleton production technology, and in particular to a voice coil skeleton winding device. Background Technology

[0002] Voice coil bobbin winding equipment is a specialized automated device used for precision winding of enameled copper wire onto a voice coil bobbin. It is widely used in the manufacture of electromagnetic drive components such as loudspeakers, linear motors, and micro motors. Its core task is to ensure winding accuracy, consistency, and electrical performance, which directly affects the frequency response, power handling capacity, and reliability of the final product.

[0003] Chinese Patent No. CN221327539U discloses a skeleton voice coil winding device, comprising: a mounting frame on which a first drive mechanism and a second drive mechanism are mounted; a wire feeding mechanism for outputting enameled wire; a rotating shaft rotatably mounted on the mounting frame along its own axis; a winding drum sleeved on the rotating shaft and capable of rotating with the rotating shaft, the outer periphery of the winding drum having a wire clamping arm, the wire clamping arm having a wire clamping structure capable of clamping the enameled wire; and a wire pulling mechanism having a movable wire clamping and cutting structure, the wire clamping and cutting structure having a first movable block and a second movable block that can move closer to or further away from each other, the first movable block having a wire clamping part and a wire cutting part on the side opposite the second movable block, the wire clamping part being closer to the wire feeding mechanism than the wire cutting part. This invention features simplified steps and a high degree of automation in the entire winding process, effectively improving winding efficiency.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: existing voice coil bobbin winding equipment cannot automatically spread the wire during winding, resulting in the wire being wound on the same ground, which easily causes tangling and affects the winding effect. At the same time, it cannot automatically cut the wire after winding, and the bobbin voice coil cannot be quickly disassembled for new winding work after winding. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art where the wire cannot be automatically unwound when it cannot be wound up, and the wire is automatically cut off and replaced with a new voice coil skeleton after winding up.

A connecting block is located on the side of the lead frame, and an electric ejector knife is located on the top of the connecting block. An infrared rangefinder is located on the side of the electric ejector knife. The lead frame moves back and forth under the drive of the wire laying mechanism. A notch is located on the top of the lead frame. The wire is passed through the notch and installed on the winding mechanism. The lead frame drives the wire to move back and forth to achieve flat winding. The infrared rangefinder measures the distance of the passing wire. After the required winding length is reached, the electric ejector knife is activated, and the electric ejector knife ejects the blade to cut the wire.

[0010] Preferably, the cable laying mechanism includes a placement rack and a reciprocating assembly;

[0011] The shelf is positioned on top of the base plate;

[0012] The reciprocating assembly is located on top of the placement frame and is used to drive the lead frame to move back and forth.

[0023] Compared with the prior art, the present invention has the following beneficial technical effects:

[0024] 1. Through the setting of the wire laying mechanism, the second motor drives the lead wire frame to move back and forth. During the movement, the guide wire is laid flat on the skeleton body and wound up. After the infrared rangefinder detects that the wound wire has reached the specified length, it controls the electric ejector knife to cut the wire. This back and forth movement drives the wire to be laid flat, so that each layer of wire is tightly arranged with very small gaps between the wires. This can avoid the local bulges or depressions caused by the accumulation of wire in traditional winding, ensuring that the overall density of the coil is high and the appearance is flat. In addition, the automatic cutting of the wire can avoid the waste of wire and prevent the coil performance from being unstable due to the wire being too long or too short.

[0025] 2. Through the winding mechanism, motor one drives the frame body to rotate through the winding drum, thereby winding the frame body. After the frame body has finished winding, rotate the threaded rod to disengage it from the limit block, and then rotate the support plate two to disengage it from the rotating shaft one. Then, the wound frame body can be disassembled and replaced with a new one. This can quickly dispose of the wound frame voice coil without spending too much time on disassembling and installing a new frame voice coil, thus affecting the winding efficiency.

[0037] Example 2

[0038] like Figures 1-4 As shown, this utility model proposes a voice coil bobbin winding device. Compared with Embodiment 1, this embodiment details the structure of the winding mechanism.

[0039] The winding mechanism includes a support plate 201, a take-up assembly, and a disassembly assembly. The support plate 201 is located on the top of the base plate 1. The take-up assembly is located on the support plate 201 and is used to take up the wire of the voice coil.

Then align the connecting shaft 208 with the first rotating shaft 203 and release it. The second support plate 209 moves under the action of the spring 215, thereby locking the connecting shaft 208 into the first rotating shaft 203. After installation, pass the wire through the lead frame 308 and install it on the frame body 207. Then start the first motor 202 and the second motor 302. Motor 202 drives the rotating shaft 203 to rotate. The rotating shaft 203 drives the winding drum 206 to rotate through the rotating frame 205. The winding drum 206 drives the frame body 207 to rotate. At the same time, motor 302 drives the rotating shaft 304 to rotate. The rotating shaft 304 drives the power rod 305 to rotate. When the power rod 305 rotates, it drives the moving rod 306 to move back and forth. The moving rod 306 drives the sliding block 307 to slide back and forth in the fixed frame 312, thereby driving the lead frame 308 to drive the wire to be laid flat and wound back and forth. During the winding process, the infrared rangefinder 310 measures the distance of the passing wire. After the winding length requirement is reached, the electric ejector knife 311 is activated.
