In one embodiment, the voice coil sleeving feeding and positioning manipulator can be matched with a winding machine for use, and the structural design principle is as follows: one end of an eccentric shifting fork 14 is connected with a voice coil overturning feeding motor 11, the other end of the eccentric shifting fork 14 is connected with a voice coil feeding sliding rail 17 through a double-roller shaft 15, two rollers 16 are installed in the double-roller shaft 15 in parallel, one roller 16 can slide in an eccentric track 13 along with the movement of the eccentric shifting fork 14, and the other roller 16 is installed in a slotted hole at one end of the eccentric shifting fork 14 connected with the voice coil feeding sliding rail 17, so that the voice coil overturning feeding motor 11 which rotates forwards and backwards drives the voice coil feeding sliding rail 17 to move forwards and backwards, rotate annularly, move up and down and the like through the double-roller shaft 15. When the voice coil feeding slide rail 17 moves, all components connected and assembled with the demolding shaft seat mounting plate 20 can be driven to synchronously move through the demolding shaft seat mounting plate 20, namely, the voice coil sleeving mechanism 2 can move forwards and backwards, circularly rotate, lift and the like under the driving of the voice coil overturning feeding motor 11. The voice coil shaft center 21 is fixedly arranged at the center of the side surface of the demoulding shaft seat mounting plate 20, when the voice coil sleeving and taking mechanism 2 is driven by the voice coil feeding mechanism 1 to be close to a winding main shaft of a winding machine, a voice coil demoulding sleeve 29 in the voice coil sleeving and taking mechanism 2 can expose a longer voice coil shaft center 21 when being pushed by a voice coil demoulding cylinder 25 to move backwards, so that the main shaft of the winding machine can conveniently sleeve a coil (voice coil) 7 subjected to winding on the voice coil shaft center 21, and the operation of sleeving and taking the coil 7 is finished; when the voice coil demolding sleeve 29 in the voice coil sleeving mechanism 2 moves forwards under the pushing of the voice coil demolding cylinder 25, the coil 7 can be pushed off from the voice coil shaft center 21, so that demolding of the coil 7 can be realized; when the voice coil axis 21 of the voice coil sleeving mechanism 2 sequentially passes through the thread end hairbrush 4 and the thread end straightening clamping finger cylinder 5 in the process of rotating from top to bottom under the driving of the voice coil feeding mechanism 1, the thread end hairbrush 4 can straighten and straighten the thread end in the coil 7 which is drawn through the voice coil sleeving mechanism and sleeved on the voice coil axis 21, and the thread end straightening clamping finger cylinder 5 can clamp the thread end straightened or straightened by the thread end hairbrush 4, so that preparation is made for the subsequent coil 7 with the thread end adhered on a membrane. When the hollow rotating shaft 205 in the voice coil sleeving mechanism 2 is driven to rotate by the coil rotating angle motor 203, the rotating hollow rotating shaft 205 can drive the coil wiring cylinder 208 and the coil wiring clamp finger cylinder 209 to synchronously rotate, the rotating angle sensor 207 is matched with the rotating angle limiting plate 206, and the hollow rotating shaft 205 stops rotating when the rotating angle sensor 207 senses the two ends of the rotating angle limiting plate 206 in the rotating process, so that the precision of the rotating angle is ensured to be high; the hollow rotating shaft 205 can drive the wire connector wiring cylinder 208 and the wire connector clamping finger cylinder 209 which are connected and assembled with the hollow rotating shaft to synchronously rotate when rotating; the wire connecting cylinder 208 can clamp the wire of the wire straightened by the wire straightening clamp finger cylinder 5 when pushing the wire connecting clamp finger cylinder 209 forward (namely, the wire connecting clamp finger cylinder 209 can clamp the wire by taking over the wire straightening clamp finger cylinder 5). Because one side of the voice coil positioning mechanism 6 is provided with a turntable, the edge of the turntable is provided with a plurality of voice coil jigs 68 at equal intervals, one side of each voice coil jig 68 is provided with a wire end positioning block 69, a diaphragm (vibrating membrane) is firstly placed on each voice coil jig 68, and when the voice coil jigs 68 rotate to be right above a vacuum joint 67 in the voice coil positioning mechanism 6 along with the rotation of the turntable, the wire end positioning blocks 69 also rotate to be right above a wire end spring pin ejector rod 65 along with the rotation of the turntable; when the vacuum connector 67 moves upwards under the drive of the vacuum connector jacking cylinder 63, the vacuum connector 67 can be in sealing butt joint with the voice coil jig 68, and when the vacuum connector 67 vacuumizes the voice coil jig 68, the diaphragm can be sucked on the voice coil jig 68, so that the diaphragm can be automatically positioned; when the voice coil shaft center 21 in the voice coil sleeving mechanism 2 is sleeved with the coil 7 from the winding shaft of the winding machine, the voice coil shaft center can rotate to the upper surfaces of the voice coil jigs 68 under the driving of the voice coil overturning feeding motor 11, and when the voice coil demolding sleeve 29 moves forward under the driving of the voice coil demolding cylinder 25, the coil 7 (i.e. the voice coil) can be separated from the voice coil shaft center 21 to the upper surfaces of the voice coil jigs 68, so that the positioning of the coil 7 and the diaphragm can be automatically completed. When the thread end spring pin ejector rod 65 is driven by the pressing plate opening cylinder 62 to lift upwards, the thread end spring pin 601 in the thread end positioning block 69 can be lifted, and the lifted thread end spring pin 601 can enable the thread end pressing plate 602 and the thread end positioning block 69 to be opened; when the wire head jointing clamp finger cylinder 209 in the voice coil sleeving mechanism 2 rotates along with the hollow rotating shaft 205 and is driven by the wire head rotating angle motor 203, the wire head clamped by the wire head jointing clamp finger cylinder can be driven to synchronously rotate, so that the wire head can be brought between the wire head positioning block 69 and the wire head pressing plate 602 in an open state, then the pressing plate opening cylinder 62 drives the wire head spring pin ejector rod 65 to reset downwards, so that the problem of jacking the wire head spring pin 601 is solved, the wire head spring pin 601 can be driven to move downwards under the action of self gravity to reset, the wire head pressing plate 602 can be synchronously moved downwards, and the downwards moved wire head pressing plate 602 can press the wire head on the wire head positioning block 69, and at the moment, the wire head positioning operation on the coil 7 of the diaphragm is completed. The whole structure design of the coil winding device realizes a series of operations such as automatically winding the coil, automatically rotating and transferring the wound coil, automatically straightening the coil end of the coil, automatically clamping the straightened coil end, automatically connecting the straightened coil end between different pneumatic cylinders, automatically positioning the diaphragm, automatically demolding the wound coil and placing the coil on the voice coil jig 68, automatically positioning the diaphragm and the coil, automatically positioning the coil end and the coil, and the like, and the series of operations are performed without the participation of hands, so that the coil winding device has the advantages of high working efficiency, high positioning precision and high productivity, and not only effectively solves the problems of low working efficiency, poor positioning precision, high labor intensity of workers and high labor cost of enterprises caused by the traditional manual operation mode for feeding and swinging the coil, but also solves the problems of large deviation of the center positioning concentricity of the voice coil and the diaphragm and large fitting distance of leads (the coil end) and the diaphragm.
