A snap spring may be used to fix the restoring spring 432 to the end of the top rod 431. When the spacing pin 461 of the spacing mechanism 46 is required to be coupled with the spacing groove 462, the abutment piece 452 of the abutment driving mechanism 45 abuts against the push rod 431 to enable the spacing groove 462 on the fixing plate 42 to slide toward the spacing pin 461, thereby limiting or fixing the relative position between the tuning fork assembly 44 and the secondary shaft assembly 31, and further enabling the tuning fork assembly 44 and the secondary shaft assembly 31 to rotate together. When the tuning fork assembly 44 is required to be separated from the secondary shaft assembly 31 to complete the respective tasks, the supporting driving mechanism 45 returns to the original position and is separated from the supporting of the top rod 431, so that the fixing plate 42 slides towards the supporting driving mechanism 45 under the action of the restoring spring 432 of the restoring mechanism 43, and the limiting pin 461 of the limiting mechanism 46 is decoupled from the limiting groove 462, and at this time, the tuning fork assembly 44 and the secondary shaft assembly 31 can rotate respectively.

The wire storage wheel 51 is used for storing a certain number of wires for winding the alpha coil, and the working principle thereof will be described in detail below. The wire clamping device 52 is used for clamping one wire end of the wire, so that the wire can be wound on the wire storage wheel 51 in the process of rotating the tuning fork assembly 44. The wire clamping device 52 comprises a base 521 arranged on the wire storage wheel 51, a T-shaped clamp 522 inserted on the base 521, a cylinder 523 for controlling the movement of the T-shaped clamp 522, and a restoring elastic member 524 arranged between the cylinder 523 and the base 521 and sleeved on the T-shaped clamp 522. The cylinder 523 drives the T-shaped clamp 522 to move up and down to clamp and release the wire. The return spring 524 may be a spring for clamping the wire against the T-clamp 522. The driving torque motor 53 is a special motor with soft mechanical property and wide speed regulation range, and has the working characteristics of outputting power not with constant power but with constant torque, and has soft mechanical property and can be locked. In this embodiment, the driving torque motor 53 may not only drive the wire storage wheel 51 to rotate for storing wires, but also provide a certain torque for paying out the wires on the wire storage wheel 51, so that the paid out wires have a certain tension, thereby being beneficial to winding wires. The wire storage wheel driving mechanism 54 includes a rail device 541 fixed to the frame 10, a bracket 542 provided on the rail device 541, and a driving motor 543 provided on the bracket 542.

The rail device 541 is a prior art, and includes a rail and a slider, but is a technology known to those skilled in the art, and is not described herein. The bracket 542 is fixedly provided on the slider of the rail device 541 so as to be slidable along the rail. An output shaft of the driving motor 543 is connected to the bracket 542 and may be a screw, so that the bracket 542 may be driven to reciprocate along the guide rail, and the wire storage wheel 51 may be driven to reciprocate. In the process of reciprocating the wire storage wheel 51, the wires released by the wire storage wheel 51 are arranged on the mold core 223, so that the purpose of wire arrangement is achieved.
The scissors wire clamping mechanism 60 includes an X-axis sliding mechanism 61 provided on the frame 10, a Y-axis sliding mechanism 62 provided on the X-axis sliding mechanism 61, a Z-axis sliding mechanism 63 provided on the Y-axis sliding mechanism 62, and a tail wire clamping device 64 provided on the Z-axis sliding mechanism 63. The X-axis sliding mechanism 61, the Y-axis sliding mechanism 62, and the Z-axis sliding mechanism 63 are all conventional, and include a rail, a slider, and a driving mechanism, which are well known to those skilled in the art, and will not be described in detail. The X-axis sliding mechanism 61, the Y-axis sliding mechanism 62, and the Z-axis sliding mechanism 63 are used to drive the tail wire clamping device 64 to move along the X-direction, the Y-direction, and the Z-direction, so as to control the wire clamped by the tail wire clamping device 64 to move along the three directions, thereby completing the winding. The tail wire clamping device 64 comprises an air cylinder arranged on the Z-axis sliding mechanism 63, a first clamping jaw fixed on the cylinder body of the air cylinder, and a second clamping jaw fixed on the air cylinder. When the output end of the air cylinder moves, the purpose that the first clamping jaw and the second clamping jaw clamp or loosen the lead can be achieved. When the winding of an alpha coil is completed, the clip clamping mechanism 60 clamps the wire on the hairpin 40, then shears the wire, and finally feeds the wire end of the wire threaded in the hairpin 40 to the wire clamping device 52 of the wire storage mechanism 50, thereby completing the winding of an alpha coil and starting the winding of a new alpha coil.
The control device 70 may be a set of PLCs or a set of central processing units, which control the working states of the main shaft rotating mechanism 20, the secondary shaft rotating mechanism 30, the wire storage mechanism 50 and the wire cutting clamping mechanism 60 through control theory in the prior art such as programming operation. As for the programming language and implementation manner of the control device 70, for example, whether it is through VB or VC or even a net language, it is not in the limitation of the present invention, and those skilled in the art can complete the corresponding programming as long as knowing the idea and working manner of the present invention.
When the wire winding device works, firstly, the wire is wound on the wire storage wheel 51 by threading the wire on the hairpin mechanism 40 and then clamping the wire on the wire clamping device 52 of the wire storage mechanism 50, and the wire storage wheel 51 rotates.
The control device 70 controls the spindle assembly 22 to move in the axial direction thereof so that the mold core 223 is inserted into the mold hole 313. The tuning fork mechanism 40 then winds the wire around the mold core 223 and around the side of the mold core 223 facing the secondary shaft assembly 31. At this time, the rotation driving mechanism 21 is stopped. When the tuning fork mechanism 40 winds around a circle, the rotation driving mechanism 21 rotates the main shaft assembly 22, and the main shaft assembly 22 drives the sub shaft assembly 31 to rotate so as to achieve the purpose that the main shaft assembly 22 and the sub shaft assembly 31 rotate at the same speed. The tuning fork mechanism 40 rotates under the driving of the secondary shaft driving mechanism 33 at the same rotation speed and rotation direction as the main shaft assembly 22 while the main shaft assembly 22 rotates, thereby preventing the wound wire from being scattered. When the spindle assembly 22 rotates, the wire stored on the wire storage wheel 51 is wound on the mold core 223, and meanwhile, the wire storage wheel 51 is driven by the wire storage wheel driving mechanism 54 to reciprocate, so that the purpose of wire arrangement is achieved. When the wire storage wheel 51 makes a linear motion, a wire arrangement can be completed, that is, at least one winding turn is completed along the axial direction of the coil. The above-described winding will complete the winding of one layer of coils in the radial direction of the coils. It is conceivable that the above-described operation is repeated when a plurality of layers are required to be wound in the radial direction of the coil.
