[0035] The tail wire cutting device 600 is connected to the wire outlet end of the winding device 300 and is used to cut the tail end of the core wire in the tail wire cutting channel 320 .

[0036] In the present invention, two core wires are wound on the same magnetic ring as an example for explanation. Correspondingly, the thread-on device 200 provides two core wires through two different workstations, or two sets of thread-on devices 200 can be used to provide two core wires. The wire feeding device 500 and the tail wire cutting device 600 are both provided with two sets. The working process is as follows:

[0037] 1) The wire feeding device 200 provides two core wires which are respectively sent to two sets of wire feeding devices 500. Each set of wire feeding devices 500 is connected to the wire inlet end of the winding device 300 (the wire inlet end of the winding channel 310) through a wire tube. The winding channel 310 is ring-shaped in the horizontal direction, and the magnetic ring is in the vertical direction and can rotate. Through the rotation of the magnetic ring and the continuous rotation of the core wire in the winding channel 310, the core wire is finally wound on the magnetic ring;

[0038] 2) In the cutting of the head end of the core wire, after the winding is completed, one of the two sets of wire feeding devices 500 is controlled to work for a period of time, and the core wire controlled by the set of wire feeding devices 500 is sent forward for a distance, so that the length of the core wire is longer than that of the other core wire, so that the head ends of the two core wires have different lengths, and finally the head wire cutting device 700 is used for cutting;

[0039] As a preferred embodiment of the wire feeding device 500, the wire feeding device 500 includes a mounting seat 510, a first driving assembly 520, a first wire feeding wheel 530 and a second wire feeding wheel 540. The first wire feeding wheel 530 and the second wire feeding wheel 540 are relatively arranged on the mounting seat 510 and have a spacing to form a wire feeding channel 550. The core wire is passed through the wire feeding channel 550. The first driving assembly 520 is connected to the first wire feeding wheel 530 or the second wire feeding wheel 540 to drive the first wire feeding wheel 530 or the second wire feeding wheel 540 to rotate; specifically, the first driving assembly 520 drives the first wire feeding wheel 530 or the second wire feeding wheel 540 to rotate, so that the core wire is pushed forward under the friction of the first wire feeding wheel 530 and the second wire feeding wheel 540, and then enters the wire tube. In one embodiment, the first driving assembly 520 is configured as a motor, and is further preferably a stepping motor. The length of the core wire pushed forward can be controlled by controlling the rotation of the stepping motor.

[0040] 3) Before the tail end of the core wire is cut, the winding channel 310 and the tail wire cutting channel 320 are first switched through the channel switching device 400. As a preferred embodiment of the channel switching device 400, the channel switching device 400 includes a second driving component 410 and a rotating block 420; the second driving component 410 is arranged on the frame 100; the rotating block 420 is rotatably arranged on the frame 100 and connected to the output end of the second driving component 410, and a docking channel 421 is arranged on the rotating block 420; the second driving component 410 can drive the rotating block 420 to rotate to a first direction so that the docking channel 421 docks with the winding channel 310; or it can drive the rotating block 420 to rotate to a second direction so that the docking channel 421 docks with the tail wire cutting channel 320.

[0041] Specifically, after the core wire is wound, the second drive assembly 410 drives the rotating block 420 to rotate to the second direction, so that the docking channel 421 docks with the tail wire cutting channel 320, and at the same time closes the winding channel 310, so that the tail end of the core wire does not enter the winding channel 310 but enters the tail wire cutting channel 320, waiting for the tail wire cutting device 600 to cut the tail end of the core wire; in one embodiment, the second drive assembly 410 is set to a first cylinder.

[0042] 4) In the cutting of the tail end of the core wire, as a preferred embodiment of the tail wire cutting device 600, the tail wire cutting device 600 includes a third drive assembly 610 and a cutting knife 620; the third drive assembly 610 is arranged on the frame 100; the cutting knife 620 is movably arranged on the frame 100 and connected to the output end of the third drive assembly 610; the third drive assembly 610 can drive the cutting knife 620 to extend into the tail wire cutting foot channel 320 to cut the tail end of the core wire in the tail wire cutting foot channel 320; preferably, the third drive assembly 610 is set as a second cylinder; in one embodiment, the tail wire cutting device 600 is set as 2 groups and is arranged at intervals along the length direction of the tail wire cutting foot channel 320 in the horizontal direction, so that the tail ends of the core wires of different lengths can be cut. In a further embodiment, 3 groups, 4 groups, etc. can also be set, and more tail ends of the core wires of different lengths can be cut through the cooperation of multiple tail wire cutting devices 600.

[0044] 6) A fully automatic winding machine capable of cutting wire pins of different lengths further comprises a vacuum recovery device 900 connected to the tail wire cutting channel 320 for recovering the cut wire pins.

[0045] 7) The advantage of the present invention is that the above structure can complete the fully automatic winding of the magnetic ring on one device, and the head end and the tail end of the core wire on the magnetic ring have different lengths to meet the subsequent shelling and foot binding requirements.
