Grooves are provided on the multiple guide wheels, which can guide the wire and prevent the wire from shifting during movement. The guide tubes 18 on the two limit blocks 16 also play a role in guiding the wire, and at the same time can prevent the wire from bending or deforming, ensuring the flatness of the wire.

The motor four 47 drives the rotating shaft 48 to rotate, and the rotating shaft 48 synchronously drives the transformer coil skeleton to rotate, so as to wind the coils in the wire tube one 20 and the wire tube two 39 on the transformer coil skeleton. The X-axis linear module three 41, the Y-axis linear module three 43, and the Z-axis linear module three 45 cooperate with each other to enable the rotating shaft 48 to move in any direction, increasing the mobility of the rotating shaft 48, so that the rotating shaft 48 can not only match the movement mode of the wire tube one 20 and the wire tube two 39, but also pick up materials on the feeding machine 5 and discharge materials at the discharging machine 6, thus realizing automatic operation and eliminating the need for manual transfer of the transformer coil skeleton by workers.

[0052] After the wire moves a certain number of layers during winding on the transformer coil skeleton, the rotating shaft 48 moves the transformer coil skeleton between the two groups of tension rollers 72, so that the insulating tape fits with the outer wire. Then the rotating shaft 48 drives the transformer coil skeleton to rotate, and the insulating tape is wound on the transformer coil skeleton. After the insulating tape is wound, the air cylinder one 73 drives the pressing block 75 to rise to press the insulating tape, and then the air cylinder two 76 drives the cutting knife 78 to rise to cut the insulating tape, so that the rotating shaft 48 can move to the wire tube one 20 and the wire tube two 39 again for the next round of wire winding. The motor five 79 cooperates with the lead screw 70 to drive the sliding seat 710 to move, so that the sliding seat 710 moves along the slide rail two 711 and synchronously drives the two clamping plates 716 to move, thereby changing the clamping position of the clamping plates 716 on the insulating tape, so that the insulating tape can be wrapped on the outside of wires with different thicknesses.
