[0036] Working principle: After the operator presses the start button on the device control interface, the PLC control system issues an automatic heating start command. First, the induction heating coil in the induction heating box 34 of the induction heating device 3 is powered on, and the air pump 131 and the winding and collecting mechanism air pump 511 are powered on for pressurization work.

The servo motor 84 of the ball screw nut pair type wire arranging device 8 is started, driving the reciprocating wire arranging mechanism 88 and the wire arranging optical rod 86 to achieve wire reciprocating wire arranging. When the limit stop 87 of the ball screw nut pair type wire arranging device 8 contacts the limit switch 85 of the ball screw nut pair type wire arranging device 8, the limit switch 85 sends a signal to the PLC control system 7. The PLC control system 7 receives the signal from the limit switch 85 and issues a control signal for the servo motor 84 of the ball screw nut pair type wire arranging device 8 to reverse. When the limit stop 87 of the ball screw nut pair type wire arranging device 8 contacts another limit switch 85 of the ball screw nut pair type wire arranging device 8, the limit switch 85 sends a signal to the PLC control system 7. The PLC control system 7 receives the signal from the limit switch 85 and issues a control signal for the servo motor 84 of the ball screw nut pair type wire arranging device 8 to rotate forward. This process is repeated until the induction heating treatment process of a box of wires is completed.
