in the first step, the second stepping motor 8 in the wire feeding mechanism drives the driving clamping roller to rotate, and the driving clamping roller and the driven clamping roller convey the raw material wire downwards so that the raw material wire passes through the wire hole 17. When winding the first coil, the raw material wire needs to be manually threaded through the lead hole 17, and when winding the subsequent coils, since the raw material wire is always in the lead hole 17, manual threading is not needed.
In the second step, the piston rod of the first cylinder 19 in the thread end pulling mechanism extends out to lift the flare-shaped tube 23 upwards, so that the thread end passing through the thread leading hole 17 enters the vertical guide tube 22 through the flare-shaped tube, and then the piston rod of the second cylinder 21 extends into the vertical guide tube 22 to compress the thread end. The piston rod of the first cylinder 19 is then retracted a distance, pulling the raw wire down between the presser plate of the thread end hold-down mechanism and the spindle.

The driving motor of the electric wrench is a servo motor, the controllability is good, the rotation number of the bolt can be accurately controlled, and then the force for compressing the wire ends can be accurately controlled.
Fourth, the piston rod of the second cylinder 21 in the wire end pulling mechanism is retracted to loosen the wire end, and the piston rod of the first cylinder 19 is retracted to return.
And fifthly, a third stepping motor 15 in the wire feeding mechanism drives the first screw rod to rotate, so that the sliding block 11 moves downwards, and the raw material wire is separated from the driving clamping roller, and the driven clamping roller becomes a guide wheel at the moment. Meanwhile, a magnetic damper 6 in the wire feeding mechanism acts to apply a set tension to the raw wire so as to ensure the winding quality of the coil.
Sixthly, the first stepping motor 3 drives the main shaft to rotate, and the first linear driver 5 drives the L-shaped bracket 4 to reciprocate, so that raw material wires are wound on the coil sleeve; in particular embodiments the rotational speed of the first stepper motor 3 and the speed of movement of the L-shaped support 4 are set according to the coil specifications. During winding, the glue gun 35 extrudes and coats the insulating glue on the coil, and the electric cylinder 34 can control the distance between the gun nozzle of the glue gun and the coil, so that the gun nozzle height of the glue gun can be changed along with the change of the layer number of the coil; and when gluing, the fourth linear driver drives the second sliding seat to move along with the L-shaped bracket, and the hot air blower works to blow hot air to the coil, so that the insulating glue coated on the coil is air-dried.
Seventh, after the winding of the coil is completed, the third linear driver 33 drives the second support plate to move, so that the electric scissors 32 move to the tail, and then the electric scissors work to cut the tail.
Eighth, the fifth linear driver drives the third supporting plate to move along the main shaft, the semicircular annular pushing plate pushes down the wound coil from the coil sleeve 45, the coil falls into the inclined discharge groove 37 and is discharged into the receiving frame, and therefore winding operation of one coil is completed. The coil winding operation can be continuously performed by repeating the steps one to eight.

And take broken string alarming function's transformer coil coiling machine in this embodiment, it is through setting up broken string alarm mechanism control wire winding process, and the raw materials wire rod in the drum bypasses tension sensor, and tension sensor detects wire winding tension, and when raw materials wire rod fracture appears, tension that raw materials wire rod applyed in tension sensor can diminish suddenly, and tension sensor will detect wire rod fracture signal input audible alarm, audible alarm just sends out the alarm, can in time remind the staff to handle wire rod fracture problem. The wire breakage alarm mechanism replaces manual monitoring of the wire winding process, so that the labor intensity of workers can be greatly reduced.
And when winding, the interlayer insulation gluing mechanism can glue along with the wire feeding mechanism, so that the insulation performance of the coil is enhanced, and the interlayer gluing is automatically finished. Meanwhile, after coil winding is completed, the semicircular pushing plate is driven by the fifth linear driver to move along the main shaft, the semicircular pushing plate pushes off the coil on the main shaft, the coil falls into the inclined discharging groove below from the main shaft, and the inclined discharging groove discharges the coil into the receiving frame, so that automatic discharging is realized, and winding production efficiency of the coil is further improved.
