Furthermore, the wire wiping wheel is an I-shaped hub, and cotton fibers are filled in the middle of the hub.

Further, the sensor is a pressure sensor or a light sensor.

The invention has the advantages that:

(1) the invention is designed with the wire wiping wheel, so that the copper wire is automatically wiped by the cotton fiber on the wire wiping wheel to remove dust and dirt before entering the winding, and the problem of poor winding performance caused by unclean copper wire is avoided.

(2) The invention designs a mode of providing stable tension for a copper wire by utilizing a hanging needle and a hanging needle spring, wherein the hanging needle can vertically move upwards under the pulling of a winding machine, and the hanging needle spring at the bottom of the hanging needle can make the hanging needle move downwards due to elasticity, so that the hanging needle can move up and down back and forth, the tension of the copper wire is changed, and the copper wire is more flat when being wound.

(3) According to the invention, the positioning shaft is designed at the foremost end of the rack and can vertically move up and down according to requirements, so that the angle of a copper wire entering the winding machine can be adjusted, the copper wire enters the winding machine in a horizontal state, and the winding performance is better.

(4) According to the invention, the sensor is designed at the top of the hanging needle, when the copper wire is disconnected, the hanging needle loses the tensile force of the copper wire and falls on the hanging needle frame, at the moment, the sensor is triggered to start the alarm to give an alarm, and meanwhile, a signal is sent to the winding machine to stop winding, so that the occurrence rate of defective products is reduced.
