What are the common problems encountered with automatic iron core winding machines?

1、 The positive and negative pole suction plates of the automatic iron core winding machine have not yet reached the supply guide plate before releasing the pieces.
Reason: ① Vacuum damage, incorrect insertion of trachea (front, back or left, right); ② Polar suction confirms poor contact of the sensor.
Solution: ① Replace the trachea; ② Use a multimeter to check if the signal wire is broken and if the sensor is damaged → replace the sensor.
2、 Fault: Automatic mode, pressing the start button is ineffective.
Reason: ① The automatic/manual conversion button or start button is broken; ② The length parameter of the diaphragm is not set.
Solution: ① Replace the switch button; ② Set the parameters.
3、 Fault: The positive CV motor is not turning.
Reason: ① The jog parameter setting is too small; ② Driver parameters not set properly or in alarm state; ③ The motor power cord is not properly connected.
Solution: ① Increase the parameters; ② Set the parameters or shut down and restart → replace the drive; ③ Connect the power cord properly.
4、 Fault: The positive and negative electrodes RB do not rise after dropping the suction plate.
Reason: Pole suction confirms that the sensor has input but no output.
Solution: Use a multimeter to check if the output line is conductive → replace the sensor.
5、 Fault: Negative CV motor overheating alarm.
Reason: ① The setting current parameters of the thermal relay are not set properly or the thermal relay is damaged; ② The bearings or coils on the internal gears of the CV motor are damaged and overloaded.
Solution: ① Set the current setting parameters or replace the thermal relay; ② Replace the motor.
6、 Fault: The diaphragm unwinding motor is abnormal.
Reason: ① Driver abnormal alarm; ② The power cord is disconnected.
Solution: ① Shut down and restart; ② Connect the power cord properly.
7、 Fault: The speed of the diaphragm unwinding motor is too fast and cannot be adjusted slowly.
Reason: ① The potentiometer is broken; ② The speed control circuit board is damaged.
Solution: ① Use a multimeter to check if the potential is damaged first → Replace the potentiometer ② Replace the circuit board.
8、 Fault: The tension claw has reached the lower limit, and the sensor has sensed it but cannot reset or disconnect.
Reason: ① Tension claw linkage confirmation sensor has input but no output; ② The sensor signal line is connected in reverse between normally open and normally closed.
Solution: ① First use a multimeter to detect a broken signal line → replace the sensor; ② Swap the signal line.
9、 Fault: The needle winding motor does not rotate.
Reason: ① Motor driver power switch tripped; ② The setting of the tension claw variable speed parameter is too small; ③ The tension claw retreat position parameter of the iron core winding machine is set too high; ④ Driver damage; ⑤ The motor power cord has come loose.
Solution: ① Close the power switch; ② Adjust parameters; ③ Adjust parameters; ④ Replace the drive; ⑤ Connect the power cord properly.
10、 Fault: The negative CV motor does not rotate.
Reason: ① Fiber optic induction is not set properly and has been connected; ② The main contact of the thermal relay is damaged; ③ The starting capacitor is damaged.
Solution: ① Set the fiber parameters properly; ② Replace the thermal relay; ③ Replace the capacitor.
11、 Fault: The product discharge motor does not rotate.
Reason: ① The motor power cord of the iron core winding machine is connected incorrectly or the power cord is disconnected; ② The motor is stuck and unable to rotate ③ The internal gear bearings of the motor are damaged.
