Lithium Battery Winding Machine Failure And Maintenance

Structure of lithium battery winder:
Lithium battery winding machine is an automatic equipment, which is mainly composed of core winding, winding system, winding system, battery tabs welding system, tension control device, deviation correction system, PLC control, etc.

The working principle and function of each structure of lithium battery winding machine:
1. Core Core: As a core part of the whole process, core core plays a vital role on this equipment. It is mostly made of aluminum or steel, and the surface is coated with nickel or chromium to enhance its corrosion resistance.
2. Winding system: This system is the core part of the equipment, which is composed of servo motor, reducer and drum. With precise servo motor control, the material is wound according to a set path.
3. Winding system: When the winding is completed, the winding system will retract the reel for the next use.
4. Battery tabs welding system: During the winding process, the battery tabs welding system works at the same time to accurately weld the tabs and foils.
5. Tension control device: The function of this device is to control the tension of the material throughout the process to ensure consistency.
6. Guiding system: The function of the guiding system is to maintain the precise alignment of the material during the winding process.

Lithium battery winding machine general failure and maintenance methods:

1. Failure: The positive and negative electrode suction plates of the winding machine have not yet reached the supply guide plate after suction.

• Reasons: (1) Vacuum destruction trachea inserted incorrectly (front and back or left and right); (2) The electrode piece suction confirms that the sensor is in poor contact.
• Solution: (1) Swap the air pipe; (2) Use a multimeter to check whether the signal line is broken and whether the sensor is damaged→ replace the sensor.

2. Fault: hit manual, pressing the start button is invalid.

• Reasons: (1) The manual conversion button or start button is bad; (2) The length parameter of the lower diaphragm is not set.
• Solution: (1) replace the switch button (2) set the parameters.

3. Fault: the positive CV motor does not turn.

• Reasons: (1) The jogging parameter setting is too small; (2) The drive parameters are not set or in the alarm state; (3) The motor power cord is not connected well.
• Solution: (1) Increase the parameters; (2) Set the parameters or turn off and start → replace the drive; (3) Connect the power cord.

4. Failure: positive and negative RB does not rise after falling the suction sheet.

• Reason: The pole piece sucks to confirm that the sensor has input or output.
• Solution: Use a multimeter to detect whether the output line is on → replace the sensor.

5. Fault: negative CV motor overheating alarm.

• Reasons: (1) The thermal relay setting current parameters are not set or the thermal relay is damaged; (2) The bearing or coil on the internal gear of the CV motor is damaged and overloaded.
• Solution: (1) Set the current setting parameters or replace the thermal relay; (2) Replace the motor.

6. Fault: abnormal diaphragm unwinding motor.

• Reasons: (1) Drive abnormal alarm; (2) The power cord is broken.
• Solution: (1) Shut down and start again; (2) Connect the power cord well.

7. Fault: the speed of the diaphragm unwinding motor is too fast and not slow.

• Reasons: (1) The potentiometer is bad; (2) The speed adjustment circuit board is bad.
• Solution: (1) first use a multimeter to detect whether the potential is damaged → replace the potentiometer (2) replace the circuit board.

8. Failure: the tension claw has reached the lower limit, and the sensor has sensed but cannot be reset or cut away.

• Reasons: (1) The tension claw linkage confirms that the sensor has input or output; (2) The sensor signal line is normally open and normally closed.
• Solution: (1) First use a multimeter to detect that the signal line is broken→ replace the sensor; (2) Swap the signal line.

9. Failure: the needle coil motor does not rotate.

• Reasons: (1) The motor drive power switch tripped; (2) The variable speed parameter of the tension claw is set too small; (3) The retreat parameter of the tension claw of the winding machine is set too large; (4) The drive is damaged; (5) The motor power cord falls off.
• Solution: (1) Close the power switch; (2) Adjust parameters; (3) Adjust parameters; (4) Replace the drive; (5) Connect the power cord well.

10. Failure: The negative CV motor does not rotate.

• Reasons: (1) The optical fiber induction is not set up and turned on; (2) The main contact of the thermal relay is damaged; (3) The starting capacitor is bad.
• Solution: (1) Set the optical fiber parameters; (2) Replace the thermal relay; (3) Replace the capacitor.

11. Failure: the product discharge motor does not turn.

• Reasons: (1) The power cord of the winding machine motor is connected incorrectly or the power cord falls off; (2) The motor is stuck and cannot be moved (3) The internal gear bearing of the motor is damaged.
