As a key piece of equipment in motor manufacturing, the production speed of a flying fork automatic winding machine is directly related to a company’s production efficiency and cost control. However, increasing production speed is not easy. It is influenced by many factors, including mechanical structure, electrical control, process parameters, equipment stability, and the external environment. Vacuz has conducted a detailed analysis of these factors and proposed common methods for improving the production speed of flying fork automatic winding machines. The optimization results are demonstrated through practical application cases.

I. Key Factors Affecting the Production Speed of Flying Fork Automatic Winding Machines

1. Mechanical Structure Performance

a. Flying Fork Design: The rigidity, weight, and dynamic balance of the flying fork are crucial for stability during high-speed rotation. An improperly designed flying fork is prone to vibration, causing the machine to automatically reduce speed for protection.

b. Drive System: The accuracy and wear of transmission components such as the lead screw, guide rails, and belts directly affect the smoothness of movement. Worn components can cause hysteresis and reduce winding speed.

c. Die Compatibility: The matching of the die to the stator slot shape affects winding efficiency. Die dimensional deviations or burrs can cause wire jamming, requiring speed reduction to ensure quality.

2. Electrical Control Capabilities

a. Servo System Performance: The servo motor’s torque, speed range, and response speed determine the device’s start/stop and speed-changing capabilities. Low-performance servo motors may experience performance bottlenecks at high speeds.

b. Control Algorithm Optimization: The rationality of the speed planning algorithm affects motion smoothness. An unoptimized algorithm can easily trigger overload protection, limiting speed increases.

c. Signal Transmission Latency: Communication latency between the controller and actuator is a major obstacle to speed increases. In high-speed scenarios, a low-latency communication bus is more advantageous.

3. Process Parameter Settings

a. Winding Speed: The wire material, wire diameter, and stator slot configuration collectively determine the safe speed. Thin wires require a reduced speed to prevent breakage.

b. Tension Control: Excessive tension can lead to wire breakage, while too little tension can cause slack in the winding. Dynamic tension control supports higher speeds.

c. Wire Arrangement Density: High-density wire arrangement requires more accurate motion control. Uneven wire arrangement may cause the device to slow down to correct for errors.

4. Equipment Stability and Reliability

a. Vibration and Noise: Increased mechanical vibration and noise during high-speed operation may trigger protective mechanisms and cause shutdowns.

b. Heat Dissipation: Prolonged high-speed operation will cause temperature rise, and insufficient heat dissipation will limit speed increases.

c. Component Lifespan: Frequent starting and stopping accelerates component wear, necessitating a balance between speed and lifespan.

5. External Environment and Operational Factors

a. Power Supply Stability: Voltage fluctuations or frequency deviations affect servo motor performance, leading to speed instability.

b. Temperature and Humidity Control: High temperatures and humidity can soften wire or cause mold expansion, necessitating speed reduction to ensure quality.

c. Operator Skills: Incorrect parameter settings can indirectly limit speed.

II. Common Methods for Improving the Production Speed of Automatic Flying Fork Winding Machines

1. Hardware Upgrade and Optimization

a. Use Lightweight, High-Rigidity Flying Forks: Use carbon fiber or aircraft aluminum alloy to reduce weight while maintaining strength. Optimize dynamic balancing to reduce vibration.

b. Upgrade the Servo System: Use high-torque, high-speed servo motors paired with high-resolution encoders to improve position control accuracy.

c. Improve the drive system: Replace with a linear motor or direct drive system to eliminate mechanical transmission backlash. Use high-precision ball screws or linear guides to reduce friction.

d. Optimize mold design: Use CNC-machined molds to ensure dimensional accuracy, and apply hard chrome plating or nitriding to the mold surface to reduce friction.

2. Electrical Control and Algorithm Optimization

a. Dynamic Speed Planning: Adjust the acceleration and deceleration curves in real time based on the wire and stator characteristics, and introduce a speed look-ahead function to plan the motion path in advance.

b. Multi-Axis Collaborative Control: Synchronize the rotation of the flyer, the movement of the wire arrangement mechanism, and tension control to improve overall motion efficiency.

c. Intelligent Tension Control: Combine force sensors and PID algorithms to dynamically adjust tension, using a magnetic levitation tensioner to eliminate the effects of mechanical friction.

3. Fine-tuning Process Parameters

a. Step-by-Step Speed Control: Set different speeds according to the winding stage, such as using a low speed during the start-up phase to ensure the wire end is fixed, and increasing the speed during the constant speed phase.

b. Tension-Speed Coordination: Establish a tension-speed mapping table to automatically adjust tension based on speed.

c. Wire Tracing Optimization: Use high-frequency wire tracing to reduce the distance between each wire and minimize impact. Introduce a visual inspection system to correct wire tracing deviations in real time.

4. Measures to Enhance Equipment Stability

a. Active Vibration Reduction Technology: Install shock absorbers on the equipment base to suppress high-speed vibration.

b. Efficient Heat Dissipation Design: Use liquid-cooled servo motors or a forced air cooling system to control temperature.

c. Preventive Maintenance: Establish a life monitoring system for key components and conduct regular equipment calibration.

5. External Environment and Operation Management

a. Stable Power Supply: Install an uninterruptible power supply (UPS) and a voltage stabilizer to ensure voltage stability.

b. Temperature and Humidity Control: Control the workshop temperature and humidity to reduce the risk of wire deformation.

c. Operator Training: Conduct regular speed optimization training to improve parameter setting skills. Establish a speed-quality correlation database to guide operations.

In summary, improving the production speed of automatic winding machines for flying forks requires addressing multiple aspects, including mechanical structure, electrical control, process parameters, equipment stability, and the external environment. Through a combination of measures, including hardware upgrades, algorithm optimization, process adjustments, equipment stability enhancement, and operational management, production speed can be effectively increased while ensuring product quality. This provides strong support for motor manufacturers to improve production efficiency and reduce costs.
