Ensuring the stability and safety of automatic motor stator winding machines requires a comprehensive approach encompassing equipment design, operating procedures, maintenance, and safety protection. Here are some common and practical methods covering mechanical, electrical, operational, and management aspects, which Vacuz will briefly introduce:
I. Improving Mechanical Stability
1. Optimizing Equipment Structure and Materials
Strengthening the Frame: Using high-strength metal to construct the frame reduces vibration and deformation. For example, adding reinforcing ribs to key areas such as the winding head and wire laying mechanism improves overall rigidity.
Simplifying the Transmission System: Reducing the number of moving parts and using direct drive instead of complex transmission chains lowers the risk of mechanical failure.
Selecting High-Precision Components: Such as high-rigidity lead screws, low-backlash reducers, and wear-resistant guide rails, ensures smooth movement and repeatability.
2. Regular Calibration and Adjustment
Dynamic Balance Calibration: Performing dynamic balance tests on rotating parts eliminates vibration during high-speed rotation, preventing equipment shaking or excessive noise caused by centrifugal force.
**Wire Laying Mechanism Alignment:** Regularly check the synchronization of the wire laying mechanism and the winding shaft to ensure neat wire arrangement and prevent wire overlap or breakage due to wiring misalignment.
**Die Wear Inspection:** Die wear can cause mismatch between the stator slot and the wire, leading to uneven winding or wire jamming. Wearing dies must be replaced regularly, and the replacement cycle recorded.
3. **Vibration Damping and Anti-Loosening Design:**
**Installation of Vibration Damping Pads:** Install rubber vibration damping pads between the equipment base and the ground to absorb vibration and reduce the impact on the surrounding environment.
**Anti-Loosening Screws and Locking Devices:** Use anti-loosening screws or lock nuts on critical components to prevent loosening and malfunctions after long-term operation.
II. Ensuring Electrical Safety
1. Electrical System Protection
**Grounding Protection:** Ensure reliable grounding of metal components such as the equipment casing, motor, and control cabinet to prevent leakage and electric shock.
**Overload Protection:** Install thermal relays or electronic overload protectors in the motor drive circuit. When the current exceeds the rated value, the power supply is automatically cut off to prevent motor burnout.
1. Short Circuit Protection: Use fuses or circuit breakers to protect the circuit from short circuits that could cause fires or equipment damage.
2. Insulation and Withstand Voltage Testing
Regular Insulation Testing: Use a megohmmeter to test the insulation resistance of motor windings and control circuits to ensure compliance with safety standards.
Withstand Voltage Testing: Perform withstand voltage tests on high-voltage components (such as transformers and capacitors) to verify their insulation performance and prevent breakdown.
3. Electromagnetic Compatibility (EMC) Design
Interference Shielding: Install metal shielding covers on servo drives, PLCs, and other control components to reduce the impact of electromagnetic interference on equipment operation.
Filtering: Install filters at the power input to suppress harmonics and voltage spikes in the power grid, protecting the electrical components of the equipment.
III. Standardized Operating Procedures
1. Operator Training
Safe Operating Procedures: Develop detailed operating manuals that clearly define the steps for starting, running, stopping, and emergency stopping. Operators must be familiar with the equipment’s performance and safety precautions.
1. **Simulation Exercises:** Regularly organize emergency drills, such as simulating wire breakage, wire jamming, and leakage, to train operators in rapid response and proper handling.
2. **Parameter Setting and Monitoring:** Proper parameter settings: Adjust winding speed, tension, number of turns, etc., according to wire material and stator specifications to avoid equipment overload or winding defects caused by improper parameters.
Real-time monitoring: Monitor equipment operation status through HMI or host computer software; immediately stop and inspect if any abnormality is detected.
3. **Personal Protective Equipment:** Protective equipment: Operators are required to wear protective glasses, cut-resistant gloves, dust masks, etc., to prevent wire splashes, dust inhalation, or mechanical injury.
Safety signs: Post warning signs in hazardous areas of the equipment (such as rotating parts and high-voltage areas) to remind operators to pay attention to safety.
IV. **Strengthening Maintenance and Upkeep:**
1. **Daily Cleaning and Lubrication:** Clean the winding ends, wire laying mechanism, molds, etc., daily to remove wire ends, oil, and dust, preventing impurities from entering moving parts and causing wear.
1. Lubrication and Maintenance: Regularly apply lubricating oil or grease to moving parts such as guide rails, lead screws, and bearings to reduce friction and extend service life.
2. Regular Inspection and Replacement of Wear Parts
Wear Parts List: Establish a wear parts ledger (e.g., belts, bearings, carbon brushes, molds), record replacement cycles, and prepare spare parts in advance.
Preventive Maintenance: Develop maintenance plans based on equipment operating time or output, and replace worn parts in advance to avoid sudden failures.
3. Spare Parts Management and Inventory
Key Spare Parts Reserves: Reserve commonly used spare parts (e.g., servo motors, drivers, sensors) to ensure quick replacement in case of failure and reduce downtime.
Spare Parts Quality Verification: Before replacing spare parts, verify that their model and specifications are consistent with the original parts to avoid new failures caused by incompatible spare parts.
V. Examples of Common Small Methods
1. Wire Breakage Prevention Techniques:
Install a tension buffer device (e.g., spring or cylinder) at the winding end to absorb sudden changes in wire tension and prevent wire breakage.
1. **Wire Diameter Detection Sensor:** The machine automatically stops when the wire diameter is abnormal, preventing wire breakage due to excessively thin wire.
2. **Anti-Jaw Jam Methods:**
Install guide wheels or brushes at the mold inlet to guide the wire smoothly into the slot, reducing the risk of jamming.
Optimize the wire routing algorithm to ensure tight and non-overlapping wire arrangement, preventing jamming due to messy routing.
3. **Emergency Stop Optimization:**
Install multiple emergency stop buttons on the equipment control panel and in hazardous areas to ensure operators can quickly stop the machine in emergencies.
Regularly test the emergency stop function to ensure its response time meets safety standards (e.g., ≤0.5 seconds).
4. **Dustproof and Heat Dissipation Design:**
Install cooling fans or air conditioners in the control cabinet to maintain the operating temperature of electrical components within a reasonable range (e.g., ≤50℃).
Install dust filters at the equipment air inlets and clean dust regularly to prevent overheating and damage to electrical components due to poor heat dissipation.
