The rotor automatic line is the core production line in motor manufacturing, responsible for rotor assembly, processing and testing, and is widely used in new energy vehicles, industrial motors and home appliances. Daily maintenance is essential to ensure its efficient and stable operation and extend the life of the equipment. This article provides practical and systematic maintenance suggestions to help operators and companies keep the rotor automatic line in the best condition and reduce failure rates and operating costs.
The rotor automatic line involves high-precision equipment (such as CNC presses, laser welding machines and dynamic balancing testers), and any minor failure may lead to production interruptions or product quality degradation. Daily maintenance can not only prevent equipment wear and failure, but also improve production efficiency, extend equipment life (usually up to 10 years or more), and reduce maintenance costs. Statistics show that standardized maintenance can reduce equipment failure rates by 70% and save 20% of annual operating costs.
Perform a quick inspection before and after starting up and shutting down the machine every day to ensure that the equipment is in good condition:
Mechanical parts: Check whether the protective cover, conveyor belt and clamp are loose or worn, and confirm that there is no foreign matter stuck in the moving parts.
Electrical system: Check whether the cable connection is firm, observe whether there are abnormal alarms on the control panel, observe the indicator light and sensor status, and eliminate the hidden dangers of short circuit or leakage.
Lubrication: Add appropriate amount of lubricating oil to the servo motor, guide rail and bearing to reduce friction.
Cleaning: Remove metal chips, dust and oil stains on the workstation to prevent affecting the accuracy of the sensor or causing electrical failure.
Recommended time: Daily inspection takes about 15 minutes, and record abnormal conditions in the maintenance log.
Perform a comprehensive inspection once a week, focusing on key components:
Dynamic balancing machine: calibrate the rotor balancing accuracy (the error is controlled within 0.01g·mm), and check whether the clamping device is worn.
Laser welding equipment: Clean the laser head lens, check the water level and filter of the cooling system to prevent overheating.
Pressing equipment: Test the accuracy of the pressure sensor, adjust the hydraulic or pneumatic system, and ensure the stability of the pressing force.
Transmission system: Check the belt tension and roller wear, adjust the centering accuracy, and prevent the rotor from shifting.
Recommended time: Maintenance for about 1 hour per week, operated by professional technicians when necessary.
Perform in-depth maintenance once a month to extend the life of the equipment:
Electrical detection: Use a megohmmeter to test the insulation resistance (should be ≥10MΩ) and check whether the terminal is loose.
Lubrication update: Replace the aging lubricant, and it is recommended to use high-temperature resistant synthetic lubricant (such as ISO VG 68).
Software update: Check the PLC control system and HMI (human-machine interface) software version, update to the latest firmware, and fix potential vulnerabilities.
Environmental control: Check the ventilation and temperature control system of the production line to ensure that the working environment temperature (20-30℃) and humidity (40-60%) are appropriate to prevent overheating or corrosion of the equipment.
Recommended time: Maintenance for about 4 hours per month, and shutdown operation is required.
Perform a comprehensive overhaul every quarter, and optimize the maintenance plan in combination with data analysis:
Replacement of key components: Replace severely worn seals, bearings or belts to prevent sudden failures.
Performance testing: Perform full-load operation tests on the entire production line, record production beats, yield rate and energy consumption data, and evaluate equipment efficiency.
Digital twin analysis: Use digital twin technology to analyze historical operation data, predict component life, and develop preventive replacement plans.
Maintenance records: Update maintenance files, record the findings and treatment measures of each overhaul, and provide reference for subsequent maintenance.
Recommended time: Quarterly maintenance is about 8 hours, and professional teams are required.
A new energy vehicle motor factory has significantly improved the performance of the rotor automatic line by implementing a systematic maintenance strategy. Daily inspections discovered and repaired the problem of slight conveyor belt offset, avoiding rotor misalignment; monthly maintenance optimized the cooling system of the laser welding machine and extended the life of the laser by 20%; quarterly data analysis predicted the timing of bearing replacement and reduced downtime losses. Finally, the annual failure rate of the production line dropped from 5% to 1%, and the annual maintenance cost was saved by about 250,000 yuan.
Safety first: disconnect the power supply before maintenance, hang a "maintenance" warning sign, and operators need to wear protective gloves and glasses.
Professional training: Maintenance personnel need to receive no less than 20 hours of equipment maintenance training and be familiar with the equipment structure and safety regulations.
Spare parts management: reserve common spare parts (such as bearings and seals) to ensure that they can be quickly replaced in case of failure.
Environmental cleanliness: keep the production line dust-free and oil-free, and clean the ventilation filter regularly.
