Summer brings higher temperatures, increased humidity, and more airborne dust, all of which can affect machine performance and production stability. Electrical systems, pneumatic components, glue systems, sensors, and mechanical transmission components are particularly susceptible to seasonal environmental changes.
To minimize unplanned downtime and maintain efficient production, regular inspections and preventive maintenance are highly recommended.
1. Keep Electrical Cabinets Properly Ventilated
High ambient temperatures can increase the internal temperature of electrical cabinets, potentially affecting PLCs, servo drives, inverters, relays, and other critical electrical components.
Recommended Actions:
Clean cabinet filters, cooling fans, and ventilation openings regularly.
Verify that all cooling fans are operating properly.
Keep cabinet doors closed to prevent dust and moisture from entering.
Consider additional cooling solutions, such as air conditioning or industrial cooling systems, in high-temperature workshops.
Investigate recurring drive alarms promptly and check for overheating or excessive load conditions.
2. Monitor Compressed Air Quality and Pneumatic Components
Hot and humid weather can increase moisture levels in compressed air systems, affecting the performance of cylinders, solenoid valves, vacuum generators, and pneumatic fittings.
Recommended Actions:
Inspect the air filter and water separator daily, and drain accumulated condensate regularly.
Ensure air pressure remains within the machine’s specified operating range.
Inspect air hoses and fittings for leaks or signs of aging.
Check cylinders for smooth operation and watch for delays, sticking, or unusual noise.
If vacuum performance becomes unstable, inspect suction cups, vacuum lines, and filters for blockages or wear.
3. Maintain the Glue System Properly
Temperature fluctuations during summer can affect glue viscosity and flow performance. Without proper maintenance, issues such as glue clogging, stringing, overflow, or inconsistent glue application may occur.
Recommended Actions:
Store glue in a cool, dry, and sealed environment.
Avoid mixing new glue with old glue.
Check the glue level and condition before starting production each day.
Clean glue guns, nozzles, filters, hoses, and glue tanks regularly.
Follow the recommended cleaning or preservation procedures during extended machine downtime.
Replace the glue immediately if it shows signs of contamination, thickening, or deterioration.
4. Keep Sensors and Vision Systems Clean
Dust, paper fibers, and glue mist can accumulate on photoelectric sensors, fiber-optic sensors, proximity switches, cameras, and lighting systems, leading to detection errors or positioning issues.
Recommended Actions:
Use clean, dry compressed air to remove dust from sensor surfaces daily.
Wipe camera lenses and light sources with a lint-free cloth.
Verify that sensors remain securely mounted and properly aligned.
When false alarms occur, check for dust, paper debris, or glue contamination around inspection points.
For vision systems, inspect lighting conditions, lens cleanliness, and product positioning if recognition accuracy decreases.
5. Inspect Mechanical Transmission Components
Belts, chains, bearings, gears, guide rails, and other moving components are subject to increased wear and lubrication challenges during prolonged operation in high-temperature environments.
Recommended Actions:
Inspect conveyor belts for tracking issues, looseness, wear, or glue buildup.
Check the lubrication condition of chains, gears, guide rails, and lead screws.
Remove paper scraps and glue residue from conveyor paths, around molds, and guide channels.
Verify that mounting bolts and fasteners remain secure.
Investigate unusual noise, vibration, or increased running resistance immediately.
6. Verify Robot and Safety System Performance
For machines equipped with robots, robotic arms, or automatic packing systems, special attention should be given to grippers, suction cups, cables, and safety fences during continuous summer operation.
Recommended Actions:
Inspect robotic grippers, suction cups, and vacuum lines regularly.
Ensure the robot operating area remains free of obstructions.
Verify the functionality of safety doors, emergency stop buttons, safety light curtains, and interlock systems.
Never enter the robot operating zone while the machine is running automatically.
Before restarting after an alarm, confirm that no collision, overload, or vacuum-related issue has occurred.
Conclusion
Effective summer machine maintenance focuses on five key principles: cooling, moisture control, cleanliness, lubrication, and prevention.
By implementing routine inspections and preventive maintenance practices, manufacturers can significantly reduce machine failures, improve production reliability, and maintain consistent operational efficiency throughout the summer season.
If your machines experience frequent alarms, positioning issues, glue application problems, or mechanical instability during summer operation, professional inspection and maintenance are recommended to prevent further downtime and ensure optimal performance.
