1、 Maintenance purpose and industry background

1.1 Core maintenance objectives
The precision optical components and high-precision transmission system of the visual labeling machine are highly sensitive to the operating environment. Research has shown that regular maintenance can reduce equipment failure rates by over 60%, achieved through standardized maintenance

• Ensure the stability of ± 0.1mm level visual positioning accuracy
• Extend the lifespan of key components (increase the lifespan of screws/guides by 3-5 years)
• Reduce downtime losses (increase production line efficiency by 15% -20%)

1.2 Industry application pain points
According to the 2024 packaging equipment maintenance data, 75% of visual labeling machine failures are caused by insufficient lubrication or dust intrusion, including:

• 32% of misjudgments are caused by visual lens contamination

• The proportion of stuck screw drive system is 41%
  

2、 Systematic Maintenance Implementation Plan

2.1 Level 3 Maintenance Framework

2.2 Detailed explanation of key maintenance steps

Step 1: Optical System Maintenance

• Lens cleaningUse a specialized dust-free cloth with isopropanol (concentration ≥ 99%) for spiral wiping to avoid fiber residue
• Light source calibrationTest the uniformity of the light source through a grayscale card, and the brightness deviation should be less than 5%

Step 2: Maintenance of the Transmission System

• Screw lubricationLithium based grease (NLGI grade 2) is used, with a grease injection volume of 3-5g per time
• Guide rail cleaningAfter blowing with a cleaning gun, apply Molykote EM-30L long-lasting lubricant

Step 3: Electrical system protection

• Servo motor cooling fins are subjected to reverse dust removal with compressed air every month (pressure ≤ 0.3MPa)
• The encoder interface is treated with CRC 2-26 anti-oxidation spray every quarter

3、 Standardized homework tools and recording system

3.2 Maintenance Record Form (Example)

4、 Typical Enterprise Application Cases

A certain food packaging company has implemented this maintenance plan:

1. Decreased failure rateAnnual maintenance frequency has decreased from 28 to 9 times
2. Consumables savingsThe label loss rate has decreased from 1.2% to 0.4%
3. Certification EnhancementCertified by ISO 15378 for pharmaceutical packaging equipment

5、 Intelligent upgrade direction

5.1 Predictive Maintenance System
Install vibration sensor IoT module to achieve:

• Warning of screw wear 3 weeks in advance
• Intelligent reminder of lubrication cycle (error<8 hours)

5.2 AR assisted maintenance
Using Hololens glasses to display 3D disassembly and assembly instructions, reducing the training cycle for new employees by 70%

Conclusion
A scientific maintenance plan is the core measure to ensure the efficient operation of visual labeling machines. Enterprises should establish a complete management system that includes personnel training, tool allocation, and data traceability. With the popularization of Industry 4.0 technology, it is recommended to gradually introduce digital twin technology to achieve full lifecycle health management of equipment.
