Annual maintenance for die bonders should be carried out in a structured sequence covering mechanical, electrical, optical, pneumatic, software, and performance systems. The following steps provide a practical reference for comprehensive inspection and servicing.
1. Appearance and Mechanical Structure
Clean the machine body using a neutral cleaning agent and a soft cloth. Avoid letting liquid seep into internal components.
Check all screws and nuts for looseness. Tighten as needed, and adjust or replace worn belts and chains. For deformed spacers, brackets, or non-standard mounting parts, Hansheng Automation can provide small-batch replacement machining according to the equipment manual specifications.
Lubricate ball screws, guide rails, and bearings with the lubricant type specified by the original manufacturer.
2. Electrical System
Inspect wiring inside the control cabinet for aging, cracking, or damage. Replace any faulty cables.
Test contactors, relays, and other electrical components. Replace those that no longer function reliably.
Clean dust from cooling fans and heat sinks to maintain proper heat dissipation.
3. Optical System
Wipe optical lenses with lint-free cloth and professional cleaning solution.
Run the equipment calibration program to confirm imaging accuracy.
Check illumination modules and adjust or replace any with uneven brightness.
4. Pneumatic System
Inspect air tubing and replace cracked or aged lines to ensure no leakage.
Remove and clean air filters to eliminate moisture and impurities.
Use a pressure gauge to verify and adjust air pressure to the standard value specified in the equipment manual.
5. Software System
Back up production parameters and programs to external storage.
Install the latest firmware version released by the manufacturer.
Verify all software functions to confirm normal operation.
6. Performance Testing
Use standard samples to check die placement deviation, which should be within ±0.01 mm.
Run continuous production to verify UPH meets the required level.
Conduct a four-hour stability test while monitoring vibration and noise.
Key parameters such as placement accuracy and air pressure should follow the equipment manual. Lubricant and replacement part specifications must be consistent with original factory requirements to ensure reliable long-term operation.
