THE CHALLENGE
Paint Robot Programming Challenges
Inconsistent Quality
Paint thickness and coverage varied between parts and between shifts. Some areas had excess paint buildup; others had insufficient coverage.
Robot Path Issues
The paint robots' programmed paths weren't optimized for the part geometries. This caused uneven application and wasted paint material.
Cycle Time Pressure
Production demand was increasing, but the paint process couldn't run faster without quality issues. Something had to change.
Troubleshooting Delays
When quality issues occurred, identifying the root cause took too long. Was it the robot? The paint parameters? The PLC timing?
Commissioning Validation
New equipment had been installed but wasn't performing to specification. The commissioning needed validation before full production.
OUR SOLUTION
Our Paint Robot Solution
Robot Path Optimization
We analyzed and reprogrammed the paint robot paths.
- 3D analysis of part geometry and paint coverage
- Path point refinement for consistent distance-to-surface
- Speed optimization for uniform film thickness
- Overlap pattern adjustment to eliminate thick/thin areas
Paint Parameter Optimization
Working with the paint process team, we fine-tuned application parameters.
- Atomization pressure and fan width settings
- Flow rate calibration per zone
- Electrostatic charge optimization
- Flash time adjustments between coats
PLC Troubleshooting
We identified and resolved controls issues affecting quality.
- Timing sequences between robot and conveyor
- Sensor calibration for part detection
- Interlock logic that was causing unnecessary stops
- Communication issues between paint booth zones
Commissioning Validation
For newly installed equipment, we validated.
- Robot reach and path verification
- Safety system function testing
- Throughput capability confirmation
- Documentation and operator training
