Product Description
To achieve synchronization, the Press PLC and the Robot Controller must share data with sub-millisecond latency. We utilize high-speed industrial Ethernet protocols to transmit the Absolute Encoder position of the press crankshaft directly to the robot's motion engine.
- Profinet IRT (Isochronous Real-Time): Ensuring jitter-free data exchange.
- EtherCAT: Providing the fastest "on-the-fly" processing for high-SPM lines.
- EtherNet/IP with CIP Sync: Standard for many North American automotive Tier-1 plants.
Instead of waiting for a "Press at Top" digital signal, the robot is programmed as a Slave Axis to the press's Master Axis.
- Dynamic Entry: As the press slide passes 270° (ascending), the robot calculates its acceleration curve to reach the pick point exactly when the die is clear.
- Continuous Path Tracking: If the press speed fluctuates (e.g., due to motor load or operator adjustment), the robot automatically scales its velocity to match, maintaining a constant safety gap.
Performance benchmarks for synchronized stamping.
| Feature | Specification | Operational Impact |
|---|---|---|
| Sync Latency | < 2 ms | Allows for tighter "overlap" between press and robot |
| Encoder Resolution | 13-bit to 17-bit Absolute | High-fidelity tracking of the press slide position |
| SPM Capability | 12 - 18 Strokes Per Minute | Typical for 6-axis robotic tandem lines |
| Interference Window | Configurable (1° increments) | Maximum safety with minimum "dead time" |
| Safety Protocol | PROFIsafe / CIP Safety | Integrated Estop and Speed Monitoring |
| Motion Profile | S-Curve / Jerk-Limited | Protects robot gears and prevents part slippage |
- Tandem Line "Overlap" Control: Coordinating 5+ robots across a line where the exit move of Robot A must synchronize with the entry move of Robot B into the same press.
- Servo-Press Integration: Leveraging the variable speed of servo presses to allow the robot more time for complex part orientation without stopping the crank.
- On-the-Fly Centering: Using vision data to adjust the robot's "Place" coordinates while it is already in motion toward the press, ensuring ±0.5 mm accuracy.
