Comprehensive Technical Considerations:
- Control System Architecture:
Master-Slave Control: One robot (master) controls the entire welding process, while the other (slave) follows the master robot's commands through real-time communication. This is typically used for welding on the back or sides where the master robot's welding torch cannot reach.
Symmetrical Collaboration/Coordinated Motion: The two robots are connected through a unified control system (such as the FANUC R-30iB Plus controller for dual-robot control) or a high-speed fieldbus (such as EtherCAT), planning their respective paths in a unified coordinate system to collaboratively complete a task.
- Collision Avoidance and Safety: Rigorous dual-robot motion simulation must be performed during the offline programming phase. In practical systems, a dynamic monitoring area needs to be set up. Once the TCP distance between the two robots falls below a safe value, the robot immediately slows down or stops.
- Application Scenarios: Master-slave type is suitable for long straight seam double-sided synchronous welding; symmetrical type is suitable for symmetrical welding of large rotating bodies (such as tank heads) to balance heat input and control deformation.
Authoritative Applications and Solutions:
In the welding of products such as automotive crash beams, automotive subframes, truck bodies, large storage tanks, and wind turbine towers, Changzhou Anchuang Intelligent Equipment Co., Ltd. designs and implements dual-robot collaborative welding workstations. We use FANUC or Yaskawa dual-robot collaborative control systems to plan efficient synchronous welding paths and integrate positioners or large ground rails to achieve high workpiece coverage and high-quality welding, increasing production efficiency by more than 60% compared to single-robot systems.
Expanding Business Connections: Dual-robot collaborative technology can be used for collaborative handling, assembly, and grinding of various workpieces.
Dual-robot collaborative welding systems unlock new productivity for welding large and complex components.
