Cantilever-Type Dual-Robot Intelligent Workstation

This intelligent welding solution for ship sub-assembly—built upon an advanced, intelligent control architecture—utilizes a "1 master, 4 slave" multi-robot collaborative control system. By integrating digital reverse-assembly technology for workpieces, the system enables dynamic task allocation among multiple robots and automatic generation of welding paths, significantly reducing the need for manual teaching. The solution supports a full range of weld types—including horizontal-vertical fillet welds, vertical fillet welds, wrap-around fillet welds, and arc welds—fully meeting the welding production requirements for primary, planar, and complex, irregularly shaped sub-assembly structural components.

We offer three production line layout configurations—a four-machine conveyor line, a lateral production line, and an AB-crossover production line—which can be flexibly selected based on available factory space and production capacity targets. The core unit is an intelligent workstation featuring dual cantilevered robots; its cantilevered frame design ensures an extensive operational reach and fluid robotic movement, making it well-suited for processing sub-assembly components such as hull stiffeners, T-profiles, and brackets.

[Operational Scenario] Once workpieces are hoisted into position within the workshop, a 3D vision system rapidly scans and identifies their actual assembly state, subsequently reconstructing a digital model of the components. The master control system automatically breaks down welding tasks, coordinating dual robots to perform autonomous path planning and execute simultaneous multi-seam welding, all while dynamically avoiding collisions. Welding operations are seamlessly integrated with loading and unloading processes; utilizing an A/B station configuration, the system allows for welding on one side while workpieces are positioned on the other, effectively eliminating equipment idle time. The workstation accommodates assembly deviations in components supplied by the shipyard, ensuring stable weld formation. This solution significantly reduces manual labor intensity, enhances the efficiency and consistency of sub-assembly welding, and facilitates the digital transformation of pre-assembly processes for shipbuilding segments.
