SMxTROUGH project introduction
Flexible·High speed·Stable·Intensive·Unmanned

The robot flexible production line adopts TOYOTA’s unique mixed-line production mode for 4–6 car body side panels, with a production cycle of 48 seconds per piece. It independently completes the overall planning of the production line, as well as 3D simulation design and analysis, allowing users to intuitively understand the effectiveness of the plan at the design stage, thereby reducing the error rate and shortening the project cycle.The line uses Japan’s NACHI high-speed robot welding to ensure accurate and high-quality solder joints. Multi-station applications of AGVs transport parts in place, while 3D visual recognition automatically guides the robot to grasp the parts, realizing rapid and flexible production.During the entire welding process, automatic collection, feedback, and optimization of various parameter information are implemented.

This robotic flexible production line adopts Toyota’s mixed-model approach to produce 4–6 types of body side panels at a cycle time of 48 seconds per unit. Independently planned and simulated in 3D, the line enables early validation, reducing errors and shortening the project timeline. It incorporates NACHI welding robots for high-quality joints, AGVs for material handling, and robotic oil spraying that cut labor by 50% compared to manual brushing. By using NC tooling with quick-change fixtures and overhead-mounted robots, the line achieves mixed production for 7 models while reducing floor space by 30%. Virtual commissioning slashed debugging time by 70%, and Toyota’s proprietary control technology ensures Industry 4.0 compliance, delivering an annual output of 228,000 units.
