Aiming at the problems of low production efficiency and unstable welding quality of prefabricated steel mesh for traditional railway bridge pylon,the idea of replacing traditional manual production with industrial robot was proposed,and a steel mesh production line based on robot cluster manufacturing was designed.The traditional production process was analyzed,and the overall design scheme of replacing the whole process with industrial robot was put forward from the characteristics of each process.A fully automated production line and production process of steel mesh based on robot were designed by combining with robot operation assisted mechanical structure and industrial vision system.Finally,the feasibility and practicability of the production line scheme were verified by test and engineering application.The results show that the production efficiency of steel mesh based on robot cluster manufacturing is higher,the welding quality is more stable, the labor intensity and labor cost are reduced,and the expected design effect is achieved.
