Abstract: In order to solve the problems in the series typesetting of photovoltaic cells, such as the position deviation of photovoltaic cells on the conveyor belt after series welding, the position of photovoltaic cells after placing on the substrate needs to be fine-tuned, the high failure rate of traditional truss typesetting machine, the difficulty of debugging, and the occupation of production time. This paper proposes the solution of robot replacing truss typesetting machine. RobotStudio simulation software is used to design a simulation workstation. In the workstation, the positioning camera positioned the photovoltaic cell string on the conveyor belt, and guided the IRB1300 robot to grab the battery string and put it on the substrate; The correction camera locates the battery on the substrate, and the IRB920 robot corrects the battery. In order to verify the robot's grasp and release of batteries with position deviation, IS2000-230 is used to locate photovoltaic cells and update the position of photovoltaic cells in the simulation workstation in real time. At the same time, the upper computer system based on C# is developed to realize the monitoring and real-time adjustment of the robot system. The scheme realizes the typesetting and correcting of battery string by the industrial robot with high reliability, which can reduce the overall failure rate and improve the reliability of the system.
