The primary stripper foil device is one of the most critical devices of The China Spallation Neutron Source Project Phase-II (CSNS-II), which requires regular foil replacement maintenance to ensure its stable operation. To mitigate the potential hazards posed to workers by prolonged exposure to high levels of radiation, a maintenance robotic system has been developed to perform repetitive and precise foil changing task. The proposed framework encompasses various aspects of the robotic system, including hardware structure, target detection, manipulator kinematics design, and system construction. The correctness and efficiency of the sys-tem are demonstrated through simulations carried out using ROS Moveit! and GAZEBO.

	This paper developed a dedicated disassembly and assembly handcart for CSNS magnetic alloy cavity vacuum chamber. The optimal supporting section structure was determined by the use of ANSYS to analyze the strength of different sections. The stress situation of the handcart was improved by adding an extension rod at the end of the handcart. The installation position of the handcart was determined by the center position of the associated equipment. The development of the disassembly and assembly handcart structure was completed through structural optimization, disassembly and assembly process analysis, and positioning scheme design. The development of a handcart can improve the positioning accuracy of the vacuum chamber and prevent damage to the vacuum chamber during disassembly and assembly process.

	Funding: National Natural Science Foundation of China, 11975253 Stripper foil is a key equipment for converting negative hydrogen ions into protons in the RCS injection zone of CSNS. The structure of the CSNS primary stripper foil adopts a rotating steel strip structure, and the replacement time of the foil is long, requiring operators to carry out maintenance work in close proximity for a long time. The energy of CSNS-II injection beam has significantly increased from 80MeV to 300MeV, and the radiation dose in the injection area will also increase, making it impossible to maintain the equipment in close proximity for a long time. Therefore, it is necessary to redesign the primary stripper foil. This article will analyze the stripper efficiency and beam injection thermodynamics of CSNS-II stripper foil, carry out automatic foil store replacement structure design, motion analysis, and prototype testing, and envision remote maintenance solutions to achieve maintenance and repair of the stripper foil with minimal human intervention.
