Objective The assembly line units for high-speed EMU(electric multiple unit) face issues such as cumbersome registration and difficult traceability in traditional tool management processes. To meet the requirements of "high precision, high safety, high efficiency, and high compliance", and support the lean production and smart manufacturing upgrade, an application analysis of intelligent tool cabinets for rail transit equipment manufacturing industry is required in terms of providing tool management path optimization.

Method The working principles and functional characteristics of intelligent tool cabinet are analyzed. Taking the assembly production line and the bogie assembly line of CRRC Changchun National Railway Business Department as research objects, field investigation and case analysis are utilized to discuss the adaptability of intelligent tool cabinet functions, such as RFID (radio-frequency identification) technology and face recognition to assembly process needs. The causes for unfamiliarity with operation and system docking delay issues are analyzed. By summarizing problems and challenges in the application of intelligent tool cabinets, optimization strategies including training enhancement and interface optimization are proposed.

Result & Conclusion  The application of intelligent tool cabinets has significantly enhanced management efficiency at production sites, achieving a 30% to 50% reduction in tool issuance and return time, a great improvement in inventory accuracy, and a marked decline in tool loss rate. The intelligent tool cabinet realizes the transformation of tool management from passive to active. Its functions, such as docking with the Rongshu Platform, provide a practical paradigm for the digital upgrade of manufacturing production line units.
