Abstract: For the disadvantages of low efficiency and difficulty in quality control of the main drive assembly process in shield machines, a main drive assembly production line integrating efficient assembly and data transmission was developed. Based on the overall design scheme of the main drive assembly production line of shield machine, a research was conducted on key technologies such as automated cleaning of main drive parts, material automated transportation, automated assembly of components, real-time detection and storage of tightening information for fasteners, and intelligent scheduling systems. Highly integrated automated equipment replaced traditional manual assembly processes, improving the quality and efficiency of main drive assembly while achieving the management and traceability of assembly information, forming the core technology system of the main drive assembly production line. The designed main drive assembly production line of shield machine was successfully built and the actual process verification was completed, achieving the design effect. It has now been successfully applied to the assembly production of various main drive specifications, achieving significant economic benefits.
