Description

Technical Field

[0001] The present invention relates to the technical field of aero-engine assembly, in particular to an intelligent assembly system for piston-type aero-engines. Background Art

[0002] The manufacturing and assembly of aircraft engines requires extremely high precision. Aircraft engines are composed of numerous components, each of which must be precisely coordinated, placing even higher demands on the quality of their assembly. Numerous factors influence the assembly process, and ensuring quality requires proactive control of all aspects of the assembly process and the factors influencing it. Targeted management and control measures are also needed to ensure this quality. Pre-assembly prevention, in-process quality supervision, key point management, and a comprehensive inspection mechanism can be used to maximize quality assurance.

[0003] As a manufacturing execution system for the assembly line, it can monitor, track and store the aircraft engine assembly process, making the engine assembly process controllable, traceable and traceable.

[0004] The Manufacturing Execution System provides operators and users with traceability and query capabilities for product assembly process quality and material data, as well as visual guidance for the assembly process. A real-time, integrated production management platform is established. Through an integrated database, production planning tasks are promptly issued, work-in-progress is tracked, and interfaces with production line automation equipment are integrated to monitor production status in real time, collect key data, and serve in-plant manufacturing. This production line data is also aggregated into enterprise resource planning systems for unified management, encompassing overall factory quality, processes, and production. This production line is a typical assembly line, but unlike traditional assembly lines, its individual workstations are relatively independent, allowing for flexible adjustment of the assembly sequence. Therefore, this assembly line is a typical multi-batch, small-batch discrete production line.

[0005] The functional modules of this manufacturing execution system are divided into major categories such as planning management, quality data, real-time data, statistical analysis, equipment management, system settings, and system management. Summary of the Invention

The enterprise resource planning system server, the manual document input terminal, the manufacturing execution system server and the remote server perform two-way information exchange, the manufacturing execution system server and the warehouse management computer input control signals and send them to the workstation equipment, the industrial Ethernet and the AGV scheduling system through the Ethernet, the large display screen server receives the signal and displays it on the large display screen, and the AGV scheduling system receives the signal and sends it to the wireless network, the barcode scanner and the AGV port.

[0008] Preferably, the output end of the industrial Ethernet can be expanded to multiple modules.

S7: The on-line workstation is equipped with a laser marking machine, which automatically engraves the serial number of the model scheduled for production on the engine after the AGV is in place. Real-time quality data is printed on the work card through a printer for easy viewing.

[0011] The benefit of the present invention is that it can trace the quality of the entire line at the finished product end, quickly change models, adapt to the small batch and multi-variety needs of general aviation engines, reduce dependence on senior technicians, and form a standardized knowledge base.
