Description

Technical Field

[0001] This invention relates to the field of automated production line technology, specifically to an automated flexible safety production system for the final assembly of fire-prone aircraft and its execution method. Background Technology

[0002] As the backbone of national defense and military defensive weaponry, aircraft play an irreplaceable and vital role in safeguarding national security and territorial integrity. Traditional fire-prone aircraft assembly processes rely heavily on manual labor, employing a "one-stop assembly" model where the entire assembly process is completed at a single workstation or a small number of workstations. Storage of fire-prone aircraft assembly equipment typically involves laying items flat on warehouse or temporary storage areas, resulting in large footprints, low retrieval efficiency, and a high risk of errors. Logistics for fire-prone aircraft assembly utilizes manual hoisting and personnel transfer via transport vehicles, leading to a large number of personnel required for transfers, low efficiency, and significant safety hazards due to the manual hoisting and transfer processes. Production scheduling for fire-prone aircraft assembly employs a manual scheduling team centered around workshop dispatchers and supported by shift leaders and team leaders. Scheduling information must pass through multiple levels from dispatchers to operators, resulting in low efficiency and susceptibility to information distortion. Safety management for fire-prone aircraft assembly relies on manual registration, with the equivalent of pyrotechnic materials and the number of personnel in the factory depending on paper ledgers and manual counting, leading to poor timeliness and accuracy.

[0003] Therefore, in order to meet the requirements of safe production, intensive warehousing, automated logistics, intelligent scheduling, high efficiency, and high reliability in the final assembly production of fire-related aircraft, this invention provides an automated flexible safety production system for the final assembly of fire-related aircraft and its execution method, so as to achieve a high degree of automation, high flexibility, and high safety in the final assembly production of fire-related aircraft.

The system includes an automated adhesive application subsystem, a foam bonding subsystem, a safety detection system, and a control system. The control system is connected to the automated adhesive application subsystem, the foam bonding subsystem, and the safety monitoring system.

[0013] According to the present invention, an automated flexible safety production system for the final assembly of fire-prone aircraft is provided, which performs the following steps using the aforementioned automated flexible safety production system for the final assembly of fire-prone aircraft: Step S1: Receive production road cards from the upstream system and generate a workshop production plan; Step S2: Bind the workshop production plan to the process program, execute production scheduling, and calculate and generate production work orders; Step S3: Execute the production system self-inspection procedure. After passing the test, start production on the designated assembly and testing sub-line.

Step S3.6: Check whether the production line environment meets the requirements of the final assembly production process; Step S3.7: Check whether the number of production line personnel is higher than the minimum requirement in the final assembly production process.

[0016] Preferably, in step S4, the steps for executing the logistics task include: Step S4.1: Based on the logistics task information, the logistics service generates outbound tasks for fire-related products from a flat warehouse or for non-fire-related products from a three-dimensional warehouse, as well as empty AGV transfer tasks, AGV material transfer tasks, AGV material transport tasks, material transfer tasks for logistics conveyor lines or flexible docking devices in cargo compartments or for aircraft loading devices, and begins to execute outbound tasks for fire-related products from a flat warehouse or for non-fire-related products from a three-dimensional warehouse, and empty AGV transfer tasks. Step S4.2: The equipment control service schedules materials to be shipped from the designated storage location of the fire-related product planar storage warehouse according to the outbound task; it also schedules materials to be shipped from the designated storage location of the non-fire-related product automated storage warehouse according to the outbound task; and the logistics module schedules AGVs to move to each outbound port according to the AGV empty vehicle transfer task.

[0025] The aforementioned execution method for the production system, such as Figures 1-4 As shown, it includes the following steps: Step S1: Receive production road cards from the upstream system and generate a workshop production plan; Step S2: Bind the workshop production plan to the process program, execute production scheduling, and calculate and generate production work orders; Step S3: Execute the production system self-test procedure. If it passes, automatically designate an available assembly and testing subline to start production. Step S4: Automatically calculate and generate logistics tasks, and execute the logistics tasks; Step S5: Automatically calculate and generate production process tasks, personnel positioning tasks, and equipment control tasks; Step S6: The operator starts the operation; Step S7: After the required materials for the process are delivered, the relevant operations can be performed automatically or manually according to the process step settings. Step S8: After completing all steps, click "Complete" to automatically schedule the equipment to transfer the product to the next workstation; Step S9: After all process tasks are completed, automatically calculate and generate logistics tasks, and execute them; Step S10: Work order completed.

The number of personnel in each area of ​​the production system is obtained from the intelligent monitoring unit of production line personnel, the total number of personnel is counted, and it is determined whether the production system is overstaffed. Based on the number of personnel in each area of ​​the production system, and in conjunction with the tasks being performed by the assembly auxiliary robots and gantry handling systems, it is determined whether there are any potential personal safety hazards to the personnel in the production system. The concentration of flammable and explosive gases and the particle size index at each detection point of the production system are obtained from the plant environmental monitoring unit to determine whether there is a risk of combustion and explosion in the production system.
