Description

Technical Field

[0001] This invention relates to the field of automated production line technology, and more specifically, to an automated production material flow system and method for aerospace product assembly. Background Technology

[0002] As a backbone of the defense industry, aerospace products play an irreplaceable role in safeguarding national security and territorial integrity. Traditional aerospace product assembly is primarily manual, employing a "one-stop assembly" production model. This means the assembly process is completed almost entirely at a single workstation or a very small number of workstations, with virtually no concept of a production line. Furthermore, based on this "one-stop assembly" model, the factory layout is solely focused on achieving production goals, leading to numerous problems such as shared personnel and material flows, long distances between workstations, and inefficient logistics.

[0003] With the advancement of my country's military system reform, the PLA's air defense weaponry and equipment have entered a period of rapid adjustment and development, and preliminary explorations have begun in the construction of aerospace product assembly lines. However, as research on production line construction is still in its initial stage, there is relatively little available literature for reference.

[0004] A search revealed that patent document CN107010468A discloses a layout structure for a cable factory production line, relating to the field of equipment layout in wire and cable factories. This layout involves two cable production lines, but these two lines are independent and do not interfere with each other; furthermore, the aforementioned layout only addresses operator convenience and aesthetics. In contrast, the layout provided by this patent combines independent sections with shared areas between the two production lines, saving both space and equipment resources.

[0005] A search revealed that patent document CN110893547B discloses a layout method for a civil technology composite material vertical tail assembly production line, relating to the field of aircraft assembly. This patent addresses the issues of large floor space and high equipment investment associated with single production lines through a dual-ring production line layout; while this invention patent achieves resource savings in terms of space and equipment through a "two production lines + shared area" approach.

[0006] A search revealed that patent document CN114371670B discloses a material handling method for a digital production line for cabin components, relating to the field of industrial automation technology. This method primarily addresses material handling during automated cabin component processing, solving the problem of continuous material handling in small-batch production, which relies heavily on hoisting / handling. In contrast, this invention focuses on material handling during the final assembly of aerospace products, employing a "rolling and moving" method with "zero hoisting" for over 90% of the material handling, significantly reducing the risks associated with material transfer. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automated production material flow system and method for aerospace product assembly.

[0008] An automated production material flow system for aerospace product assembly, provided by the present invention, includes: Centralized loading platform: Located at the entrance of the factory, all materials to be assembled are sorted through the centralized loading platform and stored in the warehouse for manual clamping and scanning before loading into the compartment. Positioning module: Located on the centralized loading platform, used to assist in the rapid positioning of compartments and brackets; Fire-prone flat storage: Located in the middle of the factory building, used for storing fire-prone materials to be assembled; Non-fire-prone automated warehouse: Located in the middle of the factory building, used for storing electronic compartment sections and material boxes of materials to be assembled; Intelligent tool library: located near a non-fire-related automated warehouse, used for storing tools and fixtures; Temporary buffer station: located near the factory exit area, used for finished product buffering; AGVs are used for material transfer between workstations; they act as mobile modules connecting centralized loading platforms, fire-prone flat warehouses, non-fire-prone automated warehouses, and workstations. Gantry robot: Located at the cannonball loading platform, used for loading the entire cannonball vertically; Ground-rail robot: It is distributed alongside the cartridge loading platform and aerospace product assembly platform, and is used for loading and unloading of directly attached parts on the cartridge loading platform and aerospace product assembly platform; Central control module: Used for material flow control. All equipment systems work together to complete the operation of the production line under the control of the central control module.

[0009] Preferably, the automated production line layout for an automated production material flow system for aerospace product assembly includes an assembly and testing sub-line, a centralized material loading platform, a distributed material storage area, a testing area, and a logistics area. The assembly and testing sub-lines are located on both sides of the factory building and are arranged in a straight line. They include a full ammunition assembly area, a cartridge loading platform, a testing area, and an exit area. The centralized feeding platform, distributed material storage area, and testing area are public areas, arranged in a straight line, located in the middle of the factory building, and together with the assembly and testing sub-line, they form two aerospace product assembly lines; the overall layout presents a W-shape or a co-linear double U-shape.

[0010] The distributed material storage area is located in the middle of the factory building and includes a fire-prone flat warehouse, a non-fire-prone three-dimensional warehouse, an intelligent tool library, and temporary cache workstations. The logistics area is a circular two-lane layout, and AGVs are used to realize the material flow of the assembly and testing sub-line, centralized feeding platform, centralized distributed material area and testing area. Preferably, the material conveying platform is located next to the ground-rail robot and is connected to the AGV for material transfer. The ground-rail robot grabs materials for use on the aerospace product assembly platform or the cartridge loading platform. Aerospace product assembly platforms are used for docking and assembling module-level products; The cartridge loading platform is used to load finished products produced by the aerospace product assembly platform into the cartridge body to form cartridge-grade products; The material conveying platform is arranged in parallel with the aerospace product assembly platform and the cartridge loading platform.

[0011] Preferably, the material conveying platform, aerospace product assembly platform, cartridge loading platform, AGV, testing platform, inspection platform, non-fire-related product automated warehouse, fire-related product flat warehouse, centralized loading platform, and temporary buffer station all contain roller mechanisms to ensure that the pallets can roll and move on them.

[0012] Preferably, the AGV is a shared resource of the assembly and testing sub-line, and meets the operational needs of two production lines under the scheduling of the central control module.

[0013] Preferably, in the non-fire-related automated warehouse: The material boxes are stored in a modular way: according to the work content at each workstation, the corresponding materials are placed in the same material box, and then the material boxes of the same aerospace product are stacked into a material box and stored in the same storage location.

[0014] Preferably, in the intelligent tool library: The intelligent tool library uses RFID technology to achieve unified management of tooling or equipment throughout the factory.

[0015] Preferably, the production line configuration, production line layout, and material flow method are the results of FlexSim simulation optimization. By building a FlexSim full-element simulation model, the boundaries and initial conditions such as production line capacity target, production cycle, production line balance, and personnel configuration are set. Then, the simulation results are fed back to the planning layer to drive the genetic algorithm parameter iteration until the solution simultaneously meets the three requirements of production line balance, capacity target, and constraint compliance, forming a closed-loop optimization.

[0016] According to the present invention, an automated production material flow method for aerospace product assembly is provided, which employs the aforementioned automated production material flow system for aerospace product assembly to perform the following: Step S1: Before the batch is loaded, the operator issues a batch non-fire-related product warehousing application through the central control terminal of the centralized loading platform at the entrance. The non-fire-related product automated warehouse will take out the compartment pallet and roll it to the compartment AGV. Step S2: Instruct the AGV of the compartment to transfer the pallet to the centralized loading platform and roll the pallet to the loading platform; Step S3: Install the cabin onto the pallet. During the installation process, the auxiliary positioning module quickly ensures that the cabin's position and attitude on the pallet meet the process requirements. Step S4: Scan the code to assemble the compartment and pallet, and the pallet containing the compartment is rolled and moved to the compartment AGV; Step S5: After placing the material box on the loading platform, scan the barcode to enter the warehouse, and the material box will roll and move to the compartment AGV; Step S6: Instruct the AGV of the compartment to transfer the pallet and material box containing the compartment to the non-fire-related product automated warehouse for storage. Step S7: Repeat steps S1 to S6 until the batch storage of non-fire-related products is completed. Step S8: One day before the start of the installation, the operator submits a batch of fire-related product warehousing application through the central control module terminal in the centralized material loading platform at the factory entrance. The fire-related product flat warehouse will take out the compartment or cylinder pallet and roll it to the full-explosive AGV. Step S9: Move the full-elastic AGV to transfer the pallet to the centralized loading platform and roll it to the loading platform; Step S10: Install the compartment or cylinder onto the pallet. During the installation process, the auxiliary positioning module enables the compartment or cylinder to quickly meet the process requirements in terms of placement position and orientation on the pallet. Step S11: Scan the code to assemble the compartment or cylinder with the pallet, and then the pallet containing the compartment or cylinder is rolled and moved to the full-explosive AGV; Step S12: Have the AGV transport the pallet containing the compartments or cylinders to the fire-related product storage area for storage. Step S13: Repeat steps S8 to S12 until the batch storage of fire-related products is completed; Step S14: On the day of installation, the operator issues the work plan for the day through the central control terminal or workstation terminal, and retrieves the tooling or equipment to be used that day from the tool or equipment intelligent storage repository. Step S15: The compartments, material boxes or cylinders of the fire-related product flat warehouse and the non-fire-related product automated warehouse are respectively taken out of the warehouse and rolled onto the AGV; Step S16: The AGV transports the above materials to the full ammunition assembly area and the cartridge loading platform respectively, and moves them to the corresponding platforms by rolling; namely, the material conveying platform on the material box, the full ammunition assembly platform on the compartment, and the cartridge loading platform on the cartridge. Step S17: During the assembly process of the entire missile on the assembly platform, the ground rail robot grabs the material box containing the missile's direct parts, standard parts, etc. and places it next to the assembly platform. Step S18: The compartment moves between workstations on the assembly platform by rolling. During the movement, it is assembled into a complete projectile. Then, the gantry handling robot grabs it and moves it to the cannonball loading platform for assembly. Empty pallets or material boxes that are left out during the assembly process are rolled onto AGVs and then transferred to the corresponding storage locations. Step S19: After the cartridge is loaded, it is moved to the AGV by rolling, then transferred to the test area and rolled to the test platform to complete the electrical performance related tests; Step S20: After the test, the cartridge is transferred to the AGV by rolling and then transported to the testing area; it is then moved to the inspection platform by rolling and for mechanical property testing. Step S21: After the inspection is completed, the cartridge rolls and moves to the AGV, and then is transported to the temporary buffer station in the export area to wait for the inter-factory logistics vehicle to transfer it to the outside of the finished product warehouse for storage; then the AGV transports the pallet to the storage location. Step S22: Repeat steps S14 to S21 until the daily production tasks are completed; Repeat steps S13 and S22 until the batch production task is completed.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. By sharing logistics routes, centralized material loading platforms, distributed material storage areas, and testing areas, two production lines can operate simultaneously, saving space resources while reducing investment in production line equipment.

[0018] 2. The logistics path adopts a circular double-lane layout, enabling multiple AGVs to shuttle back and forth between the two production lines. This not only ensures smooth logistics but also allows AGVs to be shared between the two production lines, thus greatly improving the utilization rate of AGVs.

[0019] 3. The centralized material loading platform, distributed material storage area, testing area and other public resources are arranged in the middle of the factory and distributed side by side with the two production lines, so that the distance of public resources to the two production lines is the same, which ensures the material delivery efficiency of the two production lines; at the same time, it is conducive to the balance of the cycle time of each workstation on the production line.

[0020] 4. All production line equipment adopts a "roller rail" structure, and more than 90% of material flow is carried out by "rolling movement". This greatly reduces the risk of product falling due to product hoisting, while making the production line more flexible. Attached Figure Description

This invention achieves automated operation of aerospace product assembly lines through the above-mentioned production line configuration, layout, and material flow methods. It has advantages such as low personnel participation, high production line efficiency, high material flow safety, compact layout, and high production line flexibility.

[0025] The material flow method includes the following steps: Step S1: Before the batch is loaded, the operator issues a batch non-fire-related product warehousing application through the central control terminal of the centralized loading platform at the entrance. The non-fire-related product automated warehouse will take out the compartment pallet and roll it to the compartment AGV.

[0026] Step S2: The AGV of the compartment transfers the pallet to the centralized loading platform and rolls the pallet to the loading platform.

[0027] Step S3: Install the cabin onto the pallet. During the installation process, the auxiliary positioning module enables the cabin to quickly meet the process requirements in terms of placement and attitude on the pallet.

[0028] Step S4: Manually scan the barcode to assemble the compartment and pallet, and then roll the pallet (including the compartment) to the compartment AGV.

[0029] Step S5: After placing the material box on the loading platform, scan the barcode to enter the warehouse. The material box will then roll and move to the AGV in the compartment.

[0030] Step S6: The AGV of the compartment transfers the pallet (including the compartment) and material box to the non-fire-related product automated warehouse for storage.

[0031] Step S7: Repeat steps S1 to S6 to complete the batch storage of non-fire-related products.

[0032] Step S8: The day before the start of assembly, the operator submits a batch (production quantity for the next day) application for fire-related products to be put into storage through the central control module terminal in the centralized material loading platform at the factory entrance. The fire-related product flat warehouse will take out the compartment / cylinder pallet and roll it to the full-explosive AGV.

[0033] Step S9: The full-elastic AGV transfers the pallet to the centralized loading platform and rolls it to the loading platform.

[0034] Step S10: Install the compartment / cylinder onto the pallet. During the installation process, the auxiliary positioning module enables the compartment / cylinder to quickly meet the process requirements in terms of placement position and orientation on the pallet.

[0035] Step S11: Manually scan the barcode to assemble the compartment / cylinder with the pallet, then the pallet (including the compartment / cylinder) is rolled and moved to the full-explosive AGV.

[0036] Step S12: The AGV transports the pallet (including the cabin / cylinder) to the fire-related product storage area for storage. Step S13: Repeat steps S8 to S12 to complete the batch storage of fire-related products.

[0037] Step S14: On the day of installation, the operator issues the work plan for the day through the central control terminal / workstation terminal and retrieves the tooling / tooling used that day from the tooling / tooling intelligent storage repository.

[0038] Step S15: The compartments / material boxes / cylinders of the fire-related product flat warehouse and the non-fire-related product automated warehouse are respectively taken out of the warehouse and rolled onto the AGV.

[0039] Step S16: The AGV transports the above materials to the full ammunition assembly area and the cartridge loading platform respectively, and moves them to the corresponding platforms by rolling; namely, the material conveying platform on the material box, the full ammunition assembly platform on the compartment, and the cartridge loading platform on the cartridge.

[0040] Step S17: During the assembly process of the entire missile on the assembly platform, the ground-rail robot grabs the material box containing the missile's direct components, standard parts, etc., and places it next to the assembly platform.

[0041] Step S18: The compartment moves between workstations on the assembly platform by rolling. During the movement, it is assembled into a complete missile and then picked up by the gantry handling robot and placed on the cartridge loading platform for assembly. Empty pallets / material boxes that are left out during the assembly process are rolled onto AGVs and then transferred to the corresponding storage locations.

[0042] Step S19: After the cartridge is loaded, it is moved to the AGV by rolling, then transferred to the test area and rolled to the test platform to complete the electrical performance related tests.

[0043] Step S20: After the test, the cartridge is transferred to the AGV by rolling and then transported to the testing area; it is then moved to the inspection platform by rolling and for mechanical property testing.

[0044] Step S21: After the inspection is completed, the cartridge rolls and moves to the AGV, and then is transported to the temporary buffer station in the export area to wait for the inter-factory logistics vehicle to transfer it to the finished product warehouse (outside the factory) for storage; then the AGV transports the pallet to the storage location.

[0045] Step S22: Repeat steps S14 to S21 to complete the daily production tasks.

During the installation process, the auxiliary positioning module quickly ensures that the cabin's position and attitude on the pallet meet the process requirements. Step S4: Scan the code to assemble the compartment and pallet, and the pallet containing the compartment is rolled and moved to the compartment AGV; Step S5: After placing the material box on the loading platform, scan the barcode to enter the warehouse, and the material box will roll and move to the compartment AGV; Step S6: Instruct the AGV of the compartment to transfer the pallet and material box containing the compartment to the non-fire-related product automated warehouse for storage; Step S7: Repeat steps S1 to S6 until the batch storage of non-fire-related products is completed. Step S8: One day before the start of the installation, the operator submits a batch of fire-related product warehousing application through the central control module terminal in the centralized material loading platform at the factory entrance. The fire-related product flat warehouse will take out the compartment or cylinder pallet and roll it to the full-explosive AGV. Step S9: Move the full-elastic AGV to transfer the pallet to the centralized loading platform and roll it to the loading platform; Step S10: Install the compartment or cylinder onto the pallet. During the installation process, the auxiliary positioning module enables the compartment or cylinder to quickly meet the process requirements in terms of placement position and orientation on the pallet. Step S11: Scan the code to assemble the compartment or cylinder with the pallet, and then the pallet containing the compartment or cylinder is rolled and moved to the full-explosive AGV; Step S12: Have the AGV transport the pallet containing the compartments or cylinders to the fire-related product storage area for storage. Step S13: Repeat steps S8 to S12 until the batch storage of fire-related products is completed; Step S14: On the day of installation, the operator issues the work plan for the day through the central control terminal or workstation terminal, and retrieves the tooling or fixtures to be used that day from the tool or fixture intelligent storage repository. Step S15: The compartments, material boxes or cylinders of the fire-related product flat warehouse and the non-fire-related product automated warehouse are respectively taken out of the warehouse and rolled onto the AGV; Step S16: The AGV transports the above materials to the full ammunition assembly area and the cartridge loading platform respectively, and moves them to the corresponding platforms by rolling; namely, the material conveying platform on the material box, the full ammunition assembly platform on the compartment, and the cartridge loading platform on the cartridge. Step S17: During the assembly process of the entire missile on the assembly platform, the ground rail robot grabs the material box containing the missile's direct parts, standard parts, etc., and places it next to the assembly platform. Step S18: The compartment moves between workstations on the assembly platform by rolling. During the movement, it is assembled into a complete projectile. Then, the gantry handling robot grabs it and moves it to the cannonball loading platform for assembly. Empty pallets or material boxes that are left out during the assembly process are rolled onto AGVs and then transferred to the corresponding storage locations. Step S19: After the cartridge is loaded, it is moved to the AGV by rolling, then transferred to the test area and rolled to the test platform to complete the electrical performance related tests; Step S20: After the test, the cartridge is transferred to the AGV by rolling and then transported to the testing area; it is then moved to the inspection platform by rolling and for mechanical property testing. Step S21: After the inspection is completed, the cartridge rolls and moves to the AGV, and then is transported to the temporary buffer station in the export area to wait for the inter-factory logistics vehicle to transfer it to the outside of the finished product warehouse for storage; then the AGV transports the pallet to the storage location. Step S22: Repeat steps S14 to S21 until the daily production tasks are completed; Repeat steps S13 and S22 until the batch production task is completed.
