[0002] During the assembly of aircraft components, process specifications carry key information such as the process flow, process methods, materials, and digital models required for assembly. These specifications directly impact assembly quality and are a crucial step in assembly process preparation. Process specification planning, based on process plans, process experience, and design digital models, breaks down assembly work into multiple independently executable process specifications. The execution sequence of these process specifications, as well as the material composition at each process node, are planned. The process planning process is the core of assembly process preparation and plays a decisive role in ensuring the quality of the process specifications.

[0003] In traditional assembly processes, process specifications often rely on manual experience. During the planning process, process engineers spend a significant amount of time identifying digital models and adjusting planning schemes. This results in a high volume of repetitive and tedious work and low efficiency. This not only prolongs the assembly process cycle, but also reduces standardization and can even lead to quality errors. Summary of the Invention

DETAILED DESCRIPTION

[0017] Example 1: A method for planning airframe manufacturing process procedures based on material allocation, such as Figure 1 As shown, the specific steps include: Step S1: Establish a mapping model between assembly scenarios, process specification templates, and process specification materials.

[0018] 1.1 Define assembly scenarios, process specification templates, and process specification materials.

[0019] (1) Define the assembly scenario set C as: C =[ c 1, c 2,…, c n ]; in, c n Represents the nth type of assembly scenario, where n is the number of assembly scenario types. For example, skeleton structure assembly, parts bonding, system duct assembly, and other types of assembly scenarios.

[0020] (2) Define the process specification template set A as: A =[ a 1, a 2,…, a m ]; in, a m Represents the mth type of process specification template, where m is the number of process specification template types. For example, there are positioning templates, hole-making templates, installation templates, and bonding templates.

[0021] (3) Define the process material set M as: M =[ m 1, m 2,…, m j ]; in, m j Indicates the jth type of process material, where j is the number of process material types. For example, process materials such as skeleton components, connectors, rubber strips, and conduits.

[0022] 1.2 According to the process flow and production mode, formulate process procedure templates for different assembly scenarios and establish a mapping model between assembly scenarios and process procedure templates.

[0023] (1) Develop a general assembly process flow based on the assembly form and assembly plan for each assembly scenario.

[0024] For example, Figure 2 As shown, for the assembly scenario of a skeleton structure, the general process flow is positioning - hole making - installation, involving three process specification templates. For the assembly scenario of parts bonding, bonding can be completed entirely within a single template, involving one template. For the assembly scenario of system conduit harnesses, the process can be completed through the three processes of laying - pre-installation - installation, involving three templates.

[0025] (2) Different production methods are generated based on factors such as assembly management methods and factory planning, which can be divided into the following three categories: ① Directly adopt the general assembly process and customize the process specification template for each process.

[0026] ②Merge common assembly process flows to adapt to the centralized production form of actual production and process status management.

[0027] ③ Split the general assembly process flow to adapt to the refined division of labor production form of actual production and process status management.

[0028] For example, for a centralized production approach to skeleton assembly, positioning and hole making can be combined into a pre-assembly process, resulting in an optimized process flow: pre-assembly - installation. For a more refined production approach to skeleton assembly, hole making and installation can be separated according to the work pace. The final overall assembly process is: positioning - cold extrusion initial hole - cold extrusion - hole making - countersinking - pallet nut installation - bolt installation - inspection, involving a total of eight process specification templates.

[0029] (3) Establish a mapping model between assembly scenarios and process procedure templates.

[0030] like Figure 2 As shown in Figure 1, each assembly scenario corresponds to a set of process specification templates to express its assembly process flow. There is a one-to-many matching relationship between assembly scenarios and process specification templates.

[0031] 1.3 Establish a mapping model between process specification templates and process specification materials.

[0032] (1) According to the assembly content of the process specification template under different assembly scenarios, determine the assembly object of the process specification template, that is, the material inside the process specification template.

[0033] For example, Figure 3As shown, positioning templates need to specify which components to be positioned; hole-making templates need to specify which connecting holes between which components need to be made; installation templates need to specify which connecting parts to use and which components to connect and combine; bonding templates need to specify the adhesive strips to be used and which components to be bonded; pipe laying templates need to specify which conduit components to lay and the pipe joints between the conduits; pipe pre-installation templates need to specify which conduits to fix through which pipe clamps or clamps; pipe installation templates need to specify which connecting parts to use and which clamps and pipe clamps to fix.

[0034] (2) According to the type of process specification template, formulate the outbound plan for different process specification materials in the process specification template.

[0035] A variety of materials are required in the process specification template. Different materials have different functions. Materials that are to be used in the assembly process of the process specification and have not been shipped out of the previous process need to be shipped out. Materials that are to be used in the assembly process of the process specification but have been shipped out of the previous process only play an auxiliary assembly role in this process specification and do not need to be shipped out.

[0036] The same material may appear in multiple process specifications and play different roles in different process specifications. However, for production material shipments, the same material can only be shipped once in the production material list of different process specifications, and each material must be shipped.

[0037] (3) Establish a mapping model between process specification templates and process specification materials.

[0038] like Figure 3 As shown, each process specification template corresponds to multiple process specification materials to complete the assembly work within its assembly process. Each assembly material also corresponds to multiple process specification templates, creating a many-to-many relationship between process specification templates and process specification materials. Each relationship between a process specification template and a process specification material includes a delivery attribute to ensure that the assembly process is not over-assembled or missing materials.

[0039] Step S2: Based on the results of the three-dimensional digital model analysis, by constructing a parts assembly relationship diagram, the assembly relationship links between the materials in the assembly are opened up, and different assembly relationships are identified according to the feature matching method.

[0040] 2.1 Determine the assembly relationships involved in the assembly scenario.

[0041] Based on the different expressions of the design digital model, the assembly relationships involved in the assembly scenario are determined. Taking the three assembly scenarios of skeleton structure assembly, parts bonding, and system duct assembly as examples, they correspond to the following three assembly relationships: (1) If Figure 4 As shown in the figure, (a) represents the assembly relationship involved in skeleton structure assembly. Skeleton structure assembly corresponds to a connection relationship. A connection relationship involves creating holes in the materials to be connected, inserting fasteners such as rivets, pins, bolts, and screws into the holes, and securing them with nuts and washers. This allows for the connection and fastening of multiple layers of materials. This primarily involves the use of fasteners such as bolts, pins, and rivets to secure two or more components together.

[0042] (2) If Figure 4 As shown in the figure, (b) represents the assembly relationship involved in system conduit assembly. System conduit assembly corresponds to a contact relationship. Contact relationships are achieved by securing the materials to be assembled through form fit or binding, using clamps, pipe clamps, or key connections or bearing connections, thereby securing structures such as pipes, wiring harnesses, and pumps.

[0043] (3) If Figure 4 As shown in the figure, (c) represents the assembly relationship involved in part bonding. Part bonding corresponds to the bonding relationship. The bonding relationship is achieved by bonding parts together using adhesives or adhesive strips to achieve a combined assembly without connectors.

[0044] 2.2 Obtain the three-dimensional digital model of the parts, determine the connection relationship, bonding relationship, and contact relationship between the parts through the interference detection algorithm, and construct the parts assembly relationship diagram.

[0045] like Figure 4 As shown, the present invention lists three types of assembly relationships, namely, connection type, bonding type, and contact type, as examples.

[0046] 2.3 For each assembly relationship, define an assembly relationship retrieval scheme.

[0047] Regarding the connection relationship: using the connector as the intermediate hub, establish the connection relationship between the "material to be assembled", "connector", and "connector supporting material" of the same connector, and continue to expand to the periphery through different connectors of the "material to be assembled".

[0048] Regarding bonding relationships: Two bonding relationships can be established based on whether the transition material between the two parts to be bonded is a rubber strip component or an adhesive. If the transition material is a rubber strip component, a ternary bonding relationship is established with the rubber strip component as the intermediate hub; if the transition material is an adhesive, a binary bonding relationship is established through an interference relationship.

[0049] Regarding contact relationships: Based on the interference relationship, a contact relationship chain between multiple materials is established to form a multi-dimensional contact relationship.

[0050] 2.4 Using the traversal retrieval method, in the parts assembly relationship diagram, different assembly relationship retrieval schemes are used for traversal retrieval according to different assembly scenarios. If there is a set of assembly relationships that meets the characteristics of the retrieval scheme, it is identified as the corresponding set of assembly relationships.

[0051] Step S3: Define the material range for different assembly scenarios and establish a mapping model between all product materials and the materials within the minimum assembly unit.

[0052] 3.1 Define the material range Q for different assembly scenarios, which can be expressed as: ; in, Represents all materials in a certain assembly scenario, Indicates the first Category material range, The number of types in the material range, for example, the material range of skeleton components, conduits, pipe fittings, etc.

[0053] For each type of material range, the material range under the EBOM structure tree of different product models is defined using the regular formula method in the form of name keywords or drawing number keywords.

[0054] 3.2 According to the design digital model structure and the manufacturing concept of the product assembly unit (Wang Cheng, Xu Jianxin. Graphical assembly process planning technology for complex products based on consumable bill of materials conversion [J]. Mechanical Manufacturing, 2020, 58(5):6.DOI:CNKI:SUN:JXZG.0.2020-05-004.), the material range of the assembly scenario is divided into the granularity form of the smallest assembly unit that can be assembled independently at one time, that is, all materials within the material range of the assembly scenario are split into multiple minimum assembly units.

[0055] The minimum assembly unit is the assembly object of the process specification. The materials inside the minimum assembly unit are the input information for the compilation of the process specification, involving the components and standard parts information in the digital model.

[0056] 3.3 Establish a mapping model between all product materials and the materials within the minimum assembly unit.

[0057] like Figure 5 As shown in the figure, all the materials of the product are divided into different material ranges according to the assembly scenario. The material range under each assembly scenario is divided into multiple minimum assembly units, thereby establishing a mapping model between all the materials of the product and the materials within the minimum assembly unit.

[0058] Step S4: Plan the assembly sequence of the minimum assembly unit and the assembly sequence of the corresponding process procedure nodes.

[0059] 4.1 Based on the actual assembly process plan, assembly simulation conditions, and the spatial position sequence of the designed digital model structure, formulate a process flow, sort the assembly sequence of the minimum assembly units, and plan the spatial assembly sequence of the assembly scenario.

[0060] 4.2 Plan the assembly sequence between process specification templates based on the assembly process in the assembly scenario, plan and sort all process specifications, and plan the numbering and names of process specification nodes according to the coding and naming principles.

[0061] Step S5: Establish a mapping model between the minimum assembly unit and the process specification template and process specification node, allocate the materials in the minimum assembly unit to the corresponding process specification node, and realize process specification planning based on material allocation.

[0062] 5.1 Establish a mapping model between the minimum assembly unit and the process specification template and process specification node.

[0063] like Figure 6 As shown, each minimum assembly unit corresponds to a set of process specification templates, and a set of process specification templates corresponds to multiple process specification nodes with the same template.

[0064] 5.2 Allocate the materials in the minimum assembly unit to the corresponding process procedure nodes.

[0065] According to the mapping model between all materials of the product and the minimum assembly unit, materials are allocated to each process procedure node to realize process procedure planning based on material allocation.

[0066] Materials under the process specification node come from materials within the minimum assembly unit and have a delivery type attribute. The delivery type consists of two types: M{delivery, not deliver}.

[0067] All materials within the smallest assembly unit with the outbound type attribute are assigned to the corresponding process nodes. Based on the materials assigned to the process nodes, the process nodes for specific materials in each assembly scenario and the planning of materials under the process nodes are completed.

[0068] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the scope of protection of the present invention.
