[0053] Example 1:

[0054] A method for planning a body manufacturing process procedure based on material distribution, as shown in the following figure, specifically includes the following steps: Figure 1

[0055] Step S1: Establish a mapping model between assembly scenarios, process procedure templates, and process procedure materials.

[0056] 1.1 Define assembly scenarios, process procedure templates, and process procedure materials.

[0057] (1) Define an assembly scenario set C as:

[0058] C [ c 1, c 2, …, c n ];

[0059] wherein c n represents the nth type of assembly scenario, and n is the number of assembly scenario types. For example, types of assembly scenarios include skeleton structure assembly, part bonding, system conduit assembly, etc.

[0060] (2) Define a process procedure template set A as:

[0061] A [ a ​1, a 2, …, a m ];

[0062] wherein, a m denotes the mth type of process procedure template, m is the number of process procedure template types. For example, positioning template, hole making template, installation template, bonding template, and other types of process procedure template.

[0063] (3) Define the process procedure material set M as:

[0064] M =[ m 1, m 2, …, m j ];

[0065] wherein, m j denotes the jth type of process procedure material, j is the number of process procedure material types. For example, skeleton component, connecting piece, adhesive tape, conduit, and other types of process procedure material.

[0066] 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.

[0067] (1) According to the assembly form and assembly scheme of each assembly scenario, formulate a general assembly process flow.

[0068] For example, as shown in Figure 2 , for the assembly scenario of skeleton structure assembly, the general process flow is positioning-hole making-installation, involving 3 process procedure templates. For the assembly scenario of part bonding, the bonding work can be completed in one template, involving 1 template. For the assembly scenario of system conduit bundle assembly, it can be completed through laying-pre-installation-installation, involving 3 templates.

[0069] (2) According to factors such as assembly management mode and plant planning, different production modes can be produced, which can be divided into the following three categories:

[0070] ① Directly use the general assembly process, and customize process procedure templates for each process.

[0071] ② Merge the general assembly process to adapt to the centralized production form of actual production and process state management.

[0072] ③ Split the general assembly process to adapt to the fine division production form of actual production and process state management.

[0073] For example: the work of skeleton structure assembly is centralized production mode, positioning, hole making is combined into pre-assembled form, the optimized process flow is: pre-assembled installation. For the skeleton structure assembly, the work of hole making and installation can be split according to the work rhythm, and finally the whole assembly is split, the process flow is: positioning, cold extrusion initial hole, cold extrusion, hole making, counterbore, nut installation, bolt installation, inspection, which involves 8 types of process procedure templates.

[0074] (3) Establish the mapping model between the assembly scene and the process procedure template.

[0075] As shown in Figure 2 , each assembly scene corresponds to a set of process procedure templates to express its assembly process flow. The matching relationship between assembly scene and process procedure template is one-to-many.

[0076] 1.3 Establish the mapping model between the process procedure template and the process procedure material.

[0077] (1) According to the assembly content of the process procedure template under different assembly scenes, determine the assembly object of the process procedure template, that is, the material inside the process procedure template.

[0078] For example, as shown in Figure 3 , the positioning template needs to specify which components to be positioned; the hole making template needs to specify which connecting holes between which components to be made; the installation template needs to specify which connecting pieces to be used to connect and combine which components; the bonding template needs to specify which adhesive strips to be used and which components to be bonded; the pipeline laying template needs to specify which conduit components to be laid and which pipe joints between the conduits; the pipeline pre-installation template needs to specify which pipe clamps or clamps to be used to fix which conduits; the pipeline installation template needs to specify which connecting pieces to be used to fix which clamps and pipe clamps.

[0079] (2) According to the type of process procedure template, develop the delivery plan of different process procedure materials in the process procedure template.

[0080] There are multiple materials in the process procedure template, and different materials have different functions. For the materials to be used in the process procedure assembly process, and the materials that have not been delivered in the previous process, they need to be delivered; for the materials to be used in the process procedure assembly process, but the materials have been delivered in the previous process, only play a supporting role in the assembly process, then they do not need to be delivered.

[0081] The same material may appear in multiple process procedures and play different roles in different process procedures. However, for the delivery of production materials, the same material can only be delivered once in the production material list of different process procedures, and each material needs to be delivered.

[0082] (3) Establish a mapping model between the process procedure template and the process procedure material.

[0083] As shown in Figure 3 , each process procedure template corresponds to multiple process procedure materials to complete the assembly work in its assembly process. Each assembly material also corresponds to multiple process procedure templates, and the relationship between the process procedure template and the process procedure material is many-to-many. The relationship between each process procedure template and the process procedure material has an attribute of whether to export, to ensure that the field frequency assembly result does not have too many or missing materials.

[0084] Step S2: Based on the three-dimensional model analysis result, the assembly relationship link between materials in the assembly body is connected through the construction of a part assembly relationship graph, and different assembly relationships are identified according to a feature matching method.

[0085] 2.1 Determine the assembly relationship involved in the assembly scenario.

[0086] According to different expression forms of the design model, determine the assembly relationship involved in the assembly scenario. Take three assembly scenarios of skeleton structure assembly, part bonding, and system conduit assembly as examples, which correspond to the following three assembly relationships respectively:

[0087] (1) As shown in Figure 4 , (a) therein is the assembly relationship involved in the skeleton structure assembly. The skeleton structure assembly corresponds to the connection relationship. The connection relationship is to realize the connection and fastening of multiple materials by drilling holes on the materials to be connected, putting rivets, pins, bolts, screws, etc. into the drilled holes, and fixing them with nuts and washers. It mainly involves the assembly method of using bolts, pins, and rivets to fix two or more components together.

[0088] (2) As shown in Figure 4 , (b) therein is the assembly relationship involved in the system conduit assembly. The system conduit assembly corresponds to the contact relationship. The contact relationship is to realize the fixation of pipelines, wire harnesses, and pumps by using clamps, pipe clamps, or key connections and bearing connections to make the materials to be assembled contact through shape fitting or binding.

[0089] (3) As shown in Figure 4 , (c) therein is the assembly relationship involved in the part bonding. The part bonding corresponds to the bonding relationship. The bonding relationship is to complete the bonding between parts by using adhesive or adhesive tape to realize the assembly without connecting components.

[0090] 2.2 Obtain the three-dimensional model of the parts, determine the connection relationship, bonding relationship and contact relationship between the parts through the interference checking algorithm, and construct a part assembly relationship diagram.

[0091] As shown in Figure 4 , the present application lists three assembly relationships of connection, bonding and contact as examples.

[0092] 2.3 For each type of assembly relationship, define an assembly relationship retrieval scheme.

[0093] For connection relationship: through the connecting piece as the intermediate pivot, the connection relationship between the "to-be-assembled material", the "connecting piece", and the "connecting piece matching material" of the same connecting piece is established, and through the different connecting pieces of the "to-be-assembled material", the expansion to the surrounding is continued.

[0094] For bonding relationship: according to the transition material between the two parts to be bonded, whether it is a glue strip part or an adhesive, two kinds of bonding relationships are established. If the transition material is a glue strip part, a ternary bonding relationship is established through the glue strip part as the intermediate pivot; if the transition material is an adhesive, a binary bonding relationship is established through the interference relationship.

[0095] For contact relationship: according to the interference relationship, the contact relationship chain between multiple materials is established, forming a multi-element contact relationship.

[0096] 2.4 Using the traversal retrieval method, in the part assembly relationship diagram, different assembly relationship retrieval schemes are used for traversal retrieval according to different assembly scenarios. If there is a group of assembly relationships that meet the characteristics of the retrieval scheme, it is identified as the corresponding group of assembly relationships.

[0097] Step S3: define the material range of different assembly scenarios, and establish a mapping model of all product materials and internal materials of the smallest assembly unit.

[0098] 3.1 Define the material range Q of different assembly scenarios, which can be expressed as:

[0099] ;

[0100] Among them, represents all materials under a certain assembly scenario, represents the class material range corresponding to the assembly scenario, is the type number of the material range, for example, skeleton subassembly, conduit, pipe joint, etc.

[0101] For each type of material range, the method of regular formula is used to define the material range under the EBOM structure tree of different model products through the form of name keyword or figure number keyword.

[0102] 3.2 According to the form of design digital model structure and the manufacturing concept of product assembly unit (Wang C, Xu J X. Complex product graphical assembly process planning technology based on consumption bill of materials conversion [J]. Mechanical Manufacturing, 2020, 58(5): 6. DOI: CNKI: SUN: JXZG.0.2020-05-004.), the material range of assembly scene is divided into the granularity form of minimum assembly unit that can be independently assembled at one time, that is, all materials in the material range of assembly scene are split into multiple minimum assembly units.

[0103] The minimum assembly unit is the assembly object of process plan, and the materials inside the minimum assembly unit are the input information for process plan compilation, which involves the information of components and standard parts in digital model.

[0104] 3.3 Establish the mapping model of all product materials and internal materials of minimum assembly unit.

[0105] As shown in Figure 5 , all product materials are divided into different material ranges according to assembly scenes, and the material range under each assembly scene is divided into multiple minimum assembly units, thereby establishing the mapping model of all product materials and internal materials of minimum assembly unit.

[0106] Step S4: Plan the assembly sequence of minimum assembly unit and the assembly sequence of corresponding process plan node.

[0107] 4.1 According to the actual assembly process scheme, assembly simulation, spatial position sequence of design digital model structure, formulate process flow, sort the assembly sequence of minimum assembly unit, and plan the spatial assembly sequence of assembly scene.

[0108] 4.2 According to the assembly flow under the assembly scene, plan the assembly sequence between process plan templates, sort all process plans, and plan the number and name of process plan nodes according to the coding principle and naming principle.

[0109] Step S5: Establish the mapping model between minimum assembly unit and process plan template, process plan node, distribute the materials in minimum assembly unit to the corresponding process plan node, and realize the process plan based on material distribution.

[0110] 5.1 Establish the mapping model between minimum assembly unit and process plan template, process plan node.

[0111] As shown in Figure 6 , each minimum assembly unit corresponds to a group of process plan templates, and a group of process plan templates corresponds to multiple process plan nodes of the same template.

[0112] 5.2 Distribute the materials in the minimum assembly unit to the corresponding process procedure node.

[0113] According to the mapping model of all materials of the product and the minimum assembly unit, distribute the materials to each process procedure node, and realize the process procedure planning based on the material distribution.

[0114] The materials under the process procedure node come from the materials in the minimum assembly unit, and have the warehouse-out type attribute. The warehouse-out type consists of M{warehouse-out, no warehouse-out}.

[0115] Distribute all the materials in the minimum assembly unit with the warehouse-out type attribute to the corresponding process procedure node. Based on the materials distributed in the process procedure node, the planning of the process procedure node and the materials under the process procedure node of the specific materials in each assembly scenario is completed.

[0116] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification or equivalent change made according to the technical essence of the present application to the above embodiment falls within the protection scope of the present application.
