Description

PBOM-based associated material construction method, equipment and medium

Technical Field

The invention relates to the technical field of product data management, in particular to a PBOM-based associated material construction method, equipment and medium.

Background

The lean production organization form based on BOM enables the information transmission of enterprises to be more efficient, the production mode to be more flexible, and the defects of traditional manufacturing are overcome. How to more efficiently use the PBOM to realize the informatization requirement of the enterprise is the key point of research of the technicians in this field.

Currently, the reconstruction research of PBOM mainly focuses on the combination of parts under a whole piece, and is biased to establish an assembly hierarchical relationship, for example:

the fuzzy clustering method for aircraft process component division is provided in the literature (Ma Heng, shou Yi, open Rich. fuzzy clustering method for aircraft process component division [ J ]. aviation manufacturing technology [ J ],2006(09):73-76+81), a main body structure is determined by establishing an assembled hierarchical relation tree, and membership is judged by an algorithm on the basis of a fuzzy relation matrix for other unplanned materials.

The literature, "assembly process planning technology research analysis for aviation products" (xu qing, queen, cai jin. assembly process planning technology research analysis for aviation products [ J ]. aviation science, 2014,25(05):57-62.) is substantially the same as the literature, and proposes that a type hierarchical tree for structural member assembly is firstly established, a main structure for process component division is established, then a fuzzy clustering method is utilized to calculate the membership degree between the residual process components and the adjacent process components, and a process component division scheme is determined after judgment.

In the document of 'complex product three-dimensional assembly process micro-programming object model' (Xuzhijia, Liyuan, Yujiafeng, etc.. complex product three-dimensional assembly process micro-programming object model [ J ]. computer integrated manufacturing system, 2011,17(04):701 plus 710.), the assembly process planning is proposed to be divided into two steps: 1) assembly process macro planning, namely, from the perspective of a total process scheme, performing component-level assembly process component division and assembly sequence design among the component-level assembly process components; 2) and (3) assembling process micro-planning, namely, from the perspective of detailed assembling operation, performing assembling sequence design and assembling path design in the process assembly, and performing simulation verification on the assembling sequence design and the assembling path design.

For quadratic reconstruction of PBOM, one of the important aspects is to perform material recombination. Part of materials can be used at multiple levels simultaneously, and according to the EBOM structure tree, online control cannot be realized, and only offline manual processing can be realized. Aiming at the problem, no better solution thought exists at present.

In specific application, the PBOM is reconstructed through the associated materials aiming at 4 production organization scenes including a cross-layer trialassembly demand scene 1, anassembly demand scene 2, a completeset pickup scene 3 and a jointdebugging demand scene 4. Meanwhile, the related materials are divided into virtual related materials and entity related materials, and the suffixes of the codes are V (virtual) and R (entity) respectively.

Example 2

On the basis ofembodiment 1, when the production organization scenario is a scenario based on cross-level trial assembly requirements, step S3 includes the sub-steps of:

s311, in the process overall planning stage in the CAPP system, planning of overall procedures, product sub-level materials, tools, instruments, equipment, auxiliary materials, fields and the like is mainly carried out according to the characteristics of products, resource allocation, production cycle, cost and quality are comprehensively considered, and the optimal process flow is determined. Analyzing the cross-level trial assembly requirement, analyzing whether trial assembly is needed in the assembly process according to whether the cost of the trial assembly is less than the risk caused by no trial assembly or not and whether the materials required by the trial assembly are different at the parent node of the PBOM or not aiming at specific whole pieces/parts, and entering step S312 if needed or ending if not needed; in the step, cross-layer trial assembly requirement analysis is to analyze whether trial assembly is needed in the assembly process of a specific whole piece/component, and materials needed by the trial assembly are different in a parent node of the PBOM.

And S313, in a material reconstruction stage in the CAPP system, the PBOM is reconstructed, the existing materials are packaged, disassembled and adjusted in position, and the materials missing from the original PBOM are supplemented so as to meet the material requirements of each procedure.

And step S313, compiling a trial assembly process, namely compiling a trial assembly process procedure card for the process assembly constructed in the step S313. In this step, the PBOM structure changes before and after the associated material is built as shown in fig. 6.

In the embodiment, trial assembly is often required in the assembly process, and the problems of interference, dislocation, hole site missing processing and the like are found in advance. The trial assembly is divided into same-level trial assembly and cross-level trial assembly, wherein the same-level trial assembly means that materials required by the trial assembly have the same father node in a PBOM structural tree, and the cross-level trial assembly means that the materials required by the trial assembly are different in the father node of the PBOM. The trial assembly is usually only suitable for parts at the same level, however, the EBOM is usually constructed according to the function level, so that the situation of cross-level trial assembly is often generated. How to realize the trial assembly among the cross-level parts is always a pain point of an enterprise. By constructing the associated materials, the requirement of cross-layer trial assembly is met, and the method has the following advantages: (1) the mapping of the materials is realized by constructing the associated materials, the cross-level trial assembly is converted into the same-level trial assembly, and the cross-level trial assembly is realized by adopting a same-level trial assembly PBOM reconstruction method.

In this step, the PBOM structure changes before and after the associated material is built as shown in fig. 7.

For example, the cable in the pure manual mode must determine the length of the lower wire, the binding position, etc. according to the actual routing path. The assembly requirement is hard to be embodied in the EBOM, and the assembly is realized by constructing the associated materials, so that the method has the following advantages: (1) the assembly can form an independent order, and is distinguished from the assembly process of the parts, so that the problems of process disorder, material circulation disorder and the like caused by the formation of multilayer task nesting are avoided. (2) After the initial manufacture is finished and the manufacturing parameters are recorded, the assembly node of the PBOM can be cancelled, and the PBOM maintenance is convenient.
