Automatic matching method for high-precision complex product assembling materials

Abstract

The invention discloses an automatic matching method for high-precision complex product assembling materials. The method is characterized by including: traversing and extracting unstructured assembling CAD (computer-aided design) model information through recursive algorithm, and automatically fast building a structured product assembling BOM (bill of material); iterating node layers of the assembling BOM to automatically calculate independent material requirements and related material requirements, and fast and accurately generating material requirement tables; acquiring materials in a matched manner through material requirement table separation, automatic material acquisition list circulation, online signing and examining, single material acquisition registration, and FRID (radio frequency identification); automatically and accurately calculating material shortage lists through assembling BOM iteration and reading of matched material acquisition lists and material matching lists; intelligently optimizing matching sequence through particle swarm optimization, and fast performing optimized material matching; automatically acquiring material information and automatically tracking single material through convenient RFID; and fast inquiring product material matching information through multi-condition optional combination vague inquiry. By the method, automation and intelligence of assembling material matching is increased, and assembling time is shortened.

Description

technical field [0001] The present invention relates to an assembly and manufacturing technology of mechanical and electrical products, especially a method for automatic assembly of assembly materials for high-precision and complex products. It automatically constructs assembly materials through the assembly BOM for complex-structured products. Automatic generation of bills, automatic tracking of material single pieces, intelligent optimization of material matching sequence, automatic generation of material matching tables, automatic statistics of complete material lists, automatic statistics of missing parts lists, and information query of complete sets of materials. Specifically, it is a high-precision A method for automatic alignment of complex product assembly materials. Background technique [0002] The safety and reliability requirements of high-precision and complex products such as aviation, aerospace, and military industry are very high, but their structures are oft...
