Problems solved by technology

[0005] The purpose of the present invention is to address the low degree of automation, the huge amount of manual calculations, the huge amount of filling in documents, the unreasonable order of matching, and the need to browse and search for paper documents in the assembly production process of high-precision and complex products such as aviation, aerospace, and military industry. It is extremely difficult, prone to human error, and the efficiency of assembly materials is extremely low. Invent a method for automatic assembly of high-precision and complex products.

Embodiment Construction

[0040] The present invention will be further described below with reference to the drawings and implementation examples.

[0041] Such as Figure 1-21 Shown.

[0042] A method for automatically arranging assembly materials for high-precision and complex products, which includes the following steps:

[0043] First, according to the model and batch information of the product to be assembled, the process designer retrieves the assembly CAD model from the PDM system. Call the CAD secondary development interface program, apply recursive algorithm to traverse unstructured CAD model files, read the structure topology information of CAD files and the basic attribute information of components, parts, and standard parts in batches, and automatically create structured assembly materials by the program And the assembly BOM, stored in the assembly material complete database AIRM_DB.

[0044] Second, for each product to be assembled, a new product item number and a new material matching number are...

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 invention relates to a mechanical and electrical product assembly manufacturing technology, in particular to an automatic assembly method of assembly materials for high-precision and complex products. It automatically constructs assembly material complete sets of requirements and automatically calculates the complete sets of materials through assembly BOM for structurally complex products. Automatic generation of orders, automatic tracking of single materials, intelligent optimization of material matching sequence, automatic generation of material matching tables, automatic statistics of material complete sets of lists, automatic statistics of material missing parts lists, and material complete sets of information query, specifically a high-precision The method of automatic assembly of complex product assembly materials. Background technique [0002] Aviation, aerospace, military and other high-precision and complex products have high safety and reliabi...
