Abstract

The invention discloses a method for detaching products based on a connected piece level network diagram, aiming to solve the problems of effectively recycling waste and old materials to reduce the waste of the materials, and solving the problems of energy consumption, pollution and the like caused by the production of raw materials. The method comprises the following steps of: extracting / inputting attribute information of parts, extracting / inputting assembly information of the products, building and detaching models, generating detaching sequences and optimizing the detaching sequence. In the invention, the connected piece level network diagram is used as the detaching model, and an adjacent matrix is utilized to represent the adjacent relationship between nodes. The node of the model only represents the connected parts, not all parts, thereby effectively reducing the number of the nodes and edges in the diagram, reducing the dimensionality of the adjacent matrix, reducing the calculation difficulty and improving the processing speed. The detaching sequence of the product is generated based on a method of constraint removal, so that the obtained detaching sequence has more valuable meaning and maneuverability.

Description

【Technical field】: [0001] The invention belongs to the technical field of advanced manufacturing and automation, and in particular relates to research on disassembly due to the effective recycling and reuse of products. 【Background technique】: [0002] Effective recycling and reuse of waste products not only reduces the waste of materials, but also reduces the energy consumption and pollution caused by raw material production. Disassembly is the basis of recycling and the prerequisite for effective product recycling and reuse. Disassembly sequence generation is an important part of disassembly research, which is the combination of parts disassembly sequence from the beginning of product disassembly to the release of all or part of the constraints between parts in the product. [0003] Among them, the disassembly model is the basis of disassembly research. The disassembly model should describe the information needed for disassembly key technology research as much as possible...
