Problems solved by technology

The current theoretical research is more trying to solve this problem automatically by establishing a complete mathematical theory, but due to the lack of an effective description mechanism for product information (constraint information), human knowledge and experience, even if the geometric calculation method The amount of computation required to obtain part of the constraint relationship of the product is very large, which is the direct cause of the current research theory (method) dilemma in engineering feasibility

Embodiment Construction

[0050] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0051] figure 1 It is a structural diagram of a system embodiment of the present invention. As shown in the figure, the electromechanical product disassembly planning system of this embodiment includes: a disassembly information model building module 11, which is used to load a three-dimensional CAD model 15 of a product, and read parts to be disassembled. Component data information, so as to build the disassembly feasibility information graph (Disassembly Feasibility Information Graph, DFIG) model of the product; priority relationship collection module 12, used to judge and define the known disassembly priority relationship of some parts; disassembly plan generation module 13. Combined with the defined disassembly priority relationship, use the comprehensive algorithm of ant colony optimization theory to solve the DFIG model to obtain...

Abstract

The invention relates to a method for planning the disassembly of electromechanical products. The method comprises the following steps: the three-dimensional CAD model of a product is loaded, and data information of parts to be dismounted is read, thereby constructing the information graph model of feasibility for dismounting the product; the given dismounting precedence relation of partial components is judged and defined; with the combination of the defined dismounting precedence relation, the information graph model of dismounting practicability is solved by utilizing the integration algorithm of ant colony optimization, so as to obtain a product dismantlement scheme. The invention further discloses a corresponding system and a method for managing disassembly information of electromechanical products and a system thereof. The technical scheme of the invention is characterized in that the analysis and evaluation for planning performance can be realized through an intelligent optimization algorithms and part of human-computer interaction work, so as to help a designer to improve the product disassembly recyclability and prolong the traditional product design chain; and the process file of the dismantlement scheme is encapsulated By utilizing RFID label, so as to guide disassembly and recovery process of product when the life cycle is ended.

Description

technical field [0001] The present invention relates to the field of computer-aided product design, in particular to a method and system for disassembly planning and disassembly information management of electromechanical products based on ant colony optimization theory and RFID (Radio Frequency Identification, radio frequency identification) technology. Background technique [0002] my country is a big consumer of electronic and electrical products. In recent years, with the rapid development of the electronic and electrical industry and the acceleration of the renewal of electronic and electrical products, a large number of waste electronic and electrical products are also produced. In the next few years, my country's waste and used electronic and electrical products will cost 15-25 per year. % growth rate. Due to the characteristics of both hazardous and resource-based waste electronic and electrical products, it is very necessary to promote the research on their recycling...
