The invention provides an automatic disassembling method for an assembly. The automatic disassembling method for the assembly comprises the following steps of: step 1, generating a digitization three-dimensional model corresponding to the assembly according to the actual structure and shape of the assembly; step 2, subjecting the model to a shape analysis to divide the model into a plurality of components, establishing directed contact relations among the components, and calculating occlusion relations among the components; step 3, calculating a hierarchical structure of the model according to geometrical characteristics of the components, dividing the model into a plurality of subassembly models, and calculating a decomposition direction of every subassembly model; step 4, calculating a decomposition sequence of the model according to the occlusion relations and the hierarchical structure of the model, wherein the decomposition sequence comprises decomposition sequences and decomposition motion directions of the components; and step 5, obtaining disassembling sequences and disassembling directions of the components of the assembly according to the decomposition sequence to complete the physical disassembling of the assembly. The automatic disassembling method for the assembly enables operators to disassemble complex assemblies efficiently.
Description
technical field [0001] The invention belongs to the cross-technical field of assembly disassembly and computer graphics processing, and in particular relates to a method for automatically disassembling an assembly by calculating the disassembly sequence and disassembly movement direction of each component of the assembly based on computer graphics processing. The invention uses the geometric features of the three-dimensional shape to analyze and understand the shape, especially to extract the high-level structure of the three-dimensional shape and analyze the motion of a single component. Background technique [0002] In the field of manufacturing, disassembly is a necessary means to realize product upgrading, maintenance and replacement. It can make the parts and materials of the product fully and effectively utilized, can be recycled, and reduce the demand for material resources and energy. The current disassembly process is done manually, and complex assemblies are often ...
