Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0031] Such as figure 1 As shown, this embodiment provides a product intelligent assembly method based on motion sub-surface recognition, the specific process of the method is as follows:

[0032] In step 101, each part of the product is obtained.

[0033] In step 102, the surface of each part is extracted, and the surfaces are classified to establish a set of behavioral surfaces for each part. The classification of part surfaces includes behavioral surfaces and non-behavioral surfaces.

[0034] Extract the surface of each part specifically as:

[0035] 201) Obtain the function-be...

Abstract

The invention relates to an intelligent product assembly method based on kinematic pair surface identification. The intelligent product assembly method based on kinematic pair surface identification comprises the following steps: (1) obtaining all the parts of the product; (2) extracting the surface of each part and classifying the surfaces to establish a behavior surface set of each part; (3) traversing the behavior surface set of each part, and then according to the kinematic pair surface pairing rule, obtaining the pairing surfaces of all the behavior surfaces to form an assembly solution; (4) evaluating the constraint degree of the assembly solution and judging whether the evaluating result meets the setting requirement or not, if so, executing step (5), if not, going back to step (3); (5) exporting the assembled products. Compared with the prior art, the method has the characteristics of being high in degree of automation, being accurate in assembly and like.

Description

technical field [0001] The invention relates to a product assembling method, in particular to an intelligent product assembling method based on the recognition of moving sub-surfaces. Background technique [0002] With the accelerated development of economic globalization and global informatization, the production mode of products is undergoing tremendous changes, gradually changing from a few varieties and large batches to a multi-variety and small batch production mode, and the product development time cannot adapt to the product life cycle. Keep shortening the asking questions. In the product development process, product assembly is one of the most important steps in the whole life cycle of product manufacturing, which consumes a lot of energy and time, and is the main process of realizing product functions. Therefore, product assembly design plays a decisive role in the overall product quality. [0003] The research on product assembly design mainly includes the evalua...
