Problems solved by technology

[0003] Because the phase recognition feature holes reserved in the previous process (casting) of parts have not been processed, defects such as burrs, cast nodules and even out-of-roundness are more likely to occur. These unstable factors pose a higher challenge to the intelligentization of machine vision system recognition. Require

Embodiment Construction

[0020] The invention discloses a method for automatic identification of components in the process of mechanical assembly. This method constructs the component feature library in the mechanical component assembly process, which is used to realize the full automation of mechanical assembly. During the mechanical assembly process, it can gradually extract the features of the parts to be assembled and the parts to be recognized Part features are registered and recognized until the assembly is completed, which saves the tedious steps of manually specifying the parts required for each step of assembly during the assembly process, which can greatly save the time of mechanical assembly. In addition, when replacing the assembly machine, since the component feature library has been built, we only need to replace the component features in the component feature library without replacing the expensive hardware in the assembly process, which can greatly save production costs . In the proce...

Abstract

The invention discloses a component automatic recognition method for a mechanical assembly process. The method comprises the following steps of: the construction of a component assembly sequence library; the acquisition of component pile images; the feature extraction of the component pile images; the three-dimensional construction of the component pile images; the feature extraction of the component pile images; and the registration recognition of components. The component automatic recognition method of the invention has the advantages of simple principle, high efficiency, high detection precision, high robustness and the like.

Description

technical field [0001] The invention belongs to the technical field of parts recognition, and in particular relates to an automatic recognition method of parts in a machine vision-based mechanical assembly process. Background technique [0002] In modern large-scale production, it involves a variety of inspection, production monitoring and parts identification applications. Visual inspection is often an indispensable link. It requires many inspection workers to observe and inspect with the naked eye or combined with a microscope. A large number of inspections Labor not only affects factory efficiency, but also brings unreliable factors, which directly affects product quality and cost. In addition, most inspection processes not only require appearance inspection, but also accurate acquisition of inspection data, such as dimensional inspection of batch processing of spare parts, integrity inspection of automatic assembly, automatic positioning of components in electronic assem...
