Problems solved by technology

[0004] Chinese patent CN109571476A discloses a real-time operation control, monitoring and precision compensation method for digital twins of industrial robots. The improved method uses real-time joint data to drive the digital model of the robot, and uses the joint angle information of the real robot and the real-time joint angle information of the digital twin model. Comparing and updating the joint angle compensation, but this method only compensates the joint information of the robot, does not establish a physical model of the assembly system, and lacks generality

Abstract

The invention relates to a construction system of a digital twinning system for robot assembly. The construction system comprises a physical space, a digital space for bearing the digital twinning system, and a communication interface for connecting the physical space and the digital space, wherein the physical space comprises an assembling robot, assembling equipment, an assembling target object,a main end controller, an assembling environment and a digital sensor, and the digital sensor is installed in a working scene, collects geometrical information and physical information of the assembling robot, the assembling equipment, the assembling target object and the environment and sends the geometrical information and the physical information to the digital space through a communication interface. Compared with the prior art, the construction system has the advantages of comprehensive consideration of the virtual model and the like.

Description

technical field [0001] The invention relates to the field of intelligent assembly, in particular to a construction system of a digital twin system oriented to robot assembly. Background technique [0002] In the production process of an enterprise, the assembly operation requires a lot of manpower and material resources, which accounts for a large proportion of the entire production cost. With the continuous improvement of scientific research and technology, assembly robots have been developed and widely used in the manufacturing industry. However, due to the rapid development of industrial technology and information technology, the assembly industry has become more and more complex, resulting in an increase in assembly failure rates and maintenance costs. Therefore, accurate and real-time monitoring and optimization of robotic assembly process has gradually become a research hotspot. In order to meet and adapt to the needs and trends of manufacturing development such as so...
