Peg-in-hole assembly automatic centering system based on image processing

Abstract

The application discloses a peg-in-hole assembly automatic centering system based on image processing. The system comprises an image processing subsystem and a control subsystem. The image processing subsystem at least collects an image of a target bearing and obtains the displacement of a docking shaft deviated from the target bearing. The control subsystem receives an instruction of the image processing subsystem and controls the docking shaft to deviate by a specific displacement, so that the docking shaft and the target bearing are enabled to be centered. With the adoption of the method, defects that the efficiency of manual detection is low and the manual detection is time-consuming and labor-consuming can be tackled, and automobile axle hole automatic centering assembly can be scientifically and accurately performed.

Description

technical field [0001] The invention is based on video image processing, belongs to the technical field of industrial production assembly, and in particular relates to an automatic centering system for shaft hole assembly. Background technique [0002] Since entering the new century, especially since 2002, my country's automobile manufacturing industry has entered a period of rapid development. With the improvement of automobile manufacturing technology, my country's automobile manufacturing level has been greatly improved. However, compared with western developed countries, there is still a big gap. Among them, the accuracy of shaft hole assembly has always troubled the front-line production and manufacturing personnel. The assembly of auto parts involves a series of shaft hole assembly, such as the assembly of camshafts, half shafts, gearbox input and output shafts, and bearing holes. As an important part of automobile assembly, the shaft hole is separated before assembl...

Problems solved by technology

Any error in the assembly process may reduce the service life, increase wear, and cause great harm to the normal use of the workpiece

[0003] At present, the shaft hole assembly in the automobile production and assembly process still adopts the manual centering method. This kind of centering method relying on visual experience and manual adjustment is time-consuming and labor-intensive, the accuracy is not high, and it is unstable due to the fatigue of the human eye. Environmental constraints can no longer meet the needs of the production department, and an automatic and accurate alignment method is urgently needed
