Abstract

The invention provides a robot vision guide method used for shaft hole assembling. An industrial camera is used for taking an image of a hole system workpiece, obtaining the image data of the hole system workpiece and transmitting the image data to an upper computer. The upper computer carries out image processing and analysis on the image data, and the image data of the center position and the radius of each shaft hole of the hole system workpiece on the image are obtained. The image coordinate data of each shaft hole are converted into coordinate data of a robot coordinate system. The robot coordinate data are sent to a robot controller, and therefore vision guide work is completed. The robot vision guide method used for shaft hole assembling improves the accuracy and stability of intelligent assembling with an industrial robot, and improves the automation degree.

Description

technical field [0001] The invention relates to the field of robot control, in particular to a robot vision guidance method for shaft hole assembly. Background technique [0002] In modern manufacturing, industrial robots are widely used in various production needs, such as welding, spraying, palletizing, assembly, etc. It can not only liberate workers from complicated labor tasks, but also improve the quality of products and the automation level of production lines, greatly improving work efficiency. Especially, in the part assembly production task, the multi-axis hole assembly task is one of the common task types. In this case, multiple pairs of shaft holes have assembly relationships at the same time, and industrial robots are required to automatically and accurately position while satisfying the correct assembly correspondence. More importantly, there is a need to avoid collisions between the two workpieces which could lead to defects. Therefore, it can be seen that t...
