Embodiment Construction

[0020] The light source in the present invention refers to a special light source for machine vision, which is used to provide illumination when the camera 1 collects images. The camera 1 is connected to the image acquisition card through the 1394 data line, and the image acquisition card is installed on the DSP. The industrial CCD camera 1 is installed above the loading platform, and the camera 1 is surrounded by a ring light source 5 . The selected DSP model is TMS320DM642, this type of DSP has powerful image processing capability and computing capability. The teaching box adopts MCS-51 series single-chip microcomputer to complete the receiving and sending of control signals. The DSP transmits the detected current position data of each axis to the single-chip microcomputer, and receives the control signals and teaching signals of each axis movement from the single-chip microcomputer. As the center of the control system, DSP integrates the six-axis motion control card throug...

Abstract

The invention provides a monocular vision material loading and unloading robot system of a numerical control lathe and a method thereof. A traditional material loading and unloading robot of the lathe is utilized, and an industrial camera is mounted at the upper part of a material bin; collected image signals are transmitted to a digital signal processor (DSP); and dimension characteristics of bar materials of the lathe are determined through utilizing the DSP to process the collected images. The grasping scheme of parts is determined according to a comparison of the dimension characteristics and data in a part library in an industrial control computer. The loading and the unloading of the bar material of each type need to be manually taught for the first time; and if the bar material of the type occurs once more, the DSP calls out a material loading and unloading scheme and an intelligent recognizing and grasping scheme of the bar material of the type through comparing the bar material with the images collected in the part library, and sends the schemes to the robot, and then the schemes are executed by the robot, so that intelligent material loading and unloading by the robot is finally realized.

Description

technical field [0001] The invention relates to a loading and unloading robot, in particular to a visual robot for loading and unloading a CNC lathe. Its outstanding feature is that the loading and unloading of the CNC lathe can be realized by using the monocular vision system. Background technique [0002] The application of China's vision technology began in the 1990s, because the industry itself is an emerging field, coupled with the lack of popularization of machine vision product technology, resulting in almost blank applications in the above industries. In the 21st century, a large number of overseas technicians engaged in the visual industry returned to China to start businesses, and visual technology began to be maturely applied in the automation industry. In 2004, Shenzhen Chuangke launched the first high-performance machine vision software development in China with epoch-making significance in the domestic visual industry. The package CKVision represents that the ...
