Dual-purpose part identification method and device, and production line using the same

Abstract

The invention provides a dual-purpose part identification method and device and a production line using the same. Part information is pre-stored; two images of the part at the same position are captured through a binocular camera; the part type and the posture of the part actually in a production line are identified according to identification points on the image; calculation is carried out according to the obtained part posture to obtain an actual position and posture of a to-be-processed position of the part so as to bring convenience for a control unit to adjust the angle of a manipulator picking the part; under the premise of ensuring the production quality, the labor capacity of workers is reduced, and the investment in the production line is reduced.

Description

Technical field [0001] The invention belongs to the field of visual recognition, and in particular relates to a visual grasping device and a recognition method thereof. Background technique [0002] In car body production, it is often necessary to weld some sheet metal parts. Now the sheet metal parts are usually placed on the conveyor belt, and the nuts are welded to the predetermined positions on the sheet metal through the nut conveyor. However, in actual production, in order to make the nuts The installation is accurate. It is necessary to classify the sheet metal parts according to the shape, and then place them on the conveying equipment according to a certain angle. After reaching the designated station, the nut is welded to the predetermined position by the manipulator. However, this increases the workload of the workers. Moreover, due to the difference in the shape of the sheet metal parts during the nut welding process, multiple production lines are often required to pr...

[0002] In car body production, it is often necessary to perform nut welding on some sheet metal parts. Now the sheet metal parts are usually placed on the conveyor belt, and the nuts are welded to the predetermined position on the sheet metal through the nut conveyor. However, in actual production, in order to make the nuts For accurate installation, it is necessary to classify the sheet metal parts according to the shape, and then place them on the conveying equipment according to a certain angle. After arriving at the designated station, the manipulator will weld the nuts to the predetermined position, but this will increase the workload of the workers. And in the nut welding process, due to the shape difference of the sheet metal parts, multiple production lines are often required to produce separately, which increases the production investment
