Description

Technical Field

[0001] The present invention relates to the technical field of workpiece grinding equipment, and more particularly to a workpiece grinding device based on a 3D vision camera. Background Art

[0002] The biggest difference between a 3D vision camera and a traditional 2D camera that can only obtain planar images is that it can obtain depth of field data. By combining the plane coordinates (X, Y) and the depth data Z of the camera from that point, the three-dimensional coordinates of each point in the image can be obtained, thereby completing tasks such as restoring and reconstructing real scenes.

[0003] The distance measurement method generally uses structured light, that is, a beam of invisible infrared light of a specific wavelength is used as a light source to illuminate the object. The object's position and depth information are then obtained based on the returned optically distorted image, thereby completing the distance measurement. This distance measurement method can be combined with traditional workpiece grinding devices. Because traditional workpiece grinding devices cannot determine the spacing between adjacent workpieces during grinding, they cannot adaptively adjust the relative positions of the grinding components, thereby failing to speed up the workpiece grinding rate.

[0004] Secondly, during the grinding process, traditional workpiece grinding devices generate debris that can splash and easily damage the skin of surrounding workers. The pollution generated by the debris is also difficult to clean, that is, the environmental performance of traditional workpiece grinding devices is poor.

[0005] Therefore, in order to solve the above problems, it is necessary to provide a workpiece grinding device based on a 3D vision camera. Summary of the Invention
