Seam vision sensor with autofocus, iris adjustment and lens switching

Abstract

The invention discloses a welding seam vision sensor capable of automatic focusing, adjusting the aperture and switching lenses, which is composed of an image acquisition device, an aperture adjustment device, a focusing device and a lens switching device, the image acquisition device includes a lens and a camera, and the lens has an aperture The adjustment ring and the focus adjustment ring, the camera is located directly behind the lens, the aperture adjustment device includes a first ring clamp mounted on the aperture adjustment ring and a first drive motor that drives the first ring clamp to rotate, and the focus device includes a The second ring clamp on the focus adjustment ring and the second driving motor that drives the second ring clamp to rotate. The lens switching device includes a lens switching wheel and a third driving motor that drives the lens switching wheel to rotate. On the lens switching wheel There are multiple lenses evenly arranged along the circumference, and the lens switching wheel is turned to make any lens on the same line as the central axis of the lens and camera; the advantage is that operators with high operating skills are not required, the operation error is small, the speed is fast and stable.

Description

technical field [0001] The invention relates to a visual welding seam tracking system, in particular to a welding seam vision sensor capable of automatic focusing, adjusting aperture and switching lenses.
