Welded combination visual sensor device

Abstract

The invention discloses a welded combination visual sensor device which comprises a base, a line laser sensor, a line laser sliding-out mechanism, a CCD camera module and a CCD sliding-out mechanism. The line laser sensor is installed on the base through the line laser sliding-out mechanism. The line laser sensor can slide out of the base to enter the working position through the line laser sliding-out mechanism. The CCD camera module is installed on the base through the CCD sliding-out mechanism. The CCD camera module slides out of the base to enter the working position through the CCD sliding-out mechanism. The welded combination visual sensor device can achieve the two functions of measuring grooves of plates of the moderate thickness and observing a welding pool and has the beneficial effects of being good in universality, convenient to adjust, capable of memorizing the position, good in protective effect and the like, and therefore the welded combination visual sensor device has the good research value and feasibility.

Description

technical field [0001] The invention relates to a visual sensor device, in particular to a visual sensor device for medium and thick plate welding. Background technique [0002] According to the thickness of the welded workpiece, the weldment can be divided into thin plate, medium plate and thick plate. In general, thin plates refer to weldments with a thickness of ≦4.5mm, medium plates refer to weldments with a thickness between 4.5 and 20mm, and thick plates refer to workpieces with a thickness greater than 20mm. Medium plate and thick plate are collectively referred to as medium and heavy plate. [0003] Line laser sensor is a common tool to realize the groove measurement of medium and thick plate weldment. The current traditional method is to fix the line laser sensor on the welding robot to measure the groove before welding, and then remove the line laser after the measurement is completed, so as to avoid damage to the line laser sensor caused by thermal radiation or ...

AI Technical Summary

Problems solved by technology

The patented laser ranging sensor is to assist the CCD camera in visual positioning, and cannot achieve groove measurement

[0007] To sum up, none of the existing technologies can realize the two functions of groove measurement and weld pool observation of medium and heavy plate workpieces at the same time, and none of them protects the sensing device.
