A fine butt weld detection system with binocular, dual-path convergent and adjustable optical path

Abstract

The invention discloses a fine butt weld detection system with a binocular, two-way convergent and adjustable optical path, comprising: an image controller, a first imaging device and a second imaging device respectively connected to the image controller, and the first imaging device And the second imaging device is arranged on both sides of the image controller, a first light source generating device is provided on one side of the first imaging device, a second light source generating device is provided on one side of the second imaging device, and the first The imaging device is rotated by an angle α to the vertical direction, the second imaging device is rotated by an angle β to the vertical direction, the first light source generating device is rotated by an angle γ to the vertical direction, and the second light source generating device is rotated by an angle δ to the vertical direction. The detection system can not only increase the light intensity and make the light intensity uniform, but also eliminate the gap feature extraction error caused by the shadow produced by the single light source; by adjusting the inclination angle of the two light sources on both sides to change the incident angle of the light, the welding at different positions can be realized. seam detection.

Description

technical field [0001] The invention relates to the field of weld seam detection, in particular to a fine butt weld seam detection system with binoculars, two paths, converging and adjustable optical paths. Background technique [0002] Today, with the rapid development of the processing and manufacturing industry, the precision automatic welding technology of fine butt welds is more and more widely used. This kind of fine butt weld usually does not have a groove, the weld gap is within 0~1mm, and the amount of weld misalignment or misalignment is within 0~1mm. When welding such welds, a slight position deviation of the workpiece positioning system or welding system will cause welding defects, affect production and reduce efficiency. This requires the use of sophisticated weld inspection equipment to detect welds in real time. However, the features of such welds are not obvious, and it is difficult to extract weld features using conventional visual inspection methods, and ...
