Tiny butt weld detection system of binocular two-way convergence adjustable optical path

Abstract

The invention discloses a tiny butt weld detection system of a binocular two-way convergence adjustable optical path, comprising an image controller, and a first imaging device and a second imaging device which are connected with the image controller. The first imaging device and the second imaging device are arranged at the two sides of the image controller. A first light source generation device is arranged at one side of the first imaging device, and a second light source generation device is arranged at one side of the second imaging device. The first imaging device rotates an angle of alpha relative to the vertical direction, the second imaging device rotates an angle of beta relative to the vertical direction, the first light source generation device rotates an angle of gamma relative to the vertical direction, and the second light source generation device rotates an angle of delta relative to the vertical direction. By adopting the detection system, the light intensity can be increased and made uniform, and gap feature extraction error caused by shadow produced by lighting of a single light source can be eliminated. By adjusting the inclination angles of two light sources at the two sides, the incident angle of light can be changed, and welds in different positions can be detected.

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, an...
