Plain butt weld detection system based on dual-path converged adjustable light path

Abstract

The invention relates to a plain butt weld detection system based on a dual-path converged adjustable light path. The plain butt weld detection system comprises an imaging device and an image controller, wherein the image controller is connected with the imaging device; two light source generation devices are symmetrically arranged on both sides of the imaging device, can rotate at a certain angle with a vertical direction; light rays emitted from the light source generation devices pass through a detected plate to enter the imaging device, the imaging device transmits an image to the image controller, and the image controller processes the received image to obtain a high-definition weld detection image. The detection system disclosed by the invention realizes the detection illumination of a plain butt weld by utilizing the dual-path converged light path, thereby enhancing the illumination intensity and eliminating the influence of a shadow generated through a single-path light irradiation weld on the detection of a weld position; the light path is changed by adjusting the angles of the light sources and the adjustment of the optimal incident angle of the light path before convergence can be realized, so that the weld illumination of different positions can be realized and an clearly imaged weld image is obtained.

Description

technical field [0001] The invention relates to the field of weld seam detection, in particular to a non-groove butt weld seam detection system based on a two-way converging and adjustable optical path. Background technique [0002] In the field of welding automation, automatic welding of thin plate welds such as aluminum plates and stainless steel plates is often required. Such welds usually do not have grooves, and the weld gap is zero gap or small gap (within 0~1mm). And the requirements for the real-time performance, precision and reliability of weld detection are relatively high (the detection time is within 0.05s, and the detection accuracy is within 0.05mm). It is difficult to realize real-time, effective, reliable and high-precision detection due to the small characteristics of the weld seam itself, which is easily affected by interference by using conventional line structured light welding seam inspection, which affects the development of automatic welding technolog...
