Abstract

The invention provides a method for scanning a weld seam of a corrugated plate. The corrugated plate is located on a base, and a weld seam is formed between the corrugated plate and the base, comprising the following steps: scanning on the surface of the corrugated plate to obtain multiple position points; The multiple position points obtained by scanning are drawn into a weld locus diagram; the first N position points of a position point in the weld locus diagram are fitted to the first straight line, and the last N position points are fitted to the second straight line. The angle between the first straight line and the second straight line is recorded as the first corner angle of the position point, and N is greater than or equal to 1; repeat the above steps to obtain the first corner angle of all position points; the first corner angle of each position point Comparing an inflection angle with a preset angle, multiple inflection points are obtained; a scanning trajectory is made on the base near the weld, and a welding plane is fitted according to the scanning trajectory; the welding seam position is obtained by calculating the inflection point and the welding plane. Only two scans are required to determine the position of the weld seam, which improves the efficiency of weld seam calculation and reduces the cost of weld seam scanning.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding seam scanning method for a corrugated plate. Background technique [0002] Corrugated plate welding is widely seen in industrial production, and automatic seam location is a key technology to greatly improve production efficiency and reduce labor and time costs. At present, the common automatic positioning technology in industrial production is based on line laser or surface laser positioning. The main principle is to reconstruct the welding seam structure and identify the welding seam position through line laser or surface laser sensor. This kind of sensor can find the position in real time and is suitable for various types of welds, but at the same time, it is expensive and has limited operating space. Contents of the invention [0003] The object of the present invention is to provide a weld seam scanning method for a corrugated plate, which can reduce scanning c...
