Weld joint identification device and identification method suitable for flat plate butt weld joint

Abstract

The invention discloses a welding seam recognition device and recognition method suitable for flat plate butt welding seams, the welding seam recognition device comprises a sliding device and an adjusting device, the end of the sliding device is provided with a driving device, the rear side face of the sliding device is provided with a fixing device, and the top of the sliding device is provided with a horizontal regulator and an industrial personal computer. A fixing device is arranged at the end of the adjusting device and used for fixing an industrial camera and a laser pen which are used for recognition. According to the recognition method, aiming at the limitation that segmentation of a current FCM clustering algorithm is easy to fall into local optimum, the FCM clustering algorithm is optimized by searching a clustering center in combination with a mucous flora intelligent algorithm, so that the image quality is obviously improved, and details and contours of an image edge region are clear. The method can be suitable for flat plates with different weld lengths and is high in adaptability; the field installation is rapid, the stability of device operation during identification is good, the identification method is high in identification speed, good in reliability and robustness and high in precision, and the welding seam identification efficiency of a construction site is greatly improved.

Description

technical field [0001] The invention relates to the technical field of welding seam identification, in particular to a welding seam identification device and an identification method suitable for flat butt welds. Background technique [0002] With the rapid development of modern manufacturing and the promotion of construction industrialization, people have higher and higher requirements for production efficiency and quality control in the welding process. The traditional welding method makes the welding quality highly dependent on the technical proficiency of the workers, while the construction quality is poor. The introduction of welding robots has realized the intelligentization of welding technology, the automation of welding process, improved welding efficiency, and improved the working environment. Robot automated welding process based on visual sensing has become the future development trend of the industry. [0003] The most important factor affecting the quality of ...
