Welding seam automatic identification anti-bending device

Abstract

The invention provides a welding seam automatic identification anti-bending device. The welding seam automatic identification anti-bending device comprises: at least one bending machine; a visual identification system; a conveying system; a grabbing robot; and a control system. After a steel plate sample is conveyed to a recognition area of the visual recognition system through the conveying system, the visual recognition system can recognize welding seams on the steel plate sample, and then the grabbing robot transfers the steel plate sample to the bending machine from the conveying system according to the recognition result of the visual recognition system; and finally, the steel plate sample is bent for multiple times by a bending machine, and it is judged whether the weld strength meets requirements according to whether the steel plate sample is broken. In the process, the recognition of the visual recognition system on the welding seam is not influenced by the shape of the steel plate sample, the position of the welding seam on the steel plate sample and other factors, so that the bending machine can bend by taking the welding seam as a reference, and the accuracy of a detection result is ensured.

Description

technical field [0001] The invention relates to the field of weld seam quality detection, in particular to an automatic weld seam identification and anti-bending device. Background technique [0002] When producing and processing steel coils, it is necessary to use laser welding or resistance welding to weld the tail of the previous coil and the head of the next coil together, and then continuously process through various process sections to achieve steel Continuous production of rolls. The quality of the weld seam directly affects whether the steel coil will break after receiving tension when passing through various process sections. Therefore, it is necessary to test the strength of the weld seam before the steel coil passes through various process sections. [0003] At present, the commonly used detection method is to use equipment such as disc shears to punch and shear the end of the welded part along the width direction of the steel coil after welding to obtain a steel...
