Numerical control welding method, numerical control welding device and numerical control welding system

Abstract

The invention discloses a numerical control welding method, a numerical control welding device and a numerical control welding system. The numerical control welding method includes: collecting video images of preset welding positions in advance and sharpening edges to acquire sharpening images of the preset welding positions; focusing a camera to a welding joint on a welding gun, collecting video images containing the welding joint and the current welding positions every time when the camera is adjusted to capture new position, and sharpening edges to acquire sharpening images containing the welding joint and the current welding positions; judging whether the sharpening images containing the welding joint and the current welding positions are matched with the sharpening images of the preset welding positions or not, and if yes, locking the welding joint of the welding gun at the current welding position; and scanning the welding joints of the locked welding positions to acquire video images when welding, filtering to acquire welding tracks, and controlling a numerical control drive device to adjust position and rotating angle of the welding joint of the current welding gun to follow the welding tracks to weld. Welding point positions are positioned accurately, welding tracking is accurate, and efficient automatic welding is realized.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to a numerical control welding method, device and system. Background technique [0002] In the current welding of equipment structures, most of them are still manually operated, so that the labor intensity of workers is high, the labor protection is poor, and the welding work is performed manually, and the welding efficiency is relatively low. However, the traditional CNC automatic welding (including robotic equipment) widely used at present, due to the non-standard tooling, the position of the CNC positioning welding spot is not accurate, the welding seam tracking is not accurate, the scrap rate is high, and a large number of manual participation is required , the production efficiency is low, and the efficiency of automation equipment cannot be brought into play. [0003] Therefore, how to locate the position of the welding spot and complete the welding problem with high efficien...
