Problems solved by technology

However, since this system cannot realize the remote multi-information wireless monitoring of the welding process, and at the same time, there is a problem that the dynamic information of the molten pool cannot be obtained in real time, and thus the online adjustment of the welding parameters and the real-time control of the welding quality cannot be realized.

Embodiment

[0038] like figure 1 As shown, a multi-information acquisition and monitoring system for a robot welding process includes:

[0039] The robot control cabinet 1 is used to send walking and welding instructions to the robot 9, and send the real-time pose information of the robot welding torch and the welding arc start signal to the main control computer 6;

[0040] The welding visual sensing unit 2 is used for real-time acquisition of molten pool images in the dynamic process of robot welding. The arc light is projected onto the CCD photosensitive chip of the visual sensing system through the dimming filter of the dimming filter system of the welding arc. The photosensitive chip is converted into an electrical signal through photoelectric conversion, and the electrical signal is converted into an image signal through signal processing. The image of the molten pool collected by the system is clear, and the edge of the molten pool is relatively easy to extract;

The multi-information acquisition monitoring system in the robot welding process is suitable for multiple types of welding robots and welding power supplies and can achieve wireless network remote monitoring and real-time controlling on a large-scale multi-robot welding and manufacturing production line, then the manufacturing and welding quality and the production efficiency are improved, and the great technologicalprogress significance is achieved.

Description

technical field [0001] The invention relates to an industrial robot monitoring system, in particular to a multi-information collection monitoring system and method for a robot welding process. Background technique [0002] The industrial robot is equipped with a welding torch at the end shaft, and at the same time, a variety of sensing perceptions such as vision sensors, current and voltage sensors are added to the welding system. Using robots to replace humans in welding work can liberate welding workers from harsh working environments. And stable and efficient welding operation, improve welding quality and reduce production costs. Therefore, robotic welding related technologies are widely used in mechanical processing, shipbuilding, electronic production and other fields. At present, the supervision and management of production lines by welding manufacturing enterprises at home and abroad are mainly limited to the level of on-site workshop control. Many robot welding stat...
