Welding is a common connection method in modern manufacturing industry. However, due to deformation, defects and other problems in the welding process, it is difficult to maintain stable weld quality. In recent years, visual matching technology has been widely used in the field of welding, it realizes the precise control of welding position through image processing and recognition technology, so as to improve the quality and stability of welding. This paper will introduce the welding technology of vision matching and its application.
What is visual matching technology
Vision matching technology is a kind of technology that realizes image processing and recognition by using computer vision technology. By analyzing and processing the image, it can realize the automatic recognition and positioning of the target object, and realize the adaptive control through the feedback signal.
Second, the application of visual matching in welding
Visual matching technology is widely used in welding. Among them, the most important application is in improving the quality and stability of welding.
Positioning control: When welding, it is necessary to position the welding part to ensure the accuracy of welding. Traditional methods usually use clamps or manual adjustments to achieve positioning. However, this method has some problems such as low precision and long positioning time. The visual matching technology can realize the automatic identification and positioning of welding position by analyzing and processing the image of the welding surface, so as to improve the positioning accuracy and speed.
Defect detection: Traditional weld defect detection is often manual, inefficient and inaccurate. Visual matching technology can quickly detect defects in welds through image recognition and comparison, so as to improve detection efficiency and accuracy.
Attitude control: During the welding process, the welding gun needs to maintain a certain attitude to ensure the quality and stability of the welding. By analyzing and processing the image of the welding area, the vision matching technology can realize the adaptive control of the attitude of the welding torch, so as to ensure the quality and stability of the welding.
Third, the advantages of visual matching technology in welding
Compared with traditional welding methods, vision matching technology has the following advantages:
High precision: visual matching technology can realize accurate positioning and adaptive control of welding position and attitude by analyzing and processing the image of the weldment surface, thus improving welding accuracy and stability.
High speed: visual matching technology can realize automatic welding, avoiding the need for manual adjustment, detection and other links in traditional welding, thereby improving welding speed and efficiency.
Quality stability: visual matching technology can monitor and feedback the welding process in real time, find and correct welding quality problems in time, so as to ensure the quality stability of welding.
Iv. Summary
Vision matching technology is a very promising welding technology. It realizes image processing and recognition through computer vision technology, and realizes automatic control of welding position and attitude, thereby improving welding performance
