Optical welding seam tracking systems

What Is Laser Weld Tracking Sensor

The automatic weld tracking sensor mainly consists of a CCD camera, a semiconductor laser, a laser protection lens, a splash-proof baffle, and a wind cooling device. By using the principle of triangulation, the coordinate information of each point in the laser scanning area is obtained, and the online real-time detection of common welding seams is realized through complex program algorithms, and the robot is guided to adjust the working trajectory according to the scanning data.

Working Principle

The laser seam tracking sensor uses a laser to irradiate the surface of the weld seam to form a laser light band, which is received and imaged by a high-definition camera. By algorithmic processing, the three-dimensional features of the weld seam are transformed into structured information, including welding joint coordinates, misalignment, gaps, etc. This information is transmitted to the robot controller, providing the robot with the required trajectory and process parameters for welding, guiding the robot to weld or correct workpiece deviations in real-time, and achieving perfect welding work. Compared to other solutions, laser seam tracking has the advantages of non-contact, high accuracy, fast speed, and good adaptability.
