The laser welding seam tracking system mainly consists of a CCD camera, laser, welding seam tracking sensor, optical components, and central processing unit. By utilizing the principles of optical propagation and imaging, the position information of each point in the laser scanning area is obtained. Through complex programming algorithms, online real-time detection of common welding seams is completed. There are corresponding functional settings for the detection range, detection capability, and common problems encountered during the welding process. Sensors are usually installed at a pre-set distance (advance) in front of the welding gun, so it can observe the distance from the weld sensor body to the workpiece, that is, the installation height depends on the sensor model installed. Only when the welding gun is correctly positioned above the weld seam can the camera observe the weld seam. Let's take a look at the advantages of laser seam tracking system technology.
The laser welding seam tracking system uses sensors to perform online real-time detection of common welding seams through complex programming algorithms. There are corresponding functional settings for the detection range, detection capability, and common problems encountered during the welding process. The device calculates the deviation between the detected weld seam and the welding gun, outputs deviation data, and the motion execution mechanism corrects the deviation in real time, accurately guiding the welding gun to automatically weld, thereby achieving intelligent real-time tracking of the weld seam during the welding process.
