[0002] Patent No. CN201721812513.8 discloses a laser welding tracking device. By setting up an X-axis translation track, a Y-axis translation track, and a Z-axis translation track, the position adjustment of the laser welding head in the three-dimensional direction can be realized. By setting up a ranging sensor, the vertical distance between the laser welding head and the product to be welded is detected in real time, and the controller is adjusted in time to ensure the consistency of the vertical distance. By setting up an image collector, the image of the splicing gap of the product to be welded during the welding process is obtained in real time and the image is processed, compared, and analyzed with the image before welding. The deviation is adjusted in time by the controller to avoid the weld deviating from the splicing gap. The deviation is tracked and corrected in three dimensions, and the welding quality is greatly improved. However, the following component composed of the ranging sensor and the image collector is fixedly installed and cannot be rotated intelligently.
