The camera positioning assembly 60 is coupled to the coaxial assembly 20 via a first optically transmissive end.

In practical use, laser emitted by the laser 10 is transmitted to the galvanometer lens 30 through the coaxial component 20, reflected to the field lens 40 through the galvanometer lens 30, and then focused on the workpiece 80 to be processed through the field lens 40, so as to facilitate laser processing. Meanwhile, the illumination light on the workpiece 80 to be processed can be reflected to the field lens 40, reflected to the galvanometer lens 30 through the field lens 40, transmitted to the coaxial assembly 20 under the reflection action of the galvanometer lens 30, transmitted to the camera positioning assembly 60 through the first light-transmitting end of the coaxial assembly 20, and imaged on the camera positioning assembly 60.

Meanwhile, large-range marking is realized by matching the coaxial assembly 20 with the field lens 40. Moreover, the light path transmitted to the camera positioning component 60 needs to pass through the coaxial component 20 to eliminate the problems of image distortion, offset and blurring, so that large-range marking, positioning and code reading operations of coaxial positioning are realized, the processing precision is improved, the time consumption of laser processing is shortened, the processing efficiency is improved, and the market demand is further met.

Meanwhile, the camera positioning assembly 60 uses a CCD (charge coupled device) camera for imaging.
