[0002] A beam laser emitter consists of multiple groups of laser emitter components and a mounting stand. When assembling a beam laser emitter, multiple groups of different laser emitter components need to be installed on the mounting stand at different orientations and angles, and the installation accuracy of each group of laser emitter components needs to be controlled at 0.1 mm. The laser emitter components are large in size, heavy in weight, and have high installation accuracy. At present, the assembly of a beam laser emitter usually uses cranes, forklifts and other engineering machinery and equipment to lift and assemble each laser emitter component. Since laser emitter components of different specifications or sizes need to be assembled on the mounting stand at different spatial positions and angles, a variety of engineering machinery and equipment are often required to assist in the assembly process. The assembly process is restricted by factors such as equipment accuracy and human operation. Therefore, the assembly process of the beam laser emitter needs to ensure the docking accuracy by repeatedly adjusting the docking position of each laser emitter component. The overall installation and debugging process is relatively complicated, the operation is not convenient, and the efficiency is not high. Summary of the invention
