[0002] At present, automobile bumper laser engraving equipment is widely used in the field of modern automobile manufacturing. Its core function is to perform fine laser engraving on the surface of the bumper, so as to replace multiple molds to process the bumper molding process. With the growth of consumers' demand for personalized automobile appearance and the improvement of industrial automation level, efficient laser engraving processing has gradually become one of the important means to optimize product quality.

[0003] At present, during the laser engraving process of the bumper, a fixed mechanical fixture is used to constrain the bumper to maintain a stable state so as to facilitate the smooth implementation of the laser engraving operation. However, in the face of large-scale continuous production scenarios, due to the inevitable slight deviations in the initial placement stage and the lack of effective compatibility considerations, most existing machines are unable to flexibly cope with bumper parts of various specifications and sizes. On the one hand, once the position misalignment occurs, it will directly affect the final image quality and cause the scrap rate to increase; on the other hand, when switching to different types of product models, the entire system needs to be reconfigured, which consumes a lot of time and energy in the debugging process and seriously affects the overall benefit output ratio.
