The invention belongs to the technical field of laser marking, and particularly relates to complicated special-shaped multi-position laser marking equipment. The complicated special-shaped multi-position laser marking equipment comprises a base. The base is provided with a control main machine, an optical fiber marking machine main machine and a stand column. The complicated special-shaped multi-position laser marking equipment is characterized in that the base is further provided with a translation mechanism, the upper end of the translation mechanism is connected with a climbing mechanism, the upper end of the climbing mechanism is connected with an installing seat, the upper end of the installing seat is provided with a three-dimensional working platform, and the operation platform surface of the three-dimensional working platform is provided with a workpiece fixing mechanism. The invention further relates to a complicated special-shaped multi-position laser marking method, the method includes the following steps of loading of workpiece, detecting, positioning, marking, unloading and the like. The complicated special-shaped multi-position laser marking equipment has the advantages that the range of product marking is enlarged, the efficiency of the product marking is improved, meanwhile, the demands of complicated special-shaped marking are met, and the application range of the laser marking equipment is enlarged.
