The invention relates to a full-automatic chemiluminescence immunity analyzer, which consists of a reaction cup feeding system, a three-dimensional mobile sample adding module, a sample area, a reagent area, a pump set and a control system. The reaction cup feeding system comprises a stacking module, a transfer module, an incubation module, a washing module and a measuring chamber, wherein the stacking module is positioned at the leftmost end; reaction cup transfer passages of the modules are positioned on the same height; the reaction cup location exit of the incubation module can be alignedwith the transfer groove outlet of the transfer module and the transfer groove inlet of the washing module; the transfer passage exits of the rest modules are aligned; and the three-dimensional mobile sample adding module is positioned above the rest modules. When the system works, a three-dimensional mobile arm automatically distributes sample solution and reagent solution to a reaction cup, thereaction cup sequentially passes through the modules of the transfer system, and operations of incubation, washing, detection and the like are completed. The analyzer has compact and reasonable structure, high automation degree and quick and accurate detection, and is suitable to be used in various hospitals.
