A full-automatic chemiluminescence immunity analyzer comprises a frame, a transferring system, a sampling system, an incubation system, a cleaning system, an optical detection system and a control system. The transferring system comprises a cup feeding mechanism, a cup inlet and a grasping mechanism; the sampling system comprises a sample tray, a reagent tray, a sample adding mechanism and two first driving sources; the incubation system comprises an incubation tray, a second driving source and a mixing mechanism; the cleaning system comprises a cleaning plate and a third driving source; the optical detection system comprises photometric plate and an optical collection mechanism. When sample analysis is required, the full-automatic chemiluminescence immunity analyzer is started and controlled to operate by the control system, and then the transferring system, the sampling system, the incubation system, the cleaning system and the optical detection system operate correspondingly, so that all operations are automatic operations. The full-automatic chemiluminescence immunity analyzer has advantages that probabilistic problems including individual differences, manual errors, operational nonuniformity and the like of manual operations are avoided effectively, and accuracy in chemiluminescence immunity analysis is improved.
