The invention discloses an automatic wafer carrying crown block which comprises a frame, a movement driving mechanism and a multi-stage grabbing mechanism. The frame comprises a top platform, a front vertical frame and a rear vertical frame. The front vertical frame and the rear vertical frame are located at the front end and the rear end of the lower side of the top platform respectively. The moving driving mechanism is arranged on the upper side of the top platform and used for driving the frame to walk along the rails. The multi-stage grabbing mechanism is arranged on the lower side of the top platform and located between the front vertical frame and the rear vertical frame, and the multi-stage grabbing mechanism is used for grabbing objects below in a telescopic and lifting mode. According to the scheme, the whole frame structure is optimized, the whole crown block is more balanced, a moving driving mechanism of the crown block is optimized, the running stability of the crown block is improved, meanwhile,
