The invention discloses an automatic pressing-in device for a wire pressing-in terminal. The automatic pressing-in device comprises a terminal moving device, a terminal positioning device moving on the terminal moving device, a centre device fixed to the terminal moving device, a wire pressing-in device, a wire input device arranged beside the wire pressing-in device, and a CCD camera shooting device arranged beside the wire input device, wherein the wire pressing-in device is perpendicular to the terminal moving device and corresponds to the centre device in position. According to the automatic pressing-in device, a set of full-automatic actions of a plurality of wire inserting terminals are achieved by arranging the terminal moving device, the terminal positioning device, the wire input device and the wire pressing-in device. The coordinate positions of all holes in the terminal are obtained by arranging the CCD camera shooting device, and accurate position coordinates are provided for subsequent automatic wire inserting. The centre device is arranged at the corresponding position of the wire pressing-in device, an induction centre is inserted in the terminal from the back portion of the terminal, and it is guaranteed that after a wire is inserted in the terminal from the front portion of the terminal, the flatness of the end face of the terminal meets the requirement.
