And then an industrial computer 3 sends out instructions to control a plurality of upper rail shuttle trolleys 2-2 to move on the longitudinal guide rails 2-4, so that the distances between the upper rail shuttle trolleys are equal, and the distance between the two rail shuttle trolleys 2-2 which are farthest away is ensured to be 4/5 of the width of the steel plate. The plane equation of the lower surface of the steel plate (i.e. the surface in contact with the electromagnet) is calculated by the industrial computer 3 according to the angle requirements required for welding the steel plate. And then the coordinates of the positions of the hydraulic cylinders are brought into a plane equation to obtain the height values of the electromagnets, and the expansion and contraction of the hydraulic cylinders 1-3 are regulated so that the centers of the plurality of electromagnets 1-1 reach the designated height values. The steel plate is hung to the upper part of the welding position changing jig frame by using a crane, and the electromagnet is controlled by the industrial computer 3 to start the adsorption steel plate.
