[0038] After the shape of the H-shaped steel is fixed, the PLC control system controls the roller motor 43 to rotate, so that the H-shaped steel is transported from the roller structure 4 into the positioning structure 34 through the upper transport wheel 36 and the lower transport wheel 35 of the assembling machine 3. The wing plate will move in the positioning structure 34 through the wing plate positioning wheel 346, which can ensure that the wing plate moves in a fixed position.
