[0029] When the customized shelf is welded at its bottom, the flip frame 2 is controlled to flip as a whole, which can drive the side frame 3, the clamping part 4 and the customized shelf to flip as a whole. At this time, the hydraulic oil is sent into the double-axis hydraulic cylinder 5 by the pressure provided by the electric hydraulic pump, and the piston in the double-axis hydraulic cylinder 5 moves under the action of the liquid pressure, thereby driving the side frame 3 to move. The double-axis hydraulic cylinder 5 controls the side frame 3 to move back and forth on the flip frame 2 as a whole, driving the shelf to translate, so as to avoid the flip frame 2 covering the bottom of the shelf during flip welding, thereby ensuring smooth welding operation.
