[0007] Furthermore, it includes a transverse driving part corresponding to the vertical guide plate channel, and the transverse driving part can drive the vertical guide plate channel to move transversely, so that the transversely moving vertical guide plate channel synchronously drags the right-angle plate workpiece on the workpiece support table to move transversely.

[0008] Furthermore, it includes a lifting drive part corresponding to the vertical guide plate channel, and the lifting drive part can drive the vertical guide plate channel to rise and fall; when the right-angle plate workpiece is laterally moved to a state where the center of gravity is offset to the outside of the workpiece support platform, the lifting drive part drives the vertical guide plate channel to rise and separate from the right-angle plate workpiece, and the right-angle plate workpiece is flipped over from the workpiece support platform to realize unloading, and a guide slope is provided on the flipping and unloading side of the right-angle plate workpiece.

[0010] Beneficial effect: The utility model realizes vertical positioning of the edges of the two plates by feeding the vertical plate first and then the horizontal plate, and the positioning is realized at the end position of the feeding. The workpiece support platform, the horizontal guide plate channel, the vertical guide plate channel and the pushing piece of the horizontal guide plate channel jointly participate in the positioning, and there is no need to set up a positioning mechanism as in the prior art. It not only saves costs, but also can increase the positioning speed of parts, thereby further improving the efficiency of fillet welding operations as a whole. BRIEF DESCRIPTION OF THE DRAWINGS
