[0049] First, according to the input preset length of the first workpiece 1, the first clamping drive cylinder 93 drives and adjusts the position of the first clamping portion 4 to prepare for the position adjustment before welding of the first workpiece 1 and the third workpiece 3.

Finally, driven by the third leveling cylinder 723, the detection plane of the detection disk assembly 71 contacts the flat surface of the first workpiece 1 to detect the flatness of the flat surface.

[0053] If the flatness test of the flat surface of the first workpiece 1 fails, the first clamping portion 4 is driven to loosen to replace the first workpiece 1; the replaced first workpiece 1 continues to be tested for the flatness of its corresponding flat surface. After the flatness test of the flat surface of the first workpiece 1 passes, the flatness driving device 72 drives the flatness testing device 7 to return to its original position.

[0054] At this time, the third clamping drive cylinder 95 drives the third supporting platform 61 to move the third workpiece 3 to the position of the first workpiece 1 for welding preparation; at the same time, the first clamping drive cylinder 93 drives the supporting plate 9 to move the first workpiece 1 to the position of the second workpiece 2 for welding preparation.
