The present invention having the above-described configuration has the following effects.
First, the laser beam is irradiated to the surface of the plate, which is the workpiece to be transferred, to quickly find and correct the upper and lower bent portions, which are nonuniform flatness, to maintain the flatness within the tolerance range.
Secondly, there is also an effect of preventing defective products by accurately and promptly locating and correcting the position where the flatness of the plate as the workpiece is defective.
Third, there is an effect that the worker is not exposed to the dangerous environment and accordingly, the problem of the safety accident is prevented in advance.
