The lifting cylinder 350 drives the gripper body 380 to descend, thus gripping the workpiece and moving it to the straightening position for straightening. After straightening, qualified workpieces are moved to the qualified storage mechanism 400 by the longitudinal moving robot 300. The swing cylinder 360 drives the gripper fixing plate 370 to rotate the gripper body 380 horizontally, thus rotating the workpiece horizontally and placing it into the qualified storage mechanism 400, completing the unloading process of qualified workpieces. Unqualified workpieces are directly moved to the rejection storage mechanism 500 by the longitudinal moving robot 300, completing the unloading process of unqualified workpieces.
