A turnover mechanism is configured to receive and flip over parts delivered by an in-feed conveyor to an out-feed conveyor. The turnover mechanism includes a frame and a gripper assembly coupled to the frame. The gripper assembly is configured to secure and move a part having one surface treated from the in-feed conveyor. The turnover mechanism further includes a flipper assembly coupled to the frame, the flipper assembly being configured to rotate and deliver the part to the out-feed conveyor with an opposite surface of the part exposed for treatment.
