The automatic folding and stacking method for washed wrinkled abdominal pads comprises the following steps: The washed wrinkled abdominal pad material is stacked on a storage plate. An operator approaches the station and sequentially feeds the material onto the conveyor belt, securing the four corners of the pad with positioning pins. A motor operates intermittently, utilizing the characteristics of a servo motor, causing the material to sequentially enter the gripping station. Automatic folding occurs, folding the material twice more until it is fully folded. A second servo robot operates, moving a pusher plate laterally to move the folded pad for unloading. The robot then moves back to its initial position, completing one cycle of folding and stacking. Repeating steps one through five allows for continuous folding and stacking of washed wrinkled abdominal pad material. This invention features high intelligence, enabling automatic and rapid folding and stacking of washed wrinkled abdominal pads, significantly reducing manpower consumption and greatly improving processing efficiency.
