Therefore, workpieces to be fed need to be placed in the stock bin which is located on the same horizontal plane with the material pushing cylinder in advance, and the fed workpieces need to be attached to the horizontal plane and pushed by the material pushing cylinder to complete feeding. When some small-sized sheet-shaped workpieces need to be vertically sucked from the material tray, the horizontal feeding mechanism disclosed above cannot complete the material taking action, and the horizontal feeding mechanism cannot carry out translation conveying on the materials carried and sucked.
