The invention discloses a workpiece conveying, stacking and storing device comprising a workpiece conveying unit, a gasket conveying unit, a rotational lifting unit and a rotational storage frame. Therotational lifting unit is fixedly installed on the operation ground. The workpiece conveying unit and the gasket conveying unit are arranged on the front side and the back side of the rotational lifting unit. The rotational storage frame is arranged beside the rotational lifting unit and fixedly installed on the operation ground. According to the workpiece conveying, stacking and storing device,the workpiece conveying unit and the gasket conveying unit which are located on the front side and the back side of the rotational lifting unit feed workpieces and gaskets correspondingly, multiple mechanical arms of the rotational lifting unit grab the workpieces and the gaskets correspondingly and alternately place the workpieces and the gaskets in the rotational storage frame, and then stacking and storing of the workpieces are achieved; and since material loading racks can be detached from the rotational storage frame, fetching and placing are convenient, and the flexibility is improved.
