The invention relates to the field of surface treatment of an automobile brake valve aluminum alloy die-casting valve body, in particular to a full-automatic passivation production line. The invention provides the full-automatic passivation production line. According to the full-automatic passivation production line, a walking truss 3 can move left and right along an H-shaped beam 1 under the control of a walking system 5; a lifting truss 4 can move up and down under the control of a lifting system 6; and because the lifting system 6 and the lifting truss 4 are arranged on the walking truss 3, and a control system 10 is connected to the walking system 5 and the lifting system 6, the control system 10 can control the lifting truss 4 to drive workpiece baskets hung on the lifting truss 4 to perform stepping motion on lower operation stations. The full-automatic passivation production line has the advantages that the structure is simple, the manufacturing cost is low, the control is precise, and the labor intensity of workers can be effectively reduced; and due to the fact that the whole production line is controlled through automation, the processing technology of products of all batches can be completely identical, and the quality of the produced products can be reliably guaranteed.
