The invention relates to a workpiece anodic oxidization treatment process. The workpiece anodic oxidization treatment process includes the steps that a workpiece is assembled on a hanging tool, the hanging tool is connected with a walking device, and according to the type of the workpiece, a label device is arranged on the hanging tool or the walking device; a hanging type conveying line performsrunning, when an A1 recognizing device detects that the hanging tool runs to an A1 rack piece corresponding to the A1 recognizing device, an A1 driving mechanism adjusts the corresponding A1 rack piece to be located at a work position, the hanging tool is adjusted to descend till the workpiece on the hanging tool is immersed into tank liquid of an oxidizing tank, and after the hanging tool descends in place, the A1 driving mechanism adjusts the A1 rack piece to restore to an avoiding position; the hanging tool continues to walk in the oxidizing tank, when an A2 recognizing device detects thatthe hanging tool runs to an A2 rack piece corresponding to the A2 recognizing device, an A2 driving mechanism adjusts the corresponding A2 rack piece to be located at the work position, the hanging tool is adjusted to ascend till the workpiece on the hanging tool is completely taken out of the tank liquid of the oxidizing tank, and after the hanging tool ascends in place, the A2 driving mechanismadjusts the A2 rack piece to restore to the avoiding position; and anodic oxidization treatment of the workpiece ends.
