When the aluminum workpiece mounted on the workpiece holder 36 on the hanger 34 is immersed in the anodizing treatment liquid in the anodizing container 10, the power is turned on, and the anode current flows through the conductive rod 54, the connecting rod 342, and the workpiece in sequence from the anode plate. The frame 36 and the aluminum workpiece are returned to the cathode plate 56 by anodizing treatment liquid as a conductor, so that the aluminum workpiece immersed in the anodizing treatment liquid is anodized. During the movement of the conveyor belt 22 from the end of the anodizing vessel 10 near the driving wheel 24 toward one end of the driven wheel 26, the conductive rod 54 fixed to each of the hangers 34 is also brought close to the driving wheel by the anodizing container 10.

In this embodiment, the closest linear distance between the aluminum workpiece and the cathode plate 56 is about 5-7 cm. When the distance is less than 5-7 cm, the anodized film on the aluminum workpiece grows too fast and the surface of the anodized film is rough, which will affect the appearance of the product; in addition, the thickness of the anodized film formed on the aluminum workpiece varies greatly. . When the distance is more than 5-7 cm, the number of aluminum workpieces which are simultaneously anodized is reduced, thus reducing the production efficiency.

When the anodizing apparatus 10 is applied, the rack 34 on which the workpiece rack 36 is hung is first mounted on a set of fixing seats 32 above the loading area 60, and is fixed on the workpiece rack 36 to be processed. The aluminum workpiece is immersed in the anodizing treatment liquid in the anodizing vessel 10; the power source is turned on, the cathode plate 56 is negatively charged, and the anode plate 52 is positively charged between the surface of the aluminum workpiece and the cathode plate 56. Forming an electric field to achieve anodizing treatment of the surface of the aluminum workpiece; meanwhile, the electronic control device controls the electronic control device 40 to drive the transmission device to move toward one end of the driven wheel 26 from one end of the driving wheel 24, After the aluminum workpiece on the hanger 34 above the blanking zone 60 is anodized, the hanger 34 can be hoisted together with the workpiece holder 36 to the next station by means of a crane (not shown) or the like. An anodizing cycle. When one of the sets of holders 32 is returned to the loading area 60 again after the blanking, another hanger 34 on which the workpiece holder 36 is hung is mounted on the set of holders 32, thus starting another anodizing cycle. .

It can be understood that when the number of sets of the fixing bases 32 is greater than 2, the previous set of the fixing brackets 32 provided with the hangers 34 can be moved to the other group of the loading areas 60 after leaving the loading area 60. Another holder 34 on which the workpiece holder 36 is attached is mounted on the holder 32 to be anodized as the actuator travels in the anodizing vessel 10.
