[0002] Currently, in order to improve the strength of aluminum profiles, the extruded aluminum profiles need to be subjected to anodic oxidation surface treatment.

[0003] In related technologies, the anodic oxidation surface treatment process generally includes the following steps: loading, pretreatment, anodic oxidation, and unloading; that is, first tying the aluminum profiles to the conductive frame, then moving the conductive frame to the cleaning tank for cleaning, and after cleaning, the aluminum profiles follow the conductive frame and move to the anodic oxidation tank. In the electrolyte solution in the anodic oxidation tank, electrolysis is used to form an aluminum oxide film on the surface of the aluminum profiles, and the anodized aluminum profiles can be removed from the conductive frame.

[0004] Regarding the above related technologies, the inventor believes that when installing the aluminum profiles on the conductive frame, generally, the form of manually tying steel bars is used to fix the aluminum profiles on the conductive frame, which is time-consuming and laborious.
