Frame is loaded in aluminum plate oxidation includes: the framework, set up in positive pole electric conductor and negative pole electric conductor in the framework, be provided with the electric contact of interval arrangement on positive pole electric conductor and the negative pole electric conductor respectively, set up in negative plate in the framework, the negative plate with electric contact on the negative pole electric conductor contacts, set up in anode plate in the framework, the anode plate with electric contact on the positive pole electric conductor contacts, the anode plate with the negative plate is parallel, the negative plate with the anode plate in turn the interval set up in in the framework. The utility model discloses can load many aluminum plate simultaneously, every aluminum plate two sides all has the great negative pole of area neat right for the electric field radiation that aluminum surface can obtain is abundant, and aluminum surface current density distributes evenly, and it is high to have improved production efficiency, and oxide film thickness distribution is even.
