The invention discloses an etching station aluminum anode oxidation component regeneration preparation technology. The etching station aluminum anode oxidation component regeneration preparation technology comprises the following steps: step one, carrying out ungrease treatment on an aluminum component; step two, putting the aluminum component into an alkaline liquor for alkali corrosion; step three, putting the aluminum component into an acid liquor for ash removal; step four, washing; step five, carrying out anode oxidation on the aluminum component; step six, cleaning and drying; step seven, using a tri-cathode plasma spray gun to spray a sizing agent onto an anode oxidation layer of the aluminum component, uniformly controlling the thickness of a sprayed coating to be 60 to 150 microns; step eight, drying and cleaning; and step nine, drying, cooling and packaging. Compared with the prior art, sand blasting pretreatment does not need to be carried out on the component, the anode oxidation layer also does not need sealing treatment, the operation procedure is reduced, the cost is reduced, the productivity is improved, simultaneously, the loss and deformation caused by a sand blasting technology for the component are avoided, and the number of times of repeated regeneration for the component is increased.
