Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy surface processing, and in particular to a device for complex processing of aluminum alloy surfaces. Background Art

[0002] Aluminum alloy surface etching is a processing technology that uses chemical or electrochemical methods to corrode the surface of aluminum alloy to form a certain pattern or text on its surface. This processing method is often used to make various nameplates, decorative parts and functional parts. The main steps of aluminum alloy surface etching are as follows: Cleaning: First, the surface of the aluminum alloy needs to be cleaned to remove impurities such as oil, dust and other impurities on the surface to ensure the stability and uniformity of the etching effect. Coating: A layer of anti-etching coating is applied to the cleaned aluminum alloy surface. This coating is usually made of special chemicals and can protect the aluminum alloy surface from excessive corrosion during the etching process. Etching: The coated aluminum alloy is placed in the etching machine and corroded by chemical or electrochemical methods. Chemical etching uses the reaction between the corrosive liquid and the surface of the aluminum alloy to remove the coating, while electrochemical etching uses the action of electric current to cause an oxidation-reduction reaction on the surface of the aluminum alloy to achieve corrosion. Removal of coating: After etching, the anti-etching coating needs to be removed from the surface of the aluminum alloy to reveal the corroded pattern or text. Post-processing: Post-processing such as cleaning, polishing, oxidation, etc. is carried out as needed to improve the aesthetics and durability of the aluminum alloy surface.

[0003] At present, in the process of etching aluminum alloy, the etching liquid and protective coating on the surface of the aluminum alloy after etching need to be removed, and then the residual rinsing liquid on the surface of the aluminum alloy needs to be cleaned before subsequent processing can be carried out. At present, when removing the etching liquid, the rinsing liquid is generally used for direct flushing.

[0018] Compared with the prior art, the present invention provides a device for complex processing of aluminum alloy surface, which has the following beneficial effects:

[0019] 1. The device for complex surface processing of aluminum alloys can make the magnetic plate intermittently rotate to the position of the magnetic rod through the rotation of the cleaning roller, and the cleaning shaft rotates synchronously while the cleaning roller rotates, so that the etching liquid and protective coating remaining on the surface of the aluminum alloy can be removed and polished.
