Aluminum material anodic oxidation dyeing device

Abstract

The invention discloses an aluminum material anodic oxidation dyeing device, and belongs to the technical field of aluminum material anodic oxidation dyeing. The aluminum material anodic oxidation dyeing device comprises a working pool, a first guide rail, a second guide rail horizontally moving along the first guide rail and a carrying piece arranged on the second guide rail, wherein the second guide rail can move along the first guide rail to change the horizontal position of the carrying piece; the carrying piece can move up and down along the second guide rail and can carry a workpiece, so that the workpiece can enter or leave the working pool; the aluminum material anodic oxidation dyeing device further comprises a working piece and a spraying unit, the working piece is provided with a working cavity communicated with the outside, a workpiece can enter the working cavity, the spraying unit can spray the workpiece entering the working pool from the working cavity, and the working cavity can receive liquid sprayed on the workpiece by the spraying unit. By the adoption of the structure, the amount of acid liquid attached to the workpiece and entering working pools such as the dyeing pool can be effectively reduced, and the dyeing effect of the workpiece is prevented from being affected.

Description

technical field [0001] The application belongs to the technical field of anodic oxidation dyeing of aluminum materials, and specifically provides an anodic oxidation dyeing device of aluminum materials. Background technique [0002] The anodic oxidation dyeing process of aluminum can be divided into anodic oxidation stage and dyeing stage. The anodic oxidation of aluminum or aluminum alloy is an electrochemical process that uses the anode reaction in the electrolyte to form an aluminum oxide film. The anodic oxidation of aluminum or aluminum alloy can effectively improve the surface hardness, wear resistance, Corrosion resistance, insulation and dyeing properties have been widely used in daily necessities, handicrafts, machinery manufacturing and other fields. Anodizing methods include sulfuric acid method, oxalic acid method, chromic acid method and titanium potassium oxalate method, etc. The sulfuric acid method is a common method for anodizing aluminum or aluminum alloy....

AI Technical Summary

Problems solved by technology

Anodizing methods include sulfuric acid method, oxalic acid method, chromic acid method and titanium potassium oxalate method, etc. The sulfuric acid method is a common method for anodizing aluminum or aluminum alloy. In the electrolyte, a lead plate is commonly used as a cathode to form an oxide film on the surface of the aluminum or aluminum alloy, and then the aluminum or aluminum alloy is separated from the electrolyte, and the aluminum or aluminum alloy is immersed in a washing pool for washing, and then the aluminum or aluminum alloy is washed. The alloy is dyed, and the washing process after anodizing and before dyeing is very important. Since the acidic liquid attached to the aluminum or aluminum alloy is brought into the dyeing pool, the pH value of the dyeing solution in the dyeing pool will drop, and the pH value of the dyeing solution will drop. It will cause the color tone of the product to be colored to change and affect the production quality

During the handling of aluminum or aluminum alloy workpieces, since aluminum or aluminum alloy workpieces are mostly suspended on conductive beams, during the handling process, aluminum or aluminum alloy workpieces are prone to shaking, so there are particles attached to aluminum or aluminum alloy workpieces. The possibility of the acidic liquid dripping into the dyeing pool, thereby affecting the pH value of the dyeing pool; and the acidic liquid will enter the dyeing pool with the aluminum or aluminum alloy workpiece, affecting the pH value of the dyeing liquid, thereby affecting the dyeing effect on the workpiece

Due to the limitations of the processing environment and other factors, impurities such as dust are easy to adhere to the workpiece, and problems such as blisters are easy to occur during the process of anodic oxidation to form an oxide film, which affects the film quality of the formed oxide film.
