DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] As Figure 1-2 shown, a micro - arc oxidation production line includes an input production line, an output production line, and a micro - arc oxidation station. The conveying terminal of the input production line is the micro - arc oxidation station, and the conveying starting end of the output production line is the micro - arc oxidation station. The micro - arc oxidation station is provided with a number of micro - arc oxidation tanks. The micro - arc oxidation tank 8 is provided with a number of compartments with openings upward. The interiors of all the compartments located in the same micro - arc oxidation tank 8 are in communication with the interior of the micro - arc oxidation tank 8. The compartments are made of insulating materials. A window 9 is provided on one side wall of the compartment. Products loaded by hanging tools facing the window 9 can be placed inside the compartment. A cathode plate 10 is provided in the micro - arc oxidation tank 8 outside the compartment opposite the window 9.

[0017] In this embodiment, during operation, electrolyte is placed in the micro-arc oxidation tank 8. Then, the worker places the workpiece (the product to be micro-arc oxidation) in the input production line through a hanger. The input production line conveys the hanger carrying the workpiece into the micro-arc oxidation tank 8. The electrolyte in the micro-arc oxidation tank 8 submerges the workpiece and the cathode plate 10, and at the same time makes the workpiece face the window 9, thus avoiding the edge effect of micro-arc oxidation. Furthermore, after the workpiece is micro-arc oxidized, there will be no phenomenon of uneven film thickness and the color of the edge being darker than that in the middle, thereby solving the problem of the edge effect. At the same time, the cathode plate 10 only requires a relatively small area. Compared with the traditional method of setting a large cathode plate 10 corresponding to many workpieces, the area of the cathode plate is reduced, and electric energy is saved.

[0018] As a preferred method, a pre-washing station is provided between the micro-arc oxidation tank 8 and the starting end of the input production line on the input production line, and a post-washing station is provided between the micro-arc oxidation tank 8 and the conveying terminal of the output production line on the output production line. The workpiece is conveyed by the production line to the pre-washing station for cleaning. The pre-washing station cleans the impurities on the surface of the workpiece that has not been micro-arc oxidized, facilitating the micro-arc oxidation of the workpiece in the micro-arc oxidation tank. The post-washing station is used to clean the electrolyte on the surface of the workpiece after micro-arc oxidation.

[0019] As a preferred method, in practical applications, the speed of cleaning the workpiece at the pre-washing station and the post-washing station is several times the speed of micro-arc oxidation, and the speed of cleaning the workpiece at the pre-washing station and the post-washing station is equal. In practical applications, when multiple micro-arc oxidation tanks can be accommodated between a pre-washing station and a post-washing station, the production efficiency reaches the maximum.

[0020] As a preferred method, multiple micro-arc oxidation tanks 8 can be accommodated between the input production line and the output production line, which can maximize the production efficiency of the entire production line. However, due to the limited area of the workshop, three micro-arc oxidation tanks 8 are set in the micro-arc oxidation station.

[0021] As a preferred method, the pre-washing station includes a first washing station 2 and a second washing station 3. The input production line is also provided with a pre-treatment station 1 (including degreasing, etc.). The input production line is sequentially provided with a pre-treatment station 1 (including degreasing, etc.), a first washing station 2, and a second washing station 3 from the starting end to the terminal. After such a setting, the oil stains on the workpiece are cleaned by the pre-treatment station 1, and then the large impurities on the workpiece are cleaned by the first washing station 2. The second washing station is a fine washing, that is, it is used to clean the workpiece again after being cleaned by the first washing station 2, so that the impurities on the workpiece are completely cleaned.

[0022] As a preferred method, the post-washing station includes a third washing station 4 and a fourth washing station 5. The output production line is further provided with a post-treatment station 6 and a drying station 7. The third washing station 4, the fourth washing station 5, the post-treatment station 6, and the drying station 7 are sequentially arranged between the starting end and the terminal end of the output production line. In this way, the workpiece after micro-arc oxidation is cleaned by the third washing station 4 and the fourth washing station 5 to clean the electrolyte on the workpiece after micro-arc oxidation. Then, the post-treatment station 6 is used for surface treatment after maintenance oxidation, and the drying station 7 dries the workpiece.

[0023] As a preferred method, the compartments are arranged in one or more straight-line formations in the micro-arc oxidation tank 8, and the cathode plates 10 are also arranged in one or more straight-line formations in the micro-arc oxidation tank 8. One row of the compartments is correspondingly arranged on one side of the formation formed by the arrangement of the cathode plates 10. Such a design can make one side of one row of cathode plates 10 correspond to one row of compartments. One row of cathode plates 10 is arranged between two rows of hangers, so that the front of one cathode plate 10 corresponds to the window 9 of one compartment on one row of hangers, and the back corresponds to the window 9 of one compartment on the other row of hangers. This can reduce the setting of the cathode plates 10, save space, and save the number of cathode plates 10, thereby saving costs.

[0024] Preferably, a liquid inlet pipe 18 and a liquid outlet pipe 19 are provided in the micro-arc oxidation tank 8. The electrolyte is input into the micro-arc oxidation tank 8 through the liquid inlet pipe 18, and at the same time, the electrolyte after micro-arc oxidation in the micro-arc oxidation tank 8 is output through the liquid outlet pipe 19, so as to control the temperature and conductivity of the electrolyte in the micro-arc oxidation tank 8 and keep the electrolyte in the micro-arc oxidation tank 8 evenly mixed.

[0025] As a preferred method, a plurality of U-shaped insulating plates 20 are provided in each micro-arc oxidation tank 8. The projection of the U-shaped insulating plate 20 on the inner bottom wall of the micro-arc oxidation tank 8 is U-shaped. The U-shaped open ends of the U-shaped insulating plates 20 located in the same micro-arc oxidation tank 8 are fixedly connected to the same inner side wall of the micro-arc oxidation tank 8. A preset gap is provided between the lower end of the U-shaped insulating plate 20 and the bottom wall of the micro-arc oxidation tank 8. The window 9 is provided on the U-shaped closed end of the U-shaped insulating plate 20. Such a setting method is convenient for setting compartments in the micro-arc oxidation tank 8. At the same time, it also makes any compartment communicate with the inside of the micro-arc oxidation tank 8, so as to facilitate the flow of the electrolyte in the same micro-arc oxidation tank 8 and the electrolyte in the compartment.
