Description

Technical Field

[0001] This utility model relates to the field of zirconium coating treatment technology for electrophoretic parts, and specifically to a zirconium coating treatment device for electrophoretic parts. Background Technology

[0002] In the production and processing of electrophoretic parts, zirconium coating is a crucial process. Zirconium coating can form a uniform, dense film with good corrosion resistance and adhesion on the surface of the electrophoretic parts, thereby significantly improving the performance and service life of the parts and enabling them to better adapt to various complex operating environments. However, electrolytes, additives, and other impurities may remain on the surface of the electroplated workpieces. Therefore, thorough cleaning is necessary to remove these residues. Existing zirconium coating equipment for electrophoretic parts lacks systematicity and coordination in its overall design. The fit between various components is not tight enough, resulting in a low degree of automation in the entire process. It requires a lot of manual intervention and operation, which is not only prone to human error but also difficult to meet the needs of high-efficiency production. Furthermore, a fixture needs to be designed to hold the workpiece before coating, making the operation cumbersome. Utility Model Content

[0027] like Figures 1 to 5As shown, this utility model provides a zirconium coating treatment device for electrophoretic parts, including a cleaning tank 1 and a zirconium coating tank 2. A crossbeam 4 is arranged above the cleaning tank 1 and the zirconium coating tank 2. The crossbeam 4 is stably supported by brackets 3 on both sides. A movable electric hoist 5 is installed on the crossbeam 4. The movable electric hoist 5 is precisely controlled by a PLC controller and can realize automated operation according to a preset program. It can move horizontally along the crossbeam 4. A positioning tube 8 is fixedly installed at the bottom of the movable electric hoist 5. The side wall of the positioning tube 8 has a sandwich layer. A telescopic tube 801 is arranged in the sandwich layer. The shrink tube 801 passes through and extends to the lower part of the positioning tube 8. A telescopic spring 802 is also provided in the side wall interlayer of the positioning tube 8. A limit ring 803 is fixedly installed at the bottom end of the telescopic spring 802. One end of the telescopic tube 801 located in the side wall interlayer of the positioning tube 8 is fixedly connected to the bottom of the limit ring 803. A steel wire rope 804 is provided on the mobile electric hoist 5. The steel wire rope 804 passes through the positioning tube 8 and the telescopic tube 801 and extends to the lower part of the telescopic tube 801. The lower end of the steel wire rope 804 is connected to the placement frame 11 through the connecting steel rope 10. The placement frame 11 is used to place the electrophoresis components.

[0028] When zirconium coating treatment is required on the electrophoretic parts, the electrophoretic parts are first placed in the placement frame 11. Then, the placement frame 11 is moved above the zirconium coating tank 2 by the mobile electric hoist 5. Anode columns 21 are fixedly installed on both sides of the zirconium coating tank 2. The first cathode plate 22 is fixedly installed on the bottom inner wall of the zirconium coating tank 2. Power-carrying wires are connected to the anode columns 21 and the first cathode plate 22. An installation hole is opened in the middle of the bottom of the placement frame 11, and a second cathode plate 1102 is installed in the installation hole. The mobile electric hoist 5 slowly lowers the placement frame 11. The second cathode plate 1102 is placed into the zirconium plating bath 2, and then comes into contact with the first cathode plate 22 in the zirconium plating bath 2. Electricity is applied, and at the same time, the zirconium plating solution in the zirconium plating bath 2 comes into contact with it. After the power is turned on, an electric field is formed between the anode column 21 and the first cathode plate 22 and the second cathode plate 1102, so that zirconium ions in the plating solution are deposited on the surface of the electrophoretic part to form a zirconium plating film. After the plating is completed, the mobile electric hoist 5 removes the placement frame 11 from the zirconium plating bath 2. Finally, the waste liquid can be discharged through the drain pipe on one side of the zirconium plating bath 2.

[0029] When it is necessary to clean the electrophoretic parts that have completed zirconium coating, the mobile electric hoist 5 can be controlled by the PLC controller, and the placement frame 11 can be moved above the cleaning tank 1 via the wire rope 804 and the connecting steel rope 10.

[0030] Specifically, in this embodiment, a mounting plate 7 is fixedly installed on the upper part of the mobile electric hoist 5. Connecting hoses 9 are fixedly installed on both sides of the bottom surface of the mounting plate 7. A cavity is opened inside the mounting plate 7. The top ends of the connecting hoses 9 extend into the cavity opened in the mounting plate 7. A water pipe sleeve 701 is installed on the right side of the mounting plate 7. A fixing plate 6 is installed on the right side of the water pipe sleeve 701. A connecting water pipe 602 is installed on the side of the fixing plate 6 on the back. A water outlet 601 is installed at one end of the connecting water pipe 602, which penetrates and extends to the outside of the left side of the fixing plate 6. The water outlet 601 can be inserted into the water pipe sleeve 701. A sealing ring is provided inside the water pipe sleeve 701 to prevent water leakage when the water outlet 601 supplies water to the cavity inside the mounting plate 7 through the water pipe sleeve 701. The connecting water pipe 602 can be connected to an external water pipe through a water pump. When the water pump is turned on, the cleaning fluid can flow into the cavity opened in the mounting plate 7 and into the connecting hose 9.

[0031] More specifically, in this embodiment, a plurality of water inlet pipes 1101 are installed on the outer surface of the placement frame 11. The plurality of water inlet pipes 1101 are interconnected. A plurality of cleaning spray heads 1103 extending into the interior of the placement frame 11 are installed on the water inlet pipes 1101. The bottom end of the connecting hose 9 is connected to the top of the water inlet pipes 1101 installed in the middle of both sides of the placement frame 11. The placement frame 11 and the water inlet pipes 1101, cleaning spray heads 1103 and connecting hose 9 installed on the placement frame 11 are all made of non-conductive material, such as plastic. The cleaning liquid can enter the water inlet pipes 1101 through the connecting hose 9 and finally spray out from the cleaning spray heads 1103 to clean the electrophoresis components in the placement frame 11. The wastewater from the cleaning will fall into the cleaning tank 1.

[0032] Preferably, in this embodiment, the placement frame 11 has first flow holes on both sides of the second cathode plate 1102, and several second flow holes are provided on the four sides of the placement frame 11. When the placement frame 11 is located in the zirconium coating tank 2, the first and second flow holes allow the zirconium coating solution to enter the placement frame 11, so that the electrophoretic part comes into contact with the zirconium coating solution. When the placement frame 11 is located in the cleaning tank 1, the first and second flow holes allow the cleaning solution sprayed by the cleaning nozzle 1103 to flow into the cleaning tank 1. After cleaning, the wastewater can be discharged through the drain pipe on one side of the cleaning tank 1.

[0033] Preferably, in this embodiment, the wire rope 804 is fixedly installed with a pressing plate 805 on the lower outer ring of the telescopic tube 801. The top surface of the pressing plate 805 is in close contact with the bottom surface of the telescopic tube 801. When the mobile electric hoist 5 drives the placement frame 11 to move upward through the wire rope 804 and the connecting steel rope 10, the pressing plate 805 will also move upward and can press the bottom of the telescopic tube 801, so that the upper part of the telescopic tube 801 can move into the interlayer of the side wall of the positioning tube 8, which can prevent the rotation phenomenon when the placement frame 11 moves upward.

[0034] Working principle and usage process of this utility model:

[0035] In use, the electrophoretic zirconium coating treatment device first places the electrophoretic parts into the placement frame 11. At this time, the electrophoretic parts in the placement frame 11 are in contact with the second cathode plate 1102 at the bottom of the placement frame 11. Then, the PLC controller controls the mobile electric hoist 5 to move the placement frame 11 above the zirconium coating tank 2. The placement frame 11 is then placed into the zirconium coating tank 2 by driving the steel wire rope 804 and connecting steel rope 10. At this time, the anode column 21 and the first cathode plate 22 can be connected to the power supply. After the placement frame 11 is placed into the zirconium coating bath 2, the second cathode plate 1102 at the bottom of the placement frame 11 comes into contact with the first cathode plate 22 and can be energized. At the same time, it also comes into contact with the zirconium coating solution in the zirconium coating bath 2. An electric field is formed between the anode column 21, the first cathode plate 22 and the second cathode plate 1102, so that zirconium ions in the coating solution are deposited on the surface of the electrophoretic workpiece to form a zirconium coating. This achieves the purpose of zirconium coating on the workpiece in the placement frame 11, avoiding the problem of clamping the workpiece during the traditional workpiece coating process.

[0036] When it is necessary to clean the electrophoretic parts that have completed zirconium coating, the mobile electric hoist 5 can be controlled by the PLC controller, and then the placement frame 11 can be moved to the top of the cleaning tank 1 via the wire rope 804 and the connecting steel rope 10. The connecting water pipe 602 can be connected to the external water pipe through the water pump. The water outlet 601 is inserted into the water pipe sleeve 701, and water can flow into the cavity opened in the mounting plate 7 and into the connecting hose 9. Then, it enters the water inlet pipe 1101 through the connecting hose 9, and finally sprays out from the cleaning spray head 1103 to clean the electrophoretic parts in the placement frame 11.

[0037] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model.
