[0002] In the field of thin film electroplating equipment, electrophoretic coating of metal films is an important surface treatment process. Its purpose is to form a uniform and dense coating on the surface of the metal film to improve its corrosion resistance, wear resistance and decorative properties.

[0003] Currently, traditional metal film electrophoretic coating equipment has many shortcomings. Its main working component, the electrode rod, is fixed in the electrophoresis tank by bolts and other means. As the usage time increases, the electrode rod will wear out and need to be replaced. If foreign objects appear on the outside of the electrode rod, it needs to be removed and cleaned. This fixing method results in many disassembly and assembly steps when replacing the electrode rod, which is cumbersome. In addition, it is necessary to regularly check whether there are any problems with its appearance. When inspecting the electrode rod placed in the electrophoresis tank, it is also necessary to disassemble and remove it for inspection, which also leads to the problem of cumbersome inspection process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 4 This embodiment provides a high-efficiency electrophoretic coating device for metal films, including an electrophoresis tank 1. Two first guide rollers 2 are symmetrically and rotatably installed on the lower end of the inner wall of the electrophoresis tank 1, and two second guide rollers 3 are symmetrically and rotatably installed on the top surface of the electrophoresis tank 1. A lifting frame 4 is installed at the middle position of the top surface of the electrophoresis tank 1.

[0024] In this embodiment, a sliding rod 5 is fixed at each of the two opposite corners of the lifting frame 4. Both sliding rods 5 are slidably connected to the electrophoresis tank 1 through the first sliding hole. An electric push rod 6 is provided at the bottom of each of the other two opposite corners of the lifting frame 4. The electric push rod 6 is fixed on the outer wall of the electrophoresis tank 1. The protruding end of the electric push rod 6 is slidably connected to the electrophoresis tank 1 through the second sliding hole, and the protruding end of the electric push rod 6 is fixed to the lifting frame 4.

[0025] In this embodiment, by simultaneously extending the electric push rods 6, the lifting frame 4 can be pushed up; by simultaneously retracting the two electric push rods 6, the lifting frame 4 can be driven down.

[0026] In this embodiment, two sets of electrode rods 7 are symmetrically arranged in the middle of the electrophoresis tank 1. Each set of electrode rods 7 is arranged at equal intervals along the length of the electrophoresis tank 1. A sleeve 8 is fixed on the bottom surface of the lifting frame 4, directly opposite the electrode rod 7. An insert 9 is fixed on the top of the electrode rod 7 and is inserted into the inside of the sleeve 8.

[0027] In this embodiment, after fixing the insert 9 to the top of the electrode rod 7, the insert 9 is inserted into the sleeve 8. The outer wall of the insert 9 and the inner wall of the sleeve 8 have a certain frictional force, so that the insert 9 can be stably pre-limited in the sleeve 8 without applying a certain external force. After installing the electrode rod 7, the upper end of the electrode rod 7 is clamped by a power clamp or other structure to realize the power supply, and then electrophoresis can be realized.

[0028] In this embodiment, a U-shaped groove 10 is formed at one end of the insert 9 near the electrode rod 7. The upper end of the electrode rod 7 is located inside the U-shaped groove 10, and a disc protrusion is formed on the top of the electrode rod 7. Multiple bolts 11 are threadedly connected to the side wall of the opening of the U-shaped groove 10 through threaded holes. The ends of the bolts 11 abut against the outer wall of the electrode rod 7. The electrode rod 7 is surrounded in the U-shaped groove 10 by the multiple bolts 11, thus realizing the connection between the insert 9 and the electrode rod 7. When the electrode rod 7 is raised for inspection, the electrode rod 7 is rotated, and the electrode rod 7 and the insert 9 can rotate relative to each other, so that the electrode rod 7 can be rotated for inspection. Otherwise, the electrode rod 7 needs to be manually moved to inspect it.

[0029] In this embodiment, a pin 12 is slidably connected to the side wall of the sleeve 8 through a third sliding hole. A spring 13 is sleeved on the outside of the pin 12. One end of the spring 13 is fixed to the outer wall of the sleeve 8, and the other end of the spring 13 is fixed to the outer wall of the pin 12. A locking hole 14 is opened on the outer wall of the insert 9 opposite to the pin 12, and the end of the pin 12 is inserted into the locking hole 14.

[0030] In this embodiment, after inserting the insert 9, the pin 12 is released, and the spring 13 pulls the pin 12 into the slot 14 to complete the final positioning. In the positioned state, the end of the pin 12 away from the slot 14 abuts against the outer wall of the sleeve 8.

[0031] In this embodiment, a plurality of connecting rods 15 are fixed on the top surface of the electrophoresis tank 1. Each connecting rod 15 corresponds to a socket 8. A triangular plate 17 is fixed on one side of the upper end of the connecting rod 15. A drive rod 16 is fixed on the end of the pin 12 away from the card hole 14. Each drive rod 16 is located directly below a triangular plate 17 that is close to it. The drive rod 16 cooperates with the triangular plate 17.

[0032] In this embodiment, when electrode rod 7 needs to be disassembled, the electric push rod 6 extends, causing the lifting frame 4 to rise to a certain height. The drive rod 16 moves along the inclined surface of the triangular plate 17, and under the push of the triangular plate 17, the pin 12 moves away from the locking hole 14 and is pulled out of the locking hole 14 until the pin 12 unlocks and the electric push rod 6 stops extending. At this time, the insert 9 unlocks. After removing the insert 9, the electric push rod 6 is replaced or cleaned and reinstalled. The drive electric push rod 6 retracts, the lifting frame 4 descends, and then locks again. When electrode rod 7 needs to be inspected, the drive electric push rod 6 extends fully, causing the lifting frame 4 to rise to its highest position. Electrode rod 7 is removed from the electrophoresis tank 1. At this time, since the drive rod 16 leaves the triangular plate 17, the pin 12 is still in the locked state of electrode rod 7. The electrode rod 7 can be directly inspected by rotating it. After the inspection is completed, the lifting frame 4 descends to its lowest position again, the electrode rod 7 resets, and the drive rod 16 passes through the triangular plate 17 again, and the pin 12 is still in the locked position.

[0033] In summary, the installation of electrode rod 7 on the lifting frame 4 makes it easier for people to inspect electrode rod 7. The electrode rod 7 is detachably installed on the lifting frame 4 through the structure of the sleeve 8 and the insert 9, which greatly reduces the operation steps when assembling and disassembling electrode rod 7, making it more convenient and efficient to use.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
