Specific embodiments

[0024] The following specific embodiments illustrate the embodiments of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] With reference to Figures 1 - 6, the utility model provides a processing device for the permanent magnet coating of a magnetic levitation pump rotor, which includes an immersion plating solution tank 1 and a suspension 2 fixedly connected to the top of the immersion plating solution tank 1. A Teflon solution can be placed in the immersion plating solution tank 1. A telescopic mechanism 3 is arranged on the immersion plating solution tank 1, and a plurality of loading components 4 are longitudinally stacked on the telescopic mechanism 3. Each loading component 4 includes an annular plate 41, a leakage plate 42 fixedly connected inside the annular plate 41, and a plurality of leakage cylinders 43 fixedly connected to the leakage plate 42. In this application, the size of the leakage cylinder 43 is smaller than the size of the hollow structure inside the rotor, so as to ensure that the immersion plating solution entering the annular plate 41 can fully contact the rotor. The leakage plate 42 and the leakage cylinders 43 are used to place the hollow magnetic levitation pump rotor, because the magnetic levitation pump rotor is a hollow annular structure.

[0026] A hollow shaft tube 5 is fixedly penetrated through the suspension 2. The inside of the hollow shaft tube 5 can be used for gas circulation. One end of the hollow shaft tube 5 is fixedly connected to a rotating pressing plate 6. The rotating pressing plate 6 is movably inserted into the annular plate 41 at the top. A jetting frame 7 is fixedly connected to the bottom of the rotating pressing plate 6. The jetting frames 7 are annularly distributed at the bottom of the rotating pressing plate 6. The jetting frames 7 can evenly distribute and release the drying source entering the hollow shaft tube 5. The jetting frames 7 are communicated with the hollow shaft tube 5. The other end of the hollow shaft tube 5 is rotatably connected to an air inlet pipe 51. The air inlet pipe 51 can be externally connected to a fan device or an air pump device. A rotary drive mechanism 8 for driving the hollow shaft tube 5 to rotate is arranged on the suspension 2.

[0027] The telescopic mechanism 3 includes a telescopic device 31 fixedly connected to the bottom of the immersion plating solution tank 1 and a hollow tray 32 rotatably connected to the output end of the telescopic device 31. The hollow tray 32 is located inside the immersion plating solution tank 1. The telescopic device 31 can adopt a telescopic motor, and the connection between the telescopic motor and the immersion plating solution tank 1 should be sealed. The hollow tray 32 and the output end of the telescopic device 31 can be rotatably connected through a bearing.

[0028] Specifically, after placing a plurality of rotors at the connection of the leakage cylinders 43 and the leakage plate 42, and stacking a plurality of annular plates 41 on the hollow tray 32, at this time, the telescopic device 31 can control the hollow tray 32 to descend, so that the annular plate 41 can be immersed in the immersion plating solution tank 1. By using the hollow structures of the hollow tray 32, the leakage cylinders 43 and the leakage plate 42, the immersion plating solution in the immersion plating solution tank 1 can be plated on the magnetic levitation pump rotor.

[0029] A plurality of positioning columns 9 are fixedly connected to the top of the annular plate 41. A slot 10 adapted to be inserted with the positioning column 9 is arranged at the bottom of the annular plate 41. The positioning column 9 and the slot 10 are inserted and matched. When stacking two adjacent annular plates 41, the two annular plates 41 can be inserted through the corresponding positioning column 9 and slot 10, so that a plurality of annular plates 41 can achieve the effect of limited stacking.

[0030] An auxiliary insertion rod 12 that cooperates with the insertion slot 10 is fixedly connected to the hollow tray 32. A positioning slot for inserting the positioning post 9 is provided at the bottom of the rotating pressing plate 6. The provision of the auxiliary insertion rod 12 on the hollow tray 32 enables the annular plate 41 to be placed on the auxiliary insertion rod 12 to achieve the effect of insertion limit, so as to prevent the material-carrying assembly 4 from shifting.

[0031] A handle rod 11 is fixedly connected to the peripheral side of the annular plate 41, and the handle rod 11 can facilitate the lifting of the annular plate 41.

[0032] A rotary joint 13 is provided at the relative ends of the hollow shaft tube 5 and the air inlet pipe 51. The air inlet pipe 51 is fixedly installed on the suspension 2. A heater 14 is provided on the air inlet pipe 51. The hollow shaft tube 5 can be hermetically and rotatably connected to the air inlet pipe 51 through the rotary joint 13. When the air inlet pipe 51 is pressurized and fed with air source by an external air pump device or a fan device, the heater 14 can heat the air source to quickly dry the immersed rotor and at the same time remove the excess coating.

[0033] The rotary drive mechanism 8 includes a rotary device 81 fixedly connected to the suspension 2, a first gear 82 fixedly connected to the output end of the rotary device 81, and a second gear 83 meshingly connected to the first gear 82. The second gear 83 is fixedly connected to the outer surface of the hollow shaft tube 5. In this application, the rotary device 81 can adopt a rotary motor, and both the rotary device 81 and the telescopic device 31 are controlled and driven by a controller.

[0034] Specifically, when the material-carrying assembly 4 on the hollow tray 32 is immersed in the immersion plating solution tank 1 to complete the immersion plating of the rotor, at this time, the hollow tray 32 can rise and drive the annular plate 41 located at the top to be inserted and corresponding to the rotating pressing plate 6. Utilizing the rotatability of the hollow tray 32 on the telescopic device 31, the rotary device 81 is controlled to start. It can drive the first gear 82 to meshingly drive the second gear 83, and then the hollow shaft tube 5 can drive the rotating pressing plate 6 to rotate. The rotation of the rotating pressing plate 6 enables the multiple stacked material-carrying assemblies 4 to rotate, so as to perform centrifugal rotation processing on the magnetic levitation pump rotor, which can effectively remove the excess coating on the rotor. At the same time, an external air source can be fed into the end of the air inlet pipe 51, and the air source can be heated by the heater 14. The heated air source is evenly released and distributed downward through the air jet frame 7. In this way, the rotor in the material-carrying assembly 4 can be dried, ensuring that the rotor coating is uniform and has no dripping points, while being convenient for quick drying. Therefore, the efficiency and quality of the magnetic levitation pump rotor coating processing can be improved.
