Description

Technical Field

[0001] This utility model relates to a uniform coating device for nano-magnetic cores, belonging to the technical field of coating device technology. Background Technology

[0002] The uniform coating apparatus for nanoscale magnetic cores is a device specifically designed for coating the surface of nanoscale magnetic cores. The design and operating principle of this apparatus are crucial for ensuring the uniformity and performance of the coating. The uniformity of the coating directly affects the performance of the nanoscale magnetic cores in electromagnetic applications, such as in devices like high-frequency transformers, inductors, and magnetic sensors.

[0003] Chinese Patent Publication No. (CN 218108191 U) discloses a nanocrystalline magnetic core epoxy powder combined spraying device, including a fluidized bed. A ventilated base plate is fixedly installed at the bottom of the fluidized bed, and the ventilated base plate has uniformly distributed through holes inside. A motor bracket is fixedly installed on the side of the fluidized bed, and a motor is fixedly installed on the top of the motor bracket. A transmission shaft is fixedly installed on the output shaft of the motor, and the transmission shaft movably passes through and extends into the interior of the fluidized bed. This invention involves placing a magnetic core into the fluidized bed powder inside an immersion tank. Depending on the size of the magnetic core, the magnetic core is preheated to 200-250℃. Then, the magnetic core is immersed in the fluidized bed powder and rotated for 4-5 seconds. After two consecutive electrostatic spraying processes, the coating thickness of the inner and outer diameters is basically consistent, improving the uniformity of the coating thickness.

[0004] However, in order to ensure the performance of the magnetic core during use, the surface of the magnetic core needs to be coated during processing. However, the existing coating equipment can only process a single magnetic core and cannot process multiple magnetic cores at the same time, resulting in low processing efficiency and inconvenience for operators.

[0005] To address this, a device for uniformly coating nano-magnetic cores is proposed. Utility Model Content

[0015] I. This utility model uses a lifting mechanism to place the required magnetic core inside the placement frame.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-3 As shown, this utility model embodiment provides a uniform coating device for nano-magnetic cores, including a processing table 1, a storage tank 2 movably connected to the top of the processing table 1, a lifting mechanism 3 provided on the rear side of the processing table 1, the lifting mechanism 3 including a connecting plate 301, a telescopic cylinder 302, a connecting rod 303 and a placement frame 304, the front side of the connecting plate 301 is fixedly connected to the rear side of the processing table 1, the bottom of the telescopic cylinder 302 is fixedly connected to the top of the connecting plate 301, the bottom of the connecting rod 303 is fixedly connected to the output end of the telescopic cylinder 302, the rear side of the placement frame 304 is fixedly connected to the front side of the connecting rod 303, a sliding groove 4 is provided on the front side of the processing table 1, the connecting rod 303 is movably connected to the inside of the sliding groove 4, filter holes 5 are provided on the surface of the placement frame 304, the filter holes 5 are evenly distributed on the surface of the placement frame 304, a limiting block 6 is fixedly connected to the top of the processing table 1, and the left and right sides of the storage tank 2 are movably connected to the inside of the limiting block 6.

[0029] The lifting mechanism 3 is used to place the required magnetic core inside the placement frame 304. The telescopic cylinder 302 is then activated, which moves the connecting rod 303. The connecting rod 303 moves the placement frame 304 downward, so that the placement frame 304 moves into the storage tank 2. A coating is then applied to the surface of the magnetic core. By setting the filter holes 5, excess coating can be separated back into the storage tank 2, ensuring uniform coating of the magnetic core.

[0030] Example 2

[0031] like Figure 3-5As shown, in one embodiment, a cavity 7 is provided on the front side of the storage tank 2. A positioning mechanism 8 is provided inside the cavity 7. The positioning mechanism 8 includes a moving rod 801, a positioning rod 802, and a tension spring 803. The front side of the moving rod 801 extends through the cavity 7 to the front side of the storage tank 2, and the rear side of the moving rod 801 extends through the cavity 7. The top of the positioning rod 802 is fixedly connected to the bottom of the moving rod 801. A tension spring 803 is sleeved on the surface of the positioning rod 802. The top of the tension spring 803 is fixedly connected to the bottom of the positioning rod 802, and the bottom of the tension spring 803 is fixedly connected to the inside of the cavity 7. The bottom of the positioning rod 802 extends through the inside of the processing table 1. A fixing groove 9 is provided on the top of the processing table 1. The bottom of the positioning rod 802 is movably connected to the inside of the fixing groove 9. A limiting groove 10 is provided inside the cavity 7. A limiting rod 11 is fixedly connected to the rear side of the positioning rod 802, and the rear side of the limiting rod 11 is movably connected to the inside of the limiting groove 10.

[0032] When coating different magnetic core materials, the original storage tank 2 needs to be disassembled and cleaned by using the positioning mechanism 8. Pulling the moving rod 801 upward will cause the positioning rod 802 to move upward, making it convenient for workers to disassemble the storage tank 2. By setting the limiting groove 10, the moving direction and stroke of the positioning rod 802 can be restricted when it moves, ensuring the normal use of the overall structure.

[0033] In operation, this invention works as follows: First, the magnetic core to be coated is placed inside the placement frame 304. Then, the telescopic cylinder 302 is activated, which moves the connecting rod 303 downward. The connecting rod 303 moves the placement frame 304 downward, allowing the placement frame 304 to move into the storage tank 2. The coating is then applied to the surface of the magnetic core. After completion, the placement frame 304 is raised to separate the excess coating into the storage tank 2. When different magnetic cores need to be coated, the raw material inside the storage tank 2 needs to be replaced. The moving rod 801 is pulled upward, which moves the positioning rod 802 upward, allowing the positioning rod 802 to move along the movement trajectory provided by the limit groove 10. This facilitates the disassembly and cleaning of the storage tank 2 by the staff.
