Description

Technical Field

[0001] This utility model relates to the field of nanocrystal processing technology, specifically to a resin impregnation device for nanocrystals. Background Technology

[0002] Nanocrystalline ribbons are typically thin and soft. After processes such as winding and cutting, the resulting magnetic core structure may not be robust enough and is prone to deformation, loosening, or even damage during handling, installation, or use. By immersing nanocrystals in liquid resin, the resin fills the tiny pores and gaps inside the material. After curing, this enhances the overall mechanical strength and vibration and impact resistance of the structure.

[0003] When impregnating nanocrystalline magnetic cores, a vacuum impregnation tank is usually used. The pressure difference allows the resin to penetrate into the nanocrystalline core. However, the resin is usually placed in the impregnation tank, which has a large penetration resistance. This can easily lead to insufficient penetration in some areas and uneven penetration. In addition, the resin may contain dissolved or encapsulated air bubbles. In a static state, the air bubbles are difficult to escape, which affects the impregnation quality. Utility Model Content

[0014] (III) Beneficial Effects

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. The shear force generated by the stirring component and the circulation component make the resin flow, which can better overcome the penetration resistance and make the resin easier to enter the tiny pores and gaps. This ensures that the resin can evenly and fully contact all parts of the magnetic core, guaranteeing the uniformity of impregnation and improving the impregnation quality.

[0017] 2. The coordinated operation of the stirring and circulation components can break up and release the tiny bubbles dissolved in the resin. Combined with the vacuum treatment of the vacuum pump, it can more effectively eliminate bubbles and reduce defects caused by bubbles.

[0018] 3. The circulation component can pump the resin from the bottom of the impregnation chamber back to the top of the impregnation chamber. With the stirring of the stirring component and the electric heating tube, it can ensure the uniform temperature of the resin in the impregnation tank and stabilize the permeation process.

[0032] When in use, the insert 26 on the sealing cap 2 is aligned with the slot 27 and inserted to form a stable and reliable seal. The vacuum pump 21 and the air pipe 22 work together to extract air from the impregnation tank 1. The pressure gauge 23 can detect the pressure inside the impregnation tank 1. The air valve 24 can be used to release the vacuum. The liquid filling pipe 25 is connected to the resin feeding tank and is used to inject resin into the impregnation tank 1.

[0033] Combined with appendix Figures 2 to 6 As shown, the impregnation tank 1 is provided with an immersion chamber 3, and the immersion chamber 3 is provided with a stirring assembly and a circulation assembly. The stirring assembly includes multiple stirring paddles 4. The bottom of the immersion chamber 3 is provided with a fixed frame 5, and a rotating shaft 6 is rotatably connected to the fixed frame 5. The multiple stirring paddles 4 are arranged in a circumferential array on the rotating shaft 6. A rotating shaft 7 is rotatably connected to the sealing cover 2. A motor 8 is provided on the sealing cover 2. One end of the rotating shaft 7 is connected to the output end of the motor 8. The top of the rotating shaft 6 is provided with a slot 9, and the bottom of the rotating shaft 7 is provided with a locking piece 10 that cooperates with the slot 9. Both the locking piece 10 and the slot 9 are cross-shaped structures. The locking piece 10 is inserted into the slot 9 to connect the rotating shaft 6 and the rotating shaft 7 so that the motor 8 can drive the stirring paddles 4 to rotate.

[0034] Combined with appendix Figure 4 As shown, the circulation assembly includes a circulation pump 11 fixedly disposed outside the impregnation tank 1. The circulation pump 11 is connected to a liquid pipe 12 and a liquid pipe 13, which are respectively connected to the bottom and top of the impregnation tank 1. The bottom of the soaking chamber 3 has an inverted conical structure, and the liquid pipe 12 is connected to the center of the bottom of the soaking chamber 3. This structure can help the resin to be discharged better. A drain pipe 20 is connected to the liquid pipe 12, and a valve is connected to the drain pipe 20.

[0035] Combined with appendix Figure 4 As shown, the impregnation tank 1 has multiple electric heating tubes 14 arranged in an array inside the jacket. The electric heating tubes 14 can help the resin maintain a certain temperature condition and prevent the resin from curing.

[0036] Combined with appendix Figure 4 and Figure 7As shown, multiple arc-shaped fixing plates 15 are equidistantly arranged on the inner wall of the soaking chamber 3.

The fixing rods 17 on the placement plate 16 can be inserted into the sleeve 18 of the upper layer. The nanocrystalline magnetic ring is sleeved on the fixing rod 17, thereby limiting the movement range of the nanocrystalline magnetic ring and preventing the nanocrystalline magnetic rings from colliding with each other and causing damage during resin stirring.

[0037] During the impregnation operation, the motor 8 drives the stirring paddle 4 to rotate. The shear force generated by the rotation of the stirring paddle 4 can drive the resin to flow, expel and break up the air bubbles contained in the resin. At the same time, the circulating pump 11 pumps the resin in the impregnation chamber 3 from the bottom to the top. Under the action of the stirring components, the resin is mixed evenly, preventing the components in the resin from settling. The two work together to keep the resin fluid, thereby overcoming the penetration resistance and helping the resin to penetrate more comprehensively and evenly into the tiny pores and gaps of the nanocrystals, improving the quality and effect of impregnation.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
