Wherein, the vacuum pressure impregnator 2 is arranged outside the shell 1, and the accommodating device 3, the vibrating device 4 and the heating device 5 are all arranged inside the shell 1. The impregnation inlet 31 of the accommodating device 3 is connected with the outlet 22 of the vacuum pressure impregnator 2 through a first pipeline 8, the first pipeline 8 is arranged on the side wall of the shell 1 in a penetrating way, one part of the first pipeline 8 is arranged in the shell 1, and the other part of the first pipeline 8 is arranged outside the shell 1. The glue dipping outlet 32 of the accommodating device 3 is connected with the inlet 21 of the vacuum pressure dipping machine 2 through a second pipeline 9, the second pipeline 9 is arranged on the side wall of the shell 1 in a penetrating way, one part of the second pipeline 9 is arranged in the shell 1, and the other part of the second pipeline 9 is arranged outside the shell 1.
The accommodating device 3 is used for accommodating a superconducting magnet 6 to be immersed. The vacuum pressure impregnator 2 is used for conveying the impregnating compound into the accommodating device 3, and sucking the impregnating compound after the accommodating device 3 is filled with the impregnating compound, so that the superconducting magnet 6 is impregnated in the accommodating device 3 by the impregnating compound. Specifically, after the accommodating device 3 is filled with the impregnating compound, the impregnating compound is continuously conveyed into the accommodating device 3, the impregnating compound in the accommodating device 3 is sucked, the sucked impregnating compound is conveyed into the vacuum pressure impregnator 2, and under the conveying and sucking actions of the vacuum pressure impregnator 2, the impregnating compound in the accommodating device 3 is impregnated in each gap of the superconducting magnet 6, so that each gap of the superconducting magnet 6 is ensured to be filled with the impregnating compound.
In specific implementation, the accommodating device 3 may be a metal grinding tool, and may also be a soft mold, where the soft mold refers to a mold made by winding a glass ribbon, a polytetrafluoroethylene ribbon, or a PPLP ribbon, and the like, and this embodiment does not limit this.
The vibration device 4 is used for vibrating the accommodating device 3, so that the superconducting magnet 6 in the accommodating device 3 is better impregnated by the impregnating compound under the vibration effect. Specifically, the vibration device 4 may be any vibration device as long as it can vibrate the accommodating device 3, and the embodiment does not limit this.
The heating device 5 is used for heating the accommodating device 3 so as to solidify the superconducting magnet 6 and the impregnating compound in the accommodating device 3. The heating device 5 heats the superconducting magnet 6 and the immersion glue after the superconducting magnet 6 is completely immersed in the immersion glue. In specific implementation, the heating device 5 may be an electric heating device, and may also be another device, which is not limited in this embodiment.
In specific implementation, the superconducting magnet 6 immersion device may further include: a temperature sensor.

The vacuum pressure impregnator 2 is stored with impregnating compound, starts the vacuum pressure impregnator 2, sets the pressurizing mode, and pressurizes the impregnating compound and conveys the impregnating compound to the inside of the accommodating device 3 through the first pipeline 8.

The vacuum pressure impregnator 2 continuously conveys the impregnating compound into the accommodating device 3 until the accommodating device 3 is filled with the impregnating compound. After the accommodating device 3 is filled with the impregnation glue, the outlet 22 of the vacuum pressure impregnator 2 still conveys the impregnation glue into the accommodating device 3 through the first pipeline 8, meanwhile, the pressurization mode of the vacuum pressure impregnator 2 is changed into the vacuum mode, the impregnation glue in the accommodating device 3 is sucked through the impregnation outlet 32 of the accommodating device 3, and the sucked impregnation glue is conveyed to the inside of the vacuum pressure impregnator 2 through the inlet 21 of the vacuum pressure impregnator 2 through the second pipeline 9. Because the vacuum pressure impregnator 2 still continuously conveys the impregnating compound to the accommodating device 3 in the suction process, the vacuum pressure impregnator 2 sucks the impregnating compound, so that the impregnating compound conveyed into the accommodating device 3 is better immersed into each gap of the superconducting magnet 6 under the suction effect. And, during the pumping, the vibration device 4 keeps vibrating the accommodating device 3, so that the superconducting magnet 6 is completely immersed by the immersion paste. After the above-mentioned conveying and pumping are continued for a preset time, the heating device 5 heats the accommodating device 3 to solidify the superconducting magnet 6 and the impregnating gel phase.

When the impregnation glue is present, indicating that the housing device 3 is filled with the impregnation glue, the vacuum pressure impregnator 2 may suck the impregnation glue.

In specific implementation, the preset volume may be determined according to actual conditions, and this embodiment does not limit this. In specific implementation, the transmission medium may be oil or other liquid, and this embodiment does not limit this.
The vibrator of the ultrasonic vibration device is placed in the transmission medium, and the vibrator is used for vibrating the transmission medium to vibrate the accommodating device 3. Specifically, the vibrator of the ultrasonic vibration device may be a vibration probe, and the vibrator vibrates the transmission medium, and since the accommodating device 3 is at least partially disposed in the transmission medium, the vibration of the transmission medium is transmitted to the accommodating device 3 to vibrate, so that the superconducting magnet 6 in the accommodating device 3 vibrates.

Specifically, the layers of superconducting coils 61 are placed side by side in order. As shown in fig. 3, the layers of superconducting coils 61 may be sequentially arranged in the order from top to bottom in fig. 3, so that the layers of superconducting coils 61 are placed in the accommodating device 3. The glass ribbon 62 is N layers, the superconducting coils 61 are N +1 layers, N is greater than or equal to 1, and the superconducting coils 61 of each layer are bound and fixed through the glass ribbon 62, so that the superconducting coils 61 of each layer are kept in an original state of being sequentially arranged, namely, the superconducting coils 61 of each layer are not loose.
In a specific embodiment, the binder 7 of the superconducting magnet 6 is disposed outside the outermost superconducting coil 61. When the binder 7 is a glass filament or a glass filament ribbon, the glass filament or the glass filament ribbon is wound around the outer portion of the outermost superconducting coil 61.
It can be seen that, in the embodiment, the superconducting magnet 6 is more stable, so that loosening under the action of the vibrating device 4 is avoided, and the binding piece 7 arranged outside the superconducting magnet 6 is combined, so that the stability and the loosening of the superconducting magnet 6 are effectively guaranteed.
Referring to fig. 1 and 2, in the above embodiments, the dipping inlet 31 is opened at the bottom of the accommodating device 3, and the dipping outlet 32 is opened at the top of the accommodating device 3.
