The present application also provides a process for preparing a magnetic member, for manufacturing the magnetic member, referring to fig. 16, fig. 16 is a flowchart of a process for preparing a magnetic member according to an exemplary embodiment, as shown in fig. 16, the process for preparing a magnetic member specifically includes the following steps:
Step S11, cutting a material to be cut to obtain a ring body, wherein the ring body comprises: the device comprises a first ring body, a second ring body and a guide ring body.
In specific practice, the ring body is integrally formed.
In specific practice, the cutting of the material to be cut in step S11 to obtain a ring body specifically includes:
The method comprises the steps that a material to be cut is punched and multi-wire cutting is adopted, and a ring body is obtained; or alternatively
And (5) cutting the material to be cut by using a laser cutting mode to obtain the ring body.
Step S12, processing the surface of the ring body to obtain a target ring body corresponding to each ring body, wherein the target ring body comprises: the device comprises a first target ring body, a second target ring body and a guiding target ring body.

For example: plating three layers, namely nickel-copper-nickel, which can protect the magnetized magnetic member from cracking and corrosion in ambient air; or a galvanised coating for protecting the magnetized magnetic member from corrosion in the surrounding air and providing a gentle protection against moisture, water or salt water.
And S13, radial radiation magnetizing is carried out on the guide target ring body, and the guide magnetic ring is obtained.
It can be understood that after radial radiation magnetization is performed on the guide magnetic ring, two situations exist in the magnetic poles of the guide magnetic ring: one is that the magnetic pole polarity of the outer diameter side of the guide magnetic ring is N pole and the magnetic pole polarity of the inner diameter side is S pole; the other is that the magnetic pole polarity of the outer diameter side of the guide magnetic ring is S pole and the magnetic pole polarity of the inner diameter side is N pole.

In the step S144, in addition to the first target ring body, the guide magnetic ring and the second target ring body which are required to be extruded, the glue between the first target ring body, the guide magnetic ring and the second target ring body is required to be solidified for auxiliary adhesion; and if glue overflows, the glue is required to be cleaned. In the application, needle tubes are used for dispensing glue on the inner wall and the outer wall of the magnetic ring of the guide magnetic ring.
