Asymmetrical distribution of magnetic poles and precise positioning of magnetic poles: By controlling the forming process of the plastic magnetic roller and the secondary precision magnetization, the magnetic poles will appear 3 N poles and 2 S poles, and the magnetic poles can be accurately positioned to an accuracy of ±1.5°. The asymmetric distribution of the magnetic poles is realized, and the distribution of the magnetic field must be accurately controlled during the magnetization process, which greatly improves the clarity of the copy. The pole position tolerance of similar foreign products is ±3°. In the past, it was very difficult to check the magnetic force of the magnetic field and the distribution of the magnetic poles. During the development of the magnetic roller, the company’s technicians used computers to realize the detection of 2000 points in the circumferential direction and one point per 100μm in the axial direction, leading the country. status.
Introducing the concept of pole width: the distinction between high magnetic strength and wide magnetic strength has a direct impact on the effect of the copy. By controlling the magnetization, the distribution of high magnetic strength and wide magnetic strength can be achieved to achieve the best effect.
Achieved the uniformity of the coaxial magnetic core force: It is extremely difficult to control the uniformity of the coaxial magnetic core force for magnets with a length of more than 100MM. This project visually improves the coaxial magnetic force uniformity by improving the injection molding alignment and magnetization accuracy. , Reaching 2MT/4MM.
