DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 3 The utility model provides a technical solution: a copper-clad laminate multi-pole planar magnetizing fixture, comprising a heat dissipation base 1, a substrate 2 and a copper-clad laminate body 3, the heat dissipation base 1 is fixed to the substrate 2 by bolts, the substrate 2 and the heat dissipation base 1 are nested, the copper-clad laminate body 3 is arranged on the substrate 2, the heat dissipation base 1 is fixed to the first positioning plate 6 by bolts, and the heat dissipation base 1 is fixed to the second positioning plate 7 by bolts.

[0023] A circulating water channel is provided inside the heat dissipation base 1, and one end of the circulating water channel inside the heat dissipation base 1 is interconnected with the water inlet 101, and the other end of the circulating water channel inside the heat dissipation base 1 is interconnected with the water outlet 102, and the water outlet 102 and the water inlet 101 are both fixed on the heat dissipation base 1; the copper clad laminate body 3 is etched with pole pitches at equal intervals, and the upper end surface of the copper clad laminate body 3 is flush with the upper end surface of the heat dissipation base 1; one end of the copper clad laminate body 3 is interconnected with the magnetizing power input line 4, and the other end of the copper clad laminate body 3 is interconnected with the magnetizing power output line 5; the first positioning plate 6 is flush with the front side of the copper clad laminate body 3, and the maximum distance between the first positioning plate 6 and the second positioning plate 7 is equal to the width of the copper clad laminate body 3; the second positioning plate 7 is symmetrically fixed with a bracket 8, and a magnetic core 9 is fixed on the bracket 8, and the magnetic core 9 is located directly above the copper clad laminate body 3;

[0024] When using the copper-clad multi-pole planar magnetizing fixture, Figure 1-Figure 3As shown, by connecting the water outlet 102 and the water inlet 101 to the cooling water pipe, the cooling water can be circulated in the heat dissipation base 1 in cooperation with the water pump, thereby providing a basic guarantee for the cooling of the device, and then adjusting the positions of the first positioning plate 6 and the second positioning plate 7 according to actual needs, so as to realize the positioning of the long permanent magnetic material, and ensure that the long permanent magnetic material is located directly above the copper clad board body 3 after installation, and then power is supplied to the entire device, and the current generated by the copper wire layer of the copper clad board body 3 is used for magnetization, so that the magnetization magnetic field is arranged in an orderly manner, and the magnetic circuit is closed through the action of the magnetic conductive core 9 above, thereby forming a planar multi-pole magnetization magnetic field, and then the magnetization effect of the long permanent magnetic material can be realized;

[0025] And in the actual use process, it is necessary to pay attention to controlling the size of the discharge current and the discharge interval, which is conducive to heat dissipation. In order to increase the magnetic field strength, the common practice in the past was to increase the current of the fixture under a specific state. Although this can play a certain role, it will cause the fixture to heat up rapidly. Although there is water cooling, the heating state cannot be effectively suppressed, which causes the fixture to be damaged in a short time and returned to the factory for repair. Based on the above situation, the inventor has increased the magnetizing interval of the copper-clad multi-pole planar magnetizing fixture through practice, so that the copper-clad multi-pole planar magnetizing fixture can be fully cooled, effectively ensuring the continuous and reliable use of the magnetizing fixture. This is the working principle of the copper-clad multi-pole planar magnetizing fixture.
