In addition, the second aspect of the present application further provides a fixed magnetic curing method, where the fixed magnetic curing method is applied to the fixed magnetic curing apparatus according to the first aspect, referring to fig. 6, fig. 6 is a schematic flow chart of an embodiment of the fixed magnetic curing method of the present application, and the fixed magnetic curing method includes:
s11: based on the conveying platform, conveying the to-be-processed piece along a first direction, wherein the to-be-processed piece is printed with magnetic ink patterns;
for continuous processing of the workpiece 20, a transfer platform 10 may be generally used, and by enabling the transfer platform 10, the workpiece 20 disposed on the transfer platform 10 may be continuously transferred, and various operations may be performed on the workpiece 20.
Since the magnetic ink pattern 21 is printed on the member to be processed 20, the magnetic ink pattern 21 is usually wet before the magnetic material is not cured, so that the magnetic ink pattern 21 on the member to be processed 20 can be magnetized when the member to be processed 20 enters the magnetic field as the member to be processed 20 is conveyed, that is, pigment flakes of the magnetic ink pattern 21 are regularly arranged under the influence of the magnetic field.
S12: magnetizing a part of the pattern of the magnetic ink pattern by a magnetic field generated by the magnetic field generating means;
the magnetic field generating mechanism 30 at least includes a plurality of magnet elements, and through reasonable mutual matching among the plurality of magnet elements, an enhanced magnetic field can be formed, for example, as shown in fig. 5, the magnet elements can be respectively arranged at the first openings on two sides of the light blocking member 50 and the member to be processed 20, and the two magnet elements are separated from the light blocking member 50 and the member to be processed 20, so that a first magnetic field can be formed, and when a part of the patterns of the magnetic ink patterns 21 in the regular arrangement enter the first magnetic field, the first magnetic field can be used for magnetizing a part of the patterns of the magnetic ink patterns 21.
S13: based on the fact that the magnetized partial pattern is transmitted to an irradiation area of a curing light source along a first direction, the partial pattern is fixed magnetically and cured by matching with a part of opening of the light blocking piece;
as a result of the continued operation of the transfer platform 10, the magnetized partial pattern on the piece to be treated 20 is transferred in the first direction A-A through the first magnetic field. Because the curing light source 40 can form an irradiation area through the first opening area 52 of the light blocking member 50, when the magnetized partial pattern is transferred to an irradiation area of the curing light source 40, the LED lamps have a drying function because of the plurality of LED lamps on the curing light source 40, so that moisture in the magnetized partial pattern can be dried, and the magnetized partial pattern is fixed magnetically and cured.
The curing light source 40 may include light sources such as ultraviolet light, infrared light, and thermal radiation, and the curing light source 40 may flash or be normally bright, which is not limited herein. Specifically, the curing light source 40, the magnetic field generating mechanism 30 and the light blocking member 50 are located at the same station, so that the functions of magnetization and fixed magnetization can be completed at one station, and the integration level of the device and the fixed-magnetization curing efficiency are improved.
S14: transmitting the cured partial pattern to a magnetic field along a first direction, and magnetizing the other partial pattern of the magnetic ink pattern;
as shown in fig. 5, the magnet members may be disposed at the second openings on both sides of the light blocking member 50 and the member to be processed 20, respectively, and the two magnet members may be separated from the light blocking member 50 and the member to be processed 20, so that a second magnetic field may be formed, and when another part of the patterns of the magnetic ink patterns 21 arranged regularly enter the second magnetic field along the first direction A-A, the second magnetic field may be used to magnetize another part of the patterns of the magnetic ink patterns 21.
S15: based on the fact that the magnetized other part of the pattern is transmitted to the other irradiation area of the curing light source along the first direction, the other part of the pattern is fixed magnetically and cured in cooperation with the other part of the opening of the light blocking piece, and therefore the piece to be processed forms a preset pattern.
With continued operation of the transfer platform 10, another portion of the pattern after magnetization on the member to be processed 20 is transferred in a first direction A-A through a second magnetic field. Because the curing light source 40 can form another irradiation area through the second opening area 53 of the light blocking member 50, when the magnetized partial pattern is transferred to the other irradiation area of the curing light source 40, the moisture in the magnetized partial pattern can be dried due to the plurality of LED lamps 42 on the curing light source 40, so that the magnetized partial pattern is fixed and cured, and the magnetized partial pattern is combined with the previous fixed partial pattern to form the preset pattern.
In addition, at the first open area 52, a first bright stripe tends to be formed during the fixed magnetic curing. At the second open area 53, a second bright stripe tends to form during the fixed magnetic curing process, where the first bright stripe is cured and is no longer affected. This is because the uncured magnetic ink can be fixed and cured again due to the shielding of the light blocking member 50, forming a plurality of bright stripes or yin-yang effects, and even forming a 3D stereoscopic pattern, which significantly improves the display effect of the pattern.
Therefore, the present application provides a fixed magnetic curing apparatus, in which a plurality of openings 51 are provided on the light blocking member 50, and the preset patterns to be processed can be magnetized and cured respectively in segments by cooperating with the magnetic field generating mechanism 30 and the curing light source 40; and the magnetic field generating mechanism 30, the curing light source 40, the light blocking member 50 and other components are reasonably arranged in space, so that the integration level of the components is high and the components can be positioned at the same station, thereby reducing the volume of the equipment and improving the efficiency.
The foregoing description is only a partial embodiment of the present application, and is not intended to limit the scope of the present application, and all equivalent devices or equivalent process transformations made by using the descriptions and the drawings of the present application, or direct or indirect application to other related technical fields, are included in the patent protection scope of the present application.
