[0079] This application provides a magnetic orientation device, please refer to Figure 2 As shown, Figure 2 1 is a schematic diagram of the structure of an embodiment of the magnetic orientation device provided by the present application. Specifically, the magnetic orientation device 10 includes: a plurality of first magnets 11, and the plurality of first magnets 11 are arranged in a single layer. That is, the magnetic orientation device 10 of the present application has only a single-layer structure, which is easy to use and has good practicality.

[0080] Furthermore, the magnetic axes of the plurality of first magnets 11 are parallel to the plane of the substrate 20. The plurality of first magnets 11 are arranged to form a regular polygon or a partial side of a regular polygon, wherein the number of sides of the regular polygon is an even number greater than or equal to 4.

[0081] For example, in Figure 2 In the embodiment shown, the magnetic orientation device 10 includes 6 first magnets 11, wherein the 6 first magnets 11 are arranged to form a regular hexagon. Figure 4 As shown, the magnetic orientation device 10 may also include eight first magnets 11, with the eight first magnets 11 arranged to form a regular octagon. In other embodiments, the regular polygon may also be a regular quadrilateral, a regular dodecagon, etc., which are not listed here. Preferably, the regular polygon may be a regular hexagon or a regular octagon, and most preferably, a regular hexagon. Please refer to the following embodiments for details.

[0082] Optionally, in some embodiments, the south / north poles of all first magnets 11 face the same direction, where the south / north pole direction of the first magnets 11 refers to whether the south / north poles of the first magnets 11 face the interior or the exterior of the regular polygon. That is, the south poles of all first magnets 11 face the interior of the regular polygon, and the north poles face the exterior of the regular polygon; or, the south poles of all first magnets 11 face the exterior of the regular polygon, and the north poles face the interior of the regular polygon.

[0083] For example, Figure 2 As shown, the south poles of the six first magnets 11 are all facing the inside of the regular hexagon, and the north poles are all facing the outside of the regular hexagon. That is, in this embodiment, the south / north poles of the first magnets 11 are in the same direction and point to the center of the regular hexagon, and the six first magnets 11 are arranged in a central symmetric manner. In this embodiment, Figure 1 The schematic diagram of the printed pattern of this embodiment is obtained by the rotation observation method shown in FIG. Figure 3 As shown in the effect diagram of this embodiment, a convex "disc" effect is formed in the middle of the regular hexagon. Figure 3 From left to right are the effect pictures obtained at a distance of 0, 3, and 6 mm from the substrate, and from top to bottom are the patterns observed from directly above (0°~5°), (25°~30°), and (45°~60°) at each distance, that is, Figure 3 (a)-(c) are the effects obtained from directly above (0°~5°) at distances of 0, 3, and 6 mm from the substrate respectively;

[0084] Figure 3 (d)-(f) in the middle are the effects obtained from the top (25°-30°) at a distance of 0, 3, and 6 mm from the substrate respectively; Figure 3 (g)-(i) in the middle are the effect pictures obtained at a distance of 0, 3, and 6 mm from the substrate respectively from the top (45°~60°).

[0085] For example, Figure 4 As shown, in the regular octagon, the south poles of the eight first magnets 11 face the outside of the regular octagon, and the north poles face the inside of the regular octagon.

[0086] In other embodiments, among the plurality of first magnets 11, some first magnets 11 have their south poles facing outside the regular polygon and their north poles facing inside the regular polygon, while another portion of the first magnets 11 have their south poles facing inside the regular polygon and their north poles facing outside the regular polygon. That is, among the plurality of first magnets 11, some first magnets 11 have opposite orientations.

[0087] Optionally, the south poles and north poles of adjacent first magnets 11 are oriented in opposite directions. Figure 5As described above, the six first magnets 11 are arranged to form a regular hexagon, wherein the south poles and north poles of three first magnets 11 are oriented oppositely to the other first magnets 11, and are spaced apart from each other, that is, the orientations of adjacent first magnets 11 are opposite. The printed pattern obtained in this embodiment is as follows Figure 6 As shown, the rendering is: "Morning Glory Blooms" / "Jewish Symbols", Figure 6 The three figures (A), (B), and (C) are the patterns viewed from directly above (0°~5°), (25°~30°), and (45°~60°), respectively. Figure 6 The middle (D) is the pattern seen after being rotated 30° when observed at an angle of 45° to 60°. This embodiment has a strong 3D change effect.

[0088] Alternatively, as Figure 7 As shown in FIG. 1 , in this embodiment, there are six first magnets 11 on the periphery, of which five have their north and south poles facing the same direction and pointing to the center of the regular hexagon (center symmetry), and the south and north poles of the other first magnets 11 are opposite to those of the other first magnets 11. The printed pattern obtained in this embodiment is shown in FIG. Figure 8 As shown, the effect diagram is: "Corona", Figure 8 The four pictures from ad (left to right) are the patterns viewed from observation angles of (-25° to -30°), directly above (0° to 5°), (25° to 30°), and (45° to 60°), respectively, with a strong 3D change effect.

[0089] Alternatively, as Figure 9 As shown in FIG. 1 , in this embodiment, of the six first magnets 11 on the periphery, four have their south and north poles facing the same direction and pointing toward the center of the circle (center symmetry), and the other two have their south and north poles facing in the opposite direction to the other magnets (they are positioned oppositely, i.e., two magnets apart). The printed pattern obtained in this embodiment is shown in FIG. Figure 10 As shown, the rendering is: "Double Moon Bay", Figure 10 In middle af, the left and right sides are horizontal and vertical observations respectively, and from top to bottom they are the patterns observed from directly above (0°~5°), (25°~30°), and (45°~60°), respectively, with a very strong 3D change effect.

The printed pattern obtained in this embodiment is as follows: Figure 12 As shown, the effect picture is: "Flying Squirrel", Figure 12The patterns from top to bottom are (-45°~-60°), (-25°~-30°), directly above (0°~5°), (25°~30°), and (45°~60°), with a very strong 3D changing effect.

[0091] Alternatively, as Figure 13 As shown, in this embodiment, of the six first magnets 11 on the periphery, the south poles and north poles of four of the first magnets 11 are oriented in the same direction and point to the center of the regular hexagon (central symmetry), and the south poles and north poles of the other two first magnets 11 are oriented in the opposite direction to the other magnets (they are positioned adjacent, i.e., there is no separation between the magnets). The printed pattern obtained in this embodiment is as follows: Figure 14 As shown, the effect diagram is: "normal distribution", Figure 14 In the figure, the patterns from top to bottom are (-45°~-60°), (-25°~-30°), directly above (0°~5°), (25°~30°), and (45°~60°), which have a very strong 3D changing effect.

[0092] In other embodiments, the first magnets 11 may also form partial sides of a regular polygon, for example, Figure 15 As shown, the magnetic orientation device 10 includes three first magnets 11, which are the three sides of a regular hexagon and are placed in an interspaced manner. The south and north poles of the three first magnets 11 face the same direction (pointing to the center of the regular hexagon) and are placed in an interspaced manner. The printed pattern obtained in this embodiment is as follows: Figure 16 As shown, the effect diagram is: "triangular pyramid" 3D effect. Figure 16 In the figure, (A), (B), and (C) from left to right are the views from directly above (0°~5°), (25°~30°), and (45°~60°), respectively. Figure 16 A faint "triangular pyramid" 3D effect appears in the area within the dotted line in (A), as shown in (A), (B), and (C). This special 3D effect develops from nothing to something, from weak to strong, from a shallow broken line to a "boomerang" shape, and finally gradually approaches a triangle.

[0093] In other embodiments, Figure 17 As shown, the magnetic orientation device 10 also includes a plurality of second magnets 12, which are located in a regular polygon and are centrally symmetrically arranged and rotated around the center of the regular polygon. The magnetic axes of the plurality of second magnets 12 are parallel to the plane of the substrate 20, and the second magnets 12 are also a single-layer structure.

[0094] Optionally, the plurality of second magnets 12 may be arranged with the same poles facing each other or with opposite poles facing each other. Alternatively, some of the plurality of second magnets 12 may be arranged with the same poles facing each other, while another portion of the plurality of second magnets 12 may be arranged with opposite poles facing each other. Alternatively, the plurality of second magnets 12 may be arranged in a straight line, with the south poles and north poles of the second magnets 12 arranged in a straight line facing the same direction or opposite directions.

[0095] Among the first magnets 11 and the second magnets 12 , at least a portion of the first magnets 11 and / or the second magnets 12 are parallel to each other, and the magnetic poles of the parallel magnets are oriented in the same or opposite directions.

[0096] The first magnet 11 and the second magnet 12 can be placed adjacent to each other so that opposite poles attract each other, or placed adjacent to each other so that like poles repel each other.

[0097] The magnetic orientation device 10 of the present application has a simple structure. The first magnet 11 and the second magnet 12 can be common magnets. The first magnet 11 and the second magnet 12 are in the shape of long strips. No special processing is required for the magnets, and the positions of the magnets are fixed. It not only has certain advantages in printing speed, quantity and method, but also has good consistency in the printed patterns.

[0098] exist Figure 17 In the embodiment shown, the outer circumference of the six first magnets 11 has three of them with their north and south poles pointing to the center of the regular hexagon and the other three away from the center of the regular hexagon, and they are spaced apart in pairs. The magnetic axes of the six second magnets 12 in the inner circle are arranged symmetrically around the center of the regular hexagon, and are placed at 60 degrees. The printed pattern obtained in this embodiment is as follows: Figure 18 As shown, the effect diagram is: a "lucky clover" pattern, Figure 18 From left to right, (A), (B), and (C) are the views from directly above (0° to 5°), (25° to 30°), and (45° to 60°), respectively.

[0099] Alternatively, as Figure 19 As shown in FIG. 1 , in this embodiment, the six first magnets 11 on the outer periphery have their north and south poles facing the same direction and pointing to the center of the regular hexagon (center symmetry), and the magnetic axes of the six second magnets 12 on the inner circle are rotated around the center of the circle in a center symmetric manner and are placed at 60°. The printed pattern obtained in this embodiment is as shown in FIG. Figure 20 As shown, the effect is: "petal" and "orange petal" Figure 20 In the figure, (A), (B), and (C) are respectively directly above (0°~5°), (25°~30°), and (45°~60°), and (D) is the pattern seen when the pattern is rotated 30° at (45°~60°).

[0100] Alternatively, as Figure 21As shown in FIG. 1 , in this embodiment, there are six first magnets 11 on the periphery, three of which have their north and south poles pointing toward the center of the regular hexagon and three away from the center of the regular hexagon, and are spaced two by two. There are six second magnets 12 on the inner circle, and the south and north poles of the six second magnets 12 are facing each other at 60 degrees. The printed pattern obtained in this embodiment is shown in FIG. Figure 22 As shown, the effect is: "snowflakes", Figure 22 (A) and (B) are the images obtained from directly above (0°~5°), (25°~30°), (45°~60°), and (45°~60°) rotated 30° with the substrate spaced 0 and 3 mm apart, respectively.

[0101] Alternatively, as Figure 23 As shown, in this embodiment, there are 6 first magnets 11 on the periphery, 3 of which have their south and north poles pointing to the center of the regular hexagon, and 3 away from the center of the regular hexagon, and are spaced apart in pairs. The magnetic axes of the 3 second magnets 12 in the inner circle rotate around the center of the regular hexagon in a centrosymmetric manner. It should be noted that the south and north poles of the inner circle are opposite to those of the outer circle and are placed at 60 degrees. The printed pattern obtained in this embodiment is as follows Figure 24 As shown, the effect is: it is in the shape of a "monkey face". Figure 24 In the figure, (A), (B), and (C) from left to right are the views from directly above (0°~5°), (25°~30°), and (45°~60°), respectively.

[0102] Alternatively, as Figure 25 As shown, in this embodiment, there are 6 first magnets 11 on the periphery, and the south / north poles of 3 first magnets 11 point to the center of the regular hexagon and the centers of 3 regular hexagons, and are spaced apart in pairs. The magnetic axes of the 3 second magnets 12 in the inner circle rotate around the center of the regular hexagon as if the center is symmetrical. It should be noted that the south / north poles of the second magnets 12 in the inner circle and the first magnets 11 in the outer circle are of the same polarity relative to each other. The printed pattern obtained in this embodiment is as shown Figure 26 As shown, the effect diagram is "crystal structure".

[0103] Alternatively, as Figure 27 As shown, in this embodiment, the outer circumference of the six first magnets 11, the south and north poles of the first magnets 11 are in the same direction and point to the center of the regular hexagon (centrosymmetry), and the magnetic axes of the inner circumference of the three second magnets 12 are rotated around the center of the regular hexagon as centrosymmetry, with an interval of 120 degrees. The printed pattern obtained in this embodiment is as follows Figure 28 As shown, the effect is similar to the "propeller of a ship". Figure 28 From left to right, (A), (B), and (C) are the views from directly above (0° to 5°), (25° to 30°), and (45° to 60°), respectively.

[0104] Alternatively, as Figure 29 As shown, in this embodiment, there are six first magnets 11 on the outer periphery, and the south and north poles of the first magnets 11 are oriented in the same direction and point to the center of the regular hexagon (central symmetry), and the two second magnets 12 on the inner circle are placed at 60 degrees to each other, with the same poles facing each other (the same polarity inside and outside), as shown. Figure 30 As shown, the second magnet 12 in the inner circle can also be opposite to the first magnet 11 in the outer circle (differentiated inside and outside). Figure 31 As shown, the effect picture is: "flower bud", Figure 31 In the figure, (A) and (B) are two placement methods in the embodiment, which are the patterns viewed from directly above (0°~5°), (25°~30°), and (45°~60°) from top to bottom.

[0105] Alternatively, as Figure 32 As shown, in this embodiment, there are 6 first magnets 11 on the outer periphery, and the south / north poles of the first magnets 11 are oriented in the same direction and point to the center of the regular hexagon (central symmetry), and the two second magnets 12 on the inner circle are placed at 120 degrees to each other, with the same poles facing each other (the same polarity inside and outside), as shown. Figure 33 As shown, the second magnet 12 in the inner circle can also be opposite to the first magnet 11 in the outer circle (differentiated inside and outside).
