Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a fixed magnetic assembly of the present application, where the fixed magnetic assembly 1000 includes a magnet 1100.

The magnet 1100 includes an S pole (south pole) 1101 and an N pole (north pole) 1102, while the number of the magnets 1100 is plural, specifically, the number of the magnets 1100 is even. The present application does not limit the magnet parameters of the magnet 1100, such as the field strength, the material, etc., as long as the plurality of magnets 1100 are identical.

Meanwhile, the plurality of magnets 1100 are enclosed in a symmetrical structure in which a section parallel to the arrangement direction of the plurality of magnets 1100 is a centrosymmetric image, and magnetic axes of the plurality of magnets 1100 (the magnetic axes are symmetrical axes of the magnets 1100 passing through the S-pole 1101 and the N-pole 1102 at the same time) are parallel to each other, that is, the magnetic axes of the plurality of magnets 1100 extend in the same direction.

For convenience of illustration, any two adjacent magnets 1100 of the plurality of magnets 1100 are respectively defined as a first magnet 1110 and a second magnet 1120, wherein the magnetic poles of any two adjacent magnets 1100 of the plurality of magnets 1100 are opposite in direction (i.e., the magnetic field direction is opposite), that is, the south pole 1101 of the first magnet 1110 is directed opposite to the south pole 1101 of the second magnet 1120, and the north pole 1102 of the first magnet 1110 is directed opposite to the north pole 1102 of the second magnet 1120.

Specifically, the process of fixing magnetism using the above-mentioned magnetism fixing assembly 1000 includes:

the first step is as follows: the magnetic optically variable pigment and the UV gloss oil are mixed into the printing ink according to a certain proportion.

The second step is that: ink is applied to a substrate (e.g., paper).

The third step: the substrate is magnetically pinned using a pinning assembly 1000.

Wherein, in the process of fixing magnetism, the extending direction of the magnetic axis of the magnet 1100 is perpendicular to the surface of the substrate, and in the process of fixing magnetism, the position of the fixed magnetic assembly 1000 can be adjusted, the position at least comprises the distance between the fixed magnetic assembly 1000 and the substrate, and the direction of X, Y, Z of the fixed magnetic assembly 1000 (wherein, the X, Y, Z directions of the fixed magnetic assemblies 1000 are perpendicular to each other, and the Z direction of the fixed magnetic assembly 1000 is the thickness direction of the fixed magnetic assembly 1000).

The fourth step: and curing by using a UV lamp to finally obtain images with various 3D light variable effects.

Because the structure of the fixed magnetic assembly 1000 used in the present application is as described above, finally, the pattern on the printing material can be seen as a centrosymmetric pattern at a certain angle, and when the printing material is rotated 360 degrees or observed according to the rotation direction as shown in fig. 2, the pattern can be seen to have a dynamic 3D moving effect, and the image is very beautiful and sharp.

It will be appreciated that when different shaped magnets 1100 are used, the pattern on the substrate can exhibit a variety of different effects.

With continued reference to fig. 1, any adjacent two magnets 1100 of the plurality of magnets 1100 are in contact, i.e., the first magnet 1110 and the second magnet 1120 are in direct contact, and the adjacent two magnets 1100 are "attracted by opposite polarities" such that no fasteners are required to secure the fixed magnetic assembly 1000. Meanwhile, any two adjacent magnets 1100 can slide along the contact surface, specifically, under the action of external force, the first magnet 1110 can slide relative to the second magnet 1120, so that the structure of the fixed magnetic assembly 1000 can be adjusted.

In other embodiments, any two adjacent magnets 1100 may be spaced apart, that is, the first magnet 1110 and the second magnet 1120 are spaced apart from each other by a certain distance.

With continued reference to fig. 1, the end faces of the opposite magnetic poles of the first magnet 1110 and the second magnet 1120 are coplanar, that is, the end face of the S pole 1101 of the first magnet 1110 is coplanar with the end face of the N pole 1102 of the second magnet 1120, and the end face of the N pole 1102 of the first magnet 1110 is coplanar with the end face of the S pole 1101 of the second magnet 1120. In other embodiments, there may be a height difference between the end faces of the first magnet 1110 and the second magnet 1120 that have opposite magnetic poles.

With continued reference to fig. 1, the symmetrical structure enclosed by the plurality of magnets 1100 is axially arranged as a hollow structure, and no fixing member is filled in the symmetrical structure, so that the two adjacent magnets 1110 "attract each other" at this time, so that the fixed magnetic assembly 1000 is fixed without using any fixing member.

Continuing to refer to fig. 1, the magnet 1100 is a rectangular parallelepiped structure, the number of the magnets 1100 is four, the four magnets 1100 are enclosed to form a hollow rectangular parallelepiped, and the cross section of the rectangular parallelepiped along the direction perpendicular to the extension direction of the magnetic axis is a rectangle (which may be a square or a rectangle) having a hollowed area, wherein the hollowed area is also a rectangle (which may be a square or a rectangle).

In this case, after the magnetization, images taken from various angles with respect to the white substrate and the black-and-white contrast substrate are shown in fig. 3.

The printing stock is white, the printing stock is black-white, the printing stock is white-black contrast, the printing stock has a part of white and a part of black, and the pattern formed after the magnetizing is connected with the white part and the black part in a bridging manner.

Among them, the length of the magnet 1100 having a rectangular parallelepiped structure is 10cm or less (for example, 10cm, 8cm, or 4cm), preferably 5cm or less (for example, 5cm, 3cm, or 2cm), more preferably 3cm or less (for example, 3cm, 2.5cm, or 2cm), and most preferably 2.5 cm.

In other embodiments, the four magnets 1100 with the rectangular parallelepiped structure may be enclosed in a symmetrical structure with other shapes, and the number of the magnets 1100 with the rectangular parallelepiped structure in the fixed magnet assembly 1000 may be other, for example, 6 or 8.

Wherein, when the number of the magnets 1100 is 6, the image collected after the magnetization is as shown in fig. 5:

as can be seen from fig. 5, the image effect captured at this time is a dynamically changing "snowflake" 3D effect with a convex center.

Wherein, when the number of the magnets 1100 is 8, the image collected after the magnetization is as shown in fig. 6:

as can be seen from fig. 6, the image effect acquired at this time is a dynamically changing "sun"/"griffonia"/"boswellia" 3D effect.

Wherein, in the embodiment of FIG. 4, the outer diameter of the magnet 1100 is less than or equal to 10cm, preferably less than or equal to 5cm, and more preferably less than or equal to 3 cm; and/or the ratio of the outer diameter to the inner diameter of magnet 1100 is 10 or less, preferably 5 or less, and most preferably 2 to 2.5 (e.g., 2, 2.3, or 2.5), and/or the thickness of magnet 1100 is < 2cm, preferably < 1cm, more preferably < 0.5cm, and most preferably 0.2 to 0.3cm (e.g., 0.2cm, 0.25cm, or 0.3 cm).

Referring to fig. 7 and 8, unlike the previous embodiment, in this embodiment, the radial cross-section of the magnet 1100 is in the shape of an isosceles right triangle, and the legs of the radial cross-section of the first magnet 1110 abut the hypotenuse of the radial cross-section of the second magnet 1120 (as shown).

In the application scenario of fig. 7, the magnets 1110 are enclosed to form a hollow octagon, and the hollow area inside the octagon is also an octagon structure, but unlike the application scenario of fig. 7, in the application scenario of fig. 8, the hollow area inside the symmetrical structure is also an octagon structure, but the size of the octagon structure is smaller.

In the application scenarios of fig. 7 and 8, the lengths of the two right-angle sides of the isosceles right-angle shape are less than or equal to 10cm, preferably less than or equal to 5cm, and more preferably less than or equal to 2 cm.

Meanwhile, the Z direction (the Z direction is the same as the thickness direction of the fixed magnetic assembly 1000) of the fixed magnetic assembly 1000 corresponding to two rows of the outer circle is opposite.

As can be seen from fig. 9, the image effect acquired at this time may be a dynamically changing "star anise"/"octopus" 3D effect with a central bulge.

Wherein the fixed magnetic assembly 1000 of fig. 7 can be transformed into the fixed magnetic assembly 1000 of fig. 8 by sliding two adjacent magnets 1100.

The structure and arrangement of the magnet 1100 are specifically described above, but the present application is not limited thereto, and in other application scenarios, the structure and arrangement of the magnet 1100 may be other, and refer to fig. 10 specifically. In summary, the present application is not limited to the shape, size, material, number and other specific arrangement of the magnets 1100 as long as the plurality of magnets 1100 are enclosed in a symmetrical structure, the magnetic axes of the plurality of magnets 1100 are parallel to each other, and the magnetic poles of any two adjacent magnets 1100 in the plurality of magnets 1100 are opposite in direction.
