[0044] The manufacturing method of the film assembly according to the embodiments of the present application, the film assembly 100, the shell 200 and the electronic device will be described below in combination with Figure 1 As shown in the figure, the manufacturing method comprises:

[0045] Step 502: sequentially printing a plurality of pattern layers on the film body by a plurality of magnetic plates; wherein the orthographic projection of the plurality of magnetic plates and the pattern lines of the plurality of pattern layers on the film body intersect.

[0046] In the embodiment, the plurality of magnetic plates are used to print the plurality of pattern layers on the film body respectively, the film body can carry the plurality of pattern layers, the film body printed with the pattern layers can be attached to the shell of the electronic device, and the appearance of the electronic device is more beautiful. Since the plurality of magnetic plates are used to print the plurality of pattern layers on the film body respectively, and the plurality of magnetic plates correspond to the plurality of pattern layers, the printed pattern is more abundant, and the level of the printed pattern is improved. Since the plurality of magnetic plates are used to print the plurality of pattern layers on the film body respectively, different magnetic plates can be used to print each pattern layer when the pattern layers are printed, and the lines of the patterns of the plurality of pattern layers can be arranged in a cross manner, and the patterns of different colors in the plurality of pattern layers can also be arranged in a cross manner, and the level of the printed pattern layers is further improved. The lines of the patterns of the plurality of pattern layers can be arranged in a cross manner, the patterns of different colors in the plurality of pattern layers can also be arranged in a cross manner, the process difficulty of printing a complex pattern is reduced, the efficiency of printing the film assembly is improved, and the cost of printing the film assembly is reduced. The plurality of magnetic plates intersect with the orthographic projection of the pattern lines of the plurality of pattern layers on the film body, the level of the printed pattern is further improved, the complex pattern is easily printed, the difficulty of printing the complex pattern is reduced, and the efficiency of printing the complex pattern is improved.

[0047] Specifically, by designing the pattern of the magnetic plate for printing the pattern layer, applying a plurality of magnetic plates to superimpose different effects, printing the magnetic pattern on the film body multiple times, and gradually forming a layer-by-layer pattern effect on a specific magnetic plate, and respectively solidifying and forming, a cross and multi-level pattern appearance effect can be achieved.

[0048] Specifically, the plurality of pattern layers can be printed by magnetic ink.

[0049] According to some embodiments of the present application, the plurality of pattern layers include a first pattern layer and a second pattern layer, and the plurality of pattern layers are printed on the film body by the plurality of magnetic plates in sequence, including: printing and solidifying the first pattern layer on the film body; printing and solidifying the second pattern layer on the film body.

[0050] In the embodiment, the first pattern layer is printed and solidified on the film body, and the second pattern layer is printed and solidified on the film body, so that the first pattern layer and the second pattern layer are superimposed, the level of the printed pattern is further improved, the complex pattern is easily printed, the difficulty of printing the complex pattern is reduced, and the efficiency of printing the complex pattern is improved.

[0051] According to some embodiments of the present application, the silk printing and solidifying the first pattern layer on the film body comprises: silk printing the first pattern layer on the film body; placing the film body on the first magnetic plate; heating the film body and the first magnetic plate at a first solidifying temperature for a first solidifying duration; separating the film body from the first magnetic plate; placing the film body at a first resting temperature for a first resting duration; heating the film body at a second solidifying temperature for a second solidifying duration; wherein the magnetic force lines of the first magnetic plate correspond to the pattern of the first pattern layer.

[0052] In this embodiment, the first ink layer is silk printed on the film body; the film body is placed on the first magnetic plate, so that the first ink layer forms a corresponding pattern according to the magnetic force lines on the first magnetic plate. The film body and the first magnetic plate are heated at a first solidifying temperature for a first solidifying duration, so as to realize the pre-solidification of the first ink layer, and avoid the change of the pattern formed by the first ink layer when the film body is taken off the first magnetic plate. The film body is heated at a second solidifying temperature for a second solidifying duration, so as to realize the secondary solidification of the first ink layer, and form a stable first pattern layer on the film body.

[0053] Further, after the film body and the first magnetic plate are heated at the first solidifying temperature for the first solidifying duration, the film body is taken off the first magnetic plate, and the film body is placed at a first resting temperature for a first resting duration, and then the film body is heated at a second solidifying temperature for a second solidifying duration.

[0054] According to some embodiments of the present application, the first solidifying temperature is greater than or equal to 40 degrees Celsius and less than or equal to 90 degrees Celsius; the first resting temperature is greater than or equal to 18 degrees Celsius and less than or equal to 35 degrees Celsius; the second solidifying temperature is greater than or equal to 70 degrees Celsius and less than or equal to 100 degrees Celsius; the first solidifying duration is greater than or equal to 0.5 minutes and less than or equal to 3 minutes; the first resting duration is greater than or equal to 1 hour and less than or equal to 8 hours; and the second solidifying duration is greater than 0 and less than or equal to 2 hours.

[0055] In this embodiment, the first solidifying temperature is greater than or equal to 40 degrees Celsius and less than or equal to 90 degrees Celsius, and the first solidifying duration is greater than or equal to 0.5 minutes and less than or equal to 3 minutes, which improves the effect of pre-solidification, and neither makes the first ink layer completely solidify nor makes the first ink layer change randomly. The second solidifying temperature is greater than or equal to 70 degrees Celsius and less than or equal to 100 degrees Celsius, and the second solidifying duration is greater than 0 and less than or equal to 2 hours, which makes the solidification of the first ink layer more complete, and realizes the secondary solidification of the first ink layer, and further improves the solidification effect of the first ink layer, so as to form a stable first pattern layer on the film body.

[0056] The first standing temperature is greater than or equal to 18 degrees Celsius and less than or equal to 35 degrees Celsius, and the first standing time is greater than or equal to 1 hour and less than or equal to 8 hours. When the first pattern layer is not completely cured, placing the film body in an environment of 18 degrees Celsius to 35 degrees Celsius for 1 hour to 8 hours will cause the magnetic pigments in the magnetic ink of the first pattern layer to diffuse and rearrange, causing the already formed pattern to be blurred, and the pattern of the second pattern layer to remain in a state of aggregation, thereby achieving a virtual-real hierarchical relationship. Each time the screen printing interval is different, the blurring effect is different. The nth layer continues to be stacked, and the magnetic powder is completely shaped, and screen printing the next layer of magnetic pattern will not cause the magnetic effect of the previous layer to change.

[0057] Specifically, the film body is a polyethylene terephthalate (PET) film.

[0058] A layer of magnetic ink is screen printed on the PET film, and the screen printing mesh is 100 to 300.

[0059] The PET film with the screen printed magnetic ink is placed on the first magnetic plate to form a pattern of the magnetic ink, and then placed in a tunnel furnace for pre-curing, with a curing time of 0.5 to 3 minutes and a curing temperature of 40 to 90 degrees Celsius. After pre-curing, the film is removed from the magnetic plate and placed in an oven for secondary curing, with a secondary curing time of 0 to 2 hours and a curing temperature of 70 to 100 degrees Celsius. After curing, the ink thickness is 5 to 10 microns.

[0060] According to some embodiments of the present application, screen printing and curing the second pattern layer on the film body includes: screen printing the second pattern layer on the first pattern layer; placing the film body on a second magnetic plate; heating the film body and the second magnetic plate at a third curing temperature for a third curing time; separating the film body from the second magnetic plate; and heating the film body at a fourth curing temperature for a fourth curing time, wherein the magnetic lines of the second magnetic plate correspond to the pattern of the second pattern layer, and the arrangement of the magnetic lines of the second magnetic plate is different from the arrangement of the magnetic lines of the first magnetic plate.

[0061] In this embodiment, the second ink layer is screen printed on the first pattern layer; the film body is placed on the second magnetic plate, so that the second ink layer forms a corresponding pattern according to the direction of the magnetic lines on the second magnetic plate; and since the first pattern layer has been cured, the second magnetic plate will not affect the first pattern layer. Heating the film body and the second magnetic plate at a third curing temperature for a third curing time realizes pre-curing of the second ink layer, avoiding changes in the pattern formed by the second ink layer when the film body is removed from the second magnetic plate. Heating the film body at a fourth curing temperature for a fourth curing time realizes secondary curing of the second ink layer, so that a stable second pattern layer is formed on the film body.

[0062] Before the film body and the second magnetic plate are heated at the third curing temperature for the third curing duration, the film body is removed from the second magnetic plate, and the film body is heated at a fourth curing temperature for a fourth curing duration.

[0063] Specifically, as shown in Figure 2 the manufacturing method of the film assembly includes:

[0064] Step 602, screen printing a first pattern layer on the film body;

[0065] Step 604, placing the film body on a first magnetic plate;

[0066] Step 606, heating the film body and the first magnetic plate at a first curing temperature for a first curing duration;

[0067] Step 608, separating the film body from the first magnetic plate;

[0068] Step 610, placing the film body at a first resting temperature for a first resting duration;

[0069] Step 612, heating the film body at a second curing temperature for a second curing duration;

[0070] Step 614, screen printing a second ink layer on the first pattern layer;

[0071] Step 616, placing the film body on a second magnetic plate;

[0072] Step 618, heating the film body and the second magnetic plate at a third curing temperature for a third curing duration;

[0073] Step 620, separating the film body from the second magnetic plate;

[0074] Step 622, heating the film body at a fourth curing temperature for a fourth curing duration.

[0075] According to some embodiments of the present application, the third curing temperature is greater than or equal to 40 degrees Celsius and less than or equal to 90 degrees Celsius, the fourth curing temperature is greater than or equal to 70 degrees Celsius and less than or equal to 100 degrees Celsius, the third curing duration is greater than or equal to 0.5 minutes and less than or equal to 3 minutes, and the fourth curing duration is greater than 0.5 hours and less than or equal to 2 hours.

[0076] In this embodiment, the third solidification temperature is greater than or equal to 40 degrees Celsius and less than or equal to 90 degrees Celsius, and the third solidification time is greater than or equal to 0.5 minutes and less than or equal to 3 minutes, which improves the pre-solidification effect and neither completely solidifies the second ink layer nor causes the second ink layer to change randomly. The fourth solidification temperature is greater than or equal to 70 degrees Celsius and less than or equal to 100 degrees Celsius, and the fourth solidification time is greater than 0.5 hours and less than or equal to 2 hours, which makes the solidification of the second ink layer more complete, thereby realizing secondary solidification of the second ink layer and further improving the solidification effect of the second ink layer to form a stable second pattern layer on the film body.

[0077] Specifically, the second layer of magnetic line phantom ink layer is screen printed on the surface of the first pattern layer, and the screen mesh is 100 to 300 meshes.

[0078] The PET screen printed with the magnetic line phantom ink is placed on the second magnetic plate to form a patterned magnetic line phantom, and then placed in a tunnel furnace for pre-solidification, with a solidification time of 0.5 to 3 minutes and a solidification temperature of 40 to 90 degrees Celsius. After pre-solidification, the film is removed from the magnetic plate and placed in an oven for secondary solidification, with a secondary solidification time of 0.5 to 2 hours and a solidification temperature of 70 to 100 degrees Celsius. After solidification, the thickness of the two ink layers is 15 to 25 microns.

[0079] Specifically, the multi-layer pattern layer can also include a third pattern layer and a fourth pattern layer, and can also include more pattern layers.

[0080] When printing a multi-layer pattern layer on the film body, a first pattern layer can be screen printed on the film body, and the first pattern layer can be provided as a red arc-shaped pattern. After the first pattern layer is solidified and formed, a second pattern layer is screen printed on the first pattern layer, and the second pattern layer can be provided with a yellow arc-shaped pattern. After the second pattern layer is solidified and formed, a third pattern layer is screen printed on the second pattern layer, and the third pattern layer can be provided with a blue arc-shaped pattern. After the third pattern layer is solidified and formed, a fourth pattern layer is screen printed on the third pattern layer, and the fourth pattern layer can be provided with a black arc-shaped pattern. By adjusting the magnetic pole distribution of the magnetic plate used when screen printing each pattern layer, the patterns of the four pattern layers can be crossed, thereby realizing the crossing of different color patterns of the printed pattern and improving the sense of hierarchy of the printed pattern. If the pattern is printed on the same pattern layer, the four color arc-shaped patterns will only be arranged side by side and will not cross.

[0081] Further, when printing the first layer of the pattern layer, place it on the first magnetic plate to cure and form, then print the second layer of the pattern layer, place it on the second magnetic plate to cure and form, and continue to stack n layers of magnetic patterns, n is a natural number of 1, 2, 3, etc., continue to place it on the magnetic plate to cure and form. Through the design of the first magnetic plate, the second magnetic plate, and the nth magnetic plate, a variety of cross and complex patterns can be achieved. When the nth layer of magnetic ink uses different colors of magnetic pigments, the color hierarchy can be achieved, and color superposition can be achieved.

[0082] By adjusting the types of magnetic ink pigments of different layers, ink curing time, and magnetic field distribution of the magnetic plate, printing multiple layers of magnetic patterns can achieve more rich cross, hierarchy, and phantom appearance effects.

[0083] As shown in Figure 3 and Figure 4 , according to some embodiments of the present application, the film assembly 100 is manufactured by the manufacturing method of the film assembly 100 of any of the above technical solutions, the film assembly 100 includes a film body 110 and a multi-layer pattern layer 120; the multi-layer pattern layer 120 is stacked on the film body 110; wherein, as shown in Figure 5 , Figure 6 and Figure 7 , the pattern lines of each layer of the multi-layer pattern layer 120 are orthogonally projected on the film body 110.

[0084] In this embodiment, the film assembly 100 includes a film body 110 and a multi-layer pattern layer 120, the multi-layer pattern layer 120 is stacked on the film body 110, the film body 110 can carry the multi-layer pattern layer 120, the film body 110 printed with the pattern layer 120 can be attached to the shell 200 of the electronic device, thereby making the appearance of the electronic device more beautiful. Since the multi-layer pattern layer 120 is stacked, the multi-layer pattern layer 120 can be printed separately, since the patterns of each layer of the multi-layer pattern layer 120 are different, and the pattern layer 120 is a magnetic pattern layer, printing the multi-layer pattern layer 120 separately can make the printed pattern more rich, and improve the hierarchy of the printed pattern. Since the multi-layer pattern layer 120 can be printed separately, different magnetic plates can be used to print each layer of the pattern layer 120 when printing the pattern layer 120, thereby making the lines of the pattern of the multi-layer pattern layer 120 cross, and the patterns of different colors in the multi-layer pattern layer 120 can also be cross, further improving the hierarchy of the printed pattern layer 120. The lines of the pattern of the multi-layer pattern layer 120 can be cross, and the patterns of different colors in the multi-layer pattern layer 120 can also be cross, which can also reduce the difficulty of printing complex patterns, thereby improving the efficiency of printing the film assembly 100 and reducing the cost of printing the film assembly 100. The multi-layer pattern layer 120 is a magnetic pattern layer, which can also make the pattern layer 120 be printed by magnetic ink, and improve the beauty of the printed pattern.

[0085] Specifically, by designing the pattern of the magnetic plate of the printing pattern layer 120, different effects are applied by stacking different magnetic plates, the magnetic pattern is printed on the film body 110 multiple times, and on a specific magnetic plate, a layer-by-layer pattern effect is gradually formed, and is respectively solidified and shaped, so that a pattern with a cross and multi-level appearance effect can be realized.

[0086] Specifically, the multi-layer pattern layer 120 can be printed by magnetic ink.

[0087] According to some embodiments of the present application, as shown in Figure 3 and Figure 4 , the multi-layer pattern layer 120 includes a first pattern layer 122 and a second pattern layer 124; the first pattern layer 122 is attached to the film body 110; and the second pattern layer 124 is arranged on the side of the first pattern layer 122 away from the film body 110.

[0088] In this embodiment, the multi-layer pattern layer 120 includes a first pattern layer 122 and a second pattern layer 124, which are printed on the film body 110 in turn, so that the first pattern layer 122 and the second pattern layer 124 are superimposed, and the patterns on the first pattern layer 122 and the second pattern layer 124 can overlap or cross, thereby forming a pattern layer 120 with a more stereoscopic effect on the film body 110 relative to a single-layer pattern layer 120, thereby improving the level of the multi-layer pattern layer 120.

[0089] Optionally, the multi-layer pattern layer 120 can also include a third pattern layer 126 and a fourth pattern layer 128, and can also include more pattern layers 120.

[0090] When printing the multi-layer pattern layer 120 on the film body 110, as shown in Figure 5 , Figure 6 and Figure 7 , the first pattern layer 122 can be printed on the film body 110 first, and the first pattern layer 122 can be arranged as a red arc pattern. After the first pattern layer 122 is solidified and shaped, the second pattern layer 124 is printed on the first pattern layer 122, and the second pattern layer 124 can be arranged as a yellow arc pattern. After the second pattern layer 124 is solidified and shaped, the third pattern layer 126 is printed on the second pattern layer 124, and the third pattern layer 126 can be arranged as a blue arc pattern. After the third pattern layer 126 is solidified and shaped, the fourth pattern layer 128 is printed on the third pattern layer 126, and the fourth pattern layer 128 can be arranged as a black arc pattern. By adjusting the magnetic pole distribution of the magnetic plate used when printing each pattern layer 120, the patterns of the four pattern layers 120 can be crossed, thereby realizing the crossing of different color patterns of the printed pattern and improving the level of the printed pattern. As shown in Figure 8 , Figure 9and Figure 10 As shown in FIG. 1, if the four patterns are all printed on the first pattern layer 122, the arc-shaped patterns of the four colors are only arranged side by side and do not cross each other.

[0091] As shown in FIG. 2, the first pattern layer 122 can be printed on the film body 110 by the first magnetic plate 310 first, and then the second pattern layer 124 can be printed on the first pattern layer 122 by the second magnetic plate 320. Figure 11 As shown in FIG. 3, the first pattern layer 122 and the second pattern layer 124 can form a more three-dimensional pattern layer 120. Figure 12 As shown in FIG. 4, the first pattern layer 122 can be printed on the second pattern layer 124 by the first magnetic plate 310 again, and the second pattern layer 124 can be printed on the first pattern layer 122 by the second magnetic plate 320 again. Figure 13 As shown in FIG. 5, the first pattern layer 122 and the second pattern layer 124 can form a more three-dimensional pattern layer 120.
