[0023] To make the objectives, technical solutions and advantages of the present invention clearer, the following will, in conjunction with the accompanying drawings in the embodiments of the present invention, fully describe the technical solutions of the present invention through specific implementation manners. Apparently, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Figure 1 The flowchart of a method for transferring a holographic image provided by an embodiment of the present invention mainly includes the following steps:

[0025] S101. Provide a holographic image layer, where the holographic image layer at least includes a transfer layer containing a holographic image that can be peeled off from a substrate film.

[0026] Among them, the transfer layer containing a holographic image that can be peeled off from a substrate film includes a holographic image formed after the photosensitive material is exposed to light, or a holographic image made by a stamping method. The specific material of the transfer layer containing a holographic image that can be peeled off from a substrate film is not specifically limited in this embodiment. For example, it can be a film layer formed by a photosensitive material such as a photopolymer or silver salt, or a coating suitable for the stamping method. Specifically, the transfer layer containing a holographic image that can be peeled off from a substrate film includes a holographic image, which is a pattern recording light field information and can have a three-dimensional sense.

[0027] S102. Provide an adhesive layer and laminate the transfer layer containing a holographic image that can be peeled off from a substrate film on the first surface of the adhesive layer. The adhesive layer is a solid film structure with double-sided adhesiveness.

[0028] Specifically, the adhesive layer is a solid film structure with double-sided adhesiveness. For example, it can be a photosensitive cured double-sided adhesive. Heating is not required, and a laminating machine can directly bond the transfer layer containing a holographic image that can be peeled off from a substrate film to the first surface of the adhesive layer. Moreover, during the process of laminating the transfer layer containing a holographic image that can be peeled off from a substrate film on the first surface of the adhesive layer, no chemical reaction occurs between the transfer layer containing a holographic image that can be peeled off from a substrate film and the adhesive layer. In this way, it is ensured that the holographic image in the transfer layer containing a holographic image that can be peeled off from a substrate film will not be damaged.

[0029] S103. Die-cut the laminated holographic image layer and adhesive layer according to the shape of a preset holographic image.

[0030] Among them, the shape of the preset holographic image refers to the actual shape of the holographic image. For example, it can be the shape of an animal, such as the body shape of a puppy, or a circle or a rectangle. This embodiment does not make specific limitations on this.

[0031] Specifically, a die cutter is used to die cut the holographic image layer and the adhesive layer according to the shape of the preset holographic image, so as to obtain the die-cut holographic image structure.

[0032] It should be noted that during the actual transfer process, when the actual size of the holographic image is very large or batch transfer is required, it may not be necessary to die cut the adhered holographic image, which can improve the transfer rate. Therefore, it can be determined whether to die cut the adhered holographic image according to the actual situation, and this embodiment does not make special limitations on this.

[0033] S104. Provide a substrate and laminate the second surface of the die-cut adhesive layer on the substrate.

[0034] Among them, the substrate can be made of materials such as paper, glass, acrylic, or metal, and can be a curved surface structure or a flat surface structure. This embodiment does not make special limitations on this.

[0035] Specifically, a labeling machine is used to bond the second surface of the adhesive layer in the die-cut holographic image structure obtained in the above step S103 to the substrate, that is, to cover and bond the second surface of the adhesive layer in the die-cut holographic image structure on the substrate, so as to obtain the transferred holographic image, which has a high bonding degree and the holographic image is clear and intact.

[0036] In the embodiment of the present invention, by providing a holographic image layer and a solid film-like adhesive layer, the holographic image layer at least includes a transfer layer containing a holographic image that can be peeled off from the substrate film. The transfer layer containing the holographic image that can be peeled off from the substrate film is laminated on the first surface of the adhesive layer, and then the adhered holographic image layer and the adhesive layer are die cut according to the shape of the preset holographic image, and the second surface of the die-cut adhesive layer is laminated on the substrate, so as to complete the transfer of the holographic image and obtain a three-dimensional hologram with a high bonding degree and a clear and intact image.

[0037] Figure 2 It is a schematic structural diagram of a holographic image layer provided by an embodiment of the present invention. As Figure 2 shown, optionally, the holographic image layer 1 further includes a release layer 12 and a first film layer 11; the release layer 12 is located on the side of the transfer layer 13 containing the holographic image that is far from the adhesive layer; the first film layer 11 is located on the side of the release layer 12 that is far from the transfer layer 13 containing the holographic image.

[0038] Among them, the release layer 12 is used to isolate and protect the transfer layer 13 containing the holographic image that can be peeled off from the substrate film. The first film layer 11 is used to protect the holographic image from being damaged during the transfer process. It can be a polyethylene terephthalate (PET) film or a polycarbonate (PC) film, which is not limited in this embodiment. Specifically, the release layer 12 and the first film layer 11 are sequentially stacked on the transfer layer 13 containing the holographic image that can be peeled off from the substrate film. The binding force between the release layer 12 and the transfer layer 13 containing the holographic image that can be peeled off from the substrate film is less than the binding force between the second surface of the adhesive layer and the substrate material. In this way, when the first film layer 11 and the transfer layer 13 containing the holographic image that can be peeled off from the substrate film are peeled off, due to the stable release force exhibited by the release layer 12, the first film layer 11 can be easily removed to ensure that the holographic image in the transfer layer 13 containing the holographic image that can be peeled off from the substrate film is not damaged.

[0039] Figure 3 FIG. is a schematic structural diagram of an adhesive layer provided by an embodiment of the present invention. Optionally, the adhesive layer 2 includes a first protective layer 21, an adhesive layer 22, and a second protective layer 23 stacked in sequence. The surface of the adhesive layer 22 facing the first protective layer 21 is the first surface of the adhesive layer 2, and the surface of the adhesive layer 22 facing the second protective layer 23 is the second surface of the adhesive layer 2; before laminating the transfer layer 13 containing the holographic image that can be peeled off from the substrate film on the first surface of the adhesive layer 2, it further includes: removing the first protective layer 21 of the adhesive layer 2. Figure 4 FIG. is a flowchart of another method for transferring a holographic image provided by an embodiment of the present invention, in combination with Figure 2 、 Figure 3 and Figure 4 shown, mainly including the following steps:

[0040] S401. Provide a holographic image layer, and the holographic image layer at least includes a transfer layer containing a holographic image that can be peeled off from a substrate film.

[0041] S402. Provide an adhesive layer and remove the first protective layer of the adhesive layer.

[0042] Specifically, the first protective layer of the adhesive layer is used to protect the first surface of the adhesive layer from having strong adhesive force and being damaged. In order to bond the first surface with adhesive property on the adhesive layer to the transfer layer containing the holographic image that can be peeled off from the substrate film, the first protective layer needs to be removed. Among them, the first protective layer can be paper, cloth, or plastic film, etc., which is not specifically limited in this embodiment.

[0043] S403. Laminate a transfer layer containing a holographic image that can be peeled off from a base film onto the first surface of the adhesive layer, where the adhesive layer is a solid film structure with double-sided adhesiveness.

[0044] S404. Die-cut the adhered holographic image layer and adhesive layer according to the shape of the preset holographic image.

[0045] Optionally, die-cut the holographic image layer and the glue layer while retaining the second protective layer.

[0046] Specifically, the second protective layer can be paper, cloth, or plastic film, etc., which is used to protect the adhesiveness of the second surface of the adhesive layer from being damaged. During the process of die-cutting the holographic image layer and the adhesive layer according to the shape of the preset holographic image using a die-cutting machine, only the holographic image layer and the glue layer are die-cut, and the second protective layer of the adhesive layer is not die-cut. In this way, it is ensured that the die-cut holographic image structures are all connected together through the second protective layer. Especially for larger-sized holographic image structures, for the convenience of storage, they can also be folded or rolled into a shaft through the second protective layer. In this way, it is ensured that the die-cut holographic image structures are complete and not damaged.

[0047] S405. Remove the second protective layer.

[0048] Specifically, the second protective layer has no adhesiveness and is used to protect the adhesiveness of the second surface of the adhesive layer from being damaged. Therefore, before pasting the die-cut holographic image structure onto the base, the second protective layer needs to be removed.

[0049] S406. Provide a base and laminate the second surface of the die-cut adhesive layer onto the base.

[0050] It should be noted that the adhesive layers on the first surface and the second surface of the glue layer can also be made of different materials to ensure that the adhesive layer is suitable for various different materials of the base. Specifically, the glue layer includes a first adhesive layer, a carrier layer, and a second adhesive layer stacked in sequence. The first adhesive layer corresponds to the first surface of the adhesive layer, and the second adhesive layer corresponds to the second surface of the adhesive layer. Among them, the first adhesive layer is a common solid glue or a solid photosensitive glue, the second adhesive layer is a solid photosensitive glue, and the carrier layer is a film structure, such as a PET film, which is used to combine two different solid glues to form a firm glue layer. In this way, it is ensured that the glue layer can adhere to any material of the base without damaging the base.

[0051] In this embodiment, by providing that the adhesive layer has a first protective layer, an adhesive layer, and a second protective layer, the first protective layer and the second protective layer protect the adhesive layer of the adhesive layer from being damaged and have strong adhesiveness. At the same time, before laminating the transfer layer containing the holographic image that can be peeled off from the base film on the first surface of the adhesive layer, the first protective layer is removed. When die-cutting the holographic image layer and the adhesive layer, the second protective layer is retained to facilitate the integrity of the relatively large-sized holographic image structure. Before laminating the second surface of the die-cut adhesive layer on the base, the second protective layer is removed. In this way, during the holographic image transfer process, a three-dimensional holographic image with high adhesion and complete and clear clarity is formed.

[0052] Figure 5 The flowchart of another holographic image transfer method provided by an embodiment of the present invention is as Figure 5 shown, and mainly includes the following steps:

[0053] S501. Provide a holographic image layer, and the holographic image layer at least includes a transfer layer containing a holographic image that can be peeled off from a base film.

[0054] S502. Provide an adhesive layer, and laminate the transfer layer containing a holographic image that can be peeled off from a base film on the first surface of the adhesive layer. The adhesive layer is a solid film structure.

[0055] S503. Die-cut the laminated holographic image layer and adhesive layer according to the shape of a preset holographic image.

[0056] S504. Provide a base, and laminate the second surface of the die-cut adhesive layer on the base.

[0057] S505. Perform light curing on the die-cut structure.

[0058] Specifically, a light curing machine is used to simultaneously irradiate the die-cut holographic image structure and the base with light, so that the adhesiveness between the adhesive layer and the transfer layer containing a holographic image that can be peeled off from the base film, and between the adhesive layer and the base is more firm and will not fall off.

[0059] Optionally, performing light curing on the die-cut structure includes: irradiating the die-cut structure with adapted light, and the irradiation time length t ≥ the unit area light energy required for curing ÷ the illuminance of the curing position.

[0060] Specifically, the adhesive layer of the glue layer is a photosensitive material. To further enhance the adhesiveness of the glue layer, an adapted light is used to irradiate the die-cut structure. Considering the differences in the thickness of the glue layer and the special synthetic composition, the irradiation time length t is set such that t ≥ the light energy per unit area required for curing ÷ the illuminance at the curing position. For example, preferably, the holographic image is irradiated with the adapted light for 1 minute. In this way, the viscosity and hardness of the glue layer are ensured to reach the best, and the holographic image will not fall off.

[0061] It should be noted that the specific type of the adapted light can be matched according to the material of the glue layer of the adhesive layer. For example, it can be ultraviolet light, visible light, or infrared light. This embodiment does not make special limitations on this. Exemplarily, when the glue layer is sensitive to ultraviolet light, the adapted light can be ultraviolet light, so as to ensure the best photo-curing effect.

[0062] Figure 6 This is a flowchart of another method for transferring a holographic image provided by an embodiment of the present invention. As Figure 6 shown, it mainly includes the following steps:

[0063] S601. Provide a holographic image layer, and the holographic image layer at least includes a transfer layer containing a holographic image that can be peeled off from a base film.

[0064] S602. Provide an adhesive layer, and laminate the transfer layer containing the holographic image that can be peeled off from the base film on the first surface of the adhesive layer. The adhesive layer is a solid film structure.

[0065] S603. Die-cut the laminated holographic image layer and adhesive layer according to the shape of the preset holographic image.

[0066] S604. Provide a base, and laminate the second surface of the die-cut adhesive layer on the base.

[0067] S605. Perform light curing on the die-cut structure.

[0068] S606. Remove the first thin film layer of the holographic image layer and perform overcoating protection on the holographic image.

[0069] Specifically, the first thin film layer has a certain thickness, and under the action of the release layer, the first thin film layer is easily peeled off. To reduce the thickness of the holographic image layer, further, the first thin film layer of the holographic image layer is removed, and an overcoating protection is performed on the holographic image by using a light curing machine. This can not only achieve the "beautification" effect but also protect the holographic image in the transfer layer containing the holographic image that can be peeled off from the base film from being scratched and damaged. It should be noted that the overcoating protection can adopt an adapted light overcoating process, such as ultraviolet overcoating varnish. This embodiment does not make special limitations on this.

[0070] Optionally, after removing the first thin film layer of the holographic image layer, a cold laminating film can be used to protect the holographic image.

[0071] Based on the above embodiments, next, taking the actual transfer process as the standard, the transfer method of the holographic image will be described in detail. Specifically, Figure 7 As shown in the flowchart of an actual transfer process of a holographic image provided by an embodiment of the present invention, Figure 7 as shown, the specific implementation process mainly includes the following steps:

[0072] S701. Provide a holographic image layer, where the holographic image layer at least includes a transfer layer containing a holographic image that can be peeled off from a substrate film.

[0074] S702. Provide an adhesive layer and remove the first protective layer of the adhesive layer.

[0075] As Figure 9 shown, the adhesive layer 2 includes a first protective layer 21, a solid photosensitive adhesive layer 22, and a second protective layer 23, which are stacked in sequence. The surface of the solid photosensitive adhesive layer 22 facing the first protective layer 21 is the first surface of the adhesive layer 2, and the surface of the solid photosensitive adhesive layer 22 facing the second protective layer 23 is the second surface of the adhesive layer 2.

[0076] S703. Laminate the transfer layer containing the holographic image that can be peeled off from the substrate film onto the first surface of the adhesive layer.

[0077] As Figure 10 shown, a laminating machine is used to laminate the transfer layer 13 containing the holographic image that can be peeled off from the substrate film onto the first surface of the adhesive layer 2.

[0078] S704. Die-cut the laminated holographic image layer and adhesive layer according to the shape of the preset holographic image.

[0079] As Figure 11 shown, the holographic image layer 1 and the solid photosensitive adhesive layer 22 are die-cut to obtain a square-structured holographic image, and the second protective layer 23 is retained.

[0080] S705. Remove the second protective layer.

[0081] As Figure 12 shown, the second protective layer 23 of the adhesive layer 2 is removed from the die-cut holographic image structure.

[0082] S706. Provide a substrate and laminate the second surface of the die-cut adhesive layer onto the substrate.

[0083] As shown Figure 13 in FIG. 3, the substrate 3 is a very thin paper sheet, and the die-cut holographic image structure is laminated on the substrate 3.

[0084] S707. Light-cure the die-cut structure.

[0085] As shown Figure 14 in FIG. 4, use a suitable light lamp for 1 minute of light curing.

[0086] S708. Remove the first thin film layer of the holographic image layer and apply varnish protection to the holographic image.

[0087] As shown Figure 15 in FIG. 5, apply a layer of suitable light varnish on the holographic image structure, and use a suitable light lamp for light curing to form a bright varnish protection film 4 to protect the holographic image from being damaged.

The laminating machine 101 is used to laminate the transfer layer containing the holographic image that can be peeled off from the substrate film on the first surface of the adhesive layer; a die-cutting machine 102 for die-cutting the laminated holographic image layer and adhesive layer according to the shape of a preset holographic image; a labeling machine 103 for laminating the second surface of the die-cut adhesive layer on the substrate.

[0089] Specifically, the transfer process system further includes a conveying device 104, which is respectively connected between the laminating machine 101 and the die-cutting machine 102, and between the die-cutting machine 102 and the labeling machine 103. The conveying device 104 is used to convey the holographic image structure bonded in the laminating machine 101 to the die-cutting machine 102. Then, the die-cutting machine 102 die-cuts the laminated holographic image layer and adhesive layer according to the shape of the preset holographic image. Then, the conveying device 104 conveys the die-cut holographic image structure to the labeling machine 103. Then, the labeling machine 103 laminates the second surface of the die-cut adhesive layer on the substrate, thus completing the transfer of the holographic image and obtaining a three-dimensional hologram with high adhesion and clear and intact image.

[0090] In an embodiment of the present invention, a laminating machine is provided to laminate a transfer layer containing a holographic image, which can be peeled off from a base film, on a first surface of an adhesive layer. A die-cutting machine die-cuts the laminated holographic image layer and the adhesive layer according to the shape of a preset holographic image. A labeling machine laminates a second surface of the die-cut adhesive layer on a base, thereby realizing the transfer of the holographic image. During the transfer process, the holographic image will not be damaged at all. After the transfer is completed, a three-dimensional holographic image with high adhesion and clear and intact image is obtained.

As Figure 17 shown, optionally, the transfer system further includes a light curing machine 105, and the light curing machine 105 is configured to perform light curing on the die-cut structure.

[0095] Specifically, the light curing machine 105 is connected to the labeling machine through a conveying device. After the labeling machine completes laminating the second surface of the die-cut adhesive layer on the base, the conveying device 104 conveys the adhered holographic image structure to the light curing machine 105, and the light curing machine 105 performs light curing on the die-cut structure to further enhance the viscosity of the photosensitive curing adhesive layer and ensure that the adhesion between the photosensitive curing adhesive layer and the transfer layer containing the holographic image that can be peeled off from the base film and the base is more firm and not easy to fall off.
