Secondly, the practice of _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Recently, the test method has been improved, the wire-making process has been repaired, and the roller has been smashed on the roller. The lining is produced by the roller yarn UV glue and the fine-leaf coil material. This production method has some limitations. For example, the substrate must be UV-transparent, and the surface texture is exposed, which is limited in other product applications. In addition, the conventional cylindrical lens utilizes a platenpress or injection molding method, and its output speed, precision, and size are limited. Recently, a roll-to-roll UV curing molding method has been used, which solves the above problems but is limited to the use of a flexible material. For the sheet, the sheet-type production is carried out by roll-pressing after bonding with the master, but the output speed is lowered. For large-area production, it is easy to have the release problem and it is difficult to handle and affect the production speed and Yield. For products with precise precision requirements, the shrinkage change of UV glue when cured is related to the geometry of 201022048, which is also a place where subtle control is required.

It can make the product more flexible in application, improve the texture of the bumps, and the oil stains that are contacted fill the concave and convex grooves, causing the optical path difference matching to disappear, thereby losing the holographic effect. 1A is a diagram showing a method for producing a flat texture structure of a flat texture structure according to an embodiment of the present invention. The method for producing a Pingcheng road structure uses a combination of two structures to achieve a visual effect. Reminder. As shown in the figure, the texture substrate 10 includes a first substrate 1〇1 having a texture structure 102 and a first resin layer 103 on a surface of the texture structure 102 to planarize the texture structure 1〇2. In one embodiment, the texture substrate 10 is a hologram master, the first substrate 〇1 is a nickel plate, the texture structure 102 is a grain shape, and the first resin layer 〇3 has a first refractive index UV glue. . Secondly, the carrier substrate 20 comprises a second substrate 201, such as polymethyl methacrylate, polyethylene fiber, polyethylene terephthalate, polyethylene terephthalate or polycarbonate resin. A second resin layer 202 is on a surface of the second substrate 201. In an embodiment, the second substrate 201 can be a flexible material or a sheet material, transparent, translucent or opaque optical. The second resin layer 202 has the same first refractive index as the first resin layer 1〇3 201022048, and is preferably also _uv glue. It is to be noted that the refractive index of the second substrate can be the same as the first refractive index, for example, the second substrate 201 is a glass substrate having a refractive index of I·5, and the second resin layer 202 is a (four) 折射率 refractive index ^, Such a second resin layer 202 may fill the scratches that may exist on the second substrate 201 to repair the surface of the second base 201. In the present invention, before the texture substrate 1 is contacted and cured by the first resin layer (10) and the second layer 202 of the carrier substrate 2, the first resin layer 103 on the texture substrate ι is required before bonding. The first curing, for example, in the w curing mode, generally causes the surface of the first resin layer 103 to shrink, but the shrinkage of the first resin layer 1〇3 is on the free surface, and the texture structure 1〇2 There is a distance so that the textured structure 102 is less susceptible to curing shrinkage, thus ensuring the spacing and depth originally required by the escape structure 102. Next, as shown in FIG. 1B, after the grain substrate 1 is in contact with the carrier substrate 2, the first substrate m is removed, and the texture pattern 104 is formed on the surface of the first resin layer (10) away from the carrier substrate 2'. 104 is transferred to the carrier substrate 2 to prevent the surface of the texture pattern 104 from being damaged by the touch or external force of the user, and the third resin layer 1〇5 is formed on the surface of the texture pattern 104 to be flattened. The second resin layer 1〇5 to be described in the protective grain pattern 104 is formed by a claw rubber having a second refractive index different from the first refractive index of the first resin layer (10), thus forming a fold A two-layer structure formed by two transparent materials with different Φ radiances. When the light passes through the two material layers, the structure will produce geometric optics according to its structural modeling properties, and the diffracted optical effect will be generated to produce the visual effect of the design. 2A is a side view of a device for fabricating a flat grain structure in accordance with an embodiment of the present invention. The device for fabricating the flat texture structure comprises a transport module 3 (n, a rolling module 302 is placed on a first side of the transport module 301). A first module 3 is placed in the rolling module 302 away from the transport module 302. One side of the module 3〇1, a second still module 3〇4 are placed on the second side of the wheeling module 301, and a first material loading die is placed on the rolling module 302. In the present embodiment, the rolling module 3〇2 is a roller having a holographic pattern engraving surface that can be rotated relative to the fixed axis. When the rolling module rotates, the surface is first loaded. The module 3G5 is inkjet inkjet inkjet inkjet inkjet module 302. The first material on the line curing module 3〇2. A carrier 30 is transported by the transport module 301 to approach the rolling module 302, and the carrier 30 is firstly passed through a second side toward the first side of the transport. The material t-module 312 is used to disperse or coat the second material 32 on a surface of the carrier 30. The second material loading module 312 will be second with the third material. The material 32 is dispersed or coated on the carrier sheet. Then, the surface is completely covered with the second material 32. The sheet 3g is passed through the rolling module 302 which is fully or selectively attached with the first material. ❿ 参~t the carrier sheet 3 of the first material 32 The rolling module 3〇2 with the first material is connected to: at the position with it:: 'the: υν module 3〇4 is solidified by linear light, and the full fine case (four)-(four) 34 is formed with The carrier of the second material 32 is as illustrated. The second uv module 304 is formed by placing a -UV wire into a drum, and is made of a quartz material. The energy can be t connected to the first material 34. Secondly, the rolling module 302 can provide a bonding force of the material-material 34. Thereafter, the carrier sheet 3 of the first material material 32 having the holographic pattern passes through the third The material loading module is not to disperse or apply the material 36 to the carrier board, and the coffin mnuv module 306 is cured by the line light irradiation method. In the examples of li and MH, the first, second and third materials are respectively a layer of a refractive index of ···, but the invention is not limited to the above, and may be the first The refractive index of the second material is the same but the third material is different. The device side of the fine-grained structure is at a specific position on the carrier plate 3, that is, the carrier plate 3 is formed to be full == surface selective attachment The carrier 30 having the second material 32 passes through the movable module 3〇2. At this time, the position of the second material 32 on the carrier 3 is adhered to the first material 34 on the rolling module 302. A material Μ covers 8 201022048 and the area of each of the second materials 32 dispersed is distributed, so that the holographic pattern can be formed at a position where the carrier 3 is selectively selected. As for the excess or residual first material on the rolling module 3〇2, the cleaning module 4〇1 may be disposed at an appropriate position adjacent to the rolling module 302 to remove excess or residual first material. Secondly, in order to avoid 1; the line light of the light source illuminates the deterioration drum, the second UV module 304 provides a lower line light energy, which may make the second material 32 fit the first material 34 but does not reach a certain level. The dryness is such that after the second UV module 304 is passed, an auxiliary UV module 402 can be further added to further dry the first material 34 on the carrier 30. It should be noted that the above embodiment can also be used to make a full-image pattern on a non-transparent carrier board, for example, to create a holographic pattern on a part of a fabric, which is formed in two stages, and the first stage is as shown in FIG. 2A. Said, the transparent substrate is chosen 'but no dispersion or coating of the third material % is performed. In the second stage, the opaque carrier plate is used, and the first material is no longer applied on the rolling module 3〇2, but the carrier plate with the first material 34 formed on the surface of the first-stage transparent substrate is placed in the rolling die. On the group 302, the opaque flexible carrier is coated with the second material 32 and then rolled into the underside of the rolling module 302 to fit the two. At this time, the uv module can be cured by a transparent substrate, such as a 304 module, and then the transparent carrier in the first stage can be removed by using a winding material to obtain an opaque flexible product having a holographic pattern. The double-layer refractive index structure and the manufacturing apparatus disclosed in the above embodiments of the present invention can solve the problem of the metal layer and the injection plastic when the metal material and the carrier plate are subjected to the in-film emission process when the omnidirectional pattern is expressed by the conventional metal layer. In the case of pseudo-adhesion, the holographic pattern is expressed by the difference in refractive index of the material, avoiding the problem of false adhesion of the metal plating and the injection plastic. Second, the two-layer refractive index structure also planarizes the hologram pattern surface to further protect the holographic pattern to prevent the holographic pattern from detracting from its effects due to external forces or contamination. Furthermore, the apparatus for fabricating a flat grain structure can produce a structure having a texture from a diffraction to a geometric optical level, which is placed in a transparent drum using a light source, and the opacity limitation of the substrate can be avoided, and the present invention The apparatus for fabricating a flat texture structure disclosed in the above embodiments solves the production speed, the precision of controlling the curing shrinkage, the release problem, and the like, so that a large-area product is also feasible, and the material is not necessarily limited to the flexible material, and the surface of the double-layer structure is Flattening can also be done together.
