1. Field of the Invention
The invention generally relates to a workpiece, and more particularly to a workpiece with three-dimensional pattern.
2. Description of Related Art
Currently, electronic devices such as notebook computers, mobile phones, or digital cameras mostly adopt metal material for constituting the exterior. In order to advance the overall aesthetic appearance of electronic devices, various patterns are usually formed on the appealing configuration. Patterns are produced on the surface of metal material frequently by etching metal material with a solvent or by paint-spraying and transfer printing. Nonetheless, the surface treatment technique of the former is complicated and difficult, and the latter is restrained by the chemical property of metal material, such that artistic configuration cannot be produced.
The invention is directed to a workpiece, wherein an adhesive layer having multiple three-dimensional micro patterns is disposed on the workpiece to form three-dimensional visual effect.
An embodiment of the invention provides a workpiece with three-dimensional pattern having a three-dimensional surface and suitable for an electronic device. A multiple three-dimensional micro patterns formed on the three-dimensional surface reflects an environment light to form images with a visual effect. The workpiece with three-dimensional pattern includes a workpiece and an adhesive layer. The adhesive layer is disposed on the workpiece and impressed to form the multiple three-dimensional micro patterns, and the workpiece is punched to form the three-dimensional surface. A first part of the multiple three-dimensional micro patterns on the three-dimensional surface reflects the environment light to form a first reflecting light beam. A second part of the multiple three-dimensional micro patterns on the three-dimensional surface reflects the environment light to form a second reflecting light beam. The images with visual effect includes at least the first reflecting light beam, the second reflecting light beam, and the multiple three-dimensional micro patterns.
In light of the foregoing, in the embodiments of the invention, the adhesive layer is disposed on the workpiece, such that one part of the multiple three-dimensional micro patterns on the three-dimensional surface reflects the environment light to form a first reflecting light beam while another part of the multiple three-dimensional micro patterns on the three-dimensional surface reflects the environment light to form a second reflecting light beam. Through the multiple three-dimensional micro patterns of the adhesive layer, the first reflecting light beam and the second reflecting light beam may have different phases to be counteracted each other or have the same phases to be added together, such that three-dimensional visual effect is formed to advance the aesthetic appearance of the workpiece.
In order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanying figures are described in detail below.
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
In the disposing manner above-mentioned, the adhesive layer 200 is disposed on the workpiece 100, such that one part of the multiple three-dimensional micro patterns on the three-dimensional surface 110 reflects the environment light L1 to form the first reflecting light beam L2 while another part of the multiple three-dimensional micro patterns on the three-dimensional surface 110 reflects the environment light L1 to form a second reflecting light beam L3. Through the multiple three-dimensional micro patterns of the adhesive layer 200, the first reflecting light beam L2 and the second reflecting light beam L3 may have different phases to be counteracted each other or have the same phases to be added together, such that three-dimensional visual effect is formed to advance the aesthetic appearance of the workpiece 100.
For example, the first reflecting light beam L2 is reflected by the adhesive layer 200, and the second reflecting light beam L3 is reflected by the workpiece 100 and refracted by the adhesive layer 200, such that the first reflecting light beam L2 and the second reflecting light beam L3 have different phases to be counteracted each other or have the same phases to be added together.
When a plurality of light beams L1 are respectively reaches different regions of the adhesive layer 200, the multiple three-dimensional micro patterns of the adhesive layer 200 causes different reflecting effects and different refracting effects in different regions of the adhesive layer 200, such that phase variation of one reflecting light beam could be different from phase variation of another reflecting light beam. Thus, counteracting effects of reflecting light beams and adding effects of light beams are different in different regions so that the three-dimensional visual effect above-mentioned is formed.
In the present embodiment, the workpiece 100 is made of, for example, aluminum alloy (5052), stainless steel (430, 304), cold rolling steel (spcc), magnesium alloy (AZ91D, AZ61) or other metal materials suitable for constituting the exterior.
Particularly, the adhesive layer 200 has a plurality of optical micro structures 210 to form the multiple three-dimensional micro patterns. Each of the optical micro structures 210 has a cross-section of rectangle. Each of the optical micro structures 210 has a width W of 20 μm to 500 μm (perfectly 50 μm to 1500 μm) and a height H of 1 μm to 20 μm. (perfectly 5 μm to 12 μm) The adhesive layer 200 has a thickness T of 5 μm to 50 μm (perfectly 10 μm to 20 μm) and a transparency of 5 percent to 100 percent. In other embodiments, each of the optical micro structures 210 can have any other suitable width and any other suitable height, the adhesive layer 200 can have any other suitable thickness and any other suitable transparency, and the present invention is not limited thereto.
In the present embodiment, the workpiece 100 is, for instance, a metal plate, a fiber and metal plate or a carbon-fiber and metal plate. Thus, in the process of producing this workpiece 100, the production efficiency of the workpiece 100 can enhanced by transporting and processing with a roller apparatus.
In this embodiment, the workpiece 100 could be processed using a punching apparatus so as to punch the workpiece 100 from a plate state into a three-dimensional workpiece. Accordingly, the workpiece 100 of the present embodiment first forms the multiple three-dimensional micro patterns by disposing the adhesive layer 200 on the workpiece 100, and the workpiece 100 is then processed by the punching apparatus depending on the configuration required. Consequently, the technical difficulty of forming the multiple three-dimensional micro patterns on the surface of the three-dimensional workpiece is overcome, and the suitability of the workpiece 100 is further increased.
In other embodiments, more color layers with different colors could be applied between the adhesive layer 200 and the primer layer 300, and the present invention is not limited thereto.

In summary, in the aforementioned embodiments of the invention, the adhesive layer is disposed on the workpiece, such that one part of the multiple three-dimensional micro patterns on the three-dimensional surface reflects the environment light to form a first reflecting light beam while another part of the multiple three-dimensional micro patterns on the three-dimensional surface reflects the environment light to form a second reflecting light beam. Through the multiple three-dimensional micro patterns of the adhesive layer, the first reflecting light beam and the second reflecting light beam may have different phases to be counteracted each other or have the same phases to be added together, such that three-dimensional visual effect is formed to advance the aesthetic appearance of the workpiece.
