The design relates to a glass surface having a curvature change design formed on the glass surface by means of chemical ion strengthening means, using a cover for installing the planned design.

  The projection lens installs a hidden design on the lens surface. In particular, in a fine curvature change design, when a light beam irradiates the lens surface, the reflected light beam is subjected to the effect of the curvature change design on the lens surface. Thereby, the light beam causes a subtle convergence or dispersion phenomenon. In this way, it is possible to project a hidden design on the lens surface, form a corresponding clear light design, and give a new sense to the person. Therefore, the above-described technique is suitable for application to the installation of trademarks or decorative designs, and can be applied to the creation of art-like graphic crafts.

  According to historical sources, the oldest projection lens can be found in the Western Han Dynasty. It used a copper mirror to reflect light rays. After reflecting the light beam, a clear light design corresponding to the pattern on the back of the copper mirror can appear. The above-described reflecting mirror effect of the copper mirror uses a precise polishing means to form a fine curvature change design corresponding to the pattern on the back of the copper mirror on the mirror surface. The above-described precision polishing means for copper mirrors is very time consuming and laborious, and since the processing cannot be completed without accurate and advanced operation techniques, the projection lens has not been widely used.

  Patent Document 1 discloses a projection lens manufacturing method having the same effect as described above. That is, after the reflector molding, a design with a pattern is cut with a laser on another surface on the reflector mirror surface side, and the reflector mirror surface side forms a corresponding curvature change by using this design. be able to. Thus, an effect similar to the effect produced by polishing the mirror surface side as described above is achieved. However, this method similarly requires two-step processing, and the cost is increased because the design is cut using a laser, and the cost performance is low.

  Patent Document 2 discloses a projection lens manufactured by injection molding. It forms an uneven structure with a pattern design on one side of a plastic body with a thickness of 3 mm or less. Thereby, the other side corresponds to this concavo-convex structure, and a curvature change surface having a slight concavo-convex structure is formed, and a light reflection layer is provided on one side of this curvature change surface. Therefore, it is not necessary to perform any polishing or cutting on the plastic body, and a projection mirror surface having a corresponding design is directly formed on the back surface. This technique is mainly applied to thin plate type injection molding or casting, and is not applied to relatively thick plate or non-flat type objects. In addition, this technique cannot be applied to a plate body such as glass, which requires both the upper and lower surfaces to be flat.

  In order to describe in detail the technical contents, structural features, and objects to be achieved of the present invention, examples will be described below in combination with the drawings.

As shown in the figure, the method of manufacturing a glass surface provided with the curvature change design provided by the embodiment of the present invention includes the following steps. First, the glass 1 is provided. In this embodiment, the glass 1 is a sodium calcium silicate glass plate whose upper and lower surfaces are both flat, and the upper surface is a smooth surface 12 having a surface roughness (Ra) of about 0.08 μm. It is. Next, the cover 2 is installed on the smooth surface 12. The cover 2 adheres tightly on the smooth surface 12. As shown in FIGS. 1 and 2, in the cover 2, a number of hollow portions 21 are installed and arranged to form a planned design P. The cross-sectional shape of each hollow portion 21 is an irregular geometric surface, but the cross-sectional area is at least 0.2 mm ² or more, so that a chemical ion strengthening liquid described later can smoothly flow therethrough. The cover 2 is made of a silicon material having acid corrosion resistance and having a heat resistant temperature of 380 ° C. or higher. In the present embodiment, the cover 2 uses stencil printing technical means to print molten silicon on the smooth surface 12 to form a cover design. After the silicon material is placed on the glass surface, the glass 1 is preferably placed in a hot air oven and baked at a low temperature. Subsequently, the temperature is gradually lowered to room temperature (about 25 ° C.), the standardization of the cover 2 is promoted, and the adhesion force to the smooth surface 12 of the cover 2 is improved.

Subsequently, a chemical ion strengthening process is performed on the glass smooth surface 12, and the glass smooth surface 12 covered with the cover 2 is immersed in a salt bath (not shown). The salt bath contains a melt strengthening liquid having a temperature range of 380 ° C to 450 ° C. In this embodiment, a potassium nitrate (KNO ₃ ) solution is used as the strengthening solution, and thereby chemical ion strengthening is performed on the above-described sodium calcium silicate glass plate. During the strengthening process, the smooth surface 12 is located in a widely exposed surface area of the cover 2 hollow portion 21 area and performs an ion exchange treatment with the strengthening liquid. Thereby, sodium ions (Na ⁺ ) in the glass surface layer are replaced with equivalent potassium ions (K ⁺ ) in the strengthening solution. Since the large ions (potassium ions, K ⁺ ) in the strengthening solution are replaced with small ions (sodium ions, Na ⁺ ) on the glass, a pressure layer is formed on the glass surface in the hollow portion 21 area. . The other areas shielded by the cover 2 of the smooth surface 12 are not subjected to ion exchange treatment, so that no pressure layer is formed on the surface. Therefore, a number of pressure zones 13 corresponding to the hollow portion 21 are formed on the smooth surface 12 through the strengthening process described above (see FIGS. 3 and 4).

  Usually, the time for immersing the glass in the reinforcing liquid is about 0.5 hours to about 7 hours. The pressure range of tempered glass produced by ion exchange treatment is about 50 to about 800 MPa. As the skilled person in this section knows, there are many parameters for ion exchange treatment, such as the salt bath components and temperature, the soaking time, the number of glasses immersed in the salt bath, and other steps such as annealing. This includes, but is not limited to, using a salt bath, cleaning, and the like. These are usually used to set the tempering parameters based on predispositions such as glass composition, required pressure layer depth, and surface pressure values.

  Finally, a peeling process is performed to peel off and remove the cover 2 on the smooth surface 12 of the glass 1. Thereby, a pressure pattern on the surface of the glass 1 appears. The implementation method is as follows. First, a release agent or a light-weight polish is sprayed on the part where the cover 2 on the surface of the glass 1 is installed. Thereby, the cover 2 is smoothly peeled off from the surface of the glass 1 and removed. Next, the glass 1 is washed with a washing liquid (eg, fresh water).

  If the above-described processing steps are completed, a glass surface having a curvature change design can be obtained. On the smooth surface 12 of the glass 1 is provided a design in which a number of pressure zones 13 are arranged and composed. Usually, the pressure value in the pressure zone 13 is at least 50 MPa. Due to the pressure action, a slightly projecting variable phenomenon occurs on the inner surface of the pressure zone 13. Therefore, the curvature change design P ′ corresponding to the hidden figure of the planned design P described above can be formed on the smooth surface 12 of the glass 1. When the light beam is irradiated on the design, the reflected light beam is subjected to the action of the curvature change design P ′ on the smooth surface 12. As a result, the rays converge or cause a dispersion phenomenon. Thus, a clear light design F corresponding to the planned design P is projected and appears (see FIGS. 5 and 7).

  In another embodiment of the present invention, the light reflecting layer 3 can be further added on the smooth surface 12 of the glass 1 provided with the above-described curvature change pattern P '. Preferably, the light reflecting layer 3 is a metal thin film layer having a surface roughness (Ra) of about 0.8 μm and a layer thickness of about 80 μm. After the thin film is installed, a corresponding curvature change pattern P ′ is formed on the surface of the light reflecting layer 3 (see FIG. 6). Usually, the light reflecting layer 3 of the metal thin film is applied by means such as coating, spraying, electroplating, sputtering, chemical vapor deposition (CVD), physical vapor deposition (PVD), thin film surface mounting technology (SMT), etc. Installed using.

All equivalent applications based on the spirit of the present invention, conversion of parts (structure), replacement, and increase / decrease in quantity are included in the protection scope of the present invention.
