Description

Optical lens device with functional film and its manufacturing method

The present invention relates to an optical lens device with a functional film and a manufacturing method thereof; in particular, to an optical lens device with a corona-treated surface bonded with a functional film and a manufacturing method thereof.

Regarding the multifunctional optical lens device for learning tools with anti-fog function and its manufacturing method, for example: US Patent Publication No. US-10259744 "PROCESS FOR PRODUCING AN OPTICAL GLASS WITH AN ANTI-FOG COATING" invention patent, which discloses a multifunctional optical lens with anti-fog function and its manufacturing method.

FIG. 1 shows a schematic diagram of the structure of the multifunctional optical lens device for playing equipment with anti-fog function in U.S. Patent Publication No. US-10259744. Referring to FIG. 1, the multifunctional optical lens with anti-fog function in the aforementioned patent No. US-10259744 includes a lens body, a front lens surface, a front surface anti-fog layer and a rear lens surface, and the front surface anti-fog layer is an anti-fog coating layer, and the front surface anti-fog layer is simply a hydrophilic coating layer with Si-C bonds.

Please refer to FIG. 1 again. In terms of structure, the front surface antifogging layer of the aforementioned patent No. US-10259744 is formed on the front lens surface of the lens body to reduce or minimize the contact angle of water droplets attached to the front surface antifogging layer and prevent clouding from occurring on the front lens surface of the lens body.

However, the aforementioned patent No. US-10259744 does not have any corona-treated rear lens surface or front lens surface on the rear lens surface of the lens body, so the rear lens surface (e.g., surfaces with various curvatures or spherical surfaces) or front lens surface of the lens body often leads to various disadvantages that it is difficult to accurately adhere the functional film layer or the functional film.

Another commonly used anti-fog optical lens device, for example: the invention patent of the Republic of China Patent Publication No. TW-I754919, "Multifunctional anti-fog optical lens device", discloses a multifunctional anti-fog optical lens device. The multifunctional anti-fog optical lens device includes an optical substrate layer, a functional optical layer and an anti-fog layer, and a first front surface and a second rear surface are arranged on the optical substrate layer.

As mentioned above, the functional optical layer of the aforementioned patent No. TW-I754919 is formed on the second rear surface of the optical substrate layer, and the functional optical layer is used to provide an optical functionality on the second rear surface of the optical substrate layer. The antifogging layer is formed on the second rear surface of the optical substrate layer, and the antifogging layer is used to provide an antifogging property on the second rear surface of the optical substrate layer, so that the antifogging layer on the second rear surface of the optical substrate layer can prevent fogging due to various factors.

However, although the antifogging layer of the aforementioned patent No. TW-I754919 is formed on the second rear surface of the optical substrate layer to prevent fogging caused by various factors, it does not disclose how to simplify the antifogging layer formed on the second rear surface of the optical substrate layer in terms of manufacturing method to reduce the complexity of the overall manufacturing process.

Another commonly used anti-fog optical lens device and its manufacturing method, for example: the invention patent of "Manufacturing method of anti-fog lens and anti-fog lens" of the Republic of China Patent Publication No. TW-I588516, which discloses an anti-fog lens. The anti-fog lens comprises a lens, a PC material layer, a PC film and an anti-fog film, and the PC film and the anti-fog film are first bonded to each other with an optical glue to form a composite PC film and anti-fog film assembly, and then the lens and the composite PC film and anti-fog film assembly are injection molded with a PC material to form a cured molded body.

However, the solidified molded body of the aforementioned patent No. TW-I588516 includes the lens, PC material layer, PC film and anti-fog film, that is, it forms a multi-layer solidified molded body, and its manufacturing method requires optical adhesive bonding process and injection molding process to be performed separately, so it not only has the disadvantage of complicated manufacturing process, but also has the disadvantage of complicated overall structure.

Another commonly used anti-fog optical lens device and its manufacturing method, for example: the new patent of "Anti-fog and color-changing lens" No. TW-M542774 of the Republic of China, which discloses an anti-fog and color-changing lens. The anti-fog and color-changing lens includes a lens body, an anti-fog sheet and a color-changing sheet, and the lens body has a front surface and a rear surface, and the anti-fog sheet is formed on the rear surface of the lens body, and the color-changing sheet is formed on the front surface of the lens body.

As mentioned above, the antifog sheet of the aforementioned patent No. TW-M542774 is composed of a first PC film and an antifog film bonded to each other with an optical adhesive to form a first adhesive assembly, and the color-changing sheet is composed of a photochromic material sandwiched between a second PC film and a third PC film to form a second multi-layer assembly.

However, the lens body, anti-fog sheet and color-changing sheet of the aforementioned patent No. TW-M542774 are combined with several PC films to form the first adhesive assembly and the second multi-layer assembly. In this way, the manufacturing method needs to perform optical adhesive bonding and injection molding operations respectively. Therefore, it not only has the disadvantage of complicated manufacturing process, but also has the disadvantage of complicated overall structure.

Another commonly used anti-fog optical lens device and its manufacturing method, for example: the new patent of "Anti-fog Lens" No. TW-M544409 of the Republic of China, which discloses an anti-fog lens. The anti-fog lens includes a lens body, a plastic film, a UV adhesive layer and an anti-fog film, and the lens body has a front surface and a rear surface.

As mentioned above, the UV adhesive layer of the aforementioned patent No. TW-M544409 is firstly attached to the plastic film and the anti-fog film, and then the UV adhesive layer is irradiated with ultraviolet light to glue the plastic film and the anti-fog film together to form an anti-fog sheet body, and the lens body is injection molded on the surface of the plastic film of the anti-fog sheet body.

However, the manufacturing method of the lens body, plastic film, UV adhesive layer and anti-fog film of the aforementioned patent No. TW-M544409 requires UV gluing process, UV light curing process and injection molding process respectively. Therefore, it not only has the disadvantage of complicated manufacturing process, but also has the disadvantage of complicated overall structure, and its UV light curing process is easy to affect the quality of the anti-fog lens.

Another commonly used anti-fog optical lens device and its manufacturing method, for example: the new patent of "Anti-fog lens and goggle device" in the Republic of China Patent Publication No. TW-M552108, which discloses an anti-fog lens. The anti-fog lens includes a protective layer and an anti-fog layer, and the protective layer of the anti-fog lens has a front surface and a rear surface.

As mentioned above, the protective layer of the aforementioned patent No. TW-M552108 is selected as a PC layer, and the antifogging layer is selected as a PET layer or a TAC layer, and the antifogging layer is directly selected to be bonded to the rear surface of the protective layer by injection molding or hot pressing, that is, there is no optically functional structural layer between the protective layer and the antifogging layer or on the combined layer.

However, although the antifogging layer of the aforementioned patent No. TW-M552108 is directly bonded to the rear surface of the protective layer by injection molding or hot pressing, the manufacturing method does not further disclose how to simplify the formation of the antifogging layer on the rear surface of the protective layer to reduce the complexity of the overall manufacturing process.

Another commonly used anti-fog optical lens device and its manufacturing method, for example: the new patent of "Anti-fog Thin Frame Snow Goggles" No. TW-M553811 of the Republic of China, which discloses an anti-fog thin frame snow goggles. The anti-fog thin frame snow goggles include a lens body, and the lens body includes a light-transmitting layer, a front anti-fog layer, a filter layer and a rear anti-fog layer, and the lens body has a front surface and a rear surface.

As mentioned above, the front antifog layer and filter layer of the aforementioned patent No. TW-M553811 are located on the front surface of the lens body by dip-coating, and the rear surface is located on the rear surface of the lens body, that is, there is no optically functional structural layer on the rear surface of the lens body.

However, although the front antifogging layer of the aforementioned patent No. TW-M553811 is directly bonded to the front surface of the lens body by dip coating, the manufacturing method does not further disclose how to simplify the formation of any antifogging layer on the rear surface of the lens body to reduce the complexity of the overall manufacturing process.

Another commonly used anti-fog optical lens device and its manufacturing method, for example: the new patent of "Anti-fog Photochromic Lens" No. TW-M583056 of the Republic of China, which discloses an anti-fog photochromic lens. The anti-fog photochromic lens includes a lens, a first transparent plastic sheet, a photochromic material layer, a second transparent plastic sheet and an anti-fog film, and the lens has a front surface and a rear surface.

As mentioned above, the photochromic material layer of the aforementioned patent No. TW-M583056 is sandwiched between the first transparent plastic sheet and the second transparent plastic sheet, and the first transparent plastic sheet, the photochromic material layer and the second transparent plastic sheet are glued to form a photochromic composite layer, and the photochromic composite layer and the antifogging film are further glued to form an antifogging color-changing composite sheet.

However, the first transparent plastic sheet, the photochromic material layer and the second transparent plastic sheet of the aforementioned patent No. TW-M583056 are glued together with the anti-fog color-changing composite sheet to form the lens by injection molding. In the manufacturing method, multiple gluing operations and injection molding operations are required. Therefore, it not only has the disadvantage of complicated manufacturing process, but also has the disadvantage of complicated overall structure.

Obviously, the conventional optical lens devices and their manufacturing methods of the aforementioned U.S. Patent No. US-10259744, Republic of China Patent Publication No. TW-I754919, No. TW-I588516, No. TW-M542774, No. TW-M544409, No. TW-M552108, No. TW-M553811 and No. TW-M583056 are bound to have a need for further improvement in order to provide a composite layered optical lens device.

FIG. 2 is a schematic diagram of the structure of the optical lens device with a functional film of the first preferred embodiment of the present invention; FIG. 2A is a schematic diagram of the combined structure of the optical lens device with a functional film of the first preferred embodiment of the present invention. Referring to FIGS. 2 and 2A, for example, the optical lens device with a functional film of the first preferred embodiment of the present invention comprises an optical substrate layer 10, at least one corona-treated surface 100, at least one optical adhesive layer 20 and at least one functional film 3, and the optical substrate layer 10, the corona-treated surface 100, the optical adhesive layer 20 and the functional film 3 form an optical lens device 1 with a reinforced structure.

Please refer to Figures 2 and 2A again. For example, in another preferred embodiment of the present invention, an optical gain material layer can be selectively disposed between the optical substrate layer 10 and the optical adhesive layer 20, between the optical substrate layer 10 and the functional film 3, or between the optical adhesive layer 20 and the functional film 3.

Please refer to Figures 2 and 2A again. For example, the optical substrate layer 10 has a uniform thickness, and the optical substrate layer 10 is selected from a glass substrate layer, a plastic substrate layer, an environmentally friendly plastic substrate layer, a polycarbonate substrate layer, a polymethyl methacrylate substrate layer, a poly(methyl methacrylate), PMMA substrate layer, a nylon substrate layer, a cyclic olefin polymer substrate layer, a cyclic olefin copolymer substrate layer, a cyclic olefin copolymer substrate layer, a cyclic block copolymer substrate layer, or a substrate layer having similar properties.

Please refer to Figures 2 and 2A again. For example, a first front surface 11 and a second rear surface 12 (e.g., surfaces with various curvatures or spherical surfaces) are arranged on the optical substrate layer 10, and the first front surface 11 of the optical substrate layer 10 is located at an outer side position during use, and the second rear surface 12 of the optical substrate layer 10 is located at an inner side position during use.

Please refer to Figures 2 and 2A again. For example, the optical adhesive layer 20 is formed on the second rear surface 12 (e.g., a portion of the surface (e.g., the center or the periphery) or the entire surface) or the first front surface 11 of the optical substrate layer 10 by appropriate technical means (e.g., spray coating, spin coating, single-layer or multi-layer spray coating), and the optical adhesive layer 20 has a predetermined uniform thickness (e.g., less than about 240 μm or other appropriate thickness), and the optical adhesive layer 20 has a predetermined refractive index, a predetermined transparency or other optical properties.

Please refer to Figures 2 and 2A again. For example, the material of the functional film 3 can be selected from a polycarbonate (PC) material, a triacetyl celluose (TAC) material, a cellulose acetate (CA) material, a cellulose acetate propionate (CAP) material, a polyethylene (PE) material, a polypropylene (PP) material, other materials (such as glass) or any combination thereof.

Please refer to Figures 2 and 2A again. For example, the corona treated surface 100 is selectively formed on the optical adhesive layer 20 of the second rear surface 12 (or the first front surface 11) of the optical substrate layer 10 by appropriate technical means, so that the functional film 3 on the second rear surface 12 of the optical substrate layer 10 can appropriately improve its adhesive properties, strengthen its overall structural strength and reduce its configuration thickness.

FIG. 3 is a schematic diagram of the structure of an optical lens device with a functional film according to another preferred embodiment of the present invention, which corresponds to FIG. 2.

Please refer to FIG. 3 again. For example, in another preferred embodiment of the present invention, an optical gain material layer can be selectively disposed between the optical substrate layer 10 and the optical adhesive layer 20, between the optical substrate layer 10 and the functional film 3, or between the optical adhesive layer 20 and the functional film 3.

Please refer to FIG. 3 again. For example, the anti-scratch protective layer 40 is used to protect the functional film 3 attached thereto, and the anti-scratch protective layer 40 is used to provide an anti-scratch protective property on the functional film 3 to prevent the functional film 3 from being scratched. The anti-scratch protective layer 40 can be selected from an organic reinforcing layer, an organic and inorganic reinforcing layer, an inorganic reinforcing layer or a reinforcing layer with similar properties.

Please refer to FIG. 3 again. For example, another preferred embodiment of the present invention can selectively form at least one corona treated surface on the first front surface 11, the second rear surface 12 or both of the optical substrate layer 10, so that it has better adhesion properties, eliminates impurities, increases surface energy, adjusts polarity or other related properties, so as to appropriately improve its adhesion properties, strengthen its overall structural strength and reduce its configuration thickness.

FIG. 4 is a schematic diagram of the process of manufacturing a method for an optical lens device with a functional film according to a preferred embodiment of the present invention. Referring to FIG. 4, for example, the method for manufacturing an optical lens device with a functional film according to a preferred embodiment of the present invention includes steps S1, S2, S3 and S4, and steps S1, S2, S3 and S4 can be reversed in order, integrated, reduced, deleted or otherwise adjusted according to various requirements.

For example, the manufacturing method of the optical lens device with functional film of the preferred embodiment of the present invention includes step S1: First, the first front surface 11 and the second rear surface 12 are appropriately arranged on the optical substrate layer 10 by appropriate technical means (for example: fully automatic, semi-automatic or manual method), and the first front surface 11 corresponds to the second rear surface 12.

Please refer to Figures 2, 2A, 3 and 4 again. For example, the manufacturing method of the optical lens device with functional film of the preferred embodiment of the present invention includes step S2: Then, the first front surface 11 or the second rear surface 12 of the optical substrate layer 10 is subjected to a corona treatment operation for at least a predetermined time by appropriate technical means (for example: fully automatic, semi-automatic or manual method) to form the corona treated surface 100.

Please refer to Figures 2, 2A, 3 and 4 again. For example, according to various gain adhesion characteristics, the corona treatment operation requires a predetermined electrode power to perform a corona treatment on the first front surface 11 or the second rear surface 12 of the optical substrate layer 10, and the corona treatment operation appropriately performs a corona treatment on the first front surface 11 or the second rear surface 12 of the optical substrate layer 10 for at least a predetermined time, that is, the corona treatment time range.

Please refer to Figures 2, 2A, 3 and 4 again. For example, the corona-treated surface 100 can be selectively formed into a flat surface, a curved surface, a hyperbola surface, a spherical surface or an aspherical surface, and the aspherical surface can be applied to an aspherical optical lens in optics, that is, the aspherical optical lens is not a circular surface from the center to the edge, and has a variable curvature from the center to the edge, so as to provide optical properties different from those of a spherical optical lens.

Please refer to Figures 2, 2A, 3 and 4 again. For example, the corona treated surface 100 can have better adhesion properties, remove impurities, increase surface energy, adjust polarity or other related properties after corona treatment. The corona treated surface 100 is affected by its material type, ambient temperature and substrate thickness.

Please refer to Figures 2, 3 and 4 again. For example, the manufacturing method of the optical lens device with functional film of the preferred embodiment of the present invention includes step S3: Then, a single layer or multiple layers of the optical adhesive layer 20 are arranged on a predetermined area (for example, a part of the surface (for example, the center or the periphery) or the entire surface) of the second rear surface 12 (or the first front surface 11) of the optical substrate layer 10, or on the first front surface 11.

Please refer to Figures 2, 2A, 3 and 4 again. For example, the manufacturing method of the optical lens device with functional film of the preferred embodiment of the present invention includes step S4: Then, the functional film 3 is combined with (corresponding to) the optical adhesive layer 20 attached to the corona-treated surface 100 of the second rear surface 12 (or the first front surface 11) of the optical substrate layer by appropriate technical means (for example: fully automatic, semi-automatic or manual method) to form a reinforced structure-treated substrate layer.

Please refer to Figures 2, 2A, 3 and 4 again. For example, the functional film 3 may have a predetermined uniform thickness (e.g., about 10 mm or other appropriate thickness), and the functional film 3 may be selected from a polyvinyl alcohol (PVA) film or a film with similar properties (e.g., a flexible functional film).

Please refer to Figures 2, 2A, 3 and 4 again. For example, the functional film 3 has a front surface (not marked) and a rear surface (not marked), and in another preferred embodiment of the present invention, the corona treatment operation can be performed on the front surface (e.g., part of the surface or the entire surface) or the rear surface (e.g., part of the surface or the entire surface) of the functional film 3, or both.

Please refer to Figures 2, 2A, 3 and 4. For example, the functional film 3 can have better adhesion properties, remove impurities, increase surface energy, adjust polarity or other related properties after corona treatment. The corona treatment surface of the functional film 3 is affected by the material type characteristics, ambient temperature and film thickness.

FIG. 5 shows a schematic diagram of the structure of the optical lens device with functional film of the second preferred embodiment of the present invention. Referring to FIG. 5, for example, the optical lens device with functional film of the second preferred embodiment of the present invention comprises an optical substrate layer 10, at least one corona treated surface 100, at least one optical adhesive layer 20 and at least one heat set treated film 30, and the optical substrate layer 10, the corona treated surface 100, the optical adhesive layer 20 and the heat set treated film 30 form an optical lens device 1a with a reinforced structure.
