Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art to which the present invention pertains can easily implement them. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein.

In describing an embodiment of the present invention, if it is determined that a detailed description of a well-known configuration or function may obscure the gist of the present invention, a detailed description thereof will be omitted. And, in the drawings, parts not related to the description of the present invention are omitted, and similar reference numerals are attached to similar parts.

In the present invention, the components that are distinguished from each other are for clearly explaining their respective characteristics, and do not necessarily mean that the components are separated. That is, a plurality of components may be integrated to form one hardware or software unit, or one component may be distributed to form a plurality of hardware or software units. Accordingly, even if not specifically mentioned, such integrated or dispersed embodiments are also included in the scope of the present invention.

In the present invention, components described in various embodiments do not necessarily mean essential components, and some may be optional components. Accordingly, an embodiment composed of a subset of components described in one embodiment is also included in the scope of the present invention. In addition, embodiments including other components in addition to the components described in various embodiments are also included in the scope of the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

2 and 3 show a process method for producing a mirror interpolation lens according to the present invention. First, referring to FIG. 2 , an upper lens and a lower lens injection molds constituting the mirror interpolation lens are manufactured, and then the upper and lower lenses are respectively injection molded using the injection molds ( 201 ). In particular, V grooves 221 may be formed in the upper and lower lenses to facilitate mirror coating and coupling. For example, FIG. 3A shows the upper lens 210 and the lower lens 220 generated through step 201, respectively. However, according to an embodiment of the present invention to be described later, the upper lens may not be formed in advance, but may be formed when combined with a lower mirror lens to be described later. This will be described in detail later with reference to FIGS. 17 to 19 .

Thereafter, a mirror 231 is coated on the V-groove 221 of the lower lens 220 to generate a mirror-coated lower mirror lens ( 202 ). At this time, it is possible to create a plurality of mirrors 231 to be coated with a predetermined size. However, this is only an example and the number of mirrors coated on the lens is not limited. In addition, the present invention has been exemplified by coating the mirror on the lower lens for convenience of explanation, but mirror coating on the upper lens is also possible, and the present invention is not limited to the position where the mirror is coated. For example, FIG. 3( b ) shows the mirror-coated lower mirror lens 230 generated through step 202 .

Next, the lower mirror lens is combined with the upper lens ( 203 ). For example, FIG. 3C illustrates a process of generating a mirror interpolation lens by combining an upper lens and a lower mirror lens for step 203 . In relation to this, the coupling method of the lower mirror lens and the upper lens will be described in detail later with reference to FIGS. 17 to 19 .

The generated mirror interpolation lens may further include a post-processing step of manufacturing an outer shape according to the intended use ( 204 ). However, the present invention does not include any limitation on the post-processing step. Accordingly, it is obvious that a mirror interpolation lens produced through any post-processing may be included within the scope of the present invention.

In this regard, as in step 202 and FIG. 3(b), in generating the mirror-coated lower mirror lens, the V-groove 221 on the lower lens and the size of the coated mirror 231 are very small, so it is stable As such, there is a problem in that it is difficult to perform mirror coating. In particular, the V-groove 221 needs to be manufactured to have a thread-shaped inclined surface, which requires a more precise coating of the small-diameter mirror 231 . These requirements also lead to the mass production of many defective lenses. Accordingly, the present invention proposes an efficient method for producing a mirror-coated lower mirror lens 230 suitable for mass production. Hereinafter, a method of generating the mirror-coated lower mirror lens 230 according to the present invention will be described in detail with reference to FIGS. 4 to 15 .

4 and 5 show a method of producing a mirror-coated lower mirror lens according to a first embodiment of the present invention. First, a lower lens injection mold is manufactured, and the lower lens 310 is injection molded using the manufactured injection mold ( 301 ). Thereafter, the coating mask 320 in which the mirror coating hole 321 is formed is seated on the lower lens 310 ( 302 ). Next, a mirror-coated lower-mirror lens is produced by coating the mirror by applying a mirror-coating material to the mirror-coating hole 321 ( 303 ). Therefore, by using the coating mask 320, a small diameter mirror coating is possible.

Here, the coating mask 320 is manufactured to have an inclined surface in close contact with the V groove of the lower lens. For example, the coating mask 320 may be made of a metal sheet processed by etching, and it is possible to apply various types of coating masks. This will be described later in detail with reference to FIGS. 9 to 13 .

6 to 8 are diagrams illustrating a method for producing a mirror-coated lower mirror lens according to a second embodiment of the present invention. First, a lower lens injection mold is manufactured, and the lower lens 410 is injection molded using the manufactured injection mold ( 401 ). Thereafter, the coating mask 420 in which the hole 421 for mirror coating is formed is seated on the lower lens 410 ( 402 ). Here, the coating mask 420 is manufactured to have an inclined surface in close contact with the V groove of the lower lens. For example, the coating mask 420 may be made of a metal sheet processed by etching, and it is possible to apply various types of coating masks. This will be described later in detail with reference to FIGS. 9 to 13 .

Next, the mask cover 430 in which the perforations 431 having a hole of a specific size are formed is seated on the coating mask 420 for mirror coating ( 403 ). Here, the coating mask 420 for mirror coating must be exposed through the perforation 431 . The remaining mask cover area other than the perforations 431 is manufactured to have a structure capable of close contact with the lower lens on which the coating mask is seated. For example, in order to adhere to the V-groove portion of the lower lens, a V-groove 432 having the same structure must be formed in the mask cover 430 .

In relation to this, FIG. 8 shows a structure in which the lower lens 410, the coating mask 420, and the mask cover 430 are combined. Accordingly, a mirror coating material is applied to the mirror coating hole 421 exposed through the perforation 431 of the mask cover 430 to coat the mirror, and a mirror-coated lower mirror lens is produced ( 404 ).

Accordingly, by further using the mask cover 430 on the coating mask 420 , the adhesion to the lower lens 410 is further increased, and it is possible to more precisely perform mirror coating of a small diameter. In addition, it is possible to prevent the mirror coating material from being poorly applied to areas other than the perforations 431 . For this purpose, various types of perforations 431 may be possible. For example, although the perforation 431 shown in FIG. 7 is disclosed only as a single rectangular structure, as another example, a plurality of perforations to cover all the remaining areas except for the mirror coating hole 421 is also possible. Here, the mask cover 430 may be made of glass or plastic injection or processed products.

Hereinafter, with reference to FIGS. 9 to 13 , the coating masks 320 and 420 will be described in detail. 9 to 11 show a first type of coating mask, according to the present invention. For example, the first coating mask type 520 of the present invention is a case in which the entire coating mask is created with a plurality of sheets. Referring to FIG. 9A , the coating mask 520 made of one sheet may include a first inclined surface 522 and a second inclined surface 523 in the form of a screw thread. Here, the first inclined surface 522 may be configured to have a larger area than the second inclined surface 523 . In particular, it is possible to create the above-described plurality of mirror coating holes 521 on the first inclined surface 522 forming the larger area. However, this is only one example, and may be configured in a different form depending on the purpose of using the mirror interpolation lens. For example, the mirror coating hole 521 may be formed on the second inclined surface 523 forming the smaller area. In addition, the first inclined surface 522 and the second inclined surface 523 may be configured to have the same area.

Referring to FIGS. 9 ( b ) and 9 ( c ), the mirror coating hole 521 may be manufactured to have a structure in which upper and lower hole diameters are different. That is, the upper end diameter t1 may be larger than the lower end diameter t2, and may have a tapered shape. The tapered hole 521 for mirror coating allows the coating solution to be stably applied without flowing down when the mirror coating material is applied.

10 (a), (b), and (c) show, for example, a method of manufacturing the first coating mask type 520 . That is, a half-etched groove 524 is formed in a region where the first inclined surface 522 and the second inclined surface 523 are separated. Thereafter, the second inclined surface 523 is bent around the groove 524 by an angle to be in close contact with the lower lens V-groove, thereby manufacturing a final first coating mask type 520 . For example, in FIG. 10 ( c ), for convenience of explanation, a case bent at a 90 degree angle 525 is illustrated, but this is not a limitation of the present invention, and various angles (eg, It is possible to fabricate the first coating mask type 520 at 120 degrees, 145 degrees, etc.).

11 is a diagram illustrating a method of generating a mirror-coated lower mirror lens using the first coating mask type 520 .

V grooves 511 are formed on the lower lens 510, and a plurality of first coating mask types 520 are formed to suit the number and structure of the V grooves. Here, the first coating mask types 520-1 and 520-2 corresponding to the starting and ending positions of the V-groove 511 may be manufactured to have a different structure from the other first coating mask types 520. For example, in the first coating mask type 520-1 corresponding to the position where the V-groove 511 starts, the first inclined surface 522 and the second inclined surface 523 are formed at an angle of 90 degrees or more. In addition, the first coating mask type 520-2 corresponding to the position where the V-groove 511 ends is the first inclined surface 522 and the second inclined surface 523. ) can be manufactured to be formed at an angle greater than 90. That is, the plurality of first coating mask types 520-1, 520, and 520-2 have a different structure in close contact with the lower lens V-groove 511. The hole 521 for mirror coating may be formed so that mirror coating is possible only at a specific position of the lower lens.

In addition, it is possible to further increase adhesion by seating the above-described coating mask cover 530 on the first type coating masks 520-1, 520, and 520-2. However, according to the first embodiment ( FIGS. 4 and 5 ) of the present invention described above, it is also possible to create a lower mirror lens without the coating mask cover 530 .

12 and 13 show a second coating mask type 620 according to the present invention. For example, the second coating mask type 620 of the present invention is a case in which the entire coating mask is produced with a single sheet. 12 and 13, the coating mask 620 composed of a single sheet may include a first inclined surface 622 and a second inclined surface 623 in the form of a screw thread. Here, the structure of the first inclined surface and the second inclined surface should be manufactured to be able to adhere to the structure of the corresponding lower lens V-groove 611 . A hole 621 for mirror coating may be formed in either the first inclined surface or the second inclined surface. 12 illustrates a case in which the mirror coating hole 621 is formed on the first inclined surface 622 for convenience of explanation, but the present invention is not limited thereto. In this regard, the second coating mask type 620 of the present invention can be configured in a straight or spiral shape. This has the advantage of adaptively responding to various lower lens V-groove 611 structures.

In addition, it is possible to further increase adhesion by seating the above-described coating mask cover 630 on the second type coating mask 620 . However, according to the first embodiment ( FIGS. 4 and 5 ) of the present invention described above, it is also possible to create a lower mirror lens without the coating mask cover 630 .

14 to 16 are diagrams illustrating a method for producing a mirror-coated lower mirror lens according to a third embodiment of the present invention. First, a lower lens injection mold is manufactured, and the lower lens 710 is injection molded using the manufactured injection mold ( 701 ). Thereafter, the coating mask 720 in which the hole 721 for mirror coating is formed is seated on the lower lens 710 (702). Here, the coating mask 720 is manufactured to have an inclined surface in close contact with the V-groove 711 of the lower lens. In FIG. 15, for convenience of explanation, the above-described second type coating mask structure is illustrated as an example, but the present invention is not limited thereto. That is, for example, by applying the first type coating mask described above, it is also possible to apply a plurality of coating masks. The coating mask 720 may be made of an etching-processed metal sheet.

Thereafter, a rubber pad 740 is mounted on the mirror coating mask 720 in an area where the mirror coating hole 721 is not formed ( 703 ).

Next, the mask cover 730 in which the perforation 731 having a hole of a specific size is formed is seated on the coating mask 720 for mirror coating and the rubber pad 740 ( 704 ). Here, through the perforation 731, the coating mask 720 for mirror coating must be made to be exposed. The remaining mask cover area other than the perforations 731 is manufactured to have a structure capable of close contact with the lower lens on which the coating mask is seated. For example, in order to be in close contact with the lower lens V-groove 711 , a V-groove 732 having the same structure must be created in the mask cover 730 .

Here, the rubber pad 740 is manufactured to be sandwiched between the mirror coating coating mask 720 and the mask cover 730, and the lower lens 710, the coating mask 720, and the mask cover ( 730) is used to further increase the adhesion between them. That is, the rubber pad 740 may be seated on the edge regions 726 and 727 in which the mirror coating hole 721 is not formed on the coating mask 720 .

16 illustrates a structure in which the lower lens 710, the coating mask 720, the mask cover 730, and the rubber pad 740 are combined. Thereafter, a mirror coating material is applied to the mirror coating hole 721 exposed through the perforation 731 of the mask cover 730 to coat the mirror, thereby creating a mirror-coated lower mirror lens (704). ).

In relation to this, FIG. 16 (c) shows an example of applying the above-described first type coating mask ( FIGS. 9 to 11 ) as the coating mask 720 , and the gap between the coating mask sheets can be more closely adhered shows

17 to 19 show a coupling method between the generated lower mirror lens and the upper lens according to the present invention. That is, referring again to FIGS. 2 and 3 ( c ), a process of combining the lower mirror lens formed through FIGS. 4 to 16 with the upper lens is required ( 203 ). Through this step 203, a complete mirror interpolation lens can be created. Here, when the upper lens and the lower mirror lens are combined, a method of simply applying an adhesive has a problem of causing defects and gaps due to adhesive. Accordingly, the present invention proposes a method of molding together with the lower mirror lens when combined with the lower mirror lens, without injection molding the upper lens in advance. Hereinafter, various embodiments for implementing step 203 according to the present invention will be described.

17 shows an embodiment process for producing the mirror interpolation lens according to the present invention. Referring to FIG. 17 ( a ) , a lower lens injection mold constituting the mirror interpolation lens is manufactured, and the lower lens is injection molded using the manufactured injection mold. In particular, a V groove may be formed in the lower lens to facilitate mirror coating.

Thereafter, as shown in FIG. 17 ( b ), a mirror-coated lower mirror lens is produced on the V groove of the lower lens using any one of the various embodiments in FIGS. 4 to 16 .

Next, the lower mirror lens is inserted into the mirror lens injection mold. In relation to this, the mirror lens injection mold means an injection mold manufactured according to the shape of the final mirror interpolation lens. For example, FIG. 17( c ) shows a mirror lens injection mold and a lower mirror lens inserted therein.

Thereafter, the upper lens and the lower mirror lens are simultaneously injection molded through the mirror lens injection mold, and the integrated mirror interpolation lens is taken out. For example, FIGS. 17(d), (e), and (f) show the above process, respectively.

Here, according to the embodiment of FIG. 17 of the present invention, by injection molding the upper lens at the same time as the lower mirror lens without pre-fabricating the upper lens with a mold, the problem of impurities due to the use of adhesive can be solved, and the upper and lower lenses can be combined. Accordingly, it becomes possible to solve the misalignment problem. Therefore, mass production of mirror interpolation lenses with improved yield is possible. In particular, the Fig. 17 embodiment of the present invention is suitable for a thermoplastic resin as a lens material.

18 shows another embodiment process for producing the mirror interpolation lens according to the present invention. Referring to FIG. 18 (a), a UV curing mold for the lower lens constituting the mirror interpolation lens is manufactured, and the UV curing mold is used to UV curing the lower lens. In particular, a V groove may be formed in the lower lens to facilitate mirror coating.

Thereafter, as shown in FIG. 18 ( b ), a mirror-coated lower mirror lens is produced on the V-groove of the lower lens using any one of the various embodiments in FIGS. 4 to 16 .

Next, the lower mirror lens is inserted into the mirror lens UV curing mold, and a UV curing agent is applied on the lower mirror lens. In this regard, the UV curing mold frame for the mirror lens means a UV curing mold mold manufactured according to the shape of the final mirror interpolation lens. For example, FIG. 18 ( c ) shows a lower mirror lens inserted into a mirror lens UV curing mold and a UV curing agent applied on the lower mirror lens.

Thereafter, a transparent upper mold identical to the shape of the image lens is placed on the mirror lens UV curing mold frame and UV curing is performed. By making the upper transparent frame the same as the upper lens shape, simultaneous UV curing molding of the upper lens and the lower mirror lens is possible, and the integrated mirror interpolation lens is taken out. For example, FIGS. 18 (d), (e), and (f) illustrate the above process, respectively.

Here, according to the embodiment of FIG. 18 of the present invention, by UV curing molding at the same time as the lower mirror lens without manufacturing the upper lens in advance with a mold, it is possible to solve the problem of impurities due to the use of the adhesive, and also to combine the upper and lower lenses. Accordingly, it becomes possible to solve the misalignment problem. Therefore, mass production of mirror interpolation lenses with improved yield is possible. In particular, FIG. 18 embodiment of the present invention is suitable for a UV Curable Thermosetting Resin as a lens material.

19 shows another exemplary process for producing the mirror interpolation lens according to the present invention. Referring to FIG. 19 ( a ) , a thermosetting mold for the lower lens constituting the mirror interpolation lens is manufactured, and the lower lens is thermosetted using the thermosetting mold. In particular, a V groove may be formed in the lower lens to facilitate mirror coating.

Thereafter, as shown in FIG. 19( b ), a mirror-coated lower mirror lens is produced on the V-groove of the lower lens using any one of the various embodiments in FIGS. 4 to 16 .

Next, the lower mirror lens is inserted into a mold for thermosetting the mirror lens, and a thermosetting agent is applied on the lower mirror lens. In this regard, the mirror lens thermosetting mold frame refers to a thermosetting mold mold manufactured according to the shape of the final mirror interpolation lens. For example, FIG. 19( c ) shows a lower mirror lens inserted into a mirror lens thermosetting mold and a thermosetting agent applied on the lower mirror lens.

Thereafter, an upper mold having the same shape as the image lens is placed on the mirror lens UV curing mold, and thermal curing is performed. By making the upper mold frame the same as the image lens shape, simultaneous thermosetting of the image lens and the lower mirror lens is possible, and the integrated mirror interpolation lens is taken out. For example, FIGS. 19 (d), (e), and (f) show the above process, respectively.

Here, according to the embodiment of Fig. 19 of the present invention, since the upper lens is not made in advance with a mold and thermosetting is performed at the same time as the lower mirror lens, the problem of impurities due to the use of adhesive can be solved and the upper and lower lenses can be combined. Accordingly, it becomes possible to solve the misalignment problem. Therefore, mass production of mirror interpolation lenses with improved yield is possible. In particular, the embodiment of Fig. 19 of the present invention is suitable for a thermosetting resin (Thermal Curable Thermosetting Resin) as a lens material.

The present invention described above, for those of ordinary skill in the art to which the present invention pertains, various substitutions, modifications and changes are possible without departing from the technical spirit of the present invention. It is not limited by the drawing.
