The subject matter is only for the purpose of illustration and description. It is not intended to be a true proportion and precise configuration after the implementation of the present invention. Therefore, the scope and configuration relationship of the attached drawings should not be interpreted or limited. First described.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the embodiments of the present invention will be described with reference to the accompanying drawings.

Please refer to FIG. 1 , which is a flow chart of a method for manufacturing a plug-in type according to the present invention. The method for manufacturing a plug-in crucible of the present invention comprises the steps of: (S11) injecting an optically transparent material into a mold to form a transparent carrier, and the transparent carrier has a first chamber and a second chamber; (S12) injecting a fixing glue into the first chamber and a second chamber; (S13) providing a mirror and a half penetrating half mirror, wherein the mirror has a convex surface; (S14) inserting the mirror into the first chamber, the convex surface being fixed relative to the second chamber The mirror is mounted on the transparent carrier; and (S15) the transflective half mirror is inserted into the second chamber to fix the transflective half mirror on the transparent carrier to form an optical pupil having a specific shape.

Please refer to Figure 1 and refer to Figures 2, 3 and 4. Figures 2, 3, and 4 are schematic views of the first, second, and third structures of the optical cymbal embodiment, respectively. The optical crucible 100 of the present embodiment can be formed by the above-described plug-in crucible manufacturing method of the present invention, and the optical crucible 100 includes a transparent carrier 10, a mirror 20, and a transflective mirror 30. 2 is a side view of the optically transparent material when it is injected into the mold, and FIG. 3 is an optical 稜鏡100 viewed from the side, and FIG. 4 is viewed from the end.

Further, the insert type crucible manufacturing method of the present invention can first design or configure a mold 900 capable of manufacturing a specific shape of the optical crucible 100 according to actual needs. Next, as shown in step (S11), the optically transparent material will be injected into the mold 900 by means of injection molding, and the optically transparent material in the mold 900 will be shaped to form the transparent carrier 10 after a period of time. The transparent carrier 10 can be, for example, a column or other suitable shape, and has a first chamber 11 and a second chamber 12. The shape of the first chamber 11 may correspond to the mirror 20, and the shape of the second chamber may correspond to the half mirror 30.

It should be particularly noted that the cross-sectional shape of the first chamber 11 may be a chamber having a flat surface and a convex surface, and the cross-sectional shape of the second chamber 12 may be a substantially quadrangular shape and a short side. The end is more concave with a space. Among them, the first chamber There is an angle between the 11 and the second chamber 12, that is, a predetermined angle is formed between the second chamber 12 and the plane of the first chamber 11. In addition, the distance between the first chamber 11 and the second chamber 12 and the side of the transparent carrier 10 may preferably be less than 2 mm, and the distance from the bottom edge of the transparent carrier 10 may be less than 1 mm, which avoids the occurrence of cracking.

Next, as shown in the step (S12), the fixing glue is injected into the first chamber 11 and the second chamber 12. It is worth noting that the refractive index of the fixing glue should be consistent with the refractive index of the optically transparent material.

As shown in step (S13), the mirror 20 and the transflective mirror 30 are provided. The mirror 20 can have rounded or chamfered corners. For example, the angle between the adjacent two faces of the mirror 20 can be, for example, via a process of rounding or sharpening the angle, so that the angle around the mirror 20 is rounded (eg, via a rounding procedure). After) or chamfer (for example, after removing the sharp angle). In addition, the mirror 20 can be formed, for example, with an optical lens as a substrate, and then coated or coated with a reflective material on the surface of the optical lens to form the mirror 20. Also, the optical lens may be a convex lens or a concave mirror, whereby the mirror 20 is a mirror having a convex or concave reflecting film.

The transflective mirror 30 can be a polarized plate or other plate that can partially partially penetrate the light, which can also be coated or coated on a flat plate to make the whole light semi-transparent. It is formed by the characteristics of semi-reflection (or light penetration/reflection of any ratio). Similarly, the transflective mirror 30 can have rounded or chamfered corners, for example, a procedure in which at least one of the perimeters of the transflective mirror 30 or at least one of the corners can be rounded or sharpened, for example. , in the form of round or chamfered corners. In addition, the transflective mirror 30 may be based on, for example, a flat glass (but should not be limited thereto). The substrate may be any transparent plate-like substrate), and then a semi-transparent semi-reflective film or a polarizing film is coated or coated on the surface of the substrate, so that a polarized light can penetrate the transflective The mirror 30, and the transflective mirror 30, reflects another polarized light. In addition, the heat resistance and pressure resistance of the mirror 20 and the transflective mirror 30 can be greater than the heat resistance and pressure resistance of the conventional beveled surface.

Finally, as shown in steps (S14) and (S15), the mirror 20 is inserted into the first chamber 11 and the transflective mirror 30 is inserted into the second chamber 12 to make the mirror 20 with the fixing glue. The transflective mirror 30 is fixed in the first chamber 11 and the second chamber 12, respectively, to form an optical crucible 100 having a specific shape. Since the mirror 20 and the transflective mirror 30 have rounded or chamfered angles, when the mirror 20 and the transflective mirror 30 are inserted into the first chamber 11 and the second chamber 12, it is easy to Insertion, and the transparent carrier 10 can be suitably coated with the mirror 20 and the transflective mirror 30. That is, the fixing glue forms a fixing glue layer between the mirror 20 and the transparent carrier 10 and between the transflective mirror 30 and the transparent carrier 10.

Since there is an angle between the first chamber 11 and the second chamber 12, the mirror 20 fixed to the transparent carrier 10 and the semi-transmissive mirror 30 also have an angle. The angle can be approximately 30 to 60 degrees, thereby achieving better light penetration and light reflection and better image display.

In addition, the first chamber 11 and the second chamber 12 may be slightly larger than the mirror 20 and the transflective mirror 30 under the condition that the fixed mirror 20 and the transflective mirror 30 can be appropriately clamped. Therefore, when the mirror 20 and the transflective mirror 30 are inserted into the first chamber 11 and the second chamber 12, the overflowing fixing glue can flow to the extra space. Lift For example, the cross-sectional shape of the second chamber 12 may be substantially a quadrangular quadrangle, and the end of the short side is further recessed with a space, so that the second chamber 12 can be sandwiched by the recessed space. The half mirror 30 is penetrated, and the excess fixing glue can flow to the excess space of the quadrilateral or the excess space of the recessed space.

Wherein, the mold 900 can have at least one glue inlet 921, 922, 923 and 924, thereby providing a channel for injecting an optically transparent material into the mold 900, and the positions of the glue inlets 921, 922, 923 and 924 can be related to the first The positions of the chamber 11 and the second chamber 12 are used to avoid the phenomenon of insufficient mold. For example, the glue inlets 921, 922, 923, and 924 may be respectively disposed at two ends of the mold 900, so that the optically transparent material may be separately injected into the mold 900 at both ends of the mold 900. The glue inlets 921, 922 may be disposed above and below one end of the mold 900, and the glue inlets 923, 924 may be disposed above and below the other end of the mold 900. Moreover, for example, it is disposed above the mold 900 corresponding to the first chamber 11 and/or disposed above the mold 900 corresponding to the second chamber 12, so that the optically transparent material is applied to the feed port 921, 922. After injection, 923 and 924 can flow to various positions in the mold 900 to avoid the phenomenon of no film. The optically transparent material may be, for example, silicone, epoxy or other suitable optically transparent plastic.

In addition, the step (S11) can further utilize some steps to correct the shrinkage ratio of the optically transparent material injected into the mold 900 so that the appearance of the transparent carrier 10 after the injection can be more neat and beautiful, and more It can reduce the difference between the finished product and the theoretical optical path. For example, first calculating the material shrinkage ratio of the optically transparent material to be injected, and adjusting the shape or the corresponding relationship between the components inside the mold 900. Therefore, the mold 900 can be made to correspond to the calculated material shrinkage ratio to obtain a more tidy and beautiful optical flaw. Wherein, the manufacturing parameters of the mold 900 (for example, the shape, the number or correspondence of the mold components, the manufacturing material and the manufacturing environment, etc.) may be modified or designed according to the material shrinkage ratio of the optically transparent material to be injected into the mold 900. The manufactured mold 900 is made to correspond to the calculated material shrinkage ratio.

Please refer to FIG. 5 to FIG. 6 for further cooperation. FIG. 5 is a schematic view showing a first embodiment of the method for manufacturing an insert type crucible according to the present invention, and FIG. 6 is a plug-in type of the present invention. A schematic view of a second embodiment of the method of manufacturing an optically transparent material. As shown, when injecting the optically transparent material into the mold 900, the first component 901 and the second component 902 of the mold 900 are first provided with a distance d (ie, the mold 900 is not completely locked, as shown in FIG. And then, after a predetermined time after the injection, the first component 901 and the second component 902 of the mold 900 are locked (that is, the distance d is zero or approximately zero, as shown in FIG. 6). For example, the distance between the first component 901 and the second component 902 of the mold 900 may be first, and the optically transparent material is injected into the mold 900 by using the injection component, since the first component 901 and the second component 902 are There is a distance d between them, so that part of the optically transparent material flows out between the first component 901 and the second component 902, and can be calculated in the time interval of the injection or after a preset time after the injection ( Or measuring) the pressure of each plane in the mold 900. After the respective pressure values obtained by the calculation (or measurement) are nearly uniform or approximately the same, pressure is applied to the second component 902 such that the second component 902 faces the first component 901. The direction moves to thereby compress and block the first component 901 and the second component 902. Thereafter, after a period of time (i.e., after waiting for the optically clear material to solidify), the mold 900 is disassembled to obtain an optical crucible having a specific shape.

That is, the method of the present invention further comprises the step of calculating the mold closing time of one of the molds to form a transparent carrier; wherein the mold locking time is after the optically transparent material is injected into the mold, and the pressure of each plane of the optically transparent material is close to the same, the mold is compressed and blocked. time.

Further, in the manufacturing method of the present invention, a transparent flat plate may be placed on at least one of the circumferences of the mold 900 to fix the shape of the optical crucible. Please refer to FIG. 6. FIG. 7 is a plan view showing a second embodiment of the optical crucible manufactured by the method for manufacturing the insert type crucible of the present invention. As shown, prior to injecting the optically transparent material into the mold 900, at least one transparent plate 150 can be placed on at least one of the four sides of the mold 900 to shape the particular shape and size of the optical crucible 100. The transparent plate 150 can also be plated or coated with a mold layer, thereby protecting the transparent plate 150 or increasing the characteristics and/or function of the optical raft. In addition, the optically transparent material may also be coated with the transparent flat plate 150, for example, a film having a thickness of less than 1 mm on the outer side of the transparent flat plate 150, and since the film coated on the outer side of the transparent flat plate 150 is uniform and relatively thin, The optically transparent material is constrained to the position of the transparent plate 150 when it is shrunk, and the shrinkage ratio of the transparent carrier 10 formed of the optically transparent material is lowered.

In summary, the optical cymbal manufactured by the method for manufacturing the entangled cymbal of the present invention can be transparently transparent to form the transparent carrier 10 for accommodating and fixing the mirror 20 and the transflective mirror 30. In order to achieve a better appearance, a better optical path in the optical 以及 and a better image display effect.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
