請參閱第1圖，其係為本發明之***式稜鏡製造方法之流程圖。本發明之***式稜鏡製造方法包含下列步驟：(S11)注入一光學透明材料於一模具內，以形成一透明載體，且該透明載具具有一第一容室及一第二容室；(S12)注入一固定膠於第一容室及 第二容室；(S13)提供一反射鏡及一半穿透半反射鏡，且反射鏡具有一凸面；(S14)***反射鏡至第一容室，凸面相對於第二容室，以固定反射鏡於透明載體；以及(S15)***半穿透半反射鏡至第二容室，以固定半穿透半反射鏡於透明載體，以形成具有特定形狀之一光學稜鏡。 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.
請配合第1圖並一併參閱第2、3、4圖。第2、3、4圖分別為光學稜鏡之實施例之第一、第二、第三結構示意圖。本實施例中的光學稜鏡100，其可利用上述的本發明之***式稜鏡製造方法而形成，光學稜鏡100包含透明載體10、反射鏡20及半穿透半反射鏡30。其中，第2圖係為光學透明材料注入模具時由側邊觀之，第3圖係為光學稜鏡100由側邊觀之，而第4圖則由端面觀之。 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.
進一步來說，本發明之***式稜鏡製造方法可先依據實際需求，設計或配置出可製造出特定形狀的光學稜鏡100的模具900。接著如步驟(S11)所示的，將利用射出成型的方式將光學透明材料注入模具900中，待一段時間後模具900中的光學透明材料會定型以形成透明載體10。其中，透明載體10可例如為柱狀或其他適合之形狀，其具有一第一容室11及一第二容室12。第一容室11之形狀設置可對應於反射鏡20，而第二容室之形狀設置可對應於半穿透半反射鏡30。 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.
須特別說明的是，第一容室11的截面形狀可為相對地具有一平面及一凸面的容室，而第二容室12的截面形狀大致上可為長條狀的四邊形，且短邊的端部更凹設有一空間。其中，第一容室 11與第二容室12之間具有一夾角，即第二容室12與第一容室11的上述平面之間夾有一預定角度。此外，第一容室11與第二容室12與透明載體10的側邊距離較佳的可小於2mm，而與透明載體10的底邊距離可小於1mm，此可避免產生破裂的情形。 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.
接著如步驟(S12)所示的，注入固定膠於第一容室11及第二容室12中。值得注意的是，固定膠的折射率應與光學透明材料的折射率一致。 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.
如步驟(S13)所示，提供反射鏡20及半穿透半反射鏡30。反射鏡20可具有倒圓角或倒斜角。舉例來說，反射鏡20之相鄰二個面所交之夾角可例如經由磨圓或去除尖銳之夾角之程序，藉以使得反射鏡20之四周之夾角為倒圓角(例如經由磨圓之程序後)或倒斜角(例如經由去除尖銳之夾角之程序後)。此外，反射鏡20可例如以光學透鏡為基體，再鍍上或塗佈反射材料於此光學透鏡之表面上，藉以形成反射鏡20。並且，此光學透鏡可為凸面透鏡或凹面鏡，藉以使得反射鏡20為具有凸面或凹面的反射膜之反射鏡。 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.
半穿透半反射鏡30可為偏極化板或其他可部分穿透光部分反射光之板，其亦可例如為於一平板上鍍膜或塗佈塗層以使其整體具有光半穿透半反射(或任意比例之光穿透/反射)之特性而所形成。同樣地，半穿透半反射鏡30可具有倒圓角或倒斜角，舉例來說，半穿透半反射鏡30之四周或其中之至少一角可例如透過磨圓或去除尖銳之夾角之程序，而呈現倒圓角或倒斜角之形式。此外，半穿透半反射鏡30可例如以平板玻璃為基體(但不應侷限於此，此 基體可為任意之透明板狀基體)，再鍍上或塗佈半穿透半反射膜或偏極化膜於此基體之表面上，藉以使得一極化光可穿透此半穿透半反射鏡30，且此半穿透半反射鏡30可反射另一極化光。此外，反射鏡20及半穿透半反射鏡30之耐熱度及耐壓度可大於習知之具有斜面之稜鏡之耐熱度及耐壓度。 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.
最後如步驟(S14)、(S15)所示，分別將反射鏡20***第一容室11，而將半穿透半反射鏡30***第二容室12，以利用固定膠而使反射鏡20與半穿透半反射鏡30分別固定於第一容室11與第二容室12中，從而形成具有特定形狀的光學稜鏡100。由於反射鏡20及半穿透半反射鏡30具有倒圓角或倒斜角，因此當反射鏡20及半穿透半反射鏡30***第一容室11及第二容室12時，可易於***，且可使透明載體10適當的包覆反射鏡20及半穿透半反射鏡30。即固定膠形成固定膠層而介於反射鏡20與透明載體10之間及半穿透半反射鏡30與透明載體10之間。 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.
由於第一容室11與第二容室12之間具有一夾角，因此固定於透明載體10的反射鏡20及半穿透半反射鏡30之間亦具有一夾角。此夾角可約略為30至60度之範圍內，藉以達到較佳之光穿透及光反射以及較佳之影像顯示效果。 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.
此外，第一容室11與第二容室12在可適當夾持固定反射鏡20及半穿透半反射鏡30的條件下，其可略大於反射鏡20及半穿透半反射鏡30。因此，當反射鏡20及半穿透半反射鏡30***第一容室11及第二容室12時，溢出的固定膠可流動至多出的空間上。舉 例來說，第二容室12的截面形狀大致上可為長條狀的四邊形，且短邊的端部更凹設有一空間，因此第二容室12可藉由凹設的空間夾持半穿透半反射鏡30，而多餘的固定膠可流至四邊形的多餘的空間，或凹設的空間的多餘空間。 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.
其中，模具900可具有至少一進膠口921、922、923及924，藉以提供通道以注入光學透明材料於模具900中，且進膠口921、922、923及924之位置可相關於第一容室11及第二容室12之位置，藉以避免不飽模現象。舉例來說，進膠口921、922、923及924可分別設置於模具900之二端，藉以使得光學透明材料可於模具900之兩端各別注入於模具900中。進膠口921、922可設置於模具900其中一端的之上方與下方，進膠口923、924可設置於模具900另一端的之上方與下方。更甚者，例如設置於第一容室11所對應之模具900之上方及/或設置於第二容室12所對應之模具900之上方，藉以使得光學透明材料於從進膠口921、922、923及924注入後可流至模具900中之各個位置，藉以避免不飽膜現象。其中，光學透明材料可例如為矽膠、環氧樹脂或其他適合之光學透明塑膠。 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.
除此之外，步驟(S11)更可利用一些步驟，藉以因應注入模具900中之光學透明材料之收縮比例，而進行修正以使得射出後之透明載體10之外觀可更加地整齊漂亮，且更可降低成品與理論之光學路徑之差異。舉例來說，先計算出所欲注入之光學透明材料之材料收縮比率，調整模具900內部之形狀或元件之間的對應關 係，藉以使得模具900可對應於所計算出之材料收縮比率，以得到外觀較為整齊漂亮之光學稜鏡。其中，亦可依據所欲注入模具900中之光學透明材料之材料收縮比率，而修改或設計模具900之製造參數(例如形狀、模具元件之數量或對應關係、製造材料及製造環境等)，藉以使得製造出來之模具900即可對應於所計算出之材料收縮比率。 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.
請進一步配合參閱第5圖至第6圖，第5圖係為本發明之***式稜鏡製造方法之注入光學透明材料時之第一實施態樣示意圖，第6圖係為本發明之***式稜鏡製造方法之注入光學透明材料時之第二實施態樣示意圖。如圖所示，於注入光學透明材料於模具900中時，先使得模具900之第一組件901及第二組件902之間具有距離d(亦即使得模具900不完全閉鎖，如第5圖所示)，再於注入後之一預設時間後，閉鎖模具900之第一組件901及第二組件902(亦即使得距離d為零或近似於零，如第6圖所示)。舉例來說，可先使得模具900之第一組件901及第二組件902之間具有距離d，再利用注入元件將光學透明材料注入於模具900中，由於第一組件901及第二組件902之間具有距離d，因此會有部分之光學透明材料從第一組件901及第二組件902之間流出，而於注入之時間區間中，亦或者於注入後之一預設時間後，可計算(或測量)模具900內之各平面之壓力，待計算(或測量)所得之各個壓力值接近一致後或約略相同後，施加壓力給第二組件902以使得第二組件902朝向第一組件901之方向移動，藉以壓縮閉鎖第一組件901及第二組件902。 之後，再經過一段時間後(即等待光學透明材料凝固後)，拆開模具900以得到具有特定形狀之光學稜鏡。 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.
即，本發明之方法更包含計算模具之一模具閉鎖時間，以形成透明載體的步驟；其中模具閉鎖時間為光學透明材料注入模具後，光學透明材料之各平面之壓力接近一致時，模具壓縮閉鎖的時間。 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.
另外，本發明之製造方法亦可於模具900內的四周之至少一平面置放有透明平板，藉以固定光學稜鏡之形狀。請參閱第6圖，第7圖係為本發明之***式稜鏡製造方法之製造之光學稜鏡之第二實施例之俯視圖。如圖所示，在注入光學透明材料於模具900之前，更可放置至少一透明平板150於模具900內之四周之至少一平面上，藉以定型光學稜鏡100之特定形狀及尺寸大小。其中，透明平板150亦可鍍上或塗佈有模層，藉以可保護透明平板150或可增加光學稜鏡之特性及/或功能。此外，光學透明材料亦可包覆透明平板150，例如於透明平板150之外側包覆厚度小於1毫米之薄膜，並且由於包覆於透明平板150之外側之薄膜均勻且厚度相對較薄，因此可使得光學透明材料於收縮時會受限於透明平板150之位置，而降低由光學透明材料所形成之透明載體10之收縮比例。 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.
綜上所述，本發明之***式稜鏡製造方法所製造出的光學稜鏡可透過光學透明以射出形成透明載體10，以供反射鏡20及半穿透半反射鏡30容置及固定，藉以達到較佳之外觀、較佳之光學稜鏡中之光學路徑以及較佳之影像顯示效果。 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.
