Description of the Invention: [Technical Field] The present invention relates to a method of manufacturing a composite aspherical mirror by injecting uv glue onto a lens surface. [Prior Art] Generally, in the process of manufacturing a spherical lens, the glass material is first heat-molded into a prototype of a desired lens, and then cut by a spherical cutting machine, and then coarsely ground and finely ground by a grinding machine. However, when light passes through the lens sheet, different refractive index is usually generated due to different wavelengths of light. The adjacent light may not be accurately projected onto the focus, which may adversely affect the sharpness of the image to be captured. In view of this, there are later generations who have developed aspherical lenses to solve the above-mentioned disadvantages of the spherical mirrors that cannot be accurately focused. Figure 2 shows that the current composite aspherical lens process mainly includes the following steps: μ 1 · Fix the lens (5 〇) on the fixture. 3 · Press the mold onto the UV glue (6 〇).
使UV膠（6 〇 ) 複合非球面鏡片 (5 0 0);以及 5 ·脫模。 2 ·於鏡片（5 〇 )上灌注肝膠（6 〇 )。 上述製程雖可生產出非球面鏡片 鏡片仍存在者下述缺點： ，然而其所製造的 1 ·物理性質不良·· •經貫驗得之，直接將UV膠（6 1252930 ο)灌注於鏡片雛形上再加以硬化成形，其引張剪斷接 著強度（Lap Shear Strength)約為 6 6 kgf/cm2，容易 因脫模時的拉力作用產生變形，而無法使用精度之要 求。 2 ·非球面鏡片之習用製程於脫模時，模具係直接 軸向脫離已硬化的UV膠，因此，在脫模的瞬間模具會 對已硬化的UV膠產生一真空拉力，此拉力對於UV膠（6 0 )與鏡片（5 0 )之結合將會產生負面的影響，甚至 使得UV膠（6 0 )與鏡片（5 0 )間產生缝隙，嚴重 影響入射光線的折射。 緣是，本發明人乃針對上述非球面鏡片製程之各項 缺失5本者鎖而不捨的精神與精盈求精的目的5積極不 斷地加以研究改進，並經長期之努力與試驗，終於開發 設計出本發明。 【發明内容】 本發明之主要目的，在於解決上述的問題而提供 一種不良率低且UV膠結合強度佳之複合非球面鏡片製 造方法。 為達前述之目的，本發明主要係包括下列步驟： 1 ·將鏡片之頂面蒸鍍一層三氧化二銘（A12〇3)。 2·將已蒸鍍三氧化二鋁之鏡片固定於夾具上。 3 ·將UV膠灌注於鏡片之三氧化二鋁層上。 4 ·將一具複合非球面模穴之模具壓合於UV膠上。 5 ·對UV膠照射紫外線，使UV膠硬化成形並 1252930 與鏡片結合成為一複合非球面鏡片。 6·旋轉模具並同時脫模。 本奄明之上述及其他目的與停， a 、、 選用實施狀詳細朗與關巾，獲得深人了ζ下。迷所 當然，本發明在某些步驟，或步驟之安排上 :所：同’但所選用之實施例，則於本說明書中，予: 洋細說明，並於附圖中展示其構造。 【實施方式】 明’閱第1圖中所不者為本發明所較具體實施 例’此僅供制之用，在專物t上並不受限制 主要係包括下列步驟： 本發明係為一種複合非球面鏡片之製造方法，盆 旅 07 紅—ΙΓ 土咖· ” 將鏡片（10)雛形之其中-侧鏡面蒸鑛一： 氧化二鋁（Α12〇3)層（1 )。 一 丄·將已蒸鍍三氧化二鋁之鏡片（i 〇 )固定於央 具（4 )上。 3 ·將 UV 膠（2 〇 )遒、、:^ β η ν乙υ」/隹庄於二虱化二鋁層（1 1、 上0 y 4 ·將-具複合非球面模穴（3工）之模具（3 〇) 壓合於UV膠（2 〇 )上。 、5、對UV膠如、射紫外線光（4 〇 )，促使肝膠硬 化成形並與鏡片結合成為—複合非球面鏡片（丨〇 〇)。 6 ·旋轉模具並同時脫模。 於本發明步驟2中，於灌注^膠前鑛上鏡片的三 氧"化一'叙層（Ί 1、 uv rn r 0 、1 1 )，除可增加光穿透性外，更 uv^ Q)與鏡片UQ)間之附著力’可將石; 至^之^張剪斷接著強度由原先的66如心2 =Make UV glue (6 〇) composite aspherical lens (500); and 5 · demoulding. 2 · Infuse the liver glue (6 〇) on the lens (5 〇). Although the above process can produce aspherical lens, there are still the following disadvantages: However, the manufactured material has poor physical properties. • Through thorough inspection, the UV glue (6 1252930 ο) is directly poured into the lens prototype. The hardening is further formed, and the tensile shear strength is about 6 6 kgf/cm 2 , which is easily deformed by the tensile force during demolding, and the precision cannot be used. 2 · The aspherical lens is used in the process of demoulding, the mold is directly axially separated from the hardened UV glue. Therefore, at the moment of demolding, the mold will generate a vacuum tension on the hardened UV glue. The combination of (60) and lens (50) will have a negative effect, even causing a gap between the UV glue (60) and the lens (50), seriously affecting the refraction of incident light. The reason is that the present inventors have actively researched and improved the spirit of the above-mentioned aspherical lens manufacturing process, and the purpose of excellence and refinement, and after long-term efforts and experiments, finally The present invention was developed and designed. SUMMARY OF THE INVENTION The main object of the present invention is to solve the above problems and to provide a composite aspherical lens manufacturing method having a low defect rate and excellent UV bonding strength. For the purpose of the foregoing, the present invention mainly comprises the following steps: 1) The top surface of the lens is vapor-deposited with a layer of bismuth oxide (A12〇3). 2. Fix the vapor-deposited aluminum oxide lens on the fixture. 3 · Inject the UV glue onto the aluminum oxide layer of the lens. 4 · Press a mold of a composite aspheric cavity onto the UV glue. 5 · The UV glue is irradiated with ultraviolet rays to make the UV glue hardened and the 1252930 is combined with the lens to form a composite aspherical lens. 6. Rotate the mold and demold at the same time. The above and other purposes of this book and the stop, a,, the selection of the implementation of the detailed Lang and Guan towel, won the deep people. Of course, the present invention is in some steps, or steps of the arrangement: the same as the embodiment selected, but in the present specification, it is described in detail, and its construction is shown in the drawings.

The generated pulling force is minimized, and the mirror (four) degree of the uv rubber hard M = is prevented from being pulled and deformed. As described above, the composite aspherical lens manufactured by the invention can solve the problem that the spherical lens can not be accurately focused, and the bonding strength between the UV glue and the lens is greatly improved, and the rotating mold is used to destroy. The vacuum state between the hardened uv and the hardened uv glue reduces the tensile force generated by the mold on the lens during demolding, and avoids deformation of the cured UV glue; the stripping method is also suitable for molding glass lens forming and plastic lens forming.
