據此，圖5為對應圖4的製作流程與適用材質而設置的製造設備的示意圖。請同時參考圖4與圖5，製造設備500包括一傳送帶510、一平板擠壓單元520、一滾壓單元530、一捲收單元540、溫度控制模組550以及一射出成型單元560。平板擠壓單元520配置在傳送帶510的入口處， 捲收單元540配置在傳送帶510的出口處，而射出成型單元560位在平板擠壓單元520之前。 Accordingly, FIG. 5 is a schematic view of a manufacturing apparatus provided corresponding to the manufacturing flow of FIG. 4 and a suitable material. Referring to FIG. 4 and FIG. 5 simultaneously, the manufacturing apparatus 500 includes a conveyor belt 510, a flat plate extrusion unit 520, a rolling unit 530, a take-up unit 540, a temperature control module 550, and an injection molding unit 560.

The take-up unit 540 is disposed at the exit of the conveyor belt 510, and the injection molding unit 560 is positioned before the flat plate extrusion unit 520.
首先在步驟410中，當射出成型單元560將一高分子聚合物502(本實施例中高分子聚合物502為上述之熱塑性彈性體或具有同等性質者)射出成型後，藉由平板擠壓單元520擠壓高分子聚合物502成一連續式板材504，此連續式板材504在步驟420藉由溫度控制模組550而被加熱，以使其溫度高於高分子聚合物502的玻璃轉換溫度(Glass transition temperature,Tg)，因而得以讓部分的連續式板材504因加熱而具有可變形的狀態。換句話說，藉由加熱而讓連續式板材504分隔為一基層506與一形成層505，並使基層506與形成層505之間存在不間斷的連續面505a。在此需說明的是，溫度控制模組550包括現有技術中具備加熱與冷卻的相關裝置，在此並不對其予以限制。 First, in step 410, after the injection molding unit 560 shoots a high molecular polymer 502 (the polymer 502 in the embodiment is a thermoplastic elastomer or the like), the flat pressing unit 520 is used. The extruded polymer 502 is formed into a continuous sheet 504 which is heated by the temperature control module 550 in step 420 to have a temperature higher than the glass transition temperature of the polymer 502 (Glass transition) Temperature, Tg), thus allowing a portion of the continuous sheet material 504 to have a deformable state due to heating. In other words, the continuous sheet material 504 is separated into a base layer 506 and a forming layer 505 by heating, and an uninterrupted continuous surface 505a exists between the base layer 506 and the forming layer 505. It should be noted that the temperature control module 550 includes related devices having heating and cooling in the prior art, which are not limited herein.
然後，在步驟430將加熱後的連續式板材504以滾壓單元530進行滾壓，以在形成層505滾壓出光學結構單元508，並由於滾壓單元530為一滾筒式模仁，因此便會將連續式板材504的形成層505滾壓出多個光學結構單元508，並因而成型出光學結構陣列100。 Then, in step 430, the heated continuous sheet material 504 is rolled by the rolling unit 530 to roll out the optical structural unit 508 at the forming layer 505, and since the rolling unit 530 is a drum type mold, The formation layer 505 of the continuous sheet 504 is rolled out of the plurality of optical structural units 508 and the optical structure array 100 is thus formed.
在本實施例中，滾壓單元530之光學結構圖案534，其可藉由精密切削(cutting)加工、精密電鑄(Electroforming)加工精密放電加工或是微鑄模(LIGA)製程，而形成突出於表面532的立體圖案。溫度控制模組550可為紅外線加熱燈管，或是在傳送連續式板材的傳送 帶510上，以電熱或水進行溫控。在本發明之另一未繪示的實施例中，更可直接同時加熱與滾壓連續板材，例如在滾壓單元之滾筒模仁上設置高低溫水路切換系統、電熱裝置與水路或者高溫油路與水路，即可同時加熱與滾壓連續板材。 In this embodiment, the optical structure pattern 534 of the rolling unit 530 can be formed by precision cutting, precision electroforming, precision electric discharge machining or micro-molding (LIGA) process. A three-dimensional pattern of surface 532. The temperature control module 550 can be an infrared heating lamp or can transmit a continuous plate. On the belt 510, temperature control is performed by electric heating or water. In another embodiment of the invention, the continuous plate is heated and rolled directly, for example, a high and low temperature water circuit switching system, an electric heating device and a water path or a high temperature oil circuit are arranged on the roller mold core of the rolling unit. With the waterway, it is possible to simultaneously heat and roll the continuous sheet.
進一步地說，在本實施例中是藉由溫度控制模組550將高分子聚合物502進行加熱，以利將其擠壓成連續式板材504後再以滾壓單元530滾壓出光學結構陣列100。在此並未限制形成層505與基層506之間的比例，凡讓連續式板材504的整體厚度與其上的光學結構陣列100能符合前述的尺寸要求者，皆可適用於本發明。 Further, in the embodiment, the high molecular polymer 502 is heated by the temperature control module 550 to be extruded into the continuous plate 504, and then rolled out of the optical structure array by the rolling unit 530. 100. The ratio between the formation layer 505 and the base layer 506 is not limited herein, and any embodiment in which the overall thickness of the continuous sheet material 504 and the optical structure array 100 thereon can meet the aforementioned dimensional requirements are applicable to the present invention.
接著，在步驟440中藉由溫度控制模組550冷卻連續式板材，使其溫度低於高分子聚合物502的玻璃轉換溫度以固化其上的光學結構陣列100。最後，於步驟450中以捲收單元540捲收連續式板材，以使其成為如圖1所繪示的卷狀產品10。之後，使用者便能依據所需物品的外形而對卷狀產品10進行裁切與組合。 Next, in step 440, the continuous sheet is cooled by the temperature control module 550 to a temperature below the glass transition temperature of the polymer 502 to cure the optical structure array 100 thereon. Finally, in step 450, the continuous sheet is taken up by the take-up unit 540 to make it a rolled product 10 as shown in FIG. Thereafter, the user can cut and combine the rolled product 10 according to the shape of the desired article.
據此，藉由上述的製造設備500與製作流程，得以製作出連續式且具有光學結構陣列100的卷狀產品10(標示於圖1)。此舉相較於現有逐次逐片的壓印技術而言，提供了較為經濟的生產方式並提高了生產效率。 Accordingly, the continuous product 10 having the optical structure array 100 (shown in FIG. 1) can be fabricated by the above-described manufacturing apparatus 500 and manufacturing process. This provides a more economical production method and improved production efficiency compared to the existing one-by-one embossing technology.
圖6為本發明之另一實施例的一種光學結構陣列的製作流程圖，在此以光固化透明高分子材料為例，需先說明的是，光固化透明高分子材料，例如是UV光硬化塑膠， 藉由UV光源照射起動化學連鎖反應，促使接著劑在數秒的時間內完成固化接合材質。光固化透明高分子材料的原理為在樹脂中加入光引發劑(或光敏劑)，經過吸收紫外線(UV)光固化設備中的高強度紫外光後，產生活性自由基或離子基，從而引發聚合、交聯和接續反應，使樹脂(UV)塗料、油墨、粘合劑等在數秒到幾分之間，由液態轉化為固態。此變化過程稱之為UV固化。光固化透明高分子材料是一種乾淨、環保、快速、提高生產效率的組裝膠合方式。 6 is a flow chart of fabricating an optical structure array according to another embodiment of the present invention.
