Description

擠壓成型裝置
本發明系關於一種成型裝置，特別涉及一種擠壓成型裝置。
導光板一般應用於液晶顯示器的背光模組，且順應小型化趨勢越來越薄。目前，導光板主要採用射出成型技術製造，過薄的導光板導致冷卻過快，使得網點等微結構難以完全成型導光板上，難以達到預定的光學效果。
有鑑於此，有必要提供一種能保證導光板的光學效果的擠壓成型裝置。
一種擠壓成型裝置，其包括一霧化輪、一網點輪、一注入結構、一導向結構及一棱鏡成型系統。所述霧化輪與所述網點輪相鄰設置，所述注入結構位於所述霧化輪與所述網點輪的上方。所述導向結構位於所述網點輪與所述棱鏡成型系統之間。所述棱鏡成型系統包括一塗佈系統、一棱鏡輪及一紫外光源。所述塗佈系統位於所述導向結構和所述棱鏡輪之間，所述紫外光源位於所述棱鏡輪的上方。所述注入結構用於收容一熔融體並將所述熔融體注入至所述霧化輪和所述網點輪之間，所述熔融體經過所述霧化輪和所述網點輪擠壓成型為一導光板，所述導光板包括一由所述霧化輪成型的霧面及一由所述網點輪成型的且與所述霧面相對的網點面。所述導向結構將所述導光板傳依次送至所述塗佈系統及所述棱鏡輪，所述塗佈系統在所述導光板的霧面上塗覆一層紫外膠。所述棱鏡輪對所述紫外膠進行壓印以形成一棱鏡結構，所述紫外光源用於對所述棱鏡結構進行固化。
相較於先前技術，本發明提供的擠壓成型裝置中霧化輪和網點輪通過對熔融體進行擠壓成型為導光板，所述導光板形成一霧面及一與所述霧面相對的網點面；另外，通過棱鏡輪和紫外光源對塗覆在霧面上的紫外膠進行壓印形成棱鏡結構；從而有效的保證了導光板的光學效果。

在所述導光板200的成型過程中，承載在所述注入結構30中的一熔融體32從所述注入口31注入至所述霧化輪10和所述網點輪20之間。所述熔融體32經過所述霧化輪10和所述網點輪20擠壓成型為所述導光板200。由於所述導光板200與所述網點輪20的黏附力大於與所述霧化輪10的黏附力，從而使成型的導光板200附著在所述網點輪20上。所述導光板200包括一由所述霧化輪10的霧化結構111成型的霧面201及一由所述網點輪20的網點結構211成型的網點面202，所述霧面201與所述網點結構211相對設置。所述導光板200在所述導向結構40中的兩個導向滾輪41之間的作用下被傳送至所述塗佈系統51，所述其中一塗佈滾輪512與所述導光板200的霧面201相接觸。所述塗佈滾輪512在所述導光板200的霧面201上塗覆一層紫外膠513。所述導光板200從所述棱鏡輪52和所述紫外光源53之間經過，所述導光板200與所述棱鏡輪52相接觸，所述棱鏡輪52對所述紫外膠513進行壓印以形成一棱鏡結構203，所述紫外光源53對所述棱鏡結構203進行固化。所述導光板200經過所述棱鏡成型系統50後傳送至所述保護膜貼合系統60，所述導光板200從所述上貼合部61和所述下貼合部62之間通過。所述上貼合部61和所述下貼合部62在所述導光板200的網點面202和棱鏡結構203上貼附保護膜63。所述剪切裝置70將所述導光板200剪切至合適的尺寸。
如圖3所示為本發明第二實施方式提供的一種擠壓成型裝置100a。第二實施方式提供的擠壓成型裝置100a與第一實施方式提供的擠壓成型裝置100的區別在於：所述擠壓成型裝置100a還包括一冷卻輪80，所述冷卻輪80設置在所述網點輪20與所述導向結構40之間。所述冷卻輪80用於對所述導光板200進行冷卻。
本發明提供的擠壓成型裝置中霧化輪和網點輪通過對熔融體進行擠壓成型為導光板，所述導光板形成一霧面及一與所述霧面相對的網點面；另外，通過棱鏡輪和紫外光源對塗覆在霧面上的紫外膠進行壓印形成棱鏡結構；從而有效的保證了導光板的光學效果。
