201137464 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種偏光膜貼合裝置及具有該偏光膜 貼合裝置之液晶顯示裝置製造系統。 【先前技術】 過去，液晶顯示裝置被廣泛地製造。為了控制光線的 穿透或遮斷，用於液晶顯示裝置的基板(液晶面板)通常會 貼合有偏光膜。偏光膜會與該吸收軸呈垂直般貼合。 作為在基板上貼合偏光膜的方法可例如為Chip to Panel方式，其係對應基板尺寸將偏光膜切割後進行貼 合。但是’該方式須針對基板一片片地貼合偏光膜，導致 生產效率低的缺點。另一方面，作為其它方式則可例如為 Roll to Panel方式，其係以輸送滚筒供給偏光膜而連續地 貼合至基板。依該方法能以高生產效率進行貼合。 專利文獻1中的光學顯示裝置之製造系統揭露了一種 作為Roll to Panel方式的範例。上述製造系統係在將光學 薄膜(偏光膜）貼合至基板上方之後旋轉基板，再從下方貼 合偏光膜。 專利文獻1 :曰本專利特許第4307510號公報(2009 年8月5曰公開）」。 但是’該習知裝置具有以下的問題。 首先’針對基板來貼合偏光膜之情況，為了避免灰塵 等異物混入貼合面中，通常會在無塵室中進行作業。接 201137464 著，無塵室係經過空氣整流處理。為了抑制由於異物而導 致良率的減少，則必須要在經降流式整流處理之狀態下來 斜對基板貼合偏光膜。 關於這點，專利文獻1的製造系統係針對基板自上方 及下方貼合偏光膜的結構。但是，自偏光膜上方進行貼合 之情況’則可能具有因偏光膜妨礙氣流（降流式）而使得流 向基板之整流環境惡化的缺點。作為從偏光膜上方進行貼 合的範例，第9a圖及第9b圖顯示上貼型之製造系統中的 氣流速度向量。在第9a圖及第9b圖中：A區域係設置有 捲出偏光膜用之捲出部的區域；B區域主要是偏光膜通過 的區域；C區域係設置有捲取從偏光膜所去除之剝離膜用 的捲取部。 又’自 HEPA(High Efficiency Particulate Air)過濾器 4〇供給潔淨空氣。另外’第9a圖中，由於設置有能讓潔 淨空氣通過之格柵41 ’氣流會經由格柵41朝垂直方向移 動。另一方面，第9b圖中’由於未設置有格柵41，氣流 在接觸第9b圖中最下部的地板之後，便會沿著地板移動。 第9a圖及第9b圖中，2F(2樓)部分設置有a區域至 C區域，故偏光膜會妨礙來自HEPA過濾、器40的潔淨空 氣。因此，難以產生相對於通過2F部分之基板並朝垂直 方向的氣流。對此，會形成水平方向氣流向量較大（向量 的密度較高）的狀態。換言之，係會形成整流環境惡化的 狀態。 本發明有鑑於前述習知問題，其目的為提供一種不會 201137464 妨礙整流環境的偏光膜貼合裝置以及具有該裝置之液晶 顯示裝置製造系統。 【發明内容】 為了解決刖述習知問題，本發明之偏光膜貼合裝置係 包含有：第一基板搬送機構，係將長方形基板以長邊或短 邊沿著搬送方向之狀態下進行搬送；第一貼合部，用於將 偏光膜貼合至該第一基板搬送機構之基板的下方；反轉機 構，用於將該第一基板搬送機構所搬送的基板反轉並配置 至第一基板搬送機構；第二基板搬送機構，用於將該基板

基板的下方’沿著反轉機構中之基板反轉部的反轉軸進行 迴轉藉以反轉基板，並可改變搬送方向所相對的長邊及短 邊。然後，便可由第二貼合部來將偏光膜貼合至基板的下 方。即，可針對基板之兩面從下方來貼合偏光膜，故不會 妨礙整流環境。又，由於反轉機構之動作係為一單纯的動 作’加工時間較短。因此，可實現加工時間較短的貼合作 業。再者，該第一基板搬送機構及第二基板搬送機構係將 基板朝同-方向搬送。換言之，其不具有L型等複雜構 造。因此，本發明之偏光膜貼合裝置的設置非常簡便，並 • 具有良好之面積效率。 ，又，較佳地本發明之偏光膜貼合裝置係將該第一基板 搬送機構及該第二基板搬送機構配置於一直線上，第一美 板搬适機構位於第二基板搬送機構一侧具有一端部，相ς 該端部之第一基板搬送機構搬送方向且沿著水平兩方向 而各自具有二對的基板載置部及該反轉機構；該; 设有從該端部將該基板朝向該基板載置部搬送的搬送機 構；讀反轉機構係讓各自搬送至該基板載置部的基板 並配置至第二基板搬送機構。 依據上述之結構’由於具有二個反轉機構，於每單位 . _中可對基板進行2倍處理。藉此，每單位時間中可將 更多之基板進行反轉，故可縮短加工時間。再者，由 一基板搬送機構及第二基板搬送機構配置於一直線上 提供面積效率更優良之構造的偏光膜貼合裝置。 又，本發明之偏光顏合裝置係較佳具有搬送偏光膜 2〇1137464 第一膜搬送機構及第二膜搬送機構，該第一膜搬送機 有.用於捲出由剝離膜所保護之偏光膜的複數個捲 ^用於將偏光膜切斷用的切斷部、用於從偏光膜上將 剝離膜去除的去除部、及用於將被去除後之該剝離膜捲取 的複數個捲取部；該第二膜搬送機構處具有：用於將由剝 離膜所保護之偏光膜捲出用的複數個捲出部用於將偏光

藉此，由於具有複數個捲出部及捲取部，當一侧之捲 出部中偏光膜原料之殘餘量變少的情況，可將該原料連接 至設置於另-侧捲出部的原料。其結果，無需停止偏光膜 之捲出’可續行作業，故可提高生產效率。 又，本發明之偏光膜貼合裝置較佳地具有在藉由該第 一貼合部來將偏光膜貼合至基板下方之前洗淨基板用的 洗淨部，且該第一基板搬送機構係以基板之短邊沿著搬送 方向之狀態下來搬送基板。 藉此’可於基板之長邊相對於基板搬送方向呈垂直的 狀態下，藉由洗淨部來進行基板之洗淨。即，可縮小基板 8 201137464 > 沿搬送方向的距離，故可縮短洗淨所需加工時間。其結 果’可提供生產效率更加優良之偏光膜貼合裝置。 又，較佳地本發明之偏光膜貼合裝置中，該第一膜搬 送機構及該第二膜搬送機構處具有：缺陷檢出部，係可檢 測出從第一捲出部所捲出之偏光膜上附著的缺陷顯示；貼 合迴避部，係判別出該缺陷顯示而停止該基板之搬送；以 及回收部，係將迴避而未貼合至基板的偏光膜回收。 依該缺陷檢出部、貼合迴避部及回收部，可避免將具 * 有缺陷之偏光膜與基板進行貼合，故可提高良率。 ， 本發明之液晶顯示裝置製造系統具有：上述之偏光膜 貼合裝置；以及貼合偏差檢測裝置，用於檢查由該第二貼 合部元成偏光膜貼合後之基板上的貼合偏差。 藉此’可檢查出貼合好偏光膜後之基板所產生的貼合 偏差。 又’本發明之液晶顯示裝置製造系統較佳地具有遴選 搬送裝置，係藉由該貼合偏差檢測裝置之檢查結果來判斷 是否有貼合偏差’根據該判斷結果來對已貼合好偏光膜之 基板進行遴選。 ， 藉此’當貼合好偏光膜之基板產生貼合偏差之情況， . 讦迅速地遴選為不良品，可縮短加工時間。 又’較佳地本發明之液晶顯示裝置製造系統具有：偏 光族貼合裝置；以及貼合異物自動檢測裝置，係檢查由該 偏光膜貼合裝置之第二貼合部完成偏光膜貼合後之基板 上的異物。 201137464 藉此’可檢查混入至貼合好偏光膜之液晶面板中是否 存在異物。 又’較佳地本發明之液晶顯示裝置製造系統具有遴選 搬送裝置’係藉由該貼合異物自動檢測裝置之檢查結果來 判斷是否存在異物’根據該判斷結果來對已貼合好偏光膜 之基板進行遴選。 藉此，當貼合好偏光膜之液晶面板中混入有異物之情 況’可迅速地遴選為不良品，可縮短加工時間。 又，較佳地本發明之液晶顯示裝置製造系統具有貼合 異物自動檢測裝置，係檢查由該第二貼合部完成偏光膜貼 合後之基板上的異物，且具有遴選搬送裝置，係藉由該貼 合偏差檢測裝置之檢查結果與該貼合異物自動檢測裝置 之檢查結果來判斷是否存在貼合偏差與異物，根據該判斷 結果來對已貼合好偏光膜之基板進行遴選。 藉此，當貼合好偏光膜之液晶面板中產生了貼合偏差 與混入異物之情況時，可迅速地將其遴選為不良品，而可 縮短加工時間。 如上所述，本發明之偏光膜貼合裝置，該第一基板搬 送機構及第二基板搬送機構係將基板朝同一方向進行搬 送，且具有反轉機構，係能吸附以長邊或短邊沿著第一某 板搬送機構搬送方向的基板並進行反轉，使其形成以短邊 或長邊沿著第二基板搬送機構搬送方向的狀態；該反轉機 構係具有用於吸附基板的吸著部、及連接至吸著部的基板 反轉部，該基板反轉部係沿著反轉軸進行迴轉藉以反轉基 201137464 板；該反轉轴係位在下述（1)的面内，且位在（2)的垂直位 置。（1)包含通過第一基板搬送機構之基板的中心以及與該 基板搬送方向垂直之直線作為基準而傾斜45。的直線。（2) 位在相對於第一基板搬送機構之基板的垂直位置處。 因此’藉由該反轉機構來反轉基板，同時可改變相對 於搬送方向之長邊及短邊。藉此，針對基板之兩面，可從 下方貼合偏光膜，故不會妨礙整流環境。又，由於反轉機 構之動作為一單純動作，加工時間較短。因此，可實現加 工時間較短的貼合。再者，該第一基板搬送機構及第二基 板搬送機構係朝向同一方向而設置。換言之，其不具有L 型形狀等複雜構造。因此，本發明之偏光膜貼合裝置具有 設置非常簡便且面積效率優良的效果。 【實施方式】 以下雖根據第1圖至第8圖來說明本發明之一實施態 樣，但本發明並非限定於此。首先，說明本發明之液晶顯 示裝置製造系統的結構如下所述，其中，液晶顯示裝置製 造系統包含有本發明之偏光膜貼合裝置。 第1圖係液晶顯示裝置製造系統的剖面圖。如第1圖 所示，液晶顯示裝置製造系統100為二層結構^ 1F(1樓) 部份為膜搬送機構50。2F(2樓)部份則為包含有基板搬送 機構（第一基板搬送機構及第二基板搬送機構)的偏光膜貼 合裝置60。 <膜搬送機構> 201137464 首先，說明有關膜搬送機構50。膜搬送機構5〇之功 用在於將偏光膜(偏光板)捲出而搬送至軋親6、6a及乳輥 =、16a，並捲取不需要之剝離膜。另一方面，偏光膜貼 合裒置60之功用則在於將藉由膜搬送機構5〇所捲出之偏 光膜對於基板(液晶面板)5進行貼合。 膜搬送機構50具有第一膜搬送機構51及第二膜搬送 機構52。第-膜搬送機構51係用以將偏光膜搬送至最先 將偏光膜貼合至基板5下方的軋輥6、以處。另一方面， 第二膜搬送機構52 _以將偏光膜搬送至反轉後之基板 5的下方處。 第一膜搬送機構51具有：第一捲出部卜第二捲出部 la第捲取部2、第一捲取部2a、半切器（halfcutter)3、 刀刀（knifeedge)4、及缺陷膜捲取滚筒7、7a。第一捲出部 1處設置有偏光膜料卷，可將偏光膜捲出。可使用習知的 偏光膜作為該偏光膜。具體來說，可使用一種在聚乙烯醇 膜上經碘等染色且朝向一軸方向延伸之膜等偏光膜。該偏 光膜之厚度雖無特別限定，但較佳為使用5μιη以上、 400μπι以下之偏光膜者。 該偏光膜料卷中，吸收軸方向係位於流程方向（MD方 向）上。該偏光膜中係藉由剝離膜以保護黏著劑層。可使 用聚酯膜（polyester film)、聚對苯二甲酸乙二酯 (polyethylene terephthalate)膜等作為該剝離膜（亦可稱作 保護膜或分離膜separator)。該剝離膜之厚度雖無特別限 定’但較佳為使用5μιη以上、ΙΟΟμιη以下之剝離膜者。 12 201137464 關於液晶顯示裝置製造系統100，由於具有二個捲出 部及對應捲出部之二個捲取部，當第一捲出部1之料卷殘 量變少時，可將設置於第二捲出部la之料卷連結至第一 捲出部1之料卷。其結果，無需停止偏光膜之捲出，即可 續行作業。因此，藉由本結構可提高生産效率。另外，只 需各具有複數個該捲出部及捲取部即可，故當然亦可具有 三個以上的捲出部及捲取部。 半切器（切斷部）3會將受剝離膜保護之偏光膜（由偏光 ' 膜、黏著劑層及剝離膜所構成之膜層積體）半切斷（half • cut)，以將偏光膜及黏著劑層切斷。半切器3係可使用習 知組件。具體而言，可例如為刀刃、雷射切割器等。藉由 半切器3來將偏光膜及黏著劑層切斷後，再藉由刀刃（去 除部)4來將剝離膜從偏光膜處去除。 偏光膜與剝離膜之間處塗佈有黏著劑層，將剝離膜去 除後，黏著劑層會殘留於偏光膜側。該黏著劑層並無特別 限定，可例如為丙烯系、環氧系、聚胺脂系等黏著劑層。 黏著劑層之厚度雖無特別限制，但通常為5〜40μιη。 另一方面，第二膜搬送機構52係與第一膜搬送機構 • 51具相同的結構，具有第一捲出部11、第二捲出部11a、 第一捲取部12、第二捲取部12a、半切器13、刀刃14及 缺陷膜捲取滾筒17、17a。關於命名為相同名稱之組件， 即代表其功用與第一膜搬送機構51所具備者相同。 作為一較佳實施態樣，液晶顯示裝置製造系統100具 有洗淨部71。在藉由軋輥6、6a將偏光膜貼合至基板5 13 201137464 下方之前，洗淨部7〗係用以將基板5洗淨。洗淨部η 使用由喷射洗淨液之喷似刷毛#所構成的習 即可。洗淨部7i係將即將要貼合之基板5洗淨， 在基板5之附著異物較少之狀態下進行貼合。 此 其次，參照第2圖來說明刀刀4。第2圖 裝置製造系統100中之軋輥6吻周邊部份的剖面 2圖顯示基板5從左方向右搬送之情 式中未顯示，以下㈣）的偏光膜 來。偏光膜5a具有剝_ 5b，藉由半切器3 = 5a及黏著劑層切斷，但不會將剝離膜讣切斷 、 於剝賴5b側設置有刀刃4。刀刃4係 ° 剝離用的刀刃狀组件，使得與偏光膜5a之接著、 剝離膜5b會沿著刀刃4而被剝離。 力較低的 然後，剝離膜5b貝會被第1圖之第一捲取部2所捲 取。另外，村取代㈣，制藉由㈣ 膜的結構。此時，相同於搽敌邱甘尨个怖取求J離 罾私1以 其係藉由將黏著滾筒設 置於一位置處，可提高剝離膜之捲取效率。 /其次，㈣偏光膜貼合裝置⑼。偏光難合裝置6〇 係搬送基板5,並將藉由馳送機構5()所搬送*來的偏光 膜貼合至基板。圖中雖未顯示，於偏細貼合裝置60中， 面向基板5之上方而供給有潔淨空氣。即，進行降流式整 流。藉此’能在穩定狀態下進行基板5之搬送及貼合。 <偏光臈貼合裝置〉 偏光膜貼合敦置60係設置於膜搬送機構50上部處。 201137464 藉此’可達成液晶顯示裝置製造系統100之空間節省。圖 中雖未顯示，但於偏光膜貼合裝置60處設置有基板搬送 機構’其係具有輸送滚筒（conveyor roll)，藉以將基板5 朝搬送方向進行搬送（以下於第5a圖至第5d圖中之所述 第一基板搬送機構61、第二基板搬送機構62係相當於基 板搬送機構）。 液晶顯示裝置製造系統100中，從左側將基板5搬送 而來，然後，於圖中右侧，即，從第一膜搬送機構51上 部朝第二膜搬送機構52上部進行搬送。於膜搬送機構5〇 與偏光膜貼合裝置60之間處’各自具有作為貼合部的軋 輕6、6a(第一貼合部)及軋輥16、16a(第二貼合部）。軋輥 6、6a及16、16a係用以將已去除剝離膜後之偏光膜貼合 至基板5下方的組件。另外’為了從下方將偏光膜貼合至 基板5之兩面處’於軋輥6、6a進行貼合之後，再藉由反 轉機構65來反轉基板5。關於反轉機構65詳如後述。 朝向軋輥6、6a搬送之偏光膜會隔著黏著劑層而貼合 至基板5的下方處。作為札概6、6a，可分別採用壓著滚 筒' 加壓滾筒等習知結構。又，軋親6、6a於貼合時之壓 力及溫度可適當地進行調整。軋輥16、16a之結構亦相同。 另外’圖中雖未顯示’但液晶顯示裝置製造系統1〇〇之較 佳結構中，在第一捲出部1至半切器之間的位置具有缺陷 標示（Mark)檢出部，而可檢測出具有缺陷之偏光膜的結 構。 另外，關於該缺陷標示係在製作偏光膜料卷時進行檢 15 201137464 測而會賦予缺陷標示，亦或， 偏光膜上，該缺陷標示賦予部標，予部賦予至 為靠近第-捲出部n或第二捲:部二：出部係更 予部係由攝影機、圖像處理裝置及缺陷標示示賦 成二首先’用該攝影機來進行偏光膜之攝 : 影情報進行處理’便可檢查出是否有缺陷。具 缺陷可例如為灰塵等異物、魚眼(fisheye)等。ς 有缺陷之情況，便藉由缺陷標示形成部來於偏光膜上形成 缺陷標示。缺陷標示可使用墨水等來標記。 再者’圖中未顯示之貼合回避部會藉由攝影機來辨別 出該標記’將停止訊號傳送給偏光膜貼合裝置6〇以停止 基板5之搬送。然後’被檢出有缺陷之偏光膜便不會藉由 軋輥6、6a進行貼合，而會被缺陷膜捲取滾筒（回收部）7、 7a所捲取。藉此，可避免讓基板5與具有缺陷之偏光膜相 貼合。只要具有該系列之結構，由於可避免讓具有缺陷之 偏光膜與基板5相貼合’故可提高良率，係為較佳之實施 態樣。缺陷檢出部及貼合回避部係可使用習知之檢查感測 器。 如第1圖所示，藉由反轉機構65來讓基板5呈反轉 狀態之後’將基板5搬送至軋輥16、16a。接著，將偏光 膜貼合至基板5下方。其結果’可將偏光膜貼合至基板5 之兩面，而形成於基板5兩面處貼合有二片吸收軸相異之 偏光膜的狀態。然後’依需要對基板5之兩面進行檢查， 檢查是否有貼合偏差。通常’該檢查係採用具有攝影機之 201137464 檢查部等來進行之結構。 如上述之液晶顯示裝置製造系統議中，將偏光膜貼 合至基板5時，係從基板5下方進行貼合之結構，故不會 妨礙基板5之整流環境。因此，亦可防止異物混入基板$ 之貼合面，能更正確地進行貼合。 第3a圖及第3b圖係顯示近似本發明之下貼型製造系 統中之氣流速度向量。第3a圖及第3b圖中，區域a =設 置有捲出部之區域，區域B主要為偏光膜通過之區域，區 域C係设置有捲取部等之區域。又，會從η 40供給潔淨空氣。另外，第3a圖中，由於設置有能讓潔 淨空氣通過之格柵41(grating)，經由格柵41， 直方向移動ϋ面’第3b圖中，由於未設置有格樹 41，氣流在接觸地板之後，便會沿地板移動。 由於第3a圖和第3b圖所示液晶顯示裳置製造系統為 下貼型’不同於如第9a圖和第9b圖中所示由於偏光膜而 妨礙來自HEPA過濾器40的氣流。因此，氣流向量之方 向幾乎均朝向基板方向，可說是能達成無塵室之較佳整流 環境。第3a圖中設置有格栅41，第3b圖中則未設置，但 兩者皆同樣為較佳狀態。另外，第3a圖及第3b圖與第9a 圖及第9b圖中，雖然基板搬送機構係呈水平，但並非是 設置呈一連串之構造。因此，於基板搬送機構之間處可容 氣流通過之結構。基板係在藉由後述之反轉機構而受保持 之後，傳送於基板搬送機構之間處的結構。 又，液晶顯示裝置製造系統100中，首先，以長邊朝 17 201137464 前（長邊與搬送方向垂直）來搬送基板5，然後，以短邊朝 前（短邊與搬送方向垂直）來搬送之結構。 <反轉機構> 反轉機構65係可將短邊或長邊沿著搬送方向的基板 5，改變其配置而形成長邊或短邊沿著搬送方向的狀態。 第4a圖至第4c圖係藉由反轉機構65來將基板5反轉之 過程的立體圖。 第4a圖係吸附由第一基板搬送機構所搬送而來之基 板5的狀態。第4b圖係移動基板5的過程，第4c圖係藉 由第二基板反轉機構來將基板5反轉後的狀態。另外，為 了方便圖示，第4a圖至第4c圖中省略繪出第一基板搬送 機構及第二基板搬送機構，留待於第5a圖至第5d圖詳述 如後。 如第4a圖所示，反轉機構65係具有吸著部66、基板 反轉部67及昇降部68。吸著部66係對基板5表面造行吸 附之組件。藉由吸著部66讓基板5表面保持於吸著部66 處。吸著部66可使用習知的吸著部，例如，可使用空氣 吸取式吸著部。 基板反轉部67係連結至吸著部66，以連接吸著部66 及昇降部68之結構。基板反轉部67係藉由以反轉軸Μ 為軸進行迴轉之方式來反轉基板5的組件。第4a圖中， 基板反轉部67之昇降部68侧會形成朝向基板5而相對於 反轉軸Μ朝垂直方向延伸之形狀。再者，基板反轉部67 之吸著部66側則形成通過第一基板搬送機構之基板5中 201137464 心，而沿著與基板5長邊(搬送方向）呈平行之直線彎曲約 40°的形狀。第4a圖所示基板反轉部67之形狀僅為一範 例，並非限定為該形狀。作為其他形狀，例如，亦可從昇 降部68側朝吸著部66側彎曲之形狀，以取代如基板反轉 部67般之彎曲形態。又，亦可採用如機械手臂般具有複 數個可動部之構造。 基板反轉部67係將可進行迴轉之可動部設置於昇降 部68處之結構。該可動部係沿著反轉轴Μ而配置，而可 " 讓基板反轉部67沿著反轉軸Μ進行迴轉的構造。 • 反轉軸Μ係（1)位在一平面上，該平面係包含有通過 第一基板搬送機構之基板5的中心以及與基板5的搬送方 向垂直之直線作為基準而傾斜45°的直線，並且與基板5 垂直（參考第5a圖）；（2)且位在與基板5水平之位置（參考 第4a圖）上。反轉軸Μ亦可位於上述平面上，且可使基板 5被移動到垂直方向。 基板反轉部67係可經由可動部而沿著反轉軸Μ進行 迴轉的結構，但只要是能沿著反轉軸Μ進行迴轉之結構 即可，該結構並無特別限定。例如，基板反轉部67具有 迴轉軸構造，當該迴轉轴構造之軸沿著反轉軸Μ進行迴 * 轉的同時，使得基板反轉部67整體進行迴轉的構造。基 板反轉部67之迴轉運動係例如藉由馬達（圖中未顯示）等 驅動裝置來進行。 基板反轉部67係能藉由以反轉轴Μ為轴迴轉一圈來 反轉基板5。所謂反轉係指讓基板5迴轉至其相反面，換 201137464 言之，讓基板5之表面轉為背面。 昇降部68為具有彎曲部之手臂狀，可藉由縮小手臂 之角度來讓基板反轉部67上昇。另一方面，亦可藉由增 加手臂之角度來讓基板反轉部67下降。在未搬送基板5 時’係將吸著部66設置於基板5之更上方側，以避免接 觸至基板5。接著，在搬送基板5時，藉由昇降部68讓基 板反轉部67下降，吸著部66亦會下降，便可藉由吸著部 66來吸附基板5。又，將基板5反轉之後，解除吸著部66 之吸附，於解除後藉由昇降部68來移動基板反轉部67而 · 讓吸著部66從基板5處分離。 . 使用第4a圖至第4c圖來說明反轉機構65之動作。 首先，第4a圖中，顯示當基板5之短邊沿搬送方向之情 況。藉由吸著部66來吸附基板5表面後，沿著反轉軸M 來迴轉基板反轉部67。第4a圖中，雖然係藉由吸著部％ 來吸附基板5之中心附近處，但只要能固定而使基板5不 會於迴轉時掉落即可，吸附位置並無特別限定。又，吸附 位置亦不限定於4個位置處，當然可適當地增減。 其次，從第4a圖之狀態，讓基板反轉部67沿著反轉 軸Μ朝基板表面側進行迴轉。第4b圖係顯示基板反轉部 ， 67相對於第4a圖中（第一基板搬送機構中）之基板5迴轉 . 9〇。後的狀態。經過第4b圖之狀態’繼續迴轉基板反轉部 67而使基板5反轉如第4c圖所示。 如上所述，藉由反轉機構65之一次迴轉動作，便可 改變基板5之短邊及長邊方向而將其反轉。即，不需複雜 20 201137464 之迴轉動作，能以較短之加工時間（Tact Time)來進行基板 5之反轉。以結果而言，能以較短之加工時間來進行包含 反轉之基板5的偏光膜貼合作業。 另外，第4a圖至第4c圖中，為了讓基板5朝搬送方 向移動，故相對於第4a圖之基板5而將基板反轉部67設 置於搬送方向側。藉此，如第4c圖所示，於第二基板搬 送機構上，能在使基板5更加朝向搬送方向移動之狀態來 進行反轉。藉此，能以更短之加工時間來進行包含反轉操 _ 作之兩面貼合作業。 * 第5a圖至第5d圖係對應於第4a圖至第4c圖之基板 5於迴轉過程的俯視圖。第5a圖至第5d圖中顯示有第一 基板搬送機構61及第二基板搬送機構62。第一基板搬送 機構61及第二基板搬送機構62具有輸送滚筒（圖中未顯 示）。第一基板搬送機構61及第二基板搬送機構62係將 基板5朝同一方向進行搬送。因此，第一基板搬送機構61 及第二基板搬送機構62係沿著搬送方向呈直線狀結構。 換言之，其不具有L形等複雜構造。因此，本發明之偏光 膜貼合裝置60的設置非常簡便，且為面積效率優良的構 * 造。 * 如參照第4a圖至第4c圖之說明，首先，如第5a圖 所示1藉由吸著部66來保持基板5表面。其次，如第5b 圖所示，沿著反轉軸Μ之方向，讓基板反轉部67迴轉90° 而使基板5呈垂直狀態。最後，如第5c圖所示，使基板 反轉部67繼續沿著反轉轴Μ之方向進行迴轉，以將基板 21 201137464 5反轉。反轉基板5時，基板5係設置於輸送滚筒（圖未示) 處，基板反轉部67不會接觸至輸送滚筒。因此’反轉機 構65係位於基板5之下方侧。 然後，藉由解除吸著部66之吸附以解除基板5之保 持，由第二基板搬送機構62來搬送基板5。接著，反轉機 構65會回到第5a圖之位置，以同樣之動作來反轉依序搬 送而來的其他基板5。 如上述之反轉機構65，於吸著部66之吸附後，藉由 基板5之一次動作來讓基板5反轉，並改變相對於搬送方 向之長邊及短邊。於反轉動作之前，於基板5下方貼合偏 光膜’於進行該反轉動作之後，便可對反轉後之基板5的 下方再次貼合偏光膜。（1)可如上述地對基板5兩面從下方 貼合偏光膜’（2)該反轉動作為單純之迴轉動作，且單次之 動作加工時間短。因此，可達成不會妨礙整流環境，且加 工時間短的貼合作業。 另外，基板反轉部67之反轉動作係單一次動作，但 即便是包含有於軸作前後昇降基板5 _作及/或調整 基板反轉部67位置的動作，亦包含於本發明之反轉機構 65的動作中。 第5a圖至第5d圖中，第一基板搬送機構61及第二 基板搬送機構62係將基板5朝同—方向進行搬送，且 相互鄰接之構造。如第5e圖中所^此仙為藉由基板 反轉部67而改變基板5相對於搬送方向之短邊 置，搬送反轉後基板5之第二基板搬送機構62與第邊^ 22 201137464 板搬送機構61的搬送方向不會在—直線上，而會產生偏 移。另外，第一基板搬送機構61及第二基板搬送機構62 不一定要相互鄰接，亦可於第一基板搬送機構61及第二 基板搬送機構62之間設ί有間隔。 如第4a圖至第4c圖所述’為了讓基板5朝搬送方向 移動，故相對於反轉前之基板5而將基板反轉部67設置 於搬送方向側。但是，當反轉機構65之配置等有限制之 . 情況時，亦可如第5d圖中所示設置反轉機構65❶此時， . 雖無法讓基板5朝搬送方向移動，但可對應於反轉機構65 之配置等的限制。 第6圖係偏光膜貼合巢置6〇之變化實施例的俯視 圖。該變化實施例中的變化之處為：（1)具有二個反轉機構 65 ’（2)於第一基板搬送機構61兩側具有二個基板載置部 61a ’（3)第一基板搬送機構61及第二基板搬送機構62配

該變化實施例中，二個基板載置部61a係各自沿第一 基板搬送機構61之水平兩方向而設置，反轉後之基板5 便會沿著第一基板搬送機構61之搬送方向而配置。因此， 可將第一基板搬送機構61及第二基板搬送機構62配置於 一直線上。 依該變化實施例，（1)由於具有二個反轉機構65，於 每單位時間可對基板5進行2倍之處理。藉此，可於每單 位時間將更多的基板5反轉，可縮短加工時間。（2)再者，

[Prior Art] In the past, liquid crystal display devices have been widely manufactured. In order to control the penetration or interruption of light, a substrate (liquid crystal panel) used for a liquid crystal display device is usually bonded with a polarizing film. The polarizing film will conform to the axis of the absorption axis. The method of bonding the polarizing film to the substrate can be, for example, a Chip to Panel method in which the polarizing film is cut and bonded in accordance with the substrate size. However, this method is required to adhere the polarizing film to the substrate one by one, resulting in a disadvantage of low production efficiency. On the other hand, as another method, for example, a Roll to Panel method in which a polarizing film is supplied by a transport roller and continuously bonded to a substrate can be used. According to this method, the bonding can be performed with high production efficiency. The manufacturing system of the optical display device in Patent Document 1 discloses an example of the Roll to Panel method. In the above manufacturing system, after the optical film (polarizing film) is attached to the upper side of the substrate, the substrate is rotated, and the polarizing film is bonded from below. Patent Document 1: Japanese Patent Laid-Open No. 4307510 (published on August 5, 2009). However, the conventional device has the following problems. First, in the case where the polarizing film is bonded to the substrate, in order to prevent foreign matter such as dust from entering the bonding surface, work is usually performed in the clean room. Connected to 201137464, the clean room is air rectified. In order to suppress the decrease in the yield due to the foreign matter, it is necessary to laminate the polarizing film obliquely to the substrate in the state of the downflow rectification treatment. In this regard, the manufacturing system of Patent Document 1 has a structure in which a polarizing film is bonded to the substrate from above and below. However, the case where the film is bonded from above the polarizing film may have a disadvantage that the rectifying environment flowing to the substrate is deteriorated because the polarizing film interferes with the air flow (downflow type). As an example of bonding from above the polarizing film, Figs. 9a and 9b show the airflow velocity vector in the above-described manufacturing system. In Fig. 9a and Fig. 9b, the area A is provided with a region for winding up the winding portion for the polarizing film; the region B is mainly the region through which the polarizing film passes; and the C region is provided with the winding removed from the polarizing film. A take-up portion for a release film. In addition, clean air is supplied from the HEPA (High Efficiency Particulate Air) filter. Further, in Fig. 9a, the airflow of the grille 41' through which the clean air passes is moved in the vertical direction via the grille 41. On the other hand, in Fig. 9b, since the grille 41 is not provided, the airflow moves along the floor after contacting the lowermost floor in Fig. 9b. In Fig. 9a and Fig. 9b, the 2F (2nd floor) portion is provided with a region to the C region, so that the polarizing film interferes with the clean air from the HEPA filter. Therefore, it is difficult to generate a gas flow in a direction perpendicular to the substrate passing through the 2F portion. In this regard, a state in which the horizontal airflow vector is large (the density of the vector is high) is formed. In other words, a state in which the rectification environment deteriorates is formed. The present invention has been made in view of the above conventional problems, and an object thereof is to provide a polarizing film laminating apparatus which does not interfere with a rectifying environment, and a liquid crystal display device manufacturing system having the same. In order to solve the conventional problem, the polarizing film bonding apparatus of the present invention includes a first substrate transfer mechanism that transports a rectangular substrate in a state in which a long side or a short side is along a transport direction. a bonding portion for bonding the polarizing film to the lower side of the substrate of the first substrate transfer mechanism, and a reversing mechanism for reversing the substrate transported by the first substrate transfer mechanism to the first substrate transfer a second substrate transfer mechanism for transporting the substrate in a state in which the short side or the long side is along the transport direction; and a second bonding portion for bonding the polarizing film to the second substrate transfer mechanism a lower surface of the substrate; wherein the first substrate transfer mechanism and the second substrate transfer mechanism transport the substrate in the same direction, and have a reversing mechanism for adsorbing the long substrate or the short side along the first substrate The substrate in the transport direction of the mechanism is reversed to form a state in which the short side or the long side is along the transport direction of the second substrate transport mechanism, and the reversing mechanism has a substrate for adsorbing the substrate. a absorbing portion and a substrate inverting portion connected to the absorbing portion, wherein the substrate inverting portion is rotated along the inversion axis to invert the substrate, wherein the inversion axis is in a plane of the following (1), and Positioned in the vertical position of (2). 〇) The substrate 45 including the substrate transfer mechanism and the line perpendicular to the substrate transfer direction are inclined 45. Straight line. (2) Positioned at a vertical position with respect to the substrate of the first substrate transfer mechanism. In the above aspect of the invention, the polarizing film is bonded to the lower side of the 6 201137464 substrate by the first bonding portion, and the substrate is rotated along the inversion axis of the substrate inverting portion in the reversing mechanism to reverse the substrate. Change the long side and short side of the transport direction. Then, the polarizing film can be attached to the lower side of the substrate by the second bonding portion. In other words, since the polarizing film can be bonded to the both surfaces of the substrate from below, the rectifying environment is not hindered. Further, since the operation of the reversing mechanism is a simple operation, the processing time is short. Therefore, it is possible to achieve a close cooperation process with a short processing time. Further, the first substrate transfer mechanism and the second substrate transfer mechanism transport the substrates in the same direction. In other words, it does not have a complicated structure such as an L-shape. Therefore, the polarizing film laminating device of the present invention is easy to set up and has a good area efficiency. Further, preferably, in the polarizing film bonding apparatus of the present invention, the first substrate transfer mechanism and the second substrate transfer mechanism are disposed on a straight line, and the first US plate transfer mechanism is located on the second substrate transfer mechanism side. The one end portion has two pairs of substrate mounting portions and the reversing mechanism in the first substrate transfer mechanism transport direction of the end portion and in the horizontal direction; the substrate is oriented from the end portion The transport mechanism that transports the substrate mounting portion and the read/reverse mechanism transport the substrates to the substrate mounting portion and to the second substrate transport mechanism. According to the above structure, since the substrate has two inversion mechanisms, the substrate can be doubled in each unit. This allows more substrates to be reversed per unit time, thus reducing processing time. Further, the substrate transfer mechanism and the second substrate transfer mechanism are disposed on the straight line to provide a polarizing film bonding apparatus having a structure with more excellent area efficiency. Moreover, the polarizing and closing apparatus of the present invention preferably has a transporting polarizing film 2〇1137464, a first film transporting mechanism and a second film transporting mechanism, and the first film transporting machine is provided for winding out the polarized light protected by the peeling film. a plurality of rolls of the film, a cut portion for cutting the polarizing film, a removal portion for removing the release film from the polarizing film, and a plurality of rolls for winding the removed release film a second portion of the second film transporting mechanism: a plurality of winding portions for winding up the polarizing film protected by the release film for cutting the polarizing film, and for cutting the polarizing film a removal portion for peeling inspection and a plurality of winding portions for winding the removed release film; the first substrate transfer mechanism and the second substrate transfer mechanism are provided in the first film transfer mechanism and the second a first bonding portion for bonding the polarizing film after removing the release film to the substrate is provided between the first film conveying mechanism and the first substrate conveying mechanism, and is used for the upper portion of the film conveying mechanism Bonding the polarizing film after removing the release film to the second of the substrate The bonding unit is provided between the second film transport mechanism and the second substrate transport mechanism. By this means, since the plurality of winding portions and the winding portion are provided, when the residual amount of the polarizing film material in the winding portion on one side is small, the raw material can be connected to the raw material provided in the other side winding portion. As a result, it is not necessary to stop the winding of the polarizing film, and the operation can be continued, so that the production efficiency can be improved. Moreover, the polarizing film laminating apparatus of the present invention preferably has a cleaning portion for cleaning the substrate before the polarizing film is attached to the lower surface of the substrate by the first bonding portion, and the first substrate transfer mechanism is The substrate is conveyed with the short side of the substrate in the transport direction. Thereby, the substrate can be cleaned by the cleaning portion in a state where the long side of the substrate is perpendicular to the substrate conveyance direction. That is, the substrate 8 201137464 > can be reduced in the distance in the transport direction, so that the processing time required for washing can be shortened. The result 'provides a polarizing film laminating device with more excellent production efficiency. Further, in the polarizing film coating apparatus of the present invention, the first film transporting mechanism and the second film transporting mechanism have a defect detecting portion that can detect the rollout from the first winding portion. The defect attached to the polarizing film is displayed; the bonding avoidance portion determines that the defect is displayed to stop the transfer of the substrate; and the recovery portion collects the polarizing film that is avoided and is not bonded to the substrate. According to the defect detecting portion, the bonding avoiding portion, and the collecting portion, it is possible to prevent the polarizing film having the defect from being bonded to the substrate, so that the yield can be improved. The liquid crystal display device manufacturing system of the present invention includes: the polarizing film bonding device described above; and a bonding deviation detecting device for inspecting a bonding deviation on the substrate after the polarizing film is bonded by the second bonding portion .

Further, it is preferable that the liquid crystal display device manufacturing system of the present invention has a selection transport device that judges whether or not a foreign matter is present by the inspection result of the automatic foreign matter detecting device for bonding, and according to the result of the determination, the polarizing film has been attached. The substrate is selected. As a result, when a foreign matter is mixed into the liquid crystal panel to which the polarizing film is bonded, it can be quickly selected as a defective product, and the processing time can be shortened. Moreover, it is preferable that the liquid crystal display device manufacturing system of the present invention has an automatic foreign matter detecting device for attaching a foreign matter on a substrate after the polarizing film is bonded by the second bonding portion, and has a selection and transporting device.

Further, since the operation of the reversing mechanism is a simple operation, the processing time is short. Therefore, a fitting with a short processing time can be achieved. Further, the first substrate transfer mechanism and the second substrate transfer mechanism are disposed in the same direction. In other words, it does not have a complicated structure such as an L-shape. Therefore, the polarizing film laminating apparatus of the present invention has an effect of being extremely simple to set up and excellent in area efficiency. [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to Figs. 1 to 8 but the present invention is not limited thereto. First, the structure of the liquid crystal display device manufacturing system of the present invention will be described as follows. The liquid crystal display device manufacturing system includes the polarizing film bonding device of the present invention. Fig. 1 is a cross-sectional view showing a manufacturing system of a liquid crystal display device. As shown in Fig. 1, the liquid crystal display device manufacturing system 100 has a two-layer structure ^1F (1st floor) and a film transport mechanism 50.

The function of the film transport mechanism 5 is to wind up the polarizing film (polarizing plate) and transport it to the rolling members 6, 6a and the nip rolls =, 16a, and take up the unnecessary release film. On the other hand, the function of the polarizing film bonding unit 60 is to bond the polarizing film rolled up by the film conveying mechanism 5 to the substrate (liquid crystal panel) 5. The film transport mechanism 50 has a first film transport mechanism 51 and a second membrane transport mechanism 52.

The thickness of the polarizing film is not particularly limited, but a polarizing film of 5 μm or more and 400 μm or less is preferably used. In the polarizing film web, the absorption axis direction is in the flow direction (MD direction). In the polarizing film, the adhesive layer is protected by a release film. A polyester film, a polyethylene terephthalate film or the like can be used as the release film (also referred to as a protective film or a separation membrane separator). The thickness of the release film is not particularly limited, but it is preferred to use a release film of 5 μm or more and ΙΟΟμηη or less. 12 201137464 The liquid crystal display device manufacturing system 100 has two winding portions and two winding portions corresponding to the winding portion, and when the amount of material remaining in the first winding portion 1 is small, it can be set in the second The roll of the take-up portion 1a is coupled to the roll of the first take-up portion 1. As a result, the operation can be continued without stopping the rolling out of the polarizing film. Therefore, the production efficiency can be improved by the present structure. Further, it is only necessary to have a plurality of the winding portions and the winding portions, respectively, and of course, it is also possible to have three or more winding portions and winding portions. The half cutter (cutting portion) 3 half-cuts the polarizing film (the film laminate composed of the polarizing film, the adhesive layer, and the release film) protected by the release film to change the polarizing film and The adhesive layer is cut. The half cutter 3 can use conventional components. Specifically, it can be, for example, a blade, a laser cutter, or the like. After the polarizing film and the adhesive layer are cut by the half cutter 3, the peeling film is removed from the polarizing film by the blade (removing portion) 4. An adhesive layer is applied between the polarizing film and the release film, and after the release film is removed, the adhesive layer remains on the polarizing film side. The pressure-sensitive adhesive layer is not particularly limited, and may be, for example, an adhesive layer such as a propylene-based, epoxy-based or polyurethane-based adhesive. The thickness of the adhesive layer is not particularly limited, but is usually 5 to 40 μm. On the other hand, the second film transport mechanism 52 has the same configuration as the first film transport mechanism 51, and has the first take-up portion 11, the second take-up portion 11a, the first take-up portion 12, and the second take-up. The portion 12a, the half cutter 13, the blade 14, and the defective film take-up rolls 17, 17a. Regarding the component named as the same name, it means that the function is the same as that of the first film transport mechanism 51. As a preferred embodiment, the liquid crystal display device manufacturing system 100 has a cleaning portion 71. The cleaning portion 7 is used to wash the substrate 5 before the polarizing film is bonded to the substrate 5 13 201137464 by the rolls 6, 6a. The washing portion η can be formed by the spray-like bristles # of the jet cleaning liquid. The cleaning unit 7i cleans the substrate 5 to be bonded, and bonds the substrate 5 with a small amount of foreign matter attached thereto. Next, the knife 4 will be described with reference to Fig. 2 . Fig. 2 is a cross-sectional view of the peripheral portion of the roll 6 of the device manufacturing system 100. The figure 2 shows the polarizing film of the following (4)) when the substrate 5 is transported from the left to the right. The polarizing film 5a has a peeling _ 5b and is cut by the half cutter 3 = 5a and the adhesive layer, but the peeling film 不会 is not cut, and the blade 4 is provided on the side of the peeling 5b. The blade 4 is a blade-like member for peeling off, and the peeling film 5b is peeled off along the blade 4 in association with the polarizing film 5a. After the force is low, the release film 5b is then taken up by the first take-up portion 2 of Fig. 1. In addition, the village replaces (4) and manufactures the structure of the membrane by (4). At this time, the same as the enemy Qiu Ganyu, the smuggling of the smuggling of the smuggling 1 by placing the adhesive roller at a position, can improve the take-up efficiency of the peeling film. /Secondly, (4) Polarizing film bonding device (9). The polarized light-dissipating device 6 transports the substrate 5, and bonds the polarizing film that has been transported by the transport mechanism 5 () to the substrate. Although not shown in the drawing, in the fine bonding apparatus 60, clean air is supplied to face the upper side of the substrate 5. That is, downflow rectification is performed. Thereby, the substrate 5 can be transferred and bonded in a stable state. <Polarizing 臈 bonding apparatus> The polarizing film bonding shovel 60 is provided in the upper part of the film conveying mechanism 50. 201137464 Thereby, space saving of the liquid crystal display device manufacturing system 100 can be achieved. Although not shown in the drawing, a substrate transfer mechanism is provided in the polarizing film bonding apparatus 60, which has a conveyor roller, and the substrate 5 is conveyed in the conveyance direction (hereinafter, in the 5th to 5th drawings). The first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 correspond to a substrate transfer mechanism. In the liquid crystal display device manufacturing system 100, the substrate 5 is transported from the left side, and then transported from the upper portion of the first film transport mechanism 51 to the upper portion of the second film transport mechanism 52 on the right side in the drawing. Each of the film transport mechanism 5A and the polarizing film bonding apparatus 60 has a rolling speed 6, 6a (first bonding portion) as a bonding portion, and rolls 16, 16a (second bonding portion). The rolls 6, 6a and 16, 16a are used to bond the polarizing film after the release film has been removed to the assembly under the substrate 5. Further, the film 5 is bonded to the rolls 6 and 6a in order to bond the polarizing film to the both sides of the substrate 5 from below, and then the substrate 5 is reversed by the reversing mechanism 65. The inversion mechanism 65 will be described later in detail. The polarizing film that is transported toward the rolls 6, 6a is bonded to the lower side of the substrate 5 via the adhesive layer. As the planners 6, 6a, a conventional structure such as a press roller "pressure roller" can be used. Further, the pressure and temperature at the time of bonding of the rolling members 6, 6a can be appropriately adjusted. The structure of the rolls 16, 16a is also the same. Further, although not shown in the drawings, in the preferred configuration of the liquid crystal display device manufacturing system, a defect mark (Mark) detecting portion is provided at a position between the first winding portion 1 and the half cutter, and is detectable. A structure of a polarizing film having defects. In addition, the defect mark is subjected to inspection when the polarizing film roll is produced, and the defect mark is given, or on the polarizing film, the defect mark is given to the mark, and the part is given to be close to the first-roll-out portion. n or the second volume: Part 2: The department is assigned to the department by the camera, image processing device and defect indication. First, 'Photographing the polarizing film with the camera: Shadow information processing' can be checked Is there a defect? The defect may be, for example, foreign matter such as dust, fisheye, or the like. ς In the case of a defect, a defect mark is formed on the polarizing film by the defect mark forming portion. The defect indication can be marked with ink or the like. Further, the bonding avoiding portion not shown in the figure recognizes the mark by the camera, and transmits the stop signal to the polarizing film bonding device 6 to stop the conveyance of the substrate 5. Then, the defective polarizing film is not attached by the rolls 6, 6a, but is taken up by the defective film winding drum (recycling unit) 7, 7a. Thereby, the substrate 5 can be prevented from being bonded to the polarizing film having defects. As long as the structure of the series is provided, since the defective polarizing film can be prevented from being bonded to the substrate 5, the yield can be improved, which is a preferred embodiment. A conventional inspection sensor can be used for the defect detecting portion and the bonding avoiding portion. As shown in Fig. 1, after the substrate 5 is reversed by the reversing mechanism 65, the substrate 5 is transferred to the rolls 16, 16a. Next, the polarizing film is bonded to the lower side of the substrate 5. As a result, the polarizing film can be bonded to both surfaces of the substrate 5, and two polarizing films having different absorption axes are bonded to each other on both surfaces of the substrate 5. Then, both sides of the substrate 5 are inspected as needed to check for a misalignment. Usually, the inspection is carried out using a 201137464 inspection unit having a camera. In the above-described liquid crystal display device manufacturing system, when the polarizing film is bonded to the substrate 5, the structure is bonded from the lower side of the substrate 5, so that the rectifying environment of the substrate 5 is not hindered. Therefore, it is possible to prevent foreign matter from entering the bonding surface of the substrate $, and it is possible to perform bonding more accurately. Figures 3a and 3b show the velocity vector of the gas flow in the post-production manufacturing system of the present invention. In Figs. 3a and 3b, the area a = the area where the winding portion is provided, the area B is mainly the area through which the polarizing film passes, and the area C is the area where the winding portion or the like is provided. Also, clean air is supplied from η 40 . In addition, in Fig. 3a, since the grating 41 which allows clean air to pass is provided, the crucible surface is moved in the straight direction via the grating 41. In Fig. 3b, since the grid tree 41 is not provided, the airflow is in contact. After the floor, it moves along the floor. Since the liquid crystal display panel manufacturing system shown in Figs. 3a and 3b is of the lower-mount type, it is different from the airflow from the HEPA filter 40 due to the polarizing film as shown in Figs. 9a and 9b. Therefore, the direction of the airflow vector is almost always toward the substrate, which is a better rectifying environment in which a clean room can be achieved. A grid 41 is provided in Fig. 3a, and is not provided in Fig. 3b, but both are also preferably in a preferred state. Further, in Figs. 3a and 3b and Figs. 9a and 9b, although the substrate transport mechanism is horizontal, it is not provided in a series of structures. Therefore, a structure in which a gas flow can pass between the substrate transfer mechanisms can be achieved. The substrate is held by the inversion mechanism described later, and then transferred to the structure between the substrate transfer mechanisms. Further, in the liquid crystal display device manufacturing system 100, first, the substrate 5 is transported with the long side facing the front of the 201138764 (the long side is perpendicular to the transport direction), and then the short side is forward (the short side is perpendicular to the transport direction). structure. <Reverse mechanism> The reversing mechanism 65 is a state in which the short side or the long side can be arranged along the substrate 5 in the transport direction to form a long side or a short side along the transport direction. 4a to 4c are perspective views of the process of inverting the substrate 5 by the reversing mechanism 65. Fig. 4a shows a state in which the substrate 5 conveyed by the first substrate transfer mechanism is adsorbed. Fig. 4b is a process of moving the substrate 5, and Fig. 4c is a state in which the substrate 5 is reversed by the second substrate inverting mechanism. Further, for convenience of illustration, the first substrate transfer mechanism and the second substrate transfer mechanism are omitted in Figs. 4a to 4c, and are left as to be described later in Figs. 5a to 5d. As shown in Fig. 4a, the reversing mechanism 65 has a suction portion 66, a substrate inverting portion 67, and a lifting portion 68. The absorbing portion 66 is a member for absorbing the surface of the substrate 5. The surface of the substrate 5 is held by the absorbing portion 66 at the absorbing portion 66. The absorbing portion 66 can use a conventional absorbing portion, and for example, an air suction absorbing portion can be used. The substrate inverting portion 67 is coupled to the absorbing portion 66 to connect the absorbing portion 66 and the lifting portion 68. The substrate inverting portion 67 reverses the assembly of the substrate 5 by rotating the reverse axis Μ as an axis. In Fig. 4a, the side of the elevating portion 68 of the substrate inverting portion 67 is formed to extend in the vertical direction with respect to the inversion axis 朝向 toward the substrate 5. Further, the side of the absorbing portion 66 of the substrate inverting portion 67 is formed by the 201137464 core in the substrate 5 passing through the first substrate transfer mechanism, and is bent by about 40° along a straight line parallel to the long side (transport direction) of the substrate 5. shape. The shape of the substrate inverting portion 67 shown in Fig. 4a is only an example, and is not limited to this shape. The other shape may be, for example, a shape curved from the side of the ascending portion 68 toward the side of the absorbing portion 66 instead of the curved shape as the substrate reversing portion 67. Further, a structure having a plurality of movable portions like a robot arm may be employed. The substrate inverting portion 67 has a structure in which a movable portion that can be rotated is provided at the elevating portion 68. The movable portion is disposed along the reverse axis ,, and the structure in which the substrate inverting portion 67 is rotated along the reverse axis 可 can be performed. • The inversion shaft system (1) is located on a plane including a line that is inclined by 45° with the center of the substrate 5 passing through the first substrate transfer mechanism and a line perpendicular to the conveyance direction of the substrate 5 as a reference. And it is perpendicular to the substrate 5 (refer to FIG. 5a); (2) and is located at a level horizontal to the substrate 5 (refer to FIG. 4a). The inversion axis Μ can also be located on the above plane, and the substrate 5 can be moved to the vertical direction. The substrate inverting portion 67 is configured to be rotatable along the reverse axis by the movable portion. However, the structure is not particularly limited as long as it can be rotated along the reverse axis. For example, the substrate inverting portion 67 has a rotating shaft structure, and the axis of the rotating shaft structure is rotated back along the inversion axis, and the entire substrate inverting portion 67 is rotated. The turning motion of the substrate inverting portion 67 is performed by, for example, a driving device such as a motor (not shown). The substrate inverting portion 67 is capable of inverting the substrate 5 by one rotation of the inversion axis Μ. The so-called reversal means that the substrate 5 is rotated to the opposite side, and the surface of the substrate 5 is turned to the back side in exchange for 201137464. The elevating portion 68 has an arm shape having a curved portion, and the substrate reversing portion 67 can be raised by reducing the angle of the arm. On the other hand, the substrate inverting portion 67 can also be lowered by increasing the angle of the arm. When the substrate 5 is not transferred, the absorbing portion 66 is placed on the upper side of the substrate 5 to avoid contact with the substrate 5. Then, when the substrate 5 is transported, the substrate inverting portion 67 is lowered by the elevating portion 68, and the absorbing portion 66 is also lowered, whereby the substrate 5 can be adsorbed by the absorbing portion 66. Further, after the substrate 5 is reversed, the suction of the absorbing portion 66 is released, and after the release, the substrate reversing portion 67 is moved by the elevating portion 68. The absorbing portion 66 is separated from the substrate 5. The operation of the inversion mechanism 65 will be described using Figs. 4a to 4c. First, in Fig. 4a, the case where the short edge of the substrate 5 is conveyed is shown. After the surface of the substrate 5 is adsorbed by the absorbing portion 66, the substrate inverting portion 67 is rotated along the inversion axis M. In Fig. 4a, the vicinity of the center of the substrate 5 is adsorbed by the absorbing portion %. However, the substrate 5 does not fall when it is fixed, and the adsorption position is not particularly limited. Further, the adsorption position is not limited to four positions, and may of course be appropriately increased or decreased. Then, from the state of Fig. 4a, the substrate inverting portion 67 is rotated along the inversion axis Μ toward the substrate surface side. Fig. 4b shows the substrate inverting portion 67 being rotated relative to the substrate 5 in the first substrate transfer mechanism (Fig. 4a). After the state. The state in which the substrate inverting portion 67 is rotated by the state of Fig. 4b is continued, and the substrate 5 is reversed as shown in Fig. 4c. As described above, by the one-turn operation of the reversing mechanism 65, the short side and the long side direction of the substrate 5 can be changed and inverted. That is, the reversal of the substrate 5 can be performed with a short processing time (Tact Time) without the need for a complicated turning operation of 201137464. As a result, the polarizing film bonding work including the substrate 5 having the reversal can be performed with a short processing time. Further, in the fourth to fourth embodiments, in order to move the substrate 5 in the transport direction, the substrate inverting portion 67 is placed on the transport direction side with respect to the substrate 5 of Fig. 4a. As a result, as shown in Fig. 4c, the second substrate transfer mechanism can be reversed while the substrate 5 is moved further in the transport direction. In this way, it is possible to carry out the two-sided bonding industry including the reverse operation with a shorter processing time. * Figures 5a through 5d correspond to top views of the substrate 5 of Figures 4a through 4c during the turning process. The first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 are shown in Figs. 5a to 5d. The first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 have transport rollers (not shown). The first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 transport the substrate 5 in the same direction. Therefore, the first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 have a linear structure along the transport direction. In other words, it does not have a complicated structure such as an L shape. Therefore, the polarizing film bonding apparatus 60 of the present invention is extremely simple in arrangement and is excellent in area efficiency. * As described with reference to Figs. 4a to 4c, first, as shown in Fig. 5a, the surface of the substrate 5 is held by the absorbing portion 66. Next, as shown in Fig. 5b, the substrate inverting portion 67 is rotated by 90° in the direction of the inversion axis 而 to bring the substrate 5 into a vertical state. Finally, as shown in Fig. 5c, the substrate inverting portion 67 is continuously rotated in the direction of the inversion axis 以 to invert the substrate 21 201137464 5 . When the substrate 5 is reversed, the substrate 5 is placed on a transport roller (not shown), and the substrate inverting portion 67 does not come into contact with the transport roller. Therefore, the 'reverse mechanism 65' is located on the lower side of the substrate 5. Then, the substrate 5 is transported by the second substrate transport mechanism 62 by releasing the adsorption of the absorbing portion 66 to release the substrate 5. Next, the reversing mechanism 65 returns to the position of Fig. 5a, and reverses the other substrates 5 that are sequentially transported in the same manner. The reversing mechanism 65 as described above, after the adsorption by the absorbing portion 66, reverses the substrate 5 by one operation of the substrate 5, and changes the long side and the short side with respect to the transport direction. Before the inversion operation, the polarizing film ‘ is bonded to the lower side of the substrate 5, and after the reversing operation is performed, the polarizing film can be bonded to the lower side of the inverted substrate 5 again. (1) The polarizing film can be bonded to the both surfaces of the substrate 5 from below as described above. (2) The reversing operation is a simple turning operation, and the single machining time is short. Therefore, it is possible to achieve a bonding industry that does not hinder the rectification environment and has a short processing time. Further, the reversing operation of the substrate inverting portion 67 is performed once, but the operation of the position of the front and rear lifting and lowering substrate 5 and/or the adjustment of the substrate inverting portion 67 is included in the reverse of the present invention. The operation of the turning mechanism 65 is in progress. In the fifth to fifth embodiments, the first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 are configured such that the substrates 5 are transported in the same direction and are adjacent to each other. As shown in FIG. 5e, the short side of the substrate 5 with respect to the transport direction is changed by the substrate inverting portion 67, and the second substrate transport mechanism 62 of the reversed substrate 5 is transported and the first side is 22 201137464. The conveying direction of the conveying mechanism 61 does not occur on a straight line, but an offset occurs. Further, the first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 do not have to be adjacent to each other, and a gap may be provided between the first substrate transfer mechanism 61 and the second substrate transfer mechanism 62. As shown in Figs. 4a to 4c, in order to move the substrate 5 in the transport direction, the substrate inverting portion 67 is provided on the transport direction side with respect to the substrate 5 before the inversion. However, when the arrangement of the reversing mechanism 65 or the like is limited, the reversing mechanism 65 may be provided as shown in Fig. 5d. At this time, although the substrate 5 cannot be moved in the conveying direction, it may correspond to the opposite The limitation of the configuration of the transfer mechanism 65 and the like. Fig. 6 is a plan view showing a variation of the embodiment in which the polarizing film is attached to the nest. The change in the modified embodiment is as follows: (1) having two reversing mechanisms 65'(2) having two substrate mounting portions 61a on both sides of the first substrate transfer mechanism 61. (3) First substrate transfer The mechanism 61 and the second substrate transfer mechanism 62 are disposed on a straight line. Further, similarly, the substrate $ can be transported in the same direction by the first substrate transport mechanism 61 and the second substrate transport mechanism 62. * The first substrate transfer mechanism 61 is adjacent to the second substrate transfer mechanism 62 side '= end portion, and has a base (four) portion 61a along the horizontal direction of the end portion with respect to the transport direction of the first substrate transfer mechanism 61 and Reverse mechanism 65. The structure of the inversion mechanism 65 is the same as that described with reference to & @ to 4c and 5a to 5d. Further, the end portion region 61b has a conveying means for conveying the substrate 5 toward the substrate placing portion. Specifically, it can be, for example, a roller. 23 201137464 The substrate mounting portion 61a is provided with the substrate 5 by the absorbing portion 66. According to this modified embodiment, the substrates 5 conveyed along the first substrate transfer mechanism 61 are alternately transferred to the two substrate mounting portions 61a. Since the two pairs of the substrate mounting portion 61a and the reversing mechanism 65 are provided, the substrate 5 conveyed to the substrate placing portion 61a is reversed by one operation of the reversing mechanism 65. In the modified embodiment, the two substrate mounting portions 61a are provided along the horizontal direction of the first substrate transfer mechanism 61, and the inverted substrate 5 is disposed along the transport direction of the first substrate transfer mechanism 61. . Therefore, the first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 can be arranged on a straight line. According to this modified embodiment, (1) since the two inversion mechanisms 65 are provided, the substrate 5 can be treated twice as much per unit time. Thereby, more substrates 5 can be reversed per unit time, and the processing time can be shortened. (2) Further, since the first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 are disposed on a straight line, it is possible to provide a polarizing film bonding apparatus having a structure with improved area efficiency. Especially in the clean room, the area efficiency is very high, and it is very suitable to use the polarizing film bonding device. <Other attached structure> Further, as a preferred embodiment, the liquid crystal display device manufacturing system 100 includes a control unit 70, a cleaning unit 71, a bonding deviation detecting device 72, a bonded foreign matter automatic detecting device 73, and a selection transfer. Device 74. The bonding deviation detecting device 72, the bonded foreign matter automatic detecting device 73, and the selective conveying device 74 perform processing such as inspection on the bonded substrate 5 (liquid crystal display device). Fig. 7 is a block diagram showing the relationship between each group of 24 201137464 pieces of the liquid crystal display device manufacturing system, and Fig. 8 is a flow chart showing the operation of the liquid crystal display device manufacturing system. Hereinafter, the components of the liquid crystal display device will be described, and the operation thereof will be described. The control unit 70 is connected to the cleaning unit 71, the bonding deviation detecting device 72, the bonded foreign matter automatic detecting device 73, and the selective transport device 74, and controls the control signals to be transmitted to the components. The control unit 7 is mainly composed of a CPU (Central Processing Unit), and can have a memory as needed. In the case where the liquid crystal display device manufacturing system 100 has the cleaning portion 71, in order to shorten the processing time of the cleaning portion 71, it is preferable that the substrate 5 in the first beauty sheet conveying mechanism 61 has the long side forward. The method is transferred to the washing unit 71. In general, the above structure is very effective from the viewpoint of shortening the processing time because the washing at the cleaning portion 71 takes a long time. Next, S2 of Fig. 8 performs a bonding step of bonding the polarizing film to both sides of the substrate (including the reverse operation of the substrate 5), and the above steps are as described with reference to Figs. 1 to 6 . The bonding deviation detecting device 72 is for checking whether or not the bonding deviation of the polarizing film exists in the bonded substrate 5. The bonding deviation detecting device is composed of (4) a video camera and an image processing device, and the polarizing film of the substrate 5 is bonded by rollers 16, 16a, and a camera is disposed at a bonding position of the polarizing film. By photographing the substrate 5 by the camera, it is possible to check whether or not the substrate 5 is present by the image processing by the stitching (the bonding deviation checking step, S3 in Fig. 8). Further, the adhesion difference detecting means 72 can detect the vibration using the pasting deviation known in the past. 25 201137464 The automatic foreign matter detecting device 73 is used to check whether or not foreign matter is present in the bonded substrate 5. Similarly to the bonding deviation detecting device 72, the bonded foreign matter automatic detecting device 73 is composed of a camera and an image processing device, and the second substrate transfer mechanism bonds the polarizing film to the substrate 5 by the rolls 16, 16a, and second. The camera is provided at the substrate transfer mechanism (polarizing film bonding device 60). By photographing the substrate 5 by the camera, it is possible to check whether or not the bonded material is present on the substrate 5 by processing the image data which has been photographed (the foreign matter inspection step is bonded, S4). The foreign matter may be, for example, a foreign matter such as dust or fish eyes. Further, the foreign matter detecting and detecting device 73 can be attached to the conventional foreign matter detecting device. The order of S3 and S4 can be reversed or simultaneously. Also, any of the steps can be omitted. The picking and transporting device 74 determines whether or not there is a bonding deviation or a foreign matter based on the inspection results of the bonding deviation detecting means 72 and the bonded foreign matter automatic detecting means 73. The selection conveyance device 74 may be used to select the substrate 5 to be bonded as a good or defective product as long as it can receive the inspection result of the inspection result from the bonding deviation detecting device 72 and the bonded foreign matter automatic detecting device 73. Therefore, the conventionally selected transport system can be used. In the liquid crystal display device manufacturing system, as a preferred embodiment, it is possible to detect the difference in the bonding deviation and the foreign matter, and determine that the deviation or the foreign matter is detected (YES). The bonded substrate 5 is selected as a defective product (S7). On the other hand, if it is determined that the bonding deviation and the foreign matter are not detected (NO), the bonded substrate 5 is selected as a good product (S6). 26 201137464 Using the liquid crystal display device manufacturing system with the selection transfer device 74 The selection of good or defective products can be quickly performed, and the processing time can be shortened. When only the bonding deviation detecting device 72 or the foreign matter automatic detecting device 73 is attached, the selective conveying device 74 may be configured to judge only one of the bonding deviation and the foreign matter. In addition, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included. It is included in the technical scope of the present invention. * The polarizing film laminating device of the present invention can be applied to the technical field of bonding a polarizing film to a substrate.
