Description

玻璃基板保護墊及玻璃基板封裝容器 【0001】
本專利申請案主張於2013年4月15日提出之韓國專利申請案號第10-2013-0040952號之優先權，其全部揭露併入本文作為參考。
【0002】
本發明是有關於一種玻璃基板保護墊及玻璃基板封裝容器，特別是有關於一種可大幅降低玻璃基板損壞率之玻璃基板保護墊及玻璃基板封裝容器。
 【0003】
封裝容器是用以作為一裝置以封裝用以作為顯示面板等之複數個玻璃基板。舉例而言，於傳送玻璃基板至顯示面板製造業者之前，玻璃基板製造業者會封裝已製造好的複數個玻璃基板於封裝容器中。於一狀態中，玻璃基板封裝容器承載例如180至240個玻璃基板於其上，其中此狀態為於此些玻璃基板中間各別插入紙張及/或膜。於此，為了保護裝載於封裝容器上之玻璃基板，玻璃基板保護墊會緊密接觸於堆疊之180至240個玻璃基板之前表面。
【0004】
然而，由於表面張力/印痕，相關領域中之玻璃基板保護墊具有高損壞率之問題。再者，隨著玻璃基板之尺寸增加(例如本發明之玻璃基板封裝容器係用以封裝長度或寬度超過2公尺之玻璃基板)，玻璃基板保護墊之重量亦隨之增加。封裝或拆裝作業之工作性不佳，這是有問題的。此外，如此劣化之工作性導致了工人於封裝或拆裝中之誤差，因而造成了玻璃基板之底部之損傷。另外，因為玻璃基板保護墊並未具有充足之耐久性，因此當長時間使用時，其邊緣會特別地破損而導致玻璃基板之損傷。更甚者，於相關領域中之玻璃基板保護墊中，面對接觸玻璃基板保護墊之膜、紙張或玻璃基板可能會因為表面壓力而沿著玻璃基板保護墊移動，因而會劣化工作性而產生問題。
【0005】
本發明先前技術章節中所揭露之資訊僅係用以更加了解本發明之背景，不應作為形成本發明所屬技術領域中具有通常知識者已充分理解之先前技術之任何知識或建議訊息之形式。
 【0006】
本發明的各種態樣係提供一種可大幅降低其損壞率之玻璃基板保護墊。亦提供一種可提升封裝或拆裝玻璃基板作業之工作性之玻璃基板封裝容器。也提供一種可大幅降低玻璃基板損壞率之玻璃基板保護墊。
【0007】
於本發明之一態樣中，提供一種保護玻璃基板及緊密接觸玻璃基板之玻璃基板保護墊。此玻璃基板保護墊具有複數層， 緊密接觸玻璃基板之複數層中之背層含有發泡聚合物。
【0008】
於本發明之另一態樣中，提供一種用以封裝裝載於其中之複數個玻璃基板之玻璃基板封裝容器，其中上述之玻璃基板保護墊係緊密接觸複數個玻璃基板之前面。
【0009】
根據本發明之實施例，因為使用由發泡聚合物所形成之背層，其可大幅降低由保護膜所造成之玻璃基板損壞率。
【0010】
此外，因為包含於保護膜中之高強度插入物避免保護膜變形，其可防止保護膜損傷。於是，其可大幅降低玻璃基板中由保護墊之其他原因所造成之損傷。
【0011】
再者，因為降低了保護墊之重量，因此可提升工作性。於是，其可大幅降低於工作中之玻璃基板損傷率。
【0012】
此外，因為設置彈性件於保護墊之角落，其可防止保護墊之角落損傷。於是，其可大幅降低由保護膜所造成之玻璃基板損傷率。
【0013】
更甚者，因為於背表面上形成凹凸部分，其可防止或降低膜、紙張或玻璃基板沿著保護膜之移動。
【0014】
本發明之方法及設備於所附圖示中及後續實施方式中所出現或進一步詳述之其他特徵或優點係包含於此，且共同用以解釋本發明之主要原理。

現將參照所附圖式及下述之內容，詳述本發明的各種實施例，使得本發明相關技術領域中具有通常知識者可輕易地實現本發明之內容。
【0021】
於本文件中，將參照所附圖式，其中說明書中不同圖式之相同的參考數字及符號係代表相同或相似之元件。於本發明之後續描述中，當詳述於此所包含之已知功用及元件會造成本發明之技術特徵不明確時，則其將會被省略。
【0022】
第1圖係為顯示根據本發明之第一實施例之玻璃基板封裝容器之透視圖。如第1圖所示，第1圖所示之玻璃基板封裝容器100係用以封裝複數個玻璃基板10，其中此些玻璃基板10係用以製造顯示面板，例如液晶顯示器(LCD)、電漿顯示面板(PDP)、有機發光二極體(OLED)或觸控螢幕面板(TSP)。
【0023】
第1圖所示之玻璃基板封裝容器100包括裝載部件110及覆蓋部件120。
【0024】
裝載部件110係為形成封裝容器100之基本架構之元件，且其支撐玻璃基板10之底部及背表面，使得玻璃基板10裝載於其中。(於本說明書中，前後方向、上下方向及左右方向係為相對之方向，其設置係為了方便解釋)。
【0025】
覆蓋部件120係為覆蓋裝載於裝載部件110上之玻璃基板10之元件，藉此隔絕玻璃基板及外部。覆蓋部件120係設置於裝載部件110上，使得覆蓋部件120可沿著裝載部件110之導軌111滑動。覆蓋部件120包括前外殼121。
【0026】
複數個玻璃基板10係封裝於玻璃基板封裝容器100中，且裝載於其中。於此，玻璃基板保護墊20係緊密接觸堆疊之玻璃基板10之前表面，因而保護此些玻璃基板10。
【0027】
第2圖係為顯示根據本發明之第二實施例之玻璃基板保護墊20之透視圖，第3圖係為第2圖所示之玻璃基板保護墊20之爆炸透視圖，第4圖係為第2圖所示之玻璃基板保護墊之角落之放大側視圖，以及第5圖係為第2圖所示之玻璃基板保護墊之角落之放大透視圖。
【0028】
第2圖所示之玻璃基板保護墊20之背表面係緊密接觸堆疊之玻璃基板。玻璃基板保護墊20係用以保護此堆疊之玻璃基板。玻璃基板保護墊20係配置為複數層。根據第2圖所示之實施例，玻璃基板保護墊20包括前層26、插入物25、內層23、彈性件24、插入物22及背層21。然而，其顯而易見的是，本發明之玻璃基板保護墊20之配置並不局限於此，而係定義於後附之申請專利範圍中。第2圖所示之玻璃基板保護墊20於前後方向、左右方向及上下方向均為對稱的。因此可藉由翻轉玻璃基板保護墊20，而不須區別其前後、左右或上下方向而使用此玻璃基板保護墊20。然而於一些實施例中，玻璃基板保護墊20的配置亦可能沒有對稱結構。而於此實施例中，其於前後、左右或上下方向上將會有所區別。前層26、插入物25、內層23、彈性件24、插入物22及背層21係依序地從前端開始排列。
【0029】
背層21係為緊密接觸玻璃基板之層狀。背層21含有 發泡聚合物。其較佳的是，背層21係由選自於乙烯乙酸乙烯酯(ethylene vinyl acetate, EVA)、發泡聚丙烯(expanded polypropylene, EPP)及發脹聚乙烯(expanded polyethylene, EPE)之至少一材料製造而成，但並不局限於此。背層21之背表面，亦即緊密接觸玻璃基板之表面，可具有凹凸部分。此凹凸部分可具有多種圖樣。舉例來說，此凹凸部分可具有條紋圖樣或點狀圖樣。
【0030】
每個插入物22及25相較於前層26、彈性件24、內層23及背層21，具有較大之強度。因此插入物22及25避免玻璃基板保護墊20彎曲。插入物22及25可實施為一輕且高強度之材料，此輕且高強度之材料可為多種材料，僅需其可維持強度，例如鋁薄板、塑料薄板。插入物22及25具有框架結構(骨架結構)。舉例而言，除了第2圖所示之梯形結構外，多種結構亦為有可能的，例如二條垂直桿相交於二條水平桿之結構。因為插入物具有框架結構，因此可減少其重量。其較佳的是，插入物22及25於上下方向及左右方向上係為對稱的。插入物22及25之上端及下端可形成為與玻璃基板保護墊20之上邊緣與下邊緣分隔開(如第4圖所示)。參照第3圖，插入物22及25之上端及下端可形成為與前層26、內層23及背層21之上邊緣與下邊緣分隔開。因此，插入物22及25之高度，亦即上端與下端之間之長度，可小於前層26、內層23及背層21之高度，亦即上端與下端之間之長度。根據第二實施例，其描述使用二個插入物22及25，其中一插入物25係插置於前層26及內層23之間，而另一插入物22係插置於內層23與背層21之間。然而，本發明並不局限於此。
【0031】
其較佳的是，內層23由乙烯乙酸乙烯酯製造而成。此外，物理性/化學性發泡之多種材料亦可用以作為內層。內層23於角落中具有穿孔23a。
【0032】
彈性件24係設置於內層23之穿孔23a中。彈性件23係由彈力佳於前層26、插入物25、內層23、插入物22及背層21之材料所製造而成，亦即其具有較低之彈性係數。彈性件24可例如由橡膠材料所實現。
【0033】
前層26含有發泡聚合物。其較佳的是，前層26 可由選自於乙烯乙酸乙烯酯(EVA)、發泡聚丙烯(EPP)及發脹聚乙烯(EPE)之至少一材料製造而成，但並不局限於此。前層26 可具有凹凸部分，此凹凸部分可具有多種圖樣。舉例來說，此凹凸部分可具有條紋圖樣或點狀圖樣。
【0034】
表1表示第2圖所示之玻璃基板保護墊20之減少厚度及重量之功效。
表1
【0035】
根據實施例，由於降低玻璃基板保護墊20之重量，所以提高了工作性，且因此其可降低由工人之失誤而產生之玻璃基板損壞率。
【0036】
表2表示藉由測試表1之實施例及比較例之保護墊所得之結果。測試係藉由設置盡可能不佳之測試條件而執行。再現評價係為每一項目於相同方法中執行50次。
表2
【0037】
比較例之玻璃基板保護墊於玻璃基板之邊緣只受到一次撞擊時就會損傷。相對地，實施例之玻璃基板保護墊20於受到三次撞擊後仍不會損傷。
【0038】
本發明之具體例示性實施例之先前描述已參照某些實施例及圖式而呈現。其不應意圖導向或限制本發明於此所揭露之具體形式，且顯而易見的是，本發明所屬技術領域中具有通常知識者依據上述之教示而進行任何修改或變化係為可能的。
【0039】
因此，本發明之範疇並不意在侷限於前述之實施例，而是由後附之申請專利範圍及其等效修改所定義。
