Description
本發明，係有關於玻璃板之端部加工裝置及端部加工方法。 The present invention relates to an end processing device and an end processing method for a glass sheet.
近年來，從省空間化的觀點來看，代替於先前技術中所普及之CRT型顯示器，液晶顯示器、電漿顯示器、有機EL顯示器、場發射顯示器等之平面面板顯示器係日益普及。而，對於此些之平面面板顯示器，係要求有更進一步之薄型化。 In recent years, from the viewpoint of space saving, flat panel displays such as liquid crystal displays, plasma displays, organic EL displays, field emission displays, and the like have become increasingly popular instead of the CRT type displays popular in the prior art. However, for such flat panel displays, further thinning is required.
特別是，在有機EL顯示器或有機EL照明中，係可利用其之厚度尺寸為非常小(薄)的特點，而使其具備可作折疊、捲起之類的功能。藉由此，不僅是在攜帶搬送上係變得容易，亦由於除了先前技術的平面狀態以外亦成為能夠進行在曲面狀態下之使用，因此係期待能夠對於各種用途作活用。故而，對於被使用在此些之可變形的電子裝置中之玻璃基板或覆蓋玻璃，係要求有更進一步之可撓性的提升。 In particular, in organic EL displays or organic EL illuminations, the thickness of the organic EL display or the organic EL illumination can be made very small (thin), and it can be folded or rolled up. As a result, it is easy to carry and transport, and it is also possible to use it in a curved state in addition to the planar state of the prior art. Therefore, it is expected to be useful for various purposes. Therefore, for a glass substrate or a cover glass used in such a deformable electronic device, a further improvement in flexibility is required.
為了將上述玻璃板之可撓性提高，將玻璃板 薄化一事係為有效。於此，例如在專利文獻1中，係提案有厚度尺寸300μm以下之玻璃板(亦有將此種尺寸大小的玻璃板稱作玻璃薄膜的情況)，藉由此，係成為能夠對於玻璃板而賦予可在曲面狀態下使用的程度之可撓性。 In order to improve the flexibility of the above glass plate, the glass plate is Thinning is effective. Here, for example, in Patent Document 1, a glass plate having a thickness of 300 μm or less is proposed (in the case where a glass plate having such a size is also referred to as a glass film), whereby it is possible to form a glass plate. Gives flexibility to the extent that it can be used in a curved state.
另一方面，在被使用於平面面板顯示器或太陽電池等之電子裝置中的玻璃板處，係被施加有二次加工或洗淨等之各種的與電子裝置之製造相關連之處理。然而，若是將被使用在此些之電子裝置中的玻璃板薄化，則就算是僅有些許的應力變化，也會有導致破損的情況，在進行與電子裝置之製造相關連之處理時，係有著處理會變得非常困難之問題。進而，厚度尺寸300μm以下、特別是200μm以下之玻璃板(玻璃薄膜)，由於係富有可撓性，因此，在施加各種之與製造相關連之處理時，也會發生難以進行定位的問題。 On the other hand, in a glass plate used in an electronic device such as a flat panel display or a solar cell, various processes related to the manufacture of an electronic device such as secondary processing or cleaning are applied. However, if the glass plate to be used in such an electronic device is thinned, even if there is only a slight stress change, damage may occur, and when processing related to the manufacture of the electronic device is performed, It is a problem that has become very difficult to handle. Further, since the glass plate (glass film) having a thickness of 300 μm or less, particularly 200 μm or less, is flexible, it is difficult to perform positioning when various processes related to manufacturing are applied.
關於上述問題，例如在專利文獻2中，係提案有一種方法，其係藉由一對之無端部皮帶來一面從表背面兩側挾持玻璃板一面朝向特定之方向進行搬送，並藉由被配設在側方之砥石，來對於端部進行研削。 In the above-mentioned problem, for example, in Patent Document 2, there is proposed a method in which a pair of endless leather belts are conveyed in a specific direction while holding a glass plate from both sides of the front and back sides, and are arranged by Set the side of the meteorite to grind the end.
另一方面，在此種玻璃板之表面上，係會有因應於其之用途而安裝有其他之要素或者是維持原本之狀態地來使用的情形，因此係會有被要求非常高之面精確度的情況。故而，係希望能夠盡可能地在至少於表、背面之其中一面上並不使任何之構件作抵接地來進行研削等之加工。 On the other hand, on the surface of such a glass plate, there are cases in which other elements are attached depending on the use thereof, or the original state is used, and therefore, the surface is required to be extremely high. Degree of situation. Therefore, it is desirable to perform processing such as grinding as much as possible on at least one of the front and back sides without causing any member to be grounded.
於此，例如係可考慮有在僅將玻璃板之表、背面其中一面(通常僅將下側之面)藉由定盤等來作支持的狀態下來施加研削加工之手法，但是，於此情況，係可能會發生有當對於先前技術之厚度尺寸的玻璃板進行加工時所不會設想到的問題。 Here, for example, it is conceivable to apply a grinding process in a state in which only one surface of the glass plate and the back surface (usually only the lower surface) are supported by a fixing plate or the like. However, in this case, There may be problems that would not have been envisaged when processing glass sheets of the prior art thickness dimensions.
亦即是，在此種加工(研削加工)中，通常，係使用具備有準據於加工型態之形狀的砥面之砥石，又，在由此砥石所進行之研削加工時，因應於玻璃板之材質或尺寸、研削型態等，係會將高壓之研削液(水等)主要噴吹至砥石和玻璃板之端部間的抵接部處。此時，雖然玻璃板之背面(下側之面)係被定盤等所支持，但是，起因於上述之理由，玻璃板之表面(上側之面)係以作了露出的狀態下而被進行研削加工。 In other words, in such a processing (grinding process), a vermiculite having a kneading surface having a shape which is in accordance with a processing type is usually used, and in the case of grinding by the vermiculite, the glass is required. The material or size of the plate, the grinding type, etc., are mainly sprayed on the high-pressure grinding fluid (water, etc.) to the abutment between the end of the vermiculite and the glass plate. In this case, although the back surface (lower side surface) of the glass plate is supported by the fixing plate or the like, the surface (upper side surface) of the glass plate is exposed in the exposed state due to the above reasons. Grinding processing.
因此，例如在專利文獻3中，係提案有一種研削加工裝置，其係設置有覆蓋砥石之蓋部，並且在此蓋部處形成開口部，而構成為能夠經由此開口部來使應進行研削之玻璃板的端部與砥石相抵接。藉由此，而成為能夠藉由蓋部來盡可能地對於被供給至砥石和玻璃板之端部間的抵接部處之研削液飛散至玻璃板之表面中央側處並附著於該表面上的事態作防止。 For this reason, for example, Patent Document 3 proposes a grinding processing apparatus which is provided with a cover portion covering the vermiculite, and an opening portion is formed in the cover portion, and is configured to be capable of being ground through the opening portion. The end of the glass plate abuts the vermiculite. By this, it is possible to scatter the grinding fluid which is supplied to the abutting portion between the end portions of the vermiculite and the glass plate as much as possible by the lid portion to the center side of the surface of the glass sheet and adhere thereto. The situation is prevented.

然而，玻璃板，由於係會隨著其之厚度尺寸的變小而變得容易起因於外部性之負載而產生變形，因此，起因於與砥石作抵接時之負載而導致在下方產生如同撓曲一般之變形的可能性係會提高。若是在如此這般地產生了變形的狀態下施加研削加工，則係無法避免對於面取數等之研削精確度的不良影響。又，若是厚度尺寸變得越小，則由於相對於外部性負載之強度也會變得越小，因此係會有發生起因於與砥石間之抵接所導致的玻璃板的破損(碎裂)之虞。 However, since the glass plate is deformed by the load of the external force as the thickness of the glass plate becomes smaller, it is caused by the load at the time of contact with the vermiculite. The possibility of a general deformation is improved. If the grinding process is applied in a state in which the deformation is caused in such a manner, the adverse effect on the grinding accuracy such as the surface number can not be avoided. In addition, if the thickness is smaller, the strength with respect to the external load is also reduced, so that the glass plate is broken (fragmented) due to the contact with the vermiculite. After that.
又，當藉由定盤等來支持玻璃板的情況時，係有必要在使應進行加工之玻璃板的端部從定盤等而超出的狀態下來進行加工。然而，若是成為在並不將玻璃板之一部分作支持的狀態下來施加加工，則會有玻璃板之端部僅起因於其自身之重量便產生撓曲變形之虞。又，研削液，由於通常係以高壓狀態而被供給(噴吹)，因此，若是並未被作任何支持之狀態下的玻璃板之端部承受研削液之供給，則會有導致該端部晃動(震動)之虞。上述之現象，係會隨著玻璃板之厚度尺寸變小而顯著地出現。 In addition, when the glass plate is supported by a fixed plate or the like, it is necessary to process the end portion of the glass plate to be processed from the fixed plate or the like. However, if the processing is performed in a state where one of the glass sheets is not supported, the end portion of the glass sheet may be deformed by the weight of the glass sheet only due to its own weight. Further, since the grinding fluid is normally supplied (injected) in a high pressure state, if the end portion of the glass sheet is not subjected to any support, the end of the glass plate is subjected to the supply of the grinding fluid, which may result in the end portion. Shake (shake). The above phenomenon occurs remarkably as the thickness of the glass sheet becomes smaller.
又，若是起因於上述之理由而導致玻璃板之端部產生變形或震動，則可能會發生蓋部之開口部和玻璃板之間的間隙變廣之事態。通常，此間隙，係因應於所使用之研削液的供給條件(水量或水壓等)和玻璃板之厚度尺寸等而被設定為適當之大小，但是，若是厚度尺寸變小，則除了相應於厚度尺寸之縮小所導致的間隙之增大以外，起因於上述之成為容易發生變形或震動的因素，也會導致間隙產生大幅變動(增大)之可能性的提高。如此一來，由於研削液飛散至玻璃板之表面中央側處並附著的可能性係提高，因此係會有對於表面精確度或清淨度等之製品品質造成不良影響之虞。為了對起因於變形等所導致的間隙之增加作對應，雖然可以預先將玻璃板和開口部之間的間隙設定為較小，但是，如此一來，則會另外產生起因於玻璃板之撓曲或晃動而導致玻璃板與開口部之間相互干涉的問題。 Further, if the end portion of the glass sheet is deformed or vibrated due to the above reasons, the gap between the opening portion of the lid portion and the glass sheet may become wide. Usually, the gap is set to an appropriate size depending on the supply conditions (water amount, water pressure, etc.) of the grinding fluid to be used, the thickness of the glass plate, etc., but if the thickness is small, the corresponding In addition to the increase in the gap due to the reduction in the thickness dimension, the above-described factors which tend to cause deformation or vibration are also likely to cause a large increase (increased) in the gap. As a result, since the grinding fluid is scattered to the center side of the surface of the glass sheet and the possibility of adhesion is increased, there is a possibility that the quality of the product such as surface accuracy or cleanliness is adversely affected. In order to correspond to an increase in the gap caused by deformation or the like, although the gap between the glass plate and the opening portion can be set to be small in advance, in this case, the deflection due to the glass plate is additionally generated. Or shaking causes a problem that the glass plate and the opening portion interfere with each other.
有鑑於以上之事態，在本說明書中，係以下述內容作為應藉由本發明所解決的技術性課題：亦即是，就算是對於相較於先前技術而厚度尺寸為更小的玻璃板，也能夠盡可能地防止玻璃板之變形以及對於玻璃板表面之液體的附著，而以高精確度來對於玻璃板之端部施加加工。 In view of the above, in the present specification, the following is a technical problem to be solved by the present invention: that is, even for a glass plate having a smaller thickness than the prior art, It is possible to prevent deformation of the glass sheet and adhesion to the liquid on the surface of the glass sheet as much as possible, and to apply processing to the end portions of the glass sheet with high precision.
前述課題之解決，係藉由本發明之玻璃板之 端部加工裝置而達成。亦即是，此端部加工裝置，係具備有支持玻璃板之支持台；和用以對於被支持於支持台之狀態的玻璃板之端部施加特定之加工之加工部；和覆蓋加工部，並且設置有用以使玻璃板之端部和加工部能夠抵接的開口部之蓋部，該玻璃板之端部加工裝置，其特徵為：支持台，係具備有支持玻璃板之中央側區域的第1支持部、和支持玻璃板之端部側區域之第2支持部，第2支持部之厚度尺寸係被設定為較第1支持部之厚度尺寸更小並且能夠在支持玻璃板之端部側區域的狀態下而通過蓋部的開口部之程度的大小。另外，於此之所謂中央側區域和端部側區域，係分別為代表在對於玻璃板作平面觀察的狀態下，以中心位置和端部位置之間之中間位置作為邊界，而較中間位置更靠中心側之區域和更靠端部側之區域。 The solution to the above problem is by the glass plate of the present invention. The end processing device is achieved. That is, the end processing device is provided with a support table having a supporting glass plate; and a processing portion for applying a specific processing to the end portion of the glass plate supported by the support table; and a covering processing portion, Further, a cover portion for opening an opening portion for contacting the end portion of the glass sheet and the processed portion is provided, and the end portion processing device for the glass sheet is characterized in that the support table is provided with a central side region of the support glass plate. The first support portion and the second support portion supporting the end portion side region of the glass plate, the thickness of the second support portion is set to be smaller than the thickness of the first support portion and can be at the end of the support glass plate The size of the opening portion of the lid portion in the state of the side region. In addition, the so-called central side region and the end side region are respectively represented as a boundary between the center position and the end position in a state in which the glass plate is viewed in a plane, and the intermediate position is more than the intermediate position. The area on the center side and the area on the side.
如此這般，在本發明中，由於係構成為在支持台處，而設置有支持玻璃板之中央側區域的第1支持部、和支持玻璃板之端部側區域的第2支持部，因此，就算是當玻璃板之厚度尺寸為小的情況時，亦能夠確實地支持玻璃板之端部側區域。又，於此情況，由於係將第2支持部之厚度尺寸設定為較第1支持部之厚度尺寸更小並且能夠在支持玻璃板之端部側區域的狀態下而使第2支持部通過蓋部的開口部之程度的大小，因此係能夠在使玻璃板之端部側區域被支持於第2支持部處的狀態下，而謀求該玻璃板之端部和被蓋部所覆蓋的加工部之間的抵接。藉由此，由於係能夠將被導入至蓋部內的玻璃板之包含有接近 於端部之區域的端部側區域之大部分，從加工開始前起便作支持，因此係能夠對於在與加工部相抵接時之玻璃板的變形作抑制，並且係能夠對起因於研削液之吹附等所導致的玻璃板之震動作抑制，而成為能夠進行高精確度之加工。又，藉由對於變形或震動作抑制，係能夠避免蓋部之開口部和玻璃板之間的間隙發生大幅度變動之事態。故而，係將上述間隙維持於特定之大小，而成為能夠盡可能地防止研削液等之液體飛散至玻璃板之表面中央側處並附著的事態。 As described above, in the present invention, since the first support portion for supporting the center side region of the glass sheet and the second support portion for supporting the end portion side region of the glass sheet are provided at the support stand, the second support portion for supporting the end side region of the glass sheet is provided. Even when the thickness of the glass plate is small, the end side region of the glass plate can be surely supported. In this case, the thickness of the second support portion is set to be smaller than the thickness of the first support portion, and the second support portion can be passed through the cover while the end portion side region of the glass plate is supported. In the state in which the end portion of the glass sheet is supported by the second support portion, the end portion of the glass sheet and the processed portion covered by the lid portion can be obtained in a state where the end portion of the glass sheet is supported by the second support portion. The abutment between. Thereby, the inclusion of the glass plate introduced into the lid portion is close to Most of the end side region of the end portion is supported from the start of the processing, so that the deformation of the glass sheet at the time of abutment with the processed portion can be suppressed, and the grinding fluid can be caused by the grinding fluid The shock suppression of the glass sheet caused by the blowing, etc., enables processing with high precision. Further, by suppressing the deformation or the vibration, it is possible to avoid a situation in which the gap between the opening portion of the lid portion and the glass sheet greatly changes. Therefore, the above-mentioned gap is maintained at a specific size, and it is possible to prevent the liquid such as the grinding liquid from scattering as much as possible to the center side of the surface of the glass sheet and to adhere thereto.
又，本發明之玻璃板之端部加工裝置，係亦可構成為：第2支持部，係為與第1支持部相互獨立地被形成者。又，於此情況，第2支持部，係亦可構成為相對於第1支持部而可作裝卸。 Moreover, the end portion processing device for a glass sheet according to the present invention may be configured such that the second support portion is formed independently of the first support portion. Further, in this case, the second support portion may be configured to be detachable from the first support portion.
如此這般，藉由將第2支持部與第1支持部相互獨立地而形成之，係能夠將要求用來支持玻璃板之中央側區域的第1支持部、和要求用來支持玻璃板之端部側區域的第2支持部，設為相異之規格。藉由此，係能夠防止各個的支持部成為過高之規格，並成為能夠在將各支持部之製作成本抑制為低的同時亦以高精確度來進行最後加工。又，玻璃板之端部側區域，通常，為了順暢且確實地進行由加工部所致之加工，係以使其之端部從第2支持部而突出有特定之尺寸的狀態來被第2支持部所支持。於此情況，在對於玻璃板之端部的從第2支持部所突出之突出尺寸和該玻璃板之厚度尺寸之間的關係作了調查後，係得 知了：依存於玻璃板之厚度尺寸，特別是起因於厚度尺寸從先前技術之尺寸而改變為最近之薄化尺寸(所謂的薄膜尺寸)，突出尺寸之適當的大小(範圍)係產生有大幅度的變化。故而，藉由將第2支持部構成為可相對於第1支持部而作裝卸，就算是在將厚度尺寸為相異之複數種類之玻璃板在同一之加工線上進行加工的情況時，也僅需要對於第2支持部作交換，便能夠作出適當的玻璃板之支持狀態。藉由此，係成為能夠對於厚度尺寸為相異之玻璃板的各者而分別施加高精確度之加工。 In this manner, by forming the second support portion and the first support portion independently of each other, it is possible to provide a first support portion for supporting the center side region of the glass sheet and to support the glass sheet. The second support portion in the end side region is set to a different specification. As a result, it is possible to prevent each of the support portions from being oversized, and it is possible to perform final processing with high accuracy while suppressing the manufacturing cost of each support portion. In addition, in the end portion side region of the glass sheet, in order to smoothly and surely perform the processing by the processing portion, the end portion is protruded from the second support portion by a specific size. Supported by the support department. In this case, after investigating the relationship between the protruding dimension of the end portion of the glass sheet protruding from the second support portion and the thickness dimension of the glass sheet, It is known that depending on the thickness of the glass plate, in particular, the thickness dimension changes from the prior art size to the recent thinned size (so-called film size), and the appropriate size (range) of the protruding size is large. The change in amplitude. Therefore, when the second support portion is configured to be detachable from the first support portion, even when a plurality of different types of glass sheets having different thicknesses are processed on the same processing line, only It is necessary to exchange the second support portion, and it is possible to make an appropriate state of support of the glass plate. As a result, it is possible to apply high precision processing to each of the glass plates having different thicknesses.
又，本發明之玻璃板之端部加工裝置，係亦可構成為：當將被支持於支持台處之狀態下的玻璃板之端部之從第2支持部所突出的尺寸設為A〔mm〕，並將玻璃板之厚度尺寸設為t〔mm〕的情況時，係以滿足A<t×200的方式，來設定突出尺寸A。 Further, the end portion processing apparatus for a glass sheet according to the present invention may be configured such that the size of the end portion of the glass sheet in the state of being supported by the support base is set to A from the second support portion. In the case where the thickness of the glass plate is set to t [mm], the protruding dimension A is set so as to satisfy A<t×200.
上述之尺寸設定，特別是在對於厚度尺寸為300μm以下之玻璃板而施加加工時，係為有效。亦即是，若是先前技術之厚度尺寸(700μm或者是此以上)之玻璃板，則就算是突出尺寸為較厚度尺寸之200倍更大(例如300倍程度)，也能夠並不會特別發生變形或震動之問題地而對於端部進行加工。另一方面，若是玻璃板之厚度尺寸成為300μm以下，則係發現到會有出現與先前之厚度尺寸的玻璃板大不相同之舉動的傾向。本發明，係為有鑑於上述傾向而完成者，特別是在對於厚度尺寸為300μm以下之玻璃板而施加加工時，藉由將玻璃板之突 出尺寸設定為上述範圍內，係能夠因應於玻璃板之厚度尺寸而將玻璃板適當地作支持。故而，係能夠對於加工時之玻璃板的變形或震動有效地作抑制，而成為能夠施加高精確度之加工。又，於此情況，藉由如同上述一般地將第2支持部構成為可相對於第1支持部而作裝卸，係能夠以針對各個厚度尺寸而設為相異之突出尺寸的方式，來安裝在適當之尺寸的第2支持部上。藉由此，係成為能夠將300μm以下之範圍內並且厚度尺寸為相異的複數種類之玻璃板，在同一之加工線上而施加高精確度之加工。 The above-described size setting is effective especially when processing is applied to a glass plate having a thickness of 300 μm or less. That is, in the case of the glass plate of the prior art thickness dimension (700 μm or more), even if the protruding dimension is 200 times larger than the thickness dimension (for example, 300 times), it can be not particularly deformed. Or the problem of vibration is processed for the end. On the other hand, when the thickness of the glass plate is 300 μm or less, it is found that there is a tendency that the glass plate is greatly different from the previous thickness. The present invention has been made in view of the above-described tendency, in particular, when a glass plate having a thickness of 300 μm or less is applied, the glass plate is protruded. When the size is set within the above range, the glass plate can be appropriately supported in accordance with the thickness of the glass plate. Therefore, it is possible to effectively suppress deformation or vibration of the glass sheet during processing, and it is possible to apply high precision processing. In this case, the second support portion can be attached to and detached from the first support portion as described above, and can be mounted so as to have different protruding sizes for each thickness dimension. On the second support of the appropriate size. By this, it is possible to apply a plurality of types of glass sheets having a thickness of 300 μm or less and different thicknesses, and apply high precision processing on the same processing line.
當然的，就算是在設為與具備有先前的厚度尺寸之玻璃板之間的混合生產線的情況時，亦同樣的，藉由另外準備會成為先前型態之定盤等一般的形狀以及尺寸之第2支持部，並將此些以手動或自動來進行交換，係成為能夠將先前技術之尺寸的玻璃板和薄化尺寸的玻璃板一同確實且高精確度地進行加工。 Of course, even in the case of being a mixed production line with a glass plate having a previous thickness, the same general shape and size as that of the prior type of the fixed plate are prepared. The second support portion is exchanged manually or automatically, so that the glass plate of the prior art size and the thinned glass plate can be processed with high precision.
又，本發明之玻璃板之端部加工裝置，係亦可構成為：第2支持部，係藉由相較於第1支持部而剛性為更高之材料所形成。 Further, in the end portion processing apparatus for a glass sheet according to the present invention, the second support portion may be formed of a material having a higher rigidity than the first support portion.
第2支持部，若是考慮到使其在將玻璃板之端部側區域作了支持的狀態下而通過蓋部的開口部一事，則其之厚度尺寸係以越小為越理想。另一方面，若是將第2支持部之厚度尺寸設為過小，則係成為難以確保第2支持部自身之剛性。有鑑於以上之點，藉由將第2支持部以相較於第1支持部而剛性為更高之材料來形成，係成為能 夠以在將第2支持部形成為能夠通過蓋部之開口部的程度之厚度尺寸的同時亦可確保第2支持部自身之剛性的適當之大小的厚度尺寸，來形成第2支持部。 When the second support portion is passed through the opening portion of the lid portion in a state in which the end portion side region of the glass sheet is supported, the thickness of the second support portion is preferably as small as possible. On the other hand, if the thickness of the second support portion is too small, it is difficult to ensure the rigidity of the second support portion itself. In view of the above, it is possible to form the second support portion with a material having a higher rigidity than the first support portion. The second support portion can be formed by forming a thickness dimension of the second support portion so as to pass through the opening portion of the lid portion while ensuring the rigidity of the second support portion itself.
又，本發明之玻璃板之端部加工裝置，係亦可構成為將第2支持部之厚度尺寸設定為0.25mm以上4.0m以下，較理想，係亦可構成為將第2支持部之厚度尺寸設定為0.5mm以上2.0m以下。 Further, the end portion processing apparatus for a glass sheet of the present invention may be configured such that the thickness of the second support portion is 0.25 mm or more and 4.0 m or less, and preferably the thickness of the second support portion may be configured. The size is set to be 0.5 mm or more and 2.0 m or less.
基於上述之理由，藉由將第2支持部之厚度尺寸設定為上述之範圍，係能夠使其與玻璃板一同通過蓋部之開口部，並且亦成為能夠確保有所必要的剛性。特別是，當將成為支持台之基部的第1支持部藉由加工性為佳之鋁等來形成的情況時，若是藉由相較於第1支持部而剛性為更高之材料(例如不鏽鋼等)來形成第2支持部，則係能夠將第2支持部的厚度尺寸設定在上述之範圍中的尺寸為較小之區域中，而成為能夠謀求更進一步之加工性(作業性)的提升。 For the reason described above, by setting the thickness dimension of the second support portion to the above range, it is possible to pass the opening portion of the lid portion together with the glass sheet, and it is also possible to ensure the necessary rigidity. In particular, when the first support portion serving as the base portion of the support table is formed of aluminum or the like having good workability, the material having higher rigidity than the first support portion (for example, stainless steel or the like) When the second support portion is formed, the thickness of the second support portion can be set to a smaller size in the above-described range, and further improvement in workability (workability) can be achieved.
又，本發明之玻璃板之端部加工裝置，係能夠對於厚度尺寸被設定為300μm以下之玻璃板而合適地作適用。又，於此情況，若是厚度尺寸變得過小，則從成形技術之觀點來看，由於可以想見玻璃板之成形精確度係會降低，因此，較理想，係盡可能將厚度尺寸設定為5μm以上。當然的，若是在成形技術上並沒有問題，則就算是對於厚度尺寸為更小(未滿5μm)之玻璃板，亦能夠合適地適用本發明。 Further, the end portion processing apparatus for a glass sheet of the present invention can be suitably applied to a glass sheet having a thickness of 300 μm or less. Further, in this case, if the thickness dimension is too small, from the viewpoint of the molding technique, since it is conceivable that the forming accuracy of the glass sheet is lowered, it is preferable to set the thickness dimension to 5 μm as much as possible. the above. Of course, if there is no problem in the forming technique, the present invention can be suitably applied even for a glass plate having a smaller thickness (less than 5 μm).
又，前述課題之解決，係亦可藉由本發明之玻璃板之端部加工方法而達成。亦即是，此端部加工方法，係為用以對於被支持於支持台之狀態的玻璃板之端部而藉由被蓋部所覆蓋的加工部來施加特定之加工之方法，並具備有下述之特徵：亦即是，在蓋部處，係設置有用以使玻璃板之端部和加工部能夠抵接的開口部，支持台，係具備有支持玻璃板之中央側區域的第1支持部、和支持玻璃板之端部側區域之第2支持部，第2支持部之厚度尺寸係被設定為較第1支持部之厚度尺寸更小並且能夠在支持玻璃板之端部側區域的狀態下而通過蓋部的開口部之程度的大小，藉由此，來將支持玻璃板之端部側區域的狀態下之第2支持部插通於開口部中，並進行玻璃板之端部和加工部之間的抵接。 Further, the solution to the above problems can be achieved by the method for processing the end portion of the glass sheet of the present invention. In other words, the end processing method is a method for applying a specific processing to the end portion of the glass sheet supported by the support table by the processing portion covered by the cover portion, and is provided with In the lid portion, an opening portion for allowing the end portion of the glass sheet to be in contact with the processed portion is provided, and the support table is provided with the first side of the center side region of the support glass sheet. The support portion and the second support portion supporting the end portion side region of the glass plate, the thickness of the second support portion is set to be smaller than the thickness of the first support portion and can be at the end side region of the support glass plate In the state of passing through the opening of the lid portion, the second support portion in a state in which the end portion side region of the glass sheet is supported is inserted into the opening portion, and the end of the glass sheet is inserted. The abutment between the part and the processing part.
如此這般，就算是依據本發明之加工方法，亦同樣的，由於係構成為在支持台處，而設置有支持玻璃板之中央側區域的第1支持部、和支持玻璃板之端部側區域的第2支持部，因此，就算是當玻璃板之厚度尺寸為小的情況時，亦能夠確實地支持玻璃板之端部側區域。又，於此情況，由於係將第2支持部之厚度尺寸設定為較第1支持部之厚度尺寸更小並且能夠在支持玻璃板之端部側區域的狀態下而使第2支持部通過蓋部的開口部之程度的大小，因此係能夠在使玻璃板之端部側區域被支持於第2支持部處的狀態下，而謀求該玻璃板之端部和被蓋部所覆蓋的加工部之間的抵接。藉由此，由於係能夠將被導入至蓋 部內的玻璃板之包含有接近於端部之區域的端部側區域之大部分，從加工開始前起便作支持，因此係能夠對於在與加工部相抵接時之玻璃板的變形作抑制，並且係能夠對起因於研削液之吹附等所導致的玻璃板之震動作抑制，而成為能夠進行高精確度之加工。又，藉由對於變形或震動作抑制，係能夠避免蓋部之開口部和玻璃板之間的間隙發生大幅度變動之事態。故而，係將間隙維持於特定之大小，而成為能夠盡可能地防止研削液等之液體飛散至玻璃板之表面中央側處並附著的事態。 In this manner, even in the processing method according to the present invention, the first support portion for supporting the center side region of the glass sheet and the end portion side of the supporting glass plate are provided in the support stand. Since the second support portion of the region is such that the thickness of the glass plate is small, the end portion side region of the glass plate can be surely supported. In this case, the thickness of the second support portion is set to be smaller than the thickness of the first support portion, and the second support portion can be passed through the cover while the end portion side region of the glass plate is supported. In the state in which the end portion of the glass sheet is supported by the second support portion, the end portion of the glass sheet and the processed portion covered by the lid portion can be obtained in a state where the end portion of the glass sheet is supported by the second support portion. The abutment between. By this, since the system can be introduced into the cover The glass plate in the inside portion contains a large portion of the end portion side region close to the end portion, and is supported from the start of the processing, so that the deformation of the glass sheet at the time of abutment with the processed portion can be suppressed. Further, it is possible to suppress the vibration of the glass sheet caused by the blowing of the grinding liquid or the like, and it is possible to perform processing with high precision. Further, by suppressing the deformation or the vibration, it is possible to avoid a situation in which the gap between the opening portion of the lid portion and the glass sheet greatly changes. Therefore, the gap is maintained at a specific size, and it is possible to prevent the liquid such as the grinding liquid from scattering to the center side of the surface of the glass sheet as much as possible.
如同以上所述一般，若依據本發明，則就算是身為厚度尺寸相較於先前技術而為更小的玻璃板，也能夠在將其之端部側區域作了支持的狀態下而通過蓋部的開口部，並使玻璃板之端部與加工部相抵接。故而，係成為能夠盡可能地防止玻璃板之變形以及對於玻璃板表面之液體的附著，而以高精確度來對於玻璃板之端部施加加工。 As described above, according to the present invention, even if it is a glass plate having a thickness smaller than that of the prior art, it can be passed through the cover while supporting the end side region thereof. The opening of the portion and the end portion of the glass plate are brought into contact with the processed portion. Therefore, it is possible to prevent the deformation of the glass sheet and the adhesion to the liquid on the surface of the glass sheet as much as possible, and to apply the processing to the end portion of the glass sheet with high precision.

以下，參考圖1~圖4，針對本發明之玻璃板之端部加工裝置的第1實施形態作說明。另外，在以下之說明中的「上下方向」，係為為了能夠容易地理解說明所隨便設定者，而並非為對於實際之使用形態作限定者。 Hereinafter, a first embodiment of an end portion processing apparatus for a glass sheet according to the present invention will be described with reference to Figs. 1 to 4 . In addition, in the following description, the "up-and-down direction" is a person who can easily understand the description, and is not limited to the actual use form.
圖1，係為用以對於本發明之第1實施形態的玻璃板之端部加工裝置之概要作展示的平面圖。此端部加工裝置10，例如係為用以對於從成形後之母玻璃板而藉由切斷或割斷等來分割成特定之形狀所得到之玻璃板G的端部Ge而施加特定之加工的裝置，並具備有支持玻璃板之支持台11、和用以對於被支持於支持台11處的狀態下之玻璃板G之端部Ge施加特定之加工的加工單元12。在本實施形態中，加工單元12係為研削單元，並藉由一面使被設置在加工單元12內之作為加工部的砥石13沿著被切斷成矩形等所得到的玻璃板G之端部Ge(邊緣部)作相對移動一面使該砥石13抵接於端部Ge處，而能夠對於端部Ge施加研削加工。 Fig. 1 is a plan view showing an outline of an end portion processing apparatus for a glass sheet according to a first embodiment of the present invention. The end processing device 10 is, for example, applied to apply the specific processing to the end Ge of the glass sheet G obtained by dividing into a specific shape from the formed mother glass sheet by cutting or cutting. The apparatus is provided with a support table 11 having a supporting glass plate, and a processing unit 12 for applying a specific process to the end Ge of the glass sheet G in a state supported by the support table 11. In the present embodiment, the processing unit 12 is a grinding unit, and the end portion of the glass sheet G obtained by cutting the rectangular portion 13 which is the processed portion in the processing unit 12 into a rectangular shape or the like is formed. The Ge (edge portion) is relatively moved while the vermiculite 13 abuts against the end portion Ge, and the grinding process can be applied to the end portion Ge.
於此，玻璃板G，例如係藉由矽酸鹽玻璃、氧化矽玻璃等所形成，較理想，係藉由硼矽酸玻璃所形 成，更理想，係藉由無鹼玻璃所形成。若是在玻璃板G中包含有鹼性成分，則可能會於其之表面上發生陽離子之脫離、亦即是發生所謂的碳酸鈉溢出的現象。於此情況，由於在玻璃板G中係會產生構造性地變得粗糙的部份，因此，若是在使此玻璃板G作了彎曲的狀態下來使用，則會有起因於歷年劣化而以變得粗糙的部份作為起點並導致破損之虞。基於以上之理由，當有可能會以非平坦狀態來使用玻璃板G的情況時，係以使用無鹼玻璃來形成玻璃板G為適當。 Here, the glass plate G is formed, for example, by bismuth silicate glass, yttria glass, or the like, and is preferably formed by borosilicate glass. It is more ideal, formed by alkali-free glass. If the alkaline component is contained in the glass plate G, cation detachment may occur on the surface thereof, that is, a phenomenon called so-called sodium carbonate overflow occurs. In this case, since the structurally roughened portion is formed in the glass sheet G, if the glass sheet G is used in a state of being bent, it may be changed due to deterioration over the years. The rough part is used as a starting point and causes damage. For the above reasons, when it is possible to use the glass sheet G in a non-flat state, it is appropriate to form the glass sheet G using alkali-free glass.
另外，於此之所謂無鹼玻璃，係指實質上並未包含有鹼性成分(鹼金屬氧化物)之玻璃，具體而言，係指鹼性成分為3000ppm以下之玻璃。當然的，從盡可能地防止或者是減輕起因於上述之理由所導致的歷年劣化之觀點來看，係以1000ppm以下之玻璃為理想，又以500ppm以下之玻璃為更理想，又以300ppm以下之玻璃為更加理想。 In addition, the term "alkali-free glass" as used herein means a glass which does not substantially contain an alkaline component (alkali metal oxide), and specifically refers to a glass having an alkaline component of 3,000 ppm or less. Of course, it is preferable to prevent or reduce the deterioration of the calendar due to the above reasons as much as possible, and it is preferable to use glass of 1000 ppm or less, and more preferably 500 ppm or less, and more preferably 300 ppm or less. Glass is more ideal.
玻璃板G之厚度尺寸，係被設定為300μm以下，較理想係被設定為200μm以下，更理想係被設定為100μm以下。針對厚度尺寸之下限值，雖然可並無特別限制地來設定，但是，若是對於成形精確度或者是成形後之處理性等作考慮，則係設定為1μm以上，較理想係設定為5μm以上。 The thickness of the glass plate G is set to 300 μm or less, more preferably 200 μm or less, and more preferably 100 μm or less. The lower limit of the thickness is not particularly limited, but it is set to 1 μm or more, and more preferably 5 μm or more, in consideration of molding accuracy or rationality after molding. .
又，玻璃板G之與支持台11相反側的表面Ga之表面粗度Ra的大小，係並未特別作限定。例如，當 想定為施加成膜等之關連於電子裝置之處理的情況時，其之表面粗度Ra係以身為2.0nm以下為理想，又以身為1.0nm以下為更理想，又以身為0.2nm以下為更加理想。 Further, the surface roughness Ra of the surface Ga on the side opposite to the support table 11 of the glass sheet G is not particularly limited. For example, when When the film or the like is applied to the treatment of the electronic device, the surface roughness Ra is preferably 2.0 nm or less, more preferably 1.0 nm or less, and 0.2 nm. The following is more ideal.
上述之玻璃板G，係藉由下引(down draw)法等之公知之成形方法所成形，較理想，係藉由溢流下引法來成形。又，亦可藉由漂浮法或流孔下引法、輥出(roll out)法、上引(up draw)法等來成形。另外，亦可因應於需要而施加二次加工(藉由再曳引來將玻璃一次成形體拉伸)，並設定為未滿100μm之厚度尺寸。 The glass plate G described above is formed by a known forming method such as a down draw method, and is preferably formed by an overflow down-draw method. Further, it may be formed by a floatation method, a flow-down method, a roll out method, an up draw method, or the like. Further, secondary processing may be applied as needed (the glass primary molded body is stretched by re-drawing) and set to a thickness of less than 100 μm.
加工單元12，係如同圖2中所示一般，具備有砥石13、和旋轉驅動砥石13之旋轉驅動部14、和升降驅動砥石13之升降驅動部15、和覆蓋砥石13之蓋部16、和用以使砥石13以及蓋部16能夠水平移動之水平移動驅動部17。此些之驅動部，係以高精確度之位置控制作為目的，而例如藉由伺服馬達所構成，但是，當然的，係亦可藉由其以外之驅動手段(汽缸等之各種致動器)來構成。又，雖係省略圖示，但是，加工單元12，係亦可為更進而具備有朝向玻璃板G之端部Ge和砥石13之間的抵接部或者是其周邊而供給研削液(例如純水)之研削液供給部者。此研削液供給部，係可被配設在蓋部16之內側，亦可被配設在蓋部16之外側。 The processing unit 12 is provided with a vermiculite 13 and a rotary drive unit 14 for rotationally driving the vermiculite 13, a lifting drive unit 15 for lifting and lowering the rock 13, and a cover portion 16 covering the vermiculite 13, and The drive unit 17 is moved horizontally to allow the vermiculite 13 and the lid portion 16 to move horizontally. Such a drive unit is for the purpose of high-accuracy position control, and is constituted by, for example, a servo motor. However, it is of course possible to use other driving means (various actuators such as cylinders). Come to form. Further, although not shown, the processing unit 12 may further include a grinding fluid (for example, pure) including an abutting portion between the end portion Ge of the glass sheet G and the vermiculite 13 or the periphery thereof. The grinding liquid supply unit of water). The grinding fluid supply unit may be disposed inside the lid portion 16 or may be disposed on the outer side of the lid portion 16.
砥石13，係於其之外周，具備有與應對於玻璃板G之端部Ge施加的加工內容相對應之形狀的砥面18。在本實施形態中，砥面18，係藉由用以對於端部Ge 施加單側去角的斜面所構成。另外，砥面18，在本圖示例中雖係為了達成維修間隔之長期化而在砥石13之外周處設置有複數，但是，當然的，係亦可僅設置有1個的砥面18。於此情況，升降驅動部15，係亦可為使砥石13相對於蓋部16而作升降者，亦可為使砥石13和蓋部16一體性地作升降者。又，關於砥面18之形狀，亦可因應於加工內容(於此係為研削內容)而適宜設定之。 The vermiculite 13 is provided on the outer periphery thereof, and has a dome surface 18 having a shape corresponding to the processing content to be applied to the end Ge of the glass sheet G. In this embodiment, the facet 18 is used for the end Ge It is composed of a beveled surface with a single side chamfer. In addition, in the example of the figure, although the plural is provided in the outer periphery of the vermiculite 13 in order to achieve the long-term maintenance interval, it is needless to say that only one kneading surface 18 is provided. In this case, the elevation drive unit 15 may be such that the vermiculite 13 is lifted and lowered with respect to the lid portion 16, and the vermiculite 13 and the lid portion 16 may be integrally lifted and lowered. Further, the shape of the kneading surface 18 can be appropriately set in accordance with the processing content (this is the grinding content).
在蓋部16處，係設置有用以使成為加工對象之玻璃板G的端部Ge能夠與砥石13相抵接的開口部19。若是作詳細敘述，則此開口部19，係被形成在蓋部16中之與支持台11相對向的部位處，並成為朝向砥石13之相對移動方向而貫通蓋部16的形狀(圖1以及圖2)。又，開口部19之開口寬幅尺寸w，係被設定為能夠使後述之支持台11的一部分和玻璃板G通過並且能夠確實地避免在加工時之玻璃板G等與蓋部16之間的相互干涉之程度的大小。 In the lid portion 16, an opening portion 19 for allowing the end portion Ge of the glass sheet G to be processed to abut against the vermiculite 13 is provided. As will be described in detail, the opening portion 19 is formed in a portion of the lid portion 16 facing the support base 11, and has a shape that penetrates the lid portion 16 toward the relative movement direction of the vermiculite 13 (Fig. 1 and figure 2). In addition, the opening width w of the opening 19 is set so that a part of the support table 11 to be described later and the glass sheet G can pass, and it is possible to surely avoid the between the glass sheet G and the like and the lid portion 16 during processing. The degree of mutual interference.
支持台11，係為具備有支持玻璃板G之中央側區域G1的第1支持部20、和支持玻璃板G之端部側區域G2的第2支持部21者，第2支持部21之厚度尺寸ts係被設定為較第1支持部20之厚度尺寸更小。在本實施形態中，支持台11，係作為構成要素，而包含有板狀構件22、和被與此板狀構件22相互獨立地形成並且將板狀構件22安裝於段部處的基台23。藉由此，板狀構件22主要係作為第2支持部21而起作用，並且基台23主要係 作為第1支持部20而起作用。在此圖示例中，板狀構件22由於係具備有對於基台23之安裝部位，因此，係並不僅是作為第2支持部21而起作用，而亦作為第1支持部20而起一部分的作用。亦即是，板狀構件22係作為第2支持部21之全體以及第1支持部20之一部分(端部側)而起作用，基台23係成為作為第1支持部20之殘部(中央側)而起作用。又，第2支持部21之形狀，係被設為與玻璃板G之四個的邊緣部相對應的形狀(具備有4個的角部之框體狀)(圖1)。故而，構成第2支持部21之一大部分的板狀構件22，係亦同樣的被設為具備有四個的角部之框體狀。 The support table 11 is a thickness of the second support portion 21 including the first support portion 20 having the center side region G1 supporting the glass sheet G and the second support portion 21 supporting the end portion side region G2 of the glass sheet G. The size ts is set to be smaller than the thickness dimension of the first support portion 20. In the present embodiment, the support table 11 includes, as constituent elements, a plate-like member 22, and a base 23 which is formed independently of the plate-shaped member 22 and which mounts the plate-like member 22 at the segment portion. . Thereby, the plate member 22 mainly functions as the second support portion 21, and the base 23 is mainly It functions as the first support unit 20. In the example of the figure, since the plate-shaped member 22 is provided with the attachment portion to the base 23, it functions not only as the second support portion 21 but also as the first support portion 20. The role. In other words, the plate-shaped member 22 functions as a part of the second support portion 21 and a part (end portion side) of the first support portion 20, and the base 23 serves as a residual portion of the first support portion 20 (center side) ) and work. In addition, the shape of the second support portion 21 is a shape corresponding to the edge portions of the four glass sheets G (a frame shape having four corner portions) (FIG. 1). Therefore, the plate-like member 22 constituting most of the second support portion 21 is similarly formed in a frame shape having four corner portions.
又，支持台11，係亦可為更進而具備有保持玻璃板G並防止加工時之位置偏移的位置偏移防止手段者。在本實施形態中，吸附保持部27係被設置在支持台11(基台23)處，該吸附保持部27，係藉由於被設置在第1支持部20之上側處的支持面24處而開口之1或複數之孔部25、和用以透過孔部25而進行吸氣之吸氣部26，而構成之。藉由此，來成為能夠將被載置在支持面24上之玻璃板G作吸附保持。其中，孔部25，例如係以被配設在能夠吸附玻璃板G之中央側區域G1的位置處為理想。 Further, the support table 11 may be provided with a positional deviation preventing means for holding the glass sheet G and preventing positional displacement during processing. In the present embodiment, the adsorption holding portion 27 is provided on the support table 11 (base 23) which is provided at the support surface 24 at the upper side of the first support portion 20 The opening 1 or a plurality of holes 25 and the intake portion 26 for inhaling through the hole portion 25 are formed. Thereby, the glass plate G placed on the support surface 24 can be adsorbed and held. Among these, it is preferable that the hole portion 25 is disposed at a position where the center side region G1 of the glass sheet G can be adsorbed, for example.
於此，第2支持部21之厚度尺寸ts，係亦可為在維持上述之大小關係的前提下而因應於玻璃板G之厚度尺寸tg所適宜設定者。具體而言，第2支持部21之厚 度尺寸ts，係亦可為以會滿足tg〔mm〕×0.1≦ts〔mm〕的方式所設定者。藉由此，係成為能夠確保第2支持部21自身之剛性，並更確實地抑制玻璃板G之變形。但是，若是第2支持部21過厚，則由於係會成為難以在支持有玻璃板的狀態下來並不發生任何之干涉地而通過蓋部16的開口部19，因此，係亦能夠以會滿足ts〔mm〕≦tg〔mm〕×10的方式，來設定第2支持部21之厚度尺寸ts。 Here, the thickness dimension ts of the second support portion 21 may be appropriately set in accordance with the thickness dimension tg of the glass sheet G while maintaining the above-described magnitude relationship. Specifically, the thickness of the second support portion 21 is The degree size ts may be set in such a manner as to satisfy tg [mm] × 0.1 ≦ ts [mm]. As a result, the rigidity of the second support portion 21 itself can be ensured, and the deformation of the glass sheet G can be more reliably suppressed. However, if the second support portion 21 is too thick, it is difficult to pass through the opening portion 19 of the cover portion 16 without any interference in a state in which the glass plate is supported, and therefore, the system can satisfy The thickness dimension ts of the second support portion 21 is set in a manner of ts [mm] ≦ tg [mm] × 10.
有鑑於以上因素，當玻璃板G之厚度尺寸tg為300μm以下的情況時，第2支持部21之厚度尺寸ts，具體而言，係可為被設定為0.25mm以上4.0mm以下者，較理想，係可為被設定為0.5mm以上2.0mm以下者。藉由將第2支持部21之厚度尺寸ts設定為上述之範圍，係能夠使其與玻璃板G一同通過蓋部16之開口部19，並且亦成為能夠確保有所必要的剛性。 In view of the above, when the thickness dimension tg of the glass sheet G is 300 μm or less, the thickness dimension ts of the second support portion 21 may be set to be 0.25 mm or more and 4.0 mm or less. The system may be set to be 0.5 mm or more and 2.0 mm or less. By setting the thickness dimension ts of the second support portion 21 to the above range, it is possible to pass the opening portion 19 of the lid portion 16 together with the glass sheet G, and it is also possible to ensure the necessary rigidity.
又，在設定被支持於支持台11處之狀態下的玻璃板G之端部側區域G2之從第2支持部21所突出的尺寸Lg〔mm〕時，係亦能夠以滿足Lg〔mm〕<tg〔mm〕×200的方式，來設定突出尺寸Lg。 In addition, when the size Lg [mm] protruding from the second support portion 21 of the end portion side region G2 of the glass sheet G in the state of being supported by the support table 11 is set, it is also possible to satisfy Lg [mm]. In the manner of <tg [mm] × 200, the protruding size Lg is set.
又，有鑑於以上因素，當玻璃板G之厚度尺寸tg為300μm以下的情況時，玻璃板G之突出尺寸Lg，具體而言，係被設定為0.5mm以上20mm以下，較理想，係被設定為1.0mm以上10mm以下者。藉由將突出尺寸Lg設定在上述之範圍內，就算是在玻璃板G之厚度 尺寸tg相較於先前技術而為小(300μm以下)的情況時，亦成為能夠將玻璃板G安定地作支持。 In the case where the thickness dimension tg of the glass sheet G is 300 μm or less, the protruding dimension Lg of the glass sheet G is specifically set to 0.5 mm or more and 20 mm or less, and is preferably set. It is 1.0mm or more and 10mm or less. By setting the protruding dimension Lg within the above range, even in the thickness of the glass plate G When the size tg is smaller than the prior art (300 μm or less), the glass sheet G can be stably supported.
另外，在本實施形態中，如同圖1中所示一般，在玻璃板G之四個的邊緣部之全部處，玻璃板G均係從支持台11而突出，但是，當然的，因應於加工單元12之設置形態等，係亦可採用在1個或2個或者是3個的邊緣部處而使玻璃板G從支持台11突出的形態。 Further, in the present embodiment, as shown in Fig. 1, the glass sheets G are all protruded from the support table 11 at all of the edge portions of the four glass sheets G, but of course, due to processing In the form of the unit 12 or the like, the glass sheet G may be protruded from the support table 11 at one or two or three edge portions.
另外，針對第2支持部21之從第1支持部20突出的突出尺寸Ls，亦同樣的，係以因應於所應支持之玻璃板G之厚度尺寸tg來設定為理想，具體而言，當玻璃板G之厚度尺寸tg為300μm以下的情況時，突出尺寸Ls係以為被設定為10mm以上50mm以下為理想，更理想，係被設定為15mm以上35mm以下。 In addition, the protruding dimension Ls of the second support portion 21 protruding from the first support portion 20 is similarly set in accordance with the thickness dimension tg of the glass sheet G to be supported, specifically, when When the thickness dimension tg of the glass plate G is 300 μm or less, the protruding dimension Ls is preferably set to 10 mm or more and 50 mm or less, and more preferably 15 mm or more and 35 mm or less.
接著，針對使用有上述構成之端部加工裝置10的研削加工之其中一例，與本發明之優點一同作說明。 Next, an example of the grinding process using the end portion processing apparatus 10 having the above configuration will be described together with the advantages of the present invention.
首先，從圖3中所示之狀態起，使加工單元12之水平移動驅動部17驅動，而使砥石13以及蓋部16朝向支持台11作接近移動。在本實施形態中，係在將加工單元12配設在從應加工之玻璃板G的端部Ge而有所偏離的位置(並不會相互對向的位置)處之後，使砥石13以及蓋部16一直水平移動至端部Ge之假想延長線上為止(圖1中之以2點鍊線所示之位置)。之後，使加工單元12逐漸接近玻璃板G之端部Ge，並使其與端部Ge 之長邊方向其中一端部Ge1(圖1)相抵接。此時，砥石13之砥面18，係預先藉由升降驅動部15，而被設定於與應加工之玻璃板G之端部Ge相同的高度準位處。在對於與玻璃板G之厚度尺寸tg互為相異之玻璃板tg進行加工時，係因應於其之厚度尺寸tg而對於砥面18作調整。又，砥石13係藉由旋轉驅動部14而被以特定之旋轉數作旋轉。藉由此，係對於玻璃板G之端部Ge施加研削加工，該端部Ge係被最終加工為準據於砥面18之形狀(圖4)。在本實施形態中，由於砥面18係藉由錐狀之斜面所構成，因此，藉由上述加工，係僅有端部Ge之上側會被施加錐狀之去角(單側去角)。之後，藉由從此狀態起而使砥石13沿著端部Ge之長邊方向逐漸移動，玻璃板G之端部Ge係涵蓋其之長邊方向全區域地而被施加研削加工，並被最終加工為如同上述一般之形狀。 First, from the state shown in FIG. 3, the horizontal movement driving portion 17 of the machining unit 12 is driven to move the vermiculite 13 and the lid portion 16 toward the support table 11. In the present embodiment, after the machining unit 12 is disposed at a position deviated from the end Ge of the glass sheet G to be processed (a position that does not face each other), the vermiculite 13 and the cover are provided. The portion 16 is horizontally moved up to the imaginary extension line of the end Ge (the position shown by the 2-point chain line in Fig. 1). Thereafter, the processing unit 12 is gradually brought closer to the end Ge of the glass sheet G, and is made to be opposite to the end Ge. One end portion Ge1 (Fig. 1) abuts in the longitudinal direction. At this time, the top surface 18 of the vermiculite 13 is set to the same height level as the end Ge of the glass sheet G to be processed by the elevation drive unit 15 in advance. When the glass sheet tg which is different from the thickness tg of the glass sheet G is processed, the surface 18 is adjusted in accordance with the thickness dimension tg thereof. Further, the vermiculite 13 is rotated by a specific number of rotations by the rotation driving unit 14. Thereby, a grinding process is applied to the end Ge of the glass sheet G, and the end Ge is finally processed to the shape of the top surface 18 (FIG. 4). In the present embodiment, since the meandering surface 18 is formed by a tapered inclined surface, only the upper side of the end portion Ge is subjected to a tapered chamfer (one-side chamfering) by the above-described processing. Thereafter, the vermiculite 13 is gradually moved along the longitudinal direction of the end Ge from this state, and the end Ge of the glass sheet G is subjected to grinding processing in the entire longitudinal direction of the glass sheet G, and is finally processed. It is a general shape like the above.
此時，第2支持部21之厚度尺寸ts，係被設定為較第1支持部20之厚度尺寸更小，並且被設定為能夠在將玻璃板G作了支持的狀態下而與玻璃板G一同地插通於蓋部16的開口部19之程度的大小。藉由此，第2支持部21係能夠與玻璃板G一同地而並不與開口部19發生任何之干涉地來通過，並使玻璃板G之端部Ge與砥石13相互抵接。又，如同圖4中所示一般，在使玻璃板G之端部Ge與砥石13之砥面18作了抵接的狀態下，開口部19和玻璃板G之上側之表面Ga之間的間隙C，係被維持於5mm以下。藉由此，係能夠對於從未圖示之研削液 供給部而朝向玻璃板G與砥石13之間的抵接部或者是其之周邊所供給並飛散的研削液通過此間隙C並到達表面Ga處而發生附著的事態有效地作防止。但是，若是此間隙C過小，則由於會有發生玻璃板G和開口部19之間的干涉之虞，因此，間隙C係以至少確保有1mm以上為理想。 At this time, the thickness dimension ts of the second support portion 21 is set to be smaller than the thickness dimension of the first support portion 20, and is set so as to be able to support the glass sheet G with the glass sheet G. The size of the opening portion 19 of the lid portion 16 is inserted together. By this, the second support portion 21 can pass through together with the glass plate G without any interference with the opening portion 19, and the end portion Ge of the glass sheet G and the vermiculite 13 can abut each other. Further, as shown in Fig. 4, in the state where the end portion Ge of the glass sheet G is brought into contact with the top surface 18 of the vermiculite 13, the gap between the opening portion 19 and the surface Ga on the upper side of the glass sheet G is obtained. C is maintained at 5 mm or less. By this, it is possible to use a grinding fluid not shown. The supply unit is effectively prevented from being in contact with the contact portion between the glass sheet G and the vermiculite 13 or the grinding fluid supplied and scattered around the gap C through the gap C and reaching the surface Ga. However, if the gap C is too small, interference between the glass sheet G and the opening 19 may occur. Therefore, it is preferable that the gap C is at least 1 mm or more.
又，在本實施形態中，在設定被支持於支持台11處之狀態下的玻璃板G之端部側區域G2之從第2支持部21所突出的尺寸Lg〔mm〕時，係以滿足Lg〔mm〕<tg〔mm〕×200的方式，來設定突出尺寸Lg。藉由此，特別是在對於厚度尺寸為300μm以下之玻璃板G而施加加工時，藉由將玻璃板G之突出尺寸Lg設定為上述範圍內，係能夠因應於玻璃板G之厚度尺寸tg而將玻璃板G適當地作支持。故而，係能夠對於加工時之玻璃板G的變形或震動有效地作抑制，而成為能夠施加高精確度之加工。 In the present embodiment, when the dimension Lg [mm] protruding from the second support portion 21 of the end portion side region G2 of the glass sheet G in the state of being supported by the support table 11 is set, it is satisfied. In the manner of Lg [mm] < tg [mm] × 200, the protruding size Lg is set. By applying the processing to the glass sheet G having a thickness of 300 μm or less, in particular, by setting the protruding dimension Lg of the glass sheet G within the above range, it is possible to respond to the thickness dimension tg of the glass sheet G. The glass plate G is suitably supported. Therefore, it is possible to effectively suppress deformation or vibration of the glass sheet G during processing, and it is possible to apply high precision processing.
若是如此這般地而結束了玻璃板G之1個的端部Ge(邊緣部)之研削加工，則係使加工單元12移動至與相鄰接之其他之端部(邊緣部)相對向的位置處，並藉由反覆進行上述之動作，而針對其他之端部亦施加同樣的研削加工。藉由此，係對於玻璃板G之4個的端部(邊緣部)全部而施加特定之研削加工(單側去角加工)，研削加工係結束。 If the grinding of the end Ge (edge portion) of one of the glass sheets G is completed as described above, the processing unit 12 is moved to face the other end portions (edge portions) adjacent thereto. At the position, by repeating the above-described operations, the same grinding process is applied to the other end portions. As a result, a specific grinding process (one-side chamfering) is applied to all of the four end portions (edge portions) of the glass sheet G, and the grinding processing system is completed.
如同上述一般，藉由將主要構成第2支持部 21之板狀構件22，與主要構成第1支持部20之基台23，此兩者相互獨立地而形成之，係能夠將要求用來支持玻璃板G之中央側區域G1的第1支持部20、和要求用來支持玻璃板G之端部側區域G2的第2支持部21，設為相異之規格。藉由此，係能夠防止各個的支持部20、21成為過高之規格，並成為能夠在將各支持部20、21之製作成本抑制為低的同時亦以高精確度來進行最後加工。例如，係能夠將佔據支持台11之大部分並且為了將吸附保持部27等作安裝而成為需要加工成複雜之形狀的基台23，藉由具有較佳加工性並且較為廉價之鋁或者是鋁合金來形成，另一方面，係成為能夠將要求能夠同時達成薄化以及剛性之需求的第2支持部21，藉由不鏽鋼或鈦等之高剛性材料來形成。 As in the above, by mainly constituting the second support unit The plate-shaped member 22 of 21 and the base 23 which mainly constitutes the first support portion 20 are formed independently of each other, and the first support portion required to support the center-side region G1 of the glass sheet G can be used. 20. The second support portion 21 required to support the end side region G2 of the glass sheet G is set to a different size. By this, it is possible to prevent the respective support portions 20 and 21 from being oversized, and it is possible to perform final processing with high accuracy while suppressing the manufacturing cost of each of the support portions 20 and 21 to be low. For example, it is possible to occupy a large portion of the support table 11 and to mount the adsorption holding portion 27 and the like into a base 23 which needs to be processed into a complicated shape, by aluminum or aluminum which has preferable workability and is relatively inexpensive. The alloy is formed, and on the other hand, the second support portion 21, which is required to be able to simultaneously achieve thinning and rigidity, is formed of a highly rigid material such as stainless steel or titanium.
又，藉由將第2支持部21構成為可相對於第1支持部20而作裝卸，就算是在將厚度尺寸tg為相異之複數種類之玻璃板G在同一之加工線上進行加工的情況時，也僅需要對於第2支持部21作交換，便能夠作出適當的玻璃板G之支持狀態。藉由此，係成為能夠對於厚度尺寸為相異之玻璃板G的各者而分別施加高精確度之加工。 In addition, when the second support portion 21 is configured to be detachable from the first support portion 20, it is considered that the plurality of types of glass sheets G having different thicknesses tg are processed on the same processing line. In this case, it is only necessary to exchange the second support portion 21, and it is possible to provide an appropriate state of support of the glass sheet G. As a result, it is possible to apply high precision processing to each of the glass plates G having different thicknesses.
以上，雖係針對本發明之玻璃板之端部加工裝置以及端部加工方法的第1實施形態作了說明，但是，當然的，此加工裝置以及加工方法，在本發明之範圍內，係可採用任意之形態。 In the above, the first embodiment of the end portion processing apparatus and the end portion processing method of the glass sheet of the present invention has been described. However, it is needless to say that the processing apparatus and the processing method are within the scope of the present invention. Use any form.
例如，在上述實施形態中，雖係針對將第2支持部21和第1支持部20形成為相互獨立之個體(將支持台11藉由板狀構件22和基台21來以相互獨立之個體而形成)的情況作了例示，但是，當然的，係亦可將支持台11作為一體性之物品來形成。圖5，係對於本發明之第2實施形態的端部加工裝置10'之重要部分剖面圖作展示。此端部加工裝置10'，係為將第2支持部21和第1支持部20一體性地形成所成者。如此這般，藉由將第2支持部21與第1支持部22一體性地形成，由於係能夠將支持台11設為一體性之物品，因此，相較於設為相互獨立之個體的情況，係成為能夠得到更高的尺寸精確度。當然的，於此情況，亦同樣的，第2支持部21，係可形成為具備有四個的角部之框體狀。 For example, in the above-described embodiment, the second support portion 21 and the first support portion 20 are formed as separate entities (the support table 11 is independent of each other by the plate member 22 and the base 21). The case of formation is exemplified, but of course, the support table 11 may be formed as an integral article. Fig. 5 is a cross-sectional view showing an essential part of an end portion processing apparatus 10' according to a second embodiment of the present invention. The end processing device 10' is formed by integrally forming the second support portion 21 and the first support portion 20. In this way, by integrally forming the second support portion 21 and the first support portion 22, since the support table 11 can be integrated as an article, it is compared with the case where the individual is independent of each other. , to become able to get higher dimensional accuracy. Of course, in this case as well, the second support portion 21 can be formed in a frame shape having four corner portions.
另外，在上述實施形態中，雖係針對使加工單元12移動並使支持台11作了接地固定的情況來作了例示，但是，當然的，係並不被限定於此形態。例如，亦可採用將加工單元12作接地固定並使支持台11藉由未圖示之驅動手段來移動的形態。於此情況，藉由採用能夠使支持台11在鉛直軸周圍作旋轉的構成，就算是在將加工單元12作了接地固定的狀態下，亦成為能夠對於玻璃板G之4個的端部(邊緣部)之全部施加加工。 Further, in the above-described embodiment, the case where the processing unit 12 is moved and the support table 11 is grounded is exemplified, but it is of course not limited to this. For example, the processing unit 12 may be fixed to the ground and the support table 11 may be moved by a driving means (not shown). In this case, by adopting a configuration in which the support table 11 can be rotated around the vertical axis, even when the machining unit 12 is grounded and fixed, it is possible to form four ends of the glass sheet G ( All of the edges are applied.
又，在上述實施形態中，雖係針對藉由設置有錐狀形狀之砥面18的砥石13來進行端部Ge之研削加工(單側去角加工)的情況作了例示，但是，當然的，係 亦可採用此以外之加工形態。例如，藉由將砥面18設為兩側去角用之形狀，並使此砥面18與端部Ge之全面作砥接，係亦能夠對於端部Ge施加兩側去角加工。又，當然的，去角形狀亦為任意(R形狀等)。 Further, in the above-described embodiment, the case where the end Ge is ground (one-side chamfering) is exemplified for the vermiculite 13 provided with the tapered top surface 18, but of course, ,system It is also possible to use other processing forms. For example, by making the facet 18 a shape for both sides of the corner and making the face 18 and the end Ge completely spliced, it is also possible to apply a two-sided chamfering process to the end Ge. Further, of course, the shape of the chamfer is also arbitrary (R shape or the like).
又，在上述實施形態中，作為對於玻璃板G所施加之加工，雖係針對使用有砥石13之研削加工作了例示，但是，當然的，係亦可對於使用有此以外之工具的端部Ge之加工等，而適用本發明。例如，雖係省略圖示，但是，係亦可在使用有膠帶和皮帶之研削(研磨)加工、蝕刻加工等之中，而適用本發明。作為其中一例，當施加蝕刻加工的情況時，係可採用藉由一面使含浸有蝕刻液之海綿滾輪作旋轉一面使該滾輪抵接於端部Ge處，來對於端部Ge施加蝕刻處理，並在端部Ge處形成R去角部的方法。又，作為使用有膠帶和皮帶之研削方法，例如係可使用在日本特開2008-264914號公報或日本特開平5-329760號公報中所揭示之方法以及裝置。 Further, in the above-described embodiment, the processing applied to the glass sheet G is exemplified for the grinding processing using the vermiculite 13, but it is of course possible to use the end portion of the tool other than the above. The processing of Ge, etc., is applicable to the present invention. For example, although not shown in the drawings, the present invention can be applied to grinding (polishing) processing, etching processing, and the like using a tape and a belt. As an example, when an etching process is applied, an etching process may be applied to the end portion Ge by abutting the roller at the end Ge while rotating the sponge roller impregnated with the etching liquid.
