Description

基板の貼合装置及び積層体の製造方法並びに画像表示装置の製造方法Substrate laminating apparatus, laminate manufacturing method, and image display apparatus manufacturing method
　本発明は、基板の貼合装置及び積層体の製造方法並びに画像表示装置の製造方法に関する。 The present invention relates to a substrate bonding apparatus, a laminate manufacturing method, and an image display apparatus manufacturing method.
　近年、建築物の窓ガラス（以下、この窓ガラスを第１の基板とも称する。）に、粘着層を介して画像表示パネル（例えば、液晶パネル。以下、この画像表示パネルを第２の基板とも称する。）を貼合することにより、現場にてデジタルサイネージ（画像表示装置）を組み立てることが検討されている。このデジタルサイネージによれば、通行人は、店舗、オフィスの外部から窓ガラスを介して液晶パネルの表示内容を確認できるため、看板、広告等として有効利用することができる。 In recent years, an image display panel (for example, a liquid crystal panel. This image display panel is also referred to as a second substrate) via an adhesive layer on a window glass of a building (hereinafter, this window glass is also referred to as a first substrate). Assembling a digital signage (image display device) at the site is being studied. According to this digital signage, a passer-by can check the display content of the liquid crystal panel from the outside of the store or office through the window glass, and can be used effectively as a signboard, an advertisement, or the like.
　ところで、上記形態のデジタルサイネージでは、貼合時に、窓ガラスと液晶パネルとの間の粘着層界面に気泡を巻き込むと、画質に影響を与えるため、気泡を巻き込むことなく貼合を行うことが望まれている。 By the way, in the digital signage of the said form, since it influences an image quality when air bubbles are involved in the adhesion layer interface between a window glass and a liquid crystal panel at the time of pasting, it is hoped that it pastes without entraining air bubbles. It is rare.
　特許文献１には、水平状態に保持したタッチパネル（液晶パネルともいう。）の上面に、カバーガラスを貼合する貼合装置が開示されている。 Patent Document 1 discloses a bonding apparatus that bonds a cover glass on the upper surface of a touch panel (also referred to as a liquid crystal panel) held in a horizontal state.
　特許文献１の貼合装置による貼合方法は、まず、水平方向に設置された平面吸着テーブルの上面に液晶パネルを吸着保持するとともに、粘着層を備えたカバーガラスの両端部を保持部によってそれぞれ保持する。次に、双方の保持部の高さを相対的に変えることにより、カバーガラスを片持ち曲げ方式で曲げて保持する。次に、液晶パネルにカバーガラスを貼合すべく、回転ローラを介して一定の圧力をカバーガラスに付与し、カバーガラスの一端を液晶パネルに貼合する。この後、回転ローラの圧力を保持した状態で、回転ローラをカバーガラスの他端に向けて移動しつつ、他端側の保持部を下方に移動してカバーガラスの他端の曲がりを徐々に水平に戻しながら、カバーガラスの全面を液晶パネルに貼合して行く。 In the bonding method using the bonding apparatus of Patent Document 1, first, the liquid crystal panel is sucked and held on the upper surface of the flat suction table installed in the horizontal direction, and both end portions of the cover glass provided with the adhesive layer are respectively held by the holding portions. Hold. Next, the cover glass is bent and held by a cantilever bending method by relatively changing the heights of both holding portions. Next, in order to bond the cover glass to the liquid crystal panel, a certain pressure is applied to the cover glass via a rotating roller, and one end of the cover glass is bonded to the liquid crystal panel. Thereafter, while maintaining the pressure of the rotating roller, while moving the rotating roller toward the other end of the cover glass, the holding portion on the other end side is moved downward to gradually bend the other end of the cover glass. While returning to the horizontal position, the entire surface of the cover glass is bonded to the liquid crystal panel.

　特許文献１の貼合装置は、ガラス製の基板同士を貼合する装置ではあるが、既設の窓ガラスに液晶パネルを、気泡を巻き込むことなく貼合する装置ではない。すなわち、窓ガラスが設置されている施工現場にて、液晶パネルを窓ガラスに貼合する装置ではない。 Although the bonding apparatus of patent document 1 is an apparatus which bonds glass board | substrates, it is not an apparatus which bonds a liquid crystal panel to an existing window glass, without involving a bubble. That is, it is not an apparatus for bonding a liquid crystal panel to a window glass at a construction site where the window glass is installed.
　また、窓ガラスに液晶パネルを貼合する場合、窓ガラスに対する液晶パネルの貼合位置を決める作業は、液晶パネルが大型になるに従って困難になるという問題があった。この問題は、鉛直方向以外の方向（例えば鉛直方向に対して傾斜した傾斜方向、又は水平方向）に設置又は配置されているガラス板に対する液晶パネルの位置決め作業についても同様であった。 Further, when the liquid crystal panel is bonded to the window glass, there is a problem that the operation of determining the bonding position of the liquid crystal panel with respect to the window glass becomes difficult as the liquid crystal panel becomes larger. This problem also applies to the positioning operation of the liquid crystal panel with respect to the glass plate installed or arranged in a direction other than the vertical direction (for example, an inclined direction inclined with respect to the vertical direction or a horizontal direction).
　本発明は、このような事情に鑑みてなされたもので、第１の基板に対する第２の基板の位置決め作業を容易に行うことができる基板の貼合装置及び積層体の製造方法並びに画像表示装置の製造方法を提供することを目的とする。 The present invention has been made in view of such circumstances, and a substrate laminating apparatus, a laminate manufacturing method, and an image display apparatus capable of easily positioning a second substrate with respect to a first substrate.

It is the front view which made the window glass 102 support so that attachment or detachment was possible, (B) is a side view of (A).
　図３（Ａ）、（Ｂ）に示すように、貼合装置１０は、板状部材１２、ハンガーユニット１４（位置調整部材）、ローラ１６（押圧部材）を備えて構成される。貼合装置１０では、任意構成である、ローラ支持部１８、ローラ１６に貼合荷重を付与する伸縮性の貼合荷重調整機構部２０を備えた押圧部２２、および湾曲させる部材であるプッシャー２４Ｂ（図８（Ａ））を備えた形態として説明する。 3 (A) and 3 (B), the bonding apparatus 10 includes a plate-like member 12, a hanger unit 14 (position adjusting member), and a roller 16 (pressing member).

This will be described as a mode provided with (FIG. 8A).
　〈板状部材１２〉
　板状部材１２は、液晶パネル１０６を吸着して保持する部材である。板状部材１２を有すると、後述する湾曲させる部材や押圧部材が液晶パネル１０６に接続または直接押圧されないため、液晶パネルの汚れや破損を防止できる。板状部材１２は、可撓性を有することが好ましい。また、板状部材１２は、液晶パネル１０６の面積より大きいサイズであることが好ましい。これにより貼合終端部まで泡の巻き込みを防止できる。 <Plate-like member 12>
The plate member 12 is a member that sucks and holds the liquid crystal panel 106. When the plate-like member 12 is provided, a member to be bent and a pressing member, which will be described later, are not connected to or directly pressed to the liquid crystal panel 106, so that the liquid crystal panel can be prevented from being stained or damaged. It is preferable that the plate-like member 12 has flexibility. The plate-like member 12 is preferably larger than the area of the liquid crystal panel 106. Thereby, entrainment of a foam can be prevented to the pasting termination part.
　本実施形態においては、板状部材１２は、可撓性板状部材で、液晶パネル１０６よりも大きな面積の例を用いて説明する。さらに、板状部材１２が液晶パネル１０６を吸着保持する例について以下に説明する。 In the present embodiment, the plate-like member 12 is a flexible plate-like member and will be described using an example having a larger area than the liquid crystal panel 106. Further, an example in which the plate-like member 12 holds the liquid crystal panel 106 by suction will be described below.
　図４は、板状部材１２の縦断面図である。 FIG. 4 is a longitudinal sectional view of the plate-like member 12.
　図４の如く、板状部材１２は、矩形状の可撓板２６、可撓板２６の周面部に貼り合わされた額縁状の独立気泡のスポンジ部材２８、及びスポンジ部材２８の内周側の可撓板２６に貼り合わされた矩形状の多孔性シート３０によって構成される。 As shown in FIG. 4, the plate member 12 includes a rectangular flexible plate 26, a frame-shaped closed-cell sponge member 28 bonded to the peripheral surface portion of the flexible plate 26, and the inner peripheral side of the sponge member 28. The rectangular porous sheet 30 is bonded to the flexible plate 26.
　額縁状のスポンジ部材２８と多孔性シート３０との間は額縁状の隙間３２が形成される。スポンジ部材２８及び多孔性シート３０は、可撓板２６に接着剤（又は両面接着テープ）３４を用いて貼り付けられる。 A frame-shaped gap 32 is formed between the frame-shaped sponge member 28 and the porous sheet 30. The sponge member 28 and the porous sheet 30 are attached to the flexible plate 26 using an adhesive (or double-sided adhesive tape) 34.
　可撓板２６の内部には、一端が隙間３２に連通され、他端が複数の吸引ポート３６（図３（Ａ）参照）に連通される吸引路３５が備えられる。吸引ポート３６は、可撓板２６の両端部（すなわち、液晶パネル１０６を吸着しない部分）に複数備えられ、これらの吸引ポート３６は、吸引ホース３８を介して真空ポンプ４０に接続される。 Inside the flexible plate 26, there is provided a suction path 35 having one end communicating with the gap 32 and the other end communicating with a plurality of suction ports 36 (see FIG. 3A). A plurality of suction ports 36 are provided at both ends of the flexible plate 26 (that is, a portion not adsorbing the liquid crystal panel 106), and these suction ports 36 are connected to the vacuum pump 40 via a suction hose 38.
　図４に戻り説明すると、板状部材１２によって液晶パネル１０６を吸着保持する場合には、液晶パネル１０６の周面をスポンジ部材２８に載置して、額縁状の隙間３２の上面を液晶パネル１０６によって閉塞する。この状態で、真空ポンプ４０を駆動すると、吸引ホース３８、吸引ポート３６、吸引路３５、及び隙間３２を介して空気が吸引される。これによって多孔性シート３０の吸着面３０Ａに吸着力が発生するので、吸着面３０Ａに液晶パネル１０６が吸着保持される。 Returning to FIG. 4, when the liquid crystal panel 106 is sucked and held by the plate-like member 12, the peripheral surface of the liquid crystal panel 106 is placed on the sponge member 28, and the upper surface of the frame-like gap 32 is placed on the liquid crystal panel 106. It is blocked by. When the vacuum pump 40 is driven in this state, air is sucked through the suction hose 38, the suction port 36, the suction path 35, and the gap 32. As a result, an adsorption force is generated on the adsorption surface 30A of the porous sheet 30, so that the liquid crystal panel 106 is adsorbed and held on the adsorption surface 30A.
　多孔性シート３０の厚さは、２ｍｍ以下であることが好ましく、１ｍｍ以下（例えば０．５ｍｍ）であることがより好ましい。また、スポンジ部材２８の厚さは、多孔性シート３０の厚さよりも厚くして、液晶パネル１０６を吸着保持した際に弾性変形して多孔性シート３０の厚さまで弾性変形することが好ましい。これにより、隙間３２を確実に閉空間とすることができるので、液晶パネル１０６を吸着保持する吸着力が増大する。 The thickness of the porous sheet 30 is preferably 2 mm or less, and more preferably 1 mm or less (for example, 0.5 mm). The sponge member 28 is preferably thicker than the porous sheet 30 and is elastically deformed to the thickness of the porous sheet 30 when the liquid crystal panel 106 is sucked and held. As a result, the gap 32 can be surely closed, so that the suction force for holding the liquid crystal panel 106 by suction increases.
　多孔性シート３０は、導電性を有することが好ましい。後述する粘着層の面に貼り付けられた剥離シートを剥離する際や、貼合後に可撓性板状部材１２と液晶パネル１０６とを取り外す際等において、静電気の発生を抑えることができる。 The porous sheet 30 preferably has conductivity. Generation of static electricity can be suppressed when a release sheet attached to the surface of the adhesive layer described later is peeled off or when the flexible plate member 12 and the liquid crystal panel 106 are removed after bonding.
　また、可撓板２６は、適度な可撓性が必要であり、例えば厚さが２ｍｍ以上、３ｍｍ以下の塩化ビニル樹脂板が好適である。この場合、一枚の塩化ビニル樹脂板でもよいが、図４のように、厚さが２ｍｍの塩化ビニル樹脂板２６Ａと厚さが０．５ｍｍの塩化ビニル樹脂板２６Ｂとを接着剤（あるいは両面接着テープ）４２で貼り合わせて構成することもできる。可撓板２６の多孔性シート３０を貼り合わせた面の反対側の面に導電性シート（図示しない）を貼り合わせることが好ましい。これにより、貼合時等において、静電気の発生を抑えることができる。 Further, the flexible plate 26 needs to have appropriate flexibility, and for example, a vinyl chloride resin plate having a thickness of 2 mm or more and 3 mm or less is suitable. In this case, a single vinyl chloride resin plate may be used, but as shown in FIG. 4, a vinyl chloride resin plate 26A having a thickness of 2 mm and a vinyl chloride resin plate 26B having a thickness of 0.5 mm are bonded with an adhesive (or on both sides). An adhesive tape) 42 can also be used. It is preferable to bond a conductive sheet (not shown) to the surface opposite to the surface where the porous sheet 30 of the flexible plate 26 is bonded. Thereby, generation | occurrence | production of static electricity can be suppressed at the time of bonding etc.
　〈ハンガーユニット１４：位置調整部材〉
　図３に示すハンガーユニット１４は、液晶パネル１０６を吸着保持した板状部材１２を吊り下げ支持する冶具である。ハンガーユニット１４を設けることで、貼合前に決めた位置に第２の基板をずれることなく貼合を完了できる。ハンガーユニット１４は、窓ガラス１０２の貼合位置に対し所定の貼合隙間を介して、液晶パネル１０６を正対させた状態で、板状部材１２の鉛直方向の位置、傾き、及び水平方向の位置を調整できる冶具であることが好ましい。本実施の形態では、ハンガーユニット１４が、水平方向の位置と鉛直方向の位置及び傾きを調整する冶具として説明する。 <Hanger unit 14: Position adjustment member>
The hanger unit 14 shown in FIG. 3 is a jig that suspends and supports the plate-like member 12 that holds the liquid crystal panel 106 by suction. By providing the hanger unit 14, the bonding can be completed without shifting the second substrate at the position determined before the bonding. The hanger unit 14 has the vertical position, inclination, and horizontal direction of the plate-like member 12 with the liquid crystal panel 106 facing the bonding position of the window glass 102 through a predetermined bonding gap. It is preferable that it is a jig which can adjust a position. In the present embodiment, the hanger unit 14 will be described as a jig that adjusts the position in the horizontal direction and the position and inclination in the vertical direction.
　図３（Ａ）の如く、ハンガーユニット１４は、鉛直方向に配設された窓ガラス１０２の面に沿って、板状部材１２の水平方向の位置を調整する水平方向位置調整部４４、及び窓ガラス１０２の面に沿って、板状部材１２の鉛直方向の位置及び傾きを調整する鉛直方向位置調整部４６を備える。また、ハンガーユニット１４は、一対のハンド吸着盤４８を備えている。これらのハンド吸着盤４８を、窓ガラス１０２に吸着させることにより、ハンガーユニット１４が窓ガラス１０２に着脱自在に支持される。なお、ハンド吸着盤４８に代えて、真空ポンプ（図示せず）に連結した吸着盤も使用可能であるが、現場貼合の場合にはハンドリング性のよいハンド吸着盤４８が好ましい。ハンド吸着盤４８としては、シンワ測定株式会社製の許容荷重が２５ｋｇｆ／１個のものを好適に使用することができる。また、ハンド吸着盤４８の吸着位置は、窓ガラス１０２に限定されるものではなく、窓ガラス１０２を支持する建築物の壁（支持体）に吸着してもよい。 As shown in FIG. 3A, the hanger unit 14 includes a horizontal position adjusting unit 44 that adjusts the horizontal position of the plate member 12 along the surface of the window glass 102 disposed in the vertical direction, and a window. A vertical position adjusting unit 46 that adjusts the vertical position and inclination of the plate-like member 12 is provided along the surface of the glass 102. In addition, the hanger unit 14 includes a pair of hand suction boards 48. By attaching these hand suction boards 48 to the window glass 102, the hanger unit 14 is detachably supported by the window glass 102. In addition, although it replaces with the hand suction board 48, the suction board connected with the vacuum pump (not shown) can also be used, but in the case of on-site bonding, the hand suction board 48 with good handling property is preferable. As the hand suction board 48, one having an allowable load of 25 kgf / 1 manufactured by Shinwa Measurement Co., Ltd. can be suitably used. Further, the suction position of the hand suction board 48 is not limited to the window glass 102 and may be sucked to a wall (support) of a building that supports the window glass 102.
　（水平方向位置調整部４４）
　水平方向位置調整部４４は、レール状部材４４Ａに２台のリニアスライダ４４Ｂ、４４Ｂが、レール状部材４４Ａの長手方向に沿ってスライド自在に支持されることにより構成される。２台のリニアスライダ４４Ｂ、４４Ｂにそれぞれハンド吸着盤４８が設けられる。 (Horizontal position adjustment unit 44)
The horizontal position adjusting unit 44 is configured by supporting two linear sliders 44B and 44B on a rail-like member 44A so as to be slidable along the longitudinal direction of the rail-like member 44A. A hand suction board 48 is provided on each of the two linear sliders 44B and 44B.
　（鉛直方向位置調整部４６）
　鉛直方向位置調整部４６は、一対のターンバックル５０、５０によって構成される。一対のターンバックル５０、５０は、その上端がレール状部材４４Ａの両端部に取り付けられることにより、レール状部材４４Ａに吊設される。 (Vertical direction position adjustment unit 46)
The vertical position adjustment unit 46 includes a pair of turnbuckles 50 and 50. The pair of turnbuckles 50, 50 are suspended from the rail-shaped member 44A by attaching their upper ends to both ends of the rail-shaped member 44A.
　（ハンガーユニット１４の作用）
　ハンガーユニット１４の使用にあたっては、まず、レール状部材４４Ａの長手方向が水平方向を向くように２台のハンド吸着盤４８を窓ガラス１０２の面に吸着させる。ハンド吸着盤４８の吸着位置は、液晶パネル１０６の所望の貼合位置に対応した大まかな位置である。そして、一対のターンバックル５０、５０の下端に設けたフック５０Ａに、板状部材１２の上端に取り付けられたリング１２Ａを着脱自在に係合させる。これにより、液晶パネル１０６を吸着保持した板状部材１２が、ハンガーユニット１４に吊り下げ支持される。そして、レール状部材４４Ａを水平方向に移動させて位置調整するとともに、一対のターンバックル５０、５０を用いての鉛直方向の長さを個別に調整する。ターンバックル５０、５０の長さを同じだけ伸ばすと液晶パネル１０６の位置は鉛直方向に下降し、同じだけ縮めると鉛直方向に上昇し、鉛直方向の位置を調整できる。ターンバックル５０、５０の一方を伸ばし他方を縮めると傾きを調整することができる。これにより、窓ガラス１０２に対する液晶パネル１０６の貼合位置を所望の位置に容易に調整することができる。 (Operation of hanger unit 14)
In using the hanger unit 14, first, the two hand suction boards 48 are attracted to the surface of the window glass 102 so that the longitudinal direction of the rail-shaped member 44 </ b> A faces the horizontal direction. The suction position of the hand suction board 48 is a rough position corresponding to the desired bonding position of the liquid crystal panel 106. Then, the ring 12A attached to the upper end of the plate-like member 12 is detachably engaged with the hook 50A provided at the lower end of the pair of turnbuckles 50, 50. Accordingly, the plate-like member 12 that holds the liquid crystal panel 106 by suction is supported by being hung on the hanger unit 14. Then, the rail-shaped member 44A is moved and adjusted in the horizontal direction, and the vertical length using the pair of turnbuckles 50 and 50 is individually adjusted. When the turnbuckles 50 and 50 are extended by the same length, the position of the liquid crystal panel 106 is lowered in the vertical direction, and when the turnbuckles 50 and 50 are shortened by the same length, the position is raised in the vertical direction. The inclination can be adjusted by extending one of the turnbuckles 50 and 50 and contracting the other. Thereby, the bonding position of the liquid crystal panel 106 with respect to the window glass 102 can be easily adjusted to a desired position.
　なお、水平方向位置調整部４４、及び鉛直方向位置調整部４６の構成は、上記の例に限定されるものではなく、液晶パネル１０６の水平方向の位置及び鉛直方向の位置及び傾きを調整可能な機能を有するものであれば適用できる。 The configurations of the horizontal position adjusting unit 44 and the vertical position adjusting unit 46 are not limited to the above example, and the horizontal position and vertical position and inclination of the liquid crystal panel 106 can be adjusted. Any function can be applied.
　〈ローラ１６：押圧部材〉
　本実施形態の貼合装置１０は、第１の基板と第２の基板との貼合におけるローラ１６（押圧部材）を備えている。ローラ１６は、液晶パネル１０６の幅と同等か、それ以上の軸長を有している。これにより、第２の基板に均一に荷重をかけることができる。ローラ１６は、液晶パネル１０６の上端である貼合開始端から、液晶パネル１０６の下端である貼合終了端へ向けて連続的に移動される。この動作によって、窓ガラス１０２に液晶パネル１０６が貼合される（以下、この工程を貼合工程という。）。なお、前記貼合荷重は、後述する押圧部２２からローラ１６を介して板状部材１２に付与されるものである。 <Roller 16: Pressing member>
The bonding apparatus 10 of this embodiment is provided with the roller 16 (pressing member) in bonding of a 1st board | substrate and a 2nd board | substrate. The roller 16 has an axial length equal to or greater than the width of the liquid crystal panel 106. Thereby, a load can be uniformly applied to the second substrate. The roller 16 is continuously moved from the bonding start end that is the upper end of the liquid crystal panel 106 toward the bonding end end that is the lower end of the liquid crystal panel 106. By this operation, the liquid crystal panel 106 is bonded to the window glass 102 (hereinafter, this process is referred to as a bonding process). In addition, the said bonding load is provided to the plate-shaped member 12 through the roller 16 from the press part 22 mentioned later.
　図５は、ローラ１６によって、液晶パネル１０６が窓ガラス１０２に貼合されている時の貼合荷重分布Ｐを示した説明である。図５の符号５２は、粘着層である。なお、図５は、窓ガラス１０２に粘着層５２を設けた場合であるが、液晶パネル１０６に粘着層５２を設けた場合も同様である。また、図５では、図面の煩雑さを避けるため、板状部材１２の図示を省略している。 FIG. 5 is an explanation showing the bonding load distribution P when the liquid crystal panel 106 is bonded to the window glass 102 by the roller 16. The code | symbol 52 of FIG. 5 is an adhesion layer. FIG. 5 shows the case where the adhesive layer 52 is provided on the window glass 102, but the same applies when the adhesive layer 52 is provided on the liquid crystal panel 106. Further, in FIG. 5, the illustration of the plate-like member 12 is omitted in order to avoid the complexity of the drawing.
　窓ガラス１０２と液晶パネル１０６との間の粘着剤界面に気泡が入り込まないように貼合するためには、貼合荷重分布Ｐの幅Ｗを可能な限り狭くするとともに、分布中央部Ｑの貼合荷重が可能な限り大きくなるようにすることが好ましい。換言すると、ローラ１６がヘルツ接触（線接触）した状態で貼合荷重を液晶パネル１０６に付与することが好ましい。 In order to bond so that air bubbles do not enter the adhesive interface between the window glass 102 and the liquid crystal panel 106, the width W of the bonding load distribution P is reduced as much as possible, and the distribution center portion Q is bonded. It is preferable to make the combined load as large as possible. In other words, it is preferable to apply a bonding load to the liquid crystal panel 106 in a state where the roller 16 is in Hertz contact (line contact).
　このため、ローラ１６は、ローラ表面が硬く且つローラ直径が細い方が貼合荷重を線接触状態で付加させ易くなるので好ましいが、気泡が入り込まないようにするためには、窓ガラス１０２の反りに追従するように、ローラ１６は可撓性を有することが好ましい。この条件を満足するローラ１６としては、例えば外径１０～３０ｍｍ（例えば２０ｍｍ）、肉厚が０．３～３．０ｍｍ（例えば１ｍｍ）のステンレス製又はアルミニウム製の円筒管を好適に使用することができる。この場合、ローラ表面に薄膜状にゴム等の弾性部材を被服させてもよい。 For this reason, it is preferable that the roller 16 has a harder roller surface and a thinner roller diameter because it is easy to apply a bonding load in a line contact state. However, in order to prevent bubbles from entering, the warp of the window glass 102 is preferable. It is preferable that the roller 16 has flexibility so as to follow. As the roller 16 that satisfies this condition, for example, a cylindrical tube made of stainless steel or aluminum having an outer diameter of 10 to 30 mm (for example, 20 mm) and a wall thickness of 0.3 to 3.0 mm (for example, 1 mm) is preferably used. Can do. In this case, an elastic member such as rubber may be coated on the roller surface in a thin film shape.
　また、粘着層５２の層厚が厚く、粘着層５２の弾性率が大きく、かつ粘着層５２が貼合荷重によって弾性変形し易い方が窓ガラス１０２と液晶パネル１０６との間の粘着剤界面に気泡が入り込み難い。このため、粘着層５２の厚さは、０．１～２．０ｍｍ程度に設定され、好ましくは０．２～０．８ｍｍ程度に設定されている。粘着層５２の厚さが０．１ｍｍ以上であれば、外力による衝撃等を粘着層が効果的に緩衝し、画像表示パネルを保護できる。また、窓ガラス１０２と液晶パネル１０６との間に粘着層５２の厚さを超えない異物が混入しても、粘着層５２の厚さが大きく変化することがなく、光透過性能への影響が少ない。粘着層５２の厚さが２．０ｍｍ以下であれば、画像表示装置の厚さが不要に厚くならない。 Further, the adhesive layer 52 is thicker, the elastic modulus of the adhesive layer 52 is larger, and the adhesive layer 52 is more easily elastically deformed by the bonding load. Air bubbles are difficult to enter. For this reason, the thickness of the adhesive layer 52 is set to about 0.1 to 2.0 mm, preferably about 0.2 to 0.8 mm. When the thickness of the adhesive layer 52 is 0.1 mm or more, the adhesive layer effectively buffers an impact caused by an external force, and the image display panel can be protected. In addition, even if foreign matter that does not exceed the thickness of the adhesive layer 52 is mixed between the window glass 102 and the liquid crystal panel 106, the thickness of the adhesive layer 52 does not change greatly, and the light transmission performance is affected. Few. If the thickness of the adhesive layer 52 is 2.0 mm or less, the thickness of the image display device does not become unnecessarily thick.
　また、粘着層５２のせん断弾性率は、１０２～１０５Ｐａの範囲にあることが好ましく、１０３～１０４Ｐａの範囲にあることがより好ましい。 The shear modulus of the adhesive layer 52 is preferably in the range of 10 2 to 10 5 Pa, and more preferably in the range of 10 3 to 10 4 Pa.

The pressing portion 22 is supported movably along the vertical direction with respect to the roller support portion 18.
　車輪ユニット６６には、さらにディスクダンパー（図示しない）を備えることが好ましい。これにより、車輪６６Ａの回転速度を制御でき、貼合中にローラ操作バー６０を離しても押圧部２２が高速で下降することを防止できる。その結果、貼合面に泡が入ることを防止できる。ディスクダンパーには、例えば、不二ラテックス株式会社製ＦＤＮ－４７Ａ－Ｒ（Ｌ）１６３を用いることができる。 It is preferable that the wheel unit 66 further includes a disk damper (not shown). Thereby, the rotational speed of the wheel 66A can be controlled, and the pressing portion 22 can be prevented from descending at high speed even when the roller operation bar 60 is released during bonding. As a result, bubbles can be prevented from entering the bonding surface. As the disk damper, for example, FDN-47A-R (L) 163 manufactured by Fuji Latex Co., Ltd. can be used.
　また、図７に示すように、ローラガイド面５６Ｂの上端（図７の右端）には、傾斜したテーパ形状のスロープ７０が備えられる。また、ローラガイド面５６Ｂには、スロープ７０に連続して窓ガラス１０２に平行な水平面７２が備えられる。スロープ７０を利用して係合部６２の車輪６６Ａを、図７の実線の如く水平面７２に転接させることにより、ローラ１６を貼合開始位置に円滑に位置させることができる。 Further, as shown in FIG. 7, an inclined tapered slope 70 is provided at the upper end (right end in FIG. 7) of the roller guide surface 56B. The roller guide surface 56 </ b> B is provided with a horizontal plane 72 that is continuous with the slope 70 and parallel to the window glass 102. The roller 16 can be smoothly positioned at the bonding start position by rolling the wheel 66A of the engaging portion 62 to the horizontal plane 72 as shown by the solid line in FIG. 7 using the slope 70.
　〈貼合荷重調整機構部２０〉
　図６に示すように、貼合荷重調整機構部２０は、ローラ１６の軸方向の中央位置、両端位置、及び中央位置と両端位置との中間位置の５か所に設けられる。貼合荷重調整機構部２０は、ローラ１６に貼合荷重を付与するとともに外力に応じて伸縮可能に構成される。 <Bonding load adjustment mechanism 20>
As shown in FIG. 6, the bonding load adjusting mechanism 20 is provided at five positions, that is, the center position in the axial direction of the roller 16, both end positions, and an intermediate position between the center position and both end positions. The pasting load adjusting mechanism 20 is configured to apply a pasting load to the roller 16 and to expand and contract according to an external force.
　図７に示すように、貼合荷重調整機構部２０は、一対のスライダ７４、ブラケット７６、スプリング７８、及び一対のバックアップローラ８０から構成される。貼合荷重調整機構部２０は、回転支持ピン等によって首振りが可能となっていることが好ましい。ローラ１６が窓ガラス１０２の反りに追従して変形する際に、一対のバックアップローラ８０をローラ１６に密着させることができ、精度よく窓ガラス１０２の反りに追従することができる。 As shown in FIG. 7, the bonding load adjusting mechanism unit 20 includes a pair of sliders 74, a bracket 76, a spring 78, and a pair of backup rollers 80. It is preferable that the bonding load adjusting mechanism 20 can be swung by a rotation support pin or the like. When the roller 16 deforms following the warp of the window glass 102, the pair of backup rollers 80 can be brought into close contact with the roller 16, and the warp of the window glass 102 can be accurately followed.
　スライダ７４は、ローラ操作バー６０の窓ガラス１０２に対向する面から窓ガラス１０２の面に対して直交方向に突没自在に設けられ、この２本のスライダ７４の先端にブラケット７６が固定される。スプリング７８は、ローラ操作バー６０とブラケット７６との間に介在され、スプリング７８の付勢力によってブラケット７６が窓ガラス１０２に向けて付勢されている。 The slider 74 is provided so as to be able to project and retract in a direction perpendicular to the surface of the window glass 102 from the surface facing the window glass 102 of the roller operation bar 60, and the bracket 76 is fixed to the tips of the two sliders 74. . The spring 78 is interposed between the roller operation bar 60 and the bracket 76, and the bracket 76 is biased toward the window glass 102 by the biasing force of the spring 78.
　一対のバックアップローラ８０は、軸８０Ａを介してブラケット７６に回動自在に支持され、同方向に回転されるローラ１６に転接されてローラ１６の回転を支持する。 The pair of backup rollers 80 is rotatably supported by the bracket 76 via the shaft 80A, and is in rolling contact with the roller 16 rotated in the same direction to support the rotation of the roller 16.
　ローラ１６は、図６の如く、ブラケット６８から突設されたピン８２が内部に挿入されることにより、ローラ操作バー６０からの脱落が防止されている。一対のバックアップローラ８０は、クラウン形状であることが好ましい。クラウン形状のバックアップローラを使用すれば、ローラ１６が窓ガラス１０２の反りにさらに精度よく追従できる。両端に位置する一対のバックアップローラ８０の端は、液晶パネル１０６の端よりはみ出ていることが好ましい。これにより、液晶パネル１０６の端にまで十分な貼合圧力を加えることができる。 As shown in FIG. 6, the roller 16 is prevented from falling off the roller operation bar 60 by inserting a pin 82 protruding from the bracket 68 into the roller 16. The pair of backup rollers 80 are preferably crown-shaped. If a crown-shaped backup roller is used, the roller 16 can follow the warp of the window glass 102 with higher accuracy. The ends of the pair of backup rollers 80 positioned at both ends preferably protrude beyond the ends of the liquid crystal panel 106. Thereby, sufficient bonding pressure can be applied to the end of the liquid crystal panel 106.
　貼合荷重調整機構部２０によれば、図７の二点鎖線で示すように、押圧部２２がローラ操作バー６０のスロープ７０の部分に位置する時には、スプリング７８が伸長した状態でローラ１６が板状部材１２に当接される。この後、図７の実線で示すように、押圧部２２がスロープ７０から水平面７２に移動すると、ローラ１６が板状部材１２を押圧し、その反力によってスプリング７８が収縮し、スプリング７８に付勢力が発生する。この付勢力がローラ１６に付与される貼合荷重となる。 According to the bonding load adjusting mechanism 20, as shown by the two-dot chain line in FIG. 7, when the pressing portion 22 is positioned at the slope 70 portion of the roller operation bar 60, the roller 16 is in a state where the spring 78 is extended. It abuts on the plate member 12. Thereafter, as shown by the solid line in FIG. 7, when the pressing portion 22 moves from the slope 70 to the horizontal plane 72, the roller 16 presses the plate-like member 12, and the spring 78 contracts due to the reaction force, and is attached to the spring 78. Power is generated. This urging force is a bonding load applied to the roller 16.
　〈湾曲させる部材〉
　本実施形態の貼合装置１０は、液晶パネル１０６（第２の基板）および板状部材１２を湾曲させる部材としてプッシャー２４Ｂ（図８（Ａ））を備えている。そのため、液晶パネル１０６と板状部材１２とが上端部から下端部にかけて、窓ガラス１０２から退避する方向に円弧状に湾曲させられ、液晶パネル１０６が窓ガラス１０２に対して凸状に湾曲させられる。これにより、液晶パネル１０６の押圧していない場所と窓ガラス１０２とが接触せず、すなわち、先付けが防止され、その結果、貼合面に気泡が巻き込まれることを防止できる。 <Curved member>
The bonding apparatus 10 of the present embodiment includes a pusher 24B (FIG. 8A) as a member that curves the liquid crystal panel 106 (second substrate) and the plate-like member 12. Therefore, the liquid crystal panel 106 and the plate-like member 12 are curved in an arc shape in the direction of retreating from the window glass 102 from the upper end portion to the lower end portion, and the liquid crystal panel 106 is curved convexly with respect to the window glass 102. . Thereby, the location where the liquid crystal panel 106 is not pressed does not come into contact with the window glass 102, that is, tipping is prevented, and as a result, air bubbles can be prevented from being caught in the bonding surface.
　（湾曲させる部材２４の形態）

The member 24 to be bent in FIG. 8B is a pulling method in which the lower end portion of the plate-like member 12 is pulled by the weight of the weight member 24E in the direction in which it is retracted from the window glass 102. The member 24 to be bent is configured by suspending a weight member 24E from a plate 24A via a pulling rope 24F. Further, in order to apply the weight of the weight member 24E to the plate 24A in the horizontal direction, the tow rope 24F is wound around the pulley 24G.
　板状部材１２に対するプレート２４Ａの固定形態は、特に限定されない。例えば、クランプ方式やハンド吸着盤方式等を採用することにより板状部材１２に対して着脱自在に取り付けることができる。 The fixing form of the plate 24A to the plate member 12 is not particularly limited.

　フレーム１５Ｂおよび保持フレーム１５Ｄ等の形状について、図１６（Ａ）～（Ｃ）にその態様例を示したが、これらに限定されることなく各種の態様が採用可能である。 The material constituting each frame such as the frame 15B can be a metal such as an aluminum alloy, ceramics, or a reinforced plastic such as FRP. In particular, in the case of on-site bonding, from the viewpoint of easy carrying of the reinforcing member 15 and easy attachment to the window glass 102, the material of the frame 15B is particularly preferably an aluminum alloy, FRP or other reinforced plastic that can easily reduce the weight.
Examples of the shapes of the frame 15B, the holding frame 15D, and the like are shown in FIGS. 16A to 16C, but various embodiments can be adopted without being limited thereto.

For example, as shown in FIG. 18, the abutting member 15E is composed of a female screw and a male screw that is screwed to the female screw, and the tip of the male screw protrudes from the female screw to press the back surface of the surface plate 15A. The The contact member 15E is rotated and contacted using torque wrench (not shown) until the torque values become equal to each other. Thus, the entire surface of the surface plate 15A is brought into contact with the non-bonding surface of the window glass 102 with a uniform force. The torque value of the torque wrench at this time is a value obtained by a preliminary test or the like.
　上記した板状部材１２、ハンガーユニット１４（位置調整部材）、ローラ１６（押圧部材）、ローラ支持部１８、貼合荷重調整機構部２０を備えた押圧部２２、及び湾曲させる部材２４は、それぞれ独立したユニットとして構成され、それぞれのユニットは、最大重量が１５ｋｇ以下に構成されている。これにより、各ユニットを容易に取り扱うことができる。したがって、現場貼合する場合には、各ユニットを現場に運び込み、現場で貼合装置１０を容易に組み立てることができる。 The plate-like member 12, the hanger unit 14 (position adjusting member), the roller 16 (pressing member), the roller support portion 18, the pressing portion 22 provided with the bonding load adjusting mechanism portion 20, and the member 24 to be bent are respectively It is configured as an independent unit, and each unit has a maximum weight of 15 kg or less.

As shown in FIG. 11B, the sponge member 84 is compressed to the thickness of the liquid crystal panel 106 by the bonding load by the roller 16 at the time of bonding, so the liquid crystal panel 106 is bonded to the window glass 102 without any problem. Is done.
　スポンジ部材８４は、液晶パネル１０６を囲むように設けてもよく、粘着層５２が窓ガラス１０２に接触するおそれのある液晶パネル１０６の上縁に沿って設けてもよい。 The sponge member 84 may be provided so as to surround the liquid crystal panel 106, and may be provided along the upper edge of the liquid crystal panel 106 in which the adhesive layer 52 may come into contact with the window glass 102.
　図１０（Ｂ）及び図１１に示すように、液晶パネル１０６と同じ厚さのダミーシート８６を設けると、貼合開始位置および貼合終了位置の前後において、可撓性板状部材１２全体の中での剛性の差を解消できるので、貼合開始時の貼合を円滑に実施することができる。図７に示したように、レール５６のスロープ７０を利用してローラ１６を、実線で示す貼合開始位置に装着する場合、貼合開始位置よりも上流側の可撓性板状部材１２にも、可撓性ローラ１６からの貼合荷重が付加される。ダミーシート８６を介在させると、貼合開始位置の前後において、板状部材１２の剛性の差を解消できて、気泡の発生を低減できるため好ましい。 As shown in FIG. 10 (B) and FIG. 11, when a dummy sheet 86 having the same thickness as the liquid crystal panel 106 is provided, the entire flexible plate-like member 12 is placed before and after the bonding start position and the bonding end position. Since the difference in rigidity inside can be eliminated, the bonding at the start of the bonding can be carried out smoothly. As shown in FIG. 7, when the roller 16 is mounted at the bonding start position indicated by the solid line using the slope 70 of the rail 56, the flexible plate-like member 12 on the upstream side of the bonding start position Also, a bonding load from the flexible roller 16 is added. It is preferable to interpose the dummy sheet 86 because the difference in rigidity of the plate-like member 12 can be eliminated before and after the bonding start position, and the generation of bubbles can be reduced.
　図１０（Ｂ）では、ダミーシート８６を貼合開始位置よりも上流側と貼合終了位置の下流側に設けているが、上流側または下流側のいずれか一方だけ設けてもよい。 In FIG. 10B, the dummy sheet 86 is provided on the upstream side and the downstream side of the pasting end position from the pasting start position, but only one of the upstream side or the downstream side may be provided.
　保持工程において、粘着層５２から剥離シートを剥離すると、スポンジ部材８４を設けても、液晶パネル１０６を吸着保持した可撓性板状部材１２を、窓ガラス１０２に対して位置調整する際に、粘着層５２が窓ガラス１０２に接触するおそれがある。この接触を防止する方法としては、粘着層５２が窓ガラス１０２から離れる位置に可撓性板状部材１２を吊り下げることが挙げられる。この場合、貼合時には、ターンバックル５０の下端が窓ガラス１０２へ近づくように移動させた後に貼合工程を行う。 In the holding step, when the release sheet is peeled from the adhesive layer 52, even when the sponge member 84 is provided, when the position of the flexible plate-like member 12 that holds the liquid crystal panel 106 by suction is adjusted with respect to the window glass 102, There is a possibility that the adhesive layer 52 may come into contact with the window glass 102. As a method for preventing this contact, the flexible plate-like member 12 is suspended at a position where the adhesive layer 52 is separated from the window glass 102. In this case, at the time of bonding, the bonding step is performed after the lower end of the turnbuckle 50 is moved so as to approach the window glass 102.
　（位置調整工程）
　次に、図１２（Ａ）、（Ｂ）に示すように、ハンガーユニット１４（位置調整部材）の一対のターンバックル５０のフック５０Ａに、液晶パネル１０６を吸着保持した可撓性板状部材１２のリング１２Ａを着脱自在に係合させ、液晶パネル１０６とともに可撓性板状部材１２を、ハンガーユニット１４を介して窓ガラス１０２に吊り下げ支持する。 (Position adjustment process)
Next, as shown in FIGS. 12A and 12B, the flexible plate-like member 12 in which the liquid crystal panel 106 is sucked and held by the hooks 50A of the pair of turnbuckles 50 of the hanger unit 14 (position adjusting member). The ring 12 </ b> A is detachably engaged, and the flexible plate member 12 is suspended and supported on the window glass 102 via the hanger unit 14 together with the liquid crystal panel 106.
　この後、ハンガーユニット１４によって、可撓性板状部材１２を矢印Ｄで示す鉛直方向及び矢印Ｅで示す水平方向に移動させることによって、窓ガラス１０２の所望の貼合位置に液晶パネル１０６を位置調整する。 Thereafter, the hanger unit 14 moves the flexible plate member 12 in the vertical direction indicated by the arrow D and the horizontal direction indicated by the arrow E, thereby positioning the liquid crystal panel 106 at the desired bonding position of the window glass 102. adjust.
　（配置工程）
　可撓性板状部材１２を湾曲させる部材２４によって湾曲させて液晶パネル１０６を窓ガラス１０２に対して離間させる。なお、位置調整工程では、可撓性板状部材１２が湾曲させられた状態で液晶パネル１０６の貼合位置が調整することが好ましい。 (Arrangement process)
The flexible plate-like member 12 is bent by the member 24 for bending, and the liquid crystal panel 106 is separated from the window glass 102. In the position adjustment step, it is preferable that the bonding position of the liquid crystal panel 106 is adjusted in a state where the flexible plate-like member 12 is curved.
　次に、図１３（Ａ）、（Ｂ）に示すように、吊り下げ支持した可撓性板状部材１２を囲むようにローラ支持部１８を窓ガラス１０２に装着する。すなわち、ローラ支持部１８のレールフレーム５４に設けられた４個のハンド吸着盤４８を窓ガラス１０２に吸着させる。これにより、ローラ支持部１８が窓ガラス１０２に支持される。 Next, as shown in FIGS. 13A and 13B, the roller support portion 18 is mounted on the window glass 102 so as to surround the flexible plate-like member 12 supported by suspension. That is, the four hand suction boards 48 provided on the rail frame 54 of the roller support portion 18 are attracted to the window glass 102. Thereby, the roller support part 18 is supported by the window glass 102.
　次に、図１４（Ａ）、（Ｂ）に示すように、押圧部２２をレール５６のスロープ７０部分からレール５６に装着する。これにより、貼合装置１０が組み立てられ、窓ガラス１０２に液晶パネル１０６を貼合するための準備が完了する。 Next, as shown in FIGS. 14A and 14B, the pressing portion 22 is attached to the rail 56 from the slope 70 portion of the rail 56. Thereby, the bonding apparatus 10 is assembled and the preparation for bonding the liquid crystal panel 106 to the window glass 102 is completed.
　（貼合工程）
　次に、図１５にしたがって、窓ガラス１０２と液晶パネル１０６の貼合手順について説明する。なお、図１５では、図面の煩雑さを避けるため、ローラ支持部１８の図示を省略している。 (Bonding process)
Next, a procedure for bonding the window glass 102 and the liquid crystal panel 106 will be described with reference to FIG. In FIG. 15, the illustration of the roller support portion 18 is omitted to avoid complexity of the drawing.
　図１５（Ａ）～（Ｃ）は、ローラ１６（押圧部材）と押圧部２２とをローラ支持部１８のレール５６に装着する手順を細かく説明したものである。図１５（Ａ）の如く、ローラ１６と押圧部２２は、レール５６の上方から図１５（Ｂ）の如く、レール５６の上端（図７の二点鎖線で示す位置）に装着される。 15 (A) to 15 (C) illustrate in detail the procedure for mounting the roller 16 (pressing member) and the pressing portion 22 on the rail 56 of the roller support portion 18. As shown in FIG. 15A, the roller 16 and the pressing portion 22 are mounted from above the rail 56 to the upper end of the rail 56 (position indicated by a two-dot chain line in FIG. 7) as shown in FIG.
　この状態でローラ操作バー６０を把持し、ローラ操作バー６０を押し下げてローラ１６による貼合を開始する。 In this state, the roller operation bar 60 is gripped, and the roller operation bar 60 is pushed down to start bonding with the roller 16.
　図１５（Ｂ）の位置から、実質的な貼合開始位置である図１５（Ｃ）に示す位置（図７の実線で示す位置）までのローラ１６の移動において、前述したダミーシート８６の作用によって、ローラ１６は、可撓性板状部材１２の全体の中での剛性の差による影響を受けることなく、実質的な貼合開始位置に円滑に移動される。 In the movement of the roller 16 from the position shown in FIG. 15B to the position shown in FIG. 15C (the position shown by the solid line in FIG. 7), which is a substantial bonding start position, the above-described dummy sheet 86 acts. Thus, the roller 16 is smoothly moved to a substantial bonding start position without being affected by the difference in rigidity in the entire flexible plate-like member 12.
　次に、図１５（Ｃ）～（Ｅ）に示すように、ローラ操作バー６０を介してローラ１６を板状部材１２の背面から窓ガラス１０２に向けて押圧して貼合荷重を付与する。これによって、液晶パネル１０６の上端（貼合開始端）を窓ガラス１０２に貼合する。そして、板状部材１２の上端から下端に向けてローラ１６を下降移動させる。これにより、ローラ１６の移動方向に存在する板状部材１２部分の湾曲が、スプリング２４Ｄの付勢力に抗して平坦に矯正されていくので、液晶パネル１０６の貼合面は、上端から下端に向けて窓ガラス１０２に順次貼合されていく。このようなスプリング２４Ｄ及びローラ１６による作用によって、液晶パネル１０６の貼合面は、気泡を巻き込むことなく窓ガラス１０２に貼合される。 Next, as shown in FIGS. 15C to 15E, the roller 16 is pressed from the back surface of the plate-like member 12 toward the window glass 102 via the roller operation bar 60 to apply a bonding load. Thereby, the upper end (bonding start end) of the liquid crystal panel 106 is bonded to the window glass 102. Then, the roller 16 is moved downward from the upper end to the lower end of the plate-like member 12. Accordingly, the curvature of the plate-like member 12 portion existing in the moving direction of the roller 16 is corrected flat against the urging force of the spring 24D, so that the bonding surface of the liquid crystal panel 106 is changed from the upper end to the lower end. It is sequentially pasted to the window glass 102. Due to the action of the spring 24D and the roller 16, the bonding surface of the liquid crystal panel 106 is bonded to the window glass 102 without involving bubbles.
　図１５（Ｅ）に示すように、押圧部２２は、液晶パネル１０６の下方位置に配置されたスポンジ部材８４を超えた位置まで移動され、ここが貼合終了位置となる。この時点で、板状部材１２による液晶パネル１０６の吸着保持を解除する。 As shown in FIG. 15 (E), the pressing portion 22 is moved to a position beyond the sponge member 84 disposed at the lower position of the liquid crystal panel 106, and this is the bonding end position. At this time, the suction holding of the liquid crystal panel 106 by the plate-like member 12 is released.
　なお、上記貼合動作は、貼合開始位置から貼合終了位置までローラ１６を１回移動させる貼合動作であるが、更に貼合終了位置から貼合開始位置までローラ１６を上昇移動させ、上下一往復の貼合動作で貼合を実施してもよい。 In addition, although the said bonding operation | movement is the bonding operation | movement which moves the roller 16 once from the bonding start position to the bonding end position, the roller 16 is further moved up from the bonding end position to the bonding start position, Bonding may be carried out by one round of up and down bonding operation.

Next, the roller support portion 18 is removed from the window glass 102, and the flexible plate member 12 is removed from the hanger unit 14. Finally, the hanger unit 14 is removed from the window glass 102. Thereby, the digital signage (image display apparatus) 100 which is a laminated body in which the liquid crystal panel 106 is bonded to the window glass 102 can be assembled.
