Description

本発明は、曲面基材の保持トレイに関するものである。 The present invention relates to a curved substrate holding tray.

近年、ディスプレイパネルの市場等では、表面が凸状曲面であり裏面が平面である、片側凸ガラスの需要が高まってきており、この片側凸ガラスは、凸状曲面ガラスの裏面（凹状曲面）に平坦に接着剤を塗布し、平面ガラスと貼り合わせることによって製造されている。 In recent years, in the display panel market, etc., there is an increasing demand for single-sided convex glass having a convex curved surface and a flat back surface, and this one-side convex glass is used as the back surface (concave curved surface) of convex curved glass. It is manufactured by applying an adhesive on a flat surface and bonding it to flat glass.

従来、平面ガラスに接着剤のような塗布液を塗布する場合、特許文献１に示されるようなテーブルコーターが用いられている。また、凹状曲面に接着剤のような塗布液を塗布する場合、特許文献２に示されるように、円弧状のノズルを使用して塗布したり、特許文献３に示されるように、凹状曲面の最上位部分に塗布し、塗布液が凹状曲面上を自重で移動するのに任せたりする方法がある。 Conventionally, when a coating solution such as an adhesive is applied to a flat glass, a table coater as shown in Patent Document 1 is used. In addition, when applying a coating liquid such as an adhesive to a concave curved surface, it is applied using an arc-shaped nozzle as shown in Patent Document 2, or a concave curved surface as shown in Patent Document 3. There is a method of applying to the uppermost part and leaving the coating solution to move on its concave curved surface by its own weight.

（全体構成）
図１は、本発明の実施形態に係る塗布装置１０の概略図である。図１に示されるように、塗布装置１０は、塗布液を貯留する貯留タンク１と、塗布液を保持トレイ２上の曲面基材１１に塗布するスリットノズル３と、貯留タンク１からスリットノズル３へ塗布液を供給する供給部４と、塗布装置１０を制御する制御部と、を備えている。スリットノズル３は、ノズル自体に塗布液を吐出するための所定幅のスリットを形成し、スリットノズル３を移動させることによって、基材に塗布液を塗布する、テーブルコーター用のスリットノズルである。(overall structure)
FIG. 1 is a schematic view of a coating apparatus 10 according to an embodiment of the present invention. As shown in FIG. 1, the coating apparatus 10 includes a storage tank 1 that stores the coating liquid, a slit nozzle 3 that applies the coating liquid to the curved substrate 11 on the holding tray 2, and a slit nozzle 3 from the storage tank 1. A supply unit 4 for supplying the coating liquid to the coating unit, and a control unit for controlling the coating apparatus 10. The slit nozzle 3 is a slit nozzle for a table coater in which a slit having a predetermined width for discharging the coating liquid is formed in the nozzle itself, and the slit nozzle 3 is moved to apply the coating liquid to the substrate.

貯留タンク１には、高圧空気が供給されるようになっており、この高圧空気の圧力によって、塗布液を下方から押し出すようになっている。なお、貯留タンク１内の塗布液は、高圧空気を使用せず、重力によっても押し出されることもできる。 The storage tank 1 is supplied with high-pressure air, and the pressure of the high-pressure air pushes the coating liquid from below. The coating liquid in the storage tank 1 can be pushed out by gravity without using high-pressure air.

貯留タンク１は、二方弁１２を介して供給部４に接続されている。供給部４は、モータ４３によって駆動されるシリンジポンプ４４と、三方弁４８と、を備えている。貯留タンク１は、二方弁１２を介して第１供給管路４５に接続され、第１供給管路４５は、三方弁４８を介してシリンジポンプ４４に接続されている。シリンジポンプ４４は、三方弁４８を介して第２供給管路４９に接続されている。第２供給管路４９は、スリットノズル３に接続されている。スリットノズル３は、保持トレイ２に対して水平方向に移動可能となっており、スリットノズル３から塗布された塗布液によって、保持トレイ２上の曲面基材１１に塗膜が形成されるようになっている。なお、制御部は、供給部４を制御することによって、具体的には、モータ４３によって駆動されるシリンジポンプ４４の作動及び三方弁４８の作動を制御することによって、貯留タンク１からスリットノズル３への塗布液の供給圧力及び／又は供給量を制御するようになっている。 The storage tank 1 is connected to the supply unit 4 via a two-way valve 12. The supply unit 4 includes a syringe pump 44 driven by a motor 43 and a three-way valve 48. The storage tank 1 is connected to the first supply line 45 via the two-way valve 12, and the first supply line 45 is connected to the syringe pump 44 via the three-way valve 48. The syringe pump 44 is connected to the second supply pipe line 49 via the three-way valve 48. The second supply conduit 49 is connected to the slit nozzle 3. The slit nozzle 3 is movable in the horizontal direction with respect to the holding tray 2 so that a coating film is formed on the curved substrate 11 on the holding tray 2 by the coating liquid applied from the slit nozzle 3. It has become. The control unit controls the supply unit 4, specifically, the operation of the syringe pump 44 driven by the motor 43 and the operation of the three-way valve 48, thereby controlling the slit nozzle 3 from the storage tank 1. The supply pressure and / or supply amount of the coating liquid is controlled.

図２は、スリットノズル３部分近傍の概略斜視図である。図２に示されるように、スリットノズル３において、塗布液の吐出口であるスリットが、スリットノズル３のノズル移動方向（Ｘ方向）に所定幅だけ形成されており、Ｘ方向に直交するスリット方向Ｙに延びるよう形成されている。そして、スリットノズル３をＸ方向に移動させることによって、保持トレイ２上の曲面基材１１に所定幅で塗布液を塗布するようになっている。制御部は、スリットノズル３のＸ方向の移動速度を調整可能となっている。具体的には、制御部は、スリットノズル３のＸ方向の移動速度を、スリットノズル３のスリット先端部３ａから曲面基材１１の塗布面１１ａまでの距離Ｄに反比例させるよう、スリットノズル３を制御する。 FIG. 2 is a schematic perspective view of the vicinity of the slit nozzle 3 portion. As shown in FIG. 2, in the slit nozzle 3, a slit that is a discharge port for the coating liquid is formed with a predetermined width in the nozzle movement direction (X direction) of the slit nozzle 3, and the slit direction is orthogonal to the X direction. It is formed to extend to Y. Then, by moving the slit nozzle 3 in the X direction, the coating liquid is applied to the curved substrate 11 on the holding tray 2 with a predetermined width. The control unit can adjust the moving speed of the slit nozzle 3 in the X direction. Specifically, the control unit controls the slit nozzle 3 so that the moving speed in the X direction of the slit nozzle 3 is inversely proportional to the distance D from the slit tip 3a of the slit nozzle 3 to the application surface 11a of the curved substrate 11. Control.

曲面基材１１は、Ｙ方向から見て、上面の塗布面１１ａが凹状曲面を有するよう、下方に突出するよう湾曲しており、さらに、凹状曲面は一定の曲率を有している。そして、曲面基材１１は、凹状曲面がＹ方向に延びた構成を有している。 The curved substrate 11 is curved so as to protrude downward so that the upper application surface 11a has a concave curved surface when viewed from the Y direction, and the concave curved surface has a certain curvature. The curved substrate 11 has a configuration in which the concave curved surface extends in the Y direction.

また、曲面基材１１に塗布される塗布液は、チキソ性を備えていることが好ましい。チキソ性とは、ゲルのような塑性固体とゾルのような非ニュートン液体との中間的な物質が示す性質であり、粘度が時間経過と共に変化する性質を意味している。具体的には、剪断応力を受け続けると粘度が次第に低下し液状となり、静止すると粘度が次第に上昇し最終的に固体状となるものを意味する。本実施形態において、塗布液がチキソ性を備えることによって、塗布液は、スリットノズル３から吐出される際は、剪断応力が付加されて液状化し、曲面基材１１に塗布されると、次第に粘度が上昇し最終的に固体状となる。要するに、チキソ性を備える塗布液は、通常は高い粘度であるが、圧力をかけた時は粘度が低下し、流動性がよくなるという液体（身近な例で言えば、ペンキ、ケチャップ、マヨネーズのようなもの）であり、本発明のように、塗膜の厚いところから薄いところへ塗料が流出する恐れがある場合には、圧力をかけて流動性よく吐出を行った後、塗布面に付着した時点では粘度が上昇し、流出しにくいという点で好適な液体である。 Moreover, it is preferable that the coating liquid applied to the curved substrate 11 has thixotropy. The thixotropy is a property exhibited by an intermediate substance between a plastic solid such as a gel and a non-Newtonian liquid such as a sol, and means a property that the viscosity changes with time. Specifically, when the shear stress is continued, the viscosity gradually decreases and becomes liquid, and when it is stationary, the viscosity gradually increases and finally becomes solid. In the present embodiment, when the coating liquid has thixotropy, when the coating liquid is discharged from the slit nozzle 3, it is liquefied by applying a shear stress, and when the coating liquid is applied to the curved substrate 11, the viscosity gradually increases. Rises and finally becomes solid. In short, a coating solution with thixotropy usually has a high viscosity, but when pressure is applied, the viscosity decreases and the fluidity improves (for example, paint, ketchup, mayonnaise) In the case where there is a risk of the paint flowing out from a thick part to a thin part of the coating film as in the present invention, after applying pressure and discharging with good fluidity, it adheres to the coated surface. It is a suitable liquid in that the viscosity increases at the time and hardly flows out.

（保持トレイ）
図３は、保持トレイ２の正面概略図である。図２及び図３に示されるように、曲面基材１１を保持する保持トレイ２は、スリットノズル３のスリット方向（Ｙ方向）の一端部において、スリットノズル３のノズル移動方向（Ｘ方向）における曲面基材１１の両端部で、曲面基材１１を挟むように保持する、一対の挟持部材２１、２２と、Ｘ方向において、一対の挟持部材２１、２２間に配置され、曲面基材１１を下方より支持する、支持部材２３、２４と、を備えている。さらに、保持トレイ２は、スリットノズル３のスリット方向（Ｙ方向）の他端部において、スリットノズル３のノズル移動方向（Ｘ方向）における曲面基材１１の両端部で、曲面基材１１を挟むように保持する、一対の挟持部材２５、２６と、Ｘ方向において、一対の挟持部材２５、２６間に配置され、曲面基材１１を下方より支持する、支持部材２７、２８と、を備えている。そして、挟持部材２１と支持部材２３、及び、挟持部材２５と支持部材２７は、スリットノズル３のスリット方向（Ｙ方向）における曲面基材１１の両端部で、一対として設けられており、挟持部材２２と支持部材２４、及び、挟持部材２６と支持部材２８は、スリットノズル３のスリット方向（Ｙ方向）における曲面基材１１の両端部で、一対として設けられている。(Holding tray)
FIG. 3 is a schematic front view of the holding tray 2. As shown in FIG. 2 and FIG. 3, the holding tray 2 that holds the curved substrate 11 is located at one end in the slit direction (Y direction) of the slit nozzle 3 in the nozzle movement direction (X direction) of the slit nozzle 3. The curved base material 11 is disposed between the pair of sandwiching members 21 and 22 in the X direction and is held between the pair of sandwiching members 21 and 22 to hold the curved base material 11 at both ends thereof. Support members 23 and 24 supported from below. Further, the holding tray 2 sandwiches the curved substrate 11 at both ends of the curved substrate 11 in the nozzle movement direction (X direction) of the slit nozzle 3 at the other end of the slit nozzle 3 in the slit direction (Y direction). A pair of sandwiching members 25 and 26, and support members 27 and 28 that are disposed between the pair of sandwiching members 25 and 26 in the X direction and support the curved substrate 11 from below. Yes. The sandwiching member 21 and the support member 23, and the sandwiching member 25 and the support member 27 are provided as a pair at both ends of the curved substrate 11 in the slit direction (Y direction) of the slit nozzle 3. 22 and the support member 24, and the sandwiching member 26 and the support member 28 are provided as a pair at both ends of the curved substrate 11 in the slit direction (Y direction) of the slit nozzle 3.

挟持部材２１は、上下方向に延びる鉛直部分２１ａと、鉛直部分２１ａの上端部から水平方向に延びる水平部分２１ｂと、を備えている。ここで、図３において、鉛直部分２１ａの長さＡ、スリットノズル３と鉛直部分２１ａとの鉛直方向長さＢ、及び、スリットノズル３（初期位置）と鉛直部分２１ａとのＸ方向長さＣは一定である。したがって、挟持部材２１で曲面基材１１を挟持すると、曲面基材１１の厚さや曲率が変化しても、長さＡ、長さＢ及び長さＣが一定であるので、曲面基材１１の曲率が変わっても、塗布装置１０の作動の初期条件を一定とすることができる。なお、挟持部材２１、２２、２５、２６は、曲面基材１１の両端部を同じ高さで挟持するように、水平部分の下端の高さ、すなわち鉛直部分の長さＡが同じとなるように形成されている。 The clamping member 21 includes a vertical portion 21a extending in the vertical direction and a horizontal portion 21b extending in the horizontal direction from the upper end portion of the vertical portion 21a. Here, in FIG. 3, the length A of the vertical portion 21a, the vertical length B of the slit nozzle 3 and the vertical portion 21a, and the X-direction length C of the slit nozzle 3 (initial position) and the vertical portion 21a. Is constant. Therefore, when the curved base material 11 is sandwiched by the sandwiching member 21, the length A, the length B, and the length C are constant even if the thickness and curvature of the curved base material 11 change. Even if the curvature changes, the initial condition of the operation of the coating apparatus 10 can be made constant. Note that the holding members 21, 22, 25, and 26 have the same height at the lower end of the horizontal portion, that is, the length A of the vertical portion, so that both ends of the curved substrate 11 are held at the same height. Is formed.

図４は、挟持部材２１の拡大斜視図である。挟持部材２２、２５、２６は、挟持部材２１と同様の構造を備えており、以下、挟持部材２１を例として説明する。図４に示されるように、挟持部材２１の水平部分２１ｂは、上端部２１ｂ１に対して、下端部２１ｂ２の水平断面が小さくなるように形成されている。 FIG. 4 is an enlarged perspective view of the clamping member 21. The sandwiching members 22, 25, and 26 have the same structure as the sandwiching member 21, and the sandwiching member 21 will be described below as an example. As shown in FIG. 4, the horizontal portion 21b of the clamping member 21 is formed so that the horizontal section of the lower end portion 21b2 is smaller than the upper end portion 21b1.

挟持部材２２は、ノズル移動方向（Ｘ方向）における曲面基材１１の長さに合わせて、挟持部材２１、２２間の距離を調整することができるよう、挟持部材２１に対して、Ｘ方向に沿って移動可能となっている。具体的には、挟持部材２２と係合するボールネジ２０１が、テーブル２０のＸ方向端部からＸ方向内側に延びるよう設けられており、ボールネジ２０１の先端部のハンドル２０２を回転させることによって、ボールネジ２０１に係合した挟持部材２２がＸ方向に移動可能となる。さらに、挟持部材２２及び支持部材２４は、テーブル２０の上部に取り付けられＸ方向に移動可能な移動台２０３に取り付けられているので、ボールネジ２０１によって挟持部材２２がＸ方向に移動すると、移動台２０３もＸ方向に移動し、さらに、支持部材２４もＸ方向に移動する。その結果、挟持部材２２と支持部材２４とは一体としてＸ方向に移動するようになっている。 The clamping member 22 is arranged in the X direction with respect to the clamping member 21 so that the distance between the clamping members 21 and 22 can be adjusted according to the length of the curved substrate 11 in the nozzle movement direction (X direction). It can move along. Specifically, a ball screw 201 that engages with the clamping member 22 is provided so as to extend inward in the X direction from the X direction end of the table 20, and by rotating the handle 202 at the tip end of the ball screw 201, The clamping member 22 engaged with 201 can move in the X direction. Further, since the holding member 22 and the support member 24 are attached to the upper part of the table 20 and attached to the movable table 203 that can move in the X direction, when the holding member 22 moves in the X direction by the ball screw 201, the movable table 203. Also moves in the X direction, and the support member 24 also moves in the X direction. As a result, the clamping member 22 and the support member 24 move in the X direction as a unit.

挟持部材２２と同様に、挟持部材２６は、ノズル移動方向（Ｘ方向）における曲面基材１１の長さに合わせて、挟持部材２５、２６間の距離を調整することができるよう、挟持部材２５に対して、Ｘ方向に沿って移動可能となっている。そして、支持部材２８は、挟持部材２６と一体としてＸ方向に移動するようになっている。 Similar to the sandwiching member 22, the sandwiching member 25 can adjust the distance between the sandwiching members 25, 26 according to the length of the curved substrate 11 in the nozzle movement direction (X direction). On the other hand, it is movable along the X direction. The support member 28 moves in the X direction as a unit with the clamping member 26.

支持部材２３、２４、２７、２８は、同様の構造を備えている。以下、支持部材２３を例として説明する。支持部材２３は、上端部に曲面基材１１と接触する支持部２３ａを備えており、支持部２３ａは、圧縮空気、電磁力、又は機械的な構造等によって、上下方向に昇降可能となっている。支持部２３ａの頂部は、球形状を有しており、樹脂でできている。さらに、支持部材２３は、上下方向に付勢される、付勢部材２３ｂを備えている。付勢部材２３ｂは、例えばバネであり、曲面基材１１を支持する上での緩衝機能を備えている。付勢部材２３ｂは管状部材２３ｃに収容されており、支持部２３ａが上下に昇降するようになっている。 The support members 23, 24, 27, and 28 have the same structure. Hereinafter, the support member 23 will be described as an example. The support member 23 includes a support portion 23a that comes into contact with the curved base material 11 at the upper end, and the support portion 23a can be moved up and down by compressed air, electromagnetic force, mechanical structure, or the like. Yes. The top part of the support part 23a has a spherical shape and is made of resin. Further, the support member 23 includes a biasing member 23b that is biased in the vertical direction. The urging member 23b is, for example, a spring and has a buffering function for supporting the curved substrate 11. The urging member 23b is accommodated in the tubular member 23c, and the support portion 23a moves up and down.

（保持トレイへの曲面基材の取り付け）
図５〜図７は、保持トレイ２への曲面基材１１の取り付け作業を説明する図である。まず、図５に示されるように、挟持部材２２及び支持部材２４を、移動台２０３をテーブル２０に対して移動させることによって、挟持部材２１及び支持部材２３からＸ方向に最も離れた位置まで移動させる。(Attaching the curved base material to the holding tray)
5-7 is a figure explaining the attachment operation | work of the curved base material 11 to the holding tray 2. FIG. First, as shown in FIG. 5, the clamping member 22 and the supporting member 24 are moved to the position farthest in the X direction from the clamping member 21 and the supporting member 23 by moving the movable table 203 with respect to the table 20. Let

次に、図６に示されるように、曲面基材１１の一端部を挟持部材２１によって挟持させ、さらに、支持部材２３の支持部２３ａで上下方向に緩衝させながら、曲面基材１１を支持部材２３によって下方より支持させる。 Next, as shown in FIG. 6, one end of the curved base material 11 is sandwiched by the sandwiching member 21, and further, the curved base material 11 is supported by the support member 23 a while being vertically buffered by the support portion 23 a of the support member 23. 23 is supported from below.

最後に、図７に示されるように、挟持部材２２及び支持部材２４を、移動台２０３をテーブル２０に対して移動させることによって、挟持部材２１及び支持部材２３の方に接近させる。そして、曲面基材１１の他端部を挟持部材２２によって挟持させ、さらに、支持部材２４の支持部２３ａで上下方向に緩衝させながら、曲面基材１１を支持部材２４によって下方より支持させる。なお、上記取り付けにおける、挟持部材２５及び支持部材２７の作動は、挟持部材２１及び支持部材２３の作動に対応し、挟持部材２６及び支持部材２８の作動は、挟持部材２２及び支持部材２４の作動に対応する。 Finally, as shown in FIG. 7, the sandwiching member 22 and the support member 24 are moved closer to the sandwiching member 21 and the support member 23 by moving the movable table 203 relative to the table 20. Then, the curved base 11 is supported from below by the support member 24 while the other end of the curved base 11 is sandwiched by the sandwiching member 22 and further buffered in the vertical direction by the support 23 a of the support member 24. The operation of the clamping member 25 and the support member 27 in the attachment corresponds to the operation of the clamping member 21 and the support member 23, and the operation of the clamping member 26 and the support member 28 is the operation of the clamping member 22 and the support member 24. Corresponding to

塗布装置１０は、次のように作動するようになっている。 The coating device 10 operates as follows.

まず、貯留タンク１に高圧空気を供給して加圧し、二方弁１２を開放する。そして、三方弁４８を吸引側とし、モータ４３を吸引側に回転させると、貯留タンク１内の塗布液が、第１供給管路４５を通り、三方弁４８を介してシリンジポンプ４４に充填される。 First, high pressure air is supplied to the storage tank 1 to pressurize it, and the two-way valve 12 is opened. When the three-way valve 48 is set to the suction side and the motor 43 is rotated to the suction side, the coating liquid in the storage tank 1 passes through the first supply pipe 45 and is filled into the syringe pump 44 via the three-way valve 48. The

シリンジポンプ４４への充填が完了すると、三方弁４８を吐出側に切り替える。そして、モータ４３を吐出側に回転させると、シリンジポンプ４４内の塗布液が、三方弁４８から第２供給管路４９を通り、スリットノズル３に供給される。制御部は、シリンジポンプ４４内の塗布液をスリットノズル３に供給する際、塗布液の供給圧力又は供給量を一定となるよう、モータ４３を制御する。そして、塗布液は、スリットノズル３の吐出口３ｂから、保持トレイ２上の曲面基材１１に供給圧力又は供給量が一定となるよう吐出され、塗膜となる。 When the filling of the syringe pump 44 is completed, the three-way valve 48 is switched to the discharge side. When the motor 43 is rotated to the discharge side, the coating liquid in the syringe pump 44 is supplied from the three-way valve 48 to the slit nozzle 3 through the second supply conduit 49. When supplying the application liquid in the syringe pump 44 to the slit nozzle 3, the control unit controls the motor 43 so that the supply pressure or supply amount of the application liquid is constant. Then, the coating liquid is discharged from the discharge port 3b of the slit nozzle 3 to the curved substrate 11 on the holding tray 2 so that the supply pressure or supply amount is constant, and becomes a coating film.

前記構成の塗布装置１０によれば、次のような効果を発揮できる。 According to the coating apparatus 10 having the above-described configuration, the following effects can be exhibited.

（１）保持トレイ２は、挟持部材２１、２２及び２５、２６で曲面基材１１のＸ方向両端部を挟むように保持し、挟持部材２１、２２及び２５、２６間に配置された支持部材２３、２４及び２７、２８で曲面基材１１を下方より支持するので、基材が曲面でも保持でき、また、Ｒ形状の異なる曲面基材１１を保持できる。 (1) The holding tray 2 holds the holding members 21, 22, 25, and 26 so as to hold both ends in the X direction of the curved substrate 11, and is a support member disposed between the holding members 21, 22, 25, and 26. Since the curved base material 11 is supported from below by 23, 24 and 27, 28, the base material can be held even on a curved surface, and the curved base material 11 having a different R shape can be held.

（２）挟持部材２１、２５及び支持部材２３、２７、及び、挟持部材２２、２６及び支持部材２４、２８がＹ方向における曲面基材１１の両端部に一対として設けられているので、最小限の挟持部材及び支持部材で保持トレイを構成することができる。 (2) Since the sandwiching members 21 and 25 and the support members 23 and 27 and the sandwiching members 22 and 26 and the support members 24 and 28 are provided as a pair at both ends of the curved substrate 11 in the Y direction, the minimum A holding tray can be constituted by the sandwiching member and the supporting member.

（３）支持部材２３、２４、２７、２８の支持部は、上下方向に昇降可能となっているので、曲面基材１１のＲ形状に合わせて、支持部材２３、２４、２７、２８の支持部の上下方向位置を調整することができる。 (3) Since the support portions of the support members 23, 24, 27, and 28 can be moved up and down, the support members 23, 24, 27, and 28 are supported in accordance with the R shape of the curved substrate 11. The vertical position of the part can be adjusted.

（４）挟持部材２２、２６は、Ｘ方向に沿って移動可能となっているので、曲面基材１１を保持する際に、曲面基材１１の幅よりも挟持部材２２、２６を拡げた状態から、曲面基材１１の両端部を挟むことができるので、曲面基材１１を保持しやすい。また、Ｘ方向における曲面基材１１の長さに合わせて、挟持部材２１、２２及び２５、２６間の距離を調整することができる。 (4) Since the holding members 22 and 26 are movable along the X direction, the holding members 22 and 26 are wider than the width of the curved base material 11 when the curved base material 11 is held. Since both ends of the curved base material 11 can be sandwiched, the curved base material 11 can be easily held. Moreover, according to the length of the curved base material 11 in the X direction, the distance between the holding members 21, 22 and 25, 26 can be adjusted.

（５）挟持部材２１、２２、２５、２６の水平部分は、上端部に対して下端部の水平断面が小さくなるように形成されているので、曲面基材１１と挟持部材２１、２２、２５、２６との接触面積を低減することができる。その結果、挟持部材２１、２２、２５、２６の接触による曲面基材１１への損傷の可能性を低減することができる。 (5) Since the horizontal portions of the sandwiching members 21, 22, 25, and 26 are formed so that the horizontal cross section of the lower end portion is smaller than the upper end portion, the curved base 11 and the sandwiching members 21, 22, and 25 are formed. , 26 can be reduced. As a result, it is possible to reduce the possibility of damage to the curved base material 11 due to the contact of the sandwiching members 21, 22, 25, and 26.

（６）挟持部材２１、２２、２５、２６は、曲面基材１１の両端部を同じ高さで挟持するようになっているので、挟持位置において、スリット先端部３ａから曲面基材１１の塗布面１１ａまでの距離Ｄが規定される。その結果、曲面基材１１のＲ形状が変わってもスリットノズル３の動作する初期位置を同じとすることができ、スリットノズル３の動作制御を容易とすることができる。 (6) Since the clamping members 21, 22, 25, and 26 are configured to clamp both ends of the curved base material 11 at the same height, the curved base material 11 is applied from the slit tip 3a at the clamping position. A distance D to the surface 11a is defined. As a result, even if the R shape of the curved substrate 11 changes, the initial position at which the slit nozzle 3 operates can be made the same, and the operation control of the slit nozzle 3 can be facilitated.

（７）支持部材２３、２４、２７、２８は、上下方向に付勢される付勢部材を備えているので、その緩衝性によって支持部材に曲面基材１１が載った際に無理な力がかからず、曲面基材１１の損傷を防止し、さらに、曲面基材１１の形状の誤差に対応することができ、支持部材２３、２４、２７、２８の支持性を向上させることができる。 (7) Since the support members 23, 24, 27, and 28 are provided with urging members that are urged in the vertical direction, an unreasonable force is exerted when the curved substrate 11 is placed on the support member due to its buffering properties. Therefore, damage to the curved substrate 11 can be prevented, and an error in the shape of the curved substrate 11 can be dealt with, and the supportability of the support members 23, 24, 27, and 28 can be improved.

（８）支持部材２４は、挟持部材２２とＸ方向に沿って一体として移動し、支持部材２８は、挟持部材２６とＸ方向に沿って一体として移動するようになっているので、挟持部材２２及び支持部材２４との位置関係を維持したまま、Ｘ方向に移動させることができ、また、挟持部材２６及び支持部材２８との位置関係を維持したまま、Ｘ方向に移動させることができる。したがって、曲面基材１１の保持のための挟持部材２２及び支持部材２４、挟持部材２６及び支持部材２８の位置調整を容易に行うことができる。 (8) The support member 24 moves integrally with the clamping member 22 along the X direction, and the support member 28 moves integrally with the clamping member 26 along the X direction. In addition, it can be moved in the X direction while maintaining the positional relationship with the support member 24, and can be moved in the X direction while maintaining the positional relationship with the sandwiching member 26 and the support member 28. Therefore, it is possible to easily adjust the positions of the holding member 22 and the supporting member 24 for holding the curved substrate 11, the holding member 26 and the supporting member 28.

（９）支持部材２３、２４、２７、２８の上端部は、球形状を有しているので、曲面基材１１と支持部材２３、２４、２７、２８との接触面積を低減することができる。その結果、支持部材２３、２４、２７、２８の接触による曲面基材１１への損傷の可能性を低減することができる。また、支持部材２３、２４、２７、２８の上端部は、樹脂でできているので、支持部材２３、２４、２７、２８の接触による曲面基材１１への損傷の可能性を低減することができる。 (9) Since the upper ends of the support members 23, 24, 27, and 28 have a spherical shape, the contact area between the curved substrate 11 and the support members 23, 24, 27, and 28 can be reduced. . As a result, the possibility of damage to the curved substrate 11 due to the contact of the support members 23, 24, 27, and 28 can be reduced. In addition, since the upper ends of the support members 23, 24, 27, and 28 are made of resin, the possibility of damage to the curved substrate 11 due to the contact of the support members 23, 24, 27, and 28 can be reduced. it can.

（１０）スリットノズル３の初期位置側である挟持部材２１、２５が固定され、挟持部材２２、２６がＸ方向に移動して曲面基材１１を挟持するようになっているので、スリットノズル３の初期位置及び挟持部材２１、２５による曲面基材１１の挟持位置が固定される。その結果、塗布装置１０の作動の初期条件を一定とすることができ、スリットノズル３の動作制御を容易とすることができる。 (10) The clamping members 21 and 25 on the initial position side of the slit nozzle 3 are fixed, and the clamping members 22 and 26 move in the X direction so as to clamp the curved substrate 11. The initial position and the clamping position of the curved substrate 11 by the clamping members 21 and 25 are fixed. As a result, the initial condition of the operation of the coating apparatus 10 can be made constant, and the operation control of the slit nozzle 3 can be facilitated.

（１１）スリットノズル３への塗布液の供給圧力を一定にした状態で、スリットノズル３の移動速度を、スリット先端部３ａから曲面基材１１の塗布面１１ａまでの距離Ｄに反比例させるようにスリットノズル３を移動させることによって、曲面基材１１に対して、塗布液の上面が平面となるよう塗布液を塗布することができる。 (11) In a state where the supply pressure of the coating liquid to the slit nozzle 3 is constant, the moving speed of the slit nozzle 3 is made inversely proportional to the distance D from the slit tip 3a to the coating surface 11a of the curved substrate 11. By moving the slit nozzle 3, the coating liquid can be applied to the curved substrate 11 so that the upper surface of the coating liquid is flat.

（１２）スリットノズル３への塗布液の供給量を一定にした状態で、スリットノズル３の移動速度を、スリット先端部３ａから曲面基材１１の塗布面１１ａまでの距離Ｄに反比例させるようにスリットノズル３を移動させることによって、曲面基材１１に対して、塗布液の上面が平面となるよう塗布液を塗布することができる。 (12) In a state where the supply amount of the coating liquid to the slit nozzle 3 is constant, the moving speed of the slit nozzle 3 is inversely proportional to the distance D from the slit tip 3a to the coating surface 11a of the curved substrate 11. By moving the slit nozzle 3, the coating liquid can be applied to the curved substrate 11 so that the upper surface of the coating liquid is flat.

（１３）曲面基材１１の凹状曲面に塗布液として接着剤を塗布することによって、凹状曲面において接着剤の上面が平面となるよう接着剤を塗布することができる。その結果、凸状曲面ガラスと平面ガラスとの貼り合わせが容易となり、片側凸ガラスを容易に形成することができる。 (13) By applying an adhesive as a coating liquid to the concave curved surface of the curved substrate 11, the adhesive can be applied so that the upper surface of the adhesive is flat on the concave curved surface. As a result, it becomes easy to bond the convex curved glass and the flat glass, and the one-side convex glass can be easily formed.

（１４）塗布液がチキソ性を有していると、曲面基材１１に塗布された塗布液の移動を抑制することができ、曲面基材１１の所定の領域内に塗布液を平坦に塗布することができる。また、塗布液がチキソ性を有していると、吐出後の塗布液は粘度が高くなるため、曲面基材１１に平面塗布する場合のように、塗布中に塗布する厚みが変化する場合であっても、厚みの厚いところから薄いところへ塗布液が流れて厚みが変化するということが発生しにくく、塗布液の上面を適切な平面に仕上げることができる。 (14) When the coating liquid has thixotropy, the movement of the coating liquid applied to the curved base material 11 can be suppressed, and the coating liquid is applied flatly within a predetermined region of the curved base material 11. can do. In addition, when the coating solution has thixotropy, the viscosity of the coating solution after ejection becomes high, and thus when the coating thickness changes during coating as in the case of planar coating on the curved substrate 11. Even if it exists, it is hard to generate | occur | produce that a coating liquid flows from a thick place to a thin place, and thickness does not generate | occur | produce, and the upper surface of a coating liquid can be finished in a suitable plane.

上記実施形態では、支持部材はノズル移動方向（Ｘ方向）に２つ設けられているが、１つ又は３以上設けられても良い。 In the above embodiment, two support members are provided in the nozzle movement direction (X direction), but one or three or more support members may be provided.

上記実施形態では、挟持部材と支持部材は、スリットノズル３のスリット方向（Ｙ方向）における曲面基材１１の両端部で、一対として設けられているが、挟持部材と支持部材は、Ｙ方向において、所定間隔を有して、３以上設けられていても良い。 In the above embodiment, the sandwiching member and the support member are provided as a pair at both ends of the curved substrate 11 in the slit direction (Y direction) of the slit nozzle 3, but the sandwiching member and the support member are in the Y direction. Three or more may be provided with a predetermined interval.

本構成によれば、挟持部材及び支持部材がスリット方向において所定間隔をおいて複数設けられているので、合理的な数の挟持部材及び支持部材で保持トレイを構成することができる。 According to this configuration, since a plurality of clamping members and support members are provided at predetermined intervals in the slit direction, a holding tray can be configured with a reasonable number of clamping members and support members.

上記実施形態では、挟持部材２２、２６が、挟持部材２１、２５に対して、Ｘ方向に沿って移動可能となっている。しかし、挟持部材２１、２５が、挟持部材２２、２６に対して、Ｘ方向に沿って移動可能となっていても良い。また、挟持部材２１、２２は、挟持部材２１、２２間の中間線の位置が維持されるよう、Ｘ方向に沿って一体として移動し、挟持部材２５、２６は、挟持部材２５、２６間の中間線の位置が維持されるよう、Ｘ方向に沿って一体として移動するようになっていても良い。これは、挟持部材２１、２２の場合、移動台２０３、２０４が、挟持部材２１、２２間の中間線の位置が維持されるように、テーブル２０に対して移動することによって達成される。これにより、曲面基材１１の寸法が異なっても、常に保持トレイ２の中央で曲面基材１１を保持できる。 In the above embodiment, the holding members 22 and 26 are movable along the X direction with respect to the holding members 21 and 25. However, the clamping members 21 and 25 may be movable along the X direction with respect to the clamping members 22 and 26. Further, the clamping members 21 and 22 move as a unit along the X direction so that the position of the intermediate line between the clamping members 21 and 22 is maintained, and the clamping members 25 and 26 are between the clamping members 25 and 26. It may be configured to move integrally along the X direction so that the position of the intermediate line is maintained. In the case of the clamping members 21 and 22, this is achieved by moving the moving bases 203 and 204 with respect to the table 20 so that the position of the intermediate line between the clamping members 21 and 22 is maintained. Thereby, even if the dimensions of the curved substrate 11 are different, the curved substrate 11 can always be held at the center of the holding tray 2.

図８〜図１０は、挟持部材２１、２２は、挟持部材２１、２２間の中間線Ｌの位置が維持されるよう、Ｘ方向に沿って一体として移動し、挟持部材２５、２６は、挟持部材２５、２６間の中間線Ｌの位置が維持されるよう、Ｘ方向に沿って一体として移動する場合の、保持トレイ２への曲面基材１１の上記実施形態とは異なる取り付け作業を説明する図である。挟持部材２１、２２間の中間線Ｌの位置が維持されるよう、Ｘ方向に沿って一体として移動するとは、例えば、挟持部材２１を挟持部材２２から離れる方向に移動させると、挟持部材２２も同じ距離だけ挟持部材２１から離れる方向に移動し、挟持部材２１を挟持部材２２に接近する方向に移動させると、挟持部材２２も同じ距離だけ挟持部材２１に接近する方向に移動することを意味する。挟持部材２５、２６間の中間線Ｌの位置が維持されるよう、Ｘ方向に沿って一体として移動するというのも上記と同じ意味である。なお、管状部材２３ｃ、２４ｃは、底部２３ｄ、２４ｄを有しており、底部２３ｄ、２４ｄは、穴部２３ｅ、２４ｅに対して上下方向に沿って移動可能となっている。 In FIGS. 8 to 10, the clamping members 21 and 22 move as a unit along the X direction so that the position of the intermediate line L between the clamping members 21 and 22 is maintained, and the clamping members 25 and 26 are clamped. An attachment operation different from the above embodiment of the curved substrate 11 to the holding tray 2 when moving as a unit along the X direction so that the position of the intermediate line L between the members 25 and 26 is maintained will be described. FIG. To move integrally along the X direction so that the position of the intermediate line L between the sandwiching members 21 and 22 is maintained, for example, when the sandwiching member 21 is moved away from the sandwiching member 22, the sandwiching member 22 is also moved. When moving in the direction away from the clamping member 21 by the same distance and moving the clamping member 21 in the direction approaching the clamping member 22, it means that the clamping member 22 also moves in the direction approaching the clamping member 21 by the same distance. . The same meaning as described above also means that the intermediate line L is moved along the X direction so that the position of the intermediate line L between the holding members 25 and 26 is maintained. The tubular members 23c and 24c have bottom portions 23d and 24d, and the bottom portions 23d and 24d are movable in the vertical direction with respect to the hole portions 23e and 24e.

保持トレイ２への曲面基材１１の取り付け作業では、まず、図８に示されるように、挟持部材２１及び支持部材２３と、挟持部材２２及び支持部材２４とを、移動台２０３、２０４をテーブル２０に対して移動させることによって、互いにＸ方向に最も離れた位置まで移動させる。 In the work of attaching the curved substrate 11 to the holding tray 2, first, as shown in FIG. 8, the sandwiching member 21 and the support member 23, the sandwiching member 22 and the support member 24, and the movable bases 203 and 204 on the table. By moving with respect to 20, they are moved to positions farthest from each other in the X direction.

次に、図９に示されるように、ロボットハンド２０９等で、曲面基材１１を挟持部材２１と挟持部材２２との間に位置させる。 Next, as shown in FIG. 9, the curved substrate 11 is positioned between the sandwiching member 21 and the sandwiching member 22 with the robot hand 209 or the like.

最後に、図１０に示されるように、挟持部材２１及び支持部材２３と、挟持部材２２及び支持部材２４とを、移動台２０３、２０４をテーブル２０に対して移動させることによって、互いにＸ方向に接近させる。そして、曲面基材１１の一端部を挟持部材２１によって挟持させ、さらに、底部２３ｄの下方から圧縮空気等により管状部材２３ｃを、穴部２３ｅから上方に持ち上げ、支持部材２３の支持部を上方に昇降させて、曲面基材１１を支持部材２３によって下方より支持させる。同時に、曲面基材１１の他端部を挟持部材２２によって挟持させ、さらに、底部２４ｄの下方から圧縮空気等により管状部材２４ｃを、穴部２４ｅから上方に持ち上げ、支持部材２４の支持部を上方に昇降させて、曲面基材１１を支持部材２４によって下方より支持させる。なお、上記取り付けにおける、挟持部材２５及び支持部材２７の作動は、挟持部材２１及び支持部材２３の作動に対応し、挟持部材２６及び支持部材２８の作動は、挟持部材２２及び支持部材２４の作動に対応する。これら一連の動作により、曲面基材１１は、下面がロボットハンド２０９の上面から離れ、テーブル２０へと受け渡される。このとき、ロボットハンド２０９を下方に移動させ、曲面基材１１の下面から離れるようにしてもよい。 Finally, as shown in FIG. 10, the sandwiching member 21 and the support member 23, and the sandwiching member 22 and the support member 24 are moved in the X direction by moving the moving bases 203 and 204 with respect to the table 20. Move closer. Then, one end portion of the curved substrate 11 is clamped by the clamping member 21, and the tubular member 23c is lifted upward from the hole 23e by compressed air or the like from below the bottom 23d, and the support portion of the support member 23 is moved upward. The curved base material 11 is supported from below by the support member 23 by moving up and down. At the same time, the other end of the curved substrate 11 is clamped by the clamping member 22, and the tubular member 24c is lifted upward from the hole 24e by compressed air or the like from below the bottom 24d, and the support of the support member 24 is moved upward. The curved substrate 11 is supported by the support member 24 from below. The operation of the clamping member 25 and the support member 27 in the attachment corresponds to the operation of the clamping member 21 and the support member 23, and the operation of the clamping member 26 and the support member 28 is the operation of the clamping member 22 and the support member 24. Corresponding to Through these series of operations, the lower surface of the curved substrate 11 is separated from the upper surface of the robot hand 209 and transferred to the table 20. At this time, the robot hand 209 may be moved downward to be separated from the lower surface of the curved substrate 11.

本構成によれば、挟持部材２１、２２及び２５、２６が中間線の位置が維持されるよう一体として移動するので、曲面基材１１のサイズが異なっても、曲面基材１１を保持トレイ２の中央部において保持することができ、Ｘ方向における曲面基材１１の長さに合わせて、挟持部材２１、２２及び２５、２６間の距離を容易に調整することができる。また、支持部材２３は、挟持部材２１とＸ方向に沿って一体として移動し、支持部材２４は、挟持部材２２とＸ方向に沿って一体として移動するようになっているので、挟持部材２１及び支持部材２３との位置関係を維持したまま、Ｘ方向に移動させることができ、また、挟持部材２２及び支持部材２４との位置関係を維持したまま、Ｘ方向に移動させることができる。さらに、支持部材２７は、挟持部材２５とＸ方向に沿って一体として移動し、支持部材２８は、挟持部材２６とＸ方向に沿って一体として移動するようになっているので、挟持部材２５及び支持部材２７との位置関係を維持したまま、Ｘ方向に移動させることができ、また、挟持部材２６及び支持部材２８との位置関係を維持したまま、Ｘ方向に移動させることができる。したがって、曲面基材１１の保持のための、挟持部材２１及び支持部材２３、挟持部材２２及び支持部材２４、挟持部材２５及び支持部材２７、挟持部材２６及び支持部材２８の位置調整を容易に行うことができる。 According to this configuration, since the clamping members 21, 22, 25, and 26 move as a unit so that the position of the intermediate line is maintained, the curved base 11 is held in the holding tray 2 even if the curved base 11 is different in size. The distance between the clamping members 21, 22 and 25, 26 can be easily adjusted according to the length of the curved substrate 11 in the X direction. Further, the support member 23 moves integrally with the holding member 21 along the X direction, and the support member 24 moves integrally with the holding member 22 along the X direction. It can be moved in the X direction while maintaining the positional relationship with the support member 23, and can be moved in the X direction while maintaining the positional relationship between the sandwiching member 22 and the support member 24. Further, the support member 27 moves integrally with the holding member 25 along the X direction, and the support member 28 moves integrally with the holding member 26 along the X direction.
