Provided is an attaching device with which production costs can be reduced by shortening the time that it takes to perform attachment, while maintaining quality. A liquid crystal panel (2) and a cover glass (3) are caused to face each other and be separated by only a first distance. While a long nozzle-main body (131) is caused to move between the liquid crystal panel (2) and the cover glass (3) along the short direction of the nozzle main body, a coating liquid is sprayed backward in the movement direction from a slit (131A) along the length direction of the nozzle main body (131), and then the nozzle main body is removed from between the liquid crystal panel (2) and the cover glass (3). The liquid crystal panel (2) and the cover glass (3) are caused to face each other at a second distance that is smaller than the first distance.

Description

貼合せ装置Bonding device
　本発明は、貼合せ装置及び貼合せ方法に関するものである。 The present invention relates to a laminating apparatus and a laminating method.
　上述した貼合せ装置として、特許文献１に示すように、一対のガラス基板を貼合わせる接着剤塗布装置が提案されている。この接着剤塗布装置は、吐出ノズルの先端から接着剤を吐出して、一対のガラス基板の一方に接着剤を塗布する。吐出ノズルの先端から一対のガラス基板の一方に吐出された接着剤はその厚さが均一ではなく、山型に盛られる。その後、接着剤を塗布したガラス基板に接着剤を塗布していないガラス基板を重ねた後、一対のガラス基板を近づけて接着剤の厚さが均一になるように延ばして、一対のガラス基板を貼合わせている。 As the above-described laminating apparatus, as shown in Patent Document 1, an adhesive application apparatus for laminating a pair of glass substrates has been proposed. This adhesive application device discharges an adhesive from the tip of a discharge nozzle and applies the adhesive to one of a pair of glass substrates. The adhesive discharged from one end of the discharge nozzle to one of the pair of glass substrates is not uniform in thickness and is piled up in a mountain shape. Then, after the glass substrate not coated with the adhesive is stacked on the glass substrate coated with the adhesive, the pair of glass substrates are brought close to each other and extended so that the thickness of the adhesive becomes uniform. Pasting.
特開平５－３４５１６０号公報JP-A-5-345160
　しかしながら、上述した従来例では、一方のガラス基板を接着剤の山の頂部に接触させてから、一対のガラス基板の距離を徐々に小さくして当該接着剤を延展し貼合わせていくため、一対のガラス基板を所望の距離に近づけて接着剤の厚さを均一にするまでに時間がかかる、という問題が一例として挙げられる。この接着剤の厚さを均一にするまでの時間を短縮しようとすると、接着剤中に、あるいは接着剤とガラス基板の間に気泡が混入してしまう恐れがあり、品質を保つことが難しい。 However, in the above-described conventional example, since one glass substrate is brought into contact with the top of the adhesive crest, the distance between the pair of glass substrates is gradually reduced, and the adhesive is spread and bonded. As an example, there is a problem that it takes time to bring the glass substrate closer to a desired distance and make the thickness of the adhesive uniform. If an attempt is made to shorten the time required to make the thickness of the adhesive uniform, bubbles may be mixed in the adhesive or between the adhesive and the glass substrate, and it is difficult to maintain quality.
　また、接着剤の流動性は一般的に温度依存性が大きく、当該接着剤の厚さを均一に延展するまでの時間の温度によるばらつきが大きくなりやすい。このため、製造工程の管理が難しく、品質を保つのが難しい、という問題が一例として挙げられる。 In addition, the fluidity of the adhesive generally has a large temperature dependency, and the variation in temperature until the thickness of the adhesive is uniformly spread tends to increase. For this reason, the problem that management of a manufacturing process is difficult and it is difficult to maintain quality is mentioned as an example.
　本発明は、このような問題点に対処することを課題の一例とするものである。即ち、本発明は、例えば、品質を保ちつつ貼合せにかかる時間を短縮することにより、製造コストの削減を図った貼合せ装置及び貼合せ方法を提供することを目的としている。 The present invention is an example of a problem to deal with such problems. That is, an object of the present invention is to provide a laminating apparatus and a laminating method that reduce the manufacturing cost by shortening the time required for laminating while maintaining quality, for example.

A second support member that supports the opposite direction, and a long coating unit that discharges the coating agent while moving between the first bonding member and the second bonding member.

　以下、本発明の一実施形態にかかる貼合せ装置を説明する。本発明の一実施形態にかかる貼合せ装置は、第１の貼合せ部材を支持する第１の支持部材と、第２の貼合せ部材を第１の貼合せ部材に対向するように支持する第２の支持部材と、第１の貼合せ部材と第２の貼合せ部材との間を移動しながら塗布剤を吐出する長尺状の塗布手段と、を有し、塗布手段は、その短手方向に沿って移動し、塗布手段には、その長手方向に沿いかつ塗布手段の移動方向の後方側に、塗布剤が吐出されるスリットが形成されている。 Hereinafter, a laminating apparatus according to an embodiment of the present invention will be described. A laminating apparatus according to an embodiment of the present invention includes a first supporting member that supports a first laminating member and a second laminating member that supports the first laminating member so as to face the first laminating member. 2 and a long coating unit that discharges the coating agent while moving between the first bonding member and the second bonding member. A slit for discharging the coating agent is formed in the coating unit along the longitudinal direction and on the rear side in the moving direction of the coating unit.
　これにより、塗布手段のスリットから移動方向の後方側に吐出された塗布剤を第１の貼合せ部材と第２の貼合せ部材との間に充填させながら、塗布手段が移動する。このように塗布剤を第１の貼合せ部材と第２の貼合せ部材との間に充填することにより、品質を保ちつつ貼合せにかかる時間を短縮でき、製造コストの削減を図ることができる。 Thereby, the coating means moves while filling the coating agent discharged from the slit of the coating means to the rear side in the moving direction between the first bonding member and the second bonding member. Thus, by filling a coating agent between the 1st bonding member and the 2nd bonding member, the time concerning bonding can be shortened, maintaining quality, and the reduction of manufacturing cost can be aimed at. .
　また、塗布手段は、第１の貼合せ部材もしくは第２の貼合せ部材と略平行な管形状であってもよい。 Further, the coating means may be in a tube shape substantially parallel to the first bonding member or the second bonding member.
　また、スリットの長さは、塗布手段の長手方向における第１の貼合せ部材もしくは第２の貼合せ部材の長さよりも小であってもよい。これにより塗布をする工程において塗布剤が第１の貼合せ部材と第２の貼合せ部材と間から漏れ出ることがない。 Further, the length of the slit may be smaller than the length of the first bonding member or the second bonding member in the longitudinal direction of the application means. Thereby, in the process of apply | coating, a coating agent does not leak from between a 1st bonding member and a 2nd bonding member.
　また、塗布手段は、塗布剤が該塗布手段の内部に流入するための開口を有していてもよい。これにより、開口から塗布剤を流入させて、スリットから塗布剤を吐出させることができる。 Further, the coating means may have an opening for allowing the coating agent to flow into the coating means. Thereby, a coating agent can be poured in from an opening and a coating agent can be discharged from a slit.
　また、塗布剤の開口への流入量を制御する塗布剤制御部を有していてもよい。このように塗布剤の流入量を制御することにより、塗布剤のスリットからの単位時間あたりの吐出量を制御することができる。 Further, it may have a coating agent control unit that controls the amount of the coating agent flowing into the opening. By controlling the inflow amount of the coating agent in this way, the discharge amount per unit time from the slit of the coating agent can be controlled.
　また、塗布手段は、塗布剤の塗布時において第１の貼合せ部材もしくは第２の貼合せ部材の表面形状に沿って移動するようにしてもよい。これにより、例えば、第１の貼合せ部材もしくは第２の貼合せ部材の表面形状が曲面であれば塗布手段はその曲面に沿って曲がりながら移動する。このため、第１の貼合せ部材もしくは第２の貼合せ部材の表面形状が曲面であっても第１の貼合せ部材と第２の貼合せ部材との間に塗布剤を充填することができる。 Further, the applying means may move along the surface shape of the first bonding member or the second bonding member when applying the coating agent. Thereby, for example, if the surface shape of the first bonding member or the second bonding member is a curved surface, the coating means moves while bending along the curved surface. For this reason, even if the surface shape of the 1st bonding member or the 2nd bonding member is a curved surface, it can be filled with a coating agent between the 1st bonding member and the 2nd bonding member. .
　また、塗布手段は、塗布剤の塗布時において、第１の貼合せ部材と第２の貼合せ部材との何れかにより近い位置を保って移動するようにしてもよい。これにより、接着剤中に、あるいは接着剤と第１の貼合せ部材もしくは第２の貼合せ部材との間に気泡が入ることなく、塗布剤を第１の貼合せ部材と第２の貼合せ部材との間に確実に充填できる。 Further, the application means may be moved while maintaining a position closer to either the first bonding member or the second bonding member when applying the coating agent. As a result, the first adhesive member and the second adhesive are bonded to each other without air bubbles entering the adhesive or between the adhesive and the first adhesive member or the second adhesive member. It can be reliably filled between the members.
　また、第１の支持部材及び第２の支持部材は、第１の貼合せ部材と第２の貼合せ部材とを上下方向に対向するように支持してもよい。また、スリットは、上方に向かって開口してもよい。これにより、接着剤中に、あるいは接着剤と第１の貼合せ部材もしくは第２の貼合せ部材との間に気泡が入ることなく、塗布剤を第１の貼合せ部材と第２の貼合せ部材との間に確実に充填できる。 Further, the first support member and the second support member may support the first bonding member and the second bonding member so as to face each other in the vertical direction. The slit may be opened upward. As a result, the first adhesive member and the second adhesive are bonded to each other without air bubbles entering the adhesive or between the adhesive and the first adhesive member or the second adhesive member. It can be reliably filled between the members.
　また、第１の支持部材と第２の支持部材は、塗布剤の塗布時において、第１の貼合せ部材と第２の貼合せ部材との間の距離を、塗布手段の上下方向における長さの２倍以下になるように支持してもよい。これにより、より確実に、塗布剤を第１の貼合せ部材と第２の貼合せ部材との間に充填できる。 In addition, the first support member and the second support member are configured so that the distance between the first bonding member and the second bonding member is the length in the vertical direction of the coating unit when the coating agent is applied. You may support so that it may become 2 times or less. Thereby, a coating agent can be more reliably filled between the 1st bonding member and the 2nd bonding member.
　また、第１の支持部材と第２の支持部材は、塗布剤の塗布後において、第１の貼合せ部材と第２の貼合せ部材との間の距離を、塗布手段の上下方向における長さ以下になるように支持してもよい。これにより、塗布剤を第１の貼合せ部材と第２の貼合せ部材の間に十分に延展することができる。 In addition, the first support member and the second support member are configured so that the distance between the first bonding member and the second bonding member is the length in the vertical direction of the coating unit after the coating agent is applied. You may support so that it may become the following. Thereby, an application agent can be fully extended between the 1st bonding member and the 2nd bonding member.
　また、第１の支持部材と第２の支持部材は、塗布剤の塗布時において、第１の貼合せ部材と第２の貼合せ部材との距離を、塗布手段から吐出された塗布剤が第１の貼合せ部材と第２の貼合せ部材との間に充填されるような距離に支持してもよい。 In addition, the first support member and the second support member are configured so that the distance between the first bonding member and the second bonding member is the distance between the first bonding member and the second bonding member when the coating agent discharged from the coating means is first. You may support to the distance which is filled between 1 bonding member and 2nd bonding member.
　また、塗布剤は、紫外線硬化型の接着剤を含んでもよい。 Further, the coating agent may include an ultraviolet curable adhesive.
　また、第１の貼合せ部材は表示装置であり、第２の貼合せ部材はカバー部材であってもよい。これにより、表示装置とカバー部材とを貼合わせることができる。 Further, the first bonding member may be a display device, and the second bonding member may be a cover member. Thereby, a display apparatus and a cover member can be bonded together.
　また、カバー部材にはタッチパネルが形成されていてもよい。 Further, a touch panel may be formed on the cover member.
　次に、本発明の一実施形態にかかる貼合せ方法を説明する。本発明の一実施形態にかかる貼合せ方法は、第１の貼合せ部材と第２の貼合せ部材を第１の距離だけ離間して対向させる第１工程と、長尺状の塗布手段を第１の貼合せ部材と第２の貼合せ部材との間においてその短手方向に沿って移動させながら、塗布手段の長手方向に沿ったスリットからその移動方向の後方に塗布剤を吐出させた後、第１の貼合せ部材と第２の貼合せ部材との間から塗布手段を抜く第２工程と、第１の貼合せ部材と第２の貼合せ部材を第１の距離よりも小さい第２の距離に対向させる第３工程と、を有する。 Next, a bonding method according to an embodiment of the present invention will be described. A laminating method according to an embodiment of the present invention includes: a first step in which a first laminating member and a second laminating member are opposed to each other with a first distance; After discharging the coating agent from the slit along the longitudinal direction of the coating means to the rear in the moving direction while moving along the short direction between the 1 bonding member and the second bonding member The second step of removing the coating means from between the first bonding member and the second bonding member, and the second step in which the first bonding member and the second bonding member are smaller than the first distance. And a third step of facing the distance.
　これにより、塗布手段のスリットから移動方向の後方側に吐出された塗布剤を第１の貼合せ部材と第２の貼合せ部材との間に充填させながら、塗布手段が移動する。このように塗布剤を第１の貼合せ部材と第２の貼合せ部材との間に充填することにより、品質を保ちつつ貼合せにかかる時間を短縮でき、製造コストの削減を図ることができる。 Thereby, the coating means moves while filling the coating agent discharged from the slit of the coating means to the rear side in the moving direction between the first bonding member and the second bonding member. Thus, by filling a coating agent between the 1st bonding member and the 2nd bonding member, the time concerning bonding can be shortened, maintaining quality, and the reduction of manufacturing cost can be aimed at. .
　また、第３工程において、第１の貼合せ部材を支持する第１の支持部材と第２の貼合せ部材を支持する第２の支持部材とを互いに近づけてもよい。 In the third step, the first support member that supports the first bonding member and the second support member that supports the second bonding member may be brought closer to each other.
　また、第２工程において、第１の貼合せ部材と第２の貼合せ部材との間の一部の空間に塗布剤を充填するように塗布する。 In the second step, coating is performed so as to fill a part of the space between the first bonding member and the second bonding member.
　また、第１工程において、第１の貼合せ部材と第２の貼合せ部材とが上下方向に対向され、第２工程において、塗布手段から塗布剤が上方に向かって吐出される。これにより、接着剤中に、あるいは接着剤と第１の貼合せ部材もしくは第２の貼合せ部材との間に気泡が入ることなく、塗布剤を第１の貼合せ部材と第２の貼合せ部材との間に確実に充填できる。 In the first step, the first bonding member and the second bonding member are opposed to each other in the vertical direction, and in the second step, the coating agent is discharged upward from the coating means. As a result, the first adhesive member and the second adhesive are bonded to each other without air bubbles entering the adhesive or between the adhesive and the first adhesive member or the second adhesive member. It can be reliably filled between the members.
　また、第２工程において、塗布手段のスリットは、第１の貼合せ部材と第２の貼合せ部材との間の中心よりも上方に位置する。これにより、より確実に、塗布剤を第１の貼合せ部材と第２の貼合せ部材との間に充填できる。 Also, in the second step, the slit of the application means is located above the center between the first bonding member and the second bonding member. Thereby, a coating agent can be more reliably filled between the 1st bonding member and the 2nd bonding member.
　また、第３工程の後、塗布剤を硬化させる第４工程を含んでもよい。 Further, after the third step, a fourth step of curing the coating agent may be included.
　また、塗布剤が、紫外線硬化型の接着剤であり、第４工程が、塗布剤に紫外線を照射する工程であってもよい。 Further, the coating agent may be an ultraviolet curable adhesive, and the fourth step may be a step of irradiating the coating agent with ultraviolet rays.

　上述した第１の支持部材１１及び第２の支持部材１２は、第１の水平アーム１１３及び第２の水平アーム１２２が上から見て交差し（本実施形態では直交）、かつ、第１の支持台１１４及び第２の支持台１２３が上下に離間するように配置されている。これにより、第１の支持部材１１及び第２の支持部材１２は、液晶パネル２とカバーガラス３とを上下方向に対向するように支持することができる。本実施形態では、液晶パネル２が下側、カバーガラス３が上側になるように支持されて場合について説明するが、その逆でもよい。 The first support member 11 and the second support member 12 described above intersect the first horizontal arm 113 and the second horizontal arm 122 as viewed from above (orthogonal in the present embodiment), and the first The support table 114 and the second support table 123 are arranged so as to be separated from each other in the vertical direction. Thereby, the 1st supporting member 11 and the 2nd supporting member 12 can support the liquid crystal panel 2 and the cover glass 3 so that it may oppose an up-down direction. In the present embodiment, a case where the liquid crystal panel 2 is supported on the lower side and the cover glass 3 is supported on the upper side will be described, but the reverse may be possible.
　ノズル１３は、長尺状の円管形状に形成され、塗布剤４が吐出されるスリット１３１Ａ（図２参照）が設けられたノズル本体１３１と、ノズル本体１３１の両端に取り付けられ、塗布剤４の供給源（図示せず）に接続されたチューブ（図示せず）を接続するための一対の接続部１３２と、を備えている。このノズル１３は、後述する一対の移動機構１４により支持され、ノズル本体１３１が、図２（Ａ）に示すように、液晶パネル２とカバーガラス３との間に、液晶パネル２とカバーガラス３と略平行に配置されている。 The nozzle 13 is formed in a long circular tube shape, and is attached to both ends of the nozzle body 131 provided with slits 131 </ b> A (see FIG. 2) through which the coating agent 4 is discharged. A pair of connecting portions 132 for connecting a tube (not shown) connected to a supply source (not shown). The nozzle 13 is supported by a pair of moving mechanisms 14 to be described later, and the nozzle body 131 is disposed between the liquid crystal panel 2 and the cover glass 3 as shown in FIG. Are arranged substantially in parallel.
　また、上記ノズル１３は、後述する移動機構１４によりノズル本体１３１の短手方向に移動可能に設けられている。これにより、ノズル本体１３１は、液晶パネル２とカバーガラス３との間をその短手方向に沿って、かつ、液晶パネル２及びカバーガラス３の表面形状に沿って移動する。また、ノズル本体１３１は、液晶パネル２とカバーガラス３との中間ではなく、中間よりも下側に配置された液晶パネル２よりに設けられている。このため、ノズル本体１３１は、液晶パネル２により近い位置を保って移動することになる。 The nozzle 13 is provided so as to be movable in the short direction of the nozzle body 131 by a moving mechanism 14 described later. As a result, the nozzle body 131 moves between the liquid crystal panel 2 and the cover glass 3 along the short direction and along the surface shapes of the liquid crystal panel 2 and the cover glass 3. The nozzle body 131 is provided not on the middle between the liquid crystal panel 2 and the cover glass 3 but on the liquid crystal panel 2 disposed below the middle. For this reason, the nozzle body 131 moves while maintaining a position closer to the liquid crystal panel 2.
　上記スリット１３１Ａは、図２に示すように、ノズル本体１３１の長手方向に沿いかつノズル本体１３１の移動方向の後方側に形成されている。また、このスリット１３１Ａは、下方に向かって開口している。このスリット１３１Ａの長さＬ１は、ノズル本体１３１の長手方向における液晶パネル２の長さＬ２、カバーガラス３の長さＬ３よりも小になっている。本実施形態では、液晶パネル２の長さＬ２の方がカバーガラス３の長さＬ２よりも小さいため、スリット１３１Ａの長さＬ１は液晶パネル２の長さＬ２よりも小さければよい。 The slit 131A is formed along the longitudinal direction of the nozzle body 131 and on the rear side in the moving direction of the nozzle body 131, as shown in FIG. Further, the slit 131A is opened downward. The length L1 of the slit 131A is smaller than the length L2 of the liquid crystal panel 2 and the length L3 of the cover glass 3 in the longitudinal direction of the nozzle body 131. In the present embodiment, since the length L2 of the liquid crystal panel 2 is smaller than the length L2 of the cover glass 3, the length L1 of the slit 131A only needs to be smaller than the length L2 of the liquid crystal panel 2.
　また、ノズル本体１３１は、その長手方向両端に塗布剤４を内部に流入するための開口を有している。一対の接続部１３２によってノズル本体１３１の両端開口と図示しないチューブを接続することにより、供給源から供給された塗布剤４がチューブを通ってノズル本体１３１の両端開口から内部に流入する。このノズル本体１３１の開口への塗布剤４の単位時間あたりの流入量は、図示しない塗布剤制御部により制御されている。 Moreover, the nozzle body 131 has openings for allowing the coating agent 4 to flow inside at both ends in the longitudinal direction. By connecting the opening at both ends of the nozzle body 131 and a tube (not shown) by the pair of connecting portions 132, the coating agent 4 supplied from the supply source flows into the inside from the opening at both ends of the nozzle body 131 through the tube. The amount of the coating agent 4 flowing into the opening of the nozzle body 131 per unit time is controlled by a coating agent control unit (not shown).
　一対の移動機構１４は、それぞれノズル本体１３１の短手方向に延びる移動レール１４１と、図示しないモータの駆動力により、移動レール１４１に沿って移動可能に設けられたスライダ１４２と、を備えている。このスライダ１４２にノズル１３の両端が搭載されている。これにより、図示しないモータによりスライダ１４２を移動レール１４１に沿って移動させることにより、スライダ１４２に支持されたノズル１３をその短手方向に沿って動かすことができる。 Each of the pair of moving mechanisms 14 includes a moving rail 141 that extends in the short direction of the nozzle body 131 and a slider 142 that can be moved along the moving rail 141 by a driving force of a motor (not shown). . Both ends of the nozzle 13 are mounted on the slider 142. Thereby, the nozzle 13 supported by the slider 142 can be moved along the short direction by moving the slider 142 along the moving rail 141 by a motor (not shown).
　次に、上述した貼合せ装置１を用いた本発明の貼合せ方法について図３～図６を参照して説明する。なお、図４～図６においては第１の支持部材１１及び第２の支持部材１２の図示を省略している。まず、液晶パネル２を第１の支持台１１４に搭載し、カバーガラス３を第２の支持台１２３に吸着させる。その後、第１の支持部材１１のスライダ１１２を上下レール１１１に沿って移動させて、液晶パネル２を上に動かしてカバーガラス３に近づける。そして、液晶パネル２とカバーガラス３との距離が第１の距離Ｄ１になったところでスライダ１１２の移動を停止させる。これにより、液晶パネル２とカバーガラス３とが第１の距離Ｄ１だけ離間して上下方向に対向する（図３の第１工程）。 Next, the bonding method of the present invention using the above-described bonding apparatus 1 will be described with reference to FIGS. 4 to 6, illustration of the first support member 11 and the second support member 12 is omitted. First, the liquid crystal panel 2 is mounted on the first support base 114, and the cover glass 3 is adsorbed on the second support base 123. Thereafter, the slider 112 of the first support member 11 is moved along the upper and lower rails 111, and the liquid crystal panel 2 is moved upward to approach the cover glass 3. Then, when the distance between the liquid crystal panel 2 and the cover glass 3 becomes the first distance D1, the movement of the slider 112 is stopped. Thereby, the liquid crystal panel 2 and the cover glass 3 are separated from each other by the first distance D1 and face each other in the vertical direction (first step in FIG. 3).
　上記第１の距離Ｄ１は、図２（Ｂ）に示すように、ノズル本体１３１の上下方向における長さ、即ち本実施形態ではノズル本体１３１は円管状に設けられているためその径Ｒの２倍以下になるようにしている。その一例を述べると第１の距離Ｄ１＝３．０ｍｍ、径Ｒ＝１．６ｍｍに設定されている。 As shown in FIG. 2B, the first distance D1 is the length in the vertical direction of the nozzle body 131, that is, the diameter R of 2 because the nozzle body 131 is provided in a circular tube shape in this embodiment. I try to be less than double. For example, the first distance D1 is set to 3.0 mm and the diameter R is set to 1.6 mm.
　このとき、液晶パネル２とカバーガラス３との間にノズル本体１３１が配置される。ノズル本体１３１は、液晶パネル２とカバーガラス３との間のノズル本体１３１の移動方向の後方側の端部に近い位置に配置されている。また、ノズル本体１３１は、カバーガラス３よりも液晶パネル２の近くに配置される。 At this time, the nozzle body 131 is disposed between the liquid crystal panel 2 and the cover glass 3. The nozzle body 131 is disposed at a position close to an end on the rear side in the moving direction of the nozzle body 131 between the liquid crystal panel 2 and the cover glass 3. Further, the nozzle body 131 is disposed closer to the liquid crystal panel 2 than the cover glass 3.
　次に、一対の移動機構１４のスライダ１４２を移動レール１４１に沿って移動させて、ノズル１３を動かす。また、図示しない塗布剤制御部が、ノズル１３に塗布剤４を供給して、スリット１３１Ａから塗布剤４を吐出させる。これにより、ノズル本体１３１が液晶パネル２とカバーガラス３との間において移動させながら、ノズル本体１３１に設けたスリット１３１Ａからその移動方向の後方に塗布剤４を吐出させる（図４及び図５の第２工程）。ノズル本体１３１の移動速度は例えば１５～３５ｍｍ／ｓｅｃ程度で、ほぼ一定速度で移動させる。これにより、ノズル本体１３１のスリット１３１Ａから移動方向の後方側に吐出された塗布剤４を液晶パネル２とカバーガラス３との間に充填させながら、ノズル本体１３１が移動する。 Next, the slider 142 of the pair of moving mechanisms 14 is moved along the moving rail 141 to move the nozzle 13. Further, a coating agent control unit (not shown) supplies the coating agent 4 to the nozzle 13 and discharges the coating agent 4 from the slit 131A. As a result, while the nozzle body 131 is moved between the liquid crystal panel 2 and the cover glass 3, the coating agent 4 is discharged to the rear in the moving direction from the slit 131A provided in the nozzle body 131 (FIGS. 4 and 5). Second step). The moving speed of the nozzle body 131 is, for example, about 15 to 35 mm / sec, and is moved at a substantially constant speed. As a result, the nozzle body 131 moves while filling the coating material 4 discharged from the slit 131 </ b> A of the nozzle body 131 to the rear side in the movement direction between the liquid crystal panel 2 and the cover glass 3.
　なお、塗布剤４はノズル本体１３１の移動中、ずっと吐出されているわけではなく、液晶パネル２およびカバーガラス３の中央部を移動している間だけ吐出されている。これにより、図５に示すように、液晶パネル２およびカバーガラス３の中央部だけに塗布剤４が充填される。ノズル本体１３１は、図１（Ｂ）の点線で示すように、液晶パネル２とカバーガラス３との間から外れる位置まで移動される。 The coating agent 4 is not discharged all the time during the movement of the nozzle body 131, but is discharged only while moving in the central part of the liquid crystal panel 2 and the cover glass 3. Thereby, as shown in FIG. 5, only the center part of the liquid crystal panel 2 and the cover glass 3 is filled with the coating agent 4. The nozzle body 131 is moved to a position where it is removed from between the liquid crystal panel 2 and the cover glass 3 as indicated by a dotted line in FIG.
　その後、第１の支持部材１１のスライダ１１２を上下レール１１１に沿って移動させて、液晶パネル２をカバーガラス３に徐々に近づけて、塗布剤４を延展する。そして、液晶パネル２とカバーガラス３との距離が第１の距離Ｄ１よりも小さい第２の距離Ｄ２になるまでスライダ１１２を移動させる。これにより、液晶パネル２とカバーガラス３とが塗布剤４を挟んで第２の距離Ｄ２だけ離間して対向する。（図６の第３工程）。第２の距離Ｄ２としては、ノズル本体１３１の径以下の例えば０．３ｍｍに設定する。その後、塗布剤４に紫外線を照射して硬化する第４工程を経て液晶パネル２とカバーガラス３の貼合せが完了する。 Thereafter, the slider 112 of the first support member 11 is moved along the upper and lower rails 111, the liquid crystal panel 2 is gradually brought closer to the cover glass 3, and the coating agent 4 is spread. Then, the slider 112 is moved until the distance between the liquid crystal panel 2 and the cover glass 3 becomes a second distance D2 that is smaller than the first distance D1. As a result, the liquid crystal panel 2 and the cover glass 3 face each other with the coating agent 4 sandwiched therebetween by a second distance D2. (Third step in FIG. 6). The second distance D2 is set to, for example, 0.3 mm which is equal to or less than the diameter of the nozzle body 131. Then, pasting of liquid crystal panel 2 and cover glass 3 is completed through the 4th process of irradiating ultraviolet rays to coating agent 4, and hardening.
　上述した実施形態によれば、ノズル本体１３１のスリット１３１Ａから移動方向の後方側に吐出された塗布剤４を液晶パネル２とカバーガラス３との間に充填させながら、ノズル本体１３１が移動する。このように塗布剤４を液晶パネル２とカバーガラス３との間に充填することにより、塗布剤４を均一な厚さで液晶パネル２とカバーガラス３とに塗布することができる。このため、塗布剤４を塗布した後、液晶パネル２とカバーガラス３とを素早く近づけても接着剤中に、あるいは接着剤と第１の貼合せ部材もしくは第２の貼合せ部材との間に気泡が入りにくく、また当該接着剤の厚さを均一に延展するまでの時間の温度によるばらつきも少ない。よって、品質を保ちつつ貼合せにかかる時間を短縮でき、製造コストの削減を図ることができる。 According to the above-described embodiment, the nozzle body 131 moves while the coating agent 4 discharged from the slit 131A of the nozzle body 131 to the rear side in the movement direction is filled between the liquid crystal panel 2 and the cover glass 3. Thus, by filling the coating agent 4 between the liquid crystal panel 2 and the cover glass 3, the coating agent 4 can be applied to the liquid crystal panel 2 and the cover glass 3 with a uniform thickness. For this reason, after apply | coating the coating agent 4, even if the liquid crystal panel 2 and the cover glass 3 are brought close quickly, in an adhesive agent or between an adhesive agent and a 1st bonding member or a 2nd bonding member. It is difficult for bubbles to enter, and there is little variation due to the temperature of the time until the thickness of the adhesive is uniformly spread. Therefore, it is possible to shorten the time required for bonding while maintaining the quality, and to reduce the manufacturing cost.
　また、上述した実施形態によれば、スリット１３１Ａの長さＬ１は、ノズル本体１３１の長手方向における液晶パネル２とカバーガラス３の長さＬ２、Ｌ３よりも小である。これにより、塗布をする工程において塗布剤４が液晶パネル２とカバーガラス３と間から漏れ出ることがない。 Further, according to the embodiment described above, the length L1 of the slit 131A is smaller than the lengths L2 and L3 of the liquid crystal panel 2 and the cover glass 3 in the longitudinal direction of the nozzle body 131. Thereby, the coating agent 4 does not leak from between the liquid crystal panel 2 and the cover glass 3 in the coating step.
　また、上述した実施形態によれば、ノズル本体１３１は、塗布剤４が該ノズル本体１３１の内部に流入するための開口を有している。これにより、開口から塗布剤４を流入させて、スリット１３１Ａから塗布剤４を吐出させることができる。 Further, according to the above-described embodiment, the nozzle body 131 has an opening through which the coating agent 4 flows into the nozzle body 131. Thereby, the coating agent 4 can be made to flow in from an opening, and the coating agent 4 can be discharged from the slit 131A.
　また、上述した実施形態によれば、塗布剤４の開口への流入量を制御する塗布剤制御部（図示せず）を有している。このように塗布剤４の流入量を制御することにより、塗布剤４のスリット１３１Ａからの単位時間当たりの吐出量を制御することができる。 Further, according to the above-described embodiment, the coating agent control unit (not shown) for controlling the amount of the coating agent 4 flowing into the opening is provided. By controlling the inflow amount of the coating agent 4 in this manner, the discharge amount per unit time from the slit 131A of the coating agent 4 can be controlled.
　また、上述した実施形態によれば、ノズル本体１３１は、塗布剤４の塗布時において、液晶パネル２により近い位置を保って移動している。これにより、接着剤中に、あるいは接着剤と第１の貼合せ部材もしくは第２の貼合せ部材との間に気泡が入ることなく、塗布剤４を液晶パネル２とカバーガラス３との間に確実に充填できる。 Further, according to the above-described embodiment, the nozzle body 131 moves while maintaining a position closer to the liquid crystal panel 2 when the coating agent 4 is applied. Accordingly, the coating agent 4 is placed between the liquid crystal panel 2 and the cover glass 3 without bubbles in the adhesive or between the adhesive and the first bonding member or the second bonding member. Can be filled reliably.
　また、上述した実施形態によれば、第１の支持部材１１及び第２の支持部材１２は、塗布剤の塗布時において、液晶パネル２とカバーガラス３との間の距離を、ノズル本体１３１の径Ｒの２倍以下になるように支持している。これにより、接着剤中に、あるいは接着剤と第１の貼合せ部材もしくは第２の貼合せ部材との間に気泡が入ることなく、塗布剤を液晶パネル２とカバーガラス３との間に確実に充填できる。 Further, according to the above-described embodiment, the first support member 11 and the second support member 12 determine the distance between the liquid crystal panel 2 and the cover glass 3 when the coating agent is applied. It supports so that it may become 2 times or less of diameter R. Accordingly, the coating agent can be reliably placed between the liquid crystal panel 2 and the cover glass 3 without bubbles in the adhesive or between the adhesive and the first bonding member or the second bonding member. Can be filled.
　また、上述した実施形態によれば、第１の支持部材１１と第２の支持部材１２は、塗布剤４の塗布後において、液晶パネル２とカバーガラス３との間の第２の距離Ｄ２を、ノズル本体１３１の径Ｒ以下になるように支持している。これにより、塗布剤４を十分に延展することができる。 Further, according to the above-described embodiment, the first support member 11 and the second support member 12 have the second distance D2 between the liquid crystal panel 2 and the cover glass 3 after the coating agent 4 is applied. The nozzle body 131 is supported so as to have a diameter R or less. Thereby, the coating agent 4 can fully be extended.
　なお、上述した実施形態によれば、ノズル１３を駆動して、液晶パネル２とカバーガラス３との間をノズル本体１３１が移動するようにしていたが、これに限ったものではない。第１の支持部材１１及び第２の支持部材１２を駆動して、図７に示すように、液晶パネル２とカバーガラス３とを動かして、液晶パネル２とカバーガラス３との間をノズル本体１３１が移動するようにしてもよい。なお、図７においては、第１の支持部材１１及び第２の支持部材１２については省略している。 In the above-described embodiment, the nozzle 13 is driven to move the nozzle body 131 between the liquid crystal panel 2 and the cover glass 3. However, the present invention is not limited to this. The first support member 11 and the second support member 12 are driven to move the liquid crystal panel 2 and the cover glass 3 as shown in FIG. 131 may be moved. In FIG. 7, the first support member 11 and the second support member 12 are omitted.
　また、上述した実施形態によれば、液晶パネル２とカバーガラス３とは平板に設けられていたためノズル本体１３１を液晶パネル２及びカバーガラス３の表面形状である平面に沿ってまっすぐに移動させていたが、これに限ったものではない。例えば、図８に示すように、液晶パネル２及びカバーガラス３が湾曲している場合、液晶パネル２及びカバーガラス３の表面の曲面に沿って曲がりながら移動させるようにしてもよい。なお、図８においては、第１の支持部材１１及び第２の支持部材１２については省略している。 Further, according to the above-described embodiment, the liquid crystal panel 2 and the cover glass 3 are provided on a flat plate, so that the nozzle body 131 is moved straight along the plane that is the surface shape of the liquid crystal panel 2 and the cover glass 3. However, it is not limited to this. For example, as shown in FIG. 8, when the liquid crystal panel 2 and the cover glass 3 are curved, the liquid crystal panel 2 and the cover glass 3 may be moved while being bent along the curved surfaces of the surfaces of the liquid crystal panel 2 and the cover glass 3. In FIG. 8, the first support member 11 and the second support member 12 are omitted.
　また、上述した実施形態によれば、図２（Ｂ）に示すように、ノズル本体１３１を下側の液晶パネル２に近い位置を保って移動させ、さらにスリット１３１Ａを下方に向けて開口させていたが、これに限ったものではない。例えば、図９に示すように、ノズル本体１３１を上側のカバーガラス３に近い位置を保って移動させ、さらにスリット１３１Ａを上方に向けて開口させることが考えられる。これによれば、上側のカバーガラス３に塗布された塗布剤が重力により下側の液晶パネル２にも塗布されやすくなるため、接着剤中に、あるいは接着剤と第１の貼合せ部材もしくは第２の貼合せ部材との間に気泡などが含まれることなく確実に液晶パネル２とカバーガラス３との間に塗布剤を確実に充填させることができる。 Further, according to the embodiment described above, as shown in FIG. 2B, the nozzle body 131 is moved while maintaining a position close to the lower liquid crystal panel 2, and the slit 131A is opened downward. However, it is not limited to this. For example, as shown in FIG. 9, it can be considered that the nozzle body 131 is moved while maintaining a position close to the upper cover glass 3, and the slit 131A is opened upward. According to this, since the coating agent applied to the upper cover glass 3 is easily applied to the lower liquid crystal panel 2 by gravity, the adhesive is applied to the adhesive or the first bonding member or the first bonding member. It is possible to reliably fill the coating agent between the liquid crystal panel 2 and the cover glass 3 without including bubbles or the like between the two bonding members.
　また、上述した実施形態によれば、液晶パネル２とカバーガラス３とは上下方向に対向するように配置されていたが、これに限ったものではない。例えば、水平方向に対向するように配置されていてもよい。 Further, according to the above-described embodiment, the liquid crystal panel 2 and the cover glass 3 are arranged so as to face each other in the vertical direction, but the present invention is not limited to this. For example, you may arrange | position so that it may oppose in a horizontal direction.
　また、上述した実施形態によれば、第１の支持部材１１と第２の支持部材１２は、塗布剤４の塗布時において液晶パネル２とカバーガラス３との間の第１の距離Ｄ１をノズル本体１３１の径Ｒの２倍以下になるように支持していたが、これに限ったものではない。第１の距離Ｄ１としては、ノズル１３からの塗布剤４の単位時間あたりの吐出量を適度に制御した上で、液晶パネル２とカバーガラス３との間に塗布剤４が充填されるような距離であればよい。 Further, according to the above-described embodiment, the first support member 11 and the second support member 12 nozzle the first distance D1 between the liquid crystal panel 2 and the cover glass 3 when the coating agent 4 is applied. The main body 131 is supported so as to be not more than twice the diameter R of the main body 131, but is not limited thereto. As the first distance D1, the coating agent 4 is filled between the liquid crystal panel 2 and the cover glass 3 after appropriately controlling the discharge amount of the coating agent 4 from the nozzle 13 per unit time. Any distance is sufficient.
　また、上述した実施形態によれば、第１の貼合せ部材として液晶パネル２、第２の貼合せ部材としてカバーガラス３を例に挙げて説明していたがこれに限ったものではない。たとえば第１の貼合せ部材として有機ＥＬパネル、第２の貼合せ部材としてハーフミラー基板など、第１の貼合せ部材、第２の貼合せ部材は、互いに貼合せたい部材であればどんな部材であってもよい。 Further, according to the above-described embodiment, the liquid crystal panel 2 is described as an example of the first bonding member, and the cover glass 3 is described as an example of the second bonding member, but the present invention is not limited thereto. For example, the organic EL panel as the first bonding member, the half mirror substrate as the second bonding member, etc., the first bonding member and the second bonding member are any members as long as they are members to be bonded to each other. There may be.
　また、前述した実施例は本発明の代表的な形態を示したに過ぎず、本発明は、実施形態に限定されるものではない。即ち、本発明の骨子を逸脱しない範囲で種々変形して実施することができる。 Further, the above-described embodiments are merely representative forms of the present invention, and the present invention is not limited to the embodiments.
