Description

本発明は、液晶ディスプレイ等の光学表示デバイスの生産システム及び生産方法に関する。   The present invention relates to a production system and production method for an optical display device such as a liquid crystal display.
従来、液晶ディスプレイ等の光学表示デバイスの生産システムにおいて、液晶パネル(光学表示部品)に貼合する偏光板等の光学部材は、長尺フィルムから液晶パネルの表示領域に合わせたサイズのシート片に切り出され、梱包されて別ラインに搬送された後、液晶パネルに貼合されることがある(例えば、特許文献1参照)。   Conventionally, in a production system for an optical display device such as a liquid crystal display, an optical member such as a polarizing plate to be bonded to a liquid crystal panel (optical display component) is formed from a long film into a sheet piece having a size matching the display area of the liquid crystal panel After being cut out, packed and transported to another line, it may be bonded to a liquid crystal panel (see, for example, Patent Document 1).
特開2003−255132号公報JP 2003-255132 A
しかし、上記従来の構成では、液晶パネル及びシート片の各寸法バラツキ、並びに液晶パネルに対するシート片の貼合バラツキ(位置ズレ)を考慮して、表示領域よりも若干大きめのシート片を切り出している。そのため、表示領域の周辺部に余分な領域(額縁部)が形成され、機器の小型化が阻害されるという問題がある。
また、液晶パネルに光学部材を貼合する前には、液晶パネルの静電気の除去等により液晶パネルに塵埃が付着することを抑えているが、液晶パネルに貼り合わされる光学部材の貼合面は粘着性を有することから塵埃が付着し易く、貼合不良を発生させる一因となるという問題がある。
However, in the conventional configuration described above, a sheet piece slightly larger than the display area is cut out in consideration of variation in dimensions of the liquid crystal panel and the sheet piece, and bonding variation (positional deviation) of the sheet piece to the liquid crystal panel. . Therefore, there is a problem that an extra area (frame part) is formed around the display area, and downsizing of the device is hindered.
In addition, before the optical member is bonded to the liquid crystal panel, dust is prevented from adhering to the liquid crystal panel by removing static electricity from the liquid crystal panel, but the bonding surface of the optical member bonded to the liquid crystal panel is Since it has adhesiveness, there is a problem that dust easily adheres and contributes to poor bonding.
本発明は上記事情に鑑みてなされたもので、表示領域周辺の額縁部を縮小して表示エリアの拡大及び機器の小型化を図り、かつ光学部材の貼合面に塵埃が付着することを抑制することができる光学表示デバイスの生産システム及び生産方法を提供する。   The present invention has been made in view of the above circumstances, and reduces the frame portion around the display area to enlarge the display area and downsize the device, and suppresses dust from adhering to the bonding surface of the optical member. An optical display device production system and production method are provided.

図1及び図10に示すように、第三貼合装置18は、第三光学部材シートF3をこれに重なるセパレータシートSSと共に巻回した第三原反ロールR3から第三光学部材シートF3及びセパレータシートSSを巻き出しつつ搬送すると共に第三光学部材シートF3から第三光学部材F13を切り出して貼合位置に供給する搬送装置19と、搬送装置19が第三光学部材シートF3から切り出した第三光学部材F13の上面をローラコンベヤ5が搬送する第二片面貼合パネルP12の下面(液晶パネルPの表示面側)に貼合する挟圧ロール21とを備える。   As shown in FIG.1 and FIG.10, the 3rd bonding apparatus 18 is the 3rd optical member sheet | seat F3 and separator from the 3rd original fabric roll R3 which wound the 3rd optical member sheet | seat F3 with separator sheet SS which overlaps this. The transport device 19 that transports the sheet SS while unwinding and feeds the third optical member F13 from the third optical member sheet F3 to the bonding position, and the third transport device 19 cuts from the third optical member sheet F3. A pressing roll 21 is provided that bonds the upper surface of the optical member F13 to the lower surface (display surface side of the liquid crystal panel P) of the second single-sided bonding panel P12 that the roller conveyor 5 conveys.
搬送装置19は、セパレータシートSSをキャリアとして複数の第三光学部材F13を連続的に搬送する。第三光学部材シートF3及びセパレータシートSSは、前記部品幅方向で液晶パネルPの表示領域P4に対応する幅(本実施形態では表示領域P4の全幅以上で液晶パネルPの全幅以下の幅に相当)を有する長尺の帯状とされる。セパレータシートSSは、第三光学部材シートF3(第三光学部材F13)に重なって分離可能に貼合される。以下、セパレータシートSSと第三光学部材シートF3との組み合わせを第三光学部材シート体F3Sという。   The transport device 19 continuously transports the plurality of third optical members F13 using the separator sheet SS as a carrier. The third optical member sheet F3 and the separator sheet SS correspond to the width corresponding to the display area P4 of the liquid crystal panel P in the component width direction (corresponding to the width not less than the entire width of the display area P4 and not more than the entire width of the liquid crystal panel P in this embodiment). ). Separator sheet SS overlaps with 3rd optical member sheet | seat F3 (3rd optical member F13), and is bonded so that isolation | separation is possible. Hereinafter, the combination of the separator sheet SS and the third optical member sheet F3 is referred to as a third optical member sheet body F3S.
搬送装置19は、第三原反ロールR3を保持すると共にこの第三原反ロールR3から第三光学部材シート体F3Sを、第三光学部材シート体F3Sの長手方向に沿って巻き出すロール保持部19a(巻き出し部)と、第三原反ロールR3から巻き出した第三光学部材シート体F3Sを第三貼合装置18の貼合位置まで所定のシート搬送経路に沿って案内するべく第三光学部材シート体F3SのセパレータシートSS側を巻きかける単数又は複数(図では一つのみ示す)のガイドローラ19bと、シート搬送経路上の第三光学部材シート体F3SにセパレータシートSSを残したハーフカットを施す切断装置19c(カット部)と、ハーフカットを施した第三光学部材シート体F3SのセパレータシートSS側を鋭角に巻きかけてセパレータシートSSから第三光学部材F13を分離させつつ第三光学部材F13を貼合位置に供給するナイフエッジ19dと、ナイフエッジ19dを経て単独となったセパレータシートSSを巻き取るセパレータ回収部19eとを有する。   The transport device 19 holds the third original roll R3 and rolls out the third optical member sheet F3S from the third original roll R3 along the longitudinal direction of the third optical member sheet F3S. The third optical member 19a (unwinding part) and the third optical member sheet F3S unwound from the third original fabric roll R3 are guided to the bonding position of the third bonding apparatus 18 along the predetermined sheet conveying path. Single or plural (only one is shown in the figure) guide rollers 19b that wind the separator sheet SS side of the optical member sheet body F3S, and a half that leaves the separator sheet SS on the third optical member sheet body F3S on the sheet conveyance path A separator 19c (cut part) that performs cutting and the separator sheet SS side of the third optical member sheet F3S that has been half-cut are wound at an acute angle to separate the separator sheet A knife edge 19d for supplying the third optical member F13 to the bonding position while separating the third optical member F13 from the sheet SS, and a separator collecting portion 19e for winding the separator sheet SS that has become independent through the knife edge 19d. Have.
搬送装置19の始点に位置するロール保持部19aと搬送装置19の終点に位置するセパレータ回収部19eとは、例えば互いに同期して駆動する。これにより、ロール保持部19aが第三光学部材シート体F3Sを、第三光学部材シート体F3Sの搬送方向へ巻き出しつつ、セパレータ回収部19eがナイフエッジ19dを経て単独となったセパレータシートSSを巻き取る。   The roll holding unit 19a positioned at the start point of the transport device 19 and the separator recovery unit 19e positioned at the end point of the transport device 19 are driven in synchronization with each other, for example. As a result, the separator holding unit 19a unwinds the third optical member sheet body F3S in the conveying direction of the third optical member sheet body F3S, and the separator recovery unit 19e becomes a single separator sheet SS via the knife edge 19d. Wind up.
切断装置19cは、第三光学部材シート体F3Sが所定長さ巻き出された際、第三光学部材シート体F3Sを、第三光学部材シート体F3Sの長手方向(巻き出し方向)と直交する幅方向の全幅にわたってセパレータシートSSを残して切断する(すなわち第三光学部材シートF3のみを切断する)。切断装置19cは、第三光学部材シート体F3Sの搬送中に働くテンションによってセパレータシートSSが破断しないように切断刃の進退位置を調整する。   When the third optical member sheet body F3S is unwound by a predetermined length, the cutting device 19c has a width orthogonal to the longitudinal direction (unwinding direction) of the third optical member sheet body F3S. The separator sheet SS is cut over the entire width in the direction (that is, only the third optical member sheet F3 is cut). The cutting device 19c adjusts the advancing / retreating position of the cutting blade so that the separator sheet SS is not broken by the tension acting during the conveyance of the third optical member sheet body F3S.
前記切断後の第三光学部材シート体F3Sには、第三光学部材シート体F3Sの幅方向の全幅にわたるカットラインが形成される。
ここで、ナイフエッジ19dの先端部近傍であって第三貼合装置18の貼合位置近傍のパネル搬送上流側の部位には、当該部位における第三光学部材F13の巻き出し方向下流側の切断端を検出する第一検出カメラ22が設けられる。第一検出カメラ22の検出情報は制御装置20に送られる。制御装置20は、例えば第一検出カメラ22が第三光学部材F13の下流側端を検出した時点で、搬送装置19を一旦停止させる。その後、第一検出カメラ22が第二片面貼合パネルP12の下流側端を検出した時点で、制御装置20が搬送装置19を駆動させ、第二片面貼合パネルP12と第三光学部材F13とを同期させて第三貼合装置18の貼合位置に導入可能とする。
In the third optical member sheet body F3S after the cutting, a cut line that extends over the entire width in the width direction of the third optical member sheet body F3S is formed.
Here, in the vicinity of the tip end portion of the knife edge 19d and in the vicinity of the bonding position of the third bonding device 18, the upstream side of the panel conveyance is cut at the downstream side in the unwinding direction of the third optical member F13. A first detection camera 22 for detecting the end is provided. The detection information of the first detection camera 22 is sent to the control device 20. For example, when the first detection camera 22 detects the downstream end of the third optical member F13, the control device 20 temporarily stops the transport device 19. Then, when the 1st detection camera 22 detects the downstream end of the 2nd single-sided bonding panel P12, the control apparatus 20 drives the conveying apparatus 19, and the 2nd single-sided bonding panel P12, the 3rd optical member F13, Can be synchronized and introduced into the bonding position of the third bonding apparatus 18.
一方、第一検出カメラ22よりも巻き出し方向上流側であって切断装置19cよりも第三光学部材F13一つ分だけ前記巻き出し方向下流側の部位には、同じく第三光学部材F13の巻き出し方向下流側の切断端を検出する第二検出カメラ23(検出部)が設けられる。第二検出カメラ23の検出情報も制御装置20に送られる。制御装置20は、例えば切断装置19cによる第三光学部材シートF3の切断後にこれを巻き出し、その切断端(第三光学部材シートF3の最上流側のカットライン)を第二検出カメラ23が検出した時点で、搬送装置19を一旦停止させる。このとき、切断装置19cによる第三光学部材シートF3のカットがなされる。すなわち、第二検出カメラ23による検出位置(第三光学部材シートF3における第二検出カメラ23の光軸延長位置に相当)と切断装置19cによるカット位置(第三光学部材シートF3における切断装置19cの切断刃進退位置に相当)との間のシート搬送経路に沿う距離が、第三光学部材F13の長さに相当する。   On the other hand, the third optical member F13 is similarly wound on the upstream side in the unwinding direction from the first detection camera 22 and downstream of the cutting device 19c by one third optical member F13 in the unwinding direction. A second detection camera 23 (detection unit) that detects a cut end on the downstream side in the ejection direction is provided. Detection information of the second detection camera 23 is also sent to the control device 20. The control device 20 unwinds the third optical member sheet F3 by the cutting device 19c, for example, and the second detection camera 23 detects the cut end (the cut line on the most upstream side of the third optical member sheet F3). At that time, the conveying device 19 is temporarily stopped. At this time, the third optical member sheet F3 is cut by the cutting device 19c. That is, the detection position by the second detection camera 23 (corresponding to the optical axis extension position of the second detection camera 23 in the third optical member sheet F3) and the cut position by the cutting device 19c (of the cutting device 19c in the third optical member sheet F3). (Corresponding to the cutting blade advance / retreat position) along the sheet conveyance path corresponds to the length of the third optical member F13.
前記カットラインは、例えば同一サイズの液晶パネルPに貼合する第三光学部材F13を切り出す場合には、第三光学部材シート体F3Sの長手方向で等間隔に形成される。第三光学部材シートF3は、複数のカットラインによって長手方向で複数の区画に分けられ、この第三光学部材シートF3における長手方向で隣り合う一対のカットラインに挟まれる区画が、それぞれ第三光学部材F13とされる。第三光学部材F13の長さは、本実施形態では表示領域P4の全長以上で液晶パネルPの全長以下とされる。   For example, when the third optical member F13 to be bonded to the liquid crystal panel P of the same size is cut out, the cut lines are formed at equal intervals in the longitudinal direction of the third optical member sheet body F3S. The third optical member sheet F3 is divided into a plurality of sections in the longitudinal direction by a plurality of cut lines, and the sections sandwiched between a pair of cut lines adjacent in the longitudinal direction in the third optical member sheet F3 are respectively third optical members. The member is F13. In the present embodiment, the length of the third optical member F13 is not less than the entire length of the display region P4 and not more than the entire length of the liquid crystal panel P.
また、切断装置19cは、第三光学部材シート体F3Sのシート搬送経路に沿って移動可能とされる。この移動により、第二検出カメラ23による検出位置と切断装置19cによるカット位置との間のシート搬送経路に沿う距離が変動する。切断装置19cの移動は制御装置20により制御され、例えば切断装置19cによる第三光学部材シートF3の切断後にこれを第三光学部材F13一つ分だけ巻き出した際、その切断端が所定位置からずれる場合には、このずれを切断装置19cの移動により補正する。   The cutting device 19c is movable along the sheet conveyance path of the third optical member sheet body F3S. By this movement, the distance along the sheet conveyance path between the detection position by the second detection camera 23 and the cutting position by the cutting device 19c varies. The movement of the cutting device 19c is controlled by the control device 20. For example, when the third optical member sheet F3 is unwound by the cutting device 19c after the third optical member sheet F3 is cut, the cut end is moved from a predetermined position. In the case of deviation, this deviation is corrected by the movement of the cutting device 19c.
なお、切断装置19cの移動により長さの異なる第三光学部材F13のカットに対応することも可能である。また、切断装置19c及び第二検出カメラ23の少なくとも一方をシート搬送方向で移動させることで、前記補正や第三光学部材F13の長さ変更を行う構成としてもよい。また、切断装置19cと第二検出カメラ23とは互いに近接するが、切断装置19cの移動等に伴う第二検出カメラ23の振動を防止するために、これらは別フレームで支持することが好ましい。   It is also possible to cope with the cutting of the third optical member F13 having a different length by the movement of the cutting device 19c. In addition, the correction and the length change of the third optical member F13 may be performed by moving at least one of the cutting device 19c and the second detection camera 23 in the sheet conveyance direction. Further, the cutting device 19c and the second detection camera 23 are close to each other. However, in order to prevent the vibration of the second detection camera 23 accompanying the movement of the cutting device 19c or the like, it is preferable to support them with separate frames.
ナイフエッジ19dは、ローラコンベヤ5の下方に配置されて第三光学部材シート体F3Sの幅方向で少なくともその全幅にわたって延在する。ナイフエッジ19dは、ハーフカット後の第三光学部材シート体F3SのセパレータシートSS側に摺接するようにこれを鋭角に巻きかける。   The knife edge 19d is disposed below the roller conveyor 5 and extends over at least the entire width in the width direction of the third optical member sheet body F3S. The knife edge 19d is wound at an acute angle so as to be in sliding contact with the separator sheet SS side of the third optical member sheet body F3S after the half cut.
第三光学部材シート体F3Sは、ナイフエッジ19dで鋭角に折り返す際、セパレータシートSSから第三光学部材F13を分離させる。ナイフエッジ19dは、挟圧ロール21のパネル搬送下流側に近接して配置される。ナイフエッジ19dによりセパレータシートSSから分離した第三光学部材F13は、ローラコンベヤ5が搬送する液晶パネルPの下面に重なりつつ、挟圧ロール21の一対の貼合ローラ間に導入される。   The third optical member sheet body F3S separates the third optical member F13 from the separator sheet SS when it is folded at an acute angle by the knife edge 19d. The knife edge 19d is disposed close to the panel conveyance downstream side of the pinching roll 21. The third optical member F13 separated from the separator sheet SS by the knife edge 19d is introduced between the pair of bonding rollers of the pinching roll 21 while overlapping the lower surface of the liquid crystal panel P conveyed by the roller conveyor 5.
挟圧ロール21は、互いに軸方向を平行にして配置された一対の貼合ローラを有する。
一対の貼合ローラ間には所定の間隙が形成され、この間隙内が第三貼合装置18の貼合位置となる。前記間隙内には、第二片面貼合パネルP12及び第三光学部材F13が重なり合って導入される。これら第二片面貼合パネルP12及び第三光学部材F13が、前記貼合ローラ間で挟圧されつつパネル搬送下流側に送り出される。これにより、第二片面貼合パネルP12に第三光学部材F13を貼合した両面貼合パネルP13が形成される(図7参照)。
The pinching roll 21 has a pair of laminating rollers arranged with their axial directions parallel to each other.
A predetermined gap is formed between the pair of bonding rollers, and the gap is the bonding position of the third bonding device 18. In the gap, the second single-sided bonding panel P12 and the third optical member F13 are introduced overlapping each other. These 2nd single-sided bonding panels P12 and the 3rd optical member F13 are sent out to a panel conveyance downstream, being pinched between the said bonding rollers. Thereby, the double-sided bonding panel P13 which bonded the 3rd optical member F13 to the 2nd single-sided bonding panel P12 is formed (refer FIG. 7).
両面貼合パネルP13は、不図示の欠陥検査装置を経て欠陥(貼合不良等)の有無が検査された後、下流工程に搬送されて他の処理がなされる。   After the double-sided bonding panel P13 is inspected for defects (such as poor bonding) through a defect inspection device (not shown), it is transported to the downstream process and subjected to other processes.
ここで、一般に長尺の光学フィルム(各光学部材シートF1,F2,F3に相当)は、二色性色素で染色した樹脂フィルムを一軸延伸させて製造されており、光学フィルムの光学軸の方向は樹脂フィルムの延伸方向と概ね一致する。しかし、光学フィルムの光学軸は、光学フィルム全体で均一ではなく、光学フィルムの幅方向で若干ばらついている。   Here, in general, a long optical film (corresponding to each optical member sheet F1, F2, F3) is manufactured by uniaxially stretching a resin film dyed with a dichroic dye, and the direction of the optical axis of the optical film Generally coincides with the stretching direction of the resin film. However, the optical axis of the optical film is not uniform throughout the optical film, but varies slightly in the width direction of the optical film.
このため、光学フィルムにその幅方向で複数の光学表示部品を貼合するような場合、光学フィルムの光学軸方向に合わせて光学表示部品のアライメントを行うことが望ましい。
これは、光学表示デバイス単位の光学軸のバラツキを抑えて精彩やコントラストを高めるという点で有効である。
For this reason, when bonding a some optical display component to the optical film in the width direction, it is desirable to align an optical display component according to the optical axis direction of an optical film.
This is effective in that the variation in the optical axis of each optical display device is suppressed and the color and contrast are enhanced.
偏光フィルムとしての光学フィルムは、一方向に振動する光以外の光を遮断するために、例えばヨウ素や二色性染料等により染色されている。なお、光学フィルムに剥離フィルムや保護フィルムがさらに積層されてもよい。   An optical film as a polarizing film is dyed with, for example, iodine or a dichroic dye in order to block light other than light that vibrates in one direction. In addition, a peeling film and a protective film may be further laminated | stacked on the optical film.
光学フィルムの光学軸方向を検査する検査装置は、光学フィルムの表面及び裏面のうち一方の面に近い位置に配置された光源と、光学フィルムの表面及び裏面のうち他方の面に近い位置に配置され、光源とは反対側に配置された検光子とを有する。検光子は、光源から照射されて光学フィルムを透過した光を受光し、この光の強度を検出することで、光学フィルムの光学軸を検出する。検光子は、例えば光学フィルムの幅方向で移動可能であり、光学フィルムの幅方向の任意箇所(使用条件に応じて選択された箇所)で光学軸を検査可能である。   The inspection device for inspecting the optical axis direction of the optical film is disposed at a position near the other surface of the front and back surfaces of the optical film, and a light source disposed at a position near one of the front and back surfaces of the optical film. And an analyzer disposed on the opposite side of the light source. The analyzer receives the light irradiated from the light source and transmitted through the optical film, and detects the optical axis of the optical film by detecting the intensity of this light. The analyzer can be moved in the width direction of the optical film, for example, and the optical axis can be inspected at an arbitrary position in the width direction of the optical film (a position selected according to use conditions).
本実施形態の場合、前記検査装置で得た各光学部材シートF1,F2,F3の光学軸方向の検査データは、各光学部材シートF1,F2,F3の長手方向位置と幅方向位置とに関連付けられて制御装置20のメモリに記憶される。この検査後に各光学部材シートF1,F2,F3が巻き取られて各原反ロールR1,R2,R3をそれぞれ形成する。以下、各光学部材シートF1,F2,F3を光学部材シートFX、各光学部材シートF1,F2,F3に貼合される液晶パネルP及び各片面貼合パネルP11,P12を光学表示部品PXと総称することがある。   In the case of this embodiment, the inspection data in the optical axis direction of each optical member sheet F1, F2, F3 obtained by the inspection apparatus is associated with the longitudinal direction position and the width direction position of each optical member sheet F1, F2, F3. And stored in the memory of the control device 20. After this inspection, the optical member sheets F1, F2, and F3 are wound up to form the original rolls R1, R2, and R3, respectively. Hereinafter, the optical member sheets F1, F2, and F3 are collectively referred to as the optical member sheet FX, the liquid crystal panel P that is bonded to the optical member sheets F1, F2, and F3, and the single-sided bonding panels P11 and P12 are collectively referred to as the optical display component PX. There are things to do.
ここで、光学部材シートFXを構成する偏光子フィルムは、例えば二色性色素で染色したPVAフィルムを一軸延伸して形成されるが、延伸する際のPVAフィルムの厚さのムラや二色性色素の染色ムラ等に起因して、光学部材シートFXの幅方向内側と幅方向外側とで光学軸方向の相違が生じる傾向にある。   Here, the polarizer film constituting the optical member sheet FX is formed by, for example, uniaxially stretching a PVA film dyed with a dichroic dye, but the PVA film has uneven thickness or dichroism when stretched. Due to uneven coloring of the dye, etc., there is a tendency that a difference in the optical axis direction occurs between the inner side in the width direction and the outer side in the width direction of the optical member sheet FX.
そこで、本実施形態では、制御装置20に予め記憶した光学部材シートFXの各部における光学軸の面内分布の検査データに基づき、これらに貼合する光学表示部品PXのアライメントを行った上で、光学部材シートFXに光学表示部品PXを貼合している。   Therefore, in the present embodiment, based on the inspection data of the in-plane distribution of the optical axis in each part of the optical member sheet FX stored in advance in the control device 20, the alignment of the optical display component PX to be bonded to these is performed. The optical display component PX is bonded to the optical member sheet FX.
具体的には、光学部材シートFXにおける光学表示部品PXを貼合する部位の面内において、例えば所定の基準軸(長手方向軸等)に対する角度が最大の光学軸と最小の光学軸とを見出し、これら各光学軸がなす角を二等分する軸を当該部位の平均的な光学軸として、この軸を基準に光学表示部品PXのアライメントを行っている。   Specifically, for example, the optical axis having the maximum angle and the minimum optical axis with respect to a predetermined reference axis (longitudinal axis or the like) is found in the plane of the portion where the optical display component PX is bonded to the optical member sheet FX. The optical display component PX is aligned on the basis of the axis that bisects the angle formed by these optical axes as an average optical axis of the part.
これにより、光学部材シートFXの幅方向で異なる位置に光学表示部品PXを貼合する場合にも、光学表示部品PXの基準位置に対する光学部材シートFXの光学軸方向のバラツキを抑制でき、光学軸公差をほぼ0°(許容公差は±0.25°)にすることができる。   Accordingly, even when the optical display component PX is bonded to a different position in the width direction of the optical member sheet FX, the variation in the optical axis direction of the optical member sheet FX with respect to the reference position of the optical display component PX can be suppressed. The tolerance can be approximately 0 ° (allowable tolerance is ± 0.25 °).
なお、光学部材シートFXを巻き出しつつ光学軸方向を検出し、この検出データに基づき光学表示部品PXのアライメントを行うようにしてもよい。また、前述した種々のアライメント手法は、光学部材シートFXの光学軸方向が0°及び90°の場合に限らず、光学軸方向が任意の角度(光学表示部品の目的に応じた角度)に設定されている場合にも適用できる。   Note that the optical axis direction may be detected while the optical member sheet FX is unwound, and the optical display component PX may be aligned based on the detection data. The various alignment methods described above are not limited to the case where the optical axis direction of the optical member sheet FX is 0 ° and 90 °, and the optical axis direction is set to an arbitrary angle (an angle corresponding to the purpose of the optical display component). It is also applicable when
また、図3は比較的広い幅を有する光学部材シートFXにその幅方向で三つの光学表示部品PXを並べて貼合する例を示す。本発明は、図3に示す例に限らず、二つ以下又は四つ以上の光学表示部品PXを光学部材シートFXの幅方向で並べて貼合する構成が採用されてもよいし、比較的幅の狭い光学部材シートFXを幅方向に複数並べてこれらのそれぞれに光学表示部品PXを貼合する構成が採用されてもよい。   FIG. 3 shows an example in which three optical display components PX are aligned and bonded to an optical member sheet FX having a relatively wide width in the width direction. The present invention is not limited to the example shown in FIG. 3, and a configuration in which two or less or four or more optical display components PX are aligned and bonded in the width direction of the optical member sheet FX may be employed, and may be relatively wide. A configuration may be adopted in which a plurality of narrow optical member sheets FX are arranged in the width direction and the optical display component PX is bonded to each of them.
図4を参照し、液晶パネルPは、例えばTFT基板からなる長方形状の第一基板P1と、第一基板P1に対向して配置される同じく長方形状の第二基板P2と、第一基板P1と第二基板P2との間に封入される液晶層P3とを有する。なお、図示都合上、断面図の各層のハッチングを略すことがある。   Referring to FIG. 4, the liquid crystal panel P includes a rectangular first substrate P1 made of, for example, a TFT substrate, a second rectangular substrate P2 disposed opposite to the first substrate P1, and a first substrate P1. And a liquid crystal layer P3 sealed between the second substrate P2. For convenience of illustration, hatching of each layer in the cross-sectional view may be omitted.
図6を参照し、第一基板P1は、第一基板P1の外周縁の三辺を第二基板P2の対応する三辺に沿わせると共に、外周縁の残りの一辺を第二基板P2の対応する一辺よりも外側に張り出させる。これにより、第一基板P1の前記一辺側に第二基板P2よりも外側に張り出す電気部品取り付け部P5が設けられる。   Referring to FIG. 6, the first substrate P1 has three sides of the outer periphery of the first substrate P1 along the corresponding three sides of the second substrate P2, and the other one side of the outer periphery corresponds to the second substrate P2. Bulge outward from one side. As a result, an electrical component attachment portion P5 is provided on the one side of the first substrate P1 so as to project outward from the second substrate P2.
図5を参照し、第二切断装置16は、表示領域P4の外周縁をカメラ16a等の検出部で検出しつつ、表示領域P4の外周縁等に沿って第一及び第二光学部材シートF1,F2を切断する。表示領域P4の外側には、第一及び第二基板P1,P2を接合するシール剤等を配置する所定幅の額縁部Gが設けられ、この額縁部Gの幅内で第二切断装置16によるレーザーカットがなされる。   Referring to FIG. 5, the second cutting device 16 detects the outer peripheral edge of the display region P4 with a detection unit such as a camera 16a, and the first and second optical member sheets F1 along the outer peripheral edge of the display region P4. , F2 is cut. Outside the display region P4, a frame portion G having a predetermined width for arranging a sealant or the like for joining the first and second substrates P1 and P2 is provided. The frame is cut by the second cutting device 16 within the width of the frame portion G. Laser cut is made.
図9に示すように、樹脂製の光学部材シートFXを単独でレーザーカットすると、光学部材シートFXの切断端tが熱変形により膨れたり波打ったりすることがある。このため、レーザーカット後の光学部材シートFXを光学表示部品PXに貼合する場合には、光学部材シートFXにエア混入や歪み等の貼合不良が生じ易い。   As shown in FIG. 9, when the resin optical member sheet FX is laser-cut alone, the cut end t of the optical member sheet FX may be swollen or waved due to thermal deformation. For this reason, when the optical member sheet FX after laser cutting is bonded to the optical display component PX, poor bonding such as air mixing and distortion is likely to occur in the optical member sheet FX.
一方、図8に示すように、光学部材シートFXを液晶パネルPに貼合した後に光学部材シートFXをレーザーカットする本実施形態では、光学部材シートFXの切断端tが液晶パネルPのガラス面にバックアップされる。このため、光学部材シートFXの切断端tの膨れや波打ち等が生じず、かつ液晶パネルPへ光学部材シートFXを貼合した後であることから前記貼合不良も生じ得ない。   On the other hand, as shown in FIG. 8, in this embodiment in which the optical member sheet FX is laser-cut after the optical member sheet FX is bonded to the liquid crystal panel P, the cut end t of the optical member sheet FX is the glass surface of the liquid crystal panel P. Is backed up. For this reason, since the swelling of the cut end t of the optical member sheet FX, undulation or the like does not occur, and the optical member sheet FX is bonded to the liquid crystal panel P, the bonding failure cannot occur.
液晶パネルP上で光学部材シートFXをカットするような場合、レーザー加工機の切断線の振れ幅(公差)は切断刃の切断線の振れ幅よりも小さい。したがって本実施形態では、切断刃を用いて光学部材シートFXを切断する場合と比べて、前記額縁部Gの幅を狭めることが可能であり、液晶パネルPの小型化及び(又は)表示領域P4の大型化が可能である。このような光学部材シートは、近年のスマートフォンやタブレット端末のように、筐体のサイズが制限される中で表示画面の拡大が要求される高機能モバイルへの適用に有効である。   When the optical member sheet FX is cut on the liquid crystal panel P, the deflection width (tolerance) of the cutting line of the laser processing machine is smaller than the deflection width of the cutting line of the cutting blade. Therefore, in the present embodiment, it is possible to reduce the width of the frame portion G as compared with the case where the optical member sheet FX is cut using a cutting blade, and the liquid crystal panel P can be reduced in size and / or the display area P4. Can be made larger. Such an optical member sheet is effective for application to a high-function mobile device that requires an enlargement of the display screen while the size of the housing is limited, such as a recent smartphone or tablet terminal.
ここで、光学部材シートFXを液晶パネルPの表示領域P4に整合するシート片にカットした後に別ラインに搬送して液晶パネルPに貼合する場合、前記シート片及び液晶パネルPそれぞれの寸法公差、並びにこれらの相対貼合位置の寸法公差が重なるため、液晶パネルPの額縁部Gの幅を狭めることが困難になる(表示エリアの拡大が困難になる)。   Here, when the optical member sheet FX is cut into a sheet piece aligned with the display region P4 of the liquid crystal panel P and then transported to another line and bonded to the liquid crystal panel P, the dimensional tolerances of the sheet piece and the liquid crystal panel P respectively. In addition, since the dimensional tolerances of these relative bonding positions overlap, it is difficult to reduce the width of the frame portion G of the liquid crystal panel P (it is difficult to enlarge the display area).
一方、光学部材シートFXを液晶パネルPに貼合した後に表示領域P4に合わせてカットする場合、切断線の振れ公差のみを考慮すればよく、額縁部Gの幅の公差を小さくすることができる(±0.1mm以下)。この点においても、液晶パネルPの額縁部Gの幅を狭めることができる(表示エリアの拡大が可能となる)。   On the other hand, when the optical member sheet FX is bonded to the liquid crystal panel P and then cut in accordance with the display region P4, only the runout tolerance of the cutting line needs to be considered, and the width tolerance of the frame portion G can be reduced. (± 0.1 mm or less). Also in this respect, the width of the frame part G of the liquid crystal panel P can be reduced (the display area can be enlarged).
さらに、液晶パネルP上の光学部材シートFXを刃物ではなくレーザーでカットすることで、切断時の力が液晶パネルPに入力されず、液晶パネルPの基板の端縁にクラックや欠けが生じ難くなり、ヒートサイクル等に対する耐久性が向上する。同様に、液晶パネルPに非接触であるため、電気部品取り付け部P5に対するダメージも少ない。   Further, by cutting the optical member sheet FX on the liquid crystal panel P with a laser instead of a blade, the cutting force is not input to the liquid crystal panel P, and cracks and chips are hardly generated at the edge of the substrate of the liquid crystal panel P. Thus, durability against heat cycle and the like is improved. Similarly, since there is no contact with the liquid crystal panel P, there is little damage to the electrical component mounting portion P5.
また、第三貼合装置18は、表示領域P4に対応する幅を有する帯状の第三光学部材シートF3を所定長さにカットして第三光学部材F13を形成する。第三貼合装置18は、この第三光学部材F13をセパレータシートSSと共に搬送しつつ、前記カットを行うライン内で第二片面貼合パネルP12に貼合する。このため、表示領域P4に合わせて加工した偏光板を別ラインに搬送するような場合と比べて、第三光学部材F13の寸法バラツキや貼合バラツキの影響が抑えられる。   Moreover, the 3rd bonding apparatus 18 cuts the strip | belt-shaped 3rd optical member sheet | seat F3 which has the width | variety corresponding to the display area P4 to predetermined length, and forms the 3rd optical member F13. The 3rd bonding apparatus 18 is bonded to the 2nd single-sided bonding panel P12 within the line which performs the said cut, conveying this 3rd optical member F13 with separator sheet SS. For this reason, compared with the case where the polarizing plate processed according to the display area P4 is conveyed to another line, the influence of the dimensional variation of the 3rd optical member F13 and bonding variation is suppressed.
図6に示すように、光学部材シートFX(図6では第二光学部材シートF2)をレーザーカットする場合、例えば表示領域P4の一長辺の延長上にレーザーカットの始点pt1を設定し、この始点pt1からまず前記一長辺の切断を開始する。レーザーカットの終点pt2は、レーザーが表示領域P4を一周して表示領域P4の始点側の短辺の延長上に至る位置に設定する。始点pt1及び終点pt2は、光学部材シートFXの余剰部分に所定の接続代を残し、光学部材シートFXを巻き取る際の張力に耐え得るように設定される。   As shown in FIG. 6, when laser cutting the optical member sheet FX (second optical member sheet F2 in FIG. 6), for example, a laser cut start point pt1 is set on the extension of one long side of the display region P4, and this First, the cutting of the one long side is started from the starting point pt1. The end point pt2 of the laser cut is set at a position where the laser goes around the display area P4 and reaches the extension of the short side on the start point side of the display area P4. The start point pt1 and the end point pt2 are set so as to be able to withstand the tension when the optical member sheet FX is wound, leaving a predetermined connection allowance in the surplus portion of the optical member sheet FX.
以上説明したように、上記実施形態における光学表示デバイスの生産システムは、液晶パネルPに光学部材F11,F12,F13を貼合してなる光学表示デバイスの生産システムの一部をなすフィルム貼合システム1において、ローラコンベヤ5上を搬送される複数の光学表示部品PXに対し、光学表示部品PXの搬送方向と直交する部品幅方向で液晶パネルPの表示領域P4の幅よりも大きい幅を有する帯状の光学部材シートF1,F2を、原反ロールR1,R2から巻き出しつつ、第一光学部材シートF1に第二光学部材シートF2及び複数の液晶パネルPの第一面(表面及び裏面のうち一方の面)を順に貼り合わせて第二貼合シートF22とする貼合装置12,15と、前記表示領域P4に対向する前記光学部材シートF1,F2の対向部分と前記対向部分の外側に位置する余剰部分とを切り離し、前記光学部材シートF1,F2から前記表示領域P4に対応する大きさを有する光学部材F11,F12を切り出すことで、前記第二貼合シートF22から単一の前記液晶パネルP及びこれに重なる前記光学部材F11,F12を含む第二片面貼合パネルP12を切り出す第二切断装置16と、ローラコンベヤ5上を搬送される複数の前記第二片面貼合パネルP12に対し、前記部品幅方向で前記表示領域P4に対応する幅を有する帯状の第三光学部材シートF3を、第三原反ロールR3からセパレータシートSSと共に巻き出し、この第三光学部材シートF3に、前記表示領域P4に対応する長さで第三光学部材シートF3を巻き出す毎に幅方向に沿うカットを施し、前記表示領域P4に対応する大きさを有する第三光学部材F13とした後、前記セパレータシートSSをキャリアとして複数の前記第三光学部材F13を搬送しつつ、前記第三光学部材F13を前記第二片面貼合パネルP12における前記液晶パネルPの第二面(第一面とは反対の面、表面及び裏面のうち他方の面)に貼り合わせる第三貼合装置18とを備える。   As described above, the optical display device production system in the above embodiment is a film bonding system that forms a part of the optical display device production system in which the optical members F11, F12, and F13 are bonded to the liquid crystal panel P. 1, for a plurality of optical display components PX conveyed on the roller conveyor 5, a strip shape having a width larger than the width of the display area P <b> 4 of the liquid crystal panel P in the component width direction orthogonal to the conveyance direction of the optical display components PX While the optical member sheets F1 and F2 are unwound from the original fabric rolls R1 and R2, the first optical member sheet F1 and the second optical member sheet F2 and the first surface of the plurality of liquid crystal panels P (one of the front surface and the back surface). Of the optical member sheets F1 and F2 facing the display region P4, and the bonding devices 12 and 15 that are bonded in order to form the second bonding sheet F22. The second portion is cut off by cutting off the direction portion and the excess portion located outside the facing portion and cutting out the optical members F11 and F12 having a size corresponding to the display area P4 from the optical member sheets F1 and F2. A second cutting device 16 that cuts out the single liquid crystal panel P and the second single-sided bonding panel P12 including the optical members F11 and F12 overlapping with the liquid crystal panel P from the sheet F22; The strip-shaped third optical member sheet F3 having a width corresponding to the display area P4 in the component width direction is unwound from the third original fabric roll R3 together with the separator sheet SS to the second single-sided bonding panel P12. Each time the third optical member sheet F3 is unwound at a length corresponding to the display area P4, the third optical member sheet F3 is cut along the width direction, After making the third optical member F13 having a size corresponding to the indicated region P4, the third optical member F13 is transferred to the second single-sided surface while transporting the plurality of third optical members F13 using the separator sheet SS as a carrier. The 3rd bonding apparatus 18 bonded to the 2nd surface (The surface opposite to a 1st surface, the other surface among a surface and a back surface) of the said liquid crystal panel P in the bonding panel P12 is provided.
この構成によれば、表示領域P4に対応する幅を有する帯状の第三光学部材シートF3を所定長さにカットして第三光学部材F13が形成され、この第三光学部材F13を、第三光学部材シートF3と共に巻き出したセパレータシートSSをキャリアとして搬送しつつ、前記カットを行うライン内で液晶パネルPに第三光学部材F13が貼合される。このため、表示領域P4に合わせて加工した偏光板を別ラインに搬送するような場合と比べて、第三光学部材F13の寸法バラツキや貼合バラツキを抑え、表示領域P4周辺の額縁部Gを縮小して表示エリアの拡大及び機器の小型化を図ることができる。
また、液晶パネルPへの貼合後の光学部材シートF1,F2のカットと、セパレータシートSSを残したハーフカット後の第三光学部材シートF3の貼合とを組み合わせることで、額縁部Gの縮小とタクトタイムの短縮とを図ることができる。
According to this configuration, the third optical member F13 is formed by cutting the band-shaped third optical member sheet F3 having a width corresponding to the display region P4 into a predetermined length. The third optical member F13 is bonded to the liquid crystal panel P in the line for performing the cut while conveying the separator sheet SS unwound together with the optical member sheet F3 as a carrier. For this reason, compared with the case where the polarizing plate processed according to the display region P4 is conveyed to another line, the dimensional variation and the bonding variation of the third optical member F13 are suppressed, and the frame portion G around the display region P4 is reduced. By reducing the size, the display area can be enlarged and the device can be downsized.
Moreover, by combining the cut of the optical member sheets F1 and F2 after bonding to the liquid crystal panel P and the bonding of the third optical member sheet F3 after half-cut leaving the separator sheet SS, Reduction and reduction of tact time can be achieved.
また、上記光学表示デバイスの生産システムは、前記第三貼合装置18が、前記第三光学部材シートF3を前記セパレータシートSSと共に巻き出すロール保持部19aと、前記第三光学部材シートF3にカットを施して前記第三光学部材F13とする切断装置19cと、前記第三光学部材シートF3にカットを施すカット位置よりも、前記第三光学部材シートF3の巻き出し方向で前記第三光学部材F13一つ分に対応する距離だけ下流側に離間した位置で、前記第三光学部材シートF3に前記カットにより形成されたカットラインを検出する第二検出カメラ23と、前記カット位置から下流側に前記第三光学部材F13一つ分の距離で離間した検出位置で前記カットラインを検出したときに、前記カットラインの位置に応じて前記カット位置と前記検出位置との間の距離を調整する制御装置20とを備える。   Further, in the production system for the optical display device, the third bonding device 18 cuts the third optical member sheet F3 together with the separator sheet SS and the third optical member sheet F3. The third optical member F13 in the unwinding direction of the third optical member sheet F3 than the cutting device 19c that forms the third optical member F13 and the cutting position for cutting the third optical member sheet F3. A second detection camera 23 for detecting a cut line formed by the cut on the third optical member sheet F3 at a position spaced downstream by a distance corresponding to one; the downstream from the cut position; When the cut line is detected at a detection position separated by a distance corresponding to one third optical member F13, the cut is performed according to the position of the cut line. And a control unit 20 for adjusting the distance between the detection position and location.
この構成によれば、第三光学部材シートF3のカット位置よりも第三光学部材F13一つ分だけ下流側に位置する第二検出カメラ23によって、前記第三光学部材F13の巻き出し方向下流側端を検出したときに、切断装置19cによって第三光学部材シートF3にカットを施すことが可能となり、規定長さの第三光学部材F13を得ることができる。また、第三光学部材シートF3の巻き出し量に誤差が生じても、第二検出カメラ23の検出情報に基づく切断装置19cの相対移動により前記誤差を補正(吸収)することが可能となる。このため、第三光学部材F13の長さの精度を確保することができ、かつ長さの異なる第三光学部材F13の切り出しにも対応することができる。   According to this configuration, the third optical member F13 is unwound in the unwinding direction of the third optical member F13 by the second detection camera 23 that is located downstream from the cutting position of the third optical member sheet F3 by one third optical member F13. When the edge is detected, the third optical member sheet F3 can be cut by the cutting device 19c, and the third optical member F13 having a specified length can be obtained. Even if an error occurs in the unwinding amount of the third optical member sheet F3, the error can be corrected (absorbed) by the relative movement of the cutting device 19c based on the detection information of the second detection camera 23. For this reason, the precision of the length of the 3rd optical member F13 can be ensured, and it can respond also to cutting out of the 3rd optical member F13 from which length differs.
ここで、上記実施形態における光学表示デバイスの生産方法は、ローラコンベヤ5上を搬送される複数の光学表示部品PXに対し、光学表示部品PXの搬送方向と直交する部品幅方向で液晶パネルPの表示領域P4の幅よりも大きい幅を有する帯状の光学部材シートF1,F2を、原反ロールR1,R2から巻き出しつつ、第一光学部材シートF1に第二光学部材シートF2及び複数の液晶パネルPの第一面を順に貼り合わせて第二貼合シートF22を形成し、前記表示領域P4に対向する前記光学部材シートF1,F2の対向部分と前記対向部分の外側に位置する余剰部分とを切り離し、前記光学部材シートF1,F2から前記表示領域P4に対応する大きさを有する光学部材F11,F12を切り出すことで、前記第二貼合シートF22から単一の前記液晶パネルP及びこれに重なる前記光学部材F11,F12を含む第二片面貼合パネルP12を切り出し、ローラコンベヤ5上を搬送される複数の前記第二片面貼合パネルP12に対し、前記部品幅方向で前記表示領域P4に対応する幅を有する帯状の第三光学部材シートF3を、第三原反ロールR3からセパレータシートSSと共に巻き出し、この第三光学部材シートF3に、前記表示領域P4に対応する長さで第三光学部材シートF3を巻き出す毎に幅方向に沿うカットを施し、前記表示領域P4に対応する大きさを有する第三光学部材F13とした後、前記セパレータシートSSをキャリアとして複数の前記第三光学部材F13を搬送しつつ、前記第三光学部材F13を前記第二片面貼合パネルP12における前記液晶パネルPの第二面に貼り合わせる。   Here, the production method of the optical display device in the above embodiment is such that the liquid crystal panel P is aligned in the component width direction orthogonal to the conveyance direction of the optical display component PX with respect to the plurality of optical display components PX conveyed on the roller conveyor 5. While the strip-shaped optical member sheets F1 and F2 having a width larger than the width of the display region P4 are unwound from the raw rolls R1 and R2, the second optical member sheet F2 and the plurality of liquid crystal panels are placed on the first optical member sheet F1. The first surface of P is bonded together in order to form a second bonding sheet F22, and the facing portions of the optical member sheets F1 and F2 facing the display area P4 and the surplus portions located outside the facing portions are formed. By separating and cutting out the optical members F11 and F12 having a size corresponding to the display area P4 from the optical member sheets F1 and F2, the second bonding sheet F22.

図13は、本実施形態のフィルム貼合システム101の概略構成を示す。フィルム貼合システム101は、例えば液晶パネルや有機ELパネルといったパネル状の光学表示部品に、偏光フィルムや位相差フィルム、輝度上昇フィルムといったフィルム状の光学部材を貼合する。フィルム貼合システム101は、前記光学表示部品及び光学部材を含んだ光学部材貼合体を製造する。フィルム貼合システム101では、前記光学表示部品として液晶パネルPを用いる。フィルム貼合システム101の各部は、電子制御装置としての制御装置120(制御部)により統括制御される。   FIG. 13 shows a schematic configuration of the film bonding system 101 of the present embodiment. The film bonding system 101 bonds a film-shaped optical member such as a polarizing film, a retardation film, and a brightness enhancement film to a panel-shaped optical display component such as a liquid crystal panel or an organic EL panel.

A transport device 119 that transports the sheet SS while unwinding and feeds the third optical member F13 from the third optical member sheet F3 to the bonding position, and a third transport device 119 cuts out from the third optical member sheet F3. The pressure roller 121 is bonded to the upper surface (the display surface side of the liquid crystal panel P) of the second single-sided bonding panel P12 that the roller conveyor 105 conveys the lower surface of the optical member F13.
搬送装置119は、第一実施形態の搬送装置19と同様に、セパレータシートSSをキャリアとして複数の第三光学部材F13を連続的に搬送する。搬送装置119は、第三原反ロールR3を保持すると共にこの第三原反ロールR3から第三光学部材シート体F3Sを、第三光学部材シート体F3Sの長手方向に沿って巻き出すロール保持部119a(巻き出し部)と、第三原反ロールR3から巻き出した第三光学部材シート体F3Sを第三貼合装置118の貼合位置まで所定のシート搬送経路に沿って案内するべく第三光学部材シート体F3SのセパレータシートSS側を巻きかける単数又は複数(図では一つのみ示す)のガイドローラ119bと、シート搬送経路上の第三光学部材シート体F3SにセパレータシートSSを残したハーフカットを施す切断装置119c(カット部)と、ハーフカットを施した第三光学部材シート体F3SのセパレータシートSS側を鋭角に巻きかけてセパレータシートSSから第三光学部材F13を分離させつつ第三光学部材F13を貼合位置に供給するナイフエッジ119dと、ナイフエッジ119dを経て単独となったセパレータシートSSを巻き取るセパレータ回収部119eとを有する。   The transport device 119 continuously transports the plurality of third optical members F13 using the separator sheet SS as a carrier, similarly to the transport device 19 of the first embodiment. The transport device 119 holds the third original fabric roll R3 and rolls out the third optical member sheet F3S from the third original fabric roll R3 along the longitudinal direction of the third optical member sheet F3S. 119a (unwinding part) and the third optical member sheet F3S unwound from the third original fabric roll R3 are guided to the bonding position of the third bonding apparatus 118 along the predetermined sheet conveying path. Single or plural (only one is shown in the figure) guide rollers 119b for winding the separator sheet SS side of the optical member sheet body F3S, and a half that leaves the separator sheet SS on the third optical member sheet body F3S on the sheet conveyance path A cutting device 119c (cut portion) that performs cutting and a separator sheet SS side of the third optical member sheet F3S that has been half-cut are wound around an acute angle to set the A knife edge 119d for supplying the third optical member F13 to the bonding position while separating the third optical member F13 from the separator sheet SS, and a separator collecting unit 119e for winding up the separator sheet SS that has become independent through the knife edge 119d; Have
搬送装置119の始点に位置するロール保持部119aと搬送装置119の終点に位置するセパレータ回収部119eとは、例えば互いに同期して駆動する。これにより、ロール保持部119aが第三光学部材シート体F3Sを、第三光学部材シート体F3Sの搬送方向へ巻き出しつつ、セパレータ回収部119eがナイフエッジ119dを経て単独となったセパレータシートSSを巻き取る。   The roll holding unit 119a positioned at the start point of the transport device 119 and the separator collection unit 119e positioned at the end point of the transport device 119 are driven in synchronization with each other, for example.

Wind up.
切断装置119cは、第三光学部材シート体F3Sが所定長さ巻き出された際、第三光学部材シート体F3Sを、第三光学部材シート体F3Sの長手方向(巻き出し方向)と直交する幅方向の全幅にわたってセパレータシートSSを残して切断する(すなわち第三光学部材シートF3のみを切断する)。切断装置119cは、第三光学部材シート体F3Sの搬送中に働くテンションによってセパレータシートSSが破断しないように切断刃の進退位置を調整する。   When the third optical member sheet body F3S is unwound by a predetermined length, the cutting device 119c has a width orthogonal to the longitudinal direction (unwinding direction) of the third optical member sheet body F3S. The separator sheet SS is cut over the entire width in the direction (that is, only the third optical member sheet F3 is cut). The cutting device 119c adjusts the advancing / retreating position of the cutting blade so that the separator sheet SS is not broken by the tension acting during the conveyance of the third optical member sheet body F3S.
前記切断後の第三光学部材シート体F3Sには、第三光学部材シート体F3Sの幅方向の全幅にわたるカットラインが形成される。
ここで、ナイフエッジ119dの先端部近傍であって第三貼合装置118の貼合位置近傍のパネル搬送上流側の部位には、当該部位における第三光学部材F13の巻き出し方向下流側の切断端を検出する第一検出カメラ122が設けられる。第一検出カメラ122の検出情報は制御装置120に送られる。制御装置120は、例えば第一検出カメラ122が第三光学部材F13の下流側端を検出した時点で、搬送装置119を一旦停止させる。その後、第一検出カメラ122が第二片面貼合パネルP12の下流側端を検出した時点で、制御装置120が搬送装置119を駆動させ、第二片面貼合パネルP12と第三光学部材F13とを同期させて第三貼合装置118の貼合位置に導入可能とする。
In the third optical member sheet body F3S after the cutting, a cut line that extends over the entire width in the width direction of the third optical member sheet body F3S is formed.
Here, in the vicinity of the front end of the knife edge 119d and in the vicinity of the bonding position of the third bonding apparatus 118, the upstream side of the panel conveyance is cut downstream in the unwinding direction of the third optical member F13 at the position. A first detection camera 122 for detecting the end is provided. Detection information of the first detection camera 122 is sent to the control device 120. For example, when the first detection camera 122 detects the downstream end of the third optical member F13, the control device 120 temporarily stops the transport device 119. Then, when the 1st detection camera 122 detects the downstream end of the 2nd single-sided bonding panel P12, the control apparatus 120 drives the conveying apparatus 119, 2nd single-sided bonding panel P12, the 3rd optical member F13, Can be synchronized and introduced into the bonding position of the third bonding apparatus 118.
一方、第一検出カメラ122よりも巻き出し方向上流側であって切断装置119cよりも第三光学部材F13一つ分だけ前記巻き出し方向下流側の部位には、同じく第三光学部材F13の巻き出し方向下流側の切断端を検出する第二検出カメラ123が設けられる。第二検出カメラ123の検出情報も制御装置120に送られる。制御装置120は、例えば切断装置119cによる第三光学部材シートF3の切断後にこれを巻き出し、その切断端(第三光学部材シートF3の最上流側のカットライン)を第二検出カメラ123が検出した時点で、搬送装置119を一旦停止させる。このとき、切断装置119cによる第三光学部材シートF3のカットがなされる。すなわち、第二検出カメラ123による検出位置(第三光学部材シートF3における第二検出カメラ123の光軸延長位置に相当)と切断装置119cによるカット位置(第三光学部材シートF3における切断装置119cの切断刃進退位置に相当)との間のシート搬送経路に沿う距離が、第三光学部材F13の長さに相当する。   On the other hand, the third optical member F13 is similarly wound on the upstream side of the first detection camera 122 in the unwinding direction and downstream of the cutting device 119c by one third optical member F13. A second detection camera 123 that detects a cut end on the downstream side in the ejection direction is provided. Detection information of the second detection camera 123 is also sent to the control device 120. For example, after the third optical member sheet F3 is cut by the cutting device 119c, the control device 120 unwinds the third optical member sheet F3, and the second detection camera 123 detects the cut end (the cut line on the most upstream side of the third optical member sheet F3). At this point, the transfer device 119 is temporarily stopped. At this time, the third optical member sheet F3 is cut by the cutting device 119c. That is, the detection position by the second detection camera 123 (corresponding to the optical axis extension position of the second detection camera 123 in the third optical member sheet F3) and the cut position by the cutting device 119c (of the cutting device 119c in the third optical member sheet F3). (Corresponding to the cutting blade advance / retreat position) along the sheet conveyance path corresponds to the length of the third optical member F13.
また、切断装置119cは、第三光学部材シート体F3Sのシート搬送経路に沿って移動可能とされる。この移動により、第二検出カメラ123による検出位置と切断装置119cによるカット位置との間のシート搬送経路に沿う距離が変動する。切断装置119cの移動は制御装置120により制御され、例えば切断装置119cによる第三光学部材シートF3の切断後にこれを第三光学部材F13一つ分だけ巻き出した際、その切断端が所定位置からずれる場合には、このずれを切断装置119cの移動により補正する。   The cutting device 119c is movable along the sheet conveyance path of the third optical member sheet body F3S. By this movement, the distance along the sheet conveyance path between the detection position by the second detection camera 123 and the cutting position by the cutting device 119c varies. The movement of the cutting device 119c is controlled by the control device 120. For example, when the third optical member sheet F3 is unwound by one piece after the third optical member sheet F3 is cut by the cutting device 119c, the cut end is moved from a predetermined position. In the case of deviation, this deviation is corrected by the movement of the cutting device 119c.
なお、切断装置119cの移動により長さの異なる第三光学部材F13のカットに対応することも可能である。また、切断装置119c及び第二検出カメラ123の少なくとも一方をシート搬送方向で移動させることで、前記補正や第三光学部材F13の長さ変更を行う構成としてもよい。また、切断装置119cと第二検出カメラ123とは互いに近接するが、切断装置119cの移動等に伴う第二検出カメラ123の振動を防止するために、これらは別フレームで支持することが好ましい。   Note that it is possible to cope with the cutting of the third optical member F13 having a different length by the movement of the cutting device 119c. In addition, the correction or the length change of the third optical member F13 may be performed by moving at least one of the cutting device 119c and the second detection camera 123 in the sheet conveyance direction. Moreover, although the cutting device 119c and the second detection camera 123 are close to each other, in order to prevent vibration of the second detection camera 123 accompanying the movement of the cutting device 119c, it is preferable to support them with separate frames.
ナイフエッジ119dは、ローラコンベヤ105の上方に配置されて第三光学部材シート体F3Sの幅方向で少なくともその全幅にわたって延在する。ナイフエッジ119dは、ハーフカット後の第三光学部材シート体F3SのセパレータシートSS側に摺接するようにこれを鋭角に巻きかける。   The knife edge 119d is disposed above the roller conveyor 105 and extends at least over the entire width in the width direction of the third optical member sheet body F3S. The knife edge 119d is wound at an acute angle so as to be in sliding contact with the separator sheet SS side of the third optical member sheet body F3S after the half cut.
第三光学部材シート体F3Sは、ナイフエッジ119dで鋭角に折り返す際、セパレータシートSSから第三光学部材F13を分離させる。ナイフエッジ119dは、挟圧ロール121のパネル搬送下流側に近接して配置される。ナイフエッジ119dによりセパレータシートSSから分離した第三光学部材F13は、ローラコンベヤ105が搬送する液晶パネルPの上面に重なりつつ、挟圧ロール121の一対の貼合ローラ間に導入される。   The third optical member sheet body F3S separates the third optical member F13 from the separator sheet SS when it is folded at an acute angle by the knife edge 119d. The knife edge 119d is disposed close to the panel conveyance downstream side of the pinching roll 121. The third optical member F13 separated from the separator sheet SS by the knife edge 119d is introduced between the pair of bonding rollers of the pinching roll 121 while overlapping the upper surface of the liquid crystal panel P conveyed by the roller conveyor 105.
挟圧ロール121は、互いに軸方向を平行にして配置された一対の貼合ローラを有する。一対の貼合ローラ間には所定の間隙が形成され、この間隙内が第三貼合装置118の貼合位置となる。前記間隙内には、第二片面貼合パネルP12及び第三光学部材F13が重なり合って導入される。これら第二片面貼合パネルP12及び第三光学部材F13が、前記貼合ローラ間で挟圧されつつパネル搬送下流側に送り出される。これにより、第二片面貼合パネルP12に第三光学部材F13を貼合した両面貼合パネルP13が形成される(図7参照)。   The pinching roll 121 has a pair of laminating rollers arranged with their axial directions parallel to each other. A predetermined gap is formed between the pair of bonding rollers, and the inside of this gap is the bonding position of the third bonding device 118. In the gap, the second single-sided bonding panel P12 and the third optical member F13 are introduced overlapping each other. These 2nd single-sided bonding panels P12 and the 3rd optical member F13 are sent out to a panel conveyance downstream, being pinched between the said bonding rollers. Thereby, the double-sided bonding panel P13 which bonded the 3rd optical member F13 to the 2nd single-sided bonding panel P12 is formed (refer FIG. 7).
第一実施形態の搬送装置19と同様に、両面貼合パネルP13は、不図示の欠陥検査装置を経て欠陥(貼合不良等)の有無が検査された後、下流工程に搬送されて他の処理がなされる。   Similar to the transport device 19 of the first embodiment, the double-sided bonding panel P13 is transported to a downstream process after being inspected for defects (such as poor bonding) through a defect inspection device (not shown). Processing is done.
また、上述した第一実施形態の制御装置20と同様に、本実施形態の場合、前記検査装置で得た各光学部材シートF1,F2,F3の光学軸方向の検査データは、各光学部材シートF1,F2,F3の長手方向位置と幅方向位置とに関連付けられて制御装置120のメモリに記憶される。また、上述した第一実施形態と同様に、検査後に各光学部材シートF1,F2,F3が巻き取られて各原反ロールR1,R2,R3をそれぞれ形成する。   Similarly to the control device 20 of the first embodiment described above, in the case of this embodiment, the inspection data in the optical axis direction of each optical member sheet F1, F2, F3 obtained by the inspection device is each optical member sheet. The data are stored in the memory of the control device 120 in association with the longitudinal position and the width direction position of F1, F2, and F3. Moreover, similarly to 1st embodiment mentioned above, each optical member sheet | seat F1, F2, F3 is wound up after test | inspection, and each original fabric roll R1, R2, R3 is formed, respectively.
本実施形態では、第一実施形態の制御装置20と同様に、制御装置120に予め記憶した光学部材シートFXの各部における光学軸の面内分布の検査データに基づき、これらに貼合する光学表示部品PXのアライメントを行った上で、光学部材シートFXに光学表示部品PXを貼合している。これによって、第一実施形態と同様の効果が得られる。   In the present embodiment, similar to the control device 20 of the first embodiment, based on the inspection data of the in-plane distribution of the optical axis in each part of the optical member sheet FX stored in advance in the control device 120, the optical display to be bonded to them. After aligning the component PX, the optical display component PX is bonded to the optical member sheet FX. Thereby, the same effect as the first embodiment can be obtained.
また、図15は比較的幅の広い光学部材シートFXにその幅方向で三つの光学表示部品PXを並べて貼合する例を示すが、これに限らず、二つ以下又は四つ以上の光学表示部品PXを光学部材シートFXの幅方向で並べて貼合する構成であったり、比較的幅の狭い光学部材シートFXを幅方向に複数並べてこれらのそれぞれに光学表示部品PXを貼合する構成であってもよい。   FIG. 15 shows an example in which three optical display components PX are aligned and bonded to a relatively wide optical member sheet FX in the width direction. However, the present invention is not limited thereto, and two or less or four or more optical displays are displayed. It is a configuration in which the parts PX are arranged and bonded in the width direction of the optical member sheet FX, or a plurality of relatively narrow optical member sheets FX are arranged in the width direction and the optical display components PX are bonded to each of them. May be.
図5を参照し、第二切断装置116は、表示領域P4の外周縁をカメラ116a等の検出部で検出しつつ、表示領域P4の外周縁等に沿って第一及び第二光学部材シートF1,F2を切断する。表示領域P4の外側には、第一及び第二基板P1,P2を接合するシール剤等を配置する所定幅の額縁部Gが設けられ、この額縁部Gの幅内で第二切断装置116によるレーザーカットがなされる。
このような切断装置を用いることにより、第一実施形態と同様の効果が得られる(図9及び図10参照)。
Referring to FIG. 5, the second cutting device 116 detects the outer peripheral edge of the display area P4 with a detection unit such as a camera 116a, and the first and second optical member sheets F1 along the outer peripheral edge of the display area P4. , F2 is cut. Outside the display area P4, a frame portion G having a predetermined width for arranging a sealant or the like for bonding the first and second substrates P1 and P2 is provided. The frame is cut by the second cutting device 116 within the width of the frame portion G. Laser cut is made.
By using such a cutting device, the same effect as the first embodiment can be obtained (see FIGS. 9 and 10).
また、第三貼合装置118では、表示領域P4に対応する幅を有する帯状の第三光学部材シートF3を所定長さにカットして第三光学部材F13を形成する。第三貼合装置118は、この第三光学部材F13をセパレータシートSSと共に搬送しつつ、前記カットを行うライン内で第二片面貼合パネルP12に貼合する。このため、表示領域P4に合わせて加工した偏光板を別ラインに搬送するような場合と比べて、第三光学部材F13の寸法バラツキや貼合バラツキの影響が抑えられる。   Moreover, in the 3rd bonding apparatus 118, the strip | belt-shaped 3rd optical member sheet | seat F3 which has a width | variety corresponding to the display area P4 is cut into predetermined length, and the 3rd optical member F13 is formed. The 3rd bonding apparatus 118 is bonded to the 2nd single-sided bonding panel P12 within the line which performs the said cut, conveying this 3rd optical member F13 with separator sheet SS. For this reason, compared with the case where the polarizing plate processed according to the display area P4 is conveyed to another line, the influence of the dimensional variation of the 3rd optical member F13 and bonding variation is suppressed.
図6に示すように、光学部材シートFX(図6では第二光学部材シートF2)をレーザーカットする場合、例えば表示領域P4の一長辺の延長上にレーザーカットの始点pt1を設定し、この始点pt1からまず前記一長辺の切断を開始する。レーザーカットの終点pt2は、レーザーが表示領域P4を一周して表示領域P4の始点側の短辺の延長上に至る位置に設定する。始点pt1及び終点pt2は、光学部材シートFXの余剰部分に所定の接続代を残し、光学部材シートFXを巻き取る際の張力に耐え得るように設定される。   As shown in FIG. 6, when laser cutting the optical member sheet FX (second optical member sheet F2 in FIG. 6), for example, a laser cut start point pt1 is set on the extension of one long side of the display region P4, and this First, the cutting of the one long side is started from the starting point pt1. The end point pt2 of the laser cut is set at a position where the laser goes around the display area P4 and reaches the extension of the short side on the start point side of the display area P4. The start point pt1 and the end point pt2 are set so as to be able to withstand the tension when the optical member sheet FX is wound, leaving a predetermined connection allowance in the surplus portion of the optical member sheet FX.
以上説明したように、上記実施形態における光学表示デバイスの生産システムは、液晶パネルPに光学部材F11,F12,F13を貼合してなる光学表示デバイスの生産システムの一部をなすフィルム貼合システム101において、ローラコンベヤ105上を搬送される複数の光学表示部品PXに対し、光学表示部品PXの搬送方向と直交する部品幅方向で液晶パネルPの表示領域P4の幅よりも大きい幅を有する帯状の光学部材シートF1,F2を、原反ロールR1,R2から巻き出しつつ、第一光学部材シートF1に第二光学部材シートF2及び複数の液晶パネルPの第一面を順に貼り合わせて第二貼合シートF22とする貼合装置112,115と、前記表示領域P4に対向する前記光学部材シートF1,F2の対向部分と前記対向部分の外側に位置する余剰部分とを切り離し、前記光学部材シートF1,F2から前記表示領域P4に対応する大きさを有する光学部材F11,F12を切り出すことで、前記第二貼合シートF22から単一の前記液晶パネルP及びこれに重なる前記光学部材F11,F12を含む第二片面貼合パネルP12を切り出す第二切断装置116と、ローラコンベヤ105上を搬送される複数の前記第二片面貼合パネルP12に対し、前記部品幅方向で前記表示領域P4に対応する幅を有する帯状の第三光学部材シートF3を、第三原反ロールR3からセパレータシートSSと共に巻き出し、この第三光学部材シートF3に、前記表示領域P4に対応する長さで第三光学部材シートF3を巻き出す毎に幅方向に沿うカットを施し、前記表示領域P4に対応する大きさを有する第三光学部材F13とした後、前記セパレータシートSSをキャリアとして複数の前記第三光学部材F13を搬送しつつ、前記第三光学部材F13を前記第二片面貼合パネルP12における前記液晶パネルPの第二面に貼り合わせる第三貼合装置118とを備え、前記光学部材シートF1,F2と前記光学表示部品PXとの貼合位置で、前記光学表示部品PXに貼合わされる前記光学部材シートF1,F2の貼合面が下方を向くように、前記貼合装置112,115が前記光学部材シートF1,F2を搬送し、前記第三光学部材シートF3と前記第二片面貼合パネルP12との貼合位置で、前記第三光学部材シートF3の前記第二片面貼合パネルP12との貼合面が下方を向くように、前記第三貼合装置118が前記第三光学部材シートF3を搬送する。   As described above, the optical display device production system in the above embodiment is a film bonding system that forms a part of the optical display device production system in which the optical members F11, F12, and F13 are bonded to the liquid crystal panel P. 101, a plurality of optical display components PX conveyed on the roller conveyor 105 have a strip shape having a width larger than the width of the display area P4 of the liquid crystal panel P in the component width direction orthogonal to the conveyance direction of the optical display components PX. The optical member sheets F1 and F2 are unwound from the original rolls R1 and R2, and the second optical member sheet F2 and the first surfaces of the plurality of liquid crystal panels P are sequentially bonded to the first optical member sheet F1. The bonding devices 112 and 115 that are used as the bonding sheet F22, and the facing portions of the optical member sheets F1 and F2 that face the display area P4 and the facing surfaces. The excess part located on the outside of the minute is cut off, and the optical members F11 and F12 having a size corresponding to the display area P4 are cut out from the optical member sheets F1 and F2, so that it is simply removed from the second bonding sheet F22. A second cutting device 116 for cutting out the second single-sided bonding panel P12 including the one liquid crystal panel P and the optical members F11 and F12 overlapping therewith, and a plurality of the second single-sided bonding conveyed on the roller conveyor 105. A strip-shaped third optical member sheet F3 having a width corresponding to the display region P4 in the component width direction is unwound from the third raw roll R3 together with the separator sheet SS to the panel P12. F3 is cut along the width direction every time the third optical member sheet F3 is unwound with a length corresponding to the display area P4, and the display area P4 After making it the 3rd optical member F13 which has a corresponding magnitude | size, said 3rd optical member F13 is said 2nd single-sided bonding panel P12, conveying several said 3rd optical members F13 by using said separator sheet SS as a carrier. And a third bonding device 118 for bonding to the second surface of the liquid crystal panel P, and bonded to the optical display component PX at the bonding position of the optical member sheets F1, F2 and the optical display component PX. The bonding devices 112 and 115 convey the optical member sheets F1 and F2 so that the bonding surfaces of the optical member sheets F1 and F2 face downward, and the third optical member sheet F3 and the second single surface At the bonding position with the bonding panel P12, the third bonding device 118 is arranged so that the bonding surface with the second single-sided bonding panel P12 of the third optical member sheet F3 faces downward. The third optical member sheet F3 is conveyed.
この構成によれば、表示領域P4に対応する幅を有する帯状の第三光学部材シートF3を所定長さにカットして第三光学部材F13が形成され、この第三光学部材F13を、第三光学部材シートF3と共に巻き出したセパレータシートSSをキャリアとして搬送しつつ、前記カットを行うライン内で液晶パネルPに第三光学部材シートF3が貼合される。このため、表示領域P4に合わせて加工した偏光板を別ラインに搬送するような場合と比べて、第三光学部材F13の寸法バラツキや貼合バラツキを抑え、表示領域P4周辺の額縁部Gを縮小して表示エリアの拡大及び機器の小型化を図ることができる。
また、液晶パネルPへの貼合後の光学部材シートF1,F2のカットと、セパレータシートSSを残したハーフカット後の第三光学部材シートF3の貼合とを組み合わせることで、額縁部Gの縮小と併せてタクトタイムの短縮を図ることができる。
そして、光学部材シートFXが、光学表示部品PXとの貼合位置で粘着層側の貼合面を下方に向けるように搬送されることで、光学部材シートFXの貼合面の傷付きや異物の付着等が抑えられ、貼合不良の発生を抑制することができる。
According to this configuration, the third optical member F13 is formed by cutting the band-shaped third optical member sheet F3 having a width corresponding to the display region P4 into a predetermined length. The third optical member sheet F3 is bonded to the liquid crystal panel P in the line for performing the cutting while the separator sheet SS unwound together with the optical member sheet F3 is conveyed as a carrier. For this reason, compared with the case where the polarizing plate processed according to the display region P4 is conveyed to another line, the dimensional variation and the bonding variation of the third optical member F13 are suppressed, and the frame portion G around the display region P4 is reduced. By reducing the size, the display area can be enlarged and the device can be downsized.
Moreover, by combining the cut of the optical member sheets F1 and F2 after bonding to the liquid crystal panel P and the bonding of the third optical member sheet F3 after half-cut leaving the separator sheet SS, Along with the reduction, the tact time can be shortened.
And the optical member sheet | seat FX is conveyed so that the bonding surface by the side of the adhesion layer may face downward at the bonding position with the optical display component PX, and the bonding surface of the optical member sheet FX is damaged or foreign matter. Can be suppressed and the occurrence of poor bonding can be suppressed.
また、上記光学表示デバイスの生産システムは、ローラコンベヤ105上を搬送される前記第二片面貼合パネルP12の表面と裏面とを反転させる第三アライメント装置117を備えることで、光学表示部品PXの表面及び裏面の両方に対して光学部材シートFXを上方から容易に貼合することができる。   The optical display device production system includes the third alignment device 117 that reverses the front and back surfaces of the second single-sided bonding panel P12 conveyed on the roller conveyor 105, so that the optical display component PX The optical member sheet FX can be easily bonded to both the front surface and the back surface from above.
また、上記光学表示デバイスの生産システムは、前記第三貼合装置118が、前記第三光学部材シートF3を前記セパレータシートSSと共に巻き出すロール保持部119aと、前記第三光学部材シートF3にカットを施して前記第三光学部材F13とする切断装置119cと、前記第三光学部材シートF3にカットを施すカット位置よりも、前記第三光学部材シートF3の巻き出し方向で前記第三光学部材F13一つ分に対応する距離だけ下流側に離間した位置で、前記第三光学部材シートF3に前記カットにより形成されたカットラインを検出する第二検出カメラ123と、前記カット位置から前記下流側に前記第三光学部材F13一つ分の距離で離間した検出位置で前記カットラインを検出したときに、前記カットラインの位置に応じて前記カット位置と前記検出位置との間の距離を調整する制御装置120とを備える。   Further, in the production system for the optical display device, the third laminating apparatus 118 cuts the third optical member sheet F3 together with the separator sheet SS into the roll holding unit 119a and the third optical member sheet F3. The third optical member F13 in the unwinding direction of the third optical member sheet F3 than the cutting device 119c that performs the third optical member F13 and the cutting position for cutting the third optical member sheet F3. A second detection camera 123 for detecting a cut line formed by the cut in the third optical member sheet F3 at a position spaced downstream by a distance corresponding to one; and from the cut position to the downstream side. According to the position of the cut line when the cut line is detected at a detection position separated by a distance corresponding to one third optical member F13. And a control unit 120 for adjusting the distance between the detection position and the cutting position.
この構成によれば、第三光学部材シートF3のカット位置よりも第三光学部材F13一つ分だけ下流側に位置する第二検出カメラ123によって、前記第三光学部材F13の巻き出し方向下流側端を検出したときに、切断装置119cによって第三光学部材シートF3にカットを施すことが可能となり、規定長さの第三光学部材F13を得ることができる。また、第三光学部材シートF3の巻き出し量に誤差が生じても、第二検出カメラ123の検出情報に基づく切断装置119cの相対移動により前記誤差を補正(吸収)することが可能となる。このため、第三光学部材F13の長さの精度を確保することができ、かつ長さの異なる第三光学部材F13の切り出しにも対応することができる。   According to this configuration, the third optical member F13 is unwound in the unwinding direction of the third optical member F13 by the second detection camera 123 that is located downstream from the cutting position of the third optical member sheet F3 by one third optical member F13. When the end is detected, the third optical member sheet F3 can be cut by the cutting device 119c, and the third optical member F13 having a specified length can be obtained. Even if an error occurs in the unwinding amount of the third optical member sheet F3, the error can be corrected (absorbed) by the relative movement of the cutting device 119c based on the detection information of the second detection camera 123. For this reason, the precision of the length of the 3rd optical member F13 can be ensured, and it can respond also to cutting out of the 3rd optical member F13 from which length differs.
ここで、上記実施形態における光学表示デバイスの生産方法は、ローラコンベヤ105上を搬送される複数の光学表示部品PXに対し、光学表示部品PXの搬送方向と直交する部品幅方向で液晶パネルPの表示領域P4の幅よりも大きい幅を有する帯状の光学部材シートF1,F2を、原反ロールR1,R2から巻き出しつつ、第一光学部材シートF1に第二光学部材シートF2及び複数の液晶パネルPの第一面を順に貼り合わせて第二貼合シートF22を形成し、前記表示領域P4に対向する前記光学部材シートF1,F2の対向部分と前記対向部分の外側に位置する余剰部分とを切り離し、前記光学部材シートF1,F2から前記表示領域P4に対応する大きさを有する光学部材F11,F12を切り出すことで、前記第二貼合シートF22から単一の前記液晶パネルP及びこれに重なる前記光学部材F11,F12を含む第二片面貼合パネルP12を切り出し、ローラコンベヤ105上を搬送される複数の前記第二片面貼合パネルP12に対し、前記部品幅方向で前記表示領域P4に対応する幅を有する帯状の第三光学部材シートF3を、第三原反ロールR3からセパレータシートSSと共に巻き出し、この第三光学部材シートF3に、前記表示領域P4に対応する長さで第三光学部材シートF3を巻き出す毎に幅方向に沿うカットを施し、前記表示領域P4に対応する大きさを有する第三光学部材F13とした後、前記セパレータシートSSをキャリアとして複数の前記第三光学部材F13を搬送しつつ、前記第三光学部材F13を前記第二片面貼合パネルP12における前記液晶パネルPの第二面に貼り合わせ、前記光学部材シートF1,F2と前記光学表示部品PXとの貼合位置で、前記光学部材シートF1,F2の前記光学表示部品PXとの貼合面が下方を向くように、前記光学部材シートF1,F2を搬送し、前記第三光学部材シートF3と前記第二片面貼合パネルP12との貼合位置で、前記第三光学部材シートF3の前記第二片面貼合パネルP12との貼合面が下方を向くように、前記第三光学部材シートF3を搬送する。   Here, the production method of the optical display device in the above embodiment is such that the liquid crystal panel P is aligned in the component width direction orthogonal to the conveyance direction of the optical display component PX with respect to the plurality of optical display components PX conveyed on the roller conveyor 105. While the strip-shaped optical member sheets F1 and F2 having a width larger than the width of the display region P4 are unwound from the raw rolls R1 and R2, the second optical member sheet F2 and the plurality of liquid crystal panels are placed on the first optical member sheet F1. The first surface of P is bonded together in order to form a second bonding sheet F22, and the facing portions of the optical member sheets F1 and F2 facing the display area P4 and the surplus portions located outside the facing portions are formed. By separating and cutting out the optical members F11 and F12 having a size corresponding to the display area P4 from the optical member sheets F1 and F2, the second bonding sheet F is cut. The second single-sided bonding panel P12 including the single liquid crystal panel P and the optical members F11 and F12 overlapping therewith is cut out from 2 to a plurality of the second single-sided bonding panels P12 conveyed on the roller conveyor 105. On the other hand, a strip-shaped third optical member sheet F3 having a width corresponding to the display region P4 in the component width direction is unwound together with the separator sheet SS from the third raw roll R3, and this third optical member sheet F3 is Each time the third optical member sheet F3 is unwound with a length corresponding to the display area P4, a cut along the width direction is performed to obtain a third optical member F13 having a size corresponding to the display area P4. While transporting the plurality of third optical members F13 using the separator sheet SS as a carrier, the third optical member F13 is attached to the second single-sided bonding panel P12.
