Description

この発明は、液晶表示装置に用いられる偏光板に関し、偏光板の一方面に貼着された離型膜を、偏光板から剥離するための、偏光板の離型膜剥離装置に関する。   TECHNICAL FIELD The present invention relates to a polarizing plate used in a liquid crystal display device, and relates to a polarizing plate release film peeling apparatus for peeling a release film attached to one surface of a polarizing plate from the polarizing plate.

液晶ディスプレイにおいては、液晶、配向膜、透明電極、カラーフィルタ等を間に挟みこんだガラス基板からなる液晶セル基板と、この液晶セル基板の主表面に偏光板が貼着されている。液晶セル基板への偏光板貼付においては、偏光板の一方面に貼付けられた粘着層を露出させるために、離型膜を偏光板から引き離す必要がある。   In a liquid crystal display, a liquid crystal cell substrate composed of a glass substrate with a liquid crystal, an alignment film, a transparent electrode, a color filter and the like sandwiched therebetween, and a polarizing plate are attached to the main surface of the liquid crystal cell substrate. In attaching the polarizing plate to the liquid crystal cell substrate, it is necessary to separate the release film from the polarizing plate in order to expose the adhesive layer attached to one surface of the polarizing plate.

この離型膜を偏光板から引き離す作業工程においては、通常、偏光板吸引テーブルに偏光板を吸引固定し、離型膜に帯状の剥離テープを貼付け、この剥離テープを持ち上げることにより離型膜を偏光板から引き離している。このような装置を開示するものとして、下記特許文献１が挙げられる。   In the process of separating the release film from the polarizing plate, the polarizing plate is usually fixed by suction to the polarizing plate suction table, a strip-shaped release tape is attached to the release film, and the release film is lifted to remove the release film. It is pulled away from the polarizing plate. The following patent document 1 is mentioned as what discloses such an apparatus.

ここで、近年、液晶ディスプレイの大型化が進んでおり、従来、カラー液晶ディスプレイの大きさは、１５インチが主流であったが、今後は、３０インチ、４５インチが主流になり、その後も、液晶ディスプレイの大きさは加速度的に大型化されるものと思われる。その結果、離型膜を偏光板から確実に引き離すために用いられる剥離テープは、使い捨てられるため、その消費量も膨大となり、剥離テープに必要とされるコストも無視できなくなる。
特開２００５−１４１１３９号公報 Here, in recent years, the size of liquid crystal displays has been increasing. Conventionally, the size of color liquid crystal displays has been 15 inches, but in the future, 30 inches and 45 inches will become the mainstream. The size of the liquid crystal display is expected to increase at an accelerated rate. As a result, since the release tape used for reliably separating the release film from the polarizing plate is disposable, its consumption is enormous and the cost required for the release tape cannot be ignored.
JP 2005-141139 A

この発明が解決しようとする課題は、離型膜を偏光板から引き離すために用いられる剥離テープの消費量が膨大となり、剥離テープに必要とされるコストが上昇する点にある。したがって、この発明の目的は、離型膜を偏光板から引き離すために用いられる剥離テープを用いることなく、離型膜を偏光板から確実に引き離すことを可能とする、偏光板の離型膜剥離装置を提供することにある。   The problem to be solved by the present invention is that the consumption of the release tape used for separating the release film from the polarizing plate becomes enormous, and the cost required for the release tape increases. Accordingly, an object of the present invention is to release a release film from a polarizing plate, which can reliably separate the release film from the polarizing plate without using a release tape used for separating the release film from the polarizing plate. To provide an apparatus.

この発明に基づいた、偏光板の離型膜剥離装置においては、偏光板の一方面に貼着された離型膜を、上記偏光板から剥離するための、偏光板の離型膜剥離装置であって、上記離型膜の表面に当接し、上記離型膜の表面に接着する粘着ローラと、上記粘着ローラを保持し、上記偏光板の表面に沿って上記粘着ローラを所定方向に移動させるための駆動装置とを備えている。   In the release film peeling apparatus for polarizing plates based on this invention, the release film peeling apparatus for polarizing plates for peeling the release film attached to one surface of the polarizing plate from the polarizing plate. An adhesive roller that contacts the surface of the release film and adheres to the surface of the release film, and holds the adhesive roller, and moves the adhesive roller in a predetermined direction along the surface of the polarizing plate. And a driving device.

この発明に基づいた偏光板の離型膜剥離装置によれば、粘着ローラに偏光板の一方面に貼着された離型膜が貼着し、駆動装置を用いて粘着ローラを偏光板の表面に沿って移動することで粘着ローラが回転し、離型膜が粘着ローラの表面に巻き付きながら、偏光板の表面から剥離されることとなる。その結果、粘着ローラは、経時劣化を除き連続して用いることができるため、従来のように帯状の剥離テープを使い捨てる必要がなくなり、離型膜を偏光板から引き離すために用いられるコストを大幅に低減させることを可能とする。   According to the release film peeling device for a polarizing plate based on the present invention, the release film attached to one surface of the polarizing plate is attached to the adhesive roller, and the adhesive roller is attached to the surface of the polarizing plate using a driving device. , The adhesive roller rotates, and the release film is peeled off from the surface of the polarizing plate while being wound around the surface of the adhesive roller. As a result, the adhesive roller can be used continuously except for deterioration over time, so there is no need to dispose of a strip-shaped release tape as in the past, and the cost used to separate the release film from the polarizing plate is greatly increased. It is possible to reduce it.

以下、この発明に基づいた実施の形態における、偏光板の離型膜剥離装置について、図を参照しながら説明する。まず、図１および図２を参照して、本実施の形態における偏光板の離型膜剥離装置の原理を説明する。なお、図１および図２は、本実施の形態における偏光板の離型膜剥離装置における離型膜の剥離原理を概念的に示す第１および第２の図である。   Hereinafter, a polarizing plate release film peeling apparatus in an embodiment based on the present invention will be described with reference to the drawings. First, with reference to FIG. 1 and FIG. 2, the principle of the release film peeling apparatus for polarizing plates in the present embodiment will be described. 1 and 2 are first and second diagrams conceptually showing the release film peeling principle in the polarizing plate release film peeling apparatus in the present embodiment.

（離型膜の剥離原理）
本実施の形態における離型膜の剥離原理においては、まず、図１に示すように、偏光板１が、偏光板吸引テーブル１０に設けられた吸着パッド１１に吸引固定されている。偏光板１の偏光板吸引テーブル１０の主面には、保護膜２が設けられ、偏光板１の他方の主面には、糊層３を介在して離型膜４が貼着されている。 (Peeling principle of release film)
In the release film peeling principle in the present embodiment, first, as shown in FIG. 1, the polarizing plate 1 is sucked and fixed to a suction pad 11 provided on a polarizing plate suction table 10. A protective film 2 is provided on the main surface of the polarizing plate suction table 10 of the polarizing plate 1, and a release film 4 is attached to the other main surface of the polarizing plate 1 with an adhesive layer 3 interposed therebetween. .

まず、図１を参照して、偏光板１の端面部分に本実施の形態における粘着ローラ１００を配置させ、離型膜４の表面に粘着ローラ１００を当接させる。本実施の形態における粘着ローラ１００は、円筒形状のローラ層１０１と、このローラ層１０１の表面に設けられた粘着層１０２とを備えている。その後、図２に示すように、粘着ローラ１００を偏光板１の表面に沿って回転移動させる。これにより、粘着ローラ１００が回転し、離型膜４が粘着ローラ１００の表面に巻き付きながら、偏光板１の表面から剥離される。   First, referring to FIG. 1, the adhesive roller 100 according to the present embodiment is disposed on the end surface portion of the polarizing plate 1, and the adhesive roller 100 is brought into contact with the surface of the release film 4. The adhesive roller 100 in the present embodiment includes a cylindrical roller layer 101 and an adhesive layer 102 provided on the surface of the roller layer 101. Thereafter, as shown in FIG. 2, the adhesive roller 100 is rotationally moved along the surface of the polarizing plate 1. As a result, the adhesive roller 100 rotates and the release film 4 is peeled off from the surface of the polarizing plate 1 while being wound around the surface of the adhesive roller 100.

ここで、粘着層１０２には、比較的柔軟な材料が用いられ、偏光板１よりも軟らかい材料を用いることが好ましい。これは、粘着ローラ１００が、偏光板１に当接した際に、偏光板１の端面形状に沿って粘着層１０２が変形することにより、離型膜４の端面４ａから表面４ｂにかけて粘着ローラ１００が当接し、より確実に離型膜４を偏光板１から剥離することが可能となるからである。   Here, a relatively soft material is used for the adhesive layer 102, and a material softer than the polarizing plate 1 is preferably used. This is because when the adhesive roller 100 contacts the polarizing plate 1, the adhesive layer 102 is deformed along the shape of the end surface of the polarizing plate 1, so that the adhesive roller 100 extends from the end surface 4 a to the surface 4 b of the release film 4. This is because the release film 4 can be peeled off from the polarizing plate 1 more reliably.

（偏光板の離型膜剥離装置１０００）
次に、図３を参照して、上記離型膜の剥離原理を用いた偏光板の離型膜剥離装置１０００の構造について説明する。なお、図３は、本実施の形態における偏光板の離型膜剥離装置１０００の全体構造を示す模式図である。偏光板１を吸引固定するための偏光板吸引テーブル１０を備え、この偏光板吸引テーブル１０の表面に対してＸ方向に移動可能なベース６００が設けられている。このベース６００は、たとえば移動機構としてのプランジャ７００等により、Ｘ方向での移動を可能としている。このＸ方向は、後述の粘着ローラ１００の回転軸の軸方向（Ｙ方向）に対して直交する方向である。 (Polarizing plate release film peeling device 1000)
Next, the structure of a release film peeling apparatus 1000 for polarizing plates using the release film peeling principle will be described with reference to FIG. FIG. 3 is a schematic diagram showing the overall structure of the release film peeling apparatus 1000 for polarizing plates in the present embodiment. A polarizing plate suction table 10 for sucking and fixing the polarizing plate 1 is provided, and a base 600 that is movable in the X direction with respect to the surface of the polarizing plate suction table 10 is provided. The base 600 can be moved in the X direction by, for example, a plunger 700 as a moving mechanism. The X direction is a direction orthogonal to the axial direction (Y direction) of the rotation axis of the adhesive roller 100 described later.

ベース６００には、昇降機構としての昇降シリンダ３００を介在して、粘着ローラベース２００が固定され、この粘着ローラベース２００に粘着ローラ１００が軸周りに回動可能に取り付けられられている。昇降シリンダ３００の昇降動作（Ｚ方向への移動）に基づき、粘着ローラ１００が離型膜４の表面に当接する下降位置と、離型膜４の表面に当接しない上昇位置とが選択される。   An adhesive roller base 200 is fixed to the base 600 with an elevating cylinder 300 serving as a lifting mechanism, and the adhesive roller 100 is attached to the adhesive roller base 200 so as to be rotatable about an axis. Based on the lifting / lowering operation (movement in the Z direction) of the lifting / lowering cylinder 300, a lowered position where the adhesive roller 100 abuts on the surface of the release film 4 and an elevated position where the adhesive roller 100 does not contact the surface of the release film 4 are selected. .

昇降シリンダ３００、粘着ローラベース２００、および、粘着ローラ１００は、粘着ローラ１００の回転軸の延びる方向（Ｙ方向）に沿って、所定の間隙を隔てて３組配置されている。なお、昇降シリンダ３００、粘着ローラベース２００、および、粘着ローラ１００の組数は、偏光板１の大きさに応じて適宜選択されるものである。   The elevating cylinder 300, the adhesive roller base 200, and the adhesive roller 100 are arranged in three sets with a predetermined gap along the direction (Y direction) in which the rotation shaft of the adhesive roller 100 extends. Note that the number of sets of the lifting cylinder 300, the adhesive roller base 200, and the adhesive roller 100 is appropriately selected according to the size of the polarizing plate 1.

また、ベース６００には、隣接する粘着ローラ１００の間に、粘着ローラ１００により巻き取られた離型膜４の端部を挟み込み挟持する挟持装置が設けられている。具体的には、ベース６００にシリンダ５００が設けられ、シリンダ５００のピストンの動作に連動して、Ｘ方向に摺動する可動挟持プレート４００と、この可動挟持プレート４００とともに離型膜４を挟み込み挟持する固定挟持プレート４１０を有している。   Further, the base 600 is provided with a sandwiching device that sandwiches and sandwiches an end portion of the release film 4 wound up by the adhesive roller 100 between the adjacent adhesive rollers 100. Specifically, the cylinder 600 is provided in the base 600, and the movable clamping plate 400 that slides in the X direction in conjunction with the operation of the piston of the cylinder 500, and the release film 4 are sandwiched and clamped together with the movable clamping plate 400. A fixed clamping plate 410 is provided.

（偏光板の離型膜剥離装置１０００を用いた剥離動作）
次に、上記構成からなる偏光板の離型膜剥離装置１０００を用いた剥離動作について、図４から図７を参照して説明する。なお、図４から図７は、本実施の形態における偏光板の離型膜剥離装置１０００を用いた剥離動作を示す第１から第４の図である。 (Peeling operation using release film peeling device 1000 for polarizing plate)
Next, the peeling operation using the release film peeling apparatus 1000 for polarizing plates having the above-described configuration will be described with reference to FIGS. FIGS. 4 to 7 are first to fourth diagrams showing a peeling operation using the release film peeling apparatus 1000 for a polarizing plate in the present embodiment.

まず、図４を参照して、偏光板１の端面部分に粘着ローラ１００を配置させ、昇降シリンダ３００を下降（矢印Ａ１方向）させて、離型膜４の表面に粘着ローラ１００を当接させる。次に、図５を参照して、プランジャ７００を駆動させて、ベース６００を矢印Ａ２方向に移動させる。これにより、これにより、粘着ローラ１００が回転し、離型膜４が粘着ローラ１００の表面に巻き付きながら、偏光板１の表面から剥離される。   First, referring to FIG. 4, the adhesive roller 100 is disposed on the end surface portion of the polarizing plate 1, and the elevating cylinder 300 is lowered (in the direction of arrow A <b> 1) to bring the adhesive roller 100 into contact with the surface of the release film 4. . Next, referring to FIG. 5, plunger 700 is driven to move base 600 in the direction of arrow A2. Thereby, the adhesive roller 100 is rotated, and the release film 4 is peeled off from the surface of the polarizing plate 1 while being wound around the surface of the adhesive roller 100.

次に、図６を参照して、シリンダ５００を駆動させ、可動挟持プレート４００を矢印Ａ３方向に移動させる。これにより、隣接する粘着ローラ１００間において、偏光板１から剥離された離型膜４の端面が、可動挟持プレート４００と固定挟持プレート４１０とにより挟持される。その後、図７を参照して、プランジャ７００を駆動させて、ベース６００を矢印Ａ４方向に移動させる。これにより、これにより、可動挟持プレート４００と固定挟持プレート４１０とにより挟持された状態のまま偏光板１から離型膜４が剥離され、ベース６００を矢印Ａ４方向にさらに移動させることで、偏光板１からの離型膜４の剥離が完了する。   Next, referring to FIG. 6, the cylinder 500 is driven, and the movable clamping plate 400 is moved in the arrow A3 direction. Thereby, between the adjacent adhesive rollers 100, the end face of the release film 4 peeled from the polarizing plate 1 is sandwiched between the movable sandwiching plate 400 and the fixed sandwiching plate 410. Thereafter, referring to FIG. 7, plunger 700 is driven to move base 600 in the direction of arrow A4. Thereby, the release film 4 is peeled from the polarizing plate 1 while being held between the movable holding plate 400 and the fixed holding plate 410, and the base 600 is further moved in the direction of the arrow A4. The release of the release film 4 from 1 is completed.

（作用効果）
以上、本実施の形態に基づいた偏光板の離型膜剥離装置１０００によれば、粘着ローラ１００に偏光板１の一方面に貼着された離型膜４が貼着し、プランジャ７００を用いて粘着ローラ１００を偏光板１の表面に沿って移動することで粘着ローラ１００が回転し、離型膜４が粘着ローラ１００の表面に巻き付きながら、偏光板４の表面から剥離されることとなる。その結果、粘着ローラ１００は、経時劣化を除き連続して用いることができるため、従来のように帯状の剥離テープを使い捨てる必要がなくなり、離型膜４を偏光板１から引き離すために用いられるコストを大幅に低減させることが可能となる。 (Function and effect)
As described above, according to the release film peeling apparatus 1000 for a polarizing plate based on the present embodiment, the release film 4 attached to one surface of the polarizing plate 1 is attached to the adhesive roller 100 and the plunger 700 is used. By moving the adhesive roller 100 along the surface of the polarizing plate 1, the adhesive roller 100 rotates, and the release film 4 is peeled off from the surface of the polarizing plate 4 while being wound around the surface of the adhesive roller 100. . As a result, the adhesive roller 100 can be used continuously except for deterioration with time, so that it is not necessary to dispose a strip-like release tape as in the prior art, and is used to separate the release film 4 from the polarizing plate 1. Costs can be greatly reduced.

また、離型膜４の端面を、可動挟持プレート４００と固定挟持プレート４１０とにより挟持していることから、離型膜４を偏光板１から確実に剥がすことが可能となる。   Further, since the end face of the release film 4 is sandwiched between the movable sandwiching plate 400 and the fixed sandwiching plate 410, the release film 4 can be reliably peeled off from the polarizing plate 1.
