Description

粘着テープ貼付装置、及びそれを備えた液晶表示装置の製造装置、並びに粘着テープの貼付方法Adhesive tape affixing device, liquid crystal display manufacturing apparatus including the same, and adhesive tape affixing method
　本発明は、粘着テープ貼付装置、及びそれを備えた液晶表示装置の製造装置、並びに粘着テープの貼付方法に関するものである。 The present invention relates to an adhesive tape attaching device, an apparatus for manufacturing a liquid crystal display device including the same, and an adhesive tape attaching method.
　一般に、液晶表示パネル等の液晶モジュールには、粘着テープがその構成部品として含まれる。すなわち、斜視図である図１５に示すように、液晶表示パネル１０１は、画像が表示される表示領域１０２と、その外側周囲に形成された額縁状の非表示領域１０３とを有している。液晶表示パネル１０１の非表示領域１０３には、駆動回路であるＬＳＩ１０４が実装されている。ＬＳＩ１０４は、液晶表示パネル１０１の辺に沿って長く延びる矩形板状に形成されている。そして、非表示領域１０３には、ＬＳＩ１０４を保護するための保護テープ１０５が、当該ＬＳＩ１０４の全体を覆うように貼り付けられている。 Generally, a liquid crystal module such as a liquid crystal display panel includes an adhesive tape as a component. That is, as shown in FIG. 15 which is a perspective view, the liquid crystal display panel 101 has a display area 102 on which an image is displayed and a frame-shaped non-display area 103 formed around the outside of the display area 102. An LSI 104 that is a drive circuit is mounted on the non-display area 103 of the liquid crystal display panel 101. The LSI 104 is formed in a rectangular plate shape that extends long along the side of the liquid crystal display panel 101. A protective tape 105 for protecting the LSI 104 is affixed to the non-display area 103 so as to cover the entire LSI 104.
　また、液晶表示パネル１０１の構成部品である粘着テープには、上記保護テープ１０５以外に、光漏れを防止するための遮光テープ、外部から液晶表示パネル１０１に加わる衝撃を吸収するためのクッションテープ、及びＦＰＣ等を固定するための両面テープ等が含まれる。液晶表示パネル１０１には、通常、複数種類の粘着テープが用いられている。 In addition to the protective tape 105, the adhesive tape that is a component of the liquid crystal display panel 101 includes a light shielding tape for preventing light leakage, a cushion tape for absorbing shock applied to the liquid crystal display panel 101 from the outside, And a double-sided tape for fixing the FPC and the like. For the liquid crystal display panel 101, a plurality of types of adhesive tapes are usually used.
　上記保護テープ１０５、遮光テープ、及びクッションテープは、テープ本体の片面側に粘着剤が設けられた片面粘着構造の粘着テープである。この片面粘着構造の粘着テープについては、機械装置によって液晶表示パネル１０１へ自動的に貼り付けることが困難であるため、斜視図である図１４に示すように、ピンセット１０７によって所定の貼り付け位置に搬送した保護テープ１０５を、作業者の手１０８により押圧して液晶表示パネル１０１に貼り付けるようにしていた。 The protective tape 105, the light shielding tape, and the cushion tape are adhesive tapes having a single-sided adhesive structure in which an adhesive is provided on one side of the tape body. The adhesive tape having the single-sided adhesive structure is difficult to automatically apply to the liquid crystal display panel 101 by a mechanical device. Therefore, as shown in FIG. The transported protective tape 105 is pressed by the operator's hand 108 and attached to the liquid crystal display panel 101.
　一方、特許文献１には、粘着テープリールから引き出した片面粘着構造の粘着テープを定寸に切断して対象物に貼り付ける自動テープ貼付装置が開示されている。 On the other hand, Patent Document 1 discloses an automatic tape applicator for cutting an adhesive tape having a single-sided adhesive structure drawn from an adhesive tape reel into a predetermined size and attaching it to an object.
　側面図である図１６に示すように、従来の自動テープ貼付装置１１０は、粘着テープリール１１１と、粘着テープリール１１１から粘着テープ１１２を引き出すためのアイドルプーリ１１３と、このアイドルプーリ１１３と平行な軸心周りに回転する吸着ドラム１２０とを備えている。吸着ドラム１２０は、その軸心周りに並んで配置された複数の吸着ブロック１１４を有している。 As shown in FIG. 16, which is a side view, a conventional automatic tape sticking device 110 includes an adhesive tape reel 111, an idle pulley 113 for pulling out the adhesive tape 112 from the adhesive tape reel 111, and a parallel to the idle pulley 113. And a suction drum 120 that rotates about an axis. The suction drum 120 has a plurality of suction blocks 114 arranged side by side around its axis.
　アイドルプーリ１１３は、駆動プーリ１１６が駆動回転することにより、ベルト１１７を介して従動回転する。このことにより、粘着テープ１１２は、粘着テープリール１１１からアイドルプーリ１１３に引き出される。さらに、吸着ドラム１２０が回転することにより、アイドルプーリ１１３の粘着テープ１１２は、吸着ブロック１１４に真空吸着されて搬送される。粘着テープ１１２は、所定の切断位置においてカッター１１８により、定寸に切断されて貼付テープ片となる。貼付テープ片は、吸着ブロック１１４が吸着ドラム１２０の半径方向に移動することによって、対象物１２１の表面に押し付けられて貼り付けられることとなる。 The idle pulley 113 is driven to rotate via the belt 117 when the drive pulley 116 is driven to rotate. As a result, the adhesive tape 112 is pulled out from the adhesive tape reel 111 to the idle pulley 113. Further, when the suction drum 120 rotates, the adhesive tape 112 of the idle pulley 113 is conveyed by being vacuum-sucked to the suction block 114. The adhesive tape 112 is cut into a fixed size by a cutter 118 at a predetermined cutting position to form an adhesive tape piece. The sticking tape piece is pressed and stuck to the surface of the object 121 as the suction block 114 moves in the radial direction of the suction drum 120.

　しかし、上記特許文献１のテープ貼付装置では、粘着テープの引き出し、切断、及び貼付という一連の動作を行うことが可能であるものの、単に、吸着ブロックに吸着保持されているテープ片を貼付対象物の表面に押し付けるだけの構成であるため、その貼付対象物に貼り付けられた粘着テープに皺や気泡が生じないように、当該粘着テープを高精度に密着させて貼り付けることは、極めて困難である。 However, although the tape sticking device of Patent Document 1 can perform a series of operations such as pulling out, cutting, and sticking the adhesive tape, it simply applies the tape piece that is sucked and held by the suction block. It is extremely difficult to attach the adhesive tape with high precision so that wrinkles and bubbles do not occur on the adhesive tape applied to the object. is there.
　本発明は、斯かる点に鑑みてなされたものであり、その目的とするところは、貼付対象物に対する粘着テープの密着性を高めることにある。 The present invention has been made in view of such a point, and an object thereof is to improve the adhesiveness of the adhesive tape to the object to be pasted.
　上記の目的を達成するために、本発明に係る粘着テープ貼付装置は、一方の表面が粘着面である一方、他方の表面が非粘着面である片面粘着構造の粘着テープの供給源であるテープ供給部と、上記テープ供給部から供給された上記粘着テープの非粘着面を保持面で保持するヘッドと、上記ヘッドに保持された上記粘着テープを所定長さのテープ片に切断する切断機構とを備え、上記ヘッドに保持されている上記テープ片を貼付対象物に貼り付ける粘着テープ貼付装置を対象としている。 In order to achieve the above object, the adhesive tape applying apparatus according to the present invention is a tape that is a supply source of an adhesive tape having a single-sided adhesive structure in which one surface is an adhesive surface and the other surface is a non-adhesive surface. A supply unit, a head that holds a non-adhesive surface of the adhesive tape supplied from the tape supply unit with a holding surface, and a cutting mechanism that cuts the adhesive tape held by the head into tape pieces of a predetermined length; And an adhesive tape sticking device for sticking the tape piece held by the head to a sticking object.
　そして、上記ヘッドは、上記保持面を有する複数の分割ヘッドと、該分割ヘッドを上記貼付対象物の表面に沿って互いに接離するように駆動する駆動機構とを有し、上記複数の分割ヘッドは、該複数の分割ヘッドに保持されている上記テープ片の粘着面の一部を上記貼付対象物に接触させた状態で、互いに離隔するように上記駆動機構によって駆動されることにより、上記テープ片を上記貼付対象物に貼り付けるように構成されている。 The head includes a plurality of divided heads having the holding surface, and a drive mechanism that drives the divided heads so as to come in contact with and separate from each other along the surface of the pasting object. The tape is driven by the drive mechanism so as to be separated from each other in a state where a part of the adhesive surface of the tape piece held by the plurality of divided heads is in contact with the object to be pasted. It is comprised so that a piece may be affixed on the said sticking target object.
　また、本発明に係る液晶表示装置の製造装置は、上記粘着テープ貼付装置を備え、上記貼付対象物が液晶表示パネルであることを特徴とする。 Further, a liquid crystal display device manufacturing apparatus according to the present invention includes the above-mentioned adhesive tape sticking device, and the sticking object is a liquid crystal display panel.
　また、本発明に係る粘着テープの貼付方法は、一方の表面が粘着面である一方、他方の表面が非粘着面である片面粘着構造の粘着テープの上記非粘着面を、ヘッドの保持面に保持させる第１工程と、上記ヘッドに保持させた上記粘着テープを所定長さのテープ片に切断する第２工程と、上記ヘッドに保持されている上記テープ片を貼付対象物に貼り付ける第３工程とを有する粘着テープの貼付方法を対象としている。 In addition, the adhesive tape sticking method according to the present invention is characterized in that the non-adhesive surface of the adhesive tape having a single-sided adhesive structure in which one surface is an adhesive surface and the other surface is a non-adhesive surface is used as a holding surface of the head. A first step of holding, a second step of cutting the adhesive tape held by the head into tape pieces of a predetermined length, and a third step of sticking the tape piece held by the head to an object to be applied. The method of sticking the adhesive tape which has a process is made into object.
　そして、上記第３工程では、上記ヘッドを構成すると共に上記保持面を有する複数の分割ヘッドを、該複数の分割ヘッドに保持されている上記テープ片の粘着面の一部を上記貼付対象物に接触させた状態で、上記貼付対象物の表面に沿って互いに離隔させることにより、上記テープ片を上記貼付対象物に貼り付ける。 In the third step, the plurality of divided heads constituting the head and having the holding surface are used, and a part of the adhesive surface of the tape piece held by the plurality of divided heads is used as the pasting object. The tape piece is affixed to the pasting object by being separated from each other along the surface of the pasting object in a contact state.
　　　－作用－
　片面粘着構造の粘着テープは、次のようにして貼付対象物に貼り付けられる。 -Action-
The adhesive tape having a single-sided adhesive structure is attached to an object to be attached as follows.
　まず、粘着テープの非粘着面をヘッドの保持面に保持させる。 First, the non-adhesive surface of the adhesive tape is held on the holding surface of the head.
　ところで、両面粘着構造の両面テープの場合には、片側の剥離紙自体がテープを搬送するための手段となり得るため、比較的容易にテープを搬送することが可能である。しかし、片面粘着構造の粘着テープの場合には、粘着側と反対側に剥離紙がないため、一般に、切断されたテープ片を搬送するためには、上記特許文献１の貼付装置のように、テープ片を真空吸着手段等によって保持する必要がある。そのため、上記吸着ブロックが大掛かりとなって小型化し難く、比較的小さい対象物に粘着テープを貼り付けることが難しい。 By the way, in the case of a double-sided tape having a double-sided adhesive structure, the release paper itself on one side can be a means for transporting the tape, so that the tape can be transported relatively easily. However, in the case of an adhesive tape having a single-sided adhesive structure, since there is no release paper on the side opposite to the adhesive side, in general, in order to transport the cut tape piece, as in the pasting device of Patent Document 1, It is necessary to hold the tape piece by vacuum suction means or the like. For this reason, the suction block is large and difficult to downsize, and it is difficult to affix the adhesive tape to a relatively small object.
　これに対し、上記保持面を、粘着テープの粘着剤よりも低い粘着性を有するように構成し、当該保持面に粘着テープの非粘着面を粘着保持させることが可能である。このことにより、比較的小さい貼付対象物にも粘着テープを連続して貼り付けることが可能になる。また、保持面は、例えばスチレン系エラストマーによって容易に構成される。 On the other hand, the holding surface can be configured to have lower adhesiveness than the adhesive of the adhesive tape, and the non-adhesive surface of the adhesive tape can be adhesively held on the holding surface. This makes it possible to continuously apply the adhesive tape to a relatively small object to be applied. Further, the holding surface is easily constituted by, for example, a styrene-based elastomer.
　次に、ヘッドに保持させた粘着テープを切断機構により所定長さのテープ片に切断する。 Next, the adhesive tape held on the head is cut into tape pieces of a predetermined length by a cutting mechanism.
　次に、ヘッドを構成すると共に保持面を有する複数の分割ヘッドを、当該複数の分割ヘッドに保持されているテープ片の粘着面の一部を貼付対象物に接触させた状態で、駆動機構等によって貼付対象物の表面に沿って互いに離隔させる。そのことにより、テープ片を例えば液晶表示パネル等の貼付対象物に貼り付ける。 Next, a plurality of divided heads that constitute a head and have a holding surface, a driving mechanism or the like in a state where a part of the adhesive surface of the tape piece held by the plurality of divided heads is in contact with the object to be pasted Are separated from each other along the surface of the object to be pasted. Thus, the tape piece is attached to an object to be attached such as a liquid crystal display panel.
　このようにすれば、分割ヘッドが互いに離隔するに連れて、テープ片と貼付対象物との間の空気を外部へ押し出しながら貼付面積が増大していくため、貼付対象物に貼り付けられたテープ片に皺や気泡が生じないように、当該テープ片は高精度に密着して貼り付けられることとなる。 In this way, as the divided heads are separated from each other, the sticking area increases while pushing the air between the tape piece and the sticking object to the outside, so the tape stuck on the sticking object The tape piece is attached in close contact with high accuracy so that wrinkles and bubbles do not occur in the piece.
　本発明によれば、分割ヘッドが互いに離隔するに連れて、テープ片と貼付対象物との間の空気を外部へ押し出しながら貼付面積が増大させることができるため、貼付対象物に貼り付けられたテープ片に皺や気泡が生じないように、当該テープ片を高精度に密着させて貼り付けることができる。 According to the present invention, as the divided heads are separated from each other, the affixing area can be increased while pushing the air between the tape piece and the affixing object to the outside. The tape piece can be attached with high precision so that no wrinkles or bubbles are generated on the tape piece.

　本実施形態１の粘着テープ貼付装置１は、図１に示すように、粘着テープとしての保護テープ１０をテープ片１１に切断して、貼付対象物としての液晶表示パネル２０に貼り付けるように構成されている。また、本実施形態１における液晶表示装置の製造装置５は、上記粘着テープ貼付装置１を備え、液晶表示パネル２０に保護テープ１０等の粘着テープを貼り付けて、液晶表示装置を製造するように構成されている。 As shown in FIG. 1, the adhesive tape sticking apparatus 1 of this Embodiment 1 is comprised so that the protective tape 10 as an adhesive tape may be cut | disconnected to the tape piece 11, and it affixes on the liquid crystal display panel 20 as a sticking target object. Has been. Moreover, the manufacturing apparatus 5 of the liquid crystal display device according to the first embodiment includes the above-described adhesive tape attaching device 1 and attaches an adhesive tape such as a protective tape 10 to the liquid crystal display panel 20 to manufacture the liquid crystal display device. It is configured.
　ここで、保護テープ１０は、図１１に拡大して示すように、樹脂からなるテープ本体１２と、その一方の表面に設けられた粘着剤１３とにより構成されている。そのことにより、保護テープ１０は、一方の表面が粘着面１４である一方、他方の表面が非粘着面１５である片面粘着構造を有している。尚、テープ本体１２は複数層からなる積層体としてもよい。 Here, as shown in FIG. 11 in an enlarged manner, the protective tape 10 is composed of a tape main body 12 made of resin and an adhesive 13 provided on one surface thereof. Accordingly, the protective tape 10 has a single-sided adhesive structure in which one surface is an adhesive surface 14 and the other surface is a non-adhesive surface 15. The tape body 12 may be a laminated body composed of a plurality of layers.
　粘着テープ貼付装置１は、図１に示すように、液晶表示パネル２０が載置されるステージ２１と、ステージ２１上で昇降可能に設けられたユニット本体２２と、ユニット本体２２にそれぞれ回転可能に支持されたテープリール２３及び回転ドラム２４とを備えている。 As shown in FIG. 1, the adhesive tape attaching device 1 includes a stage 21 on which the liquid crystal display panel 20 is placed, a unit main body 22 that can be moved up and down on the stage 21, and a unit main body 22 that is rotatable. A supported tape reel 23 and a rotating drum 24 are provided.
　テープリール２３は、粘着テープの供給源としてのテープ供給部であって、長尺の保護テープ１０が巻き付けられている。回転ドラム２４は、テープリール２３とステージ２１との間に配置されている。テープリール２３及び回転ドラム２４の回転軸心は、互いに平行であり、かつ、ステージ２１表面に対しても平行になっている。 The tape reel 23 is a tape supply unit as a supply source of the adhesive tape, and the long protective tape 10 is wound around the tape reel 23. The rotary drum 24 is disposed between the tape reel 23 and the stage 21. The rotation axes of the tape reel 23 and the rotary drum 24 are parallel to each other and are also parallel to the surface of the stage 21.
　回転ドラム２４は円板状に形成されている。回転ドラム２４の回転軸２７は、ユニット本体２２に設けられたブラケット２８に支持されている。この回転ドラム２４には、保護テープ１０の非粘着面１５を保持面３１で保持する複数のヘッド３０が、当該回転ドラム２４の回転軸心周りに所定の間隔で配置されている。本実施形態１では、例えば４つのヘッド３０が等間隔で配置されている。 The rotating drum 24 is formed in a disk shape. A rotary shaft 27 of the rotary drum 24 is supported by a bracket 28 provided on the unit main body 22. In the rotating drum 24, a plurality of heads 30 that hold the non-adhesive surface 15 of the protective tape 10 with the holding surface 31 are arranged around the rotation axis of the rotating drum 24 at a predetermined interval. In the first embodiment, for example, four heads 30 are arranged at equal intervals.
　また、ユニット本体２２には、回転ドラム２４の回転軸心とそれぞれ平行な回転軸心を有するガイドローラ２５及び押し付けローラ２６が設けられている。ガイドローラ２５は、テープリール２３から引き出された保護テープ１０の非粘着面１５が巻き掛けられて、当該保護テープ１０を適切な方向に搬送するようになっている。 The unit main body 22 is provided with a guide roller 25 and a pressing roller 26 each having a rotation axis parallel to the rotation axis of the rotary drum 24. The guide roller 25 is configured so that the non-adhesive surface 15 of the protective tape 10 drawn out from the tape reel 23 is wound around and the protective tape 10 is conveyed in an appropriate direction.
　一方、押し付けローラ２６は、例えば非粘着性のフッ素樹脂によって構成され、ガイドローラ２５側から供給される保護テープ１０の非粘着面１５をヘッド３０側へ押圧して、当該保護テープ１０をヘッド３０の保持面３１に保持させるようになっている。 On the other hand, the pressing roller 26 is made of, for example, non-adhesive fluororesin, and presses the non-adhesive surface 15 of the protective tape 10 supplied from the guide roller 25 side toward the head 30, so that the protective tape 10 is pressed against the head 30. It is made to hold on the holding surface 31.
　ここで、本実施形態１におけるヘッド３０の保持面３１は、保護テープ１０の粘着剤１３よりも低い粘着性を有し、保護テープ１０（テープ片１１）を粘着保持するように構成されている。例えば、保持面３１は、スチレン系エラストマーによって構成されている。 Here, the holding surface 31 of the head 30 in the first embodiment has a lower adhesiveness than the adhesive 13 of the protective tape 10 and is configured to hold the protective tape 10 (tape piece 11) in an adhesive manner. . For example, the holding surface 31 is made of a styrene elastomer.
　さらに、粘着テープ貼付装置１は、ヘッド３０に保持された保護テープ１０を所定長さのテープ片１１に切断する切断機構２９を備えている。切断機構２９は、カッター刃からなり、図示省略の駆動機構により水平移動するように駆動されて、保護テープ１０に対して進退するように構成されている。 Furthermore, the adhesive tape applying apparatus 1 includes a cutting mechanism 29 that cuts the protective tape 10 held by the head 30 into tape pieces 11 having a predetermined length. The cutting mechanism 29 is composed of a cutter blade, and is configured to move forward and backward with respect to the protective tape 10 by being driven to move horizontally by a drive mechanism (not shown).
　一方、液晶表示パネル２０は、図１に示すように、画像が表示される表示領域４２と、その外側周囲に形成された額縁状の非表示領域４３とを有している。液晶表示パネル２０の非表示領域４３には、駆動回路であるＬＳＩ４４が実装されている。ＬＳＩ４４は、液晶表示パネル２０の辺に沿って長く延びる矩形板状に形成されている。このＬＳＩ４４は、非表示領域４３に貼り付けられたテープ片１１により覆われて保護されることとなる。 On the other hand, as shown in FIG. 1, the liquid crystal display panel 20 has a display area 42 on which an image is displayed and a frame-like non-display area 43 formed around the outside thereof. An LSI 44 that is a drive circuit is mounted in the non-display area 43 of the liquid crystal display panel 20. The LSI 44 is formed in a rectangular plate shape that extends long along the side of the liquid crystal display panel 20. The LSI 44 is covered and protected by the tape piece 11 attached to the non-display area 43.
　次に、ヘッド３０の構成について詳述する。 Next, the configuration of the head 30 will be described in detail.
　上記ヘッド３０は、上記保持面３１を有する複数の分割ヘッド３３と、この分割ヘッド３３を互いに接離するように駆動する駆動機構３４とを有している。 The head 30 includes a plurality of divided heads 33 having the holding surface 31 and a drive mechanism 34 that drives the divided heads 33 to come in contact with and away from each other.
　ヘッド３０は、例えば２つの分割ヘッド３３を有し、各分割ヘッド３３は、テープ片１１を液晶表示パネル２０に貼り付ける際に、この液晶表示パネル２０の表面と平行となるように対向する対向面３３ａと、対向面３３ａに連続して形成され、回転ドラム２４の外周に沿うように傾斜する傾斜面３３ｂとを有している。各分割ヘッド３３の対向面３３ａは、当該分割ヘッド３３が互いに接触した状態で、同一の平面を構成するようになっている。 The head 30 includes, for example, two divided heads 33, and each divided head 33 is opposed to be parallel to the surface of the liquid crystal display panel 20 when the tape piece 11 is attached to the liquid crystal display panel 20. It has a surface 33 a and an inclined surface 33 b that is formed continuously with the facing surface 33 a and is inclined along the outer periphery of the rotating drum 24. The facing surfaces 33a of the divided heads 33 constitute the same plane with the divided heads 33 in contact with each other.
　駆動機構３４は、ブラケット２８に設けられたレバー３６を回動させることによりロッド３７を進退させるシリンダ部３８を有している。ロッド３７の先端は、取付部３９を介して分割ヘッド３３に取付固定されている。そうして、駆動機構３４は、ヘッド３０の上記対向面３３ａが液晶表示パネル２０に対向した状態で、シリンダ部３８により各ロッド３７をそれぞれ同期して進退させることによって、分割ヘッド３３を液晶表示パネル２０の表面に沿って互いに接近又は離隔させるようになっている。 The drive mechanism 34 has a cylinder portion 38 that moves the rod 37 forward and backward by rotating a lever 36 provided on the bracket 28. The tip of the rod 37 is fixedly attached to the split head 33 via an attachment portion 39. Then, the drive mechanism 34 moves the rods 37 in synchronization with each other by the cylinder portion 38 in a state where the facing surface 33a of the head 30 faces the liquid crystal display panel 20, thereby causing the divided head 33 to display the liquid crystal display. Along the surface of the panel 20, they are made to approach or separate from each other.
　こうして、複数の分割ヘッド３３は、この分割ヘッド３３に保持されているテープ片１１の粘着面１４の一部を上記対向面３３ａにより液晶表示パネル２０に接触させた状態で、互いに離隔するように駆動機構３４によって駆動される。そのことにより、テープ片１１を液晶表示パネル２０に貼り付ける。 Thus, the plurality of divided heads 33 are separated from each other with a part of the adhesive surface 14 of the tape piece 11 held by the divided head 33 being in contact with the liquid crystal display panel 20 by the facing surface 33a. It is driven by the drive mechanism 34. As a result, the tape piece 11 is attached to the liquid crystal display panel 20.
　ここで、液晶表示パネル２０の表面には、その非表示領域４３に実装されたＬＳＩ４４によって段差部４４が形成されている。一方、ヘッド３０の保持面３１は、分割ヘッド３３の移動方向に延びると共に段差部４４に係合する段差表面を有している。すなわち、ヘッド３０（分割ヘッド３３）の保持面３１には、段差表面を構成する凹溝５０が分割ヘッド３３の移動方向に延びるように形成されている。 Here, a stepped portion 44 is formed on the surface of the liquid crystal display panel 20 by the LSI 44 mounted in the non-display area 43. On the other hand, the holding surface 31 of the head 30 has a step surface that extends in the moving direction of the divided head 33 and engages the step portion 44. That is, the concave surface 50 that forms the step surface is formed on the holding surface 31 of the head 30 (the divided head 33) so as to extend in the moving direction of the divided head 33.
　この凹溝５０の溝幅は、ＬＳＩ４４の幅よりも僅かに広くなっている。そのことにより、図９及び図１０に示すように、凹溝５０の内壁面によってテープ片１１をＬＳＩ４４の上面及び側面に押し付けて密着させるようになっている。 The groove width of the concave groove 50 is slightly wider than the width of the LSI 44. As a result, as shown in FIGS. 9 and 10, the tape piece 11 is pressed and brought into close contact with the upper surface and the side surface of the LSI 44 by the inner wall surface of the groove 50.
　　－粘着テープの貼付方法－
　次に、粘着テープの貼付方法について説明する。 -Adhesive tape application method-
Next, a method for applying the adhesive tape will be described.
　本実施形態１では、上記粘着テープ貼付装置１によって、ＬＳＩ４４を保護するための保護テープ１０（テープ片１１）を液晶表示パネル２０に貼り付けて液晶表示装置を製造する。 In the first embodiment, a protective tape 10 (tape piece 11) for protecting the LSI 44 is attached to the liquid crystal display panel 20 by the adhesive tape applying device 1 to manufacture a liquid crystal display device.
　まず、ユニット本体２２を上方に退避させた状態で、ステージ２１に液晶表示パネル２０を載置する。また、第１工程として、保護テープ１０の非粘着面１５をヘッド３０の保持面３１に保持させる。 First, the liquid crystal display panel 20 is placed on the stage 21 with the unit main body 22 retracted upward. Further, as the first step, the non-adhesive surface 15 of the protective tape 10 is held on the holding surface 31 of the head 30.
　すなわち、回転ドラム２４を図１において反時計回りに回転させることにより、テープリール２３から保護テープ１０を引き出す。保護テープ１０は、ガイドローラ２５を介してヘッド３０側に供給される。ヘッド３０に供給された保護テープ１０は、押し付けローラ２６によって、ヘッド３０の保持面３１に押し付けられる。 That is, the protective tape 10 is pulled out from the tape reel 23 by rotating the rotating drum 24 counterclockwise in FIG. The protective tape 10 is supplied to the head 30 side via the guide roller 25. The protective tape 10 supplied to the head 30 is pressed against the holding surface 31 of the head 30 by the pressing roller 26.
　このとき、押し付けローラ２６が非粘着性のフッ素樹脂によって構成される一方、ヘッド３０の保持面３１が粘着性を有するスチレン系エラストマーによって構成されているため、容易且つ確実に、保護テープ１０の非粘着面１５が上記保持面３１に粘着保持されることとなる。 At this time, the pressing roller 26 is made of a non-adhesive fluororesin, while the holding surface 31 of the head 30 is made of an adhesive styrene-based elastomer. The adhesive surface 15 is adhesively held on the holding surface 31.
　続いて、第２工程として、ヘッド３０に保持させた保護テープ１０を所定長さのテープ片１１に切断する。すなわち、押し付けローラ２６によって保護テープ１０を保持したヘッド３０を、さらに反時計回りに所定長さだけ回動したところで、切断機構２９であるカッター刃を駆動して上記保護テープ１０を切断する。このとき、保護テープ１０の非粘着面１５は、ヘッド３０における対向面３３ａ及び傾斜面３３ｂによって支持されている。 Subsequently, as a second step, the protective tape 10 held by the head 30 is cut into tape pieces 11 having a predetermined length. That is, when the head 30 holding the protective tape 10 by the pressing roller 26 is further rotated by a predetermined length counterclockwise, the cutter blade as the cutting mechanism 29 is driven to cut the protective tape 10. At this time, the non-adhesive surface 15 of the protective tape 10 is supported by the facing surface 33 a and the inclined surface 33 b of the head 30.
　そうして、ＬＳＩ４４を十分に覆うことができる長さのテープ片１１が形成される。尚、この保護テープ１０の切断は、隣り合うヘッド３０同士の隙間において行う。 Thus, the tape piece 11 having a length that can sufficiently cover the LSI 44 is formed. The protective tape 10 is cut in the gap between the adjacent heads 30.
　続いて、第３工程として、ヘッド３０に保持されているテープ片１１を液晶表示パネル２０に貼り付ける。すなわち、ヘッド３０の対向面３３ａが液晶表示パネル２０の非表示領域４３に対向した状態で、ユニット本体２２を下降させることにより、ヘッド３０に保持されているテープ片１１を上記ＬＳＩ４４及びその周囲の液晶表示パネル２０表面に押し付ける。 Subsequently, as a third step, the tape piece 11 held by the head 30 is attached to the liquid crystal display panel 20. That is, by lowering the unit main body 22 with the facing surface 33a of the head 30 facing the non-display area 43 of the liquid crystal display panel 20, the tape piece 11 held by the head 30 is moved to the LSI 44 and its surroundings. Press against the surface of the liquid crystal display panel 20.
　このことにより、テープ片１１の粘着面１４の一部が、ヘッド３０の対向面３３ａによってＬＳＩ４４の中央領域及びその周囲の液晶表示パネル２０表面に接触して貼り付けられる。続いて、この一部貼り付け状態で、分割ヘッド３３を液晶表示パネル２０の表面に沿って互いに離間させることにより、テープ片１１を液晶表示パネル２０の表面に貼り付ける。 Thereby, a part of the adhesive surface 14 of the tape piece 11 is attached to the central region of the LSI 44 and the surface of the liquid crystal display panel 20 around the LSI 44 by the facing surface 33a of the head 30. Subsequently, the tape pieces 11 are attached to the surface of the liquid crystal display panel 20 by separating the divided heads 33 from each other along the surface of the liquid crystal display panel 20 in the partially attached state.
　すなわち、図２～図７に示すように、レバー３６を回動させることにより駆動機構３４の各シリンダ部３８を作動させて、一対のロッド３７を伸張させる。そのことにより、１つのヘッド３０を構成している２つの分割ヘッド３３を、液晶表示パネル２０の表面に沿って互いに離隔するようにスライド移動させる。このとき、各分割ヘッド３３の対向面３３ａは、液晶表示パネル２０の表面に平行な状態を維持している。こうして、各分割ヘッド３３の対向面３３ａは、テープ片１１をその中央領域から左右両側へ徐々に押し付けていく。 That is, as shown in FIGS. 2 to 7, by rotating the lever 36, the cylinder portions 38 of the drive mechanism 34 are operated to extend the pair of rods 37. As a result, the two divided heads 33 constituting one head 30 are slid along the surface of the liquid crystal display panel 20 so as to be separated from each other. At this time, the facing surface 33 a of each divided head 33 maintains a state parallel to the surface of the liquid crystal display panel 20. Thus, the facing surface 33a of each divided head 33 gradually presses the tape piece 11 from its central region to both the left and right sides.
　さらに、ヘッド３０及び分割ヘッド３３には、分割ヘッド３３の移動方向に延びる凹溝５０が形成されているため、テープ片１１は、分割ヘッド３３の移動に伴って、凹溝５０の内壁面によりＬＳＩ４４の上面及び側面に押し付けられて密着する。 Further, since the concave groove 50 extending in the moving direction of the divided head 33 is formed in the head 30 and the divided head 33, the tape piece 11 is moved by the inner wall surface of the concave groove 50 as the divided head 33 moves. The LSI 44 is pressed against and closely contacts the upper surface and side surfaces of the LSI 44.
　以上の工程により、テープ片１１がＬＳＩ４４を覆うように液晶表示パネル２０に貼り付けられる。そして、回転ドラム２４を回転させると共にレバー３６を回動操作することにより、上記各工程が順次繰り返され、複数の液晶表示パネル２０にテープ片１１がそれぞれ貼り付けられる。 Through the above steps, the tape piece 11 is attached to the liquid crystal display panel 20 so as to cover the LSI 44. Then, by rotating the rotating drum 24 and rotating the lever 36, the above steps are sequentially repeated, and the tape pieces 11 are attached to the plurality of liquid crystal display panels 20, respectively.
　　－実施形態１の効果－
　ここで、上述の片面粘着構造の粘着テープとは異なり、両面粘着構造の両面テープを対象物に貼り付ける場合には、当該テープの片側に設けられた剥離紙がテープを搬送するための手段となり得るため、比較的容易にテープを搬送することが可能である。しかし、本実施形態１のように、片面粘着構造の粘着テープ（保護テープ１０）の場合には、粘着面１４と反対側に剥離紙がないため、一般に、切断されたテープ片１１を搬送するためには、テープ片１１を真空吸着手段等によって保持する必要がある。そのため、真空吸着手段が大掛かりとなって小型化し難く、比較的小さい対象物（例えば携帯電話機を構成する液晶表示パネル等）に粘着テープ（保護テープ１０）を高精度に貼り付けることは難しい。 -Effect of Embodiment 1-
Here, unlike the above-mentioned single-sided adhesive structure adhesive tape, when a double-sided adhesive structure double-sided tape is applied to an object, the release paper provided on one side of the tape serves as a means for transporting the tape. Therefore, it is possible to convey the tape relatively easily. However, in the case of an adhesive tape having a single-sided adhesive structure (protective tape 10) as in Embodiment 1, there is no release paper on the side opposite to the adhesive surface 14, and thus the cut tape piece 11 is generally conveyed. For this purpose, the tape piece 11 needs to be held by a vacuum suction means or the like. Therefore, it is difficult to reduce the size because the vacuum suction means is large, and it is difficult to attach the adhesive tape (protective tape 10) to a relatively small object (for example, a liquid crystal display panel constituting a mobile phone) with high accuracy.
　これに対し、本実施形態１では、ヘッド３０の保持面３１を、保護テープ１０の粘着剤１３よりも低い粘着性を有するように構成したので、当該保持面３１に保護テープ１０の非粘着面１５を粘着保持させることができる。このことにより、上記液晶表示パネル２０及び他の比較的小さい貼付対象物に対して、保護テープ１０を容易に連続して貼り付けることが可能になる。また、保持面３１は、スチレン系エラストマーによって好適に構成できる。 On the other hand, in the first embodiment, since the holding surface 31 of the head 30 is configured to have lower adhesiveness than the adhesive 13 of the protective tape 10, the non-adhesive surface of the protective tape 10 is formed on the holding surface 31. 15 can be adhered and held. Accordingly, the protective tape 10 can be easily and continuously attached to the liquid crystal display panel 20 and other relatively small objects to be attached. Moreover, the holding surface 31 can be suitably comprised with a styrene-type elastomer.
　ここで、図１２及び図１３は比較例を示している。図１２は、参考例における液晶表示パネルに貼り付けられた保護テープを示す平面図である。図１３は、図１２におけるXIII－XIII線断面図である。 Here, FIG. 12 and FIG. 13 show comparative examples. FIG. 12 is a plan view showing the protective tape attached to the liquid crystal display panel in the reference example. 13 is a cross-sectional view taken along line XIII-XIII in FIG.
　比較例では、ＬＳＩ２４４が実装された液晶表示パネル２２０の表面に、テープ片２１１が上方から（図１２で紙面手前側から）一度に貼り付けられている。この比較例では、テープ片２１１と液晶表示パネル２２０との間に空気が抜けきれずに気泡２０２として残ってしまっている。また、ＬＳＩ２４４の側面に隙間２０３が生じると共に、皺２０１が生じている。このように、テープ片２１１を上方から一度に貼り付けると、テープ片２１１の密着性は低下し易い。 In the comparative example, the tape piece 211 is attached to the surface of the liquid crystal display panel 220 on which the LSI 244 is mounted from the upper side (from the front side in FIG. 12) at a time. In this comparative example, air cannot be completely removed between the tape piece 211 and the liquid crystal display panel 220 and remains as the bubbles 202. Further, a gap 203 is formed on the side surface of the LSI 244 and a ridge 201 is generated. Thus, if the tape piece 211 is affixed at once from the top, the adhesiveness of the tape piece 211 tends to be lowered.
　これに対し、本実施形態１では、複数の分割ヘッド３３によってヘッド３０を構成し、互いに結合している分割ヘッド３３の対向面３３ａによって、テープ片１１の一部である中央領域を液晶表示パネル２０に貼り付けた状態で、当該分割ヘッド３３を液晶表示パネル２０の表面に沿って互いに離隔させるようにしたので、各分割ヘッド３３が離隔するに連れて、テープ片１１と液晶表示パネル２０との間の空気を外部へ押し出しながら貼付面積が増大していくため、図９及び図１０に示すように、液晶表示パネル２０に貼り付けられたテープ片１１に皺や気泡が生じないように、当該テープ片１１を飛躍的に高精度に密着して貼り付けることができる。 On the other hand, in the first embodiment, the head 30 is constituted by a plurality of divided heads 33, and the central region which is a part of the tape piece 11 is defined by the liquid crystal display panel by the opposing surface 33a of the divided heads 33 coupled to each other. 20, the divided heads 33 are separated from each other along the surface of the liquid crystal display panel 20, so that the tape pieces 11 and the liquid crystal display panel 20 are separated from each other as the divided heads 33 are separated from each other. As shown in FIG. 9 and FIG. 10, as shown in FIG. 9 and FIG. 10, so as not to cause wrinkles and bubbles in the tape piece 11 attached to the liquid crystal display panel 20. The tape piece 11 can be stuck and pasted with great precision.
　さらに、液晶表示パネル２０の表面がＬＳＩ４４によって段差状に形成されていても、ヘッド３０の保持面３１に、分割ヘッド３３の移動方向に延びると共に段差部４４に係合する段差表面（凹溝５０）を形成するようにしたので、分割ヘッド３３が互いに離隔する際に、液晶表示パネル２０におけるＬＳＩ４４の段差形状に合わせて、テープ片１１を上記凹溝５０の内壁面によりＬＳＩ４４の上面及び側面に押し付けて高精度に密着させることができる。 Further, even if the surface of the liquid crystal display panel 20 is formed in a stepped shape by the LSI 44, a stepped surface (concave groove 50) that extends in the moving direction of the divided head 33 and engages the stepped portion 44 on the holding surface 31 of the head 30. When the divided heads 33 are separated from each other, the tape piece 11 is placed on the upper surface and side surfaces of the LSI 44 by the inner wall surface of the concave groove 50 in accordance with the step shape of the LSI 44 in the liquid crystal display panel 20. It can be pressed and brought into close contact with high accuracy.
