- the suction device 30 does not move during laser cutting, and the distance d is smaller than when the suction device 30 moves during laser cutting, which contributes to downsizing of the suction device 30.
- a support air channel 41 is formed in the lower wall 34 of the dust collection box 31.
- the flow path 41 feeds support air introduced from an introduction port 42 opened to the lower end portion of the rear wall 39 to the outlet port 43 opened to the lower surface of the extension portion 35.
- a thin guide plate 44 is fixed to the lower surface of the front portion of the lower wall 34, and a blowing nozzle 51 that opens in front of the lower wall 34 is formed between the guide plate 44 and the lower wall 34.
- the blowout nozzle 51 forms a blowout port 52 extending over the entire width of the dust collection box 31 just like the suction port 37 just below the suction port 37 of the dust collection box 31.
- the suction device 30 raises the dust collection box 31 to retract from the cutting position, and when performing the suction operation at the cutting position, the dust collection box 31 is lowered.
- the dust collection box 31 is brought into contact with the uppermost surface of the optical member sheet FX that cuts the lower surface of the guide plate 44, and the suction port 37 and the blowout port 52 are disposed on the downstream side and in the vicinity of the cutting line SX. .
- the optical member sheet FX is laser-cut, dust-like decomposition products (fumes) generated by melting and decomposition reactions thereof can be collected by the dust collection box 31.
- the wind pressure at the tip of the suction nozzle 36 is set to 0.1 kPa or more at static pressure, and the wind speed is set to 7 m / s or more.
- the wind pressure and wind speed at the tip of the blowing nozzle 51 are set to be smaller than that of the suction nozzle 36. Therefore, the support air blown out by the blow-out nozzle 51 flows shortly to the suction port 37 side immediately above the blow-out port 52 and is sucked by the suction nozzle 36. By this air flow, fume attachment to the upper surface of the optical member sheet FX is effectively suppressed in the range of the distance d between the suction port 37 and the cutting line SX.
- the support air blown out by the blowout nozzle 51 is warm air, and by giving thermal energy to the fumes that are sublimated, the attachment of fumes to the optical member sheet FX is further suppressed.
- the sheet piece F1X and the optical display component P can be bonded to each other in the head unit 150. Bonding can be performed in a state where generation of bubbles and air bubbles is eliminated. Therefore, product quality can be improved. Moreover, according to this modification, the fume produced by laser processing in the dust collector 20 can be sucked without leakage over the entire length of the cutting line SX. As a result, it is possible to prevent fume from adhering to the product surface and to prevent line contamination due to fume adhering to the product.
- FIG. 11 is a diagram illustrating a cutting process of the sheet piece FXm in the production system of the present embodiment.
- the difference from the first embodiment is that the sheet piece FXm bonded to the optical display component P by the bonding head is a slightly larger sheet piece than the optical member FO of the target size. And after the sheet piece FXm is bonded to the optical display component P, the excess portion of the sheet piece FXm is cut by the cutting device 184. Therefore, in the following description, it demonstrates centering around the cutting process of the sheet piece FXm.
- the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
- the cross-sectional structure of the sheet piece FXm is the same as that of the sheet piece F1X shown in FIG.
- the sheet piece FXm is obtained by cutting the long optical member sheet FX shown in FIG. 1 into a predetermined size.
- the sheet piece FXm is slightly larger than the size corresponding to the outer dimension of the optical display component P (the size of the first region FB).
- size corresponding to the external dimension of the optical display component P means a size that does not cause a surplus part that causes a problem in actual use when bonded to the optical display component P. Since the sheet piece FXm is larger than the size corresponding to the external dimension of the optical display component P, the surplus portion (second region FS) that causes a problem in actual use is cut by the cutting device 184.
- the laminating apparatus for laminating the sheet piece FXm to the optical display component P is the same as the laminating apparatus 100 described in the first embodiment.
- the detection apparatus 189 and the cutting device 184 are provided on the conveyance line on the downstream side of the bonding apparatus.
- the detection device 189 includes an imaging device 183 that images the optical display component P on which the sheet piece FXm is bonded.
- the detection device 189 detects the cut line WCL of the sheet piece FXm (position where the sheet piece FXm should be cut) based on the imaging data of the imaging device 183.
- the imaging device 183 images the optical display component P from above the optical display component P placed on the cutting stage 185 through the sheet piece FXm.
- the imaging device 183 captures images of four corners of a substrate (for example, a color filter substrate) of the optical display component P to which the sheet piece FXm is bonded.
- the detection device 189 performs image processing on the imaging data to detect the position of the outer peripheral edge of the substrate, and detects the position of the outer peripheral edge as the cut line WCL of the sheet piece FXm.
- the control device 190 controls the cutting device 189 based on the information on the cut line WCL sent from the detection device 189, and cuts the sheet piece FXm along the cut line WCL. Thereby, the first area FB facing the display area of the sheet piece FXm and the second area FS outside the first area FB are separated, and the optical member FO having a target size is cut out from the sheet piece FXm.
- the cut line WCL of the sheet piece FXm is detected for each optical display component P conveyed on the conveyance line. Therefore, even if there is a size variation for each optical display component P, the optical member FO having a size corresponding to the outer dimension of the optical display component P can be reliably cut out from the sheet piece FXm.
- the optical member FO having a desired size is bonded to a desired position of the optical display component P by adopting a window cut method.
- the direction of the optical axis of the sheet piece FXm may deviate from the originally designed direction due to manufacturing errors.
- the direction of the optical axis of the sheet piece FXm (optical member sheet FX) is measured in advance, and the relative bonding position between the sheet piece FXm and the optical display component P can be adjusted based on the measurement result.
- the size of the sheet piece FXm matches the size of the target optical member FO, such adjustment cannot be performed.
- the window cut method the sheet piece FXm larger than the optical member FO is bonded to the optical display component P, and then the excess portion of the sheet piece FXm is cut, and thus such adjustment is possible.
- the bonding position (relative bonding position) of the sheet piece FXm with respect to the optical display component P can be determined as follows.
- a plurality of inspection points CP are set in the width direction of the optical member sheet FX, and the direction of the optical axis of the optical member sheet FX is detected at each inspection point CP.
- the timing for detecting the optical axis may be at the time of manufacturing the original fabric roll RX (see FIG. 1), or may be until the optical member sheet FX is unwound from the original fabric roll RX and half-cut.
- Data in the optical axis direction of the optical member sheet FX is stored in a storage device (not shown) in association with the position in the longitudinal direction and the position in the width direction of the optical member sheet FX.
- the control device 190 acquires the optical axis data (inspection data of the in-plane distribution of the optical axis) of each inspection point CP from the storage device, and the optical member sheet FX (cut line CL) of the portion from which the sheet piece FXm is cut out.
- the direction of the average optical axis of the area defined by (1) is detected.
- the shift angle is calculated, for example, with the counterclockwise direction being positive and the clockwise direction being negative with respect to the edge line EL of the sheet piece FXm.
- seat FX detected by said method may make a desired angle with respect to one side of the display area P4 of the optical display component P.
- the bonding position (relative bonding position) of the piece FXm is determined. For example, when the direction of the optical axis of the optical member is set to 90 ° with respect to one side of the display region P4 according to the design specifications, the average optical axis direction of the optical member sheet FX is the display region.
- the sheet piece FXm is bonded to the optical display component P so as to form 90 ° with respect to one side of P4.
- the detection device 189 shown in FIG. 11A detects the cut line WCL of the sheet piece FXm

Abstract
Description
本出願は、2014年7月9日に日本に出願された特願2014-141317号に基づき、優先権を主張し、その内容をここに援用する。
特許文献1の装置は、長尺状のシート材を所定サイズにカットしてヘッドに保持する。そして、特許文献1の装置は、ヘッドを被貼付物が載置されたステージに移動させ、ヘッドと被貼付物とを位置決めした後、ヘッドを被貼付物上に押し付けてシート材を被貼付物に転写する。
よって、製品品質を高めることができない。
以下、図1から図8を用いて、本発明の第一の実施の形態に係る貼合装置及び光学表示デバイスの生産システムを説明する。
本実施形態の貼合装置100は、光学表示部品Pの一面に、長尺状の光学部材シートFXをハーフカットして得られたシート片F1Xを貼合する。
ヘッド本体部121は、上面が平坦な面となっており、下面が下側に凸となるように、光学部材シートFXの進行方向に沿って湾曲した曲面となっている。ヘッド本体部121の下面には、粘着シート122が固着される。粘着シート122としては、例えば、粘着性のシリコーンゴムなどが用いられる。粘着シート122の表面は、シート片F1Xを貼着して保持する湾曲した保持面122aとなっている。保持面122aは、例えば、シート片F1Xの貼合面(粘着層F2a)よりも弱い貼着力を有し、シート片F1Xの表面保護フィルムF4aを繰り返し貼着、剥離することが可能とされる。
図2は、集塵装置10の周辺の斜視図である。図3は、集塵装置10の周辺の平面図である。図4は、集塵装置10の側面図である。
以下、一対の第一ロール11a,11bのうち、シート片F1Xを挟んで上側に配置された第一ロールを第一上側ロール11aという。一対の第一ロール11a,11bのうち、シート片F1Xを挟んで下側に配置された第一ロールを第一下側ロール11bという。尚、第一上側ロール11a、第一下側ロール11bを、それぞれ単に第一ロールということがある。
尚、第一ロール対11の配置位置はこれに限らない。第一ロール対11の配置位置は、カット部115とヘッドユニット150との間であれば、適宜所望の位置に設定することができる。
以下、一対の第二ロール12a,12bのうち、第一上側ロール11aと対向する第二ロールを第二上側ロール12aという。一対の第二ロール12a,12bのうち、第一下側ロール11bと対向する第二ロールを第二下側ロール12bという。尚、第二上側ロール12a、第二下側ロール12bを、それぞれ単に第二ロールということがある。
本実施形態に係る貼合方法は、光学表示部品にシート片F1Xを貼合する貼合方法であって、巻き出しステップと、カットステップと、貼合ステップと、集塵ステップと、を含む。
カットステップは、光学部材シートFXを、セパレータシートF3aを残して切断することでシート片F1Xを形成する。
貼合ステップは、シート片F1XをセパレータシートF3aから剥がして光学表示部品に貼合する。
集塵ステップは、カットステップと貼合ステップとの間に、より好ましくはシート片F1Xを貼合ヘッド120の保持面122aに貼着するまでの間に、シート片F1Xの塵埃を除去する。
図2から図4に示すように、集塵ステップは、貼合ステップに搬送されるシート片F1Xの搬送方向における一部を上下から挟み、且つ、表面をシート片F1Xの表面に接触させてシート片F1Xの塵埃を除去する一対の第一ロール11a,11bによって構成される、第一ロール対11を用いる。第一ロール11a,11bのそれぞれの表面は、シート片F1Xの塵埃を除去可能な第一の粘着力As1を有する。
これにより、貼合ステージ171に保持された光学表示部品Pと貼合ヘッド120に保持されたシート片F1Xとの相対貼合位置が調整される。
また、第一ロール対11による接触式の構成であるため、非接触式の構成に比べて、シート片F1Xの表面の塵埃を効果的に除去することができる。
例えば、一対の第一ロール11a,11bのうち、第一上側ロール11aの表面のみが前記第一の粘着力As1を有していてもよいし、第一下側ロール11bの表面のみが前記第一の粘着力As1を有していてもよい。すなわち、一対の第一ロール11a,11bのうち、少なくとも一方の表面が前記第一の粘着力As1を有していればよい。但し、表面保護フィルムF4aの表面及びセパレータシートF3aの表面(下面)のそれぞれの塵埃を除去する観点からは、第一ロール11a,11bのそれぞれの表面が前記第一の粘着力As1を有することが好ましい。
一対の第一ロール11a,11bのうち一方の表面のみが第一の粘着力Fs1を有する場合には、一対の第二ロール12a,12bのうち、前記第一の粘着力Fs1を有する第一ロールと対向する第二ロールの表面のみが、前記第二の粘着力Fs2を有していてもよい。
また、第一貼合装置1002は、静止した第一シート片に対して貼合ヘッドの湾曲した保持面を押し付けながら保持面の湾曲に沿って貼合ヘッドを転動することにより、第一シート片をセパレータシートから剥離して保持面に保持するものである。そのため、第一シート片を光学表示部品Pに貼合する際に、第一シート片と光学表示部品Pとの間に気泡が発生することが抑制される。
また、第二貼合装置1003は、静止した第二シート片に対して貼合ヘッドの湾曲した保持面を押し付けながら、保持面の湾曲に沿って貼合ヘッドを転動することにより、第二シート片をセパレータシートから剥離して保持面に保持するものである。そのため、第二シート片を光学表示部品Pに貼合する際に、第二シート片と光学表示部品Pとの間に気泡が発生することが抑制される。
また、第三貼合装置1005は、静止した第三シート片に対して貼合ヘッドの湾曲した保持面を押し付けながら、保持面の湾曲に沿って貼合ヘッドを転動することにより、第三シート片をセパレータシートから剥離して保持面に保持するものである。そのため、第三シート片を光学表示部品Pに貼合する際に、第三シート片と光学表示部品Pとの間に気泡が発生することが抑制される。
以下、図9及び図10を用いて、第一の実施の形態の第一の変形例に係る集塵装置20を説明する。
図9は、第一の実施の形態の第一の変形例に係る集塵装置20の側断面図である。図10は、図9の要部拡大図である。
また、本変形例によれば、集塵装置20でレーザー加工によって生じるヒュームを、切断線SXの全長に亘って漏れなく吸引することができる。これにより、製品表面へのヒュームの付着を抑えると共に、製品に付着したヒュームによるライン汚染を防ぐことができる。
以下、図11から図13を用いて、本発明の第二の実施の形態に係る貼合装置及び光学表示デバイスの生産システムを説明する。
