For example, in the RTP method for manufacturing a liquid crystal optical display device, an optical display device is generally manufactured by the following method.

這如圖2所示，首先，在從R1送出的包含於帶狀的第1光學薄膜層積體中的第1載體薄膜上，將具有對應長方形的液晶面板的一面的寬度或長度的寬度或長度的以長邊朝向第1載體薄膜的寬度方向的方式被連續支持的第1光學薄膜片材，貼合至前述液晶面板的前述一面，且在從R2送出的包含於帶狀的第2光學薄膜層積體中的第2載體薄膜上，將具有對應前述液晶面板的另一面的寬度或長度的寬度或長度的以長邊朝向第2載體薄膜的長邊方向的方式被連續支持的第2光學薄膜片材，貼合至前述液晶面板的前述另一面。This is shown in FIG. 2. First, on the first carrier film included in the first optical film layered body having a strip shape sent from R1, a width or length of one side of the liquid crystal panel having a rectangular shape or The first optical film sheet having a length that is continuously supported such that the long side of the first carrier film faces the width direction of the first carrier film is bonded to the aforementioned side of the liquid crystal panel, and the second optical film included in the strip shape is sent from R2.

The optical film sheet is bonded to the other side of the liquid crystal panel.

藉此，第1及第2光學薄膜片材分別從第1及第2載體薄膜剝離，同時相互以呈正交偏光關係的方式，在液晶面板的兩面層積，藉此將層積體的光學顯示裝置連續製造。Thereby, the first and second optical film sheets are peeled from the first and second carrier films, respectively, and at the same time, they are laminated on both sides of the liquid crystal panel in a manner of orthogonal polarization relationship with each other, thereby optically laminating the laminated body.

最初說明關於表示本發明的特徵的圖6的實施例與比較例資料的工程能力指數Cp 值。工程能力指數Cp 值為在工業製品的品質管理領域中，作為將某工程的工程能力定量地評價指標的一個而習知的值。通常用以下的式子來定義。 　　Cp =(USL-LSL)/(6×δ) 　　其中，USL為上側規格值、LSL為下側規格值、+δ為母標準差的推定值，該等值為在母集團將特性值作為正規分佈而假定的值。Initially, the engineering capability index C p of the data of the example and the comparative example of FIG. 6 showing the characteristics of the present invention will be described. The engineering capability index C p value is a value known as an index for quantitatively evaluating the engineering capability of a certain project in the field of quality management of industrial products. It is usually defined by the following formula. C p = (USL-LSL) / (6 × δ) where USL is the upper specification value, LSL is the lower specification value, and + δ is the estimated value of the standard deviation of the mother. These values are the characteristic values in the parent group as Normally assumed value.

工程能力指數CP 值通常期望以表示具有越大的數字的能力來定義，0附近的值表示偏差過大，作為製品無法成為品質管理對象。較佳為Cp ＞1.33。Cp ＞1.67時到達承認標準，因此較佳。Cp ＜1.33時製造的製品群無法評價達到標準基準，因為未達到當初的目標品質，成為未滿足製品出貨基準者。The value of the engineering capability index C P is generally expected to be defined as a capability having a larger number, and a value near 0 indicates that the deviation is too large and cannot be a target of quality management as a product. Preferably, C p > 1.33. When C p > 1.67, the recognition standard is reached, so it is preferable. The product group manufactured when C p <1.33 cannot be evaluated to meet the standard benchmark, because it did not meet the original target quality and became the one who did not meet the product shipment benchmark.

本發明的裝置包含：當第2光學薄膜片材11的前端部1110到達預定的第2檢出位置71時，停止第2載體薄膜31的運送，檢出構成第2光學薄膜片材11的長邊方向的側端部111的長邊y11的一方的兩端位置的前端112的第3檢出機構711及檢出後端113的第4檢出機構712；基於側端部111的兩端位置資訊114，將液晶面板5的另一面51與第2光學薄膜片材11對位的第2對位機構81；將第2光學薄膜片材11從第2載體薄膜31剝離的第2剝離機構61；將剝離的第2光學薄膜片材11貼合至液晶面板5的另一面51的第2貼合機構91。The apparatus of the present invention includes: when the front end portion 1110 of the second optical film sheet 11 reaches a predetermined second detection position 71, stopping the conveyance of the second carrier film 31 and detecting the length of the second optical film sheet 11 The third detection mechanism 711 of the front end 112 and the fourth detection mechanism 712 of the rear end 113 of the long side y11 of one of the two sides of the long side y11 of the lateral end portion 111; based on the positions of the two ends of the side end 111 Information 114, a second alignment mechanism 81 that aligns the other surface 51 of the liquid crystal panel 5 with the second optical film sheet 11; a second peeling mechanism 61 that peels the second optical film sheet 11 from the second carrier film 31 A second bonding mechanism 91 for bonding the peeled second optical film sheet 11 to the other surface 51 of the liquid crystal panel 5.

裝設於本發明的方法及裝置的一對帶狀的光學薄膜層積體R1及R2，如圖1的(a)及(b)所示，具有對應長方形的液晶面板5的長邊A或短邊B的寬度。在第1搬送線110中，朝向第1貼合位置100液晶面板5將長邊A作為前端面搬送。因此，貼合於液晶面板5的一面50的第1光學薄膜片材10，因為其長邊y10對應液晶面板5的長邊A的例如對準標記，在第1載體薄膜30之上以向寬度方向的方式被連續支持，從第1載體薄膜30剝離，同時被送至第1貼合位置100。此時，將構成剝離的第1光學薄膜片材10的前端面的寬度方向的一端102及另一端103，以相對於設定在由例如CCD攝影機所構成的2個檢出機構，具體來說，以相對於設定在第1攝像裝置701及第2攝像裝置702的水平基準位置的偏差角度θ1作為寬度方向的位置資料算出，被搬送液晶面板5以修正偏差角度θ1的方式控制姿勢。As shown in (a) and (b) of FIG. 1 (a) and (b), a pair of strip-shaped optical film laminates R1 and R2 installed in the method and device of the present invention have a long side A or The width of the short side B. In the first conveying line 110, the liquid crystal panel 5 conveys the long side A as the front end surface toward the first bonding position 100. Therefore, the first optical film sheet 10 bonded to one side 50 of the liquid crystal panel 5 has a long side y10 corresponding to, for example, an alignment mark on the long side A of the liquid crystal panel 5, and has a width on the first carrier film 30. The directional method is continuously supported, peeled from the first carrier film 30, and sent to the first bonding position 100 at the same time. At this time, one end 102 and the other end 103 in the width direction of the front end surface of the peeled first optical film sheet 10 are set relative to two detection mechanisms configured by, for example, a CCD camera, specifically, The deviation angle θ1 from the horizontal reference positions set in the first imaging device 701 and the second imaging device 702 is calculated as position data in the width direction, and the conveyed liquid crystal panel 5 controls the posture so as to correct the deviation angle θ1.

另一方面，在第2搬送線210中，朝向第2貼合位置200液晶面板5將短邊B作為前端面搬送。因此，貼合於液晶面板5的另一面51的第2光學薄膜片材11，因為其長邊y11對應液晶面板5的長邊A的例如對準標記，在第2載體薄膜31之上以朝向長邊方向的方式被連續支持，從第2載體薄膜31剝離，同時被送至第2貼合位置200。此時，為了一樣算出第1搬送線110的貼附精度，將構成剝離的第2光學薄膜片材11的前端部1110的任一者的側端部111的長邊y11的前端112及後端113，以相對於設定在由例如CCD攝影機所構成的2個檢出機構，具體來說，以相對於設定在第3攝像裝置711及第4攝像裝置712的垂直基準位置的偏差角度θ2作為長邊方向的位置資料算出，被搬送液晶面板5以修正偏差角度θ2的方式控制姿勢。On the other hand, in the second transfer line 210, the liquid crystal panel 5 is transported with the short side B as the front end surface toward the second bonding position 200. Therefore, the second optical film sheet 11 bonded to the other surface 51 of the liquid crystal panel 5 has a long side y11 corresponding to, for example, an alignment mark on the long side A of the liquid crystal panel 5, and is oriented on the second carrier film 31. The method in the long-side direction is continuously supported, peeled from the second carrier film 31, and sent to the second bonding position 200 at the same time. At this time, in order to calculate the attachment accuracy of the first conveying line 110 in the same manner, the front end 112 and the rear end of the long side y11 of the side end portion 111 constituting any one of the front end portions 1110 of the second optical film sheet 11 to be peeled off. 113. The deviation angle θ2 from the vertical reference positions set to the third imaging device 711 and the fourth imaging device 712 is set to be long with respect to two detection mechanisms set by, for example, a CCD camera. The lateral position data is calculated, and the conveyed liquid crystal panel 5 controls the posture so as to correct the deviation angle θ2.

以此方式，本發明，相對於液晶面板5的兩面的第1及第2光學薄膜片材的貼合，在分別貼合至液晶面板5的兩面之前將對應液晶面板的長邊A或短邊B的構成寬度不同的第1光學薄膜片材10及第2光學薄膜片材11的前端部的寬度方向及長邊方向的各長邊y10及長邊y11在2個地方讀取，在一方算出相對於水平基準位置的偏差角度θ1，在另一方算出相對於垂直基準位置的偏差角度θ2，基於此等控制液晶面板5的姿勢，藉此實現在液晶面板5的兩面以高貼附精度貼合。In this way, according to the present invention, the lamination of the first and second optical film sheets on both sides of the liquid crystal panel 5 corresponds to the long side A or the short side of the liquid crystal panel before being attached to the two sides of the liquid crystal panel 5 respectively. Each of the first optical film sheet 10 and the second optical film sheet 11 having different configuration widths in the width direction and the long side direction of the front end portions of the first optical film sheet 10 and the long side y10 and the long side y11 is read at two places and calculated on one side. The deviation angle θ1 with respect to the horizontal reference position is calculated on the other side, and the deviation angle θ2 with respect to the vertical reference position is calculated on the other side, and the posture of the liquid crystal panel 5 is controlled based on these, thereby achieving high-precision bonding on both sides of the liquid crystal panel 5 .

本發明的特徵，如圖7所示，從將檢出構成第1光學薄膜片材10的前端部1010的長邊y10、及構成第2光學薄膜片材11的前端部1110的長邊y11的實施例(a)、與同樣檢出構成第1光學薄膜片材10的前端部1010的長邊y10、及僅檢出構成第2光學薄膜片材11的前端部1110的短邊x11的比較例(b)進行比較的工程能力指數Cp 值的資料變得明確。A feature of the present invention is that, as shown in FIG. 7, the long side y10 constituting the front end portion 1010 of the first optical film sheet 10 and the long side y11 constituting the front end portion 1010 of the second optical film sheet 11 are detected. Example (a), a comparative example in which the long side y10 constituting the front end portion 1010 of the first optical film sheet 10 and the short side x11 constituting only the front end portion 1110 of the second optical film sheet 11 were detected in the same manner. (b) The data of the comparative engineering capability index C p value becomes clear.

如圖6的表所示，僅在2個地方檢出前端位置進行對位的由RTP方式製造從前型的光學顯示裝置的層積體的方法及裝置， 　　全部基於比較例(b)的方法進行。從圖6之例的資料來看，將液晶面板5的一面50對位至構成第1光學薄膜片材10的寬度方向的長邊y10並貼合時的Cp ，貼合開始之時與貼合結束之時都是Cp ＞1.67，在驅動側及操作側也都是Cp ＞1.33。相對於此，將液晶面板5的另一面51對位至構成第2光學薄膜片材11的寬度方向的短邊x10並貼合時Cp ，平均值比1.00還低，貼合開始之時與貼合結束之時都是Cp ＜1.33，到驅動側及操作側是Cp ＜1.00，顯示在從前型的製造光學顯示裝置的層積體的方法及裝置，僅基於僅包含構成寬度方向的短邊x10的2個地方的檢出資料並無法進行液晶面板5與光學薄膜片材間的對位。As shown in the table of FIG. 6, the method and apparatus for manufacturing a laminated body of a front-type optical display device by the RTP method by detecting the position of the front end only at two places and performing the alignment are performed based on the method of Comparative Example (b). . From the data of the example in FIG. 6, C p at the time of lamination is aligned with one side 50 of the liquid crystal panel 5 aligned to the long side y10 constituting the width direction of the first optical film sheet 10, and the lamination is started at the time of lamination. At the end of closing, both C p > 1.67, and both C p > 1.33 on the drive side and the operation side. On the other hand, when the other side 51 of the liquid crystal panel 5 is aligned to the short side x10 constituting the width direction of the second optical film sheet 11 and bonded C p , the average value is lower than 1.00. At the end of lamination, C p <1.33, C p <1.00 to the driving side and the operating side. The method and device for manufacturing a laminated body of an optical display device from the previous model are based only on the method that includes only the width direction. The detection data of the two places on the short side x10 cannot perform alignment between the liquid crystal panel 5 and the optical film sheet.

此外，在專利文獻1及專利文獻2中，雖揭示檢出光學薄膜片材前端的邊緣檢出裝置與液晶面板的對準標記的檢出裝置，但完全未揭示本發明所實現的與液晶面板的兩面同等的高貼附精度的想法。In addition, although Patent Document 1 and Patent Document 2 disclose a detection device that detects an edge detection device at the leading end of an optical film sheet and an alignment mark of a liquid crystal panel, it does not disclose a liquid crystal panel implemented by the present invention. Both sides have the same idea of high attach accuracy.

又根據專利文獻3，揭示將在貼合位置之前從載體薄膜剝離的光學薄膜片材的寬度方向的兩端位置，以例如由CCD攝影機所構成的2個攝像裝置檢出，基於該檢出資料調整光學薄膜片材的前端位置，此外在另一方讀取對應的面板構件的前端位置，將面板構件進行位置調整並貼合至剝離的光學薄膜片材。不過，在專利文獻3中，與專利文獻1及專利文獻2一樣，完全未揭示僅讀取構成寬度不同的第1及第2光學薄膜片材的前端的長邊，算出相對於水平基準位置及垂直基準位置的各自的偏差角度，基於其等控制液晶面板的姿勢的想法。根據專利文獻3，檢出構成光學薄膜片材的前端面的短邊的兩端位置時，從圖6的資料可明白不可能實現本發明的這種高貼附精度。According to Patent Document 3, the two positions in the width direction of the optical film sheet to be peeled from the carrier film before the laminating position are detected by two imaging devices including a CCD camera, for example, and based on the detected data The position of the front end of the optical film sheet is adjusted, and the position of the front end of the corresponding panel member is read on the other side, and the position of the panel member is adjusted and bonded to the peeled optical film sheet. However, in Patent Document 3, as in Patent Documents 1 and 2, it is not disclosed at all that only the long sides of the front ends of the first and second optical film sheets having different constitutional widths are read, and the calculation with respect to the horizontal reference position and The deviation angles of the vertical reference positions are based on the idea of controlling the posture of the liquid crystal panel. According to Patent Document 3, when the positions of both ends of the short side constituting the front end surface of the optical film sheet are detected, it can be understood from the data of FIG. 6 that it is impossible to achieve such high attachment accuracy of the present invention.

從圖6及圖7可明白，即便僅以在專利文獻1～3揭示的短邊的位置資料寬度方向的2點位置資訊控制液晶面板5的姿勢在液晶面板5的兩面合第1及第2光學薄膜片材，也無法實現一樣的貼附精度。As can be understood from FIGS. 6 and 7, even if the position information of the liquid crystal panel 5 is controlled by only two position information in the width direction of the short side position data disclosed in Patent Documents 1 to 3, the first and second sides of the liquid crystal panel 5 are combined. Optical film sheets cannot achieve the same attaching accuracy.

專利文獻4，雖揭示在由RTP方式製造光學顯示裝置的層積體的方法及裝置中，於貼合至基板前檢出光學薄膜片材的相當的薄膜片的前端的檢出機構，但並未揭示在液晶面板的兩面貼合寬度不同的第1光學薄膜片材及第2光學薄膜片材的想法。又在專利文獻5中，僅記載讀取光學薄膜片材的前端部的兩端位置的工程，完全未記載於液晶面板的兩面貼合寬度不同的第1光學薄膜片材及第2光學薄膜片材，這不過是構成專利文獻3記載的光學薄膜片材的前端部的寬度方向的兩端位置的檢出機構而已。Patent Document 4 discloses a method and apparatus for manufacturing a laminated body of an optical display device by the RTP method, and a detection mechanism for detecting a leading end of a corresponding thin film sheet of an optical thin film sheet before being bonded to a substrate. The idea of laminating the first optical film sheet and the second optical film sheet with different widths on both sides of the liquid crystal panel is not disclosed. Furthermore, in Patent Document 5, the process of reading only the positions of both ends of the front end portion of the optical film sheet is described, and the first optical film sheet and the second optical film sheet having different bonding widths on both sides of the liquid crystal panel are not described at all. This is nothing more than a detection mechanism that constitutes both ends in the width direction of the front end portion of the optical film sheet described in Patent Document 3.

以上，在RTP方式中製造的光學顯示裝置的層積體6，在液晶面板5的一面50及另一面51貼合第1光學薄膜片材10及第2光學薄膜片材11時，僅讀取構成寬度不同的第1光學薄膜片材10及第2光學薄膜片材11的前端的各自的長邊y10、y11的兩端，基於該等2個地方的兩端位置資訊控制液晶面板5的姿勢，藉此實現相對於液晶面板5的兩面的第1光學薄膜片材10及第2光學薄膜片材11的貼附精度。因此，本發明為了實現高貼附精度，不依據3點以上的位置資訊而僅以2個地方的位置資訊，實現與其同等的貼附精度，不配置提高製造工程上的故障機率的多數檢出機構，能藉由最小限度的檢出機構實現高貼附精度。As described above, when the laminated body 6 of the optical display device manufactured by the RTP method is bonded to the first optical film sheet 10 and the second optical film sheet 11 on one surface 50 and the other surface 51 of the liquid crystal panel 5, only reading is performed. The ends of the respective long sides y10 and y11 of the front ends of the first optical film sheet 10 and the second optical film sheet 11 having different widths are configured, and the posture of the liquid crystal panel 5 is controlled based on the position information of the two ends at the two ends. As a result, the accuracy of attaching the first optical film sheet 10 and the second optical film sheet 11 to both sides of the liquid crystal panel 5 is achieved. Therefore, in order to achieve high attaching accuracy, the present invention does not rely on position information of more than 3 points and only uses 2 pieces of positional information to achieve equivalent attaching accuracy, and does not configure a majority of detections that increase the probability of failure in manufacturing processes The mechanism can achieve high attaching accuracy with a minimum detection mechanism.

雖藉由實施例及圖式說明本發明，但本發明並不限定於此，本發明所屬技術領域具有通常知識者，在本發明的技術思想以及以下記載的申請專利範圍內，當然能進行各種修改及變形。Although the present invention is described by way of examples and drawings, the present invention is not limited to this.
