A process of attaching a polarizing film to the element substrate 1.
第四圖係繪示先前之將偏光膜附著於液晶元件基板上之工程概略之第一剖面工程圖。第五圖係繪示先前之將偏光膜附著於液晶元件基板上之工程概略之第二剖面工程圖。 The fourth drawing shows a first cross-sectional engineering drawing of the prior art in which the polarizing film is attached to the liquid crystal element substrate. The fifth drawing shows a second cross-sectional engineering drawing of the prior art in which the polarizing film is attached to the liquid crystal element substrate.
偏光膜附著工程係液晶元件組裝工程後進行之工程。如第四圖所示，為了於液晶元件基板1第一主表面側佈置偏光膜2而將偏光膜2一表面之粘貼層露出，從偏光膜2上脫離脫模用膜2a。 The polarizing film adhesion engineering is a project carried out after the assembly of the liquid crystal element. As shown in the fourth figure, in order to expose the polarizing film 2 on the first main surface side of the liquid crystal element substrate 1, the adhesive layer on one surface of the polarizing film 2 is exposed, and the release film 2a is released from the polarizing film 2.
然後，如第五圖所示，於液晶元件基板1側傾斜設置台2A上所吸附及固定之偏光膜2，並且一邊將 液晶元件基板1及偏光膜2送到搬送輥5，一邊於液晶元件基板1第一主表面(CF螢幕)緊貼偏光膜2。 Then, as shown in FIG. 5, the polarizing film 2 adsorbed and fixed on the stage 2A is obliquely disposed on the liquid crystal element substrate 1 side, and one side will be The liquid crystal element substrate 1 and the polarizing film 2 are sent to the transport roller 5, and are in close contact with the polarizing film 2 on the first main surface (CF screen) of the liquid crystal element substrate 1.
然後，翻轉液晶元件基板1後，於液晶元件基板1之第二主表面(TFT螢幕)亦相似地附著偏光膜3。 Then, after the liquid crystal element substrate 1 is turned over, the polarizing film 3 is similarly attached to the second main surface (TFT screen) of the liquid crystal element substrate 1.
然而，先前之偏光膜附著於液晶元件基板上之方法，存在由於液晶元件基板與偏光膜之間空氣而產生氣泡之可能性較高之問題。這是因為第五圖所示沒有放在設置台上之偏光膜一部分，很難維持平坦直線，而朝下彎曲，相當於偏光膜附著開始部位之偏光膜右側角落與、液晶元件基板右側角落則發生翹起。 However, in the method in which the polarizing film of the prior art is attached to the liquid crystal element substrate, there is a possibility that bubbles are generated due to air between the liquid crystal element substrate and the polarizing film. This is because the part of the polarizing film that is not placed on the mounting table shown in the fifth figure is difficult to maintain a flat straight line, and is bent downward, which corresponds to the right corner of the polarizing film at the beginning of the polarizing film attachment and the right corner of the liquid crystal element substrate. Occurred.
並且，根據先前之附著偏光膜方法，於設置台2A上偏光膜附著得較輕，此時搬送輥5進行旋轉，由於其端部附著於液晶元件基板1與附著於液晶元件基板1上之偏光膜2，受到箭頭方向之移動力，於偏光膜2上整體上產生拉伸應力，偏光膜2就被拉長，由於拉長之偏光膜2長度，拉長之偏光膜2總長比要附著之液晶元件基板1長度稍長，其結果引發於液晶元件基板1上發生彎曲之問題。 Further, according to the prior method of attaching the polarizing film, the polarizing film adheres lightly on the mounting table 2A, and the conveying roller 5 rotates at this time, and the end portion thereof adheres to the liquid crystal element substrate 1 and the polarized light attached to the liquid crystal element substrate 1. The film 2 is subjected to a moving force in the direction of the arrow, and tensile stress is generated on the polarizing film 2 as a whole, and the polarizing film 2 is elongated. Due to the length of the elongated polarizing film 2, the length of the elongated polarizing film 2 is to be attached. The liquid crystal element substrate 1 has a slightly longer length, and as a result, it causes a problem that the liquid crystal element substrate 1 is bent.
本發明係為了解決如上所述先前之將偏光膜附著於液晶元件基板上之方法所存在問題而研究出，其目的在於提供一種偏光膜附著裝置，其特徵在於，一改以前於設置台上吸附偏光膜大部分面積而其前部則露於設置台外之方式，於左右之傾斜輥與固定輥上設置履帶式粘附板，且於形成整體平坦粘附板之上面之粘附膜 上，佈置偏光膜後，將偏光膜附著於液晶元件基板上，從而偏光膜整體上不發生彎曲，從而當偏光膜附著於液晶元件基板表面上時，氣泡之產生可能性顯著降低，從而沒有不合格產品產生之可能性，並且能夠防止由於偏光膜拉長而液晶元件基板發生彎曲現象。 The present invention has been made in order to solve the above problems in the method of attaching a polarizing film to a liquid crystal element substrate as described above, and an object thereof is to provide a polarizing film attaching apparatus, which is characterized in that it is adsorbed on a setting stage before being modified. The polarizing film has a large area and the front portion is exposed outside the set table, and the crawler type adhesive sheet is disposed on the left and right inclined rolls and the fixed roll, and the adhesive film is formed on the upper flat adhesive sheet. When the polarizing film is disposed, the polarizing film is attached to the liquid crystal element substrate, so that the polarizing film does not bend as a whole, and when the polarizing film adheres to the surface of the liquid crystal element substrate, the possibility of generation of bubbles is remarkably lowered, so that there is no The possibility of occurrence of a qualified product and prevention of bending of the liquid crystal element substrate due to elongation of the polarizing film can be prevented.
為實現該目的，根據本發明之偏光膜附著裝置，作為將偏光膜附著於液晶元件基板表面之偏光膜附著裝置，其特徵在於，該偏光膜附著裝置係包括：在其底面吸附該液晶元件基板狀態下進行移送之面板搬送板；放置該偏光膜之粘附板，該粘附板係以履帶式相連狀態下，其兩側設置於傾斜輥與固定輥上，該傾斜輥為了於該液晶元件基板上附著該偏光膜，而朝上移動，從而與該面板搬送板所吸附之液晶元件基板相接觸，其特徵在於，該粘附板之內側由聚四氟乙烯玻璃纖維板形成，外側則由粘附膜形成，其特徵在於，該傾斜輥與藉由伺服驅動器進行驅動之傾斜動力部相連，從而上下移動，其特徵在於，該傾斜輥與該固定輥係設計成無需藉助原動力即可旋轉(轉動)，該傾斜輥朝上移動，從而該偏光膜之端部附著於該液晶元件基板端部之狀態下，該液晶元件基板係藉由該面板搬送板移動，同時一邊該偏光膜逐漸附著於該液晶元件基板上，一邊該傾斜輥及該固定輥進行旋轉。 In order to achieve the object, a polarizing film adhering device according to the present invention is a polarizing film attaching device for attaching a polarizing film to a surface of a liquid crystal element substrate, wherein the polarizing film attaching device includes: adsorbing the liquid crystal element substrate on a bottom surface thereof a panel conveying plate that is transferred in a state; an adhesive sheet on which the polarizing film is placed, the adhesive sheet is connected in a crawler belt state, and both sides thereof are disposed on the inclined roller and the fixed roller, and the inclined roller is used for the liquid crystal element The polarizing film is attached to the substrate and moved upward to contact the liquid crystal element substrate adsorbed by the panel transporting plate. The inner side of the adhesive sheet is formed of a PTFE fiberglass board, and the outer side is made of a sticky layer. The film forming is characterized in that the inclined roller is connected to the tilting power portion driven by the servo driver to move up and down, wherein the tilting roller and the fixed roller are designed to be rotated without rotating the motive force (rotation) The tilting roller is moved upward so that the end portion of the polarizing film is attached to the end portion of the liquid crystal element substrate, and the liquid crystal element Plate-based panel by the transfer plate moves while gradually while the polarized film attached to the liquid crystal cell substrate, while the inclined roller and the fixing roller rotates.
根據本發明之偏光膜附著裝置係，一改以前於設置台上吸附偏光膜大部分面積，而首先粘合於液晶元件基板之偏光膜前部則露於設置台外之方式，於左右所設傾斜輥與固定輥上，以履帶式設置粘附板，並於粘附板上面佈置偏光膜後，朝上方傾斜輥而緊貼於液晶元件基板，一邊移動液晶元件基板，一邊於液晶元件基板上逐漸附著偏光膜，從而完全不發生偏光膜整體上彎曲現象，從而於偏光膜與液晶元件基板表面之間產生氣泡可能性顯著降低，具有這種效果。 According to the polarizing film attachment device of the present invention, the majority of the area of the polarizing film is adsorbed on the mounting table, and the front portion of the polarizing film which is first bonded to the liquid crystal element substrate is exposed outside the mounting table, and is disposed on the left and right sides. On the inclined roller and the fixed roller, an adhesive plate is provided in a crawler type, and a polarizing film is disposed on the adhesive plate, and then the roller is tilted upward to adhere to the liquid crystal element substrate, and the liquid crystal element substrate is moved while being on the liquid crystal element substrate. When the polarizing film is gradually attached, the entire polarizing film is not bent at all, and the possibility of generating bubbles between the polarizing film and the surface of the liquid crystal element substrate is remarkably lowered, which has such an effect.
並且，本發明中偏光膜附著於液晶元件基板上時，亦不發生偏光膜長度如先前技術一樣稍微拉長之問題，因此不發生液晶元件基板之彎曲。當偏光膜逐漸附著於液晶元件基板上時，傾斜輥亦朝液晶元件基板之移動方向旋轉，因此粘附板與液晶元件基板之移動速度相同速度移動，因此偏光膜上完全不發生拉伸應力。因此，設有偏光膜之液晶元件基板之不合格率顯著降低，並且生產費用等諸多費用顯著減少，具有這種效果。 Further, in the present invention, when the polarizing film is attached to the liquid crystal element substrate, the length of the polarizing film is not elongated as in the prior art, and thus the liquid crystal element substrate is not bent. When the polarizing film gradually adheres to the liquid crystal element substrate, the inclined roller also rotates in the moving direction of the liquid crystal element substrate. Therefore, the adhesive sheet moves at the same speed as the moving speed of the liquid crystal element substrate, and thus the tensile stress does not occur at all on the polarizing film. Therefore, the failure rate of the liquid crystal element substrate provided with the polarizing film is remarkably lowered, and the cost of production and the like are remarkably reduced, and this effect is obtained.

參照第六圖，根據本發明之粘附板30上面，放偏光膜2狀態下，於放置偏光膜2之位置上面，佈置 將液晶元件基板1所吸附之搬送板40。 Referring to the sixth drawing, the adhesive sheet 30 according to the present invention is arranged on the upper surface of the polarizing film 2 in the state where the polarizing film 2 is placed. The transfer plate 40 to which the liquid crystal element substrate 1 is attached is attached.
本發明之粘附板30，由聚四氟乙烯與位於聚四氟乙烯板上面的粘附膜構成。 The adhesive sheet 30 of the present invention is composed of polytetrafluoroethylene and an adhesive film on the surface of the polytetrafluoroethylene sheet.
本發明之搬送板40，藉由馬達等動力裝置(未繪示)朝箭頭方向(參照第二圖)移動，根據本發明之傾斜輥20能夠調整為上下傾斜，從而與搬送板40所吸附之液晶元件基板1相接觸，固定輥22則設計成其位置固定而不上下移動。 The conveying plate 40 of the present invention is moved in the direction of the arrow (see the second drawing) by a power unit (not shown) such as a motor, and the inclined roller 20 according to the present invention can be adjusted to be inclined up and down so as to be adsorbed by the conveying plate 40. The liquid crystal element substrate 1 is in contact with each other, and the fixed roller 22 is designed to be fixed in position without moving up and down.

圖中繪示了只有一個傾斜輥20與固定輥22的，實際上各個輥子之直徑較大，其所占面積亦變大，因此實際上傾斜輥20與固定輥22用一個以上輥子而成。 The figure shows that there is only one inclined roller 20 and the fixed roller 22. In fact, the diameter of each roller is large, and the area occupied by the roller is also large. Therefore, the inclined roller 20 and the fixed roller 22 are actually formed of one or more rollers.
由於粘附板屬於消耗部件，為了進行更換，設有板連接部32。 Since the adhesive sheet belongs to a consumable part, a plate connecting portion 32 is provided for replacement.

第十二圖係用於說明按照先前方式將偏光膜附著於液晶元件基板上時之問題的例示圖。 Fig. 12 is a view for explaining an example of a problem when a polarizing film is attached to a liquid crystal element substrate in the prior art.
第十二圖中繪示之先前技術之例示圖係，繪示第五圖中繪示之先前將偏光膜附著於液晶元件基板上之工程中實際發生問題的圖。 The illustration of the prior art shown in FIG. 12 is a diagram showing a problem actually occurring in the process of attaching the polarizing film to the liquid crystal element substrate in the fifth drawing.
如第十二圖所示，先前之吸附於設置台2A上固定之偏光膜2中，露在設置台2A外部之部分，如第五圖所示不能維持一直線平整形狀，實際上存在朝一側傾斜之問題。 As shown in Fig. 12, the portion of the polarizing film 2 previously fixed to the mounting table 2A is exposed to the outside of the setting table 2A, and as shown in the fifth figure, the straight line shape cannot be maintained, and actually there is a tilt to one side. The problem.
如上所示，由於偏光膜2中露在設置台2A外部之部分朝上方或下方彎曲，因此該彎曲部分之偏光膜2不能與液晶元件基板1完全緊貼，從而於偏光膜2與液晶元件基板1之間產生氣泡，引發發生不合格產品之問題。 As described above, since the portion of the polarizing film 2 exposed outside the mounting table 2A is bent upward or downward, the polarizing film 2 of the bent portion cannot be completely in close contact with the liquid crystal element substrate 1, thereby the polarizing film 2 and the liquid crystal element substrate. Bubbles are generated between 1 and cause problems with defective products.
並且，根據先前之附著偏光膜方式，偏光膜2於設置台2A上吸附得較輕，此時搬送輥5旋轉，而液晶元件基板1與端部附著於液晶元件基板1上之偏光膜2，受箭頭方向之移動力，而於偏光膜2上整體上發生拉伸應力，從而偏光膜2亦被拉長，並由於拉長之偏光膜2長度，被拉長偏光膜2之整體長度比要附著之液晶元件基板1長度稍長，結果上引發液晶元件基板1發生彎曲之問題。 Further, according to the conventional method of attaching a polarizing film, the polarizing film 2 is adsorbed lightly on the mounting table 2A, and at this time, the conveying roller 5 is rotated, and the liquid crystal element substrate 1 and the end portion are attached to the polarizing film 2 on the liquid crystal element substrate 1, Due to the moving force in the direction of the arrow, tensile stress is generated as a whole on the polarizing film 2, so that the polarizing film 2 is also elongated, and the length of the polarizing film 2 is elongated due to the length of the elongated polarizing film 2. The attached liquid crystal element substrate 1 has a slightly longer length, and as a result, the liquid crystal element substrate 1 is caused to be bent.
第十三圖係用於克服第十二圖所示先前之附著偏光膜方式中問題之本發明特徵進行說明的說明圖。 Fig. 13 is an explanatory view for explaining the features of the present invention for overcoming the problems in the prior method of attaching the polarizing film shown in Fig. 12.
參照第十三圖，根據本發明之偏光膜附著裝置，於上下移動之傾斜輥20與固守所設位置之固定輥22上，設置履帶式移動之粘附板30。 Referring to Fig. 13, according to the polarizing film attachment device of the present invention, a crawler-type moving adhesive sheet 30 is provided on the inclined roller 20 which moves up and down and the fixed roller 22 which is fixed at the position.
根據本發明之液晶元件基板1以吸附於搬送板40上之狀態下，與搬送板40一同朝箭頭方向移動，並且佈置於液晶元件基板1上之偏光膜2放在粘附板30上面，傾斜輥20朝上傾斜，以使偏光膜2角落之端部與液晶元件基板1之角落端部相接觸之狀態下，隨著搬送板40與液晶元件基板40之箭頭方向移動，粘附於粘附板30上之偏光膜2，亦由於傾斜輥20逐漸旋轉而按壓液晶元件基板1，從而偏光膜之剩餘部分亦逐漸與液晶元件基板1粘合。 The liquid crystal element substrate 1 according to the present invention is moved in the direction of the arrow together with the transfer plate 40 in a state of being adsorbed on the transfer plate 40, and the polarizing film 2 disposed on the liquid crystal element substrate 1 is placed on the adhesive sheet 30, inclined The roller 20 is inclined upward so that the end portion of the corner of the polarizing film 2 is in contact with the corner end portion of the liquid crystal element substrate 1, and adheres to the adhesion in accordance with the direction of the arrow of the transporting plate 40 and the liquid crystal element substrate 40. The polarizing film 2 on the plate 30 is also pressed by the tilting roller 20 to press the liquid crystal element substrate 1, and the remaining portion of the polarizing film is gradually adhered to the liquid crystal element substrate 1.
根據本發明之傾斜輥20與固定輥22不使用馬達等驅動裝置，而採用無動力方式。 The inclined roller 20 and the fixed roller 22 according to the present invention do not use a driving device such as a motor, but employ an unpowered method.
粘附於粘附板30上之偏光膜2之液晶元件基板1中，要進行附著之表面上，塗抹粘合劑，因此於面板搬送板40上所吸附之液晶元件基板1朝箭頭方向移動，而無動力之傾斜輥20與固定輥22亦跟著旋轉。 In the liquid crystal element substrate 1 of the polarizing film 2 adhered to the adhesive sheet 30, an adhesive is applied to the surface to be adhered, so that the liquid crystal element substrate 1 adsorbed on the panel transporting plate 40 moves in the direction of the arrow. The unpowered tilting roller 20 and the fixed roller 22 are also rotated.
若傾斜輥20與固定輥22藉由另外設置之驅動裝置進行旋轉，那麼只有與搬送板40之移動速度與傾斜輥20及固定輥22之旋轉速度正確同步，才不會偏光膜附著於液晶元件基板1上時發生偏光膜2拉長或彎曲之不良。然而若有絲毫不協調，於液晶元件基板1上附著偏光膜2時不合格產品產生可能性增加。 If the inclined roller 20 and the fixed roller 22 are rotated by a separately provided driving device, the polarizing film is not attached to the liquid crystal element only when the moving speed of the conveying plate 40 and the rotating speed of the inclined roller 20 and the fixed roller 22 are correctly synchronized. When the substrate 1 is on the substrate 1, the polarizing film 2 is elongated or bent. However, if there is any slight dissonance, the possibility of occurrence of defective products increases when the polarizing film 2 is attached to the liquid crystal element substrate 1.
由於這個原因，根據本發明之傾斜輥20及固 定輥22係無動力驅動的。 For this reason, the inclined roller 20 and the solid according to the present invention The fixed roller 22 is unpowered.
並且，本發明中偏光膜2附著於液晶元件基板22上時，不會發生偏光膜2長度像先前技術一樣稍微拉長之問題，因此不發生液晶元件基板1之彎曲。當偏光膜2逐漸附著於液晶元件基板1上時，傾斜輥20朝著液晶元件基板1之移動方向旋轉，因此粘附板30與液晶元件基板1之移動速度相同速度移動，因此在偏光膜2完全不發生拉伸應力。 Further, in the present invention, when the polarizing film 2 is attached to the liquid crystal element substrate 22, the length of the polarizing film 2 is not elongated as in the prior art, and thus the liquid crystal element substrate 1 is not bent. When the polarizing film 2 is gradually attached to the liquid crystal element substrate 1, the inclined roller 20 is rotated toward the moving direction of the liquid crystal element substrate 1, and therefore the adhesive sheet 30 moves at the same speed as the moving speed of the liquid crystal element substrate 1, and thus the polarizing film 2 is Tensile stress does not occur at all.
最近彩色液晶顯示器越來越大型化，先前之彩色液晶顯示器大小主要係15英寸，現在主要使用30英寸、45英寸，以後彩色液晶顯示器之大小亦將持續大型化。 Recently, color liquid crystal displays have become larger and larger. Previously, color liquid crystal displays were mainly 15 inches in size, and now mainly used 30 inches and 45 inches, and the size of color liquid crystal displays will continue to be large.
