Description

1354150 « r Divided active correction correction date: 2011/3/11 VI. Description of the Invention: [Technical Field] The present invention relates to a polarizing film bonding apparatus and a liquid crystal display device having the same system. [Prior Art] In the past, liquid crystal display devices have been widely manufactured. In order to control the penetration or interruption of light, a substrate (liquid crystal panel) used for a liquid crystal display device is usually attached with a polarizing film. The polarizing film will conform to the absorption axis in a vertical direction. As a method of bonding a polarizing film to a substrate, a so-called chip t〇 Pand method in which a polarizing film is cut in accordance with the substrate size and then bonded is used. However, this method requires a polarizing film to be applied to the substrate one by one, which has the disadvantage of low production efficiency. On the other hand, other methods include a so-called continuous application of a polarizer to a substrate by a conveyor roller.

Roll to Panel mode. According to this method, it is possible to carry out the bonding with higher productivity. The manufacturing system of the optical display device in Patent Document 1 discloses an example of the Roll to Panel method. In the above manufacturing system, the optical film (polarizing film) is attached to the substrate, and then the substrate is rotated, and the polarizing film is bonded from the lower surface. Patent Document 1: Japanese Patent Laid-Open Publication No. 4,307,510 (issued August 5, 2009). However, this conventional device has the following problems. First, in the case where the polarizing film is bonded to the substrate, in order to prevent the dust 丄妁 〇 〇 〇 主动 主动 主动 主动 主动 主动 主动 主动 主动 主动 主动 主动 主动 : : : : : : : : 201 201 201 201 201 201 201 201 201 201 201 201 201 201 201 201 . Then, the clean room is subjected to air rectification. In order to suppress the production due to foreign matter, the amount of t minus the amount of light must be applied to the substrate in the vertical laminar flow rectification process. In this regard, the manufacturing system of Patent Document 1 has a structure in which a polarizing film is bonded to the substrate from the upper surface and the lower surface. However, in the case of performing the bonding on the polarizing film, there is a disadvantage that the rectifying environment flowing to the substrate is deteriorated because the polarizing film interferes with the gas flow (vertical laminar flow). As an example of bonding from the surface of the polarizing film, Figs. 14(a) and 14(b) show the airflow velocity vector in the above-described manufacturing system. In Fig. 14, there is a region in which an area A is provided with a region where a winding portion for a polarizing film is wound out; a region B is mainly a region through which a polarizing film passes; and a region c is provided with a polarizing film. The wound portion for the peeling film to be removed.

Also, clean air is supplied from a HEPA (High Efficiency Particulate Air) filter. Further, in Fig. 14(a), the airflow of the grille 41' through which the clean air is passed is moved in the vertical direction via the grille 41. On the other hand, in Fig. 14(b), since the grille 41 is not provided, the airflow moves along the floor after contacting the bottom of the lowermost portion of Fig. 14(b). In Fig. 14 (a) and (b), the 2F (2nd floor) portion is provided with the area a to the c area, so that the polarizing film interferes with the clean air from the HEPA filter 40. Therefore, it is difficult to generate a gas flow in a direction perpendicular to the substrate passing through the 2F portion. In this regard, a state in which the airflow vector in the horizontal direction is large (the density of the vector is dense) is formed. In other words, the state in which the rectification environment deteriorates. The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a bonding apparatus for a polarizing film which does not interfere with a corrected version of the correction period after the division of 5 1354150: 2011/3/Π, and a liquid crystal display device having the same Manufacturing system. In order to solve the problem, the bonding apparatus of the polarizing film of the present invention includes: the first substrate transporting mechanism is configured to transport the rectangular substrate in a state in which the rectangular substrate is transported in the long side or the short side; In the joint portion, the polarizing film is bonded to the lower surface of the substrate in the first substrate transfer mechanism; and the reversing mechanism is

In the J system, the substrate transported by the first substrate transport mechanism is reversed and provided in the second substrate transport mechanism, and the second substrate transport mechanism transports the substrate in the short-side or long-edge transport direction. And the second bonding adjacent layer bonds the polarizing film to the substrate in the second substrate transfer mechanism, and the first substrate transfer mechanism and the second substrate transfer mechanism are provided in the same direction. The mechanism has: a suction portion that sucks the

By using the long side or the short side of the substrate as the bottom side, the base is rotated to the first rotation of the first angle, and the substrate is reversed from the second rotation of the U second instrument; and the substrate is rotated. The substrate inverting portion returns the substrate surface in the substrate transfer mechanism by the first rotation, and the substrate rotation (four) axis is the towel row 4 9G. turn around. : = reverse = bonding portion to bond the polarizing film to the substrate to suck the substrate (==: substrate inversion portion: (1) the substrate is rotated by 90 with the suction portion substrate rotating portion. (4) Inverted part comes in (row) 1354150 After splitting, the correction correction date is corrected: 2011/3/11 The second rotation of the substrate, whereby the substrate is reversed, and the long side and the short side relative to the conveying direction can be simultaneously changed. Then The polarizing film can be bonded to the lower surface of the substrate by the second bonding portion. That is, the polarizing film can be bonded to the both surfaces of the substrate, so that the rectifying environment is not hindered. In the case of four simple operations, the tact time is short. Therefore, it is possible to achieve a short tact time. Further, the first substrate transfer mechanism and the second substrate transfer mechanism are disposed in the same direction. Therefore, the bonding apparatus of the present invention is easy to install and has an excellent area ratio. The bonding apparatus of the polarizing film of the present invention is as described above, and the first substrate moving mechanism and the first 2 the substrate transfer mechanism is disposed in the same direction, and The rotating mechanism has a absorbing portion for absorbing the substrate, and the substrate inverting portion is a long side or a short side of the two substrates as a bottom edge, and the substrate is rotated to the first (corner first turn and the substrate) The second rotation from the third angle of reversal

The substrate is reversed, and the substrate is rotated, and the substrate is rotated to the substrate. The substrate rotated by the first rotation is rotated by the substrate on the surface of the substrate in the i-th substrate feeding mechanism. The axis is centered and enters 90 degrees. Therefore, the substrate is reversed by the inversion mechanism, and the long side and the short side with respect to the transport direction can be changed. Thereby, the polarizing film is bonded to the both surfaces of the substrate from the lower surface, so that the rectification environment is not hindered. "Because the action of the anti-institution is 4 simple actions, the beat time is shorter. Therefore, it is possible to have a shorter tact time. Further, the second substrate transfer mechanism and the second substrate transfer mechanism are oriented in the same direction (four). That is, it does not have a complicated structure such as an L' shape. Therefore, the bonding apparatus of the present invention has the effect of setting the correction date of the active correction correction version after the non-segmentation: 2011/3/11 is often simple and the area efficiency is excellent. Other objects, features, and advantages of the present invention will become apparent from the description. Further, the advantages of the present invention will become apparent from the following description of the appended drawings. [Embodiment] [Embodiment 1] An embodiment of the present invention will be described with reference to Figs. 1 to 11 , but the present invention is not limited thereto. First, the structure of a manufacturing system (manufacturing system of a liquid crystal display device) according to the present invention will be described below. The manufacturing system includes the laminating device of the present invention. Figure 1 is a cross-sectional view showing the manufacturing system. As shown in Fig. 1, the manufacturing system 100 has a two-layer structure, the 1F (1st floor) portion is a film conveying mechanism 50, and the 2F (2nd floor) portion is a bonding device 60 including a substrate conveying mechanism. <Film transfer mechanism>

First, the film transfer mechanism 50 will be described. The film transport mechanism 50 can function to wind up the polarizing film (polarizing plate) and transport it to the rolls 6, 6a, 16, and 16a, and wind the unnecessary peeling film. On the other hand, the bonding apparatus 60 can function to bond the polarizing film wound by the film conveying mechanism 50 to the substrate (liquid crystal panel) 5. The film transport mechanism 50 includes a first film transport mechanism 51 and a second membrane transport mechanism 52. The first film transporting mechanism 51 is for transporting the polarizing film to the rolls 6, 6a which first bond the polarizing film to the lower surface of the substrate 5. Further, the substrate 5 has a rectangular shape. On the other hand, the second film transport mechanism 52 is configured to divide the polarizing film 1354150 and actively correct the corrected plate correction date: 2011/3/11 to the lower surface of the substrate 5 after the reverse rotation. The first film transport mechanism 51 includes a first take-up portion 1 , a second take-up portion 1a, a first winding portion 2, a second winding portion 2a, a half cutter 3, and a knife edge 4 And the defective film winding drums 7 and 7a. The raw material of the polarizing medium is provided in the first roll-out portion 1 so that the polarizing film can be wound up. As the polarizing film, a conventional polarizing film can be used. And 髀

In the case of the above, a film obtained by dyeing a polyvinyl alcohol film with iodine or the like and extending it along the direction of the AA can be used. The thickness of the polarizing film is not particularly limited, but it is preferable to use a polarizing film of 5 μΓη or more and 400 or less. In the raw material of the polarizing film, the island + machine direction (MD direction) is located in the direction of the absorption axis. The polarization _ is protected by peeling _ and being adhered (4). As the release film (also referred to as a protective film or a separation film), a polyester film, a poly-ply-ethylene vinegar (polyethylene acetonide, etc.) may be used. Although the thickness of the peeling shaft is not particularly mosquito, It is preferable to use a release film of 5 or more and 100 μm or less.

The manufacturing system 100 has two L-mountings and one solid-rolling portion, and has two winding portions corresponding to the winding-out portion. Therefore, when the amount of raw material remaining in the first roll of Qiu-out #1 is too small, the first The raw material of the first roll-out part 1 is connected to the raw material of the I-top street prepared by the roll-out part la. As a result, the bonding of the polarizing film does not stop, and the work can be continued. According to the structure, the production efficiency can be improved. Further, the winding portion and the winding portion may each have a plurality of, and may have three or more. In the first drawing, the first unwinding portion i and the second unwinding portion are structures that can be interchanged by the turn 2. When the position is interchanged, the second roll-out portion U of the 帛i roll-out portion moves around the circular orbit, and automatically divides the i-th roll-out portion k 9 1354150 and then actively corrects the revised version of the correction period 0: 2011/3/11 After the polarizing film is cut, it is automatically connected to the polarizing film of the second winding portion ia. The first roll-out part 11 and the second roll-out part ila are also the same. Further, the first winding portion 2, the second winding portion 2a, the first winding portion 2, and the second winding portion 12a are also configured to be rotatable by a turret. According to this configuration constituted by the turret, there is an advantage that the winding portion or the winding portion can be easily interchanged, and the films can be easily connected to each other. Moreover, as a modification of the winding portion, the structure shown in Fig. 2 can be cited. The first unwinding portion lb and the second unwinding portion lc of Fig. 2 are structures that are horizontally movable with respect to the winding core Id direction of the polarizing film. In other words, the i-b and the second winding portion lc are configured to be movable in the width direction of the polarizing film. Specifically, as shown in the right part of Fig. 2, the structure can be moved along at least one of the two directions of the winding core ld (in the direction of the incoming paper (indicating in the middle) and in the direction of the outgoing paper (in At least one of the marks having a mark in the middle) is moved according to the present structure. In the case of exchanging the polarizing film roll, the first roll-out portion lb or the second roll-out can be horizontally moved with respect to the direction of the core Id. Part ic and set a new polarizing film roller. Therefore, the first winding portion lb and the second winding portion lc are not turned upward; As shown in Figure 2, in the first! The upper portion of the winding portion lb and the second winding portion ic has the bonding device 60. However, according to the configuration, since the second winding portion ib and the ==C#_ld direction are horizontally moved, it is not necessary to let the volumes The space that moves upwards. Therefore, the space between the upper (C_eyor) drum 15 and the unwinding portion can be made to reach a space. As a result, a miniaturized bonding device can be provided, and even more, it can be corrected after the division of 1354150. The correction date is revised: 2011/3/11 A miniaturized manufacturing system is provided. The invention of the present application differs greatly from the conventional manufacturing system having a turret in that the aforementioned advantages of miniaturization are made. A manufacturing system having a turret is disclosed in, for example, Japanese Laid-Open Patent Publication No. Hei 8-208083.

When the residual amount of the roller of the polarizing film provided in the first winding unit 1b is too small, the operator connects the polarizing film of the second winding unit 1c. At this time, after the transfer speed of the polarizing film is set to 〇m/min, the operator cuts off the polarizing film on the side of the first winding portion lb. Next, the polarizing film is taken up from the second winding portion lc, and after the end portions are cut, the polarizing film is connected to each other by, for example, a single-sided adhesive tape.

Further, the first winding portion 2, the second winding portion 2a, the j-th winding portion 12, and the second winding portion 12a' in the first drawing are the same as the winding-out portion in the second drawing, and are also The structure in which the core direction of the release film moves horizontally. By having the above-described structure of the winding portion, the space between the transport roller 15 and the winding portion can be made more space-saving, and a more compact bonding device can be provided, and a more compact manufacturing system can be provided. . The half-cutting device (cutting portion) 3 cuts the polarizing film (the film laminate composed of the polarizing film, the adhesive layer, and the release film) protected by the release film to "half cut" to polarize the film and adhere thereto. The agent layer is cut. As the half-cutting device 3, a conventional component can be used. Specifically, a blade, a laser cutter, etc. are mentioned. After the polarizing film and the adhesive layer are cut by the half cutter 3, the peeling film is removed from the polarizing film by the blade edge (removing portion) 4. An adhesive layer is applied between the polarizing film and the release film, and after the release medium is removed, the adhesive layer remains on the polarizing film side. There is no adhesive layer of 11 as the adhesive layer. The thickness of the adhesive is also not particularly limited, ~40μιη. On the other hand, the second film transport mechanism 52 has the same configuration as that of the 51st, and has the first take-up portion 11 and the second take-up portion 2: 1 winding portion 12, second winding portion 12a, and half cut The wearer 13, the knife: the film winding drums 17 and 17a. Regarding the assignment of the same name = Λ shows that it has the same function as the component in the first film transport mechanism. The manufacturing system of the preferred embodiment has a cleaning unit. Washing 71 will wash the substrate 5 before attaching the polarizing film to the underside of the substrate 5 by (4) light (10). "Material Washing" 71 allows (4) to spray the washing nozzle, the brush, etc., to construct the washing material. By washing the substrate 5 with the cleaning portion 71 for a long time before the bonding, the substrate 5 can be paid. The bonding is performed in a small number of states. Next, the third embodiment is used to describe the blade edge 4. The third drawing shows a cross-sectional view of the peripheral portion of the rolls 6, 6a in the manufacturing system 100. The third figure shows the substrate. (5) The conveyance is carried out from the left side, and the polarizing film core having the dot-receiving layer (not shown in the figure) is conveyed from the lower left side. The polarizing film 10 has a release film 10b. The polarizing film 10a and the adhesive layer can be cut by the half-cutting device 3, but the peeling film 1b is not cut. The blade edge 4 is provided on the side of the peeling film 10b. The prismatic member for peeling off the film 1〇b, and the peeling film 10b having a lower adhesive force with the polarizing film 10a are peeled off along the blade edge 4. ' 12 1354150 . Active correction correction after division Correction date: 2011 /3/11 Then, the release film 10b is wound up to the first winding portion 2 of Fig. 1. In addition, instead of the blade edge, it may be used to adhere The structure of the peeling film is wound by the roller. At this time, the winding efficiency of the peeling film can be improved by the adhesive roller at the two positions similarly to the winding portion. Next, the bonding device 60 will be described. The substrate 5 is transferred, and the polarizing film conveyed by the film transport mechanism is bonded to the substrate. Although not shown in the drawing, the bonding device 60 supplies clean air to the upper surface of the substrate 5. By rectifying the downflow, the substrate 5 can be conveyed and bonded in a stable state. Bonding device> The bonding device 60 is disposed above the film transport mechanism 50. Thereby, the manufacturing system 100 can be achieved. In addition, the substrate transfer mechanism including the transport roller is provided in the bonding apparatus 60, and the substrate 5 is transported in the transport direction (the first substrate transport device 61 will be described later in the first drawing). The second substrate transfer device 62 corresponds to the substrate transfer mechanism.

The manufacturing system 100 transports the substrate 5 from the left side, and then transports it from the upper portion of the first film transport mechanism 51 to the upper portion of the second film transport mechanism 52 to the right in the figure. Each of the film conveying mechanism 50 and the bonding skirt 6 has a roll 6 and 6a (first bonding portion) as a bonding portion, and rolls 16 and 16a (second bonding portion). The rolls 6, 6a and 16, 16a are used to bond the polarizing film 10a from which the film 11b has been removed to the assembly under the substrate 5. In addition, in order to bond the polarizing film 10a to the both surfaces of the substrate 5 from below, the polarizing film 10a is bonded to one side of the surface by the rolls 6, 6a, and the substrate 5 is reversed by the reversing mechanism 65. . The reverse mechanism 65 will be described in detail later. 13 ϋΜ150 points after the oblique correction of the active correction revision date: 2011/3/11 moving the Liao to the rolling *6, 6a polarizing film l〇a will be sandwiched with an adhesive layer and σ attached to the underside of the substrate 5. As the rolls 6, 6a, a conventional structure such as a press roll or a press roll can be used. Further, the rolls 6 and 6a are adjusted at the time of bonding and/or diametrical. The structure of the rolling light 16, 16a is also the same. In addition, although not shown in the drawings, as a preferred structure of the manufacturing system, a defect mark (marked) between the f 1 roll-out portion 1 and the half-cut device should be detected to detect a defect. The structure of the polarizing film. 4 r 11 This defect is detected when the polarizing film material is made and is displayed, or it can be closer to the stand by the defect detection. The defect mark provided on the side of the 11 or the second roll-out portion 11a is granted to the field = on the polarizing film. The defect indication granting unit is composed of a camera, an image processing apparatus, and a defect indicator forming unit. First, by using the camera, the shooting of the field-biasing field can be detected to have defects. Specific examples of the defect include foreign matter such as dust, fisheye, and the like. When a defect is detected, a defect mark is formed at the polarizing film by the defect mark forming portion. As the defect mark, a mark such as ink can be used. Further, the bonding avoiding portion not shown in the figure discriminates the flag by the camera, and transmits a stop signal to the bonding device 60 to stop the conveyance of the substrate 5. Then, the polarizing film in which the defect is detected is not bonded by the rolls 6, 6a, but is wound up to the defect film winding drum (recycling portion) 7, 7a. Thereby, <avoiding that the substrate 5 and the polarizing film having defects are bonded to each other. If the series of structures are employed, it is possible to prevent the defective polarizing film from adhering to the substrate 5 and to improve the yield, so that the structure is preferable. As a defect detection 1354150 and a close-fitting A-segment, the active correction correction revision period: 2〇ll/3/ll can use a conventional detection sensor. After the slain state, the k reversing mechanism 65 is used to reverse the substrate 5. $ a 4- <- 5 is transferred to the rolls 16, 16a. Next, the polarizing film is attached to the underside. As a result, the polarizing film is bonded to both surfaces of the substrate 5, and the two sides of the substrate 5 are bonded to each other with two offsets, ', and the shape f, which have different absorption axis angles. According to the need, it is necessary to detect and investigate the two sides of the substrate 5 to cause a fitting deviation. This detection can usually be carried out by means of a detector having a camera. (4) Manufacturing system_中 When the polarizing film is bonded to the substrate 5, the structure is bonded from the lower surface of the substrate 5, so that the rectifying environment of the substrate $ is not hindered. Therefore, it is possible to prevent the foreign matter from being mixed to the bonding surface of the substrate 5, and the bonding can be performed more accurately.

Figures 4(4) and 4(b) show the velocity vector of the airflow in the pasted manufacturing system, which is the same as the present invention. In the fourth drawing (&), (b), the area A is a region in which the winding portion is provided, the region B is mainly a region through which the polarizing film passes, and the region C is a region in which the winding portion or the like is provided. Further, clean air is supplied from the HEpA filter 40. Further, in Fig. 4(a), since a grating 41 through which clean air can pass is provided, the airflow moves in the vertical direction via the grill 41. On the other hand, in Fig. 4(b), since the grid 41 is not provided, the airflow moves along the floor after coming into contact with the floor. Since the manufacturing system shown in Figs. 4(a) and 4(b) is of the lower-mount type, as shown in Figs. 14(a) and (b), the airflow from the HEPA filter 40 is not hindered by the polarizing film. Therefore, the direction of the airflow vector is almost always toward the substrate, and a better rectifying environment can be realized in the clean room. Figure 4 (a) is provided with a grid 15 1354150. After splitting, the correction correction date is corrected: 2011/3/11 41, and although not shown in Figure 4 (b), both figures show the same. Good state. Further, in Figs. 4 and 14, the substrate transfer mechanism has a horizontal structure, but is not provided in a series of structures. Therefore, the substrate transfer mechanisms are configured to allow airflow therethrough. The substrate can be transferred between the substrate transfer mechanisms by holding the substrate by a reversing mechanism to be described later. In the manufacturing system, first, the substrate 5 is transported with the long side facing forward (the long side is perpendicular to the transport direction), and then the short side is forward (the short side is perpendicular to the transport direction). The structure is carried out in the state of being transported. [Structure of Film Connection Portion] Further modifications of the bonding apparatus according to the present invention will be further described. Fig. 5 is a cross-sectional view showing a modification of the bonding apparatus 60 of the present invention. In the first film transporting mechanism 51 of the fifth embodiment, the first winding portion lb and the second winding portion lc are the same as those of the second embodiment, and are configured to be horizontally movable with respect to the winding core Id direction of the polarizing film. The first film transporting mechanism 51 has a film connecting portion (first film connecting portion) 83 and a film connecting portion (second film connecting portion) 93, and the polarizing films 10 and 20 can be connected by these. Fig. 6 is a perspective view showing the film connecting portion 83 and the cutter 87. As shown in Fig. 6, the film connecting portion 83 has suction portions 84 and 84a and a cutting and bonding portion 85. The absorbing portions 84 and 84a are components for affixing and fixing the polarizing film. The absorbing portions 84, 84a have a flat plate shape and have a plurality of absorbing mechanisms 89 on the surface thereof. The absorbing mechanism 89 is not particularly limited as long as it can absorb the polarizing film, and a structure in which the polarizing film is sucked by pumping can be used. 1354150 Active correction corrected version after splitting date: 20I1/3/u The cutting and fitting portion 85 can be rotated and has a plurality of faces. Specifically, the cut and bonded portion 85 has a polygonal shape. Also, it can be set in a turn. Further, in the preferred embodiment, 'they can be moved in the vertical direction with respect to the polarizing film 1G. Since it is movable in the vertical direction with respect to the polarizing film 1G, the #cutting bonding portion is performed: when the α is rotated, the cutting and bonding portion 85 moves in the direction perpendicular to the polarizing film and away from the polarizing film 1G, and then It can be rotated. Then, the knife-cut fitting portion 85 is moved in the direction perpendicular to the polarizing film 1 且 in the direction perpendicular to the polarizing film 1G so as to be in the initial position. Thereby, it is possible to surely avoid the contact between the corner portion of the bonding portion 85 (the portion including the narrow surface adjacent to the bonding surface (10) and the bonding surface) to the polarizing film (7), which is a preferable structure. Further, the 'cutting and affixing portion 85 has a polygonal shape, and as shown in Fig. 7, has a cutting support surface 85 & a bonding surface 8 讣 and 85 c at three sides thereof, but may have more i-cuts Floor and/or fitting surface. For example, the surface having the cut-off floor surface and having a bonding surface on three or four sides is provided, and the cutting surface is provided on both sides, and is provided on three or four sides. The structure of the mating surface. Further, as shown in Fig. 6, the cutting and bonding portion 85 is chamfered between the bonding surfaces and between the cutting support surface and the bonding surface, so as to avoid cutting the stickers as long as the corner portions can be formed. The joint portion 85 and the polarizing film are preferably in a structure in contact with each other. The size of the cutting and bonding portion 85 is appropriately determined depending on the width of the polarizing film 10, and is not particularly limited. However, it may be, for example, a length of 200 mm or more and 2000 mm or less, and a width of 10 mm or more and 3 mm or less. Fig. 7 is a perspective view showing the cutting and bonding portion 85. Fig. 7 shows the state of the correction correction after the division of 1354150. Correction date: 2011/3/11 The state in which the cutting and bonding portion 85 of Fig. 6 is rotated clockwise by 1/3 turn. As shown in Fig. 7, the cutting and bonding portion 85 has a cutting support surface 85a that supports the polarizing film 10 along the width direction of the polarizing film 10. Further, the bonding surfaces 85b and 85c have a absorbing mechanism 89 having a absorbing material, and the connecting member connects the polarizing films 10 and 20 to cover the cutting line of the polarizing film 10 after the cutting. It is also possible to have a structure in which two or more bonding surfaces are provided. The cutting support surface 85a is formed with a groove-shaped opening 86, and has a structure in which the blade portion of the cutter 87 having the cutting and bonding portion 85 shown in Fig. 6 is passed. By forming the opening 86, the cutter 87 can be reliably passed in the width direction of the polarizing film 10, and the polarizing films 10 and 20 can be more accurately connected. The cutter 87 can be a conventional cutter, and since the rounded blade can cut the polarizing film 10 lightly, it is preferable. Further, the cutter 87 is supported by the pedestal portion 88 which is driven in the width direction of the polarizing film 10. The bonding surfaces 85b and 85c have the same structure, and have a plurality of absorbing mechanisms 89 similarly to the absorbing portions 84 and 84a. Further, the bonding surfaces 85b and 85c are provided with a single-sided adhesive tape (connecting material) 85d, and the suction mechanism 89 holds the non-adhesive surface of the single-sided adhesive tape 85d so that the single-sided adhesive tape 85d is adhered. The face and the bonding faces 85b, 85c are opposite to each other. The single-sided adhesive tape 85d can be used as long as the polarizing film can be bonded to each other, and a conventional single-sided adhesive tape can be used. As the film material of the single-sided adhesive tape 85d, for example, a polyethylene terephthalate film (PET film), cellulose, and paper (washi), imprinted, non-woven fabric, polytetrafluoroethylene, polyethylene, Polyvinylidene chloride, polycarbonate, polyurethane, ABS resin, polyester, polystyrene, polyethylene, polypropylene, polyacetal resin, polylactic acid, polyacrylic acid 1354150. After the split, the active correction correction version is revised: 2011/3/11 Amine, polyamine, etc. Moreover, examples of the adhesive for the adhesive layer include acrylic, epoxy resin, polyurethane, synthetic rubber, EVA, sulfhydryl, vinyl chloride, chloroprene rubber, and cyano. An adhesive such as an acrylate-based, isocyanate-based, polyvinyl alcohol-based or trimeric guanamine resin. The film connecting portion 83 is disposed opposite to the polarizing film 10. Therefore, in Fig. 5, since the polarizing film 10 is vertically disposed, the film connecting portion 83 is also vertically disposed. On the other hand, when the polarizing film 1 is disposed, for example, in an oblique direction (or a horizontal direction), the film connecting portion 83 may be configured to be disposed in an oblique direction φ (or a horizontal direction or the like) so that the film connecting portion 83 is provided. It has a structure opposite to the polarizing film 10.

The film connecting portion 93 and the film connecting portion 83 have the same structure. The film connecting portions 83 and 93 are provided as shown in Fig. 5 so that the sucking mechanisms of the sucker portions provided in the film connecting portions 83 and 93 are opposed to each other. Further, the film connecting portions 83 and 93 are interposed between the polarizing film 1〇 and the polarizing film 2〇. Further, the manufacturing system 100 having the film connecting portions 83 and 93 is a preferred embodiment of the present embodiment, and may be in a form without the film connecting portions 83 and 93. [Operation of the film joint portion] The operation of the manufacturing system in the form of the 页 关 关. In addition, this description of the operation also serves as an explanation of the method of manufacturing the optical display device. First, as shown in Fig. 1, the process of the polarizing film 1 is performed from the i-th roll portion. However, as shown in FIG. 3, only the polarizing film 1Ga is half-euted by a blade not shown in the figure, and is peeled off by a peeling film (peeling process). . Further, the polarizing film IGa after the (10) film (10) is pressed by the substrate to be bonded to the substrate 5 19

I^D41DU After the split, the active correction correction version a period: 2011/3/u 仃 fit (fit process). In addition, the peeled release film i〇b will be rolled up. It is collected in a winding portion not shown in the drawing. The optical display can be obtained by bonding the substrate S and the polarizing film 10a to each other by the series of processes. In the series of processes, the polarizing film 1G is unwound, and the residual amount of the roller of the polarizing film 10 which is held by the first coil is gradually reduced. I will tell you about the connection process of connecting polarizing films to each other. In the connection process, the polarizing film 2 of the e-outlet 1 (u, lb) is wound out of the portion la (lla, lc). Cut off. Then ‘roll out. Among the polarizing film 10 and the second winding portion la(1) of P1 (11), the line side of the first winding portion 1 (11, lb) or the line side of the second winding portion la (Uavlc) The polarizing film 2〇 is different from the polarizing film buckle on the side of the winding portion of the second winding portion la (lla, le) or the polarizing film M1M on the side of the winding portion of the first winding portion 1 (1b) The so-called "line side" is connected, in other words, the direction in which the polarizing film is wound out. The joining process is a method in which the operation is performed by the operation M, and the method is performed by the film connecting portions 83 and 93. First, Specifically, the method of the operator (1) is performed by the operator. The case where the polarizing film is connected to each other by the operator is as follows: after the transfer speed of the light film 10 is set to 0 m/min (will After the polarizing enthalpy is stopped, the operator cuts the polarizing film 1 。. Next, the polarizing film 20 is taken up from the ith winding portion 11 and the end portion thereof is cut, for example, using the above-mentioned single-faced tape 85d. In this way, in the manufacturing system of the present invention, there is a second roll-out part, 20 1354150, and an active red-red version correction date: When the polarizing film roll is replaced with a new one, the polarizing film 10 and 20 can be used to immediately connect the film, and the polarizing film 20 can be quickly wound out. Therefore, it is known that the winding portion is provided only at one position. In the manufacturing system, since the raw material roll can be exchanged for the empty take-up portion during operation, the time required for the exchange operation can be reduced. As a result, the manufacturing time of the optical display device can be shortened. In the manufacturing system, the polarizing film is folded. After the completion of the connection of 20, the roller of the polarizing film 10 of the summer winding portion 1 can be replaced with a new one during the period in which the polarizing film 20 is unwound. The polarizing film 2 is reduced. Similarly, the polarizing film 20 and the polarizing film 10 are connected to each other. - The cholesteric muscle %% is used for the film connecting portions 83 and 93. Fig. 8 shows the connection by the manufacturing system including the film connecting portion. Process chart of the process. When the residual amount of the polarizing film 1 is reduced, the polarizing film 10 is set to a transport speed of the polarizing film 1 as shown in Fig. 8 (4), and then the absorbing portion 84 is 84& and cutting and fitting

85 (the film connecting portion 83) moves in the vertical direction with respect to the polarizing film 1A. Next, the polarizing film 1 is sucked by the suction mechanism 89 of the absorbing portions 84, 84a to be fixed (suction process). , when the 'cutting and fitting part 85' cut off the branch floor, I will contact the partial:: the door' as shown in the eighth _, let the cut not shown in the figure 3 = 1 move and the polarizing film 10 cut (cut process). The cutting is performed such that the cutting and squeezing portion 85 moves in the direction perpendicular to the polarizing film 且 in the vertical direction and away from the phase (the right side in the drawing), and rotates counterclockwise by 1/3 turn, and is opposite to the thinning_vertical direction. Close to the direction of the 敎 domain (left side of the figure) 叙 * * After the cut, the active correction correction version of the correction date: 2011/3/11 The face of the 85b army ^ make it as shown in Figure 8 (4), you can fit the tape 8sd (85<1 fits to cover one-sided adhesion). The cutting line of the polarizing film 1 前 of the former fan (b caused by the bonding process refers to the side of the polarizing film 1 黏 黏 : : : : : ' ' ' 。 。 。 。 。 。 。 。 。 。 。 。 。 In the bonding process, it may be provided so as to cover the cutting line, that is, a portion that does not exist even if the polarizing film 1G does not exceed the cutting line. For the polarizing film 20, and FIG. 8 (8) to (4) Similarly, the single-sided adhesive tape 95d is adhered to the (four) support surface 95a of the polarizing film 2A. The same components as those of the foregoing components are given the same name, and the description thereof is omitted. First, the polarizing film 20 is removed from the first winding portion. 11 is rolled out, and the end portion of the polarizing film 20 is cut off in the same manner as in Fig. 8 (4), and the polarizing film 20 is moved by the opening σ 96 formed by cutting the branch floor surface 95a. After the cutting, the cutting and bonding portion 95 is moved in the direction perpendicular to the polarizing film 20 in the vertical direction and away from the polarizing film 20 (the left side in the drawing), and is rotated clockwise by 1/3 turn with respect to the polarizing film. 2G moves in the direction perpendicular to the polarizing film 20 (the right side in the drawing). Thus, as shown in Fig. 8b, one side can be attached. The adhesive tape 95d covers the cutting line of the polarizing film 1A of the single-sided adhesive tape 85d (not shown) facing the bonding surface 95b. Next, as shown in Fig. 8(f), the absorbing portions 84 and 84a and the cutting and bonding portion 85 (the film connecting device 3) are brought close to the absorbing portions 94 and 9 and the splicing and bonding portion 95 (film). The connecting portion 93) joins the cross sections of the polarizing film 10 and the polarizing film 2 to each other (close to the process). Thereby, the part of the single-sided adhesive tapes 85d and 95d covering the cutting lines of the polarizing film 1〇 and 2〇 exceeds the part of the cutting line (not 22 ^ 4150 after the eight-part split, the active correction correction date is revised: 2011/3 /11 5 to a portion of the polarizing film 10, 20), the polarizing films 1 〇 and 2 〇 are connected to each other by bonding to the polarizing 祺 20, 1 另一 on the other side. (Fig. 8) The film connecting portion 83 is brought close to the film connecting portion 93. However, the film connecting portion 93 may be approached to the film connecting portion 83, and the film connecting portions 83 and 93 may be brought close to each other. After the polarizing films 10 and 20 are connected, as shown in FIG. 8 , the cutting and bonding portions 85 and 95 are moved in the vertical direction and away from each other with respect to the polarizing films 1 and 2 . The cut and pasted portion 85 is rotated clockwise by 1/3 turn, and the cut and pasted portion 95 is rotated by 1/3 turn counterclockwise. Then, the damming portions 85, 95 are each moved in the vertical direction and in the approaching direction with respect to the polarizing films 1A, 2''. Finally, the absorbing portions 84 and 84a and the cutting and bonding portion 85 (membrane away from the center) are returned to the first set, and the end-series process is completed. The other side 85c, 95e is a pre-adsorbed single-sided adhesive tape 8 brother,

The wave is set to 'the second roll-out portion 1C is provided with a new polarizing film 10, and the process of the eighth (~) to (4) process is performed for the polarizing film 2G, and the eighth to the (e) processes are performed for the image bias = ,, And as described above, through the 8th: (^ process can be used to connect the polarizing film 2〇, 1〇 to each other. In addition, the knot polarized light will be added to the 仃, and of course, the continuous age can be connected! In the case of the connection process of the connection portions 83 and 93, the connection process by the operator can be sucked in a shorter time and more accurately, and it is a better structure. In the manufacturing system, the connection system made by the operator is 23 135,415 〇 and the active correction correction version is revised. The time of the 2011/3/11 process takes about 10 minutes, but the membrane connection portion 83 is used. In the case of 93, it is possible to complete in one minute. In this manufacturing system, only the first winding portion 1 is used, the first winding portion 11 is not used, and the film connecting portions 83 and 93 are not used. The operator needs to exchange the polarizing film 10 after exchanging the first roll-out portion 1 into a new polarizing film, so the connection process takes 30 minutes. Therefore, it is apparent that the manufacturing system of the present embodiment is advantageous. <Reverse mechanism> The reversing mechanism 65 is configured to change the substrate 5' of the short side or the long side in the transport direction to the long side or The state of the short edge transport direction (the state after the inversion). Fig. 9 (a) to (d) are perspective views showing the process of inverting the substrate 5 by the reversing mechanism. Fig. 9(a) shows The substrate 5 transported by the first substrate transport mechanism is sucked, and FIGS. 9(b) and 9(c) show the process of moving the substrate 5, and FIG. 9(d) shows the second. In the state in which the substrate is reversed, the substrate 5 is reversed. For the sake of convenience of illustration, the substrate transfer mechanism is omitted in the ninth drawing, and the image is escaped using the tenth image. As shown in Fig. 9(a) The reversing mechanism 65 has a absorbing portion 66, a substrate reversing portion 67, and a substrate turning portion 68. The absorbing portion 66 is a member for absorbing the surface of the substrate, thereby holding the surface of the substrate 5 at the absorbing portion 66. The absorbing portion 66 can use a conventional absorbing portion, for example, a absorbing portion can be used. The portion 66 is for reversing the substrate 5 with the substrate 5 ^ as the bottom side. In the ninth diagram, the substrate reverse phase 7 is a rotary axis structure, and the substrate reversal portion 67 is rotated to allow n and 24 After splitting, the corrected correction correction date is: 2011/3m and P 6k. However, the substrate inverting portion is not limited to the front structure. It is also possible to rotate the absorbing portion 66 by the driving portion. The substrate inverting portion 67 is divided into a first rotation and a second rotation to perform an inversion of the substrate 5. The inversion of the fifth is divided into a first rotation and a second rotation. The reverse rotation refers to turning the substrate 5 to the opposite. The side surface, in other words, the surface of the substrate 5 is set to be the inner surface. Fig. 9(a) shows the short edge transport direction of the substrate $. As in Fig. 9(b), the ith turn uses the long side of the substrate 5 as the base to rotate the substrate 5 (Fig. 9 (Fig. 9) a) - Figure 9 (b)). This first turning system rotates the substrate 5 to the first angle. The first angle refers to less than 18 inches. X. . From the viewpoint of balancing the substrate 5 rotated by the first rotation by the substrate turning portion 68 and simplifying the design of the reversing mechanism 65, X is 80. Above and 11〇. The following is preferred as 85. Above and 95. The following is better as '90. The best.

The substrate rotating portion 68 has a substrate inverting portion 67 for rotating the substrate 5 that has been rotated by the first rotation with respect to the substrate 5 in the first substrate transfer mechanism (not shown) (that is, the substrate shown in FIG. 9(a) The surface of 5) is rotated 9 turns around the rotation axis of the substrate turning portion 68. . Carry out 9〇. The direction of rotation at the time of turning is set to the inside of the long side or the short side which is perpendicular to the conveyance direction, and the long side or the short side which is located in the conveyance direction side. The substrate inverting portion 67 shown in Fig. 9(c) is a structure in which the base portion is rotatable. The substrate turning portion 68 is configured such that the substrate 5 can be rotated 90 about the rotation axis of the substrate turning portion 68 with respect to the surface of the substrate 5 in the first substrate transfer mechanism. The configuration is not limited to the configuration shown in the drawings. As the substrate 25 inversion part 67 and / 3⁄4 Mei Tuo, after splitting, the active correction correction version correction date: 2〇ιι/3/ιι arm case, can enter: fine; =, use the robot with the control part as the robot arm It can be used as a preferred structure. For example, if the substrate is rotated and the robot arm can be used as the substrate reversal portion, the structure is not particularly limited as in the case of the Qth actor. By rotating, the substrate 5 having the second or short side of the substrate inverting portion 67 as the bottom side two (four) shown by the second drawing is used, and the long side of the substrate 5 is used to Rotate again to reverse the state. The 9th soil 5 is reversed, and a state in which the short edge is conveyed is formed. In the second rotation l (d), the long side of the substrate 5 is used as the base. In the first rotation and according to the data, U: the length of the substrate 5; in the short side of the f and the short side, the long side is the bottom side, and the short side is the bottom side. . It can be entered in any state. g 1Q _ The same diagram shows the plane of the substrate 5 in the slewing process in Fig. 9. In the first drawing, M T ' is displayed with the first substrate transfer mechanisms 61 and H in addition to the reversing mechanism 65. * 2 substrate transfer mechanism 62. The first substrate transfer mechanism 61 and the second substrate material mechanism 62 are provided at the transport roller. The first substrate transfer mechanism 61 is provided in the same direction as the substrate transfer mechanism 62. That is, it does not have a complicated structure such as an L-shape. Therefore, the setting of the bonding apparatus 60 of the present invention is very simple and excellent in area efficiency. As described in Fig. 9, first, the surface of the substrate 5 is held by the absorbing portion 66, and the substrate inverting portion 67 is rotated 90 in the direction of the beam. (The fourth sub-rotation (4) (10). Then, the substrate 5 that has been rotated by the first rotation is divided and corrected with respect to the first 26 1354150, and the correction correction date is: 2011/3A1 The substrate 5 in the substrate transfer mechanism 61 (ie, The surface 'the surface of the substrate 5) of the first figure (a) is rotated 90 around the rotation axis of the substrate rotating portion 68. (Swing in the direction of the arrow in the first figure (b), the first figure —) - 1〇图(c)). Finally, the substrate 5 is reversed by the second rotation of the substrate inverting portion 67 (Fig. 10 (4) - Fig. 10 (d)). The absorbing portion 66 and the roller drum that are not shown in the drawing of the second substrate conveying mechanism 62 are not in contact with each other. After the holding of the substrate 5 is released by releasing the suction of the absorbing portion 66, the substrate 5 is transported by the second substrate transport mechanism 62. Next, the reversing mechanism 65 returns to the position of Fig. 10 (a), and inverts the other substrates 5 that are sequentially transported in the same operation. According to the above-described reversing mechanism 65, the suction unit 66 can be sucked, the first rotation, the second substrate transport mechanism 61 can be returned to the second substrate transport mechanism 62 by 90°, and the second rotation can be performed. The action can reverse the substrate 5 while changing the long side and the short side corresponding to the transport direction. This operation is completed = 'The polarizing film can be attached to the both sides of the substrate 5 from below. Further, since the operation is four simple operations, the takt time is short. Therefore, ΰρ香: n 2 can be achieved without hindering the rectifying environment and having a short tact time. The substrate 5 is temporarily stopped between the first rotation and the second rotation, and the substrate is temporarily stopped during the first rotation and the second rotation, that is, when the ground is rotated, each of them is included in the first 1 rotation and 2 = in other words, the front and rear of the substrate 5 are rotated by the substrate rotating portion 68, and the rotation of the substrate inverting portion 67 by the substrate inverting portion 67 is the first rotation and the second rotation. In Fig. 10, after the first substrate transfer mechanism 61 and the second substrate transfer machine 27 1354150 are divided, the correction correction date is corrected: the transport direction of the 2011/3A1 structure 62 is not provided on the straight line, but has an adjacent structure. This is because the substrate 5 is rotated by 90° by the substrate turning portion 68 as shown in FIG. 10(c). Therefore, the final substrate transfer direction of the substrate 5 as shown in FIG. 10(d) is performed by the first substrate transfer mechanism 61 and An offset occurs between the second substrate transfer mechanisms 62. Fig. 11 is a plan view showing a modification of the bonding apparatus 60 using the two reversing mechanisms 65. The change point of this modification is: (1) two reversing mechanisms 65; (2) the first substrate transfer mechanism 61 has a substrate mounting portion 61a; (3) the first substrate transfer mechanism 61 and the second substrate The conveying mechanism 62 is disposed on a straight line. Further, the first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 are provided in the same direction, and the same points are obtained. The end portion of the first substrate transport mechanism 62 on the side of the second substrate transport mechanism 62 has a substrate mounting portion 61a and a reversing mechanism 65 in both horizontal directions with respect to the transport direction of the first substrate transport mechanism 61 at the end portion. The reversing mechanism 65 is constructed as shown in Figs. 9 and 10. Further, the end portion has a transport mechanism for transporting the substrate 5 to the substrate mounting portion 61a. Specifically, for example, a transport roller can be mentioned. The substrate mounting portion 61a is located at the end of the conveyance of the substrate 5 before the first turning. According to this configuration, the substrates 5 transported to the first substrate transfer mechanism 61 are alternately transferred to the two substrate mounting portions 61a. Since the substrate mounting portion 61a and the reversing mechanism 65 are provided in two pairs, the substrate 5 conveyed to the substrate mounting portion 61a is rotated by the reversing mechanism 65 to form the first rotation, the 90 rotation, and the second rotation. Reverse state. In this modification, since the horizontal direction of both sides of the first substrate transfer mechanism 61 is 28, the revision date is actively corrected, and the corrected version correction date is 2011/3A1 m 仏, so the substrate 5 of the counter-action can be along the base i Transfer: Set the transport direction of H61. Therefore, the first earth sheet conveying mechanism 61 and the second substrate transport mechanism 62 can be disposed on a straight line. The time "t into St: there are 2 reversing mechanisms 65' to process 2 times per unit night. This way, more than 1 inversion can be reversed per unit time, so the tact time can be shortened. (2) Due to

The mechanism 61 and the second substrate transfer mechanism 62 are provided at all times, and a structure (four) device which is more excellent in area efficiency can be provided. In particular, the area efficiency is required in the case of dust-free, so the fitting device is excellent. &lt;Other attached structure&gt; Further, as a preferred embodiment, the manufacturing system 100 includes a control unit 70, a cleaning neighbor 71, a bonding deviation detecting and placing automatic foreign matter detecting device 73, and a selection and transportation. The bonding deviation detecting device 72, the bonded foreign matter automatic detecting device 73, and the selective conveying device 74 are used to detect the substrate 5 after bonding, that is, the liquid crystal display device.

Fig. 12 is a block diagram showing the connection of the components of the manufacturing system of the liquid crystal display device, and Fig. 13 is a flow chart showing the operation of the manufacturing system of the night crystal display device. Hereinafter, the operation of each of the components of the liquid crystal display device will be described. The control unit 70 is connected to the cleaning unit 71, the bonding deviation detecting device 72, the bonded foreign matter automatic detecting device 73, and the selective transport device 74' to control the transfer of the control unit to the components. The control unit 70 is mainly composed of a CPU (Central Processing Unit), and may have a memory as needed. 29 minutes after the active correction revision revision date: 2011/3/11 Liu 7/Clothing W system 1〇0 has the cleaning unit 71, in order to shorten the tact time of the washing station 'the first substrate transfer mechanism 61 It is preferable that the substrate 5 is transferred to the cleaning (four) in a manner of Μ. Usually, it is very effective to wash the cleaning part for a long time, and from the viewpoint of shortening the tact time. f g ^人, a bonding process for bonding the polarizing film to both sides of the substrate 5 is carried out. S2)' of the process is as described in the drawings to the nth. The tamper-evident deviation detecting means 72 is for detecting whether or not there is a deviation of the polarized light for the bonded substrate 5. The bonding deviation detecting device is composed of a camera and an image processing device, and the camera is provided at a bonding position of the substrate 5 to which the polarizing film is bonded by 纟(4)16, (10). By taking the image of the substrate 5 by the camera, the captured image information is processed, whereby it is possible to detect whether or not the substrate 5 has a bonding deviation (the bonding deviation detecting process, S3 of Fig. 13). Further, as the bonding deviation detecting device 72, a conventional bonding deviation detecting device can be used. The bonded foreign matter automatic detecting device 73 is for detecting whether or not foreign matter is present in the bonded substrate 5. Similarly to the bonding deviation detecting device 72, the bonding foreign matter automatic detecting device 73 is composed of a camera and an image processing device, and the second substrate transfer mechanism of the substrate 5 is bonded to the polarizing film by the rolls 16 and 16a. The camera is provided at the bonding device 60. The camera 5 is photographed by the camera, and the captured image information is processed, whereby the substrate 5 can be detected whether or not the foreign matter is bonded (the foreign matter detecting process is bonded, S4). Examples of the foreign matter include foreign matter such as dust, fisheye, and the like. Further, as the bonded foreign matter automatic detecting device 73, it is possible to use the conventional fitting deviation 30 1354150 to divide and then actively correct the modified version of the correction period: 2011/3/11 The detecting device ° The order of S3 and S4 can also be reversed, or Can be done at the same time. Also, the process of one of them may be omitted. The selection conveyance device 74 is configured to determine whether or not there is a difference in adhesion and foreign matter based on the detection results from the bonding deviation detecting device 72 and the bonded foreign matter automatic detecting device 73. The selection conveyance device 74 may be an output signal capable of receiving the detection results from the bonding deviation detecting device 72 and the bonded foreign matter automatic detecting device 73 to select a good or defective product from the bonded substrate 5. Therefore, the conventional pick-and-place transport system can be used. A preferred embodiment of the manufacturing system of the liquid crystal display device is a structure capable of detecting both a bonding deviation and a foreign matter, and when it is determined that a bonding deviation or a foreign matter is detected (YES), the bonding is performed. The good substrate 5 is selected as a defective product (S7). On the other hand, when it is judged that none of the bonding deviation and the foreign matter M(NO) is detected, the bonded substrate 5 is selected as a good product (S6) 〇

According to the manufacturing system of the liquid crystal display device having the selection transfer device 74, the selection of good products and defective products can be quickly performed, so that the tact time can be shortened. In the case where only the bonding deviation detecting device 72 or the foreign matter automatic detecting device 73 is attached, the selection conveying device 74 may be configured to determine whether or not the bonding deviation and the foreign matter are present. In addition, the specific embodiments described in the detailed description of the invention are only used to disclose the technical contents of the present invention, and should not be construed as being limited to the specific examples, and the spirit of the present invention will be described later. The documented patent application can be implemented in various ways. 31 1354150 After the split, the active correction revision date is revised: 2011/3/11 In addition, the present invention also includes the following aspects. Further, in the bonding apparatus of the polarizing film of the present invention, the first substrate transfer mechanism and the second substrate transfer mechanism are disposed on a straight line, and the second substrate transfer mechanism side end of the first substrate transfer mechanism Two pairs of substrate mounting portions and the reversing mechanism are provided in each of two horizontal directions along the conveying direction of the first substrate conveying mechanism at the end portion, and the end portion has the end portion A transfer mechanism that transports the substrate to the substrate mounting portion, and the reversing mechanism is provided in the second substrate transfer mechanism by reversing the substrate that is transferred to the substrate mounting portion. According to this configuration, the substrate can be double-processed per unit time by having two inversion mechanisms'. Thereby, more substrates 5 can be reversed per unit time, so the tact time can be shortened. In addition, the first substrate transfer mechanism and the second substrate transfer mechanism are provided on a straight line to provide a bonding device having a structure having a more excellent area efficiency. Further, in the bonding apparatus for a polarizing film of the present invention, the first film transporting mechanism and the second film transporting mechanism that transport the polarizing film are provided, and the first film transporting mechanism has a protective film that is protected by the peeling film. a plurality of winding portions that are wound by the polarizing film, a cutting portion that cuts the polarizing film, a removing portion that removes the release film from the polarizing film, and a plurality of winding portions that wind the removed release film; In the second film transporting mechanism, the plurality of winding portions that wind up the polarizing film protected by the peeling film, the cutting portion that cuts the polarizing film, and the removing portion of the secret film from the polarizing film, and (4) a plurality of winding portions after the removal of the release film; the second substrate (four) mechanism and the second substrate transfer mechanism are disposed on the first and second film transfer mechanisms Correction correction date: 2011/3/11 The upper part i is attached to the substrate by the polarizing film after the release film is removed, and the first bonding unit is provided between the first film conveying mechanism and the first substrate conveying mechanism. And the second bonding of the polarizing film-bonding substrate after removing the peeling film The portion is provided between the second film transport mechanism and the second substrate transport mechanism. In this case, since a plurality of winding portions and winding portions are provided, the amount of remaining material of the polarizing film in the winding of one side is reduced, and the raw material can be connected to the raw material provided on the other side winding portion. As a result, it is not necessary to stop the winding of the polarizing film, and the operation can be continued, so that the production efficiency can be improved.

Further, in the bonding apparatus of the polarizing film of the present invention, the winding portion is horizontally movable with respect to the core direction of the polarizing film and serves as the first winding portion and the second winding of the winding portion. The outlets are set side by side. Thereby, since the unwinding portion is horizontally moved in the direction of the winding core, it is not necessary to secure a space for moving the unwinding portion upward.
