Description

Polarizing film laminating apparatus and liquid crystal display manufacturing system having the same

The present invention relates to a polarizing film laminating apparatus and a liquid crystal display manufacturing system including the same.

Conventionally, liquid crystal display devices have been widely manufactured. In general, a polarizing film is bonded to a substrate (liquid crystal panel) used in a liquid crystal display device in order to control transmission or blocking of light. The polarizing film is bonded so that the absorption axes thereof are orthogonal.

As a method for bonding the polarizing film to the substrate, there is a so-called “chip-to-panel” method in which the polarizing film is bonded after being cut into a size corresponding to the substrate. However, this method has a disadvantage that the production efficiency is low because the polarizing films are bonded to the substrate one by one. On the other hand, as another method, there is a so-called “roll-to-panel” method in which a polarizing film is supplied to a conveyor roll and continuously bonded to a substrate. According to this method, bonding can be performed with high production efficiency.

As an example of a roll-to-panel method, Patent Document 1 discloses an optical display device manufacturing system. The said manufacturing system rotates a board | substrate after bonding an optical film (polarizing film) on the upper surface of a board | substrate, and bonds a polarizing film from a lower surface.

Japanese Patent No. 4307510 (issued on August 5, 2009)

However, the conventional apparatus has the following problems.

First, when a polarizing film is bonded to a substrate, the work is usually performed in a clean room in order to prevent foreign matters such as dust from entering the bonding surface. In the clean room, air is rectified. This is because it is necessary to bond the polarizing film in a state in which rectification is performed on the substrate in a downflow in order to suppress the yield reduction due to the foreign matter.

In this regard, the manufacturing system of Patent Document 1 has a configuration in which a polarizing film is bonded to the substrate from the upper surface and the lower surface. However, when bonding is performed from the upper surface of the polarizing film, there is a demerit that airflow (downflow) is hindered by the polarizing film and the rectification environment to the substrate is deteriorated. As an example of pasting from the upper surface of the polarizing film, FIGS. 10A and 10B show air velocity vectors in the top-paste type manufacturing system. In FIG. 10, area A is an area where an unwinding part for unwinding the polarizing film is installed, area B is an area through which the polarizing film mainly passes, and area C is peeled off from the polarizing film. This is an area in which a take-up unit or the like for winding the film is installed.

Also, clean air is supplied from a HEPA (High Efficiency Particulate Air) filter 40. In FIG. 10A, since the grating 41 through which clean air can pass is installed, the airflow can move in the vertical direction via the grating 41. On the other hand, in FIG. 10B, since the grating 41 is not installed, the airflow moves along the floor after contacting the floor at the bottom of FIG. 10B.

10 (a) and 10 (b), the areas A to C are arranged on the 2F (second floor) portion, and the clean air from the HEPA filter 40 is blocked by the polarizing film. Therefore, it is difficult to generate an airflow in the vertical direction with respect to the substrate passing through the 2F portion. On the other hand, the airflow vector in the horizontal direction is large (vector density is high). That is, it can be said that the rectification environment has deteriorated.

This invention is made | formed in view of the said conventional problem, Comprising: The objective is to provide the manufacturing system of a polarizing film bonding apparatus and a liquid crystal display device provided with the same which do not disturb a rectification environment. is there.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 9, but the present invention is not limited to this. First, the configuration of a manufacturing system (a manufacturing system for a liquid crystal display device) according to the present embodiment will be described below. The manufacturing system includes a bonding apparatus according to the present invention.

FIG. 1 is a cross-sectional view showing a manufacturing system. As shown in the figure, the manufacturing system 100 has a two-stage structure, a 1F (first floor) portion is a film transport mechanism 50, and a 2F (second floor) portion is a bonding apparatus 60 including a substrate transport mechanism. It has become.

<Film transport mechanism>
First, the film transport mechanism 50 will be described. The film transport mechanism 50 plays the role of unwinding the polarizing film (polarizing plate) and transporting it to the nip rolls 6 · 6a and 16 · 16a and winding up the peeling film that is no longer needed. On the other hand, the bonding device 60 plays a role of bonding the polarizing film unwound by the film transport mechanism 50 to the substrate (liquid crystal panel) 5.

The film transport mechanism 50 includes a first film transport mechanism 51 and a second film transport mechanism 52. The 1st film conveyance mechanism 51 conveys a polarizing film to the nip roll 6 * 6a which bonds a polarizing film to the lower surface of the board | substrate 5 first. On the other hand, the second film transport mechanism 52 transports the polarizing film to the bottom surface of the inverted substrate 5.

The first film transport mechanism 51 includes a first unwinding unit 1, a second unwinding unit 1a, a first winding unit 2, a second winding unit 2a, a half cutter 3, a knife edge 4, and a defect film winding roller. 7 · 7a. The first unwinding unit 1 is provided with a polarizing film original, and the polarizing film is unwound. A known polarizing film may be used as the polarizing film. Specifically, a polyvinyl alcohol film is dyed with iodine or the like, and a film stretched in a uniaxial direction can be used. Although it does not specifically limit as thickness of the said polarizing film, A polarizing film 5 micrometers or more and 400 micrometers or less can be used preferably.

In the original film of the polarizing film, the direction of the absorption axis is located in the flow direction (MD direction). The polarizing film has a pressure-sensitive adhesive layer protected by a release film. As the release film (also referred to as a protective film or a separator), a polyester film, a polyethylene terephthalate film, or the like can be used. Although it does not specifically limit as thickness of the said peeling film, The peeling film of 5 micrometers or more and 100 micrometers or less can be used preferably.

Since the manufacturing system 100 includes two unwinding portions and two unwinding portions corresponding to the unwinding portions, the first unwinding portion 1 has a low remaining amount of raw material. It is possible to connect the original fabric provided in the two unwinding portions 1 a to the original fabric of the first unwinding portion 1. As a result, it is possible to continue the operation without stopping the unwinding of the polarizing film. With this configuration, production efficiency can be increased. Of course, a plurality of unwinding sections and winding sections may be provided, and three or more winding sections may be provided.

Half cutter (cutting unit) 3 half-cuts a polarizing film (a film laminate composed of a polarizing film, a pressure-sensitive adhesive layer and a peeling film) protected by a peeling film, and cuts the polarizing film and the pressure-sensitive adhesive layer. As the half cutter 3, a known member may be used. Specifically, a cutter, a laser cutter, etc. can be mentioned. After the polarizing film and the pressure-sensitive adhesive layer are cut by the half cutter 3, the release film is removed from the polarizing film by the knife edge (removal part) 4.

An adhesive layer is applied between the polarizing film and the release film. After the release film is removed, the adhesive layer remains on the polarizing film side. The pressure-sensitive adhesive layer is not particularly limited, and examples thereof include acrylic, epoxy, and polyurethane pressure-sensitive adhesive layers. The thickness of the pressure-sensitive adhesive layer is not particularly limited, but is usually 5 to 40 μm.

On the other hand, the 2nd film conveyance mechanism 52 is the structure similar to the 1st film conveyance mechanism 51, and is the 1st unwinding part 11, the 2nd unwinding part 11a, the 1st winding part 12, and the 2nd winding part 12a. , Half cutter 13, knife edge 14 and defect

film winding rollers

17 and 17 a. About the member which attached | subjected the same member name, the effect | action same as the member in the 1st film conveyance mechanism 51 is shown.

As a preferred embodiment, the manufacturing system 100 includes a cleaning unit 71. The cleaning unit 71 cleans the substrate 5 before the polarizing film is bonded to the lower surface of the substrate 5 by the nip rolls 6 and 6a. As the cleaning unit 71, a known cleaning unit composed of a nozzle and a brush for injecting a cleaning liquid may be used. By cleaning the substrate 5 immediately before the bonding by the cleaning unit 71, the bonding can be performed in a state where there are few adhered foreign substances on the substrate 5.

Next, the knife edge 4 will be described with reference to FIG. FIG. 2 is a cross-sectional view showing a peripheral portion of the nip rolls 6 and 6a in the manufacturing system 100. FIG. FIG. 2 shows a situation where the substrate 5 is conveyed from the left direction and the polarizing film 5a having an adhesive layer (not shown, the same hereinafter) is conveyed from the lower left direction. The polarizing film 5a is provided with a release film 5b. The polarizing film 5a and the pressure-sensitive adhesive layer are cut by the half cutter 3, and the release film 5b is not cut (half cut).

The knife edge 4 is installed on the peeling film 5b side. The knife edge 4 is an edge-shaped member for peeling the peeling film 5b, and the polarizing film 5a and the peeling film 5b having a low adhesive force are peeled off along the knife edge 4.

Thereafter, the release film 5b is wound around the first winding portion 2 in FIG. In addition, it can replace with a knife edge and can also use the structure which winds up a peeling film using an adhesion roller. In that case, the winding efficiency of a peeling film can be improved by providing an adhesive roller in two places similarly to a winding part.

<Bonding device>
Next, the bonding apparatus 60 will be described. The bonding apparatus 60 conveys the board | substrate 5, and bonds the polarizing film conveyed by the film conveyance mechanism 50 to a board | substrate. Although not shown, clean air is supplied to the upper surface of the substrate 5 in the bonding apparatus 60. That is, downflow rectification is performed. Thereby, it is possible to perform conveyance and bonding of the substrate 5 in a stable state.

The bonding apparatus 60 is provided on the upper part of the film transport mechanism 50. Thereby, space saving of the manufacturing system 100 can be achieved. Although not shown, a substrate transport mechanism including a conveyor roll is installed in the bonding device 60, whereby the substrate 5 is transported in the transport direction (the first substrate transport device 61 and the second substrate described later in FIG. 6). The substrate transfer device 62 corresponds to a substrate transfer mechanism).

In the manufacturing system 100, the substrate 5 is transported from the left side, and then transported from the right side in the drawing, that is, from the top of the first film transport mechanism 51 to the top of the second film transport mechanism 52. The substrate 5 has a rectangular shape, and the ratio of the long side and the short side is not particularly limited, but may be, for example, a ratio of 16: 9 to 4: 3. Moreover, as a specific example of the board | substrate 5, the glass substrate panel of an organic electroluminescent panel and a liquid crystal cell can be mentioned, for example.

Between the film conveyance mechanism 50 and the bonding apparatus 60, the nip roll (1st bonding part) 6 * 6a and the nip roll (2nd bonding part) 16 * 16a which are bonding parts are each provided. The nip rolls 6, 6 a and 16, 16 a are members that serve to bond a polarizing film from which the release film has been removed to the lower surface of the substrate 5. In addition, since a polarizing film is bonded to both surfaces of the substrate 5 from the lower surface, the substrate 5 is reversed by the reversing mechanism 65 after being bonded by the nip rolls 6 and 6a. The reversing mechanism 65 will be described later.

The polarizing film conveyed to the nip rolls 6 and 6a is bonded to the lower surface of the substrate 5 through an adhesive layer. As the nip rolls 6 and 6a, known configurations such as a pressure roll and a pressure roll can be employed. Moreover, what is necessary is just to adjust the pressure and temperature at the time of bonding in the nip rolls 6 and 6a suitably. The configuration of the nip rolls 16 and 16a is the same. Although not shown, in the manufacturing system 100, as a preferable configuration, a defect display (mark) detection unit is provided between the first unwinding unit 1 and the half cutter, and a polarizing film having a defect is detected. It has a configuration.

In addition, the said defect display is provided at the time of the 1st unwinding part 11 or the 2nd unwinding part 11a rather than a defect display detection part by performing the detection at the time of original film production of a polarizing film, and providing a defect display. It attaches | subjects to a polarizing film by a fault display provision part. The defect display imparting unit includes a camera, an image processing device, and a defect display forming unit. First, a polarizing film is imaged by the camera, and the presence or absence of a defect can be inspected by processing the imaging information. Specific examples of the drawback include foreign matters such as dust and fish eyes. When a defect is detected, a defect display is formed on the polarizing film by the defect display forming unit. A mark such as ink is used as the defect display.

Further, a bonding avoiding unit (not shown) discriminates the mark with a camera and transmits a stop signal to the bonding apparatus 60 to stop the conveyance of the substrate 5. Thereafter, the polarizing film in which the defect is detected is not bonded by the nip rolls 6 and 6a and is wound by the defect film winding roller (collecting unit) 7 and 7a. Thereby, pasting with substrate 5 and a polarizing film which has a fault can be avoided. If the said series of structures are provided, since the bonding with the polarizing film which has a fault, and the board | substrate 5 can be avoided, a yield can be improved and it is preferable. A publicly known inspection sensor can be used suitably as a fault detection part and a pasting avoidance part.

As shown in FIG. 1, after the substrate 5 is reversed by the reversing mechanism 65, the substrate 5 is conveyed to the nip rolls 16 and 16a. Then, a polarizing film is bonded to the lower surface of the substrate 5. As a result, the polarizing film is bonded to both surfaces of the substrate 5, and the two polarizing films are bonded to both surfaces of the substrate 5 with different absorption axes. Thereafter, if necessary, the both sides of the substrate 5 are inspected for misalignment. The inspection can be usually performed by an inspection unit equipped with a camera.

Thus, in the manufacturing system 100, when the polarizing film is bonded to the substrate 5, the bonding is performed from the lower surface of the substrate 5, and the rectifying environment to the substrate 5 is not hindered. For this reason, foreign matter mixing into the bonding surface of the substrate 5 can also be prevented, and more accurate bonding is possible.

FIG. 3 (a) and FIG. 3 (b) show the velocity vector of the airflow in the under-paste type manufacturing system similar to the present invention. Regions A in FIGS. 3 (a) and 3 (b) are regions where the unwinding part is installed, region B is a region through which the polarizing film mainly passes, and region C is a region where the winding unit and the like are installed. It is. Further, clean air is supplied from the HEPA filter 40. In FIG. 3A, since the grating 41 through which clean air can pass is installed, the airflow can move in the vertical direction via the grating 41. On the other hand, in FIG. 3B, since the grating 41 is not installed, the airflow moves along the floor after contacting the floor.

Since the manufacturing system shown in FIGS. 3 (a) and 3 (b) is a bottom-attached type, the air current from the HEPA filter 40 is not hindered by the polarizing film as shown in FIGS. 10 (a) and 10 (b). For this reason, the direction of the airflow vector is almost directed toward the substrate, and it can be said that a preferable rectification environment is realized in the clean room. In FIG. 3 (a), the grating 41 is installed and not installed in FIG. 3 (b), but both drawings show the same preferable state. 3 and 10, the substrate transport mechanism is formed horizontally, but is not installed as a series of structures. For this reason, the airflow can pass between the substrate transport mechanisms. After the substrate is held by a reversing mechanism to be described later, the substrate is transferred between the substrate transport mechanisms.

Moreover, in the manufacturing system 100, the board | substrate 5 is first conveyed by a long side opening (a long side is orthogonal to a conveyance direction), and is conveyed by a short side opening (a short side is orthogonal to a conveyance direction) after that. It has become.

<Reversing mechanism>
The reversing mechanism 65 is a member that reverses the substrate 5 transported by the first substrate transport mechanism and places it on the second substrate transport mechanism. The first substrate transport mechanism and the second substrate transport mechanism are arranged in the same direction. FIG. 4 is a perspective view showing the reversing mechanism 65. The reversing mechanism 65 includes a first substrate reversing unit (substrate reversing unit) 67 and a second substrate reversing unit (substrate reversing unit) 68.

The first substrate reversing portion 67 has a rod shape and includes a suction portion 66. The first substrate reversing unit 67 can rotate in its own axial direction, and can move the substrate 5 in a direction perpendicular to the axis via the adsorption unit 66. The first substrate reversing unit 67 is connected to the second substrate reversing unit 68. The connecting portion can be driven, and the position of the first substrate reversing unit 67 can be changed, and the position of the substrate 5 can be changed.

In addition to the two arm structures, the second substrate reversing part 68 has a structure in which the base part can be rotated horizontally. The substrate 5 can be moved in the vertical direction by the two arm structures, and the substrate 5 can be rotated in the horizontal direction by the rotation of the base portion.

In the present embodiment, the structure of the first substrate reversing unit 67 and the second substrate reversing unit 68 is shown as the substrate reversing unit, but the substrate reversing unit is not limited to this configuration. For example, a robot arm having a control unit can be used as a preferred form. When a robot arm is used, it is preferable because a more precise operation of the substrate 5 is possible. A known robot arm can be used as the robot arm.

Next, the reversal of the substrate 5 by the first substrate reversing unit 67 and the second substrate reversing unit 68 will be described. FIG. 13 is a perspective view showing a trajectory when the substrate 5 is reversed. FIG. 13A corresponds to the state of the substrate 5 in FIG. The suction unit 66, the first substrate reversing unit 67, and the second substrate reversing unit 68 are not shown so that the trajectory of the substrate 5 can be easily grasped.

First, the substrate 5 is transferred from the first substrate transfer mechanism with the short side of the substrate 5 along the transfer direction. As shown in FIG. 13A, the substrate 5 stops before the first substrate reversing unit 67 (not shown), and the adsorption unit 66 is adsorbed on the surface of the substrate 5. Finally, as shown in FIG. 13D, the substrate 5 has the second substrate transport mechanism such that the short side along the transport direction of the first substrate transport mechanism is along the direction orthogonal to the transport direction. Placed in.

The first substrate reversing unit 67 and the second substrate reversing unit 68 are configured so that the substrate 5 draws a curve so as to change the state of the substrate 5 in FIG. 13A to the state of the substrate 5 in FIG. Move. That is, the substrate 5 is moved by a gentle 1 operation. Therefore, the reversal of the substrate 5 in the present embodiment does not involve a linear movement, for example, a reversal movement in a direction along one side of the substrate 5. Further, this operation is not an operation in which the two operations of reversing the substrate and turning in the horizontal direction of the substrate are continued, and these two operations are not performed simultaneously.

As shown in FIGS. 13B to 13D, the substrate 5 in FIG. 13A has one short side (on the left side in the figure) as the inside and the other (right side in the figure) the short side as the outside. Moved. Specifically, the rotation drive system of each axis of the ropot shown in FIG. 4 is turned off, and each axis of the robot can be moved by the operator, and the angle and displacement of each axis of the moved robot. In the teaching mode in which is detected by the sensor, the posture of the substrate 5 and the angle and displacement of each axis of the robot that realizes the posture are taught and stored by the operator as described below. In FIG. 13A, the substrate 5 is lifted from the horizontal plane where the substrate 5 is located, and the substrate 5 is moved in an inclined state so that the outer short side is higher than the inner short side. . The substrate 5 ′ indicates the position after the substrate 5 has moved. A curve 69 indicates the locus of the substrate 5 connecting the corresponding vertices in the substrate 5 and the substrate 5 ′. The first substrate reversing unit 67 and the second substrate reversing unit 68 move the substrate 5 so as to draw a curve. In other words, it can be said that the substrate moves along a curved locus. The above curve is a circular arc, and is not a straight line but a smooth locus. In addition to the teaching described above, the angle and displacement data of each axis of the robot is created and stored in advance in the ROM of the control device so that the substrate moves in accordance with the arc locus shown in FIG. It is also possible to adopt an embodiment in which the substrate is reversed and moved according to the arc locus shown in FIG.

The substrate 5 is finally moved to the state shown in FIG. 13 (d) through the state shown in FIGS. 13 (b) and 13 (c). The arrangement of the substrate 5 in FIG. 13D is an arrangement in which the substrate 5 in FIG. 13A is inverted so that the short side along the transport direction becomes the long side.

Further, a process of changing the arrangement of the substrate 5 will be described with reference to FIG. FIGS. 14A to 14D are plan views showing the process of reversing the substrate 5 by the reversing mechanism 65. The arrangement of the substrate 5 in FIGS. 14 (a) to 14 (d) corresponds to the arrangement of the substrate 5 in FIGS. 13 (a) to (d), respectively.

FIG. 14 is a plan view showing the rotation process of the substrate 5 in FIG. FIG. 14 shows the first substrate transport mechanism 61 and the second substrate transport mechanism 62 in addition to the reversing mechanism 65. The first substrate transport mechanism 61 and the second substrate transport mechanism 62 are provided with a conveyor roll, whereby the substrate 5 is transported. Further, the first substrate transport mechanism 61 and the second substrate transport mechanism 62 are arranged in the same direction. That is, it does not have a complicated structure such as an L shape. Therefore, the bonding apparatus 60 according to the present invention is very simple to install and is excellent in area efficiency.

First, as shown in FIG. 14A, the suction portion 66 is sucked onto the surface of the substrate 5, and the surface of the substrate 5 is held. Thereafter, the substrate 5 is moved so as to follow the locus of the curve 69 shown in FIGS. 13A to 13C so that the substrate 5 shown in FIG. 14D is arranged. After the substrate 5 reaches the position shown in FIG. 13D, the substrate 5 is unloaded by releasing the suction of the suction unit 66, and then the substrate 5 is transported by the second substrate transport mechanism 62. The Then, the reversing mechanism 65 returns to the position of FIG. 6A and reverses the other substrates 5 that are sequentially transported by the same operation.

According to the reversing mechanism 65 of the present embodiment, as a result, (1) the substrate 5 is reversed by one operation, and (2) the long side or the short side along the transport direction of the first substrate transport mechanism 61 Are arranged along a direction orthogonal to the transport direction. For this reason, two states of the substrate 5 can be changed by one operation.

Since the two reversing mechanisms 65 produce two actions in this way, the substrate 5 can be reversed with a short tact time. That is, since the one reversing mechanism 65 reverses the substrate 5 and changes the side along the transport direction, the line length in the bonding apparatus 60 is not compressed.

Further, after the reversing mechanism 65 reverses the substrate 5 and changes the sides along the transport direction, the polarizing film can be bonded to the substrate 5 from the lower surface by the nip rolls 16 and 16a. Thereby, a polarizing film can be bonded together from the lower surface with respect to both surfaces of the board | substrate 5 by the bonding apparatus 60, and a rectification environment is not prevented.

In FIG. 14, the first substrate transport mechanism 61 and the second substrate transport mechanism 62 are not arranged in a straight line but have adjacent structures. Compared with the substrate 5 in FIG. 14A and the substrate 5 in FIG. 14D, a straight line connecting a plurality of midpoints between corresponding vertices is a substrate in the first substrate transport mechanism 61. The angle is 45 ° with respect to the conveyance direction 5. Thus, the transport direction with the first substrate transport mechanism 61 and the transport direction of the substrate 5 with the second substrate transport mechanism 62 are in the same direction, that is, they are parallel but not on the same straight line. . Note that the arrangement of the substrate 5 in FIG. 14D is merely an example, and does not need to be strictly the arrangement.

The reversing mechanism of the embodiment shown in FIGS. 5 to 7 is inserted in the reciprocating part 671 and a reciprocating part 671 that can expand and contract in one direction with respect to the base part 670 in the vertical direction in the figure. Within a range of 180 degrees by a rotating part 672 that rotates within a range of 90 degrees on a horizontal plane, and a motor 6733 that is rotatably inserted into two

support parts

6731 and 6732 disposed at the upper end of the rotating part 672. A substrate reversing member 673 as a substrate reversing unit integrally disposed on a rotating shaft 6734 that is driven to rotate and integrally connected to a motor 6630 disposed at one end of the base member 660 of the substrate supporting device 66. Consists of.

The rotating shaft 6734 driven to rotate by the motor 6733 constitutes the reversing shaft of the substrate reversing portion 673 of the reversing mechanism, is inserted in the reciprocating portion 671, and rotates within a range of 90 degrees on the horizontal plane in the drawing. The rotating part 672 is an arrangement changing member, and the rotation axis of the rotating part 672 is an arrangement changing axis.

The substrate reversing member 673 is reversed 180 degrees from the state extending in the width direction of the downstream end of the first substrate transport mechanism 61 shown in FIGS. 5 and 7 to the front side in the figure by a control signal from the control device. However, since the rotating portion 672 is driven to rotate 90 degrees counterclockwise at that time, when rotated 90 degrees, it extends in the conveying direction at the upstream end of the second substrate conveying mechanism 62 as shown in FIG. In this state, the substrate 5 transported to the downstream end of the first substrate transport mechanism 61 is disposed at the upstream end of the second substrate transport mechanism 62 with the arrangement direction changed by 90 degrees to enable transport. is there.

In the state shown in FIG. 5, the rotation portion 672 rotates counterclockwise in a plurality of, for example, four divided portions 61 A divided in the width direction of the downstream end portion of the first substrate transport mechanism 61. A plurality of, for example, three protrusions of the substantially E-shaped first and second comb-shaped members constituting the first and

second support members

Moreover, the said edge part is equipped with the conveyance means which conveys the board | substrate 5 to the board | substrate mounting part 61a, Specifically, a conveyor roll can be mentioned, for example.

The substrate platform 61a is a place where the substrate 5 is transported before the substrate 5 is moved by the reversing mechanism 65. According to this structure, the substrates 5 transported to the first substrate transport mechanism 61 are transported alternately to the two substrate platforms 61a by the transport means. Two pairs of substrate placement portions 61 a and reversing mechanisms 65 are provided, and the plurality of substrates 5 that are alternately conveyed to the two reversing mechanisms 65 are sequentially moved to the second substrate conveying mechanism 62.

In the modified example, the two substrate platforms 61 a are provided along both horizontal directions of the first substrate transport mechanism 61, so the inverted substrate 5 is along the transport direction of the first substrate transport mechanism 61. Will be placed. Therefore, the first substrate transport mechanism 61 and the second substrate transport mechanism 62 can be arranged on a straight line.

The sticking deviation inspection device 72 is constituted by a camera and an image processing device, and the camera is installed at the bonding position of the substrate 5 on which the polarizing film is bonded by the nip rolls 16 and 16a. The board | substrate 5 is image | photographed with the said camera and the presence or absence of sticking misalignment to the board | substrate 5 can be test | inspected by processing the image | photographed image information (sticking misalignment inspection process, S3 of FIG. 9). Note that as the misalignment inspection apparatus 72, a conventionally known misalignment inspection apparatus can be used.

The bonded foreign matter automatic inspection device 73 inspects the presence or absence of foreign matter on the bonded substrate 5. The bonded foreign matter automatic inspection device 73 is configured by a camera and an image processing device, like the misalignment inspection device 72, and transports the second substrate of the substrate 5 after the polarizing film is bonded by the nip rolls 16 and 16a.

The sorting and conveying device 74 determines the presence or absence of sticking misalignment and foreign matter based on the inspection results from the sticking misalignment inspection device 72 and the bonded foreign matter automatic inspection device 73. The sorting and conveying device 74 only needs to receive an output signal based on the inspection result from the sticking misalignment inspection device 72 and the bonding foreign matter automatic inspection device 73 and can sort the bonded substrates 5 into non-defective products or defective products. . Therefore, a conventionally known sorting and conveying system can be used.

In the manufacturing system of the liquid crystal display device, as a preferred mode, both the misalignment and foreign matter are detected. When it is determined that the misalignment or foreign matter has been inspected (YES), the bonded substrate 5 is not used. Sorted as good (S7).
