Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polarizing film joining apparatus and a manufacturing system of a liquid crystal display device having the joining apparatus.

The present invention relates to a polarizing film joining apparatus and a manufacturing system of the liquid crystal display apparatus having the joining apparatus.

Conventionally, liquid crystal display devices are 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 its absorption axes are orthogonal.

As a method for bonding a polarizing film to a substrate, there is a so-called chip to panel method in which a polarizing film is cut to a size corresponding to a substrate and then bonded. However, in this method, since the polarizing films are bonded one by one to the substrate, there is a drawback that the production efficiency is low. On the other hand, as another method, a so-called roll-to-panel method in which a polarizing film is supplied to a conveyor roll and is continuously bonded to a substrate is exemplified. 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 a manufacturing system of an optical display device. In the manufacturing system, an optical film (polarizing film) is bonded to the upper surface (upper surface) of the substrate, and then the substrate is turned to join the polarizing film from the lower surface.

Patent Document 1: Japanese Patent No. 4307510 (issued on Aug. 5, 2009)

However, the conventional apparatus has the following problems.

First, when a polarizing film is bonded to a substrate, work is usually performed in a clean room in order to prevent foreign matter such as dust from mixing into the bonding surface. In the clean room, air is rectified. This is because it is necessary for the polarizing film to be bonded in a state in which the substrate is rectified by a down flow with respect to the substrate in order to suppress the yield reduction due to foreign matter.

Regarding this point, the manufacturing system of Patent Document 1 has a configuration in which a polarizing film is bonded to the substrate from the upper and lower surfaces. However, in the case of joining from the upper surface of the polarizing film, there is a disadvantage that the airflow (downward flow) is interrupted by the polarizing film, and the rectifying environment to the substrate is deteriorated. Figs. 20A and 20B show speed vectors of the airflow in the upper bonded type production system as examples of bonding from the upper surface of the polarizing film. Fig. 20, a region A is a region in which a winding portion for winding a polarizing film is provided, a region B is a region through which a polarizing film is mainly passed, and a region C is a winding portion for winding a separation film, And the like.

Clean air is supplied from the HEPA (High Efficiency Particulate Air) filter 40. 20 (a), since a grating 41 through which clean air can pass is provided, it is possible for the airflow to move in the vertical direction through the grating 41. On the other hand, in FIG. 20 (b), since the grating 41 is not provided, the airflow moves along the bottom after contacting the bottom of the lowermost part of FIG. 20 (b).

20A and 20B, the regions A to C are disposed in the 2F (second layer) portion, and the clean air from the HEPA filter 40 is blocked by the polarizing film. Therefore, it is difficult to generate an air current directed 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 (the density of the vector is high). That is, it can be said that the rectification environment is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a polarizing film joining apparatus which does not disturb the rectifying environment and a manufacturing system of the liquid crystal display apparatus having the joining apparatus.

That is, since the polarizing film can be bonded from both the lower surface and the lower surface of the substrate, the rectifying environment is not disturbed.

[Example 1]

An embodiment of the present invention will be described with reference to Figs. 1 to 9 as follows, but the present invention is not limited thereto. First, the construction of the manufacturing system (manufacturing system of liquid crystal display device) according to the present embodiment will be described below. The manufacturing system includes the bonding apparatus according to the present invention.

1 is a sectional view showing a manufacturing system. As shown in FIG. 1, the manufacturing system 100 has a two-stage structure, and the 1F (first layer) portion is a film transport mechanism 50 and the 2F (second layer) (60).

<Film transport mechanism>

First, the film transport mechanism 50 will be described. The film conveying mechanism 50 conveys the polarizing film (polarizing plate) to the nip rolls (6 · 6a and 16 · 16a), and unwinds the unnecessary peeling film It plays a role of taking. On the other hand, the joining device 60 serves to join 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 film transport mechanism 52. The first film transporting mechanism 51 transports the polarizing film to the nip roll 6 · 6a that first attaches the polarizing film to the lower surface of the substrate 5. On the other hand, the second film transport mechanism 52 transports the polarizing film to the lower surface of the inverted substrate 5.

The first film transporting mechanism 51 includes a first winding portion 1, a second winding portion 1a, a first winding portion 2, a second winding portion 2a, a half cutter 3, (4), and a defect film winding roller (7 · 7a). The first winding unit 1 is provided with a polarizing film raw material, and the polarizing film is wound therearound. As the polarizing film, a known polarizing film may be used. Concretely, a film or the like which is stained with iodine or the like and stretched in the uniaxial direction can be used for the polyvinyl alcohol film. The thickness of the polarizing film is not particularly limited, but a polarizing film having a size of 5 탆 or more and 400 탆 or less can be preferably used.

In the disk of the polarizing film, the direction of the absorption axis is located in the flow direction (MD direction). The pressure-sensitive adhesive layer of the polarizing film is protected by a release film. As the peeling film (also referred to as a 'protective film' or a 'separator'), a polyester film, a polyethylene terephthalate film, or the like can be used. The thickness of the peeling film is not particularly limited, but a peeling film having a thickness of 5 占 퐉 or more and 100 占 퐉 or less can be preferably used.

Since the manufacturing system 100 is provided with two unwinding portions and two winding portions corresponding to the winding portions, when the remaining amount of the original of the first winding portion 1 is small, It is possible to connect the provided disc to the disc of the first winding unit 1. [ As a result, it is possible to continue the operation without stopping the unwinding of the polarizing film. With this configuration, it is possible to increase the production efficiency. Further, a plurality of the winding portions and the winding portions may be provided, and three or more winding portions may be provided.

The half cutter (cut portion) 3 cuts the polarizing film and the pressure-sensitive adhesive layer by half cutting the polarizing film (film laminate composed of polarizing film, pressure-sensitive adhesive layer and release film) protected with a release film. As the half cutter 3, a known member may be used. Specifically, a blade, a laser cutter and the like 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 (removing unit 4).

A pressure sensitive adhesive layer is applied between the polarizing film and the release film, and after the release film is removed, the pressure sensitive 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 占 퐉.

On the other hand, the second film transport mechanism 52 has the same structure as the first film transport mechanism 51 and has a first winding section 11, a second winding section 11a, a first winding section 12, A twin winding section 12a, a half cutter 13, a knife edge 14, and a defect film winding roller 17 占 7a. And the same member name is given to the member in the first film transport mechanism 51.

In a preferred form, the manufacturing system 100 is provided with a cleaning section 71. The cleaning section 71 cleans the substrate 5 before bonding the polarizing film to the lower surface of the substrate 5 by the nip roll 6 · 6a. As the cleaning section 71, a known cleaning section composed of a nozzle, a brush, and the like for spraying the cleaning liquid may be used. By cleaning the substrate 5 immediately before the bonding by the cleaning portion 71, the bonding can be performed in a state where the foreign matter on the substrate 5 is small.

Next, the knife edge 4 will be described with reference to Fig. Figure 2 is a cross-sectional view showing the peripheral portion of the nip roll 6 · 6a in the manufacturing system 100. Fig. 2 shows a situation in which the polarizing film 5a carrying the substrate 5 from the left direction and having the pressure-sensitive adhesive layer from the lower left direction (not shown, hereafter the same) is transported. The polarizing film 5a is provided with a peeling film 5b and the polarizing film 5a and the pressure-sensitive adhesive layer are cut by the half cutter 3 and the peeling film 5b is not cut (half cut).

On the side of the peeling film 5b, a knife edge 4 is provided. The knife edge 4 is an edge member for peeling the peeling film 5b and the peeling film 5b having a low adhesive strength to the polarizing film 5a is peeled off along the knife edge 4. [

Thereafter, the peeling film 5b is wound around the first winding part 2 in Fig. It is also possible to use a constitution in which a peeling film is wound by using an adhesive roller instead of a knife edge. In this case, similarly to the winding section, by providing the adhesive rollers at two places, the winding efficiency of the release film can be increased.

<Bonding device>

Next, the joining apparatus 60 will be described. The joining apparatus 60 conveys the substrate 5 and joins the polarizing film conveyed by the film conveying mechanism 50 to the substrate. Although not shown, clean air is supplied to the upper surface of the substrate 5 in the joining apparatus 60. That is, the downward flow is rectified. This makes it possible to carry and bond the substrate 5 in a stable state.

The joining device (60) is provided on the upper part of the film conveying mechanism (50). This makes it possible to save space in the manufacturing system 100. Although not shown, the bonding apparatus 60 is provided with a substrate transporting mechanism having a conveyor roll, whereby the substrate 5 is transported in the transport direction (the first substrate transport mechanism 61 described later in FIG. 6) The second substrate transport mechanism 62 corresponds to the substrate transport mechanism).

In the manufacturing system 100, the substrate 5 is transported from the left side and then transported from the upper side of the first film transport mechanism 51 to the upper side 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. Specific examples of the substrate 5 include an organic EL panel and a glass substrate panel of a liquid crystal cell.

A nip roll (first joint portion 6 · 6a) and a nip roll (second joint portion 16 · 16a) are provided between the film transport mechanism 50 and the bonding apparatus 60, respectively. The nip rolls 6 · 6a and 16 · 16a are members that serve to bond the polarizing film from which the release film has been removed to the lower surface of the substrate 5. After the polarizing film is bonded to the both surfaces of the substrate 5 by the nip roll 6 · 6a, the substrate 5 is reversed by the reversing mechanism 65. The reversing mechanism 65 will be described later.

The polarizing film conveyed to the nip roll 6 · 6a is bonded to the lower surface of the substrate 5 via the pressure-sensitive adhesive layer. As the nip roll 6 · 6a, known configurations such as a press roll and a press roll can be adopted, respectively. The pressure and temperature at the time of joining in the nip roll 6 · 6a may be appropriately adjusted. The same is true for the configuration of the nip roll 16 · 16a. Although not shown, in the manufacturing system 100, a defective mark (mark) detecting unit is provided between the first winding unit 1 and the half cutter, and a defective polarizing film is detected .

Further, the defect display is detected at the time of preparing the original of the polarizing film to give defect display. Or is attached to the polarizing film by a defect display portion provided on the first winding portion 11 or the second winding portion 11a side of the defect indication detecting portion. The defect display assigning section is constituted by a camera, an image processing apparatus, and a defect display forming section. First, the polarizing film is photographed by the camera, and the presence or absence of a defect can be checked by processing the photographic information. Specific examples of the drawbacks include foreign matters such as dust, fish eyes, and the like. When a defect is detected, a defect display is formed on the polarizing film by the defect display forming portion. Marks such as ink are used as defect marks.

Further, the unshown jointed skin discriminates the mark by the camera and transmits a stop signal to the joining apparatus 60 to stop the conveyance of the substrate 5. [ Thereafter, the polarizing film on which the defect has been detected is not wound by the nip roll 6 · 6a but is wound by the defect film winding roller (recovery portion 7 · 7a). As a result, it is possible to avoid the bonding between the substrate 5 and the polarizing film having a defect. If the series of constitutions are provided, it is possible to avoid the bonding between the polarizing film having defects and the substrate 5, which is preferable because the yield can be increased. A well-known inspection sensor can suitably be used as the defect detecting portion and the bonded skin.

As shown in Fig. 1, the substrate 5 is transported to the nip roll 16 · 16a after the substrate 5 is inverted by the reversing mechanism 65. Then, the 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 two polarizing films are bonded to the both surfaces of the substrate 5 with different absorption axes. Thereafter, if necessary, inspection is performed on both surfaces of the substrate 5 to see if any deviation occurs. The inspection may be performed by an inspection unit having a camera, for example.

As described above, in the manufacturing system 100, when the polarizing film is bonded to the substrate 5, bonding is performed from the lower surface of the substrate 5, and the rectifying environment to the substrate 5 is not disturbed. Therefore, it is also possible to prevent foreign matter from entering the bonding surface of the substrate 5, thereby enabling more accurate bonding.

Figures 3 (a) and 3 (b) show the velocity vectors of the airflow in the same bottom joint type manufacturing system as the present invention. In FIG. 3A, the area A is the area where the winding part is provided, the area B is the area where the polarizing film mainly passes, and the area C is the area where the winding part is installed. Clean air is supplied from the HEPA filter 40. 3 (a), since the grating 41 through which clean air can pass is provided, it is possible for the airflow to move in the vertical direction through the grating 41. On the other hand, in FIG. 3 (b), since the grating 41 is not provided, the airflow moves along the floor after coming into contact with the floor.

Since the manufacturing system shown in Figs. 3A and 3B is of the bottom bonding type, as shown in Figs. 20A and 20B, the airflow from the HEPA filter 40 is blocked by the polarizing film It does not. Therefore, it can be said that the direction of the airflow vector is almost in the direction toward the substrate, and a preferable rectifying environment is realized in the clean room. 3 (a), a grating 41 is provided, and although not shown in FIG. 3 (b), both of the drawings show the same preferable state. In Figs. 3 and 20, the substrate transport mechanism is formed horizontally, but it is not provided in a series structure. Therefore, the airflow can pass between the substrate transport mechanisms. The substrate is held by a reversing mechanism, which will be described later, and is then transferred between the substrate transport mechanisms.

In the manufacturing system 100, first, the substrate 5 is transported in a long width (the long side is perpendicular to the transport direction) and then the short side width (the short side is perpendicular to the transport direction) .

<Substrate Supporting Device>

As the adsorption portion 66S, a known adsorption portion can be used, and for example, an adsorption portion of the air suction type can be used.

Other aspects of the substrate support member will be described below.

The substrate supporting portion is a member for supporting the substrate 5, and can sandwich the mounted substrate. In addition, the substrate supporting portion is provided with a sucking means for sucking the substrate 5 in a preferred form. As the adsorption means, known ones can be used. For example, an adsorption means of the air suction type can be used. The substrate supporting portion is constituted by a pipe-shaped arm and suction means, and air sucked by the suction means passes through the arm. However, the shape of the arm and the suction means is not limited to the configuration.

In addition, the substrate supporting portion has a structure in which two suction means are provided on the arm, and a pair of arm groups each consisting of three arms is provided. Four adsorption means are arranged on the diagonal line of the substrate 5, and two adsorption means are arranged between the adsorption means in the longitudinal direction of the substrate 5.

It is also possible of course to change the installation location of the absorption means to the central portion of the substrate 5 or to change it around the end of the substrate 5. [

When the substrate reversal unit does not mount the substrate 5, the distance between the arm groups is increased so that the substrate 5 can be received (hereinafter, this state will be referred to as &quot; standby state &quot;). On the other hand, the substrate inverting section 67 is also in a state in which the distance between the arm groups is also widened. Further, the distance between the arm groups may be narrowed in order to sandwich the substrate 5 between the pair of arm groups. In this way, the distance between the arm groups can be changed. To this end, the substrate support unit has a motor, and the rotation movement of the motor is changed to linear motion to change the distance between the arm groups. Further, if the distance between the arm groups can be changed, it is also possible to use a configuration having a motor.

<Reversing mechanism>

The reversing mechanism 65 is a member which reverses the substrate 5 conveyed by the first substrate conveying mechanism and places it in the second substrate conveying 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. Fig. The inversion mechanism 65 includes a first substrate inverting portion (substrate inverting portion) 67 and a second substrate inverting portion (substrate inverting portion)

The first substrate inverting portion 67 is in the form of a rod and has a suction portion 66. [ The first substrate inverting portion 67 can rotate in its own axial direction and can move the substrate 5 in the direction perpendicular to the axis via the suction portion 66. [ In addition, the first substrate inverting portion 67 is connected to the second substrate inverting portion 68. The connecting portion can be driven and the position of the first substrate inverting portion 67 can be changed to change the position of the substrate 5. [

In addition to the two arm structures, the second substrate inverting portion 68 has a structure in which the pedestal portion is horizontally rotatable. 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 pedestal portion.

In this embodiment, the structure of the first substrate inverting portion 67 and the second substrate inverting portion 68 is shown as the substrate inverting portion, but the substrate inverting portion is not limited to this configuration. For example, a robot arm having a control unit can be used as a preferred form. In the case of using a robot arm, it is preferable because operation of the substrate 5 can be performed more precisely. A known robot arm can be used as the robot arm.

Next, the inversion of the substrate 5 by the first substrate inverting portion 67 and the second substrate inverting portion 68 will be described. 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 adsorption portion 66S, the first substrate inverting portion 67 and the second substrate inverting portion 68 are not shown so as to easily grasp the trajectory of the substrate 5. [

First, the substrate 5 is transported from the first substrate transport mechanism along the short side of the substrate 5 in the transport direction. The substrate 5 is stopped in front of the first substrate inverting portion 67 not shown and the sucking portion 66 is adsorbed on the surface of the substrate 5 as shown in Fig. The substrate 5 is finally disposed in the second substrate transport mechanism such that short sides along the transport direction of the first substrate transport mechanism are perpendicular to the transport direction as shown in Figure 13 (d) .

The first substrate inverting portion 67 and the second substrate inverting portion 68 change the state of the substrate 5 in Figure 13 (a) to the state of the substrate 5 in Figure 13 (d) , The substrate 5 is moved to draw a curve. That is, the substrate 5 is moved by a gentle motion. Therefore, the inversion of the substrate 5 in the present embodiment does not follow a linear movement, for example, a reverse movement in the direction along one side of the substrate 5. In addition, the operation is not an operation of continuing the two operations of the substrate reversal and the horizontal rotation of the substrate, nor does it simultaneously perform these two operations.

As shown in Figs. 13 (b) to 13 (d), the substrate 5 in Fig. 13 (a) has a short side on one side (left side in the figure) The short side is moved outward. More specifically, the rotation driving system of each axis of the robot shown in Fig. 4 is stopped, and a state in which each axis of the robot can be moved by the operator is set as a state in which the angles and displacements of the axes of the moved robots are detected by the sensor the angle and displacement of each axis of the robot for realizing the attitude of the substrate 5 and its attitude are taught and stored by the operator as described below. 13 (a), the substrate 5 is lifted from a horizontal plane where the substrate 5 is located, and the substrate 5 is moved in a tilted state so that the outer short side is higher than the inner short side do. The substrate 5 'indicates the position after the substrate 5 has moved. The curve 69 shows the locus of the substrate 5 connecting the vertexes corresponding to each other on the substrate 5 and the substrate 5 '. The first substrate inverting portion 67 and the second substrate inverting portion 68 move the substrate 5 so as to draw a curve. In other words, it can be said that the substrate moves along the trajectory of the curve. The curved line is an arc, and is not a straight line but a smooth locus. In addition to the above teaching, the angle and displacement data of each axis of the robot are generated so that the substrate moves in the reverse direction along the arc locus shown in Fig. 13, and stored and stored in the ROM of the control device in advance. The substrate may be reversely moved along the arc locus shown in Fig.

The substrate 5 is finally moved to the state shown in Fig. 13 (d) via the state shown in Figs. 13 (b) and 13 (c). The arrangement of the substrate 5 in (d) of Fig. 13 is such that the substrate 5 in Fig. 13 (a) is inverted and the short side of the substrate 5 is a long side along the carrying direction.

In addition, a process of changing the arrangement of the substrate 5 with reference to Fig. 14 will be described. Figs. 14 (a) to 14 (d) are plan views showing the process of reversing the substrate 5 by the reversing mechanism 65. Fig. The arrangement of the substrates 5 in Figs. 14 (a) to 14 (d) corresponds to the arrangement of the substrates 5 in Figs. 13 (a) to 13 (d).

14 is a plan view showing the rotation process of the substrate 5 in Fig. 14 shows the first substrate transport mechanism 61 and the second substrate transport mechanism 62 in addition to the reversing mechanism 65. As shown in Fig. 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. The first substrate transport mechanism 61 and the second substrate transport mechanism 62 are disposed in the same direction. That is, it does not have a complicated structure such as an L-shaped shape. Therefore, the bonding apparatus 60 according to the present invention is very simple to install and has excellent area efficiency.

First, as shown in Fig. 14 (a), the adsorption section 66 is adsorbed on the surface of the substrate 5, and the surface of the substrate 5 is held. Thereafter, the substrate 5 is moved along the locus of the curve 69 shown in Figs. 13 (a) to 13 (c) so as to arrange the substrate 5 in Fig. 14 (d). After the substrate 5 reaches the position shown in FIG. 13 (d), after the suction of the suction portion 66 is released to release the holding of the substrate 5, And is transported by the transport mechanism 62. Then, the inversion mechanism 65 returns to the position of (a) in Fig. 14, and inverts another substrate 5 which is sequentially transported by the same operation.

As a result, the substrate 5 is reversed, and (2) the long side along the transport direction of the first substrate transport mechanism 61 Or the short side is disposed along a direction orthogonal to the carrying direction. Therefore, the two states of the substrate 5 can be changed by one operation.

Since the two inversion mechanisms 65 produce two operations in this way, it is possible to invert the substrate 5 with a short tact time. That is, since the side of the substrate 5 is reversed and reversed by the single reversing mechanism 65, the length of the line in the bonding apparatus 60 is not constrained.

After the substrate 5 is reversed by the reversing mechanism 65 and the sides along the transport direction are changed, the nip roll 16 · 16a is used to adhere the polarizing film to the substrate 5 from the undersurface . As a result, the polarizing film can be bonded to the both surfaces of the substrate 5 from the lower surface at the same time by the joining apparatus 60, and the rectifying environment is not hindered.

In Fig. 14, the first substrate transport mechanism 61 and the second substrate transport mechanism 62 have a structure in which their transport directions are not arranged in a straight line but in an adjacent structure. This is because, when the substrate 5 of Fig. 14 (a) is compared with the substrate 5 of Fig. 14 (d), a straight line connecting a plurality of midpoints And is at an angle of 45 ° with respect to the conveying direction of the substrate 5 in the substrate conveying mechanism 61. As described above, the transport direction of the substrate 5 with respect to the first substrate transport mechanism 61 and the transport direction of the substrate 5 of the second substrate transport mechanism 62 are in the same direction, that is, parallel but not in the same straight line . The arrangement of the substrate 5 in Fig. 14 (d) is merely an example, and it is not necessary to arrange the substrate 5 strictly.

The reversing mechanism of the embodiment shown in Figs. 5 to 7 is provided with a reciprocating portion 671 capable of expanding and contracting in one direction as shown in the vertical direction in the figure with respect to the base portion 670, And a motor 6733 rotatably inserted in two support portions 6731 and 6732 disposed at the upper end of the rotation portion 672 and rotated within a range of 180 degrees by a motor 6733, A substrate reversing member 673 integrally provided on a rotary shaft 6734 as a substrate inverting unit integrally connected to a motor 6630 disposed on one end of the base member 660 of the substrate supporting apparatus 66, .

The rotating shaft 6734 driven by the motor 6733 constitutes an inversion axis of the substrate inverting portion 673 of the inverting mechanism and is fitted in the reciprocating portion 671 and rotated in the range of 90 degrees on the horizontal plane And the rotation axis of the rotation portion 672 is the axis of arrangement change.

The substrate reversing member 673 is moved from the state in which it extends in the width direction of the downstream end of the first substrate transport mechanism 61 shown in Figs. 5 and 7 by a control signal from the controller, 6, since the rotation portion 672 is rotated by 90 degrees in the counterclockwise direction at that time, when the rotation is rotated by 90 degrees, the rotation of the second substrate transport mechanism 62 The substrate 5 transported to the downstream end of the first substrate transport mechanism 61 is moved to the upstream end of the second substrate transport mechanism 62 by 90 degrees Thereby enabling conveyance.

17 is a plan view showing a modified example of the joining apparatus 60 using two reversing mechanisms 65. Fig. (2) the first substrate transport mechanism 61 is provided with the substrate placement section 61a; (3) the first substrate transport mechanism 61 and the second substrate transport mechanism 62 are arranged on a straight line. In addition, the first substrate transport mechanism 61 and the second substrate transport mechanism 62 are arranged in the same direction.

The bonding deviation inspection apparatus 72 is constituted by a camera and an image processing apparatus, and the camera is provided at a bonding position of a substrate 5 on which a polarizing film is bonded by a nip roll 16 · 16a. The substrate 5 is photographed by the camera and the photographed image information is processed to check whether or not the substrate 5 is deviated from the joining direction (the joining deviation inspection step, S3 in Fig. 19). As the bonding deviation inspection apparatus 72, a conventionally known bonding deviation inspection apparatus can be used.

The bonded foreign object automatic inspecting device 73 inspects presence or absence of foreign matter on the bonded substrate 5. The automatic foreign object inspection apparatus 73 is constituted by a camera and an image processing apparatus in the same manner as the joint deviation detection apparatus 72 and includes a substrate 5 after the polarizing film is bonded by the nip roll 16 · 16a, The above-described camera is provided in the second substrate transport mechanism (bonding apparatus 60). The substrate 5 is photographed by the camera and the photographed image information is processed to check presence or absence of foreign matter on the substrate 5 (bonded foreign matters inspection step, step S4).

The sorting and conveying device 74 judges whether or not there is a bond displacement or foreign matter based on the inspection results from the bonding deviation inspection device 72 and the automatic bonded product inspection device 73. The sorting and conveying device 74 receives an output signal based on the inspection result from the joint deviation inspection device 72 and the bonded matter automatic inspection device 73 to classify the bonded substrate 5 as a good product or a defective product It is good if there is. Therefore, conventionally known sorting and transporting systems can be used.
