Description

Polarizing film bonding apparatus and manufacturing system of liquid crystal display device having the same {POLARIZING FILM LAMINATION DEVICE AND LIQUID CRYSTAL DISPLAY MANUFACTURE SYSTEM PROVIDED WITH THE SAME}

The present invention relates to a polarizing film bonding apparatus for bonding a polarizing film to the upper and lower surfaces of a liquid crystal panel (hereinafter, simply referred to as a 'substrate' because it is an object of bonding the polarizing film to an upper surface and a lower surface thereof). A manufacturing system of a liquid crystal display device provided.

Background Art Conventionally, liquid crystal displays have been widely manufactured. It is common that the polarizing film is bonded to the board | substrate (liquid crystal panel) used for a liquid crystal display device in order to control transmission or interruption of light. The polarizing film is bonded so that the absorption axis may orthogonally cross.

As a method of bonding a polarizing film to a board | substrate, what is called a chip-to-panel system which cuts a polarizing film into the magnitude | size corresponding to a board | substrate, and joins is mentioned. However, in this system, since a polarizing film is bonded one by one with respect to a board | substrate, there exists a fault which is low in production efficiency. On the other hand, the so-called roll-to-panel system which supplies a polarizing film to a conveyor roll and joins to a board | substrate continuously as another system is mentioned. According to this method, joining is attained with high production efficiency.

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

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

However, the above conventional apparatus has the following problems.

First, when bonding a polarizing film with respect to a board | substrate, in order to avoid that a foreign material, such as dust, mixes in a bonding surface, it is common that work is performed in a clean room. In the clean room, air is rectified. It is because bonding of a polarizing film in the state which became rectified by the downflow with respect to a board | substrate is necessary in order to suppress the yield fall by a foreign material.

In this regard, the manufacturing system of Patent Document 1 is configured to bond a polarizing film from an upper surface and a lower surface to a substrate. However, when bonding is performed from the upper surface of the polarizing film, airflow (falling airflow) is hindered by the polarizing film, and the rectifying environment to the substrate is deteriorated. As an example in the case of bonding from the upper surface of a polarizing film, the velocity vector of the airflow in the upper bonding type | mold manufacturing system is shown to FIG. 9 (a) and FIG. 9 (b). In FIG. 9, area | region A is the area | region in which the unwinding part etc. which unwind a polarizing film are provided, area | region B mainly winds the area | region through which a polarizing film passes, and area | region C winds up the peeling film removed from the polarizing film. It is an area in which a winding section or the like is installed.

In addition, clean air is supplied from the HEPA (High Efficiency Particulate Air) filter 40. In addition, in FIG. 9A, since a grating 41 through which clean air can pass is provided, the air flow can move in the vertical direction through the grating 41. On the other hand, in FIG. 9B, since the grating 41 is not provided, the air flow contacts the bottom of the bottom of FIG. 9B, and then moves along the bottom.

In FIGS. 9A and 9B, regions A to C are disposed in the 2F (two layers) portion, and clean air from the HEPA filter 40 is disturbed by the polarizing film. Therefore, airflow in a direction perpendicular to the substrate passing through the 2F portion is unlikely to occur. On the other hand, the airflow vector in the horizontal direction is in a large (high density of vector). In other words, it can be said that the rectifying environment is in a deteriorated state.

EMBODIMENT OF THE INVENTION Although one Embodiment of this invention is described based on FIGS. 1-8, it is as follows, but this invention is not limited to this. First, the structure of the manufacturing system (manufacturing system of the liquid crystal display device) concerning this invention is demonstrated below. The manufacturing system includes the bonding apparatus which concerns on this invention.

1 is a cross-sectional view showing a manufacturing system. As shown in the figure, the manufacturing system 100 has a two-stage structure, the 1F (first layer) portion is the film conveyance mechanism 50, and the 2F (two layers) portion is the substrate conveyance mechanism (first substrate ( Liquid crystal panel) and a bonding apparatus 60 including a second mechanism (liquid crystal panel) transfer mechanism.

<Film conveyance mechanism>

First, the film conveyance mechanism 50 is demonstrated. The film conveyance mechanism 50 unwinds (unwinds) a polarizing film (polarizing plate), conveys to nip rollers 6-6a and 16-16a, and plays a role which winds up the peeling film which became unnecessary. On the other hand, the bonding apparatus 60 plays a role of bonding the polarizing film unwound by the film conveyance mechanism 50 with respect to the liquid crystal panel (substrate) 5.

The film conveyance mechanism 50 is equipped with the 1st film conveyance mechanism 51 and the 2nd film conveyance mechanism 52. The 1st film conveyance mechanism 51 conveys a polarizing film to the nip roller 6-6a which bonds a polarizing film to the lower surface of the board | substrate 5 for the first time. On the other hand, the 2nd film conveyance mechanism 52 conveys a polarizing film on the lower surface of the inverted board | substrate 5.

The 1st film conveyance mechanism 51 is the 1st unwinding part 1, the 2nd unwinding part 1a, the 1st winding-up part 2, the 2nd winding-up part 2a, the half cutter 3, the knife edge (4) and the fault film winding rollers 7-7a. The disk of a polarizing film is provided in the 1st unwinding part 1, and a polarizing film is unwound. As the polarizing film, a known polarizing film may be used. Specifically, the polyvinyl alcohol film is dyed with iodine or the like, and a film or the like stretched in the uniaxial direction can be used. Although it does not specifically limit as thickness of the said polarizing film, The polarizing film of 5 micrometers or more and 400 micrometers or less can be used preferably.

In the disk of the said polarizing film, the direction of an absorption axis is located in a flow direction (MD direction). The adhesive layer is protected by the peeling film of the said polarizing film. As said peeling film (also called a "protective film" or a "separator"), a polyester film, a polyethylene terephthalate film, etc. 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, when the remaining amount of the original disk of the first unwinding portion 1 becomes small, the second unwinding portion 1a is provided. It is possible to connect the provided disk to the disk of the 1st unwinding part 1. As a result, it is possible to continue working without stopping unwinding of a polarizing film. By this structure, production efficiency can be improved. In addition, what is necessary is just to be each provided in multiple numbers, and may be provided three or more of the said unwinding part and the winding-up part.

The half cutter (cutting part 3) half-cuts the polarizing film (film laminated body comprised from a polarizing film, an adhesive layer, and a peeling film) protected by the peeling film, and cut | disconnects a polarizing film and an adhesive layer. As the half cutter 3, a well-known member may be used. Specifically, a blade, a laser cutter, etc. are 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 portion 4).

The adhesive layer is apply | coated between a polarizing film and a peeling film, and after a peeling film is removed, an adhesive layer remains on the polarizing film side. It does not specifically limit as said adhesive layer, Adhesive layers, such as an acryl type, an epoch clock, a polyurethane type, are mentioned. Although the thickness in particular of an adhesive layer is not restrict | limited, Usually, it is 5-40 micrometers.

On the other hand, the 2nd film conveyance mechanism 52 is the same structure as the 1st film conveyance mechanism 51, and the 1st unwinding part 11, the 2nd unwinding part 11a, the 1st winding-up part 12, the 1st The two winding parts 12a, the half cutter 13, the knife edge 14, and the defect film winding rollers 17-17a are provided. About the member which attached the same member name, the same effect as the member in the 1st film conveyance mechanism 51 is shown.

As a preferable embodiment, the manufacturing system 100 includes a cleaning unit 71. The cleaning part 71 wash | cleans the board | substrate 5 before bonding a polarizing film to the lower surface of the board | substrate 5 with the nip roller 6-6a. As the cleaning part 71, a well-known cleaning part comprised of a nozzle, a brush, etc. which spray a cleaning liquid may be used. By cleaning the board | substrate 5 just before joining with the washing | cleaning part 71, joining can be performed in the state in which the foreign material of the board | substrate 5 is few.

Next, the knife edge 4 is demonstrated using FIG. 2 is a cross-sectional view showing a peripheral portion of the nip rollers 6-6a in the manufacturing system 100.

FIG. 2 has shown the situation that the board | substrate 5 is conveyed from the left direction, and the polarizing film 5a which has an adhesive layer (not shown, the same is the same after this) from the lower left direction is conveyed. The polarizing film 5a is equipped with the peeling film 5b, the polarizing film 5a and the adhesive layer are cut | disconnected by the half cutter 3, and the peeling film 5b is not cut | disconnected (half cut).

The knife edge 4 is provided in the peeling film 5b side. The knife edge 4 is an edge-shaped member for peeling off the peeling film 5b, and the polarizing film 5a and the peeling film 5b with low adhesive force peel off along the knife edge 4.

Thereafter, the release film 5b is wound around the first winding portion 2 of FIG. 1. In addition, it is also possible to use the structure which winds up a peeling film using an adhesive roller instead of the knife edge. 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-up part.

Next, the bonding apparatus 60 is demonstrated. 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, rectification of the downdraft is performed. Thereby, the conveyance and bonding of the board | substrate 5 can be performed in a stable state.

<Bonding device>

The bonding apparatus 60 is provided in the upper part of the film conveyance mechanism 50. As shown in FIG. Thereby, space saving of the manufacturing system 100 can be aimed at. Although not shown, the bonding apparatus 60 is provided with the board | substrate conveyance mechanism provided with a conveyor roll, and by this, the board | substrate 5 is conveyed in a conveyance direction (the 1st board | substrate conveyance mechanism 61 mentioned later in FIG. 5). 2nd board | substrate conveyance mechanism 62 corresponds to a board | substrate conveyance mechanism).

In the manufacturing system 100, the board | substrate 5 is conveyed from the left side, and it is conveyed to the upper part of the 2nd film conveyance mechanism 52 from the right side of a figure, ie, the upper part of the 1st film conveyance mechanism 51 in the figure. . Between the film conveyance mechanism 50 and the bonding apparatus 60, the nip roller 6-6a, 1st bonding part which is a bonding part, and the nip roller 16-16a, 2nd bonding part are respectively provided. Nip rollers 6-6a and 16-16a are members which serve to bond the polarizing film from which the peeling film was removed to the lower surface of the board | substrate 5. In addition, since the polarizing film is bonded by the lower surface to both surfaces of the board | substrate 5, after bonding by the nip roller 6-6a, the board | substrate 5 is inverted by the inversion mechanism 65. As shown in FIG. The inversion mechanism 65 is mentioned later.

The polarizing film conveyed by the nip roller 6-6a is bonded by the lower surface of the board | substrate 5 via an adhesive layer. As the nip rollers 6-6a, well-known structures, such as a press roller and a press roller, can be employ | adopted, respectively. Moreover, what is necessary is just to adjust the pressure and temperature at the time of joining in the nip roller 6-6a suitably. The same applies to the configuration of the nip rollers 16 to 16a. In addition, although not shown, in the manufacturing system 100, as a preferable structure, the fault display (mark) detection part is provided between the 1st unwinding part 1 to the half cutter, and the structure in which the polarizing film which has a fault is detected is detected. It is.

In addition, the said fault display detects at the time of the raw material creation of a polarizing film, and provides a fault display. Or it adheres to a polarizing film by the fault display provision part provided in the 1st unwinding part 11 or the 2nd unwinding part 11a side rather than a fault display detection part. A fault display provision part is comprised by a camera, an image processing apparatus, and a fault display formation part. First, imaging | photography of a polarizing film is performed by the said camera, and the presence or absence of a fault can be examined by processing the said imaging | photography information. As said fault, a foreign material, such as dust, a fish eye etc. are mentioned specifically ,. When a fault is detected, a fault mark is formed in a polarizing film by a fault mark formation part. As a fault display, marks, such as ink, are used.

In addition, the bonding avoidance part which is not shown in figure discriminates the said mark with a camera, and transmits a stop signal to the bonding apparatus 60, and stops conveyance of the board | substrate 5. Then, the polarizing film in which the defect was detected is wound up by the defect film winding roller (recovery part, 7-7a), without bonding by the nip roller 6-6a. Thereby, joining with the board | substrate 5 and the polarizing film which has a fault can be avoided. If the said series of structures is provided, since the bonding between the polarizing film which has a fault and the board | substrate 5 can be avoided, productivity can be improved and it is preferable. As a fault detection part and a junction avoidance part, a well-known inspection sensor can be used suitably.

As shown in FIG. 1, after the board | substrate 5 turns into the inverted state by the inversion mechanism 65, the board | substrate 5 is conveyed by the nip rollers 16-16a. And the polarizing film is bonded by the lower surface of the board | substrate 5. As a result, a polarizing film is bonded to both surfaces of the board | substrate 5, and two polarizing films are bonded to both surfaces of the board | substrate 5 by the mutually different absorption axis. Thereafter, as necessary, inspection is performed on both surfaces of the substrate 5 for bonding misalignment. This test | inspection can employ | adopt the structure comprised by the test part etc. which comprise a camera normally.

Thus, in the manufacturing system 100, when bonding a polarizing film to the board | substrate 5, it becomes a structure which bonds from the lower surface of the board | substrate 5, and does not disturb the rectifying environment to the board | substrate 5, either. . For this reason, foreign material mixing to the joining surface of the board | substrate 5 can also be prevented, and a more accurate joining becomes possible.

3 (a) and 3 (b) show the velocity vectors of the airflow in the bottom junction type manufacturing system according to the present invention. The region A in FIGS. 3A and 3B is a region where the unwinding portion is provided, the region B is a region mainly through which the polarizing film passes, and the region C is a region where the winding portion or the like is provided. In addition, clean air is supplied from the HEPA filter 40. In addition, since the grating 41 which clean air can pass is provided in FIG.3 (a), it is possible to move an airflow in a vertical direction via the grating 41. FIG. On the other hand, in FIG. 3B, since the grating 41 is not provided, the air flow moves along the bottom after contacting the bottom.

Since the manufacturing system shown to Fig.3 (a) and (b) is a bottom bonding type, as shown to Fig.9 (a) and (b), the airflow from the HEPA filter 40 is interrupted by a polarizing film. It doesn't work. For this reason, the direction of an airflow vector becomes a direction toward a board | substrate almost, and it can be said that the preferable rectification environment is implement | achieved in a clean room. In FIG. 3A, the grating 41 is provided, and in FIG. 3B, the grating 41 is provided, but the same preferred state is shown in both figures. In addition, although the board | substrate conveyance mechanism is formed horizontally in FIG. 3 and FIG. 9, it is not provided as a series structure. For this reason, the airflow can pass between the substrate transfer mechanisms. After the board | substrate is hold | maintained by the inversion mechanism mentioned later, it is a structure which can transfer between board | substrate conveyance mechanisms.

In addition, in the manufacturing system 100, the board | substrate 5 is first conveyed by a long side width (long side orthogonal to a conveyance direction), and then conveyed by a short side width (short side orthogonal to a conveyance direction). It is made up.

<Inversion mechanism>

The inversion mechanism 65 changes the arrangement | positioning to the board | substrate 5 along the short side or long side conveyance direction, and is a state along the long side or short side conveyance direction, and inverted. 4A to 4C are perspective views illustrating a process of inverting the substrate 5 by the inversion mechanism 65.

FIG.4 (a) shows the state which adsorb | sucks the board | substrate 5 conveyed by the 1st board | substrate conveyance mechanism. FIG. 4B shows a process of moving the substrate 5, and FIG. 4C shows a state in which the substrate 5 is inverted by the second substrate inversion mechanism. In addition, although the 1st board | substrate conveyance mechanism and the 2nd board | substrate conveyance mechanism are abbreviate | omitted in FIG. 4 for convenience of illustration, it mentions later using FIG.

As shown to Fig.4 (a), the inversion mechanism 65 is equipped with the adsorption part 66, the board | substrate inversion part 67, and the lifting part 68. As shown in FIG. The adsorption part 66 is a member which adsorbs on the surface of the board | substrate 5. By the adsorption part 66, the surface of the board | substrate 5 is hold | maintained in the adsorption part 66. As shown in FIG. As the adsorption part 66, a well-known adsorption part can be used, for example, the air suction system adsorption part can be used.

The substrate inverting portion 67 is connected to the adsorption portion 66 and is formed to connect the adsorption portion 66 and the lifting portion 68. The substrate inverting portion 67 inverts the substrate 5 by rotating around the inversion axis M. In FIG. 4A, the lifting portion 68 side of the substrate inversion portion 67 faces the substrate 5 and extends in a direction perpendicular to the inversion axis M. As shown in FIG. In addition, the adsorption | suction part 66 side of the board | substrate inversion part 67 passes along the center of the board | substrate 5 in a 1st board | substrate conveyance mechanism, and follows the straight line parallel to the long side (conveying direction) of the board | substrate 5; It is a shape bent about 40 degrees. The shape of the board | substrate inversion part 67 shown to Fig.4 (a) is only an example, It is not limited to the shape. As another shape, for example, instead of bending like the substrate inverting part 67, it can also be set as the shape curved to the adsorption | suction part 66 side from the lifting-up part 68 side. Moreover, you may employ | adopt the structure which has a some moving part like a robot arm.

The substrate inverting portion 67 has a configuration in which the rotatable movable portion is provided in the lifting portion 68. The movable portion is arranged along the inverting shaft M, and the substrate inverting portion 67 is rotatable along the inverting shaft M. As shown in FIG.

The inversion axis M passes through the center of the board | substrate 5 in the 1st board | substrate conveyance mechanism, and has the straight line which has the inclination of 45 degrees with respect to the straight line perpendicular | vertical to the conveyance direction of the board | substrate 5 with a reference | standard. It is in-plane perpendicular to the board | substrate 5 (refer FIG. 5 (a)), and (2) is located in the position (refer FIG. 4 (a)) parallel to the board | substrate 5, and . The inverted shaft M is located in the in-plane, and may be moved in the vertical direction with respect to the substrate 5.

Although the board | substrate inversion part 67 is comprised in the structure which rotates along the inversion axis M via the movable part, what is necessary is just to be able to rotate along the inversion axis M, and it is not limited to the said structure. For example, the substrate inverting portion 67 has a rotating shaft structure. The axis of the rotating shaft structure rotates along the inverting shaft M, and the entire substrate inverting portion 67 can be rotated. The rotational movement of the substrate inverting portion 67 is made by, for example, a driving device such as a motor (not shown).

The board | substrate inversion part 67 can invert the board | substrate 5 by one rotation which makes the inversion axis M the axis. The inversion indicates that the substrate 5 is rotated to the opposite surface, that is, the surface of the substrate 5 is disposed so as to be the back surface.

The lifting portion 68 has an arm shape having a bent portion, and the substrate inverting portion 67 can be raised by reducing the angle of the arm. On the other hand, the substrate inverting portion 67 can be lowered by increasing the angle of the arm. The adsorption part 66 is arrange | positioned above the board | substrate 5 so that the board | substrate 5 may not contact with the board | substrate 5 when it is not conveyed. And when the board | substrate 5 is conveyed, since the board | substrate inversion part 67 descends by the lifting-up part 68, and the adsorption part 66 also descends, the adsorption part 66 can adsorb | suck the board | substrate 5. have. After the substrate 5 is inverted, the adsorption of the adsorption portion 66 is released. However, after the release, the lifting unit 68 moves the substrate inversion portion 67 so that the adsorption portion 66 moves the substrate 5. Away from

The operation of the inversion mechanism 65 will be described with reference to FIGS. 4A to 4C. First, in FIG. 4A, the case where the short side of the board | substrate 5 follows the conveyance direction is shown. After the surface of the board | substrate 5 is adsorbed by the adsorption part 66, the board | substrate inversion part 67 rotates along the inversion axis M. As shown in FIG. In the same figure, although the adsorbing part 66 adsorb | sucks the vicinity of the center of the board | substrate 5, what is necessary is just to fix so that the board | substrate 5 may not fall at the time of rotation, and an adsorption point is not specifically limited. Moreover, the adsorption point is not limited to four places, of course.

Next, from the state of FIG. 4A, the substrate inverting portion 67 rotates along the inversion axis M toward the substrate surface side. 4B illustrates a state in which the substrate inverting portion 67 is rotated by 90 ° with respect to the substrate 5 (in the first substrate transfer mechanism) in FIG. 4A. Via the state of FIG. 4B, the substrate inverting portion 67 continues to rotate, and the substrate 5 is inverted as shown in FIG. 4C.

In this manner, by one rotational operation of the inversion mechanism 65, the directions of the short and long sides of the substrate 5 can be changed and reversed. That is, the board | substrate 5 can be reversed with a short tact time, without involving a complicated rotation operation. As a result, the bonding of the polarizing film to the substrate 5 including the inversion can be performed with a short tact time.

In addition, in FIG. 4, in order to move the board | substrate 5 further to a conveyance direction, the board | substrate inversion part 67 is provided in the conveyance direction side with respect to the board | substrate 5 of FIG. Thereby, like FIG.4 (c), it can invert in the state which moved the board | substrate 5 in a 2nd board | substrate conveyance mechanism further in the conveyance direction. This makes it possible to shorten the tact time associated with double-sided bonding including inversion.

FIG. 5 is a plan view illustrating a rotation process of the substrate 5 corresponding to FIG. 4. In FIG. 5, the first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 are illustrated. Although not shown, the 1st board | substrate conveyance mechanism 61 and the 2nd board | substrate conveyance mechanism 62 are equipped with the conveyor roller. The first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 carry the substrate 5 in the same direction. For this reason, the 1st board | substrate conveyance mechanism 61 and the 2nd board | substrate conveyance mechanism 62 become linear shape along a conveyance direction. That is, it does not have complicated structures, such as L-shape. Therefore, the bonding apparatus 60 which concerns on this invention is a structure which is very easy to install and is excellent in area efficiency.

Although demonstrated in FIG. 4, the surface of the board | substrate 5 is hold | maintained by the adsorption | suction part 66 as shown to FIG. 5 (a). Next, as shown in FIG. 5B, the substrate inverting portion 67 is rotated 90 degrees along the direction of the inversion axis M, and the substrate 5 is in a vertical state. Finally, as shown in FIG. 5C, the substrate inverting portion 67 further rotates the inversion axis M along the direction, thereby inverting the substrate 5. When the substrate 5 is inverted, the substrate 5 is disposed on a conveyor roller (not shown), and the substrate inverting portion 67 does not contact the conveyor roller. For this reason, the inversion mechanism 65 is located under the board | substrate 5.

Thereafter, the adsorption of the adsorption portion 66 is released, so that the holding of the substrate 5 is released, and the substrate 5 is conveyed by the second substrate transfer mechanism 62. And the inversion mechanism 65 returns to the position of FIG.5 (a), and inverts the other board | substrate 5 conveyed one by one in the same operation | movement.

Thus, according to the inversion mechanism 65, after the adsorption | suction by the adsorption | suction part 66, the board | substrate 5 is inverted by one operation | movement, and the long side and short side with respect to a conveyance direction are changed. You can change it. Before the inversion operation, a polarizing film is bonded to the lower surface of the substrate 5, and after performing the inversion operation, the polarizing film can be further bonded to the lower surface of the inverted substrate 5. (1) Thus, a polarizing film can be bonded to both surfaces of the board | substrate 5 from the lower surface, (2) The said inversion operation is a simple rotation operation, and also a tact time is short for one operation. Therefore, joining with short tact time can be realized without disturbing the rectifying environment.

In addition, although the inversion | operation operation | movement of the board | substrate inversion part 67 is one operation | movement, even if it included the operation | movement which raises and lowers the board | substrate 5, and / or the position of adjusting the position of the board | substrate inversion part 67 is included. And the operation of the inversion mechanism 65 according to the present invention.

In FIG. 5, the first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 carry the substrate 5 in the same direction, and have a structure adjacent to each other. Since the short side and long side with respect to the conveyance direction of the board | substrate 5 are changed by the board | substrate inversion part 67 as this (c) of FIG. 5, the 2nd board | substrate conveyance which conveys the board | substrate 5 after inversion | conversion is carried out. It is because the conveyance directions in the mechanism 62 and the 1st board | substrate conveyance mechanism 61 are not located in a line with each other, and a shift generate | occur | produces. In addition, even if the 1st board | substrate conveyance mechanism 61 and the 2nd board | substrate conveyance mechanism 62 do not necessarily need to adjoin, even if the space | interval is provided in the 1st board | substrate conveyance mechanism 61 and the 2nd board | substrate conveyance mechanism 62. good.

As described above in FIG. 4, in order to move the substrate 5 further in the conveying direction, the substrate inverting portion 67 is provided on the conveying direction side with respect to the substrate 5 before inversion. However, when there are restrictions such as the arrangement of the inversion mechanism 65, the inversion mechanism 65 may be arranged as shown in FIG. 5D. In this case, although the board | substrate 5 cannot be moved further in a conveyance direction, it can respond to the limitation, such as arrangement | positioning of the inversion mechanism 65.

6 is a plan view illustrating a modification of the bonding apparatus 60. As a change point in this modification, (1) two inversion mechanisms 65a and 65b are provided, and (2) two substrate placing portions 61a are provided on both sides of the first substrate transfer mechanism 61. (3) The first substrate transfer mechanism 61 and the second substrate transfer mechanism 62 are arranged in a straight line. In addition, the point by which the board | substrate 5 is conveyed in the same direction by the 1st board | substrate conveyance mechanism 61 and the 2nd board | substrate conveyance mechanism 62 is the same.

The board | substrate mounting part 61a and the inversion mechanism 65a, 65b are the edges of the 1st board | substrate conveyance mechanism 61 of the said end at the edge part of the 2nd board | substrate conveyance mechanism 62 side in the 1st board | substrate conveyance mechanism 61. As shown in FIG. It is provided along the bidirectional which is horizontal with respect to a conveyance direction. The inversion mechanisms 65a and 65b are the same as the structure described with reference to FIGS. 4 and 5. Moreover, the said conveyance means which conveys the board | substrate 5 to the board | substrate mounting part 61a is provided in the said edge area 61b. Specifically, a conveyor roller is mentioned, for example.

The substrate (liquid crystal panel) placing portion 61a is where the substrate (liquid crystal panel 5) is disposed by the adsorption portion 66. According to this modification, the board | substrate 5 conveyed by the 1st board | substrate conveyance mechanism 61 is conveyed alternately to two board | substrate mounting parts 61a. Since one inversion mechanism 65a, 65b is provided with respect to one board | substrate mounting part 61a, the board | substrate 5 conveyed to the board | substrate mounting part 61a is one by the inversion mechanism 65a, 65b. Inverted by the action.

In this modification, the two board | substrate mounting parts 61a are each provided along the horizontal bidirectional direction of the 1st board | substrate conveyance mechanism 61, and the inverted board | substrate 5 of the 1st board | substrate conveyance mechanism 61 is carried out. It is arrange | positioned along a conveyance direction. Therefore, it is possible to arrange | position the 1st board | substrate conveyance mechanism 61 and the 2nd board | substrate conveyance mechanism 62 in a straight line.

According to this modification, since (1) two inversion mechanisms 65a and 65b are provided, the substrate 5 can be processed twice per unit time. As a result, since many substrates 5 can be inverted per unit time, the tact time is shortened. (2) Moreover, since the 1st board | substrate conveyance mechanism 61 and the 2nd board | substrate conveyance mechanism 62 are arrange | positioned in a straight line, the bonding apparatus of the structure which was more excellent in area efficiency can be provided. Since the area efficiency is required especially in a clean room, the said bonding apparatus is very preferable.
