The determination method of the bonding position (relative bonding position) of the sheet piece FXm with respect to liquid crystal panel P is as follows, for example.

First, as shown in FIG. 18A, a plurality of inspection points CP are set in the width direction of the optical member sheet FX, and the direction of the optical axis of the optical member sheet FX is detected at each inspection point CP. The timing for detecting the optical axis may be at the time of manufacture of the far-end roll R1, or may be until it unwinds and half-cuts the optical member sheet | seat FX from the far-end roll R1. The data in the optical axis direction of the optical member sheet FX is stored in a storage device (not shown) in association with the position of the optical member sheet FX (position in the longitudinal direction and position in the width direction of the optical member sheet FX).

The control apparatus 25 acquires the data (inspection data of the in-plane distribution of an optical axis) of each inspection point CP from a memory | storage device (not shown), and the optical member sheet | seat FX (section | section) in which the sheet piece FXm is cut out. The direction of the average optical axis of the area | region partitioned by the granular line CL is detected.

For example, as shown in FIG. 18B, the angle (deviation angle) between the direction of the optical axis and the edge line EL of the optical member sheet FX is detected for each inspection point CP, and the largest angle (maximum displacement angle) of the displacement angles is detected. When () is set to θmax and the smallest angle (minimum deviation angle) is θ min, the average value θ mid (= (θ max + θ min) / 2) of the maximum deviation angle θ max and the minimum deviation angle θ min is detected as the average deviation angle. The direction of forming the average shift angle θmid with respect to the edge line EL of the optical member sheet FX is detected as the direction of the average optical axis of the optical member sheet FX. In addition, the said shift | offset | difference angle is computed, for example, making the left rotation direction positive with respect to the edge line EL of the optical member sheet | seat FX, and making the right rotation direction negative.

And the bonding position of the sheet piece FXm with respect to liquid crystal panel P so that the direction of the average optical axis of the optical member sheet FX detected by the said method may form a desired angle with respect to the long side or short side of the display area P4 of liquid crystal panel P. (Relative joining position) is determined. For example, when the direction of the optical axis of the optical member F1X is set to the direction which makes 90 degrees with respect to the long side or short side of the display area P4 according to a design specification, the direction of the average optical axis of the optical member sheet | seat FX will be Sheet piece FXm is bonded by liquid crystal panel P so that it may become 90 degrees with respect to the long side or short side of display area P4.

The cutting devices 51 and 52 mentioned above detect the outer periphery of the display area P4 of liquid crystal panel P with a detection means, such as a camera, and endlessly follow the outer periphery of the display area P4 with the sheet piece FXm bonded by liquid crystal panel P. Cut into phases. The outer periphery of display area P4 is detected by imaging the edge part of liquid crystal panel P, the alignment mark provided in liquid crystal panel P, or the outermost edge of the black matrix provided in display area P4. Outside the display area P4, a frame portion G (see FIG. 3) having a predetermined width is disposed to arrange a sealant for bonding the first and second substrates of the liquid crystal panel P, and within the width of the frame portion G. Cutting of the sheet piece FXm by the cutting devices 51 and 52 is performed.

In addition, the detection method of the average optical axis direction in the optical member sheet | seat FX surface is not limited to the said method. For example, one or a plurality of inspection points CP are selected from the plurality of inspection points CP (see FIG. 18A) set in the width direction of the optical member sheet FX, and for each selected inspection point CP, the direction of the optical axis and the optical member sheet FX The angle (deviation angle) which forms the edge line EL is detected. Then, the average value of the deviation angles in the optical axis direction of the selected one or the plurality of inspection points CP is detected as the average deviation angle, and the direction of forming the average deviation angle with respect to the edge line EL of the optical member sheet FX is determined by the optical member sheet FX. It can also detect as an average optical axis direction.

As described above, the film bonding system 2 in this embodiment is a thing formed by bonding the optical member F1X to liquid crystal panel P, and the length of either side of the long side and short side of the display area P4 of liquid crystal panel P is carried out. While unwinding the wider band-shaped optical member sheet FX from the roll roll R1, the optical member sheet FX is cut to a length longer than the length of the other side of either the long side or the short side of the display area P4, and the sheet piece FXm. After that, the bonding apparatuses 13, 15, and 18 which bond the sheet piece FXm to the liquid crystal panel P, and the excess part arrange | positioned on the outer side of the part which opposes the display area P4 from the sheet piece FXm bonded to the liquid crystal panel P are cut off. And cutting devices 51, 52 for forming optical member F1X having a size corresponding to display area P4, and bonding apparatuses 13, 15, and 18 separate optical member sheet FX from fabric roll R1 and separator sheet F3. On the basis of the judgment result of the unwinding part 31a unwinding with a, the judgment part which judges whether the fault is contained in the optical member sheet | seat FX unwound by the unwinding part 31a, The cutting apparatus 31b which cuts the member sheet | seat FX leaving separator sheet F3a, and forms the non-defective sheet piece which does not contain a fault, or the defective sheet piece containing a defect, and the non-defective sheet piece or the defective sheet piece from separator sheet F3a The adsorption stage 41 which has the knife edge 31c which peels, the adsorption surface 41a which adsorbs and hold | maintains liquid crystal panel P, and does not overlap with the adsorption stage 41 from the normal direction of the adsorption surface 41a is seen. The separator sheet F3a is held at the position, holds the recovery stage 42 for collecting the defective sheet piece, and the good sheet sheet peeled off from the separator sheet F3a, and is bonded to the liquid crystal panel P. The bonding head 32 which hold | maintains the defective article sheet peeled from the past, and bonds to the collection | recovery stage 42, and the bonding head 32 collect | recovers between the knife edge 31c and liquid crystal panel P, or the knife edge 31c. It includes a moving device 70 for moving between the stage (42).

According to this configuration, the defective article sheet can be discarded in the recovery stage 42.

Therefore, even if it does not use a removal film etc. separate from a separator, a defective sheet piece can be removed. Moreover, compared with the structure which collect | recovers the film for removal separate from a separator with a defective sheet piece, a film for removal can be omitted and the cost required for the film for removal can be omitted. Moreover, since the defective article sheet piece can be collect | recovered using the collection | recovery stage 42, it is not necessary to provide the apparatus which collect | recovers the film for removal separately, and can simplify a device structure. In addition, a non-defective sheet piece can be bonded to liquid crystal panel P while removing the defective article sheet piece. Therefore, a defective sheet piece can be collect | recovered effectively.

In addition, in the film bonding system 2, it is possible to provide optical member F1X to the boundary of display area P4 with high precision, and narrows the frame part G (refer FIG. 3) of the display area P4 outer side, and enlarges a display area. The device can be miniaturized.

In addition, in the film bonding system 2, the 1st cutting device 51 and the 2nd cutting device 52 are a laser cutter, and the 1st cutting device 51 and the 2nd cutting device 52 are the same laser output. It is connected to the apparatus 53, and the laser output from the laser output apparatus 53 may be branched and supplied to the 1st cutting apparatus 51 and the 2nd cutting apparatus 52. FIG. In this case, compared with the case where a different laser output device is connected to each of the 1st cutting device 51 and the 2nd cutting device 52, the production system of an optical display device can be miniaturized.

In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention, including a component structure, a structure, a shape, size, number, arrangement | positioning, etc.

In addition, the magnitude | size of the surplus part (size of the part which protrudes outward of liquid crystal panel P) of the sheet piece FXm is suitably set according to the size of liquid crystal panel P. FIG. For example, when sheet piece FXm is applied to liquid crystal panel P of the medium size of 5 inches-10 inches, the space | interval between one side of sheet piece FXm and one side of liquid crystal panel P in each side of sheet piece FXm. Is set to a length in the range of 2 mm to 5 mm.

Hereinafter, the film bonding system which concerns on 5th Embodiment of this invention is demonstrated with reference to FIGS. 19-21. In addition, in FIG.19-21, illustration of the 2nd sheet piece F2m is abbreviate | omitted for convenience. In this embodiment, the same code | symbol is attached | subjected to the structure same as the film bonding system 2 demonstrated in the said embodiment, and detailed description is abbreviate | omitted. In addition, the optical member F1X in this embodiment is formed by cut | disconnecting the outer excess part of the bonding surface from the sheet piece FXm bonded by liquid crystal panel P. FIG.

The film bonding system which concerns on this embodiment is equipped with the 1st detection apparatus 91 (refer FIG. 20). The 1st detection apparatus 91 is provided in the panel conveyance downstream rather than the 2nd bonding position 11d. The 1st detection apparatus 91 detects the edge of the bonding surface (henceforth a 1st bonding surface) of liquid crystal panel P and the 1st sheet piece F1m.

As shown, for example in FIG. 19, the 1st detection apparatus 91 is the edge ED (bonding) of the 1st bonding surface SA1 in four test | inspection area | region CA provided on the conveyance path | route of the upstream conveyor 6. Outer periphery of the surface) is detected. Each test | inspection area | region CA is arrange | positioned in the position corresponding to four corner | angular parts of 1st bonding surface SA1 which has a rectangular shape. The edge ED is detected for every liquid crystal panel P conveyed along a line top. Data of the end edge ED detected by the first detection device 91 is stored in the storage device 24 (see FIG. 16).

In addition, the arrangement position of test | inspection area | region CA is not limited to this. For example, each test | inspection area | region CA may be arrange | positioned in the position corresponding to each edge part (for example, center part of each edge | side) of 1st bonding surface SA1.

20 is a schematic diagram of the first detection device 91.

It is preferable to set so that the shift | offset | difference at the time of division | dividing, burr, etc. may not enter. For example, when the end surface of the 2nd board | substrate P2 is shifted outward rather than the end surface of the 1st board | substrate P1, the inclination-angle (theta) of the imaging device 93 is the 2nd board | substrate P2 in the imaging visual field of the imaging device 93. Set the edge of the edge so that it does not retract.

The inclination angle θ of the imaging device 93 is suitably set to the distance H (hereinafter referred to as the height H of the imaging device 93) between the first bonding surface SA1 and the center of the imaging surface 93a of the imaging device 93.

In addition, the illumination light source 94 and the imaging device 93 may be arrange | positioned so that the movement along the edge ED of 1st bonding surface SA1 may be carried out. In this case, the illumination light source 94 and the imaging device 93 should just be provided 1 each, respectively. Moreover, by this, the illumination light source 94 and the imaging device 93 can be moved to the position which is easy to image the edge ED of 1st bonding surface SA1.

The cut position of the 1st sheet piece F1m is adjusted based on the detection result of the edge ED of 1st bonding surface SA1. The control apparatus 25 (refer FIG. 16) acquires the data of the edge ED of 1st bonding surface SA1 memorize | stored in the memory | storage device 24 (refer FIG. 16), and the 1st optical member F11 is the outer side of liquid crystal panel P. FIG. The cut position of the 1st sheet piece F1m is determined so that it may become a magnitude | size which does not protrude to (outside of 1st bonding surface SA1). The first cutting device 51 cuts the first sheet piece F1m at the cut position determined by the control device 25.

Here, "the magnitude | size corresponding to 1st bonding surface SA1" is a magnitude | size below the magnitude | size of the display area P4, the magnitude | size of the liquid crystal panel P outline shape (contour shape seen from planar view), and a functional part, such as an electrical component installation part, here. Indicates the size of the area avoided.

By bonding the first sheet piece F1m and the second sheet piece F2m to the liquid crystal panel P, the cuts are cut at the same time so that the positional shift between the first optical member F11 and the second optical member F12 is eliminated, and the outer peripheral shape of the first bonding surface SA1 is eliminated. A fitting first optical member F11 and second optical member F12 are obtained. Moreover, the cutting process of 1st sheet piece F1m and 2nd sheet piece F2m is also simplified.

By the 1st cutting device 51, the excess part of 1st sheet piece F1m and 2nd sheet piece F2m is cut off from 2nd optical member bonding body PA2, and the 1st optical member F11 and the front and back surface of liquid crystal panel P are carried out. 3rd optical member bonding body PA3 formed by bonding 2nd optical member F12 is formed. At this time, 3rd optical member bonding body PA3 and the part (each optical member F11, F12) corresponding to 1st bonding surface SA1 are cut | disconnected, and the excess part of each sheet piece F1m, F2m remaining in a frame shape is cut off.

It is cut at the displaced position.

In addition, it is not limited to bonding a sheet piece to the area | region (for example, whole liquid crystal panel P) containing the said functional part in liquid crystal panel P. FIG. For example, the sheet piece is bonded previously to the area | region which avoided the said functional part in liquid crystal panel P, and after that, liquid crystal panel P in three sides except the said functional part in rectangular liquid crystal panel P in planar view. The excess portion may be laser cut along the outer circumference of.

In addition, the film bonding system is equipped with the 2nd detection apparatus 92 (refer FIG. 20).

The control apparatus 25 (refer FIG. 16) acquires the edge data of the 2nd bonding surface memorize | stored in the memory | storage device 24 (refer FIG. 16), and the 3rd optical member F13 makes the outer side (2nd of a liquid crystal panel P). The cut position of 3rd sheet piece F3m is determined so that it may become a size which does not protrude to the outer side of a joining surface. The second cutting device 52 cuts the third sheet piece F3m at the cut position determined by the control device 25.

The size of the avoided area is shown. In this embodiment, it is the magnitude | size of the external shape of the 2nd board | substrate P2.

The 3rd optical member F13 is bonded by the 2nd cutting device 52 to the other surface of the front and back of liquid crystal panel P by the excess part of 3rd sheet piece F3m being cut off from 4th optical member bonding body PA4. Fifth optical member bonding body PA5 formed by bonding the first optical member F11 and the second optical member F12 to one front and back surface of panel P is formed. At this time, the 5th optical member bonding body PA5 and the part corresponding to a 2nd bonding surface (3rd optical member F13) are cut out, and the excess part of 3rd sheet piece F3m which remains in a frame form is isolate | separated. The excess portion cut off from the third sheet piece F3m is peeled off from the liquid crystal panel P by a peeling apparatus (not shown) and recovered.

Here, the said "part corresponding to a 2nd bonding surface" is an area | region below the magnitude | size of the display area P4, the magnitude | size of the liquid crystal panel P outline shape, and shows the area | region which avoided functional parts, such as an electrical component installation part. In this embodiment, the excess part is laser-cut along the outer periphery of liquid crystal panel P in four sides in rectangular liquid crystal panel P by planar view. For example, when the part corresponding to a 2nd bonding surface is a bonding surface of a CF board | substrate, since there is no part corresponding to the said functional part, it cuts along the outer periphery of liquid crystal panel P in four sides of liquid crystal panel P.
