The second cutter sweep 16 is positioned at the panel of nip roll 15b and carries downstream.With reference to Fig. 2 and Fig. 5, the second cutter sweep 16 cuts the sheet material F1S of the first optical component sheet F1 of the first single-sided lamination panel P11 of the second optical component sheet F2 and surface laminating thereon simultaneously in the lump.The second cutter sweep 16 is for example CO2 laser cutting machine, cuts circlewise the sheet material F1S of the second optical component sheet F2 and the first optical component sheet F1 along the outer peripheral edges of viewing area P4 (in the present embodiment along liquid crystal panel P outer peripheral edges).After each optical component sheet F1, F2 being conformed to liquid crystal panel P, concentrate cutting, can improve the precision of the optical axis direction of each optical component sheet F1, F2, and eliminate the deviation of the optical axis direction between each optical component sheet F1, F2, and simplify the cutting of the first cutter sweep 13.
By the cutting of the second cutter sweep 16, form the second single-sided lamination panel P12 of the superimposed lower surface (with reference to Fig. 7) that is fitted in liquid crystal panel P of the first and second optical component F11, F12.Again, now, the second single-sided lamination panel P12 separates with the remainder of each optical component sheet F1, F2, and the remainder of described each optical component sheet F1, F2 is to be the remaining part of frame shape after cutting the part relative with viewing area P4 (each optical component F11, F12).The remainder of the second optical component sheet F2 is multiple to be connected and to form ladder shape (with reference to Fig. 2), is reeled to the second recoverer 15d together with the remainder of this remainder and the first optical component sheet F1.
At this, so-called " part relative with viewing area P4 " be represent to have that the size of viewing area P4 is above, big or small region below the size of the outer shape of liquid crystal panel P, and represent to have avoided the region of the funtion parts such as electric parts installation portion.In the present embodiment, having overlooked as the removal of the liquid crystal panel P of rectangle three limits of described funtion part, along the outer peripheral edges cut remainder of liquid crystal panel P.On the one side that is equivalent to described funtion part, suitably enter P4Ce position, viewing area cut remainder in the outer peripheral edges from liquid crystal panel P again.
With reference to Fig. 1, the 3rd calibrating installation 17 makes surface and the back side upset of the second single-sided lamination panel P12 using the display surface side of liquid crystal panel P as upper surface, the backlight side that makes liquid crystal panel P is upper surface, and carries out the calibration same with the described first and second calibrating installation 11,14.; the 3rd calibrating installation 17, based on being stored in the detection data of the optical axis direction in control device 20 and the camera data of described camera C, carries out the second location of single-sided lamination panel P12 in part Width and sense of rotation with respect to the 3rd laminating apparatus 18.Under this state, the second single-sided lamination panel P12 is directed to the laminating position of the 3rd laminating apparatus 18.
As shown in Fig. 1 and Figure 10, the 3rd laminating apparatus 18 has: conveying device 19, described conveying device 19 on one side from around rolled up the 3rd optical component sheet F3 and with it the 3rd coiled material R3 of overlapping partition SS unreel the 3rd optical component sheet F3 and partition SS carries them on one side, and cut out the 3rd optical component F13 and be supplied to the position of fitting from the 3rd optical component sheet F3; And nip roll 21, the upper surface of described nip roll 21 cuts out conveying device 19 the 3rd optical component F13 from the 3rd optical component sheet F3 conforms to the lower surface (the display surface side of liquid crystal panel P) of the second single-sided lamination panel P12 that roller path 5 carries.
Conveying device 19 is carried multiple the 3rd optical component F13 continuously using partition SS as carrier.The 3rd optical component sheet F3 and partition SS are made into rectangular band shape, it has the width corresponding with the viewing area P4 of liquid crystal panel P (being equivalent in the present embodiment, the width below the overall with of the above and liquid crystal panel P of the overall with of viewing area P4) on described part Width.Partition SS and the 3rd optical component sheet F3 (the 3rd optical component F13) can fit together overlappingly discretely.Below, the combination of partition SS and the 3rd optical component sheet F3 is called to the 3rd optical component lamellar body F3S.
Conveying device 19 has: roller maintaining part 19a (unreeling portion), and it keeps the 3rd coiled material R3, and unreels the 3rd optical component lamellar body F3S from the 3rd coiled material R3 along the length direction of the 3rd optical component lamellar body F3S; Single or multiple (only illustrating in the drawings one) guide reel 19b, its for along regulation sheet material transport path by the 3rd optical component lamellar body F3S unreeling from the 3rd coiled material R3 guide to the 3rd laminating apparatus 18 laminating position and around volume the 3rd optical component lamellar body F3S partition SS side; Cutter sweep 19c (cutting part), it implements the residual hemisect of partition SS to the 3rd optical component lamellar body F3S on sheet material transport path; Edge of a knife 19d, its partition SS side volume extension by the 3rd optical component lamellar body F3S that has implemented hemisect acutangulates, and makes the 3rd optical component F13 separate from partition SS on one side, the 3rd optical component F13 is supplied to laminating position on one side; And partition recoverer 19e, it batches through edge of a knife 19d and becomes independent partition SS.
The roller maintaining part 19a that is positioned at the starting point of conveying device 19 for example synchronously drives mutually with the partition recoverer 19e of the terminal that is positioned at conveying device 19.Thus, when roller maintaining part 19a unreels the 3rd optical component lamellar body F3S to the throughput direction of the 3rd optical component lamellar body F3S, partition recoverer 19e batches via edge of a knife 19d and becomes independent partition SS.
Unreeled in specified length at the 3rd optical component lamellar body F3S, the residual partition SS of the overall with ground that cutter sweep 19c crosses over the Width orthogonal with the length direction (unreeling direction) of the 3rd optical component lamellar body F3S cuts (only cutting off the 3rd optical component sheet F3) to the 3rd optical component lamellar body F3S.Cutter sweep 19c adjusts the advance and retreat position of cutting tool, to make the partition SS can be because the tension force acting in the conveying of the 3rd optical component lamellar body F3S breaks.
On the 3rd optical component lamellar body F3S after described cutting, be formed with the line of cut of the overall with of the Width of crossing over the 3rd optical component lamellar body F3S.
At this, near the top ends of edge of a knife 19d, position that near the panel laminating position of the 3rd laminating apparatus 18 is carried upstream side, what be provided with that the cut end that unreels direction downstream of the 3rd optical component F13 to this position detects first detects camera 22.The first detection information that detects camera 22 is sent to control device 20.Control device 20 for example detects that at the first detection camera 22 moment of the downstream side of the 3rd optical component F13 temporarily stops conveying device 19.Thereafter, the moment of the downstream side of the second single-sided lamination panel P12 detected at the first detection camera 22, control device 20 drives conveying device 19, makes the synchronous laminating position that also they can be directed into the 3rd laminating apparatus 18 of the second single-sided lamination panel P12 and the 3rd optical component F13.
On the other hand, the first detection camera 22 unreel direction upstream side, compare cutter sweep 19c be positioned at a 3rd optical component F13 degree described in unreel the position in direction downstream, be provided with equally the cut end that unreels direction downstream of the 3rd optical component F13 is detected second detect camera 23 (test section).The second detection information that detects camera 23 is also sent to control device 20.Control device 20 is for example unreeled after the cutting of having carried out the 3rd optical component sheet F3 by cutter sweep 19c, in the moment that this cut end (line of cut of the upstream side of the 3rd optical component sheet F3) detected at the second detection camera 23, conveying device 19 is temporarily stopped.Now, adopt cutter sweep 19c to carry out the cutting of the 3rd optical component sheet F3., be equivalent to the length of the 3rd optical component F13 along the distance of the sheet material transport path between the detection position (being equivalent to the optical axis extended position of the detection of second on the 3rd optical component sheet F3 camera 23) of the second detection camera 23 and the cutting position of cutter sweep 19c (being equivalent to the cutting tool advance and retreat position of the cutter sweep 19c on the 3rd optical component sheet F3).
For example, in the case of cutting out the 3rd optical component F13 of the liquid crystal panel P that fits in same size, on the length direction of the 3rd optical component lamellar body F3S, equally spaced form described line of cut.The 3rd optical component sheet F3 is divided into multiple regions in the longitudinal direction by multiple lines of cut, and the region by clipping at the adjacent a pair of line of cut of length direction on the 3rd optical component sheet F3 is made into respectively the 3rd optical component F13.The length of the 3rd optical component F13 is set in the present embodiment more than the total length of viewing area P4 and below the total length of liquid crystal panel P.
Again, cutter sweep 19c is set to and can moves along the sheet material transport path of the 3rd optical component lamellar body F3S.Move by this, along the distance change of the sheet material transport path between the detection position of the second detection camera 23 and the cutting position of cutter sweep 19c.The control device 20 that moves through of cutter sweep 19c is controlled, for example, in the time adopting cutter sweep 19c the 3rd optical component sheet F3 to be unreeled to the distance of a 3rd optical component F13 degree after carrying out the cutting of the 3rd optical component sheet F3, its cut end departs from the situation of assigned position, revises this deviation by the movement of cutter sweep 19c.
In addition, also can carry out by the movement of cutter sweep 19c the cutting of the 3rd optical component F13 that corresponding length is different.Again, also can make by cutter sweep 19c and the second at least one party who detects camera 23 are moved at sheet material throughput direction, carry out the structure of the length change of described correction or the 3rd optical component F13.Again, it is close to each other that cutter sweep 19c and second detects camera 23, but in order to prevent from being accompanied by the second vibration that detects camera 23 of movement etc. of cutter sweep 19c, cutter sweep 19c and second detects camera 23 and supports more satisfactory by other framework respectively.
Edge of a knife 19d is configured in the below of roller path 5, and at least overall with extension along the 3rd optical component lamellar body F3S on the Width of the 3rd optical component lamellar body F3S.Edge of a knife 19d hangs the 3rd optical component lamellar body F3S volume to acutangulate, to contact with the partition SS Slideslip of the 3rd optical component lamellar body F3S after hemisect.
The 3rd optical component lamellar body F3S is in acute angle turns back at edge of a knife 19d, and the 3rd optical component F13 is separated from partition SS.The panel of edge of a knife 19d and nip roll 21 carries the downstream near-earth that joins to be configured.The lower surface of the liquid crystal panel P that the 3rd optical component F13 one side and the roller path 5 separating from partition SS by edge of a knife 19d carried is overlapping, is imported between a pair of doubling roller of nip roll 21 on one side.
Nip roll 21 has a pair of doubling roller that direction of principal axis is configured in parallel to each other.
Between a pair of doubling roller, be formed with the gap of regulation, in this gap, become the laminating position of the 3rd laminating apparatus 18.In described gap, the second single-sided lamination panel P12 and the 3rd optical component F13 overlap and are imported into.These second single-sided laminations panel P12 and the 3rd optical component F13 are clamped on one side between described doubling roller, are sent to panel on one side and carry downstream.Thus, be formed on the two sides laminating panel P13 (with reference to Fig. 7) that is fitted with the 3rd optical component F13 on the second single-sided lamination panel P12.
Two sides laminating panel P13 has after zero defect (fit bad etc.) via not shown defect detecting device is detected, is transported to lower procedure and carries out other processing.
At this, usually, the resin molding uniaxial tension that rectangular blooming (being equivalent to each optical component sheet F1, F2, F3) has made with dichromatism pigment dyeing is manufactured, and the optical axis direction of blooming is roughly consistent with the bearing of trend of resin molding.But the optical axis of blooming in blooming entirety and heterogeneity, has uneven slightly at the Width of blooming.
Therefore, fit multiple optics demonstration parts on the Width of blooming, the calibration of carrying out optics demonstration part according to the optical axis direction of blooming is desirable.
This is to suppressing optical axis uneven of optical display means unit and improving excellent degree and contrast is very effective.
In order to block the light except the light of single direction vibration, for example, by iodine, dichroic dye etc., the blooming as polarizing coating is dyeed.In addition, also can be on blooming further lamination mold release film or diaphragm.
The pick-up unit that detects the optical axis direction of blooming has: be configured in the light source near the position of a face in surface and the back side of blooming; And analyzer, described analyzer is configured in the position near another face in surface and the back side of blooming, and is configured in the opposition side of light source.Analyzer, by receiving the light that irradiates and see through blooming from light source, detects this light intensity, thereby detects the optical axis of blooming.Analyzer can move at the Width of for example blooming, can (place of selecting according to service condition) detect optical axis in any place of the Width of blooming.
The in the situation that of present embodiment, lengthwise location and the width position of the detection data of the each optical component sheet F1 being obtained by described pick-up unit, the optical axis direction of F2, F3 and each optical component sheet F1, F2, F3 are stored in the storer of control device 20 explicitly.After this detection, batch each optical component sheet F1, F2, F3, form respectively each coiled material R1, R2, R3.Below, each optical component sheet F1, F2, F3 are generically and collectively referred to as optical component sheet FX, are fitted in the liquid crystal panel P of each optical component sheet F1, F2, F3 and each single-sided lamination panel P11, P12 and are generically and collectively referred to as optics and show part PX.
At this, the polarizer film uniaxial tension that forms optical component sheet FX by for example dichromatism pigment dyeing PVA film form, but the dyeing inhomogeneous or dichromatism pigment of the thickness of the PVA film during due to stretching is inhomogeneous etc., has in the Width inner side of optical component sheet FX and the tendency of the different optical axis directions of Width outside generation.
Therefore, in the present embodiment, based on the detection data that distribute in the face of the optical axis of the each several part of the pre-stored optical component sheet FX of control device 20, the optics that fits in this shows the calibration of part PX, and optics is shown to part PX is fitted on optical component sheet FX.
Specifically, laminating optics in optical component sheet FX shows in the face at position of part PX, for example find out with respect to the optical axis of angle maximum of the reference axis (longitudinal axis etc.) of regulation and minimum optical axis, average optical axis makes using the binary axle in angle that these each optical axises are formed as this position, carries out the calibration that optics shows part PX take this axle as benchmark.
Thus, even fit on the different position of the Width of optical component sheet FX, optics shows part PX, the optical axis direction that also can suppress optical component sheet FX shows reference position uneven of part PX with respect to optics, can make optical axis tolerance be roughly 0 ° (allowable tolerance be ± 0.25 °).
In addition, also can unreel optical component sheet FX in limit, frontier inspection photometer axis direction, carries out based on these detection data the calibration that optics shows part PX.Again, the optical axis direction that above-mentioned all calibration stepss do not limit optical component sheet FX is the situation of 0 ° and 90 °, is also set to the situation of arbitrarily angled (showing the angle of the object of part according to optics) applicable to optical axis direction.
Again, Fig. 3 is illustrated in the example that three optics of fitting side by side on the Width of the optical component sheet FX with wider width show part PX.The present invention is not limited to the example shown in Fig. 3, also can adopt the optics of fitting side by side on the Width of optical component sheet FX below two or more than four to show the structure of part PX, also can adopt at Width and arrange the narrower optical component sheet FX of multiple width, and the optics of fitting respectively on these optical component sheets FX represents the structure of part PX.
With reference to Fig. 4, liquid crystal panel P has: the rectangular first substrate P1 being made up of for example TFT substrate; Configuration relative with first substrate P1 be similarly rectangular second substrate P2; And by the liquid crystal layer P3 between inclosure first substrate P1 and second substrate P2.In addition, in illustrated situation, sometimes omit the profile line of each layer of sectional view.
With reference to Fig. 6, make three edges of the outer peripheral edges of first substrate P1 the three corresponding limits of second substrate P2, and the remaining one side of outer peripheral edges is extended to the outside on corresponding one side of second substrate P2.Thus, be provided with at a described avris of first substrate P1 the electric parts installation portion P5 extending to the outside of second substrate P2.
With reference to Fig. 5, the outer peripheral edges of the test section detection display region P4 such as camera 16a for the second cutter sweep 16 limits, the cutting such as the outer peripheral edges of viewing area, edge P4 the first and second optical component sheet F1, F2.At the G of architrave portion of the arranged outside Rack of viewing area P4, in the width of the G of this architrave portion, utilize each cutter sweep 16,19 to carry out cut, the described architrave G of portion configuration engages first and the sealant of second substrate P1, P2 etc.
As shown in Figure 9, if the independent resinous optical component sheet of cut FX, the cut end t of optical component sheet FX expands because thermal deformation produces or rises and falls.Therefore, show part PX in the case of the optical component sheet FX after cut being conformed to optics, it is bad that optical component sheet FX easily produces the laminating such as entrained air or distortion.
On the other hand, as shown in Figure 8, after optical component sheet FX being fitted in to liquid crystal panel P, in the present embodiment of cut optical component sheet FX, the cut end t of optical component sheet FX is supported in the glass surface of liquid crystal panel P.Therefore, owing to not producing expansion or the fluctuating etc. of cut end t of optical component sheet FX, and after liquid crystal panel P laminating optical component sheet FX, therefore can not produce described laminating bad.
On liquid crystal panel P, cut optical component sheet FX such in the situation that, the error width (tolerance) of the line of cut of laser machine is less than the error width of the line of cut of cutting tool.Therefore in the present embodiment, compared with using the situation of cutting tool cutting optical component sheet FX, can dwindle the width of the described architrave G of portion, can make liquid crystal panel P miniaturization and (or) viewing area P4 maximizes.Such optical component sheet to size as smart mobile phone in recent years or touch screen terminal, restriction housing and being suitable for of high-performance mobile information terminal that requires to expand display frame be also effective.
At this, owing to being transported to other production line and being fitted in liquid crystal panel P after the sheet material that optical component sheet FX is cut into the viewing area P4 that is incorporated into liquid crystal panel P, dimensional tolerence separately of described sheet material and liquid crystal panel P and these the relatively dimensional tolerence of laminating positions are overlapping, and the width that therefore dwindles the G of architrave portion of liquid crystal panel P becomes difficulty (expand viewing area and become difficulty).
On the other hand, optical component sheet FX is being fitted in after liquid crystal panel, in the situation of viewing area P4 cutting optical component sheet FX, is only considering that the deviation tolerance of line of cut just can dwindle the width tolerance of the G of architrave portion (± 0.1mm below).This point also can dwindle the width (expand viewing area and become possibility) of the G of architrave portion of liquid crystal panel P.
Further, by without cutter but with the optical component sheet FX on cut liquid crystal panel P, dynamics when cutting does not input to liquid crystal panel P, is difficult to produce crack or defect at the ora terminalis of the substrate of liquid crystal panel P, improves the permanance for thermal cycle etc.Same, due to Fluid Contacting crystal panel P not, also few for the infringement of electric parts installation portion P5.
Again, the 3rd laminating apparatus 18 cuts into the 3rd banded optical component sheet F3 with the width corresponding with viewing area P4 specified length and forms the 3rd optical component F13.The 3rd laminating apparatus 18 is carried the 3rd optical component F13 on one side together with partition SS, they is fitted in to the second single-sided lamination panel P12 on one side in the production line that carries out described cutting.Therefore, and will be delivered to according to the manufactured Polarizer of viewing area P4 compared with the such situation of other production line, the uneven or uneven impact of fitting of the CHI-pulse and CUN-pulse being irregular of the 3rd optical component F13 is suppressed.
As shown in Figure 6, in the case of using cut optical component sheet FX (the second optical component sheet F2 in Fig. 6), for example the starting point pt1 of cut is set on the extended line on a long limit of viewing area P4, first starts to cut a described long limit from this starting point pt1.The terminal pt2 of cut is set in the position of laser on the extended line of the minor face of the starting point side of viewing area P4 mono-circle arrival viewing area P4.Starting point pt1 and terminal pt2 are set to the coupling part that leaves regulation at the remainder of optical component sheet FX, thereby can tolerate the tension force while batching optical component sheet FX.
As described above, the production system of the optical display means of above-mentioned embodiment is, forming optical component F11, F12, F13 is fitted in the film applying system 1 of a part of the production system of the upper and optical display means that forms of liquid crystal panel P, comprise: laminating apparatus 12, 15, described laminating apparatus 12, 15 show part PX for multiple optics of carrying on roller path 5, limit is from coiled material R1, R2 unreels banded optical component sheet F1, F2, limit is fitted in the first optical component sheet F1 by the first surface of the second optical component sheet F2 and multiple liquid crystal panel P (face in surface and the back side) successively and makes the second adhesive piece F22, described optical component sheet F1, F2 is showing that with optics the orthogonal part Width of the throughput direction of part PX has the width larger than the width of the viewing area of liquid crystal panel P, and second cutter sweep 16, described the second cutter sweep 16 passes through the described optical component sheet F1 relative with described viewing area P4, the relative part of F2 is cut open with the remainder in the outside that is positioned at described relative part, and from described optical component sheet F1, F2 cuts out the optical component F11 with size corresponding to described viewing area P4, F12, thereby cut out the second single-sided lamination panel P12 from described the second adhesive piece F22, described the second single-sided lamination panel P12 comprises single described liquid crystal panel P and the described optical component F11 overlapping with described liquid crystal panel P, F12, and the 3rd cutter sweep 18, described the 3rd cutter sweep 18 is for multiple described the second single-sided lamination panel P12 carrying on roller path 5, the 3rd banded optical component sheet F3 on described part Width with the width corresponding with described viewing area P4 is unreeled from the 3rd coiled material R3 together with partition SS, unreel the 3rd optical component sheet F3 with the length corresponding with described viewing area P4 at every turn and just on the 3rd optical component sheet F3, implement the cutting along Width, after making and thering is the 3rd big or small optical component F13 corresponding with described viewing area P4, carry multiple described the 3rd optical component F13 using described partition SS as carrier, described the 3rd optical component F13 is fitted in to the second (face contrary with first surface of the described liquid crystal panel P on described the second single-sided lamination panel P12 simultaneously, another side in surface and the back side) on.
According to this structure, the 3rd banded optical component sheet F3 with the width corresponding with viewing area P4 is cut into specified length and forms the 3rd optical component F13, on one side the partition SS unreeling is carried to the 3rd optical component F13 as carrier together with the 3rd optical component sheet F3, on one side in the production line that carries out described cutting at liquid crystal panel P laminating the 3rd optical component F13.Therefore, with will be delivered to according to the manufactured Polarizer of viewing area P4 compared with the such situation of other production line, can suppress the CHI-pulse and CUN-pulse being irregular of the 3rd optical component F13 uneven or fit uneven, the G of architrave portion that dwindles viewing area P4 periphery, seeks the expansion of viewing area and the miniaturization of equipment.
By by combined the laminating of the 3rd optical component sheet F3 after the cutting of optical component sheet F1, F2 and the hemisect of residual partition SS that conform to after liquid crystal panel P, can seek dwindling and the shortening of productive temp time of the G of architrave portion again.
Again, described the 3rd laminating apparatus 18 of the production system of above-mentioned optical display means has: roller maintaining part 19a, and it unreels described the 3rd optical component sheet F3 together with described partition SS; Cutter sweep 19c, it implements to cut and make described the 3rd optical component F13 to described the 3rd optical component sheet F3; Second detects camera 23, it is compared with implementing the cutting position of cutting to described the 3rd optical component sheet F3, in the position that side downstream separates the distance corresponding with described the 3rd optical component F13 that unreels in direction of described the 3rd optical component sheet F3, the line of cut being formed on by described cutting on described the 3rd optical component sheet F3 is detected; And control device 20, in the time described line of cut being detected from the described cutting position detection position that side separates the distance of described a 3rd optical component F13 downstream, control device 20 is adjusted the distance between described cutting position and described detection position according to the position of described line of cut.
According to this structure, be positioned at compared with the cutting position of the 3rd optical component sheet F3 a 3rd optical component F13 degree downstream second detect camera 23 detect described the 3rd optical component F13 unreel direction downstream side time, by cutter sweep 19c, the 3rd optical component sheet F3 is implemented to be cut into possibility, can obtain the 3rd optical component F13 of specified length.Even if the volume production that unreels of the 3rd optical component sheet F3 is given birth to error, also can revise (absorption) to described error by the relatively moving of cutter sweep 19c of the detection information based on the second detection camera 23 again.Therefore, can guarantee the precision of the length of the 3rd optical component F13, and the cutting of the 3rd optical component F13 that also can be different from length is corresponding.
At this, the production method of the optical display means in above-mentioned embodiment is, show part PX for multiple optics of carrying on roller path 5, limit is from coiled material R1, R2 unreels and is showing the banded optical component sheet F1 on the orthogonal part Width of the throughput direction of part PX with the width larger than the width of the viewing area P4 of liquid crystal panel P with optics, F2, limit is fitted in the first surface of the second optical component sheet F2 and multiple liquid crystal panel P on the first optical component sheet F1 and makes the second adhesive piece F22 successively, by by the described optical component sheet F1 relative with described viewing area P4, the relative part of F2 is cut open with the remainder in the outside that is positioned at described relative part, and from described optical component sheet F1, F2 cuts out the optical component F11 with size corresponding to described viewing area P4, F12, thereby cut out the second single-sided lamination panel P12 from described the second adhesive piece F22, described the second single-sided lamination panel P12 comprises single described liquid crystal panel P and the described optical component F11 overlapping with described liquid crystal panel P, F12, for multiple described the second single-sided lamination panel P12 carrying on roller path 5, the 3rd banded optical component sheet F3 on described part Width with the width corresponding with described viewing area P4 is unreeled from the 3rd coiled material R3 together with partition SS, unreel the 3rd optical component sheet F3 with the length corresponding with described viewing area P4 at every turn and just on the 3rd optical component sheet F3, implement the cutting along Width, after making and thering is the 3rd big or small optical component F13 corresponding with described viewing area P4, carry multiple described the 3rd optical component F13 on one side using described partition SS as carrier, on one side described the 3rd optical component F13 is fitted on second of described liquid crystal panel P on described the second single-sided lamination panel P12.
In addition, Figure 11 illustrates the variation of film applying system 1.It is with respect to the structure of Fig. 1, has the first laminating apparatus 12 ' that replaces described the first laminating apparatus 12, and replaces in the first cutter sweep 13 ' this point of described the first cutter sweep 13 especially different.To other structures structure identical with described embodiment in variation, give same-sign, detailed.

Nip roll 112b has a pair of doubling roller that direction of principal axis configures in parallel to each other.Between a pair of doubling roller, form the gap of defined, in this gap, become the laminating position of the first laminating apparatus 112.In described gap, liquid crystal panel P and the first optical component sheet F1 overlap and are imported into.These liquid crystal panels P and the first optical component sheet F1 limit are clamped between described doubling roller, and limit is sent panel and carries downstream.Thus, form the compartment of terrain of vacating regulation at lower surface the first adhesive piece F21 of the multiple liquid crystal panel P of laminating continuously of the first rectangular optical component sheet F1.
The first cutter sweep 113 is positioned at the panel of pf recoverer 112d and carries downstream.In the lump with reference to Fig. 4 and Fig. 5, the first cutter sweep 113 forms than the sheet material F1S of viewing area P4 large (also large than liquid crystal panel P in the present embodiment) in order to cut the first optical component sheet F1 of the first adhesive piece F21, cuts the defined position (between the liquid crystal panel P arranging at throughput direction) of the first optical component sheet F1 across the whole width of described part Width.In addition, the first cutter sweep 113 also can use cutting tool, or laser cutting tool.By described cutting, the upper surface that is formed on liquid crystal panel P is fitted with the first single-sided lamination panel P11 of the described sheet material F1S larger than viewing area P4.
With reference to Figure 13, the second calibrating installation 114 keeps the first single-sided lamination panel P11 on roller path 105 for example, and makes it around 90 ° of rotations of Z-axis.Thus, the first single-sided lamination panel P11 being transferred substantially in parallel with the minor face of viewing area P4 turns, thereby is transferred substantially in parallel with the long limit of viewing area P4.In addition, described in, being rotated in other the optical axis direction of optical component sheet that fits in liquid crystal panel P at right angles carries out in the situation of configuration with respect to the optical axis direction of the first optical component sheet F1.
The second calibrating installation 114 carries out the calibration same with described the first calibrating installation 111.; the second calibrating installation 114, based on being stored in the inspection data of the optical axis direction in control device 120 and the camera data of described camera C, carries out the location part Width and sense of rotation in of the first single-sided lamination panel P11 with respect to the second laminating apparatus 115.Under this state, the first single-sided lamination panel P11 is directed to the laminating position of the second laminating apparatus 115.
The second laminating apparatus 115 conforms to the upper surface (backlight side of liquid crystal panel P) that is delivered to the first single-sided lamination panel P11 below the second optical component sheet F2 the lower surface of the second rectangular optical component sheet F2 that is directed to laminating position.The second laminating apparatus 115 has: conveying device 115a, described conveying device 115a, on one side from unreeling the second optical component sheet F2 around the second coiled material R2 that has rolled up the second optical component sheet F2, carries the second optical component sheet F2 along the length direction of the second optical component sheet F2 on one side; And nip roll 115b, the upper surface of the first single-sided lamination panel P11 that described nip roll 115b carries roller path 105 conforms to the lower surface of the second optical component sheet F2 of conveying device 115a conveying.
Conveying device 115a has: roller maintaining part 115c, and described roller maintaining part 115c keeps around the second coiled material R2 that has rolled up the second optical component sheet F2, and ceaselessly emits the second optical component sheet F2 along the length direction of the second optical component sheet F2; And the second recoverer 115d, described the second recoverer 115d reclaims the remainder through the second optical component sheet F2 of the second cutter sweep 116, and described the second cutter sweep 116 is positioned at the panel of nip roll 115b and carries downstream.Conveying device 115a is at the transport path of the laminating set positions second optical component sheet F2 of the second laminating apparatus 115, thereby the binding face that makes the second optical component sheet F2 that is fitted in the first single-sided lamination panel P11 downward.
Nip roll 115b has a pair of doubling roller that direction of principal axis configures in parallel to each other.Between a pair of doubling roller, form the gap of defined, in this gap, become the laminating position of the second laminating apparatus 115.In described gap, the first single-sided lamination panel P11 and the second optical component sheet F2 overlap and are imported into.These first single-sided laminations panel P11 and the second optical component sheet F2 limit are clamped between described doubling roller, and limit is sent to panel and carries downstream.Thus, form the compartment of terrain of vacating regulation multiple the first single-sided lamination panel P11 fitted in continuously the second adhesive piece F22 of the lower surface of the second rectangular optical component sheet F2.
The second cutter sweep 116 is positioned at the panel of nip roll 115b and carries downstream.In the lump with reference to Figure 14 and Fig. 5, the second cutter sweep 116 cuts the second optical component sheet F2 and the sheet material F1S at the first optical component sheet F1 of the first single-sided lamination panel P11 of its lower surface laminating simultaneously.The second cutter sweep 116 has the structure identical with the second cutter sweep 16 of the first embodiment.By using the second cutter sweep 116, can improve the precision of the optical axis direction of each optical component sheet F1, F2, and eliminate the deviation of the optical axis direction between each optical component sheet F1, F2, and simplify the cutting of the first cutter sweep 13.
By the cutting of the second cutter sweep 116, be formed on overlapping the second single-sided lamination panel P12 that is fitted with the first and second optical component F11, F12 (with reference to Fig. 7) of upper surface of liquid crystal panel P.Again, now, the second single-sided lamination panel P12 separates with the remainder of each optical component sheet F1, F2, and the remainder of described each optical component sheet F1, F2 is to cut the part relative with viewing area P4 (each optical component F11, F12) and residue is the part of frame shape.The remainder of the second optical component sheet F2 is multiple to be connected and to be formed as ladder shape (with reference to Figure 14), is reeled to the second recoverer 115d together with the remainder of this remainder and the first optical component sheet F1.
With reference to Figure 13, the 3rd calibrating installation 117 makes surface and the back side upset of the second single-sided lamination panel P12 using the backlight side of liquid crystal panel P as upper surface, the display surface side that makes liquid crystal panel P is upper surface, and carries out the calibration same with the described first and second calibrating installation 111,114.; the 3rd calibrating installation 117; based on being stored in the detection data of the optical axis direction in control device 120 and the camera data of described camera C, carry out the second single-sided lamination panel P12 with respect to the location in location and the sense of rotation on part Width of the 3rd laminating apparatus 118.Under this state, the second single-sided lamination panel P12 is directed to the laminating position of the 3rd laminating apparatus 118.
As shown in Figure 13 and Figure 16, the 3rd laminating apparatus 118 has: conveying device 119, described conveying device 119 on one side from around rolled up the 3rd optical component sheet F3 and with it the 3rd coiled material R3 of overlapping partition SS unreel the 3rd optical component sheet F3 and partition SS carries on one side, and cut out the 3rd optical component F13 and be supplied to the position of fitting from the 3rd optical component sheet F3; And nip roll 121, the upper surface (the display surface side of liquid crystal panel P) of the second single-sided lamination panel P12 that described nip roll 121 is carried roller path 105 conforms to the lower surface of the 3rd optical component F13 that conveying device 119 cuts out from the 3rd optical component sheet F3.
The conveying device 19 of conveying device 119 and the first embodiment is similarly carried multiple the 3rd optical component F13 continuously using partition as carrier.Conveying device 119 has: roller maintaining part 119a (unreeling portion), and it keeps the 3rd coiled material R3, and unreels the 3rd optical component lamellar body F3S from the 3rd coiled material R3 along the length direction of the 3rd optical component lamellar body F3S; Single or multiple (only illustrating in the drawings one) guide reel 119b, it is in order to guide to the laminating position of the 3rd laminating apparatus 118 by the 3rd optical component lamellar body F3S unreeling from the 3rd coiled material R3 and to roll up the partition SS side of hanging the 3rd optical component lamellar body F3S along the sheet material transport path of regulation; Cutter sweep 119c (cutting part), it implements the residual hemisect of partition SS to the 3rd optical component lamellar body F3S on sheet material transport path; Edge of a knife 119d, its partition SS side volume extension by the 3rd optical component lamellar body F3S that has implemented hemisect acutangulates, and makes the 3rd optical component F13 separate from partition SS on one side, three optical component F13 is supplied to laminating position on one side; And partition recoverer 119e, it batches through edge of a knife 119d and becomes independent partition SS.
The roller maintaining part 119a that is positioned at the starting point of conveying device 119 for example synchronously drives mutually with the partition recoverer 119e of the terminal that is positioned at conveying device 119.Thus, when roller maintaining part 119a unreels the 3rd optical component lamellar body F3S to the throughput direction of the 3rd optical component lamellar body F3S, partition recoverer 119e batches via edge of a knife 19d and becomes independent partition SS.
Unreeled in specified length at the 3rd optical component lamellar body F3S, the residual partition SS of the overall with ground that cutter sweep 119c crosses over the Width orthogonal with the length direction (unreeling direction) of the 3rd optical component lamellar body F3S cuts (only cutting off the 3rd optical component sheet F3) to the 3rd optical component lamellar body F3S.Cutter sweep 119c adjusts the advance and retreat position of cutting tool, to make the partition SS can be because the tension force acting in the conveying of the 3rd optical component lamellar body F3S breaks.
On the 3rd optical component lamellar body F3S after described cutting, be formed with the line of cut of the overall with of the Width of crossing over the 3rd optical component lamellar body F3S.
At this, near the top ends of edge of a knife 119d, position that near the panel laminating position of the 3rd laminating apparatus 118 is carried upstream side, what be provided with that the cut end that unreels direction downstream of the 3rd optical component F13 to this position detects first detects camera 122.The first detection information that detects camera 122 is sent to control device 120.Control device 120 for example detects that at the first detection camera 122 moment of the downstream side of the 3rd optical component F13 temporarily stops conveying device 119.Thereafter, the moment of the downstream side of the second single-sided lamination panel P12 detected at the first detection camera 122, control device 120 drives conveying device 119, makes the synchronous laminating position that also they can be directed into the 3rd laminating apparatus 118 of the second single-sided lamination panel P12 and the 3rd optical component F13.
On the other hand, the first detection camera 122 unreel direction upstream side, compare cutter sweep 119c be positioned at a 3rd optical component F13 degree described in unreel the position in direction downstream, be provided with equally the cut end that unreels direction downstream of the 3rd optical component F13 is detected second detect camera 123.The second detection information that detects camera 123 is also sent to control device 120.Control device 120 is for example unreeled after the cutting of having carried out the 3rd optical component sheet F3 by cutter sweep 119c, in the moment that this cut end (line of cut of the upstream side of the 3rd optical component sheet F3) detected at the second detection camera 123, conveying device 119 is temporarily stopped.Now, adopt cutter sweep 119c to carry out the cutting of the 3rd optical component sheet F3., be equivalent to the length of the 3rd optical component F13 along the distance of the sheet material transport path between the detection position (being equivalent to the optical axis extended position of the detection of second on the 3rd optical component sheet F3 camera 123) of the second detection camera 123 and the cutting position of cutter sweep 119c (being equivalent to the cutting tool advance and retreat position of the cutter sweep 119c on the 3rd optical component sheet F3).
Again, cutter sweep 119c is set to and can moves along the sheet material transport path of the 3rd optical component lamellar body F3S.Move by this, along the distance change of the sheet material transport path between the detection position of the second detection camera 123 and the cutting position of cutter sweep 119c.The control device 120 that moves through of cutter sweep 119c is controlled, for example, in the time adopting cutter sweep 119c the 3rd optical component sheet F3 to be unreeled to the distance of a 3rd optical component F13 degree after carrying out the cutting of the 3rd optical component sheet F3, its cut end departs from the situation of assigned position, revises this deviation by the movement of cutter sweep 119c.
In addition, also can carry out by the movement of cutter sweep 119c the cutting of the 3rd optical component F13 that corresponding length is different.Again, can make by cutter sweep 119c and the second at least one party who detects camera 123 are moved at sheet material throughput direction, carry out the structure of the length change of described correction or the 3rd optical component F13.Again, it is close to each other that cutter sweep 119c and second detects camera 123, but in order to prevent from being accompanied by the second vibration that detects camera 123 of movement etc. of cutter sweep 119c, cutter sweep 119c and second detects camera 123 and supports more satisfactory by other framework respectively.
Edge of a knife 119d is configured in the below of roller path 105, and at least overall with extension along the 3rd optical component lamellar body F3S on the Width of the 3rd optical component lamellar body F3S.Edge of a knife 119d hangs the 3rd optical component lamellar body F3S volume to acutangulate, to contact with the partition SS Slideslip of the 3rd optical component lamellar body F3S after hemisect.
The 3rd optical component lamellar body F3S is in acute angle turns back at edge of a knife 119d, and the 3rd optical component F13 is separated from partition SS.The panel of edge of a knife 119d and nip roll 121 is carried the downstream near-earth configuration of joining.The upper surface of the liquid crystal panel P that the 3rd optical component F13 one side and the roller path 105 separating from partition SS by edge of a knife 119d carried is overlapping, is imported between a pair of doubling roller of nip roll 121 on one side.
Nip roll 121 has a pair of doubling roller that direction of principal axis configures in parallel to each other.Between a pair of doubling roller, form the gap of defined, in this gap, become the laminating position of the 3rd laminating apparatus 118.In described gap, the second single-sided lamination panel P12 and the 3rd optical component F13 overlap and are imported into.These second single-sided laminations panel P12 and the 3rd optical component F13 limit are clamped between described doubling roller, and limit is sent to panel and carries downstream.Thus, be formed on the two sides laminating panel P13 that is fitted with the 3rd optical component F13 on the second single-sided lamination panel P12.(with reference to Fig. 7).
Identical with the cutter sweep 19 of above-mentioned the first embodiment, two sides laminating panel P13 has after zero defect (fit bad etc.) via not shown defect detecting device is detected, is transported to lower procedure and carries out other processing.
Again, same with the control device 20 of above-mentioned the first embodiment, the in the situation that of present embodiment, lengthwise location and the width position of the inspection data of the each optical component sheet F1 being obtained by described pick-up unit, the optical axis direction of F2, F3 and each optical component sheet F1, F2, F3 are stored in the storer of control device 120 explicitly.Again, same with above-mentioned the first embodiment, thus after inspection, batch each optical component sheet F1, F2, F3 form respectively coiled material R1, R2, R3.
In the present embodiment, identical with the control device 20 of the first embodiment, based on the detection data that distribute in the face of the optical axis of the each several part of the pre-stored optical component sheet FX of control device 120, the optics that fits in this shows the calibration of part PX, and optics is shown to part PX is fitted on optical component sheet FX.Thus, obtain the effect identical with the first embodiment.
Again, Figure 15 is illustrated in the example that three optics of fitting side by side on the Width of the wider optical component sheet FX of width show part PX, but be not limited thereto, also can be that fit side by side on the Width of optical component sheet FX optics below two or more than four shows the structure of part PX, also can be to arrange the narrower optical component sheet FX of multiple width at Width, and go up separately at them the structure that the optics of fitting respectively represents part PX.
With reference to Fig. 5, the outer peripheral edges of the test section detection display region P4 such as camera 116a for the second cutter sweep 116 limits, the cutting such as the outer peripheral edges of viewing area, edge P4 the first and second optical component sheet F1, F2.There is the G of architrave portion of Rack in the arranged outside of viewing area P4, in the width of the G of this architrave portion, utilize the second cutter sweep 116 to carry out cut, the sealant of the described architrave G of portion configuration joint first and second substrate P1, P2 etc.
By using such cutter sweep, can obtain the effect same with the first embodiment (with reference to Fig. 9 and Figure 10).
Again, the 3rd laminating apparatus 118 cuts into the 3rd banded optical component sheet F3 with the width corresponding with viewing area P4 specified length and forms the 3rd optical component F13.The 3rd laminating apparatus 118 is carried the 3rd optical component F13 on one side together with partition SS, they is fitted in to the second single-sided lamination panel P12 on one side in the production line that carries out described cutting.Therefore, and will be delivered to according to the manufactured Polarizer of viewing area P4 compared with the such situation of other production line, the uneven or uneven impact of fitting of the CHI-pulse and CUN-pulse being irregular of the 3rd optical component F13 is suppressed.
As shown in Figure 6, in the case of using cut optical component sheet FX (the second optical component sheet F2 in Fig. 6), for example the starting point pt1 of cut is set on the extended line on a long limit of viewing area P4, first starts to cut a described long limit from this starting point pt1.The terminal pt2 of cut is set in to the position on laser encloses the starting point side that the arrives viewing area P4 extended line of minor face around viewing area P4 mono-.Starting point pt1 and terminal pt2 are set as staying at the remainder of optical component sheet FX the coupling part of regulation, thereby can tolerate the tension force while batching optical component sheet FX.
