Description

The manufacturing system of optical display and the manufacturing approach of this optical display
Technical field
The present invention relates to a kind of manufacturing system of optical display and the manufacturing approach of this optical display.
Background technology
In the past, the optical display panel that on liquid crystal panel, was fitted with polarizing coating is made widely.Proposed a kind ofly when liquid crystal panel and polarizing coating are fitted, to emit rectangular reel polarizing coating, carried out the manufacturing system of applying of the liquid crystal panel of polarizing coating and single sheet.
For example, in patent documentation 1 and patent documentation 2, the device of applying blooming is disclosed.Through these devices, can carry out the applying of blooming with operating efficiency preferably.

[patent documentation 3] Japan publication communique " spy opens flat 8-208083 communique (on August 13rd, 1996 is open) "
Summary of the invention
[technical matters that invention will solve]
But, the not enough problem of production efficiency that there is optical display panel in said manufacturing system in the past.
Specify, in patent documentation 1 and the patent documentation 2 disclosed manufacturing systems, comprise a fixing portion that unreels of polarizing coating volume reel.Therefore, when used reel polarizing coating being involved in the row replacing, at first, the operator will make the production line of manufacturing system stop.Next, make the portion of unreeling carry out flatly moving in the volume core direction of reel polarizing coating volume.Then, the operator changes operation through in the portion that unreels that has moved horizontally used reel polarizing coating volume being fitted with the film end of new reel polarizing coating volume.
That is,, therefore, in the replacing operation, need a lot of time owing to need make the portion of unreeling after the volume core direction of reel polarizing coating volume moves horizontally, carry out the replacing operation of reel polarizing coating volume again.Make that consequently the manufacturing time of each piece optical display panel is longer, cause production efficiency to descend.
Again, the lamination process machine of record is through turret the reel polarizing coating to be involved in row to engage in the patent documentation 3.Such mode is applied under the situation of manufacturing system of optical display panel, needs the bigger place that is provided with that turret is set.Therefore, when engaging, need guarantee the space of turret rotation, make manufacturing system maximize.
The present invention proposes in view of above-mentioned problem points in the past just, and its purpose is, can shorten the manufacturing time of optical display, and the manufacturing system of the optical display of miniaturization is provided.
[technological means of dealing with problems]
In order to solve the problems of the technologies described above, the manufacturing system of optical display of the present invention is that the applying polarizing coating is to make the manufacturing system of optical display on liquid crystal panel, and it has: unreel portion, it unreels the polarizing coating of surface by the diaphragm protection; Stripping portion, it peels off diaphragm from said polarizing coating; Conveying mechanism, it carries liquid crystal panel to sticking part; Sticking part, it fits the said liquid crystal panel and the polarizing coating of being stripped from diaphragm; And reeling end, it will batch from the diaphragm that said polarizing coating has been peeled off, and the said portion of unreeling can flatly move with respect to the volume core direction of polarizing coating, unreels the portion that unreels of portion and the 2nd and is set up in parallel as said the 1st of the portion that unreels.
In above-mentioned manufacturing system; Having the 1st unreels portion and the 2nd and unreels two in portion and unreel portion; Even the changing bobbins with polarizing coating is not new reel; Also can adopt the 1st to unreel the polarizing coating that portion and the 2nd unreels portion and come immediately polarizing coating to be connected to each other, the polarizing coating of replacing is unreeled.Therefore, can cut down the required time of replacing operation of the reel polarizing coating of the portion of unreeling, therefore, a kind of manufacturing approach that shortens the manufacturing time of optical display can be provided.

Below, based on Fig. 1 to Fig. 5 an embodiment of the present invention is described.
(formation of the manufacturing system of optical display)
Fig. 1 is the sectional view that the manufacturing system 30 of optical display of the present invention is shown.Manufacturing system 30 with polarizing coating 10 or 20 and liquid crystal panel 2 fit.As liquid crystal panel 2, can use known liquid crystal panel, enumerate the known liquid crystal panel of configuration oriented film between the substrate of glass substrate etc. and liquid crystal layer.
As shown in Figure 1, each formation as manufacturing system 30 comprises: unreel portion's (the 1st unreels portion) 1, unreel portion's (the 2nd unreels portion) 11, film connecting portion (the 1st film connecting portion) 3, film connecting portion (the 2nd film connecting portion) 13 and conveying mechanism 12.In addition, as shown in Figure 2, comprising: the edge of a knife (stripping portion) 23 and niproll 2222a (" " in this instructions be " and " the meaning).
Unreeling portion 1 and unreeling portion 11 is the devices that keep the reel of polarizing coating 1020 respectively, is the structure that can adjust the tension force that imposes on polarizing coating 1020.The polarizing coating 10 of emitting from the portion of unreeling 1 is transported to the production line side through each guide reel.Also carry out same processing for the light polarizing film of emitting 20 from the portion of unreeling 11.
Unreel portion 1 and unreel portion 11 and be set up in parallel.In addition, unreel portion 1 and unreel portion 11 and constitute, can be respectively on the direction of the volume core 1a11a of polarizing coating 1020, flatly move.In other words, unreeling portion 1 can move on the Width of polarizing coating 10, and unreeling portion 11 can move on the Width of polarizing coating 20.More particularly; Shown in the left side of Fig. 1, constitute and to move at least one side (can to moving) perpendicular to inwards direction of paper (have in zero * mark) and perpendicular at least one side of the outside direction of paper (mark that has in zero) along the both direction of volume core 1a11a.Therefore, polarizing coating 10 or 20 surplus tail off, unreel portion 1 or unreel portion 11 on above-mentioned volume core direction, to move horizontally by the operator, and be new reel with the changing bobbins of polarizing coating.
Through above-mentioned structure, make when changing polarizing coating, the reel of new polarizing coating can be set in the portion of unreeling that above-mentioned horizontal direction moves.Therefore, different with the lamination process machine with turret, unreeling portion 111 needn't move to the top.Therefore, can dwindle the moving range of the portion of unreeling, a kind of manufacturing system of miniaturization is provided.
Especially unreel portion 111 and move in the horizontal direction, therefore, between portion of unreeling 111 and conveying mechanism 12, need not unreel the space that portion 111 moves usefulness.Consequently can dwindle the space between portion of unreeling 111 and the conveying mechanism 12, realize the miniaturization of manufacturing system 30.Can realize on such miniaturization this point that the application's invention is very different with the existing manufacturing system with turret.
Can adopt known polarizing coating as above-mentioned polarizing coating 1020.What polarizing coating of the present invention used is common rectangular polarizing coating.Specifically,, further constitute as diaphragm at the two sides of polarizer film applying TAC (Triafol T) film etc. through the TAC film laminated diaphragm of cementing agent on one side or two sides.As the polarizer film that is positioned at the center in the polarizing coating 10, can enumerate through iodine etc. polyvinyl alcohol film dyeing, on the film that is extended etc., be fitted with the film of the diaphragm of TAC etc.Can use part formalizing polyvinyl alcohol (PVA) mesentery, ethylene-vinyl acetate copolymer pastern to divide the polyenoid alignment film of hydrophilic macromolecule film etc. or the processed thing of polyvinyl alcohol (PVA), the dehydrochlorination handled thing of PVC etc. of saponification film, cellulose mesentery etc. to wait and replace above-mentioned polyvinyl alcohol (PVA) etc. again.
The total thickness that includes polarizing coating 10 and diaphragm does not have special qualification, can be for more than the 100 μ m, below the 500 μ m.Again, the thickness of the polarizer film in the polarizing coating 10 is more than the general 10 μ m, below the 50 μ m.Further, in the practical application of polarizing coating 10, in no problem scope, except above-mentioned 3 layers, can also comprise other layer.
Fig. 1 does not illustrate, and above-mentioned polarizing coating is protected by diaphragm on its surface.Between polarizing coating 10 and the diaphragm adhering agent layer is arranged, after diaphragm is stripped from, polarizing coating 10 and liquid crystal panel 2 are fitted through adhering agent layer.Said protection film can constitute the one side at polarizing coating 10, also can constitute the two sides at polarizing coating 10.
Can use polyester film, polyethylene terephthalate film etc. as said protection film.Again, the thickness of said protection film and width do not limit especially, consider from viewpoint as the diaphragm of polarizing coating, for example, preferably used thickness be that 5 μ m are above, below the 50 μ m, width is the diaphragm that 200mm is above, 1500mm is following.
Conveying mechanism 12 is delivered to liquid crystal panel 2 at niproll (sticking part) the 2222a place that itself and polarizing coating 10 (perhaps 20) are fitted.Conveying mechanism 12 disposes towards the throughput direction of polarizing coating 10, and is configured in the top of polarizing coating 10.Like this, the epimere at the portion that unreels 111 of hypomere, film connecting portion 313, the edge of a knife 23 disposes conveying mechanism 12 and niproll 2222a.Owing to dispose each member along last hypomere like this, therefore, can make manufacturing system 30 saving spaces.
The conveying mechanism 12 of manufacturing system 30 constitutes roll profile, as long as but can carry liquid crystal panel as conveying mechanism 12, might not be defined as roll profile.Through conveying mechanism 12 with the left side of liquid crystal panel 2 from figure to the right (niproll 2222a side) carry.Again, the stapling machine that does not illustrate among film connecting portion 313 and Fig. 1 is narrated hereinafter.
Below, utilize Fig. 2 that the applying of polarizing coating 10 and liquid crystal panel 2 is described.Fig. 2 illustrates the sectional view that niproll 2222a pays the structure of near manufacturing system 30.As shown in Figure 2, polarizing coating 10 is cut off, and through the adhering agent layer adhesion diaphragm is arranged.That is, in the stage before polarizing coating 10 arrives niproll 2222a,, polarizing coating 10 is cut into the size that is suitable for liquid crystal panel 2 applyings through hemisection cutter not shown in the figures.On the other hand, diaphragm 10a is not cut.
Again, the edge of a knife 23 disposes along diaphragm 10a.The side view of the edge of a knife 23 is a triangle, and the bottom surface of the edge of a knife 23 is configured to the direction that unreels along diaphragm 10a.The edge of a knife 23 is for to make that the friction force between the edge of a knife 23 and the diaphragm 10a is less, and diaphragm 10a is easy to the member peeled off from adhering agent layer, for example is made up of the member that utilizes DLC etc. to carry out surface working.Thus, diaphragm 10a then, is batched by not shown reeling end through moving along the edge of a knife 23 and peeling off and be removed from polarizing coating 10.For example can enumerate SUS304, SUS420 etc. as the material of such edge of a knife 23.
Above-mentioned reeling end is the device that batches diaphragm 10a, and its basic structure is the same with the portion of unreeling 1 or 11.Again, also can constitute and have 2 reeling ends, of the back literary composition, as connecting polarizing coatings, carry out the connection of diaphragm 10a through 2 film connecting portions through 2 film connecting portions.
The liquid crystal panel 2 that niproll 2222a will be carried by conveying mechanism 12 and polarizing coating 10 carry out crimping with its applying.The pressure of niproll 2222a when fitting can suitably be adjusted.
Fig. 3 is the stereographic map that film connecting portion 3 and stapling machine 7 are shown.As shown in Figure 3, film connecting portion 3 comprises adsorption section 44a and cuts off sticking part 5.
Adsorption section 44a is used for adsorbing and the fixing member of polarizing coating.Adsorption section 44a has writing board shape, and its surface has a plurality of adsorbing mechanisms 9.As long as adsorbing mechanism 9 can adsorb polarizing coating, not other special qualifications can be adopted by pump to attract the structure of air with the absorption polarizing coating.
Cutting off sticking part 5 can rotate, and has a plurality of.Specifically, cutting off sticking part 5 has polyhedron-shaped.Be configured to and rotate again.Further preferred mode is to move in vertical direction with respect to polarizing coating 10.Owing to can move in vertical direction, therefore when cutting off sticking part 5 rotations, cut off sticking part 5 and can rotate again afterwards to vertical with polarizing coating 10 and move away from the direction of polarizing coating 10 with respect to polarizing coating 10.Then, cut off sticking part 5 again to vertical with polarizing coating 10 and move and turn back to original position near the direction of polarizing coating 10.Thus, the rib portion that can avoid cutting off sticking part 5 contacts with polarizing coating 10, and is desirable in the extreme.
Again, it is polyhedron-shaped, as shown in Figure 4 cutting off sticking part 5, and three masks have the supporting surface of cut-out 5a, binding face 5b5c therein, but also can also have the supporting surface of cut-out and/or binding face.For example, can enumerate and have a structure of cutting off supporting surface, three or four binding faces, and have two structures of cutting off supporting surfaces, three or four binding faces.Again, cut-out sticking part 5 that kind of image pattern 3 in rib portion chamfering, are desirable from the angle of avoiding contacting with polarizing coating.The size of cut-out sticking part 5 can come according to the width of polarizing coating 10 suitably to determine, does not limit especially, and for example, length is that 200mm is above, 2000mm is following, width is more than the 10mm, below the 300mm.
Fig. 4 illustrates the stereographic map that cuts off sticking part 5.The cut-out sticking part 5 that Fig. 4 the illustrates Fig. 3 state after 1/3 week that turns clockwise.As shown in Figure 4; Cut off sticking part 5 have along the Width of polarizing coating 10 support polarizing coating 10 cut-out supporting surface 5a, have the cut-out binding face 5c binding face 5b more than 2 of the adsorbing mechanism 9 of absorption connecting elements, this connecting elements connects polarizing coating 1020 so that the cut-out line of cut polarizing coating 10 is covered.
Form the opening 6 of groove shape cutting off supporting surface 5a, form the structure that the part of the sword of the stapling machine 7 that cut-out sticking part 5 shown in Figure 3 had can be passed through.Through forming opening 6, stapling machine 7 is carried out through the Width along polarizing coating 10 reliably, and make the connection of polarizing coating 1020 to carry out exactly.
Stapling machine 7 can adopt known cutter, considers from the viewpoint that can easily cut off polarizing coating 10, and is more satisfactory for justifying bladed.Again, stapling machine 7 supports through the base portion 8 that can drive at the Width of polarizing coating 10.
Binding face 5b5c has same formation, and the same with adsorption section 44a have a plurality of adsorbing mechanisms 9.Again, on binding face 5b5c, dispose single face adhesive tape (connecting elements) 5d, the non-bonding plane of single face adhesive tape 5d is kept by adsorbing mechanism 9, and bonding plane is configured to the face opposite with binding face 5b5c.
As long as above-mentioned single face adhesive tape 5d can fit with polarizing coating, can adopt known single face adhesive tape.For example; Membrane material as adhesive tape; For example can enumerate polyethylene terephthalate film (PET film), cellulose, Japan paper, aluminium, nonwoven fabrics, teflon, PVC, polyvinylidene chloride, polycarbonate, polyurethane, ABS resin, polyester, polystyrene, tygon, polypropylene, gather acetal resin, PLA, polyimide, polyamide etc.Again; As the employed sticker of adhering agent layer, can enumerate the sticker of acrylic acid series, epoxy system, polyurethane series, synthetic rubber system, EVA system, silicone-based, vinyl chloride, neoprene system, cyanoacrylate system, isocyanate-based, polyethenol series, melamine resin system etc.
It is relative with polarizing coating 10 that film connecting portion 3 is configured to.Therefore, in Fig. 1, polarizing coating 10 is by arranged perpendicular, and therefore, film connecting portion 3 is also with respect to polarizing coating 10 arranged perpendicular.On the other hand, also can make such structure, that is, at polarizing coating 10 for example under the situation of vergence direction (perhaps horizontal direction etc.) configuration, also vergence direction (perhaps horizontal direction etc.) configuration of film connecting portion 3.
Film connecting portion 13 is structures same with film connecting portion 3.As shown in Figure 1, the adsorbing mechanism 9 that film connecting portion 313 is configured to the adsorption section 4 (adsorption section 4a) that film connecting portion 313 had against each other.Again, film connecting portion 313 is configured to passing through between the position between polarizing coating 10 and polarizing coating 20.Again, the manufacturing system 30 with film connecting portion 313 is preferred implementations of this embodiment, and the mode that does not have a film connecting portion 313 also is fine.
(action of the manufacturing system of optical display)
Below, the action of the manufacturing system 30 of this embodiment is described.In addition, the explanation of relevant this action is double is the explanation of the manufacturing approach of optical display.
At first, as shown in Figure 1, from the portion of unreeling 1 polarizing coating 10 is unreeled (unreeling operation).Then, as shown in Figure 2, only polarizing coating 10 is carried out hemisection through not shown hemisection cutter, peel off diaphragm 10a (stripping process) through the edge of a knife 23.Further, through niproll 22,22a the liquid crystal panel 2 and the polarizing coating 10 of being stripped from diaphragm 10a are carried out crimping with fit (bonding process).The diaphragm 10a of being stripped from addition, is batched, is reclaimed through not shown reeling end.Through above-mentioned a series of operation, liquid crystal panel 2 is fitted with polarizing coating 10, can obtain optical display.
In above-mentioned a series of operation, along with polarizing coating 10 is unreeled, the residual volume that is maintained at the reel of the polarizing coating 10 in the portion of unreeling 1 reduces.Down in the face of polarizing coating connection operation connected to one another is described.
Connecting operation does; Cut off the above-mentioned the 1st polarizing coating and the 2nd that unreels portion and unreel the polarizing coating of portion, with the polarizing coating 10 of the portion of unreeling 1 and unreel the portion that unreels 1 in the polarizing coating 20 of portion 11 or unreel polarizing coating 10 or the polarizing coating 20 of the production line side (ラ イ Application side) of portion 11, with the portion of unreeling 11 or unreel the perhaps operation that is connected of polarizing coating 10 of polarizing coating 20 of the portion that the unreels side of portion 1.Above-mentioned " production line side " in other words, is the direction that the expression polarizing coating is unreeled.As above-mentioned connection operation, can enumerate the method that film connecting portion 313 is adopted through operating personnel's method and (2) in (1).
At first, carry out bright specifically to the method for passing through operating personnel of (1).Connecting through operating personnel under the situation of two polarizing coatings, the transporting velocity of polarizing coating 10 is being made as after the 0m/min (make polarizing coating 10 stop after), operating personnel cut off polarizing coating 10.Next, have for example from 11 pairs of polarizing coatings 20 of the portion of unreeling to unreel, after having cut off the end, for example adopt above-mentioned single face adhesive tape 5d to connect the method for polarizing coating.
Like this, in manufacturing system 30 of the present invention, have 111 two in the portion of unreeling and unreel portion,, also can adopt polarizing coating 1020 that symphysis is connect, thereby can promptly unreel polarizing coating 20 even if be not new reel with the changing bobbins of polarizing coating.Therefore, only be provided with 1 place to unreel the manufacturing system of portion different, can carry out the replacing operation of reel polarizing coating volume, therefore can cut down the required time of operation of changing an on-stream idle side portion of unreeling with existing.Its result can shorten the manufacturing time of optical display.In manufacturing system 30, after the connection of accomplishing polarizing coating 1020, during polarizing coating 20 is unreeled, be new reel with the changing bobbins of the polarizing coating 10 of the portion of unreeling 1.Under the situation that the surplus of polarizing coating 20 has reduced, can certainly likewise connect polarizing coating 20 and polarizing coating 10.
Next, utilize Fig. 5 to carry out bright specifically to the situation that adopts film connecting portion 313.Fig. 5 is the process chart that the connection operation of manufacturing system 30 is shown.When the surplus of polarizing coating 10 reduces, shown in Fig. 5 (a) of polarizing coating 10, the transporting velocity of polarizing coating 10 is made as after the 0m/min, makes adsorption section 44a and cut off sticking part 5 (film connecting portion 3) and move to the vertical direction of polarizing coating 10.Next, the adsorbing mechanism 9 through adsorption section 44a adsorbs polarizing coating 10 and be fixed (absorption process).
At this moment, the cut-out supporting surface 5a of cut-out sticking part 5 contacts with polarizing coating 10.Then, shown in Fig. 5 (b), not shown stapling machine is moved along opening 6, and polarizing coating 10 is cut off (cut-out operation).After the cut-out; Make and cut off sticking part 5 to vertical with polarizing coating 10 and move away from the direction (left side among the figure) of polarizing coating 10; And it was turned clockwise for 1/3 week, make to cut off sticking part 5 again to vertical with polarizing coating 10 and move near the direction (right side among the figure) of polarizing coating 10.Thus, shown in Fig. 5 (c), the single face adhesive tape 5d that sticks binding face 5b is to cover the cut-out line (bonding process) of the polarizing coating 10 relative with single face adhesive tape 5d (figure does not show).What above-mentioned cut-out line was represented is the limit relative with binding face 5b in the section that on polarizing coating 10, produces through cutting off operation.In bonding process, single face adhesive tape 5d is configured to cover above-mentioned cut-out line, that is, single face adhesive tape 5d crosses above-mentioned cut-out line, even if also dispose in the part that does not have polarizing coating 10.
Further, for polarizing coating 20, likewise single face adhesive tape 15d is adhered on the cut-out supporting surface 15a of polarizing coating 20 with Fig. 5 (d)～(e).Member to identical with above-mentioned member is given identical title, omits its explanation.
At first, unreel from 11 pairs of polarizing coatings 20 of the portion of unreeling, with Fig. 5 (a) likewise, after the end that has cut off polarizing coating 20, not shown stapling machine is moved, along being formed on the opening that cuts off on the supporting surface 15a to cut off polarizing coating 20.After the cut-out; Make and cut off sticking part 15 to vertical with polarizing coating 20 and move away from the direction (right side among the figure) of polarizing coating 20; And make it be rotated counterclockwise for 1/3 week, make to cut off sticking part 15 again to vertical with polarizing coating 20 and move near the direction (left side among the figure) of polarizing coating 20.Thus, shown in Fig. 5 (e), can stick single face adhesive tape 15d to cover the cut-out line of the polarizing coating 20 relative with the single face adhesive tape 15d of binding face 15b.
Next; Shown in Fig. 5 (f); Make adsorption section 44a and cut off sticking part 5 (the symphysis tipping puts 3) near adsorption section 14,14a and cut off sticking part 15 (film connecting portion 13), make the section of polarizing coating 10 and polarizing coating 20 be fitted to each other together (near operation).Thus, cover the part that having crossed among the single face adhesive tape 5d15d of cut-out line of polarizing coating 1020 cut off line (part of not fitting with polarizing coating 1020) and fit, connect polarizing coating 1020 thus with the opposing party's polarizing coating 2010.In Fig. 5 (f), make film connecting portion 3 approaching, but it is approaching to film connecting portion 3 also can to make symphysis meet portion 13 to film connecting portion 13, can also make film connecting portion 313 approaching each other.
After having connected polarizing coating 1020; As preparatory process, shown in Fig. 5 (g), make and cut off sticking part 515 respectively to vertical with polarizing coating 1020 and move away from the direction of polarizing coating 1020; Make cut-out sticking part 5 be rotated counterclockwise for 1/3 week, cut-out sticking part 15 was turned clockwise for 1/3 week.And, make and cut off sticking part 515 respectively to vertical with polarizing coating 1020 and move near the direction of polarizing coating 1020.
At last, make adsorption section 44a and cut off the position that sticking part 5 (film connecting portion 3) is got back to Fig. 5 (a), finish a series of operation.In addition; Single face adhesive tape 5d15d is arranged on the binding face 5c15c with the state that is adsorbed in advance; Therefore after the reel of new polarizing coating 10 is set at the portion of unreeling 1, polarizing coating 20 is carried out the operation of Fig. 5 (a)～(c), polarizing coating 10 is carried out the operation of Fig. 5 (d)～(e); Via the operation of Fig. 5 (f)～(h) of above-mentioned that kind, can be so that polarizing coating 2010 connects.Through replenishing the single face adhesive tape 5d15d that uses, can certainly connect polarizing coating continuously again.
As stated, under the situation of the connection operation of having used film connecting portion 313, compare with the operation of implementing through operating personnel that is connected, can be in the shorter time and carry out absorption, cut-out, the applying of polarizing coating more accurately, therefore comparatively desirable.
Specifically, in this manufacturing system 30, implementing through operating personnel to connect under the situation of operation, needing about 10 minutes, but under the situation of using film connecting portion 313, can make to connect the needed time of operation below 1 minute.
In addition, in this manufacturing system 30, only using the portion 1 that unreels; Do not use the portion of unreeling 11; Also do not use under the situation of film connecting portion 313, operating personnel need change polarizing coating 10 again after changing to new polarizing coating in the portion of unreeling 1, therefore connect the operation needs about 30 minutes.Therefore, the manufacturing system of this example is helpful is conspicuous.
The present invention is not limited to each above-mentioned embodiment; Can shown in the claim scope in carry out various changes, with different embodiment disclosed respectively technical method carry out the embodiment that suitable combination obtains and be also contained in the technical scope of the present invention.For example, the quantity of the guide reel of manufacturing system, the configuration etc. that unreels portion, reeling end, film connecting portion and conveying mechanism all are not limited to illustrated configuration.

Thus, through above-mentioned adsorption section absorption polarizing coating, can support to utilize under the state of adsorbed polarizing coating stapling machine to cut off this polarizing coating to cut off supporting surface.Then, can make and cut off the sticking part rotation, the connection material of binding face is fitted on the polarizing coating that has been cut off.Further, can make the 1st film connecting portion and the 2nd film connecting portion near each other, and two polarizing coatings contacts that are fitted with the connection material are also easily connected.
Again, in the manufacturing system of optical display of the present invention, be preferably, on above-mentioned cut-out supporting surface, be formed with the opening that above-mentioned stapling machine can pass through along the Width of above-mentioned polarizing coating.
Thus, can carry out passing through of stapling machine reliably along the Width of polarizing coating, can after carry out the mutual connection of polarizing coating more accurately.
In addition, in the manufacturing system of optical display of the present invention, above-mentioned stapling machine is preferably round bladed.
Thus, can more easily carry out the cut-out of polarizing coating.
Again, in the manufacturing system of optical display of the present invention, be preferably, above-mentioned cut-out sticking part can move on the vertical direction that is adsorbed the adsorbed polarizing coating of portion.
Thus, when cutting off the sticking part rotation, cut off sticking part can vertical with polarizing coating and away from the direction of polarizing coating on move, can be rotated then.Thus, when cutting off the sticking part rotation, can avoid cutting off sticking part reliably and contact with polarizing coating.
