According to Fig. 1～Figure 13, an example of the present invention is described, as described below, but the present invention is not limited thereto.First, below the formation of manufacturing system of the present invention (manufacturing system of liquid crystal indicator) is described.Manufacturing system comprises laminating apparatus of the present invention.
Fig. 1 is the sectional view that manufacturing system is shown.As shown in Figure 1, manufacturing system 100 is double-decker, 1F (1 layer) part is film conveying mechanism 50, the laminating apparatus 60 of 2F (2 layers) part for containing substrate carrying mechanism (the 1st substrate carrying mechanism and the 2nd substrate carrying mechanism).
< film conveying mechanism >
First, film conveying mechanism 50 is described.Film conveying mechanism 50 roles are, polarizing coating (polarization plates) unreeled, until polarizing coating is transported to niproll 6,6a and 16,16a, and unnecessary stripping film is batched.On the other hand, laminating apparatus 60 roles are that the polarizing coating unreeling by film conveying mechanism 50 is fitted on substrate (liquid crystal panel) 5.
Film conveying mechanism 50 has the 1st film conveying mechanism 51 and the 2nd film conveying mechanism 52.Polarizing coating is delivered to niproll 6,6a by the 1st film conveying mechanism 51, and this niproll 6,6a are fitted in polarizing coating the lower surface of substrate 5 at first.In addition, substrate 5 has rectangular shape.On the other hand, the 2nd film conveying mechanism 52 is delivered to polarizing coating the lower surface of the substrate 5 being reversed.
The 1st film conveying mechanism 51 has: the 1st unreels portion 1, the 2nd unreels the 1a of portion, the 1st reeling end 2, the 2 reeling end 2a, half cutter 3, the edge of a knife 4 and defect film winding roller 7,7a.The 1st unreels in portion 1 and is provided with the reel that polarizing coating is rolled into, and polarizing coating is unreeled.Can adopt known polarizing coating as above-mentioned polarizing coating.Specifically, can use the film that adopts iodine etc. to dye to polyvinyl alcohol film and to extend to 1 direction of principal axis etc.The thickness of above-mentioned polarizing coating is not particularly limited, but can preferably use the polarizing coating of 5 μ m above, below 400 μ m.
For above-mentioned polarizing coating reel, the direction of absorption axes is positioned at mobile direction (MD direction).Above-mentioned polarizing coating is protected adhesive phase by stripping film.As above-mentioned stripping film (can be called diaphragm or separation layer), can use polyester film, polyethylene terephthalate film etc.The thickness of above-mentioned stripping film is not particularly limited, but can preferably use the stripping film of 5 μ m above, below 100 μ m.
In manufacturing system 100, there are two and unreel portion and two reeling ends corresponding with the portion that unreels, therefore, in the case of the 1st surplus that unreels the reel of portion 1 tails off, can make to be arranged at the 2nd and unreel polarizing coating that polarizing coating volume and the 1st on the 1a of portion unreels portion 1 and roll up and be connected.Its result, can not make unreeling of polarizing coating stop proceeding operation.Based on this formation, can enhance productivity.In addition, above-mentioned portion and the reeling end of unreeling can be respectively arranged with multiplely, can certainly arrange more than three.
Shown in Fig. 1 the 1st unreels portion 1, the 2nd, and to unreel the 1a of portion be the structure that can change by turret mutual alignment.Changing when position, the 1st unreels portion 1, the 2nd unreels the track that the 1a of portion describing circle and moves, can automatically cut off the 1st unreel the polarizing coating of portion 1 after, be automatically connected with the 2nd polarizing coating that unreels the 1a of portion.The 1st unreels portion 11, the 2nd, and to unreel the 11a of portion be also the same.About the 1st reeling end the 2, the 2nd reeling end 2a, the 1st reeling end the 12, the 2nd reeling end 12a, be also configured to the structure of rotating by turret again.Adopt this structure of turret, advantage be the portion of unreeling each other or reeling end can easily exchange each other, can easily carry out polarizing coating connection each other.
Again, the structure shown in exemplary graph 2 is as the variation that unreels portion and reeling end.The 1st of Fig. 2 unreels the 1b of portion, the 2nd and unreels the 1c of portion and be configured to, can be with respect to the direction of the volume core 1d of polarizing coating along moving horizontally.In other words, the 1st unreels the 1b of portion, the 2nd unreels the 1c of portion and is configured to, and can on the Width of polarizing coating, move.Specifically, as shown in the right part of Fig. 2, be configured to and can move at least one party of the both direction along volume core 1d (can to perpendicular to direction inwards of paper (have in zero × mark) and move perpendicular at least one party of the outside direction of paper (mark having in zero)).The 1st unreel the 1b of portion, the 2nd and unreel the 1c of portion and be set up in parallel mutually again.
Adopt this formation, changing polarizing coating volume in the situation that, can be with respect to flatly the mobile the 1st unreeling the 1b of portion or the 2nd and unreel the 1c of portion new polarizing coating volume is set in the direction at volume core 1d.Therefore, different from the formation with turret, the 1st unreels the 1b of portion, the 2nd unreels the 1c of portion and is not moved upward.
As shown in Figure 2, unreel the 1b of portion the 1st, the 2nd top that unreels the 1c of portion is provided with laminating apparatus 60, but adopt this structure, unreel the 1b of portion, the 2nd to unreel the 1c of portion be the structure moving horizontally in the direction of volume core 1d due to the 1st, therefore do not need the space of guaranteeing that the portion of unreeling is moved upward.Therefore, can save and be arranged at the transfer roller 15 on top and unreel the space between portion.Its result, can provide a kind of laminating apparatus being miniaturized and even manufacturing system.Can realize in such miniaturization this point, the present application is very different with the existing manufacturing system with turret.The manufacturing system with turret is for example open by Japanese kokai publication hei 8-208083 communique.
In addition, in the case of be arranged at the 1st unreel polarizing coating on the 1b of portion around volume surplus tails off, be connected with the 2nd polarizing coating that unreels the 1c of portion by operating personnel.At this moment,, after the transporting velocity of polarizing coating is made as to 0m/min, operating personnel cut off the 1st polarizing coating that unreels the 1b of portion side.Next, unreel the 1c of portion from the 2nd polarizing coating is unreeled, after having cut off end, for example, adopt one side adhesive tape that polarizing coating is interconnected.
Again, about the 1st reeling end the 2, the 2nd reeling end 2a, the 1st reeling end the 12, the 2nd reeling end 12a of Fig. 1, also can with Fig. 2 to unreel portion the same, make the structure that can move horizontally with respect to the direction of the volume core of stripping film.Again, being set up in parallel at the 1st reeling end 2 and the 2nd reeling end 2a is also identical in this point.Further, by reeling end being made to this formation (being the formation that the 1st reeling end, the 2nd reeling end structure that can move horizontally with respect to the direction of the volume core of stripping film and the 1st reeling end and the 2nd reeling end are set up in parallel), can save the space between transfer roller 15 and reeling end, laminating apparatus and even the manufacturing system of miniaturization more may be provided.
The polarizing coating (film laminated body being made up of polarizing coating, adhesive phase and stripping film) that 3 pairs of half cutters (cutting portion) are stripped from film protection carries out hemisection, to cut off polarizing coating and adhesive phase.Can use known member as half cutter 3.Specifically, can enumerate sword device, laser cutting machine etc.After having cut off polarizing coating and adhesive phase by half cutter 3, remove stripping film by the edge of a knife (removal portion) 4 from polarizing coating.
Between polarizing coating and stripping film, be coated with adhesive phase, after having removed stripping film, adhesive phase remains in polarizing coating side.As above-mentioned adhesive phase, be not particularly limited, can enumerate the adhesive phase of acrylic acid series, epoxy system, poly-ammonia ethyl ester system etc.The thickness of adhesive phase is not particularly limited, but is generally 5～40 μ m.
On the other hand, the 2nd film conveying mechanism 52 has the formation identical with the 1st film conveying mechanism 51, possess: the 1st unreels portion 11, the 2nd unreels the 11a of portion, the 1st reeling end 12, the 2 reeling end 12a, half cutter 13, the edge of a knife 14 and defect film winding roller 17,17a.About the member that adopts same member title, there is the effect identical with the member of the 1st film conveying mechanism 51.
As better example, manufacturing system 100 has cleaning part 71.Cleaning part 71 is cleaning base plate 5 before the lower surface that by niproll 6,6a, polarizing coating is fitted in to substrate 5.As cleaning part 71, can adopt the known cleaning part being formed by nozzle and the brush etc. of jet cleaning liquid.Be about to utilize cleaning part 71 cleaning base plates 5 before laminating, thereby can fitting in adhering under the less state of foreign matter of substrate 5.
Next, adopt Fig. 3 to describe the edge of a knife 4.Fig. 3 is the sectional view of the peripheral part of niproll 6 that manufacturing system 100 is shown, 6a.Fig. 3 represents the situation that substrate 5 is transferred from lower left to the polarizing coating 10a that is transferred, has adhesive phase (figure does not show, later identical) from left.On polarizing coating 10a, there is stripping film 10b, cut off polarizing coating 10a and adhesive phase by half cutter 3, peel off rete 10b and be not cut off (hemisection).
Be provided with the edge of a knife 4 in stripping film 10b side.The edge of a knife 4 is the bladed members for stripping film 10b is peeled off, and the stripping film 10b low with the cohesive force of polarizing coating 10a is stripped from along the edge of a knife 4.
Then, stripping film 10b is batched on the 1st reeling end 2 of Fig. 1.In addition, also can adopt and replace the edge of a knife by the formation that adhesive roller is batched stripping film.Now, with reeling end similarly, by adhesive roller being set at 2 places, can improve the efficiency of batching of stripping film.
< laminating apparatus >
Next, laminating apparatus 60 is described.Laminating apparatus 60 conveying substrates 5, fit in the polarizing coating of carrying by film conveying mechanism 50 on substrate.Though not shown, laminating apparatus 60 provides clean air to the upper surface of substrate 5.The rectification, flowing downward.Thus, can under stable state, carry out conveying and the laminating of substrate 5.
Laminating apparatus 60 is arranged on the top of film conveying mechanism 50.Thus, can realize the save space of manufacturing system 100.Although not shown, on laminating apparatus 60, be provided with the substrate carrying mechanism with transfer roller, thus to throughput direction conveying substrate 5 (the 1st substrate carrying mechanism the 61, the 2nd substrate carrying mechanism 62 described later is equivalent to substrate carrying mechanism in Figure 10).
In manufacturing system 100, substrate 5 is transferred from left side, then, to right side in figure, carries to the top of the 2nd film conveying mechanism 52 from the top of the 1st film conveying mechanism 51.Between film conveying mechanism 50 and laminating apparatus 60, be respectively arranged with niproll 6,6a (the 1st sticking part) and niproll 16,16a (the 2nd sticking part) as sticking part.Niproll 6,6a and 16,16a have been the members that the polarizing coating that has been removed stripping film is fitted in to the task of the lower surface of substrate 5.In addition, owing to polarizing coating being fitted to from below to the two sides of substrate 5, therefore utilizing after niproll 6,6a fit, substrate 5 is reversed by switching mechanism 65.To narrate in the back about switching mechanism 65.
The polarizing coating of carrying to niproll 6,6a is fitted in the lower surface of substrate 5 by adhesive phase.As niproll 6,6a, can adopt respectively the known formation such as crimping roller, backer roll.Again, pressure and the temperature when laminating of niproll 6,6a can be carried out suitable adjustment.The formation of niproll 16,16a too.In addition, although not shown, in manufacturing system 100, as comparatively ideal formation, be to unreel and between portion's 1,11 to half cutter, there is Flaw display (mark) test section the 1st, thereby detect the formation of the defective polarizing coating of tool.
In addition, above-mentioned Flaw display is in the time generating polarizing coating reel, to detect and the Flaw display given or represent that by being arranged on than defect test section the more close the 1st unreels Flaw display assigning unit that portion 1 and/or the 1st unreels portion's 11 sides and give the Flaw display of polarizing coating.Flaw display assigning unit is made up of filming apparatus, image processing apparatus and Flaw display forming portion.First, utilize above-mentioned filming apparatus to take polarizing coating, by processing this photographing information, can check having or not of defect.As above-mentioned defect, specifically, there are for example foreign matter, the shrinkage cavity etc. of dust etc.In the situation that defect being detected, utilize Flaw display forming portion on polarizing coating, to form Flaw display.Use the marks such as ink as Flaw display.
Further, not shown laminating avoids portion to differentiate above-mentioned mark by filming apparatus, sends stop signal and the conveying of substrate 5 is stopped to laminating apparatus 60.Then, the polarizing coating that is detected defect is not fitted by niproll 6,6a, but is batched by defect film winding roller (recoverer) 7,7a.Thus, can avoid the defective polarizing coating of substrate 5 and tool to fit together.If there is this series of formation, can avoid the defective polarizing coating of tool and substrate 5 to fit together, therefore can improve yield rate, more satisfactory.Can suitably adopt known inspection sensor to avoid portion as defects detection portion and laminating.
As shown in Figure 1, after substrate 5 becomes rollover states by switching mechanism 65, substrate 5 is transported to niproll 16,16a.And polarizing coating is fitted in the lower surface of substrate 5.Its result, the polarizing coating of all having fitted on two surfaces of substrate 5, becomes two polarizing coatings and is fitted in mutual different absorption axes two lip-deep states of substrate 5.Then, as required, whether produce laminating deviation for two surface inspections of substrate 5.The formation that this inspection can adopt inspection portion by having filming apparatus etc. to check conventionally.
Like this, in manufacturing system 100, the formation from fitting below substrate 5 in the time fitting polarizing coating to substrate 5, can not hinder the rectification environment to substrate 5.Therefore, can prevent that foreign matter from sneaking into the binding face of substrate 5, can fit more accurately.
Fig. 4 (a) and Fig. 4 (b) illustrate the velocity of the air-flow of the manufacturing system of the lower subsides type same with the present invention.Region A in Fig. 4 (a), (b) is the region that is provided with the portion of unreeling, and region B is mainly the region that polarizing coating passes through, and region C is the region that is provided with reeling end etc.Provide clean air from HEPA filtrator 40 again.In addition, in Fig. 4 (a), due to the grid 41 that is provided with clean air and can passes through, air-flow can move in vertical direction by grid 41.On the other hand, in Fig. 4 (b), due to grid 41 not being set, so air-flow is after contacting with base plate, move along base plate.
Manufacturing system shown in Fig. 4 (a), (b) is lower subsides type, therefore can as shown in Figure 14 (a), (b), not be subject to the obstruction of polarizing coating from the air-flow of HEPA filtrator 40.Therefore, the direction of air-flow vector is almost the direction towards substrate, can say that dust free room realized comparatively desirable rectification environment.In Fig. 4 (a), be provided with grid 41, in Fig. 4 (b), grid is not set, two figure demonstrate same desirable state.In addition, in Fig. 4 and Figure 14, substrate carrying mechanism is that level forms, but is not set to a series of structure.Therefore, becoming air-flow can be by the formation between substrate carrying mechanism.Be configured to such structure, that is, substrate is transferred after keeping by switching mechanism described later between substrate carrying mechanism.
Again, be configured to, in manufacturing system 100, first to grow limit as front (long limit and throughput direction are orthogonal) conveying substrate 5, afterwards, take minor face as front (minor face and throughput direction are orthogonal) conveying substrate 5.
(formation of film connecting portion)
Further, the further variation of laminating apparatus of the present invention is described.Fig. 5 is the sectional view that the variation of laminating apparatus 60 of the present invention is shown.The 1st of the 1st film conveying mechanism 51 of Fig. 5 unreels the 1b of portion, the 2nd and unreels the 1c of portion, and being similarly configured to Fig. 2 can be with respect to the direction of the volume core 1d of polarizing coating along the structure moving horizontally.
The 1st film conveying mechanism 51 has film connecting portion (the 1st film connecting portion) 83 and film connecting portion (the 2nd film connecting portion) 93, can carry out the connection of polarizing coating 10,20 by these film connecting portions.
Fig. 6 is the stereographic map that film connecting portion 83 and stapling machine 87 are shown.As shown in Figure 6, film connecting portion 83 has adsorption section 84,84a and cuts off sticking part 85.
Adsorption section 84,84a are the members for adsorbing polarizing coating and being fixed.Adsorption section 84,84a have writing board shape, have multiple adsorbing mechanisms 89 on its surface.As long as adsorbing mechanism 89 can adsorb polarizing coating, be not particularly limited, can adopt by pump and attract the formation of air with absorption polarizing coating.
Cutting off sticking part 85 can rotate, and has multiple.Specifically, cutting off sticking part 85 has polyhedron-shaped.Be configured to rotate again.Further, as comparatively ideal form, can move to vertical direction with respect to polarizing coating 10.Owing to moving to the vertical direction of polarizing coating 10, cutting off sticking part 85 while rotating, cutting off sticking part 85 can, to vertical with polarizing coating 10 and move away from the direction of polarizing coating 10, then, can be rotated.Then, cutting off sticking part 85 can be to vertical with polarizing coating 10 and move near the direction of polarizing coating 10, and gets back to original position.The rib portion (part of narrow that comprises adjacency between binding face 85b and binding face 85c) that thus, can avoid reliably cutting off sticking part 85 contacts ideal very with polarizing coating 10.
In addition, it is polyhedron-shaped cutting off sticking part 85, as shown in Figure 7, has the supporting surface of cut-out 85a, binding face 85b, 85c at its three masks, but also can have further the supporting surface of cut-out and/or binding face.For example, can be set forth in a mask has the formation of cutting off supporting surface, having binding face at three or four masks, and has at two masks the formation of cutting off supporting surface, having binding face at three or four masks.In addition, if as the cut-out sticking part 85 of Fig. 6, between binding face and cut off chamfering between supporting surface and binding face, and being formed with rib portion, from avoiding cutting off the viewpoint consideration that sticking part 85 contacts with polarizing coating, is more satisfactory.The size of cutting off sticking part 85 can suitably determine according to the width of polarizing coating 10, is not particularly limited, for example, the length more than can making 200mm and below 2000mm, the width more than 10mm and below 300mm.
Fig. 7 illustrates the stereographic map that cuts off sticking part 85.The state that Fig. 7 represents to make the cut-out sticking part 85 of Fig. 6 to turn clockwise after 1/3 week.As shown in Figure 7, cut off sticking part 85 and there is the cut-out supporting surface 85a that supports polarizing coating 10 along the Width of polarizing coating 10.Again, have the binding face 85b, the 85c that possess adsorbing mechanism 89,89 absorption of this adsorbing mechanism connect the connection material of polarizing coatings 10,20, to cover the cut-out line of the polarizing coating 10 being cut off.Also can make the formation with more than two binding face.
Cut off supporting surface 85a and be formed with the opening 86 of groove shape, be formed as the structure that the part of the sword of the set stapling machine 87 of the cut-out sticking part 85 shown in Fig. 6 can be passed through.By being formed with opening 86, can carry out reliably passing through of stapling machine 87 along the Width of polarizing coating 10, can carry out more accurately the connection of polarizing coating 10,20.
Stapling machine 87 can adopt known cutter, considers from the viewpoint that can easily cut off polarizing coating 10, more satisfactory for justifying bladed.Again, stapling machine 87 supports by the base portion 88 that can drive on the Width of polarizing coating 10.
Binding face 85b, 85c are mutual same formations, similarly have multiple adsorbing mechanisms 89 with adsorption section 84,84a.Again, dispose one side adhesive tape (connection material) 85d at binding face 85b, 85c, the non-surface of adherence of one side adhesive tape 85d keeps by adsorbing mechanism 89, and the surface of adherence of one side adhesive tape 85d is configured to the face contrary with binding face 85b, 85c.
As long as above-mentioned one side adhesive tape 85d can fit polarizing coating each other, can adopt known one side adhesive tape.As the membrane material of one side adhesive tape 85d, for example can enumerate polyethylene terephthalate film (PET film), cellulose, Japan paper, aluminium, nonwoven fabrics, teflon, Polyvinylchloride, polyvinylidene chloride, polycarbonate, polyurethane, ABS resin, polyester, polystyrene, tygon, polypropylene, poly-acetal resin, PLA, polyimide, polyamide etc.Again, the sticker using as adhesive phase, 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.
Film connecting portion 83 is configured to relative with polarizing coating 10.Therefore, in Fig. 5, due to polarizing coating 10 arranged perpendicular, therefore also arranged perpendicular of film connecting portion 83.On the other hand, also can make such structure, that is, and the in the situation that of such as vergence direction of polarizing coating 10 (or horizontal direction etc.) configuration, also vergence direction (or horizontal direction etc.) configuration of film connecting portion 83, to make film connecting portion 83 relative with polarizing coating 10.
Film connecting portion 93 is structures identical with film connecting portion 83.As shown in Figure 5, the adsorbing mechanism that film connecting portion 83,93 is configured to be arranged on the adsorption section on film connecting portion 83,93 toward each other.Again, film connecting portion 83,93 configures between the position of passing through of polarizing coating 10 and polarizing coating 20.In addition, the manufacturing system 100 with film connecting portion 83,93 is ideal forms of this example, also can make the form without film connecting portion 83,93.
(action of film connecting portion)
Below, the action of the manufacturing system to this example describes.In addition, about the explanation of this action is held concurrently as the explanation of the manufacture method of optical display.
First, as shown in Figure 1, unreel 1 from the 1st polarizing coating 10 is unreeled to (unreeling operation).Then, as shown in Figure 3, only polarizing coating 10a is carried out to hemisection by half not shown cutter, peel off stripping film 10b (stripping process) by the edge of a knife 4.Further, by niproll 6,6a, the polarizing coating 10a and the substrate 5 that have been stripped from stripping film 10b are carried out to crimping with fit (bonding process).In addition, the stripping film 10b being stripped from is batched, is reclaimed by not shown reeling end.By above-mentioned a series of operation, substrate 5 and polarizing coating 10a are fitted, and can obtain optical display.
In above-mentioned a series of operation, along with polarizing coating 10 is unreeled, be maintained at the 1st and unreel reducing around volume residual volume of polarizing coating 10 in portion 1.Below to polarizing coating connection operation connected to one another is described.
Connecting in operation, cut off the above-mentioned the 1st polarizing coating 10 and the 2nd that unreels portion 1 (11,1b) and unreel the polarizing coating 20 of the 1a of portion (11a, 1c).And, the 1st polarizing coating 10 and the 2nd that unreels portion 1 (11,1b) is unreeled to polarizing coating 10 or the 2nd that the 1st in the polarizing coating 20 of the 1a of portion (11a, 1c) unreel the production line side (ラ イ Application Side) of portion 1 (11,1b) unreels the polarizing coating 20 of the production line side of the 1a of portion (11a, 1c), the polarizing coating 10 that unreels the portion that the unreels side of portion 1 (11,1b) with the 2nd polarizing coating 20 or the 1st that unreels the portion that the unreels side of the 1a of portion (11a, 1c) is connected.Above-mentioned " production line side " in other words, is the direction that represents that polarizing coating is unreeled.As above-mentioned connection operation, can enumerate (1) by the method for operating personnel's method and (2) employing film connecting portion 83,93.
First, the method for passing through operating personnel of (1) is specifically described.In the situation that connecting two polarizing coatings by operating personnel, after the transporting velocity of polarizing coating 10 is made as to 0m/min (make polarizing coating 10 stop after), operating personnel cut off polarizing coating 10.Next, have for example to unreel the 1a of portion (11a, 1c) from the 2nd polarizing coating 20 is unreeled, after having cut off end, for example, adopt above-mentioned one side adhesive tape 85d to connect the method for polarizing coating.
Like this, in manufacturing system of the present invention, having the 1st unreels portion 1 (11,1b) and the 2nd and unreels two of the 1a of portion (11a, 1c) and unreel portion, even if the reel of polarizing coating is not exchanged for to new reel, also can adopt polarizing coating 10,20 to make immediately film connect, thereby can promptly unreel polarizing coating 20.Therefore, be only provided with 1 place to unreel the manufacturing system of portion different from existing, can carry out the replacing operation of polarizing coating volume to an on-stream idle side portion of unreeling, therefore can cut down the required time of operation of changing.Its result, can shorten the manufacturing time of optical display.In manufacturing system, after completing the connection of polarizing coating 10,20, during polarizing coating 20 is unreeled, be new reel by the 1st changing bobbins that unreels the polarizing coating 10 of portion 1.In the case of the surplus of polarizing coating 20 has reduced, can certainly similarly connect polarizing coating 20 and polarizing coating 10.
Next, utilize Fig. 8 to be specifically described the situation that adopts film connecting portion 83,93.Fig. 8 is the process chart that the connection operation of the manufacturing system with connecting portion is shown.When the surplus of polarizing coating 10 reduces, as shown in Fig. 8 (a), after the transporting velocity of polarizing coating 10 is made as to 0m/min, makes adsorption section 84,84a and cut off sticking part 85 (film connecting portion 83) and move to the vertical direction of polarizing coating 10.Next, adsorb polarizing coating 10 and be fixed (absorption process) by the adsorbing mechanism 89 of adsorption section 84,84a.
Now, the cut-out supporting surface 85a of cut-out sticking part 85 contacts with polarizing coating 10.Then, as shown in Fig. 8 (b), not shown stapling machine is moved along opening 86, and polarizing coating 10 is cut off to (cut-out operation).After cut-out, make to cut off sticking part 85 to vertical with polarizing coating 10 and mobile away from the direction (right side in figure) of polarizing coating 10, and make it be rotated counterclockwise 1/3 week, then it is mobile to direction (left side in figure) vertical with polarizing coating 10 and that approach polarizing coating 10 to make to cut off sticking part 85.Thus, as shown in Fig. 8 (c), with the state of cut-out line that covers the polarizing coating 10 relative with one side adhesive tape 85d (not shown) by the one side adhesive tape 85d of binding face 85b and polarizing coating 10 fit (bonding process).What above-mentioned cut-out line represented is the limit relative with binding face 85b in the section producing on polarizing coating 10 by cutting off operation.In bonding process, one side adhesive tape 85d is configured to cover above-mentioned cut-out line, that is, one side adhesive tape 85d crosses above-mentioned cut-out line, even if also configure in the part that does not have polarizing coating 10.
Further, for polarizing coating 20, with Fig. 8 (a)～(c) similarly one side adhesive tape 95d is adhered on the cut-out binding face 95b of polarizing coating 20.Give identical title to the member identical with above-mentioned member, the description thereof will be omitted.
First, unreel the 1a of portion (11a, 1c) from the 2nd polarizing coating 20 unreeled, with Fig. 8 (a) similarly, after having cut off the end of polarizing coating 20, not shown stapling machine is moved, to cut off polarizing coating 20 along being formed on the opening 96 cutting off on supporting surface 95a.After cut-out, make to cut off sticking part 95 to vertical with polarizing coating 20 and mobile away from the direction (left side in figure) of polarizing coating 20, and it is turned clockwise 1/3 week, then it is mobile to direction (right side in figure) vertical with polarizing coating 20 and that approach polarizing coating 20 to make to cut off sticking part 95.Thus, as shown in Fig. 8 (e), can stick one side adhesive tape 95d to cover the cut-out line of the polarizing coating 20 relative with the one side adhesive tape 95d of binding face 95b.
Next, as shown in Fig. 8 (f), make adsorption section 84,84a and cut off sticking part 85 (film coupling arrangement 3) approach adsorption section 94,94a and cut off sticking part 95 (film connecting portion 93), make the section of polarizing coating 10 and polarizing coating 20 be fitted to each other together (approaching operation).Thus, cover having crossed in one side adhesive tape 85d, the 95d of cut-out line of polarizing coating 10,20 and cut off the part of the line part of polarizing coating 10,20 laminatings (not with) and the opposing party's polarizing coating 20,10 laminatings, connect thus polarizing coating 10,20.In Fig. 8 (f), film connecting portion 83 is approached to film connecting portion 93, but also can make film connecting portion 93 approach to film connecting portion 83, can also make film connecting portion 83,93 close to each other.
After having connected polarizing coating 10,20, as preparatory process, as shown in Fig. 8 (g), make to cut off sticking part 85,95 respectively to vertical with polarizing coating 10,20 and move away from the direction of polarizing coating 10,20, make to cut off sticking part 85 and turn clockwise 1/3 week, make to cut off sticking part 95 and be rotated counterclockwise 1/3 week.And, make to cut off sticking part 85,95 respectively to vertical with polarizing coating 10,20 and move near the direction of polarizing coating 10,20.
Finally, make adsorption section 84,84a and cut off sticking part 85 (film connecting portion 83) to get back to the position of Fig. 8 (a), finish a series of operation.In addition, one side adhesive tape 85d, 95d are arranged on binding face 85c, 95c with the state being adsorbed in advance, therefore be arranged on the 1st at the reel of new polarizing coating 10 and unreel portion 1 (11,1b) afterwards, polarizing coating 20 is carried out to the operation of Fig. 8 (a)～(c), polarizing coating 10 is carried out to the operation of Fig. 8 (d)～(e), via the operation of Fig. 8 as described above (f)～(h), can make polarizing coating 20,10 connect.By supplementing the one side adhesive tape 85d, the 95d that use, can certainly connect continuously polarizing coating again.
As mentioned above, in the case of having used the connection operation of film connecting portion 83,93, compare with the operation that is connected of implementing by operating personnel, can and carry out more accurately absorption, cut-out, the laminating of polarizing coating within the shorter time, therefore comparatively desirable.
Specifically, in this manufacturing system, in the situation that implementing to connect operation by operating personnel, need about 10 minutes, but in the situation that using film connecting portion 83,93, can make to connect the needed time of operation below 1 minute.
In addition, in this manufacturing system, only using the 1st to unreel portion 1, do not use the 2nd to unreel the 1a of portion (11a, 1c), do not use in the situation of film connecting portion 83,93 yet, operating personnel need to change polarizing coating 10 after unreeling in portion 1 again new polarizing coating being changed to the 1st, therefore connect 30 points of left and right of operation needs.Therefore, the manufacturing system of this example is helpful is apparent.
< switching mechanism >
Switching mechanism 65 makes substrate 5 upsets of minor face or long edge person's throughput direction for growing limit or the minor face state along the throughput direction of the 2nd substrate carrying mechanism.That is, make surface and the back side upset of substrate 5, change along long limit and the minor face of the substrate 5 of throughput direction.First, adopt Fig. 9 to describe the structure of switching mechanism 65.
Fig. 9 is the stereographic map that switching mechanism 65 is shown, the action that makes the switching mechanism 65 in substrate 5 switching processes is shown.Switching mechanism 65 has the 66a of base plate supports portion, 66b, substrate overturn portion 67 and rotary shaft 68.Below, each member is described.
The 66a of base plate supports portion is the member of supporting substrate 5, can clamp loaded substrate 5.Be preferably the 66a of base plate supports portion and there is the absorbing unit that adsorbs substrate 5 again.As absorbing unit, can adopt known structure, for example, can adopt air to attract the absorbing unit of mode.In Fig. 9, the 66a of base plate supports portion is made up of arm and the absorbing unit of tubulose, be configured to the air attracting by absorbing unit by the structure in arm, but the shape of arm and absorbing unit is not limited to this formation.
Again, the structure of the 66a of base plate supports portion is, has two absorbing units on arm, has 1 couple of arm group who is made up of three arms.Again, absorbing unit disposes 4 on the diagonal line of substrate 5, on the length direction of substrate 5, is also provided with two absorbing units between above-mentioned absorbing unit.The number of elements of this arm and the magnitude setting of absorbing unit are an example eventually, for example,, large substrate overturn, can suitably change in the case of making, for example, increase the number of elements of arm and the quantity of absorbing unit etc.Again, can certainly change, for example, make the set-up site of absorbing unit concentrate on the core of substrate 5, or change to the end periphery of substrate 5.
In the situation that the 66a of base plate supports portion does not load substrate 5, the extended distance between arm group state to can receive substrate 5 (following, this state is called to " holding state ").On the other hand, the extended distance of the 66b of base plate supports portion between arm group state, to can receive substrate 5, there is the structure identical with the 66a of base plate supports portion.Because a pair of arm group clamps substrate 5, therefore can make the distance constriction between arm group again.Like this, the distance between arm group can change, and therefore, the 66a of base plate supports portion, 66b are configured to, and have motor, and rotatablely moving of motor changed into rectilinear motion to change the distance between arm group.In addition, as long as changing the formation of the distance between arm group, also can change the formation with motor and use.
Substrate overturn portion 67 is connected to the 66a of base plate supports portion, 66b, by rotation centered by trip shaft M, substrate 5 is overturn.In Fig. 9, substrate overturn portion 67 is connected with each arm, considers from lightweight and the viewpoint that alleviates the air resistance in when rotation, is preferably the structure of tubulose.But, be not limited to this structure.For example, also can adopt the tabular tubulose that replaces.
Substrate overturn portion 67 rotates centered by trip shaft M.As the member that substrate overturn portion 67 is rotated, there is for example the driver element that adopts motor.In Fig. 9 (a), as preferred form, substrate overturn portion 67 has rotary shaft 68.Rotary shaft 68, along trip shaft M configuration, therefore can stably rotate along trip shaft M.In this example, substrate overturn portion 67 is structures of rotation together with rotary shaft 68, is that substrate overturn portion 67 is easy to the structure of stably rotating centered by trip shaft M.Therefore, having the substrate overturn portion 67 of rotary shaft 68 can be along the more stable rotation of trip shaft M.Therefore, can the more stable upset of carrying out substrate 5.In addition, rotary shaft 68 can rotate towards surface direction with respect to the substrate 5 before upset, also can be on the contrary towards back side direction rotation.
As shown in Fig. 9 (a), trip shaft M is positioned at following plane, in this plane " contain with respect to center and the straight line vertical with the throughput direction D1 of aforesaid substrate 5 of the substrate 5 before the upset by the 1st substrate carrying mechanism and there is the straight line of 45 ° of degree of tilt, and substrate 5 before the upset that contains the 1st substrate carrying mechanism ".Above-mentioned have the straight line of 45 ° of degree of tilt for the straight line of the trip shaft M along Fig. 9 (a).Again, the plane of " substrate 5 before the upset that contains the 1st substrate carrying mechanism " mean with upset before substrate 5 be same level, in Fig. 9 (a), be the plane that is positioned at X-Y plane.
In Fig. 9, the example that the 66a of base plate supports portion, 66b, substrate overturn portion 67 and rotary shaft 68 are formed is respectively illustrated, as long as still have the function of each member, the member that can certainly serve as one forms.
Next, the action of switching mechanism 65 is described.In Fig. 9, the throughput direction D1 to the minor face of substrate 5 along the 1st substrate carrying mechanism, the situation that the long edge that makes substrate 5 overturn to become substrate 5 state of the throughput direction D2 of the 2nd substrate carrying mechanism describes.But, substrate 5 to throughput direction D1 by long edge, overturn for minor face be passable too along the state of throughput direction D2.
Fig. 9 (w1) is the stereographic map that the switching mechanism 65 of holding state is shown.As shown in the drawing, the 66a of base plate supports portion becomes and widens 1 pair of distance between arm group to accept the state of substrate 5.On the other hand, the 66b of base plate supports portion is configured in the position that substrate 5 is reversed, due to overturn substrate 5 is liberated, so the distance between 1 couple of arm group that base plate supports 66b possesses is also the state of widening.
Along the throughput direction D1 of X-Y plane, during to the 66a of base plate supports portion carrying substrate 5, substrate 5 is positioned on the 66a of base plate supports portion.Specifically, substrate 5 moves between arm group, and substrate 5 is positioned on the arm group of below of the 66a of base plate supports portion.Whether substrate 5 is positioned on arm group is confirmed that by substrate sensor judges.In this example, substrate confirms that sensor is configured to and is arranged at respectively the 66a of base plate supports portion and the 66b of base plate supports portion, as long as but be arranged on the position of the mounting that can confirm substrate 5, also can be arranged on the place beyond this position.
Then, the confirmation signal of substrate 5 confirms that from substrate sensor sends to arm group, and as shown in Fig. 9 (a), arm group is close with clamping substrate 5 each other.Further, thus adsorb the surface fixing base 5 further of substrate 5 by absorbing unit.Like this, by the absorption of absorbing unit, and only clamp compared with the situation of substrate 5 fixing base 5 further with arm group.Thus, can avoid substrate 5 to come off when rotated.
Next, rotary shaft 68 rotates centered by trip shaft M, and substrate overturn portion 67 also rotates to the surface direction of substrate 5 together thus.Fig. 9 (b) represents the state of substrate overturn portion 67 from the state of Fig. 9 (a) has rotated 90 ° centered by trip shaft M.In Fig. 9 (b), substrate 5 is positioned at the position along Z-direction.Now, the 66b of base plate supports portion does not clamp substrate 5, is rotated down 90 ° along with the rotation of substrate overturn portion 67.
Further, substrate overturn portion 67 together with rotary shaft 68 centered by trip shaft M half-twist, substrate 5 is turned to the position with respect to trip shaft M line symmetry thus.In addition, although not shown, the end of the substrate 5 of throughput direction D2 side is positioned on the transfer roller of the 2nd substrate carrying mechanism.This state is shown in Fig. 9 (c).Like this, as shown in Fig. 9 (a)～(c), the long edge of substrate 5 throughput direction and the minor face of substrate and is exchanged between the throughput direction of substrate, and has carried out the upset at surface and the back side of substrate.Therefore, can be by niproll 16,16a from lower surface with the orthogonal mode of its absorption axes polarizing coating of fitting.Again, the semi-circular track of 180 ° is depicted in the action of switching mechanism 65 centered by trip shaft M, does not need to carry out complicated action.Therefore, can a substrate 5 be overturn with shorter pitch time.
Further, the 66a of base plate supports portion, 66b are line with respect to trip shaft M and are provided with symmetrically a pair of.Therefore,, while substrate 5 being overturn by the 66a of base plate supports portion, the 66b of another base plate supports portion is moved to the position at substrate 5 places before the upset in Fig. 9 (a).
Status releasing in the absorption of the absorbing unit of the 66a of base plate supports portion from Fig. 9 (c), when the distance between arm group is widened, substrate 5 is positioned on the arm group of the below in a pair of arm group.Then,, as shown in Fig. 9 (w2), substrate 5 is along with the rotation of the transfer roller that the 2nd substrate carrying mechanism has is transferred to throughput direction D2.
Here, the 66b of base plate supports portion moves to the position of the substrate 5 before upset.Thus, need not wait for the Move that moves of the 66a of base plate supports portion, the substrate 5 ' reversion that just can promptly make the next one be transferred.That is, adopt laminating apparatus 60, the upset of carrying out 1 substrate is certain, can also reduce the time loading after making substrate overturn till next substrate.Its result, can process multiple substrates successively with shorter pitch time.
