Below the action of the manufacturing installation 20 of formation like this is described, carry out following explanation in the mode that is associated with substrate heating method of the present invention.
At first, photonasty plate 22a, 22b send from each photonasty plate roller 23a, the 23b that is installed on the 1st and the 2nd plate delivering mechanism 32a, the 32b.Photonasty plate 22a, 22b conveyance to the 1 and the 2nd organisation of working 36a, 36b.
In the 1st and the 2nd organisation of working 36a, 36b; circle sword 52 moves at the Width of photonasty plate 22a, 22b; begin described photonasty plate 22a, 22b are cut from diaphragm 30,, form hemisect position 34 (with reference to Fig. 2) up to incision photo-sensitive resin 28 and even basement membrane 26.And then, as shown in Figure 1,, stop after the direction conveyance in arrow A in the size of the remnant 30b of corresponding diaphragm 30 for photonasty plate 22a, 22b, under the motion effect of circle sword 52, form hemisect position 34.Thus, on photonasty plate 22a, 22b,, the place ahead released part 30aa and rear released part 30ab (with reference to Fig. 2) are set according to the mode of clamping remnant 30b.
Next, each photonasty plate 22a, 22b conveyance to the 1 and the 2nd label bonding agency 40a, 40b are located at the regulation sticking position of diaphragm 30 and bear on the platform 56.In the 1st and the 2nd label bonding agency 40a, 40b; the adhesive labels 38 of regulation sheet number be adsorbed the pad 54a~54g adsorb maintenance, each adhesive labels 38 stride diaphragm 30 remnant 30b and with the place ahead released part 30aa and rear released part 30ab one bonding (with reference to Fig. 3).
As shown in Figure 1, for the photonasty plate 22a, the 22b that are bonded with 7 adhesive labels 38, after preventing to send the tension change of side by the 1st and the 2nd 42a of reservoir mechanism, 42b, conveyance to the 1 and the 2nd mechanism for stripping 44a, 44b continuously.As shown in Figure 6, in the 1st and the 2nd mechanism for stripping 44a, 44b, 26 absorption of the basement membrane of photonasty plate 22a, 22b remain in and suck on the tube 62, and diaphragm 30 is reserved remnant 30b and peeled off from described photonasty plate 22a, 22b.This diaphragm 30 is stripped from roller 63 and is peeled off, and is wound in the diaphragm coiling portion 64 (with reference to Fig. 1).
Under the effect of the 1st and the 2nd mechanism for stripping 44a, 44b; diaphragm 30 is reserved remnant 30b and after peeling off from basement membrane 26; photonasty plate 22a, 22b carry out tension adjustment by the 1st and the 2nd tension control mechanism 66a, 66b; and then; in the 1st and the 2nd 47a of testing agency, 47b, carry out the detection at hemisect position 34 by photoelectric sensor 72a, 72b.
Each photonasty plate 22a, 22b be based on the detection information at hemisect position 34, under the turning effort of film carrying roller 90a, 90b, respectively quantitatively conveyance to attaching mechanism 46.
On the other hand, as shown in Figure 4, in lining heat 45, corresponding attach the laminating temperature in the mechanism 46 and set furnace atmosphere temperature in the 1st~the 5th heating furnace 82~90.For example, if laminating temperature is 110 ℃, then the furnace atmosphere temperature in the 1st heating furnace the 82, the 2nd heating furnace the 84, the 3rd heating furnace the 86, the 4th heating furnace 88 and the 5th heating furnace 90 is set at respectively about 150 ℃, 140 ℃, 135 ℃, 135 ℃ and 135 ℃.In addition, in glass substrate 24, coat the quality that modifying agent is connected airtight on lip-deep surface in order to keep, ceiling temperature is set at 130 ℃.
Then, the glass substrate 24 that is contained in the substrate stocker 120 is controlled by robot 122, and this glass substrate 24 is sent into acceptance division 78.In acceptance division 78, in glass substrate 24 and after the posture rotation with expectation, from described acceptance division 78 off and among conveyance to the 1 heating furnace 82 by universal stage 80.
In the 1st heating furnace 82, after glass substrate 24 heated up because of the heat effect of the 1st well heater 94a is rapid, glass substrate 24 is conveyance to the 2 heating furnaces 84 by the carrying roller 76a that constitutes transport mechanism 74.On the other hand, the new glass substrate of sending in the acceptance division 78 24 is sent in the 1st heating furnace 82.
In the 2nd heating furnace 84, after glass substrate 24 heated up by the 2nd well heater 94b, described glass substrate 24 is conveyance to the 3 heating furnaces 86 by the carrying roller 76b that constitutes transport mechanism 74.Conveyance to the 4 heating furnaces 88 carry out hyperthermic treatment and localization process by the 4th heating furnace 88 by the carrying roller 76c that constitutes transport mechanism 74 by the glass substrate 24 after 86 intensifications of the 3rd heating furnace.
Be provided with detent mechanism 92 in the 4th heating furnace 88, as shown in Figure 5, at first, shown in solid line, Width alignment roller 108a, 108b are configured on arrow D direction away from each other, and under this state, under the driving action of working cylinder 98, lifting table 100 rises.
On this lifting table 100, be provided with supporting station 104 by guide rod 102a, 102b, and, on described supporting station 104, be arranged with a plurality of positioning elements 106.Therefore, the glass substrate 24 on the carrying roller 76d is located in positioning element 106 supportings, will shift the top of described carrying roller 76d on this glass substrate 24 onto.
Then, the motor 112a, the 112b that constitute driving and reversing mechanism 110a, 110b drive, movable pillar 118a, the 118b displacement on approximating direction by screw axis 114a, 114b and nut portions 116a, 116b.Therefore, the Width alignment roller 108a, the 108b that are installed on movable pillar 118a, 118b top move on approximating direction, with the arrow D direction both ends butt that is supported on the glass substrate 24 on the positioning element 106, thereby carry out the location of this glass substrate 24.
After glass substrate 24 positioned, after the both ends of this glass substrate 24 were left slightly, lifting table 100 descended by working cylinder 98 at Width alignment roller 108a, 108b.Then, the glass substrate 24 that is supported on the positioning element 106 joins on a plurality of carrying roller 76d from this positioning element 106, and on the other hand, Width alignment roller 108a, 108b move in away from each other direction by driving and reversing mechanism 110a, 110b.In addition, carry out the Width alignment under the state that Width alignment roller 108a, 108b also can also leave slightly at the width than glass substrate 24.
Like this, when stopping to descend at glass substrate 24 contact carrying roller 76d, Width alignment roller 108a, 108b and this glass substrate 24 butts and the damage that can prevent to produce dust or glass substrate 24.
And positioning element 106 is formed by the material that can produce frictional resistance.Therefore, when positioning element 106 descends, can prevent the offset of glass substrate 24 well.
Join in the glass substrate on the carrying roller 76d 24 under the turning effort of this carrying roller 76d, be incubated processing in conveyance to the 5 heating furnaces 90, be heated under the state of set point of temperature conveyance to sticking position.This glass substrate 24 temporarily is positioned between rubber rollers 130a, the 130b corresponding to the attaching part of the photo-sensitive resin 28 of photonasty plate 22a, 22b arranged side by side.
Under this state, backing roll 132b and rubber rollers 130b are risen, thereby glass substrate 24 sandwich between rubber rollers 130a, the 130b with the regulation pressing force.And under the turning effort of rubber rollers 130a, photo-sensitive resin 28 transfer printings (lamination) arranged side by side are to this glass substrate 24.
Here, as lamination, speed is 1.0m/min~10.0m/min, and the temperature of rubber rollers 130a, 130b is 80 ℃~150 ℃, the rubber hardness of described rubber rollers 130a, 130b is 40 degree~90 degree, and the pressing force (line pressure) of this rubber rollers 130a, 130b is 50N/cm~400N/cm.
If the lamination of photonasty plate 22a, the 22b of lamination a slice amount end on glass substrate 24 by rubber rollers 130a, 130b, then the rotation of described rubber rollers 130a stops, on the other hand, lamination has the described glass substrate of described photonasty plate 22a, 22b promptly to attach substrate 24a by 142 clampings of substrate conveyance roller.
Then, rubber rollers 130b keeps out of the way in the direction of leaving rubber rollers 130a, clamp thereby remove, and the rotation of beginning substrate conveyance roller 142, attach substrate 24a quantitatively conveyance on the direction of arrow C, the position moves near the assigned position in below of rubber rollers 130a between the substrate of photonasty plate 22a, 22b.On the other hand, by substrate conveyance mechanism 45, next piece glass substrate 24 conveyance is to sticking position.
If the front end conveyance of this next piece glass substrate 24 is between rubber rollers 130a, the 130b, then described rubber rollers 130b rises, and described next piece glass substrate 24 and photonasty plate 22a, 22b are clamped by described rubber rollers 130a, 130b.Then, under the turning effort of rubber rollers 130a, 130b and substrate conveyance roller 142, begin lamination, and attach substrate 24a in the conveyance of arrow C direction.
At this moment, as shown in Figure 7, attach each end of substrate 24a and cover by remnant 30b each other.Therefore, when photo-sensitive resin 28 was transferred on the glass substrate 24, rubber rollers 130a, 130b can not polluted by described photo-sensitive resin 28.
After the attaching substrate 24a that is attached mechanism's 46 laminations cools off by cooling body 144, be transferred to prestripping portion 148.In this prestripping portion 148, peel strip 156 rises, and diaphragm 30 can be peeled off from the rear end and the front end of the glass substrate 24 of adjacency thus.Then, in the automatic mechanism for stripping 146 of substrate, under the turning effort of wireline reel 152, basement membrane 26 is reeled continuously from attaching on the substrate 24a.
The glass substrate 24 that peels off basement membrane 26 is disposed at the inspection station of corresponding analyzer 158.Check station at this, under the state of glass substrate 24 positioning and fixing, adopt video camera 160 to read the image of glass substrate 24 and photo-sensitive resin 28.Then,, calculate sticking position, and detect the attaching state by carrying out Flame Image Process.
In addition, for example photonasty plate roller 23a, 23b are being carried out exchanging operation or to being wound in basement membrane 26 on the wireline reel 152 when taking out operation etc., glass substrate 24 is stranded in the 1st heating furnace 82~the 5th heating furnace 90 that constitutes lining heat 45, and the driving of carrying roller 76a~76e stops.
And the carrying roller 76a in for example being judged to be the 1st heating furnace 82 exceeds setting-up time and when stopping, described carrying roller 76a rotation is driven.At this moment, when glass substrate 24 mountings are on carrying roller 76a, each carrying roller 76a is back and forth rotated and make described glass substrate 24 in the 1st heating furnace 82, move back and forth (with reference to Fig. 4).
Specifically, each carrying roller 76a rotates 0.5 respectively by clockwise (positive axis) and counterclockwise (contrary axle) changes~1.5 commentaries on classics, preferably rotates respectively more than 1 commentaries on classics.
On the other hand, when on carrying roller 76a, not having glass substrate 24, described carrying roller 76a one direction is rotated continuously.Therefore, the carrying roller 76a in the 1st heating furnace 82 can not be heated from the top by the 1st well heater 94a above setting-up time under the state that rotation stops.Therefore, can stop reliably owing to the one-sided overheated thermal deformation that produces of the upper side of carrying roller 76a.
Thus, also can only make carrying roller 76a carry out direction rotation or back and forth rotation, can prevent that carrying roller 76a from producing whirling with simple operation.Therefore, can access well and to stop because the conveyance of glass substrate 24 is crooked or shake the damage that causes or owing to such effects such as stopping of causing of conveyance fault.
In addition, in the 2nd heating furnace 84~the 4th heating furnace 88, also the same with described the 1st heating furnace 82, carry out direction rotation or back and forth rotation by making described carrying roller 76b~76d, thereby can prevent that described carrying roller 76b~76d from heating above setting-up time under the state that rotation stops.
And then, as shown in Figure 5, in the 5th heating furnace 90, but have the positioning element 106 of free lifting by working cylinder 98.Like this, the glass substrate 24 on the carrying roller 76e is carried out a direction and is rotated continuously after joining on this positioning element 106 by positioning element 106 risings.Like this, carrying roller 76e can not surpass setting-up time and heat under the state that stops, can obtaining the same effect with described carrying roller 76a.
Yet, because plant failure, the cleaning of rubber rollers 130a, 130b, the replacing of described rubber rollers 130a, 130b or the fault of upstream and downstream operation etc., when lamination treatment stopped than the long certain hour of described setting-up time for example more than 1 hour, the 1st well heater 94a~the 5th well heater 94e that constitutes lining heat 45 closed.Then, when lamination treatment begins once more, before the conveyance of glass substrate 24 begins, make the 1st well heater 94a~the 5th well heater 94e open-minded, and make the carrying roller 76a~76e that constitutes transport mechanism 74 temporarily carry out direction rotation or back and forth rotation, will be heated to set point of temperature respectively in the 1st heating furnace 82~the 5th heating furnace 90 simultaneously.
Therefore, when glass substrate 24 conveyances begin, can be in each carrying roller 76a~76e owing to the one-sided overheated thermal deformation that causes.Therefore, have conveyance glass substrate well 24, effectively carry out the such advantage of lamination treatment.
In addition, in the 1st embodiment,, be not limited only to this, also can adopt 1 photonasty plate roller or the photonasty plate roller more than 3 although adopt 2 photonasty plate roller 23a, 23b.In addition, in the 2nd embodiment that the following describes too.
Fig. 8 is the summary construction diagram of manufacturing installation 300 of the light-sensitive layers body of the 2nd embodiment of the present invention.Adopt identical Reference numeral for the component parts identical, and omit its detailed description with the manufacturing installation 20 of the 1st embodiment.
Manufacturing installation 300 is disposed at the downstream that attaches mechanism 46, and having can be with plate shut-off mechanism 48 between the photonasty plate 22a between each glass substrate 24, substrate that 22b cuts off integratedly.
In the manufacturing installation 300 that so constitutes, the same with described the 1st embodiment, by the attaching substrate 24a conveyance on the arrow C direction that attaches mechanism's 46 laminations.Then, if attach the position that arrives plate shut-off mechanism 48 between corresponding substrate between substrate 24a, then plate shut-off mechanism 48 is rolled up photonasty plate 22a, 22b with 2 simultaneously and is cut off integratedly to move on the arrow C direction with the same conveyance speed of described attaching substrate 24a between this substrate between this attachings substrate 24a.
After this cut off, plate shut-off mechanism 48 turned back to the position of readiness of regulation between substrate, in attaching substrate 24a, basement membrane 26 and remnant 30b was peeled off successively that (the sheet leaf is peeled off (Mei Leaf stripping
)) and produce light-sensitive layers body 208.
