The present invention provides an apparatus and a manufacturing apparatus for a photosensitive laminate which manufactures a photosensitive laminate by sending a long photosensitive web having a photosensitive material layer formed on a substrate and a support between a pair of pressing rollers and attaching the photosensitive material layer to the substrate. It is about a method.

For example, the photosensitive sheet body (photosensitive web) which has a photosensitive resin layer (photosensitive material layer) is attached to the board | substrate surface to the board | substrate for liquid crystal panels, the board for printed wirings, and the board | substrate for PDP. As for the photosensitive sheet body, the photosensitive resin layer and the protective film are laminated | stacked sequentially on the flexible plastic support body.

The manufacturing apparatus used for the attachment of this kind of photosensitive sheet body is usually carried out by transferring a substrate such as a glass substrate or a resin substrate at predetermined intervals, and in response to the range of the photosensitive resin layer attached to the substrate. The method of peeling off a protective film is employ | adopted.

For example, in the manufacturing apparatus disclosed in Unexamined-Japanese-Patent No. 11-34280, as shown in FIG. 9, the laminated | multilayer film (photosensitive sheet | seat) 1a unwound from the film roll 1 is guide roller 2a, It is wound around 2b) and extended along the horizontal film conveyance surface. The rotary roller 3 which outputs the pulse signal of the number according to the feeding amount of the laminated body film 1a is attached to this guide roller 2b.

The laminated film 1a extending along the horizontal film conveying surface is wound around the suction roller 4 and the half cutter device 5 and the cover film between the guide roller 2b and the suction roller 4. The peeling apparatus 6 is provided.

The half cutter apparatus 5 is equipped with one pair of disk cutters 5a and 5b which spaced apart a predetermined space | interval in the conveyance direction of the laminated body film 1a. The disk cutters 5a and 5b move along the film width direction of the laminate film 1a so that two boundary portions of the peeling portion and the remaining portion in the cover film (not shown) of the laminate film 1a are shown. Is cut | disconnected integrally with the photosensitive resin layer (not shown) of the back surface side.

The cover film peeling apparatus 6 strongly presses the adhesive tape 7a released from the adhesive tape roll 7 to the peeling part of the cover film between the pressing rollers 8a and 8b, and then a winding roll 9 Winding by). Thereby, the peeling part of a cover film is peeled from the photosensitive resin layer, and is wound to the winding roll 9 with the adhesive tape 7a.

Downstream of the suction roller 4, a pair of crimping | compression-bonding the peeling part of the laminated | multilayer film 1a which the cover film peeled on the upper surface of the some board | substrate 11 conveyed by the board | substrate conveying apparatus 10 at predetermined intervals is crimped | bonded. Lamination rollers 12a and 12b are arranged. The support film winding roll 13 is arrange | positioned downstream of these lamination rollers 12a and 12b. The translucent support film (not shown) attached to the board | substrate 11 is wound by the support film winding roll 13 with the remaining part of a cover film in the state which remained the photosensitive resin layer on the board | substrate 11.

By the way, in order to adhere | attach the peeling part of the laminated | multilayer film 1a with which the cover film was peeled off to the desired range of the board | substrate 11 correctly, the laminated | multilayer film 1a based on the boundary part of the peeling part and remaining part of a cover film as a reference | standard. Needs to be sent out between the lamination rollers 12a and 12b with high accuracy.

In addition, since the lamination rollers 12a and 12b are attached while the laminate film 1a and the substrate 11 are heated, the extension of the laminate film 1a becomes particularly large in the vicinity of the lamination rollers 12a and 12b. Throw it away.

In this case, if the position of the said boundary part of the said laminated body film 1a can be detected between lamination rollers 12a and 12b, the position can be adjusted and a high precision adhesion process can be performed. However, detecting the position of the boundary portion while sandwiching the laminate film 1a and the substrate 11 with the lamination rollers 12a and 12b is practically impossible because the lamination rollers 12a and 12b inhibit the detection.

Therefore, the sensor which detects the said boundary part is arrange | positioned in the predetermined site | part between the suction roller 4 and the lamination rollers 12a, 12b, and the delivery amount of the laminated | multilayer film 1a from the time when this sensor detected the boundary part. The manufacturing apparatus which controlled this is proposed by this applicant (refer Unexamined-Japanese-Patent No. 2006-297889).

In this case, knowing the distance between the sensor and the lamination rollers 12a and 12b and the elongation of the laminate film 1a therebetween, the boundary between the laminations 12a and 12b is set with high accuracy. Can be.

However, although the sensor can detect the boundary portion, it is not able to detect how far the boundary portion deviates from the desired position.

The half cutter control unit 108 may determine that the position shift amount? La,? Lb or? Ma,? Mb of the half cut portion 34 calculated by the position shift amount calculation unit 120 exceeds a predetermined allowable amount. At this time, the half cut position which corrects the position of the half cut part 34 by the 1st and 2nd processing mechanisms 36a and 36b based on the said position shift amount (DELTA) La, (DELTA) L, or (DELTA) Ma and (DELTA) Mb. It has a correction unit 128.

The manufacturing apparatus 20 is partitioned into the first clean room 112a and the second clean room 112b through the partition wall 110. The first clean room 112a accommodates the first and second web delivery mechanisms 32a and 32b to the first and second tension control mechanisms 66a and 66b, and the second clean room 112b includes a first clean room 112b. After the first and second detection mechanisms 47a and 47b are accommodated. The first clean room 112a and the second clean room 112b communicate with each other through the through part 114.

The operation of the manufacturing apparatus 20 configured as described above will be described below with respect to the manufacturing method according to the present invention.

First, the photosensitive webs 22a and 22b are sent out from the photosensitive web rolls 23a and 23b attached to the first and second web delivery mechanisms 32a and 32b. The photosensitive webs 22a and 22b are conveyed to the first and second processing mechanisms 36a and 36b.

In the first and second processing mechanisms 36a and 36b, the round blade 52 moves in the width direction of the photosensitive webs 22a and 22b to move the photosensitive webs 22a and 22b from the protective film 30 to the photosensitive resin layer. Half cut portions 34 are formed by cutting from 28 to base film 26 (see Fig. 2). In addition, the photosensitive webs 22a and 22b are stopped after being conveyed in the direction of the arrow A corresponding to the width M of the remaining portion 30b of the protective film 30, and are half under the running action of the round blade 52. The cut portion 34 is formed. Accordingly, the front peeling part 30aa and the rear peeling part 30ab are formed in the photosensitive webs 22a and 22b with the remaining part 30b interposed therebetween (see FIG. 2).

In addition, the width M of the remaining portion 30b is provided with the glass substrate 24 supplied between the rubber rollers 80a and 80b of the attachment mechanism 46 on the premise that the photosensitive webs 22a and 22b do not extend. It shall be set based on the distance between them. Further, the pair of half cut portions 34 formed in the width M are formed on the long photosensitive webs 22a and 22b at intervals of the reference length L of the photosensitive resin layer 28 attached to the glass substrate 24. Is formed.

Subsequently, each photosensitive web 22a, 22b is conveyed to the 1st and 2nd label adhesion mechanism 40a, 40b, and the predetermined | prescribed attachment site of the protective film 30 is arrange | positioned on the base 56. As shown in FIG. In the first and second label adhesive mechanisms 40a and 40b, a predetermined number of adhesive labels 38 are adsorbed and held by the adsorption pads 54b to 54g, and each adhesive label 38 remains in the protective film 30. Over the part 30b, it adheres integrally to the front peeling part 30aa and the rear peeling part 30ab (refer FIG. 3).

For example, the photosensitive webs 22a and 22b to which the seven adhesive labels 38 are adhered prevent the tension variation on the sending side through the first and second reservoir mechanisms 42a and 42b as shown in FIG. Then, it is conveyed continuously to the 1st and 2nd peeling mechanism 44a, 44b. In the first and second peeling mechanisms 44a and 44b, the base film 26 of the photosensitive webs 22a and 22b is adsorbed and supported by the suction drum 62, and the protective film 30 provides the remaining portion 30b. Leaving and peeling from the photosensitive webs 22a and 22b. This protective film 30 is peeled off through the peeling roller 63 and is wound on the protective film winding part 64 (refer FIG. 1).

Under the action of the first and second peeling mechanisms 44a and 44b, after the protective film 30 is peeled off from the base film 26 leaving the remaining portion 30b, the photosensitive webs 22a and 22b are first and secondly formed. Tension adjustment is performed by the two tension control mechanisms 66a and 66b, and then the half cut portion 34 is detected by the first and second detection mechanisms 47a and 47b.

Illumination light, which is red light, is irradiated from the two-dimensional light sources 69a and 69b constituting the first and second detection mechanisms 47a and 47b to the long photosensitive webs 22a and 22b, and the transmitted light is guided to the CCD cameras 72a and 72b. As a result, images of the long photosensitive webs 22a and 22b including the half cut portions 34 and images of the reference pieces 67a and 67b disposed at the reference position are picked up. In addition, since the half cut part 34 is formed in the state which removed the photosensitive resin layer 28 from the long photosensitive webs 22a and 22b, the image of the half cut part 34 with high luminance is obtained. The position shift amount calculation unit 120 calculates the position shift amounts? La and? Lb of the half cut portions 34 with respect to the tip portions of the reference pieces 67a and 67b based on the picked-up image.

In this case, the half cut part 34 on the peeling part 30aa side shown in FIG. 2 and the front-end | tip part of the reference piece 67a, 67b match, and the position shift amount ((DELTA) La, (DELTA) Lb) is 0, and a rubber roller is used. Reference length between the first and second detection mechanisms 47a and 47b and the attachment mechanism 46 such that the half cut portion 34 on the peeling portion 30ab side preceding the predetermined position between the 80a and 80b is disposed. It is assumed that (L) is set.

Therefore, from the above state, the photosensitive webs 22a and 22b are conveyed and stopped by the distance corresponding to the width M of the remaining portion 30b of the protective film 30, and the glass substrate 24 is transported. It conveys to an attachment position in the state heated beforehand under the effect of (45). The glass substrate 24 is once arrange | positioned between the rubber rollers 80a and 80b corresponding to the attachment part of the photosensitive resin layer 28 of the photosensitive webs 22a and 22b which are parallel.

Then, the glass substrate 24 is sandwiched between the rubber rollers 80a and 80b at a predetermined press pressure by raising the backup roller 82b and the rubber roller 80b. The roller control unit 126 (FIG. 6) drives the roller drive motor 124 on the basis of the laminate control pulses corresponding to the uncorrected reference length L supplied from the control pulse correction unit 123 to form a rubber roller ( The photosensitive webs 22a and 22b and the glass substrate 24 are conveyed in the direction of an arrow C under the rotational action of 80a. As a result, each photosensitive resin layer 28 in parallel is melted by heat, and is transferred (laminated) to the glass substrate 24. In this case, if there is no extension in the photosensitive webs 22a and 22b, the photosensitive resin layer 28 of the photosensitive webs 22a and 22b will be moved from the half cut portion 34 on the back peeling part 30ab side to the glass substrate 24. It is accurately transferred to a predetermined portion of the).

In addition, as lamination conditions, the speed is 1.0 m / min-10.0 m / min, the temperature of the rubber rollers 80a, 80b is 80 degreeC-150 degreeC, and the rubber hardness of the said rubber rollers 80a, 80b is 40 degrees-90 degrees. The press pressure (linear pressure) of the rubber rollers 80a and 80b is 50 N / cm to 400 N / cm.

When the substrate tip detection sensor 94 detects the tip of the glass substrate 24 and the lamination of one sheet of the photosensitive webs 22a and 22b is finished on the glass substrate 24 through the rubber rollers 80a and 80b, While the rotation of the rubber roller 80a is stopped, the glass substrate 24 (hereinafter also referred to as the attachment substrate 24a) on which the photosensitive webs 22a and 22b are laminated is formed by the substrate conveying roller 92. Clamped.

Then, the rubber roller 80b retracts in the direction away from the rubber roller 80a, the clamp is released, and the rotation of the substrate transfer roller 92 is started to protect the attached substrate 24a in the direction indicated by the arrow C. It is conveyed by the distance corresponding to the width | variety M of the residual part 30b of the film 30, and the half cut part 34 of the peeling part 30ab side of the protective film 30 back is lower than the rubber roller 80a. Move to a predetermined position in the vicinity. On the other hand, the next glass substrate 24 is conveyed toward an attachment position through the board | substrate conveyance mechanism 45. As shown in FIG. By repeating the above operation, the attachment substrate 24a is continuously manufactured.

In that case, as shown in FIG. 4, each edge part is covered with the remaining part 30b as shown in FIG. Therefore, when the photosensitive resin layer 28 is transferred to the glass substrate 24, the rubber rollers 80a and 80b do not become dirty by the said photosensitive resin layer 28. FIG.

The attachment substrate 24a laminated by the attachment mechanism 46 is cooled through the cooling mechanism 122, and then transferred to the free peeling part 144. In this free peeling part 144, the peeling bar 156 temporarily enters and rises between the glass substrates 24, and by this, the protective film 30 between the glass substrates 24 is lifted, and it adjoins, It peels from the rear end and the front end of the glass substrate 24. FIG.

Subsequently, in the base automatic peeling mechanism 142, the base film 26 is continuously wound from the attachment substrate 24a under the rotational action of the winding shaft 148. In addition, after the separation at the trouble stop or the cutting at the time of defective product separation, the base film 26 tip of the base film 26 of the attached substrate 24a where the lamination treatment is newly started and the base film 26 wound on the winding shaft 148 The rear end is automatically attached through the automatic attacher 150.

The attachment substrate 24a from which the base film 26 has been peeled off is disposed at the inspection station corresponding to the measuring device 158. In this inspection station, the images of the glass substrate 24 and the photosensitive resin layer 28 are received by the four cameras 160 in the state where the glass substrate 24 was positioned and fixed. The attachment position is calculated by performing image processing.

The attachment substrate 24a whose attachment position of the photosensitive resin layer 28 was confirmed is taken out by the robot 134, and is accommodated in the photosensitive laminated body stocker 132 as the photosensitive laminated body 106. As shown in FIG.

By the way, in the above description, it is assumed that the photosensitive webs 22a and 22b sent out from the 1st and 2nd web sending mechanisms 32a and 32b are supplied to the attachment mechanism 46 correctly, without extending, but actually Since the flexible photosensitive webs 22a and 22b are extended by a predetermined amount under the influence of tension or heat, the photosensitive resin layer 28 may not be transferred to the predetermined position of the glass substrate 24 with high precision. .

In the CCD cameras 72a and 72b constituting the first and second detection mechanisms 47a and 47b, the substrate tip detection sensor 94 detects the tip of the glass substrate 24 so that the photosensitive webs 22a and 22b are used. And when conveyance of the glass substrate 24 is stopped, the image containing the half cut part 34 and the reference piece 67a, 67b by the peeling part 30aa side is picked up, and the image is a position shift amount calculation part. Supply to 120. The position shift amount calculation unit 120 calculates the position shift amounts ΔLa and ΔLb of the half cut portions 34 with respect to the front end portions of the reference pieces 67a and 67b which are reference positions based on the supplied image.

In this case, if the upstream side to which the photosensitive webs 22a and 22b are supplied to the reference piece 67a, 67b is + and the downstream side is-, for example, the code | symbol of position shift amount (DELTA) La, (DELTA) Lb, When the position shift amounts ΔLa and ΔLb are +, the photosensitive resin layer 28 attached to the glass substrate 24 is extended by the position shift amounts ΔLa and ΔLb than the reference length L, When it is-, it can be determined that it is shorter than the reference length (L).

When the calculated position shift amounts? La and? Lb are within a predetermined allowable amount, the position shift amount calculation unit 120 supplies the position shift amounts? La and? Lb to the control pulse correction unit 123 to provide photosensitivity. The lamination control pulses of the webs 22a and 22b are corrected according to the positional shift amounts? La and? Lb.

Next, the CCD cameras 72a and 72b constituting the first and second detection mechanisms 47a and 47b have the long photosensitive webs 22a and 22b of the protective film 30 under the rotational action of the rubber roller 80a. When conveyed and stopped by the distance corresponding to the remaining portion 30b width M, the image including the half cut portion 34 and the reference pieces 67a and 67b on the peeling portion 30ab side is picked up and imaged. Is supplied to the position shift amount calculator 120. The position shift amount calculation unit 120 calculates the position shift amounts DELTA Ma and DELTA Mb of the half cut portions 34 with respect to the distal end portions of the reference pieces 67a and 67b which are the reference positions based on the supplied image.

In this case, based on the position shift amount (DELTA) Ma, (DELTA) Mb of the half cut part 34 of the peeling part 30ab side, the amount of change of the width | variety M of the residual part 30b of the protective film 30 can be detected. Can be.

When the calculated position shift amounts? Ma and? Mb are within a predetermined allowable amount, the position shift amount calculation unit 120 supplies the position shift amounts? Ma and? Mb to the control pulse correction unit 123 to provide a long position. The inter-substrate sending control pulses of the photosensitive webs 22a and 22b are corrected according to the positional shift amounts ΔMa and ΔMb.

Thereafter, the roller control unit 126 drives the roller drive motor 124 in accordance with the corrected laminate control pulse and the corrected interspace substrate control pulse, and conveys and controls the long photosensitive webs 22a and 22b.

On the other hand, when the position shift amount? La,? Lb or? Ma,? Mb calculated by the position shift amount calculation unit 120 exceeds a predetermined allowable amount, the first and second processing mechanisms 36a and 36b. This corresponds by correcting the machining position of the half cut portion 34 by (). In this case, the half cut position correction unit 128 changes the machining position of the half cut portion 34 based on the positional shift amount ΔLa, ΔLb or ΔMa, ΔMb, thereby causing the photosensitive webs 22a and 22b to be changed. A half cut portion 34 is formed in the groove.

In the manufacturing apparatus 300 comprised in this way, similarly to 1st Embodiment mentioned above, the adhesion board | substrate 24a laminated by the attachment mechanism 46 is conveyed in the arrow C direction. Then, when the attachment substrate 24a reaches a position corresponding to the inter-substrate web cutting mechanism 48, the inter-substrate web cutting mechanism 48 is in the direction of the arrow C at the same conveyance speed as the attachment substrate 24a. While moving to, the two photosensitive webs 22a and 22b are integrally cut between the attachment substrates 24a.

After this cutting, the inter-substrate web cutting mechanism 48 is returned to a predetermined standby position, while in the attached substrate 24a, the base film 26 and the remaining portion 30b are sequentially peeled off (sheet peeling) so that the photosensitive laminate is 106 is manufactured.

In addition, although the half cut part 34 is detected by receiving the illumination light which permeate | transmitted the photosensitive web 22a, 22b by CCD camera 72a, 72b in each embodiment mentioned above, it is comprised as shown in FIG.
