The present invention provides a photosensitive laminate which sends a substrate and an elongated photosensitive web having a photosensitive material layer formed on a support between a pair of pressing rollers, and attaches the photosensitive material layer to the substrate to produce a photosensitive laminate. It relates to a manufacturing apparatus and a manufacturing method.

For example, in a liquid crystal panel substrate, a printed wiring board, and a PDP panel substrate, a photosensitive sheet member (photosensitive web) having a photosensitive resin layer (photosensitive material layer) is attached to the substrate surface. As for the photosensitive sheet body, the photosensitive resin layer and the protective film are laminated | stacked in order on the flexible plastic support body.

The manufacturing apparatus used for the attachment of this kind of photosensitive sheet body usually conveys substrates such as glass substrates and resin substrates at predetermined intervals, and at the same time, corresponding to the range of the photosensitive resin layer attached to the substrates. The method of peeling a protective film from a sheet | seat body is employ | adopted.

For example, in the manufacturing apparatus disclosed in Japanese Unexamined Patent Application Publication No. 11-34280, the laminated film (photosensitive sheet member) 1a released from the film roll 1, as shown in Fig. 9, is a 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 conveyance amount of the laminated body film 1a is attached to this guide roller 2b.

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 of the cover film (not shown) of the laminate film 1a are moved. 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, 8b, and then, by the winding roll 9, Wind up. Thereby, the peeling part of a cover film peels from the photosensitive resin layer and is wound up to the winding roll 9 with the adhesive tape 7a.

This is done.

In this case, assuming that the photosensitive webs 22a and 22b do not extend, the laser displacement meter and the CCD cameras 72a and 72b move the half cut portion 34 (FIG. 2) on the rear side of the peeling portion 30ab. When it detects, it attaches with the 1st and 2nd detector opening 47a, 47b so that the half cut part 34 of the front peeling part 30aa side which precedes a predetermined position between the rubber rollers 80a, 80b may be arrange | positioned. It is assumed that the length of the conveyance path between the mechanisms 46 is set.

Thus, after the laser displacement meters and the CCD cameras 72a and 72b detect the half cut portion 34 on the side of the peeling portion 30ab on the rear side, the photosensitive webs 22a and 22b are formed on the remaining portions of the protective film 30 ( While conveying and stopping by the distance L corresponding to the width | variety of 30b), the glass substrate 24 is conveyed to an attachment position in the state heated beforehand under the action of the board | substrate conveyance mechanism 45. FIG. The glass substrate 24 is disposed once between the rubber rollers 80a and 80b corresponding to the attachment portion of the photosensitive resin layer 28 of the photosensitive webs 22a and 22b in parallel.

Then, by raising the backup roller 82b and the rubber roller 80b, the glass substrate 24 is sandwiched between the rubber rollers 80a and 80b at a predetermined press pressure. The roller controller 123 (FIG. 5) drives the roller drive motor 120 based on the roller feed pulses, and arrows the photosensitive webs 22a, 22b and the glass substrate 24 under the rotational action of the rubber roller 80a. It conveys in the direction (C). As a result, each parallel photosensitive resin layer 28 is transferred (laminated) to the glass substrate 24. In this case, assuming that the photosensitive webs 22a and 22b have no elongation, the photosensitive resin layer 28 of the photosensitive webs 22a and 22b is separated from the half cut portion 34 on the side of the peeling portion 30ab on the rear side. It is accurately transferred to a predetermined portion of (24).

Moreover, 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-140 degreeC, and the rubber hardness of the said rubber rollers 80a, 80b is 40 degreeC-90 degreeC 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 moved by the substrate transfer roller 92. Clamped. At this time, as will be described later, positions of the rear end of the preceding glass substrate 24 and the rear end of the photosensitive resin layer 28 are detected using the CCD cameras 96a to 96c.

Then, the rubber roller 80b is evacuated in the direction away from the rubber roller 80a, the clamp is released, the rotation of the substrate transfer roller 92 is started, and the attachment substrate 24a is moved in the direction of the arrow C. It is conveyed by the distance L corresponding to the width | variety of the remaining part 30b of the protective film 30, and the half cut part 34 of the back of the protective film 30 is a predetermined position near the lower part of the rubber roller 80a. Go to. At this time, as will be described later, the positions of the front end of the laminated glass substrate 24 and the front end of the photosensitive resin layer 28 are detected using the CCD cameras 96a to 96c.

On the other hand, the next glass substrate 24 is conveyed toward the attachment position via the substrate conveyance mechanism 45. By repeating the above operation, the attachment substrate 24a is continuously manufactured.

At that time, as shown in FIG. 4, the end portions of the attachment substrate 24a are covered by the remaining portions 30b. Therefore, when the photosensitive resin layer 28 is transferred to the glass substrate 24, the rubber rollers 80a and 80b are not polluted by the photosensitive resin layer 28. As shown in 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 enters and rises between the glass substrates 24, and by this, the protective film 30 between the glass substrates 24 is lifted, and the adjacent glass substrates 24 are lifted. Peeled from the rear end and the front end).

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. Further, after the separation at the trouble stop or the separation at the defective part, the front end of the base film 26 of the mounting 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 via the auto attacher 150.

The attachment substrate 24a on which the base film 26 has been peeled off is disposed at an inspection station corresponding to the measuring device 158. In this inspection station, the glass substrate 24 inputs the image of the glass substrate 24 and the photosensitive resin layer 28 with the four cameras 160 in the fixed position. Then, 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, without extending | stretching, In fact, Since the flexible photosensitive webs 22a and 22b are stretched by a predetermined amount under the influence of tension or heat, there is a concern that the photosensitive resin layer 28 is not accurately transferred to a predetermined position of the glass substrate 24.

5-7, the correction method of the attachment position of the photosensitive resin layer 28 with respect to the glass substrate 24 is demonstrated.

First, when the lamination for one sheet is completed and the substrate front end detection sensor 94 detects the front end of the glass substrate 24 (step S1), the roller control unit 123 controls the roller drive motor 120 to control the rubber roller. The rotation of 80a is stopped. Thereby, conveyance of the photosensitive webs 22a and 22b is stopped (step S2).

Subsequently, the illumination light from the illumination light sources 98a to 98c is irradiated to the rear ends of the glass substrate 24 and the photosensitive resin layer 28, and the illumination light transmitted therethrough is received by the CCD cameras 96a to 96c. Image information indicating the attachment state at the rear end is detected (step S3). The image information detected by the CCD cameras 96a to 96c is supplied to the attachment position calculation unit 124, and the attachment position of the rear end is calculated by performing predetermined image processing (step S4).

In this case, the attachment position calculation unit 124 shows the rear end of the glass substrate 24 and the photosensitive property attached thereto based on the image information acquired by the CCD cameras 96a to 96c, as shown in Fig. 7A. The distances EB1, EB2 and EA1, EA2 between the rear ends of the photosensitive resin layers 28 in the webs 22a and 22b are calculated. The attachment position calculation unit 124 also calculates the distances EB3, EA3, EA4 between the side of the glass substrate 24, the photosensitive webs 22a, 22b, and the photosensitive webs 22a, 22b.

Next, after performing transfer between board | substrates which conveys the photosensitive webs 22a and 22b by the distance L corresponding to the width | variety of the width | variety of the remaining part 30b of the protective film 30, and stopping conveyance (step S5), The CCD cameras 96a to 96c are used to detect image information indicating the adhered state at the distal end of the glass substrate 24 and the photosensitive resin layer 28 (step S6). The attachment position of the tip portion is calculated (step S7).

In this case, as shown in FIG. 7B, the attachment position calculating unit 124 is formed of the tip of the glass substrate 24 and the photosensitive resin layer 28 in the photosensitive webs 22a and 22b attached thereto. The distances FB1, FB2 and FA1, FA2 between the tip portions are calculated. The attachment position calculation unit 124 also calculates the distances FB3, FA3, FA4 between the side of the glass substrate 24, the photosensitive webs 22a, 22b, and the photosensitive webs 22a, 22b.

The adhesion state determination unit 126 determines the attachment state of the photosensitive resin layer 28 to the glass substrate 24 based on each attachment position calculated by the attachment position calculation unit 124 (step S8).

For example, if the calculated distances EB1, EB2, EA1, EA2, FB1, FB2, FA1, FA2 are all within the allowable range, it is determined that there is no position shift (step S9), and the position shift is not corrected. Continue the attachment process.

On the other hand, although any one of the distances (EB1, EB2, EA1, EA2, FB1, FB2, FA1, FA2) exceeds the allowable range, the relative positional relationship between the glass substrate 24 and the photosensitive web 2225a, 22b When it is possible to make it within the allowable range by adjusting, the attachment state determining unit 126 determines the positional shift between the glass substrate 24 and the photosensitive webs 22a and 22b (step S10), and the roller for conveying between the substrates. Correction data for correcting the feed pulse is supplied to the roller feed pulse correction unit 128. The roller feed pulse correction unit 128 corrects the roller feed pulses according to the correction data, and supplies them to the roller control unit 123. The roller control unit 123 corrects the distance corresponding to the width L of the remaining portion 30b of the photosensitive webs 22a and 22b by the amount according to the correction data, and conveys the photosensitive webs 22a and 22b ( Step S11). As a result, the position shift between the both ends of the glass substrate 24 and the both ends of the photosensitive resin layer 28 can be made into the tolerance range.

In addition, any one of the distances (EB1, EB2, EA1, EA2, FB1, FB2, FA1, FA2) exceeds the allowable range, and adjusts the relative positional relationship between the glass substrate 24 and the photosensitive webs 22a and 22b. Even if the misalignment cannot be corrected within the allowable range, it is assumed that the photosensitive webs 22a and 22b are stretched more than the allowable or the difference in characteristics between the photosensitive webs 22a and 22b is large. In this case, the attachment state determination unit 126 supplies correction data for correcting the position of the half cut portion 34 to the half cut position correction unit 130. The half cut position correction unit 130 supplies the machining position data corrected according to the correction data to the machining tool control unit 133, and the machining tool control unit 133 has a half cut portion 34 at a position corresponding to the corrected machining position data. ) Is formed (step S12).

In addition, when the distance EB3 between the side part of the attachment board | substrate 24a and the side parts of the photosensitive webs 22a and 22b, and the distance EA3 between the photosensitive webs 22a and 22b exceed the permissible range, it is an example. For example, it is possible to adjust the conveyance system or photosensitive web 22a, 22b which supplies each photosensitive web 22a, 22b by moving to the direction orthogonal to a conveyance direction according to the correction data of these distances.

As described above, the adhesion substrate 24a of high quality can be produced by adjusting the attachment position of the photosensitive resin layer 28 to the glass substrate 24.
