Description

The manufacturing apparatus and manufacturing method of a photosensitive laminated body {APPARATUS FOR AND METHOD OF MANUFACTURING PHOTOSENSITIVE LAMINATED BODY}

The present invention provides an apparatus for producing 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. And to a manufacturing method.

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

The manufacturing apparatus used for the attachment of this kind of photosensitive sheet body usually conveys a substrate, such as a glass substrate or a resin substrate, at predetermined intervals and conveys them between lamination rollers, and also a range of the photosensitive resin layer adhered to the substrate. The system which conveys the photosensitive sheet body which peeled the protective film corresponding to the said lamination rollers is employ | adopted.

For example, in the manufacturing apparatus disclosed by Unexamined-Japanese-Patent No. 3316093, as shown in FIG. 9, the photosensitive sheet | seat 2 is unwound from the roll 1, and it supplies to the half cutter apparatus 3, and the photosensitive sheet The protective film and the photosensitive resin layer laminated | stacked on the support body which comprise the sieve 2 are cut | disconnected at predetermined spaces. Subsequently, after supplying the said photosensitive sheet | seat 2 to the protective film removal part 4, and peeling the protective film corresponding to the attachment range of the board | substrate 5 using an adhesive tape etc., the thermocompression roller 6a, 6b). On the other hand, between the thermocompression rollers 6a and 6b, the heated substrate 5 is carried in and the protective film is peeled off, so that the photosensitive sheet body 2 is heat-compressed to the lower surface portion of the substrate 5 through the photosensitive resin layer exposed. do. The board | substrate 5 to which the photosensitive sheet | seat 2 was heat-squeezed is carried out from the thermocompression roller 6a, 6b, and is supplied to the separator 7, and the photosensitive sheet | seat 2 between the board | substrates 5 is cut | disconnected. As a result, a photosensitive laminate is produced.

By the way, the photosensitive sheet body 2 is formed by laminating | stacking the photosensitive resin layer and the protective film on a flexible support body, and since it is conveyed in the state which provided the tension, extension is produced in the photosensitive sheet body 2. In particular, since the thermocompression rollers 6a and 6b heat the photosensitive sheet body 2 and adhere to the substrate 5, the extension in the vicinity of the thermocompression rollers 6a and 6b is large. Therefore, it is necessary to adjust the position of the board | substrate 5 with respect to the photosensitive sheet body 2, and to correctly position and attach the photosensitive resin layer with which the protective film peeled in the predetermined range of the board | substrate 5.

In addition, the manufactured photosensitive laminated body needs to test whether the photosensitive sheet | seat body 2 is affixed in the predetermined position of the board | substrate 5. As shown in FIG. In this case, for example, as shown in FIG. 10, while measuring the distances L1f and L1b of the front and rear side ends of the substrate 5 and the side ends of the photosensitive sheet body 2, the substrate 5 is measured. The distances L2f and L2b of the front and rear ends and half-cut portions Hf and Hb formed on the photosensitive sheet body 2, and the distances L1f, L1b and L2f and L2b are within the allowable range. Quality assurance of the photosensitive laminated body is performed by determining whether or not.

However, in the conventional inspection method, since a person measures the attachment position of the photosensitive sheet body 2 to the board | substrate 5, not only does it require a tremendous time for measurement but it may cause a measurement miss, and all the photosensitive laminated bodies manufactured It was very difficult to check efficiently and reliably.

An object of this invention is to provide the manufacturing apparatus and manufacturing method of the photosensitive laminated body which can perform quality assurance of the photosensitive laminated body manufactured by measuring the position of the photosensitive material layer adhering to a board | substrate efficiently and accurately.

First, the elongate photosensitive web 22 is sent out from the photosensitive web roll 23 attached to the web delivery mechanism 32. The elongate photosensitive web 22 is conveyed to the processing mechanism 36.

In the processing mechanism 36, the round blades 52a and 52b move in the width direction of the elongate photosensitive web 22 to move the elongate photosensitive web 22 from the protective film 30 to the photosensitive resin layer 28 to the flexible. The cut to the base film 26 is formed to form half cut portions 34a and 34b spaced apart by the width M of the remaining portion B of the protective film 30 (see FIG. 2). Thereby, in the elongate photosensitive web 22, the peeling part A of the front and the peeling part A of the back are formed with the remaining part B interposed (refer FIG. 2).

In addition, the width M of the remaining portion B is a premise that the elongate photosensitive web 22 does not extend, and the glass substrate 24 supplied between the rubber rollers 80a and 80b of the attachment mechanism 46. It is set based on the distance between them. Further, one set of half cut portions 34a and 34b formed in the width M is formed in the elongated photosensitive web 22 at intervals of the reference length of the photosensitive resin layer 28 attached to the glass substrate 24. do.

Subsequently, the elongate photosensitive web 22 is conveyed to the label adhesive mechanism 40 so that the predetermined attachment part of the protective film 30 is arrange | positioned on the receiving stand 56. In the label adhesive mechanism 40, a predetermined number of adhesive labels 38 are adsorbed and held by the adsorption pads 54b to 54g, so that each adhesive label 38 is placed forward over the remaining portion B of the protective film 30. It adheres integrally to the peeling part A and the peeling part A of the back (refer FIG. 3).

For example, the elongate photosensitive web 22 to which the seven adhesive labels 38 are adhered is peeled off after preventing the tension fluctuation of the sending side via the reservoir mechanism 42, as shown in FIG. It is conveyed to 44 continuously. In the peeling mechanism 44, the flexible base film 26 of the elongate photosensitive web 22 is adsorbed and held on the suction drum 62, and the protective film 30 leaves the remaining portion B, and the elongated photosensitive It peels off the web 22. This protective film 30 is peeled off through the peeling roller 63 and wound up by the protective film winding part 64 (refer FIG. 1).

Under the action of the peeling mechanism 44, after the protective film 30 is peeled off from the flexible base film 26 leaving the remaining portion B, the elongated photosensitive web 22 is tensioned by the tension control mechanism 66. Adjustment is performed, and then the image | photograph of the elongate photosensitive web 22 containing the half cut parts 34a and 34b is image | photographed in the imaging | photography part 47 at predetermined | prescribed imaging timing.

The elongate photosensitive web 22 which passed the imaging part 47 is conveyed to the attachment mechanism 46, and the transfer process (lamination) of the photosensitive resin layer 28 with respect to the glass substrate 24 is performed. In this case, the positions of the half cut portions 34a and 34b in the attachment mechanism 46 are adjusted based on the images of the half cut portions 34a and 34b picked up by the imaging unit 47.

In the attachment mechanism 46, initially, the rubber rollers 80a and 80b are set in the spaced apart state, and the half cut part 34a of the long shape photosensitive web 22 is located in the predetermined position between the rubber rollers 80a and 80b. The conveyance of the elongate photosensitive web 22 is stopped once in the state where is located. In this state, the tip end portion of the glass substrate 24 heated to a predetermined temperature by the substrate heating unit 74 constituting the substrate supply mechanism 45 is provided between the rubber rollers 80a and 80b by the transfer unit 76. When brought in, the backup roller 82b and the rubber roller 80b are raised under the action of the pressurizing cylinder 84, and the glass substrate 24 and the elongate photosensitive web 22 are predetermined between the rubber rollers 80a and 80b. Is pressed into the press pressure. In addition, the rubber rollers 80a and 80b are heated by predetermined | prescribed lamination temperature.

Next, the rubber rollers 80a and 80b rotate, and the glass substrate 24 and the elongate photosensitive web 22 are conveyed in the arrow Y direction. As a result, the photosensitive resin layer 28 is melted by heating and transferred (laminated) to the glass substrate 24.

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 degree-90 degree The press pressures (linear pressure) of the rubber rollers 80a and 80b are 50 N / cm to 400 N / cm.

When the lamination of one sheet of the elongate photosensitive web 22 with respect to the glass substrate 24 is completed, the rotation of the rubber rollers 80a and 80b is stopped, while the elongated photosensitive web 22 is laminated to the glass substrate 24. ) Is clamped by the substrate transfer roller 90a. At this time, the half cut part 34b is arrange | positioned in the predetermined position between the rubber rollers 80a and 80b.

Then, the rubber roller 80b is retracted in the direction away from the rubber roller 80a, the clamp is released, and the rotation of the substrate transfer roller 90a is started again at a low speed so that the elongated photosensitive web 22 is formed on the glass substrate. The photosensitive laminated body laminated to (24) is conveyed by the distance corresponding to the width | variety M of the remaining part B of the protective film 30 in the arrow Y direction, and the next half cut part 34a is a rubber roller. After being conveyed to the predetermined position below 80a, rotation of the rubber rollers 80a and 80b is stopped. In addition, the process which conveys the elongate photosensitive web 22 only between half cut parts 34a and 34b is called "inter-board feed" below.

On the other hand, the next glass substrate 24 is conveyed toward the attachment position through the substrate supply mechanism 45 in the said state. By repeating the above operations, the photosensitive laminate is continuously produced.

In that case, the photosensitive laminated body is covered by the remaining part B of the protective film 30 which each edge part shows 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 polluted by the said photosensitive resin layer 28. FIG.

When the glass substrate 24 to which the photosensitive resin layer 28 is attached by the attachment mechanism 46 is once in a stopped state after the elongate photosensitive web 22 is transferred between boards by the attachment mechanism 46, The elongate photosensitive web 22 between the glass substrates 24 is cut | disconnected by the cutter mechanism 48 arrange | positioned between board | substrate conveyance rollers 90b and 90c, and it becomes the photosensitive laminated body 24a. In addition, the protective film 30 remains in this photosensitive laminated body 24a.

The separated photosensitive laminate 24a is once laminated to the stocker 94 by the robot 96. Subsequently, after the photosensitive laminated body 24a laminated | stacked on the stocker 94 is transferred to the peeling part 98, the protective film 30 is peeled from the photosensitive laminated body 24a through the peeling roller 100, and a glass substrate is carried out. The photosensitive laminated body 24b with only the photosensitive resin layer 28 attached to 24 is manufactured. In addition, the protective film 30 peeled from the photosensitive laminated body 24a is wound up by the winding roller 102. FIG.

Here, since the elongate photosensitive web 22 is supplied in the state in which the predetermined tension was given, since the elongate photosensitive web 22 is heated in the attachment mechanism 46 and affixed to the glass substrate 24, extension | stretching will generate | occur | produce. In this case, the attachment position of the photosensitive resin layer 28 to the glass substrate 24 may become inappropriate depending on the extension amount of the elongate photosensitive web 22.

Therefore, the detection part 104 arrange | positioned downstream of the peeling part 98 detects the attachment position of the photosensitive resin layer 28 in the photosensitive laminated body 24b.

First, as shown in FIG. 4, the front end part of the glass substrate 24 with which the photo sensor 106 which comprises the detection part 104 is conveyed, or the front end part of the photosensitive resin layer 28 attached to the glass substrate 24 is detected. The lower surface end detection signal is output to the CCD cameras 108a and 108b. The CCD cameras 108a and 108b capture images of the imaging regions 109a and 109b of the glass substrate 24 in accordance with the end detection signal. In this case, the imaging area | region 109a, 109b contains the image of the front-end corner part of the glass substrate 24, and the front-end corner part of the photosensitive resin layer 28. As shown in FIG.

The image processing unit 120 processes the image photographed by the CCD cameras 108a and 108b, and specifies the front end corner portion of the glass substrate 24 and the front end corner portion of the photosensitive resin layer 28. The adhesion position calculation part 122 is the distance L1f of the side part of the glass substrate 24 and the side part of the photosensitive resin layer 28 in the front-end part based on the information of the position of each corner part identified, and the glass substrate ( The distance L2f of the front end of the front part 24 and the front end of the photosensitive resin layer 28 is calculated (see FIG. 5).
