Description

  The present invention provides a photosensitive laminate by feeding a substrate and a long photosensitive web provided with a photosensitive material layer on a support between a pair of pressure rollers, and affixing the photosensitive material layer to the substrate. The present invention relates to a manufacturing apparatus and a manufacturing method for a photosensitive laminate.

  For example, a liquid crystal panel substrate, a printed wiring substrate, and a PDP panel substrate are configured by attaching a photosensitive sheet (photosensitive web) having a photosensitive resin layer (photosensitive material layer) to the substrate surface. In the photosensitive sheet body, for example, a photosensitive resin layer and a protective film are sequentially laminated on a flexible plastic support.

  A manufacturing apparatus used for adhering this type of photosensitive sheet body is usually attached to the substrate while a substrate such as a glass substrate or a resin substrate is transported between the lamination rollers at a predetermined interval. A method is adopted in which a photosensitive sheet body from which a protective film corresponding to the range of the photosensitive resin layer is peeled is conveyed between the lamination rollers.

  For example, in the manufacturing apparatus disclosed in Patent Document 1, as shown in FIG. 9, the photosensitive sheet body 2 is unwound from the roll 1 and supplied to the half cutter apparatus 3, thereby supporting the photosensitive sheet body 2. The protective film and the photosensitive resin layer laminated on the top are cut at a predetermined interval. Next, the photosensitive sheet body 2 is supplied to the protective film removing unit 4, and the protective film corresponding to the attachment range of the substrate 5 is peeled off using an adhesive tape or the like, and then supplied between the thermocompression rollers 6a and 6b. . On the other hand, the heated substrate 5 is carried between the thermocompression rollers 6a and 6b, and the photosensitive sheet 2 is placed on the lower surface portion of the substrate 5 through the photosensitive resin layer exposed by peeling off the protective film. It is thermocompression bonded. The substrate 5 on which the photosensitive sheet body 2 has been heat-pressed is unloaded from the thermo-compression rollers 6a and 6b, and then supplied to the separating device 7, where the photosensitive sheet body 2 between the substrates 5 is cut to make it photosensitive. A laminate is produced.

  By the way, the photosensitive sheet 2 is formed by laminating a photosensitive resin layer and a protective film on a flexible support, and is transported in a tensioned state. 2 extends. In particular, the thermocompression rollers 6a and 6b heat the photosensitive sheet body 2 and affix it to the substrate 5, so that the extension in the vicinity of the thermocompression rollers 6a and 6b is large. Therefore, it is necessary to adjust the position of the substrate 5 with respect to the photosensitive sheet body 2 and accurately position and affix the photosensitive resin layer from which the protective film has been peeled to a predetermined range of the substrate 5.

  In addition, it is necessary to inspect whether or not the photosensitive sheet 2 is attached to a predetermined position of the substrate 5 in the manufactured photosensitive laminate. In this case, for example, as shown in FIG. 10, the distances L1f and L1b between the front and rear side edges of the substrate 5 and the side edges of the photosensitive sheet body 2 are measured, and the front and rear edges of the substrate 5 are measured. And the distances L2f and L2b between the half-cut portions Hf and Hb formed on the photosensitive sheet body 2 and determining whether these distances L1f and L1b and L2f and L2b are within an allowable range. The quality of photosensitive laminates is guaranteed.

  However, in the conventional inspection method, since the attachment position of the photosensitive sheet body 2 to the substrate 5 is manually measured, not only does it take a long time to measure, but there is a risk of causing a measurement error, which is manufactured. It was extremely difficult to inspect all the photosensitive laminates efficiently and reliably.

However, on the contrary, the web feeding mechanism 32 to the photographing unit 47 are arranged below the pasting mechanism 46, and the long photosensitive web 22 is turned upside down. Thus, the photosensitive resin layer 28 may be attached to the lower side of the glass substrate 24, or the conveying path of the long photosensitive web 22 may be configured linearly.

  The inside of the manufacturing apparatus 20 is partitioned into a first clean room 112a and a second clean room 112b through a partition wall 110.

  Next, operation | movement of the manufacturing apparatus 20 comprised as mentioned above is demonstrated in relation to the manufacturing method which concerns on this invention.

  First, the long photosensitive web 22 is fed from the photosensitive web roll 23 attached to the web feed mechanism 32. The long 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 long photosensitive web 22, and the long photosensitive web 22 is moved from the protective film 30 to the photosensitive resin layer 28 to the flexible base film. Cut to 26 to form half-cut portions 34a and 34b separated by the width M of the remaining portion B of the protective film 30 (see FIG. 2). As a result, the long photosensitive web 22 is provided with a front peeling portion A and a rear peeling portion A across the remaining portion B (see FIG. 2).

  The width M of the remaining portion B is set on the basis of the distance between the glass substrates 24 supplied between the rubber rollers 80a and 80b of the attaching mechanism 46 on the assumption that the long photosensitive web 22 does not extend. The A pair of half-cut portions 34 a and 34 b formed with a width M are formed on the long photosensitive web 22 at intervals of a reference length of the photosensitive resin layer 28 attached to the glass substrate 24.

  Next, the long photosensitive web 22 is conveyed to the label adhering mechanism 40, and a predetermined application portion of the protective film 30 is arranged on the cradle 56. In the label adhering mechanism 40, a predetermined number of adhesive labels 38 are adsorbed and held by the adsorbing pads 54b to 54g, and each adhering label 38 straddles the remaining portion B of the protective film 30, and the front peeling portion A and the rear peeling portion A. Are integrally bonded to each other (see FIG. 3).

  For example, as shown in FIG. 1, the long photosensitive web 22 to which seven adhesive labels 38 are bonded is continuously connected to the peeling mechanism 44 after the tension on the delivery side is prevented via the reservoir mechanism 42. To be transported. In the peeling mechanism 44, the flexible base film 26 of the long photosensitive web 22 is sucked and held by the suction drum 62, and the protective film 30 is peeled off from the long photosensitive web 22 leaving the remaining portion B. Is done. The protective film 30 is peeled off via the peeling roller 63 and wound around the protective film take-up portion 64 (see 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 tension of the long photosensitive web 22 is adjusted by the tension control mechanism 66, Next, in the photographing unit 47, an image of the long photosensitive web 22 including the half cut portions 34a and 34b is photographed at a predetermined photographing timing.

  The long photosensitive web 22 that has passed through the photographing section 47 is conveyed to the attaching mechanism 46, whereby the photosensitive resin layer 28 is transferred (laminated) to the glass substrate 24. In this case, the positions of the half cut portions 34a and 34b in the attaching mechanism 46 are adjusted based on the images of the half cut portions 34a and 34b photographed by the photographing unit 47.

  In the pasting mechanism 46, the rubber rollers 80a and 80b are initially set in a separated state, and the half-cut portion 34a of the long photosensitive web 22 is positioned at a predetermined position between the rubber rollers 80a and 80b. The conveyance of the long photosensitive web 22 is temporarily stopped. In this state, when the tip of the glass substrate 24 heated to a predetermined temperature by the substrate heating unit 74 constituting the substrate supply mechanism 45 is carried between the rubber rollers 80a and 80b by the transport unit 76, the action of the pressure cylinder 84 is achieved. The backup roller 82b and the rubber roller 80b are raised below, and the glass substrate 24 and the long photosensitive web 22 are sandwiched between the rubber rollers 80a and 80b with a predetermined pressing pressure. The rubber rollers 80a and 80b are heated to a predetermined laminating temperature.

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

  The laminating conditions include a speed of 1.0 m / min to 10.0 m / min, a temperature of the rubber rollers 80a and 80b of 80 ° C to 140 ° C, a rubber hardness of the rubber rollers 80a and 80b of 40 ° to 90 °, The pressing pressure (linear pressure) of the rubber rollers 80a and 80b is 50 N / cm to 400 N / cm.

  When the lamination of one sheet of the long photosensitive web 22 is completed on the glass substrate 24, the rotation of the rubber rollers 80a and 80b is stopped, while the glass substrate 24 on which the long photosensitive web 22 is laminated is stopped. The leading end is clamped by the substrate transport roller 90a. At this time, a half-cut portion 34b is disposed at a predetermined position between the rubber rollers 80a and 80b.

  Then, the rubber roller 80b is retracted in a direction away from the rubber roller 80a to release the clamp, and the rotation of the substrate transport roller 90a is started again at a low speed, and the long photosensitive web 22 is laminated on the glass substrate 24. After the photosensitive laminate is transported in the direction of arrow Y by a distance corresponding to the width M of the remaining portion B of the protective film 30, the next half-cut portion 34a is transported to a predetermined position near the lower portion of the rubber roller 80a, and then the rubber roller The rotation of 80a and 80b is stopped. In addition, the process which conveys the elongate photosensitive web 22 only between the half cut site | parts 34a and 34b is called "inter-substrate feeding" below.

  On the other hand, in the above state, the next glass substrate 24 is conveyed toward the attaching position via the substrate supply mechanism 45. By repeating the above operation, the photosensitive laminate is continuously manufactured.

  In that case, each edge part of the photosensitive laminated body is covered with the remaining part B of the protective film 30 shown in FIG. Therefore, when the photosensitive resin layer 28 is transferred to the glass substrate 24, the rubber rollers 80a and 80b are not soiled by the photosensitive resin layer 28.

  The glass substrate 24 to which the photosensitive resin layer 28 is attached by the attaching mechanism 46 is temporarily stopped after the long photosensitive web 22 is fed between the substrates by the attaching mechanism 46. The long photosensitive web 22 between the glass substrates 24 is cut by the cutter mechanism 48 disposed between 90b and 90c to form a photosensitive laminate 24a. Note that the protective film 30 remains in the photosensitive laminate 24a.

  The separated photosensitive laminate 24 a is once laminated on the stocker 94 by the robot 96. Next, the photosensitive laminated body 24a laminated on the stocker 94 is transferred to the peeling portion 98, and then the protective film 30 is peeled off from the photosensitive laminated body 24a via the peeling roller 100, whereby the glass substrate 24. A photosensitive laminate 24b having only the photosensitive resin layer 28 attached thereto is manufactured. The protective film 30 peeled from the photosensitive laminate 24 a is taken up by the take-up roller 102.

  Here, the long photosensitive web 22 is supplied in a state where a predetermined tension is applied, and is heated and pasted on the glass substrate 24 by the pasting mechanism 46, so that the elongation occurs. . In this case, the attachment position of the photosensitive resin layer 28 to the glass substrate 24 may be inappropriate depending on the extension amount of the long photosensitive web 22.

  Therefore, the detection unit 104 disposed on the downstream side of the peeling unit 98 detects the attachment position of the photosensitive resin layer 28 in the photosensitive laminate 24b.

  First, as shown in FIG. 4, when the photosensor 106 constituting the detection unit 104 detects the front end portion of the glass substrate 24 to be transported or the front end portion of the photosensitive resin layer 28 attached to the glass substrate 24, The edge detection signal is output to the CCD cameras 108a and 108b. The CCD cameras 108a and 108b take images of the shooting areas 109a and 109b of the glass substrate 24 in accordance with the edge detection signal. In this case, the photographing areas 109 a and 109 b include images of the front end corner portion of the glass substrate 24 and the front end corner portion of the photosensitive resin layer 28.

  The image processing unit 120 processes the images taken by the CCD cameras 108 a and 108 b 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 affixing position calculation unit 122 is based on the information on the position of each specified corner portion, the distance L1f between the side portion of the glass substrate 24 and the side portion of the photosensitive resin layer 28 at the front end portion, and the glass substrate 24 A distance L2f between the front end portion and the front end portion of the photosensitive resin layer 28 is calculated (see FIG. 5). The determination unit 124 compares the calculated distances L1f and L2f with a preset allowable distance, and determines whether the distances L1f and L2f are within the allowable range. The determination result is displayed on the display unit 126, so that the operator can be notified of the state of the photosensitive resin layer 28 attached to the front end side of the photosensitive laminate 24b.

  Similarly, images are taken by the CCD cameras 108a and 108b at the timing when the photo sensor 106 detects the rear end portion of the glass substrate 24 or the rear end portion of the photosensitive resin layer 28 attached to the glass substrate 24. Distances L1b and L2b between the glass substrate 24 and the photosensitive resin layer 28 at the end are calculated, and a determination result based on the calculation result is displayed on the display unit 126 (see FIG. 6).

  As described above, the attachment state of the photosensitive resin layer 28 to the glass substrate 24 is automatically detected, and the determination result is displayed on the display unit 126.
