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. 7, 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.

Japanese Patent No. 3316093

  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.

  In this case, 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 is peeled off to a predetermined range of the substrate 5. However, when such an adjustment process is performed, the position of the substrate 5 supplied to the separation device 7 varies, and the separation device 7 and the substrate 5 may interfere with each other and the substrate 5 may be damaged.

  In order to avoid such a situation, it is conceivable that a substrate detection sensor is arranged in the vicinity of the separation device 7 and the position of the substrate 5 with respect to the separation device 7 is detected.

  However, if the distance between the substrates 5 is set large in order to secure the installation space for the substrate detection sensor, the range of the photosensitive sheet body 2 between the substrates 5 that does not contribute to the production of the photosensitive laminate is increased, which is extremely uneconomical. It is. Therefore, it is necessary to set the distance between the substrates 5 as narrow as possible.

  The present invention measures the position of the substrate on which the long photosensitive web is attached with high accuracy, and can reliably avoid interference between the substrate and a cutting portion that cuts between the substrates. It is an object of the present invention to provide an apparatus and a method for manufacturing a photosensitive laminate that can reduce the amount of a long photosensitive web that is discarded without contributing to the manufacture of the photosensitive laminate.

The present invention feeds a long photosensitive web in which a photosensitive material layer and a protective film are sequentially laminated on a support, and a processing site corresponding to a boundary position between a peeled portion and a remaining portion of the protective film, A pair of pressure bonding is formed in a portion extending from the protective film to the photosensitive material layer, and after peeling off the peeling portion of the protective film, the long photosensitive web is heated together with the substrate supplied at a predetermined interval. It is continuously fed between rollers, the remaining portion of the protective film is disposed between the substrates, and the exposed photosensitive material layer is attached to the substrates, and then the elongated photosensitive web is placed between the substrates. In the photosensitive laminate manufacturing apparatus for manufacturing a photosensitive laminate by cutting and separating

It is characterized by comprising.

  In the present invention, the position of the corner portion of the substrate is measured at a predetermined position on the downstream side of the cutting portion that cuts the long photosensitive web between the substrates, and based on the measurement result, the inter-substrate position is determined at the predetermined position of the cutting portion. It is possible to avoid interference between the substrate and the cutting portion by determining whether or not the long photosensitive web is disposed and controlling the cutting portion based on the determination result.

  Further, since the measurement unit is arranged on the downstream side of the cutting unit and the position of the substrate is measured, it is not necessary to secure the arrangement space of the measurement unit in the cutting unit. Accordingly, the distance between the substrates at the cut portion can be set as small as possible, and thereby the amount of the long photosensitive web that is discarded without contributing to the production of the photosensitive laminate can be reduced. .

And a stop position detection sensor 78 for detecting the stop position of the end portion. The substrate heating unit 74 constantly monitors the temperature of the glass substrate 24. When an abnormality occurs, the conveyance unit 76 is stopped or alarmed, and abnormal information is transmitted to cause the abnormal glass substrate 24 to be discharged NG in the subsequent process. It can be used for management or production management. An air levitation plate (not shown) is disposed in the conveyance unit 76, and the glass substrate 24 is levitated and conveyed in the arrow Y direction. The glass substrate 24 can be transported by a roller conveyor.

  The temperature measurement of the glass substrate 24 is preferably performed in the substrate heating unit 74 or immediately before the attachment position. The measuring method may be a contact type (for example, thermocouple) or a non-contact type.

  The affixing mechanism 46 includes rubber rollers (compression rollers) 80a and 80b that are arranged vertically and heated to a predetermined temperature. Backup rollers 82a and 82b are in sliding contact with the rubber rollers 80a and 80b. One backup roller 82 b is pressed toward the rubber roller 80 b by a pressure cylinder 84 that constitutes a roller clamp portion 83.

  The glass substrate 24 is transported by a plurality of substrate transport rollers 90a to 90d constituting a transport path extending in the arrow Y direction from the pasting mechanism 46. A cutter mechanism 48 is provided between the substrate transport rollers 90b and 90c to cut the long photosensitive web 22 between the glass substrates 24 to separate the photosensitive laminate having the photosensitive material layer attached to the glass substrate 24. (Cutting part) is disposed.

  In addition, a photographing unit 94 for photographing an image of the end of the glass substrate 24 on which the long photosensitive web 22 is attached is disposed at a predetermined position on the downstream side of the substrate transport roller 90d. As shown in FIGS. 4 and 5, the imaging unit 94 receives the illumination light output from the two-dimensional light source 95 and the two-dimensional light source 95 and transmitted through the corner unit 96 that is the end of the glass substrate 24. A CCD camera 97 that captures an image of the corner section 96 and a reference piece 99 that is disposed in a part of the imaging area 98 of the CCD camera 97 and that measures the position of the corner section 96 in the image of the imaging area 98 are provided. Composed.

  Here, the distance L represents the distance between the cutter mechanism 48 and the reference piece 99. The width in the direction orthogonal to the conveying direction of the glass substrate 24 is set wider than the width of the long photosensitive web 22, and the corner portion 96 of the glass substrate 24 overlaps the long photosensitive web 22. It is arranged in the photographing area 98 in such a state that it does not become. Further, unlike the other three corner portions of the glass substrate 24, the corner portion 96 photographed by the CCD camera 97 is formed in a shape that is inclined with respect to the conveyance direction of the glass substrate 24.

  In the manufacturing apparatus 20 configured as described above, the web feed mechanism 32, the processing mechanism 36, the label adhesion mechanism 40, the reservoir mechanism 42, the peeling mechanism 44, the tension control mechanism 66, and the photographing unit 47 are included in the pasting mechanism 46. 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. The first clean room 112a accommodates the web feed mechanism 32 to the tension control mechanism 66, and the second clean room 112b accommodates the mechanism after the photographing unit 47. The first clean room 112a and the second clean room 112b communicate with each other through the penetration part 114.

  FIG. 6 shows a control circuit block diagram of the manufacturing apparatus 20. The control circuit of the manufacturing apparatus 20 includes an image processing unit 126 that processes an image captured by the CCD camera 97 that constitutes the imaging unit 94, and the position of the corner unit 96 with respect to the edge portion of the reference piece 99 based on the processed image information. A displacement amount calculation unit 128 that calculates the displacement amount ΔK, and a cutter control unit 130 that controls the operation of the cutter mechanism 48 based on the displacement amount ΔK of the corner portion 96 calculated by the displacement amount calculation unit 128 are provided. . The cutter control unit 130 determines whether or not the positional deviation amount ΔK of the corner portion 96 is within an allowable range, and displays the determination result on the display unit 132, while the positional deviation amount ΔK is not within the allowable range. In this case, the cutting process of the long photosensitive web 22 by the cutter mechanism 48 is prohibited, or control for changing the cutting position is performed.

  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.

  At that time, as shown in FIG. 4, the ends of the photosensitive laminate are covered with the remaining portion B of the protective film 30. 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 photosensitive laminate manufactured by the attaching mechanism 46 is disposed between the substrate transport rollers 90b and 90c when the long photosensitive web 22 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 and separated by the cutter mechanism 48 provided.

  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, depending on the extension amount of the long photosensitive web 22, there is a possibility that the long photosensitive web 22 between the glass substrates 24 is not disposed at a predetermined cutting position of the cutter mechanism 48.

  Therefore, the cutter control unit 130 controls the cutter mechanism 48 based on the position of the glass substrate 24 measured by the photographing unit 94 disposed at a predetermined position on the downstream side of the cutter mechanism 48, so that the glass substrate 24 and the cutter are connected. Interference with the mechanism 48 is avoided.

  The CCD camera 97 constituting the photographing unit 94 disposed on the downstream side of the cutter mechanism 48 receives the illumination light from the two-dimensional light source 95 through the glass substrate 24, so that the corner portion 96 of the glass substrate 24 Take a picture. In this case, the image of the shooting area 98 includes the image of the reference piece 99 together with the image of the corner portion 96. As shown in FIG. 5, the glass substrate 24 is set wider than the long photosensitive web 22, so that the image of the corner portion 96 can be reliably obtained without being obstructed by the long photosensitive web 22. You can shoot.

  An image photographed by the CCD camera 97 is transmitted as image information to the image processing unit 126, and is subjected to predetermined image processing, whereby position information of the corner unit 96 and the reference piece 99 is acquired. In this case, since the corner portion 96 to be photographed is formed in a shape that is inclined with respect to the conveyance direction of the glass substrate 24, the position information of the corner portion 96 is not confused with the long photosensitive web 22. It can be acquired with certainty. The acquired position information is transmitted to the displacement amount calculation unit 128, and the displacement amount ΔK of the corner portion 96 with respect to the reference piece 99 is calculated.

  The cutter control unit 130 determines whether or not the calculated positional deviation amount ΔK of the corner unit 96 is within an allowable range. In this case, as shown in FIG. 4, since the distance L between the cutter mechanism 48 and the reference piece 99 is fixed, the rear end portion of the glass substrate 24 and the cutter mechanism 48 according to the calculated displacement amount ΔK. It is possible to determine whether the glass substrate 24 and the cutter mechanism 48 interfere with each other.

  The cutter control unit 130 displays the determination result on the display unit 132 and, when it is determined that there is a possibility of interference, controls the cutter mechanism 48 to prohibit cutting processing of the long photosensitive web 22. Do. Thereby, the situation where the glass substrate 24 is damaged can be avoided in advance. In addition, if the cutting mechanism 48 sets a cutting position at which the cutter mechanism 48 does not interfere with the glass substrate 24 based on the positional deviation amount ΔK calculated by the positional deviation amount calculation unit 128, the photosensitivity by the manufacturing apparatus 20 is achieved. The manufacturing process of the laminate can be continued without interruption.
