Description

  The present invention relates to a manufacturing apparatus and a manufacturing method for manufacturing a photosensitive laminate by press-bonding a photosensitive material layer provided on a support to a substrate using a pressure roller.

  For example, using a photosensitive laminate manufacturing apparatus, a photosensitive pigment dispersion (photosensitive material layer) applied to a translucent base film (support) is attached to a glass substrate or a resin substrate, or transferred and melted. The photosensitive laminated body is manufactured by this (refer patent document 1, 2). The photosensitive laminate such as a glass substrate to which the photosensitive material layer has been transferred is exposed and developed by a photolithography method after the support is peeled off, and then the same processing is performed for each photosensitive material layer of a different color. Thus, a color filter substrate for a liquid crystal panel or a PDP panel is manufactured. Note that the photosensitive laminate manufacturing apparatus can also be applied to, for example, manufacturing a printed circuit board in which a wiring circuit is formed on a substrate using a conductive photosensitive material layer.

  FIG. 6 shows a schematic configuration of the photosensitive laminate manufacturing apparatus. In this apparatus, the glass substrate 4 and the photosensitive sheet film 6 are supplied between the pair of pressure rollers 2a and 2b. The photosensitive sheet film 6 is heated by the pressure roller 2a heated to a predetermined temperature, so that the photosensitive material layer applied to the support is melted and applied to the glass substrate 4 by the pressure of the pressure rollers 2a and 2b. Transcribed.

  Here, when the glass substrate 4 and the photosensitive sheet film 6 are pressure-bonded, if a bubble is mixed between them or a wrinkle occurs in the photosensitive sheet film 6, a high-quality color filter substrate is manufactured. Will not be able to. Therefore, an appropriate pressure is applied to the glass substrate 4 and the photosensitive sheet film 6 by the press rollers 2a and 2b, and the photosensitive sheet film 6 is pulled with an appropriate tension that does not sag.

  By the way, in the photosensitive laminate manufacturing apparatus, usually, the photosensitive sheet film 6 is caused to follow the uneven surface of the glass substrate without causing damage to the glass substrate 4 and without generating bubbles or wrinkles, and is crimped. In order to convey them at a constant speed without slipping, rubber layers 3a and 3b are provided on the surfaces of the pressure-bonding rollers 2a and 2b. In this case, when the transfer process of the photosensitive material layer to the glass substrate 4 is repeated, as shown in the conceptual diagram of FIG. 7, streaks 8 which are shading unevenness appear in the photosensitive material layer transferred to the glass substrate 4. There may be a situation where the level of decline is reduced.

  As the reason why the stripe 8 appears, for example, the following is estimated. That is, as shown in FIG. 8, when the pressure rollers 2a and 2b press the glass substrate 4 and the photosensitive sheet film 6, the rubber layers 3a and 3b are deformed, and so-called bulge portions 5a and 5b are generated. In the bulge parts 5a and 5b, although it is local, the substantial radius (referred to as R2) including the rubber layers 3a and 3b of the pressure-bonding rollers 2a and 2b is the substantial radius of the part without the bulge parts 5a and 5b ( R1 is greater than R1 <R2). For this reason, the peripheral speed is increased, and in the bulge portion 5a, the photosensitive sheet film 6 in the portion having the substantial radius R2 may pull the photosensitive material layer 6 having the immediately preceding substantial radius R1.

  In this case, when the surfaces of the rubber layers 3a and 3b of the bulge portions 5a and 5b are new or after the cleaning or polishing process and the coefficient of friction is large, the photosensitivity that contacts the rubber layer 3a before the transfer is performed. The sheet film 6 is conveyed while being stretched, and the photosensitive material layer on the surface thereof is transferred to the glass substrate 4. When the photosensitive sheet film 6 is heated by the pressure roller 2a, the photosensitive sheet film 6 that is in contact with the rubber layer 3a of the pressure roller 2a is softened, so that it is further easily stretched.

  However, if the transfer process is repeated, the surfaces of the rubber layers 3a and 3b deteriorate, or if a part of the composition of the coating film adheres to the rubber layer 3a from the support of the photosensitive sheet film 6 and becomes dirty. The coefficient of friction may decrease. At this time, the photosensitive sheet film 6 in the portion of the substantial radius R1 is pulled by the photosensitive sheet film 6 in the portion of the substantial radius R2, thereby causing a minute intermittent slip between the photosensitive sheet film 6 and the rubber layer 3a. It is considered that a so-called stick-slip phenomenon occurs, and due to this phenomenon, streaks 8 appear in the photosensitive material layer.

  When the friction coefficient of the rubber layer 3a is further reduced, the photosensitive sheet film 6 is always slipped in the portion of the substantial radius R1, and the fluctuation in the conveying speed of the photosensitive sheet film 6 is reduced, resulting in streak 8 No longer appears.

  As a measure for suppressing the appearance of such irregular stripes 8, for example, the rubber layers 3a and 3b attached to the pressure-bonding rollers 2a and 2b are periodically exchanged to change the stable rubber layers 3a and 3b. It is conceivable to maintain the friction coefficient of the rubber layers 3a and 3b with respect to the photosensitive sheet film 6 within a predetermined range by ensuring or periodically cleaning or polishing the surfaces of the rubber layers 3a and 3b. .

  However, since such an operation is very complicated, there is a problem that the operating rate is lowered and the cost is increased. In addition, it is extremely difficult to determine how often the rubber layers 3a and 3b should be maintained, and there is a concern that defective products may be shipped by mistake.

  The present invention has been made in order to solve the above-described problems, and can continue the transfer process in a stable state over a long period of time, thereby ensuring a high operating rate and contributing to cost reduction. It aims at providing the manufacturing apparatus and manufacturing method of a photosensitive laminated body.

  In the photosensitive laminate manufacturing apparatus and method of the present invention, the static friction coefficient of the pressure roller with respect to the support that supports the photosensitive material layer is set in the range of 0.1 to 0.7, and the pressure roller is rotated. By pressing the photosensitive material layer to the substrate via the support, an appropriate slip occurs between the pressure roller and the support, and the support and the substrate are transported in a stable state for a long period of time. It can be transferred to the substrate without unevenness.

  In this case, it is preferable to form a rubber layer on the surface of the pressure roller, and to set the hardness of this rubber layer to 30 to 90 degrees according to JIS K 6253 type A (ISO 7619 type A). If the hardness of the rubber layer is 30 degrees or more, even if the rubber layer is deformed, the photosensitive material layer can be transferred to the substrate in a stable state. On the other hand, if the hardness of the rubber layer exceeds 90 degrees, it is not preferable because the substrate is damaged or the transferability of the photosensitive material layer to the uneven surface of the substrate is deteriorated.

  The pressure roller is heated in the range of 80 to 150 ° C. to melt the photosensitive material layer and transfer it to the substrate. When the temperature of the pressure roller is lower than 80 ° C., the photosensitive material layer is not sufficiently melted, so that there is a possibility that the transfer is not suitably performed. If the temperature of the pressure roller is higher than 150 ° C., the photosensitive material layer may be excessively melted or the support may be thermally deformed.

  The photosensitive material layer is preferably a thermoplastic photosensitive resin layer exhibiting viscosity characteristics in the range of 30 to 30000 Pa · s when heated in the range of 80 to 150 ° C. by the pressure roller. When the viscosity characteristic exceeds the range of 30 to 30000 Pa · s, the photosensitive material layer may not be transferred well to the substrate.

  The pressure applied by the pressure roller is preferably set in the range of 30 to 300 N / cm as the linear pressure with respect to the axial direction of the pressure roller. When this pressure exceeds the range of 30 to 300 N / cm, the photosensitive material layer may not be transferred well to the substrate.

  In the photosensitive laminate production apparatus and production method of the present invention, the photosensitive material layer can be uniformly transferred to the substrate in a stable state over a long period of time. As a result, the frequency of operations such as maintenance of the pressure roller is remarkably reduced, and the operating rate of the apparatus can be improved and the cost can be reduced.

A pressure-bonding mechanism 44 that heat-presses the twelve photosensitive resin layers 18 to the glass substrate 14 is sequentially disposed.

  The reservoir mechanism 36 includes a roller 46 that can swing up and down in order to absorb a speed difference between the tact conveyance of the upstream photosensitive sheet film 12 and the continuous conveyance of the downstream photosensitive sheet film 12. The peeling mechanism 38 has a suction drum 48 that reduces the tension fluctuation of the photosensitive sheet film 12, and a peeling roller 50 is disposed in the vicinity of the suction drum 48. The protective film 20 a is continuously peeled from the photosensitive sheet film 12 via the peeling roller 50 and is wound on the winding portion 52. The tension control mechanism 40 includes a cylinder 54, and the tension of the photosensitive sheet film 12 can be adjusted by the tension dancer 56 swinging and displacing under the driving action of the cylinder 54.

  The detection mechanism 42 is disposed between the tension control mechanism 40 and the pressure-bonding mechanism 44, and is opposed to the film bending roller 58 that curves the photosensitive sheet film 12 toward the protective film 20, and the film bending roller 58. And a detection unit 60 that detects the half cut portions 27a and 27b formed in the sheet film 12.

  A crimping mechanism 44 disposed on the downstream side of the detection mechanism 42 is for thermocompression bonding of the photosensitive resin layer 18 of the photosensitive sheet film 12 to the upper surface portion of the glass substrate 14 supplied from the substrate transport mechanism 62. The pressure rollers 64a and 64b are provided. The substrate transport mechanism 62 that supplies the glass substrate 14 includes a substrate heating unit 66 that is disposed so as to sandwich the glass substrate 14, and a transport unit 68 that transports the glass substrate 14.

  The pressure-bonding rollers 64a and 64b constituting the pressure-bonding mechanism 44 are heating rollers that pressure-bond the photosensitive sheet film 12 and the glass substrate 14 with a linear pressure in the range of 30 to 300 N / cm and heat in the range of 80 to 150 ° C. The rubber layers 65a and 65b are formed on the outer periphery. Backup rollers 70a and 70b are in sliding contact with the pressure rollers 64a and 64b. The backup roller 70 b disposed in the lower part is pressed toward the upper backup roller 70 a by the pressure cylinder 72.

  The pressure rollers 64a and 64b are configured such that the upper pressure roller 64a is a driving side and the lower pressure roller 64b is a driven side. The drive side is preferably the side in contact with the photosensitive sheet film 12, but both the pressure rollers 64a and 64b may be driven to rotate. The pressing rollers 64a and 64b convey the photosensitive sheet film 12 and the glass substrate 14 at a speed of 1.0 to 10 m / min in a state where the photosensitive sheet film 12 and the glass substrate 14 are pressed.

  The rubber layers 65a and 65b are heat resistant rubbers having a hardness of 30 to 90 degrees according to JIS K 6253 type A (ISO 7619 type A), such as silicone rubber, CR (chloroprene rubber), IIR (butyl rubber), EPDM (ethylene).

Friction treatment is applied.

  In this case, examples of the friction reduction treatment of the rubber layers 65a and 65b include surface coating treatment, impregnation treatment, tube hanging, surface polishing treatment, and the like.

  The surface coating treatment includes, for example, PTFE (polytetrafluoroethylene: US DuPont registered trademark), PFA (tetrafluoroethylene perfluoroalkyl vinyl ether copolymer), FEP (fluoroethylene propylene tetrafluoroethylene-hexafluoropropylene co-polymer).

It is a process of applying to the surface and baking.

  The impregnation treatment is a treatment in which the rubber layers 65a and 65b are swollen and impregnated with a low friction material such as that used in the surface coating treatment between molecules.

  Tubing is a process in which a tube made of PTFE or other resin having slipperiness is directly coated on the rubber layers 65a and 65b of the pressure rollers 64a and 64b, and the tube is thermally contracted or an adhesive is used. By doing so, it can be fixed to the pressure rollers 64a and 64b.

  These processes may be performed at least on the pressure roller 64a in contact with the photosensitive sheet film 12, and need not be performed on both the pressure rollers 64a and 64b.

  On the downstream side of the pressure bonding mechanism 44, there are a leading end cutting mechanism 74 that cuts the leading end portion of the photosensitive sheet film 12 at the start of operation and an inter-substrate cutting mechanism 76 that cuts the photosensitive sheet film 12 between the glass substrates 14. Arranged. Further, a film transport roller 78 for pulling out the photosensitive sheet film 12 at the start of operation is disposed between the pressure-bonding rollers 64a and 64b and the leading end cutting mechanism 74, and on the downstream side of the leading end cutting mechanism 74, A substrate transport roller 80 is disposed to transport the glass substrate 14 to which the photosensitive sheet film 12 has been pressure bonded.

  The photosensitive laminate manufacturing apparatus 10 of the present embodiment is basically configured as described above. Next, the operation and effects thereof will be described.

  The photosensitive sheet film 12 supplied from the film roll 22 is conveyed to the processing mechanism 26, and the protective film 20 and the photosensitive resin layer 18 are cut at predetermined lengths by the round blade 24, leaving the base film 16. That is, the photosensitive sheet film 12 has a length L of the photosensitive resin layer 18 to be pressed against the glass substrate 14 and a protective film 20b remaining between the glass substrates 14 by the processing mechanism 26 as shown in FIG. The slit-shaped half-cut portions 27a and 27b are formed at intervals corresponding to the width M of the first reference (see FIG. 2).

  Next, in the label adhering mechanism 34, the label adsorbed to the adsorbing pad 32 is adhered to the protective film 20 of the photosensitive sheet film 12 in which the half cut portions 27a and 27b are formed. In this case, the label is adhered to the protective film 20a that is peeled off from the photosensitive sheet film 12 at both ends thereof in a non-bonded state with respect to the protective film 20b.

  The photosensitive sheet film 12 to which the label is adhered is supplied to the peeling mechanism 38 via a roller 46 constituting the reservoir mechanism 36. In the peeling mechanism 38, the base film 16 of the photosensitive sheet film 12 is adsorbed by the suction drum 48, while the protective film 20 a connected by the label is wound up by the winding unit 52 via the peeling roller 50. As a result, the protective film 20a is continuously peeled from the photosensitive sheet film 12 while the protective film 20b having a width M corresponding to the gap between the glass substrates 14 remains.

  The photosensitive sheet film 12 from which the protective film 20a has been peeled off and the photosensitive resin layer 18 has been partially exposed passes through a tension dancer 56 constituting the tension control mechanism 40 and a film bending roller 58 constituting the detection mechanism 42. And is supplied between the pressure-bonding rollers 64a and 64b in the separated state. When the photosensitive sheet film 12 is cued (at the start of operation), the leading end portion of the photosensitive sheet film 12 is nipped and conveyed by a film conveying roller 78 disposed on the downstream side of the pressure rollers 64a and 64b. To do.

  On the other hand, the glass substrate 14 is heated to a predetermined temperature in the substrate heating unit 66 constituting the substrate transport mechanism 62 and is supplied between the pressure-bonding rollers 64 a and 64 b in a separated state.

  The half-cut portion 27b of the photosensitive sheet film 12 detected by the detection mechanism 42 enters a predetermined position between the pressure rollers 64a and 64b, and the front end portion of the glass substrate 14 is a predetermined distance between the pressure rollers 64a and 64b. When entering the position, the pressure roller 72 presses the backup roller 70b, and the pressure roller 64b cooperates with the upper pressure roller 64a to sandwich the photosensitive sheet film 12 and the glass substrate 14. Next, from the above state, the photosensitive sheet film 12 and the glass substrate 14 are conveyed while being pressurized and heated by the pressure rollers 64a and 64b, so that the photosensitive resin layer 18 at the part where the protective film 20a is peeled off is made of glass. Crimped to a predetermined position of the substrate 14.

  When the leading end of the first glass substrate 14 to which the photosensitive resin layer 18 has been transferred by the pressure rollers 64 a and 64 b approaches the film transport roller 78, the film transport roller 78 moves away from the photosensitive sheet film 12, and from the glass substrate 14. The front end portion of the photosensitive sheet film 12 protruding forward is cut by the front end cutting mechanism 74. Next, the glass substrate 14 to which the photosensitive resin layer 18 has been transferred is nipped and conveyed by a substrate conveying roller 80 disposed downstream of the tip cutting mechanism 74.

  The photosensitive sheet film 12 between the glass substrate 14 to which the photosensitive resin layer 18 is transferred and continuously conveyed as described above and the subsequent glass substrate 14 is disposed downstream of the substrate conveying roller 80. They are separated by being cut by the provided inter-substrate cutting mechanism 76.

  The photosensitive laminate, which is the glass substrate 14 to which the photosensitive resin layer 18 is transferred, is exposed and developed in a predetermined pattern by a photolithography method after the base film 16 is peeled off, and then a photosensitive resin of a different color. A desired color filter substrate is manufactured by repeating the process of transferring the layer 18 to the photosensitive laminate in the same manner.

  Here, the present applicant sets the coefficient of static friction with respect to the base film 16 of the rubber layer 65a disposed on the outer peripheral portion of the pressure roller 64a as shown in FIG. The present inventors have found that a color filter substrate that does not have uneven stripes 8 that are uneven shading can be manufactured stably over a long period of time.

  Table 1 shows the result of determining the shading unevenness of each sample, which is the manufactured color filter substrate, by adjusting the static friction coefficient to a predetermined range.

  The linear pressure of the photosensitive sheet film 12 with respect to the axial direction of the pressure rollers 64a and 64b is 150 N / cm, the conveyance speed of the photosensitive sheet film 12 and the glass substrate 14 by the pressure rollers 64a and 64b is 1.4 m / minute, and the pressure roller 64a. , 64b, a contact temperature of the photosensitive sheet film 12 applied to the outer periphery of the pressure roller 64a, a heating temperature of the glass substrate 14 by the substrate heating unit 66 of the substrate transport mechanism 62, a glass substrate 14 Size, width 550 mm × length 650 mm × thickness 0.7 mm, and tension 140 N / width 550 mm of the photosensitive sheet film 12.

  Further, as shown in FIG. 4, the static friction coefficient is applied to the photosensitive sheet film 12 so as to abut on the outer peripheral surface in the range of the central angle of 90 ° of the pressure roller 64a held in a non-rotating state, and the photosensitive sheet having a width of 550 mm. A weight W having a weight that gives a tension of 140 N to the photosensitive sheet film 12 is connected to one end portion, a box body 59 is connected to the other end portion of the photosensitive sheet film 12, and pellets 61 are put into the box body little by little. The weight was calculated from the total weight of the box 59 and the pellet 61 when the weight W was lifted and the weight of the weight W.

  In this case, when the coefficient of static friction was set in the range of 1.0 or more or 0.7 or less, good results with no shading were obtained in any sample. In addition, when the static friction coefficient was set in the range of 0.9 to 1.0 or 0.7 to 0.8, a result that was somewhat poor depending on the sample was obtained. Further, when the coefficient of static friction was set in the range of 0.8 to 0.9, a failure result in which unevenness in density was a problem in any sample was obtained.

  Based on the above results, the applicant of the present invention presumed that the shading unevenness generated in the photosensitive sheet film 12 pressure-bonded to the glass substrate 14 occurs due to the following reasons.

  That is, at the beginning of transfer by a new pressure roller 64a covered with a rubber layer 65a having a static friction coefficient of 1.0 or more, there is no occurrence of shading, but the cumulative value of the number of transferred sheets increases and the static friction coefficient increases. Is in the range of 0.8 to 0.9, the density unevenness occurs, and when the transfer is continued and the static friction coefficient becomes 0.7 or less, the density unevenness does not occur again (see the solid line in FIG. 5). .

  From this phenomenon, when the surface of the rubber layer 65a coated on the pressure roller 64a is new, the coefficient of static friction is large, so that there is no slip between the base film 16 of the photosensitive sheet film 12 and the rubber layer 65a. It is considered that the film 12 is transported at a stable transport speed and unevenness in density does not occur.

  On the other hand, when the transfer is repeated, the coefficient of static friction gradually decreases due to the fact that a material such as the base film 16 or an acrylic primer containing an antistatic agent applied thereto adheres to the rubber layer 65a. In the range of the static friction coefficient, intermittent slippage between the base film 16 and the rubber layer 65a, so-called stick-slip phenomenon occurs. This stick-slip phenomenon is caused by the influence of the bulge portion (see FIG. 8) generated by deformation of the rubber layers 65a and 65b when the photosensitive sheet film 12 and the glass substrate 14 are pressed by the pressure rollers 64a and 64b. It is considered that intermittent slip occurs between the photosensitive sheet film 12 and the photosensitive sheet film 12, and unevenness of density occurs in the photosensitive sheet film 12.

  Further, when the transfer is repeated, the static friction coefficient between the base film 16 and the rubber layer 65a becomes small and the stick-slip phenomenon does not occur, and the photosensitive sheet film 12 is conveyed again at a stable conveyance speed. It is considered that the occurrence of shading unevenness is eliminated.

  Therefore, it is conceivable that maintenance such as replacement and polishing of the rubber layer 65a is frequently performed and the static friction coefficient of the rubber layer 65a with respect to the base film 16 is maintained at 1.0 or more as shown by a dotted line in FIG. In this case, it is obvious that the production efficiency is remarkably lowered and the cost is increased.

  By setting the coefficient of static friction between the base film 16 and the rubber layer 65a to be in the range of 0.1 to 0.7 from the beginning, as shown by the two-dot chain line in FIG. In addition, the photosensitive sheet film 12 and the glass substrate 14 are transported in a stable state for a long period of time without lowering the production efficiency, without replacing the rubber layer 65a, cleaning, polishing, etc. It was found that the transfer process can be repeated at low cost.

  Further, as a comparative example, when the static friction coefficient between the rubber layer 65a and the photosensitive sheet film 12 is set to 0.95, the transfer process is performed by changing the tension of the photosensitive sheet film 12, and the unevenness of light and shade is removed. The determined results are shown in Table 2.

  In this case, assuming that the coefficient of static friction is 0.95, when a tension of 120 N / 550 mm or more is applied, a result in which shading unevenness appears in any sample is obtained.

  On the other hand, when the coefficient of static friction was set to 0.6, good results with no shading were obtained in any case of tension of 100 N / 550 mm or more. Note that by setting the tension on the photosensitive sheet film 12 high, generation of wrinkles and mixing of bubbles can be suitably avoided.
