Description

  In the present invention, a substrate and a long photosensitive web provided with a photosensitive material layer on a support are synchronized and fed between a pair of pressure rollers, and the photosensitive material layer is attached to the substrate to be photosensitive. The present invention relates to a manufacturing apparatus and a manufacturing method for a photosensitive laminate for producing a conductive laminate.

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

  A manufacturing apparatus used for attaching this type of photosensitive sheet body usually conveys a glass substrate or a resin substrate such as a glass substrate or a resin substrate spaced apart from each other by a predetermined distance, and a photosensitive resin layer attached to the substrate. Corresponding to this range, a method of peeling the protective film from the photosensitive sheet body is adopted.

  For example, in the manufacturing apparatus disclosed in Patent Document 1, as shown in FIG. 10, a laminate film (photosensitive sheet body) 1 a fed out from a film roll 1 is wound around guide rollers 2 a and 2 b to be horizontal. It extends along the film transport surface. A rotary encoder 3 that outputs a number of pulse signals corresponding to the feed amount of the laminated film 1a is attached to the guide roller 2b.

  A laminate film 1a extending along a horizontal film transport surface is wound around a suction roller 4, and a half cutter 5 and a cover film peeling device 6 are interposed between the guide roller 2b and the suction roller 4. And are provided.

  The half cutter 5 includes a pair of disk cutters 5a and 5b. The disc cutters 5a and 5b move along the film width direction of the laminated film 1a, so that the cover film (not shown) of the laminated film 1a is replaced with a photosensitive resin layer (not shown) on the back side thereof. Cut it together.

  The cover film peeling apparatus 6 strongly presses the adhesive tape 7a fed out from the adhesive tape roll 7 to the cover film between the pressing rollers 8a and 8b, and then winds it by the take-up roll 9. As a result, the cover film is peeled off from the photosensitive resin layer and wound around the winding roll 9 together with the adhesive tape 7a.

  Downstream of the suction roller 4, a pair of lamination rollers 12 a and 12 b are arranged to stack and press the laminated film 1 a on the upper surfaces of a plurality of substrates 11 that are sequentially and intermittently conveyed by the substrate conveying device 10. ing. A support film take-up roll 13 is disposed downstream of the lamination rollers 12a and 12b. A translucent support film (not shown) attached to the substrate 11 is taken up by a support film take-up roll 13.

Japanese Patent Laid-Open No. 11-34280 (FIG. 1)

  By the way, in such a manufacturing apparatus, the time required to apply the photosensitive resin layer of the laminate film 1a to the substrate 11 is restricted by the takt time of the entire manufacturing apparatus including the processing steps after the application. Therefore, in the manufacturing apparatus, the rotational speeds of the lamination rollers 12a and 12b are set in consideration of the tact time.

  However, when a large number of photosensitive laminates are continuously manufactured, the characteristics of the lamination rollers 12a and 12b and the laminate film 1a are not always constant. For example, the friction coefficient of the surfaces of the lamination rollers 12a and 12b is If it changes, since slip occurs between the laminated film 1a and the lamination rollers 12a and 12b, the time required for attachment may vary. In addition, when the time required for pasting varies, there is a concern that variations in quality occur between the manufactured photosensitive laminates.

  The present invention solves this type of problem, and adjusts the time required for pasting within the tact time to produce a photosensitive laminate that can produce a high-quality photosensitive laminate without unevenness. An object is to provide an apparatus and a manufacturing method.

In the present invention, a substrate and a long photosensitive web provided with a photosensitive material layer on a support are synchronized and fed between a pair of pressure rollers, and the photosensitive material layer is attached to the substrate to be photosensitive. In the manufacturing apparatus and manufacturing method of the photosensitive laminated body which manufactures a conductive laminate,
The rotational speed of one of the pressure-bonding rollers in contact with the support is set to be higher by a predetermined amount than the rotational speed based on the takt time for manufacturing the photosensitive laminate.

  In this case, by setting the ratio g between the rotation speed of the one pressure roller and the rotation speed based on the tact time in the range of 1.0 <g ≦ 1.017, the tact time is exceeded. A photosensitive laminate can be produced without doing so.

  The ratio g is set based on the static friction coefficient μ of the one pressure roller with respect to the support, so that the time required for manufacturing the photosensitive laminate is constant regardless of the change of the static friction coefficient μ. Can be within the range. In this case, the static friction coefficient μ is preferably set in the range of 0.15 ≦ μ ≦ 1.8.

  The rotation speed of the pressure roller may be adjusted based on the time required for adhering the photosensitive material layer to the substrate.

  In the present invention, by adjusting the rotation speed of the pressure roller in contact with the support of the long photosensitive web, the time required for adhering to the substrate is within the tact time for manufacturing the photosensitive laminate. In addition, the time required for the production of each photosensitive laminate can be stabilized, and a high-quality photosensitive laminate with no unevenness can be continuously produced.

The mechanisms 47a and 47b and thereafter are accommodated. The first clean room 112a and the second clean room 112b communicate with each other through the penetration part 114.

  The operation of the manufacturing apparatus 20 configured as described above will be described below in relation to the manufacturing method according to the present invention.

  First, the photosensitive webs 22a and 22b are sent out from the respective photosensitive web rolls 23a and 23b attached to the first and second web delivery mechanisms 32a and 32b. The photosensitive webs 22a and 22b are conveyed to the first and second processing mechanisms 36a and 36b.

  In the first and second processing mechanisms 36a and 36b, the round blade 52 moves in the width direction of the photosensitive webs 22a and 22b, and the photosensitive webs 22a and 22b are moved from the protective film 30 to the photosensitive resin layer 28 to the base film. Cut to 26 to form a half-cut portion 34 (see FIG. 2). Further, as shown in FIG. 1, the photosensitive webs 22a and 22b are stopped after being transported in the direction of the arrow A corresponding to the dimension of the remaining portion 30b of the protective film 30, and the half-blade 52 is halfway under the traveling action. A cut site 34 is formed. Thus, the photosensitive webs 22a and 22b are provided with a front peeling portion 30aa and a rear peeling portion 30ab with the remaining portion 30b interposed therebetween (see FIG. 2).

  Next, the respective photosensitive webs 22 a and 22 b are conveyed to the first and second label adhering mechanisms 40 a and 40 b, and a predetermined application site of the protective film 30 is arranged on the cradle 56. In the first and second label adhering mechanisms 40a and 40b, 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 30b of the protective film 30, and a front peeling portion. 30aa and the rear peeling portion 30ab are integrally bonded (see FIG. 3).

  For example, the photosensitive webs 22a and 22b to which the seven adhesive labels 38 are bonded, as shown in FIG. 1, after the first and second reservoir mechanisms 42a and 42b are prevented from changing the tension on the delivery side, It is continuously conveyed to the first and second peeling mechanisms 44a and 44b. In the first and second peeling mechanisms 44a and 44b, as shown in FIG. 5, the base film 26 of the photosensitive webs 22a and 22b is adsorbed and held by the suction drum 62, and the protective film 30 leaves the remaining portion 30b. It peels from the said photosensitive webs 22a and 22b. 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 first and second peeling mechanisms 44a and 44b, after the protective film 30 is peeled from the base film 26 leaving the remaining portion 30b, the photosensitive webs 22a and 22b are moved to the first and second tension control mechanisms. The tension is adjusted by 66a and 66b, and the half-cut portion 34 is detected by the photoelectric sensors 72a and 72b by the first and second detection mechanisms 47a and 47b.

  Each photosensitive web 22a, 22b is quantitatively transported to the affixing mechanism 46 under the rotational action of the film transport rollers 90a, 90b based on the detection information of the half-cut region 34, respectively. On the other hand, the glass substrate 24 is transported to the affixing position in a heated state under the action of the substrate transport mechanism 45. The glass substrate 24 is temporarily disposed between the rubber rollers 80a and 80b corresponding to the portion where the photosensitive resin layer 28 of the photosensitive webs 22a and 22b arranged in parallel is attached.

  In this state, by raising the backup roller 82b and the rubber roller 80b, the glass substrate 24 is sandwiched between the rubber rollers 80a and 80b with a predetermined pressing pressure. Further, the photosensitive resin layers 28 arranged in parallel are transferred (laminated) to the glass substrate 24 under the rotating action of the rubber roller 80a as shown in FIG.

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

  Further, as a laminating condition, a static friction coefficient μ of the upper rubber roller 80a contacting the flexible base film 26 of the photosensitive webs 22a and 22b with respect to the flexible base film 26 is 0.15 ≦ μ ≦ 1.8. Set the range. By setting the static friction coefficient μ within this range, it is possible to avoid a situation where bubbles are mixed between the glass substrate 24 and the photosensitive resin layer 28 or a situation where a non-uniform pasting state occurs.

  Furthermore, as a laminating condition, the upper rubber roller 80a has a rotational speed based on the overall tact time of the manufacturing apparatus 20 that manufactures the photosensitive laminate in which the photosensitive resin layer 28 is bonded to the glass substrate 24. By setting the rotation speed to be faster in the range of ratio g satisfying 1.0 <g ≦ 1.017, a high-quality photosensitive laminate is produced in a time within the tact time, as will be described later. be able to.

  When the lamination of one photosensitive web 22a, 22b is completed on the glass substrate 24 via the rubber rollers 80a, 80b, the rotation of the rubber roller 80a is stopped, while the photosensitive webs 22a, 22b are laminated. A glass substrate 24 (hereinafter also referred to as a bonded substrate 24 a) is clamped by a substrate transport roller 92.

  Then, the rubber roller 80b is retracted in the direction away from the rubber roller 80a to release the clamp, and the rotation of the substrate transport roller 92 is started, so that the bonded substrate 24a is quantitatively transported in the direction of arrow C, and the photosensitive web. The position between the substrates 22a and 22b moves to a predetermined position near the lower side of the rubber roller 80a. On the other hand, the next glass substrate 24 is transported toward the attaching position via the substrate transport mechanism 45.

  When the tip of the next glass substrate 24 is disposed between the rubber rollers 80a and 80b, the rubber roller 80b is raised, and the next glass substrate 24 and the photosensitive webs 22a and 22b are clamped by the rubber rollers 80a and 80b. Is done. Lamination is started under the rotational action of the rubber rollers 80a and 80b and the substrate transport roller 92, and the bonded substrate 24a is transported in the direction of arrow C.

  At that time, as shown in FIG. 6, the pasting substrate 24a is covered with the remaining portion 30b at each end. 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 pasted substrate 24 a laminated by the pasting mechanism 46 is cooled through the cooling mechanism 122 and then transferred to the pre-peeling portion 144. In the pre-peeling portion 144, the peeling bar 156 enters between the glass substrates 24 and rises, whereby the protective film 30 between the glass substrates 24 is lifted and peeled from the rear end and the leading end of the adjacent glass substrates 24. To do.

  Next, in the automatic base peeling mechanism 142, the base film 26 is continuously wound from the pasting substrate 24 a under the rotating action of the winding shaft 148. Further, after separation when trouble stops or separation when defective products are separated, the base film 26 wound on the winding shaft 148 and the tip of the base film 26 of the pasting substrate 24a which has been newly laminated are started. 26 is automatically pasted via the automatic pasting machine 150.

  The bonded substrate 24a from which the base film 26 has been peeled is placed at an inspection station corresponding to the measuring instrument 158. In this inspection station, images of the glass substrate 24 and the photosensitive resin layer 28 are captured by the camera 160 with the glass substrate 24 positioned and fixed. Then, by applying image processing, the pasting position is calculated.

  The attachment substrate 24 a on which the attachment position of the photosensitive resin layer 28 is confirmed is taken out by the robot 134 and accommodated in the photosensitive laminate stocker 132 as the photosensitive laminate 106.

  Here, the present applicant, as the laminating condition, has an upper limit with respect to the rotation speed based on the tact time of the manufacturing apparatus 20 that manufactures the photosensitive laminate in which the photosensitive resin layer 28 is bonded to the glass substrate 24. By setting the rotational speed of the rubber roller 80a to be faster in the range of the ratio g satisfying 1.0 <g ≦ 1.017, the high-quality photosensitive lamination can be performed within the tact time as follows. I found that I can make a body.

FIG. 7 shows the relationship between the time T from the start of attaching the photosensitive resin layer 28 to the glass substrate 24 and the feed amount L of the glass substrate 24 with respect to the flexible base film 26 of the rubber roller 80a. The coefficient of static friction μ and the ratio g of the rotational speed set to the rotational speed of the calculated rubber roller 80a capable of feeding the glass substrate 24 by the predetermined amount L ₀ as the pasting range at the tact time T ₀ are changed. The measurement results are shown.

In this case, even if the static friction coefficient μ = 1.8 and the ratio g = 1.0, that is, the rotational speed of the rubber roller 80a is set to an ideal rotational speed at which the pasting is completed at the tact time T ₀ , As a result, the time T _L required for the time is longer than the tact time T ₀ . This is because, for example, the static friction coefficient μ of the rubber roller 80a is large, so that the photosensitive webs 22a and 22b are stretched by the rubber roller 80a, and as a result, the time T until the pasting is completed also becomes long. Can be considered.

If the coefficient of static friction μ is 1.8 and the ratio g is 1.017, and the rotational speed of the rubber roller 80a is set faster than the ideal rotational speed at which the pasting is completed at the tact time T ₀ , the pasting is completed. A result is obtained in which the time T until the time coincides with the tact time T ₀ . Similarly, when the static friction coefficient μ = 0.15 and the ratio g = 1.0, a result in which the time T until the pasting is completed coincides with the tact time T ₀ is obtained. Further, when the static friction coefficient μ = 0.15 and the ratio g = 1.018, the result is that the time T until the pasting is completed is a time T _S shorter than the tact time T _0. Yes.

To summarize the above results, set faster rotational speed with respect to the ideal rotation speed of the paste is completed rubber rollers 80a in tact time T _0, also the static friction coefficient of the rubber roller 80a for the flexible base film 26 It is understood that the time T required for pasting can be shortened by reducing μ. Then, by setting the rotation speed ratio g and the static friction coefficient μ of the rubber roller 80a within the range indicated by hatching in FIG. 7, the pasting can be completed within a stable processing time within the tact time T ₀ . In this case, since the processing time is stabilized, a high-quality photosensitive laminate having no unevenness can be stably produced.

FIG. 8 shows the relationship between the static friction coefficient μ based on the above result and an appropriate ratio g that can be applied within the tact time T ₀ . In this case, the rubber roller 80a can be adjusted to an appropriate rotation speed using the laminate control unit 102 shown in FIG.

That is, the time from the start of lamination by the rubber roller 80a to the completion of the lamination until the substrate tip detection sensor 94 detects the tip of the glass substrate 24 is calculated by the laminate time calculation unit 105, and the calculated lamination time is rotated. This is supplied to the speed adjustment unit 107. When the rotational speed adjustment unit 107 determines that the lamination time may exceed the tact time T ₀ , the ratio g at which an appropriate lamination time can be obtained based on the static friction coefficient μ of the rubber roller 80a is shown in FIG. The rotational speed of the rubber roller 80a is adjusted according to the ratio g. As a result, the photosensitive laminate can be laminated in a stable processing time that does not exceed the tact time T ₀ .

  Note that the static friction coefficient μ supplied to the rotation speed adjustment unit 107 varies as the laminating process is continued. For example, the static friction coefficient μ is measured and supplied to the rotation speed adjustment unit 107 during regular maintenance. Is desirable.
