Description

  The present invention relates to a photosensitive web bonding apparatus and method for bonding a photosensitive web having at least a photosensitive material layer laminated on a support to the substrate such that the photosensitive material layer side faces the substrate.

  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 material (photosensitive resin) layer to the substrate surface. In the photosensitive sheet body, a photosensitive material layer and a protective film are sequentially laminated on a flexible plastic support.

  In view of this, a pasting apparatus used for pasting this type of photosensitive sheet body usually transports substrates such as a glass substrate and a resin substrate spaced apart from each other by a predetermined interval, and also a photosensitive unit pasted on the substrate. In accordance with the range of the material layer, a method of peeling the protective film from the photosensitive sheet body is adopted.

  For example, in the film sticking method and apparatus disclosed in Patent Document 1, as shown in FIG. 10, a laminate film (photosensitive sheet) 1a fed out from a film roll 1 is wound around guide rolls 2a and 2b. And extend along a horizontal 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 roll 2b.

  A laminate film 1a extending along a horizontal film transport surface is wound around a suction roll 4, and a half cutter 5 and a cover film peeling device 6 are interposed between the guide roll 2b and the suction roll 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 winds the adhesive tape 7 a fed out from the adhesive tape roll 7 strongly to the cover film between the pressing rolls 8 a and 8 b, 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 roll 4, lamination rolls 12 a and 12 b are provided for laminating and laminating the laminate 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. . A support film take-up roll 13 is disposed downstream of the lamination rolls 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 Patent Document 1 described above, for example, the lamination roll 12a is driven to rotate, and the lamination roll 12b is driven at a constant pressure, and the substrate 11 and the laminate film 1a are heated and sandwiched to perform lamination. .

  At that time, the substrate 11 is laminated with the laminate film 1a so as to be separated from each other by a predetermined distance in order to prevent damage or the like due to mutual overlap. For this reason, for example, by laminating the lamination roll 12b and separating it from the lamination roll 12a correspondingly between the substrates 11, only the laminated film 1a is conveyed corresponding to a constant interval.

  Here, in the lamination roll 12b, the rotational balance is lost due to the processing accuracy of the lamination roll 12b itself, the thermal deformation by the heater (not shown) provided in the lamination roll 12b, the configuration of the heater itself, and the like. There are many cases.

  Therefore, when the lamination roll 12b is lowered, the lamination roll 12b rotates (spins). For this reason, while the substrate 11 to be laminated next is conveyed to the laminating position, when the lamination roll 12b is raised, the position of the substrate 11 becomes unstable due to the frictional force caused by the rotation of the lamination roll 12b. There's a problem. As a result, there is a problem in that the laminated film 1a cannot be accurately attached to a desired position of the substrate 11 and an attachment failure occurs.

  It is also conceivable to wait until the rotation generated when the lamination roll 12b is lowered and the lamination roll 12b stops and to laminate the next substrate 11 and the laminate film 1a. However, as a result, the production tact time becomes considerably long, and there is a problem that the thermal polymerization performance of the laminate film 1a itself is greatly affected.

  SUMMARY OF THE INVENTION The present invention solves this type of problem, and provides a photosensitive web bonding apparatus and method capable of performing a high-quality laminating process satisfactorily and efficiently with a simple configuration and process. The purpose is to provide.

And a driven roller that advances and retreats with respect to the roller. The driven roller is provided with a brake mechanism, and the brake mechanism restricts the rotation of the driven roller at least when the driven roller moves back and forth.

  The brake mechanism preferably includes a powder brake and a belt member attached to the powder brake and the driven roller.

  Furthermore, the brake mechanism includes a slide portion that holds the powder brake so that the powder brake can advance and retreat, and an actuator that adjusts the braking force applied to the driven roller by moving the powder brake along the slide portion. Is preferred.

  In addition, the present invention provides a method for attaching a photosensitive web to which the photosensitive web is attached to the substrate by sandwiching the photosensitive web having at least a photosensitive material layer on the support and the substrate by a pair of laminating rollers. It is related to the attaching method.

  The affixing method comprises a pair of laminating rollers, a driving side roller connected to a rotation driving source and rotating, and a driven side roller which is rotatable and moves back and forth with respect to the driving side roller. A step of moving the driven roller in a direction away from the driving roller while the rotation of the driven roller is restricted, and a new substrate corresponding to the photosensitive web The driven roller that is restricted in rotation is moved toward the driving roller, and the new substrate and the photosensitive member are moved by the driving roller and the driven roller that is restricted in rotation. A step of clamping the photosensitive web, and after releasing the rotation restriction of the driven side roller, the new substrate and the photosensitive web are rotated under the rotational action of the driving side roller. And a step of performing lamination.

  In the present invention, when the driven roller advances and retreats, the rotation of the driven roller is restricted under the action of the brake mechanism. Then, after the substrate and the photosensitive web are sandwiched between the driving side roller and the driven side roller, the rotation restriction of the driven side roller by the brake mechanism is released.

  For this reason, it is possible to prevent the driven roller from rotating (spinning) unnecessarily and causing the positional deviation of the substrate, so that the substrate can be accurately arranged at a desired position, and the pasting accuracy is effectively improved. . In addition, the manufacturing tact time is shortened, the efficiency of the entire manufacturing operation can be easily performed, and the thermal polymerization performance of the photosensitive web can be prevented from being affected.

  The half-cut portions 34a and 34b need to cut at least the protective film 30 and the photosensitive resin layer 28, and the cutting depths of the round blades 52a and 52b are set so as to cut into the flexible base film 26 in practice. The The round blades 52a and 52b are fixed without rotating, and move in the width direction of the long photosensitive web 22 to form the half-cut portions 34a and 34b, or the long photosensitive web. A method of moving in the width direction while rotating without sliding on 22 to form the half-cut portions 34a and 34b is adopted.

  When the photosensitive resin layer 28 is attached to the glass substrate 24, the half-cut portions 34a and 34b are set, for example, so as to be in a position that enters into the inside by 10 mm from both ends of the glass substrate 24, respectively. The remaining portion B of the protective film 30 between the glass substrates 24 functions as a mask when the photosensitive resin layer 28 is attached to the glass substrate 24 in a frame shape in the attaching mechanism 46 described later.

  Since the label adhesion mechanism 40 leaves the remaining part B of the protective film 30 correspondingly between the glass substrates 24, an adhesive label that connects the peeling part A on the half-cut part 34b side and the peeling part A on the half-cut part 34a side. 38 is supplied.

  As shown in FIG. 3, the adhesive label 38 is formed in a strip shape, and is formed of, for example, the same resin material as the protective film 30.

The dancer roller 60 is provided.

  The peeling mechanism 44 disposed downstream of the reservoir mechanism 42 includes a suction drum 62 that blocks tension fluctuation on the delivery side of the long photosensitive web 22 and stabilizes the tension during lamination. A peeling roller 63 is disposed in the vicinity of the suction drum 62, and the protective film 30 peeled off from the long photosensitive web 22 with an acute peeling angle via the peeling roller 63 except for the remaining portion B. Then, the film is wound around the protective film winding section 64.

  A tension control mechanism 66 that can apply tension to the long photosensitive web 22 is disposed on the downstream side of the peeling mechanism 44. The tension control mechanism 66 can adjust the tension of the long photosensitive web 22 when the tension dancer 70 swings and displaces under the driving action of the cylinder 68. The tension control mechanism 66 may be used as necessary and can be deleted.

And a stop position detection sensor 78 for detecting the stop position of the rear 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 a laminating roller pair 80 that sandwiches and laminates the long photosensitive web 22 and the glass substrate 24. As shown in FIGS. 4 and 5, the laminating roller pair 80 includes a driving-side rubber roller 80a that is connected to a motor 82 that is a rotational driving source and rotates, and a driven member that is rotatable and that moves forward and backward with respect to the driving-side rubber roller 80a.

  Backup rollers 84a and 84b are in sliding contact with the driving side rubber roller 80a and the driven side rubber roller 80b, and the backup roller 84b is pressed against the driven side rubber roller 80b via the roller clamp portion 86.

  As shown in FIG. 4, the roller clamp portion 86 includes a drive motor 88, and a ball screw 92 is attached to a drive shaft 90 a of a reduction gear 90 connected to the drive shaft of the drive motor 88. A nut member 94 is screwed onto the ball screw 92, and the nut member 94 is fixed to the slide base 96. Tapered cams 97a and 97b are fixed to both ends of the slide base 96 in the web width direction (arrow Z direction). The heights of the taper cams 97a and 97b are set so as to increase toward the arrow Z1 direction. Rollers 98a and 98b are placed on the taper cams 97a and 97b, and these rollers 98a and 98b are held below the pressure cylinders 100a and 100b.

  Support plates 104a and 104b are abutted and supported by rods 102a and 102b extending upward from the pressure cylinders 100a and 100b. Both end shafts of the driven rubber roller 80b and the backup roller 84b are rotatably supported by the support plates 104a and 104b by bearings (not shown).

  As shown in FIG. 5, the driven-side rubber roller 80b is provided with a brake mechanism 106 that restricts the rotation of the driven-side rubber roller 80b at least when the driven-side rubber roller 80b moves back and forth in the vertical direction. The brake mechanism 106 includes a powder brake 112 that is disposed on the base 108 and is movable forward and backward in the direction of arrow C via the slide portion 110. The powder brake 112 and the driven rubber roller 80b are connected via a belt member 114, and the powder brake 112 can apply a braking force to the driven rubber roller 80b.

  A cylinder (actuator) 118 is mounted on the base 108, and a rod 118 a extending from the cylinder 118 in the direction of arrow C is connected to the powder brake 112. By urging the rod 118a in the direction of the arrow C1, the cylinder 118 is fixed to the belt member 114 stretched between the powder brake 112 and the driven rubber roller 80b even when the driven rubber roller 80b moves up and down. Tension can be applied. The slide part 110 has a function of adjusting the inter-axis distance when the driven-side rubber roller 80b moves back and forth in the vertical direction.

  As shown in FIG. 1, the glass substrate 24 is transported from a pasting mechanism 46 via a transport path 120 that extends in the arrow Y direction. In the conveyance path 120, film conveyance rollers 122a and 122b and a substrate conveyance roller 124 are disposed. It is preferable that the distance between the driving side rubber roller 80 a and the driven side rubber roller 80 b and the substrate transport roller 124 is set to be equal to or less than the length of one glass substrate 24.

  In the manufacturing system 20, the web feed mechanism 32, the processing mechanism 36, the label bonding mechanism 40, the reservoir mechanism 42, the peeling mechanism 44 and the tension control mechanism 66 are disposed above the attaching mechanism 46, but this is not the case. Further, the web feeding mechanism 32 to the tension control mechanism 66 are arranged below the attaching mechanism 46, and the photosensitive resin layer 28 is attached to the glass substrate 24 by turning the long photosensitive web 22 upside down. The configuration may be affixed to the lower side, or the conveyance path of the long photosensitive web 22 may be configured linearly.

  The interior of the manufacturing system 20 is partitioned into a first clean room 162a and a second clean room 162b through a partition wall 160. The first clean room 162a and the second clean room 162b communicate with each other through the penetration part 164. The manufacturing system 20 is controlled via the control unit 166.

  The operation of the manufacturing system 20 configured as described above will be described in relation to the attaching method according to the present embodiment.

  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. As a result, half-cut portions 34a and 34b that are separated by the width M of the remaining portion B of the protective film 30 are formed, and the long photosensitive web 22 has a rear portion A and a rear portion sandwiching the remaining portion B. The peeling portion A is provided (see FIG. 2).

  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 bonding mechanism 40, a predetermined number of adhesive labels 38 are sucked and held by the suction pads 54b to 54g. Each adhesive label 38 is integrally bonded to the front peeling portion A and the rear peeling portion A across the remaining portion B of the protective film 30 (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, the long photosensitive web 22 is transported to the affixing mechanism 46 so that the photosensitive resin layer 28 is thermally transferred (laminated) to the glass substrate 24. In the pasting mechanism 46, the driving-side rubber roller 80a and the driven-side rubber roller 80b are set in advance in a separated state. Then, the conveyance of the long photosensitive web 22 is temporarily stopped in a state where the half cut portion 34a of the long photosensitive web 22 is positioned at a predetermined position between the driving side rubber roller 80a and the driven side rubber roller 80b. The

  In this state, as shown in FIG. 4, when the ball screw 92 rotates in a predetermined direction under the action of the speed reducer 90 connected to the drive motor 88, the nut member 94 that is screwed into the ball screw 92 is integrated. The slide base 96 moves in the direction of arrow Z2. For this reason, the taper cams 97a and 97b have higher contact surfaces with the rollers 98a and 98b, and displace the rollers 98a and 98b upward. Accordingly, the pressure cylinders 100a and 100b are raised, and the backup roller 84b and the driven rubber roller 80b are raised.

  As a result, the glass substrate 24 is sandwiched between the driving-side rubber roller 80a and the driven-side rubber roller 80b with a predetermined pressing pressure. At that time, the press pressure is adjusted by the air pressure of the pressurizing cylinders 100a and 100b. Further, the drive-side rubber roller 80a rotates via the motor 82, whereby the photosensitive resin layer 28 is thermally transferred (laminated) to the glass substrate 24 by heating and melting.

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

  When the lamination of one long photosensitive web 22 on the glass substrate 24 is completed, the rotation of the driving side rubber roller 80a and the driven side rubber roller 80b is stopped. On the other hand, as shown in FIG. 1, the front end portion of the photosensitive laminate 170 that is the glass substrate 24 on which the long photosensitive web 22 is laminated is clamped by the substrate transport roller 124. At this time, a half cut portion 34b is disposed at a predetermined position between the driving side rubber roller 80a and the driven side rubber roller 80b.

  Then, the driven-side rubber roller 80b is retracted in a direction away from the driving-side rubber roller 80a, and the clamp is released. Specifically, as shown in FIG. 4, the speed reducer 90 connected to the drive motor 88 is rotationally driven in the opposite direction to the above, and the slide base 96 is moved in the direction of the arrow Z1 via the ball screw 92 and the nut member 94. Move to. For this reason, the taper cams 97a and 97b have lower surfaces that contact the rollers 98a and 98b, and the pressure cylinders 100a and 100b are lowered. As a result, the backup roller 84b and the driven rubber roller 80b are lowered to release the clamp.

  Next, as shown in FIG. 1, the rotation of the substrate transport roller 124 is started again at a low speed. The photosensitive laminate 170 was conveyed in the arrow Y direction by a distance corresponding to the width M of the remaining portion B of the protective film 30, and the next half-cut portion 34a was conveyed to a predetermined position near the lower side of the driving side rubber roller 80a. Thereafter, the rotation of the drive-side rubber roller 80a is stopped.

  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 170 is continuously manufactured.

  The photosensitive laminate 170 laminated by the attaching mechanism 46 is separated by cutting the long photosensitive web 22 between the glass substrates 24 by the cutting mechanism 48. The separated photosensitive laminate 170 is provided with a flexible base film 26. After the flexible base film 26 is peeled off together with the protective film 30 between the glass substrates 24, the next processing step is performed. Supplied.

  In this case, in the above-described laminating process, as shown in FIG. 6, the accuracy of the bonding position between each glass substrate 24 and the long photosensitive web 22 is set in advance. In other words, the half-cut portion 34a is set at a position spaced inward by a distance S1 from the front end portion in the transport direction of each glass substrate 24, and the half-cut portion 34b is formed from the rear end portion in the transport direction of each glass substrate 24. The position is set inwardly by a distance S2. Furthermore, the distance S3 from the width direction both ends of the long photosensitive web 22 to the width direction both ends of each glass substrate 24 is set.

  Accordingly, it is necessary to perform the laminating process so that the distances S1 to S3 are maintained within a preset range. When the half-cut portions 34 a and 34 b protrude from the glass substrate 24 b, when the long photosensitive web 22 is peeled from the glass substrate 24, the material applied to the long photosensitive web 22 is the glass substrate 24. There is a risk of adhering to the end face. As a result, for example, the paste protrudes from the end face of the glass substrate 24, and quality deterioration due to adhesion of dust or the like is caused in the downstream exposure process or development process.

  Therefore, in the first embodiment, as shown in FIG. 5, the brake mechanism 106 is attached to the driven rubber roller 80 b that is rotatable and can be advanced and retracted with respect to the driving rubber roller 80 a via the roller clamp portion 86. .

  Therefore, as shown in FIG. 7, when the driven rubber roller 80 b is lowered integrally with the backup roller 84 b via the roller clamp portion 86, the driven rubber roller 80 b and the powder brake 112 are connected via the belt member 114. The rotation of the driven rubber roller 80b is restricted under the action of the powder brake 112.

  Next, under the action of the motor 82, the driving-side rubber roller 80a rotates to feed the long photosensitive web 22 in the arrow Y direction, and the glass substrate 24 is conveyed in the arrow Y direction. And if the front-end | tip of the glass substrate 24 is arrange | positioned in the position corresponding to the driven side rubber roller 80b, the said driven side rubber roller 80b will raise.

  The driven-side rubber roller 80b is subjected to a rotation restricting force (braking force) by the powder brake 112. The driven-side rubber roller 80b rises in a state where rotation (spinning) is suppressed and is pressed against the glass substrate 24. (See FIG. 5).

  Next, as shown in FIG. 8, the powder brake 112 cancels the rotation restriction of the driven rubber roller 80b. Therefore, when the drive-side rubber roller 80a is rotationally driven under the drive action of the motor 82, the long photosensitive web 22 is laminated on the glass substrate 24 via the drive-side rubber roller 80a and the driven-side rubber roller 80b. Is done.

  Thereby, in 1st Embodiment, when the driven side rubber roller 80b advances / retreats, it can prevent reliably rotating with the eccentric force of this driven side rubber roller 80b itself. Therefore, for example, the rotating driven-side rubber roller 80b does not rise and contact the glass substrate 24, and the glass substrate 24 is prevented from being displaced as much as possible, so that the glass substrate 24 is moved to a desired position. It becomes possible to arrange accurately. For this reason, the effect that the pasting precision of the glass substrate 24 and the elongate photosensitive web 22 improves effectively is acquired.

  In addition, the driven-side rubber roller 80b can be quickly moved up and down, and the manufacturing tact of the photosensitive laminate 170 is greatly reduced. Therefore, it is possible to easily improve the efficiency of the entire manufacturing operation, maintain the thermal polymerization performance of the long photosensitive web 22, and favorably prevent deterioration in quality. There is.

  Further, the brake mechanism 106 uses a powder brake 112. For this reason, according to the contact friction between the glass substrate 24 and the driven roller 80b, the driven rubber roller 80b can be moderately braked during lamination. As a result, it is possible to satisfactorily control the elongation and the state of the pasting surface when the long photosensitive web 22 is pasted.

  In the first embodiment, the driven rubber roller 80b and the powder brake 112 are connected by the belt member 114, and the powder brake 112 is separated from the driven rubber roller 80b by the elastic force of the spring 116. That is, although it is pressed in the direction of restricting rotation, it is not limited to this.

  For example, you may comprise the powder brake 112 so that it may always be urged | biased by the arrow C1 direction via a spring (not shown). Further, a brake mechanism (not shown) is directly attached to the shaft portion of the driven side rubber roller 80b. When the driven side rubber roller 80b moves up and down, the rotation is restricted. You may comprise so that regulation may be cancelled | released.

  FIG. 9 is a schematic configuration diagram of a photosensitive laminate manufacturing system (sticking apparatus) 180 according to the second embodiment of the present invention. Note that the same components as those in the manufacturing system 20 according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The manufacturing system 180 includes a cooling mechanism 182 downstream of the attaching mechanism 46 and a base automatic peeling mechanism 184 disposed on the downstream side of the cooling mechanism 182. The cooling mechanism 182 supplies cold air to the laminated photosensitive laminate 170 to perform a cooling process.

  The automatic base peeling mechanism 184 continuously peels the long flexible base film 26 to which the glass substrates 24 are attached at predetermined intervals, and the pre-peeling portion 186 is relatively A small-diameter peeling roller 188, a winding shaft 190, and an automatic pasting machine 192 are provided.

  The take-up shaft 190 controls the torque during driving to apply tension to the flexible base film 26, while performing tension feedback control by providing a tension detector (not shown) on the peeling roller 188, for example. It is preferable. The pre-peeling portion 186 includes a peeling bar 194 that can move up and down between the glass substrates 24.

  In the second embodiment configured as described above, the photosensitive laminate 170 laminated by the attaching mechanism 46 is cooled through the cooling mechanism 182 and then transferred to the pre-peeling portion 186. In the pre-peeling portion 186, the protective film 30 can be peeled off from the rear end and the front end of the adjacent glass substrate 24 by raising the peeling bar 194.

  Next, in the base automatic peeling mechanism 184, the flexible base film 26 is continuously wound from the photosensitive laminate 170 under the rotating action of the winding shaft 190. Further, after separation at the time of trouble stop or cutting at the time of defective product separation, the leading end of the flexible base film 26 of the photosensitive laminate 170 which has been newly laminated and the winding shaft 190 are wound up. The flexible base film 26 is automatically attached to the rear end of the flexible base film 26 via an automatic attaching machine 192.
