Description

  The present invention includes a long photosensitive web in which a photosensitive material layer and a protective film are sequentially laminated on a support, and the protective film is peeled at predetermined lengths, and the protective film is provided. The present invention relates to a manufacturing apparatus and a manufacturing method of a photosensitive laminate in which the photosensitive material layer exposed by peeling off is attached to a 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. 46, the laminated film 1a fed out from the film roll 1 is wound around the guide rolls 2a and 2b and is transported horizontally. It extends along the 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 6a.

  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.

  In this case, in Patent Document 1, counting of pulses generated from the rotary encoder 3 is started at the timing when the half cutter 5 starts cutting the laminated film 1a. When the counted value of the pulses generated by the rotary encoder 3 reaches a numerical value that reaches a specific point of the cutting line of the multilayer film 1a, the substrate transport device 10 is driven at that timing. Accordingly, the substrate 11 is fed between the lamination rolls 12a and 12b in synchronization with the laminate film 1a. As a result, the laminated film 1a and the substrate 11 are aligned with each other.

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

  In the above-mentioned Patent Document 1, counting of pulses generated by the rotary encoder 3 attached to the guide roll 2b is started from the cutting start timing by the half cutter 5. From this counted value, the half-cut portion is a lamination roll 12a, Assuming that a predetermined position between 12b has been reached, the substrate 11 is carried in.

  However, the pulse length from the half cutter 5 to the lamination rolls 12a and 12b is considerably long, and there is a possibility that the length of the laminated film 1a may change due to the heating of the lamination part, or the rotary encoder 3 may slip. is there.

To do. Further, the generation of dust and the upper part (first clean room 112a) and the lower part (second clean room 112b) where the dust is likely to fall are blocked, and particularly the cleanliness of the attaching mechanism 46 is ensured. In addition, it is desirable to set the pressure of the second clean room 112b to be higher than the pressure of the first clean room 112a to prevent dust from flowing into the second clean room 112b.

  As shown in FIG. 1, an air supply unit (not shown) for supplying clean air downward is disposed above the second clean room 112b.

  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, at the start of initial (cueing), the photosensitive web 22 is fed out from the photosensitive web roll 22a attached to the web feed mechanism 32. The photosensitive web 22 is sandwiched at the leading end by the film transport roller 90 through the processing mechanism 36, the label adhering mechanism 40, the reservoir mechanism 42, the peeling mechanism 44, and the attaching mechanism 46.

  Next, when the half-cut portion 34 is detected by the photoelectric sensor 72, the film transport roller 90 is rotationally driven based on this detection signal, and the photosensitive web 22 is quantitatively transported toward the attaching position. For this reason, the half-cut site | part 34 is positioned corresponding to a predetermined sticking position. Alternatively, the half cut portion 34 may be detected downstream of the attaching position, and the photosensitive web 22 may be stopped at a predetermined position.

  At that time, as shown in FIG. 6, the contact prevention roller 86 is lowered to prevent the photosensitive web 22 from contacting the rubber roller 80a. Further, the glass substrate 24 stands by immediately before the attaching position. Thereby, an initial start state is obtained.

  Next, the operation of each functional unit constituting the manufacturing apparatus 20 during the laminating operation will be described.

  First, as shown in FIG. 1, in the processing mechanism 36, the round blade 52 moves in the width direction of the photosensitive web 22, and this photosensitive web 22 is moved from the protective film 30 to the photosensitive resin layer 28 to the base film 26. A half-cut portion 34 is formed by cutting (see FIG. 2). Further, as shown in FIG. 1, the photosensitive web 22 is transported in the direction of arrow A corresponding to the size of the remaining portion 30b of the protective film 30, and then stopped and half-cut under the running action of the round blade 52. A site 34 is formed. Thus, the photosensitive web 22 is 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 photosensitive web 22 is conveyed to the label adhering mechanism 40, and a predetermined application portion of the protective film 30 is disposed 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 54e, and each adhering label 38 straddles the remaining portion 30b of the protective film 30, and the front peeling portion 30aa and the rear peeling portion 30ab. Are integrally bonded to each other (see FIG. 3).

  For example, as shown in FIG. 1, the photosensitive web 22 to which five adhesive labels 38 are bonded is continuously conveyed to the peeling mechanism 44 after the tension on the sending side is prevented via the reservoir mechanism 42. The In the peeling mechanism 44, as shown in FIG. 7, the base film 26 of the photosensitive web 22 is adsorbed and held by the suction drum 62, and the protective film 30 is peeled off from the photosensitive web 22 leaving a remaining portion 30b. . The protective film 30 is peeled off at an acute peeling angle via the peeling roller 63 and wound around the protective film take-up portion 64 (see FIG. 1).

  At this time, the photosensitive web 22 is firmly held by the suction drum 62, and an impact when the protective film 30 is peeled off from the photosensitive web 22 does not act on the downstream photosensitive web 22. Thereby, the impact of peeling is not transmitted to the attaching mechanism 46, and it is possible to satisfactorily prevent the occurrence of streak-like defective portions or the like in the laminated portion of the glass substrate 24.

  Under the action of the peeling mechanism 44, after the protective film 30 is peeled off from the base film 26 leaving the remaining portion 30b, the photosensitive web 22 is tension-adjusted by a tension control mechanism 66, and further the detection mechanism 47 performs photoelectric conversion. The sensor 72 detects the half-cut portion 34.

  The photosensitive web 22 is quantitatively transported to the pasting mechanism 46 under the rotational action of the film transport roller 90 based on the detection information of the half-cut portion 34. At that time, the contact prevention roller 86 waits upward, and the rubber roller 80b is disposed below.

  As shown in FIG. 8, the glass substrate 24 is transported to a pasting 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 web 22 is attached.

  In this state, as shown in FIG. 4, when the ball screw 94 rotates in a predetermined direction under the action of the speed reducer 93 a connected to the drive motor 93, the nut member 95 screwed into the ball screw 94 is integrated. The slide base 96 moves in the direction of arrow B2. 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 84a and 84b are raised and the backup roller 82b and the rubber roller 80b are raised, so that the glass substrate 24 is sandwiched between the rubber rollers 80a and 80b with a predetermined pressing pressure. At that time, the press pressure is adjusted by the air pressure of the pressurizing cylinders 84a and 84b. Further, the photosensitive resin layer 28 is transferred (laminated) to the glass substrate 24 by heating and melting under the rotating action of the rubber roller 80a.

  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 100 ° C to 150 ° C, the rubber hardness of the rubber rollers 80a and 80b is 40 ° to 80 °, The pressing pressure (linear pressure) of the rubber rollers 80a and 80b is 50 N / cm to 400 N / cm.

  As shown in FIG. 9, when the tip of the glass substrate 24 reaches the vicinity of the film transport roller 90, the film transport roller 90 moves away from the glass substrate 24. Further, when the front end of the photosensitive web 22 protruding forward (in the direction of arrow C) from the glass substrate 24 reaches a predetermined position with respect to the web front end cutting mechanism 48a, the web front end cutting mechanism 48a is driven to perform the photosensitive operation. The tip of the web 22 is cut. The web tip cutting mechanism 48a returns to the base standby position after cutting the tip of the photosensitive web 22, and is not used during normal operation.

  As shown in FIG. 10, when the lamination of one photosensitive web 22 is completed on the glass substrate 24 via the rubber rollers 80a and 80b, the rotation of the rubber roller 80a is stopped, while the photosensitive web 22 is laminated. The glass substrate 24 (hereinafter also referred to as a bonded substrate 24a) is clamped by the substrate transport roller 92.

  Then, the rubber roller 80b is retracted in a direction away from the rubber roller 80a, and the clamp is released. Specifically, as shown in FIG. 4, the speed reducer 93 a connected to the drive motor 93 is rotationally driven in the opposite direction to the above, and the slide base 96 is moved in the direction of arrow B <b> 1 via the ball screw 94 and the nut member 95. 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 84a and 84b are lowered. As a result, the backup roller 82b and the rubber roller 80b are lowered and the clamp is released.

  In this state, the rotation of the substrate transport roller 92 is started, the bonded substrate 24a is quantitatively transported in the direction of arrow C, and the inter-substrate position 22b of the photosensitive web 22 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 rises and the next glass substrate 24 and the photosensitive web 22 are clamped by the rubber rollers 80a and 80b. . At the same time, the substrate transport roller 92 clamps the bonded substrate 24a. Then, laminating is started under the rotating 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 (see FIG. 11).

  At that time, as shown in FIG. 12, 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 transfer can be performed in a frame shape.

  As shown in FIG. 13, when the substrate transport roller 92 reaches the rear end portion in the transport direction of the first bonded substrate 24a, the upper roller constituting the substrate transport roller 92 rises to release the clamp, The rotation of the lower roller and the conveyance path 88 is continued, and the affixing substrate 24a is conveyed. Further, when the rear end portion of the second bonded substrate 24a reaches the vicinity of the rubber rollers 80a and 80b, the rotation of the rubber rollers 80a and 80b and the substrate transport roller 92 is stopped. Then, the upper roller of the substrate transport roller 92 is lowered to clamp the second bonded substrate 24a, while the rubber roller 80b is lowered to release the clamp. Next, the second bonded substrate 24a is nipped and conveyed under the rotating action of the substrate conveying roller 92, the inter-substrate position 22b moves to a predetermined position near the lower side of the rubber roller 80a, and the third and subsequent laminating processes are performed. Repeated.

  As shown in FIG. 14, when the space between the bonded substrates 24a reaches a position corresponding to the inter-substrate web cutting mechanism 48, the inter-substrate web cutting mechanism 48 moves in the direction of arrow C at the same transport speed as the bonded substrate 24a. The photosensitive web 22 is cut between the pasting substrates 24a while moving to. After this cutting, the inter-substrate web cutting mechanism 48 is returned to a predetermined standby position, while the base film 26 and the remaining portion 30b are peeled off from the bonded substrate 24a to manufacture the photosensitive laminate 106.

  When the laminating process is temporarily stopped, as shown in FIG. 15, the film transport roller 90 and the rubber roller 80b are disposed at the unclamping position, and the contact prevention roller 86 is lowered to cause the photosensitive web 22 to move. This prevents contact with the rubber roller 80a.

  Further, when the operation of the manufacturing apparatus 20 is finished, the bonded substrate 24a is conveyed in the direction of arrow C under the rotation action of the substrate conveying roller 92, and the web tip cutting mechanism 48a clamps the photosensitive web 22. . Then, in a state where the photosensitive web 22 is clamped while the film transport roller 90 rotates, the web tip cutting mechanism 48a travels in the web width direction and cuts the photosensitive web 22.

  For this reason, as shown in FIG. 16, the photosensitive web 22 passes between the rubber rollers 80a and 80b and is sandwiched by the film transport roller 90, and the contact prevention roller 86 is lowered to bring the photosensitive web 22 into the rubber roller 80a. It is supported away from. The web tip cutting mechanism 48a releases the clamp of the bonded substrate 24a and is disposed at the standby position of the substrate.

  The inter-substrate web cutting mechanism 48 and the web tip cutting mechanism 48a move in the direction of the arrow C in synchronization with the photosensitive web 22 when cutting the photosensitive web 22, but are not limited thereto. It is not a thing. For example, when the web is stopped, the photosensitive web 22 may be cut by running only in the web width direction. Also, a cutting method using a Thomson blade while the web is stopped and a cutting method using a rotary cut while the web is moving are possible.

  Furthermore, in the initial start operation of the manufacturing apparatus 20, as shown in FIG. 17, the contact prevention roller 86 is disposed at the lower position, and the rubber roller 80b is separated from the rubber roller 80a. In this state, the photosensitive web 22 is discharged to a disposal unit (not shown) under the rotating action of the film transport roller 90. At that time, the photosensitive web 22 is cut at regular intervals under the action of the web tip cutting mechanism 48a.

  Then, when the detection mechanism 47 detects the half-cut region 34, a quantitative feed is performed from this detection position. Specifically, when the contact prevention roller 86 is raised, the photosensitive web 22 is conveyed to a position where the half-cut portion 34 reaches the laminating position by the rubber rollers 80a and 80b. Thereby, the cueing process of the photosensitive web 22 is completed.

  In this case, in the first embodiment, the half cut portion 34 of the photosensitive web 22 is directly detected by the detection mechanism 47 in the vicinity of the upstream of the attaching mechanism 46. Note that the distance between the detection mechanism 47 and the half-cut stop point of the rubber rollers 80a and 80b needs to be shorter than the shortest laminate length. This is for feeding back the detected result to the laminating process.

  The detection mechanism 47 performs the following two types of measurement. First, in the first measurement, the glass substrate 24 is clamped by the rubber rollers 80a and 80b, and the substrate feed amount from the start of rotation of the rubber rollers 80a and 80b is measured by an encoder attached to a rubber roller driving motor (not shown). The difference between the number of pulses and the number of set half-cut portion detection timing pulses is compared, and the deviation of the half-cut portion 34 is measured. When the half-cut part 34 is detected earlier than reaching the number of detection timing pulses in the setting, it is determined that the half-cut part 34 is displaced forward from a predetermined position of the glass substrate 24 by the number of pulses corresponding to the earlier part. it can. Conversely, when the detection is slow, it can be determined that the half-cut portion 34 is displaced rearward from a predetermined position of the glass substrate 24.

  On the other hand, in the second measurement, the number of encoder pulses associated with the rubber roller drive motor from the detection of the half-cut region to the detection of the next half-cut region is measured, and the laminate length H is measured. The set number of pulses corresponding to the laminate length H under the normal setting conditions is compared with the actual number of pulses. If the number of pulses is large, the photosensitive web 22 is further extended by the influence of heating or the like by the larger number of pulses. Can be judged. Conversely, when the number of pulses is small, it can be determined that the photosensitive web 22 is shorter than usual.

  Based on the first measurement result, for example, as shown in FIG. 18, it is detected that the front end position of the photosensitive resin layer 28 is shifted forward (advanced) between the pasting ranges P1 and P2 of the glass substrate 24. As a result, the relative position between the glass substrate 24 and the half-cut portion 34 of the photosensitive web 22 is adjusted.

  That is, when it is determined that the position of the half-cut portion 34 detected by the photoelectric sensor 72 is advanced from a predetermined position, as shown in FIG. 10, it is attached to the glass substrate 24 by the substrate transport roller 92 after lamination. By feeding the photosensitive web 22 in the unattached portion, the feed amount is fed by subtracting the deviation from the set amount. As a result, the half-cut portion 34 is adjusted in position and is temporarily disposed at a predetermined position between the rubber rollers 80a and 80b. Thereafter, the glass substrate 24 is fed between the rubber rollers 80a and 80b by regular feed control, and the photosensitive resin layer 28 is placed on the glass substrate 24 in the correct position, that is, in the predetermined pasting ranges P1 and P2 of the glass substrate 24. A photosensitive resin layer 28 is attached.

  On the other hand, if it is determined that the position of the half-cut portion 34 detected by the photoelectric sensor 72 is delayed with respect to the space between the pasting ranges P1 and P2 of the glass substrate 24 as shown in FIG. By feeding the photosensitive web 22 in a portion not attached to the glass substrate 24 by the roller 92, the feed amount is fed by an amount that is larger than the set amount.

  In addition to the method of adjusting the feed amount of the bonded substrate 24a by the substrate transport roller 92, a method of adjusting the stop position of the glass substrate 24 by adjusting the substrate transport mechanism 45 and adjusting the stop position by a shift amount may be adopted. Good.

  Based on the second measurement result, the distance between the half-cut portions detected by the photoelectric sensor 72, that is, the attachment length H of the photosensitive resin layer 28 attached to the glass substrate 24 is measured. When the affixing length H is long, the processing mechanism 36 shortens the length between the half cuts by a long amount, whereas when the affixing length H is short, the half cut portion is lengthened by a short amount. The machining position 34 is changed. Thereby, the pasting length of the photosensitive resin layer 28 can be adjusted to a predetermined length.

  Note that the amount of elongation of the photosensitive web 22 can be changed by adjusting the tension applied to the photosensitive web 22 by the tension dancer 70 constituting the tension control mechanism 66.

  For this reason, the half-cut part 34 of the photosensitive web 22 can be positioned with high accuracy with respect to the attachment position, and the photosensitive resin layer 28 of the photosensitive web 22 can be accurately positioned with respect to a desired part of the glass substrate 24. It becomes possible to paste on. Thereby, the effect that the high-quality photosensitive laminated body 106 can be obtained efficiently with a simple process and structure is acquired.

  FIG. 20 is a schematic configuration diagram of a manufacturing apparatus 120 according to the second embodiment of the present invention. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Similarly, in the third and fourth embodiments described below, detailed description thereof is omitted.

  The manufacturing apparatus 120 includes a detection mechanism 47 a, a cooling mechanism 122 disposed on the downstream side of the inter-substrate web cutting mechanism 48, and a base peeling mechanism 124 disposed on the downstream side of the cooling mechanism 122. The detection mechanism 47a includes photoelectric sensors 72a and 72b. The photoelectric sensors 72a and 72b are spaced apart from each other by a predetermined distance L and are disposed to face the backup rollers 73a and 73b, respectively.

  After the photosensitive web 22 between the bonded substrates 24a is cut through the inter-substrate web cutting mechanism 48, the cooling mechanism 122 supplies cooling air to the bonded substrate 24a to perform a cooling process. Specifically, the cold air temperature is set to 10 ° C., and the air volume is set to 1.0 to 2.0 m / min. Note that the cooling mechanism 122 is not used, and natural cooling may be performed by a photosensitive laminate stocker 132 described later.

  The base peeling mechanism 124 disposed downstream of the cooling mechanism 122 includes a plurality of suction pads 126 for sucking the attachment substrate 24a from below, and the attachment substrate 24a is sucked and held on the suction pads 126. The base film 26 and the remaining portion 30b are peeled off via the robot hand 128. On the upstream, downstream, and both sides of the suction pad 126, static elimination blows (not shown) for injecting ion air from the side surfaces in the four directions are disposed on the entire laminate portion of the attachment substrate 24a. Note that the peeling may be performed with the table vertical, tilted, or turned upside down for dust removal.

  A photosensitive laminate stocker 132 that houses a plurality of photosensitive laminates 106 is provided downstream of the base peeling mechanism 124. The photosensitive laminate 106 from which the base film 26 and the remaining portion 30b are peeled off from the attached substrate 24a by the base peeling mechanism 124 is sucked and taken out by the suction pad 136 provided on the hand part 134a of the robot 134, and is photosensitive. The laminate stocker 132 is accommodated.

  A dust removal fan unit (or duct unit) 137 is attached to the substrate stocker 71 and the photosensitive laminate stocker 132 on three side surfaces other than the inlet and outlet ports. The fan unit 137 blows out the static elimination clean air into the substrate stocker 71 and the photosensitive laminate stocker 132.

  In addition to the laminating control unit 102 and the substrate heating control unit 104, a base peeling control unit 138 is connected to the laminating process control unit 100. The base peeling control unit 138 controls the operation of peeling the base film 26 from the sticking substrate 24a supplied from the sticking mechanism 46 and discharging the photosensitive laminate 106 to the downstream process, and the sticking substrate. 24a and information on the photosensitive laminate 106 are controlled.

  In the second embodiment configured as described above, in the detection mechanism 47a, first, the upstream photoelectric sensor 72a detects the half-cut portion 34 of the photosensitive web 22, and then the downstream photoelectric sensor 72b The half cut part 34 is detected. At this time, the distance L between the backup rollers 73 a and 73 b substantially corresponds to the length of the photosensitive resin layer 28 to be attached to the glass substrate 24.

  For this reason, the actual attachment length of the photosensitive resin layer 28 is accurately calculated from the time difference at which the half-cut portion 34 is detected by the photoelectric sensors 72a and 72b. Therefore, the feed amount of the photosensitive web 22 is adjusted so that the position at which the photosensitive resin layer 28 is attached to the center of the glass substrate 24 is set from the measured value.

  Thereby, in 2nd Embodiment, the length H of the photosensitive resin layer 28 affixed on the glass substrate 24 between the half cut site | parts 34 of the photosensitive web 22, is detected correctly, and this photosensitive resin layer 28 can be attached to the center of the glass substrate 24 (see FIG. 21).

  Here, when the length H1 of the photosensitive resin layer 28 detected by the detection mechanism 47a is longer than the normal length H, both ends of the photosensitive resin layer 28 are attached as shown in FIG. It is attached to the central portion of the glass substrate 24 so as to be distributed from the attachment length L outward by equal distances.

  On the other hand, as shown in FIG. 23, when the length H2 of the photosensitive resin layer 28 is shorter than the regular length H, both ends of the photosensitive resin layer 28 are inward of the affixed length L. Affixed to the center of the glass substrate 24 so as to be distributed at equal distances. At that time, the target deviation of the pasting position is about ½ times that in the case where the target cannot be sorted.

  Further, in the second embodiment, a half cut portion 34 is formed on the photosensitive web 22 fed from the web feed mechanism 32, the protective film 30 is peeled off leaving the remaining portion 30b, and then laminated on the glass substrate 24. The photosensitive resin layer 28 is transferred, and the base film 26 and the remaining portion 30b are peeled off via the base peeling mechanism 124 to manufacture the photosensitive laminate 106. Thereby, the effect that automation of the whole manufacturing process of the photosensitive laminated body 106 can be performed easily is acquired.

  FIG. 24 is a schematic configuration diagram of a manufacturing apparatus 140 according to the third embodiment of the present invention.

  The manufacturing apparatus 140 does not normally use the inter-substrate web cutting mechanism 48 except for work such as web cutting at the time of trouble stop and separation for discharging defective products, and downstream of the web tip cutting mechanism 48a. A cooling mechanism 122 and a base automatic peeling mechanism 142 are provided. The automatic base peeling mechanism 142 continuously peels the long base film 26 to which the respective glass substrates 24 are pasted at predetermined intervals, and is separated from the pre-peeling portion 144 and a relatively small diameter peeler. A roller 146, a winding shaft 148, and an automatic pasting machine 150 are provided. The take-up shaft 148 preferably applies torque control during driving to apply tension to the base film 26, while providing a tension detector (not shown) on the peeling roller 146, for example, to perform tension feedback control. .

  As shown in FIGS. 25 and 26, the pre-peeling portion 144 includes nip rollers 152 and 154 and a peeling bar 156. The nip rollers 152 and 154 can be moved back and forth in the conveyance direction of the glass substrate 24, and the upper rollers 152a and 154a can be raised and lowered to sandwich the glass substrate 24 with the lower rollers 152b and 154b. The peeling bar 156 can be moved up and down between the glass substrates 24. In place of the upper rollers 152a and 154a, a pressing bar or a pressing pin may be used.

  In addition, the film surface is reheated to about 30 ° C. to 120 ° C. immediately before the peeling roller 146 or immediately before that, and the peeling of the photosensitive resin layer (coloring material layer) 28 at the time of peeling is prevented. Can be obtained. Here, for example, the cushion layer 27 may be heated within a predetermined temperature range (described later) below the glass transition temperature (Tg). As a heating method in this case, the peeling roller 146 may be configured as a heating roller such as a hot water roller, or a bar heater or an IR heater may be provided.

  A measuring instrument 158 that measures the area position of the photosensitive resin layer 28 actually attached to the glass substrate 24 is disposed downstream of the automatic base peeling mechanism 142. The measuring device 158 includes a camera 160 such as a CCD, for example, and as shown in FIG. 27, four units of the above-mentioned four corners K1 to K4 of the glass substrate 24 to which the photosensitive resin layer 28 is attached are photographed. A camera 160 is provided. Moreover, it may replace with four corners K1-K4, and may be arrange | positioned at least 2 units | sets by the vertical and horizontal direction.

  Note that the measuring instrument 158 employs a configuration in which image processing is performed by the camera 160, but an end face position may be detected by a color sensor or a laser sensor, or an LED sensor, a photo array, a line sensor, or the like may be combined. At that time, it is desirable to arrange at least two units on each end face and detect the linearity of the end faces.

  In addition, by energizing a surface inspection device (not shown), unevenness due to the photosensitive web 22 itself, unevenness in the density of the laminate due to equipment, wrinkles, streaks, and surface conditions such as dust and foreign matter While detecting a defect and giving an alarm, it can utilize for the management of NG discharge | emission and a post process.

  In the third embodiment configured as described above, 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, while the nip rollers 152 and 154 sandwich the rear end and the front end of the adjacent glass substrate 24, the nip roller 152 moves in the direction of arrow C at the same speed as the glass substrate 24, The moving speed of the nip roller 154 in the direction of arrow C is reduced.

  Accordingly, as shown in FIG. 26, the photosensitive web 22 between the glass substrates 24 is bent between the nip rollers 152 and 154, and the peeling bar 156 is raised, so that the protective film 30 is moved to the rear end and the front end of the adjacent glass substrate 24. Can be peeled off.

  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 at a trouble stop or after separation at the time of defective product separation, the tip of the base film 26 of the pasted substrate 24a that has been newly laminated and the base film that is wound around the winding shaft 148 26 is automatically pasted via the automatic pasting machine 150.

  The glass substrate 24 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 four cameras 160 with the glass substrate 24 positioned and fixed. The pasting positions a to d are calculated by performing image processing.

  In the inspection station, the glass substrate 24 is transported without stopping, and the position of the end face is detected by a camera or scan in the width direction, while the position of the glass substrate 24 is detected by a timing sensor or the like in the traveling direction. You may perform the measurement by acquisition or sensor detection.

  Thus, in the third embodiment, the photosensitive film 22 between the bonded substrates 24a is not cut after lamination, and the base film 26 is removed from the bonded substrate 24a under the rotating action of the winding shaft 148. It can be wound up continuously. Further, the processing operation of the peeled base film 26 is easy.

  Thereby, in the third embodiment, the same effects as those of the second embodiment are obtained, such as the entire manufacturing operation of the photosensitive laminate 106 being automatically and efficiently performed, and the configuration is further simplified. To do.

  FIG. 28 is a schematic configuration diagram of a manufacturing apparatus 180 according to the fourth embodiment of the present invention.

  As shown in FIG. 29, the photosensitive web 22 used in the manufacturing apparatus 180 includes a base film 26, a cushion layer (thermoplastic resin layer) 27, an intermediate layer (oxygen barrier film) 29, a photosensitive resin layer 28, and a protective film. A film 30 is laminated.

  The base film 26 is formed of polyethylene terephthalate (PET), the cushion layer 27 is formed of ethylene and vinyl oxide copolymer, the intermediate layer 29 is formed of polyvinyl alcohol, and the photosensitive resin layer 28 is alkali-soluble. It is formed of a colored photosensitive resin composition containing a binder, a monomer, a photopolymerization initiator, and a colorant, and the protective film 30 is formed of polypropylene.

  The manufacturing apparatus 20 includes, on the downstream side of the inter-substrate web cutting mechanism 48, a cooling mechanism 122 that cools the adhesive substrate 24a on which the photosensitive web 22 from which the protective film 30 has been peeled off and the glass substrate 24 are attached, Of the bonded substrate 24a, the resin layer, for example, the cushion layer 27 is adsorbed by a heating mechanism 182 that heats the resin layer to a predetermined temperature range (described later) below the glass transition temperature (Tg) and a plurality of adsorption pads 184. And a base peeling mechanism 186 that peels the base film 26 from the held pasted substrate 24a to obtain the photosensitive laminate 106.

  The cooling mechanism 122 supplies cooling air to the pasting substrate 24a to perform cooling processing. Specifically, the cooling air temperature is set to 10 ° C. and the wind speed is set to 0.5 to 2.0 m / min. . The heating mechanism 182 includes a heating roller 188 disposed on the base film 26 side of the bonded substrate 24a, and a receiving roller 190 disposed on the glass substrate 24 side so as to face the heating roller 188.

  The heating roller 188 performs internal or external heating by, for example, an electromagnetic induction heating method, and directly contacts the base film 26 to heat the cushion layer 27 from the base film 26 side. In place of the electromagnetic induction heating method, a sheathed heater heating method, a warm water (liquid) heating method, or the like can be adopted. The heating roller 188 may be a rubber roller, a metal roller, a cloth winding roller, a resin roller, or the like, and a plurality of heating rollers 188 may be arranged in the arrow C direction.

  The receiving roller 190 does not need to be heated, and may be a cooling roller that circulates a cooling fluid as necessary.

  The cushion layer 27 is heated by the heating roller 188 within a predetermined temperature range equal to or lower than the glass transition temperature. The glass transition temperature of the cushion layer 27 is obtained from a value at which tan δ (loss factor) is detected by viscoelasticity measurement and tan δ is maximized.

  In the laminated film, the characteristics of temperature and tan δ were detected using a viscoelasticity measuring device manufactured by Toyo Baldwin Co., Ltd., and the results shown in FIG. 30 were obtained. Thereby, the glass transition temperature of the cushion layer 27 was 37.8 degreeC.

  As shown in FIG. 31, the base peeling mechanism 186 includes a frame member 192, and the frame member 192 has an upper guide that extends in the direction of arrow D perpendicular to the conveyance direction (arrow C direction) of the attached substrate 24 a. Rails 194a and 194b extend in parallel with a predetermined distance from each other. Below the upper guide rails 194a, 194b, lower guide rails 195a, 195b, which are shorter than these, similarly extend in the direction of arrow D and are provided in parallel with each other. The upper guide rails 194a and 194b support self-propelled movable members 198a and 198b that can advance and retract along the direction of arrow D via motors 196a and 196b.

  As shown in FIGS. 31 and 32, the movable members 198a and 198b extend in the vertical direction (arrow E direction), and guide rails 200a and 200b extending in the vertical direction are provided on the side surfaces facing each other. Provided. Lift rails 202a and 202b are supported on the guide rails 200a and 200b, and the lift rails 202a and 202b can be lifted and lowered via motors 204a and 204b.

  Rotation drive sources 206a and 206b are mounted on the elevators 202a and 202b in the horizontal direction, and chucks 208a and 208b are fixed to the rotation shafts (not shown) of the rotation drive sources 206a and 206b. The chucks 208a and 208b are configured to be rotatable, and at the base film peeling position of the adhesive substrate 24a, both sides of the base film 26 projecting outward from both ends in the transport direction of the glass substrate 24 constituting the adhesive substrate 24a. The position can be adjusted to a position where the part can be freely gripped.

  As shown in FIG. 31, slide bases 210a and 210b are supported by the lower guide rails 195a and 195b, and both ends of the copying roller 212 are supported by the slide bases 210a and 210b so as to be movable up and down. The slide bases 210a and 210b are configured to be movable back and forth between predetermined positions in the arrow D direction integrally with the movable members 198a and 198b.

  In the fourth embodiment configured as described above, each bonded substrate 24a separated by the inter-substrate web cutting mechanism 48 is transported to the cooling mechanism 122 as shown in FIG. Forcibly, for example, after being cooled to room temperature (approximately 20 ° C.), it is conveyed to the heating mechanism 182. In the heating mechanism 182, the bonded substrate 24 a is sandwiched between the heating roller 188 and the receiving roller 190, and heat is directly transferred from the heating roller 188 to the base film 26 of the bonded substrate 24 a.

  Thereby, after the cushion layer 27 is heated to a predetermined temperature from the base film 26, the attached substrate 24 a is sent to the base peeling mechanism 186. In the base peeling mechanism 186, the glass substrate 24 side of the bonded substrate 24 a is held under the suction action of the suction pad 184, while the chucks 208 a and 208 b are base films that protrude inward from both ends of the glass substrate 24 in the transport direction. 26 on one end side in the direction of arrow D (see FIG. 33).

  Therefore, the movable members 198a and 198b move to the affixing substrate 24a under the action of the motors 196a and 196b, and the chucks 208a and 208b open and close to hold both ends of the base film 26 in the transport direction. Further, the chucks 208a and 208b rotate under the action of the rotational drive sources 206a and 206b, while the elevators 202a and 202b and the movable members 198a and 198b are driven and controlled in a predetermined direction.

  Therefore, as shown in FIGS. 32 and 33, the chucks 208a and 208b move along a predetermined peeling locus, and the base film 26 held by the chucks 208a and 208b is separated from the cushion layer 27 and pasted. It peels from the attachment board | substrate 24a. At that time, the copying roller 212 moves to a predetermined position in the direction of the arrow D integrally with the movable members 198a and 198b, and peels the base film 26 smoothly and satisfactorily. When the base film 26 is peeled from the pasting substrate 24a, the photosensitive laminate 106 is obtained.

  In this case, in the fourth embodiment, the cushion layer 27 of the bonded substrate 24a that is forcibly cooled via the cooling mechanism 122 is once heated from the base film 26 side to near the glass transition temperature under the action of the heating mechanism 182. After that, the base film 26 is peeled off via the base peeling mechanism 186.

  That is, in the attaching mechanism 46, the photosensitive web 22 is thermocompression bonded to the glass substrate 24 in a state where a predetermined tension is applied, and residual stress is likely to be generated in the cushion layer 27. Further, since a forced cooling process is performed on the bonded substrate 24 a by the cooling mechanism 122, residual stress is easily generated in the cushion layer 27. Accordingly, if the base film 26 is peeled off from the pasting substrate 24a in this state, the cushion layer 27 is likely to be cracked or damaged by the residual stress of the cushion layer 27. For this reason, in the cushion layer 27, a defective portion such as irregularities is generated, causing a deterioration in quality.

  Therefore, in the fourth embodiment, before the base film 26 is peeled off, the residual stress of the cushion layer 27 is reduced by heating from the base film 26 side to a temperature near the glass transition temperature of the cushion layer 27. ing.

  Here, the surface temperature of the base film 26 was changed variously, and an experiment was performed to detect the presence or absence of peeling failure when the base film 26 was peeled off. The result is shown in FIG. Thereby, the surface temperature of the base film 26 is set within a temperature range of 32 ° C. to 38 ° C. corresponding to a predetermined temperature range equal to or lower than the glass transition temperature (37.8 ° C.) of the cushion layer 27. Good peeling treatment was performed, and a high-quality photosensitive laminate 106 was obtained.

  Moreover, the heating mechanism 182 heats the bonded substrate 24a from the base film 26 side. Therefore, since the peeling part of the base film 26 and the cushion layer 27 is heated to a desired temperature more quickly and accurately than when heating from the glass substrate 24 side, a highly accurate peeling process at the peeling part is performed. There is an advantage that it becomes feasible.

  Further, the base peeling mechanism 186 is separated from the heating mechanism 182 by a predetermined interval. For this reason, the bonded substrate 24 a that has been once heated to relieve the residual stress is cooled while being transferred to the base peeling mechanism 186.

  By the way, the copying roller 212 constituting the base peeling mechanism 186 may be heated from a heating mechanism (not shown) and brought into contact with the base film 26, whereby the base film 26 may be peeled off from the cushion layer 27 while being heated. A plurality of copying rollers 212 may be provided.

  In the fourth embodiment, the base peeling mechanism 186 is configured to peel the base film 26 in the direction of arrow D intersecting the transport direction (arrow C direction) of the attached substrate 24a. The peeling direction of the film 26 may be set in the direction of arrow C parallel to the conveying direction of the attached substrate 24a.

  Further, a preheating mechanism (not shown) may be installed on the upstream side of the heating mechanism 182 to assist heating of the bonded substrate 24a. As the preheating mechanism, for example, an infrared power heater such as a coil, carbon, or halogen, a ceramic IR heater, various contact-type heating rollers, or the like is used.

  Furthermore, in the fourth embodiment, the manufacturing apparatus 20 according to the first embodiment is basically adopted, but the present invention is not limited to this, and the manufacturing apparatus according to the second and third embodiments. You may apply to 120,140.

  FIG. 35 is a schematic perspective explanatory view of the base peeling mechanism 220 constituting the manufacturing apparatus according to the fifth embodiment of the present invention. Note that the same components as those of the base peeling mechanism 186 constituting the manufacturing apparatus 180 according to the fourth embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Similarly, in the sixth embodiment described below, detailed description thereof is omitted.

  The base peeling mechanism 220 includes a tension applying structure 222 that applies a tension to the base film 26 in the attaching direction (arrow C direction) to the base film 26 when the base film 26 is peeled from the attaching substrate 24a. .

  The tension applying structure 222 includes movable chuck members 224a, 226a, 228a, and 230a that can grip the front end portion 26a of the base film 26 that protrudes outward from the front end side in the transport direction of the attached substrate 24a, and the transport of the pasted substrate 24a. And a movable chuck member 224b, 226b, 228b, and 230b that is capable of gripping the rear end portion 26b of the base film 26 protruding rearward in the direction.

  The chuck members 224a and 224b are opposed to each other in the direction of arrow C, and the other chuck members 226a, 226b, 228a, 228b and 230a and 230b are arranged to face each other in the direction of arrow C. The chuck members 224a to 230a and 224b to 230b are configured to be openable and closable and to be movable back and forth with respect to the base film 26, respectively.

  In the fifth embodiment configured as described above, when the pasting substrate 24 a is disposed at the base peeling position, the chuck members 224 a to 230 a configuring the tension applying structure 222 grip the tip end portion 26 a of the base film 26. At the same time, the chuck members 224 b to 230 b grip the rear end portion 26 b of the base film 26. In this state, the chuck members 224a to 230a and the chuck members 224b to 230b are subjected to torque control in a direction away from each other, whereby a predetermined tension is applied to the base film 26 in the arrow C direction.

  Accordingly, the chucks 208a and 208b grip the front end portion 26a and the rear end portion 26b of the base film 26 and move in the direction of arrow D1 along a predetermined peeling locus. At that time, a predetermined tension is applied to the base film 26 in the direction of the arrow C, and the base film 26 can be peeled off from the glass substrate 24 smoothly and reliably.

  Further, when the copying roller 212 moves in the direction of the arrow D1 and comes close to the chuck members 224a and 224b, the chuck members 224a and 224b release the gripping action of the front end portion 26a and the rear end portion 26b of the base film 26. , Move in directions away from each other (arrow direction). For this reason, the chuck members 224 a and 224 b do not interfere with the copying roller 212. As the copying roller 212 moves in the direction of arrow D1, the chuck members 226a and 226b are detached from the base film 26, and then the chuck members 228a and 228b and the chuck members 230a and 230b are sequentially separated from the base film 26. Then, the peeling operation of the base film 26 is completed.

  FIG. 36 is a schematic perspective explanatory view of the base peeling mechanism 230 constituting the manufacturing apparatus according to the sixth embodiment of the present invention.

  The base peeling mechanism 230 includes a tension applying structure 232 that applies a tension to the base film 26 in a direction in which the base film 26 is attached to the attaching substrate 24a when the base film 26 is released from the attaching substrate 24a.

  The tension applying structure 232 includes a front end chuck 234 capable of gripping the front end portion 26a of the base film 26 protruding toward the front end side in the transport direction of the attached substrate 24a, and the base film 26 protruding rearward in the transport direction of the pasted substrate 24a. And a rear end chuck 236 capable of gripping the rear end portion 26b. The front end chuck 234 and the rear end chuck 236 are configured to be wide in the direction of arrow D, and can respectively hold the front end portion 26a and the rear end portion 26b of the base film 26 over substantially the entire width direction.

  The tip chuck 234 is mounted on the rotational drive sources 206a and 206b, and the other structure is the same as that of the base peeling mechanism 186 of the fourth embodiment. In this case, the moving direction of the tip chuck 234 is set in the arrow C direction orthogonal to the moving direction (arrow D direction) of the chucks 208a and 208b.

  In the sixth embodiment configured as described above, when the attached substrate 24a is transported to the base peeling position, the distal end portion 26a of the base film 26 projecting toward the distal end side of the attached substrate 24a becomes the distal end chuck 234. To be gripped. On the other hand, the rear end portion 26b of the base film 26 protruding to the rear end side of the pasting substrate 24a is held by the rear end chuck 236.

  Next, the rear end chuck 236 or the rear end chuck 236 and the front end chuck 234 are subjected to torque control, and tension is applied along the arrow C direction to the base film 26 sandwiched therebetween. In this state, when the tip chuck 234 moves along a predetermined peeling locus, the base film 26 to which a predetermined tension is applied is smoothly and reliably peeled from the glass substrate 24.

  FIG. 37 is a schematic explanatory diagram of a base automatic peeling mechanism 250 constituting a manufacturing apparatus according to the seventh embodiment of the present invention. Note that the same components as those of the base automatic peeling mechanism 142 constituting the manufacturing apparatus 140 according to the third embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The automatic base peeling mechanism 250 includes a peeling bar (peeling guide member) 252 that guides the base film 26 along the outer peripheral portion of the peeling roller 146 while moving between the pasting substrates 24a. The peeling bar 252 can advance and retreat in the vertical direction (arrow E direction) under the action of the cylinder 254. A ball screw 258 connected to a motor 256 is engaged with the cylinder 254 and can advance and retreat in the direction of arrow C. The peeling roller 146 is desirably heated by a heat source (not shown).

  In the seventh embodiment configured as described above, as shown in FIG. 38, when the peeling bar 252 is disposed between the pasting substrates 24a, the peeling bar 252 protrudes upward under the action of the cylinder 254. The base film 26 is pressed against the outer peripheral surface of the peeling roller 146 from the remaining portion 30b side. Further, the ball screw 258 rotates under the action of the motor 256, the cylinder 254 moves in the direction of arrow C, and the peeling bar 252 is pressed against the peeling roller 246 via the cylinder 254 (see FIG. 39).

  Thereby, the peeling bar 252 guides the remaining portion 30 b along the outer peripheral surface of the peeling roller 246. Therefore, as shown in FIG. 40, when the peeling bar 252 moves to a predetermined position on the outer peripheral portion of the peeling roller 146, the remaining portion 30b is reliably peeled from the rear end portion of the front attached substrate 24a. Then, it is wound up integrally with the base film 26. For this reason, when the base film 26 is peeled from the bonded substrate 24a, the remaining portion 30b does not remain on the bonded substrate 24a, and a good automatic peeling process can be performed.

  The peeling bar 252 has a spherical tip, but is not limited thereto. For example, as shown in FIG. 41, a peeling bar 260 having a tapered tip end portion 260a having a tapered surface on the peeling roller 146 side may be employed.

  FIG. 42 is an explanatory front view of the attaching mechanism 270 constituting the manufacturing apparatus according to the eighth embodiment of the present invention.

  The pasting mechanism 270 includes rubber rollers 80a and 80b and backup rollers 272a and 272b, and the outer periphery of the backup rollers 272a and 272b is set in a crown shape. Note that at least one of the backup rollers 272a and 272b or at least one of the rubber rollers 80a and 80b may be configured as a crown roller.

  The crown shape is composed of a sine curve, a quadratic curve, or a quartic curve. For example, as shown in FIG. 43, the roll surface length L = 1000 mm to 3000 mm, the roll diameter φ = 200 mm to 300 mm, the crown amount d (= 2d1) = 0.1 mm to 3.0 mm, and the laminate linear pressure is 100 N / Cm to 200 N / cm.

  FIG. 44 is a schematic perspective explanatory view of a processing mechanism 290 constituting a manufacturing apparatus according to the ninth embodiment of the present invention, and FIG. 45 is a schematic configuration diagram of the processing mechanism 290.

  The processing mechanism 290 includes a heating mechanism 292 that heats the half-cut portion 34 of the photosensitive web 22 to a predetermined temperature (described later), and a cutter mechanism 294 that performs half-cut along the half-cut portion 34 heated to the predetermined temperature. With.

  The cutter mechanism 294 includes a linear guide 296 extending in an arrow B direction orthogonal to the conveyance direction (arrow A direction) of the photosensitive web 22, and a slide base 298 is supported on the linear guide 296. A motor 300 is built in the slide table 298, and a pinion 302 is pivotally mounted on a rotation drive shaft 300 a of the motor 300. The linear guide 296 is provided with a rack 304 that extends in the arrow B direction and meshes with the pinion 302, and the slide base 298 can advance and retreat in the arrow B direction under the action of the motor 300.

  The slide base 298 is provided with a rotating shaft 306 that protrudes on the opposite side to the pinion 302, and a rotating round blade (cutter) 308 that can rotate integrally with the rotating shaft 306 is fixed to the rotating shaft 306. . At a position facing the rotary round blade 308, a cut receiving base 310 is disposed with the photosensitive web 22 interposed therebetween.

  The cut cradle 310 is composed of two metal plates and extends in the direction of arrow B. A concave portion 312 is formed on the upper surface of the cut receiving base 310 over the range of movement of the rotary round blade 308 in the arrow B direction, and the resin receiving portion 314 is accommodated in the concave portion 312.

  The heating mechanism 292 includes a sheet-type heater 316 embedded in the cut receiving base 310, specifically, sandwiched between two metal plates. The cut cradle 310 functions as a heating member that contacts the photosensitive web 22 and directly heats the half-cut portion 34. Here, the sheet heater 316 may be installed between the recess 312 and the receiving portion 314.

  Instead of the rotating round blade 308, a fixed round blade 320 fixed to a fixed shaft 318 extending from the slide base 298 may be used. The angular position of the fixed round blade 320 can be adjusted by a predetermined angle with respect to the fixed shaft 318.

  The half-cut portion 34 needs to cut at least the protective film 30. In practice, the cutting depth of the rotary round blade 308 (or the fixed round blade 320) is set in order to cut the protective film 30 reliably. The The half-cut portion 34 is formed by, for example, a cutting method using ultrasonic waves, a knife blade, a belt-like push cutting blade (Thomson blade), which will be described later, instead of the rotating round blade 308 (or the fixed round blade 320). A method may be adopted. The push cutting blade includes an oblique push cutting structure in addition to a vertical push cutting structure.

  In the ninth embodiment configured as described above, the sheet type heater 316 constituting the heating mechanism 292 is energized, and the cut receiving base 310 provided with the sheet type heater 316 is heated to a desired temperature. . For this reason, the photosensitive web 22 sent in the direction of arrow A is directly heated in contact with the cut receiving base 310 that moves in synchronization with the photosensitive web 22, and the half-cut portion 34 corresponds to the rotating round blade 308. Then, it is half-cut through the cutter mechanism 294 while being heated to a predetermined temperature set in advance. The half cut may be performed with the photosensitive web 22 stopped.

  Specifically, when the pinion 302 rotates under the driving action of the motor 300 provided on the slide base 298, the slide base 298 is supported by the linear guide 296 under the meshing action of the pinion 302 and the rack 304. Move in the direction of arrow B. Therefore, the rotating round blade 308 rotates while moving in the arrow B direction in a state where the half cut portion 34 of the photosensitive web 22 is cut to a desired depth. As a result, a half-cut portion 34 is formed in the photosensitive web 22 by cutting the protective film 30 to a desired depth.

  In this case, the half cut portion 34 of the photosensitive web 22 is heated by the heating mechanism 292, and the half cut portion 34 is half cut by the cutter mechanism 294. At that time, by setting the heating temperature of the photosensitive web 22 in advance for each of the rotating round blade 308 and the fixed round blade 320, it is possible to satisfactorily prevent the generation of cut dust and delamination.

  In the ninth embodiment, the recess 312 is formed in the cut receiving base 310 and the receiving portion 314 is accommodated in the recess 312. A resin receiving film may be directly provided on the upper surface of the table. Further, instead of the sheet type heater 316, a sheathed heater or a tube type heater may be used, and a heating box is provided by accommodating the cutter mechanism 294 and the half cut portion 34, and hot air is supplied into the heating box. Also good. Furthermore, in order to heat the photosensitive web 22 before half-cutting, a heating plate, a bar heater, or a heating box may be provided on the upstream side of the cutter mechanism 294.
