  For example, a liquid crystal panel substrate, a printed wiring substrate, and a PDP panel substrate are configured as a laminate substrate in which a photosensitive laminate film (photosensitive web) having a photosensitive resin layer is attached to the substrate surface. In this photosensitive laminate film, a thermoplastic resin layer (hereinafter also referred to as a cushion layer), a photosensitive material layer (resist layer), and a protective film are usually laminated sequentially on a base film (flexible plastic support layer). Has been.

  In view of this, a pasting apparatus used for pasting this type of photosensitive laminate film usually transports substrates such as a glass substrate and a resin substrate spaced apart from each other by a predetermined distance, and is pasted on the substrate. In accordance with the range of the photosensitive resin layer, a method is employed in which the protective film is peeled off from the photosensitive laminate film.

  For this reason, it is necessary to cut | disconnect a protective film in a predetermined position previously, before a photosensitive laminated body film is conveyed to a sticking apparatus. At this time, at least the protective film is cut, that is, half-cut treatment is performed on the photosensitive laminate film, leaving at least part of the lamination direction.

  As an apparatus for performing this kind of half cut, for example, a film cutting apparatus disclosed in Patent Document 1 is known.

  And the 1st half cut site | part which comprises the peeling direction rear end part of a 2nd resin layer is formed by moving a rotatable cutter relatively along the width direction of a laminated body film. Here, the rotatable cutter refers to a cutter that rotates the laminated film while being cut in half when moving along the width direction of the laminated film. In addition to a blade), a polygonal cutter (rotating polygonal blade) and the like are included.

  On the other hand, the second half-cut portion constituting the front end portion in the peeling direction of the second resin layer is formed by relatively moving the cutter fixed so as not to rotate along the width direction of the laminated film. Here, the non-rotatable cutter is a cutter that half-cuts the laminated film while being held in the same posture when moving along the width direction of the laminated film. In addition to these cutters (hereinafter also referred to as fixed round blades), polygonal cutters (fixed polygon blades), knife blades, push cutting blades (fixed blades) and the like are included.

  Further, the half-cut device includes a moving mechanism that can move along the width direction of the laminated film, and the moving mechanism includes a rotatable cutter and a non-rotatable cutter corresponding to the half-cut interval.

It is preferable to include a second moving mechanism that can move along the second moving mechanism.

  Furthermore, the half-cut device includes a moving mechanism that can move along the width direction of the laminated film, and the moving mechanism selectively functions as a rotatable cutter and a non-rotatable cutter. A cutter with a fixing mechanism is preferably attached.

  Moreover, it is preferable that a laminated body film is a photosensitive laminated body film whose 1st resin layer is a photosensitive resin layer.

  In the present invention, since the first half-cut portion constituting the rear end portion in the peeling direction of the second resin layer is formed by the rotatable cutter, it is possible to satisfactorily prevent the generation of cut waste in the first half-cut portion. can do. At that time, the first resin layer is easily peeled off at the first half-cut portion, but the first half-cut portion is the rear end portion in the peeling direction of the second resin layer, and the second resin layer is peeled off. In this case, unnecessary peeling of the first resin layer is not caused.

  On the other hand, since the second half-cut portion constituting the tip portion of the second resin layer in the peeling direction is formed by the cutter fixed so as not to rotate, the first resin layer is peeled off at the second half-cut portion. Can be reliably prevented.

  Therefore, when the second resin layer is peeled, unnecessary peeling of the first resin layer is not caused at the front end portion in the peeling direction, and the quality can be improved. For this reason, while ensuring cut quality, adhesion of the cut waste to a cutter is prevented, and improvement of work efficiency, such as cleaning work, is easily aimed at.

  The operation of the manufacturing apparatus 20 configured as described above will be described below in relation to the half-cut method according to the first embodiment.

  First, as shown in FIG. 1, the photosensitive web 22 is fed out from a photosensitive web roll 22 a attached to the web feed mechanism 32, and the photosensitive web 22 is sent to a half-cut device 36.

  In the half-cut device 36, as shown in FIGS. 4 to 6, the moving mechanism 52 moves in the direction of the arrow B in synchronization with the photosensitive web 22 while the photosensitive web 22 is fed in the direction of the arrow A. Half-cut processing is performed on the photosensitive web 22. Half-cut processing may be performed with the photosensitive web 22 stopped.

  Specifically, the moving mechanism 52 is provided with a first cutter mechanism 56 and a second cutter mechanism 58, and the rotating round blade 66 of the first cutter mechanism 56 and the fixed round blade of the second cutter mechanism 58. 72 moves in the direction of arrow B together.

  At that time, the rotary round blade 66 rotates (follows) while moving in the arrow B direction in a state where the blade edge 66a is cut to a desired depth in the first half-cut portion 34a of the photosensitive web 22. For this reason, a first half-cut portion 34a cut from the protective film 30 to a desired depth is formed in the photosensitive web 22 (see FIG. 2).

  On the other hand, the fixed round blade 72 moves in the direction of the arrow B while being fixed in a non-rotatable state while being cut into the second half-cut portion 34b of the photosensitive web 22 to a desired depth. Accordingly, the photosensitive web 22 is cut to a desired depth from the protective film 30 and is separated from the first half-cut portion 34a by a predetermined distance to form a second half-cut portion 34b (see FIG. 2). .

  In this case, in the first embodiment, since the first half-cut portion 34a is formed by the rotatable rotary round blade 66, the first half-cut portion 34a is effectively prevented from generating cut waste. can do.

  At that time, as shown in FIG. 7, the photosensitive resin layer 29 is easily peeled off at the first half-cut portion 34 a. However, the first half-cut portion 34a constitutes the rear end portion of the protective film 30 in the peeling direction. As will be described later, when the protective film 30 is peeled off, the photosensitive resin layer 29 is unnecessarily peeled off. Is never evoked.

  Further, the peeled portion of the first half-cut portion 34a exists on the leading end side of the remaining portion 30b of the protective film 30, and this remaining portion 30b is a portion that is not used as a transfer portion and is discarded later. is there. Therefore, by forming the first half-cut portion 34a with the rotary round blade 66, it is possible to effectively reduce the cutter waste and to prevent the image quality from being lowered.

  On the other hand, the second half-cut portion 34 b is formed by the fixed round blade 72. For this reason, it is possible to prevent the photosensitive resin layer 29 from peeling off at the second half-cut portion 34b. The second half-cut portion 34b constitutes the leading end of the protective film 30 in the peeling direction, and the photosensitive resin layer 29 is satisfactorily prevented from peeling off, so that only the protective film 30 is peeled off reliably and smoothly. It becomes possible.

  Thereby, it is possible to obtain an effect that the photosensitive web 22 can be half cut with high quality and generation of cut waste can be prevented as much as possible with a simple process and configuration. In particular, with the rotating round blade 66, it is possible to easily improve work efficiency such as cleaning work because the attachment of cut waste is prevented.

  Therefore, a conventional example in which the first half-cut part 34a and the second half-cut part 34b are formed by a fixed round blade, and the first half-cut part 34a is formed by a rotating round blade 66, and the second half-cut part 34 is fixed by a fixed round blade. When the processing state by this invention formed with the blade 72 was compared, the result shown in FIG. 8 was obtained.

  That is, in the conventional example, since the fixed round blade is used for each of the first half-cut portion 34a and the second half-cut portion 34b, the generation of cut waste becomes remarkable. For this reason, there existed a problem that the removal process of the cut waste adhering to each fixed round blade became complicated, and cut quality fell.

  On the other hand, in this invention, while the generation | occurrence | production of cut waste was reduced favorably, the effect that peeling of the photosensitive resin layer 29 in a transfer part was prevented favorably was acquired.

  By the way, as described above, the half-cut photosensitive web 22 is conveyed to the label adhering mechanism 40 as shown in FIG. 1, and a predetermined application portion of the protective film 30 is arranged on the cradle 86. Is done. In the label adhering mechanism 40, a predetermined number of adhesive labels 38 are adsorbed and held by the adsorbing pads 84b to 84e, 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, the base film 26 of the photosensitive web 22 is adsorbed and held on the suction drum 92, 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 93 and wound around the protective film take-up portion 94. In addition, it is preferable to spray static elimination air on a peeling site | part.

  At this time, the photosensitive web 22 is firmly held by the suction drum 92, 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 the tension control mechanism 96, and further the detection mechanism 47 detects the photoelectric. The sensor 102 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 138a based on the detection information of the half-cut portion 34. At that time, the contact prevention roller 136 waits upward, and the rubber roller 130b is disposed below.

Is temporarily disposed between the rubber rollers 130a and 130b.

  In this state, by raising the backup roller 132b and the rubber roller 130b through the roller clamp part 134, the glass substrate 24 is sandwiched between the rubber rollers 130a and 130b with a predetermined pressing pressure. Further, the photosensitive resin layer 29 is transferred (laminated) to the glass substrate 24 by heating and melting under the rotating action of the rubber roller 130a.

  Here, as lamination conditions, the speed is 1.0 m / min to 10.0 m / min, the temperature of the rubber rollers 130 a and 130 b is 100 ° C. to 140 ° C., the rubber hardness of the rubber rollers 130 a and 130 b is 40 degrees to 90 degrees, The pressing pressure (linear pressure) of the rubber rollers 130a and 130b is 50 N / cm to 400 N / cm.

  The substrate 24 a having the photosensitive web 22 attached to the glass substrate 24 is quantitatively conveyed in the direction of arrow C, cooled through the cooling mechanism 140, and then transferred to the base peeling mechanism 142. In this base peeling mechanism 142, the base film 26 and the remaining portion 30 b are peeled off via the robot hand 146 while the substrate 24 a is sucked and held on the suction pad 144, and the multilayer substrate 150 is obtained.

  At that time, neutralizing clean air is sprayed from the side surfaces in the four directions to the entire laminate portion of the substrate 24a upstream, downstream, and both sides of the suction pad 144. The laminate substrate 150 is held by the hand unit 152a of the robot 152 and is stored in a predetermined number in the photosensitive laminate stocker 156.
