Abstract

A rubber roller (110a) is pressed against a photosensitive web (22) and rotated to thermally compress the photosensitive web (22) against a glass substrate (24), thereby producing a bonded substrate (24a). If it is judged that the rubber roller (110a) will be stopped against rotation for a predetermined period of time, then the rubber roller (110a) is rotated a predetermined angle. Thus, the trailing end of the bonded substrate (24a) that is closest to the rubber roller (110a) becomes spaced a desired distance from. the rubber roller (110a), and hence is prevented from being adversely affected by radiant heat from the rubber roller (110a). ® KIPO & WIPO 2009

Description

Extension web attachment method {METHOD OF APPLYING ELONGATE WEB}

The present invention relates to a method of continuously attaching an extension web to a substrate by thermocompression.

For example, the board | substrate for liquid crystal panels, the board | substrate for printed circuits, and the board | substrate for PDP panels have the photosensitive sheet (extension web) containing the photosensitive material (photosensitive resin) layer adhering to the board | substrate surface. The photosensitive sheet includes a photosensitive material layer and a protective film sequentially stacked on a flexible plastic support.

An attachment apparatus for attaching such a photosensitive sheet usually supplies substrates such as glass substrates, resin substrates, and the like at spaced intervals, and peels the protective film from the photosensitive sheet body, and then attaches the photosensitive material layer to the substrate.

The attachment device usually includes a pair of laminate rolls that are heated to a predetermined temperature by induction heating or the like. The photosensitive sheet body and the substrate are gripped by a laminate roll and thermocompression-bonded to each other.

The photosensitive sheet is likely to cause various defects. A laminate substrate body made of a substrate with a poor photosensitive sheet cannot be easily processed by the regeneration treatment because of the peeling of the photosensitive material layer in the post treatment and the pretreatment of the substrate. Since the regeneration process is low in efficiency and high in cost, it is also difficult to reuse the substrate. Therefore, it is common to discard such a laminated substrate body in which a bad photosensitive sheet body is affixed to each board | substrate normally.

Japanese Laid-Open Patent Publication No. 2003-62906 discloses a film laminating method. According to the film lamination method, before the film is laminated to the substrate, judging whether the film contains a defect or not is monitored. If it is determined that the film contains a defect, then the region of the film containing the defect is discarded, and only the non-defective region of the film is attached to the substrate.

Undesired disposal of the normal substrate can be avoided because non-defective areas of the film that are not peeled off from the film roll are attached to each substrate.

Usually, when the laminating process is stopped, the rear end of the laminate substrate body which was finally laminated is disposed in the vicinity of the laminate roll. Therefore, the rear end of the laminate substrate body is likely to be heated by radiant heat from the laminate roll. When the lamination roll is stopped continuously for a predetermined time, the photosensitive resin layer of the laminate substrate main body is subjected to heat effect and thus the quality is easily degraded, resulting in a failure of the laminate substrate main body. Therefore, whenever it is stopped in the laminating process to replace the film roll with a new one, a defective laminate substrate body is generated. Therefore, conventional film lamination methods are not economical.

In addition, while the lamination treatment is stopped, the film located upstream of the laminate roll is also susceptible to heat effects, and the quality is degraded. At least one laminated film and one film prior to lamination, which are positioned upstream and downstream of the laminate roll, respectively, are defective. In addition, loss of a large number of film pieces occurs, which makes the conventional film lamination process uneconomical.

It is an object of the present invention to provide a method of attaching an elongated web to a substrate that can efficiently and economically produce high quality laminates without being affected by heat rollers held stationary through a simple process.

According to the present invention, there is provided a method of attaching continuous webs of extension length to each substrate by thermocompression bonding. According to this method, by pressing the heating roller disposed at the attachment position against the extension web and rotating the heating roller, a part of the extension web is thermocompressed onto the substrate until the heating roller reaches the attachment stop angle position, thereby stacking the extension web. The sieve is prepared on a substrate.

If it is judged that the thermocompression of the elongated web is stopped for a predetermined time, the rear end of the laminate closest to the heating roller is moved from the heating roller by moving the heating roller from the attachment stop angle position to a predetermined angle. Spaced apart.

The attachment stop angular position refers to the angular position at which the rotation of the heating roller is stopped before the portion of the extended web is thermocompressed to each substrate when the laminate is sequentially manufactured by thermally compressing a portion of the extended web to the substrate.

Preferably, the extending web comprises a laminated multilayer web having at least a first layer and a second layer, wherein the method partially cuts the extending web leaving part of the transverse web of the laminated multilayer web, thereby reducing the length of the substrate. And forming partial cutting sites in the extending web at respective spaced intervals accordingly. In addition, if it is determined that the thermocompression of the extension web is stopped for a predetermined time, the rotation of the heating roller is angularly moved until at least a part of the extension web between adjacent regions of the partial cutting portion is disposed on the outer circumferential surface of the heating roller. And then stopping the rotation of the heating roller.

Preferably, the extending web comprises a laminated multi-layer web having at least a first layer and a second layer, wherein the method partially cuts the extending web leaving part of the transverse web of the laminated multi-layer web, thereby reducing the length of the substrate. And forming partial cutting sites in the elongate web at spaced intervals, respectively. In addition, if it is determined that the thermocompression of the elongated web is stopped for a predetermined time, a stationary partial cut portion in the extended web is formed at a position spaced a predetermined distance from one of the partial cut portions. The heating roller then includes a step of stopping the rotation of the heating roller after each movement until at least a portion between one of the partial cutting portions and the stationary partial cutting portion is disposed on an outer circumferential surface of the heating roller.

Preferably, the predetermined distance between one of the partial cutting portions and the stationary partial cutting portion is smaller than the distance between adjacent portions of the partial cutting portions and longer than the length of the elongated web thermally affected by the heating roller.

More preferably, if it is determined that the thermocompression of the elongating web is stopped for a predetermined time, the method then spaces a portion of the elongated web which is in contact with or in proximity to the heat roller and is thermally affected by the heat roller. To maintain the portion of the elongated web.

Once the extension web is thermocompressed once again, the method further includes transferring a heat affected portion of the extension web from the attachment position that is determined to be thermally affected by the heating roller in contact with or in proximity to the heating roller. . In addition, after the heat-affected portion of the elongated web is transferred from the attachment position, the heating roller is rotated to thermocompress other portions of the elongated web to the substrate other than the heat-affected portion of the elongated web.

According to the present invention, if it is determined that the thermocompression of the extension web is stopped for a predetermined time, the heating roller is further rotated to a predetermined angle, so that the rear end of the laminate closest to the heating roller is the desired distance from the heating roller. Space apart.

Therefore, the rear end of the laminate is not exposed to radiant heat from the heating roller for a long time. Therefore, for example, the quality of the photosensitive resin layer functioning as an extended web is maintained well. The laminate is well prevented from the heat effect by the stop of the heating roller in a simple process, and the laminate is produced with high quality and efficiently and economically.

These and other objects, features, and advantages of the present invention will become more apparent from the following description when taken in conjunction with the accompanying drawings, in which preferred embodiments of the present invention are shown as illustrative examples.

The photosensitive resin layer 29 is formed from the coloring photosensitive resin composition containing an alkali-soluble binder, a monomer, a photoinitiator, and a coloring agent. The protective film 30 is formed of polyethylene, polypropylene, or the like.

As shown in FIG. 1, the manufacturing apparatus 20 receives the photosensitive web roll 22a in the form of a roll-shaped photosensitive web 22 and delivers the photosensitive web 22 from the photosensitive web roll 22a. A partial cutting mechanism 36 for forming a transverse cuttable partial cutting portion 34 in the web feeding mechanism 32 and the protective film 30 of the photosensitive web 22 fed out from the photosensitive web roll 22a; And a label adhering mechanism 40 for adhering the adhesive label 38 (see FIG. 3) having the non-adhesive portion 38a to the protective film 30. The two partial cutting mechanisms 36 may be provided at intervals spaced apart in the direction indicated by the arrow A, and may simultaneously form each of the two partial cutting portions 34.

Downstream of the label adhesive mechanism 40, a reservoir mechanism 42 for changing the transfer mode of the photosensitive web 22 from the tact transfer mode (for example, the interrupted transfer mode) to the continuous transfer mode, and the photosensitive web ( 22 is a peeling mechanism 44 that peels the protective film 30 to a predetermined length, and a heating mechanism that heats the glass substrate 24 to a predetermined temperature and transfers the heated glass substrate 24 to the attachment position ( 45 and the attachment mechanism 46 which attaches the photosensitive resin layer 29 exposed by peeling of the said protective film 30 to the said glass substrate 24 are arrange | positioned. A workpiece configured by bonding the photosensitive web 22 to the glass substrate 24 by the attachment mechanism 46 will be referred to as "attachment substrate 24a" hereinafter.

The partial cutting tool 36 includes a slide base 52 that is retractable in a direction orthogonal to the direction in which the photosensitive web 22 is conveyed (arrow A direction). A rotating circular blade (cutter) 54 is fixed to the slide base 52, and a photosensitive web 22 is fitted below the rotating circular blade 54 so that the cutter bearing base 56 is installed.

As shown in FIG. 2, the partial cutting portion 34 needs to be formed at least via the protective film 30. In practice, the rotating circular blade 54 is designed to be cut up to the photosensitive resin layer 29 and the intermediate layer 28 in order to surely cut the protective film 30. The partial cutting portion 34 may be formed by a cutting process using a fixed circular blade or ultrasonic energy rather than the rotating circular blade 54, or a cutting process using a knife blade, a band-like pressing blade (described later), or the like. . In addition, the pressing blade may be pressed in the direction perpendicular or inclined to the protective film 30.

The partial cutting portion 34 is provided to set the spaced spacing between two adjacent glass substrates 24. Specifically, such spacing is indicated by the spaced apart spacing between two adjacent glass substrates 24 + the distance in which the partial cutting portion 34 is spaced inwardly from each edge of the glass substrate 24-frame dimension. For example, such partial cutting portions 34 are formed in the protective film 30 at positions spaced 10 mm inward from each edge of the glass substrate 24. The portion of the protective film 30 is sandwiched between the partial cutting portions 34 serving as masks when the photosensitive resin layer 29 is bonded as a frame to the glass substrate 24 in the attachment mechanism 46 described later. .

As shown in FIGS. 2 and 3, the short portion of the protective film 30 extending between two adjacent partial cutting portions 34 has a length L1 corresponding to the distance between the partial cutting portions 34. On the other hand, the long portion of the protective film 30 extending between two adjacent partial cutting portions 34 is the substrate length along the front peeling portion 30aa or the back peeling portion 30ab, that is, the length of the glass substrate 24. A partial cutting portion 34 has a distance spaced inwardly from each edge of the glass substrate 24 minus a distance L2 corresponding to the dimensions of the frame.

As shown in FIG. 3, each adhesive label 38 has a rectangular band shape and is formed of the same resin material as the protective film 30. Each adhesive label 38 has a non-adhesive portion 38a (microadhesive layer) located at the non-adhesive center portion, and both ends in the longitudinal direction of the non-adhesive portion 38a, that is, at both ends in the longitudinal direction of the adhesive label 38, respectively. The first adhesive part 38b and the second adhesive part 38c are disposed. The first adhesive part 38b and the second adhesive part 38c are joined to the front peeling part 30aa and the rear peeling part 30ab, respectively.

As shown in FIG. 1, the labeling mechanism 40 has adsorption pads 58a to 58e capable of attaching up to five adhesive labels 38 at spaced intervals. The support base 59, which is vertically movable to support the photosensitive web 22 from below, allows the adhesive label 38 to be attached to the photosensitive web 22 by the adsorption pads 58a to 58e. It is placed in the position to be attached.

The protective film 30 peeled off from the photosensitive web 22 at the acute peeling angle via the wound peeling roller 64 is wound up by the protective film winding shaft 66 except the remaining part 30b. The protective film winding shaft 66 is connected to the torque motor 68, for example, in order to impart a predetermined tension to the protective film 30.

Downstream of the peeling mechanism 44, a tension control mechanism 76 is disposed to impart tension to the photosensitive web 22. The tension control mechanism 76 includes a cylinder 78, which is capable of adjusting the tension of the photosensitive web 22 in which the tension pickup roller 80 is kept in rolling contact by the oscillating displacement of the tension pickup roller 80. The tension control mechanism 76 can be used only when needed or can be removed.

The detection mechanism 47 includes a photoelectric sensor 82 such as a laser sensor or a photo sensor, the photoelectric sensor 82 having a wedge-shaped groove of the partial cutting portion 34 or a thickness difference of the protective film 30. The change in the photosensitive web 22 due to the step generated by or a combination thereof is directly detected. The detected signal from the photoelectric sensor 82 is used as a boundary position signal indicating a boundary position on the protective film 30. The photoelectric sensor 82 is disposed opposite the backup roller 83. Alternatively, a non-contact displacement meter or an image inspection means such as a CCD camera or the like may be used instead of the photoelectric sensor 82.

The positional data of the partial cutting portion 34 detected by the detection mechanism 47 can be converted into statistical processing and graph data in real time. When the position data detected by the detection mechanism 47 shows a large gap or inclination, the manufacturing apparatus 20 can generate an alarm.

The manufacturing apparatus 20 may employ another system for generating a boundary position signal. For example, with such other systems, the partial cutting portion 34 is not directly detected, but the mark is applied to the photosensitive web 22. For example, a hole or a groove may be formed in the vicinity of the partial cutting mechanism 36 corresponding to the partial cutting portion 34, or the photosensitive web 22 may be slit by laser light or aqua jet, or It can be marked by an inkjet or a printer. A mark is detected on the photosensitive web 22, and the detected signal is used as a boundary position signal.

The heating mechanism 45 further includes a plurality of heating furnaces 90 disposed downstream of the receiver 88.

The heating mechanism 45 constantly monitors the temperature of the glass substrate 24. When the heating mechanism 45 detects an abnormal temperature, the heating mechanism 45 generates a stop or alarm of the feed roller 86, sends information indicating the abnormal operation, and discharges the abnormal glass substrate 24. It can be used for quality control or production control. The transfer mechanism 84 has an air lifting plate (not shown) for lifting the glass substrate 24, and can be transferred in the direction indicated by the arrow C.

Upstream of the heating mechanism 45 is a substrate storage frame 100 in which a plurality of glass substrates 24 are accommodated. The substrate storage frame 100 includes a vibration damping fan unit 102 (or a duct unit) disposed at each of three sides of the substrate storage frame 100 in addition to the input and output slot portions. The fan unit 102 blows out vibration damping clean air in the substrate storage frame 100.

A cooling mechanism 120 is disposed downstream of the inter-substrate web cutting mechanism 48, and a base peeling mechanism 122 is disposed downstream of the cooling mechanism 120. The cooling mechanism 120 performs cooling by supplying cold air to the attachment substrate 24a after the attachment substrate 24a and the photosensitive web 22 are cut | disconnected by the inter-substrate web cutting mechanism 48. FIG. Specifically, the cooling mechanism 120 supplies cold air whose air volume is 1.0 degreeC-2.0 m / min with a cold air temperature of 10 degreeC. However, the cooling mechanism 120 is not used or the attachment substrate 24a can naturally cool in the photosensitive laminated storage frame 136 described later.

The base peeling mechanism 122 disposed downstream of the cooling mechanism 120 has a plurality of adsorption pads 124 that adsorb from the bottom of the attachment substrate 24a. While the attachment substrate 24a is adsorbed by the suction pad 124, the base film 26 and the remaining portion 30b are peeled off from the attachment substrate 24a by the robot hand 126. Upstream, downstream, and both sides of the adsorption pad 124 are provided with vibration suppression blowers (not shown) for injecting vibration suppression clean air from the side surfaces in four directions of the laminate portion of the attachment substrate 24a. The base film 26 and the remaining portion 30b may be peeled from the attachment substrate 24a, but the table supporting the attachment substrate 24a may be oriented vertically, inclined or vice versa to promote dust removal. .

To control. In addition, the base peel controller 146 controls the information on the attachment substrate 24a and the photosensitive laminate 130.

The manufacturing apparatus 20 is separated into the first clean room 152a and the second clean room 152b by the separating wall 150. The first clean room 152a is accommodated in the tension control mechanism 76 from the web delivery mechanism 32. The second clean room 152b houses subsequent components along the detection mechanism 47. The first clean room 152a and the second clean room 152b are in contact with each other through the through part 154.

 The operation of the manufacturing apparatus 20 for performing the bonding according to the first embodiment of the present invention will be described below.

As shown in FIG. 1, the photosensitive web 22 is sent out from the photosensitive web roll 22a attached to the web delivery mechanism 32, and this photosensitive web 22 is conveyed to the partial cutting mechanism 36. As shown in FIG. .

In the partial cutting mechanism 36, the slide base 52 moves across the photosensitive web 22 in the vertical direction of the photosensitive web 22 (indicated by image A). The rotating circular blade 54 cuts to the desired depth at the partially cut portion 34 of the photosensitive web 22 and rotates as it moves across the photosensitive web 22. Therefore, slits that are cut to the desired depth from the protective film 30 are formed in the partially cut portion 34 of the photosensitive web 22 (see FIG. 2).

As shown in FIG. 1, the partially cut photosensitive web 22 is stopped once after conveying the distance corresponding to the dimension of the remaining portion 30b of the protective film 30 in the direction indicated by the arrow A, The next circular cut portion 34 is formed by the rotating circular blade 54. As shown in FIG. 2, the front peeling portion 30aa and the rear peeling portion 30ab are provided by sandwiching the remaining portion 30b therebetween in the photosensitive web 22.

At that time, the photosensitive web 22 is conveyed to the label adhesive mechanism 40, and the predetermined bonding site | part of the protective film 30 is arrange | positioned on the support base 59. FIG. In the label adhesive mechanism 40, a predetermined number of adhesive labels 38 are adsorbed and supported on the adsorption pads 58a to 58e to cross the remaining portion 30b of the protective film 30 of each adhesive label 38 to the front. It is integrally bonded to the peeling part 30aa and the back peeling part 30ab (refer FIG. 3).

For example, the photosensitive web 22 to which the five adhesive labels 38 are adhered is prevented from the tension fluctuation provided to the photosensitive web 22 by the reservoir mechanism 42, as shown in FIG. 1. It is conveyed to the peeling mechanism 44 continuously.

In the peeling mechanism 44, the photosensitive web 22 is sandwiched between the suction drum 62 and the peeling roller 64 so that the base film 26 of the photosensitive web 22 is adsorbed to the suction drum 62. . When the suction drum 62 is rotated, torque is applied to the protective film 30 by the torque motor 68.

Thus, the protective film 30 is peeled off from the photosensitive web 22 leaving the remaining portion 30b. The protective film 30 is peeled off at an acute peeling angle by the peeling roller 64 and wound around the protective film winding shaft 66. It is preferable to apply damping air to the site | part from which the protective film 30 peeled.

The protective film 30 is peeled from the base film 26 by the peeling mechanism 44 leaving the remaining portion 30b, and then the photosensitive web 22 is tension-controlled by the tension control mechanism 76. At that time, the partial cutting part 34 of the photosensitive web 22 is detected by the photoelectric sensor 82 with the detection mechanism 47.

In the first embodiment, the lamination treatment is performed by the continuous operation shown in FIG.

The photosensitive web 22 starts operation based on the detection information of the partial cutting part 34, and is conveyed a predetermined distance toward the attachment mechanism 46 under the rotation of the film feed roller 118a. Thereafter, the photosensitive web 22 is conveyed by the substrate transfer roller 118b to the attachment mechanism 46 by a predetermined distance, and the attachment substrate 24a of the partial cutting portion 34 is supported on the basis of the detected information. At that time, the contact prevention roller 116 waits upward and the rubber roller 110b is arrange | positioned downward.

The heating temperature in the heating furnace 90 in the heating mechanism 45 is set by the lamination temperature in the attachment mechanism 46. The robot 104 supports the glass substrate 24 accommodated in the substrate storage frame 100 and supports the glass substrate 24 to the receiver 88. In the receiver 88, the glass substrate 24 is conveyed sequentially from the receiver 88 to the heating furnace 90 by the transfer roller 86 of the transfer mechanism 84 in the tact transfer mode.

In the heating furnace 90 downstream of the heating mechanism 45 in the direction indicated by the arrow C, the glass substrate 24 is stopped at the predetermined stop position accurately. The glass substrate 24 is arranged at the bonding site | part of the photosensitive resin layer 29 of the photosensitive web 22 (shown in FIG. 5), and is arrange | positioned between rubber rollers 110a and 110b once.

At that time, the roller clamp unit 114 lifts up the backup roller 112b and the rubber roller 110b so that the glass substrate 24 is sandwiched between the rubber rollers 110a and 110b under a predetermined press pressure. The rubber roller 110a is rotated, and the photosensitive resin layer 29 laminated on the glass substrate 24 is transferred by heat melting, for example.

The photosensitive resin layer 29 has a speed of 1.0 m / min to 10.0 m / min, a temperature of the rubber rollers 110a and 110b of 80 ° C to 140 ° C, and a rubber hardness of the rubber rollers 110a and 110b of 40 to 90. In addition, the press pressure (linear pressure) of the said rubber rollers 110a and 110b is laminated | stacked on the glass substrate 24 under the state which the photosensitive resin layer 29 of 50N / cm-400N / cm conveyed.

As shown in FIG. 6, when the lamination of one unit length of the photosensitive web 22 to the glass substrate 24 having the rubber rollers 110a and 110b is finished, the rotation of the rubber roller 110a is stopped. The angle position at which the rubber roller 110a is stopped in rotation is referred to as the attachment stop angle position.

The attachment substrate 24a on which the photosensitive web 22 is laminated on the glass substrate 24 is clamped by the substrate transfer roller 118b. The rubber roller 110b is withdrawn from the rubber roller 110a, and the photosensitive web 22 is unclamped.

The lamination of one unit length of the photosensitive web 22 is now terminated (time t1 in FIG. 4). During the time T1 to T4 until the next lamination cycle starts, the glass substrate 24 heated to a predetermined temperature by the heating mechanism 45 is conveyed and disposed between the rubber rollers 110a and 110b. The photosensitive web 22 is held in contact with the rubber roller 110a and microscopically conveyed.

Specifically, as shown in Fig. 4, when a predetermined time T2 has elapsed from the end time T1 of the preceding lamination process, the rubber roller 110a starts low speed rotation. The photosensitive web 22 held in contact with the rubber roller 110a is conveyed in the direction indicated by the arrow C by a predetermined distance until the time T3. At this time, the substrate feed roller 118b is rotated at low speed in synchronization with the rubber roller 110a, and microscopically conveys the attached substrate 24a in the direction indicated by the arrow C. FIG.

From time T4 the next laminate cycle begins. When the time T5 elapses, the next attaching substrate 24a is manufactured. Between the time T6 and the time T7, the photosensitive web 22 is microscopically conveyed under the rotation of the rubber roller 110a.

By the way, after a predetermined number of substrates 24a are manufactured, the lamination process is stopped for a certain time, for example, 90 seconds or more. For example, the lamination process is stopped when the photosensitive web roll 22a is exchanged for a new photosensitive web roll 22a in the web delivery mechanism 32. While the laminating treatment is stopped, while the rear end of the immediately attached laminated substrate 24a is disposed in the vicinity of the rubber roller 110a, it is likely to be adversely affected by radiant heat from the rubber roller 110a. The photosensitive web 22 partially cut to a predetermined length long corresponding to the length of the next glass substrate 24 upstream of the rubber roller 110a is also susceptible to radiation heat from the rubber roller 110a.

According to the first embodiment, if the remaining number of glass substrates 24 is known and the lamination processing stop command is known in advance, any length of the photosensitive web 22 discarded by changing the partial cutting position to be formed is reduced. Let's do it. Specifically, the photosensitive web 22 is continuously conveyed without stopping, and as shown in FIG. 7, than the next partial cutting portion 34b of the partial cutting portion 34a previously formed by the partial cutting mechanism 36. The stationary partial cutting portion 34c is formed in the preceding position.

The partial cutting portion 34a and the stationary partial cutting portion 34c are spaced apart from the predetermined distance L3. This fixed distance L3 is smaller than the predetermined interval L2 between the partial cutting portions 34a and 34b and longer than the length of the photosensitive web 22 subjected to heat influence from the rubber roller 110a which is a heating roller. For example, distance L3 = 1/2 x distance L2.

Then, the photosensitive with the partial cutting part 34 immediately formed in the front of the area | region 22b extended between the partial cutting part 34a and the stationary partial cutting part 34c from the rear end side of the laminated substrate 24a initially laminated. The web 22 is gradually bonded to the glass substrate 24 to be laminated (see time Tn1 to Tn4 in FIG. 4).

When the area 22b reaches the position immediately before the attachment mechanism 46, as shown in FIG. 8, the rubber roller 110b is spaced apart from the rubber roller 110a, and the glass substrate 24 is moved to the rubber roller 110a. , The rubber roller 110a is rotated while not being conveyed between 110b) (times Tn5 to Tn6 in FIG. 4). The rubber roller 110a is rotated in a predetermined angle range, and the substrate transfer roller 118b is rotated in synchronization with the rotation of the rubber roller 110a. Therefore, the attachment substrate 24a manufactured immediately before the area 22b is moved by a predetermined distance in the direction indicated by the arrow C. FIG.

Then, the substantially center portion of the area 22b is disposed on the outer circumferential surface of the rubber roller 110a, and when the distance h between the rear end of the attachment substrate 24a and the rubber roller 110a becomes a predetermined distance, the rubber Rotation of the roller 110a and the substrate transfer roller 118b is stopped (time Tn6 in FIG. 4).

Therefore, the rear end of the attachment substrate 24a is not exposed to the radiant heat from the rubber roller 110a through a long time. In particular, the photosensitive resin layer 29 maintains excellent quality. According to a simple process, it is prevented from being thermally affected by the time when the rubber roller 110a is stopped. The attachment substrate 24a is prevented from becoming defective, and a high quality attachment substrate 24a can be manufactured efficiently and economically.

According to the first embodiment, when the laminating process is stopped for a predetermined time or more, the partial cutting is performed by the constant distance L3 shorter than the distance L2 between the partial cutting portions 34a and 34b formed on the photosensitive web 22. The part cut part 34c for a stop set in which the part 34c was divided from the part cut part 34a is formed. When the region 22b extending between the partial cutting portion 34a and the stationary partial cutting portion 34c is disposed in contact with the outer circumferential surface of the rubber roller 110a, the rotation of the rubber roller 110a is stopped.

Therefore, the range in which the photosensitive web 22 is affected by heat from the rubber roller 110a is approximately 0.5 unit length (constant) of the laminated 1 unit length (corresponding to the predetermined distance L2) of the photosensitive web 22. Corresponding to the distance L3). Thus, the portion of the photosensitive web 22 that can be defective by radiant heat is limited within the laminated one unit length of the photosensitive web 22, and effectively prevents the calculation of the photosensitive web 22 from being lowered.

When the manufacturing apparatus 20 performs lamination again, the photosensitive web (the rubber roller 110a is rotated and the area 22b of the photosensitive web 22 is judged to be thermally affected by the rubber roller 110a) The length corresponding to 0.5 unit length of 22) is conveyed in the direction indicated by arrow C. After the substantially defective area 22b is conveyed downstream of the bonding site, the lamination of the next unit length of the photosensitive web 22 is started on the next glass substrate 24.

For example, the roughly defective portion 22b of the photosensitive web 22, which is determined to be in contact with or in proximity to be thermally affected by the rubber roller 110a, is not laminated onto the glass substrate 24. As shown in FIG. As a result, the bad adherent substrate 24a is prevented from being manufactured.

As shown in FIG. 1, the substrate 24a on which the photosensitive web 22 is bonded to the glass substrate 24 is conveyed a predetermined distance in the direction indicated by the arrow C, and cooled by the cooling mechanism 120. And the base peeling mechanism 122. While the attachment substrate 24a is adsorbed by the adsorption pad 124 in the base peeling mechanism 122, the base film 26 and the remaining portion 30b are peeled off by the robot hand 126, and the photosensitive laminate 130 is removed. ).

At this time, the damping clean air is injected from the air blowers disposed upstream, downstream and on both sides of the suction pad 124 on the side surfaces of the laminated portions of the attachment substrate 24a in four directions. The photosensitive laminate 130 is supported by the hand portion 132a of the robot 132 and disposed in the photosensitive laminate storage frame 136. The operation is repeated until a predetermined number of photosensitive stacks 130 are stored in photosensitive stack storage frame 136.

An extension web attachment method according to a second embodiment of the present invention will be described below with reference to FIG. 9. In addition, the extension web attachment method according to the second embodiment can be performed using the manufacturing apparatus 20 shown in FIG.

According to this second embodiment, when it is judged that the laminating process is stopped continuously for a predetermined time or more, the rear end of the attached substrate 24a closest to the rubber roller 110a is spaced apart by a predetermined distance in the direction indicated by the arrow C. Let's do it. In addition, an anti-contact roller 116 is disposed downstream to bring the photosensitive web 22 that is not in contact with the rubber roller 110a.

Specifically, the suction drum 62 is fixed to rotation by a brake (not shown), and the cylinder 78 of the tension control mechanism 80 is synchronized with the contact preventing roller 116 to move the tension control mechanism 80. Driven to move. As shown in FIG. 9, when the photosensitive web 22 is spaced apart from the rubber roller 110a by the contact preventing roller 116, the photosensitive web 22 extends through a predetermined length of path.

Since the photosensitive web 22 is spaced apart from the rubber roller 110a by the contact preventing roller 116, the range affected by the heat of the photosensitive web 22 (area 22b) by the radiant heat from the rubber roller 110a. Is reduced. As a result, the length of the area 22b discarded as the defective web portion is shortened.

An extension web attachment method according to a third embodiment of the present invention will be described below with reference to FIG. In addition, the extension web attachment method according to the third embodiment can be performed using the manufacturing apparatus 20 shown in FIG.

According to the third embodiment, when the laminating stop command is input, the conveyance of the photosensitive web 22 is not stopped, and the rotation of the rubber roller 110a is continued. Rotation of the rubber roller 110a when the approximately center portion of the photosensitive web 22 region 22c lying between the partial cutting portion 34 and the partial cutting portion 34a is disposed on the outer circumferential surface of the rubber roller 110a. Is stopped.

The range in which the photosensitive web 22 is thermally affected by the rubber roller 110a is reduced from the length of the conventional laminated two units to the length of the laminated one unit of the photosensitive web 22. As a result, the calculation of the photosensitive web 22 is effectively prevented from being lowered. By controlling the rotation of the rubber roller 110a to be easily controlled, the substantially center portion of the predetermined area 22c provided between the partial cutting portions 34 and 34a can be simply controlled, thereby simplifying the control process. Through this, it is possible to efficiently and economically obtain a high quality attachment substrate 24a.

In the first to third embodiments, the method of attaching the extended web has been described as being performed by the manufacturing apparatus 20 for thermally transferring the photosensitive resin layer 29 of the single extended photosensitive web 22 to the glass substrate 24. . However, the present invention is not limited only to this application. In addition, the method according to the present invention can be performed by a manufacturing apparatus that thermally transfers two or more photosensitive resin layers of a single parallel extending photosensitive web onto the same glass substrate.

While certain preferred embodiments of the invention have been shown and described in detail, it is understood that various changes and modifications may be made without departing from the scope of the invention as defined in the appended claims.
