Description

  The present invention provides a photosensitive laminate by feeding a substrate and a long photosensitive web provided with a photosensitive material layer on a support between a pair of pressure rollers, and affixing the photosensitive material layer to the substrate. The present invention relates to a manufacturing apparatus and a manufacturing method for a photosensitive laminate.

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

  A manufacturing apparatus used for adhering this type of photosensitive sheet body is usually attached to the substrate while a substrate such as a glass substrate or a resin substrate is transported between the lamination rollers at a predetermined interval. A method is adopted in which a photosensitive sheet body from which a protective film corresponding to the range of the photosensitive resin layer is peeled is conveyed between the lamination rollers.

  For example, in the manufacturing apparatus disclosed in Patent Document 1, as shown in FIG. 11, a laminate film (photosensitive sheet body) 1a fed out from a film roll 1 is wound around guide rollers 2a and 2b to be horizontal. It extends along the film transport surface. A rotary encoder 3 that outputs a number of pulse signals corresponding to the feed amount of the laminated film 1a is attached to the guide roller 2b.

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

  The half-cutter device 5 includes a pair of disc cutters 5a and 5b that are separated from each other by a predetermined distance in the transport direction of the laminated film 1a. As shown in FIG. 12, the disc cutters 5a and 5b move along the film width direction of the laminate film 1a, so that a peeled portion A and a remaining portion in the cover film (not shown) of the laminate film 1a are obtained. The two boundary portions 14a and 14b between B and B are cut together with the photosensitive resin layer (not shown) with the support film remaining.

  The cover film peeling apparatus 6 strongly presses the adhesive tape 7a fed from the adhesive tape roll 7 to the peeling portion A of the cover film between the pressing rollers 8a and 8b, and then winds it by the take-up roll 9. Thereby, the peeling part A of a cover film is peeled from the photosensitive resin layer, and is wound up by the winding roll 9 with the adhesive tape 7a.

  Downstream of the suction roller 4, a pair of laminations in which the peeled portion A of the laminated film 1 a from which the cover film has been peeled are stacked and pressure-bonded on the upper surfaces of the plurality of substrates 11 that are transported at a predetermined interval by the substrate transport device 10. Rollers 12a and 12b are disposed. A support film take-up roll 13 is disposed downstream of the lamination rollers 12a and 12b. A support film (not shown) attached to the photosensitive resin layer is wound around the support film winding roll 13 together with the remaining portion B of the cover film with the photosensitive resin layer remaining on the substrate 11.

  By the way, in order to attach the peeling portion A of the laminate film 1a from which the cover film has been peeled off to a desired range of the substrate 11, for example, a boundary portion 14a between the peeling portion A and the remaining portion B of the cover film is provided. It is necessary to feed the laminated film 1a between the lamination rollers 12a and 12b with high accuracy so that the laminated film 1a is set at a predetermined position at a distance K from the front end of the substrate 11.

  In this case, in the conventional manufacturing apparatus, the number of pulses of the pulse signal output from the rotary encoder 3 is counted, and a predetermined pulse until the boundary portion 14a formed by the half cutter device 5 reaches the lamination rollers 12a and 12b. When the number reaches, the pressure bonding of the peeled portion A of the laminate film 1a to the substrate 11 is started.

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

  However, since the laminate film 1a is formed by forming a photosensitive resin layer on a flexible support film and is transported in a tensioned state, the laminate film 1a is extended during transportation. There is a possibility that the position of the boundary portion 14a attached to the substrate 11 is shifted. In particular, since the lamination rollers 12a and 12b are attached in a state where the laminate film 1a and the substrate 11 are heated, the extension of the laminate film 1a in the vicinity of the lamination rollers 12a and 12b is large.

  Therefore, if the pasting process on the substrate 11 is continuously performed, the deviation of the pasting position is accumulated and exceeds the allowable range. Therefore, after a predetermined number of pasting processes, the amount of deviation of the position where the laminate film 1a is attached to the substrate 11 is measured, and the positions where the boundary portions 14a and 14b are formed by the half cutter device 5 to correct the deviation. Need to be corrected. In this case, since the number of photosensitive laminates that can be processed continuously is limited, the production efficiency is significantly reduced.

  The present invention can detect the position of a processing site formed on a long photosensitive web with high accuracy with a simple configuration and can efficiently produce a high-quality photosensitive laminate. It aims at providing the manufacturing apparatus and manufacturing method of a conductive laminate.

The present invention feeds a long photosensitive web in which a photosensitive material layer and a protective film are sequentially laminated on a support, and a processing site corresponding to a boundary position between a peeled portion and a remaining portion of the protective film, A pair of pressure bonding formed on the portion from the protective film to the photosensitive material layer, after peeling off the peeled portion of the protective film, and then heating the long photosensitive web together with the substrate supplied at a predetermined interval.

The control unit 130 is connected. The half-cut control unit 130 outputs a pulse count start signal to the rotary encoder 51 in response to the processing of the half-cut portions 34a and 34b, and the long photosensitive web 22 to the shutter control unit 124. The prescribed number of pulses corresponding to the prescribed feed amount until the half-cut portion 34 a reaches the reference position set in the imaging unit 47 is output to the shutter control unit 124. The shutter control unit 124 compares the count value of the number of pulses supplied from the rotary encoder 51 with the specified number of pulses supplied from the half-cut control unit 130, and when they match, the shutter signal is sent to the CCD camera 72. Is output.

This is the condition.

  Next, operation | movement of the manufacturing apparatus 20 comprised as mentioned above is demonstrated in relation to the manufacturing method which concerns on this invention.

  First, the long photosensitive web 22 is fed from the photosensitive web roll 23 attached to the web feed mechanism 32. The long photosensitive web 22 is conveyed to the processing mechanism 36.

  In the processing mechanism 36, the round blades 52a and 52b move in the width direction of the long photosensitive web 22, and the long photosensitive web 22 is moved from the protective film 30 to the photosensitive resin layer 28 to the flexible base film. Cut to 26 to form half-cut portions 34a and 34b separated by the width M of the remaining portion B of the protective film 30 (see FIG. 2). As a result, the long photosensitive web 22 is provided with a front peeling portion A and a rear peeling portion A across the remaining portion B (see FIG. 2).

  The width M of the remaining portion B is set on the basis of the distance between the glass substrates 24 supplied between the rubber rollers 80a and 80b of the attaching mechanism 46 on the assumption that the long photosensitive web 22 does not extend. Shall be. A pair of half-cut portions 34 a and 34 b formed with a width M are formed on the long photosensitive web 22 at intervals of a reference length of the photosensitive resin layer 28 attached to the glass substrate 24.

  Next, the long photosensitive web 22 is conveyed to the label adhering mechanism 40, and a predetermined application portion of the protective film 30 is arranged on the cradle 56. In the label adhering mechanism 40, a predetermined number of adhesive labels 38 are adsorbed and held by the adsorbing pads 54b to 54g, and each adhering label 38 straddles the remaining portion B of the protective film 30, and the front peeling portion A and the rear peeling portion A. Are integrally bonded to each other (see FIG. 3).

  For example, as shown in FIG. 1, the long photosensitive web 22 to which seven adhesive labels 38 are bonded is continuously connected to the peeling mechanism 44 after the tension on the delivery side is prevented via the reservoir mechanism 42. To be transported. In the peeling mechanism 44, the flexible base film 26 of the long photosensitive web 22 is sucked and held by the suction drum 62, and the protective film 30 is peeled off from the long photosensitive web 22 leaving the remaining portion B. Is done. The protective film 30 is peeled off via the peeling roller 63 and wound around the protective film take-up portion 64 (see FIG. 1).

  Under the action of the peeling mechanism 44, after the protective film 30 is peeled off from the flexible base film 26 leaving the remaining portion B, the tension of the long photosensitive web 22 is adjusted by the tension control mechanism 66, Next, in the photographing unit 47, an image of the long photosensitive web 22 including the half cut portion 34a and the reference piece 67 is photographed at a predetermined photographing timing.

  The image information acquired by the imaging unit 47 is calculated by the image inspection control panel 120 in the amount of displacement of the half-cut portion 34a, and then the laminator control panel 122 corrects the feed amount of the long photosensitive web 22. Is done. Details of the correction processing in the image inspection control panel 120 and the laminator control panel 122 will be described later.

  The long photosensitive web 22 that has passed through the photographing section 47 is conveyed to the attaching mechanism 46, whereby the photosensitive resin layer 28 is transferred (laminated) to the glass substrate 24.

  In the pasting mechanism 46, the rubber rollers 80a and 80b are initially set in a separated state, and the half-cut portion 34a of the long photosensitive web 22 is positioned at a predetermined position between the rubber rollers 80a and 80b. The conveyance of the long photosensitive web 22 is temporarily stopped. In this state, when the tip of the glass substrate 24 heated to a predetermined temperature by the substrate heating unit 74 constituting the substrate supply mechanism 45 is carried between the rubber rollers 80a and 80b by the transport unit 76, the action of the pressure cylinder 84 is achieved. The backup roller 82b and the rubber roller 80b are raised below, and the glass substrate 24 and the long photosensitive web 22 are sandwiched between the rubber rollers 80a and 80b with a predetermined pressing pressure. The rubber rollers 80a and 80b are heated to a predetermined laminating temperature.

  Next, when the drive motor 140 is driven via the motor control unit 138 under the control of the laminator control unit 136, the rubber rollers 80a and 80b rotate, and the glass substrate 24 and the long photosensitive web 22 are moved in the direction of the arrow Y. Be transported. As a result, the photosensitive resin layer 28 is heated and melted and transferred (laminated) to the glass substrate 24.

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

  When the lamination of one sheet of the long photosensitive web 22 is completed on the glass substrate 24, the rotation of the rubber rollers 80a and 80b is stopped, while the glass substrate 24 on which the long photosensitive web 22 is laminated is stopped. The leading end portion of a certain photosensitive laminate 100 is clamped by the substrate transport roller 92. At this time, a half-cut portion 34b is disposed at a predetermined position between the rubber rollers 80a and 80b.

  Then, the rubber roller 80b is retracted in a direction away from the rubber roller 80a to release the clamp, and the rotation of the substrate transport roller 92 is started again at a low speed, so that the photosensitive laminated body 100 moves the protective film 30 in the arrow Y direction. After being transported by a distance corresponding to the width M of the remaining portion B and the next half-cut portion 34a being transported to a predetermined position near the lower portion of the rubber roller 80a, the rotation of the rubber rollers 80a and 80b is stopped. In addition, the process which conveys the elongate photosensitive web 22 only between the half cut site | parts 34a and 34b is called "inter-substrate feeding" below.

  On the other hand, in the above state, the next glass substrate 24 is conveyed toward the attaching position via the substrate supply mechanism 45. The photosensitive laminated body 100 is continuously manufactured by repeating the above operation.

  At that time, as shown in FIG. 4, each end of the photosensitive laminate 100 is covered with the remaining portion B of the protective film 30. Therefore, when the photosensitive resin layer 28 is transferred to the glass substrate 24, the rubber rollers 80a and 80b are not soiled by the photosensitive resin layer 28.

  The photosensitive laminate 100 laminated by the attaching mechanism 46 is separated by cutting the long photosensitive web 22 between the glass substrates 24 by the cutter mechanism 48. The separated photosensitive laminate 100 is provided with a flexible base film 26. After the flexible base film 26 is peeled off together with the protective film 30 between the glass substrates 24, the next processing is performed. Supplied to the process.

  Next, according to the flowchart shown in FIG. 6, the feed amount correction processing for the long photosensitive web 22 will be described.

  First, the operator designates correction conditions using the operation display unit 134 such as a touch panel (step S1).

  In this case, the operation display unit 134 designates, for example, the number of photosensitive laminates 100 as the correction condition, and instructs the laminator control panel 122 to start the correction process from the photosensitive laminates 100 after the designated number. Can be directed. By specifying this correction condition, it is possible to efficiently manufacture the photosensitive laminate 100 without performing correction at the beginning of manufacture in which the manufacturing apparatus 20 is adjusted with high accuracy.

  Further, the frequency for performing the correction process can be designated as the correction condition. For example, whether the correction processing is performed by feeding back the positional deviation amount of the half-cut portion 34a calculated by the image inspection control panel 120 to the laminator control panel 122 every time, the average value of the calculated positional deviation amounts is obtained, and the average value thereof It is possible to specify the frequency of the correction process, such as whether the correction process is performed once every several times, or whether the correction process is performed by calculating the positional deviation amount once.

  Further, as a correction condition, an allowable range is set for the calculated positional deviation amount, and correction processing is performed only when the positional deviation amount is within the allowable range. If the positional deviation amount is outside the allowable range, for example, the operation display unit 134 It is possible to make a warning or the like and designate such that the operation of the manufacturing apparatus 20 is temporarily stopped.

  After the correction conditions are specified, the half-cut control unit 130 captures the half-cut portion 34 a formed on the long photosensitive web 22 by the processing mechanism 36 with respect to the shutter control unit 124 of the image inspection control panel 120. A prescribed pulse number corresponding to the prescribed feed amount until the reference position of the unit 47 is reached is set (step S2). In this case, the prescribed number of pulses precedes, for example, on the condition that the long photosensitive web 22 does not expand and contract while the half-cut portions 34a and 34b move from the processing mechanism 36 to the reference position of the imaging unit 47. It can be set as the number of pulses of the pulse signal output from the rotary encoder 51 until the next half-cut part 34a reaches the position of the half-cut part 34a.

  Therefore, the half-cut control unit 130 controls the processing mechanism 36 to form the half-cut portions 34a and 34b on the long photosensitive web 22 (step S3), and simultaneously outputs a pulse count start signal to the rotary encoder 51. The rotary encoder 51 starts counting the number of pulses (step S4).

  Next, the long photosensitive web 22 in which the half cut portions 34 a and 34 b are formed is transported, and the half cut portion 34 a reaches the photographing region 142 (see FIGS. 7 and 8) of the photographing unit 47, and the rotary encoder 51. When the number of pulses counted in step S2 matches the specified number of pulses set in step S2 (step S5), the shutter control unit 124 outputs a shutter signal to the CCD camera 72.

  At this time, the two-dimensional light source 69 is driven to illuminate the long photosensitive web 22 with the illumination light, and the image of the long photosensitive web 22 including the reference piece 67 and the half-cut portion 34a in the imaging region 142 is converted into the CCD. The image is taken by the camera 72 (step S6). The image captured by the CCD camera 72 is transmitted as image information to the image processing unit 126, and is subjected to predetermined image processing, whereby position information of the reference piece 67 and the half-cut portion 34a is acquired (step S7). ). The acquired positional information is transmitted to the positional deviation amount calculation unit 128, and the positional deviation amount ΔK of the position of the half-cut portion 34a with respect to the reference position set with reference to the reference piece 67 is calculated (step S8, FIG. 7). FIG. 8).

  The calculated positional deviation amount ΔK of the half-cut portion 34a is transmitted to the control pulse correction unit 132, and then the number of inter-substrate feed pulses is corrected according to the correction condition specified by the operation display unit 134 (Step S9, S10). In addition, when the half cut part 34a is detected every time and correction processing is not performed, the processing of steps S3 to S9 is repeated according to the number of times the correction processing is skipped.

  The inter-substrate feed pulse number corrected by the control pulse correction unit 132 is transmitted to the laminator control unit 136. The laminator control unit 136 controls the drive motor 140 via the motor control unit 138 based on the transmitted number of inter-substrate feed pulses (step S11), and adjusts the inter-substrate feed amount.

  FIG. 9 is an explanatory diagram of the laminate control of the long photosensitive web 22 and the inter-substrate feed control based on the corrected inter-substrate feed pulse number.

  The laminator control unit 136 performs laminating in a state where the half-cut portion 34a of the long photosensitive web 22 is aligned with the position of the tip of the glass substrate 24 shifted by the distance K shown in FIG. Lamination 1), the conveyance of the long photosensitive web 22 is temporarily stopped. Next, according to the corrected inter-substrate feed pulse number, the long photosensitive web 22 is fed between the substrates at a low speed, so that the next half-cut portion 34a is set at a predetermined position between the rubber rollers 80a and 80b. Thereafter, the glass substrate 24 is supplied between the rubber rollers 80a and 80b, and the long photosensitive web 22 is again laminated on the glass substrate 24 (step S12, laminate 2).

  Here, when performing the inter-substrate feeding process, as shown in FIG. 7, when the position of the half-cut portion 34a is displaced toward the processing mechanism 36 by the positional deviation amount ΔK, the inter-substrate feeding is performed according to the positional deviation amount ΔK. The number of pulses is increased, and the inter-substrate feed control is performed with the pattern 144a in FIG. Further, as shown in FIG. 8, when the position of the half-cut portion 34a is shifted to the rubber rollers 80a and 80b by the positional shift amount ΔK, the number of inter-substrate feed pulses is reduced according to the positional shift amount ΔK, and Inter-substrate feed control is performed with the pattern 144b.

  By performing the inter-substrate feed control in this way, the position of the half cut portion 34a with respect to the glass substrate 24 can be adjusted to a desired position, and the high-quality photosensitive laminate 100 can be manufactured. Moreover, since the adjustment process of the attachment position of the elongate photosensitive web 22 with respect to the glass substrate 24 can be performed without stopping the operation | movement of the manufacturing apparatus 20, manufacturing the photosensitive laminated body 100 efficiently. Can do. Further, the position of the imaging unit 47 is set to an arbitrary position between the processing mechanism 36 and the pasting mechanism 46 by adjusting the number of inter-substrate feed pulses corresponding to the set feed amount of the half-cut portions 34a and 34b. can do.

It is preferable. The pre-peeling unit 206 includes a peeling bar 214 that can move up and down between the glass substrates 24.

  After the glass substrate 24 and the long photosensitive web 22 laminated in the attaching mechanism 46 are cooled by the cooling mechanism 202, the long photosensitive web 22 between the glass substrates 24 constitutes the pre-peeling portion 206. It is pushed upward by the peeling bar 214, whereby a part of the flexible base film 26 is peeled from the photosensitive resin layer 28. Next, the glass substrate 24 to which the photosensitive resin layer 28 is adhered is conveyed in the direction of arrow Y, while the flexible base film 26 is wound around the winding shaft 210 via the peeling roller 208, which is possible.
