Description

System and method for attaching resin film

The present invention relates to a system and method for attaching a resin film, and more particularly, to a system and method for continuously attaching a resin film to a fixed sheet body having a predetermined shape.

While synchronizing the rotational speed of the take-up roller and the affixing roller of the carrier film, the carrier film on which the optical film is formed through the adhesive is placed inside and folded back with a peeling means, and the optical film is peeled from the carrier film together with the adhesive. A continuous production system (RTP (roll-to-panel) system) of an optical display panel in which the resulting optical film is continuously affixed to an optical cell via an adhesive is known (for example, see Patent Document 1 below).

In this RTP system, bubbles may be generated between the optical cell and the optical film due to warpage or vibration of the optical film, particularly at the initial stage of sticking. Therefore, an RTP system has been proposed that reduces the occurrence of air bubbles by reducing the warpage and vibration of the optical film at the initial stage of bonding by starting the affixing before the start of winding of the carrier film, or by setting the affixing speed higher than the winding speed (for example , See Patent Documents 2, 3, etc.).

However, in such an RTP system, since a large tension is applied to the optical film at the time of sticking, warping occurs in the optical display panel obtained as a result of sticking. Therefore, the RTP system that reduces the occurrence of air bubbles and suppresses the warpage of the optical display panel obtained as a result of sticking by starting the sticking before the start of winding in the initial stage of sticking, or by making the sticking speed higher than the winding speed and then making the sticking speed less than the take-up speed. Has been proposed (see, for example, Patent Documents 2 and 4).

Japanese Patent Laid-Open No. 2004-338408 Japanese Patent Laid-Open No. 2013-186184 Japanese Patent No. 5140788 Publication Japanese Patent No. 55868734 Publication

In this RTP system as shown in Patent Documents 2 and 4, since the optical cell is supported by a support having a high rigidity such as a glass substrate, in the initial stage of bonding, before the start of winding, the bonding is started, or the bonding speed is set higher than the winding speed. Even if it is enlarged, warpage occurring in the optical display panel obtained as a result of attaching can be suppressed. However, when the optical cell is applied to an optical cell that does not have a support with high rigidity such as a glass substrate, for example, a flexible optical cell such as an organic EL display cell, warpage occurs in the optical display panel obtained as a result of bonding. . In addition, similarly, when such an RTP system is applied to a polarizing film, such as a retardation film having a predetermined shape, a brightness enhancing film, or the like, warpage occurs in the laminate obtained as a result of the affixing. That is, when the RTP system is applied to the affixing of a resin film such as a polarizing film or a protective film to a flexible fixed sheet body having a predetermined shape such as a flexible optical cell, a retardation film, and a brightness enhancing film, the resin obtained as a result of the affixing Warping occurs in the film laminate.

Therefore, it is an object of the present invention to provide a system and method for attaching a resin film to reduce the warpage of a fixed sheet body laminate obtained as a result of attaching in an RTP system for attaching a resin film to a fixed sheet body having a predetermined shape. Do it as one.

As a result of repeated intensive research in order to solve the above problems, the present inventors at least partially from the start of sticking to the end of sticking without increasing the speed of attaching the resin film to the fixed sheet body in the initial stage of attaching than the take-up speed of the carrier film. In the period of, even if the take-up speed was made larger than the sticking speed, or even if the coiling was started before the start of sticking, it found that there may be cases where no air bubbles are generated. That is, conventionally, in order to reduce the generation of air bubbles, it was considered necessary to increase the speed of attaching the resin film to the fixed sheet body at the initial stage of attaching than the speed of winding up of the carrier film, or to start attaching before the start of winding. However, as a result of increasing the tension generated in the resin film, such a method does not require that for a flexible fixed sheet body in which the tension generated in the resin film has a large effect, and in order to reduce the tension generated in the resin film during the affixing treatment. Because it causes warping in the resin film, even if the winding speed is increased from the start of the sticking to the end of the sticking, or if the winding is started before the start of sticking, no bubbles are generated, suppression of bubble generation and optical display panel We found that there is a case where suppression of the occurrence of the warpage of the body can be compatible.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)

1 is a schematic side view showing an entire resin film sticking system according to a first embodiment of the present invention. In the resin film sticking system 10, the resin film sheet 74 with an adhesive layer laminated so as to be peelable through an adhesive layer on a long strip-shaped carrier film 72 is peeled from the carrier film 72, and peeled off. The formed resin film sheet 74 with the pressure-sensitive adhesive layer and the flexible fixed sheet body (B) of a predetermined shape are affixed using a pair of attaching rollers 50 to successively manufacture the fixed sheet body laminate (BL). . The operation of each part of the resin film sticking system 10 can be controlled by the drive control unit 500. The resin film can be made into a polarizing film, a protective film, etc., and the flexible shaping sheet body of a predetermined shape can be made into a flexible optical cell, a retardation film, a brightness improvement film, etc.

In this embodiment, the shaping sheet body (B) is a shaping sheet body. 2 shows an example of the optical display cell 1 constituting the cell mother board B. The optical display cell 1 is a rectangular shape having a short side 1a and a long side 1b in planar shape, and a terminal portion 1c having a predetermined width is formed along one short side 1a. In this terminal portion 1c, a plurality of electrical terminals 2 for electrical connection are arranged. The area of the optical display cell 1 excluding the terminal portion 2 becomes the display area 1d. This display area 1d has a width W in a horizontal direction and a length L in a vertical direction. In order to implement the method of the present invention, the optical display cell 1 is preferably an organic EL display cell, but the method of the present invention can be applied as long as it is a display cell having a flexible thin film structure. The optical display cell 1 can have various screen sizes, from a relatively small one for use in a mobile phone, a smartphone, or a tablet to a relatively large one for use in a television.

3 is a perspective view schematically showing an example of a manufacturing process of an organic EL display cell having a relatively small display screen such as a smartphone or a tablet. In this step, first, a glass substrate 3 as a heat-resistant mother substrate is prepared, and a heat-resistant resin material, preferably a polyimide resin, is applied on the glass substrate 3 to a predetermined thickness and dried, thereby forming the resin substrate 4 Is formed. As a heat-resistant resin material, in addition to polyimide resin, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polycarbonate (PC), and the like can be used. Other materials for the substrate include a flexible ceramic sheet as described in Japanese Patent Application Laid-Open No. 2007-157501, or Japanese Patent Application Laid-Open No. 2013-63892, Japanese Patent Application Laid-Open No. 2010-13250, Japanese Patent Laid-Open No. 2013-35158 Flexible glass as described in the publication may also be used. In the case of using a flexible ceramic sheet or flexible glass as a base material, it is not necessary to use the glass substrate 3.

On the resin substrate 4, a plurality of organic EL display cells 1 are formed in a state arranged in a vertical and horizontal matrix shape by a known manufacturing method, so that the resin substrate 4 and the display cells are cell mother board (B). To form. Including the case where there is only one display cell formed on the resin substrate 4, these are referred to as a cell mother board. Thereafter, the surface protective film 5 is bonded to cover the organic EL display cell 1 formed on the resin substrate 4. Here, the state in which the cell mother board B is bonded to a heat-resistant substrate such as the glass substrate 3 is referred to as a mother board structure.

4A is a plan view showing an example of the cell mother board B to which the surface protective film 5 is not adhered, and FIG. 4B is a cross-sectional view taken along line bb in FIG. 4, but the surface protective film 5 is adhered thereto. It shows a state in which the cell mother board (B) is disposed on the glass substrate (3). As shown in Fig. 4A, in the cell mother board (B), a plurality of optical display cells (1) are arranged in a matrix so that the terminal portion (1a) faces in the horizontal direction and forms columns in the vertical direction and rows in the horizontal direction. do. The cell motherboard (B) has a rectangular shape having a short side (B-1) and a long side (B-2), as shown in Fig. 4A, and is located near both ends of one short side (B-1). The reference mark (m), which is the reference point, is attached by printing, engraving, or other suitable methods. This reference mark m is referred to as a reference when positioning the motherboard B. When the optical film is affixed, the cell mother board B is sent in the direction indicated by arrow A in Fig. 4A, that is, in the longitudinal direction.

The cell mother board B in a state having the glass substrate 3 is conveyed to a glass substrate peeling position where the glass substrate 3 is peeled by a transport mechanism such as the shaping sheet body transport mechanism 400 described later, and the glass substrate (3) is peeled from the resin substrate 4 by a known method such as laser irradiation. A technique for peeling a glass substrate from a resin substrate by laser irradiation is described in, for example, International Publication No. WO2009/104371.

The cell mother board B from which the glass substrate 3 has been peeled off is then conveyed to the affixing position of the affixing station 300 by the panel member conveying device 400.

The shaped sheet body conveying mechanism 400 has an adsorption fixing means 402 that fixes the shaped sheet body B in an adsorbed state. The adsorption fixing means 402 can adsorb and fix the upper surface of the shaped sheet body B by vacuum adsorption in the adsorption unit 404 under the control of the drive control device 500.

Since the shaping sheet body (B) has flexibility, a predetermined range (P) of the tip portion of the shaping sheet body (B) is forward from the most end portion 406 of the suction fixing means 402 as shown in FIG. 5A. It protrudes and is fixed so that the entire surface or almost the entire surface other than the predetermined range P is adsorbed. In this way, a through-hole type or a porous type can be used as an adsorption member capable of adsorbing a shaped sheet body such as the shaped sheet body (B) on the entire surface. In the case of the through-hole type, a hole diameter of 3 mm or less and a hole spacing (pitch) of 30 mm or less can be used. When the hole diameter is larger than 3 mm, there is a possibility that the suction force is too strong, and there is a possibility that there is a problem that traces of holes or stains are formed in the held shaped sheet body. When the hole spacing (pitch) is larger than 30 mm, there is a possibility that a problem that cannot be maintained due to excessively weak attraction force may occur. As the through-hole type adsorption member, for example, a vacuum gripper (FMC series) manufactured by SCHMALZ can be used. As a porous type adsorption member, for example, a vacuum adsorption chuck made by Nippon Tungsten Co., Ltd. (micropore diameter porous ceramics NPP-3D) or an ultra-high molecular weight polyethylene porous film (SUNMAP LC-T) made by NITTO DENKO CORPORATION can be used. have. The position where the suction fixing means 402 adsorbs the shaped sheet body B may be near the rear of the shaped sheet body B so that a predetermined range P can be secured. This predetermined range (P) is a portion disposed between the sticking roller 50 before the resin film sheet 74 with an adhesive layer and the fixed sheet body B are adhered by a pair of sticking rollers 50, as described later. And at least some of these portions are pinched by a pair of sticking rollers 50. The predetermined range P is 50 mm to 150 mm from the tip of the shaped sheet body B, preferably 60 mm to 100 mm. If the predetermined range P is larger than 150 mm, the shaped sheet body B is stretched by its own weight, and there is a fear of colliding inside the facility during transportation. If the predetermined range P is smaller than 50 mm, the shaping sheet body B cannot be reliably held by the affixing roller 50 described later.

As shown in Fig. 1, the shaped sheet body B is adsorbed and lifted from the upper surface by the adsorption fixing means 402 from the mounting table 201 on which the shaped sheet body B is loaded, and the adsorption fixing means ( It is fixed to 402 and conveyed toward the bonding part 200 in the state of being raised. The tip portion P of the shaped sheet body B is disposed between the pair of sticking rollers 50, and the shaped sheet body B is pinched by the pair of sticking rollers 50, and suction fixing means 402 After the fixation by is released (refer to FIG. 5B), the fixed sheet body (B) and the resin film sheet 74 with the pressure-sensitive adhesive layer sandwiched from the top and bottom by a pair of sticking rollers 50 are a pair of sticking rollers 50 It is sequentially bonded from the front to the rear by means of (see Fig. 5C).

The molded sheet body B conveyed to the affixing station 300 by the molded sheet body conveying mechanism 400 is in a state of being fixed by the molded sheet body conveying mechanism 400 under the control of the drive control unit 500. A predetermined range P of the tip portion is disposed between the pair of sticking rollers 50 (see Fig. 5B). The moving direction when the predetermined range P of the tip portion of the shaping sheet body B is disposed between the pair of sticking rollers 50 is not limited. In the present embodiment, the fixed sheet body conveying mechanism 400 moves the fixed sheet body B from a direction orthogonal to the rotational axis of the pair of attaching rollers 50 to move the predetermined range P to the pair of attaching rollers 50 Can be placed between.

The shaping sheet body B in which a predetermined range P of the tip portion is disposed between the pair of sticking rollers 50 by the shaping sheet body conveying mechanism 400 is a pair of operating under the control of the drive control unit 500. It is pinched from the upper and lower surfaces together with the tip portion of the resin film sheet 74 with an adhesive layer by the sticking roller 50 (see Fig. 5B). When the shaped sheet body B is pinched, the adsorption fixing means 402 releases the adsorption of the shaped sheet body B (see Fig. 5B). The fixation release by the suction fixing means 402 may be before the fixed sheet body B is pinched by the pair of attaching rollers 50, and in this case, the suction fixing means 402 is After the fixation is released, the shaping sheet body B can be supported in an unfixed state until it is pinched by the pair of sticking rollers 50. The timing at which the fixing by the suction fixing means 402 is released is not particularly limited as long as the posture of the shaping sheet body B does not change during the period from release to pinching by the sticking roller 50.

At a position corresponding to the entire lower surface except for a predetermined range P of the tip portion of the fixed sheet body B, in which a predetermined range P is disposed between the pair of affixing rollers 50, a support means 410 at the time of release is fixed. It is placed. When the fixing is released, the support means 410 is pinched by the pair of affixing rollers 50 and supports the shaped sheet body B in a state in which the suction fixing means 402 is separated from below.

When the support means 410 is installed when the fixing is released, the fixed sheet body B can be supported by the lower rollers of the pair of attaching rollers 50 and the support means 410 when the fixing is released. ) May be separated from the shaping sheet body B before the shaping sheet body B is pinched by the sticking roller 50. After the fixed sheet body B by the suction fixing means 402 is released, the suction fixing means 402 does not fix the fixed sheet body B until it is pinched by the pair of sticking rollers 50. In the case of supporting in an unfixed state, the adsorption fixing means 402 functions as the support means 410 when the fixing is released.

When the fixing is released, the support means 410 may be placed in a fixed position in advance, or only when it is necessary to support the fixed sheet body B, it appears below the fixed sheet body B, and it is necessary to support it. When not present, it can be configured to retreat to any one position.

The molded sheet body (B) is conveyed to the affixing station 300 by the molded sheet cell mother board conveying mechanism 400 and peeled from the carrier film 72 by the peeling member 60 ( 74) and affixed (see Fig. 5c). The affixing is clamped from the top and bottom by a pair of sticking rollers 50 in a state in which the tip of the adhesive layer-attached resin film 74 overlaps at a predetermined position in the front part of the forming sheet body B, and a pair of sticking rollers 50 By rotating in the reverse direction, each of the shaped sheet bodies B is sequentially performed from the front to the rear, and the shaped sheet body stack BL obtained as a result of the affixing is placed on the mounting table 202 adjacent to the affixing roller 50. It slides and is placed. The molded sheet body stack BL that has been pasted and placed on the mounting table 202 is conveyed in a direction away from the affixing station 300 by a transport mechanism similar to that of the molded sheet body conveying mechanism 400.

The resin film laminated body roll 70 is a rolled up long resin film laminated body 71 in a roll shape. The resin film laminate 71 is made of a resin film having a predetermined width direction dimension laminated on a carrier film 72 via an adhesive layer. The carrier film 72 is bonded to the outside of the resin film through an adhesive layer. The resin film laminate 71 is fed from the resin film laminate roll 72 by a pair of drive rolls 23 at a constant speed. In this embodiment, a resin film is a back surface protective film which becomes a lower surface bonding film. The lower surface-attached film is not limited to this, and can be any suitable film such as a composite film constituted as a laminate comprising a layer of a light-shielding film and a layer of a film having impact resistance and heat dissipation. This resin film 71 is in the shape of a long continuous web, but its width is a dimension corresponding to the width W of the shaped sheet body B in the transverse direction.

In addition, referring to FIG. 1, the resin film laminate 71 fed from the resin film laminate roll 70 by a pair of driving rollers 23 includes a guide roll 24 and a dancer roll 25 movable in the vertical direction. ), the guide roll 26 and the guide roll 27 are sent to the cutout forming mechanism 900. The cutout forming mechanism 900 includes a cutting blade 901 and a pair of drive rolls 29 for delivery disposed via a guide roll 28. This cutout forming mechanism 900 stops the drive roll 29 at the cutout formation position, operates the cutting blade 901 in a state in which the transfer of the resin film laminate 71 is stopped, and operates the carrier film 72 To form a cut in the width direction of only the resin film 73 with an adhesive layer. The spacing of cuts is a distance corresponding to the length L of the motherboard B in the longitudinal direction. Accordingly, the resin film 73 with the pressure-sensitive adhesive layer is cut in the width direction by cutting to form a resin film sheet 74 with an adhesive having a width W and a length L in the longitudinal direction of the mother board B. . In this way, a plurality of resin film sheets 74 with an adhesive layer are continuously formed on the carrier film 72, and these resin film sheets 74 with an adhesive layer are supported by the carrier film 72 and sent to the affixing position. .

The dancer roll 25 is biased downward, and a pair of driving rolls 23 that continuously drive the resin film stack 71 in the conveying direction, and the resin film stack 71 are conveyed at the time of cutting. It is an adjustment roll which acts so as to adjust the film feed between the pair of drive rolls 29 which stop and drive by a predetermined distance after the end of cutting. That is, in the stop period of the drive roll 29, the dancer roll 25 moves downward so as to absorb the conveyed portion of the drive roll 23 by the biasing force, and when the operation of the drive roll 29 starts, the above Due to the tensile force applied to the resin film laminate 71 by the drive roll 29, it resists the biasing force and moves upward.

A series of resin film sheets 74 with an adhesive layer formed by cutting are supported by the carrier film 72, and the dancer roll 30, guide roll 31, and guide roll ( 32), guide rolls 36, 37, 38, 39 through a pair of drive rollers, infeed roller 33, guide roll 34, and dancer roll 35 having the same configuration as the dancer roll 25. It is guided and sent to the affixing position of the affixing station 300.

In the present embodiment, the affixing station 300 is constituted by an affixing roller 50, a carrier film peeling mechanism 60, a support means 410 for releasing the fixing, and a mounting table 202. An affixing roller 50 and a carrier film peeling mechanism 60 are provided at the affixing position of the affixing station 300. The sticking roller 50 is movably arranged between the upper retracting position and the lower pressing position, and the resin film with an adhesive layer at the top of the continuous resin film sheets 74 with an adhesive layer supported by the carrier film 72 When the tip of the sheet 74 is aligned with the tip of the display cell 1 to be affixed, the resin film sheet 74 with the adhesive layer is pressed against the fixed sheet body (B) by holding them. Do.

The carrier film peeling mechanism 60 folds back the carrier film 72 at an acute angle at the affixing position, and a peeling member 61 that acts to peel the resin film sheet 74 with the adhesive layer at the head from the carrier film 72 It is equipped with. A carrier film take-up roll 40 is disposed to take up the carrier film 72 folded back at an acute angle. The carrier film 72 peeled from the adhesive layer-attached resin film sheet 74 is sent to the take-up roll 40 through the guide roll 41 and the outfeed roller 42, which is a pair of driving rolls, to the take-up roll 40. Is wound up.

Next, details of the affixing treatment in the present embodiment will be described. In this embodiment, the carrier film take-up mechanism is constituted by a carrier film take-up roll 40, a guide roll 41, and an outfeed roller 42. In the carrier film winding mechanism, the outfeed roller 42 may be omitted. The rotation of the carrier film winding roll 40 and the outfeed roller 42 is controlled by the drive control unit 500, but the rotation of the outfeed roller 42 in the affixing treatment of the resin film sheet 74 with an adhesive layer The speed corresponds to the winding speed V1. In this embodiment, the affixing mechanism is constituted by the affixing roller 50 which is a pair of drive rollers. The rotation of the sticking roller 50 is controlled by the drive control unit 500, but the rotational speed of the sticking roller 50 in the sticking treatment of the resin film sheet 74 with an adhesive layer is equivalent to the sticking speed V2. do. Fig. 6 is a diagram showing the speed relationship between the take-up speed V1 and the sticking speed V2 in the entire period of the sticking treatment in the present embodiment.

First, preparations for the affixing treatment are performed. When the carrier film 72 is wound by the outfeed roller 42, the tip of the resin film sheet 74 with the pressure-sensitive adhesive layer starts peeling from the carrier film 72, and the resin film sheet 74 with the pressure-sensitive adhesive layer is brought to the affixed position. Is sent (see Fig. 5A). At this time, the resin film sheet 74 with an adhesive layer is sent to the affixing position by the infeed roller 33. The resin film sheet 74 with the pressure-sensitive adhesive layer reaches the affixing position, and delivery is once stopped. At this time, the outfeed roller 42 also stops. Subsequently, as described above, the fixed sheet body B in which a predetermined range P of the tip portion is disposed between the pair of sticking rollers 50 by the fixed sheet body conveying mechanism 400 is It is pinched from the upper and lower surfaces together with the tip portion of the resin film sheet 74 with an adhesive layer by a pair of sticking rollers 50 operated under control (see Fig. 5B). When the shaped sheet body B is pinched, the adsorption fixing means 402 releases the adsorption of the shaped sheet body B.

The outfeed roller 42 is rotated at the starting point of bonding (Ts), and the carrier film 72 is peeled off by accelerating the take-up speed of the carrier film 72 with acceleration (a1), and the bonding roller 50 is rotated. And, by accelerating the bonding speed (V2) to the acceleration (a2) (a1> a2), sandwiching the resin film sheet 74 with the adhesive layer and the fixed sheet body (B) between the bonding rollers 50 and conveying the adhesive layer The attached resin film sheet 74 is affixed to the shaping sheet body (B).

Subsequently, the acceleration of the outfeed roller 42 is stopped at a point in time T1 to achieve a constant speed, after which the sticking roller 50 reaches the speed of the outfeed roller 42 at a point in time T2. The acceleration of the roller 50 is also stopped and the speed is set to a constant speed, and the winding speed V1 and the sticking speed V2 are synchronized (matched) until the time point T3 (V1 = V2).

At the time point (T3), the outfeed roller 42 and the sticking roller were decelerated at the same acceleration (a3), and the resin film sheet 74 with the pressure-sensitive adhesive layer was separated from the carrier film 72 and the resin film sheet with the pressure-sensitive adhesive layer ( 74) to the cell mother board (B) is completed. The outfeed roller 42 and the affixing roller 50 are stopped at the attaching completion time point Te (V1=V2=0). After that, it shifts to the next sticking preparation.

In this embodiment, the amount of movement of the carrier film 72 by winding of the outfeed roller 42 and the amount of movement of the resin film sheet 74 with an adhesive layer by the attaching roller 50 are from the time of attaching start (Ts). It differs only up to the time point T1. If the difference in the amount of movement from the starting time point (Ts) to the time point (T1) is too large, the curvature of the resin film sheet 74 with the pressure-sensitive adhesive layer increases, and bubbles are generated in the fixed sheet body layer (BL) obtained as a result of the sticking. do. Therefore, in the present embodiment, the acceleration a1 and a2 and the time from the time point Ts to the time point T1 of the affixing start time is set to a value at which no bubbles are generated in the shaped sheet body laminate BL.

According to the present embodiment, it is possible to achieve both the occurrence of warpage and suppression of the generation of air bubbles in the molded sheet body laminate obtained as a result of attaching in the RTP system in which the resin film is affixed to the flexible molded sheet body.

(Second embodiment)

Fig. 7A is a diagram showing the speed relationship between the winding speed V1 and the sticking speed V2 in the entire period of the sticking process in the present embodiment. In this embodiment, the difference from the first embodiment is the control method of the speed relationship between the take-up speed V1 and the affix speed V2 in the affixing process. The overlapping description of the first embodiment will be omitted.

The outfeed roller 42 and the affixing roller 50 are rotated at the same acceleration (a4) at the starting point of the affixing (Ts), and a resin film sheet 74 with an adhesive layer and a cell mother board (B) are placed between these rollers. The carrier film 72 is peeled off while conveying while sandwiching, affixing the resin film sheet 74 with an adhesive layer to the cell mother board (B) surface.

Subsequently, the acceleration of the affixing roller 50 is stopped at a time point T4 to make it a constant speed, and at a time point T5 after that, the acceleration of the outfeed roller 42 is stopped to make it a constant speed. Thereby, the take-up speed V1 of the outfeed roller 42 becomes larger than the sticking speed V2 of the sticking roller 50 after the time point T4. Here, if the take-up speed (V1) is too large than this affixing speed, the resin film bends or vibrates, so that the take-up speed (V1) and the affixing speed (V2) are bubbles in the fixed sheet body laminated body formed as a result of the affixing. A value that does not occur is set.

At the time point T6, the take-up speed V1 of the outfeed roller 42 was decelerates to the acceleration a5, and at the time point T7 when the speed was reduced to the same speed as the affixing speed V2 of the sticking roller 50 Peeling of the resin film sheet 74 with the adhesive layer from the carrier film 72 and the cell of the resin film sheet 74 with the adhesive layer by decelerating the attaching speed V2 of the attaching roller 50 to the same acceleration a5 Attaching to the mother board (B) is completed. The outfeed roller 42 and the affixing roller 50 are stopped at the attaching completion time point Te (V1=V2=0). After that, it shifts to the next sticking preparation.

In this embodiment, the amount of movement of the carrier film 72 by winding of the outfeed roller 42 and the amount of movement of the resin film sheet 74 with an adhesive layer by the sticking roller 50 are from the time point T4 to the time point ( T7) only differs. If the difference in the amount of movement from this point in time (T4) to the point in time (T7) is too large, the curvature of the resin film sheet 74 with the pressure-sensitive adhesive layer increases, and thus bubbles are formed in the molded sheet body obtained as a result of the affixing. Occurs. Therefore, in this embodiment, the time from the time point T4 to the time point T7 is set to a value at which no air bubbles are generated in the shaping sheet body shaped sheet body stacked body BL. In addition, the amount of movement of the carrier film 72 by winding of the outfeed roller 42 from the time point Ts to the time point T4, and the resin film sheet 74 with an adhesive layer by the attaching roller 50 Since the amount of movement is the same, if the time from the time from the start time to the time point (T4) or from the time point from the time point (T7) is too large, the resin film sheet 74 with the pressure-sensitive adhesive layer cannot be warped to reduce the tension. Their time is set to an appropriate value capable of suppressing the occurrence of warpage and generation of air bubbles in the shaped sheet body laminate.

In the above embodiment, the speed difference between the take-up speed V1 and the sticking speed V2 from the time point T5 to the time point T6 was constant, but it is not limited to this, for example, as shown in FIG. 7B. As described above, the pattern of the speed difference, such as a pattern in which the speed difference gradually decreases, may be an appropriate arbitrary pattern in which no bubbles are generated.

According to this embodiment, in the RTP system for attaching a resin film to a flexible fixed sheet body, it is possible to achieve both the occurrence of warpage and suppression of the generation of air bubbles in the shape-shaped sheet body laminate obtained as a result of bonding.

(Third embodiment)

Fig. 8 is a diagram showing the speed relationship between the winding speed V1 and the sticking speed V2 in the entire period of the sticking treatment in the present embodiment. In this embodiment, the difference from the first embodiment is the control method of the speed relationship between the take-up speed V1 and the affix speed V2 in the affixing process. The overlapping description of the first embodiment will be omitted.

At the start of winding (T8), the outfeed roller 42 is rotated prior to rotating the affixing roller 50, and the winding speed V1 is accelerated with an acceleration a6 to form a carrier from the resin film laminate 71. The film 72 is peeled off.

Thereafter, the affixing roller 50 is rotated at the affixing start point (Ts), accelerated at the same acceleration (a6), and the resin film sheet 74 with an adhesive layer and the cell mother board (B) are sandwiched between these rollers. It conveys and affixes the resin film sheet 74 with an adhesive layer to the cell mother board (B) surface. Here, if the timing of rotating the bonding roller is too late, the resin film bends or vibrates, so the difference or acceleration (a6) between the starting point of winding (T8) and the starting point of bonding (Ts) is the rear protective film (90) obtained as a result of bonding. A value at which air bubbles do not occur in the shaped sheet body B to which) is affixed is set.

Subsequently, the acceleration of the outfeed roller 42 is stopped at a point in time T9 to achieve a constant speed, after which the sticking roller 50 reaches the speed of the outfeed roller 42 at a point in time T10 The acceleration of the roller 50 is also stopped to a constant speed, and the take-up speed V1 and the sticking speed V2 are synchronized (matched) until the time point T11 (V1 = V2).

Deceleration of the outfeed roller 42 and the sticking roller 50 at the same acceleration (a7) at the time point (T11) to release the resin film sheet 74 with the pressure-sensitive adhesive layer from the carrier film 72 and the resin with the pressure-sensitive adhesive layer The affixing of the film sheet 74 to the cell mother board B is completed. The outfeed roller 42 and the affixing roller 50 are stopped at the attaching completion time point Te (V1=V2=0). After that, it shifts to the next sticking preparation.

In this embodiment, the amount of movement of the carrier film 72 by winding of the outfeed roller 42 and the amount of movement of the resin film sheet 74 with an adhesive layer by the sticking roller 50 are from the time point T8 to the time point ( T10) only differs. If the difference in the amount of movement from the starting time point (T8) to the time point (T10) is too large, the curvature of the resin film sheet 74 with the pressure-sensitive adhesive layer increases, and bubbles are generated in the fixed sheet body layer (BL) obtained as a result of attaching. do. Accordingly, in the present embodiment, the acceleration a6 or the time from the time point T8 to the time point T10 is set to a value at which no bubbles are generated in the shaped sheet body laminate BL.

According to this embodiment, in the RTP system for attaching a resin film to a flexible fixed sheet body, it is possible to achieve both the occurrence of warpage and suppression of the generation of air bubbles in the shape-shaped sheet body laminate obtained as a result of bonding.

At least during the period from the start of the affixing treatment to the completion of the affixing so that air bubbles are not generated in the structured sheet body laminate by combining control of the winding speed and the attaching speed of some or all of the first to third embodiments. In some cases, the outfeed roller 42 and the sticking roller 50 may be driven and controlled so that the take-up speed is greater than the sticking speed, and (2) the take-up speed becomes more than the sticking speed for a predetermined time from the start of the sticking treatment.

In the above embodiment, in the case of synchronizing the winding speed (V1) and the attaching speed (V2), when the rotation of the infeed roller 33 and the outfeed roller 42 is synchronized, the resin film sheet 74 with an adhesive layer is redundant. It is possible to suppress the occurrence of tension.
