Fig. 1 is a diagram illustrating a laminated film 30 according to a first embodiment. Fig. 1(a) is a cross-sectional view of the laminated film 30, and fig. 1(b) is a plan view of the laminated film 30.

The laminated film 30 is a long film in which the adhesive film 10 and the release film 20 are laminated (see fig. 1 (a)).

The adhesive film 10 is a cover film (Coverlay film) having a thermosetting adhesive material layer 14 on one surface of a cover film body 12 (hereinafter, the adhesive film 10 is also referred to as a cover film 10). Before the adhesive film 10 is peeled off from the release film 20, a groove is formed at a predetermined interval in the adhesive film 10, thereby forming an adhesive film sheet 10a (see fig. 1 (b)). When peeling is performed, the adhesive film 10a is peeled off and then adhered to the member to be adhered 40.

The release film 20 is made of PET resin and is a film for protecting the surface of the adhesive material layer 14.

The adhesive layer 14 and the release film 20 are tightly bonded in a laminated state after air between the layers is exhausted, and the release film 20 can be peeled from the adhesive film 10 when the adhesive layer 14 comes into contact with air at normal temperature.

The member to be bonded 40 is a long film-like member, and is transported in a Roll-to-Roll (Roll) by a member to be bonded supply unit 200 (described later). The member to be bonded 40 is a flexible wiring board on which a conductor pattern is formed.

2. Structure of film sticking apparatus 1 according to the first embodiment

Next, the film sticking apparatus 1 according to the first embodiment will be explained.

Fig. 3 is a diagram for explaining the film sticking apparatus 1 according to the first embodiment. Fig. 3(a) is a plan view of the film sticking apparatus 1, and fig. 3(b) is a front view of the film sticking apparatus 1. In fig. 3(a), for convenience of explanation, the first image pickup device 342 and the second image pickup device 343 are not shown.

Fig. 4 is a plan view for explaining the

image pickup elements

342 and 343 and the

coupling parts

344 and 345 according to the embodiment.

Fig. 5 is a diagram for explaining the operation of the roller 311 in the first embodiment. Fig. 5(a) is a schematic view of the roller 311 located at the end of the pasted film sheet, and fig. 5(b) is a schematic view showing a state when the roller 311 rotates.

As shown in fig. 2 and 3, a film sticking apparatus 1 according to an embodiment includes: a laminated film supply unit 100, a member to be bonded supply unit 200, and a bonding unit 300. The laminated film supply unit 100, the member to be bonded supply unit 200, and the bonding unit 300 are all disposed on the same base B.

As shown in fig. 2 to 4, the laminated film supply unit 100 includes: the supply roll 120 for supplying the laminated film 30, the take-up roll 130 for taking up the release film 20 after peeling the cover film 10 from the laminated film 30, and the drive mechanism section (not shown) supply the laminated film 30 to a predetermined peeling area 112 (see fig. 5) on a peeling table 320 (described later) along a predetermined laminated film supply path 110 (see fig. 3 a) in a roll-to-roll manner.

The laminated film supply path 110 is a single transport path from the supply roller 120 to the winding roller 130 through the peeling stage of the pasting unit 300, through which the laminated film 30 (release film 20) is wound (see fig. 3 a).

The laminated film supply unit 100 is disposed on one base 160 (see fig. 2 and 3(b)) together with a peeling table 320 described later, and is movable in the θ direction (see the arrow in fig. 3) or the x and y directions as a whole. In this way, the position and posture (angle and height) of the set of the laminated film supply unit 100 and the peeling table 320 can be adjusted.

The feed roll 120 and the take-up roll 130 are positioned above a peeling table 320 (see fig. 2 and 3(b)) described later. This is because it is necessary to avoid the feed roller 120 and the winding roller 130 from touching other portions when the base 160 is moved by the posture control section described later, or to avoid the influence on the operability due to the narrow space between the feed roller 120 and the winding roller 130.

3. Operation of the film bonding apparatus 1 according to the first embodiment (film bonding method according to the first embodiment)

Next, an operation of the film laminating apparatus 1 according to the first embodiment (a film laminating method according to the first embodiment) will be described.

Fig. 6 is a flowchart of a film attaching method according to an embodiment.

Fig. 7 and 8 are sectional views for explaining the step of attaching the adhesive film sheet in the first embodiment. Fig. 7(a) to 7(c) and fig. 8(a) to 8(c) are process diagrams.

As shown in fig. 6, a film bonding method according to an embodiment includes: a laminated film supply step; a member to be bonded supply step; a pre-stripping process; a step of forming a bonded film; and a step of sticking the film.

The laminated film supply step is a step of supplying the laminated film 30 in which the adhesive film 10 and the release film 20 are laminated, along a predetermined laminated film supply path 110.

First, the laminated film supply section 100 releases the laminated film 30 from the supply roller 120, and conveys the laminated film 30 to a region (peeling region) for peeling the adhesive film 10 from the release film 20.

The member-to-be-bonded supplying step is a step of supplying the member-to-be-bonded 40 along the member-to-be-bonded supplying path 210 and arranging the member-to-be-bonded 40 in the bonding region 212 for bonding the bonding film sheet 10a to the member-to-be-bonded 40. In the member-to-be-bonded supplying step, the member-to-be-bonded 40 may be arranged in the bonding region 212 before the bonding film sheet 10a is bonded to the member-to-be-bonded 40. For example, the lamination film supplying step may be performed before, between the lamination film supplying step and the preliminary peeling step, between the preliminary peeling step and the adhesive film sheet forming step, or after, or during the lamination film supplying step, the preliminary peeling step, or the adhesive film sheet forming step. In the pasting film sheet joining step, the joining film sheet 10a may be fed to the member to be joined supplying step (for example, at the stage of peeling the pasting film sheet 10a) as long as it is before the pasting film sheet 10a is pasted to the member to be joined 40 by the roller 311.

Next, the pre-peeling section 350 forms a groove in the laminated film 30 at a predetermined interval to form the adhesive film 10a (adhesive film forming step). Then, the laminated film 30 on which the adhesive film sheet 10a is formed is transferred to the peeling area.

Next, the roller 311 is rotated to move across between the laminated film supply path 110 and the member to be bonded supply path 210, and the adhesive film sheet 10a formed on the adhesive film 10 is peeled off from the release film 20 and then the adhesive film sheet 10a is bonded to the member to be bonded 40 (adhesive film sheet bonding step). The specific process of the adhesive film sheet adhering process is as follows.

(1) First, the roller 311 is disposed at the end of the laminated film 30 disposed in the peeling area 112 opposite to the member-to-be-bonded supply path 210 (see fig. 5 a and 7 a).

(2) Subsequently, the roller 311 is moved toward the member-to-be-bonded supply path 210. In this way, the adhesive film sheet 10a is separated from the release film 20 and the adhesive film sheet 10a is transferred to the surface of the roller 311 (see fig. 7 (b)). That is, the roller 311 moves the adhesive film sheet 10a toward the adhesive area 212 while peeling off the adhesive film sheet 10 a.

(3) Subsequently, the roller 311 is further rotated to transfer the entire adhesive film sheet 10a to the surface of the roller 311, and the roller 311 is further rotated to transfer the adhesive film sheet 10a to the adhesive region (see fig. 7 c). At this time, in the first embodiment, the end of the adhesive film 10a which is peeled off first is located at a position rotated by a half circumference or more from the other end which is peeled off later. At this time, the roller 311 rotates from the peeling table 320 to the pasting table 330, but the peeling table 320 and the pasting table 330 are continuous in side view, and therefore the height position of the roller 311 hardly changes.

(4) Next, the roller 311 is further rotated to transfer the adhesive film sheet 10a to the to-be-adhered member supply path 210 (see fig. 8 a). When the portion of the adhesive film sheet 10a first peeled off from the release film 20 comes to a position just below the surface of the roller 311 after one rotation, the position is also just at the starting position for adhering the adhesive film sheet 10a to the member to be adhered 40.

(5) Next, the roller 311 is further rotated to attach the attachment film sheet 10a to the member to be attached 40 (see fig. 8 a). At this time, since the bonding stage 330 is being heated by the heater 336, the adhesive layer 14 on the bonding film 10a is melted and cured, and the bonding film 10a can be bonded to the member to be bonded 40.

At this time, after the laminated film 30 is conveyed, the laminated film supply unit 100 positions the region where the adhered film sheet 10a has not been peeled off on the peeling region 112.

(6) Subsequently, the roller 311 is further rotated to attach the entire attachment film sheet 10a to the member to be attached 40 (see fig. 8 b).

(7) Subsequently, the roller 311 is moved upward from the pasting member 40 by the vertical movement mechanism, and then the roller 311 is moved to the side of the laminated film supply path 110 by the width direction movement mechanism (not shown) (see fig. 8 c).

At this time, the member to be bonded 40 to which the bonding film sheet 10a is bonded is conveyed to the bonding region 212 by the member to be bonded supply unit 200 while the member to be bonded 40 to which the bonding film sheet 10a is not bonded is conveyed. Then, the adhered member 40 is positioned at the adhering area 212.

At this time, the roller 311 is positioned above the peeling region 112 on the laminated film supply path 110.

(8) Next, the roller 311 is again lowered to the end portion of the laminated film 30 opposite to the member-to-be-bonded supply path 210 (see fig. 7 a).

By repeating the above steps, the adhesive film sheet 10a can be efficiently adhered to the member to be adhered 40, and the member to be adhered 40 to which the adhesive film sheet 10a is adhered can be mass-produced.

4. Effects of the film sticking apparatus 1 and the film sticking method according to the first embodiment

According to the first embodiment, the film sticking apparatus 1 includes: a laminated film supply section 100 for supplying a laminated film 30 in which a sticking film 10 and a release film 20 are laminated, along a predetermined laminated film supply path 110; and a bonded member supply unit 200 that supplies the bonded member 40 along the bonded member supply path 210 parallel to the laminated film supply path 110, so that the bonding film 10 and the bonded member 40 do not overlap each other, and positioning of the bonding film 10 and the bonded member 40 in a state where they overlap each other is avoided, as in the conventional film bonding apparatus 900, and the bonding film 10 and the bonded member 40 can be bonded with high positioning accuracy.

According to the film sticking apparatus 1 of the first embodiment, since the roller 311 capable of moving across between the laminated film supply path 110 and the member to be stuck 210 is provided, and the sticking film sheet 10a formed on the sticking film 10 can be peeled from the release film 20 by the rotating roller 311 and then stuck to the member to be stuck 40, it is possible to complete the following operations in a continuous and integrated manner: a step of peeling off the adhesive film sheet 10a, a step of transferring the adhesive film sheet 10a to the member to be adhered 40, and a step of adhering the adhesive film sheet 10a to the member to be adhered 40. Therefore, it is not necessary to perform positioning in a state of temporarily stopping before transferring the adhesive film sheet to a pre-pressure bonding stage, fixing the release film by a chuck, or adhering the adhesive film sheet to the member to be adhered, as in the conventional film adhering apparatus 900. This can shorten the working time and efficiently attach the attachment film sheet 10a to the member to be attached 40.

Therefore, according to the film sticking apparatus 1 of the first embodiment, the film (sticking film sheet) can be efficiently stuck to the member to be stuck while maintaining high positioning accuracy.

Further, according to the film sticking apparatus 1 of the first embodiment, since the roller 311 can be repeatedly moved on the same path due to the above-described configuration, positional displacement is less likely to occur in this case, and therefore, even when mass production of the member to be stuck 40 to which the sticking film sheet 10a is stuck is required, the sticking film sheet 10a can be efficiently stuck to the member to be stuck 40.

Further, according to the film laminating apparatus 1 of the first embodiment, since the above configuration is provided, it is not necessary to dispose a chuck and a pre-press stage for holding the laminating film at the time of peeling, and it is possible to prevent the film laminating apparatus from being enlarged. Further, since the peeling, transfer, and attachment of the adhesive film sheet 10a can be performed only by rotating the roller 311, it is not necessary to dispose a mechanism such as an angle sensor on the roller 311, and the peeling, transfer, and attachment of the adhesive film sheet 10a can be performed with a relatively simple arrangement.

In addition, in the case where the sticking film sheet 10a is peeled, transferred, and stuck by suction, wrinkles may be generated when the sticking film sheet 10a is sucked, and warpage or positional deviation may occur when the sticking film sheet 10a is stuck to the member to be stuck 40, but according to the film sticking apparatus 1 according to the first embodiment, since the sticking roller is used, the peeling, transfer, and sticking of the sticking film sheet 10a can be completed without sucking the sticking film sheet 10 a. Thus, wrinkles are not generated in the adhesive film sheet 10a, and warping or positional displacement is not likely to occur when the adhesive film sheet 10a is adhered to the member to be adhered 40.

According to the film laminating apparatus 1 of the first embodiment, since the surface of the peeling table 320 and the surface of the laminating table 330 are flush with each other, there is no difference in level between the surface of the peeling table 320 and the surface of the laminating table 330, and the roller 311 can be smoothly moved. In this way, the transfer roller 311 does not cause wrinkles or creases in the adhesive film 10 a.

According to the film laminating apparatus 1 of the first embodiment, since the peeling stage 320 and the laminating stage 330 are disposed apart from each other, even when the position and the posture of one of the laminated film supply path 110 and the member-to-be-laminated supply path 210 are adjusted, the other one does not interfere with each other. In this way, when the positional deviation of the pasting film piece 10a needs to be corrected, only one of the laminated film supply path 110 and the pasted member supply path 210 needs to be adjusted, and the positional deviation of the pasting film piece 10a can be corrected under relatively simple conditions.

According to the film laminating apparatus 1 of the first embodiment, since the peeling table 320 and the laminating table 330 are continuous in a side view, the roller 311 is always positioned on the surface of the peeling table or the laminating table when the roller 311 is rotated, and the height position of the roller 311 can be maintained at a constant level. Thus, wrinkles or creases are less likely to occur when the adhesive film sheet 10a is transferred to the surface of the roller 311.

According to the film sticking apparatus 1 of the first embodiment, since the protruding portion 322 is provided on one of the peeling table 320 and the sticking table 330, and the recessed portion 332 having a space in which the protruding portion 322 can rotate is provided on the other, even when the position and the posture of one of the laminated film supply path 110 and the stuck member supply path 210 are adjusted, the effect that the other one does not interfere with each other can be achieved with a relatively simple configuration.

According to the film laminating apparatus 1 of the first embodiment, the laminating portion 300 includes: a first imaging element 342 capable of imaging a predetermined region of the adhesive film sheet 10a peeled from the release film 20; a second imaging element 343 capable of imaging an area corresponding to an area where the first imaging element 342 can image, of the area where the adhesive film 10a is adhered to the member to be adhered 40; and an attitude control section that adjusts the position and attitude of the adhesive film sheet 10a adhered to the member to be adhered 40 by adjusting one of the group of the laminated film supply section 100 and the peeling table 320 and the group of the member to be adhered supply path 210 and the adhering table 330, so that the adhesive film sheet 10a can be adhered to the member to be adhered 40 with higher positioning accuracy.

According to the film laminating apparatus 1 of the first embodiment, since the first image pickup device 342 and the second image pickup device 343 are coupled to each other, the position of the imaging area of the image pickup device can be adjusted more easily than when the image pickup devices are individually moved. In addition, with such a configuration, even when the attachment film sheets 10a having different widths (lengths in the direction along the laminated film supply path) need to be attached to the member to be attached 40, the position of the imaging region of the imaging element can be easily adjusted.

According to the film sticking apparatus 1 of the first embodiment, since the length from the end position on the sticking film sheet 10a on the opposite side to the member-to-be-stuck supply path 210 when the sticking film sheet 10a is peeled from the release film 20 to the end position on the laminating film supply path 110 side on the sticking film sheet 10a when the sticking film sheet 10a is stuck to the member to be stuck 40 is an integral multiple (one time) of the circumference of the roller 311, the sticking film sheet 10a can be peeled, transferred, and stuck in a state where the positioning is performed to some extent by rotating the roller 311, and further, even in the case where the sticking film is stuck to the member to be stuck several times, the large-scale positioning is not necessary. This can further shorten the working time and efficiently bond the adhesive film to the member to be bonded.

According to the film sticking apparatus 1 of the first embodiment, since the roller 311 is rotatable in the direction perpendicular to the member-to-be-stuck supply path 210 in plan view, the rotation of the roller 311 can be prevented from interfering with the supply (conveyance) of the member-to-be-stuck 40. In this way, for example, the roll 311 is positioned on the side of the laminated film supply path 110 to peel off the adhered film sheet 10a, and the adhered member 40 can be supplied (conveyed), thereby efficiently advancing the work.

According to the film sticking apparatus 1 of the first embodiment, since the sticking portion 300 satisfies W ≧ L, the sticking film piece 10a does not protrude from the roller 311, and the sticking film piece 10a can be stuck to the member to be stuck 40 with high positioning accuracy.

According to one embodiment, a film attaching method includes: the adhesive film sheet joining step of moving the roller 311 between the laminated film supply path 110 and the member to be joined supply path 210, peeling the adhesive film sheet 10a formed on the adhesive film 10 from the release film 20, and joining the same to the member to be joined 40 can be completed in a single continuous and integrated operation: a step of peeling off the adhesive film sheet 10a, a step of transferring the adhesive film sheet 10a to the member to be adhered 40, and a step of adhering the adhesive film sheet 10a to the member to be adhered 40. Therefore, it is not necessary to perform positioning in a state of temporarily stopping before transferring the adhesive film sheet to a pre-pressure bonding stage, fixing the release film by a chuck, or adhering the adhesive film sheet to the member to be adhered, as in the conventional film adhering apparatus 900. This can shorten the working time and efficiently attach the attachment film sheet 10a to the member to be attached 40.

According to one embodiment, a film attaching method includes: a laminated film supply step of supplying the laminated film 30 in which the adhesive film 10 and the release film 20 are laminated along a predetermined laminated film supply path 110; and a member-to-be-bonded supplying step of supplying the member-to-be-bonded 40 along the member-to-be-bonded supplying path 210 arranged in parallel with the laminated film supplying path 110, so that the adhesive film and the member-to-be-bonded do not overlap each other, and positioning of the adhesive film and the member-to-be-bonded in a state where they overlap each other is avoided, as in the conventional case, and the adhesive film sheet 10a can be bonded to the member-to-be-bonded 40 with high positioning accuracy.

According to the film joining method of the first embodiment, since the joining film sheet joining step is included, the roller 311 can be repeatedly moved in the same path. Thus, even when mass production of the member to be bonded 40 to which the adhesive film sheet 10a is bonded is required, positional deviation is less likely to occur, and the adhesive film sheet 10a can be bonded to the member to be bonded 40 more efficiently.

[ second embodiment ] to provide a medicine for treating diabetes

Fig. 9 is a diagram for explaining the roller 311a in the second embodiment. Fig. 10 is a diagram for explaining a non-adhesive roll cover winding step in the second embodiment. Fig. 10(a) and 10(b) are process diagrams.

The film laminating apparatus (not shown) according to the second embodiment has basically the same configuration as that of the film laminating apparatus according to the first embodiment, but is different from the film laminating apparatus according to the first embodiment in the configuration of the roller. That is, in the film bonding apparatus according to the second embodiment, a roller in which the non-adhesive roller cover 316 is wound around the end portions of both ends in the rotation axis direction is used as the roller 311a (see fig. 9). It is preferable that the width of the roller 311a around which the non-adhesive roller cover 316 is wound is set to be larger than the width of the adhesive film sheet 10 a.

The non-adhesive roll cover 316 is a roll cover wound with an elongated non-adhesive film. The material of the non-adhesive roller shell 316 is, for example, polyethylene. The width of the area of the roller 311a where the non-adhesive roller cover 316 is not wound corresponds to the width of the adhesive film sheet 10 a.

The film attaching method according to the second embodiment includes: the non-adhesive sleeve winding step is a step of winding the non-adhesive sleeve 316 around the ends of both ends of the roller 311a in the rotation axis direction, before the laminated film supplying step and the member-to-be-bonded supplying step (when the bonding of the bonded film sheets is required to be performed a plurality of times, before the first laminated film supplying step and the member-to-be-bonded supplying step).

First, a non-adhesive long film as the non-adhesive sleeve 316 is disposed on a path along which the roller 311a on the peeling stage 320 and the pasting stage 330 rotates, specifically, on a portion of the roller 311a around which the non-adhesive sleeve 316 is wound (see fig. 10 (a)). Next, the roller 311a is rotated to wind the non-adhesive sleeve 316 around the surface of the roller 311a (see fig. 10 b). This completes the preparation of the roller 311a in which the non-adhesive roller shell 316 is wound around the end portions of both ends in the rotation axis direction. Then, the same steps as those in the first embodiment are performed.

When the width of the roll is larger than the width of the adhesive film sheet 10a, the image pickup device moving mechanism 346 moves each image pickup device to a predetermined position before and after the non-adhesive roll cover winding step.

As described above, although the film joining apparatus according to the second embodiment differs from the film joining apparatus 1 according to the first embodiment in the roller configuration, since the film joining apparatus according to the first embodiment has the roller 311a capable of moving across between the laminated film supply path 110 and the member to be joined supply path 210 as in the film joining apparatus 1 according to the first embodiment, and can join the film sheet 10a formed on the joining film 10 to the member to be joined 40 after peeling the joining film sheet 10a from the release film 20 by rotating the roller 311a, it is possible to complete the following operations in a continuous and integrated manner: a step of peeling off the adhesive film sheet 10a, a step of transferring the adhesive film sheet 10a to the member to be adhered 40, and a step of adhering the adhesive film sheet 10a to the member to be adhered 40. Therefore, it is not necessary to perform positioning in a state of temporarily stopping before transferring the adhesive film sheet to a pre-pressure bonding stage, fixing the release film by a chuck, or adhering the adhesive film sheet to the member to be adhered, as in the conventional film adhering apparatus 900. This can greatly reduce the working time and efficiently bond the bonding film sheet 10a to the member to be bonded 40.

According to the film sticking apparatus of the second embodiment, since the roller 311a is a roller in which the non-adhesive roller cover 316 is wound around the end portions of both ends in the rotation axis direction, there is no possibility that: when the adhesive film sheet 10a is peeled off from the release film 20, the adjacent adhesive film sheets 10a (the adhesive film sheet to be peeled off next) are erroneously peeled off together, or when the adhesive film sheet 10a is adhered to the member to be adhered 40, the adhesive film sheet 10a adhered to the member to be adhered 40 is erroneously peeled off.

According to the film attaching method of the second embodiment, the film attaching method includes: the non-adhesive sleeve winding step winds the non-adhesive sleeve 316 around the ends of the roller 311a at both ends in the rotation axis direction before the laminated film supplying step and the member-to-be-bonded supplying step, and therefore the non-adhesive sleeve can be wound around the ends of the roller at both ends in the rotation axis direction in a simpler manner. In this way, the attachment film sheets having different widths in the direction along the laminated film supply path can be attached to the member to be attached without replacing the rollers.

Further, the film joining apparatus and the film joining method according to the second embodiment have the same configurations as the film joining apparatus 1 and the film joining method according to the first embodiment except for the configuration of the roller, and therefore have the effects of the film joining apparatus 1 and the film joining method according to the first embodiment.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention. For example, the following modifications may be implemented.

(1) The number, material, shape, position, size, and the like of the constituent elements described in the above embodiments are merely examples, and thus various modifications can be made within the scope not impairing the effect of the present invention.

(5) In the above embodiments, the heater 336 is provided on the pasting table, but the present invention is not limited to this. Since heating is not necessary as long as the adhesive film having adhesiveness at normal temperature is used, a heater may not be provided on the application table.

(6) In the above embodiments, the posture control unit adjusts the set of the laminated film supply unit 100 and the peeling table 320, but the present invention is not limited to this. The posture control unit may adjust the set of the member-to-be-bonded supply unit 200 and the bonding stage 330.

(7) In the above embodiments, the peeling stage having the convex portion protruding toward the pasting stage side at the central portion is used, but the present invention is not limited to this.

The term "recess" as used herein refers not only to a groove-like recess, but also refers to a recess having a portion recessed from the distal end portion toward the inside.

(8) In the above embodiments, the laminated film supply section and the member-to-be-bonded supply section of the roll-to-roll system are used, but the present invention is not limited to this. A non-roll-to-roll type laminated film supply unit and a member-to-be-bonded supply unit may be employed. In this case, the adhered film forming portion Half-cuts (Half-cuts) the laminated film 30, but the laminated film may be cut entirely.
