Abstract

This film detachment device comprises a pre-detachment mechanism (700) that performs pre-detachment in order to make detachment of a film (Wc) from a base member (Wm) easier. The pre-detachment mechanism (700) performs: a first step in which, while a pre-detachment roll (710) is caused to be in contact with one side end section on the surface of the film (Wc), at least either the film (Wc) or the pre-detachment roll (710) is caused to travel such that the pre-detachment roll (710) rotates, and the film (Wc) is wound to a final winding position while being detached from the base member (Wm); and a second step after the first step, in which at least either the film (Wc) or the pre-detachment roll (710) is caused to travel in the opposite direction, in a state in which the pre-detachment roll (710) is in contact with the surface of the film (Wc), and the film that was wound on to the pre-detachment roll (710) is re-attached to the base member (Wm). As a result of this film detachment device, film can be reliably detached from base paper by using less force than used by conventional film detachment devices.

Description

Film peeling apparatus and film peeling method

The present invention relates to a film peeling apparatus and a film peeling method for peeling a film from a base member.

Generally, a flexible wiring board is made of a thin polyimide film or a polyester film as a base film, and a copper foil constituting an electronic circuit is stuck on the surface thereof. Further, electronic components are directly mounted on the electronic circuit, and the electronic circuit is further covered with a film (referred to as a coverlay film).

In addition, such a flexible wiring board is thin and soft, and can be bent freely. However, when a component is mounted on it or connected to a connector, it has a certain thickness and rigidity. May be necessary. Therefore, in order to ensure the rigidity of a part of the base film, a reinforcing plate having a predetermined shape and size is adhered to the base film.

In the process of manufacturing the flexible wiring board described above, as a step before attaching the coverlay film on the electronic circuit to be coated on the base film, first, the precut coverlay film is manually removed from the mount. It is necessary to peel off. The same applies to the reinforcing film, and it is necessary to manually peel the reinforcing film from the base member (hereinafter referred to as a mount). In the specification of the present invention, the “mounting paper” does not only indicate “paper” as a raw material, but also includes a material such as plastic.

Such manual peeling of the coverlay film and the reinforcing film from the mount has been a major obstacle to automating the production of flexible wiring boards. Accordingly, various film peeling devices that can mechanically peel films such as coverlay films and reinforcing films from the mount have been proposed.

However, even with this type of film peeling apparatus, it may not be possible to peel off the film from the backing sheet. Therefore, a preliminary peeling mechanism is provided, and a state in which a part of the film is previously peeled off from the mount (preliminary peeled state) by the preliminary peeling mechanism, and then the film is peeled off from the mount. There exists a peeling apparatus (for example, refer patent document 1).

FIG. 14 is a front view of a film peeling apparatus 9000 disclosed in Patent Document 1. As shown in FIG.
FIG. 15 is a plan view of a film peeling apparatus 9000 disclosed in Patent Document 1. As shown in FIG. 14 and 15, the film is described as a cover lay film.

As shown in FIGS. 14 and 15, a film peeling device 9000 disclosed in Patent Document 1 (hereinafter referred to as a conventional film peeling device 9000) is a cover that is detachably attached to a mount Wm. A lay film Wc (also referred to as a cover lay film with mount Wc) is provided along a base table 100 having a guide surface 110 substantially parallel to the traveling path A (see FIG. 15), and the guide surface 110 of the base table 100. The front side of the travel path A (in the direction of the arrow x, also referred to as “the front side of the travel path”) and the rear side of the travel path A (in the direction of the arrow x ′, also referred to as “the rear side of the travel path”). A movable peeling unit 200 that can reciprocate within a predetermined range, and a base table 100 on the rear side of the traveling path with respect to the movable peeling unit 200, is peeled off from the mount Wm. The pre-peeling mechanism 400 that performs pre-peeling for ease, and the cover-laid coverlay film Wc that has been preliminarily peeled are cut in a state in which the mount Wm is left in the direction orthogonal to the traveling path A, and a piece of the cut coverlay A cutting mechanism unit 600 that generates a film (referred to as a coverlay film piece) and a holding device 800 that can detachably hold one piece of the coverlay film piece cut by the cutting mechanism unit 600 are provided.

The preliminary peeling mechanism 400 includes a first peeling plate 410 and a second peeling plate 420 that are provided with the traveling path A in between. The first peeling plate 410 and the second peeling plate 420 are used in a state where the respective leading

end portions

411 and 421 are inserted by a predetermined length between the mount Wm and the coverlay film Wc.

In the conventional film peeling apparatus 9000, when the coverlay film Wc passes through the preliminary peeling mechanism 400, both side portions are preliminarily peeled from the mount Wm along the traveling path A, leaving a predetermined width at the center. Is set to

Further, the cutting mechanism unit 600 is provided with a preliminary peeling mechanism unit 660. When the cutting mechanism unit 600 generates a cover lay film piece, the preliminary peeling mechanism unit 660 uses a traveling path front side end portion (also referred to as a front end portion) of the cover lay film piece following the cover lay film piece. By adsorbing along the cutting line by the cutting blade 640, the tip of the coverlay film piece is preliminarily peeled by a predetermined amount. Thus, since the preliminary peeling mechanism part 660 preliminarily peels the front-end | tip part of a coverlay film piece, it is called the front-end | tip preliminary | backup peeling mechanism part 660.

In the film peeling apparatus 9000 configured as described above, first, the preliminary peeling mechanism unit 400 preliminarily peels both sides while leaving a center part in the longitudinal direction of the coverlay film, and then, When the cutting mechanism unit 600 cuts the cover lay film along the cutting line, the leading edge preliminary peeling mechanism unit 660 adsorbs the leading edge of the subsequent cover lay film along the cutting line, thereby removing the leading edge part. Preliminarily peel off.

In this way, one side of the coverlay film piece in which the both sides are preliminarily peeled off by the preliminarily peeling mechanism portion 400 and the leading edge preliminary peeling mechanism portion 660 is preliminarily peeled off is obtained by the movable peeling unit 200. Peel from the backing paper Wm. That is, the holding device 800 is lowered and the one piece of the coverlay film preliminarily peeled by the holding device 800 is pressed, and the movable peeling unit 200 is moved along the traveling path while applying a pulling force to the mount Wm to the front side of the traveling path. The cover lay film piece is peeled from the mount Wm by running backward. Note that peeling the coverlay film piece from the mount Wm by the movable peeling unit 200 may be referred to as “main peeling”.

In the conventional film peeling device 9000, when the cover lay film piece is peeled from the mount Wm by the movable peeling unit 200, the cover lay film piece is already preliminarily peeled from the mount Wm. Therefore, it has the outstanding effect that it can peel appropriately with a small force.

International Publication No. 2011/108332

However, even if the conventional film peeling apparatus 9000 includes the preliminary peeling mechanism (the preliminary peeling mechanism 400 and the tip preliminary peeling mechanism 660) as described above, the material of the coverlay film Wc and the mount Wm Depending on the material, and the type of adhesive that adheres the cover lay film Wc to the mount Wm, the cover lay film Wc is appropriately removed from the mount Wm when the cover lay film Wc is peeled off from the mount. It may not be possible to peel off.

Accordingly, an object of the present invention is to provide a film peeling apparatus and a film peeling method capable of reliably peeling a film from a mount with a smaller force than a conventional film peeling apparatus.

[1] The film peeling apparatus of the present invention is a film peeling apparatus for peeling the film from the base member in the film with a base member that is attached to the base member so that the film can be peeled. A pre-peeling mechanism for performing pre-peeling to facilitate peeling of the film when peeling from the base member, the pre-peeling mechanism having a pre-peeling roll to which the film can be attached; The pre-peeling mechanism is configured such that the pre-peeling roll is in contact with one end of the surface of the film, so that the pre-peeling roll is rotated so that the pre-peeling roll rotates. One side is run, and the rotation of the preliminary peeling roll causes the film to move from one side end on the surface of the film. A first step of winding the film while peeling it from the base member between the winding end position set before the other end of the surface and the winding after the first step. By causing at least one of the film with a base member or the preliminary peeling roll to run in a direction opposite to the running direction in the first step in a state where the preliminary peeling roll is in contact with the surface of the film from the removal end position. And a second step of re-sticking the film wound up by the preliminary peeling roll from the winding end position to the base member between one side end portions on the surface of the film. Is preliminarily peeled off from the base member.

According to the present invention, as a preliminary peeling operation, from the one side end on the surface of the film by the preliminary peeling roll to the winding end position set in front of the other side end on the surface of the film, After peeling the film from the base member, an operation of re-sticking the peeled film to the base member is performed.

By performing such preliminary peeling operation, the film is once peeled off from the base member from the one side end of the film to the winding end position. The adhesive strength of is almost released. For this reason, when the film is peeled from the base member, the film can be reliably peeled from the mount with a smaller force than the conventional film peeling apparatus. Thereby, a film can be appropriately peeled from a base member, without being influenced by the material of a film, the material of a base member, and also the kind of sticking agent.

[2] In the film peeling apparatus of the present invention, the winding end position is a position immediately before the other side end on the surface of the film, and the winding end position and the other side of the film surface. It is preferable that a non-preliminary peeling region where no preliminary peeling is performed exists between the end portions.

Thus, since the preliminary peeling roll preliminarily peels most of the film, when actually peeling the film from the base member, the film can be reliably peeled from the mount with a smaller force. Moreover, since a non-preliminary peeling area exists in the film, it is possible to prevent a problem that the film is peeled off from the base member before the main peeling.
Moreover, since a non-preliminary peeling area exists in the film, when the second step is performed, the film which has been preliminarily peeled will be correctly attached to the original position. In other words, if there is no non-preliminary peeling area in the film, there may be a problem that when the second step is performed, the film that has been preliminarily peeled off is not correctly attached to the original position. Such a problem can be prevented by the presence of the non-preliminary peeling region.

[3] In the film peeling apparatus of the present invention, the preliminary peeling roll is a cylindrical roll having an adhesive portion on the surface, and the film is attached to the preliminary peeling roll by the adhesive force of the adhesive portion. It is preferable to perform winding.

Since the preliminary peeling roll has such a structure, it is possible to reliably perform an operation of peeling from the base member from one end of the film to the winding end position.

[4] In the film peeling apparatus of the present invention, it is preferable that the adhesive portion is provided on the entire surface of the preliminary peeling roll.

Since the adhesive portion is provided on the entire surface of the preliminary peeling roll, it is possible to reliably perform the operation of attaching the film to the preliminary peeling roll.

[5] In the film peeling apparatus of the present invention, the preliminary peeling roll is a cylindrical roll having a suction port for sucking the film on the surface, and the inside of the preliminary peeling roll has a negative pressure. It is preferable to wind the film by adhering the film to the preliminary peeling roll by a suction force.

In the preliminary peeling roll having such a structure, the film can be adsorbed to the preliminary peeling roll by a suction force by a negative pressure. For this reason, even with the preliminary peeling roll of such a structure, the operation | movement which peels from the one side edge part of a film to the winding completion position from a base member can be performed reliably. In addition, the preliminary | backup peeling roll which adheres a film with the suction force by a negative pressure is also called "suction type preliminary | backup peeling roll."

[6] In the film peeling apparatus of the present invention, the suction port is preferably provided along the width direction of the preliminary peeling roll.

The suction type pre-peeling roll having such a structure makes it possible to reliably perform the operation of attaching the film to the suction type pre-peeling roll and winding it. The suction port may be one in which a long hole is formed along the width direction of the preliminary peeling roll, or a plurality of small holes are formed in the width direction of the preliminary peeling roll. Also good.

[7] In the film peeling apparatus of the present invention, the diameter of the preliminary peeling roll is equal to or greater than the length of the circumference of the preliminary peeling roll from the one side end on the surface of the film to the winding end position. It is preferable to set so as to be.

By setting the diameter of the preliminary peeling roll (including the suction type preliminary peeling roll) in this way, when the preliminary peeling roll performs the operation of winding the film, the film is wound before the preliminary peeling roll finishes one rotation. Can be taken. Thereby, winding of a film can be performed efficiently.

In addition, since the film can be taken up before the preliminary peeling roll finishes one rotation, for example, in the case where the preliminary peeling roll is a preliminary peeling roll provided with an adhesive portion on the entire surface, When the preliminary peeling roll performs the operation of winding the film, the surface of the preliminary peeling roll is always in contact with the surface of the film, so that the dust adhering to the surface of the film is attached to the side of the preliminary peeling roll. Can do. Thereby, according to the preliminary peeling roll of such a structure, the effect which cleans the surface of a film is also acquired.

[8] In the film peeling apparatus of the present invention, the film with a base member is a long sheet-like film with a base member, and the long film with a base member travels along a traveling path. A base table having a guide surface for supporting the base member side when traveling from the road rear side to the road front side, and a cutting blade provided in a direction crossing the road, A cutting mechanism section that cuts a long base member-attached film that travels along a travel path while leaving the base member, and generates a film piece having a predetermined dimension in a direction along the travel path; The preliminary peeling mechanism section includes the one end portion on the surface of the film piece as the traveling path front side, and the other end portion on the surface of the film piece as the traveling path rear side. It is preferred to pre-peeling the film pieces from the base member by performing the second step and the first step with respect Irumu piece.

This is a film in which a long film-like film with a base member is cut with the cutting mechanism section leaving the base member, and then a film piece generated by cutting the cutting mechanism section is peeled off by the peeling mechanism section. It is a peeling device. In such a film peeling apparatus, the film piece can be preliminarily peeled by performing the first step and the second step on the film piece generated by the cutting mechanism. Thereby, when each film piece is peeled from the base member, the film can be reliably peeled from the mount with a small force.

[9] In the film peeling apparatus of the present invention, the film with a base member is formed into a long sheet shape and is cut into predetermined dimensions along the longitudinal direction with the base member remaining. The film is a film with a cut base member that exists on the base member as a plurality of film pieces, and the cut film with the base member travels from the rear side of the travel path along the travel path. A base table having a guide surface for supporting the base member side when traveling on the road front side is further provided, and the preliminary peeling mechanism portion performs preliminary peeling at the present time among the plurality of film pieces. One side end of the surface of the film piece to be performed is the front side of the traveling path, and the other side of the surface of the film piece to be preliminarily peeled at the present time The part as said running path rear side, it is preferable to pre-peeling the film pieces from the base member by performing the second step and the first step with respect to the filmstrip.

This uses, as a film with a base member, a film with a base member that has been cut (a film with a base member that has been pre-cut) that has been cut for each predetermined dimension in the direction along the travel path with the base member remaining. It is. Even in such a cut film with a base member, each film piece can be preliminarily peeled by performing the first step and the second step on each film piece. Thereby, when each film piece is peeled from the base member, the film can be reliably peeled from the mount with a small force.

[10] In the film peeling apparatus of the present invention, it has a peeling portion for peeling the preliminarily peeled film piece from the base member, and the travel path along the guide surface of the base table. A movable peeling unit capable of reciprocating within a predetermined range on the front side and the rear side of the traveling path, and the film piece on which the preliminary peeling has been made when the movable peeling unit peels off the film piece on which the preliminary peeling has been made. A holding device that can be freely held, and when the movable peeling unit travels to the rear side of the traveling path, the movable peeling unit can travel to the rear side of the traveling path of the movable peeling unit. The movable peeling unit is placed in a state in which a force to resist is applied to the base member, and the pre-peeled film piece is held by the holding device. By running the serial roadway rear side, it is preferable to peel off the base member from the filmstrip.

In the film peeling apparatus described in [8] or [9] above, the movable peeling unit for peeling the preliminarily peeled film piece from the base member and the preliminarily peeled film piece are detachably held. And a holding device having a holding plate to be used. Even in the film peeling device having such a configuration, after the preliminary peeling is performed by performing the first step and the second step on the film piece. Since the film piece is actually peeled from the base member by the peeling unit, the film piece can be peeled from the base film with a small force.

When performing such a main peeling operation, if the preliminary peeling with the preliminary peeling roll is not performed, the stress is applied to the film piece when the base film is about to be peeled off from the film piece. The piece may be wrinkled, and the quality of the film piece may be deteriorated.

On the other hand, according to the film peeling apparatus of the present invention, the part from the one side end on the surface of the film piece to the winding end position is once peeled from the base member by the preliminary peeling roll. Therefore, the adhesive force with the base film is almost released. For this reason, when the base film is peeled from the film piece, the stress applied to the film piece is almost negligible. Thereby, when performing this peeling operation | movement, the malfunction of "a wrinkle may arise in a film piece" can be prevented reliably, and the quality deterioration of a film piece can be prevented beforehand.

[11] In the film peeling apparatus of the present invention, the film is provided on the rear side of the traveling path from the preliminary peeling mechanism, and the film is moved to the rear side of the traveling path from the front end of the traveling path of the film piece. It is preferable to further include a tip preliminary peeling mechanism for preliminarily peeling by a predetermined amount.

By adopting such a configuration, the preliminary peeling operation by the preliminary peeling roll can be more reliably performed. That is, the leading edge pre-peeling mechanism part preliminarily peels the traveling path front side end (tip part) of the film piece by a predetermined amount, and thus the traveling path front end (tip part) of the film piece. By preliminarily exfoliating a predetermined amount, preliminary exfoliation by the preliminarily exfoliating roll can be performed more reliably.

[12] The film peeling method of the present invention is a film peeling method for peeling the film from the base member in the film with a base member in which the film is attached to the base member so as to be peelable. When peeling from the base member, it has a pre-peeling step for performing pre-peeling for facilitating the peeling of the film, and the pre-peeling step is configured such that the pre-peeling roll is placed on one side of the film surface. In this state, at least one of the film with a base member or the preliminary peeling roll is run so that the preliminary peeling roll rotates, and the rotation of the preliminary peeling roll starts from one end on the surface of the film. Between the end of the other side on the surface of the film and the winding end position set before this The first step of winding the film while peeling it from the base member, and after the first step, in a state where the preliminary peeling roll is in contact with the surface of the film from the winding end position, By running at least one of the base member-attached film or the preliminary peeling roll in the direction opposite to the running direction in the first step, the film wound by the preliminary peeling roll is removed from the winding end position from the winding end position. The film is preliminarily peeled from the base member by performing the second step of re-sticking to the base member between the one side end portions of the film.

According to the film peeling method of the present invention, the same effect as the film peeling apparatus of the present invention described in [1] can be obtained. The film peeling method of the present invention preferably has the same characteristics as those of the film peeling apparatus of the present invention described in [2] to [11] above.

A delivery mechanism 910 for delivering the cover lay film Wc with mount, and the mount W from which the cover lay film Wc has been peeled off And a take-up mechanism 920 for taking up the.

Note that the travel path A does not exist as a component, but virtually shows an area in which the cover-attached coverlay film Wc travels. In FIG. 2, the travel path A is shown in light gray.

The gantry 120 is installed along the guide surface 110 on the guide surface 110 of the base table 100. Two parallel linear guide rails 131 and 132 (see FIG. 2) are installed on the gantry 120 at a predetermined interval.

The movable peeling unit 200 includes a movable plate 210 capable of reciprocating along the

guide rails

131 and 132 in the traveling path front side and the traveling path rear side, and a cutting support base 220 fixed to the upper surface side of the movable plate 210. And a peeling portion 230 (details will be described later) provided at the end portion of the cutting support base portion 220 on the front side of the traveling path. The cutting support base 220 supports the cover lay film Wc with mount from the lower side when cutting the cover lay film Wc with mount, and the traveling path front side and the traveling path rear side together with the movable plate 210.

The cutting blade 640 cuts the cover lay film Wc with mount in a state where the mount Wm is left in the direction orthogonal to the travel path A, but when cutting the cover lay film Wc, the cover lay film Wc is surely secured. In order to make it possible to cut the mount Wm, the mount Wm is set so that it can be lowered to a level that slightly cuts into the mount Wm without being cut.

The cutting mechanism unit 600 configured as described above cuts the cover-laying cover-lay film Wc in a direction perpendicular to the travel path A with the mount Wm left, and in a direction along the travel path A, a predetermined length A piece of coverlay film having dimensions is produced.

The preliminary peeling mechanism unit 700 includes a preliminary peeling roll 710, a support plate 720 that rotatably supports the preliminary peeling roll 710, and an elevating drive unit (not shown) that raises and lowers the preliminary peeling roll 710 in the arrow zz ′ direction. And have.

The preliminary peeling roll 710 has an adhesive force on the entire surface in the film peeling apparatus 1000 according to the first embodiment. For example, rubber having an adhesive force is formed into a roll shape. The preliminary peeling roll 710 can be reciprocated in the vertical direction (arrow z-z ′ direction) by a drive mechanism (not shown).

The preliminary peeling roll 710 is normally positioned so as to be in a non-contact state with the coverlay film Wc (in this case, the coverlay film piece generated by the cutting mechanism unit 600), and performs a preliminary peeling operation. In some cases, it descends and contacts the coverlay film piece. Then, by moving the cover lay film Wc with the mount within the predetermined range to the front side and the back side of the travel path, the preliminary peeling roll 710 rotates on the cover lay film piece, and the cover lay film piece is peeled from the mount Wm. While performing the winding operation. This operation will be described later.

The preliminary peeling roll 710 is not rotated by the power of a motor or the like, but is rotated when the coverlay film Wc with mount travels along the travel path while being in contact with the coverlay film Wc with mount. It is.

In addition, the preliminary peeling roll 710 has adhesive strength, and the adhesive strength of the preliminary peeling roll 710 rotates on the coverlay film piece with the preliminary peeling roll 710 in contact with the coverlay film piece. It is assumed that the adhesive strength is such that it can be taken up while being peeled off from the mount.

The holding device 800 is a suction holding device that sucks and holds the coverlay film piece that has been subjected to preliminary peeling (referred to as suction holding). Therefore, the holding device 800 is hereinafter referred to as an adsorption holding device 800.

As shown in FIG. 1, the suction holding device 800 is capable of reciprocating along the arrow zz ′ direction and along a traverse line (not shown) (a line in the arrow yy ′ direction in FIG. 2). So that it can reciprocate. A suction plate 810 is provided on the tip surface (surface facing the traveling path A) of the suction holding device 800. A suction mechanism unit 820 is provided on the upper end side of the suction plate 810. The suction mechanism unit 820 is provided with a negative pressure suction pipe 821 connected to a negative pressure generator (not shown).

In addition, a large number of mesh-like negative pressure suction ports (not shown) are provided on the lower end surface (surface facing the traveling path A) of the suction plate 810, and these negative pressure suction ports are negative. It leads to the pressure suction pipe 821. Therefore, when the negative pressure generating device is operated, the negative pressure suction port is in a negative pressure suction state, and the coverlay film piece that has traveled to the position of the suction holding device 800 can be sucked.

The delivery mechanism unit 910 includes a delivery reel 911 on which a cover-laying cover film Wc to be delivered is mounted, a turning roll 912, and a tension roll 913 interposed between the delivery reel 911 and the turning roll 912. is doing. On the other hand, the take-up mechanism 920 is interposed between the take-up reel 921, the nip roll 922, the turning roll 923, the take-up reel 921 and the nip roll 922, which takes up the backing sheet Wm from which the coverlay film Wc has been peeled off. Tension roll 924.

A leading film Wa having a predetermined length is connected to one end portion (end portion on the front side of the traveling path) of the coverlay film Wc with mount mounted on the feeding reel 911, and the leading film Wa is fed out. After the feed reel 911 of the mechanism unit 910 is turned in the horizontal direction by the turning roll 912 via the tension roll 913 and passes through the guide surface 110 of the base table 100, it is lowered by the turning roll 923 of the take-up mechanism unit 920. And is wound around a take-up reel 921 via a nip roll 922 and a tension roll 924. The leading film is followed by a backing sheet (mounting sheet with the coverlay film Wc peeled off) Wm.

FIG. 3 is a diagram showing the configuration of the cover-lay film Wc with mount. The cover lay film Wc with a mount is attached to a long mount Wm made of a polyethylene resin, a polyester resin or a mylar film so that the cover lay film Wc made of a polyimide resin or a polyester resin can be peeled off. It has a configuration.

FIG. 4 is a diagram showing a configuration of the peeling portion 230. As shown in FIG. 4, the peeling unit 230 supports the lower surface (surface on the traveling path A side) of the mount Wm so that the entire width direction of the mount Wm (arrow yy ′ direction in FIG. 2) is slidable. 231 and an inclined surface 232 that forms an acute angle θ (preferably around θ = 45 degrees) with respect to the horizontal plane 231. A mount folding portion 233 is formed at the tip of the peeling portion 230 (the connection portion between the horizontal surface 231 and the inclined surface 232).

Since the peeling unit 230 has such a configuration, the mount Wm travels in the direction of the arrow x while being in contact with the horizontal surface 231 of the peeling unit 230, and then is turned by the mount folding unit 233 by 90 degrees or more. The direction is changed by the roll 260 and the vehicle travels in the horizontal direction. In addition, it is preferable that the peeling unit 230 is made of a material having a small friction coefficient (for example, a material such as Teflon (registered trademark)) so that the mount Wm can travel smoothly in a sliding contact state.

Note that when the cover lay film Wc (in this case, the cover lay film piece that has been subjected to preliminary peeling) is peeled from the mount Wm, the movable peeling unit 200 travels in the direction indicated by the arrow x ′ (rear side of the running path). When performing, the suction holding device 800 (not shown in FIG. 4) is in a lowered state, and is in a state of holding and holding the coverlay film piece that has been preliminarily peeled.

Next, the operation of the film peeling apparatus 1000 according to Embodiment 1 will be described.
5 and 6 are diagrams schematically illustrating the overall operation of the film peeling apparatus 1000 according to the first embodiment. In FIG. 5 and FIG. 6, illustration of components unnecessary for explanation is omitted. For this reason, it is simplified from FIGS. 1 and 2. The same components as those in FIGS. 1 and 2 are denoted by the same reference numerals.

FIG. 7 is a diagram for explaining in detail the preliminary peeling operation by the preliminary peeling roll 710 of the preliminary peeling mechanism unit 700 in the overall operation of the film peeling apparatus 1000 according to the first embodiment shown in FIGS. 5 and 6. is there. FIG. 7 shows an enlarged view of the preliminary peeling roll 710 and the coverlay film Wc with mount, and illustration of components unnecessary for the description is omitted.

Hereinafter, the operation of the film peeling apparatus 1000 according to the first embodiment will be described with reference to FIGS.

First, the leading film Wa connected to the coverlay film Wc with mount is set so that the leading end of the leading film Wa is taken up by the take-up reel 921. And as for the coverlay film Wc with mount following the said leading film Wa, one side edge part (it is also called the traveling path front side edge part) E1 of the said coverlay film Wc with mount is the movable peeling unit 200 as an initial setting. Is set so as to be positioned at the tip of the peeling portion 230, that is, the mount folding portion 233 (see FIG. 4) (see FIG. 5A). At this time, in the state of FIG. 5A, the suction holding device 800 is in the raised position (position not in contact with the support base 270) as shown in FIG. 5A.

In the state shown in FIG. 5A, when the cutting mechanism 600 performs a cutting operation, the coverlay film Wc is cut and a coverlay film piece is generated. This cover lay film piece (the cover lay film piece on the front side of the traveling path from the cutting blade 640) is defined as a first cover lay film piece Wc1. The first coverlay film piece Wc1 is a coverlay film piece that is a target for preliminary peeling at the present time.

Further, in this case, the size L1 (referred to as coverlay film size L1) along the travel path of the individual coverlay film pieces generated by the cutting operation by the cutting mechanism unit 600 is equal to that of the backing paper folding unit 233 of the peeling unit 230. It is assumed that it substantially corresponds to the distance from the position to the cutting blade 640. The coverlay film size L1 can be arbitrarily set within a predetermined range by setting the travel amount of the movable peeling unit 200.

And the preliminary peeling mechanism part 700 performs the preliminary peeling operation | movement with respect to the 1st coverlay film piece Wc1. This will be described with reference to FIGS.
Prior to starting the preliminary peeling operation, the movable peeling unit 200 travels by a predetermined amount from the state of FIG. 5A to the rear side of the traveling path (in the direction of the arrow x ′). At this time, the preliminary peeling roll 710 is not in contact with the first coverlay film piece Wc1. Moreover, the cutting mechanism part 600 exists in the raise position. In addition, the state of each clamping device at this time is “open” in the first clamping device 500 and “closed” in both the second clamping device 240 and the third clamping device 250.

In this state, the preliminary peeling roll 710, the cutting mechanism unit 600, and each clamping device (the first clamping device 500, the second clamping device 240, and the third clamping device 250) are configured as shown in FIG. When traveling from the state to the rear side of the travel path (in the direction of the arrow x ′), the first coverlay film piece Wc1 also travels rearward of the travel path together with the movable peeling unit 200.

And the board | substrate folding | returning part 233 of the peeling part 230 in the movable peeling unit 200, ie, the traveling path front side edge part E1 as one side edge part in the surface of the 1st coverlay film piece Wc1, becomes directly under the preliminary peeling roll 710. The movable peeling unit 200 stops once at the position. This state is shown in FIG. In the state of FIG. 7A, the preliminary peeling roll 710 descends and the preliminary peeling roll 710 comes into contact with the front end E1 on the surface of the first coverlay film piece Wc1 (FIG. 7B). reference.).

In addition, the code | symbol E2 in FIG. 7 shows the cutting part of the cover-lay film Wc at the time of performing cutting operation by the cutting mechanism part 600 in FIG. 5A, and this cutting part E2 is a preliminary peeling object at this time. It becomes the other side end portion on the surface of the first cover lay film piece Wc1, that is, the traveling path rear side end portion E2. And the traveling path rear side edge part E2 in the surface of the 1st coverlay film piece Wc1 is the one side edge part of the coverlay film piece (it is set as the 2nd coverlay film piece Wc2) used as a preliminary | backup peeling next, ie ,. It becomes the traveling road front side end. Hereinafter, the traveling road front side end may be abbreviated as “front side end”, and the traveling path rear side end may be abbreviated as “rear side end”.

In this way, when the preliminary peeling roll 710 comes into contact with the surface of the front end E1 on the surface of the first coverlay film piece Wc1 (the state shown in FIG. 7B), the movable peeling unit 200 is moved forward of the travel path. Go to the side. As a result, as shown in FIG. 7C, the preliminary peeling roll 710 rotates on the surface of the first coverlay film piece Wc1, and winds up while peeling off the first coverlay film piece Wc1 from the mount Wm. I do.

And the traveling of the movable peeling unit 200 stops at the position P1 (see FIG. 7D) where the preliminary peeling roll 710 winds up the first coverlay film piece Wc1 by a predetermined amount. “Position P1” is referred to as “winding end position P1”.

Thus, when the preliminary peeling roll 710 winds up the cover lay film piece Wc1, among the cover lay film size L1, leaving a predetermined length ΔL from the winding end position P1 to the rear side end E2, The length L2 from the front end E1 to the winding end position P1 is set to be wound. The predetermined length ΔL is expressed as “non-winding length ΔL”, and the length from the front end E1 of the coverlay film piece Wc1 to the winding end position P1 is referred to as “winding length L2”. It may be written. Further, the region of the first coverlay film piece Wc1 corresponding to the non-winding length ΔL is referred to as “non-preliminary peeling region”, and the region of the first coverlay film piece Wc1 corresponding to the winding length L is “ This is referred to as “preliminary peeling region”.

Then, from the state of FIG. 7D, this time, the movable peeling unit 200 travels again to the rear side of the traveling path. Thereby, the preliminary peeling roll 710 performs the operation | movement which returns the coverlay film piece once wound up on a base_sheet | mounting_paper. Then, when the movable peeling unit 200 reaches the front end E1 on the surface of the second coverlay film piece Wc1 (see FIG. 7E), the preliminary peeling roll 710 rises to the state shown in FIG. Return to the state shown.

After the preliminary peeling roll 710 in the preliminary peeling mechanism 700 performs the process (first process) shown in FIGS. 7 (a) to 7 (d), the process (second process) shown in FIG. 7 (e) is performed. As a result, the first cover lay film piece Wc1 is preliminarily peeled from the front end E1 to the winding end position P1, and the first cover lay film piece Wc1 has no pre-peeling region and non-peeling region. There is a pre-exfoliation area.

FIG. 8 is a diagram showing the first coverlay film piece Wc1 that has been subjected to preliminary peeling. In FIG. 8, the area shown in gray is the preliminary peeling area. That is, by performing the first step and the second step as shown in FIGS. 7 (a) to 7 (e), the first coverlay film piece Wc1 has a front end as shown in FIG. There is a preliminary peeling area corresponding to the winding length L from the part E1 to the winding end position P1, and a non-preliminary peeling area corresponding to the non-winding length ΔL from the winding end position P1 to the rear end E2. Exists.

As described above, the first coverlay film piece Wc1 after the preliminary peeling has a non-preliminary peeling area, and thus the first coverlay film piece Wc1 is peeled off from the mount Wm. Can be prevented. For this reason, the movable peeling unit 200 to be performed later does not hinder the process of peeling the first coverlay film piece Wc1. The winding end position P1 is preferably set to a position immediately before the rear end E2 of the first coverlay film piece Wc1.

By setting the winding end position P1 in this way, the preliminary peeling roll 710 preliminarily peels most of the first coverlay film piece Wc1, and the non-preliminary peeling area can be further reduced. Thereby, in the process which actually peels the 1st coverlay film piece Wc1 from the mount Wm, the 1st coverlay film piece Wc1 can be reliably peeled from the mount Wm with a smaller force.

In addition, in FIG. 8, although the 1st coverlay film piece Wc1 is demonstrated, each subsequent coverlay film piece of 2nd coverlay film piece Wc2, 3rd coverlay film piece Wc3, ... is followed. The same applies to (not shown in FIG. 8).

By the way, the diameter of the preliminary peeling roll 710 is not particularly limited. However, in the film peeling apparatus 1000 according to the first embodiment, the circumference of the preliminary peeling roll 710 is equal to or equal to the winding length L2. It is preferable to set the length to be slightly larger than the take-off length L2.

By setting the diameter of the preliminary peeling roll 710 in this way, when the preliminary peeling roll 710 performs an operation of winding the cover lay film piece (in this case, the first cover lay film piece Wc1) to be preliminary peeled, The first coverlay film piece Wc1 can be wound up before the preliminary peeling roll 710 finishes one rotation. Thereby, winding of a film can be performed efficiently.

In addition, since the film can be wound before the preliminary peeling roll 710 completes one rotation, when the preliminary peeling roll 710 performs the operation of winding the film, the surface of the preliminary peeling roll 710 is the first surface. Since it always contacts the surface of the cover lay film piece Wc1, the dust adhering to the surface of the first cover lay film piece Wc1 can be attached to the preliminary peeling roll 710 side. Thereby, according to the preliminary peeling roll 710 of such a structure, the effect of cleaning the surface of a film is also acquired.

When the preliminary peeling operation as shown in FIG. 7 is performed, this time, the movable peeling unit 200 performs the main peeling operation of the first coverlay film piece Wc1 from the mount. This peeling operation is the operation after FIG. That is, after the preliminary peeling roll 710 is lifted as shown in FIG. 7 (a) from the state where the preliminary peeling operation on the first coverlay film piece Wc1 is completed (the state shown in FIG. 7 (e)), it is movable. The main peeling operation by the peeling unit 200 is performed.

When performing this peeling operation, the movable peeling unit 200 travels to the front side of the traveling path, and the first coverlay film piece Wc1 that has been preliminarily peeled is directly below the suction holding device 800 (see FIG. 5B). .)

In this state, the suction holding device 800 is lowered to suck the first cover lay film piece Wc1 that has been preliminarily peeled (see FIG. 5C). At this time, the suction holding device 800 holds the suction state while being lowered. Here, the state of each clamping device is switched. That is, the first clamp device 500 is changed from “open” to “closed”, and the second clamp device 240 and the third clamp device 250 are both changed from “closed” to “open”.

And as shown to Fig.6 (a), the movable peeling unit 200 is made to drive | work to a traveling path back side (arrow x 'direction). When the movable peeling unit 200 is caused to travel rearward (in the direction of the arrow x ′), a force that resists traveling of the movable peeling unit 200 toward the rearward of the traveling path is applied to the mount Wm, and With the one coverlay film piece Wc1 held by the suction holding device 800, the movable peeling unit 200 is caused to travel to the rear side of the traveling path (in the direction of the arrow x ′). Thereby, the 1st coverlay film piece Wc1 adsorbed by the adsorption holding device 800 can be peeled off from the mount Wm.

As a means for giving the mount Wm a force that resists traveling of the movable peeling unit 200 to the rear side of the travel path, the mount Wm is taken up by the take-up reel 921 while moving the movable peeling unit 200 to the rear side of the travel path. It can be exemplified that winding is performed.

Such a main peeling operation can be surely performed by the presence of the peeling portion 230 provided at the tip of the movable peeling unit 200. That is, since the peeling unit 230 has a configuration as shown in FIG. 4, the movable peeling unit 200 travels to the rear side of the traveling path in a state where the first cover lay film piece Wc1 is sucked and held by the suction holding device 800. When the mount Wm is taken up by the take-up reel 921, the mount Wm is pulled in a state of being folded back by the mount folding portion 233 of the peeling unit 230. Accordingly, the mount Wm operates so as to be peeled off from the first coverlay film piece Wc1. Thereby, the 1st coverlay film piece Wc1 can be reliably peeled from the mount Wm.

By the way, when performing the main peeling operation as described above, if the preliminary peeling by the preliminary peeling roll 710 is not performed, the stress when the mount Wm is about to peel from the first coverlay film piece Wc1 is the first. In addition to the 1 coverlay film, wrinkles may occur in the first coverlay film piece Wc1, and the quality of the first coverlay film piece Wc1 may be deteriorated.

On the other hand, according to the film peeling apparatus 1000 according to the first embodiment, most of the region (see FIG. 8) of the first coverlay film piece Wc1 was once peeled from the mount Wm by the preliminary peeling roll 710. Since it is in a state, the adhesive force with the mount Wm is almost released. For this reason, when the backing paper Wm is peeled from the first cover lay film piece Wc1, the stress applied to the first cover lay film piece Wc1 is almost negligible. Thereby, it can prevent reliably that a wrinkle may arise in the 1st coverlay film piece Wc1 at the time of this peeling, and quality degradation of the 1st coverlay film piece can be prevented beforehand. Can be prevented.

In addition, in the state where the first cover lay film piece Wc1 is peeled off from the mount Wm, the support pedestal portion 270 of the movable peeling unit 200 has traveled to just below the suction holding device 800. For this reason, the support pedestal portion 270 is in a state of supporting the first cover lay film piece Wc1 sucked and held by the suction holding device 800 from the lower side (see FIG. 6A).

Then, the suction holding device 800 rises from the state of FIG. 6A (see FIG. 6B). As described above, the suction holding device 800 is orthogonal to the traveling path A after the first cover lay film piece Wc1 that has been peeled off from the mount Wm is sucked and lifted (see FIG. 6B). The first cover lay film piece Wc1 is temporarily bonded to a predetermined position of the base film by being transferred to a position just above the base film (not shown) along a traverse line (not shown).

At this time, the first cover lay film piece Wc1 is sucked and held by the suction holding device 800 in a state where the lower surface side is the sticking surface. For this reason, when temporarily pressure-bonded to the base film, the suction holding device 800 may lower the first cover lay film piece Wc1 held by suction as it is along the direction of gravity. Thereby, the 1st coverlay film piece Wc1 can be temporarily crimped | bonded to a base film appropriately in the stable state. Then, after the first coverlay film piece Wc1 is temporarily pressure-bonded to the base film, the suction holding device 800 returns to the original position (position shown in FIG. 6B) along the traverse line.

By the way, in the state where the suction holding device 800 is raised (see FIG. 6B), the state of each clamp device is switched, and the first clamp device 500 is changed from “closed” to “open”, and the second clamp device. Both 240 and the third clamping device 250 are changed from “open” to “closed”, and the cutting mechanism portion 600 is lowered again to perform the next cutting operation (see FIG. 6C).

The state of FIG. 6C is the same as the state of FIG. 5A, but in FIG. 6C, the cutting mechanism portion 600 causes the next cover lay film piece Wc2 (second cover lay film piece). A cutting operation for generating Wc2) is performed. The second coverlay film piece Wc2 is a coverlay film piece to be preliminarily peeled at the present time. At this time, the front side end portion of the second coverlay film piece Wc2 is a cut portion E2 (see FIGS. 7 and 8) when the first coverlay film piece Wc1 is generated, and the second coverlay film piece. The front side end of the piece Wc2 is located at the tip of the peeling portion 230 in the movable peeling unit 200. Then, the preliminary peeling operation as shown in FIGS. 7A to 7E is also performed on the second coverlay film piece Wc2. Thereafter, the main peeling operation shown in FIGS. 5B, 5C and 6A to 6C is performed.

By repeating such an operation, each coverlay film piece generated by the cutting operation of the cutting mechanism unit 600 is subjected to a preliminary peeling operation by the preliminary peeling roll 710, and as shown in FIG. In the coverlay film piece, most of the individual coverlay film pieces, with the non-preliminary peeling area slightly left, are the preliminary peeling area. Therefore, the main peeling operation shown in FIGS. 5B to 6B can be performed reliably and easily. As a result, when the cover lay film is peeled off from the mount, there is a problem that the cover lay film cannot be properly peeled off from the mount Wm depending on the material of the cover lay film, the material of the mount, and the kind of the adhesive. It can be prevented from occurring.

[Embodiment 2]
FIG. 9 is a front view of the film peeling apparatus 2000 according to the second embodiment.
FIG. 10 is a plan view of a film peeling apparatus 2000 according to the second embodiment. In FIG. 10, the delivery mechanism 910 and the take-up mechanism 920 shown in FIG. 9 are not shown.

The film peeling apparatus 2000 according to the second embodiment is different from the film peeling apparatus 1000 according to the first embodiment in that the front side end portion (also referred to as a front end portion) of each coverlay film piece is used as the coverlay film piece. This is that a preliminary peeling mechanism 660 is provided for preliminary peeling by a predetermined amount from the front side end portion toward the rear side end portion. In addition, since the preliminary | backup peeling mechanism part 660 is what peels the front side edge part, ie, front-end | tip part, of each coverlay film piece, it is called the front-end | tip preliminary | backup peeling mechanism part 660. In the film peeling apparatus 2000 according to the second embodiment, it is assumed that the film is a coverlay film.

In the film peeling apparatus 2000 according to Embodiment 2, the tip preliminary peeling mechanism 660 is provided in the cutting mechanism 600. In addition, in the film peeling apparatus 2000 which concerns on Embodiment 2 shown in FIG. 10, the same code | symbol is attached | subjected to the same component as the film peeling apparatus 1000 which concerns on Embodiment 1. FIG.

The tip preliminary peeling mechanism 660 is provided along the cutting blade 640 on the rear side of the traveling path from the cutting blade 640. The tip preliminary peeling mechanism 660 includes a plurality (four) of negative pressure suction ports 661 to 664 provided along the cutting blade 640 and air connected to the negative pressure suction ports 661 to 664. A suction pipe (not shown) and a negative pressure generator (not shown) are included.

The tip preliminary peeling mechanism 660 is configured so that when the coverlay film Wc with a mount that exists on the front side of the traveling path from the cutting blade 640 is cut by the cutting blade 640, the coverlay that exists on the rear side of the traveling path from the cutting blade 640. By sucking the leading end of the film Wc along the cutting line of the cutting blade 640, the leading end of the cover lay film Wc is preliminarily peeled from the mount Wm.

FIG. 11 is a diagram schematically showing a cutting operation by the cutting mechanism unit 600 and a preliminary peeling operation of the tip portion of the coverlay film piece by the tip preliminary peeling mechanism unit 660. FIG. 11 shows an enlarged main part of the cutting mechanism 600 in FIG. 11A shows a state before the cutting operation by the cutting mechanism unit 600, FIG. 11B shows a state in which the cutting operation by the cutting mechanism unit 600 is performed, and FIG. 11C shows the cutting operation. FIG. 11D shows a state where the cutting mechanism portion 600 is going to rise and return to the original position, and FIG. 11D shows the coverlay film Wc in which the leading edge preliminary peeling mechanism portion 660 has been subjected to preliminary peeling. Is shown. In addition, in Fig.11 (a), FIG.11 (b), and FIG.11 (c), the enlarged view of the circle | round | yen R enclosed with the broken line is each shown.

In FIG. 11, one piece of the cover lay film piece that has already been cut and is located on the front side of the traveling path with respect to the cutting mechanism portion 600 is referred to as a first cover lay film piece Wc1, and is subsequent to the first cover lay film piece Wc1. The coverlay film to be performed is referred to as a subsequent coverlay film Wc.

First, as shown in FIG. 11A to FIG. 11B, the cutting mechanism 600 is lowered in the direction of the arrow z ′, and the cover lay film Wc is cut by the cutting blade 640, whereby the first cover A lay film piece Wc1 is generated. At this time, the negative pressure suction ports 661 to 664 of the leading edge preliminary peeling mechanism 660 are in a state of sucking the leading edge of the subsequent cover lay film Wc.

Then, when the cutting operation is finished and the cutting mechanism unit 600 tries to rise to the original position (raised in the direction of the arrow z), the leading edge preliminary peeling mechanism unit 660 holds the suction operation, so that the subsequent cover lay film Wc The tip is peeled from the mount Wm (see FIG. 11C). And when the cutting mechanism part 600 will be in the state raised to the original position, the suction operation by the front-end | tip preliminary peeling mechanism part 660 will also be cancelled | released. When the suction operation is released, the leading end portion of the subsequent cover lay film Wc is in a state of being attached again to the mount Wm.

FIG. 11 (d) shows the subsequent cover lay film Wc whose tip has been pre-peeled by the tip pre-peeling mechanism 660, and the pre-peeled region is shown in gray. As shown in FIG. 11 (d), the trailing cover lay film Wc is in a state in which the tip is preliminarily peeled off.

In this way, after the leading edge of the subsequent cover lay film Wc is preliminarily peeled off, the cover lay film with mount Wc travels forward by a predetermined amount, and the cutting mechanism section 600 cuts the cover lay film with mount. Then, the subsequent cover lay film Wc from which the tip portion is preliminarily peeled becomes the second cover lay film piece Wc2. Since the tip of the second coverlay film piece Wc2 is preliminarily peeled as shown in FIG. 11D, the preliminary peeling operation by the preliminary peeling roll 710 performed thereafter is easy.

That is, as described with reference to FIGS. 7A to 7C, the preliminary peeling roll 710 is the coverlay film piece that is currently subject to preliminary peeling (in this case, the second coverlay film piece Wc2). When the operation of winding up the second coverlay film piece Wc2 is started from the state in contact with the front end E2 on the surface of the front surface, the front end E2 of the second coverlay film piece Wc2 is preliminarily peeled off. Therefore, the preliminary peeling roll 710 can easily take up the second coverlay film piece Wc2. Thereby, the preliminary peeling by the preliminary peeling roll 710 becomes more reliable.

Thus, according to the film peeling apparatus 2000 according to the second embodiment, the preliminary peeling operation by the preliminary peeling roll 710 can be more reliably performed. Thereby, the main peeling operation by the movable peeling unit 200 can be performed more reliably. In the film peeling apparatus 2000 according to the second embodiment, the first coverlay film piece Wc1 is not preliminarily peeled off at the front end portion. For example, the front side of the coverlay film actually used is used. By providing a dummy film on the front end, it is possible to perform preliminary peeling of the front end portion of the first coverlay film piece Wc1.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention. For example, the following modifications are possible.

(1) In each of the above embodiments, the case where the coverlay film Wc with mount is cut with the cutting mechanism 600 leaving the mount Wm is cut, but the coverlay film Wc is cut in advance with the mount Wm left. A coverlay film with a mount (referred to as a coverlay film with a precut mount) can also be used.

As described above, when the pre-cut cover-attached cover lay film is used in the film peeling apparatus 1000 according to the first embodiment or the film peeling apparatus 2000 according to the second embodiment, the cutting mechanism unit 600 does not perform the cutting operation. You should set it like this.

Alternatively, a film peeling device dedicated to a coverlay film with a pre-cut mount may be used. As a film peeling device dedicated to a coverlay film with a pre-cut mount, for example, in the film peeling device 1000 according to the first embodiment or the film peeling device 2000 shown in the second embodiment, a film having no cutting mechanism is peeled off. An apparatus can be illustrated. In addition, even if it is a film peeling apparatus which does not have the cutting | disconnection mechanism part 600, you may make it provide the front-end | tip preliminary | backup peeling mechanism part which carries out preliminary peeling of the front side edge part (tip part) of each coverlay film piece. As this tip preliminary peeling mechanism part, the thing substantially the same as the tip preliminary peeling mechanism part 660 demonstrated in the film peeling apparatus which concerns on Embodiment 2 can be used.

(2) In each of the above embodiments, the preliminary peeling roll 710 is exemplified as having the adhesive force on the entire surface, but the entire surface may not necessarily have the adhesive force.

FIG. 12 is a view for explaining a modified example of the preliminary peeling roll 710. 12A is a diagram showing a first modification of the preliminary peeling roll 710, FIG. 12B is a diagram showing a second modification of the preliminary peeling roll 710, and FIG. 12C is a preliminary peeling.

This is a case where, in addition to the belt-like adhesive portion 713, a belt-like adhesive portion 713 that makes one round in the circumferential direction is formed also in the central portion in the width direction.

In such a preliminary peeling roll 710D, when the preliminary peeling roll 710C is lowered, the adhesive portions 713 provided at three locations are located at both ends and the center in the width direction on the surface of the first coverlay film piece Wc1. After contacting each other, the same operation as described in the first embodiment can be performed. In addition, in FIG.12 (d), although the case where the circumferential direction adhesion part 713 was each formed in three places of the width direction both ends and center part in the surface of preliminary | backup peeling roll 710D was illustrated, it is restricted to three places. It is good also as four or more places instead of things.

In addition, in the 3rd modification and the 4th modification, although the case where each adhesion part 713 was formed so that it might continue in the circumferential direction was illustrated, you may form in the state intermittent in the circumferential direction.

Further, the present invention is not limited to these modified examples, and for example, a combination of FIGS. 12 (a) to 12 (d) may be used, and the surface of the preliminary peeling roll 710 may be adhered in a mosaic shape. A part may be formed.

(3) In each of the above embodiments, the case where the preliminary peeling roll 710 has an adhesive portion on the surface and the preliminary peeling is performed by the adhesive force by the adhesive portion has been described. However, the preliminary peeling roll 710 is sucked by negative pressure. It may be a preliminary peeling roll that performs preliminary peeling by force. In addition, the preliminary | backup peeling roll which performs preliminary | backup peeling with the suction force by a negative pressure is called "suction type preliminary | backup peeling roll."

FIG. 13 is a view for explaining the suction type preliminary peeling roll. FIG. 13A is a view showing a first example of a suction type preliminary peeling roll (hereinafter referred to as a first suction type preliminary peeling roll 710E), and FIG. 13B is a drawing of the suction type preliminary peeling roll. It is a figure which shows the figure which shows the 2nd example (henceforth the 2nd suction-type preliminary | backup peeling roll 710F).

The first suction-type preliminary peeling roll 710E and the second suction-type preliminary peeling roll 710F have a cylindrical shape having a space inside, and as shown in FIGS. 13 (a) and 13 (b), the first suction-type preliminary peeling roll 710F.

It is preferable that the circumference of the type preliminarily separating roll 710E or the second suction type preliminarily separating roll 710F is set to be equal to or slightly larger than the winding length L2 (see FIG. 8). .

By setting the diameters of the first suction type preliminary peeling roll 710E or the second suction type preliminary peeling roll 710F in this way, the first suction type preliminary peeling roll 710E or the second suction type preliminary peeling roll 710F is When performing the operation of winding the coverlay film (for example, the first coverlay film piece Wc1) to be preliminarily peeled, the first suction-type preliminarily peeling roll 710E or the second suction-type preliminarily peeling roll 710F finishes one rotation. The coverlay film can be wound up before. Thereby, winding of a film can be performed efficiently.

Further, as the preliminary peeling roll, in addition to the preliminary peeling roll that preliminarily peels off by adhesive force and the preliminary peeling roll that preliminarily peels off by suction force due to negative pressure, a preliminary peeling roll that preliminarily peels off by electrostatic attraction force is used. It is also possible.

(4) In each of the above embodiments, when the preliminary peeling is performed by the preliminary peeling roll 710, the side of the coverlay film Wc with mount is reciprocated along the traveling path so that the preliminary peeling roll 710 is covered with the coverlay. Although the case where preliminary peeling is performed by rotating on a film (for example, the first coverlay film piece Wc1) is illustrated, the preliminary peeling is performed by reciprocating the side of the preliminary peeling roll 710 along the traveling path. It can also be done.

Further, both the coverlay film Wc with mount and the preliminary peeling roll 710 may be reciprocated. In this case, the traveling direction of the coverlay film Wc with mount and the traveling direction of the preliminary peeling roll 710 are opposite to each other. Thereby, the preliminary peeling operation can be further speeded up.

(5) After the preliminary peeling by the preliminary peeling roll 710 is completed, the movable peeling unit shown in each of the above embodiments is used as a mechanism for peeling the coverlay film (for example, the first coverlay film piece Wc1) from the mount Wm. Although the case where 200 was used was illustrated, it is not restricted to this, A various peeling mechanism can be used.

(6) In each of the above embodiments, the preliminary peeling operation by the preliminary peeling roll 710 is performed by a mechanism for cutting a long coverlay film with a mount in a roll-to-roll film peeling apparatus. Exemplified the case where the cover lay film piece generated by being cut in a state in which the mount is left is peeled off from the mount, but is not limited to this. The present invention can also be applied to the case where the cover lay film of the cover lay film with mount is peeled off from the mount.

As described above in the first or second embodiment, even in the case of the short coverlay film with a mount that is individual for each sheet, the preliminary peeling mechanism unit 700 performs the first step and the first step shown in FIG. By performing two steps, the coverlay film in the coverlay film with the short mount can be preliminarily peeled from the mount.

(7) In the above embodiments, the film is described as being a coverlay film, but is not limited to a coverlay film, and may be, for example, a reinforcing film. Alternatively, it may be a film for a touch panel that is attached to a display portion of an electronic device (for example, a liquid crystal display panel, an organic EL display panel, etc.) and used to input information to the electric device. Furthermore, it may be a protective film or other film for protecting the panel surface of a display unit (for example, a liquid crystal display panel, an organic EL display panel, etc.) of an electronic device.

(8) In the second embodiment, the case where the leading edge of the coverlay film is preliminarily peeled by the leading edge preliminary peeling mechanism 660 is illustrated in the stage before the preliminary peeling operation by the preliminary peeling roll 710. Other preliminary peeling mechanisms may be used in combination. For example, a preliminary peeling mechanism unit (preliminary peeling mechanism unit 400 in FIG. 14) provided in a film peeling apparatus 9000 (see FIG. 14) disclosed in Patent Document 1 is provided, and the preliminary peeling mechanism unit 400 is provided. After preliminary peeling of both sides of the coverlay film Wc with the first peeling plate 410 and the second peeling plate 420, the leading edge preliminary peeling mechanism 660 performs preliminary peeling, and then the preliminary peeling roll 710. You may make it perform the preliminary | backup peeling operation | movement by. By doing in this way, this peeling operation by the movable peeling unit 200 can be made more reliable.

In this case, however, the auxiliary roll removes dust attached to the preliminary peeling roll 710. (Not shown) can be provided so as to be in contact with the preliminary peeling roll 710. Since the auxiliary roll is for removing dust adhering to the preliminary peeling roll 710, the auxiliary roll is preferably formed of a member having a higher adhesive strength than the preliminary peeling roll 710.

As such an auxiliary roll, for example, an adhesive tape wound in a roll shape can be preferably used. By providing such an auxiliary roll so as to be in contact with the preliminary peeling roll 710, the dust attached to the preliminary peeling roll 710 can be adhered to the auxiliary roll side to some extent. Thereby, the preliminary peeling roll 710 can be used for a long time, and the maintenance of the preliminary peeling roll 710 can be made easy.
Further, the auxiliary roll is not formed by winding an adhesive tape, and the auxiliary roll itself may be a member having adhesive force.

(10) In each of the embodiments described above, the preliminary peeling roll 710 has been described as a member having an adhesive force as a whole. However, the invention is not limited to this, and only the surface of the preliminary peeling roll 710 has an adhesive force. You may have. For example, a member having adhesive force may be wound around the surface of a cylindrical body from a synthetic resin or the like, or an adhesive layer may be formed on the surface of the cylindrical body.
