Plastic film peeling device

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a peeling device for a plastic film, and more particularly to a cover film for peeling off a side of a strip-shaped backing film by a cover film. A peeling device for a plastic film of a plastic film such as a film).

Generally, a flexible wiring substrate is produced by using a thin polyimide film or a polyester film as a base film, and a surface is attached to the surface of the flexible film. Copper foil for the circuit. Moreover, electronic components are directly mounted on the electronic circuit, and the electronic circuit is covered with a cover film.

Further, such a flexible wiring board is characterized in that it is thin and flexible and can be bent freely. However, when a component is mounted thereon or connected to a connector, a certain thickness and hardness are required. Therefore, in order to secure the rigidity of a part of the base film, a reinforcing plate having a predetermined shape and size is attached to the base film.

In the manufacturing process of the above-mentioned flexible wiring substrate, the process of attaching the front stage of the cover film on the electronic circuit to be covered on the base film is firstly required to be pre-cut by the hand-off film by manual work. (pre-cutting) cover film. Further, in the case of the reinforced film, it is also necessary to manually peel off the reinforced film from the lining film.

Such a manual peeling of the cover film or the reinforcing film by the mating film Wm (described below only for the cover film) has become a major obstacle to automation in manufacturing the flexible wiring board. Further, when the cover film is peeled off from the lining film, if the cover film is to be pulled up perpendicularly to the surface of the lining film, a large peeling force is required. For example, there is a peeling device for a plastic film disclosed in Patent Document 1 (hereinafter referred to as a conventional peeling device for a plastic film).

Fig. 13 is a view showing the configuration of a conventional peeling device for a plastic film. As shown in FIG. 13, the conventional peeling device for a plastic film is provided with a base table 1 having a substantially horizontal guide surface at an upper end portion, and a guide surface along the base table 1 a movable peeling unit 5 that reciprocates between the front and rear (arrows x-x' direction) and is provided with a peeling portion 9 at the top end; a driving device for reciprocatingly driving the movable peeling unit 5 (by a ball screw ( Ball screw), a servo motor 8 or the like; an adsorption holding device that is detachably attached to the lining film Wm and pre-cut into a plastic film of a predetermined size (as a cover film Wc) 35; a clamping apparatus 45 disposed on the side of the base table 1 to sandwich the cover film Wc attached to the mating film Wm; disposed on the side of the movable peeling unit 5, capable of sandwiching the peeling cover film Wc A clamping device 50 for the membrane Wm. Further, the cover film Wc attached to the state of the lining film Wm is also a cover film Wc with a lining film attached thereto.

[Patent Document 1] International Publication No. WO2009/075030

According to the conventional peeling device for a plastic film, the movable peeling unit 5 is moved in the x direction in a state where the coating film Wc with the lining film is held by the adsorption holding device 35, and the movable peeling unit 5 is moved. Since the peeling portion 9 peels the pre-cut cover film Wc from the lining film Wm at an acute angle of separation, it is possible to obtain an excellent effect of smoothly peeling the cover film Wc from the lining film Wm with a small force.

However, in the conventional peeling device for a plastic film, there is a possibility that the adhesion force between the cover film Wc and the backing film Wm is large, or the material of the cover film Wc and the material of the backing film Wm are attached. The cover film Wc cannot be appropriately peeled off by the lining film Wm depending on the type of the attached agent or the like.

Moreover, the conventional peeling device for a plastic film is adsorbed and held by the adsorption holding device 35 in a state where the cover film Wc is on the lower side of the lining film Wm. Therefore, the cover film Wc peeled off by the mating film Wm is in a state in which the attaching surface faces upward, and in this state, it is transferred to the base film along the traverse line by a sliding table 34 (not shown). Immediately below the display, it is temporarily pressed to a predetermined position of the base film.

As described above, in the conventional plastic film peeling apparatus, when the cover film Wc which is peeled off by the mating film Wm is temporarily pressed against the base film, the base film exists on the upper side, and the cover film Wc which is temporarily crimped becomes the lower side, and the back gravity is reversed. The direction of the cover film Wc is temporarily crimped to the base film. Of course, this configuration is also preferable. On the contrary, the base film of the temporary crimping end exists on the lower side, and the cover film Wc which is temporarily crimped becomes the upper side, and the cover film Wc is temporarily crimped to the base film in the direction of gravity. There is also a better case for automating the manufacture of a flexible wiring board.

Here, in order to be temporarily pressed, the cover film Wc is on the upper side, in gravity In the direction in which the cover film Wc is temporarily crimped to the base film, it is preferable to move the base table 1 in a state where the cover film Wc is on the upper side of the lining film Wm, and the cover film is adsorbed by the upper side by the adsorption holding device 35. Wc. In other words, in this case, the cover film Wc of the peeling film Wm is adsorbed and held by the adsorption holding device 35 in a state where the attaching surface faces downward, and is transferred to the base film (not shown) in this state. Directly above, the cover film Wc is lowered in the direction of gravity of the base film and is temporarily crimped.

However, with this configuration, since the adsorption operation by the adsorption holding device 35 is reversed in the direction of gravity, the adsorption retention of the cover film Wc may become unstable. Therefore, when the cover film Wc is peeled off by the lining film Wm in a state where the cover film Wc is adsorbed and held by the adsorption holding device 35, the adhesion force between the cover film Wc and the lining film Wm is large as described above. There is also a possibility that the cover film Wc cannot be appropriately peeled off by the mating film Wm.

Accordingly, it is an object of the present invention to provide a peeling device capable of peeling a plastic film of a plastic film from a lining film with a small force.

[1] The peeling device for a plastic film according to the present invention, in the process of walking the plastic film with the lining film along a guide in a state where the lining film is on the lower side, the plastic film with the lining film The film-based plastic film is detachably attached to the lining film, and includes: a base table having a slightly horizontal guiding surface formed on the lower side of the guiding path along the guiding path; and having a peeling off from the lining film The peeling portion of the plastic film may be a movable peeling unit that reciprocates in a predetermined range along a front side of the guide path and a rear side of the guide path along the guide surface of the base table; The aforementioned guide The cutting blade in the direction cuts the plastic film while leaving the lining film, and generates a cutting mechanism portion of the plastic film having a predetermined size along the direction of the guide path; and detachably holds the plastic film A holding device for holding a plastic film, wherein the peeling portion has a plane that supports the lining film along a bottom surface of the lining film, and a lining film that is folded over 90 degrees in a state in which the lining film is in contact with the plane In the folding portion, the movable peeling unit further includes: a steering roller that changes a traveling direction by folding the folding film of the backing film by 90 degrees or more and moves the horizontal direction; and the guide is disposed in the peeling portion When the plastic film with the lining film is cut off, the cutting support base portion of the plastic film with the lining film is supported by the lower side, and the movable peeling unit is moved toward the rear side of the guide path.

Wc2. Further, in FIGS. 7(a), 7(b) and 7(c), an enlarged view of a circle R surrounded by a broken line is shown.

Further, in FIG. 7, it is intended that the cover film Wc which has been cut and located on the front side of the guide path portion 600 is also the first The cover film Wc1 is said to be followed by the cover film Wc with the backing film of the first cover film Wc1 as the subsequent cover film Wc.

First, as shown in Fig. 7(a), the cutting mechanism portion 600 is located above the cover film Wc with the lining film attached thereto, and as shown in Fig. 7(b), the cutting mechanism portion 600 is lowered in the direction of the arrow z'. The first cover film Wc1 is produced by cutting the cover film Wc with the lining film by the cutting blade 640. Then, at this time, the negative pressure suction ports 661 to 664 of the second preliminary peeling mechanism unit 660 are in a state of attracting the distal end portion of the subsequent cover film Wc.

Then, when the cutting operation is completed and the cutting mechanism portion is raised to the original position (increased in the direction of the arrow z), the second preliminary peeling mechanism portion 660 holds the suction operation, so that the tip end of the subsequent cover film Wc is covered by the lining film Wm. Peeling (refer to Fig. 7 (c)). Then, as soon as the cutting mechanism unit 600 is raised to the original position, the suction operation by the second preliminary peeling mechanism unit 660 is released. When the suction operation is released, the tip end portion of the subsequent cover film Wc is brought into contact with the lining film Wm again, and since it is peeled off in a single state, the adsorption holding device 700 and the movable peeling unit 200 are performed later. The actual peeling action becomes easy.

Fig. 7 (d) is a view showing a cover film Wc2 for performing preliminary peeling of the distal end portion by the second preliminary peeling mechanism portion 660, and shows a region to be peeled off in gray. As shown in Fig. 7 (d), the cover film Wc2 in which the preliminary peeling of the distal end portion is performed is a state in which the distal end portion (the region indicated by the symbol S) is also preliminarily peeled off except for the both side portions.

FIG. 8 is a view showing a plurality of negative pressure adsorption ports 711 disposed on the lower end surface of the adsorption plate 710. The negative pressure adsorption port 711 is as shown in FIG. The lower end surface of the 710 is provided with a plurality of mesh shapes. Further, on the lower end surface of the adsorption plate 710, a screw hole 712 for making the attachment of the adsorption region setting plate 750 (see FIG. 9) for setting the size of the adsorption region is provided, for example, at four places.

9(a), (b), and (c) are diagrams for explaining setting examples of the size of the adsorption region of the adsorption plate 710. Fig. 9(a) shows a case where the approximate entire area of the lower end surface of the adsorption plate 710 is regarded as a negative pressure suction region, and this case is the same state as Fig. 8. Further, FIG. 9(b) is a view showing an example of the adsorption region setting plate 750, and the adsorption region setting plate 750 is provided with an opening portion 751. Further, the adsorption region setting plate 750 is provided with a screw hole 752 which is provided in correspondence with the screw hole 712 provided in the adsorption plate 710, and can be attached to the adsorption plate 710 by screws.

Fig. 9 (c) is a view showing a state in which the adsorption region setting plate 750 of Fig. 9 (b) is attached to the adsorption plate 710 of Fig. 9 (a). The adsorption region setting plate 750 shown in FIG. 9(b) has an opening portion having a length L in the direction along the guide path A. Therefore, by installing such an adsorption region setting plate 750, only the region of the length L can be set as the negative pressure adsorption region in the traveling direction in the guide path A.

Such an adsorption region setting plate 750 can be prepared in various ways in accordance with what size the cover film Wc is attached to. Further, the size of the guide film direction of the one piece of the cover film cut by the cutting mechanism unit 600 is hereinafter referred to as the cover film size.

For example, the peeling device 1000 for a plastic film according to the first embodiment can produce a cover film having a cover film size of 10 mm to 350 mm, which is currently set to produce a cover film having a cover film size of 100 mm. In the case, the adsorption region setting plate 750 corresponding to the cover film size of 100 mm is attached to the adsorption plate 710. According to this, in the case where the size of the cover film is short, even in the case where the cut cover film is continuously conveyed, the cover film which is cut can be appropriately adsorbed and held one by one.

Further, in the case of setting the cover film having a cover film size (350 mm or a cover film size of approximately 350 mm) having an upper limit which can be generated, the adsorption region setting plate 750 is not attached to perform the adsorption holding operation.

Next, an operation example of the peeling device 1000 for a plastic film according to the first embodiment will be described.

Figs. 10(a), (b) and (c) and Figs. 11(a), (b) and (c) are diagrams schematically showing an operation example of the peeling device 1000 for a plastic film according to the first embodiment. In addition, in FIG. 10 and FIG. 11, only the main components necessary for description of an operation program are shown, and it is simplified by FIG. 1 and FIG. Here, the same symbols are attached to the same constituent elements as those of FIGS. 1 and 2.

A guide film Wa having a predetermined length is connected to a distal end portion of the cover film Wc attached to the transport reel 810, and the distal end portion of the guide film Wa is pulled out by the transport reel 810 to the upper direction. The direction of the steering roller 830 is changed to the horizontal direction, the first preliminary peeling mechanism portion 400, the first clamping device 500 fixed to the base table 100, the second clamping device 240 fixed to the movable peeling unit 200, and cut. The breaking mechanism portion 600 is stretched by folding the gusset film folding portion 233 (see FIG. 6) of the peeling portion 230 by 90 degrees or more, and is then redirected by the steering drum 260 in the horizontal direction. Then, it is set, and the guide film Wa is converted into the lower direction by the direction of the steering drum 840, and is wound around the roll by the nip roller 850 (refer to FIG. 1). Winding reel 820.

Further, the cover film Wc with the lining film is initially set to, for example, the state in which the first peeling plate 410 and the second peeling plate 420 of the first preliminary peeling mechanism portion 400 are inserted between the lining film Wm and the cover film Wc by the operator. . Then, the tip end portion P0 of the cover film Wc with the gusset film is adjusted to the position of the gusset film folding portion 233 of the peeling portion 230 in the movable peeling unit 200 (see FIG. 10(a)).

In the state shown in Fig. 10 (a), the cutting operation is performed by the cutting mechanism unit 600, and the cover film Wc is cut. The cover film Wc (the cover film Wc on the front side of the guide path from the cutting edge 640) which is generated by the cutting operation here is the first cover film Wc1. When the cutting operation is performed, the second preliminary peeling mechanism portion 660 is preliminarily peeled off the subsequent cover film Wc, that is, the subsequent cover film Wc which should be the next cover film (set as the second cover film Wc2) Top part.

In the preliminary peeling operation of the distal end portion, the negative pressure suction ports 661 to 664 of the second preliminary peeling mechanism portion 660 are attracted to the distal end portion of the subsequent cover film Wc at the same time as the cutting operation by the cutting mechanism portion 600. This is performed by the cutting mechanism unit 600 rising. As a result, the tip end portion of the subsequent cover film Wc is peeled off by the mating film Wm (the state in which it is peeled off).

Further, the state of each of the clamping devices at this time is that the first clamping device 500 is in an unclamped state (the unclamped state is indicated as [ON]), and the second clamping device 240 and the third clamping device 250 are both It becomes the clamped state (mark the clamped state as [closed]).

And in this case, the size of a piece of cover film (cover film size) In the example of FIG. 10, the distance from the position of the slightly distal end portion of the peeling portion 230 to the cutting edge 640 is obtained. The size of the cover film can be arbitrarily set within a predetermined range (for example, in the range of 100 mm to 350 mm) by setting the amount of movement of the movable peeling unit 200. Further, the cover film size is represented by [L], and in this case, L = 100 mm is set.

Therefore, in this case, the adsorption region setting plate 750 having the opening portion corresponding to L = 100 mm is attached to the adsorption plate 710 of the adsorption holding device 700. Here, the length L of the opening portion of the adsorption region setting plate 750 does not need to be exactly L = 100 mm.

Then, when the cutting operation is completed, the movable peeling unit 200 is moved to the front side of the guide path (arrow x direction) as shown in FIG. 10(b) from the state of FIG. 10(a). The state of each of the clamp devices at this time is that the first clamp device 500 is [ON], and both the second clamp device 240 and the third clamp device 250 are [closed]. In this state, the respective clamping devices are moved by the movable peeling unit 200 from the state of FIG. 10(a) to the front side of the guide (arrow x direction), and only the moving backing film Wm is wound in the winding reel 820. The portion, and only the moving film portion affixed with the cover film Wc in the transport reel 810.

The movable peeling unit 200 moves in the direction of the arrow x, and once the cut first covering film Wc1 reaches the position opposed to the adsorption holding device 700 (see FIG. 10(b)), the adsorption holding device 700 descends and adsorbs the first The film Wc1 is covered (see Fig. 10(c)). At this time, the adsorption holding device 700 maintains the adsorption state under the lowering. Here, the state of each clamping device is switched. That is, the first clamping device 500 is [opened] into [closed], and both the second clamping device 240 and the third clamping device 250 are [closed] into [open].

Then, as shown in Fig. 11 (a), the movable peeling unit 200 is moved to the rear side of the guide path (arrow x' direction). Further, when the movable peeling unit 200 is moved to the rear side of the guide path (arrow x' direction), the lining film Wm is given a force against the rear side of the movable peeling unit 200 toward the guide path, and is borrowed in the first plastic film Wc1. The movable peeling unit 200 is moved to the rear side of the guide path (arrow x' direction) in a state of being held by the adsorption holding device 700. According to this, the first cover film Wc1 adsorbed to the adsorption holding device 700 can be peeled off by the lining film Wm.

Further, the means for giving the lining film Wm a force against the rear side of the movable path of the movable peeling unit 200 can be exemplified by winding the lining film Wm with the winding reel 820 while moving the movable peeling unit 200 to the rear side of the guide path. .

This peeling operation can be reliably performed by the presence of the peeling portion 230 disposed at the distal end portion of the movable peeling unit 200. In other words, the peeling portion 230 has a configuration as shown in FIG. 6, and the movable peeling unit 200 having the peeling portion 230 is moved to the rear side of the guide path, and the lining film Wm is wound around the winding drum 820. When the lining film Wm is folded by the reticle film folding part 233 of the peeling part 230, the tension is given to the lining film Wm while walking. This is an operation of peeling off the lining film Wm by the first cover film Wc1, and a large peeling force can be obtained with a small force, whereby the first cover film Wc1 can be surely peeled off by the lining film Wm.

In the state where the first cover film Wc1 is peeled off by the lining film Wm, the support pedestal portion 270 of the movable peeling unit 200 is moved to the state immediately below the adsorption holding device 700. Therefore, the support pedestal portion 270 The state in which the first cover film Wc1 of the adsorption holding device 700 is adsorbed and held by the lower side is supported (see FIG. 11( a )).

Then, in the state of Fig. 11 (a), the adsorption holding device 700 is raised (refer to Fig. 11 (b)). In this manner, the adsorption holding device 700 is in a state in which the first cover film Wc1 peeled off by the lining film Wm is sucked and raised (see FIG. 11(b)), and is then crossed along the guide line orthogonal to the guide path A (not shown). The first cover film Wc1 is temporarily pressed against a predetermined position of the base film by being transferred directly above the base film (not shown).

At this time, the first cover film Wc1 is adsorbed and held by the adsorption holding device 700 in a state in which the surface is adhered to the bottom surface side, and the adsorption holding device 700 is left intact in the gravity direction when temporarily pressed against the base film. Since the first cover film Wc1 that is adsorbed and held is lowered, the first cover film Wc1 can be temporarily pressure-bonded to the base film in a stable state. Then, after the first cover film Wc1 is temporarily pressed against the base film, the adsorption holding device 700 returns to the original position along the cross line (the position of FIG. 11(b)).

However, in a state in which the adsorption holding device 700 is raised (see FIG. 11(b)), the state of each of the clamp devices is switched, and the first clamp device 500 is [closed] into [open], and the second clamp device 240 and When the third clamp device 250 is [open] to [closed], the cutting mechanism portion 600 is lowered again and the next cutting operation is performed (see FIG. 11(c)).

The state of Fig. 11(c) is the same as that of Fig. 10(a), but in Fig. 11(c), the cutting mechanism portion 600 is used to generate the next cover film Wc2 (set as the second cover film). Wc2) cutting action. At this time, the cutting operation is performed by the cutting mechanism unit 600, and the second preliminary peeling mechanism is simultaneously The portion 660 is prepared to peel off the distal end portion of the subsequent cover film Wc, that is, the distal end portion of the subsequent cover film Wc to be the third cover film Wc3 (not shown). Then, the same operations as those of FIGS. 10(b) and 10(c) and FIGS. 11(a) and 11(b) are performed.

Further, the second cover film Wc2 generated by the cutting operation shown in FIG. 11(c) is preliminarily peeled off by the second preliminary peeling mechanism portion 660 on both side portions, and when the first cover film Wc1 is cut. The tip portion is preliminarily peeled off by the second preliminary peeling mechanism portion 660. Therefore, the peeling operation performed in FIG. 11(a) can be performed reliably and easily.

By repeating such an operation, each of the cover films generated by the cutting operation of the cutting mechanism unit 600 is preliminarily peeled off by the first preliminary peeling mechanism unit 400 on both side portions, and the tip portion is separated by the second preliminary peeling mechanism. The portion 660 is ready for peeling. Therefore, the peeling operation shown in FIG. 11(a) can be surely and easily performed, and it is possible to prevent the cover film from being peeled off by the lining film due to the state of the attaching force or the like.
