The present invention particularly relates to a peeling mechanism provided with cooling means and a laminating device using the peeling mechanism.

The laminating device stacks a plurality of sheets constituting an electronic component, and includes a peeling mechanism, an alignment means, a laminating means, a transporting means, and the like. This peeling mechanism peels the film from the uppermost sheet before the sheets are aligned by the alignment means or after the laminated body composed of a plurality of sheets is formed by the laminating means.

For example, in Patent Document 1 (particularly, see paragraphs [0052]-[0055] and FIG. 6A), there is a peeling mechanism (hereinafter referred to as "conventional peeling mechanism"), which covers the entire sheet with a film. On the other hand, it is described that the film is peeled off from the sheet after heat treatment is performed to reduce the adhesive force by the foaming expansion of the adhesive layer.

However, in the conventional peeling mechanism, since the sheet with the film is totally softened by the heat treatment, there is a problem that it is difficult to start the peeling of the film from the sheet, that is, to form the peeling starting point. (Hereinafter, it is said that it is difficult to form the peeling starting point).

Further, in recent years, since the laminated body has been required to be smaller and have a lower height, the laminated sheet itself has been thinned. The rigidity of this thinned sheet is relatively low. Therefore, when heat treatment is performed on the entire thinned film-attached sheet using the conventional peeling mechanism, the rigidity of the thinned sheet is further reduced, and the film and the sheet are integrated.

It is an object of the present invention to provide the laminating apparatus used.

The peeling mechanism of one embodiment according to the present invention includes a peeling stage on which a sheet with a film is placed in a fixed state, and a peeling head for peeling the film from the sheet placed on the peeling stage. The peeling head is a relative between the peeling head and the peeling stage while holding a part of the outer peripheral portion of the sheet with the film to form a peeling starting point and the film at the peeling starting point. It includes a film holding means for peeling the film from the sheet by movement.

First, in the peeling mechanism 100, one sheet Sf with a film is placed on the peeling stage 20 in a fixed state, and then a part of the outer peripheral portion of the film f is held by the peeling head 10. After that, the film f is peeled from the sheet S by the relative movement between the peeling head 10 (see FIG. 2A) and the peeling stage 20. In the peeling mechanism 100 of the present embodiment, unlike the conventional peeling mechanism, the entire sheet Sf with a film is not heat-treated, so that the softening of the sheet with a film can be suppressed as a whole. can.

When the peeling of the film f from the sheet S is completed in the peeling mechanism 100, the transport holding mechanism moves from the standby position (not shown) to the peeling stage position A by the transport slide mechanism, and then moves downward in the Z-axis direction. Moving. When this transport holding mechanism comes into contact with the sheet S, the sheet S is held by the transport holding mechanism by vacuum suction. After that, the transport holding mechanism moves upward in the Z-axis direction by the transport slide mechanism, moves from the peeling stage position A to the alignment stage position B, moves in the X-axis direction (arrow I direction), and then moves in the Z-axis direction. It moves downward and comes into contact with the upper surface of the alignment stage 201. Then, the transfer holding mechanism releases the suction holding, so that the sheet S is placed at a predetermined position on the alignment stage 201, and then the transfer holding mechanism moves to the standby position by the transfer slide mechanism.

Further, when the seat S is properly aligned in the alignment means 200, the transport holding mechanism moves downward from the standby position to the alignment stage position B by the transport slide mechanism and then moves downward in the Z-axis direction. .. Then, when the transport holding mechanism is brought into contact with the seat S that has been properly aligned on the alignment stage 201, the sheet S is held by the transport holding mechanism by vacuum suction. After that, the transport holding mechanism moves upward in the Z-axis direction by the transport slide mechanism, moves from the alignment stage position B to the stacking stage position C, moves in the X-axis direction (arrow II direction), and then moves in the Z-axis direction. Moves downward and comes into contact with the upper surface of the laminated stage 301 or another sheet S already laminated. Then, the transfer holding mechanism releases the suction holding, so that the sheet S is placed at a predetermined position on the laminated stage 301. By performing the laminating step in the laminating apparatus 1 described above, the film f is peeled off from the sheet S, and the sheet S that has been properly aligned is laminated to form a laminated body. As a result, the laminated body can be formed by using the sheet S in which the deterioration of quality is suppressed.

In the peeling mechanism 100 in the present embodiment, since the object to be peeled is a sheet Sf with a film, the alignment means 200 peels the film f from the sheet S before the sheet S is aligned. There is. However, the present invention is not limited to this, for example, if the object to be peeled off is the sheet Sf with a film on the uppermost layer of the laminated body, the laminated body composed of a plurality of sheets S is formed by the laminating means 300, and after temporary crimping, the laminated body is formed. The film f may be peeled off from the uppermost sheet S.

The stacking device 1 in the present embodiment includes a peeling mechanism 100, an alignment means 200, a stacking means 300, a transporting means, and a control means. However, the laminating device 1 in the present embodiment is not limited to this, and includes, for example, a sheet supplying means for supplying the sheet S onto the peeling stage 20, a crimping means for crimping and integrating the laminated body of the sheets S, and the like.

The adhesive roller 12 has a cylindrical shape and has an adhesive surface having an adhesive surface on the outer peripheral surface 12b. Although the details will be described later, the adhesive surface of the adhesive roller 12 can peel the film f from the sheet S and hold the peeled film f by adhering the film f. The outer peripheral surface 12b of the adhesive roller 12 in the present embodiment is entirely an adhesive surface, but the present invention is not limited to this, and at least a part (for example, a region where the film f adheres) may be an adhesive surface. Further, the material of the adhesive surface of the adhesive roller 12 in the present embodiment is composed of, for example, an adhesive such as a system, an acrylic system, or a silicon system.

The urging member 13 is composed of a spring or the like, has a rotation shaft 13a orthogonal to the diagonal direction L at the lower end portion and extends in the horizontal direction, and is supported in a state of hanging from the peeling head 10.

The adhesive roller 12 is rotatably supported with respect to the urging member 13 in the rotation direction (arrow VII direction) about the rotation shaft 13a. In the present embodiment, when the adhesive roller 12 is brought into contact with the film f, the adhesive roller 12 is adjusted by adjusting the pushing amount of the urging member 13 in the urging direction (arrow VI direction) by the peeling head driving means. Can be loaded on the film f with a desired urging force.

By this clamp claw drive mechanism, the clamp claw 14 is arranged close to the adhesive roller 12, and the film f can be sandwiched between the clamp claw 14 and the adhesive roller 12.

<About the peeling stage>
As shown in FIG. 2 (c), the peeling stage 20 has a plurality of suction plates 21 arranged on the peeling stage 20 and a plurality of sheets Sf with a film, which is a peeling target, vacuum-sucked via the suction plate 21. A suction port 22 is provided.

The suction plate 21 has a plurality of communication holes in order to prevent the sheet S from being damaged. For example, the suction plate 21 may be composed of a plate-shaped member having a plurality of holes, or may be made of a resinous porous material. It may be configured.

<About sheet Sf with film>
In the sheet Sf with a film, which is an object to be peeled off, the film f is laminated on the sheet S. The sheet Sf with a film has an adhesive layer between the sheet S and the film f (for example, tape) and a sheet Sf without an adhesive layer between the sheet S and the film f (for example, PET film). ) Etc. are included. Here, the sheet Sf with a film in the present embodiment is thinned, and the thicknesses of the sheet S and the film f are 50 (μm) and 20 (μm), respectively. Not limited to this, for example, the thickness of the sheet S and the thickness of the film f may be set to 1 (μm) or less, respectively.

<About the peeling process in the peeling mechanism>
The peeling step in the peeling mechanism 100 will be described with reference to FIGS. 3 to 7. The peeling mechanism 100 is driven mainly by the control means and is executed according to an instruction from the control means. Here, FIG. 3 (b), FIG. 3 (d), FIG. 4 (b), FIG. 4 (d), FIG. 5 (b), FIG. 5 (d), FIG. 6 (b), FIG. 6 (d). And FIG. 7B, for convenience of explanation, the outer shape of the peeling head 10 is shown by a broken line, and the nozzle 11a is shown by a solid line.

<Cooling preparation operation>
First, the cooling preparation operation will be described with reference to FIGS. 3 (a) and 3 (b). In the initial state, the peeling head 10 is stopped at the standby position D, and the nozzle 11a is arranged so as to face the horizontal direction. Further, the sheet Sf with a film, which is the object to be peeled off, is suction-fixed on the peeling stage 20 via the suction plate 21.

The peeling head 10 is moved from the standby position D to the starting position E in the diagonal direction L (arrow III (1) direction) by the peeling head driving means. At this time, the adhesive roller 12 is arranged above one of the corners (later peeling starting point Ra) of the sheet Sf with a film. After that, the peeling head 10 is moved downward in the Z-axis direction (arrow IV (2) direction) by the peeling head driving means. Further, the nozzle 11a is rotated in the rotation direction (arrow V (3) direction) by the nozzle drive mechanism, and is arranged to face one of the corners of the film-attached sheet Sf.

Here, the arrangement of the nozzles 11a can be adjusted according to the type (for example, thickness) of the sheet Sf with a film. For example, when the sheet Sf with a film is relatively thin, the rigidity of the film f and the sheet S can be increased by cooling the sheet Sf with a film from above. Therefore, the nozzle 11a is separated from the sheet Sf with the film upward (arrow IV (2) direction) and largely rotated in the rotation direction (arrow V (3) direction) to inject the cooling fluid at an injection angle α (). (See FIG. 3 (c)) is set relatively large. On the other hand, when the film f of the sheet Sf with a film is relatively thick, the rigidity of the film f and the sheet S can be increased by cooling the sheet Sf with a film from the side. Therefore, the nozzle 11a is brought closer to the sheet Sf with the film in the downward direction (arrow IV (2) direction) and slightly rotated in the rotation direction (arrow V (3) direction) to inject the cooling fluid. Set α (see FIG. 3 (c)) relatively small.

<About the operation of forming the peeling starting point>
Next, with reference to FIGS. 3 (c) and 3 (d), a peeling starting point forming operation when the sheet Sf with a film is relatively thin will be described. It should be noted that when the film f of the sheet Sf with a film is relatively thick, the injection angle α of the cooling fluid is different from that of the case where the sheet Sf with a film is relatively thin, and thus the description thereof will be omitted.

As a cooling process, the cooling module 11 injects a cooling fluid from above the film-attached sheet Sf in a state where the nozzle 11a is arranged to face one of the corners of the film-attached sheet Sf. As a result, in the local cooling region where the cooling fluid is injected in the sheet Sf with the film, the rigidity of the film f and the sheet S is temporarily higher than that in the non-cooling region, so that the film f and the sheet S are temporarily larger in rigidity. Integration is suppressed. Therefore, this local cooling region can be formed as the peeling starting point Ra, and the peeling of the film f can be started from the sheet S.

Here, the sheet Sf with a film has an adhesive layer between the sheet S and the film f, and the adhesive force (chemical bonding force) of the adhesive layer is the adhesive force between the sheet S and the film f. There is no adhesive layer between the sheet S and the film f, and the bonding force due to the anchor effect (mechanical bonding force), the bonding force due to the interaction between molecules (physical bonding force), etc. are with the sheet S. There is something that provides adhesion to the film f. In the conventional peeling mechanism, the adhesive layer is foamed and expanded by heat-treating the sheet Sf with a film having an adhesive layer, and the adhesive force between the sheet S and the film f is lowered.

On the other hand, the peeling mechanism 100 of the present embodiment can easily form the peeling starting point Ra on each sheet Sf with a film regardless of the presence or absence of the adhesive layer. The state in which the peeling starting point Ra, which is the cooling region, is formed is temporary, and changes to the atmospheric temperature due to a change with time. Therefore, it is necessary that the peeling starting point Ra is quickly peeled off after the peeling starting point Ra is formed by the injection of the cooling fluid.

In the peeling mechanism 100 of the present embodiment, the rigidity of each of the film f and the sheet S is increased by performing the cooling treatment, and the integration of the film f and the sheet S is suppressed, which is a problem of the conventional peeling mechanism. The point (difficult to form the peeling starting point) can be eliminated, and the peeling operation can be smoothly performed without damaging the sheet S.

In the present embodiment, a peeling starting point Ra is formed at one of the corners of the film-attached sheet Sf, and the film f is formed from the sheet S toward the center position A of the film-attached sheet Sf from the peeling starting point Ra. It is to be peeled off. This can shorten the formation time of the peeling starting point Ra as compared with the case of forming a uniform peeling starting point Ra along one side of the sheet Sf with a film, and can peel off the film f from the sheet S. It can be maintained uniformly along the line. Further, the cooling module 11 in the present embodiment injects a cooling fluid when forming the peeling starting point Ra, but is not limited to this, and for example, the nozzle 11a is configured to be able to scan in the horizontal direction. When the film f is peeled off from the sheet S, the cooling fluid may be sprayed onto the side portions of the sheet S and the film f while scanning in the horizontal direction.

<Adhesive operation>
The adhesive operation will be described with reference to FIGS. 4 (a) and 4 (b). The peeling head 10 is moved downward in the Z-axis direction (arrow IV (4) direction) by the peeling head driving means, and the adhesive surface having adhesiveness on the outer peripheral surface 12b of the adhesive roller 12 is the peeling starting point portion of the film f. It is in contact with the area corresponding to Ra. At this time, the peeling head driving means adjusts the pushing amount of the urging member 13 in the urging direction (arrow VI (5) direction), so that the adhesive roller 12 presses the film f with a desired urging force. Will be done. As a result, the region corresponding to the peeling starting point Ra of the film f is reliably and adhesively held by the adhesive surface of the adhesive roller 12. Further, the nozzle 11a is rotated in the rotation direction (arrow V (6) direction) by the nozzle drive mechanism, and is returned to the initial state facing the horizontal direction. As a result, the nozzle 11a can avoid interference with other members in the subsequent peeling operation.

<About winding operation>
The winding operation will be described with reference to FIGS. 4 (c) and 4 (c). First, the peeling head 10 is moved in the diagonal direction L (arrow III (7) direction) from the start position E to the center position A by the peeling head driving means.

In this winding operation, the cooling effect at the peeling starting point Ra is maintained, and the rigidity of the film f and the sheet S is still higher than that in the non-cooling region. Further, the adhesive roller 12 is always loaded in the urging direction (arrow VI (5) direction) by the urging member 13, and the film f is adhesively held on the adhesive surface of the adhesive roller 12. Further, the adhesive force of the adhesive surface of the adhesive roller 12 to the film f is set higher than the adhesive force generated at the interface between the sheet S and the film f.

Next, as the peeling head 10 moves in the diagonal direction L (arrow III (7) direction), the adhesive roller 12 is rotated in the rotation direction (arrow VII (8) direction) about the rotation axis 13a. .. At this time, by rolling the outer peripheral surface 12b of the adhesive roller 12 with respect to the film f, the adhesive is held so as to be wound around the adhesive surface of the adhesive roller 12 in order from the region corresponding to the peeling starting point Ra of the film f. At the same time, a peeling line Pl1 is formed.

By winding the film f around the adhesive roller 12, the area where the adhesive is held can be increased, that is, the adhesive force of the adhesive roller 12 to the film f can be increased. Here, for the subsequent clamping operation, the tip of the film f wound around the adhesive roller 12 is located above the straight line connecting the protrusion 14a of the clamp claw 14 and the rotation shaft 13a of the adhesive roller 12 in the Z-axis direction. Wrapped up to.

In the present embodiment, the time from the peeling starting point forming operation to the winding operation is set to 0 (s) to 30 (s), but may be set to 0 (s) to 10 (s). preferable. As described above, in the present embodiment, the peeling is performed at the peeling starting point Ra within the time during which the cooling effect at the peeling starting point Ra is maintained (for example, within a few seconds after injecting the cooling fluid). The operation can be performed smoothly.

<About pulling operation>
The pulling operation will be described with reference to FIGS. 5 (a) and 5 (b). This pulling operation is to prevent the peeling head 10 from physically interfering with the peeling stage 20, the suction plate 21, the sheet S, and the peeled film f in the subsequent peeling operation (horizontal direction). It is something to do.

The peeling head 10 is moved upward in the Z-axis direction (arrow IV (9) direction) by the peeling head driving means. At this time, the adhesive roller 12 is loaded in the urging direction (arrow VI (10) direction) by the urging member 13, and a part of the film f is wound around the adhesive roller 12, so that the film f A tensile force is generated in the film f between the adhesive boundary line fa and the peeling line Pl2. Due to this tensile force, the film f is newly peeled from the sheet S and moves from the peeling line Pl1 to the peeling line Pl2. Here, by adjusting the frictional force generated between the adhesive roller 12 and the urging member 13 when the adhesive roller 12 rotates, it is possible to prevent the adhesive roller 12 from rotating in the pulling operation. .. Further, since the adhesive force of the adhesive roller 12 to the film f is increased by winding the film f around the adhesive roller 12, it is possible to prevent the film f from falling from the adhesive roller 12 during the pulling operation.

<Clamp operation>
The clamping operation will be described with reference to FIGS. 5 (c) and 5 (d). This clamping operation is performed to continuously peel the film f from the sheet S in the subsequent peeling operation (horizontal direction).

The clamp claw 14 moves in the proximity direction (arrow VIII (11) direction) by the clamp claw drive mechanism. At this time, the film f wound around the adhesive surface of the adhesive roller 12 is sandwiched between the protrusion 14a of the clamp claw 14 and the adhesive roller 12. Thereby, in addition to the adhesive force of the adhesive roller 12, the film f can be more firmly supported by the adhesive roller 12 by the holding force between the clamp claw 14 and the adhesive roller 12.

<Peeling operation (horizontal direction)>
The peeling operation (horizontal direction) will be described with reference to FIGS. 6 (a) and 6 (b). The peeling head 10 is moved to the center position A by the peeling head driving means in the diagonal direction L (arrow III (12) direction). Here, as the peeling head 10 moves toward the center position A, the length of the peeling line (Pl2, Pl3)), that is, the peeling region increases, and the peeling force becomes relatively large. Therefore, the angle β1 formed by the region where the film f is adhered to the sheet S and the peeled region via the peeling line Pl3 is set to a relatively small acute angle, and the diagonal direction L (arrow III (12)). ) Direction) is set to a relatively low speed (for example, 1 (mm / sec) to 50 (mm / sec)). As a result, as shown in FIG. 6A, the adhesive force of the adhesive roller 12 and the holding force between the clamp claw 14 and the adhesive roller 12 are generated (substantially horizontal direction), and the film f is generated by the peeling head driving means. The direction of the tensile force can be matched, the film f can be prevented from falling off from the adhesive roller 12, and the film f can be reliably peeled off from the sheet S.

<Peeling operation (diagonally upward)>
The peeling operation (oblique upward direction) will be described with reference to FIGS. 6 (c) and 6 (d). The peeling head 10 is moved diagonally upward in the diagonal direction L and upward in the Z-axis direction (arrow IX (13) direction) by the peeling head driving means. Here, as the peeling head 10 moves from the center position A to the end position F, the length of the peeling line (Pl3, Pl4)), that is, the peeling region decreases, and the peeling force becomes relatively small. Therefore, the angle β2 formed by the region where the film f is adhered to the sheet S and the region where the film f is peeled off is set to a relatively large obtuse angle via the peeling line Pl4, and is diagonally upward (arrow IX (13). ) Direction) is set to a relatively high speed (for example, 10 (mm / sec) to 100 (mm / sec)). As a result, as shown in FIG. 6C, the adhesive force of the adhesive roller 12 and the holding force between the clamp claw 14 and the adhesive roller 12 are generated (substantially horizontal direction), and the film f is generated by the peeling head driving means. Even if the direction of the tensile force is slightly different, the film f can be quickly peeled off from the sheet S without falling off from the adhesive roller 12.

<At the end of peeling>
The time when the peeling is completed will be described with reference to FIGS. 7 (a) and 7 (b). The peeling head 10 is moved to the end position F by the peeling head driving means. The peeled film f is hung from the adhesive roller 12. The peeled film f is sucked or gripped by a recovery mechanism (not shown) (for example, a suction cup, a hand, etc.), and then the clamp claw 14 is separated from the adhesive roller 12 by the clamp claw drive mechanism and clamped. The holding force between the claw 14 and the adhesive roller 12 is released. Further, the recovery mechanism is moved to the upper side of the recovery box (not shown) by the recovery mechanism driving means (not shown), and then the suction or grip is released. As a result, the film f is peeled off from the adhesive roller 12 and discharged to the collection box. After that, the peeling head 10 moves to the standby position D, which is the initial state, and performs a peeling step on the other sheet with film Sf.
