Technical Field
The invention relates to a film take-out device and a method for manufacturing a flexible printed circuit board.
Background
In a manufacturing process of a flexible printed circuit board, there are: and a step of taking out one film-like member from a portion where a plurality of film-like members such as copper foils are laminated and supplying the film-like member to another processing portion. As an apparatus for taking out a film-like member used for manufacturing a flexible printed circuit board, there is an apparatus disclosed in patent document 1. In the configuration disclosed in patent document 1, as a mechanism for preventing two film-like members from being taken out simultaneously, specifically, the following is made: in a state where a plurality of film-like members are stacked, the film-like member located at the uppermost position in the stacking sequence is sucked by a vacuum chuck, and then the first cylinder is operated to raise the moving frame.
[ Prior art documents ]
[ patent document ]
Patent document 1: japanese Kokai and JP 59-108744A
However, in the configuration disclosed in patent document 1, the vacuum chucks on the fixed frame side and the moving frame side are pressed in a state where a plurality of film-like members are stacked, and in this pressed state, the moving frame side is raised without raising the fixed frame side. Therefore, the film-like member may be bent and twisted. In particular, since the copper foil is easily deformed such as bent or folded, if one side of the moving frame is raised in a pressed state by the vacuum chuck, the copper foil becomes a cause of the distortion.
Such distortion is not preferable because it causes a failure in the production of a flexible printed wiring board.

The film-like member S is a film-like member used for manufacturing a flexible printed circuit board, and is, for example, a copper foil sheet, a polyimide sheet, or the like. In addition, as for the film-like member S such as a copper foil sheet or a polyimide film, for example, other film members such as a release film (protective film) or a protective film may be attached to a base material such as a copper foil film or a polyimide film, but such film members may not be attached. When another film member is attached to a base material such as a copper foil material or a polyimide material in the film-like member S, the film-like member S is likely to be warped due to a difference in thermal shrinkage rate between the base material and the film member.
(regarding control action)
A method for manufacturing a flexible printed circuit board using the film take-out
(1) A first step: suction holding of the uppermost film-like member S (first control)
First, as shown in fig. 5, a laminate PS in which a plurality of film-like members S are laminated is disposed at a predetermined placement position. Thereafter, as shown in fig. 6, the
Here, the uppermost film-like member S1 in contact with the suction pad 31 may be warped such that the end portion side thereof faces upward (Z1 side). However, the suction cup 31 is provided in a bellows shape so as to be elastically deformable. Therefore, even if the tip of the suction pad 31 comes into contact with the portion of the film-like member S1 where the warpage occurs, the suction pad 31 can be deformed to follow the warpage. Therefore, when the tip of the suction pad 31 comes into contact with the uppermost film-like member S1, the contact portion can be prevented from being damaged.
The
(2) A second step: the uppermost film-like member S1 is separated from the laminate PS (third control)
Next, as shown in fig. 7, the
Specifically, the
(3) A third step: shaking action implementation (second control)
However, when the uppermost film-like member S1 is lifted, the next film-like member S2 adjacent to the uppermost film-like member S1 may be lifted together. In addition, a plurality of film-like members S including the next film-like member S2 may be lifted. In particular, when the surface roughness of the film-like member S is extremely small (when the film-like member S is extremely smooth), air is less likely to enter between adjacent film-like members S, and therefore, such a situation that the film-like members S are closely held to each other (hereinafter, referred to as simultaneous taking out of a plurality of film-like members S) is likely to occur.
Therefore, assuming that the film-like member S1 is closely attached to the other film-like member S after the uppermost film-like member S1 of the stacked body PS is raised, a shaking-off operation for shaking off the other film-like member S is performed. Specifically, the

However, the operation of dropping the other film-like member S on the
First, the first step (the suction and holding of the uppermost film-like member S) similar to the step described above with reference to fig. 6 is performed. The first step is already described, and therefore, the description thereof is omitted. Next, as an operation combining the second step (separating the uppermost film-like member S1 from the stacked body PS) and the third step (performing the shake-off operation), the following operations of the eighth step to the eleventh step are performed.
(8) An eighth step: the
After the first step, the
By performing such an operation of twisting the film-like member S1, air easily enters between the film-like member S1 and the other film-like member S closely attached thereto, and thus most of the other film-like members S fall off the film-like member S1.
(9) A ninth step: the suction-holding
Next, the
At this time, the film-like member S1 is restored from the twisted state, and the entire rear side (Y2 side) thereof is raised. By performing this operation, air is likely to enter between the film-like member S1 and the other film-like member S in close contact therewith, and thus most of the other film-like member S falls off the film-like member S1.
(10) A tenth step: the
Next, the
By performing such an operation of twisting the film-like member S1, air more easily enters between the film-like member S1 and the other film-like member S in close contact therewith, and thus most of the other film-like member S falls off from the film-like member S1.
(11) An eleventh step: the
Next, the
At this time, the film-like member S1 is restored from the twisted state, and the entire rear side (Y2 side) thereof is raised. By performing such an operation, air easily enters between the film-like member S1 and another film-like member S in close contact therewith, and the other film-like member S falls off from the film-like member S1.
By performing the operations of the eighth step to the eleventh step as described above, air easily enters between the film-like member S1 and the other film-like member S adhered thereto, and thus the other film-like member S adhered to the film-like member S1 falls off from the film-like member S1.
After the eleventh step, the fourth step (insertion of the separation plate 71), the fifth step (release of suction and holding of the uppermost film-like member S1), the sixth step (suction and holding of the uppermost film-like member S1 by the suction base 220), and the seventh step (lowering (returning to the initial position) of the mounting table 201) are sequentially performed as described above.
In addition, after the above-described respective steps, the respective steps for manufacturing the flexible printed circuit board are performed, thereby manufacturing the flexible printed circuit board as a product.

Therefore, after the uppermost film-like component S1 is sucked and held by the suction holding section 30 (first suction member) and the suction holding section 130 (second suction member) by the first control, by the second control, after the first control, by raising or lowering either one of the suction holding section 30 (first suction member) and the suction holding section 130 (second suction member) relative to the other one, air easily enters between the sucked and held film-like component S and the other film-like component S in close contact therewith, and thereby most of the other film-like components S fall off from the film-like component S1. Therefore, it is possible to prevent a plurality of film-like members S from being taken out at the same time.
In order to prevent such simultaneous removal of a plurality of film-like members S, the film-like members S have been manually removed in the related art, but in the present embodiment, the film-like members S can be automatically removed by using the
In addition, since the operation for preventing the simultaneous removal of the plurality of film-like components S is performed by the relative vertical movement between the suction holding portion 30 (first suction member) and the suction holding portion 130 (second suction member), the film-like components S can be formed without being twisted.
In the present embodiment, the
Therefore, even if deformation such as warpage occurs in the film-like member S, a space for dropping the other film-like member S adhered to the film-like member S1 can be secured. Further, a sufficient space for performing the relative elevating operation between the suction holding portion 30 (first suction member) and the suction holding portion 130 (second suction member) can be secured, and thus the other film-like member S adhering to the film-like member S1 can be favorably dropped.
Further, in the present embodiment, the lifting mechanism 60 (first lifting member) includes a lifting cylinder 62 (first lifting member on one side) for raising and lowering one side in the longitudinal direction of the suction holding portion 30 (first suction member), and a lifting cylinder 62 (first lifting member on the other side) for raising and lowering the other side in the longitudinal direction of the suction holding portion 30 (first suction member). The lifting mechanism 160 (second lifting member) includes a lifting cylinder 162 (one second lifting member) for raising or lowering one side in the longitudinal direction of the suction holding portion 130 (second suction member) and a lifting cylinder 162 (the other second lifting member) for raising or lowering the other side in the longitudinal direction of the suction holding portion 130 (second suction member). In the second control, the
In the present embodiment, in the second control, the operations of the elevation mechanism 60 (first elevation member) and the elevation mechanism 160 (second elevation member) are controlled to move one of the suction-holding portion 30 (first suction member) and the suction-holding portion 130 (second suction member) in the direction of separating from the stacked body PS and to move the other of the suction-holding portion 30 (first suction member) and the suction-holding portion 130 (second suction member) in the non-moving state, and after the start of the operation, the operations of the elevation mechanism 60 (first elevation member) and the elevation mechanism 160 (second elevation member) are controlled to move the other of the suction-holding portion 30 (first suction member) and the suction-holding portion 130 (second suction member) in the non-moving state and to move the remaining one of the suction-holding portion 30 (first suction member) and the suction-holding portion 130 (second suction member) in the direction of separating from the stacked body PS And (4) moving.
Therefore, as shown in fig. 8 or 13, since either one of the suction-holding portion 30 (first suction member) and the suction-holding portion 130 (second suction member) is in a state of being raised or lowered with the other one as a fulcrum, air easily enters between the film-like member S1 and the other film-like member S in close contact therewith. This enables the other film-like member S to be favorably dropped from the uppermost film-like member S1, and thus, the simultaneous removal of a plurality of film-like members S can be favorably prevented.
Further, in the present embodiment, the film take-out
Therefore, when the holding of the film-like member S1 sucked and held by the suction and holding

In the present embodiment, the
In addition, the method for manufacturing a flexible printed circuit board according to the present embodiment includes: a suction step of controlling the operations of the lifting mechanism 60 (first lifting means) and the lifting mechanism 160 (second lifting means) so that the uppermost film-like component S1 stacked on the stack PS is sucked and held by the suction holding section 30 (first suction means) capable of sucking and holding one edge portion side of the film-like component S1 and the suction holding section 130 (second suction means) capable of sucking and holding the other edge portion side of the film-like component S1; and a shaking-off step of, after the suction step, shaking off the other film-like component S other than the film-like component sucked and held by the suction holding portion 30 (first suction member) by operating at least one of the elevating mechanism 60 (first elevating member) and the elevating mechanism 160 (second elevating member) so as to raise or lower the other one of the suction holding portion 30 (first suction member) and the suction holding portion 130 (second suction member) relative to the other one of the two members, the elevating mechanism 60 (first elevating member) raising or lowering the suction holding portion 30 (first suction member) and the elevating mechanism 160 (second elevating member) raising or lowering the suction holding portion 130 (second suction member).
Therefore, after the suction step is performed to bring the uppermost film-like component S1 into a state of being sucked and held by the suction holding section 30 (first suction member) and the suction holding section 130 (second suction member), the shake-off step is performed to cause either one of the suction holding section 30 (first suction member) and the suction holding section 130 (second suction member) to be raised or lowered relative to the other one, so that air easily enters between the sucked and held film-like component S1 and the other film-like component S in close contact therewith, and most of the other film-like component S is dropped from the film-like component S1. Therefore, it is possible to prevent a plurality of film-like members S from being taken out at the same time.
In order to prevent such simultaneous removal of a plurality of film-like members S, the film-like members S are conventionally removed manually, but in the present embodiment, the film-like members S can be automatically removed by using the
In addition, since the operation for preventing the simultaneous removal of the plurality of film-like components S is performed by the relative vertical movement between the suction holding portion 30 (first suction member) and the suction holding portion 130 (second suction member), the film-like components S can be formed in a state where no distortion occurs.

In addition, although each of the control operations described above may be performed such that the next control operation is started after a certain control operation is completed, the next control operation may be started at the same time as the certain control operation is completed or before the certain control operation is completed.
The film-like member S in the above embodiment may be a single-sided copper foil material in which a copper foil is present only on one side of a base material such as a polyimide film, a double-sided copper foil material in which copper foils are present on both sides of the base material, or a multilayer material having a multilayer copper foil of a double-sided copper foil material or more. The film-like member S may include an adhesive layer or a release film for protecting the adhesive layer, in addition to the base material and the copper foil. When such an adhesive layer or release film is provided, the thickness of the film-like member S is increased as compared with the case where the adhesive layer or release film is not provided. Therefore, even if the film-like member S is warped, scratches are less likely to be generated when the
