Hereinafter, the film take-out device 10 according to an embodiment of the present invention will be described. In the following description, the longitudinal direction of the support shaft 41 is referred to as the X direction, the X1 side is the right side of the paper surface in FIG. 1, and the X2 side is the left side of the paper surface in FIG. 1. In addition, let the direction connecting the first suction unit 20 and the second suction unit 120 be the Y direction, the Y1 side is the front side of the paper in FIG. 1, and the Y2 side is the rear side of the paper in FIG. 1. In addition, the direction (vertical direction) connecting the suction base 220 and the mounting table unit 200 in FIG. 5 is taken as the Z direction, the Z1 side is the paper back side (upper side) in FIG. 5, and the Z2 side is the paper front side in FIG. 5 ( Lower side). (About the structure of the film take-out device)

FIG. 1 is a schematic diagram showing the configuration of the film take-out device 10. As shown in FIG. 1, the main constituent elements of the film take-out device 10 include a first suction unit 20, a second suction unit 120, a stage unit 200, a control unit 210, and a suction base 220 (see FIG. 5 ).

Among them, the first suction unit 20 includes a suction holding unit 30, a rotation mechanism 40, a suction mechanism 50, a lifting mechanism 60, and a separation plate unit 70. Among them, the suction holding portion 30 corresponds to a part of the first suction member. In addition, the first suction member corresponds not only to the suction holding portion 30 but also to the suction mechanism 50.

FIG. 2 is a diagram showing a schematic configuration of the adsorption and holding unit 30. The suction holding portion 30 shown in FIG. 2 is a portion that suction-holds the film-shaped member S, and the suction holding portion 30 is attached to a support shaft 41 that constitutes the rotating mechanism 40. The suction holding portion 30 includes a suction chuck 31 that is attached to the support arm 32.

The material of the suction pad 31 is formed of an elastic member having elasticity such as rubber or an elastic body. Therefore, the configuration is such that even if the film contact portion 31 a of the front end side of the suction chuck 31 abuts on the film-shaped member S, the film-shaped member S will not be damaged. In addition, the suction chuck 31 is a cylindrical member provided in a wrinkle shape. Therefore, the direction of the film contact portion 31a can easily change following the film-shaped member S, and therefore, even if deformation such as warpage occurs in the film-shaped member S, it can follow the deformation.

In addition, the suction chuck 31 is attached to the front end side (one end side) of the support arm 32. The support arm 32 is formed of a rigid member such as metal. The support arm 32 can support the suction chuck 31 and the suction branch pipe. In addition, the support arm 32 is rotated by the rotation mechanism 40, and thus, it is configured to be able to perform the contact operation of bringing the suction chuck 31 into contact with the film member S and the retreating operation of separating the suction chuck 31 from the film member S.

FIG. 3 is a diagram showing a schematic configuration of the suction holding section 30, the rotation mechanism 40, the suction mechanism 50, and the lifting mechanism 60. The rotation mechanism 40 includes a support shaft 41, a support column 42, and a rotation driver 43. The support shaft 41 is a portion to which the other end side of the support arm 32 is attached, and is a member that is rotated by the operation of a rotation driver 43 described later. The support shaft 41 is a shaft member that is rotatably supported on the support column 42 in at least two locations. In addition, the support column 42 is a member erected from the frame 44 and is a portion that supports the support shaft 41 or the suction holding portion 30. The frame 44 is a member that supports the support column 42. For example, a long member made of metal disposed below the support column 42 is a frame.

In addition, on one end side of the support shaft 41, a driver 43 for rotation is mounted via a drive transmission mechanism 45. The operation of the rotation driver 43 causes the support shaft 41 to rotate. One end of the rotation operation is the end point of the contact operation of the suction chuck 31 against the film member S, and the other end of the rotation operation is the end point of the retraction operation of the suction chuck 31 separated from the film member S. Here, as the rotation driver 43, for example, an air cylinder, a hydraulic cylinder, an electromagnetic cylinder, an electromagnetic coil, a motor, and the like can be used. In addition, the rotation driver 43 may be directly connected to the support shaft 41.

In addition, the suction mechanism 50 includes a suction pump 51 and a suction duct 52. The suction pump 51 is a member that applies negative pressure for sucking and holding the film-shaped member S through the suction pad 31. One end of the suction duct 52 is connected to the suction pump 51, and the other end of the suction duct 52 is connected to the suction chuck 31. Therefore, when the suction pump 51 operates and the suction chuck 31 abuts on the film-shaped member S, the film-shaped member S can be sucked and held through the suction chuck 31.

In addition, as for the suction duct 52, any member can be used as long as it is a tubular member capable of circulating air, such as a duct formed of an elastic material, a duct made of metal or resin, or the like. In addition, when the support arm 32 is provided in a cylindrical shape, the support arm 32 is also a constituent element of the suction duct 52.

In addition, the elevating mechanism 60 is a mechanism for raising or lowering at least a part of the above-mentioned suction holding portion 30, the rotating mechanism 40, and the suction duct 52. In addition, the lift mechanism 60 may be configured not only to raise or lower at least a part of the suction duct 52, but also to raise or lower the suction pump 51. In addition, the lifting mechanism 60 corresponds to the first lifting member. The elevating mechanisms 60 are arranged on both ends of the frame 44 in the longitudinal direction. The lifting mechanism 60 includes a suspension member 61 and a lifting cylinder 62.

The suspension member 61 is a mechanism that connects the end of the frame 44 and the front end of the piston rod of the lift cylinder 62. For example, the suspension member 61 may use a link mechanism or a bearing. In particular, when the link mechanism is used, the lifting cylinder 62 at one end of the frame 44 and the lifting cylinder 62 at the other end of the frame 44 can be raised or lowered at different timings. The frame 44 and the suction holding portion 30 supported by the frame 44 are inclined.

However, the suspension member 61 may not use a link mechanism or a bearing, but may use a columnar member made of metal, for example, to connect the frame 44 and the lift cylinder 62. In addition, the piston rod of the lifting cylinder 62 is usually not tiltable. Therefore, when the suspension member 61 is made of a metal columnar member, it is preferable to make the lifting cylinder 62 at one end of the frame 44 and the other end of the frame 44 The lifting cylinder 62 moves up or down at the same timing.

In addition, the lifting cylinder 62 is a member that applies a driving force, and the driving force is used to raise or lower the frame 44 or the suction holding section 30 and the like. As the lift cylinder 62, for example, an air cylinder, a hydraulic cylinder, an electromagnetic cylinder, an electromagnetic coil, a motor, and the like can be used.

FIG. 4 is a diagram showing a schematic structure of the separation plate unit 70. As shown in FIG. 4, the separation plate unit 70 includes a separation plate 71, a support arm 72, a connecting beam 73, a separation plate driver 74 and a guide member 75. The separation plate 71 is a plate-shaped member that is inserted when it is raised while maintaining the state where the uppermost film-like member S of the laminated body PS (refer to FIG. 5) is held by the suction holding section 30. The raised film-like member S and the film-like member S located directly below the raised film-like member S. Through the insertion of the separation plate 71, even if the film-like member S held by the suction holding section 30 is lowered later, the film-like member S held by the suction holding section 30 can be prevented from being in close contact with the film-like member S directly below and cannot be separated . In addition, the separation plate 71 corresponds to a separation member.

Here, the separation plate 71 is formed of a material that does not easily damage the film-shaped member S. Specifically, the separation plate 71 is formed of a material that can be easily deformed even if a pressing force is applied to the film-shaped member S. Examples of such a material include spring steel and elastic resin. In addition, from the viewpoint of preventing dust from adhering to the film-shaped member S, the material of the separation plate 71 is preferably spring steel.

In addition, the support arm 72 is a member that supports the separation plate 71, and the support arm 72 holds one end side of the separation plate 71. In addition, the connection beam 73 is a member that connects a plurality of support arms 72 (three in FIG. 1 and FIG. 4 ). In addition, the separation plate driver 74 corresponds to the moving member, and is a part that moves the support arm 72 toward or away from the film-like member S. As such a separation plate driver 74, for example, an air cylinder, a hydraulic cylinder, an electromagnetic cylinder, an electromagnetic coil, a motor, and the like can be used. In addition, in the present embodiment, the separating plate driver 74 is installed so as to be able to move the connecting beam 73. The guide member 75 is a member that guides the movement of the connecting beam 73 based on the operation of the separation plate driver 74. The guide member 75 is, for example, a rail-shaped member or a linear rail.

In addition, as shown in FIG. 1, the second adsorption unit 120 has the same configuration as the first adsorption unit 20. Specifically, the second suction unit 120 includes a suction holding unit 130, a rotation mechanism 140, a suction mechanism 150, a lifting mechanism 160, and a separation plate unit 170.

That is, the suction holding portion 130 includes the suction chuck 131 having the film contact portion 131 a and the support arm 132. In addition, the suction holding portion 130 corresponds to a part of the second suction member. In addition, the rotation mechanism 140 includes a support shaft 141, a support column 142, a rotation driver 143, and a frame 144. In addition, the suction mechanism 150 includes a suction pump 151 and a suction duct 152. In addition, the suction mechanism 150 corresponds to a part of the second suction member. In addition, the lifting mechanism 160 includes a suspension member 161 and a lifting cylinder 162. In addition, the lifting mechanism 160 corresponds to the second lifting member. In addition, the separation plate unit 170 includes a separation plate 171, a support arm 172, a connecting beam 173, a separation plate driver 174, and a guide member 175. In addition, the separation plate 171 corresponds to the separation member, and the separation plate driver 174 corresponds to the moving member. Each of these parts has the same structure as that of the corresponding part of the first adsorption unit 20, and therefore, its description is omitted.

In addition, the film take-out device 10 includes a mounting table unit 200. FIG. 5 is a schematic diagram showing the configuration of the film take-out device 10 including the mounting table unit 200 and the suction base 220, and is a view of the film take-out device 10 viewed from the side. As shown in FIG. 5, the mounting table unit 200 has a mounting table 201, an elevating guide 202, and a mounting table air cylinder 203.

The mounting table 201 is a plate-shaped member, and a plurality of film-shaped members S are mounted on the upper surface of the mounting table 201. In addition, the elevating guide 202 is a member capable of guiding the mounting table 201 along the edge of the mounting table 201 at a predetermined interval (for example, a concave portion provided on the edge of the mounting table 201). The vertical direction (Z direction) rises or falls without positional deviation. In addition, the air cylinder 203 for the mounting table is a member that imparts a driving force to move the mounting table 201 in the vertical direction (Z direction). As the air cylinder 203 for the mounting table, for example, an air cylinder, a hydraulic cylinder, an electromagnetic cylinder, an electromagnetic coil, a motor, and the like can be used.

In addition, the film take-out device 10 includes a control unit 210. The control unit 210 is a part that controls the driving of each driving part of the first suction unit 20 and the second suction unit 120. Specifically, the control unit 210 controls the driving of the rotation drivers 43 and 143, the suction pumps 51 and 151, the lift cylinders 62 and 162, and the separation plate drivers 74 and 174.

In addition, the control unit 210 is, for example, a computer. The control unit 210 can execute various control operations by executing predetermined control data and a predetermined control program stored in a memory including an external memory device. In addition, the control operation performed by the control unit 210 will be described later.

As shown in FIG. 5, the suction base 220 includes a suction plate 221, a moving mechanism connecting portion 222, a suction member (not shown), and a moving mechanism (not shown). The suction plate 221 is provided with a plurality of suction holes (not shown). Therefore, the suction plate 221 can attract the film-shaped member S in a planar shape. In addition, the moving mechanism connecting portion 222 is a portion connected to a moving mechanism not shown in the figure. Therefore, by the operation of the moving mechanism, the suction plate 221 can be lowered, or the film-shaped member S sucked by the suction base 220 can be transported to another processing site.

In addition, the film-shaped member S is a film-shaped member used in the manufacture of a flexible printed circuit board, and is, for example, a copper foil sheet, a polyimide sheet, or the like. In addition, for the film-like member S such as a copper foil sheet or a polyimide film, for example, a release film or a protective film may be attached to a base material such as a copper foil film or a polyimide film. Other film parts, but it is not necessary to stick such film parts. When other film members are attached to a base material such as a copper foil material or a polyimide material in the film member S, due to the difference in thermal shrinkage between the base material and the film member, it becomes easy Warped state.

(About control actions) Hereinafter, a method for manufacturing a flexible printed circuit board using the film take-out device 10 configured as described above will be described. In the following description, the first step to the seventh step are described in order. Of course, there may be various other steps in addition to these steps.

(1) First step: adsorption and retention of the uppermost film-like member S (first control) First, as shown in FIG. 5, the stacked body PS on which a plurality of film-shaped members S are stacked is arranged on a predetermined placement site. After that, as shown in FIG. 6, the control unit 210 operates the mounting table cylinder 203 to raise the mounting table 201 to a predetermined ascending position, whereby the front end of the suction chuck 31 of the suction holding unit 30 can be brought into contact On the uppermost film-shaped member S of the laminate PS (hereinafter, this film-shaped member S is referred to as a film-shaped member S1). At this time, the control unit 210 operates the suction pump 51 of the suction mechanism 50 to suck and hold the uppermost film-shaped member S through the suction chuck 31.

Here, on the uppermost film-like member S1 that is in contact with the suction chuck 31, warpage may sometimes occur as the end side faces upward (Z1 side). However, the suction chuck 31 is provided in a bellows shape, so that it can be elastically deformed. Therefore, even if the front end portion of the suction chuck 31 abuts on the warped portion of the film-like member S1, the suction chuck 31 can be deformed in a manner to imitate the warpage. Therefore, when the front end portion of the suction chuck 31 abuts on the uppermost film-like member S1, damage to the abutment portion can be prevented.

In addition, the control unit 210 may operate the lifting cylinder 62 instead of the mounting table cylinder 203 to lower the suction chuck 31 toward the film-shaped member S1. Even so, it is possible to attract and hold the uppermost film-like member S1.

(2) Second step: separating the uppermost film-like member S1 from the laminate PS (third control) Next, as shown in FIG. 7, the control unit 210 operates the stage air cylinder 203 and the lift cylinder 62 to suck and hold the uppermost film-like member S in the suction chuck 31 (that is, the state in which the suction pump 51 operates ), the uppermost film-like member S is separated from the laminate PS.

Specifically, the control unit 210 actuates the mounting table cylinder 203 to lower the mounting table 201 to a predetermined retreat position. Thus, a relatively large space is formed between the laminated body PS and the film-like member S1 that is attracted and held. At this time, even after the film-like member S1 is raised, the top-most film-like member S (hereinafter, the film-like member S will be referred to as the film-like member S2) of the remaining laminate PS is relatively small in the virtual range The ground is warped, and the space between the film-shaped member S and the film-shaped member S2 can also form a gap reliably.

(3) The third step: the implementation of shake-off action (second control) However, when the uppermost film-like member S1 is lifted, sometimes the next adjacent film-like member S2 is also lifted up when the film-like member S1 is stacked. In addition, there are cases where a plurality of film-shaped members S including the next film-shaped member S2 are lifted together. In particular, when the surface roughness of the film-like member S is very small (when the film-like member S is very smooth), air does not easily enter between the adjacent and closely-adjacent film-like members S, and therefore, such a film-like member S is easily generated A case where they are held tightly to each other (hereinafter, referred to as simultaneous removal of a plurality of film-shaped members S).

Therefore, it is assumed that after raising the uppermost film-like member S1 of the laminated body PS and other film-like members S are in close contact with the film-like member S1, the shaking-off operation of shaking off the other film-like member S is performed. Specifically, the control unit 210 controls the lift cylinder 62 on the first suction unit 20 side and the lift cylinder 162 on the second suction unit 120 side to operate not at the same timing but at different timings. Hereinafter, such a shaking-off operation (first operation example and second operation example) will be described.

(3-1) The first action example of shake-off action 8 is a diagram showing a first operation example of the operation timing of the lift cylinder 62 on the first suction unit 20 side and the lift cylinder 162 on the second suction unit 120 side. As shown in FIG. 8, the control unit 210 initially operates the lift cylinder 62 to raise the suction holding unit 30 on the first suction unit 20 side, but at the same timing, does not make the suction holding unit on the second suction unit 120 side 130 rises, but the work of the lift cylinder 162 is stopped. This situation is shown in FIG. 9. Then, when the suction holding portion 30 on the side of the first suction unit 20 is raised, the film-like member S1 is inclined obliquely. Therefore, air easily enters between the film-shaped member S1 and the other film-shaped member S that is in close contact therewith, and thus most of the other film-shaped member S falls from the film-shaped member S1.

Next, as shown in FIGS. 8 and 10, the control unit 210 causes the lift cylinder 162 to operate to move the second suction unit 120 in succession with the movement of the suction holding unit 30 on the first suction unit 20 side to a predetermined position. The suction holding unit 130 on the side rises to a predetermined position. As a result, the suction holding section 30 on the first suction unit 20 side and the suction holding section 130 on the second suction unit 120 side are both raised.

Next, the control unit 210 controls the lift cylinder 62 on the first suction unit 20 side and the lift cylinder 162 on the second suction unit 120 side to operate at different timings again. Specifically, as shown in FIGS. 8 and 11, while maintaining the state where the adsorption holding portion 130 on the second adsorption unit 120 side is raised, the adsorption holding portion 30 on the first adsorption unit 20 side is lowered To the specified location. At this time, the film-shaped member S1 is inclined obliquely so that the suction holding portion 30 side of the first suction unit 20 side is located on the lower side (Z2 side), while the first suction unit 20 side of the film-shaped member S1 becomes different from the next The film-like member S2 is in contact with, but in a state of being spaced from.

Next, as shown in FIGS. 8 and 12, the control unit 210 causes the lift cylinder 162 to operate to maintain the first suction unit in succession after the suction holding unit 30 on the first suction unit 20 side is lowered to a predetermined position. When the state in which the suction holding section 30 on the 20 side is lowered does not change, the suction holding section 130 on the second suction unit 120 side is lowered to a predetermined position. At this time, the second suction unit 120 side of the film-like member S1 is also in a state of being spaced apart from the next film-like member S2 in the same manner as the first suction unit 20 side of the film-like member S1.

Next, as shown in FIGS. 8 and 9, the control unit 210 performs control such that the lift cylinder 62 is operated to be in sequence with the operation of lowering the suction holding unit 130 on the second suction unit 120 side to a predetermined position, The suction holding unit 30 on the first suction unit 20 side is raised again, but at the same timing, the operation of the lift cylinder 162 is stopped without raising the suction holding unit 130 on the second suction unit 120 side.

Next, as shown in FIGS. 8 and 10, the control unit 210 performs control such that the lift cylinder 162 is operated so as to be successive to the operation of raising the suction holding unit 30 on the first suction unit 20 side to a predetermined position, The suction holding portion 130 on the second suction unit 120 side is raised again to a predetermined position. As a result, the suction holding section 30 on the first suction unit 20 side and the suction holding section 130 on the second suction unit 120 side are both raised. As a result, a large gap is formed between the film-shaped member S1 that is sucked and held and the next film-shaped member S2. In addition, by repeating the ascent and descent of the first adsorption unit 20 and the second adsorption unit 120 as described above, air is more likely to enter between the film-shaped member S1 and the other film-shaped member S that is in close contact with it. The film-shaped member S falls from the film-shaped member S1.

Then, move to the fourth step described later. However, in order to more reliably drop the other film-shaped member S from the film-shaped member S1, the shaking-off operation according to FIG. 8 may be repeated again.

(3-2) Second action example of shake-off action Next, a second operation example of the shake-off operation will be described. 13 is a diagram showing a second operation example of the operation timing of the lift cylinder 62 on the first suction unit 20 side and the lift cylinder 162 on the second suction unit 120 side. As shown in FIG. 13, the lift cylinder 62 is initially operated to raise the suction holding portion 30 on the first suction unit 20 side to a predetermined position, but at the same timing, the suction on the second suction unit 120 side is not held The unit 130 is raised, but the operation of the lift cylinder 162 is stopped. This case is the same as the case shown in FIG. 9, and when the suction holding portion 30 on the first suction unit 20 side is raised, the film-like member S1 is inclined obliquely. Therefore, air easily enters between the film-shaped member S1 and the other film-shaped member S that is in close contact therewith, and most of the other film-shaped member S falls from the film-shaped member S1.

Next, as shown in FIGS. 13 and 14, the control unit 210 operates the lift cylinder 162 to raise the suction holding unit 130 on the second suction unit 120 side to a predetermined position, and then causes the second suction unit 120 side The suction holding unit 130 is lowered to a predetermined position, but at the same timing, the operation of the lift cylinder 62 is stopped without lowering the suction holding unit 30 on the first suction unit 20 side. Then, the suction holding portion 130 that has reached the top of the ascent descends again, so that the film-shaped member S1 is in the same state as when it was floating, and air easily enters between the film-shaped member S and the other film-shaped member S that is in close contact with it. As a result, most of the other film-shaped member S falls from the film-shaped member S1. In addition, when the suction holding portion 130 on the second suction unit 120 side is lowered to a predetermined position, the second suction holding portion 120 side of the film-like member S1 is not in contact with the next film-like member S2, but has a space therebetween status.

Further, as shown in FIGS. 13 and 12, the control unit 210 causes the lift cylinder 62 to operate so that the first suction unit 20 is moved in succession with the operation of the suction holding unit 130 on the second suction unit 120 side descending to a predetermined position. The suction holding unit 30 on the side is lowered to a predetermined position, but at the same timing, the operation of the lift cylinder 162 is stopped without raising the suction holding unit 130 on the second suction unit 120 side. At this time, the first suction unit 20 side of the film-like member S1 is also in a state of being spaced apart from the next film-like member S2 in the same manner as the second suction unit 120 side of the film-like member S1.

Next, as shown in FIGS. 13 and 11, the control unit 210 causes the lift cylinder 162 to operate to move the second suction unit 120 in succession to the operation of lowering the suction holding unit 30 on the first suction unit 20 side to a predetermined position. The suction holding section 130 on the side rises, but at the same timing, the operation of the lift cylinder 62 is stopped without raising the suction holding section 30 on the first suction unit 20 side.

Next, as shown in FIGS. 13 and 10, the control unit 210 operates the lifting cylinder 62 to maintain the state in which the suction holding unit 130 on the second suction unit 120 side is raised, and again to make the first The suction holding unit 30 on the suction unit 20 side rises to a predetermined position. As a result, both the suction holding section 30 on the first suction unit 20 side and the suction holding section 130 on the second suction unit 120 side are raised. As a result, a large gap is formed between the film-shaped member S1 that is sucked and held and the next film-shaped member S2. In addition, by repeating the ascent and descent of the first adsorption unit 20 and the second adsorption unit 120 as described above, air is more likely to enter between the film-shaped member S1 and the other film-shaped member S that is in close contact with it. The film-shaped member S falls from the film-shaped member S1.

Then, move to the fourth step described later. However, in order to more reliably drop the other film-shaped member S from the film-shaped member S1, the shaking-down operation based on FIG. 13 may be repeated again.

In addition, the control method of operating the lift cylinder 62 on the first suction unit 20 side and the lift cylinder 162 on the second suction unit 120 side at different timings is not limited to the above-mentioned control method. That is, as long as the other film-shaped member S that is close to the uppermost film-shaped member S1 can be dropped well, the movement of the lift cylinder 62 on the first suction unit 20 side and the lift cylinder 162 on the second suction unit 120 side The timing can be any timing.

(4) Fourth step: insertion of separation plate 71 (fourth control) Next, as shown in FIG. 15, the control section 210 operates the separation plate driver 74 to insert the separation plate 71 into a position where the film-like member S1 and The position between the uppermost film-like member S2 in the remaining laminate PS.

(5) The fifth step: release the suction holding of the uppermost film-like member S1 (fifth control) Next, the control unit 210 actuates the mounting table cylinder 203 to raise the mounting table 201. At the same time, the control unit 210 stops the operation of the suction pump 51 on the first suction unit 20 side and the suction pump 151 on the second suction unit 120 side, and releases the suction holding of the uppermost film-like member S1. At this time, the lift cylinders 62 and 162 may be controlled to lower the suction holding sections 30 and 130.

Then, as shown in FIG. 16, by releasing the suction holding of the uppermost film-like member S1, the uppermost film-like member S1 falls toward the film-like member S2 (laminated body PS). At this time, the separation plate 71 is in a state where the uppermost film-like member S1 and the film-like member S2 are sandwiched. In addition, since the separation plate 71 is formed of an elastically deformable member, even if the separation plate 71 abuts on the film-shaped members S1 and S2, damage to them can be prevented.

In addition, after the suction holding of the film-like member S1 is released, the control unit 210 operates the rotation drivers 43 and 143 to position the suction holding units 30 and 130 at the retracted position (see FIG. 17 ). Thus, even if the suction base 220 is lowered in the next step, interference between the suction holding portions 30 and 130 and the suction base 220 can be prevented.

(6) Sixth step: use the suction base 220 to attract and hold the uppermost film-like member S1 Next, the control unit 210 lowers the suction base 220 while operating the suction member and the moving mechanism (not shown). Then, the suction plate 221 is pressed toward the laminated body PS, so that the laminated body PS is sandwiched between the suction plate 221 and the mounting table 201. At this time, even if warpage occurs in the uppermost film-like member S1, the uppermost film-like member S1 is attracted and held by the suction plate 221 in a state where the warpage is corrected by this pinching operation. This situation is shown in Fig. 17. In addition, even in the state shown in FIG. 17, as in the state shown in FIG. 16, the separation plate 71 is sandwiched between the uppermost film-like member S1 and the film-like member S2.

Here, if the suction plate 221 is strongly pressed, the separation plates 71 and 171 are sandwiched between the laminated body PS and the suction plate 221, thereby possibly causing scratches. In order not to cause such scratches, the suction base 220 is provided with a suction blower (not shown), and the suction plate 221 is gradually lowered while being sucked by the suction blower. Then, preferably, immediately before the suction plate 221 presses the uppermost film-like member S1 to the lower side (Z2 side), the suction is performed so that only the uppermost film-like member S1 is raised. In addition, the suction plate 221 is gradually lowered until the uppermost film-like member S1 is adsorbed and held. After the film-like member S1 is suction-held, the lowering of the suction plate 221 is stopped. Here, in order to determine whether or not the uppermost film-like member S1 is held by suction, the suction base 220 may include a vacuum sensor (not shown).

In addition, when the uppermost film-like member S1 and other film-like members S are warped, if the suction plate 221 does not descend until the uppermost film-like member S1 is flat, the vacuum sensor does not determine the most The upper film-like member S1 is sucked and held by the suction blower. In this case, the uppermost film-like member S1 is pressed in flatly until the uppermost film-like member S1 is sucked through the suction blower. However, even if it is pressed in flat, when the uppermost film-like member S1 is adsorbed and held, further pressing-in toward the lower side (Z2 side) of the uppermost film-like member S1 is stopped, so it is possible to Prevent scratches as described above.

In addition, after the uppermost film-like member S1 is sucked by the suction plate 221, a moving mechanism (not shown) is operated to raise the suction base 220, and then the uppermost film-like member S1 is transported to another processing site.

(7) Seventh step: lowering of the mounting table 201 (return to the initial position) Next, the control unit 210 actuates the mounting table cylinder 203 and lowers the mounting table 201 to move the mounting table 201 to the initial position. Then, the operations from the first step to the seventh step described above are repeated to sequentially take out the film-shaped member S from the laminate PS.

(About other control actions) However, the operation of dropping the other film-like member S on the first suction unit 20 side and the second suction unit 120 side as described above may also be performed as follows. First, the first step (adsorption and holding of the uppermost film-like member S) similar to the step described in FIG. 6 is performed. The first step has already been described, so its description is omitted.

Next, as an operation having both the second step (separating the uppermost film-like member S1 from the laminated body PS) and the third step (implementation of shaking-off operation), the following eighth to eleventh steps are performed .

(8) Eighth step: Ascending of the adsorption holding portion 30 on one side (X1 side) of the arrangement direction of the first adsorption unit 20 After the first step, the control unit 210 controls the operation of the lift cylinder 62 to raise, for example, the suction holding unit 30 on the side in the arrangement direction (X1 side) among the suction holding units 30 present on the first suction unit 20 side. This state is shown in Fig. 18. Then, the support shaft 41 is inclined, so that the height position of the suction holding portion 30 gradually decreases from one side (X1 side) in the arrangement direction of the suction holding portion 30 to the other side (X2 side). At this time, the suction holding portions 130 present on the second suction unit 120 side are arranged in a state where the height positions are aligned, and therefore, the film-like member S1 that is sucked and held is not sucked and held in a planar manner but on the back side (Y2 side) The state of being attracted and held in a twisted manner.

By performing such an action of twisting the film-like member S1, air easily enters between the film-like member S1 and the other film-like member S that is in close contact therewith, and thus most of the other film-like member S is removed from the film-like member S1 Drop.

(9) Ninth step: the rise of the suction holding portion 30 on the other side (X2 side) of the arrangement direction of the first suction unit 20 Next, the control unit 210 controls the operation of the lift cylinder 62 to raise the suction holding unit 30 located on the other side (X2 side) in the arrangement direction among the suction holding units 30 present on the first suction unit 20 side. This state is shown in Fig. 19. As a result, the entire suction holding portion 30 on the side of the first suction unit 20 rises. At this time, on the side of the first suction unit 20, a gap is formed between the film-like member S1 and the next film-like member S2 being held by suction.

At this time, the film-like member S1 recovers from the twisted state, and the entire back side (Y2 side) is raised. Through the execution of this operation, air also easily enters between the film-shaped member S1 and the other film-shaped member S that is in close contact therewith, and thus most of the other film-shaped member S falls from the film-shaped member S1.

(10) Tenth step: the rise of the suction holding portion 130 on the side (X1 side) of the second suction unit 120 in the arrangement direction Next, the control unit 210 controls the operation of the lift cylinder 162 to raise the suction holding unit 130 on the side in the arrangement direction (X1 side) among the suction holding units 130 present on the second suction unit 120 side. This state is shown in FIG. 20. Then, the support shaft 141 is inclined, so that the height position of the suction holding portion 130 gradually decreases from one side (X1 side) in the arrangement direction of the suction holding portion 130 to the other side (X2 side). At this time, since the plurality of suction holding portions 30 on the side of the first suction unit 20 have risen to the same height, the film-like member S1 that is suctioned and held is not sucked and held in a planar manner, but outside The twisted side (Y1 side) is attracted and held.

By performing such an action of twisting the film-like member S1, air is more likely to enter between the film-like member S1 and the other film-like member S that is in close contact therewith. As a result, most other film-like members S are separated from the film-like member S1 drops.

(11) Eleventh step: the rise of the suction holding portion 130 on the other side (X2 side) of the arrangement direction of the second suction unit 120 Next, the control unit 210 controls the operation of the lift cylinder 162 to raise the suction holding unit 130 located on the other side (X2 side) in the arrangement direction among the suction holding units 130 present on the second suction unit 120 side. This state is shown in Fig. 21. As a result, the entire suction holding portion 130 on the side of the second suction unit 120 rises. In addition, at this time, the suction holding portion 30 on the side of the first suction unit 20 has risen as a whole. Therefore, a gap (space) in a substantially parallel state is formed between the film-shaped member S1 and the next film-shaped member S2 that are adsorbed and held.

At this time, the film-shaped member S1 recovers from the twisted state, and the entire back side (Y2 side) is raised. By performing such an operation, air easily enters between the film-shaped member S1 and the other film-shaped member S that is in close contact therewith, and the other film-shaped member S falls from the film-shaped member S1.

By performing the operations from the eighth step to the eleventh step as described above, air easily enters between the film-shaped member S1 and the other film-shaped member S that is in close contact therewith, and thus, the other film that is attached to the film-shaped member S1 The member S falls from the film member S1.

In addition, after the eleventh step, the fourth step (insertion of the separation plate 71), the fifth step (releasing the suction holding of the uppermost film-like member S1), and the sixth step (using the suction base 220 attracts and holds the uppermost film-like member S1) and the seventh step (the lowering of the stage 201 (return to the initial position)).

In addition, after the above steps, each step for manufacturing a flexible printed circuit board is carried out, thereby manufacturing a flexible printed circuit board as a product.

(About efficacy) The film take-out device 10 configured as above can take out the film-shaped member S used in the manufacture of a flexible printed circuit board. The film take-out device 10 includes an adsorption holding portion 30 that can attract and hold one of the film-like members S on the edge side (First suction member), suction holding portion 130 (second suction member) capable of sucking and holding the other edge portion of the film-like member S, and an elevating mechanism 60 that raises or lowers the suction holding portion 30 (first suction member) (First lifting member), lifting mechanism 160 (second lifting member) that raises or lowers the suction holding portion 130 (second suction member), and controls the lifting mechanism 60 (first lifting member) and the lifting mechanism 160 (second Control unit 210 for the movement of the lifting member).

In addition, the control unit 210 performs a first control in which the operation of the elevating mechanism 60 (first elevating member) and the elevating mechanism 160 (second elevating member) is controlled to utilize the suction holding unit 30 (first suction Member) and the suction holding part 130 (second suction member), from the laminated body PS in which a plurality of film-like members S are stacked, the film-like member S1 stacked on the uppermost layer is sucked and held. After this first control, the control unit 210 performs a second control in which at least one of the lifting mechanism 60 (first lifting member) and the lifting mechanism 160 (second lifting member) is controlled to operate the suction holding section 30 (first One of the suction member) and the suction holding portion 130 (second suction member) is relatively raised or lowered relative to the other, thereby shaking off the other film shape except the film-shaped member that is attracted and held Part S.

Therefore, after passing through the first control, the state in which the uppermost film-like member S1 is sucked and held by the suction holding portion 30 (first suction member) and the suction holding portion 130 (second suction member) is formed, and then through the second control, After the first control, by making any one of the suction holding part 30 (first suction member) and the suction holding part 130 (second suction member) relatively rise or fall relative to the other, air becomes easy Entering between the film-shaped member S that is attracted and held and the other film-shaped member S that is in close contact therewith, most of the other film-shaped member S falls from the film-shaped member S1. Therefore, it is possible to prevent a plurality of film-shaped members S from being taken out at the same time.

In addition, in order to prevent such a situation in which a plurality of film-like members S are taken out at the same time, the film-like members S are taken out manually in the prior art. However, in this embodiment, by using the film taking-out device 10, it can be automatically performed This film-like member S is taken out. Therefore, it is possible to prevent human error in the operation of taking out the film-shaped member S, and by performing the automatic taking out operation, it is possible to improve the production efficiency of the flexible printed circuit board.

In addition, the operation for preventing the simultaneous removal of the plurality of film-like members S is achieved by the relative lifting operation between the suction holding portion 30 (first suction member) and the suction holding portion 130 (second suction member) Therefore, it is possible to form a state where no distortion occurs on the film-shaped member S.

In addition, in the present embodiment, the control unit 210 performs a third control after the above-described first control, and in this third control, controls one of the elevating mechanism 60 (first elevating member) and the elevating mechanism 160 (second elevating member) The operation moves the film-like member S sucked and held by the suction holding section 30 (first suction member) and the suction holding section 130 (second suction member) toward the direction of separation from the laminated body PS. After the control, the second control is performed.

Therefore, even if deformation such as warpage occurs in the film-shaped member S, a space for dropping the other film-shaped member S that is in close contact with the film-shaped member S1 can be secured. In addition, a sufficient space for the relative lifting operation between the suction holding portion 30 (first suction member) and the suction holding portion 130 (second suction member) can be ensured, whereby the film-like member can be adhered to The other film-shaped member S of S1 dropped well.

Furthermore, in this embodiment, the elevating mechanism 60 (first elevating member) includes an elevating cylinder 62 (first elevating member on one side) that raises or lowers one side of the suction holding portion 30 (first suction member) in the longitudinal direction And a lift cylinder 62 (the other side first lift member) that raises or lowers the other side of the suction holding portion 30 (first suction member) in the longitudinal direction. In addition, the elevating mechanism 160 (second elevating member) includes an elevating cylinder 162 (one side second elevating member) that raises or lowers one side of the suction holding portion 130 (second suction member) in the longitudinal direction, and the suction holding portion 130 The lift cylinder 162 (the other side second lift member) that rises or falls on the other side in the longitudinal direction of the (second suction member). In the second control, the control unit 210 controls the operation of the lifting cylinder 62 (the first lifting member on one side) to raise the longitudinal side of the suction holding unit 30 (first suction member), After the operation is started, the operation of the lift cylinder 62 (the other first lift member) is controlled to raise the other side of the suction holding portion 30 (first suction member) in the longitudinal direction, and further, the lift cylinder 162 (one side is controlled) The operation of the second lifting member) raises the longitudinal side of the suction holding portion 130 (second suction member), and after the start of the operation, controls the operation of the lifting cylinder 162 (the second lifting member on the other side) to make the suction The other side in the longitudinal direction of the holding portion 130 (second suction member) rises.

Therefore, the suction holding portion 30 (first suction member) located on one side (X1 side) of the longitudinal direction (X direction) is opposite to the suction holding portion 30 (X2 side) located on the other side (X2 side) of the longitudinal direction (X direction). The first suction member) rises, therefore, as shown in FIG. 18, an action of twisting the film-like member S1 is performed. In addition, the suction holding portion 130 (second suction member) located on one side (X1 side) of the longitudinal direction (X direction) is opposite to the suction holding portion 130 (X2 side) located on the other side (X2 side) of the longitudinal direction (X direction). The second suction member) rises, therefore, as shown in FIG. 20, an action of twisting the film-like member S1 is performed. By performing such an operation, air easily enters between the film-shaped member S1 and the other film-shaped member S that is in close contact therewith, and thus most of the other film-shaped member S falls from the film-shaped member S1. Therefore, it is possible to favorably prevent a plurality of film-shaped members S from being simultaneously taken out.

In addition, in this embodiment, in the second control described above, the operations of the elevating mechanism 60 (first elevating member) and the elevating mechanism 160 (second elevating member) are controlled to form the suction holding portion 30 (first suction member) Either of the suction holding part 130 (second suction member) moves toward the direction of separation from the laminate PS, and the suction holding part 30 (first suction member) and the suction holding part 130 (second suction member) Either of the other does not move, and after the start of the operation, the operation of the elevating mechanism 60 (first elevating member) and the elevating mechanism 160 (second elevating member) is controlled to form the suction holding portion 30 (the first One of the suction member) and the suction holding part 130 (second suction member) in a state where it does not move, and one of the suction holding part 30 (first suction member) and the suction holding part 130 (second suction member) The remaining one moves in a direction separating from the laminate PS.

Therefore, as shown in FIG. 8 or FIG. 13, it becomes any one of the suction holding part 30 (first suction member) and the suction holding part 130 (second suction member), and rises or falls with the other as a fulcrum Therefore, air easily enters between the film-like member S1 and the other film-like member S that is in close contact with it. Thereby, the other film-shaped member S can be dropped well from the uppermost film-shaped member S1, and it is possible to prevent a plurality of film-shaped members S from being taken out simultaneously.

Furthermore, in the present embodiment, the film take-out device 10 includes a separation plate 71 (separation member) that is inserted between adjacent film-like members S to prevent adsorption between these film-like members S, and a separation plate A separating plate driver 74 (moving member) that moves the separating plate 71 (separating member) such that 71 (separating member) is inserted between adjacent film-like members S. In addition, the control section 210 controls the operation of the separation plate driver 74 (moving member), and the control section 210 performs a fourth control after the above-described third control in which the separation plate driver 74 (moving member) is controlled. In operation, the separation plate 71 (separation member) is arranged at a position where the film-like member S1 and the laminate PS held by the suction holding portion 30 (first suction member) and the suction holding portion 130 (second suction member) The position between the uppermost film-like member S2.

Therefore, when the holding of the film-like member S1 sucked and held by the suction holding section 30 and the suction holding section 130 (the first suction member and the second suction member) is released, the film-like member S1 faces the uppermost film-like shape of the laminate PS When the member S2 falls, the separation plate 71 is sandwiched between the film-like member S1 and the film-like member S2. Therefore, it is possible to prevent the film-shaped member S1 and the film-shaped member S2 from being closely contacted again, and the film-shaped member S1 and the film-shaped member S2 can be separated well.

In addition, in the present embodiment, the film take-out device 10 includes an adsorption base 220 that can attract and hold the film-like member S in a planar shape, and can be raised or lowered with respect to the laminate PS. Is controlled by the control unit 210. In addition, after the fourth control described above, the control unit 210 performs a fifth control in which the operation of the suction mechanism 50 (first suction member) and the suction mechanism 150 (second suction member) is controlled to release the suction The holding portion 30 and the suction holding portion 130 (the first suction member and the second suction member) hold the film-like member, and the film-like member S1 is laminated on the laminate PS. In addition, after the fifth control, the control unit 210 performs the following control: lowers the suction base 220, presses the laminate PS (laminate), and controls the operation of the suction base 220 to attract and hold the uppermost film shape of the laminate PS Part S1.

Therefore, as shown in FIG. 17, by performing a downward pressing operation of the stacked body PS by the suction base 220, the stacked body PS is sandwiched between the suction plate 221 and the mounting table 201. Thus, even if warpage occurs in the uppermost film-like member S1, the warping operation can correct the warpage of the uppermost film-like member S1. Therefore, the uppermost film-like member S1 can be attracted and held on the suction base 220 in a planar state. Thereby, in the step after manufacturing the flexible printed circuit board, the position of the film-like member S1 can be accurately positioned.

In addition, in the present embodiment, the suction holding portion 30 and the suction holding portion 130 (first suction member and second suction member) are provided with suction chucks 31 and 131 made of elastic members and formed as wrinkles shape. Therefore, the suction chucks 31 and 131 can easily follow the change of the film-shaped member S, and therefore, even if deformation such as warpage occurs in the film-shaped member S, the deformation can be followed. Therefore, even if the suction chucks 31 and 131 abut on the film-shaped member S, damage to the film-shaped member S can be prevented.

In addition, the method for manufacturing a flexible printed circuit board according to this embodiment includes a suction step in which the operations of the lifting mechanism 60 (first lifting member) and the lifting mechanism 160 (second lifting member) are controlled to thereby By the suction holding part 30 (first suction member) capable of attracting and holding one edge of the film-like member S1 and the suction holding part 130 (second suction member) capable of attracting and holding the other edge of the film-like member S1, The film-like member S1 stacked on the uppermost layer is sucked and held from the laminated body PS; a shake-off step, which is performed after the above-mentioned suction step, in which the lift mechanism 60 (first lift member ) And at least one of the elevating mechanism 160 (second elevating member), so that any one of the suction holding portion 30 (first suction member) and the suction holding portion 130 (second suction member) is relative to any other One rises or falls relatively, thereby shaking off the other film-shaped member S other than the film-shaped member sucked and held, wherein the lifting mechanism 60 (first lifting member) causes the suction holding portion 30 (first suction Member) is raised or lowered, and the lift mechanism 160 (second lift member) raises or lowers the suction holding unit 130 (second suction member).

Therefore, after the suction step is performed, the uppermost film-like member S1 is sucked and held by the suction holding portion 30 (first suction member) and the suction holding portion 130 (second suction member), and then the shake-off step is performed. , So that any one of the suction holding portion 30 (first suction member) and the suction holding portion 130 (second suction member) is relatively raised or lowered relative to the other, so that air easily enters the film-like shape that is sucked and held Between the member S1 and the other film-like member S that is in close contact therewith, most of the other film-like member S is dropped from the film-like member S1. Therefore, it is possible to prevent a plurality of film-shaped members S from being taken out at the same time.

In addition, in order to prevent such a situation in which a plurality of film-like members S are taken out at the same time, the film-like members S are taken out manually in the prior art. However, in this embodiment, by using the film taking-out device 10, it can be automatically performed The removal operation of the film-shaped member S. Therefore, it is possible to prevent human error in the operation of taking out the film-shaped member S, and by performing the automatic taking out operation, it is possible to improve the production efficiency of the flexible printed circuit board.

In addition, the operation for preventing such simultaneous removal of the plurality of film-shaped members S is achieved by the relative lifting operation between the suction holding portion 30 (first suction member) and the suction holding portion 130 (second suction member). Therefore, it is possible to form a state where no distortion occurs on the film-shaped member S.

(Modification) In the above, one embodiment of the present invention has been described, but the present invention can be modified in various ways. This will be explained below.

In the above embodiment, the first suction member corresponds to the suction holding portion 30 and the suction mechanism 50, and the second suction member corresponds to the suction holding portion 130 and the suction mechanism 150. However, the above correspondence may be reversed. That is, the first suction member corresponds to the suction holding portion 130 and the suction mechanism 150, and the second suction member corresponds to the suction holding portion 30 and the suction mechanism 50. Similarly, the first lifting member may correspond to the lifting mechanism 160, and the second lifting member may correspond to the lifting mechanism 60.

In addition, in the above-described embodiment, the suction pad 31 is configured to be wrinkled. However, the suction chuck 31 is not limited to such a configuration. For example, it may be configured such that a suction tube or the like is provided at a predetermined pitch in a rubber tube of a predetermined length.

In addition, the film take-out device 10 of the above-described embodiment may further include other configurations. For example, in order to cope with the fact that the film-like members S are attracted to each other by static electricity, an ion generator (a static elimination blower) may be provided, and by blowing air with a predetermined charge from the ion generator, static electricity may be removed.

In addition, regarding each control operation described above, the next control operation may be started after the end of a certain control operation. However, the next control operation may be started at the same time as the end of a certain control operation, or before the end.

In addition, the film-like member S in the above embodiment may be a single-sided copper foil material in which copper foil is present only on one side of a base material such as a polyimide film, or may be present on both sides of the base material The double-sided copper foil material of the copper foil may also be a multilayer material having multiple layers of copper foil above the double-sided copper foil material. In addition, regarding the film-like member S, in addition to the base material and the copper foil, an adhesive material layer or a mold release film that protects the adhesive material layer may be provided. When such an adhesive material layer or a film for mold release is provided, the thickness of the film-shaped member S is increased as compared with a case where no adhesive material layer or a film for mold release is provided. Therefore, even if warpage occurs in the film-like member S, when the suction plate 221 is lowered and the uppermost film-like member S1 is sucked and held, scratches are less likely to occur.
