By the way, not only rigid parts such as electric field capacitors that can be mounted by suction nozzles but also flexible plate-shaped members such as flat cables are mounted on the substrate. In this case, the flat plate-shaped member must be formed into an arch shape at the time of supply and mounted on the substrate. If the plate-shaped member is manually formed and then mounted on the substrate, costs such as labor costs increase. In this case, it is possible to form the plate-shaped member by using a robot arm having a plurality of axes and mount it on the substrate, but there is a problem that the introduction cost of the robot arm increases.

The present invention has been made in view of the above points, and one of the objects of the present invention is to provide a forming device and a mounting device capable of forming a plate-shaped member with a simple and inexpensive configuration.

The support portion is a stage that supports the plate-shaped member in a sideways posture, and the deformation mechanism abuts on at least one of both ends of the plate-shaped member. It is a movable block that slides on the stage so that both ends of the plate-shaped member are brought close to each other. According to this configuration, both ends of the plate-shaped member in the horizontal orientation are brought close to each other, so that both ends of the plate-shaped member are formed in the vertical direction. Therefore, the plate-shaped member can be formed with a simple and inexpensive configuration without introducing an expensive robot arm. In addition, the plate-shaped member can be formed by sliding the movable block on the stage.

The forming device includes a movable guide that abuts on side surfaces orthogonal to both ends of the plate-shaped member and slides on the stage so that the direction of the plate-shaped member is aligned with the sliding direction of the movable block. According to this configuration, the direction of the plate-shaped member is uniformly aligned in the sliding direction by contacting the side surface of the plate-shaped member with the movable guide. Therefore, if the orientations of the plate-shaped members are approximately the same on the stage, the orientations of the plate-shaped members are aligned, and it is not necessary to set the plate-shaped members on the stage with the positions and orientations accurately positioned. ..

The forming device of one aspect of the present invention is a forming device that forms so that both ends of the plate-shaped member are oriented vertically, and is a support portion that supports the plate-shaped member in a horizontal posture and both ends of the plate-shaped member. The support portion is a suction pad that sucks the center of the plate-shaped member and supports the plate-shaped member in a sideways posture, and the deformation mechanism is the plate-shaped member. A pair of movable blocks that are in contact with both ends of the member and can be approached so that both ends of the plate-shaped member are brought close to each other, so that both ends of the plate-shaped member are oriented vertically on the facing surfaces of the pair of movable blocks. , The guide surface for guiding both ends of the plate-shaped member is formed. According to this configuration, both ends of the plate-shaped member in the horizontal orientation are brought close to each other, so that both ends of the plate-shaped member are formed in the vertical direction. Therefore, the plate-shaped member can be formed with a simple and inexpensive configuration without introducing an expensive robot arm. Further, the plate-shaped member can be formed by sliding both ends of the plate-shaped member along the guide surface of each movable block due to the approach of the pair of movable blocks.

In the above forming device, the guide surfaces of the pair of movable blocks are curved so that the facing distance increases from the upper side to the lower side. According to this configuration, both ends of the plate-shaped member slide from above to below along the guide surface, so that both ends of the plate-shaped member can be brought closer to each other in the vertical direction.

The forming device of one aspect of the present invention is a forming device that forms so that both ends of the plate-shaped member are oriented vertically, and is a support portion that supports the plate-shaped member in a horizontal posture and both ends of the plate-shaped member. A support base provided with a deformation mechanism that deforms the plate-shaped member so as to bring the plate-shaped member closer to each other, and the support portion attracts the center of the plate-shaped member with a support surface along the forming shape to support the plate-shaped member in a lateral posture. The deformation mechanism is a gripper nozzle that holds the plate-shaped member after forming on a holding surface that follows the forming shape, and the support base and the gripper nozzle are relatively close to each other on the support surface of the support base. It is characterized in that the deformation of the plate-shaped member is guided from the inside and the deformation of the plate-shaped member is guided from the outside by the holding surface of the gripper nozzle. According to this configuration, both ends of the plate-shaped member in the horizontal orientation are brought close to each other, so that both ends of the plate-shaped member are formed in the vertical direction. Therefore, the plate-shaped member can be formed with a simple and inexpensive configuration without introducing an expensive robot arm. In addition, the plate-shaped member can be formed by sandwiching the plate-shaped member between the support surface of the support base and the holding surface of the gripper nozzle and guiding the deformation of the plate-shaped member from the inside and the outside between the support surface and the holding surface. it can. Further, the plate-shaped member can be formed by the gripper nozzle, and the plate-shaped member can be conveyed by the gripper nozzle.

The mounting device of one aspect of the present invention includes the above-mentioned forming device and a gripper nozzle for holding the plate-shaped member after forming on a holding surface along the forming shape, and the plate-shaped member formed by the forming device. Is mounted on a substrate. According to this configuration, the plate-shaped member can be conveyed by the gripper nozzle in the forming shape, and the plate-shaped member can be mounted on the substrate.

In the mounting device, the gripper nozzle has a pair of openable / closable arms, the pair of arms close to form the holding surface along the forming shape, and the pair of arms open to form the plate. The holding surface is separated from the shaped member. According to this configuration, the pair of arms can be closed to hold the plate-shaped member after forming, and the pair of arms can be opened to release the plate-shaped member after forming.

In the mounting device, the gripper nozzle has a pair of fixed arms and a slider that can slide along the pair of arms, and the pair of arms is formed with a holding surface along a forming shape.

Hereinafter, the present embodiment will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of the flat cable of the present embodiment. FIG. 2 is a perspective view of a split substrate connected by a flat cable of the present embodiment. In the following description, a flat cable is illustrated as a plate-shaped member, and a configuration in which a split substrate is connected by a flat cable will be described, but the present invention is not limited to this configuration.

As shown in FIG. 1, the flat cable (plate-shaped member) FC is configured by projecting leads (both ends of the plate-shaped member) L from both ends of the long cable body 5. The cable body 5 is formed in a band shape by covering a plurality of conducting wires with an insulating resin layer. The flat cable FC has flexibility that can be deformed from a flat shape to an arch shape (U-shape) by receiving an external force in the longitudinal direction, and has elasticity that can be restored from the arch shape to a flat shape by the disappearance of the external force. ing. The cable body 5 may be formed by fusing a plurality of conductors covered with a resin film, or may be formed by sandwiching a plurality of conductors between resin plates.

As shown in FIG. 2, the flat cable FC is used for connecting a pair of split substrates W in a formed state, for example. In this case, the flat cable FC is formed in an arch shape so that both ends are oriented vertically, and the lead L (see FIG. 1) at one end of the flat cable FC is inserted into the through hole of one split substrate W, and the other split board W is split. The lead L at the other end of the flat cable FC is inserted into the through hole of the substrate W. Normally, when mounting this flat cable FC, the flat cable FC had to be manually formed into an arch shape and mounted on the substrate W.

In this case, a configuration in which the flat cable FC is mounted on the substrate W by using a robot arm instead of manual work is conceivable. However, since the flat cable FC has elasticity as described above, it is difficult to mount the flat cable FC on the substrate W while maintaining the arch shape after forming. In order to make the robot arm move in the same manner as the manual work, there is a problem that the structure of the robot arm becomes complicated and the introduction cost of the robot arm increases. Therefore, in the present embodiment, instead of the robot arm, a forming device having a simple structure specialized in forming a plate-shaped member such as a flat cable FC is introduced.

Hereinafter, the mounting device of the first embodiment will be described with reference to FIG. FIG. 3 is a perspective view of the mounting device of the first embodiment. It should be noted that FIG. 3 is a simplification for explaining the present embodiment, and it is assumed that the mounting device usually has a configuration. Further, for convenience of explanation, an example in which the flat cable is mounted on another board instead of the split board is illustrated here.

As shown in FIG. 3, the mounting device 1 is configured to mount the flat cable FC supplied from the supply box (supplier) 10 on the substrate W after being formed by the forming device 40. The flat cable FC is conveyed from the supply box 10 toward the forming device 40 by the suction nozzle 20, and the orientation, suction position, etc. of the flat cable FC are imaged by the image pickup device 30 from below during the transfer of the flat cable FC. The flat cable FC after forming is conveyed from the forming device 40 toward the substrate W while maintaining the arch shape by the gripper nozzle 50.

The supply box 10 is formed in a shallow box shape with an open upper part, and a large number of flat cable FCs are housed in bulk. The bottom surface of the supply box 10 is inclined so as to be lowered from one end to the other end, and a supply region 11 for supplying the flat cable FC to the suction nozzle 20 is formed flat on the other end side of the supply box 10. There is. A vibrating device (not shown) is provided below the supply box 10, and when vibration is applied to the supply box 10 by the vibrating device, a large number of flat cable FCs in the supply box 10 descend the slope to the supply area. Move towards 11.

While the flat cable FC arrives at the supply area 11 of the supply box 10, the position and orientation of the flat cable FC are generally positioned by the side surface of the supply box 10 and the like. In the supply region 11 of the supply box 10, the suction nozzle 20 is positioned at an arbitrary position, and the flat cable FC is picked up by the suction nozzle 20. At this time, the suction of the flat cable FC is determined by the fluctuation of the negative pressure of the suction nozzle 20, and if the flat cable FC fails to be sucked, the suction nozzle 20 is positioned at another position in the supply region 11. The pickup is retried.

In the present embodiment, the supply box 10 is illustrated as the feeder, but the feeder may be configured in any way as long as the flat cable FC can be supplied to the suction nozzle 20. For example, the feeder may be a bowl feeder that sequentially conveys the flat cable FC along a spiral conveying path provided on the inner peripheral surface of the bowl by applying vibration to the bowl. Further, the feeder may be a tray feeder that supplies trays in which a plurality of flat cable FCs are arranged. Since the flat cable FCs are aligned in the tray, the suction nozzle 20 can pick up the flat cable FCs in the positioned state.

In the supply box 10, the position and orientation of the flat cable FC are generally positioned, but the flat cable FC is not positioned accurately in the position and orientation. Therefore, the positions and directions of the flat cable FC picked up from the supply box 10 by the suction nozzle 20 are not unified. Therefore, the flat cable FC being conveyed is imaged by the image pickup apparatus 30, and the position and orientation of the flat cable FC are recognized. The position and orientation of the flat cable FC are corrected by the suction nozzle 20 based on the recognition result of the image pickup apparatus 30, and the flat cable FC is set at an accurate position and orientation with respect to the forming apparatus 40.

In the forming device 40, the flat cable FC is formed in an arch shape, and the flat cable FC after forming is picked up by the gripper nozzle 50. The flat cable FC after forming is conveyed on the substrate W by the gripper nozzle 50, and is mounted at a predetermined position on the substrate W by the gripper nozzle 50. At this time, if the arch shape of the flat cable FC is broken, the flat cable FC cannot be mounted on the substrate W, so that accurate forming is required by the forming device 40, and the gripper nozzle 50 is used for conveying while maintaining the forming shape. It has been demanded. Although the description is omitted, the mounting head of the mounting device 1 is provided with a suction nozzle 20 and a gripper nozzle 50, and the mounting head is supported so as to be movable in the horizontal direction.

Here, the forming device and the gripper nozzle will be described in detail with reference to FIGS. 4 to 7. FIG. 4 is an explanatory view of the flat cable after forming according to the first embodiment. FIG. 5 is an explanatory diagram of a forming operation of the forming device of the first embodiment. FIG. 6 is a perspective view of the gripper nozzle of the first embodiment. FIG. 7 is an explanatory diagram of the mounting operation of the gripper nozzle according to the first embodiment.

As shown in FIG. 4A, in order to mount the flat cable FC on the substrate W (see FIG. 3), it is necessary to form the flat cable FC into an arch shape so that both ends are oriented vertically. At this time, the heights of the lead tips at both ends of the flat cable FC and both side surfaces in the width direction of the flat cable FC must be aligned. For example, as shown in FIG. 4B, if the lead tip heights at both ends of the flat cable FC are different or the flat cable FC is twisted, both ends of the flat cable FC may have a through hole formed in the substrate W. The lead L cannot be inserted.

As shown in FIG. 5A, the forming device 40 forms the flat cable FC supported by the stage (support portion) 41 in an arch shape by sliding the movable block (deformation mechanism) 42 on the stage 41. It is configured. A long recess 44 that supports the flat cable FC in a sideways posture is formed on the upper surface of the stage 41. One end of the recess 44 is cut out so that the movable block 42 is arranged, and the other end of the recess 44 is formed with a contact surface 45 that abuts on the lead L of the flat cable FC. Further, a pair of guide surfaces 46 for guiding both side surfaces of the flat cable FC are formed at both ends of the recess 44 in the lateral direction.

A suction port 47 for sucking the center of the flat cable FC is formed on the bottom surface of the recess 44, and the suction port 47 suppresses warpage and bending of the flat cable FC. The suction of the suction port 47 is released at the timing when the flat cable FC starts to be deformed so as not to affect the forming. The movable block 42 is slidably installed on the stage 41 along the elongated recess 44, and slides to substantially the center of the stage 41 while pushing one end of the flat cable FC. As a result, both ends of the flat cable FC are sandwiched between the contact surface 45 of the recess 44 and the movable block 42, and the flat cable FC is formed into an arch shape.

As shown in FIG. 5B, specifically, the flat cable FC is placed in the recess 44 of the stage 41 in a positioned state. At this time, the suction port 47 of the recess 44 suppresses the bending of the flat cable FC, and the flat cable FC is supported so that the lower surface of the flat cable FC does not float from the bottom surface of the recess 44. From this initial state, the movable block 42 slides on the stage 41, and one end of the flat cable FC abuts on the movable block 42 and the other end of the flat cable FC abuts on the contact surface 45 of the recess 44. At this timing, the suction of the suction port 47 is released and the flat cable FC is allowed to be deformed.

As shown in FIG. 5C, when the movable block 42 further slides on the stage 41, one end side of the flat cable FC is pushed toward the other end side, and the flat cable FC begins to be deformed into an arch shape. At this time, since both side surfaces of the flat cable FC are guided by a pair of guide surfaces 46 (see FIG. 5A) of the recesses 44, the flat cable FC is deformed without being displaced in the width direction. Then, the movable block 42 pushes one end of the flat cable FC to substantially the center of the stage 41, so that both ends of the flat cable FC are vertically oriented and formed into an arch shape.

In the present embodiment, the movable block 42 abuts on one end of the flat cable FC and slides on the stage 41 so that both ends of the flat cable FC come close to each other, but the configuration is not limited to this. The movable block 42 may come into contact with at least one of both ends of the flat cable FC. For example, a pair of movable blocks may be installed on the stage 41, and the pair of movable blocks may abut on both ends of the flat cable FC and slide on the stage 41 so that both ends of the flat cable FC are brought close to each other. Further, if the flat cable FC can be formed, the stage 41 may not be provided with the recess 44 or the suction port 47.

As shown in FIGS. 6A and 6B, the gripper nozzle 50 holds the flat cable FC after forming on the holding surface 53 along the forming shape (arch shape), and is a nozzle shaft of a mounting head (not shown). It is detachably attached to. The gripper nozzle 50 is rotated at an arbitrary angle around the vertical axis by a θ-axis motor (not shown), and is moved up and down by an elevating motor (not shown). The gripper nozzle 50 is configured by attaching a pair of open / close type arms 52 that sandwich the arch shape of the flat cable FC to the lower part of the mounting portion 51 that is mounted on the nozzle shaft.

When the pair of arms 52 are closed, the holding surface 53 is formed along the forming shape, and when the pair of arms 52 are opened, the holding surface 53 is separated from the flat cable FC. A guide 54 is provided on the tip end side of each arm 52 so that the flat cable FC does not shift in the width direction. Further, the facing distance L2 (see FIG. 7B) of the holding surfaces 53 in the state where the pair of arms 52 are closed is formed to be narrower than the outer surface distance L1 (see FIG. 7A) on both ends of the flat cable FC after forming. .. Therefore, the flat cable FC is held on the holding surface 53 of the pair of arms 52 by the repulsive force and the frictional resistance to be restored.

Further, when the flat cable FC is held on the holding surfaces 53 of the pair of arms 52, the facing distance L3 (see FIG. 7C) on both ends of the flat cable FC becomes the hole spacing L4 (see FIG. 7C) of the through holes H of the substrate W. ). In the forming device 40, the flat cable FC is formed in an arch shape, but at this point, the opposite distance between both ends of the flat cable FC is slightly wider than the hole distance of the through hole H. That is, the flat cable FC is held by the gripper nozzle 50, so that the flat cable FC is formed into a perfect arch shape mounted on the through hole H of the substrate W.

In the present embodiment, the guide 54 is provided on the tip side of the pair of arms 52. However, if the guide 54 can prevent the position shift of the flat cable FC in the width direction, which position of the gripper nozzle 50 is provided. It may be provided in. For example, the guide 54 may be provided below the mounting portion 51. In this way, the gripper nozzle 50 holds the flat cable FC formed into an arch shape by the forming device 40 (see FIG. 5) and mounts the flat cable FC on the substrate W without breaking the arch shape of the flat cable FC. Therefore, the flat cable FC can be mounted on the substrate W with the same accuracy as in the case of manual forming.

As shown in FIG. 7A, specifically, when the flat cable FC is formed by the forming device 40, the gripper nozzle 50 is brought closer to the flat cable FC from directly above while opening the pair of arms 52. As described above, since the outer surface spacing L1 on both ends of the flat cable FC is wider than the facing spacing L2 (see FIG. 7B) of the holding surfaces 53 when the pair of arms 52 are closed, the pair of arms 52 are opened. The arch shape of the flat cable FC is not broken by bringing it closer in the state. If the rigidity of the flat cable FC is sufficient, the pair of arms 52 may be brought close to the flat cable FC in a closed state.

As shown in FIG. 7B, when the gripper nozzle 50 is lowered to the holding position of the flat cable FC, the pair of arms 52 are closed and the flat cable FC is held so as to be sandwiched from the outside. At this time, since the holding surfaces 53 of the pair of arms 52 are formed following the arch shape of the flat cable FC, the arch shape of the flat cable FC does not collapse. Further, since the facing distance L2 of the pair of arms 52 is narrower than the outer surface distance L1 of the flat cable FC, the pair of arms 52 are held by the gripper nozzle 50 by the repulsive force and the frictional force of the flat cable FC. Further, the guide 54 of the pair of arms 52 prevents the position shift in the width direction.

As shown in FIG. 7C, when the flat cable FC is conveyed to a predetermined position on the substrate W by the gripper nozzle 50, both ends of the flat cable FC are positioned with respect to the through hole H of the substrate W. As described above, when the flat cable FC is held by the pair of arms 52, the facing distance L3 on both ends of the flat cable FC coincides with the hole distance L4 of the through hole H of the substrate W. Therefore, when the gripper nozzle 50 is lowered, the leads L at both ends of the flat cable FC are inserted into the through holes H of the substrate W, and the flat cable FC is mounted on the substrate W.

As shown in FIG. 7D, when the flat cable FC is mounted on the substrate W, the pair of arms 52 are opened and the flat cable FC is released. In this way, the flat cable FC picked up from the forming device 40 (see FIG. 7A) is mounted on the substrate W in an arch shape. In the present embodiment, an example of the open / close type gripper nozzle 50 has been illustrated, but the present invention is not limited to this configuration. The gripper nozzle 50 may have a configuration in which the flat cable FC can be held in an arch shape and mounted on the substrate W, and may be, for example, a plug-in type gripper nozzle 60 (see FIG. 8).

Hereinafter, a plug-in type gripper nozzle will be described as a modified example with reference to FIG. FIG. 8 is an explanatory diagram of the mounting operation of the gripper nozzle of the modified example. The flat cable shall have sufficient rigidity.

As shown in FIG. 8A, the gripper nozzle 60 of the modified example holds the flat cable FC inserted inside the pair of arms 62, and pushes out the flat cable FC from the pair of arms 62 to release the flat cable FC. It is different from the gripper nozzle 50 in the form of. The pair of arms 62 are formed in a substantially L shape, and are attached to the lower part of the mounting portion 61 mounted on the nozzle shaft of the mounting head (not shown). Inside the pair of arms 62, sliders 63 that are slidable along the pair of arms 62 are attached to the mounting portion 61 via a cylinder. The lower surface 64 of the slider 63 is formed in an arch shape along the outer surface shape of the flat cable FC.

The pair of arms 62 and the slider 63 form a holding surface 65 along the forming shape (arch shape), and the slider 63 slides along the pair of arms 62 to push out the flat cable FC from the holding surface 65. Each arm 62 is formed with a guide 66 that guides the slider 63 and the flat cable FC. Further, the facing distance between the holding surfaces 65 of the pair of arms 62 is formed to be slightly narrower than the distance between the outer surfaces on both ends of the flat cable FC after forming. Therefore, the flat cable FC is held on the holding surfaces 65 of the pair of arms 62 by the repulsive force and the frictional resistance to be restored.

Further, when the flat cable FC is held on the holding surfaces 65 of the pair of arms 62, the facing distances on both ends of the flat cable FC match the hole spacing of the through holes H of the substrate W. In the gripper nozzle 60 configured in this way, the flat cable FC is held by the gripper nozzle 60 by pushing the pair of arms 62 against the flat cable FC or pushing the flat cable FC inside the pair of arms 62. Will be done. The flat cable FC is conveyed to the substrate W by the gripper nozzle 60, and the tips of the leads L at both ends of the flat cable FC are inserted into the through holes H of the substrate W.

As shown in FIG. 8B, the slider 63 slides downward along the pair of arms 62 to push out the flat cable FC. As a result, the flat cable FC is released from the gripper nozzle 60, and the leads L at both ends of the flat cable FC are pushed deep into the through holes H of the substrate W. In this way, the flat cable FC picked up from the forming device 40 is mounted on the substrate W in an arch shape. The lower surface 64 of the slider 63 may be formed so that the flat cable FC can be extruded, and may be formed flat, for example.

As described above, the mounting device 1 of the first embodiment has an arch shape so that both ends of the flat cable FC in the horizontal orientation are brought close to each other by the forming device 40 so that both ends of the flat cable FC are oriented vertically. Formed. Further, since the flat cable FC is conveyed in the forming shape by the gripper nozzle 50, the flat cable FC can be mounted on the substrate W without breaking the forming shape. Therefore, the flat cable FC can be formed by a simple and inexpensive configuration without introducing an expensive robot arm.

Next, the mounting device of the second embodiment will be described. The mounting apparatus of the second embodiment is different from the first embodiment only for the forming apparatus. Therefore, the description of the configuration similar to that of the first embodiment will be omitted, and only the forming device will be described. FIG. 9 is an explanatory diagram of the forming operation of the forming device of the second embodiment.

As shown in FIG. 9A, in the forming device 70 of the second embodiment, in addition to the movable block 72 that slides on the stage (support portion) 71 so that both ends of the flat cable FC are brought close to each other, the orientation of the flat cable FC is set. A long movable guide 73 that aligns the movable block (deformation mechanism) 72 in the sliding direction is provided. A recess 74 in which the movable block 72 and the movable guide 73 are housed is formed on the upper surface of the stage 71, and the recess 74 forms an orthogonal slide region of the movable block 72 and the movable guide 73. Further, although the flat cable FC is carried into the recess 74 in a state where the flat cable FC is substantially aligned in position and orientation, a wide area is secured so that the flat cable FC does not protrude.

In this forming device 70, when the flat cable FC is placed in the recess 74, the movable guide 73 slides on the stage 71, and one side surface of the flat cable FC abuts on the movable guide 73 and the other side surface of the flat cable FC. Abuts against the inner surface 75 of the recess 74. As a result, the directions of the flat cable FC are uniformly aligned with the sliding direction of the movable block 42. Further, when the directions of the flat cable FC are matched, the slide of the movable guide 73 is stopped, and the guide surface for guiding both side surfaces of the flat cable FC is formed by the movable guide 73 and the inner side surface 75 of the recess 74.

Next, as shown in FIG. 9B, the movable block 72 slides on the stage 71 in the direction orthogonal to the movable guide 73, and one end of the flat cable FC abuts on the movable block 72 and the other end of the flat cable FC is recessed. It abuts on the inner surface 76 of 74. Further, when the movable block 72 slides on the stage 71, one end side of the flat cable FC is pushed toward the other end side, and the flat cable FC begins to be deformed into an arch shape. At this time, since both side surfaces of the flat cable FC are guided by the movable guide 73 and the inner side surface 75 of the recess 74, the flat cable FC is deformed without being displaced in the width direction.

Then, the movable block 72 slides to the vicinity of one corner of the recess 74 and pushes one end of the flat cable FC so that both ends of the flat cable FC are vertically oriented and formed into a perfect arch shape. In this way, if the directions of the flat cable FC are approximately the same on the stage 71, the directions of the flat cable FC are aligned, so that the flat cable FC is set on the stage 71 in a state where the position and orientation are accurately positioned. There is no need to. Therefore, since it is not necessary to correct the position and orientation of the flat cable FC in the mounting device 1 as shown in FIG. 3, the device configuration can be simplified by omitting the image pickup device 30.

As described above, also in the forming device 70 of the second embodiment, the flat cable FC can be formed by a simple and inexpensive configuration without introducing an expensive robot arm as in the first embodiment. ..

In the second embodiment, the movable block 72 may come into contact with at least one of both ends of the flat cable FC. For example, a pair of movable blocks may be prepared and come into contact with both ends of the flat cable FC. May be good. Further, the movable guide 73 may be brought into contact with at least one of both side surfaces of the flat cable FC, and for example, a pair of movable guides may be prepared and come into contact with both side surfaces of the flat cable FC.

Next, the mounting device of the third embodiment will be described. The mounting device of the third embodiment is different from the first embodiment only for the forming device. Therefore, the description of the configuration similar to that of the first embodiment will be omitted, and only the forming device will be described. FIG. 10 is an explanatory diagram of the forming operation of the forming device according to the third embodiment. In the following description, a flat cable that is warped downward will be described as an example, but a flat cable that is warped upward will also be formed in the same manner.

As shown in FIG. 10A, the forming device 80 of the third embodiment has a flat cable FC supported by a rubber suction pad (support portion) 81 by approaching a pair of movable blocks (deformation mechanism) 82. It is configured to form into an arch shape. The suction pad 81 is communicated with a vacuum source (not shown), sucks the center of the flat cable FC to support the flat cable FC in a sideways posture, and raises and lowers the support position of the flat cable FC (not shown). Is connected to. The pair of movable blocks 82 are arranged so as to face each other with both ends of the flat cable FC interposed therebetween, and are connected to a moving mechanism (not shown) that moves the flat cable FC in the separating direction and the approaching direction.

The facing surfaces of the pair of movable blocks 82 are cut out to form a concave shape, and both ends of the flat cable FC are guided to the concave facing surfaces so that both ends of the flat cable FC approach in the vertical direction due to the approach of the movable block 82. A guide surface 83 is formed. The guide surfaces 83 of the pair of movable blocks 82 are curved in an R shape so that the facing intervals increase from the upper side to the lower side. Therefore, when the pair of movable blocks 82 are brought close to each other and both ends of the flat cable FC are brought into contact with the guide surfaces 83 of the respective movable blocks 82, both ends of the flat cable FC slide along the guide surfaces 83. , The flat cable FC is formed into an arch shape.

Further, since both ends of the flat cable FC are separated from the guide surface 83 when the pair of movable blocks 82 approach a predetermined distance, the flat cable FC detached from the guide surface 83 is pushed above the facing surface of the pair of movable blocks 82. A pressing surface 84 is formed. Further, below the facing surfaces of the pair of movable blocks 82, support portions 85 are provided to support both ends of the flat cable FC detached from the guide surface 83 from below. As described above, in the first half of the forming operation, the forming of the flat cable FC is guided by the guide surface 83, and in the latter half of the forming operation, the forming of the flat cable FC is guided by the pressing surface 84 and the support portion 85.

Specifically, the flat cable FC is sucked and held in a state where the center of the flat cable FC is positioned on the suction pad 81. At this time, although the flat cable FC is warped downward, the pad surface of the rubber suction pad 81 is deformed following the warp of the flat cable FC, so that air leakage does not occur in the suction pad 81. In this initial state, the suction pad 81 is positioned at the descending position, and is positioned at a height at which both ends of the flat cable FC can enter the concave facing surfaces of the pair of movable blocks 82. Further, the pair of movable blocks 82 are close to each other and are positioned near both ends of the flat cable FC.

As shown in FIG. 10B, the suction pad 81 rises from this initial state to the raised position, and both ends of the flat cable FC are positioned near the upper ends of the guide surfaces 83 of the pair of movable blocks 82. Then, the pair of movable blocks 82 abut on both ends of the flat cable FC and approach each other so as to bring both ends of the flat cable FC close to each other. As a result, both ends of the flat cable FC slide from above to below along the guide surface 83, and the flat cable FC begins to deform into an arch shape. At this timing, the suction of the suction pad 81 is released, and the flat cable FC is allowed to be deformed. Further, since both ends of the flat cable FC are pressed from above by the curved guide surfaces 83, the flat cable FC does not come off from the pair of movable blocks 82.

As shown in FIG. 10C, when the pair of movable blocks 82 come closer to each other and both ends of the flat cable FC come off from the guide surfaces 83 of the pair of movable blocks 82, both ends of the flat cable FC are lowered by the support portion 85. Supported by. Then, the flat cable FC detached from the guide surface 83 is pushed by the pressing surfaces 84 of the pair of movable blocks 82, so that both ends of the flat cable FC are vertically oriented and formed into a perfect arch shape. In this way, since the deformation of the flat cable FC is guided by the guide surfaces 83 of the pair of movable blocks 82, the flat cable FC can be appropriately deformed regardless of the direction of warpage.

As described above, in the forming device 80 of the third embodiment, both ends of the flat cable FC slide along the guide surface 83 of each movable block 82 due to the approach of the pair of movable blocks 82, so that the flat cable FC can be formed. Therefore, as in the first embodiment, the flat cable FC can be formed by a simple and inexpensive configuration without introducing an expensive robot arm.

In the third embodiment, the suction pad 81 and the pair of movable blocks 82 may be raised and lowered relative to each other, and the movable block 82 may be raised and lowered with respect to the suction pad 81. And the movable block 82 may be moved at the same time.

Further, in the third embodiment, the guide surfaces 83 of the pair of movable blocks 82 are formed in a curved shape, but the present invention is not limited to this configuration. The guide surface 83 of the movable block 82 may be able to guide both ends of the flat cable FC so that both ends of the flat cable FC are oriented vertically. For example, the guide surfaces 83 of the pair of movable blocks 82 may be formed on slopes in which the facing intervals increase from the upper side to the lower side.

Next, the mounting device of the fourth embodiment will be described. The mounting device of the fourth embodiment is different from the first embodiment only for the forming device. Therefore, the description of the configuration similar to that of the first embodiment will be omitted, and only the forming device will be described. FIG. 11 is a perspective view of the forming device according to the fourth embodiment. FIG. 12 is an explanatory diagram of a forming operation of the forming device according to the fourth embodiment. Since the gripper nozzle of the fourth embodiment has the same structure as the gripper nozzle of the first embodiment, the description thereof will be omitted.

As shown in FIG. 11, the forming device 90 of the fourth embodiment has an arch shape of the flat cable FC by sandwiching the flat cable FC between the gripper nozzle (deformation mechanism) 92 and the support base (support portion) 91. It is configured to form to. The support base 91 attracts the center of the flat cable FC with a support surface 93 along the forming shape to support the flat cable FC in a sideways posture, and raises and lowers the support position of the flat cable FC (not shown). Is connected to. Further, on both sides of the support base 91, a pair of support blocks 94 (see FIG. 12) that support both ends of the flat cable FC from below are provided.

The upper surface of the support surface 93 of the support base 91 is formed flat, and a suction port 95 for sucking and holding the flat cable FC is formed on this flat surface. Further, the support base 91 is provided with a guide 96 that guides the flat cable FC so as not to be displaced in the width direction on a flat upper surface. Both side surfaces of the support surface 93 of the support base 91 are curved along the forming shape like the pair of arms 97 of the gripper nozzle 92. Therefore, when the flat cable FC is sandwiched between the support base 91 and the gripper nozzle 92, the flat cable FC is formed by the support surface 93 of the support base 91 and the holding surface 98 of the gripper nozzle 92.

At this time, the space between both sides of the support surface 93 of the support base 91 (see FIG. 12A) is narrower than the space between the inner surfaces L6 (see FIG. 12B) on both ends of the flat cable FC after forming. On the other hand, the facing distance L7 (see FIG. 12A) of the holding surfaces 98 with the pair of arms 97 of the gripper nozzle 92 closed is narrower than the outer surface distance L8 (see FIG. 12B) on both ends of the flat cable FC after forming. It is formed. Therefore, when the flat cable FC is picked up, both side surfaces of the support base 91 do not get caught in the flat cable FC, and the holding surfaces 98 of the pair of arms 97 are affected by the repulsive force and the frictional resistance that the flat cable FC tries to restore. Be retained.

As shown in FIG. 12A, specifically, the flat cable FC is sucked and held in a state where the center of the flat cable FC is positioned on the support base 91, and both ends of the flat cable FC are supported on the support block 94 on the side of the support base 91. Will be done. At this time, the gripper nozzle 92 is positioned directly above the support base 91 with the pair of arms 97 closed. The support base 91 is raised from this initial state, and the flat cable FC supported by the support base 91 is pressed against the pair of arms 97 of the gripper nozzle 92. As a result, the flat cable FC begins to deform into an arch shape following the holding surface 98 of the gripper nozzle 92. At this timing, the suction of the suction port 95 is released and the flat cable FC is allowed to be deformed.

As shown in FIG. 12B, when the support base 91 and the gripper nozzle 92 approach each other, the deformation of the flat cable FC is guided from the inside by the support surface 93 (see FIG. 11) of the support base 91, and the gripper nozzle 92 The deformation of the flat cable FC is guided from the outside by the holding surface 98 of the flat cable FC. Then, when the support base 91 completely enters the inside of the pair of arms 97, both ends of the flat cable FC are vertically oriented and formed into a perfect arch shape. In this way, the flat cable FC is deformed by the gripper nozzle 92, and at the same time, the flat cable FC is held by the gripper nozzle 92.

As described above, in the forming device 90 of the fourth embodiment, the flat cable FC is sandwiched between the support surface 93 of the support base 91 and the holding surface 98 of the gripper nozzle 92, and the support surface 93 and the holding surface 98 are flat. By guiding the deformation of the cable FC from the inside and the outside, the flat cable FC can be formed. Further, the gripper nozzle 92 can form the flat cable FC, and at the same time, the gripper nozzle 92 can convey the flat cable FC. Therefore, as in the first embodiment, the flat cable FC can be formed by a simple and inexpensive configuration without introducing an expensive robot arm.

In the fourth embodiment, the support base 91 and the gripper nozzle 92 may be relatively close to each other, and the gripper nozzle 92 may be brought close to the support base 91, or the support base 91 and the gripper may be brought close to each other. The nozzles 92 may be moved at the same time to bring them closer to each other. When the gripper nozzle 92 is brought close to the support base 91, the pair of support blocks 94 are retracted to a position where they do not interfere with the flat cable FC during forming.

Further, in the fourth embodiment, the guides 96 and 99 are provided on both the support base 91 and the gripper nozzle 92, but the configuration is not limited to this. Guides may be provided only on one of the support base 91 and the gripper nozzle 92.
