Furthermore, on the opposite side of the bending member 183 across the transport path 153, a lead support member 155 that supports the first portion 33a of the bent lead 33 from below is fixed to the upper part of the guide member 154.

When bending the leads 33 of the component 31 using the lead bending device 180 of the comparative example having such a configuration, the bending member 183 is moved forward in the X direction as shown in FIGS. 8(A) and 8(B). Then, the first portion 33a of the lead 33 is bent while pushing it forward in the X direction at the tip of the bending member 183. The width W of the conveyance path 153 is set to be larger than the thickness of the tape body 34. For example, while the width W of the transport path 153 is about 2 mm, the thickness of the tape body 34 is about 1 mm. Therefore, as an external force is applied from the bending member 183 to the first portion 33a of the lead 33, the tape body 34 changes to a posture inclined with respect to the vertical plane (YZ plane) within the conveyance path 153, and the lead The second portion 33b of 33 also changes to an attitude inclined with respect to the vertical direction (Z direction) (that is, an attitude inclined with respect to the YZ plane).

Thereafter, as shown in FIG. 8C, the bending member 183 further moves forward in the X direction, so that the first portion 33a of the lead 33 is placed in a posture along the horizontal direction (XY plane). At this time, the first portion 33a of the lead 33 is supported by the lead support member 155 from below. Further, the second portion 33b of the lead 33 and the tape body 34 remain in an inclined position with respect to the vertical direction.

Thereafter, as shown in FIG. 8(D), the bending member 183 moves rearward in the X direction and separates from the lead 33 of the component 31. At this time, the first portion 33a of the reed 33 that has been pushed down is pushed back by the springback of the reed 33. Therefore, the angle θ1 formed by the first portion 33a with respect to the second portion 33b of the lead 33 is larger than 90 degrees, for example, about 95 degrees. Originally, when it is desired to supply a component 31 having a bending angle of 90 degrees, a problem arises in that it is not sufficient to suppress the height of the mounted component 31.

FIG. 9 shows an enlarged view of the main parts of the lead bending device 80 of the first embodiment, and FIG. 10 shows a schematic diagram of the main parts (viewed toward the rear side in the Y direction).

A lead bending device 80 according to the first embodiment shown in FIGS. 9 and 10 includes a bending member 83 that moves forward and backward in the X direction while being guided by a linear guide 86. The linear guide 86 is arranged so as to be inclined (that is, inclined with respect to the horizontal plane (XY plane)) so as to descend toward the front side in the X direction. Therefore, the bending member 83 is bent, for example, in a direction inclined downward at 5 degrees toward the front side in the X direction (that is, in a direction inclined with respect to a direction perpendicular to the tape body 34 sent along the conveyance path 53). It is set up so that it can be moved. Further, the bending member 83 is provided with a posture regulating member 88 that contacts the second portion 33b of the lead 33 at the bending position P to regulate the posture of the second portion 33b. The posture regulating member 88 has a regulating surface 88a along the vertical direction, and when the regulating surface 88a comes into contact with the second portion 33b of the lead 33, it has the function of regulating the second portion 33b in a posture along the vertical direction. have. Furthermore, a lead support member 55 is provided above the guide member 54 to support the bent first portion 33a of the lead 33 from below.

When the lead bending device 80 of the first embodiment having such a configuration bends the leads 33 of the component 31, the bending member 83 is placed on the front side in the X direction as shown in FIGS. , and bend the first portion 33a of the lead 33 while pushing it forward in the X direction using the tip of the bending member 83. At this time, the bending member 83 is moved in a downwardly inclined direction toward the front side in the X direction.

Thereafter, as shown in FIG. 10C, when the first portion 33a of the lead 33 is pushed down by the bending member 83, the first portion 33a is in a posture along the lower surface of the bending member 83. That is, the posture of the first portion 33a is regulated by the lower surface of the bending member 83 in a posture along a direction inclined downward at 5 degrees toward the front side in the X direction. The lower surface of this bending member 83 is a regulating surface 83a that regulates the posture of the first portion 33a, and the regulating surface 83a is inclined at 5 degrees with respect to the XY plane (that is, inclined with respect to the horizontal plane). Further, the second portion 33b of the lead 33 contacts the regulating surface 88a of the attitude regulating member 88, and is regulated in the vertical direction. Therefore, as shown in FIG. 10C, when the postures of the first portion 33a and the second portion 33b of the lead 33 are regulated, the angle θ2 of the first portion 33a with respect to the second portion 33b is 90 degrees. The angle is smaller than that, for example 85 degrees. In this state, the regulating surface 88a of the posture regulating member 88 is located at a position inside the width W of the conveyance path 53 in the X direction, that is, located inside the guide surface 54a of the opposing guide member 54. , regulates the posture of the second portion 33b. In this way, even if the width W of the conveying path 53 is larger than the thickness of the tape body 34, the provision of the posture regulating member 88 prevents the second portion 33b from moving on the regulating surface 88a. The posture can be regulated to be along the vertical direction. Further, the first portion 33a of the lead 33 is supported by the lead support member 55 from below.

Thereafter, as shown in FIG. 10(D), the bending member 83 and the posture regulating member 88 move rearward in the X direction and separate from the lead 33. At this time, the first portion 33a of the reed 33 that has been pushed down is pushed back by the springback of the reed 33. However, since the angle θ2 formed by the first portion 33a with respect to the second portion 33b was bent to 85 degrees, even when pushed back by springback, the angle θ3 formed between the first portion 33a and the second portion 33b is It can be maintained at about 90 degrees.

(Parts supply method)
In the component mounting apparatus 1 of the first embodiment having such a configuration, a component supply method for supplying the components 31 from the component supply device 5 will be explained using the flowchart shown in FIG. 11.

First, in the component mounting device 1, when the board 3 is carried into the mounting work position of the board transport device 2, the component mounting control device 9 A component supply signal is output from the feeder controller 90 to the feeder controller 90 . This component supply signal is output to the feeder control device 90 of the component supply device 5 that accommodates the component 31 of the specifications to be mounted among the plurality of component supply devices 5.

In the component supply device 5, the operator determines in advance whether or not to perform a lead bending operation on the component 31 to be mounted on the board 3. If it is determined that the lead bending operation is to be performed, the component supply device 5 The on-off valve 87 is operated in advance to an open state. As a result, the control valve V2 and the lead bending cylinder 82 are brought into communication through the first air supply path 89.

As shown in FIG. 11, the feeder control device 90 determines whether to perform a component supply operation (step S1). If the component supply signal from the component mounting control device 9 is not input, it is assumed that no component supply operation is to be performed, and the process is terminated or the device enters a standby state. On the other hand, when the component supply signal is input, the tape feeding device 60 performs a feeding operation of the taping component 30 as a component feeding operation (step S2: tape feeding step). Specifically, the control valve V1 is opened by a control signal from the feeder control device 90, and air from the air supply source is supplied to the tape feeding cylinder 62 through the third air supply path 69. Thereby, the tape feeding mechanism 61 is driven, and the taping component 30 is fed along the conveyance path 53. By the feeding operation of the taping component 30, one component 31 is positioned at the supply position 5a on the conveyance path 53, and another component 31 is positioned at the bending position. Thereafter, the control valve V1 is closed, the air supply is stopped, and the drive of the tape feeding mechanism 61 is stopped.

Next, the lead cutting operation of the component 31 by the lead cutter device 70 (step S3: lead cutting step) and the lead bending operation of the component 31 by the lead bending device 80 (step S4: lead bending step) are performed at the same timing. be done.

The control valve V2 is opened by a control signal from the feeder control device 90, and air from the air supply source is supplied to the reed cutter cylinder 72 through the second air supply path 79. As a result, the lead cutter device 70 is driven to cut the lead 33 of the component 31 located at the supply position 5a.

At the same time, by opening the control valve V2, air from the air supply source is supplied to the lead bending cylinder 82 through the first air supply path 89. Note that the on-off valve 87 is set in an open state in advance by the operator. As a result, the lead bending device 80 is driven, and a lead bending operation is performed on the component 31 located at the bending position P.

Thereafter, the component 31 with the lead 33 cut located at the supply position 5a is held by the mounting head 10, and the component is supplied to the mounting head 10 (step S5).

Thereafter, in the feeder control device 90, it is determined whether or not to perform the next component supply (step S1), and if the component supply is to be performed, operations from steps S2 to S5 are sequentially executed. On the other hand, if parts are not to be supplied, the process is terminated or the process is placed on standby.

In the component supply device 5, when the operator judges in advance that the lead bending operation will not be performed on the component 31 to be mounted on the board 3 (that is, the lead bending process will not be performed), the on-off valve 87 is closed. Operate it. As a result, the supply of air for driving the lead bending cylinder 82 is stopped, and the lead bending operation in step S4 is not performed.

Further, the component supply device 5 is provided with a first sensor 91 that detects the return state of the piston in the lead bending cylinder 82 and a second sensor 92 that detects the return state of the piston in the lead cutter cylinder 72. Since air is supplied to the lead bending cylinder 82 and the lead cutter cylinder 72 through the common control valve V2, the operating states of the pistons are also the same. On the other hand, when the on-off valve 87 is closed and the air supply to the lead bending cylinder 82 is stopped, the operating states of the pistons of the lead bending cylinder 82 and the lead cutter cylinder 72 are different. For example, when the on-off valve 87 is in the closed state, the piston of the lead bending cylinder 82 is maintained in the returned state. On the other hand, in the reed cutter cylinder 72, the return state and the forward state of the piston are repeated by opening and closing the control valve V2. Therefore, if there is a difference between the detection signals of the first sensor 91 and the second sensor 92, the on-off valve 87 is in the closed state and the lead bending operation is not performed. It can be judged based on Furthermore, by outputting this detection signal to the component mounting control device 9, it is possible to determine whether the component mounting control device 9 is in a state where the lead bending operation is not performed. By displaying such a determination result using a display device or the like, the operator may be able to visually confirm whether the on-off valve 87 is in the open/closed state or whether the lead bending operation is being performed.

According to the component supply device 5 of the first embodiment, the bending member 83 moves in a direction inclined with respect to the direction perpendicular to the tape body 34 of the taped component 30 sent along the conveyance path 53. The structure is such that it can be folded. By employing such a configuration, for example, when the first portion 33a of the lead 33 is pushed down by the bending member 83, the angle θ2 formed by the first portion 33a with respect to the second portion 33b is smaller than 90 degrees. , for example, 85 degrees. As a result, even if the bending member 83 separates from the lead 33 and the first portion 33a of the lead 33 is pushed back by about 5 degrees due to springback, the angle θ3 between the first portion 33a and the second portion 33b can be maintained at about 90 degrees. Therefore, in the component supply device 5, the bending process of the lead 33 can be efficiently performed on the taped component 30 holding the lead type component 31 by the tape body 34 at a desired angle.

Further, the bending member 83 is provided with an attitude regulating member 88 . As a result, when the first portion 33a of the lead 33 is pushed down by the bending member 83, the first portion 33a assumes a posture along the lower surface of the bending member 83, and the second portion 33b assumes a posture along the regulating surface 88a of the posture regulating member 88. The object contacts the object and is regulated to a vertical posture. Therefore, when the first portion 33a of the lead 33 is pushed down by the bending member 83, the angle θ2 formed by the first portion 33a with respect to the second portion 33b is an angle smaller than 90 degrees, which is an angle that takes into account return due to springback. , for example, can be maintained at 85 degrees.

Further, the regulating surface 88a of the posture regulating member 88 is located at a position inside the width W of the conveyance path 53 in the X direction, that is, located inside the guide surface 54a of the opposing guide member 54, and the second The posture of the portion 33b is regulated. Therefore, even if the width W of the conveying path 53 is larger than the thickness of the tape body 34, the regulating surface 88a of the posture regulating member 88 maintains the posture of the second portion 33b in the vertical direction. Can be regulated. Therefore, the angle θ2 formed by the first portion 33a with respect to the second portion 33b can be maintained at a desired angle.

Further, an adjustment member 91 is provided at the connection portion between the lead bending cylinder 82 and the cam 84c. Thereby, the position of the bending member 83 in the X direction can be adjusted. Therefore, the position of the bending member 83 and the position of the posture regulating member 88 can be adjusted according to the specifications of the component 31 to be handled, for example, the wire diameter of the lead 33.

Furthermore, a support member 75 is provided at the supply position 5a of the component 31 to support the body portion 32 of the component 31 with the lead 33 bent from below. As a result, when the body portion 32 of the component 31 located at the supply position 5a is held from above by the mounting head 10, the body portion 32 is supported from below by the support member 75, so that the body portion 32 is Escape to the downward side can be suppressed. Therefore, parts 31 can be reliably supplied.

Therefore, it is possible to provide a component supply device 5 and a component mounting device 1 that can efficiently bend the leads 33 for a taped component 30 in which a plurality of radial lead type components 31 are held by the tape body 34. I can do it.

(Embodiment 2)
Next, FIG. 12 shows an enlarged view of the main part of the lead bending device 180 included in the component supply apparatus 205 according to the second embodiment of the present disclosure, and FIG. 13 shows a schematic diagram of the main part. Components that are the same as those of the component supply device 5 of Embodiment 1 are given the same reference numerals and their explanations will be omitted. Hereinafter, differences from Embodiment 1 will be explained.

A lead bending device 280 according to the second embodiment shown in FIGS. 12 and 13 includes a bending member 83 that moves forward and backward in the X direction while being guided by a linear guide 86. Further, the bending member 83 is provided so as to be movable in a downwardly inclined direction toward the front side in the X direction, for example, in a direction inclined at 5 degrees. On the other hand, at the bending position P, the posture regulating member 288 that contacts the second portion 33b of the lead 33 to regulate the posture of the second portion 33b is not provided on the bending member 83 but on the feeder main body 51. Fixed at the top. The posture regulating member 288 has a regulating surface 288a along the vertical direction, and when the regulating surface 288a comes into contact with the second portion 33b of the lead 33, it has the function of regulating the second portion 33b to a posture along the vertical direction. have.

When the lead bending device 280 of the second embodiment having such a configuration bends the leads 33 of the component 31, the bending member 83 is placed on the front side in the X direction as shown in FIGS. , and bend the first portion 33a of the lead 33 while pushing it forward in the X direction using the tip of the bending member 83. At this time, the bending member 83 is moved in a downwardly inclined direction toward the front side in the X direction.

Since the attitude regulating member 288 is fixed to the upper part of the feeder main body 51, at the bending position P, the second portion 33b of the lead 33 is regulated to a posture along the vertical direction by the regulating surface 288a of the attitude regulating member 288. in a state. Therefore, as shown in FIG. 13(B), even in the initial stage of pushing down the lead 33, the first part 33a can be pushed down efficiently while regulating the posture of the second part 33b.

Thereafter, as shown in FIG. 13C, when the first portion 33a of the lead 33 is pushed down by the bending member 83, the first portion 33a assumes a posture along the lower surface of the bending member 83. Further, the second portion 33b of the lead 33 contacts the regulating surface 288a of the attitude regulating member 288, and is regulated in the vertical direction. Therefore, as shown in FIG. 13(C), when the postures of the first portion 33a and the second portion 33b of the lead 33 are regulated, the angle θ2 formed by the first portion 33a with respect to the second portion 33b is 90 degrees. For example, the angle is smaller than 85 degrees. Further, the regulating surfaces 2 and V2a of the posture regulating member 288 are positioned inside the width W of the conveyance path 53 in the X direction, that is, in a state located inside the guide surface 54a of the opposing guide member 54. The posture of the second portion 33b is regulated.

Thereafter, as shown in FIG. 13(D), the bending member 83 moves rearward in the X direction and separates from the lead 33. At this time, the first portion 33a of the reed 33 that has been pushed down is pushed back by the springback of the reed 33. However, since the angle θ2 formed by the first portion 33a with respect to the second portion 33b was bent to 85 degrees, even when pushed back by springback, the angle θ3 formed between the first portion 33a and the second portion 33b is It can be maintained at about 90 degrees.

According to the lead bending device 280 of the component supply device 205 of the second embodiment, the posture regulating member 288 that regulates the posture of the second portion 33b of the lead 33 is fixed to the upper part of the feeder main body 51. With such a configuration as well, the first portion 33a of the lead 33 can be pushed down while the second portion 33b of the lead 33 is restricted by the posture regulating member 288. Therefore, the lead 33 can be stably bent at a desired angle.

In the above embodiments, the case where the lead bending device includes both the bending member and the posture regulating member has been described as an example, but the present disclosure is not limited to such a case. For example, the lead bending device may not include the attitude regulating member but may include a bending member.

Moreover, although the case where the component supply device includes a lead cutter device has been described as an example, it may not include a lead cutter device.

Furthermore, although the springback angle of the reed has been described as being 5 degrees, the springback angle varies depending on the specifications of the reed, and thus may be set to various values depending on the specifications.

Further, the air piping system and control system in the parts supply device are merely examples, and are not limited to the configuration described above, and various known configurations may be adopted.

Note that by appropriately combining any of the various embodiments described above, the effects of each embodiment can be achieved.
