The present disclosure is not limited to the specific configurations of the following embodiments, and configurations based on similar technical ideas are included in the present disclosure.

(Embodiment)
1 is a plan view of a component mounting apparatus 1 having a component supplying device 5 mounted thereon according to an embodiment of the present disclosure, and FIG. 2 is a side view of the component mounting apparatus 1.

In FIG. 1, a board transport device 2 is installed in the center of the base 1a. The board transport device 2 transports the board 3 carried in from the upstream side in the X direction, and positions and holds it at the mounting position by the mounting head 10. The board transport device 2 transports the board 3 downstream in the X direction after component mounting work has been completed. The board transport device 2 has the function of a transport device that transports the board 3, and the function of a board holding device that positions and holds the board 3. Component supply units 4 are installed on both sides (Y direction) of the board transport device 2.

Here, the X direction and the Y direction are two axial directions that are mutually perpendicular in a horizontal plane. The X direction (left-right direction in FIG. 1) indicates the board transport direction, and the Y direction indicates the direction from the outside of the component supply unit 4 toward the board transport device 2 (component supply direction). The Z direction is a direction perpendicular to the X direction and the Y direction, and is the up-down direction when the component mounting device 1 is installed on a horizontal plane.

The component supply section 4 is equipped with multiple component supply devices 5 arranged in parallel in the X direction. The component supply device 5 is a device that pitch-feeds a tape-taped component string, which is a component with leads (lead-type components) and has the leads of multiple radial lead-type components held by a tape body, in a direction (Y direction) from the outside of the component supply section 4 toward the board transport device 2 to supply the components to a pickup position 5a. Here, the pickup position 5a is a position on the transport path of the tape-taped component string where the mounting head 10 picks up the components, and is a "supply position" where the components are supplied from the component supply device 5 to the mounting head 10.

As shown in FIG. 1, a Y-axis beam 8 equipped with a linear drive mechanism is installed along the Y direction at one end in the X direction of the top surface of the base 1a. Two X-axis beams 9 similarly equipped with linear drive mechanisms are connected to the Y-axis beam 8 so that they can move freely in the Y direction. Each X-axis beam 9 is equipped with a mounting head 10 so that it can move freely in the X direction. The mounting head 10 is equipped with multiple component holding units 11 (three in this example). The Y-axis beam 8 and the X-axis beam 9 form a head moving mechanism 12 that moves the mounting head 10 horizontally (X direction, Y direction).

As shown in FIG. 2, the component supplying device 5 is mounted on the base 1a with the feeder side connection portion 5b of the component supplying device 5 connected to the equipment side connection portion 1b of the base 1a. By connecting the feeder side connection portion 5b to the equipment side connection portion 1b, the component supplying device 5 is electrically connected to the component mounting device 1. At the lower end of each component holding unit 11, a component holding portion 11a is provided that clamps and holds the components supplied by the component supplying device 5.

(Parts mounting operation)
In the component mounting operation, the mounting head 10 is moved by the head moving mechanism 12 to above the component supply device 5, and the component 31 supplied to the pick-up position 5a of the component supply device 5 is held by the component holder 11a and picked up (arrow a). The mounting head 10 holding the component 31 is moved by the head moving mechanism 12 to above the board 3 held at the mounting operation position of the board transport device 2, and the leads of the component 31 are inserted into the through holes 3a formed in the board 3 to mount the component on the board 3 (arrow b).

As shown in FIG. 1, a component recognition camera 13 is installed between the component supply unit 4 and the board transport device 2. When the mounting head 10, which has taken out a component 31 from the component supply device 5, moves above the component recognition camera 13, the component recognition camera 13 captures and recognizes the component 31 held by the mounting head 10. The joining plate 10a to which the mounting head 10 is attached is provided with a board recognition camera 14 that is located on the underside of the X-axis beam 9 and moves integrally with the mounting head 10.

As the mounting head 10 moves, the board recognition camera 14 moves above the board 3 positioned on the board transport device 2 and captures an image of a board mark (not shown) on the board 3 to recognize the position of the board 3. The board recognition camera 14 also captures an image of a through hole 3a formed in the board 3 to recognize the position of the through hole 3a. When the mounting head 10 mounts the component 31 on the board 3, the mounting position is corrected taking into account the recognition results of the component by the component recognition camera 13 and the recognition results of the board 3 and through hole 3a by the board recognition camera 14.

(Taping parts series)
FIG. 3 is a perspective view showing the appearance of a series of taped components 30 handled by the component supply device 5. As shown in FIG.

As shown in FIG. 3, the taped component series 30 is a component assembly in which, as lead-type components, for example, multiple radial lead-type components 31 are held by a tape body 34. The radial lead-type components 31 (hereinafter, sometimes simply referred to as "component 31" or "radial component 31") have a body 32, which is a functional part of an electronic component, and two leads 33, which are connection terminals that extend in one direction, for example downward, from the body 32. The multiple components 31 are arranged in the same position with the leads 33 facing downward and at an equal pitch P, and the lower ends of the leads 33 are held by the tape body 34. The tape body 34 extends along the arrangement direction of the components 31, and is provided with feed holes 34a at regular intervals. The feed holes 34a are engaged with the feed claws of the tape feed section of the component supply device 5 and are used for the feed operation of the taped component series 30.

A lead-type component may be any component having a lead extending from a body, and in this embodiment, a case where the lead-type component is a radial lead-type component is described as an example. Also, a case where multiple lead-type components are held in the taping component series is described as an example, but it is sufficient that at least one lead-type component is held in the taping component series.

(Parts supply device)
Fig. 4 shows an overall perspective view of the component supply device 5. In Fig. 4, in order to easily understand the internal configuration of the component supply device 5, the internal structure is shown with exterior members such as an exterior cover removed. Also, detailed structures such as air piping and electrical wiring are not shown.

As shown in FIG. 4, the component supply device 5 is detachably mounted on the component supply section 4 (not shown) of the component mounting device 1, with the forward side in the Y direction (+Y direction side) being the mounting operation position side of the component mounting device 1.

The part supply device 5 shown in FIG. 4 has a feeder main body 51.

The feeder body 51 has the function of pitch-feeding the taped component series 30 in the conveying direction Y1 (forward in the Y direction) and sequentially supplying the components 31 of the taped component series 30 to the pickup position 5a. The taped component series 30 are stored in a storage section (not shown) in a zigzag or reel state and are supplied to the feeder body 51.

The feeder body 51 includes a tape feed section 60, a lead cutting section 70, a tape cutting section 80, and a used tape guide section 90.

A transport path 53 for the taping component series 30 is provided in the Y direction at the top of the feeder main body 51, and the pickup position 5a is located at the front end of the transport path 53 in the Y direction (downstream of the transport direction Y1).

The tape feed unit 60 includes a tape feed mechanism 61 and a tape feed drive source 62 that drives the tape feed mechanism 61. Various known mechanisms may be used as the tape feed mechanism 61. In this embodiment, the tape feed mechanism 61 includes, for example, a feed claw (not shown) that engages with a plurality of feed holes 34a provided in the tape body 34 of the taping component series 30, and a drive mechanism (not shown) that drives the feed claw forward and backward. Note that such a drive mechanism may be composed of multiple parts, and may be, for example, a cam/cam follower mechanism.

The tape feed drive source 62 is composed of an air cylinder and is connected to the drive mechanism of the tape feed mechanism 61. When the air cylinder is driven, the tape feed drive source 62 drives the drive mechanism, and the feed claw is driven forward and backward, thereby feeding the tape component series 30 along the transport path 53. When the feed claw moves in the forward direction relative to the transport path 53, the feed claw and the feed hole 34a are engaged, and when the feed claw moves in the backward direction, the engagement between the two is released.

The lead cutting unit 70 is a member/mechanism for cutting the leads 33 of the component 31 at the pick-up position 5a. By cutting the leads 33 of the component 31 at the pick-up position 5a, the component 31 can be supplied to the mounting head 10 with the length of the leads 33 adjusted to the desired length.

The tape cutting unit 80 is a member/mechanism for cutting the used tape body 34 from the taping component series 30 after the leads 33 have been cut by the lead cutting unit 70. Cutting the used tape body 34 makes it easier to dispose of the tape body 34 and also reduces the occurrence of errors by suppressing tape clogging.

The used tape guide section 90 is a member for guiding the used tape body 34 cut by the tape cutting section 80 to the outside of the feeder body section 51. This makes it easier to dispose of the used tape body 34 and prevents the tape from clogging.

As shown in FIG. 4, the lead cutting unit 70 is provided at the pickup position 5a, the tape cutting unit 80 is provided downstream of the lead cutting unit 70, and the used tape guide unit 90 is provided downstream of the tape cutting unit 80.

The component supply device 5 of this embodiment includes a cutting drive source 71 and a cutting drive mechanism 72 as a common drive unit for driving the lead cutting unit 70 and the tape cutting unit 80.

The cutting drive source 71 is a drive source for commonly driving the lead cutting unit 70 and the tape cutting unit 80, and is composed of, for example, an air cylinder. The cutting drive source 71 is connected to the cutting drive mechanism 72.

The cutting drive mechanism 72 is a mechanism for moving the movable parts of the lead cutting unit 70 and the tape cutting unit 80, and is connected to each of the movable parts. The cutting drive mechanism 72 is, for example, configured as a cam/cam follower mechanism, but any configuration may be used as long as it is capable of driving the lead cutting unit 70 and the tape cutting unit 80, respectively.

In the component supply device 5 of this embodiment, the lead cutting unit 70 and the tape cutting unit 80 are driven by a common drive unit, which increases processing functions while suppressing cost increases.

The detailed configurations of the lead cutting unit 70, tape cutting unit 80, and used tape guide unit 90 are described below with reference to Figures 5 to 10.

Figures 5 and 6 are enlarged perspective views showing the periphery of the pickup position 5a. Figures 7A and 7B are enlarged perspective views for explaining the operation of the lead cutting section 70 and the tape cutting section 80, Figures 8A and 8B are front views for explaining the same operations, and Figures 9A and 9B are enlarged plan views for explaining the same operations. Figure 10 is a plan view for explaining the dimensional relationship between the lead cutting section 70, the tape cutting section 80, and the used tape guide section 90.

As shown in Figures 5 and 6, in the component supply device 5 of this embodiment, the lead cutting unit 70 and the tape cutting unit 80 are configured as an integral unit. In particular, the movable parts (movable guides 73, 81) of the lead cutting unit 70 and the tape cutting unit 80 are configured as an integral unit, and move back and forth as an integral unit between the retracted position shown in Figures 7A, 8A, and 9A and the operating position shown in Figures 7B, 8B, and 9B.

Figures 5 and 6 show the lead cutting section 70 and tape cutting section 80 in the retracted position. In Figures 5 to 10, the component 31 at the pick-up position 5a is appropriately referred to as "component 31A," and the component 31 immediately before the pick-up position 5a is appropriately referred to as "component 31B."

As shown in Figures 5 and 6, the lead cutting section 70 includes a first movable guide 73 and a first fixed guide 74.

The first movable guide 73 is a movable part of the lead cutting section 70, and is driven by the cutting drive source 71 and cutting drive mechanism 72 described above. In this embodiment, the first movable guide 73 is driven to rotate in a rotation direction R about a rotation axis Ax extending along the conveying direction Y1 of the part 31. The linear driving force of the cutting drive source 71 is converted into a rotational driving force and transmitted via the cutting drive mechanism 72.

The first fixed guide 74 is a fixed part of the lead cutting section 70, and is provided in a position opposite the first movable guide 73 across the conveying path 53 and the component 31A. The first fixed guide 74 does not have a moving function, and is fixedly provided to the feeder main body 51.

The tape cutting section 80 includes a second movable guide 81 and a second fixed guide 82.

The second movable guide 81 is a movable part of the tape cutting section 80, and is driven by the cutting drive source 71 and cutting drive mechanism 72 described above. In this embodiment, the second movable guide 81 is driven to rotate in the rotation direction R around the rotation axis Ax shared with the first movable guide 73.

The second fixed guide 82 is a fixed part of the tape cutting section 80, and is provided at a position opposite the second movable guide 81 across the transport path 53 and the tape body 34. The second fixed guide 82 does not have a moving function, and is fixedly provided to the feeder body section 51.

The first movable guide 73 and the second movable guide 81 described above are integrally configured and move integrally in a first rotation direction R1 toward the retracted position as shown in Figures 7A, 8A, and 9A, and move integrally in a second rotation direction R2 toward the operating position as shown in Figures 7B, 8B, and 9B.

The first movable guide 73 and the second movable guide 81 rotate integrally around a common rotation axis Ax, so the amount of rotation (amount of movement) according to the distance from the rotation axis Ax is the same.

The first fixed guide 74 is provided independently of the first movable guide 73, not integral with it, and the second fixed guide 82 is provided independently of the second movable guide 81, not integral with it.

As shown in Figures 5 and 6, the component supply device 5 further includes a connecting block 100 and a cover member 102.

The connecting block 100 is a block for integrally connecting the first movable guide 73 and the second movable guide 81. The connecting block 100 may be composed of one or more blocks.

The cover member 102 shown in Figures 5 and 6 is a member for covering the gap between the first movable guide 73 and the first fixed guide 74 in the lead cutting section 70. For simplification, the cover member 102 is not shown in Figures 7A to 10. The cover member 102 is provided above the range of movement of the cutting edge portion 75 (Figure 7A, etc.) of the first movable guide 73 at the pick-up position 5a. By providing the cover member 102, it is possible to improve safety by making it more difficult for a person's fingers to get into the gap between the first movable guide 73 and the first fixed guide 74.

In this embodiment, the cover member 102 is fixedly attached to the feeder main body 51 and is positioned below the body 32 of the part 31A at the pickup position 5a. The body 32 of the part 31A is supported on both sides by the cover member 102 and the first fixed guide 74, preventing the part 31A from falling over at the pickup position 5a.

As shown in Figures 5 and 6, the used tape guide section 90 is provided downstream of the tape cutting section 80 so as to receive the used tape body 34A. The used tape guide section 90 is fixed to the feeder body section 51 at a position that does not interfere with the operation of the lead cutting section 70 and the tape cutting section 80. The used tape guide section 90 may be detachable.

As shown in Figures 7A, 8A, 9A, etc., the first movable guide 73 has a cutting edge portion 75, and the first fixed guide 74 has a cutting edge portion 76. The cutting edges 75 and 76 are each a portion having a sharp shape for cutting the leads 33 of the component 31A.

In the retracted position shown in Figures 7A, 8A, and 9A, the blade tips 75, 76 are spaced apart in a direction (X direction) intersecting the transport direction Y1 to form a gap. In the operating position shown in Figures 7B, 8B, and 9B, the blade tips 75, 76 are spaced apart slightly in the height direction (Z direction) and the blade tip 75 of the first movable guide 73 advances inside the first fixed guide 74 to a position where the first movable guide 73 and the first fixed guide 74 overlap in the height direction. This allows the leads 33 of the component 31A to be clamped and cut.

As shown in Figures 7A, 8A, 9A, etc., the second movable guide 81 has a cutting edge portion 84, and the second fixed guide 82 has a cutting edge portion 85. The cutting edges 84 and 85 are each sharp portions for cutting the tape body 34 from the taping component series 30.

In the retracted position shown in Figures 7A, 8A, and 9A, the blade tips 84, 85 are spaced apart in a direction (X direction) intersecting the transport direction Y1 to form a gap. In the operating position shown in Figures 7B, 8B, and 9B, the blade tips 84, 85 are spaced apart slightly in the transport direction Y1, and the blade tip 84 of the second movable guide 81 advances inside the second fixed guide 82 to a position where the second movable guide 81 and the second fixed guide 82 overlap in the transport direction Y1. This allows the tape body 34 to be clamped and cut.

The specifications of the cutting edges 75, 76 and cutting edges 84, 85 vary depending on the shape and dimensions of the lead 33 or tape body 34 to be cut.

Specifically, the direction in which the blade tips 75, 76 extend is different from the direction in which the blade tips 84, 85 extend. The blade tips 75, 76 each extend along the conveyance direction Y1 so as to cut two leads 33 that are separated in the conveyance direction Y1. The blade tips 84, 85 each extend along the height direction (Z direction) of the tape body 34 to be cut, and intersect with the direction in which the blade tips 75, 76 extend.

The area that needs to be cut is wider in the tape body 34 than in the lead 33, so as shown in Figures 7A and 7B, the thickness of the blade tips 84, 85 for cutting the tape body 34 is relatively greater than the thickness of the blade tips 75, 76 for cutting the lead 33.

In order to cut the tape body 34 with a wide cutting area, the blade tip 84 is configured to enter further back (towards the fixed guide) than the blade tip 75 in the operating positions shown in Figs. 7B, 8B, and 9B. For this reason, in the retracted positions shown in Figs. 7A, 8A, and 9A, the distance of the gap between the second movable guide 81 and the second fixed guide 82 is made smaller than the distance of the gap between the first movable guide 73 and the first fixed guide 74. By setting the distance in this way, when the first movable guide 73 and the second movable guide 81 have the same movement amount, the amount of entry of the blade tip 84 can be made relatively larger than the amount of entry of the blade tip 75, and the cutting accuracy of the tape body 34 with a wide cutting area can be improved.

In response to the relatively wide gap between the first movable guide 73 and the first fixed guide 74, a cover member 102 is provided above the operating range of the cutting edge portion 75 of the first movable guide 73, as shown in Figures 5 and 6. This makes it difficult for a person's fingers to get into the gap, improving safety. Note that, because the gap between the second movable guide 81 and the second fixed guide 82 is relatively small, no cover member is provided to cover the gap.

As shown in Figures 7A and 8A, the second fixed guide 82 has a recess 83 on the surface that comes into contact with the second movable guide 81. Because the overlapping area between the second movable guide 81 and the second fixed guide 82 is relatively large, providing the recess 83 reduces the frictional resistance between the surfaces of the second movable guide 81 and the second fixed guide 82, thereby improving the cutting accuracy of the tape body 34.

As shown in Figures 8A and 8B, the used tape guide section 90 has a guide bottom wall 92 and a pair of guide side walls 94. The guide bottom wall 92 and the guide side walls 94 are walls for guiding the used tape body 34A and the lead 33A (Figure 8B) to the outside of the feeder body section 51. The guide bottom wall 92 and the pair of guide side walls 94 form a tape guide passage 96.

The guide bottom wall 92 is inclined diagonally downward so that the used tape body 34A and lead 33A slide under their own weight. In this embodiment, the guide bottom wall 92 and guide side walls 94 are polished by means of buffing or the like, which promotes the sliding movement of the tape body 34A.

The width of the tape guide passage 96 is set wide enough to accommodate the tape body 34A and the leads 33A. When the tape body 34A and the leads 33A reach the tape guide passage 96, they cannot stand on their own on the guide bottom wall 92, so they fall to the side and slide under their own weight. This prevents the tape from jamming in the tape guide passage 96.

As shown in FIG. 8A, when viewed along the transport direction Y1, the center C1 of the width of the used tape guide section 90 is offset from the center C2 of the width of the transport path 53. This arrangement makes it easier to control the direction in which the used tape body 34A discharged from the transport path 53 falls in one direction.

In particular, in this embodiment, center C1 is offset toward the movable guide side (arrow X1) from center C2. This makes it easier for the tape body 34A to be positioned on the fixed side (arrow X2) and the lead 33A to be positioned on the movable side (arrow X1), as shown in FIG. 8B, which facilitates the ejection of used tape.

Next, the dimensional relationships will be explained using Figure 10.

In the retracted position shown in FIG. 10, the gap between the cutting edge 75 and the cutting edge 76 has a length D1. The gap between the cutting edge 84 and the cutting edge 85 has a length D2. In this embodiment, D1>D2. As a result, in a configuration in which the movement amounts of the movable guides 73 and 81 are the same, the penetration amount of the cutting edge 84 can be made relatively larger than the penetration amount of the cutting edge 75, thereby improving the cutting accuracy of the tape body 34, which has a wide cutting area.

The distance between the cutting edge 75 and the cutting edge 84 in the conveying direction Y1 is a length D3. In this embodiment, D3>P (Figure 3). By making the length D3 shorter than the pitch P between the components 31 in the taped component series 30, the cutting position of the leads 33 and the cutting position of the tape body 34 can be brought closer together. This allows the component supply device 5 to be made smaller.

The total height of the used tape body 34A and the leads 33A combined is length D4. The width of the tape guide passage 96 in the used tape guide section 90 is length D5. In this embodiment, D5>D4. By making the width of the used tape guide section 90 longer, the used tape body 34A and the leads 33A can be made to easily fall over, preventing tape jams.

In this embodiment, the width of the transport path 53 is length D6, where D5>D4>D6.

Figure 11 is a block diagram showing the control system of the component mounting device 1, including the component supply device 5.

As shown in FIG. 11, the component mounting device 1 is equipped with a component mounting control device 103 that controls the operation of each device equipped in the component mounting device 1 to control the component mounting operation. The component mounting control device 103 has a function of controlling the operation of each device based on a component mounting program, an operation sequence, information on the components to be mounted, board information, etc. stored in a memory unit, etc. The component supply device 5 is equipped with a feeder control device 104 that controls the operation of the tape feed unit 60, the lead cutting unit 70, and the tape cutting unit 80. The feeder control device 104 is connected to a tape feed drive source 62 for driving the tape feed unit 60 and a cutting drive source 71 for driving the lead cutting unit 70 and the tape cutting unit 80.

The component mounting control device 103 and the feeder control device 104 are electrically connected, and control signals and the like from the component mounting control device 103 are input to the feeder control device 104, and the feeder control device 104 performs control based on the input control signals. In addition, operation information from each device of the component supply device 5 is input to the feeder control device 104, and the operation information is output from the feeder control device 104 to the component mounting control device 103.

The method of supplying components 31 from the component supply device 5 to the mounting head 10 and mounting them on the board 3 in the component mounting device 1 having the above configuration will be explained using the flowchart shown in Figure 12.

First, in the component mounting device 1, when the board 3 is carried into the mounting operation position of the board transport device 2, a component supply signal is output from the component mounting control device 103 to the feeder control device 104 based on the sequence or component information associated with the mounting operation of the components 31 on the board 3. This component supply signal is output to the feeder control device 104 of the component supply device 5 that contains the components 31 with the specifications to be mounted among the multiple component supply devices 5.

As shown in FIG. 12, the feeder control device 104 determines whether or not to perform a part supply operation (S1).

If a component supply signal is not input from the component mounting control device 103, it is assumed that a component supply operation will not be performed (NO in S1), and the process is terminated or the system goes into a standby state. On the other hand, if a component supply signal is input, it is assumed that a component supply operation will be performed (YES in S1), and the tape feed unit 60 feeds the taped component train 30 (S2).

In step S2, air is supplied to the tape feed drive source 62 to drive the tape feed mechanism 61, and the taped component series 30 is fed along the transport path 53. The feed operation of the taped component series 30 positions one component 31A at the pickup position 5a on the transport path 53.

Next, while the mounting head 10 is holding the body 32 of the component 31A, the lead cutting unit 70 performs a lead cutting operation (S3) of the component 31 and the tape cutting unit 80 performs a tape cutting operation (S4) of the tape body 34 at the same time.

In steps S3 and S4, air is supplied to the cutting drive source 71 to drive the cutting drive mechanism 72, and the first movable guide 73 of the lead cutting unit 70 and the second movable guide 81 of the tape cutting unit 80 are driven integrally. The movable guides 73 and 81, which are in the retracted positions shown in Figures 7A, 8A, and 9A, are rotated in the second rotation direction R2 as shown in Figures 7B, 8B, and 9B, so that the first movable guide 73 and the first fixed guide 74 cut the leads 33 of the component 31 (S3), and the second movable guide 81 and the second fixed guide 82 cut the tape body 34 (S4).

Then, by switching the direction of the air supply to the cutting drive source 71, the movable guides 73 and 81 in the operating position are rotated in the first rotation direction R1 as shown in Figures 7A, 8A, and 9A and return to the retracted position.

The used tape body 34A cut in step S4 is discharged outside the feeder body 51 by the used tape guide 90 and discarded. The used tape guide 90 does not use power, but slides by the weight of the tape body 34A and the leads 33A, which can reduce costs compared to when power is used.

Then, the component 31A with the cut leads 33 located at the pickup position 5a is picked up by the mounting head 10 and the component is supplied to the mounting head 10 (S5).

Then, the feeder control device 104 determines whether or not to supply the next part (S1), and if a part is to be supplied (YES in S1), the operations of steps S2 to S5 are executed in sequence. On the other hand, if a part is not to be supplied (NO in S1), the process is terminated or the device goes into a standby state.

By executing the process shown in FIG. 12, the component supply device 5 supplies the components 31, the mounting head 10 picks up the components 31, and the mounting head 10 mounts the components 31 on the board 3 in succession, so that the components 31 included in the taping component series 30 can be inserted sequentially onto the board 3.

According to the component supply device 5 having the above configuration and functions, a lead cutting unit 70 and a tape cutting unit 80 are provided to implement multiple processing functions, and the first movable guide 73 of the lead cutting unit 70 and the second movable guide 81 of the tape cutting unit 80 are integrally configured, thereby making it possible to share the drive unit, thereby suppressing increases in costs.

(Action and Effects)
As described above, the component supply device 5 of this embodiment comprises a tape feed unit 60 that transports the taped component string 30, which has components with leads 31 held on the tape body 34, along the transport path 53 in the transport direction Y1 and sends the components 31A to the pick-up position 5a, a lead cutting unit 70 that cuts the leads 33 of the components 31A at the pick-up position 5a, and a tape cutting unit 80 that cuts the tape body 34A after the leads 33 have been cut, and the lead cutting unit 70 and tape cutting unit 80 are configured as an integral unit.

With this configuration, the lead cutting unit 70 and the tape cutting unit 80 are integrally configured, so that the lead cutting unit 70 and the tape cutting unit 80 can be driven simultaneously or by a common cutting drive source 71, thereby increasing processing functions while suppressing increases in costs.

The component supply device 5 of the embodiment further includes a common cutting drive source 71 (drive source) that drives the lead cutting unit 70 and the tape cutting unit 80. This configuration can prevent costs from increasing.

In the component supply device 5 of the embodiment, the lead cutting section 70 has a first movable guide 73 having a cutting edge portion 75 (first cutting edge portion) that can engage with the lead 33, and a first fixed guide 74 that is provided at a position facing the first movable guide 73 across the component 31A, and the tape cutting section 80 has a second movable guide 81 having a cutting edge portion 84 (second cutting edge portion) that can engage with the tape body 34, and a second fixed guide 82 that is provided at a position facing the second movable guide 81 across the tape body 34, and the first movable guide 73 and the second movable guide 81 are integrally configured. With this configuration, it is possible to configure the necessary parts as an integral unit while configuring the other parts separately.

In addition, in the component supply device 5 of the embodiment, the first movable guide 73 and the second movable guide 81 are driven to rotate about a common rotation axis Ax extending along the conveying direction Y1. This configuration makes it easier to integrally perform the operations of cutting the lead 33 and the tape body 34, which are different cutting targets.

In addition, in the component supply device 5 of the embodiment, the cutting edge portion 75 (first cutting edge portion) extends along the conveying direction Y1, and the cutting edge portion 84 (second cutting edge portion) extends along a direction intersecting the conveying direction Y1. With this configuration, the directions in which the cutting edge portion 75 and the cutting edge portion 84 each extend can be set to appropriate directions depending on the positions and orientations of the leads 33 and tape body 34 to be cut.

In addition, in the component supply device 5 of the embodiment, the distance (length D3) between the blade tip 75 (first blade tip) and the blade tip 84 (second blade tip) in the transport direction Y1 is shorter than the pitch P between the components 31 in the taped component series 30. With this configuration, the leads 33 and the tape body 34 can be cut in close positions, making it easier to perform the operation of cutting them together.

In addition, in the component supply device 5 of the embodiment, when the first movable guide 73 and the second movable guide 81 are in the retracted position, the gap (length D2) between the second movable guide 81 and the second fixed guide 82 is narrower than the gap (length D1) between the first movable guide 73 and the first fixed guide 74. With this configuration, it becomes easier to push the second movable guide 81 further inward, and the tape body 34, which has a wide cutting range, can be cut more accurately.

In addition, in the component supply device 5 of the embodiment, a cover member 102 is provided above the operating range of the cutting edge portion 75 (first cutting edge portion). With this configuration, the space in which a person's fingers or the like may get into the gap between the first movable guide 73 and the first fixed guide 74 can be reduced, improving safety.

In addition, in the component supply device 5 of the embodiment, the cover member 102 is positioned below the body 32 of the component 31A at the pickup position 5a. With this configuration, the cover member 102 can prevent the component 31A from falling over.

In addition, in the component supply device 5 of the embodiment, the cover member 102 is fixedly installed. With this configuration, it is possible to suppress an increase in costs.

The component supply device 5 of the embodiment further includes a used tape guide section 90 that guides the tape body 34 cut by the tape cutting section 80, and the width (length D5) of the tape guide passage 96 of the used tape guide section 90 is wider than the width (length D6) of the transport path 53. This configuration can prevent the used tape from clogging.

In addition, in the component supply device 5 of the embodiment, the width (length D5) of the tape guide passage 96 is longer than the total height (length D4) including the cut tape body 34A and the leads 33A remaining on the tape body 34A. This configuration makes it easier to tip the used tape sideways in the used tape guide section 90, and prevents the tape from jamming.

In addition, in the component supply device 5 of the embodiment, when viewed along the transport direction Y1, the center C1 of the width of the used tape guide section 90 is offset from the center C2 of the width of the transport path 53. This configuration makes it easier to control the direction in which the used tape body 34A falls in one direction, thereby preventing tape jams.

As described above, the component supply method of this embodiment includes a step (S2) of using the tape feed unit 60 to transport the taped component train 30, which holds the components 31 with leads on the tape body 34, in the transport direction Y1 along the transport path 53 to transport the components 31A to the pick-up position 5a, a step (S3) of using the lead cutting unit 70 to cut the leads 33 of the components 31A at the pick-up position 5a, and a step (S4) of using the tape cutting unit 80, which is configured integrally with the lead cutting unit 70, to cut the tape body 34A after the leads 33 have been cut.

This method allows you to increase processing capabilities while keeping costs down.

Although the present disclosure has been described above with reference to the above-mentioned embodiments, the present disclosure is not limited to the above-mentioned embodiments. For example, in the present embodiment, the case where the leaded component 31 is a radial component has been described, but the present disclosure is not limited to such a case, and may be, for example, an axial component or other types of leaded components.

In the embodiment, the cover member 102 is fixed, but the present invention is not limited to this, and may be movable. An example of a movable cover member will be described with reference to Figures 13A to 13C.

Figures 13A to 13C are front views that show a schematic view of the surrounding configuration of the cover member 200 according to the modified example.

As shown in Figures 13A to 13C, a movable cover member 200 is attached to the first movable guide 73. The cover member 200 includes a movable cover 201 and a biasing portion 202. The movable cover 201 is attached to the first movable guide 73 in a state in which it can slide relatively along the sliding direction A. The movable cover 201 has a tip portion 204 that can engage with the lead 33 of the component 31A. The biasing portion 202 is a member (e.g., a spring) that biases the cover member 200 toward the lead 33 of the component 31A, and applies a biasing force F to the cover member 200.

When the first movable guide 73 is driven from the retracted position shown in FIG. 13A and rotates in a direction approaching the lead 33 of the component 31A, the tip 204 of the movable cover 201 abuts against the lead 33 of the component 31, as shown in FIG. 13B. While the tip 204 of the movable cover 201 remains in contact with the lead 33 of the component 31, the movable cover 201 slides relatively in the direction opposite to the biasing force F.

When the blade tip 75, which is the tip of the first movable guide 73, comes into contact with the lead 33 of the component 31 and is pressed in, the lead 33 of the component 31A is cut as shown in FIG. 13C, resulting in a used tape body 34A (not shown) and lead 33A.

According to the above configuration, by using the movable (shutter-type) cover member 200, the lead 33 can be cut by the first movable guide 73 while the tip 204 of the movable cover 201 is in contact with the lead 33 of the component 31A. This allows the lead 33 to be cut while being positioned and held, and the cutting operation of the lead 33 can be performed with greater precision.

According to the modified component supply device, the cover member 200 has a movable cover 201 that moves integrally with the first movable guide 73 of the lead cutting section 70, and a biasing section 202 that biases the movable cover 201 toward the lead 33 of the component 31A, and the movable cover 201 moves between a retracted position (FIG. 13A) away from the lead 33 of the component 31A and an operating position (FIGS. 13B and 13C) in which it comes into contact with the lead 33 of the component 31A.

According to the above configuration, by making the cover member 200 movable (shutter type), the cutting operation of the lead 33 can be performed with greater precision while improving safety.

Although the present disclosure has been fully described in connection with the preferred embodiments with reference to the accompanying drawings, various variations and modifications will be apparent to those skilled in the art. Such variations and modifications are to be understood as being included within the scope of the present disclosure as defined by the appended claims, unless they deviate therefrom. In addition, changes in the combination and order of elements in each embodiment may be made without departing from the scope and spirit of the present disclosure.
