[0022] (Embodiment) Hereinafter, an embodiment will be described with reference to the drawings.

[0023] [Overall configuration] Fig. 1 is a schematic diagram showing a component mounting apparatus 1 according to an embodiment of the present disclosure. Fig. 2 is a block diagram showing a system configuration of the component mounting apparatus 1 of Fig. 1.

[0024] <Component mounting equipment> 1, component mounting apparatus 1 is an apparatus that mounts components P (electronic components), such as chip components or components with leads, onto a substrate 3 on which the components are to be mounted. Component mounting apparatus 1 includes a component supply device 50, a mounting head 10, a mounting head moving device 12, a substrate transport unit 2, a component camera 14, and a control unit 36 ​​(FIG. 2).

[0025] The board transport unit 2 is a device that transports the board 3 to a mounting work position located in the center of the base 1a and transports the board 3 from the mounting work position. More specifically, the board transport unit 2 transports the board 3 in the X direction, which is transported from the upstream side of a component mounting system (not shown) including the component mounting device 1, and positions and holds the board 3 at the mounting work position. When the component mounting work is completed, the board transport unit 2 transports the board 3 downstream of the component mounting system.

[0026] The component supply devices 50 are arranged at both ends of the base 1a in the Y direction. The component supply device 50 includes a stick feeder 4, a tape feeder 5, and a tray feeder 7 as multiple component supply devices. On one side of the base 1a in FIG. 1, multiple stick feeders 4 are arranged along the X direction. On the other side of the base 1a in FIG. 1, multiple tape feeders 5 are arranged along the X direction. A tray feeder 7 having a component tray 6 is arranged next to the multiple tape feeders 5.

[0027] The component supply device 50, which includes the stick feeder 4, tape feeder 5, and tray feeder 7, supplies components P to be mounted on the board 3. In FIG. 2, only the stick feeder 4 is shown as a representative of the component supply device 50.

[0028] The mounting head moving device 12 comprises a Y-axis beam 8 and an X-axis beam 9. The Y-axis beam 8 has linear drive devices at both ends in the X direction on the upper surface of the base 1a. The X-axis beam 9 has similar linear drive devices and is connected to the Y-axis beam 8. A mounting head 10 is attached to the X-axis beam 9 so that it can move in the X direction. The linear drive device provided in the Y-axis beam 8 moves the X-axis beam 9 in the Y direction, and the linear drive device provided in the X-axis beam 9 moves the mounting head 10 in the X direction.

[0029] Mounting head moving device 12 controls the linear drive device described above to move mounting head 10 to pickup position 21b of stick feeder 4, pickup position of tape feeder 5, or pickup position of component tray 6. Components P picked up by mounting head 10 at pickup position 21b are transferred to and mounted at a mounting position on board 3 held by board transport section 2. Component mounting apparatus 1 repeatedly executes the series of processes from transporting board 3 to mounting components P described above.

[0030] 1, a component camera 14 is provided between the board transport unit 2 and the component supply device 50. The mounting head 10, which has picked up a component P from the component supply device 50, moves above the component camera 14, thereby acquiring an image of the component P held by the mounting head 10. The acquired image is subjected to recognition processing, thereby detecting any misalignment of the component P while it is held by the mounting head 10.

[0031] A board camera 31 that moves integrally with the mounting head 10 is attached to the mounting head 10. The board camera 31 is an imaging unit with an imaging function, and is attached to the mounting head 10 with its imaging optical axis facing downward. The board camera 31, for example, captures an image of the board 3 facing downward, and by recognizing and processing the captured image, the positional deviation of the board 3, i.e., the positional deviation of the mounting point, is detected. Then, based on the detection results of the positional deviation of the component P and the positional deviation of the mounting point, positional correction is performed during component mounting. The positional correction includes rotational alignment, which aligns the rotational position of the component P around the θ axis in the correct direction.

[0032] The control unit 36 ​​is a component that controls each component of the component mounting apparatus 1. The control unit 36 ​​can be configured with, for example, a CPU, MPU, DSP, FPGA, ASIC, etc. The functions of the control unit 36 ​​may be configured with hardware alone, or may be realized by combining hardware and software. The control unit 36 ​​realizes predetermined functions by reading data and programs stored in a memory area (not shown) within the control unit 36 ​​and performing various arithmetic processing. The control unit 36 ​​is also electrically connected to the feeder control unit 32 of the stick feeder 4 shown in FIG. 2.

[0033] Fig. 3 is a front view that schematically shows the mounting head 10 of the component mounting apparatus 1. As shown in Fig. 3, the mounting head 10 includes a chuck 11 for chucking and holding the component P. The chuck 11 chucks the component P by clamping the component body of the component P between a pair of claws.

[0034] The mounting head 10 includes, as devices for driving the chuck 11, a chuck lifting device 10a, a chuck rotating device 10b, and a chuck opening and closing device 10c.

[0035] The chuck lifting device 10a lifts and lowers the chuck 11 (arrow a). The chuck rotating device 10b rotates the chuck 11 around a rotation axis AN in the Z direction (arrow b). The chuck opening and closing device 10c opens and closes a pair of jaws that make up the chuck 11 in the horizontal direction (arrow c). In FIG. 3, the chuck lifting device 10a, chuck rotating device 10b, and chuck opening and closing device 10c are all shown schematically, and may be located in any desired position.

[0036] Here, the operation of the component mounting apparatus 1 will be described. The component mounting apparatus 1 mounts components P supplied from a component supply device 50 (e.g., stick feeder 4) onto a board 3 carried in from upstream of a component mounting system (not shown). A board transport unit 2 transports the board 3 from upstream of the component mounting system to a component mounting position. Next, the mounting head moving device 12 moves the mounting head 10 to pick up the components P supplied from the component supply device 50, and the component camera 14 identifies the polarity of the components P and the positions of their lead wires.

[0037] Based on the identified polarity of component P and the position of the lead wire, mounting head moving device 12 further moves mounting head 10 to mount component P on board 3. Once mounting of component P on board 3 is complete, board transport unit 2 removes board 3 and then loads into component mounting device 1 the next board 3 onto which component P is to be mounted.

[0038] <Stick feeder> Fig. 4 is a schematic perspective view showing the configuration of stick feeder 4 arranged in component mounting apparatus 1. Fig. 5 is a side view of stick feeder 4 of Fig. 4. Fig. 6 is a schematic diagram for explaining each component of stick feeder 4 of Fig. 4.

[0039] As shown in Figures 4 and 5, the stick feeder 4 includes a loading unit 23, a feeder 21, a component sensor 22 (see Figure 6), a pusher 24, a pusher drive unit 25 (see Figure 2), and a feeder control unit 32 (see Figure 2).

[0040] Each component of the stick feeder 4 will be described with reference to FIG. 6. The loading section 23 stacks a plurality of sticks ST. The plurality of sticks ST have a first end E1 and a second end E2, and form a component storage space 60 that stores a plurality of components P between the first end E1 and the second end E2. The first end E1 and the second end E2 are each open, and the component storage space 60 communicates with the outside. In this embodiment, the plurality of sticks ST are formed in a cylindrical shape, and store a plurality of components P lined up in a line in the internal component storage space 60. Here, stacking a plurality of sticks ST means stacking the sticks ST in the +Z direction.

[0041] Feeder 21 is a member that is connected to a first end E1 of one stick ST1 (hereinafter referred to as stick ST1) among the multiple sticks ST, and forms a component passage 70 along which multiple components P supplied from stick ST1 travel. Feeder 21 has an inlet 21a for introducing components P into component passage 70, and inlet 21a is connected to first end E1 of stick ST1.

[0042] Feeder 21 has a pickup position 21b at the end opposite to entrance 21a. Component passage 70 of feeder 21 is a path along which components P pass from first end E1 of stick ST1 to pickup position 21b. In this embodiment, as shown in FIG. 6, feeder 21 has support 72 that supports multiple components P in the +Z direction, and a gap is formed between stick ST1 and support 72 large enough to prevent components P from falling.

[0043] In the feeder 21, a plurality of components P that have passed through the entrance 21a are placed in the component passage 70, and one of these components P that is positioned at the pickup position 21b is picked up by the mounting head 10.

[0044] Component sensor 22 is disposed at pickup position 21b of feeder 21. Component sensor 22 is a sensor that detects the presence or absence of component P or pusher 24 at pickup position 21b. Component sensor 22 outputs an ON signal when component P or pusher 24 is located at pickup position 21b, and outputs an OFF signal when neither component P nor pusher 24 is located at pickup position 21b. The ON / OFF signal from component sensor 22 is transmitted to feeder control unit 32. Component sensor 22 can be any sensor that can detect the presence or absence of component P or pusher 24, such as a photosensor.

[0045] The pusher 24 moves in the -Y direction (first direction M1) from a starting point S1 located outside the second end E2 of the stick ST1, and enters the component storage space 60 of the stick ST1 via the second end E2. The pusher 24 pushes the components P stored in the component storage space 60 downstream and transfers them from the stick ST1 to the feeder 21 together with the components P. The pusher 24 pushes the components P toward the pickup position 21b in the component passage 70 of the feeder 21. As a result, the components P are sequentially supplied to the pickup position 21b and picked up by the mounting head 10. When all of the components P on the stick ST1 have been picked up at the pickup position 21b, the pusher 24 moves in the +Y direction (second direction M2) and returns to the starting point S1.

[0046] The pusher 24 can be moved forward and backward in the Y direction by a pusher driving unit 25 (see FIG. 2). The pusher 24 is connected to a wire 26, and the pusher driving unit 25 drives the wire 26, causing the pusher 24 to move forward and backward in the Y direction.

[0047] In this embodiment, an origin sensor 29 is disposed at the start point S1 of the pusher 24. The origin sensor 29 detects the presence or absence of an origin mark 24a provided on the pusher 24 at the start point S1. When the pusher 24 is located at the start point S1, the origin sensor 29 detects the presence of the origin mark 24a at the start point S1.

[0048] The pusher driving unit 25 moves the pusher 24 forward and backward in the Y direction. In this embodiment, the pusher driving unit 25 includes a servo motor (not shown) and a pair of rollers 27. The wire 26 moves forward and backward in the Y direction depending on the direction and amount of rotation of the rollers 27. As the wire 26 moves, the pusher 24 moves in the +Y direction or the -Y direction.

[0049] The portion of the wire 26 that extends outward beyond the roller 27 is housed in a tubular wire housing portion 28 and protected.

[0050] Feeder control unit 32 controls pusher drive unit 25. In this embodiment, feeder control unit 32 controls each component of stick feeder 4 based on the detection results of component sensor 22 and origin sensor 29. Specifically, feeder control unit 32 drives pusher drive unit 25 to move pusher 24 forward and backward. Feeder control unit 32 controls the movement distance of pusher 24 based on the drive amount of the servo motor and the radius of roller 27.

[0051] A stick exchange lever 30 is disposed in the stacking section 23. One end 30a of the stick exchange lever 30 supports the stick ST1, and the other end 30b supports the stick ST stacked on the stick ST1. A rotation center 30c is provided between the one end 30a and the other end 30b of the stick exchange lever 30. The stick exchange lever 30 rotates between a position in which the one end 30a supports the stick ST1 and a position in which the support for the stick ST1 is released and the other end 30b supports the sticks ST2 and ST3 above it. The rotation of the stick exchange lever 30 is controlled, for example, by the feeder control section 32. When all the components P contained in the stick ST1 are pushed into the feeder 21 and the stick ST1 becomes empty, the pusher drive section 25 moves the pusher 24 back to the starting point S1. At this time, the stick ST1 can be replaced with the next stick ST2.

[0052] Next, the internal structure of feeder 21 of this embodiment and the structures of pusher 24 and parts P arranged in feeder 21 will be described with reference to FIG. 7 and subsequent drawings.

[0053] 7 and 8 are a plan view and a side view, respectively, that schematically show the pusher 24 and parts P1 and P2 arranged in the part passage 70 of the feeder 21. While Figs. 7 and 8 illustrate a state in which the pusher 24 is pushing two parts P1 and P2, the number of parts P1 and P2 may be any number.

[0054] 7 and 8, the pusher 24 is attached to a wire 26 extending in an axial direction A and is movable in a first direction M1 and a second direction M2. In this embodiment, the pusher 24 is attached to the wire 26 so as to be rotatable about the axial direction A. Because the pusher 24 is rotatable, the orientation of the pusher 24 can be automatically adjusted according to the shape of the bottom surface of the component storage space 60 and the component passage 70 as the pusher 24 moves.

[0055] 7 and 8, part P1 is located at the front along the first direction M1, and part P2 is located immediately in front of part P1. Parts P1 and P2 each have a front surface and a rear surface, and the rear surface of part P1 comes into contact with the front surface of part P2, and the rear surface of part P2 is pushed by pusher 24. Parts P1 and P2 move together in the first direction M1.

[0056] Each of the components P1 and P2 is a leaded component (for example, a connector component) having leads (not shown). A component rail 120 shaped to avoid the leads is used as a member for running the components P1 and P2.

[0057] The component rails 120 are a pair of rails spaced apart in the X direction, which is the width direction of the component passage 70, and extend parallel to each other in the first direction M1.

[0058] The feeder 21 has, as wall portions that define the component passage 70, a pair of side walls 116A, 116B shown in FIG. 7, an upper wall 118 shown in FIG. 8, and the pair of component rails 120 described above.

[0059] FIG. 9 is a side view that schematically shows the peripheral configuration of the pickup position 21b.

[0060] 9, in this embodiment, component rail 120 extends horizontally and is tilted downward relative to the horizontal at pickup position 21b. As a result, component P1 at pickup position 21b is tilted forward from its upright position, forming a gap S1 between it and the immediately preceding component P2, which is in an upright position. The chuck 11 of mounting head 10 can insert one claw into gap S1, allowing it to clamp and chuck component P1 in first direction M1, which is the direction of travel of components P1 and P2.

[0061] This configuration can also accommodate cases where the specifications of the components P1 and P2 make it impossible to sandwich the component P1 in the width direction (X direction) of the component passage 70. This can broaden the range of application of the stick feeder 4 and the component mounting device 1 to the specifications of the components P1 and P2.

[0062] As shown in FIG. 9, the component rail 120 has a first support portion 121 and a second support portion 122.

[0063] The first support portion 121 is a portion that supports the component P1 at the pickup position 21b, and is provided at the most downstream side of the component rail 120. The second support portion 122 is a portion that supports the component P2 immediately before the component P1 at the pickup position 21b, and is provided adjacent to the first support portion 121.

[0064] A stopper 124 is attached to the tip of the first support portion 121. The stopper 124 is a member for stopping the component P1 at the pickup position 21b.

[0065] The portion of the component rail 120 upstream of the first support portion 121, including the second support portion 122, extends horizontally. In contrast, the first support portion 121 extends at an angle downward relative to the horizontal direction toward the first direction M1, which is the direction of travel.

[0066] A first plane 121A including the upper surface of the first support portion 121 is inclined downward in the first direction M1 by an inclination angle θ1 with respect to a second plane 122A including the upper surface of the second support portion 122. The inclination angle θ1 may be set to, for example, 5 degrees or more and 10 degrees or less.

[0067] The stopper 124 is inclined obliquely forward with respect to the vertical direction so as to be oriented in the same direction as the part P1 in an oblique position.

[0068] By changing the inclination of the first support portion 121 and the second support portion 122 in this manner, a gap S1 is formed between the upper ends of the components P1 and P2, and the chuck 11 of the mounting head 10 can chuck the component P1 by clamping it in the first direction M1.

[0069] 10A and 10B are schematic side views for explaining the operation of chucking the component P1 at the pickup position 21b with the mounting head 10. FIG.

[0070] 10A, the mounting head 10 positioned above the pickup position 21b descends (arrow Z1), causing one chuck 11 to enter the gap S1, and the two chucks 11 clamp the component P1 in the first direction M1. After the chucks 11 are moved in the closing direction to chuck the component P1, the mounting head 10 is raised (arrow Z2) as shown in FIG. 10B to pick up the component P1.

[0071] Although the part P1 is tilted relative to the upright position, the tilt angle θ1 is set to a relatively small angle (for example, 10 degrees or less), so that the part P1 can be precisely clamped between the pair of chucks 11. When the chucks 11 are closed, the position of the part P1 is corrected to the upright position according to the orientation of the chucks 11.

[0072] As described above, by inclining the first support portion 121 downward in the first direction M1 relative to the second support portion 122, a gap S1 is formed between the upper ends of the components P1 and P2, ensuring space for inserting the chuck 11. This allows the component P1 at the pickup position 21b to be clamped and chucked in the first direction M1, and can also accommodate specifications for the components P1 and P2 that cannot be clamped in the width direction (X direction) of the component passage 70.

[0073] (Actions and Effects) As described above, the component mounting apparatus 1 of the embodiment is a component mounting apparatus that chucks components P1 supplied from a stick feeder 4 with a mounting head 10 and mounts them on a board 3. The stick feeder 4 includes a stick ST that forms a component storage space 60 that stores a plurality of components P1, P2 in a line, a component rail 120 that is connected to a first end of the stick ST and that causes the plurality of components P1, P2 to travel to a pickup position 21b by the mounting head 10, and a pusher 24 that pushes the plurality of components P1, P2 in a first direction M1 (traveling direction) toward the pickup position 21b. The component rail 120 has a first support portion 121 that supports the component P1 (first component) at the pickup position 21b, and a second support portion 122 that supports the component P2 (second component) immediately before the component P1, the first support portion 121 being arranged to face downward relative to the second support portion 122 in the first direction M1, and the mounting head 10 clamps and chucks the component P1 at the pickup position 21b in the first direction M1.

[0074] With this configuration, a gap S1 is provided between the upper ends of the components P1 and P2, and the component P1 can be picked up by sandwiching it in the first direction M1 (travel direction), which also accommodates cases where the components P1 and P2 cannot be chucked in the width direction of the component rail 120. This allows for a wider range of application of the stick feeder 4 and the component mounting device 1 to the specifications of the components P1 and P2.

[0075] Furthermore, in the component mounting apparatus 1 of the embodiment, the first support portion 121 is inclined downward relative to the horizontal direction in the first direction M1 (travel direction), and the second support portion 122 extends horizontally. With this configuration, the portion of the component rail 120 upstream of the first support portion 121, including the second support portion 122, can be made horizontal as a whole, which simplifies the configuration and makes it less likely for components P1 and P2 to become clogged.

[0076] Furthermore, in the component mounting apparatus 1 of the embodiment, the angle formed between the first support portion 121 and the second support portion 122 is equal to or greater than 5 degrees and equal to or less than 10 degrees. With this configuration, the mounting head 10 can chuck the component P1 with high precision while maintaining an appropriate gap S1 between the upper ends of the components P1 and P2.

[0077] As described above, the stick feeder 4 of this embodiment includes a stick ST that defines a component storage space 60 that stores a plurality of components P1, P2 in a row, a component rail 120 that is connected to a first end of the stick ST and that runs the plurality of components P1, P2 to a pickup position 21b for the mounting head 10, and a pusher 24 that pushes the plurality of components P1, P2 in a first direction M1 (traveling direction) toward the pickup position 21b. The component rail 120 has a first support portion 121 that supports the component P1 (first component) at the pickup position 21b and a second support portion 122 that supports the component P2 (second component) immediately preceding the component P1, and the first support portion 121 is disposed so as to face downward in the first direction M1 relative to the second support portion 122.

[0078] With this configuration, the range of application of the stick feeder 4 can be expanded in accordance with the specifications of the parts P1 and P2.

[0079] (Variation) In the above embodiment, an example was given in which the first support portion 121 is inclined downward and the second support portion 122 extends horizontally, but this is not limited to such a case, and the first support portion 121 may be arranged so as to face downward relatively to the second support portion 122 in the first direction M1.

[0080] FIG. 11 is a schematic side view showing the configuration around pickup position 21b in feeder 200 according to the first modification.

[0081] As shown in FIG. 11, the feeder 200 according to the first modification includes an upper wall 218, a component rail 220, and a stopper 224, and forms a component passage 270.

[0082] The upper wall 218 and the component rail 220 are inclined upward relative to the horizontal direction toward the first direction M1, which is the direction of travel. At the pickup position 21b, the inclination angle of the component rail 220 changes and the component rail 220 extends horizontally.

[0083] A first plane 221A including the upper surface of the first support portion 221 is inclined downward by an inclination angle θ2 in the first direction M1 with respect to a second plane 222A including the upper surface of the second support portion 222.

[0084] In the configuration shown in FIG. 11, the first support portion 221 faces downward relative to the second support portion 222 in the first direction M1, so that a gap S2 is formed between the upper ends of the components P1 and P2, and the component P1 can be clamped in the first direction M1 by the mounting head 10 (not shown) and chucked.

[0085] Because the first support portion 221 extends horizontally, the component P1 at the pickup position 21b is in an upright position, allowing the chuck 11 of the mounting head 10 to pick up the component P1 with greater accuracy. The stopper 224 extends vertically so as to follow the upright position of the component P1.

[0086] In the feeder 200 according to the first modification, the first support portion 221 extends horizontally, and the second support portion 222 is inclined upward relative to the horizontal direction toward the first direction M1 (traveling direction). With this configuration, it is possible to sandwich and chuck the component P1 in the first direction M1, which is the traveling direction of the component P1, and by making the first support portion 221 horizontal, it becomes easier for the mounting head 10 to chuck the component P1 with high precision.

[0087] FIG. 12 is a schematic side view showing the configuration around pickup position 21b in feeder 300 according to the second modification.

[0088] As shown in FIG. 12, the feeder 300 according to the second modification includes an upper wall 318, a component rail 320, and a stopper 324, and forms a component passage 370.

[0089] The upper wall 318 and the component rail 320 are inclined downward relative to the horizontal direction in the first direction M1, which is the direction of travel. At the pickup position 21b, the inclination angle of the component rail 320 changes and the component rail 320 is further inclined downward.

[0090] A first plane 321A including the upper surface of the first support portion 321 is inclined downward by an inclination angle θ3 in the first direction M1 with respect to a second plane 322A including the upper surface of the second support portion 322.

[0091] In the configuration shown in Figure 12, the first support portion 321 faces downward relatively in the first direction M1 with respect to the second support portion 322, so that a gap S3 is formed between the upper ends of the components P1 and P2, and the component P1 can be clamped in the first direction M1 by the mounting head 10 (not shown) and chucked.

[0092] Since the first support portion 321 is tilted downward, the component P1 at the pickup position 21b is in an oblique position. The stopper 324 is inclined relative to the vertical direction so as to follow the oblique position of the component P1.

[0093] Since the entire component rail 320 is inclined downward, the pusher 24 can easily push the components P1 and P2 in, and the components P1 and P2 move smoothly.

[0094] In the feeder 300 according to the second modification, the second support portion 322 is inclined downward relative to the horizontal direction in the first direction M1 (travel direction), and the first support portion 321 is inclined further downward relative to the second support portion 322 in the first direction M1.

[0095] With this configuration, the pusher 24 can push the parts P1 and P2 more smoothly.

[0096] FIG. 13 is a schematic side view showing the configuration around pickup position 21b in feeder 400 according to the third modification.

[0097] As shown in FIG. 13, the feeder 400 according to the third modification includes an upper wall 418, a component rail 420, and a stopper 424, and forms a component passage 470.

[0098] The component rail 420 has a first support portion 421 , a second support portion 422 , and a third support portion 423 .

[0099] The first support portion 421 is located at the pickup position 21b, the second support portion 422 is located adjacent to the upstream side of the first support portion 421, and the third support portion 423 is located adjacent to the upstream side of the second support portion 422.

[0100] The inclination angle of the component rail 420 changes in the section between the support portions 421, 422, and 423 so that the rail faces more downward in the first direction M1.

[0101] The third support portion 423 extends horizontally in the first direction M1. The second support portion 422 is inclined downward in the first direction M1 relative to the third support portion 423. The first support portion 421 is inclined downward in the first direction M1 relative to the second support portion 422.

[0102] A first plane 421A including the upper surface of the first support portion 421 is inclined downward by an inclination angle θ4 in the first direction M1 relative to a second plane 422A including the upper surface of the second support portion 422. The second plane 422A including the upper surface of the second support portion 422 is inclined downward by an inclination angle θ5 in the first direction M1 relative to a third plane 423A including the upper surface of the third support portion 423.

[0103] FIG. 14 is a schematic side view showing a state in which three parts P1, P2, and P3 are pushed into the part rail 420 of the feeder 400 by the pusher 24. As shown in FIG.

[0104] As shown in FIG. 14, the component P1 is supported by the first support portion 421, the component P2 is supported by the second support portion 422, and the component P3 is supported by the third support portion 423.

[0105] Since the first support portion 421 is inclined downward relative to the second support portion 422 in the first direction M1, a gap S4 is formed between the upper ends of the components P1 and P2, and the component P1 can be clamped in the first direction M1 by the mounting head 10 (not shown) and chucked.

[0106] After component P1 is picked up, components P2 and P3 move forward in the first direction M1, whereupon component P2 is supported by the first support portion 421 and component P3 is supported by the second support portion 422. A gap S4 is also formed between the upper ends of components P2 and P3, allowing them to be chucked in a similar manner.

[0107] FIG. 15 is a schematic side view showing a state in which two components P4 and P5 are pushed into component rail 420 of feeder 400 by pusher 24. As shown in FIG.

[0108] The parts P4 and P5 shown in FIG. 15 are parts with specifications different from the parts P1 to P3 shown in FIG. 14, and are longer than the parts P1 to P3 in particular in length along the first direction M1 which is the direction of travel.

[0109] 15, the leading component P4 has a length that spans both the first support portion 421 and the second support portion 422, and in the example shown in Fig. 15, is mainly supported by the second support portion 422. The component P5 immediately preceding the component P4 is mainly supported by the third support portion 423.

[0110] Since the second support portion 422 is inclined downward relative to the third support portion 423 in the first direction M1, a gap S5 is formed between the upper ends of the components P4 and P5, and the component P4 can be clamped in the first direction M1 by the mounting head 10 (not shown) and chucked.

[0111] As described above, by providing three support portions 421, 422, and 423 with different inclinations, it becomes possible to accommodate components with different specifications (particularly lengths along the first direction M1), such as components P1 to P3 shown in Fig. 14 and components P4 and P5 shown in Fig. 15. This further widens the range of application.

[0112] In 421 according to the third modification, the component rail 420 has, in addition to the first support portion 421 and the second support portion 422, a third support portion 423 that supports the component P3 (third component) immediately before the component P2 (second component), and the second support portion 422 is arranged to face downward relative to the third support portion 423 in the first direction M1 (travel direction).

[0113] With this configuration, even if the specifications of components P1 to P3 change and components P4 and P5 that are large enough to span both components P1 and P2 are used, a gap S5 is formed between the upper ends of component P4 at pickup position 21b and the component P5 immediately before it, and the mounting head 10 can chuck component P1 by clamping it in the first direction M1.

[0114] FIG. 16 is a schematic side view showing the configuration around pickup position 21b in feeder 500 according to the fourth modification.

[0115] As shown in FIG. 16, a feeder 500 according to the fourth modification includes an upper wall 518, a component rail 520, and a stopper 524, and forms a component passage 570.

[0116] The component rail 520 has a curved portion 525 at a location that includes the pickup position 21b.

[0117] The curved portion 525 is a portion that smoothly curves downward as it approaches the first direction M1. The curved portion 525 functions as a support portion that supports the component at the pickup position 21b and the component in front of it. The curved portion 525 has a first support portion 521, a second support portion 522, and a third support portion 523.

[0118] FIG. 17 is a schematic side view showing a state in which three parts P1, P2, and P3 are pushed into part rail 520 of feeder 500 by pusher 24. As shown in FIG.

[0119] As shown in FIG. 17, the leading part P1 is supported by the first support part 521 of the curved part 525, the part P2 immediately before part P1 is supported by the second support part 522 of the curved part 525, and the part P3 immediately before part P2 is supported by the third support part 523 of the curved part 525.

[0120] Since the first support portion 521 is inclined downward relative to the second support portion 522 in the first direction M1, a gap S6 is formed between the upper ends of the components P1 and P2, and the component P1 can be clamped in the first direction M1 by the mounting head 10 (not shown) and chucked.

[0121] The same is true after part P1 is picked up.

[0122] FIG. 18 is a schematic side view showing a state in which two components P4 and P5 are pushed into component rail 520 of feeder 500 by pusher 24. As shown in FIG.

[0123] Components P4 and P5 shown in FIG. 18 have specifications different from components P1 to P3 shown in FIG. 17, and are particularly longer in length along the first direction M1, which is the direction of travel.

[0124] As shown in FIG. 18, the leading component P4 is mainly supported by the first support portion 521 of the curved portion 525, and the component P5 immediately before the component P4 is mainly supported by the third support portion 523 of the curved portion 525.

[0125] Since the second support portion 522 is inclined downward relative to the third support portion 523 in the first direction M1, a gap S7 is formed between the upper ends of the components P4 and P5, and the component P4 can be clamped in the first direction M1 by the mounting head 10 (not shown) and chucked.

[0126] The same is true after part P4 is picked up.

[0127] As described above, by providing curved portion 525 that points more downward as it approaches first direction M1, it becomes possible to accommodate components with different specifications, further expanding the range of application.

[0128] In the feeder 500 according to the fourth modification, the component rail 520 has a curved portion 525 at a location including at least the first support portion 521 (pickup position 21b), which curves smoothly so as to point relatively downward as it approaches the first direction M1 (travel direction).

[0129] This configuration can accommodate various changes in the size and shape of the components P1 and P2.

[0130] In another variation, the component rail 120 may be replaceable at least at the portion including the first support portion 121. With this configuration, the first support portion 121 can be replaced in response to changes in the specifications of the components P1 and P2, and the angle θ1 between the first support portion 121 and the second support portion 122 can be easily adjusted.

[0131] As another modification, at least the inclination angle θ1 of the first support portion 121 of the component rail 120 may be variable. With this configuration, the angle θ1 between the first support portion 121 and the second support portion 122 can be easily adjusted in response to changes in the specifications of the components P1 and P2.
