Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments will be described with reference to the drawings. Note that the present invention is not limited by the following mode for carrying out the invention (hereinafter referred to as the embodiment). In addition, the constituent elements in the following embodiments include those that can be easily assumed by those skilled in the art, substantially the same ones, and those within a so-called equivalent range. Furthermore, the constituent elements disclosed in the following embodiments can be combined as appropriate.

[0011] [Mounting Device] FIG. 1 is a plan view schematically showing a schematic configuration of a mounting apparatus 100 on which a component suction nozzle 1 and a nozzle storage device 2 according to an embodiment are mounted. In FIG. 1, the X-axis is a horizontal one-way direction, and the Y-axis is a horizontal direction orthogonal to the X-axis. The mounting apparatus 100 is an apparatus for mounting electronic components on a substrate P. The mounting apparatus 100 includes a base member 101, a substrate transfer device 102, a component supply device 103, a mounting head 104, a head moving device 105, a component state detection unit 106, a nozzle exchange unit 107, and a component storage unit 108.

[0012] The base member 101 supports each of the substrate transfer device 102, the component supply device 103, the mounting head 104, the head moving device 105, the component state detection unit 106, the nozzle exchange unit 107, and the component storage unit 108.

[0013] The substrate transfer device 102 transfers the substrate P supplied to the mounting apparatus 100 to a mounting area DM where the electronic components are mounted by the mounting head 104. The mounting area DM is defined in the transfer path of the substrate transfer device 102. In the embodiment, the substrate transfer device 102 transfers the substrate P in the X-axis direction. The substrate P before the electronic components are mounted is carried into the substrate transfer device 102 from the -X side end of the base member 101. The substrate transfer device 102 transfers the carried-in substrate P in the +X direction and stops it in the mounting area DM. The mounting head 104 mounts the electronic components on the surface of the substrate P disposed in the mounting area DM. The substrate transfer device 102 transfers the substrate P after the electronic components are mounted in the +X direction. The substrate P after the electronic components are mounted is carried out from the +X side end of the base member 101.

[0014] The component supply device 103 supplies electronic components to the supply area SM. The component supply device 103 includes, for example, a plurality of tape feeders. The tape feeders are arranged in the X-axis direction. The supply area SM for the electronic components is defined by the tape feeders. The tape feeder conveys a carrier tape that holds a plurality of electronic components. By conveying the carrier tape, at least one of the plurality of electronic components is supplied to the supply area SM. In the embodiment, the component supply device 103 is arranged on both the +Y side and the -Y side of the substrate transfer device 102. Note that the component supply device 103 may be arranged on either the +Y side or the -Y side of the substrate transfer device 102.

[0015] The mounting head 104 holds the electronic components supplied from the component supply device 103 with the component suction nozzles 1 described later and mounts them on the substrate P. The mounting head 104 may have a plurality of component suction nozzles 1. The mounting head 104 is movable between the supply area SM where the electronic components are supplied and the mounting area DM where the substrate P is arranged. The supply area SM and the mounting area DM are defined at different positions in the XY plane. The mounting head 104 holds the electronic components supplied to the supply area SM with the component suction nozzles 1, moves to the mounting area DM, and then mounts them on the substrate P arranged in the mounting area DM.

[0016] The head moving device 105 is capable of moving the mounting head 104 in each of the X-axis direction, the Y-axis direction, and the vertical direction. The head moving device 105 includes an X-axis driving unit 105X that moves the mounting head 104 in the X-axis direction, a Y-axis driving unit 105Y that moves the mounting head 104 in the Y-axis direction, and a lifting driving unit (not shown) that moves the mounting head 104 in the vertical direction.

[0017] The component state detection unit 106, the nozzle replacement unit 107, and the component storage unit 108 are arranged on the vertically lower side of the mounting head 104 in the movable area of the mounting head 104. In the embodiment, the component state detection unit 106, the nozzle replacement unit 107, and the component storage unit 108 are arranged between the mounting area DM for mounting electronic components on the substrate P and the supply area SM where electronic components for mounting on the substrate P are supplied.

[0018] The component state detection unit 106 is an image recognition device and includes a camera that photographs the vicinity of the component suction nozzle 1 of the mounting head 104 and an illumination unit that illuminates the photographed area. The component state detection unit 106 recognizes the shape of the electronic component adsorbed by the component suction nozzle 1 of the mounting head 104 and the holding state of the electronic component by the component suction nozzle 1.

[0019] The nozzle replacement unit 107 includes the nozzle storage device 2 described later. In the nozzle replacement unit 107, the component suction nozzle 1 stored in the nozzle storage device 2 is attached to the mounting head 104, and the component suction nozzle 1 attached to the mounting head 104 is stored in the nozzle storage device 2. The mounting head 104 can hold the held electronic component under appropriate conditions (suction or gripping) by changing the component suction nozzle 1 to be attached at the nozzle replacement unit 107 and supplying air pressure to the attached component suction nozzle 1 to drive it.

[0020] The component storage unit 108 is a box that stores electronic components that the mounting head 104 holds with the component suction nozzle 1 described later and does not mount on the substrate P. That is, in the mounting device 100, it becomes a waste box for discarding electronic components that are not mounted on the substrate P. When there is an electronic component that is not to be mounted on the substrate P among the electronic components held by the mounting head 104, the mounting device 100 moves the mounting head 104 to a position facing the component storage unit 108 and releases the held electronic component, thereby putting the electronic component into the component storage unit 108.

[0021] [Component suction nozzle] FIG. 2 is a perspective view showing the component suction nozzle 1 according to the embodiment. FIG. 3 is a bottom view showing the component suction nozzle 1 according to the embodiment. FIG. 4 is a cross-sectional view taken along line A-A shown in FIG. 3. The component suction nozzle 1 is a member that is detachably attached to the lower end of a shaft S that is supported by a mounting head 104 in a mounting apparatus 100 for mounting electronic components on a substrate P and is capable of moving up and down and rotating about an axis, and adsorbs and holds the electronic components. The component suction nozzle 1 of the embodiment is assumed to be used for mounting large-sized electronic components for which it is difficult to adsorb and hold with a standard-size component suction nozzle. The component suction nozzle 1 includes a main body portion 10, a branch portion 20, and a plurality of suction portions 30.

[0022] The main body portion 10 is attached to a mounting head 104 mounted on the mounting apparatus 100 via a shaft S. The main body portion 10 is formed in a substantially cylindrical shape that extends in the vertical direction as a whole. The inner peripheral side of the main body portion 10 is a flow path 11 for air to flow. One end of this flow path 11 communicates with a shaft flow path formed in the shaft S, and the other end communicates with one end of a flow path 21 of the branch portion 20 described later. The main body portion 10 includes a gripped portion 12 that is gripped by the lower end portion of the shaft S, a supported flange portion 14 that is supported by a nozzle storage device 2 (see FIGS. 5 and the like) described later, and a connection hole portion 16 to which the branch portion 20 is connected.

[0023] The gripped portion 12 is located at the upper part of the main body portion 10 and is a portion that is attached to the lower end portion of the shaft S. In the embodiment shown in FIG. 2, the gripped portion 12 is formed by arranging a plurality of substantially cylindrical portions and substantially frustoconical portions having different outer diameters in the axial direction (vertical direction). Further, when the gripped portion 12 is attached to the shaft S, in the embodiment, it is fixed to the inner peripheral side of the shaft S. Note that the shape of the gripped portion 12 and the mode of engagement with the shaft S may be the same as those of other component suction nozzles mounted on the mounting apparatus 100 of the same model. For example, in accordance with the state of the shaft S, the lower end portion of the shaft S may be covered from the outer peripheral side and fixed to the outer peripheral side.

[0024] The supported flange portion 14 is formed in a substantially annular shape that protrudes in a flange shape radially (horizontally) outward at a position below the gripped portion 12 of the substantially cylindrical main body portion 10. The supported flange portion 14 is a portion that is supported from the lower surface 14A side by the support portion 46 when the component suction nozzle 1 is stored in the nozzle storage device 2 described later (see FIGS. 5 and 6). In other words, the component suction nozzle 1 is stored in the nozzle storage device 2 in a state where the supported flange portion 14 is supported from the lower surface 14A side.

[0025] The connection hole portion 16 is a hole or recess formed upward from the lower end surface 10A of the substantially cylindrical main body portion 10. The connection hole portion 16 is a part of the flow path 11 and communicates with the flow path 11 formed inside the gripped portion 12 at the bottom surface, that is, the upper end surface. The connection shaft portion 22 of the branch portion 20 is attached to the connection hole portion 16.

[0026] The branch portion 20 is a member that connects to the main body portion 10 and to which a plurality of suction portions 30 are attached. An air flow path 21 is formed inside the branch portion 20. One end of the flow path 21 communicates with the other end of the flow path 11 of the main body portion 10 and branches into a plurality of flow paths toward the other end and connects to the plurality of suction portions 30. The branch portion 20 is attached below the main body portion 10 so as to be vertically movable relative to the main body portion 10. Further, the branch portion 20 is biased downward with respect to the main body portion 10. The branch portion 20 includes a connection shaft portion 22, a first beam-shaped portion 24, and a pair of second beam-shaped portions 26.

[0027] The connection shaft portion 22 constitutes the upper part of the branch portion 20 and is a substantially cylindrical portion extending in the axial direction (vertical direction). A part of the connection shaft portion 22 is inserted downward into the connection hole portion 16 of the main body portion 10. The outer peripheral surface of the connection shaft portion 22 and the inner peripheral surface of the connection hole portion 16 are sealed so as to be slidable in the axial direction (vertical direction). The inner peripheral side of the connection shaft portion 22 is a part of the flow path 21 for air to flow through. In a state where the connection shaft portion 22 is inserted into the connection hole portion 16, the internal flow path 21 communicates with the flow path 11 on the inner peripheral side of the main body portion 10 through the connection hole portion 16.

[0028] In an embodiment, a coiled compression spring 23 for biasing the branch portion 20 downward with respect to the main body portion 10 is provided on the outer peripheral surface side of the portion of the connection shaft portion 22 that is not inserted into the connection hole portion 16. The upper end of the compression spring 23 contacts the main body portion 10 from below, and the lower end contacts the first beam-shaped portion 24 from above.

[0029] The first beam-shaped portion 24 is located below the main body portion 10 and the connection shaft portion 22, extends in a horizontal one direction, and is a plate-shaped or rod-shaped portion that connects to the lower end of the connection shaft portion 22 on the upper surface of the central portion in the longitudinal direction. Inside the first beam-shaped portion 24, the flow path 21 includes a flow path 21A that communicates with the flow path 21 in the connection shaft portion 22, and flow paths 21B, 21B that branch from the flow path 21A in directions along the longitudinal direction respectively.

[0030] The pair of second beam-shaped portions 26 are orthogonal to the first beam-shaped portion 24, extend in a horizontal direction, and are plate-shaped or rod-shaped portions that connect to both ends of the first beam-shaped portion 24 on the side surfaces of the central portions in the longitudinal direction respectively. That is, the first beam-shaped portion 24 and the pair of second beam-shaped portions 26 are provided in an H shape in plan view.

[0031] A plurality (three in the embodiment) of suction portions 30 are evenly arranged in the longitudinal direction on the lower surface side of each second beam-shaped portion 26. In the embodiment, one suction portion 30 is arranged in each of a plurality of recesses 28 provided on the lower surface side of the second beam-shaped portion 26 so that the respective suction portions 30 are partitioned.

[0032] Inside each second beam-shaped portion 26, the flow path 21 includes flow paths 21C, 21C that branch from the flow path 21B branched in the first beam-shaped portion 24 in directions along the longitudinal direction of the second beam-shaped portion 26 respectively, and flow paths 21D that extend vertically downward from the flow paths 21C, 21C and communicate with the respective suction portions 30. That is, in the embodiment, the flow path 21 branches into two in the first beam-shaped portion 24, and branches into three in each second beam-shaped portion 26, for a total of six branches.

[0033] The suction part 30 is a member that sucks and holds electronic components. The suction part 30 has a substantially cylindrical shape extending in the vertical direction and has an opening 32 at the tip (lower end) that communicates with the other end of the flow path 21 of the branch part 20. The component suction nozzle 1 sucks air from the opening 32 of the suction part 30 to suck and hold an electronic component at the tip. The suction part 30 is provided on the lower surface side of the branch part 20. In the embodiment, the upper end of the suction part 30 is fixed to the concave part 28 of the second beam-shaped part 26 and communicates with the flow path 21D.

[0034] In the embodiment, the suction part 30 includes six suction parts 30 arranged in the horizontal direction. More specifically, two of the six suction parts 30 are respectively arranged at positions where the first beam-shaped part 24 and the pair of second beam-shaped parts 26 intersect. Also, four of the six suction parts 30 are respectively arranged at the longitudinal ends of the second beam-shaped part 26.

[0035] As described above, the component suction nozzle 1 is attached to the mounting head 104 of the mounting apparatus 100 via the shaft S by attaching the main body part 10 to the shaft S. A vacuum pressure is supplied through a flow path formed in the shaft S by a vacuum pressure supply mechanism (not shown) on the mounting head 104 side. Thus, in the component suction nozzle 1, an air flow is formed from the opening 32 of the suction part 30 toward the flow paths 21D, 21C, 21B, 21A of the branch part 20, the flow path 11 of the main body part 10, and the shaft S. Thereby, the suction part 30 can suck air from the opening 32 and suck and hold an electronic component at the tip. Since the component suction nozzle 1 in the embodiment sucks and holds an electronic component with a plurality of suction parts 30, it can suck and hold a large-sized electronic component.

[0036] [Nozzle storage device] FIG. 5 is a plan view showing a nozzle storage device 2 according to an embodiment. FIGS. 6 and 7 are plan views showing the nozzle storage device 2 with the component suction nozzles 1 and 3 stored therein. The nozzle storage device 2 is a device for automatically controlling the attachment and detachment of the component suction nozzle 1 shown in FIGS. 2 to 4 to and from the mounting head 104, and stores the component suction nozzle 1. The nozzle storage device 2 is disposed within the movable region of the mounting head 104 to which the component suction nozzle 1 is attached, and in the embodiment, is disposed at the nozzle exchange unit 107 shown in FIG. 1.

[0037] The nozzle storage device 2 is configured to support the supported flange portion 14 of the component suction nozzle 1 from the lower surface 14A side. In the embodiment, the nozzle storage device 2 includes a base portion 40 in which the component suction nozzle 1 is stored from above, and a lid portion 50 that covers at least a part of the component suction nozzle 1 stored in the base portion 40 from above.

[0038] The base portion 40 is provided so as to be fixable, for example, to the base member 101 of the mounting device 100 on which the mounting head 104 to which the component suction nozzle 1 is attached is mounted. The base portion 40 has a first storage hole 42 formed downward from the upper surface and a second storage hole 44.

[0039] The component suction nozzle 1 is stored in the first storage hole 42 from above. As shown in FIG. 6, in the first storage hole 42 of the embodiment, three component suction nozzles 1 are stored side by side in one direction. At this time, the direction in which the component suction nozzles 1 are arranged is parallel to the longitudinal direction of the first beam-like portion 24 of the component suction nozzle 1.

[0040] In plan view, the first storage hole 42 includes a wide portion 42A in which the second beam-shaped portion 26 is stored and a narrow portion 42B in which the first beam-shaped portion 24 is stored, such that the H-shaped outer contour formed by the first beam-shaped portion 24 and the second beam-shaped portion 26 of the component suction nozzle 1 is followed. The first storage hole 42 of the embodiment is formed in a shape in which three H-shapes are connected in series to store three component suction nozzles 1. The hole width of the narrow portion 42B is smaller than the diameter of the supported flange portion 14 of the main body portion 10 and larger than the maximum width of the portion below the supported flange portion 14 including the first beam-shaped portion 24. Support portions 46, which are the upper surfaces of both side edges of the narrow portion 42B, support the supported flange portion 14 from the lower surface 14A side.

[0041] The component suction nozzle 3 is stored in the second storage hole 44 from above. The component suction nozzle 3 is different from the component suction nozzle 1 in which the suction portion 30 is arranged in an H-shape in the embodiment shown in FIGS. 2 to 4 in that it does not have the second beam-shaped portion 26 and the suction portions 30 are arranged at both ends of the first beam-shaped portion 24. As shown in FIG. 6, in the second storage hole 44 of the embodiment, three component suction nozzles 3 are stored side by side in one direction. At this time, the direction in which the component suction nozzles 3 are arranged is parallel to the longitudinal direction of the component suction nozzles 3.

[0042] In plan view, the second storage hole 44 is formed in a substantially rectangular shape extending in the longitudinal direction of the component suction nozzle 3. Support portions 46, which are the upper surfaces of both side edges of the second storage hole 44, support the supported flange portion 14 from the lower surface 14A side.

[0043] The lid portion 50 is a plate-like member disposed on the upper surface side of the base portion 40. The lid portion 50 covers at least a part of the component suction nozzles 1 and 3 stored in the base portion 40 from above by moving in one horizontal direction with respect to the base portion 40. The lid portion 50 has a first insertion hole 52 and a second insertion hole 54 that penetrate from the upper surface to the lower surface.

[0044] The first insertion hole 52 allows the component suction nozzle 1 to be inserted vertically. The first insertion hole 52 includes a wide portion 52A, a narrow portion 52B, and a circular portion 52C. The wide portion 52A is formed at the same position and in the same shape as the wide portion 42A of the first storage hole 42 of the base 40 in a plan view. The narrow portion 52B is formed at the same position and width as the narrow portion 42B of the first storage hole 42 of the base 40 in a plan view. The circular portion 52C is a portion where a part of the narrow portion 52B is expanded into a circular shape so that the supported flange portion 14 of the component suction nozzle 1 can be inserted vertically when the component suction nozzle 1 is stored.

[0045] The second insertion hole 54 allows the component suction nozzle 3 to be inserted vertically. The second insertion hole 54 is formed in a substantially rectangular shape at the same position and width as the second storage hole 44 of the base 40 in a plan view. The second insertion hole 54 includes a circular portion 54A. The circular portion 54A is a portion where a part of the second insertion hole 54 is expanded into a circular shape so that the supported flange portion 14 of the component suction nozzle 3 can be inserted vertically when the component suction nozzle 3 is stored.

[0046] When the lid portion 50 is in the open position shown in FIGS. 5 and 6, the first insertion hole 52 and the second insertion hole 54 of the lid portion 50 are located directly above the first storage hole 42 and the second storage hole 44 of the base 40 in the nozzle storage device 2. At this time, in a plan view, the support portion 46 of the base 40 is exposed in the first insertion hole 52 and the second insertion hole 54 of the lid portion 50.

[0047] In this state, by lowering the component suction nozzle 1 from above toward the first insertion hole 52 and the first storage hole 42 such that the main body portion 10 of the component suction nozzle 1 is in the circular portion 52C of the lid portion 50 and the second beam-shaped portion 26 is along the wide portion 52A, the component suction nozzle 1 passes through the first insertion hole 52 and is stored in the first storage hole 42. The component suction nozzle 1 is supported by the nozzle storage device 2 when the supported flange portion 14 is supported by the support portion 46.

[0048] Further, the main body portion 10 of the component suction nozzle 3 is lowered from above toward the second insertion hole 54 and the second storage hole 44 such that the longitudinal direction of the first beam-like portion 24 is along the longitudinal direction of the second insertion hole 54 in the circular portion 54A of the lid portion 50, so that the component suction nozzle 3 passes through the second insertion hole 54 and is stored in the second storage hole 44. The component suction nozzle 3 is supported by the nozzle storage device 2 by the supported flange portion 14 being supported by the support portion 46.

[0049] When the lid portion 50 moves horizontally from the open position shown in FIGS. 5 and 6 to the closed position shown in FIG. 7 with the component suction nozzles 1 and 3 stored in the nozzle storage device 2, at least a part of the component suction nozzles 1 and 3 stored in the base portion 40 is covered by the lid portion 50 from above.

[0050] More specifically, the positions of the wide portion 52A and the narrow portion 52B of the first insertion hole 52 are shifted with respect to the wide portion 42A and the narrow portion 42B of the first storage hole 42. Thereby, since the lid portion 50 of the portion where the first insertion hole 52 is not open covers a part of the first storage hole 42, the lid portion 50 of the portion where the first insertion hole 52 is not open covers a part of the component suction nozzle 1 stored in the first storage hole 42 from above.

[0051] Also, the position of the circular portion 54A of the second insertion hole 54 is shifted with respect to the main body portion 10 of the component suction nozzle 3 stored in the second storage hole 44. Thereby, since the lid portion 50 of the portion where the second insertion hole 54 is not open covers a part of the second storage hole 44, the lid portion 50 of the portion where the second insertion hole 54 is not open covers a part of the component suction nozzle 3 stored in the second storage hole 44 from above.

[0052] FIG. 8 is a side view showing a standard-sized component suction nozzle 4 according to a comparative example. FIG. 9 is a plan view showing the nozzle storage device 2 with the standard-sized component suction nozzle 4 stored therein. The nozzle storage device 2 can also store a standard-sized component suction nozzle 4.

[0053] The component suction nozzle 4 shown in FIGS. 8 and 9 is different in that, compared with the component suction nozzle 1 of the embodiment, the configuration of the main body portion 10 is the same, it does not have a branch portion 20, and it has only one suction portion 30A.

[0054] The suction portion 30A of the component suction nozzle 4 includes a substantially cylindrical connection shaft portion 34 that is partially inserted into the connection hole portion 16 of the main body portion 10 from below, and a tapered portion 36 having a substantially conical shape including an opening 32 at the tip (lower end).

[0055] The outer peripheral surface of the connection shaft portion 34 and the inner peripheral surface of the connection hole portion 16 are sealed so as to be slidable in the axial direction (vertical direction). The inner peripheral side of the connection shaft portion 34 is a part of the flow path 31 for air to flow through. In a state where the connection shaft portion 34 is inserted into the connection hole portion 16, the internal flow path 31 communicates with the flow path 11 on the inner peripheral side of the main body portion 10 through the connection hole portion 16.

[0056] A coiled compression spring 35 for biasing the suction portion 30A downward with respect to the main body portion 10 is provided on the outer peripheral surface side of the portion of the connection shaft portion 34 that is not inserted into the connection hole portion 16. The compression spring 35 has an upper end in contact with the main body portion 10 from below and a lower end in contact with the tapered portion 36 from above.

[0057] As shown in FIG. 9, the component suction nozzle 4 shown in FIG. 8 is stored at the positions where the component suction nozzles 1 and 3 are stored in FIGS. 6 and 7. Since the nozzle storage device 2 supports the component suction nozzles 1, 3, and 4 by the support portion 46 supporting the supported flange portion 14 of the main body portion 10, the configuration of the main body portion 10 is common, and as long as the other portions have a shape that can be stored in the first storage hole 42 or the second storage hole 44, component suction nozzles 1, 3, and 4 having shapes exemplified so far and other shapes can also be stored.

[0058] [Effect] As described above, the component suction nozzle 1 of the present embodiment includes a main body portion 10 having a flow path 11 therein, a branch portion 20 having a flow path 21 that communicates with the flow path 11 and branches into a plurality of paths therein, and a plurality of suction portions 30 having openings 32 that communicate with the flow path 21. Further, the branch portion 20 is connected to the main body portion 10 and includes a first beam-shaped portion 24 that extends in a horizontal one direction, and a second beam-shaped portion 26 that is connected to the first beam-shaped portion 24 and extends in a horizontal intersection direction orthogonal to the longitudinal direction of the first beam-shaped portion 24. Further, at least two of the plurality of suction portions 30 are attached at positions shifted in the intersection direction of the second beam-shaped portion 26. Thereby, the plurality of suction portions 30 can suck air from the openings 32 and adsorb and hold an electronic component at the tip. Since the component suction nozzle 1 adsorbs and holds an electronic component with the plurality of suction portions 30, it can adsorb and hold a large-sized electronic component.

[0059] Further, the component suction nozzle 1 of the present embodiment includes a supported flange portion 14 in which the main body portion 10 protrudes in a flange shape outward in the horizontal direction at a position below the portion mounted on the shaft S. The nozzle storage device 2 of the present embodiment has a storage hole (first storage hole 42) in which the first beam-shaped portion 24 and the second beam-shaped portion 26 of the component suction nozzle 1 can be stored from above, and supports the supported flange portion 14 at the edge (support portion 46) of the storage hole. Thereby, as long as the configuration of the main body portion 10 is common and the other portions are in a shape that can be stored in the storage hole (first storage hole 42), component suction nozzles having different shapes of the first beam-shaped portion 24 and the second beam-shaped portion 26 or standard sizes that do not include these can also be stored.

[0060] [Other Embodiments] Although the embodiments of the present application have been described above, the present invention is not limited by the contents of these embodiments. The above-described embodiments and modified examples can be appropriately combined as long as the processing contents do not conflict. Further, the above-described components include those that can be easily assumed by those skilled in the art, those that are substantially the same, and those within a so-called equivalent range. Furthermore, the above-described components can be appropriately combined. Furthermore, various omissions, substitutions, or changes of the components can be made without departing from the gist of the above-described embodiments.

[0061] For example, in the component suction nozzle 1 of the embodiment, the first beam-shaped portion 24 and the second beam-shaped portion 26 are such that the branch portion 20 is formed in an H shape in plan view, and the suction portion 30 has a total of six, three in the longitudinal direction of the second beam-shaped portion 26 each. However, the shape of the branch portion 20 in plan view and the arrangement of the suction portion 30 are not limited to the state of the embodiment.

[0062] FIG. 10 is a bottom view showing the component suction nozzle 1A according to the first modification. The component suction nozzle 1A of the first modification is different from the component suction nozzle 1 of the embodiment in that it has a pair of second beam-shaped portions 26A instead of a pair of second beam-shaped portions 26.

[0063] The second beam-shaped portion 26 of the embodiment was orthogonal to the first beam-shaped portion 24 and extended in a horizontal direction, and was connected to both ends of the first beam-shaped portion 24 at the side surfaces of the central portion in the longitudinal direction. In contrast, the second beam-shaped portion 26 of the first modification is orthogonal to the first beam-shaped portion 24 and extends in a horizontal direction, and is connected to both ends of the first beam-shaped portion 24 at the side surface of one end in the longitudinal direction. That is, the first beam-shaped portion 24 and the pair of second beam-shaped portions 26A are provided in a U shape in plan view.

[0064] Also, in the first modification, two suction portions 30 are respectively arranged at positions where the first beam-shaped portion 24 and the pair of second beam-shaped portions 26 intersect, and one is arranged at each end of each second beam-shaped portion 26 on the side opposite to the end connected to the first beam-shaped portion 24 in the longitudinal direction, for a total of four arranged.

[0065] FIG. 11 is a bottom view showing the component suction nozzle 1B according to the second modification. The component suction nozzle 1B of the second modification is different from the component suction nozzle 1A of the first modification in that it has one beam end portion 26B instead of one of the pair of second beam-shaped portions 26A.

[0066] The beam end portion 26B of the second modification example is a portion that connects to the end portion on the side opposite to the end portion that connects to the second beam-shaped portion 26A of the first beam-shaped portion 24. The beam end portion 26B is in a state where the second beam-shaped portion 26A extends in a direction orthogonal to the longitudinal direction of the first beam-shaped portion 24, and suction portions 30 are provided at respective end portions, whereas only one suction portion 30 is provided on the extension of the first beam-shaped portion 24. That is, the first beam-shaped portion 24, the second beam-shaped portion 26A, and the beam end portion 26B are provided in an L shape in plan view.

[0067] As shown in the component suction nozzle 1 of the embodiment, the component suction nozzle 1A of the first modification example, and the component suction nozzle 1B of the second modification example, the component suction nozzles 1, 1A, 1B of the present invention may have at least a first beam-shaped portion 24 extending in at least one horizontal direction and at least one second beam-shaped portion 26 extending in an intersecting direction orthogonal to the longitudinal direction of the first beam-shaped portion 24.

[0068] Further, in the state where at least two of the plurality of suction portions 30 are arranged at positions shifted from each other in the intersecting direction of the second beam-shaped portion 26. The suction portion 30 may be provided also on the first beam-shaped portion 24, or four or more may be provided on one second beam-shaped portion 26, or two or more rows may be provided on one second beam-shaped portion 26.
