DETAILED DESCRIPTION

[0010] Hereinafter, the embodiments are described with reference to the accompanying drawings. In addition, the present invention is not limited to the following modes for implementing the invention (hereinafter referred to as embodiments). In addition, the constituent elements of the following embodiments include elements that can be easily thought of by a person skilled in the art, substantially the same elements, i.e., elements of the so-called equal range. Furthermore, the constituent elements disclosed in the following embodiments can be appropriately combined.

[0011] (Installation device) Figure 1 1 is a top view schematically showing the general structure of a mounting device 100 equipped with a component adsorption nozzle 1 and a nozzle storage device 2 according to an embodiment. Figure 1, the X-axis is a horizontal direction, and the Y-axis is a horizontal direction orthogonal to the X-axis. The mounting device 100 is a device for mounting electronic components on a substrate P. The mounting device 100 includes a base member 101, a substrate conveying device 102, a component supply device 103, a mounting head 104, a head moving device 105, a component state detection unit 106, a nozzle replacement unit 107, and a component storage unit 108.

[0012] The base member 101 supports 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 replacement unit 107 , and the component storage unit 108 .

[0013] The substrate conveying device 102 conveys the substrate P supplied to the mounting device 100 to the mounting area DM where the electronic components are mounted through the mounting head 104. The mounting area DM is defined on the conveying path of the substrate conveying device 102. In an embodiment, the substrate conveying device 102 conveys the substrate P along the X-axis direction. The substrate P before the electronic components are mounted is moved into the substrate conveying device 102 from the end on the -X side of the base member 101. The substrate conveying device 102 conveys the moved-in substrate P in the +X direction and stops in the mounting area DM. The mounting head 104 mounts electronic components on the surface of the substrate P arranged in the mounting area DM. The substrate conveying device 102 conveys the substrate P after the electronic components are mounted in the +X direction. The substrate P after the electronic components are mounted is moved out from the end on the +X side 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. A plurality of tape feeders are arranged in the X-axis direction. The supply area SM for electronic components is defined on the tape feeder. The tape feeder transports a carrier tape that holds a plurality of electronic components. By transporting the carrier tape, at least one of the plurality of electronic components is supplied to the supply area SM. In an embodiment, the component supply device 103 is arranged on both the +Y side and the -Y side of the substrate conveying device 102. In addition, the component supply device 103 may also be arranged on one of the +Y side and the -Y side of the substrate conveying device 102.

[0015] The mounting head 104 holds the electronic components supplied from the component supply device 103 by means of a component suction nozzle 1 described later and mounts them on the substrate P. The mounting head 104 may also have a plurality of component suction nozzles 1. The mounting head 104 is capable of moving between a supply area SM to which electronic components are supplied and a 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 by means of a component suction nozzle 1, and after moving to the mounting area DM, mounts the electronic components on the substrate P arranged in the mounting area DM.

[0016] The head moving device 105 can move the mounting head 104 in 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 in the movable area of ​​the mounting head 104, on the vertical lower side 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 where the electronic components are mounted on the substrate P and the supply area SM where the electronic components for mounting on the substrate P are supplied.

[0018] The component state detection unit 106 is an image recognition device having a camera for capturing images of the vicinity of the component adsorption nozzle 1 of the mounting head 104 and a lighting unit for illuminating the captured area. The component state detection unit 106 recognizes the shape of the electronic component adsorbed by the component adsorption nozzle 1 of the mounting head 104 and the holding state of the electronic component by the component adsorption nozzle 1.

[0019] The nozzle replacement unit 107 includes a 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 installed on the mounting head 104, and the component suction nozzle 1 installed on the mounting head 104 is stored in the nozzle storage device 2. The mounting head 104 changes the component suction nozzle 1 installed by the nozzle replacement unit 107, supplies air pressure to the installed component suction nozzle 1, and drives it, thereby being able to hold the held electronic component under appropriate conditions (suction or gripping).

[0020] The component storage section 108 is a box for storing electronic components that are held by the mounting head 104 through the component suction nozzle 1 described later and are not mounted on the substrate P. That is, in the mounting device 100, it becomes a discard box for discarding electronic components that are not mounted on the substrate P. When there are electronic components that are not 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 section 108 and releases the held electronic components, thereby putting the electronic components into the component storage section 108.

[0021] (Parts suction nozzle) Figure 2 It is a perspective view showing the component adsorption nozzle 1 according to the embodiment. Figure 3 It is a bottom view showing the component adsorption nozzle 1 according to the embodiment. Figure 4 yes Figure 3 AA cross-sectional view shown. The component suction nozzle 1 is a component that can be detachably mounted on the lower end of the shaft S in the mounting device 100 for mounting electronic components on the substrate P, and is used to absorb and hold the electronic components. The shaft S is supported so as to be able to rise and fall relative to the mounting head 104 and to be able to rotate around the axis. It is assumed that the component suction nozzle 1 of the embodiment is used in the installation of large electronic components that are difficult to be absorbed and held by a component suction nozzle of a standard size. The component suction nozzle 1 has a main body 10, a branch portion 20, and a plurality of suction portions 30.

[0022] The main body 10 is mounted on a mounting head 104 mounted on a mounting device 100 via a shaft S. The main body 10 is formed as a whole into a substantially cylindrical shape extending in the vertical direction. The inner peripheral side of the main body 10 is a flow path 11 for air circulation. One end of the flow path 11 is connected to an axial flow path formed on the shaft S, and the other end is connected to one end of a flow path 21 of a branch portion 20 described later. The main body 10 includes: a gripped portion 12 gripped by the lower end of the shaft S; a nozzle storage device 2 described later (see Figure 5 and a connecting hole portion 16 connecting the branch portion 20.

[0023] The gripped portion 12 is located at the upper portion of the main body 10 and is mounted on the lower end portion of the shaft S. Figure 2 In the embodiment shown, it is formed by arranging a plurality of substantially cylindrical portions and substantially truncated cone portions having different outer diameters in the axial direction (vertical direction). In addition, when the gripped portion 12 is mounted on the shaft S, it is fixed to the inner circumference of the shaft S in the embodiment. In addition, the shape of the gripped portion 12 and the way of engaging with the shaft S can be the same as other component adsorption nozzles mounted on the mounting device 100 of the same model, for example, it can also be a form that matches the shaft S, covers the lower end of the shaft S from the outer circumference and is fixed to the outer circumference.

[0024] The supported flange portion 14 is formed in a generally annular shape and protrudes radially (horizontally) outwardly in a flange-like manner at a position below the gripping portion 12 of the generally cylindrical main body portion 10. The supported flange portion 14 is a portion supported by the support portion 46 from the lower surface 14A side when the component suction nozzle 1 is stored in the nozzle storage device 2 described later (see Figure 5 and Figure 6 ). In other words, the component adsorption 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 16 is a hole or a recessed portion formed upward from the lower end surface 10A of the substantially cylindrical main body 10. The connection hole 16 is a part of the flow path 11, and communicates with the flow path 11 formed inside the grasped portion 12 at the bottom surface, that is, the upper end surface. The connection shaft portion 22 of the branch portion 20 is mounted in the connection hole 16.

[0026] The branch portion 20 is a component connected to the main body 10 and used to install a plurality of adsorption portions 30. The branch portion 20 has a flow path 21 formed inside for air circulation. One end of the flow path 21 is connected to the other end of the flow path 11 of the main body 10, and branches toward the other end into a plurality of flow paths and connected to a plurality of adsorption portions 30. The branch portion 20 is installed on the main body 10 at the lower side of the main body 10 in a manner that it can be raised and lowered in the vertical direction relative to the main body 10. In addition, the branch portion 20 is forced downward relative to the main body 10. The branch portion 20 includes a connecting shaft portion 22, a first beam-shaped portion 24, and a pair of second beam-shaped portions 26.

[0027] The connecting shaft portion 22 constitutes the upper portion of the branch portion 20, and is a roughly cylindrical portion extending in the axial direction (vertical direction), and a portion thereof is inserted from below into the connecting hole portion 16 of the main body portion 10. The outer peripheral surface of the connecting shaft portion 22 and the inner peripheral surface of the connecting hole portion 16 are sealed in a manner that allows sliding in the axial direction (vertical direction). The inner peripheral side of the connecting shaft portion 22 is a portion of the flow path 21 for air circulation. When the connecting shaft portion 22 is inserted into the connecting hole portion 16, the internal flow path 21 is connected to the flow path 11 on the inner peripheral side of the main body portion 10 via the connecting hole portion 16.

[0028] In the embodiment, a helical compression spring 23 for biasing the branch portion 20 downward relative to the main body 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 is in contact with the main body 10 from below, and the lower end is in contact with the first beam-shaped portion 24 from above.

[0029] The first beam-shaped portion 24 is located below the main body 10 and the connecting shaft portion 22, and is a plate-shaped or rod-shaped portion extending in one horizontal direction and connected to the lower end of the connecting shaft portion 22 at the upper surface of the center portion in the longitudinal direction. Inside the first beam-shaped portion 24, the flow path 21 includes: a flow path 21A communicating with the flow path 21 in the connecting shaft portion 22; and flow paths 21B, 21B branching from the flow path 21A in the longitudinal direction.

[0030] The pair of second beam-shaped portions 26 are plate-shaped or rod-shaped portions extending in the horizontal direction and perpendicular to the first beam-shaped portion 24, and connected to both ends of the first beam-shaped portion 24 at the side surface of the center portion in the longitudinal direction. That is, the first beam-shaped portion 24 and the pair of second beam-shaped portions 26 are arranged in an H shape in a plan view.

[0031] A plurality of (three in each embodiment) adsorption 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 adsorption portion 30 is arranged in each of the plurality of recesses 28 provided on the lower surface side of the second beam-shaped portion 26 to divide each adsorption portion 30.

[0032] Inside each second beam-shaped portion 26, the flow path 21 includes: flow paths 21C and 21C branching from the flow path 21B branching from the first beam-shaped portion 24 in each direction along the length direction of the second beam-shaped portion 26; and flow path 21D extending vertically downward from the flow paths 21C and 21C and communicating with each adsorption portion 30. That is, in the embodiment, the flow path 21 is branched into two in the first beam-shaped portion 24, and is branched into three in each second beam-shaped portion 26, for a total of six branches.

[0033] The adsorption portion 30 is a member for adsorbing and holding electronic components. The adsorption portion 30 is a generally cylindrical shape extending in the vertical direction, and has an opening 32 at the front end (lower end) that is connected to the other end of the flow path 21 of the branch portion 20. The component adsorption nozzle 1 adsorbs and holds the electronic component at the front end by sucking air from the opening 32 of the adsorption portion 30. The adsorption portion 30 is provided on the lower surface side of the branch portion 20. The upper end of the adsorption portion 30 of the embodiment is fixed to the recess 28 of the second beam-shaped portion 26 and is connected to the flow path 21D.

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

[0035] As described above, the main body 10 is mounted on the shaft S, and the component suction nozzle 1 is mounted on the mounting head 104 of the mounting device 100 via the shaft S. A vacuum pressure supply mechanism (not shown) on the mounting head 104 side supplies vacuum pressure via the flow path formed in the shaft S, thereby forming an airflow from the opening 32 of the suction portion 30 toward the flow paths 21D, 21C, 21B, 21A of the branch portion 20, the flow path 11 of the main body 10, and the shaft S in the component suction nozzle 1. As a result, the suction portion 30 can suck air from the opening 32 and suction and hold the electronic component at the front end. The component suction nozzle 1 of the embodiment suctions and holds the electronic component through a plurality of suction portions 30, and thus can suction and hold large electronic components.

[0036] (Nozzle storage device) Figure 5 It is a top view which shows the nozzle storage device 2 which concerns on embodiment. Figure 6 and Figure 7 FIG. 2 is a top view of a nozzle storage device 2 in which component suction nozzles 1 and 3 are stored. The nozzle storage device 2 is used to automatically control the suction nozzles 1 and 3. Figures 2 to 4 The component suction nozzle 1 shown is a device for detaching the component suction nozzle 1 from the mounting head 104 and storing the component suction nozzle 1. The nozzle storing device 2 is arranged in the movable area of ​​the mounting head 104 where the component suction nozzle 1 is mounted. Figure 1 The nozzle replacement unit 107 is shown.

[0037] The nozzle storage device 2 is configured to support the supported flange portion 14 of the nozzle 1 from the lower surface 14A side. In the embodiment, the nozzle storage device 2 includes: a base 40 for receiving the component and sucking the nozzle 1 from above; and a cover 50 for covering at least a part of the component stored in the base 40 and sucking the nozzle 1 from above.

[0038] The base 40 can be fixedly provided on, for example, a base member 101 of a mounting device 100 equipped with a mounting head 104 for mounting the component adsorption nozzle 1. The base 40 has a first receiving hole 42 and a second receiving hole 44 formed downward from the upper surface.

[0039] In the first receiving hole 42, the receiving component sucks the nozzle 1 from above. Figure 6 As shown, in the first storage hole 42 of the embodiment, three component suction nozzles 1 are arranged in one direction. At this time, the direction in which the component suction nozzles 1 are arranged is parallel to the length direction of the first beam-shaped portion 24 of the component suction nozzle 1.

[0040] The first storage hole 42 includes a wide portion 42A for storing the second beam-shaped portion 26 and a narrow portion 42B for storing the first beam-shaped portion 24 in a manner that forms an H-shaped shape formed by the first beam-shaped portion 24 and the second beam-shaped portion 26 of the component suction nozzle 1 in a plan view. The first storage hole 42 of the embodiment is formed in a shape of three H letters connected to each other 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 10, and is larger than the maximum width of the lower part of the supported flange portion 14 including the first beam-shaped portion 24. The upper surfaces of the two side edges of the narrow portion 42B, i.e., the supporting portion 46, support the supported flange portion 14 from the lower surface 14A side.

[0041] The second storage hole 44 stores the component suction nozzle 3 from above. Figures 2 to 4 Compared with the component adsorption nozzle 1 in which the adsorption portion 30 is arranged in an H shape in the embodiment shown in the figure, it is different in that the second beam-shaped portion 26 is not provided and the adsorption portions 30 are arranged at both ends of the first beam-shaped portion 24. Figure 6 As shown, in the second storage hole 44 of the embodiment, three component suction nozzles 3 are arranged and stored 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] The second storage hole 44 is formed in a substantially rectangular shape in a plan view extending along the longitudinal direction of the component suction nozzle 3. The upper surfaces of both side edges of the second storage hole 44, namely, the support portions 46, support the supported flange portion 14 from the lower surface 14A side.

[0043] The cover 50 is a plate-shaped member disposed on the upper surface side of the base 40. The cover 50 covers at least a portion of the component suction nozzles 1 and 3 stored in the base 40 from above by moving in one horizontal direction relative to the base 40. The cover 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 component adsorption nozzle 1 can be inserted into the first insertion hole 52 along the vertical direction. 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 in the same position and shape as the wide portion 42A of the first storage hole 42 of the base 40 when viewed from above. The narrow portion 52B is formed in the same position and width as the narrow portion 42B of the first storage hole 42 of the base 40 when viewed from above. The circular portion 52C is a portion in which a part of the narrow portion 52B is expanded into a circular shape when the component adsorption nozzle 1 is stored so that the supported flange portion 14 of the component adsorption nozzle 1 can be inserted along the vertical direction.

[0045] The component suction nozzle 3 can be inserted into the second insertion hole 54 along the vertical direction. 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 that expands a portion of the second insertion hole 54 into a circular shape when the component suction nozzle 3 is stored so that the supported flange portion 14 of the component suction nozzle 3 can be inserted along the vertical direction.

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

[0047] In this state, the component suction nozzle 1 is lowered from above toward the first insertion hole 52 and the first storage hole 42 in such a manner that the main body 10 of the component suction nozzle 1 follows the circular portion 52C of the cover portion 50 and the second beam-shaped portion 26 follows the wide portion 52A, thereby the component suction nozzle 1 is received in the first storage hole 42 through the first insertion hole 52. The component suction nozzle 1 is supported by the nozzle receiving device 2 by the supported flange portion 14 being supported by the supporting portion 46.

[0048] Furthermore, the component suction nozzle 3 is lowered from above toward the second insertion hole 54 and the second storage hole 44 in such a manner that the main body 10 of the component suction nozzle 3 is along the circular portion 54A of the cover portion 50 and the length direction of the first beam-shaped portion 24 is along the length direction of the second insertion hole 54, thereby the component suction nozzle 3 is stored in the second storage hole 44 through the second insertion hole 54. 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] The nozzle storage device 2 is in a state where the component suction nozzles 1 and 3 are stored, and the cover 50 is opened from the Figure 5 and Figure 6 The open position shown is moved horizontally to Figure 7 In the closed position shown, the cover 50 covers at least a portion of the component suction nozzles 1 and 3 accommodated in the base 40 from above.

[0050] More specifically, the positions of the wide portion 52A and the narrow portion 52B of the first insertion hole 52 are offset relative to the wide portion 42A and the narrow portion 42B of the first receiving hole 42. Thus, since the portion of the cover 50 that does not have the first insertion hole 52 covers a portion of the first receiving hole 42, the portion of the cover 50 that does not have the first insertion hole 52 covers a portion of the component suction nozzle 1 received in the first receiving hole 42 from above.

[0051] In addition, the position of the circular portion 54A of the second insertion hole 54 is offset relative to the main body 10 of the component suction nozzle 3 stored in the second storage hole 44. Therefore, since the portion of the cover 50 where the second insertion hole 54 is not formed covers a portion of the second storage hole 44, the portion of the cover 50 where the second insertion hole 54 is not formed covers a portion of the component suction nozzle 3 stored in the second storage hole 44 from above.

[0052] Figure 8 It is a side view of the component adsorption nozzle 4 showing a standard size in proportion. Fig. 9 1 is a plan view of the nozzle storage device 2 showing a state in which the component suction nozzles 4 of standard sizes are stored. The nozzle storage device 2 can also store the component suction nozzles 4 of standard sizes.

[0053] Figure 8 and Fig. 9 The component suction nozzle 4 shown has the same structure of the main body 10 as the component suction nozzle 1 of the embodiment, but is different in that it does not have the branch portion 20 and has only one suction portion 30A.

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

[0055] The outer circumferential surface of the connecting shaft portion 34 and the inner circumferential surface of the connecting hole portion 16 are sealed in a manner that allows sliding in the axial direction (vertical direction). The inner circumferential side of the connecting shaft portion 34 is a part of the flow path 31 for air circulation. When the connecting shaft portion 34 is inserted into the connecting hole portion 16, the internal flow path 31 communicates with the flow path 11 on the inner circumferential side of the main body portion 10 via the connecting hole portion 16.

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

[0057] like Fig. 9 As shown, in Figure 6 and Figure 7 The position where the parts suction nozzles 1 and 3 are stored is stored Figure 8 The nozzle storage device 2 supports the component suction nozzles 1, 3, and 4 by supporting the supported flange portion 14 of the main body 10 through the support portion 46. Therefore, as long as the structure of the main body 10 is common and the other parts can be stored in the first storage hole 42 or the second storage hole 44, it is also possible to store components other than the component suction nozzles 1, 3, and 4 of the shapes exemplified so far.

[0058] (Effect) As described above, the component suction nozzle 1 of the present embodiment includes: a main body 10 having a flow path 11 inside; a branch portion 20 connected to the flow path 11 and having a flow path 21 branched into a plurality of branches inside; and a plurality of suction portions 30 having an opening 32 connected to the flow path 21. In addition, the branch portion 20 includes: a first beam-shaped portion 24 connected to the main body 10 and extending in one horizontal direction; and a second beam-shaped portion 26 connected to the first beam-shaped portion 24 and extending in a horizontal cross direction orthogonal to the length direction of the first beam-shaped portion 24. In addition, at least two of the plurality of suction portions 30 are mounted at positions staggered in the cross direction of the second beam-shaped portion 26. Thus, the plurality of suction portions 30 suck air from the opening 32, and can suction and hold electronic components at the front end. The component suction nozzle 1 suctions and holds electronic components through the plurality of suction portions 30, and thus can suction and hold large electronic components.

[0059] In addition, the component suction nozzle 1 of the present embodiment includes a supported flange portion 14, and the supported flange portion 14 is formed by the main body 10 protruding outward in a flange shape in the horizontal direction at a position lower than the portion installed on the shaft S. The nozzle storage device 2 of the present embodiment has a storage hole (first storage hole 42) that can store the first beam-shaped portion 24 and the second beam-shaped portion 26 of the component suction nozzle 1 from above, and the supported flange portion 14 is supported by the edge of the storage hole (support portion 46). Therefore, as long as the structure of the main body 10 is common and the other parts can be stored in the storage hole (first storage hole 42), it is also possible to store component suction nozzles with different shapes of the first beam-shaped portion 24 and the second beam-shaped portion 26, or component suction nozzles of standard sizes that do not have these.

[0060] (Other embodiments) Above, the embodiments of the present application have been described, but the present invention is not limited by the contents of these embodiments. The above embodiments and variations can be appropriately combined within the scope of not making the processing content contradictory. In addition, the above constituent elements include elements that are easily thought of by those skilled in the art, substantially the same elements, and elements of so-called equal scope. Furthermore, the above constituent elements can be appropriately combined. In addition, various omissions, substitutions or changes of constituent elements can be performed without departing from the scope of the above embodiments.

[0061] For example, the component adsorption nozzle 1 of the embodiment is constructed such that the branch portion 20 is formed into an H-shape in a plan view by a first beam-shaped portion 24 and a second beam-shaped portion 26, and has three adsorption portions 30 respectively in the length direction of the second beam-shaped portion 26, for a total of six adsorption portions 30, but the plan view shape of the branch portion 20 and the configuration of the adsorption portions 30 are not limited to the form of the embodiment.

[0062] Fig.10 1A is a bottom view showing a component suction nozzle 1A of a 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 includes a pair of second beam-shaped portions 26A instead of the pair of second beam-shaped portions 26 .

[0063] The second beam-shaped portion 26 of the embodiment is in the form of being orthogonal to the first beam-shaped portion 24, extending in the horizontal direction, and connected to both ends of the first beam-shaped portion 24 at the side of the center portion in the longitudinal direction. In contrast, the second beam-shaped portion 26 of the first modified example is in the form of being orthogonal to the first beam-shaped portion 24, extending in the horizontal direction, and connected to both ends of the first beam-shaped portion 24 at the side of one end portion 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 a plan view.

[0064] In addition, in the first modified example, one adsorption portion 30 is arranged at each intersection of the first beam-shaped portion 24 and the pair of second beam-shaped portions 26A, and one adsorption portion 30 is arranged at each end of the second beam-shaped portion 26A in the longitudinal direction and on the opposite side of the end connected to the first beam-shaped portion 24, and a total of four adsorption portions 30 are arranged.

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

[0066] The beam end 26B of the second modified example is a portion connected to the end of the first beam-shaped portion 24 on the opposite side of the end connected to the second beam-shaped portion 26A. While the second beam-shaped portion 26A is extended in a direction perpendicular to the longitudinal direction of the first beam-shaped portion 24 and has an adsorption portion 30 at each end, the beam end 26B is provided with only one adsorption portion 30 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 26B are provided in an L-shape in a plan view.

[0067] As shown in the component suction nozzle 1 of the embodiment, the component suction nozzle 1A of the first variant and the component suction nozzle 1B of the second variant, the component suction nozzle 1, 1A, 1B of the present invention only needs to have at least a first beam-shaped portion 24 extending in a horizontal direction and at least one second beam-shaped portion 26 extending in a cross direction orthogonal to the length direction of the first beam-shaped portion 24.

[0068] In addition, the plurality of adsorption portions 30 are in the following form: at least two are arranged at positions staggered from each other in the cross direction of the second beam-shaped portion 26. The adsorption portion 30 may be provided on the first beam-shaped portion 24, four or more adsorption portions 30 may be provided on one second beam-shaped portion 26, or two or more rows of adsorption portions 30 may be provided on one second beam-shaped portion 26.
