[0035] Fig. 2 is a schematic perspective view of an example of the component supply device 1 according to the first embodiment of the present disclosure. Fig. 2 is a schematic front view of the example of the component supply device 1 according to the first embodiment of the present disclosure. Fig. 3 is a control block diagram of the example of the component supply device 1 according to the first embodiment of the present disclosure.
[0036] 2 and 3, the component supplying device 1 includes a main body 2, a component alignment unit 3, an agitation unit 4, and a cassette holding unit 5. The component supplying device 1 also includes a component conveying path 6 and an agitating air supply path 7.

[0037] In the example shown in FIGS. 2 and 3, the component supplying device 1 includes a component conveying tube 9 that constitutes a part of the component conveying path 6, and an agitating air supply tube 10 that constitutes a part of the agitating air supply path 7.
[0038] 2 and 3, a component storage cassette 12 is attached to the cassette holder 5. A notification lamp 13 is disposed on the side of the mixing unit 4.
[0039] The component supply device 1 mixes the components stored in the component storage cassette 12 using the mixing unit 4, and aligns the components in a line using the component alignment unit 3. The component supply device 1 transports the aligned components to the component supply position P1 via the component transport path 6. The component supply position P1 is a position where a component supply opening 2a is provided on the top surface of the main body 2, and is a position where components are picked up by the component transfer unit 101. The components transported to the component supply position P1 are picked up by the component transfer unit 101 and mounted, for example, at a predetermined position on the board 120.
[0040] In the component supply device 1, air is used to agitate the plurality of components. The air used for agitation is supplied to the component alignment unit 3 via an agitation air supply path 7.
[0041] The component storage cassette 12 stores a plurality of components, all of which have the same size and shape.
[0042] Each of the components of the component supplying device 1 will now be described in detail.
[0043] <Main body> The main body 2 is the main body portion of the component supply device 1. A component supply opening 2a is provided on the top surface of the main body 2 at a position corresponding to the component supply position P1 to which multiple components are transported. When a component is transported to the component supply position P1, the component is exposed from the component supply opening 2a. The component transfer unit 101 picks up the component placed at the component supply position P1 from the component supply opening 2a of the main body 2.
[0044] The main body 2 has a mechanism for generating air for stirring and transporting. Specifically, as shown in Fig. 3, the main body 2 has a control unit 20, an air introduction path 21, a first stirring air supply path 22, a stirring air control valve 24, an air suction path 26, and a suction air control valve 27.
[0045] The main body 2 also has a mechanism for sequentially picking up components from the plurality of components conveyed along the component conveying path 6 and moving them to the component supply position P1. Specifically, as shown in Figures 2 and 3, the main body 2 has a wheel 90, a wheel holding unit 91, a wheel driving unit 92, and a negative pressure introduction path 93.
[0046] The control unit 20 controls each component of the component supply device 1. The control unit 20 can be realized using semiconductor elements or the like. The control unit 20 can be configured with, for example, a microcomputer, a CPU, an MPU, a GPU, a DSP, an FPGA, or an ASIC. The functions of the control unit 20 may be configured using hardware alone, or may be realized by combining hardware and software. The control unit 20 realizes predetermined functions by reading data and programs stored in a storage unit such as a memory and performing various arithmetic processing.
[0047] The air introduction path 21 introduces compressed air from an air introduction port 21a provided on the side surface of the main body 2. The air introduction path 21 is connected to a first agitation air supply path 22 inside the main body 2 via an agitation air control valve 24. For example, the air introduction path 21 is formed by piping. Furthermore, a pump that supplies compressed air may be connected to the air introduction port 21a.
[0048] The first agitation air supply path 22 is a flow path that supplies air to the component alignment unit 3. The first agitation air supply path 22 is connected to the agitation air supply tube 10, and constitutes a part of the agitation air supply path 7. For example, the first agitation air supply path 22 is constituted by piping.
[0049] The agitation air control valve 24 controls the air flowing through the first agitation air supply path 22. For example, when the agitation air control valve 24 is opened, air is supplied to the component alignment unit 3 through the first agitation air supply path 22 and the agitation air supply tube 10. When the agitation air control valve 24 is closed, air is no longer supplied to the component alignment unit 3 through the first agitation air supply path 22 and the agitation air supply tube 10.
[0050] The air suction path 26 is a flow path that sucks in air. In the air suction path 26, air is sucked in from an air suction port 26a provided on the side surface of the main body 2. The air suction path 26 is connected to a negative pressure introduction path 93. For example, the air suction path 26 is formed by piping. Furthermore, a pump that sucks in air may be connected to the air suction port 26a.
[0051] The component supplying device 1 can create a negative pressure in the negative pressure introduction path 93 by sucking air from the air suction path 26.
[0052] A suction air control valve 27 is disposed in the air suction path 26 .
[0053] The suction air control valve 27 controls the air flowing through the air suction path 26. For example, when the suction air control valve 27 opens, air is sucked into the air suction path 26, creating a negative pressure. When the suction air control valve 27 closes, air is no longer sucked into the air suction path 26.
[0054] 4 is a control block diagram of an example of the component mounting device 100 according to the first embodiment of the present disclosure. As shown in FIG. 4, the control unit 20 of the component supply device 1 has, as functional components, an agitation processing unit 28 and a wheel control unit 29. The agitation processing unit 28 controls the agitation air control valve 24. The wheel control unit 29 controls the suction air control valve 27 and the wheel drive unit 92.
[0055] The control unit 20 may control the notification lamp 13 based on the detection result of the component detection sensor 14. The component detection sensor 14 will be described later.
[0056] 4, the component mounting device 100 includes a main control unit 104. The main control unit 104 controls the component supply devices 1 and the component transfer unit 101.
[0057] The main control unit 104 can be realized by semiconductor elements or the like. The main control unit 104 can be configured by, for example, a microcomputer, a CPU, an MPU, a GPU, a DSP, an FPGA, or an ASIC. The functions of the main control unit 104 may be configured by hardware alone, or may be realized by combining hardware and software. The main control unit 104 realizes predetermined functions by reading data and programs stored in a storage unit such as a memory and performing various arithmetic processing.
[0058] Next, the component alignment unit 3 and the mixing unit 4 will be described with reference to Figures 5 to 7. Figure 5 is a schematic cross-sectional view taken along line AA in Figure 2. Figure 6 is a schematic cross-sectional view taken along line BB in Figure 3. Figure 7 is a schematic cross-sectional view taken along line CC in Figure 3.
[0059] <Parts Alignment Section> The component alignment unit 3 is a unit that aligns a plurality of components. The component alignment unit 3 aligns the mixed components in a line.
[0060] 5 and 6, a rotor 30 is arranged in the component alignment unit 3. Specifically, the component alignment unit 3 has a rotor storage chamber 34 that stores the rotor 30. The rotor storage chamber 34 stores the rotor 30 in a rotatable manner. The component alignment unit 3 supplies air to the rotor storage chamber 34 to rotate the rotor 30.
[0061] The rotor 30 is provided with through holes 31 that allow multiple components to pass through in a line in the vertical direction. In this specification, the "vertical direction" refers to the vertical direction, or the Z direction. In the example shown in Fig. 5, the through holes 31 include a first through hole 31a and a second through hole 31b.
[0062] The first through-hole 31a guides the multiple components introduced through the component introduction port 41 of the mixing unit 4 to the second through-hole 31b. The second through-hole 31b aligns the multiple components in a vertical line and discharges them onto the component conveying path 6.
[0063] The first through hole 31a is a hole that extends in the vertical direction and opens toward the component insertion port 41. The second through hole 31b is a hole that communicates with the first through hole 31a, extends in the vertical direction, and opens toward the component conveying path 6. That is, the opening of the first through hole 31a is formed in the upper surface of the rotor 30, and the opening of the second through hole 31b is formed in the lower surface of the rotor 30.
[0064] The opening of the first through hole 31a is larger than the opening of the second through hole 31b when viewed from the top-bottom direction, and the first through hole 31a becomes smaller from the component insertion port 41 toward the second through hole 31b. That is, the diameter of the first through hole 31a becomes smaller toward the second through hole 31b. The second through hole 31b has a constant diameter from the portion connected to the first through hole 31a to the opening on the bottom surface of the rotor 30. That is, the diameter of the second through hole 31b is constant.
[0065] The diameter of the second through hole 31b is designed to allow multiple components to pass through one by one. For example, if the component has a longitudinal direction and a lateral direction, the diameter of the second through hole 31b is larger than the lateral direction and smaller than the longitudinal direction.
[0066] The through-hole 31 is defined by a rotor inner wall 31c. The rotor inner wall 31c rotates together with the rotor 30. The rotor inner wall 31c is also a portion that comes into contact with multiple components. Therefore, the multiple components are guided through the through-hole 31 by coming into contact with the rotor inner wall 31c. When the rotor inner wall 31c comes into contact with the multiple components while rotating, a force is applied to the multiple components in the rotational direction of the rotor 30, which makes it easy to agitate the multiple components.
[0067] In the first through-hole 31a, the rotor inner wall 31c is formed as an inclined surface. Specifically, the rotor inner wall 31c is formed in a tapered shape. In the second through-hole 31b, the rotor inner wall 31c is formed as a wall surface extending in the vertical direction.
[0068] The rotor 30 has a rotor body 32 and a plurality of blades 33 .
[0069] The rotor body 32 is a portion in which the through hole 31 is provided. The rotor body 32 has, for example, a cylindrical shape. When viewed from the height direction (Z direction) of the component supply device 1, the through hole 31 is provided at the center of the rotor body 32.
[0070] The plurality of blades 33 are provided on the outer periphery of the rotor main body 32. As shown in Fig. 6, when viewed from the height direction (Z direction) of the component supply device 1, the plurality of blades 33 are provided radially at equal intervals on the outer periphery of the rotor main body 32. For example, the plurality of blades 33 have a plate shape.
[0071] The plurality of blades 33 receive air supplied from the agitating air supply passage 7. This allows the rotor 30 to rotate.
[0072] The rotor storage chamber 34 stores the rotor 30 so that it can rotate horizontally around a central axis CX1 that extends through the through-hole 31 in the vertical direction. The rotor storage chamber 34 is formed as a recess having an opening on the upper surface of the component alignment unit 3. Specifically, the rotor storage chamber 34 is formed as a cylindrically recessed recess. When viewed from the height direction (Z direction) of the component supplying device 1, the rotor storage chamber 34 has a circular shape and is larger than the outer shape of the rotor 30. Furthermore, when viewed from the height direction (Z direction) of the component supplying device 1, the depth of the rotor storage chamber 34 is larger than the height of the rotor 30.
[0073] The rotor storage chamber 34 has a storage chamber inner wall 35 that defines a space for storing the rotor 30. The storage chamber inner wall 35 restricts the horizontal rotation of the rotor 30. Specifically, when the rotor 30 rotates horizontally, the rotor 30 rotates while contacting the storage chamber inner wall 35. This restricts the rotation center of the rotor 30. In other words, the storage chamber inner wall 35 restricts the position in the XY direction of the central axis CX1, which is the rotation center of the rotor 30. This allows the rotor 30 to rotate horizontally around the central axis CX1 that extends through the through hole 31 in the up-down direction.
[0074] Furthermore, the rotor 30 rotates while swinging horizontally within the rotor storage chamber 34. Specifically, the center of rotation of the rotor 30 is not fixed, and the rotor storage chamber 34 is larger in outer diameter than the rotor 30 when viewed from the height direction (Z direction) of the component supply device 1. Therefore, when the rotor 30 rotates while contacting the storage chamber inner wall 35, the central axis CX1, which is the center of rotation of the rotor 30, swings horizontally. As a result, the rotor 30 rotates while swinging horizontally. In this way, the rotor 30 rotates horizontally while swinging, thereby allowing the multiple components to be more agitated as they pass through the through-holes 31.
[0075] The component alignment section 3 is provided with a second agitation air supply path 36 that supplies air to the rotor housing chamber 34. The second agitation air supply path 36 is connected to the agitation air supply tube 10 and forms part of the agitation air supply path 7.
[0076] The second agitation air supply path 36 supplies air into the rotor housing chamber 34. Specifically, the second agitation air supply path 36 is provided in the component alignment unit 3 so that air is supplied toward the plurality of blades 33 of the rotor 30. For example, the second agitation air supply path 36 is formed by piping.
[0077] In the component alignment unit 3, air supplied from the second agitation air supply path 36 collides with the blades 33, thereby pressing the blades 33. This causes the rotor 30 to rotate horizontally around the central axis CX1 as the center of rotation.
[0078] In addition, an agitating air introduction path 37 is provided between the rotor 30 and the agitating unit 4, which introduces air from the rotor storage chamber 34 to the component insertion port 41. The agitating air introduction path 37 is a flow path that introduces a portion of the air supplied into the rotor storage chamber 34 to the agitating chamber 40. The agitating air introduction path 37 is formed by the gap between the rotor 30 and the agitating unit 4. The flow path width of the agitating air introduction path 37 is smaller than the dimensions of the components.
[0079] When air is supplied from the second agitation air supply passage 36 to the rotor housing chamber 34 , part of the air passes through the agitation air introduction passage 37 and flows from the rotor housing chamber 34 to the agitation chamber 40 of the agitator 4 .
[0080] The component alignment section 3 is provided with a portion of a bypass flow path 70 that diverts a portion of the air in the rotor housing chamber 34 to the agitation section 4. Specifically, the component alignment section 3 is provided with a return flow path 71 and a portion of a return air storage section 72. The bypass flow path 70 will be described later.
[0081] <Stirring section> The mixing unit 4 is disposed above the component alignment unit 3, and mixes the components while feeding the components into the component alignment unit 3. Specifically, the mixing unit 4 has a mixing chamber 40 that mixes the components.
[0082] 5 and 7, the stirring chamber 40 is provided with a component insertion port 41 that is above the rotor 30 and opens toward the through-hole 31. The component insertion port 41 is provided on the bottom surface of the component alignment unit 3. When viewed from the height direction (Z direction) of the component supply device 1, the component insertion port 41 has, for example, a circular shape.
[0083] The stirring chamber 40 is formed by a through-hole that passes through the component alignment unit 3 in the vertical direction. Specifically, the stirring chamber 40 is formed by a tapered through-hole whose diameter decreases from the top surface to the bottom surface of the component alignment unit 3. More specifically, the stirring chamber 40 is formed by a through-hole in the shape of an inverted truncated cone.
[0084] The stirring chamber 40 has an inner wall 42. The inner wall 42 is inclined so that the dimensions (hole diameter) of the stirring chamber 40 become smaller toward the component insertion port 41. The inner wall 42 is inclined toward the through-hole 31 of the rotor 30. As a result, a plurality of components are guided by the inner wall 42 and inserted from the component insertion port 41 toward the through-hole 31 of the rotor 30.
[0085] A plurality of jetting ports 43 are provided on the inner wall 42 of the stirring chamber. The plurality of jetting ports 43 are holes from which air is jetted. The jetting ports 43 have a size smaller than the size of the components. The plurality of jetting ports 43 are provided in the bypass flow path 70. Specifically, the plurality of jetting ports 43 are provided in the return air supply path 73.
[0086] The bypass flow path 70 diverts a portion of the air supplied to the rotor housing chamber 34 of the component alignment unit 3 and supplies it to the stirring chamber 40 of the stirring unit 4. The bypass flow path 70 has a return flow path 71, a return air storage unit 72, and a return air supply path 73. In this embodiment, the return flow path 71 and a portion of the return air storage unit 72 are provided in the component alignment unit 3, and a portion of the return air storage unit 72 and the return air supply path 73 are provided in the stirring unit 4.
[0087] The return path 71 is a path through which the air supplied to the rotor housing chamber 34 returns. The return path 71 connects the rotor housing chamber 34 and the return air storage section 72. For example, the return path 71 is formed by piping. A portion of the air supplied from the second agitation air supply path 36 to the rotor housing chamber 34 flows through the return path 71 to the return air storage section 72.
[0088] The return air reservoir 72 stores the air that has flowed in from the return path 71. The air stored in the return air reservoir 72 flows into the return air supply path 73.
[0089] The return air supply path 73 is a flow path through which the air stored in the return air storage section 72 flows, and is in communication with the plurality of outlets 43. The air flowing through the return air supply path 73 is ejected from the plurality of outlets 43.
[0090] The stirring chamber 40 stirs the multiple components and feeds the multiple components from the component insertion port 41 into the through-hole 31. The stirring chamber 40 stirs the multiple components using air. Specifically, the stirring chamber 40 stirs the multiple components using air introduced from the stirring air introduction path 37 and air ejected from the multiple ejection ports 43. In the stirring chamber 40, the stirred multiple components fall under their own weight, are guided by the inner wall 42 of the stirring chamber, and are fed from the component insertion port 41 into the through-hole 31.
[0091] 8 is a schematic diagram showing an example of air flow in the component supplying device 1 according to the first embodiment of the present disclosure. As shown in FIG. 8, when air is supplied from the second agitation air supply path 36 to the rotor housing chamber 34, the air presses against the blades 33 of the rotor 30, causing the rotor 30 to rotate horizontally around the central axis CX1. In this manner, the rotor 30 rotates due to the force of the air.
[0092] A portion of the air supplied to the rotor housing chamber 34 passes through the agitating air inlet path 37 and flows from the rotor housing chamber 34 to the component insertion port 41. That is, a portion of the air passes through the agitating air inlet path 37 and flows from the rotor housing chamber 34 into the agitating chamber 40. This causes an air flow to rise within the agitating chamber 40. As a result, the multiple components in the agitating chamber 40 are agitated.
[0093] Another portion of the air supplied to the rotor housing chamber 34 flows from the rotor housing chamber 34 to the stirring chamber 40 through the bypass flow path 70. That is, another portion of the air flows into the stirring chamber 40 through the return flow path 71, the return air reservoir 72, and the return air supply path 73. Specifically, the air flowing through the bypass flow path 70 is ejected into the stirring chamber 40 from the multiple outlets 43. This generates a flow of air that rises within the stirring chamber 40 from the multiple outlets 43. As a result, the multiple parts in the stirring chamber 40 are agitated.
[0094] As described above, in this embodiment, the agitation chamber 40 agitates the multiple components by utilizing the air introduced from the agitation air introduction passage 37 and the air ejected from the multiple ejection ports 43 .
[0095] In this embodiment, when air is supplied from the second agitation air supply path 36 to the rotor housing chamber 34, the rotor 30 is lifted by the force of the air. As a result, a conveying air introduction path 38 is formed between the rotor 30 and the component conveying path 6.
[0096] The conveying air inlet path 38 guides air from the rotor storage chamber 34 to the component conveying path 6. The conveying air inlet path 38 is a flow path that guides a portion of the air supplied into the rotor storage chamber 34 to the component conveying path 6. The conveying air inlet path 38 is formed by the gap between the rotor 30 and the component conveying path 6. The flow path width of the conveying air inlet path 38 is smaller than the dimensions of the component.
[0097] When air is supplied from the second agitation air supply path 36 to the rotor housing chamber 34, part of the air passes through the conveying air introduction path 38 and flows from the rotor housing chamber 34 to the component conveying path 6. This makes it possible to use the force of the air supplied to the rotor housing chamber 34 to push out multiple components in the component conveying path 6. In other words, the force of the air used to rotate the rotor 30 can be used to convey the components.
[0098] <Cassette holder> The cassette holding unit 5 is disposed above the mixing unit 4 and holds the component storage cassette 12. The cassette holding unit 5 is provided with a component introduction port 50 through which the multiple components stored in the component storage cassette 12 are introduced.
[0099] The component introduction port 50 communicates with the stirring chamber 40 of the stirring unit 4. Therefore, the components are introduced into the component introduction port 50, and are then introduced into the stirring chamber 40.
[0100] <Parts conveying path> The component conveying path 6 conveys the multiple components that have passed through the through holes 31 of the rotor 30 in a line. The component conveying path 6 conveys the multiple components to the component supply position P1 of the main body 2.
[0101] In this embodiment, a component conveying opening 60 is provided in the component alignment section 3. The component conveying opening 60 is connected to a component conveying tube 9. The component conveying opening 60 and the component conveying tube 9 form a component conveying path 6.
[0102] The component transfer opening 60 is a hole that opens toward the through-hole 31 below the rotor 30. Specifically, the component transfer opening 60 is a through-hole that penetrates the bottom surface of the rotor storage chamber 34 and the bottom surface of the component alignment unit 3. The component transfer opening 60 is provided at a position facing the through-hole 31 of the rotor 30 in the vertical direction.
[0103] When viewed from the vertical direction (Z direction), the component transfer opening 60 is larger than the opening of the through hole 31 facing the component transfer opening 60, i.e., the opening of the second through hole 31b. Furthermore, the hole diameter of the component transfer opening 60 decreases toward the component transfer tube 9 in the vertical direction (Z direction).
[0104] In this embodiment, the rotor 30 rotates horizontally while swinging horizontally. Therefore, the through-hole 31 also swings horizontally. If the component transfer opening 60 is larger than the opening of the second through-hole 31b, multiple components discharged from the second through-hole 31b can smoothly pass through the component transfer opening 60 and be moved to the component transfer tube 9, even when the rotor 30 swings horizontally.
[0105] The component conveying tube 9 is connected to a component conveying path 61 in the main body, which will be described later.
[0106] 9 is a schematic diagram showing an example of the operation of the component supplying device 1 according to the first embodiment of the present disclosure. Fig. 9 shows how a plurality of components 80 are mixed by the component supplying device 1 and aligned in a line.
[0107] 9, multiple components 80 are introduced from the component storage cassette 12 into the stirring chamber 40 of the stirring unit 4 through the component inlet 50 of the cassette holder 5. In the stirring chamber 40, the multiple components 80 are stirred using air force, and are guided from the component feed port 41 into the through-holes 31 of the rotor 30. Specifically, the multiple components 80 are stirred in the stirring chamber 40 by air introduced from the stirring air inlet path 37 and air ejected from the multiple ejection ports 43 through the bypass flow path 70.
[0108] The rotor 30 rotates horizontally while swinging horizontally about the central axis CX1 due to the force of the air supplied from the second agitation air supply path 36. The multiple components 80 fall through the through-holes 31 while coming into contact with the rotor inner walls 31c of the rotor 30. At this time, because the rotor inner walls 31c are rotating and swinging together with the rotor 30, when the multiple components 80 come into contact with the rotor inner walls 31c in the first through-holes 31a, the multiple components 80 are easily dispersed. That is, the multiple components 80 are also easily agitated in the first through-holes 31a of the rotor 30.
[0109] After passing through the first through-hole 31a, the multiple components 80 are aligned in a line at the second through-hole 31b. The multiple components 80 are discharged from the second through-hole 31b to the component transport opening 60 in a lined state. As a result, the multiple components 80 are sent to the component transport path 6 and transported to the component supply position P1.
[0110] Furthermore, when the plurality of components 80 are sent to the component conveying path 6, the plurality of components 80 within the component conveying path 6 are pushed out by air introduced from the conveying air introduction path 38.
[0111] Next, the wheel 90, wheel holding portion 91, wheel driving portion 92, and negative pressure introduction path 93 will be described with reference to Figures 10 to 12. Figure 10 is a schematic plan view of the periphery of component supply position P1 of the main body 2. Figure 11 is a schematic cross-sectional view taken along line DD in Figure 3. Figure 12 is a schematic cross-sectional view taken along line EE in Figure 10.
[0112] <Wheels> As shown in FIGS. 10 to 12, the wheel 90 rotates around a central axis CX2 extending horizontally. In this embodiment, the central axis CX2 extends in the X direction. The wheel 90 has a side surface 90a extending perpendicular to the central axis CX2 and an outer peripheral surface 90b provided on the outer periphery of the side surface 90a. The wheel 90 has, for example, a disk shape.
[0113] The outer peripheral surface 90b is a surface that defines the outer periphery of the wheel 90 and extends parallel to the central axis CX2. A plurality of component storage recesses 90c that store the components 80 are provided on the outer peripheral surface 90b.
[0114] The component storage recesses 90c are arranged radially around the central axis CX2 when viewed horizontally. Specifically, the component storage recesses 90c are arranged at equal intervals in the rotation direction of the wheel 90.
[0115] The component storage recess 90c is formed by removing a portion of the side surface 90a and the outer peripheral surface 90b of the wheel 90. Specifically, the component storage recess 90c is recessed in a direction from the outer peripheral surface 90b toward the central axis CX2 and opens toward the side surface 90a. That is, openings of the component storage recess 90c are formed in both the side surface 90a and the outer peripheral surface 90b.
[0116] In the component storage recess 90c, an opening on the side surface 90a of the wheel is connected to the internal component conveying path 61 at a component separation position P2. The component separation position P2 is a position where one component 80 is sequentially separated from a plurality of components 80. The component separation position P2 is located before the component supply position P1 in the rotation direction of the wheel 90. Specifically, while the component supply position P1 is located at the top of the wheel 90, the component separation position P2 is located below the component supply position P1 and above the central axis CX2.
[0117] At the component separation position P2, one component 80 is separated from the multiple components 80 in the internal component transport path 61 and transported to the component storage recess 90c. After the component 80 is transported to the component storage recess 90c at the component separation position P2, the wheel 90 rotates while holding the component 80 in the component storage recess 90c, and the component 80 moves to the component supply position P1.
[0118] The component storage recess 90c is formed to a size that allows it to store one component 80. In this embodiment, the component storage recess 90c has a longitudinal direction that is parallel to the direction in which the central axis CX2 of the wheel 90 extends and a lateral direction that is aligned with the rotation direction of the wheel 90. For example, the component storage recess 90c has a rectangular shape when viewed from the outer circumferential surface 90b side.
[0119] The wheel 90 is held by a wheel holding unit 91 and rotated by a wheel driving unit 92 .
[0120] A part of the negative pressure introduction passage 93 (the second negative pressure introduction passage 93b and the third negative pressure introduction passage 93c) is provided in the wheel 90. Furthermore, inside the wheel 90, a magnet 94 is arranged near the component storage recess 90c.
[0121] <Wheel holding part> The wheel holding portion 91 rotatably houses and holds the wheel 90. The wheel holding portion 91 rotatably covers the wheel 90. The wheel holding portion 91 is also provided with a component supply opening 2a that exposes a portion of the outer peripheral surface 90b of the wheel 90.
[0122] The wheel holding portion 91 has a wheel storage block 91a, a first side block 91b, and a second side block 91c.
[0123] The wheel storage block 91a is a block provided with a storage hole in which the wheel 90 is rotatably disposed. The inner wall of the wheel storage block 91a contacts the outer peripheral surface 90b of the wheel 90. That is, the wheel 90 rotates within the storage hole of the wheel storage block 91a while the outer peripheral surface 90b of the wheel 90 contacts the inner wall of the wheel storage block 91a.
[0124] An air suction passage 26 is provided in the wheel storage block 91a.
[0125] The first side block 91b and the second side block 91c are blocks that are arranged on both side surfaces of the wheel storage block 91a.
[0126] The first side block 91b is provided with a mounting hole to which the wheel drive unit 92 is attached. Also, the first side block 91b is provided with a part of the negative pressure introduction path 93 (first negative pressure introduction path 93a).
[0127] The second side block 91c is provided with an internal component conveying path 61. The internal component conveying path 61 constitutes part of the component conveying path 6. The internal component conveying path 61 is connected to the component conveying tube 9. The end of the internal component conveying path 61 is located at the component separation position P2.
[0128] A plurality of components 80 aligned in a row are conveyed from the component conveying tube 9 to the internal component conveying path 61. At the component separation position P2, the internal component conveying path 61 separates one component 80 from the aligned components 80 and conveys it to the component storage recess 90c.
[0129] The cross section of the internal component conveying path 61 has a rectangular shape. The width of the internal component conveying path 61 is designed to allow one component to pass through.
[0130] A component detection sensor 14 is disposed on the internal component conveying path 61. The component detection sensor 14 detects whether or not a component 80 is present on the internal component conveying path 61. The component detection sensor 14 is, for example, an optical sensor, a magnetic sensor, or a capacitance sensor.
[0131] <Wheel drive unit> The wheel driving unit 92 rotates the wheel 90. The wheel driving unit 92 moves the component 80 placed in the component storage recess 90c to the component supply opening 2a. That is, by rotating the wheel 90, the wheel driving unit 92 moves the component 80 transported to the component storage recess 90c to the component supply position P1.
[0132] The wheel driver 92 rotates the wheel 90 to move the component storage recess 90c to the component separation position P2. This connects the component storage recess 90c to the internal component transfer path 61, and one component 80 is transferred from the internal component transfer path 61 to the component storage recess 90c. In this embodiment, the internal component transfer path 61 uses air to transfer the component 80 to the component storage recess 90c.
[0133] The wheel driving unit 92 is an actuator capable of controlling the amount of rotation of the wheel 90. The wheel driving unit 92 is controlled by the wheel control unit 29 of the control unit 20. For example, the wheel driving unit 92 is a motor.
[0134] <Negative pressure introduction path> The negative pressure introduction path 93 holds the components 80 placed in the component storage recess 90c by applying negative pressure. By applying negative pressure to the component storage recess 90c, the negative pressure introduction path 93 can maintain the state in which the components 80 are placed in the component storage recess 90c. Furthermore, at the component separation position P2, the negative pressure introduction path 93 sucks the components 80 from the internal component transfer path 61 and transfers them to the component storage recess 90c. In this embodiment, the negative pressure introduction path 93 corresponds to a component holder.
[0135] The negative pressure introduction passage 93 has a first negative pressure introduction passage 93a, a second negative pressure introduction passage 93b, and a third negative pressure introduction passage 93c.
[0136] The first negative pressure introduction path 93a is provided inside the first side block 91b and is connected to the air suction path .
[0137] The second negative pressure introduction passage 93b is provided inside the first side block 91b and is connected to the first negative pressure introduction passage 93a. The second negative pressure introduction passage 93b is provided in an arch shape along the rotation direction of the wheel 90. The second negative pressure introduction passage 93b is provided between the component separation position P2 and the component supply position P1. Specifically, the starting end of the second negative pressure introduction passage 93b is located at the end of the first negative pressure introduction passage 93a, and the end of the second negative pressure introduction passage 93b is located just before the component supply position P1.
[0138] The third negative pressure introduction passage 93c is provided inside the wheel 90 and extends from the concave surface of the component-storing recess 90c in a direction toward the central axis CX2.
[0139] As the wheel 90 rotates, the third negative pressure introduction path 93c is connected to the second negative pressure introduction path 93b while the third negative pressure introduction path 93c is moving from the component separation position P2 to the component supply position P1. This allows the component storage recess 90c to be under negative pressure while the component 80 placed in the component storage recess 90c is being moved from the component separation position P2 to the component supply position P1. As a result, the component 80 placed in the component storage recess 90c can be maintained.
[0140] Since the end of the second negative pressure introduction path 93b is located just before the component supply position P1, the connection between the third negative pressure introduction path 93c and the second negative pressure introduction path 93b is released just before the component supply position P1. As a result, the component storage recess 90c is not under negative pressure at the component supply position P1, and the component 80 can be easily picked up from the component storage recess 90c.
[0141] In this embodiment, a magnet 94 is disposed inside the wheel 90. The magnet 94 holds the component 80 disposed in the component storage recess 90c by magnetic force. In this embodiment, the magnet 94 corresponds to a component holder.
[0142] FIG. 13 is a schematic diagram showing an example of the operation of transporting components 80 to the component storage recess 90c. As shown in FIG. 13, multiple components 80 are transported in a line in the internal component transport path 61 along the longitudinal direction of the components 80 (first longitudinal direction). At the component separation position P2, the internal component transport path 61 transports the components 80 to the component storage recess 90c with the longitudinal direction (first longitudinal direction) of the components 80 aligned with the longitudinal direction (second longitudinal direction) of the component storage recess 90c. In this way, at the component separation position P2, the longitudinal direction (first longitudinal direction) of the components 80 is aligned with the longitudinal direction (second longitudinal direction) of the component storage recess 90c before the components 80 are transported to the component storage recess 90c.
[0143] When the component 80 is transported to the component storage recess 90c, a negative pressure is created in the component storage recess 90c by sucking air through the negative pressure introduction path 93. This allows the component 80 to be moved from the internal component transport path 61 to the component storage recess 90c.
[0144] As described above, in this embodiment, the main body internal component conveying path 61 conveys the components 80 to the component storage recess 90c by using air.
[0145] Furthermore, when the component 80 is transported to the component storage recess 90c, the component 80 may be magnetically attracted by the magnet 94, thereby moving the component 80 from the internal component transport path 61 to the component storage recess 90c.
[0146] FIG. 14 is a flowchart showing an example of the processing operation of the component supply device 1 according to the first embodiment of the present disclosure.
[0147] 14, in step S1, the component detection sensor 14 detects whether or not a component 80 is present on the component conveying path 6. In this embodiment, the component detection sensor 14 is disposed on the internal component conveying path 61 provided in the wheel holding portion 91 of the main body 2. Therefore, the component detection sensor 14 detects whether or not a component 80 is present on the internal component conveying path 61. The detection result of the component detection sensor 14 is transmitted to the control unit 20.
[0148] If the component detection sensor 14 detects that there is a component on the component conveying path 6, the process repeats step S1. On the other hand, if the component detection sensor 14 does not detect that there is a component on the component conveying path 6, the process proceeds to step S2.
[0149] In step S2, the agitation processing unit 28 of the control unit 20 controls the agitation air control valve 24. Specifically, the agitation processing unit 28 continuously opens and closes the agitation air control valve 24. This causes air to be intermittently supplied to the component alignment unit 3 through the agitation air supply path 7. As a result, the multiple components 80 are agitated in the component alignment unit 3 and the agitation unit 4.
[0150] In step S3, the component detection sensor 14 detects whether or not a component 80 is present on the component conveying path 6. In step S3, if the component detection sensor 14 detects that a component is present on the component conveying path 6, the process returns to step S1. On the other hand, if the component detection sensor 14 does not detect that a component 80 is present on the component conveying path 6, the process proceeds to step S4.
[0151] In step S4, the control unit 20 controls the notification lamp 13. Specifically, the control unit 20 turns on the notification lamp 13. This notifies the user that the component 80 in the component storage cassette 12 has run out.
[0152] Fig. 15 is a schematic diagram illustrating an example of the operation of the component mounting device 100 according to the first embodiment of the present disclosure. Fig. 15 illustrates an example in which the rotation amount of the wheel 90 is corrected in a plurality of component supply devices 1 so that the component storage recesses 90c are arranged along the alignment line L1. For ease of explanation, Fig. 15 illustrates the configuration of the vicinity of the component storage recesses 90c exposed from the component supply opening 2a in the component supply device 1.
[0153] For example, when there is variation in the placement positions of the component supplying devices 1 or variation due to differences between machines, the positions of the component storage recesses 90c exposed from the component supplying opening 2a will vary. Therefore, the control unit 20 corrects the amount of rotation of the wheel 90 based on the variation in the positions of the component storage recesses 90c among the component supplying devices 1. Specifically, the control unit 20 controls the amount of rotation of the wheel 90 in the component supplying devices 1 so that the component storage recesses 90c exposed from the component supplying opening 2a are positioned on the alignment line L1.
[0154] For example, the control unit 20 acquires information on the variation in the positions of the component storage recesses 90c among the component supply devices 1. For example, the information on the variation is obtained by capturing images of the component storage recesses 90c among the component supply devices 1 using a camera, and calculating the amount of deviation in the Y direction from the alignment line L1 based on the captured images.
[0155] Based on the amount of deviation, the control unit 20 calculates the amount of rotation correction for the wheel 90. Specifically, the control unit 20 calculates the amount of rotation correction so as to eliminate deviation in the Y direction.
[0156] The control unit 20 corrects the amount of rotation of the wheel 90 based on the calculated rotation correction amount. Specifically, the control unit 20 corrects the amount of rotation of the wheel 90 by controlling the wheel driving unit 92.
[0157] In this way, by correcting the amount of rotation of the wheel 90, it is possible to align the component-storing recesses 90c along the alignment line L1.
[0158] 16 is a schematic diagram illustrating another example of the operation of the component mounting device 100 according to the first embodiment of the present disclosure. FIG. 16 illustrates an example of correcting the rotation amount of the wheel 90 based on variations in the pickup units 103.
[0159] When viewed from the top-bottom direction, the positions of the multiple pickup units 103 may vary in a direction (Y direction) perpendicular to the direction in which the multiple pickup units 103 are arranged (X direction). For this reason, the control unit 20 corrects the amount of rotation of the wheel 90 based on the variation in the positions of the multiple pickup units 103. Specifically, when picking up a component 80, the control unit 20 corrects the amount of rotation of the wheel 90 so that the positions of the multiple pickup units 103 and the positions of the multiple component storage recesses 90c overlap in the top-bottom direction.
[0160] For example, the control unit 20 acquires information on the variation in the positions of the plurality of pickup units 103. For example, the variation information is obtained by capturing images of the plurality of pickup units 103 with a camera and calculating the amount of deviation in the Y direction based on the captured images.
[0161] The control unit 20 calculates the rotation correction amount for the wheel 90 based on the amount of deviation. Specifically, the control unit 20 calculates the rotation correction amount so that the deviation in the Y direction is eliminated. That is, the control unit 20 calculates the rotation correction amount for the wheel 90 so that, when picking up components 80, the positions of the multiple pickup units 103 and the positions of the multiple component storage recesses 90c overlap in the vertical direction.
[0162] The control unit 20 corrects the amount of rotation of the wheel 90 based on the calculated rotation correction amount. Specifically, the control unit 20 corrects the amount of rotation of the wheel 90 by controlling the wheel driving unit 92.
[0163] In this way, by correcting the amount of rotation of the wheel 90, the positions of the plurality of component-storing recesses 90c can be adjusted in accordance with variations in the positions of the plurality of pickup units 103.
[0164] The component supplying device 1 and the component mounting device 100 according to the first embodiment of the present disclosure can provide the following effects.
[0165] The component supply device 1 includes a wheel 90, a wheel holding unit 91, a component conveying path 6, and a wheel driving unit 92. The wheel 90 has an outer circumferential surface 90b provided with a plurality of component storage recesses 90c for storing components 80, and rotates about a horizontally extending central axis CX2. The wheel holding unit 91 rotatably holds the wheel 90. The wheel holding unit 91 is provided with a component supply opening 2a that exposes a portion of the outer circumferential surface 90b of the wheel 90. The component conveying path 6 aligns the plurality of components 80 in a line and conveys one component 80 to one component storage recess 90c within the wheel holding unit 91. The wheel driving unit 92 rotates the wheel 90, moving the component 80 conveyed to the component storage recess 90c to the component supply opening 2a.
[0166] With this configuration, components can be sequentially picked up from the aligned components and transported to the component supply position. Specifically, the components 80 are aligned on the component transport path 6, and the components 80 are transported one by one to the component storage recesses 90c of the wheel 90. After the components 80 are transported to the component storage recesses 90c, the wheel 90 rotates, causing the components 80 to move to the component supply opening 2a provided at the component supply position P1. In this way, the component supply device 1 can align the components 80, sequentially pick up the components 80 from the aligned components, and transport them to the component supply position P1.
[0167] The component conveying path 6 conveys the component 80 to the component storage recess 90c by using air. With this configuration, the component 80 can be easily moved to and stored in the component storage recess 90c.
[0168] The component supply device 1 further includes component holders 93 and 94 that hold the component 80 in the component storage recess 90c. With this configuration, when the wheel 90 rotates to move the component 80 placed in the component storage recess 90c to the component supply opening 2a, the component 80 can be held in the component storage recess 90c.
[0169] The component holder 93 has negative pressure introduction paths 93a-93c that apply negative pressure to hold the components 80 placed in the component storage recess 90c. With this configuration, the components 80 can be held in the component storage recess 90c by applying negative pressure.
[0170] The component holder 94 has a magnet 94 that magnetically holds the component 80 placed in the component storage recess 90c. With this configuration, the component 80 can be held in the component storage recess 90c by magnetic force.
