[0011] Hereinafter, the embodiments will be specifically described with reference to the drawings.

[0012] The embodiments described below are all comprehensive or specific examples. The numerical values, shapes, components, component placement and connection configurations, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components not described in independent claims are described as optional components.

[0013] Furthermore, each figure is a schematic diagram and is not necessarily an exact illustration. Therefore, for example, the scales of the figures do not necessarily match. Furthermore, in each figure, substantially the same components are given the same reference numerals, and redundant explanations are omitted or simplified.

[0014] In this specification and drawings, the X-axis, Y-axis, and Z-axis represent the three axes of a three-dimensional Cartesian coordinate system. In each embodiment, the X-axis direction represents the component transport direction, and the Z-axis direction represents the up-down direction of the component supply device. A plan view refers to a view from the Z-axis direction, and a cross-sectional view refers to a view of a cross section defined by the Y-axis and Z-axis from the X-axis direction.

[0015] Furthermore, in this specification, terms indicating the relationship between elements, such as perpendicular and parallel, terms indicating the shape of elements, such as circular, as well as numerical values ​​and numerical ranges, are not expressions that express only the strict meaning, but are expressions that also include a substantially equivalent range, for example, a difference of a few percent (e.g., less than 10%).

[0016] (Embodiment) Hereinafter, a component supply device according to the present embodiment will be described with reference to FIGS.

[0017] [1. Components supply device configuration] First, the configuration of a supply unit having a component supply device according to this embodiment will be described with reference to FIG. 1. FIG. 1 is a diagram schematically illustrating a supply unit 80 according to this embodiment. The supply unit 80 is a device for supplying components (e.g., electronic components) used in a component mounting device (e.g., component mounting device 100 shown in FIG. 10) described below. Note that FIG. 1 also illustrates a mounting head 107 that holds and removes components from feeder 20 when supply unit 80 is attached to the component mounting device. Holding includes at least one of suction and gripping. Also, FIG. 1 illustrates a state in which cover 11 of case 10 is open.

[0018] 1, the supply unit 80 includes a case 10, a feeder 20, and a carriage 70. The supply unit 80 is movable and is removably attached to the component mounting apparatus.

[0019] The case 10 is a hollow box that stores components in a loose state. The case 10 stores, for example, bulk components. The case 10 is detachably attached to the feeder 20 and supplies the stored components to the feeder 20. For example, the case 10 supplies the stored components to the feeder 20 by being shaken by vibration or the like while attached to the feeder 20. The case 10 is an example of a component storage unit. The components are, for example, electronic components such as resistors and capacitors, but are not limited thereto and may be any object that can be mounted on an object such as a circuit board. At least a portion of the component may be metal, or may be electrically charged or magnetic. The metal portion or the electrically charged or magnetic portion may be exposed, for example. The metal portion may be, for example, a metal layer (plated layer).

[0020] Case 10 has cover 11. Cover 11 is provided at an opening for supplying components from inside case 10 to feeder 20. Cover 11 covers the opening when case 10 is not attached to feeder 20. Cover 11 is opened when case 10 is attached to feeder 20. For example, when case 10 is attached to attachment portion 32 of feeder 20, cover 11 is pushed toward the negative X-axis side by a rod (not shown) provided at attachment portion 32, causing cover 11 to rotate around the Y-axis direction as a rotation axis.

[0021] Feeder 20 supplies components stored in case 10 in a bulk state to a removal position where the components are removed by mounting head 107. In this embodiment, feeder 20 is configured to transport components by air rather than vibration.

[0022] The feeder 20 is detachably attached to the carriage 70, which moves the feeder 20 to a predetermined position in the component mounting device. Note that the carriage 70 is not an essential component.

[0023] Here, feeder 20 will be further described with reference to Figures 2 to 6B. Figure 2 is a perspective view that schematically shows a part of feeder 20 according to the present embodiment.

[0024] As shown in FIGS. 1 and 2, the feeder 20 includes a component supply device 30 and a main body 60.

[0025] The component supply device 30 has the case 10 removably attached thereto, and transports the components supplied from the case 10.

[0026] The component supply device 30 has a conveying unit 40 and a supply unit 50. The component supply device 30 also has a mounting unit 32 to which the case 10 is mounted, and a tube 36 used for vacuum suction to fix the component.

[0027] The conveying unit 40 is a conveying mechanism for aligning a plurality of components supplied from the case 10 to the component supply position 42 and conveying them to the supplying unit 50. The conveying unit 40 has, for example, a second sensor 41 that detects the amount of components stored in the conveying unit 40. It can also be said that the second sensor 41 detects the accumulation state of components (e.g., the amount of components) in the conveying unit 40. The second sensor 41 may, for example, detect the accumulation state of components in a first conveying section (e.g., the first conveying section 40a1 shown in FIG. 4A) described below. The second sensor 41 may, for example, detect the presence or absence of components at a predetermined position in the conveying unit 40. The second sensor 41 is not particularly limited as long as it is a sensor that can detect components. The second sensor 41 may be a sensor that detects components using light. The second sensor 41 is an example of a second detecting unit.

[0028] Note that "alignment" means aligning the orientation of multiple components and lining them up in a line. When the components are rectangular parallelepipeds, alignment means, for example, orienting the long sides of the components in a first direction (positive X-axis direction) from the component supply position 42 toward the supply unit 50, and lining up the components facing the first direction in a line. Note that "lining up" does not necessarily mean a perfect line, but may mean a substantially single line, and may be, for example, a zigzag pattern. Note that, hereinafter, a direction (e.g., X-axis direction) and an orientation (e.g., positive X-axis direction) will be simply referred to as a direction (e.g., first direction).

[0029] Supply unit 50 is a conveying mechanism connected at one end to transport unit 40, for supplying a plurality of components transported from transport unit 40 to a removal position where the components are removed by mounting head 107. Supply unit 50 has a first sensor 51 that detects the amount of components stored in supply unit 50. First sensor 51 detects, for example, the presence or absence of components at a predetermined position in supply unit 50. First sensor 51 is provided, for example, near supply unit inlet 52, which is the connection position between transport unit 40 and supply unit 50, and detects components that have passed through supply unit inlet 52. There are no particular limitations on first sensor 51, as long as it is a sensor that can detect components. First sensor 51 may also be a sensor that detects components using light.

[0030] The mounting portion 32 is a portion to which the case 10 is attached and detached, and serves to fix the case 10 and open and close the cover 11 of the case 10 .

[0031] Tube 36 forms a vacuum path for fixing the component transported to the removal position by vacuum suction. Tube 36 communicates with a suction hole (suction hole 55a shown in FIG. 6B) for suctioning the component provided in supply unit 50. This suction hole is provided at the removal position.

[0032] The component supply device 30 is detachably attached to the main body 60. The main body 60 is a housing, for example, a box, that houses the first air supply unit 62 (first supply unit 62), the second air supply unit 63 (first supply unit 63), the third sensor 64, etc. The main body 60 may also house the control unit 61.

[0033] The first air supply unit 62 communicates with a plurality of air outlets that open to the transfer unit 40, and supplies air that is ejected from the plurality of air outlets.

[0034] The second air supply unit 63 communicates with the plurality of air outlet holes that open to the supply unit 50, and supplies air that is ejected from the plurality of air outlet holes.

[0035] The first air supply unit 62 and the second air supply unit 63 supply compressed air to a level sufficient to float and transport components. The pressure of the compressed air is controlled by a regulator or the like. A first air passage (e.g., the broken-line path connected to the first air supply unit 62 in FIG. 2) is formed between the first air supply unit 62 and the multiple air outlets of the transport unit 40 by a tube or the like, and a valve (e.g., an electromagnetic valve) is provided on the first air passage to switch on / off the supply of air. A second air passage (e.g., the broken-line path connected to the second air supply unit 63 in FIG. 2) is formed between the second air supply unit 63 and the multiple air outlets of the supply unit 50 by a tube or the like, and a valve (e.g., an electromagnetic valve) is provided on the second air passage to switch on / off the supply of air. The gas supplied by the first air supply unit 62 and the second air supply unit 63 is not limited to air and may be other gases.

[0036] The third sensor 64 detects whether a component is present at the removal position by measuring the air flow rate or vacuum level in a vacuum path connected to a suction hole provided in the supply unit 50 for suctioning components. The third sensor 64 detects that a component is present at the removal position when the air flow rate is below a predetermined value or the vacuum level is above a predetermined value. The mounting head 107 suctions and holds the component at the removal position based on the detection result of the third sensor 64. The vacuum path is an example of an air path. The third sensor 64 is an example of a third detection unit.

[0037] The control unit 61 is a control device that controls the transportation of components in the component supply device 30. The control unit 61 controls the transportation of components in the transport unit 40 and the transportation of components in the supply unit 50 independently of each other. For example, the control unit 61 controls the air to be ejected from the multiple air ejection holes of the transport unit 40 and the air to be ejected from the multiple air ejection holes of the supply unit 50 independently of each other via an air supply mechanism. Controlling the air includes controlling at least one of turning the air on and off, the air pressure, the air ejection direction, the air flow rate, etc.

[0038] It can also be said that the control unit 61 controls the air supply mechanism. The air supply mechanism is configured to include, for example, at least one of a first air supply unit 62, a second air supply unit 63, a regulator, a valve, an air path, and air outlets. The air supply mechanism is a mechanism for ejecting air for transporting components from, for example, a plurality of air outlets 43b opening on a support surface 43a (an example of a first support surface) on which components are supported in the transport unit 40, and a plurality of air outlets 53b opening on a support surface 53a (an example of a second support surface) on which components are supported in the supply unit 50.

[0039] The control unit 61 generates a thrust only in the first direction (forward, in the positive direction of the X-axis) by levitating and transporting the component. The control unit 61 may control the first air supply unit 62 and the second air supply unit 63, etc., to supply pulsed air by repeatedly turning on and off the air blowing at predetermined intervals. In other words, the component may be transported while moving up and down in the Z-axis direction. Note that the air blowing conditions for levitating and transporting are not limited to those described above.

[0040] Although the example in which the control unit 61 is provided in the main body unit 60 has been described, the present invention is not limited to this. For example, the control unit 61 may be provided in the component supply device 30.

[0041] The main body 60 may also house an air suction device that communicates with the suction holes and the tubes 36 and that fixes the component in the removal position by sucking air through the suction holes.

[0042] FIG. 3 is a perspective view showing a component supplying device 30 according to this embodiment. FIG. 4A is a plan view showing the component supplying device 30 according to this embodiment. Specifically, (a) of FIG. 4A shows a plan view of the component supplying device 30 according to this embodiment, (b) of FIG. 4A shows an enlarged view of the dashed-line area in the main body 40a shown in (a) of FIG. 4A, and (c) of FIG. 4A shows an enlarged view of the dashed-line area in the main body 50a shown in (a) of FIG. 4A. FIG. 4B is a plan view showing the component conveying direction in the component supplying device 30 according to this embodiment. FIG. 4B shows the component conveying directions d1 to d4 superimposed on the plan view shown in (a) of FIG. 4, with some reference numerals and the like removed. In FIG. 4B, the component conveying directions d1 to d4 are indicated by arrows with dotted hatching inside.

[0043] 5A is a cross-sectional view showing the Va-Va cross section shown in FIG. 4A(a). FIG. 5B is a cross-sectional view showing the Vb-Vb cross section shown in FIG. 4A(a). In FIGS. 5A and 5B, a rectangular part P is shown as an example of a part. In addition, in FIGS. 5A and 5B, symbols indicating the conveyance direction of the part P are shown. An x symbol in a circle indicates that the part P is being conveyed from the front to the back (from the positive side of the X axis to the negative side of the X axis), and a dot symbol in a circle indicates that the part P is being conveyed from the back to the front (from the negative side of the X axis to the positive side of the X axis).

[0044] 3 and 4A, the first sensor 51 and the second sensor 41 are not shown. In this embodiment, the propulsive force of the components in the component supply device 30 is entirely air. In other words, in this embodiment, vibration is not used to generate the propulsive force of the components in the component supply device 30.

[0045] 3, the transport unit 40 of the component supply device 30 has a main body 40a and a lid 40b. The lid 40b covers the main body 40a and is fixed to the main body 40a by fastening members 38 such as screws. The lid 40b has a through-hole 40b1 formed therein, through which the component from the case 10 passes. The component passes through the through-hole 40b1 and is supplied to the component supply position 42.

[0046] A rubber sheet member may be provided on the surface of the lid portion 40b on the negative side of the Z axis. When the lid portion 40b is fixed to the main body portion 40a, the sheet member may be provided within the component supply position 42 in a plan view, or may be provided at the boundary between the component supply position 42 and the component alignment portion 43 and the first inclined surface 44. When the lid portion 40b is fixed to the main body portion 40a, the sheet member is provided at a predetermined distance from the component supply position 42. For example, if the component is a rectangular parallelepiped, the predetermined distance is greater than the length of the shortest side of the component and less than the length of the longest side of the component. The sheet member contacts only upright components (components whose long sides are vertical) and functions to lay the components in a horizontal position. This prevents upright components from being transported to the component alignment portion 43 or the first inclined surface 44.

[0047] 3 and 4A, the main body 40a includes a second sensor 41 (see FIG. 2), a component supply position 42, a component alignment section 43, a first inclined surface 44, a second inclined surface 45, a cover 46, a swiveling section 47, a return conveyance section 48, side walls 49a and 49c, and a partition wall 49b. The air outlets of the conveyance section 40 are formed in the component supply position 42, the component alignment section 43, the first inclined surface 44, the second inclined surface 45, the swiveling section 47, and the return conveyance section 48.

[0048] The component supply position 42 is a portion (area) where components are supplied from the case 10. The component supply position 42 also contains components that have not been aligned in the component alignment section 43 but have returned via the return conveying section 48, and these components are conveyed in the conveying direction d4 shown in FIG. 4B. The component supply position 42 is formed with a plurality of air ejection holes (not shown) for supplying the components supplied from the case 10 and the components returned via the return conveying section 48 to the component alignment section 43. The component supply position 42 is a flat surface, but may have at least a portion that is inclined, for example.

[0049] The component supply position 42 is connected to both the component alignment section 43 and the first inclined surface 44. That is, a component at the component supply position 42 is supplied to either the component alignment section 43 or the first inclined surface 44 by air from a plurality of air outlets (not shown) formed at the component supply position 42.

[0050] The component alignment unit 43 aligns the components and transports them to the supply unit 50. The component alignment unit 43 aligns the components and transports them in a transport direction d1 shown in Fig. 4B. The component alignment unit 43 is provided to extend in a first direction.

[0051] As shown in (b) of Figure 4A, multiple air outlets 43b are formed on the support surface 43a of the component alignment unit 43. The component alignment unit 43 sequentially transports multiple components using air ejected from the multiple air outlets 43b. The component alignment unit 43 can simultaneously transport multiple components using the multiple air outlets 43b. Note that in (b) of Figure 4A, a portion of the air passage that connects the first air supply unit 62 and the air outlet 43b is shown by a dashed line in the air outlet 43b on the positive side of the X axis.

[0052] As shown in FIG. 5A, the component alignment section 43 is a concave groove extending in the first direction. The support surface 43a is formed by the bottom surface of the groove. The support surface 43a is located on the negative side of the Z axis from the first inclined surface 44. The support surface 43a is provided with a plurality of air outlets 43b, which are openings for floating and transporting components in the first direction. The plurality of air outlets 44b formed in the support surface 43a are configured to be able to eject air upward in the first direction. In other words, the plurality of air outlets 43b formed in the support surface eject air diagonally upward toward the first direction when viewed from the Y-axis direction. Furthermore, the plurality of air outlets 43b formed in the support surface 43a eject air perpendicular to the support surface 43a when viewed from the X-axis direction.

[0053] When component P is a rectangular parallelepiped, the width of component alignment section 43 in the Y-axis direction is greater than the length of the shortest side of component P and less than the length of the longest side of component P, but is not limited to this. Furthermore, when component P is a rectangular parallelepiped, the width of component alignment section 43 in the Y-axis direction may be less than twice the length of the shortest side of component P. Furthermore, the width of component alignment section 43 in the Y-axis direction may be determined taking into account the dimensional tolerance of component P.

[0054] In addition, the component alignment portion 43 is not limited to being a groove, and may be, for example, a flat surface connected to the lower end (the end on the positive side of the Y axis) of the first inclined surface 44, or may be an inclined surface inclined in the opposite direction to the first inclined surface 44.

[0055] The first inclined surface 44 is provided along the component alignment section 43 and is inclined downward toward the component alignment section 43. It can also be said that the first inclined surface 44 is provided adjacent to the component alignment section 43. The first inclined surface 44 is provided to move components supplied from the component supply position 42 to the first inclined surface 44 toward the component alignment section 43. The first inclined surface 44 is, for example, a flat inclined surface extending in the first direction.

[0056] The first inclined surface 44 is formed with a plurality of air ejection holes 44b, which are openings for floating and transporting components P on the first inclined surface 44 to the component alignment unit 43. The plurality of air ejection holes 44b formed in the first inclined surface 44 are capable of ejecting air in a first direction upward. When viewed from the X-axis direction, the plurality of air ejection holes 44b formed in the first inclined surface 44 eject air in a direction perpendicular to the first inclined surface 44. As shown in (b) of FIG. 4A, the first inclined surface 44 is formed with a plurality of air ejection holes 44b. Note that in (b) of FIG. 4A, a portion of the air passage for connecting the first air supply unit 62 and the air ejection holes 44b is shown by a dashed line in the air ejection hole 44b on the positive side of the X-axis.

[0057] The inclination angle of first inclined surface 44 is not particularly limited, but may be, for example, an angle at which components on first inclined surface 44 do not move (e.g., do not slip or rotate) to component alignment section 43 when air is not being ejected from multiple air ejection holes 44b of first inclined surface 44. This prevents friction from occurring between first inclined surface 44 and components P, i.e., blackening of the components, when components on first inclined surface 44 move to component alignment section 43 when air is not being ejected from multiple air ejection holes 44b of first inclined surface 44.

[0058] The inclination angle of first inclined surface 44 may be, for example, an angle at which components P on first inclined surface 44 move toward component alignment unit 43 while air is being ejected from multiple air ejection holes 44b of first inclined surface 44. The inclination angle of first inclined surface 44 may be, for example, 10 degrees or less, or 5 degrees or less. Note that the inclination angle is the angle at which the direction of support surface 43a of component alignment unit 43 (Y-axis direction) intersects with an extension line of first inclined surface 44 in FIG. 5A , and is an angle of 90 degrees or less.

[0059] Furthermore, since the air on the first inclined surface 44 is pulsed air, the components P on the first inclined surface 44 are more susceptible to the inclination of the first inclined surface 44 and can be more easily moved to the component alignment section 43.

[0060] 4A again, the second inclined surface 45 is provided along the component alignment section 43 on the downstream side (positive side of the X-axis) of the first inclined surface 44 in the first direction, and prevents the component P that has moved from the first inclined surface 44 to the second inclined surface 45 from moving toward the component alignment section 43. For example, at least a portion of the second inclined surface 45 is inclined downward in the opposite direction to the component alignment section 43. Note that the second inclined surface 45 is not limited to being inclined.

[0061] 5B, second inclined surface 45 may be a surface parallel to support surface 43a of component alignment unit 43, and disposed on the positive side of the Z axis relative to support surface 43a. In this case, second inclined surface 45 may be provided with a plurality of air ejection holes so that air can be ejected upward toward the opposite side of component alignment unit 43 (negative side of the Y axis) in the cross section shown in FIG.

[0062] The length of the second inclined surface 45 in the Y-axis direction is, for example, longer than the length of the component alignment section 43. The length of the second inclined surface 45 in the Y-axis direction is, for example, longer than the length of the long side of the component P.

[0063] Furthermore, although Figure 4A shows an example in which the first inclined surface 44 and the second inclined surface 45 are directly connected, for example, a switching section may be provided between the first inclined surface 44 and the second inclined surface 45, which gradually switches the inclination angle from the first inclined surface 44 to the second inclined surface 45 from the component supply position 42 side (upstream side) to the supply section 50 side (downstream side).

[0064] The first conveying portion 40a1 includes at least a first inclined surface 44. The first conveying portion 40a1 may further include a second inclined surface 45.

[0065] The cover 46 is disposed at a position corresponding to the end of the first conveying section 40a1 (e.g., the second inclined surface 45) on the take-out position side in the first direction (the end on the positive side of the X-axis), with a predetermined gap in the Z-axis direction from the support surface 43a of the component alignment section 43, and covers the upper part of the component alignment section 43. It can also be said that the cover 46 covers part of the component alignment section 43 and the component straight-travel section 53. For example, when there are components P that are overlapping in the vertical direction (Z-axis direction) in the component alignment section 43, the cover 46 is provided to prevent the components P from being transported to the supply section 50 in an overlapping state. The predetermined gap is, for example, a distance that allows the cover 46 to contact the upper component without contacting the lower component when there are components P that are overlapping in the vertical direction in the component alignment section 43.

[0066] The cover 46 has a shape that allows it to move the upper component to the swivel unit 47. For example, the end face of the cover 46 on the negative X-axis side comes into contact with the upper component, thereby moving the upper component to the swivel unit 47. The surface on the negative X-axis side of the cover 46 may be, for example, an inclined surface that inclines in the positive X-axis direction as it moves from the positive Y-axis side to the negative Y-axis side (moving away from the component alignment unit 43) in a plan view. Furthermore, the inclined surface may be formed with a plurality of air ejection holes that eject air toward the negative Y-axis side.

[0067] The components are transported from the transport section 40 to the supply section 50 by passing through the component alignment section 43 which is formed into a tunnel by the cover 46 .

[0068] The swivel section 47 is a section (area) for moving the components from the second inclined surface 45 and the cover 46 to the return conveyance section 48, and is connected to both the second inclined surface 45 and the return conveyance section 48. The swivel section 47 conveys the components P in the conveyance direction d2 shown in FIG. 4B. The swivel section 47 has a plurality of air ejection holes formed therein for moving the components. Note that the swivel section 47 is a flat surface, but may have at least a portion that is inclined, for example.

[0069] The return conveyance section 48 is connected to the second inclined surface 45 and is provided along the first conveyance portion 40a1. The return conveyance section 48 conveys components P in a second direction (the negative X-axis direction) opposite to the first direction. The return conveyance section 48 conveys components P in the conveyance direction d3 shown in FIG. 4B. The return conveyance section 48 is provided to return components not aligned by the component alignment section 43 to the component supply position 42. The return conveyance section 48 has a plurality of air outlets (not shown) formed in a support surface that supports the components of the return conveyance section 48. The return conveyance section 48 conveys components to the component supply position 42 by ejecting air in a second upward direction from the plurality of air outlets. The pressure or flow rate of the air ejected from the plurality of air outlets of the return conveyance section 48 may be higher or the same as the pressure or flow rate of the air ejected from the plurality of air outlets of the component alignment section 43, the first inclined surface 44, and the second inclined surface 45. The air ejection holes formed in the support surface of the return conveying section 48 are an example of second air ejection holes.

[0070] The support surface of the return conveying section 48 may be, for example, an inclined surface that slopes upward (in the positive direction of the Z axis) from the turning section 47 toward the component supply position 42. In other words, the component may be conveyed by the return conveying section 48 from the turning section 47 to the component supply position 42, which is located at a higher position than the turning section 47.

[0071] The second conveying portion 40a2 is configured to include the return conveying section 48. It can also be said that the second conveying portion 40a2 has a plurality of air ejection holes (an example of a second air ejection hole) that open to a support surface (an example of a third support surface) on which the components of the second conveying portion 40a2 are supported and that are configured to be able to eject air in a second direction and upward.

[0072] Side walls 49a and 49c and partition wall 49b are wall portions that extend in a first direction and form first conveying portion 40a1 and second conveying portion 40a2. Side wall 49a and partition wall 49b form first conveying portion 40a1, and partition wall 49b and side wall 49c form second conveying portion 40a2. Partition wall 49b also functions as a partition that prevents air ejected from one of first conveying portion 40a1 and second conveying portion 40a2 from flowing into the other.

[0073] The side walls 49a and 49c and the partition wall 49b may be integrally formed, for example, which means that there does not need to be a gap between the first transport portion 40a1 and the second transport portion 40a2.

[0074] Furthermore, for example, when components are conveyed by vibration on the first conveying section 40a1 and the second conveying section 40a2, the vibration conditions are different, so a gap is formed between the first conveying section 40a1 and the second conveying section 40a2, which can cause problems such as an increase in the width of the conveying section or components getting caught in the gap.

[0075] On the other hand, in the conveying unit 40 according to the present embodiment, as described above, no gap is formed between the first conveying portion 40a1 and the second conveying portion 40a2. Therefore, the positions of the first conveying portion 40a1 and the second conveying portion 40a2 can be brought closer to each other, and the width (length in the Y-axis direction) of the conveying unit 40 can be reduced. In other words, the component supply device 30 can be made smaller. Also, it is possible to prevent components from getting caught in the gap. For example, it is possible to smoothly rotate the components at the rotating unit 47.

[0076] As described above, the conveying section 40 includes the first conveying portion 40a1 that conveys components in a first direction toward the supplying section 50, and the second conveying portion 40a2 that is provided along the first conveying portion 40a1 and conveys components from the first conveying portion 40a1 in a second direction opposite to the first direction. The first conveying portion 40a1 and the second conveying portion 40a2 form a circular path.

[0077] The first conveying portion 40a1 is not formed in the supplying portion 50. In other words, the length of the first conveying portion 40a1 in the first direction is shorter than the total length of the component alignment portion 43 and the component straight-line portion 53 in the first direction (an example of the length of the alignment portion in the first direction).

[0078] Next, the supply unit 50 will be further described with reference to Figures 6A and 6B. Figure 6A is a cross-sectional view showing the VIa-VIa cross section shown in Figure 4A(a). Figure 6B is a perspective view showing the portion enclosed by the dashed line VIb shown in Figure 4A(a). Note that Figures 6A and 6B omit the illustration of the multiple air ejection holes formed in the support surface (bottom surface). Furthermore, Figure 6B omits the illustration of the side wall 54a.

[0079] 3, the supply unit 50 of the component supply device 30 has a main body 50a and a lid 50b. The lid 50b covers the main body 50a and is fixed to the main body 50a by fastening members 38 such as screws.

[0080] 3 and 4A, the main body 50a has a first sensor 51 (see FIG. 2), a component straight-line section 53, and side walls 54a and 54b. The first sensor 51 is provided, for example, near the entrance of the component straight-line section 53 (near the supply section entrance 52) and detects components passing through the supply section entrance 52. The side walls 54a and 54b are an example of a side member.

[0081] The component straight-line section 53 is connected to the component alignment section 43, and supplies the components to the removal position by conveying the aligned components from the conveying section 40 to the removal position. The component alignment section 43 conveys the aligned components P from the conveying section 40 in the conveying direction d1 shown in FIG. 4B. The component straight-line section 53 is provided to extend in the first direction.

[0082] As shown in (c) of FIG. 4A, multiple air ejection holes 53b are formed in the support surface 53a of the component straight-line section 53. The component straight-line section 53 sequentially transports multiple components using air ejected from the multiple air ejection holes 53b. The component straight-line section 53 can simultaneously transport multiple components using the multiple air ejection holes 53b. Note that in (c) of FIG. 4A, a portion of the air passage that connects the second air supply section 63 and the air ejection hole 53b is shown by a dashed line in the air ejection hole 53b on the positive side of the X-axis.

[0083] As shown in FIG. 6A, the component straightening section 53 is a concave groove extending in the first direction. The support surface 53a of the component straightening section 53 is formed by the bottom surface of the groove and supports the component. The support surface 53a is connected to the support surface 43a of the component alignment section 43 and is flush with the support surface 43a. The support surface 53a is formed with multiple air ejection holes 53b for floating and transporting the component in the first direction. The multiple air ejection holes 53b formed in the support surface 53a are configured to eject air upward in the first direction. In other words, the multiple air ejection holes 53b formed in the support surface 53a eject air diagonally upward toward the first direction when viewed from the Y-axis direction. Furthermore, the multiple air ejection holes 53b formed in the support surface 53a eject air perpendicular to the support surface 53a when viewed from the X-axis direction.

[0084] If the component is a rectangular parallelepiped, the width (length in the Y-axis direction) of the component straight-line portion 53 is greater than the length of the shortest side of the component and less than the length of the longest side of the component. The width of the component straight-line portion 53 may be the same as the width of the component alignment portion 43. This prevents the component from contacting a wall surface or the like at the boundary (connection point) between the component straight-line portion 53 and the component alignment portion 43, which is effective in preventing the component from blackening.

[0085] The part straight-advancing section 53 has two side walls 54a and 54b arranged opposite to each other with a gap in the width direction of the support surface 53a. One of the two side walls 54a and 54b (side wall 54b in the example of FIGS. 6A and 6B) has a plurality of air outlets 54b2 that eject air toward the other of the two side walls 54a and 54b (side wall 54a in the example of FIGS. 6A and 6B). When the part straight-advancing section 53 is a groove, the plurality of air outlets 54b2 are formed in one of the opposing wall surfaces 54a1 and 54b1 (wall surface 54b1 in the example of FIGS. 6A and 6B) of the pair of side walls that form the groove. The plurality of air outlets 54b2 are provided in the wall surface 54b1 along the first direction. While air is being ejected from the plurality of air ejection holes 53b on the support surface 53a of the part straight-traveling portion 53, air is also ejected from the plurality of air ejection holes 54b2.

[0086] The multiple air ejection holes 54b2 are provided so that they can eject air onto components being floated and transported by the component straight-line section 53. The multiple air ejection holes 54b2 are provided, for example, at a height that allows them to eject air onto the components. Note that the pressure or flow rate of the air ejected from the air ejection holes 54b2 may be lower than the pressure or flow rate of the air ejected from the air ejection holes 53b. The air ejection holes 54b2 are an example of a third air ejection hole.

[0087] 6B, component straight-line section 53 has wall section 55 at the end of component straight-line section 53 in the first direction, which abuts against the end face of the component in the first direction. Wall section 55 abuts against the component, thereby stopping the transport of the component in the first direction. Wall section 55 has the function of positioning the component at removal position 56.

[0088] Wall 55 is formed with suction holes 55a for sucking air. The surface of the component transported to removal position 56 facing the first direction is sucked by suction holes 55a, so that the component is firmly positioned on wall 55. This fixes the component at the removal position. Air suction by suction holes 55a may also assist in transporting the component to removal position 56. Air suction by suction holes 55a may also attract the component to removal position 56. In this way, suction holes 55a may have the function of transporting the component in addition to the function of positioning the component.

[0089] For example, air ejection holes 53b are formed all the way up to removal position 56. In other words, suction holes for fixing components cannot be provided at the removal position on support surface 53a of component straight-line section 53. In such a case, by providing suction holes 55a in wall section 55, the component can be fixed in the desired position without interfering with the floating transport of the component.

[0090] The suction hole 55a is an example of a suction unit that suctions the end face of the component on the first direction side (the end face on the positive side of the X-axis). Note that the suction unit is not limited to suctioning the component by air, and may be configured to suction the component by electrostatic force, magnetic force, or adhesive force. Any existing configuration may be used for suctioning the component by electrostatic force, magnetic force, or adhesive force. For example, when suctioning the component by electrostatic force, the suction unit includes one or more electrodes for generating electrostatic force. Then, the component may be suctioned (e.g., adhered) to the wall 55 by electrostatic force generated between the one or more electrodes and the component by applying a DC voltage to the one or more electrodes by the control unit 61.

[0091] The component straight-line section 53 and the component alignment section 43 form an alignment section in the component supply device 30. The alignment section aligns the components supplied from the case 10 and transports them to the take-out position. For example, the multiple air ejection holes are configured to eject air upward in a first direction from the case 10 toward the take-out position 56 in the alignment section and the first inclined surface 44, respectively. The multiple air ejection holes here include air ejection holes 43b, 44b, and 53b. For example, the air ejection holes 43b and 53b are examples of first air ejection holes, and the air ejection hole 44b is an example of a second air ejection hole. The component straight-line section 53 forms a downstream section of the alignment section on the take-out position 56 side in the first direction.

[0092] The control unit 61 may turn off the air suction through the suction holes 55a at the timing when the mounting head 107 picks up the component.

[0093] As described above, in component supply device 30, components P are conveyed in the directions of the arrows (conveying directions d1 to d4). For example, after being supplied to component supply position 42, components P are conveyed to component alignment section 43 and first inclined surface 44. Components P on first inclined surface 44 are moved to component alignment section 43 by air. Components P on component alignment section 43 are conveyed to component straight-line section 53 by air. In this way, some of the components P are conveyed in the order of component supply position 42, component alignment section 43, and component straight-line section 53, as indicated by the straight arrow (conveying direction d1) passing through component supply position 42 and component straight-line section 53.

[0094] Furthermore, components P that do not fall from first inclined surface 44 onto component alignment section 43 are conveyed to second conveying section 40a2 via turning section 47. Components P on second conveying section 40a2 are conveyed upstream of component alignment section 43 and component straight-line section 53, and then conveyed again to component alignment section 43 and first inclined surface 44. In this way, some of the components P are conveyed circularly through component alignment section 43, turning section 47, return conveying section 48, and component supply position 42 in that order, as indicated by the circular arrow (arrow group) passing through component alignment section 43, turning section 47, return conveying section 48, and component supply position 42.

[0095] FIG. 7 is a block diagram showing the functional configuration of the component supply device 30 according to this embodiment.

[0096] As shown in FIG. 7, the component supply device 30 has, as its functional configuration, the first sensor 51, the second sensor 41, the control unit 61, the first air supply unit 62, and the second air supply unit 63, as described above.

[0097] [2. Operation of parts supply device] Next, the operation of the component supply device 30 configured as above will be described with reference to Figures 8 to 9D. Figure 8 is a flowchart showing the operation of the component supply device 30 according to this embodiment.

[0098] 8, the control unit 61 determines whether or not production has started, which requires the operation of the component supply device 30 (S10). The control unit 61 may determine that production has started, for example, when the operation of a mounting system to which the component supply device 30 is attached has started, or may determine that production has started by obtaining information indicating that production has started from a higher-level control device.

[0099] Next, when production has started (Yes in S10), the control unit 61 controls the transport of components in the transport unit 40 and the transport of components in the supply unit 50 independently of each other (S20). In other words, the control unit 61 does not uniformly control the transport of components in the transport unit 40 and the supply unit 50. In this embodiment, the control unit 61 controls the air transport of components in the transport unit 40 and the air transport of components in the supply unit 50 independently of each other.

[0100] Next, the control unit 61 determines whether or not the production has ended (S30). The control unit 61 may determine that the production has ended, for example, when the operation of the component mounting device to which the component supply device 30 is attached has ended, or may determine that the production has ended by acquiring information indicating that the production has ended from a higher-level control device, or may determine that the production has ended when the number of components detected by the first sensor 51 exceeds a predetermined number.

[0101] Next, if production has ended (Yes in S30), the control unit 61 stops controlling the transport of parts in the transport unit 40 and the transport of parts in the supply unit 50 (S40), and if production has not ended (No in S30), returns to step S20 and continues processing in step S20.

[0102] Next, the control unit 61 ends the operation after executing the process of step S40, or if production has not started (No in S10).

[0103] The control of step S20 will now be described with reference to Figures 9A to 9D. Figure 9A is a diagram showing a first example of step S20 shown in Figure 8. Figure 9A shows an operation in a state where the supply of air to the transfer unit 40 is stopped. Note that air may be supplied to the supply unit 50 during the operation shown in Figure 9A.

[0104] The control unit 61 acquires a detection result indicating whether or not there is a component in the supply unit 50 from the first sensor 51 (S21). The control unit 61 acquires the detection result from the first sensor 51, for example, at predetermined time intervals.

[0105] Next, if the control unit 61 determines based on the detection result that there are no components in the supply unit 50 (No in S22), it supplies air to the conveyance unit 40 (S23). For example, if the determination in step S22 is No, it can be said that the control unit 61 starts supplying air to the conveyance unit 40. Specifically, the control unit 61 controls the first air supply unit 62, etc. to eject air from the air ejection holes of the conveyance unit 40. The control unit 61 integrally controls the supply of air to, for example, the component supply position 42, the component alignment unit 43, the first inclined surface 44, the second inclined surface 45, the swiveling unit 47, and the return conveyance unit 48. For example, in step S23, the control unit 61 ejects air from all of the multiple air ejection holes formed in the conveyance unit 40.

[0106] In this way, the control unit 61 may control the transport of parts in the transport unit 40 based on, for example, the detection result of the first sensor 51. When the control unit 61 obtains a detection result from the first sensor 51 indicating that there are no parts in the supply unit 50 (for example, a detection result indicating that there are no parts in a predetermined position in the supply unit 50), the control unit 61 causes the transport unit 40 to transport the parts.

[0107] FIG. 9B is a diagram showing a second example of step S20 shown in FIG.

[0108] As shown in FIG. 9B, when production starts (Yes in S10), the control unit 61 supplies air to the supply unit 50 (S24). Specifically, the control unit 61 controls the second air supply unit 63 and the like to eject air from at least the air ejection holes 53b of the supply unit 50. For example, in step S24, the control unit 61 ejects air from each of the air ejection holes 53b and 54b2. The control unit 61 may integrally control the supply of air to each of the air ejection holes 53b and 54b2. Furthermore, in step S24, the control unit 61 may cause the suction holes 55a to suck air.

[0109] In this way, the control unit 61 may, for example, control the transport of components in the supply unit 50 regardless of the detection result of the first sensor 51. For example, when the component mounting apparatus 100 described below is operating, the control unit 61 may perform control to always supply components to the removal position of the supply unit 50. For example, when the component mounting apparatus 100 is operating, the control unit 61 may perform control to supply air from the second air supply unit 63 to the multiple air ejection holes 53b.

[0110] FIG. 9C is a diagram showing a third example of step S20 shown in FIG.

[0111] 9C, the control unit 61 may perform the operations of steps S25 to S27 in addition to the operations shown in Fig. 9A. If there are no components in the supply unit 50 (No in S22), the control unit 61 supplies air to the supply unit 50 for a predetermined period (S25). For example, if the result in step S22 is No, the control unit 61 does not immediately supply air to the conveying unit 40, but continues to supply air to the supply unit 50 for a predetermined period. At this time, air is not being supplied to the conveying unit 40.

[0112] Next, the control unit 61 acquires the detection result after supplying air to the supply unit 50 from the first sensor 51 (S26). If the control unit 61 determines based on the detection result acquired in step S26 that there is no component in the supply unit 50 (No in S27), it supplies air to the conveying unit 40 (S23), and if there is a component in the supply unit 50 (Yes in S27), it does not supply air to the conveying unit 40.

[0113] In this way, for example, if there is no part at a specified position in the supply unit 50, the control unit 61 may cause the supply unit 50 to transport the part for a specified period of time, and if there is still no part at the specified position after the specified period of time, the control unit 61 may cause the transport unit 40 to transport the part.

[0114] As a result, the transport unit 40 transports components only when there are no components reliably present in the supply unit 50, which further reduces blackening of the components due to contact with the components in the transport unit 40, etc.

[0115] FIG. 9D is a diagram showing a fourth example of step S20 shown in FIG.

[0116] As shown in FIG. 9D, when production starts (Yes in S10), the control unit 61 may supply air to the alignment unit and the first conveying portion 40a1 (S28).

[0117] Furthermore, the control unit 61 may perform control to supply components from the case 10 based on, for example, the detection result of the second sensor 41. For example, when the control unit 61 obtains a detection result from the second sensor 41 indicating that there are no components on the conveying unit 40 (for example, a detection result indicating that there are no components at a predetermined position on the conveying unit 40), the control unit 61 may vibrate the case 10 to supply the components to the component supply position 42. For example, when there are no components at a predetermined position on the conveying unit 40, the control unit 61 may cause the conveying unit 40 to convey the components for a predetermined period of time, and if there are still no components at the predetermined position after the predetermined period, the control unit 61 may supply the components from the case 10 to the component supply position 42 because there are no components on the conveying unit 40.

[0118] In this way, the control unit 61 may control the transport of parts in the transport unit 40 based on the detection results of the second sensor 41, and may also control the transport of parts in the supply unit 50 regardless of the detection results of the second sensor 41.

[0119] [3. Configuration of component mounting equipment] Next, a component mounting apparatus 100 to which a supply unit 80 having the component supply device 30 described above is attached will be described with reference to FIG. 10. FIG. 10 is a diagram showing the configuration of the component mounting apparatus 100 according to this embodiment. An example of the component mounting apparatus 100 will be described, which is an apparatus that mounts components on a substrate 103. The component mounting apparatus 100 has a function of picking up components from a feeder that supplies components, and transferring and mounting the components on the substrate 103. The substrate 103 is an example of an object on which components are to be mounted.

[0120] As shown in FIG. 10, the component mounting apparatus 100 includes a supply unit 80, a base 101, a substrate conveying mechanism 102, a component mounting mechanism 108 including a mounting head 107, a substrate recognition camera 109, a component recognition camera 110, and a power supply unit (not shown).

[0121] The substrate transport mechanism 102 is disposed near the center of the base 101 along the X-axis (the transport direction of the substrate 103). The substrate transport mechanism 102 transports the substrate 103 carried in from the upstream side in the direction along the X-axis, and positions and holds the substrate 103 on a mounting stage set for performing component mounting work. The substrate transport mechanism 102 is an example of a substrate holder that holds the substrate 103 on which components held by the mounting head 107 will be mounted.

[0122] The supply unit 80 is detachably mounted to a supply unit mounting portion (not shown) of the base 101, which is the main body of the component mounting apparatus 100. More specifically, the carriages 70 constituting the supply unit 80 are mounted to the supply unit mounting portion. In this embodiment, the supply unit mounting portions are provided on both sides of the board transport mechanism 102, and the supply units 80 are also disposed on both sides of the board transport mechanism 102. Each supply unit 80 can have a plurality of feeders 20 arranged in parallel along the Y axis, and at least one feeder 20 (bulk feeder) is mounted in parallel. Furthermore, by mounting the supply unit 80 to the base 101, each functional portion of the supply unit 80 (e.g., the first air supply unit 62 and the second air supply unit 63, etc.) is electrically connected to a power supply unit, and power is supplied from the power supply unit to each functional portion of the supply unit 80.

[0123] Feeder 20 disposed in supply unit 80 supplies components to a take-out position (take-out position 56 shown in FIG. 6B) by mounting head 107 of component mounting mechanism 108. Mounting head 107 is an example of a head.

[0124] An X-axis moving table 105 equipped with a linear drive mechanism is disposed in the X-axis direction at the end in the negative Y-axis direction on the upper surface of base 101, and two Y-axis moving tables 106 similarly equipped with linear drive mechanisms are coupled to X-axis moving table 105 so as to be freely movable in the X-axis direction. A mounting head 107 is attached to each of the two Y-axis moving tables 106 so as to be freely movable in the Y-axis direction.

[0125] The mounting head 107 places (mounts) components held by the feeders 20 arranged in the supply unit 80 onto the board 103. The mounting head 107 mounts the components onto the board 103 based on the detection result of the third sensor 64, for example.

[0126] The mounting head 107 is equipped with component suction nozzles 107a that can pick up and hold components and move up and down independently. The mounting head 107 is equipped with a Z-axis lifting mechanism that lifts and lowers the component suction nozzles 107a and a θ-axis rotation mechanism that rotates the component suction nozzles 107a around the nozzle axis. The component suction nozzles 107a are an example of a holder that holds components.

[0127] By driving the X-axis moving table 105 and the Y-axis moving table 106, the mounting head 107 moves in the X-axis and Y-axis directions. As a result, the two mounting heads 107 use the component suction nozzles 107a to pick up components from the pick-up positions of the feeders 20 arranged in the corresponding supply units 80. The board transport mechanism 102, the X-axis moving table 105, the Y-axis moving table 106, and the mounting heads 107 form a component mounting mechanism 108. The X-axis moving table 105 and the Y-axis moving table 106 are an example of a drive unit that moves the mounting heads 107.

[0128] A component recognition camera 110 is disposed between each of the upper and lower carriages 70 and the board transport mechanism 102. When the mounting head 107, which has picked up a component from the feeder 20 arranged in the supply unit 80, moves above the component recognition camera 110, the component recognition camera 110 captures an image of the component held by the mounting head 107. The captured image is processed by image recognition in a processing unit (not shown), thereby identifying the component and detecting its position.

[0129] The mounting heads 107 are equipped with board recognition cameras 109 that are positioned below the Y-axis moving table 106 and move integrally with the mounting heads 107. As the mounting heads 107 move, the board recognition cameras 109 move above the boards 103 positioned by the board transport mechanism 102 and capture images of the boards 103. The image capture results are similarly recognized and processed by the image recognition processing unit, thereby detecting the position of the boards 103.

[0130] The power supply unit supplies power to each functional unit of the component mounting apparatus 100. The power supply unit supplies power to, for example, the supply unit 80 disposed in the substrate transport mechanism 102. Specifically, the power supply unit supplies power to the first air supply unit 62 and the second air supply unit 63 of the supply unit 80. The power supply unit may also be connected to an external power source.

[0131] [4. Effects etc.] A component supplying device 30 according to one embodiment of the present disclosure is a component supplying device that supplies components stored in a bulk state in a case 10 (an example of a component storage section) to a removal position 56 where the components are removed by a holding section that holds the components. The component supplying device 30 includes a component alignment section 43 and a component straight-travel section 53 (an example of an alignment section) that align the components supplied from the case 10 and transport them to the removal position 56, and a first transport section 40a1 that is provided along the component alignment section 43 and the component straight-travel section 53 and has a first inclined surface 44 that slopes downward toward the component alignment section 43 and the component straight-travel section 53. The component alignment section 43, the component straight-line section 53, and the first transport section 40a1 have a plurality of air ejection holes 43b, 44b, and 53b (an example of a first air ejection hole) that open to the component alignment section 43, the component straight-line section 53, and the first inclined surface 44 on which the components of the first transport section 40a1 are supported, and that eject air to float and transport the components. The plurality of air ejection holes 43b, 44b, and 53b may be configured to eject air upward in a first direction (the positive direction of the X-axis) from the case 10 toward the removal position 56, respectively, at the component alignment section 43, the component straight-line section 53, and the first inclined surface 44.

[0132] For example, when a propulsive force is applied to a component by vibration, the propulsive force is applied in the negative X-axis direction, the Y-axis direction, etc., in addition to the positive X-axis direction, which can cause contact between front and rear components, or between a component and a wall. Furthermore, when aligning components by abutting them against an alignment wall (e.g., a tapered wall in a plan view), contact between the component and the wall can occur. In other words, when components are transported using vibration or an alignment wall, blackening of the components can occur during transport.

[0133] On the other hand, the component supply device 30 according to this embodiment transports components using air from above in the first direction (positive X-axis direction), so it can reliably apply a propulsive force to the components only in the first direction (positive X-axis direction). For example, compared to when propulsive force is applied to the components by vibration, it is possible to prevent components from moving in the negative X-axis direction, etc., and thus prevent components from coming into contact with each other. Furthermore, because air is also ejected onto the first inclined surface 44, it is possible to move and align components on the first inclined surface 44 to the component alignment section 43 while reducing friction between the components and the first inclined surface 44. For example, compared to when components are aligned using an alignment wall, it is possible to prevent components from coming into contact with structures such as walls. Therefore, the component supply device 30 according to one aspect of the present disclosure can prevent components from blackening during transport.

[0134] Furthermore, for example, first conveying portion 40a1 may further include second inclined surface 45 that slopes downward in the opposite direction to component alignment section 43 and component straight-travel section 53. Second inclined surface 45 may be provided downstream of first inclined surface 44 in the first direction.

[0135] This makes it possible to prevent components from clogging downstream of the component alignment section 43 and the component straight-travel section 53 (for example, at the component straight-travel section 53).

[0136] Furthermore, for example, a cover 46 may be further provided that covers a portion of the upper part of the component alignment section 43 and the component straight traveling section 53 at a predetermined gap from support surfaces 43a and 53a (an example of a first support surface) on which the components of the component alignment section 43 and the component straight traveling section 53 are supported. The length of the first transport section 40a1 in the first direction may be shorter than the lengths of the component alignment section 43 and the component straight traveling section 53 in the first direction, and the cover 46 may be provided at a position corresponding to the end of the first transport section 40a1 on the side of the removal position 56 in the first direction.

[0137] As a result, when parts are transported stacked one on top of the other in the vertical direction, the cover 46 can release the parts from the stacked state.

[0138] Also, for example, the conveying mechanism may further include a second conveying portion 40a2 connected to the second inclined surface 45, provided along the first conveying portion 40a1, and configured to convey components in a second direction (the negative X-axis direction) opposite to the first direction. The second conveying portion 40a2 may have a plurality of air ejection holes (an example of second air ejection holes) that open to a support surface (an example of a third support surface) on which the components of the second conveying portion 40a2 are supported and that are configured to eject air in the second direction and upward.

[0139] This allows components to be conveyed by air also on second conveying section 40a2, so that components that were not conveyed by component alignment section 43 and component straight-line section 53 can be returned to the upstream side of component alignment section 43 and component straight-line section 53 while suppressing friction between the components and the support surfaces of second conveying section 40a2. Therefore, the components can be returned to the upstream side while suppressing blackening of the components.

[0140] Furthermore, for example, downstream portions of component alignment section 43 and component straight traveling section 53 on the take-out position 56 side in the first direction may have two side walls 54a and 54b (an example of side members) arranged to face each other and spaced apart in the width direction (Y-axis direction) of support surfaces 43a and 53a of component alignment section 43 and component straight traveling section 53. One side wall 54b of the two side walls 54a and 54b may have a plurality of air ejection holes 54b2 (an example of third air ejection holes) that eject air toward the other side wall 54a of the two side walls 54a and 54b.

[0141] As a result, in the downstream portion of the component alignment section 43 and the component straight-line section 53 (for example, at the component straight-line section 53), the components can be moved (positioned) against the side wall 54a by air, which makes it possible to prevent the components from coming into contact with other objects compared to when the components are moved against the side wall 54a by a structure such as a wall. Therefore, the component supply device 30 can move the components against the side wall 54a while preventing the components from blackening during transport.

[0142] Furthermore, for example, the component alignment section 43 and the component straightening section 53 may have a wall section 55 at the end of the component alignment section 43 and the component straightening section 53 in the first direction that abuts against the end face of the component on the first direction side, and the wall section 55 may have an adsorption section (for example, an adsorption hole 55a that sucks air) that adsorbs the end face of the component.

[0143] As a result, even if multiple air outlet holes are formed on support surfaces 43a and 53a (e.g., support surface 53a) and an adsorption portion cannot be formed on support surface 53a, the component can be fixed to removal position 56 by an adsorption portion (e.g., adsorption hole 55a) formed on wall portion 55.

[0144] Also, for example, suction holes 55a for sucking air may be formed in the wall portion 55, and a third sensor 64 (an example of a sensor) may be further provided for measuring the flow rate or vacuum level in an air path connected to the suction holes 55a.

[0145] This allows the presence or absence of a component at the removal position 56 to be determined based on the flow rate or vacuum level in the air path. In other words, the presence or absence of a component can be determined without contact. Therefore, the component supply device 30 can prevent the component from blackening compared to when the presence or absence of a component is determined using a contact-type sensor.

[0146] Furthermore, for example, component alignment section 43 and component straightness section 53 may be grooves extending in the first direction.

[0147] This allows the component supply device 30 to align the components more effectively in the grooves.

[0148] Furthermore, a component supply method according to one embodiment of the present disclosure is a component supply method in a component supply device 30 that supplies components stored in a bulk state in a case 10 to a removal position 56 where the components are removed by a holding unit that holds the components. The component supply device 30 may include a component alignment unit 43 and a component straight advancement unit 53 that align the components supplied from the case 10 and transport them to the removal position 56, and a first transport section 40a1 that is provided along the component alignment unit 43 and the component straight advancement unit 53 and has a first inclined surface 44 that slopes downward toward the component alignment unit 43 and the component straight advancement unit 53. Furthermore, component alignment section 43, component straight-line section 53, and first conveying section 40a1 have a plurality of air ejection holes 43b, 44b, and 53b (an example of a first air ejection hole) that open to component alignment section 43, component straight-line section 53, and first inclined surface 44 on which components of first conveying section 40a1 are supported, and that eject air to float and convey the components. The component supply method may include ejecting air upward in a first direction from case 10 toward removal position 56 at component alignment section 43, component straight-line section 53, and first inclined surface 44, respectively.

[0149] This provides the same effects as the component supply device 30 described above.

[0150] Furthermore, component supply device 30 according to one embodiment of the present disclosure is a component supply device that supplies components stored in a bulk state in case 10 to removal position 56, where the components are removed by a holding unit that holds the components. Component supply device 30 may include a conveying unit 40 that aligns and conveys the components supplied from case 10, a supplying unit 50 that is connected at one end to conveying unit 40 and supplies the components conveyed from conveying unit 40 to removal position 56, and a control unit 61 that independently controls the conveying of components by conveying unit 40 and the conveying of components by supplying unit 50.

[0151] As a result, the component transport in the transport unit 40 and the component transport in the supply unit 50 are controlled independently of each other, which reduces contact between the components compared to when the two transports are controlled integrally. Therefore, the component supply device 30 according to one embodiment of the present disclosure can reduce blackening of the components during transport.

[0152] Also, for example, a first sensor 51 (an example of a first detection unit) may be provided to detect the amount of components stored in the supply unit 50. Then, the control unit 61 may control the transport of components in the transport unit 40 based on the detection result of the first sensor 51.

[0153] As a result, the transport of components in the transport unit 40 is controlled according to the amount of components in the supply unit 50, and the number of times or transport time of components in the transport unit 40 can be reduced compared to when the transport unit 40 is controlled regardless of the amount of components in the supply unit 50. In other words, excessive transport of components in the transport unit 40 is suppressed, and contact between components during transport in the transport unit 40 can be suppressed. Therefore, the component supply device 30 according to one embodiment of the present disclosure can further suppress blackening of components during transport.

[0154] Also, for example, the first sensor 51 may detect whether or not a part is present at a predetermined position in the supply section 50, and the control section 61 may cause the conveying section 40 to convey the part when it obtains a detection result from the first sensor 51 indicating that a part is not present at the predetermined position.

[0155] As a result, when there are no components at the predetermined positions in the supply unit 50, that is, when it is necessary to transport a component from the transport unit 40 to the supply unit 50, the transport unit 40 transports the component. In other words, when there are components at the predetermined positions in the supply unit 50, that is, when it is not necessary to transport a component from the transport unit 40 to the supply unit 50, the transport unit 40 does not transport the component. Therefore, since it is possible to limit the transport of components by the transport unit 40 to when there are no components at the predetermined positions in the supply unit 50, the component supply device 30 can prevent the components from coming into contact with the transport unit 40 and causing blackening of the components.

[0156] Furthermore, for example, if there is no part at the specified position, the control unit 61 may further cause the supply unit 50 to transport the part for a specified period of time, and if there is still no part at the specified position after the specified period of time, the control unit 61 may cause the transport unit 40 to transport the part.

[0157] This allows the conveying unit 40 to convey components only when there is no component in the predetermined position. Therefore, the component supply device 30 can further prevent the components from blackening in the conveying unit 40.

[0158] Further, for example, the control unit 61 may control the transportation of components in the supply unit 50 regardless of the detection result of the first sensor 51.

[0159] This allows the supply unit 50 to transport components under constant conditions regardless of the detection result of the first sensor 51. Therefore, the supply unit 50 can more reliably supply components to the removal position 56.

[0160] Furthermore, for example, the transport unit 40 may have a plurality of air ejection holes 43b opening in a support surface 43a (an example of a first support surface) that supports the components, the plurality of air ejection holes 43b for ejecting air to float and transport the components, and the supply unit 50 may have a plurality of air ejection holes 53b opening in a support surface 53a (an example of a second support surface) that supports the components, the plurality of air ejection holes 53b for ejecting air to float and transport the components. The control unit 61 may control the air ejected from the plurality of air ejection holes 43b and the air ejected from the plurality of air ejection holes 53b independently of each other.

[0161] This allows the components to be transported in a floating manner, thereby reducing friction between the components and the support surfaces 43a and 53a. Furthermore, since the air ejected from the plurality of air ejection holes 43b and the air ejected from the plurality of air ejection holes 53b are controlled independently of each other, more flexible control is possible, such as stopping the supply of one of the air sources, compared to when the two air sources are controlled integrally. By stopping the air supply, contact between the components in the relevant components can be reduced. Therefore, the component supply device 30 according to one embodiment of the present disclosure can further reduce blackening of the components during transport.

[0162] Furthermore, for example, the conveying section 40 may have a first conveying portion 40a1 that conveys parts in a first direction from the case 10 toward the supply section 50, and a second conveying portion 40a2 that is connected to the first conveying portion 40a1 and arranged along the first conveying portion 40a1 and that conveys parts from the first conveying portion 40a1 in a second direction opposite to the first direction.

[0163] This allows components that were not transported from the transport section 40 to the supply section 50 to be returned to the upstream side of the transport section 40 (the negative side of the X axis).

[0164] Furthermore, for example, the conveying section 40 may further include a component aligning section 43 that is provided along the first conveying portion 40a1 and that aligns the components being conveyed in the first direction.

[0165] This allows the components aligned by the component alignment unit 43 to be supplied to the supply unit 50.

[0166] Also, for example, a second sensor 41 (an example of a second detection unit) that detects the amount of parts on the first transport portion 40a1 may be further provided. Then, the control unit 61 may perform control to supply parts from the case 10 based on the detection result of the second sensor 41.

[0167] This increases the density of components at the position where the components are supplied from the case 10, and the component supply device 30 can prevent the components from coming into contact with each other.

[0168] Furthermore, a component supply method according to one aspect of the present disclosure is a component supply method for a component supply device 30 that supplies components stored in a bulk state in a case 10 to a removal position 56 where the components are removed by a holding unit that holds the components. The component supply device 30 may include a conveying unit 40 that aligns and conveys the components supplied from the case 10, and a supply unit 50 that is connected at one end to the conveying unit 40 and supplies the components conveyed from the conveying unit 40 to the removal position 56. The component supply method may include controlling the conveyance of components in the conveying unit 40 and the conveyance of components in the supply unit 50 independently of each other.

[0169] This provides the same effects as the component supply device 30 described above.

[0170] Furthermore, a component mounting apparatus 100 according to one embodiment of the present disclosure includes the above-mentioned component supply device 30, a mounting head 107 (an example of a head) for holding the components supplied by the component supply device 30, an X-axis moving table 105 for moving the mounting head 107, a Y-axis moving table 106 (an example of a drive unit), and a substrate conveying mechanism 102 (an example of a substrate holding unit) for holding a substrate 103 on which the components held by the mounting head 107 are mounted.

[0171] This allows component mounting apparatus 100 to mount components onto substrate 103 that are suppressed from blackening.

[0172] (Other embodiments) While the component supply device and the like according to one or more aspects have been described above based on the embodiments, the present disclosure is not limited to these embodiments. As long as they do not deviate from the spirit of the present disclosure, various modifications conceivable by those skilled in the art to the present embodiments and configurations constructed by combining components of different embodiments may also be included in the present disclosure.

[0173] For example, in the above embodiment, the component supply device transports components by air, but the transport method is not limited to air. The component supply device may transport components by vibration instead of air, for example. Figure 11 is a block diagram showing the functional configuration of a component supply device 30a according to another embodiment.

[0174] 11, the component supply device 30a may include a first sensor 51, a second sensor 41, a control unit 61, a first vibration supply unit 62a, and a second vibration supply unit 63a. The first vibration supply unit 62a is a vibration generator for vibrating the conveyance unit 40, for example, vibrating the conveyance unit 40 along the X-axis direction. The second vibration supply unit 63a is a vibration generator for vibrating the supply unit 50, for example, vibrating the supply unit 50 along the X-axis direction. The control unit 61 controls the component transport by vibration in the conveyance unit 40 and the component transport by vibration in the supply unit 50 independently of each other.

[0175] In this case, the conveying unit 40 and the supplying unit 50 may be provided with a gap therebetween, for example. This makes it possible to prevent components from coming into contact with each other, compared to when the conveying unit 40 and the supplying unit 50 are vibrated integrally by a single vibration generating device. For example, the control unit 61 vibrates the conveying unit 40 only when there are no components in the supplying unit 50, thereby preventing components from coming into contact with each other when being conveyed by the conveying unit 40. Also, in this case, the first conveying portion 40a1 and the second conveying portion 40a2 of the conveying unit 40 may be provided with a gap therebetween, for example.

[0176] The component supply device 30a may transport components using both vibration and air. For example, the component supply device 30a may transport components using vibration in the transport unit 40 and air in the supply unit 50. When the transport unit 40 transports components using vibration, the first inclined surface and the second inclined surface do not need to be provided.

[0177] In the above embodiment, the shapes of the air ejection holes and suction holes are, for example, circular, but are not limited to this and may be any shape. The arrangement of the air ejection holes is not limited to that in the above embodiment.

[0178] Furthermore, in the above embodiment, an example has been described in which one suction hole is provided in the wall portion, but the present invention is not limited to this, and two or more suction holes may be provided.

[0179] In the above embodiment, the first sensor and the second sensor detect the presence or absence of parts as the quantity of parts, but this is not limited thereto and the sensor may detect the quantity of parts. The control unit may supply air to the conveying unit when the number of parts detected by the first sensor is equal to or less than a predetermined number. The control unit may also cause parts to be supplied from the case when the number of parts detected by the second sensor is equal to or less than a predetermined number. The quantity of parts is not limited to the number of parts and may be, for example, the weight of the parts. In this case, the first sensor and the second sensor are realized by sensors capable of detecting the weight of the parts.

[0180] Furthermore, the transport section and the supply section according to the above-described embodiment may be integrally formed, or may be formed separately and connected to each other.

[0181] In the above embodiment, the component supply device is described as being composed of a conveying unit and a supply unit, but may be further composed of a main body unit (e.g., main body unit 60). In other words, the component supply device may be realized by the feeder according to the above embodiment.

[0182] In the above embodiment, the component supply device is described as a device that conveys components supplied from a case that stores bulk components, but the present invention is not limited to this. For example, the component supply device may convey components supplied from a bowl having a spiral path on the inner wall along which the components can move. For example, the feeder may be a bowl feeder.

[0183] In the above embodiments, each component may be configured with dedicated hardware, or may be realized by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU or processor reading and executing a software program recorded on a recording medium such as a hard disk or semiconductor memory.

[0184] The order in which the steps in the flowchart are executed is merely an example for specifically explaining the present disclosure, and an order other than the above may be used. Also, some of the steps may be executed simultaneously (in parallel) with other steps, or some of the steps may not be executed.

[0185] The division of functional blocks in the block diagram is an example, and multiple functional blocks may be realized as a single functional block, one functional block may be divided into multiple blocks, or some functions may be moved to another functional block.Furthermore, the functions of multiple functional blocks having similar functions may be processed in parallel or time-shared by a single piece of hardware or software.

[0186] Furthermore, these general or specific aspects may be realized as a system, a method, an integrated circuit, a computer program, or a non-transitory recording medium such as a computer-readable CD-ROM, or may be realized as any combination of a system, a method, an integrated circuit, a computer program, or a recording medium.

[0187] Furthermore, each component described in the above embodiments may be implemented as software or, typically, as an LSI, an integrated circuit. These components may be integrated individually on a single chip, or some or all of them may be integrated on a single chip. While LSI is used here, it may also be referred to as an IC, system LSI, super LSI, or ultra LSI depending on the level of integration. Furthermore, the integration method is not limited to LSI; dedicated circuits or general-purpose processors may also be used. Field-programmable gate arrays (FPGAs), which can be programmed after LSI fabrication, or reconfigurable processors, which allow the reconfiguration of the connections or settings of circuit cells within an LSI, may also be used. Furthermore, if an integrated circuit technology that replaces LSI emerges due to advances in semiconductor technology or other derivative technologies, that technology may naturally be used to integrate the components.

[0188] A system LSI is an ultra-multifunctional LSI manufactured by integrating multiple processing units on a single chip, and is specifically a computer system consisting of a microprocessor, ROM (Read Only Memory), RAM (Random Access Memory), etc. Computer programs are stored in the ROM. The system LSI achieves its functions when the microprocessor operates in accordance with the computer program.

[0189] Furthermore, one aspect of the present disclosure may be a computer program that causes a computer to execute each of the characteristic steps included in the component supply method shown in any of FIGS. 8 to 9D.

[0190] Furthermore, for example, the program may be a program to be executed by a computer. Another aspect of the present disclosure may be a computer-readable non-transitory recording medium on which such a program is recorded. For example, such a program may be recorded on a recording medium and distributed or circulated. For example, the distributed program may be installed in a device having another processor, and the program may be executed by the processor, thereby causing the device to perform each of the above processes.
