[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. In each drawing, elements are exaggerated for ease of explanation.

[0011] As used herein, terms such as "first," "second," etc. are used for descriptive purposes only and should not be understood as expressing or implying the relative importance or ranking of technical features. Features qualified as "first" and "second" expressly or imply the inclusion of one or more of such features.

[0012] (Embodiment 1) 1 is a schematic perspective view of an example of a component mounting apparatus 100 according to a first embodiment of the present disclosure. Note that the X, Y, and Z directions in the figure indicate the depth, width, and height directions of the component mounting apparatus 100.

[0013] 1, component mounting apparatus 100 includes a plurality of component supply devices 1 and a component placement device 90. Component mounting apparatus 100 also includes a fixed base 80 that fixes and arranges the plurality of component supply devices 1 in a line. The plurality of component supply devices 1 are arranged in a line in the X direction on fixed base 80.

[0014] The component supply device 1 transports a plurality of components aligned in a row. The component supply device 1 also transports the aligned components to a plurality of component supply positions P1 and P2. In this embodiment, the component supply device 1 is described as an example that takes out components from a component storage unit 3 that stores a plurality of components loosely, and transports the taken-out components. Details of the component supply device 1 will be described later. In this specification, the plurality of component supply positions P1 and P2 may be referred to as a first component supply position P1 and a second component supply position P2.

[0015] The component mounting device 90 picks up a plurality of components conveyed to a plurality of component supply positions P1 and P2 and mounts them at predetermined positions.

[0016] The component mounting device 90 includes a head 91 and a plurality of nozzles 92 attached to the head 91 .

[0017] The head 91 is movable in the X, Y, and Z directions. For example, the head 91 is movable above a plurality of component supply devices 1 and above a board on which components are to be mounted.

[0018] The multiple nozzles 92 are devices capable of picking up and holding components. The multiple nozzles 92 pick up multiple components arranged at multiple component supply positions P1, P2 of the multiple component supply devices 1. The multiple nozzles 92 hold the picked-up multiple components and mount them at predetermined positions on the board.

[0019] The plurality of nozzles 92 are arranged at a predetermined pitch. For example, the plurality of nozzles 92 are arranged in two rows of four nozzles in the direction in which the plurality of component supply devices 1 are lined up (X direction).

[0020] The component supplying device 1 is attached to a component mounting device 100 that mounts the components 60 picked up by the nozzle 92 onto a board.

[0021] 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. 3 is a schematic front view of the example of the component supply device 1 according to the first embodiment of the present disclosure. Note that the X, Y, and Z directions in the figure indicate the widthwise, lengthwise, and heightwise directions of the component supply device 1.

[0022] 2 and 3, the component supply device 1 includes a main body 2, a component alignment unit 4, multiple component conveying paths 5A and 5B, an optical sensor 6, and an alarm lamp 7. The component supply device 1 also includes a conveying force loading unit 10 that loads a conveying force for conveying multiple components 60. The component alignment unit 4 supports the component storage unit 3. In this specification, the multiple component conveying paths 5A and 5B may be referred to as a first component conveying path 5A and a second component conveying path 5B.

[0023] The component supply device 1 aligns a plurality of components 60 stored in the component storage unit 3 using the component alignment unit 4, and transports the components 60 to a plurality of component supply positions P1, P2 on the upper surface of the main body 2 via a first component conveying path 5A and a second component conveying path 5B. The transportation of the components 60 in the first component conveying path 5A and the second component conveying path 5B is performed by applying a transport force using the transport force applying unit 10. In this embodiment, the transport force applying unit 10 transports the components 60 in the first component conveying path 5A and the second component conveying path 5B by introducing air.

[0024] Furthermore, the component supplying device 1 detects the presence or absence of components 60 in the first component conveying path 5A and the second component conveying path 5B using the optical sensor 6. For example, if the component supplying device 1 detects that there are no components 60 in the first component conveying path 5A or the second component conveying path 5B, the component supplying device 1 applies a conveying force to the multiple components 60 using the conveying force applying unit 10. Furthermore, if the component supplying device 1 detects that there are no components 60 in the first component conveying path 5A or the second component conveying path 5B while applying the conveying force, it turns on the notification lamp 7. This allows the user to be notified that there are no components 60 in the component storage unit 3.

[0025] Each of the components of the component supplying device 1 will now be described in detail.

[0026] <Main body> The main body 2 is the main body portion of the component supply device 1. A first component supply position P1 and a second component supply position P2 to which a plurality of components 60 are transported are provided on the upper surface of the main body 2. The first component supply position P1 and the second component supply position P2 are positions where openings are provided to expose the components 60 from the main body 2.

[0027] FIG. 4 is a schematic diagram showing an example of a plurality of component supply positions P1 and P2.

[0028] 4, a first component supply position P1 and a second component supply position P2 are provided at a distance from each other on the upper surface of the main body 2 of the component supply device 1. Specifically, the first component supply position P1 and the second component supply position P2 are provided side by side at a predetermined distance L1 in the longitudinal direction of the component supply device 1, i.e., in the longitudinal direction (Y direction) of the main body 2.

[0029] In this embodiment, the interval L1 is equal to the pitch of the nozzles 92 of the component mounting device 90.

[0030] 2 and 3, the main body 2 has, as the conveying force applying section 10, a mechanism for generating air for conveying a plurality of components 60. Specifically, the main body 2 has, as the conveying force applying section 10, an air introduction path 11, a conveying air supply path 12, a conveying air control valve 13, an air suction path 14, and a suction air control valve 15.

[0031] The air introduction path 11 introduces compressed air from an air introduction port 11a provided on the side surface at the rear end of the main body 2. The air introduction path 11 communicates with a transport air supply path 12 inside the main body 2. For example, the air introduction path 11 is formed by piping. A pump that supplies compressed air may be connected to the air introduction port 11a.

[0032] The conveying air supply path 12 is a flow path that supplies air to the first component conveying path 5A and the second component conveying path 5B. In this embodiment, the conveying air supply path 12 connects the main body 2 and the component alignment section 4. The air supplied from the conveying air supply path 12 passes through the component alignment section 4 and is supplied to the first component conveying path 5A and the second component conveying path 5B. The conveying air supply path 12 is formed of, for example, tubes and / or piping. A conveying air control valve 13 is arranged in the conveying air supply path 12.

[0033] The conveying air control valve 13 controls the air flowing through the conveying air supply path 12. Specifically, the conveying air control valve 13 controls the supply and stop of air from the conveying air supply path 12 to the first component conveying path 5A and the second component conveying path 5B. For example, when the conveying air control valve 13 opens, air is supplied to the first component conveying path 5A and the second component conveying path 5B through the conveying air supply path 12. When the conveying air control valve 13 closes, air is no longer supplied to the first component conveying path 5A and the second component conveying path 5B through the conveying air supply path 12.

[0034] The air suction path 14 is a flow path for sucking air. In the air suction path 14, air is sucked from an air suction port 14a provided on the side surface of the main body 2. The air suction path 14 extends from the air suction port 14a to the first component supply position P1 and the second component supply position P2. For example, the air suction path 14 is formed by a tube and / or a pipe. Furthermore, a pump for sucking air may be connected to the air suction port 14a.

[0035] The component supply device 1 can create a negative pressure by sucking air through the air suction path 14. This allows the component 60 to be sucked in, assisting in the transport of the component 60 to the first component supply position P1 and the second component supply position P2, and also allowing the component 60 to be held at the first component supply position P1 and the second component supply position P2.

[0036] A suction air control valve 15 is disposed in the air suction path 14 .

[0037] The suction air control valve 15 controls the air flowing through the air suction path 14. For example, when the suction air control valve 15 opens, air is sucked into the air suction path 14, creating a negative pressure. When the suction air control valve 15 closes, air is no longer sucked into the air suction path 14.

[0038] <Parts storage section> The component storage unit 3 stores a plurality of components 60. The component storage unit 3 is, for example, a box that stores a plurality of components 60. The component storage unit 3 is placed above the component alignment unit 4, and supplies a plurality of components 60 from the component storage unit 3 to the component alignment unit 4. The component storage unit 3 is detachably attached to the component supply device 1. The component storage unit 3 is provided with a component discharge port for discharging components to the outside.

[0039] The plurality of components 60 stored in the component storage section 3 are dropped into the component alignment section 4 by falling from the component drop opening due to their own weight.

[0040] <Parts Alignment Section> The component alignment unit 4 is a unit that aligns a plurality of components 60. In other words, the component alignment unit 4 is a mechanism for taking out the components 60 from the component storage unit 3 one by one.

[0041] FIG. 5 is a schematic cross-sectional view taken along line AA in FIG.

[0042] 5, the component alignment section 4 has a plurality of storage chambers 30 and a plurality of gates 31. The component alignment section 4 has the same number of storage chambers 30 and gates 31 as the number of component conveying paths 5A, 5B.

[0043] In the component alignment unit 4, a plurality of components 60 are fed from one component storage unit 3 into a plurality of storage chambers 30. The component alignment unit 4 supplies the components 60 fed into the plurality of storage chambers 30 to the first component conveying path 5A and the second component conveying path 5B from each of the plurality of gates 31. For example, the components 60 are fed by gravity from each of the plurality of gates 31 to the first component conveying path 5A and the second component conveying path 5B.

[0044] The component alignment unit 4 will be described in detail below.

[0045] The storage chamber 30 is formed by a through-hole that penetrates the component alignment unit 4 in the vertical direction. In this specification, the "vertical direction" refers to the vertical direction, or the Z direction. The storage chamber 30 is formed by a tapered through-hole whose diameter decreases toward the bottom of the component alignment unit 4. More specifically, the storage chamber 30 is formed by a through-hole in the shape of an inverted truncated cone.

[0046] The gate 31 aligns the multiple components 60 in a vertical line and discharges them onto the first component conveying path 5A or the second component conveying path 5B. The aperture diameter of the gate 31 is constant.

[0047] Gate 31 is formed as a through hole, and the diameter of the through hole is designed to allow multiple components 60 to pass through one by one. For example, if component 60 has a longitudinal direction and a lateral direction, the diameter of gate 31 is larger than the lateral dimension of component 60 and smaller than the longitudinal dimension.

[0048] The inner wall of the storage chamber 30 is formed as an inclined surface. The gate 31 is formed as a wall surface extending in the vertical direction.

[0049] In this manner, in this embodiment, components are taken out one by one from the plurality of components 60 placed in the storage chamber 30. In addition, the components 60 taken out from the storage chamber 30 are transported in a line by utilizing the air introduced into the first component transport path 5A and the second component transport path 5B.

[0050] <Multiple parts transport paths> The multiple component conveying paths 5A, 5B are paths that convey multiple components 60 from the component storage unit 3 to multiple component supply positions P1, P2. The multiple component conveying paths 5A, 5B include a first component conveying path 5A that conveys multiple components 60 from the component storage unit 3 to the first component supply position P1, and a second component conveying path 5B that conveys multiple components 60 from the component storage unit 3 to the second component supply position P2. The first component conveying path 5A conveys the components 60 to the first component supply position P1 where the multiple nozzles 92 can pick up the components 60. The second component conveying path 5B conveys the components 60 to the second component supply position P2, which is different from the first component supply position P1.

[0051] The first component conveying path 5A and the second component conveying path 5B are configured by, for example, tubes.

[0052] 6A and 6B are schematic diagrams showing a cross section of an example of the first component conveying path 5A.

[0053] 6A and 6B, the first component conveying path 5A is a tube having a through hole 8 formed therein. In a cross section of the first component conveying path 5A taken along a direction perpendicular to the component conveying direction, the through hole 8 has a circular or elliptical shape.

[0054] Incidentally, the smaller the components, the smaller their volume and weight, making them more likely to become stuck in the component conveying path. Therefore, the component conveying path requires high processing precision (for example, flatness precision). By configuring the first component conveying path 5A with a tube, it is possible to prevent multiple components 60 from becoming stuck in the first component conveying path 5A.

[0055] The first component conveying path 5A has, on at least a part of its inner surface, a conductive portion 50A and a light-transmitting portion 50B. The conductive portion 50A is grounded.

[0056] For example, if the first component conveying path 5A is made of a resin tube, friction occurs when the components 60 come into contact with the inner surface of the first component conveying path 5A. This friction can cause the components 60 to become charged, or the components 60 can become stuck inside the first component conveying path 5A due to static electricity.

[0057] By providing the conductive portion 50A on at least a part of the inner surface of the first component conveying path 5A, it is possible to suppress electrification and static electricity, and to prevent a plurality of components 60 from remaining inside the first component conveying path 5A.

[0058] The conductive portion 50A has a static electricity dissipation property that allows static electricity to be slowly discharged to a degree that does not damage the component 60. For example, the conductive portion 50A has a static electricity dissipation property that allows static electricity to be slowly discharged to a degree that does not damage the component 60. 4 Ω or more 10 9 The conductive portion 50A is made of a material having an electrical resistance of Ω or less. For example, the conductive portion 50A may be made of carbon.

[0059] The transmitting portion 50B is, for example, a portion made of a transparent material that can transmit light, or may be a window or a hole.

[0060] In this embodiment, the conductive portion 50A is provided on the entire first component conveying path 5A except for a part of the first component conveying path 5A. The transparent portion 50B is provided on a part of the first component conveying path 5A.

[0061] The configuration of the first component conveying path 5A will be described in detail later. The second component conveying path 5B has the same configuration as the first component conveying path 5A.

[0062] <Optical sensor> The optical sensor 6 detects whether or not there are components 60 in the multiple component conveying paths 5A, 5B. The optical sensor 6 may be, for example, a photoelectric sensor or a photosensor. In this embodiment, the component supply device 1 is equipped with two optical sensors 6 that detect the presence or absence of components 60 in the first component conveying path 5A and the second component conveying path 5B.

[0063] The optical sensor 6 is a sensor that uses light to detect the presence or absence of the component 60. The optical sensor 6 can be a transmission type or a reflection type sensor.

[0064] The optical sensor 6 is disposed midway between the first component conveying path 5A and the second component conveying path 5B. In this embodiment, the optical sensor 6 is provided at a connection part 20 provided midway between the first component conveying path 5A and the second component conveying path 5B. The configuration of the connection part 20 will be described later.

[0065] <Alarm lamp> The notification lamp 7 is a lamp provided on the side of the main body 2. For example, the notification lamp 7 lights up when a component runs out to notify the user.

[0066] Next, the main configuration for controlling the component mounting apparatus 100 will be described with reference to FIG.

[0067] FIG. 7 is a control block diagram of an example of the component mounting apparatus 100 according to the first embodiment of the present disclosure.

[0068] As shown in FIG. 7, the component mounting apparatus 100 includes a control unit 40 that controls the component supply device 1 and the component mounting device 90.

[0069] <Control unit> The control unit 40 can be realized by semiconductor elements or the like. The control unit 40 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 control unit 40 may be configured by hardware alone, or may be realized by combining hardware and software. The control unit 40 realizes predetermined functions by reading data and programs stored in a storage unit such as a memory and performing various arithmetic processing.

[0070] The control unit 40 may be provided in the component supplying device 1 or the component mounting device 90. Alternatively, the control unit 40 may be provided in a device separate from the component supplying device 1 and the component mounting device 90.

[0071] The control unit 40 may control the optical sensor 6, the notification lamp 7, the conveying air control valve 13, and the suction air control valve 15 in the component supply device 1. Specifically, the control unit 40 may control the notification lamp 7, the conveying air control valve 13, and the suction air control valve 15 based on the detection result of the optical sensor 6.

[0072] For example, when the control unit 40 detects by the optical sensor 6 that there are no components 60 on the first component conveying path 5A and the second component conveying path 5B, it may open the conveying air control valve 13 and use air to convey the components 60 in the first component conveying path 5A and the second component conveying path 5B toward the first component supply position P1 and the second component supply position P2.

[0073] Furthermore, when the optical sensor 6 detects that there are no components 60 on the first component conveying path 5A or the second component conveying path 5B for a predetermined period of time while the conveying air control valve 13 is open, the control unit 40 may close the conveying air control valve 13 and the suction air control valve 15 and turn on the notification lamp 7. This allows the user to be notified that there is a shortage of components.

[0074] The control unit 40 also controls a head 91 including a plurality of nozzles 92 in the component mounting device 90 .

[0075] For example, the control unit 40 may control the head 91 to simultaneously pick up a component 60 located at a first component supply position P1 and a component 60 located at a second component supply position P2 in the component supply device 1. Here, if the pitch of the multiple nozzles 92 provided on the head 91 is equal to the distance between the first component supply position P1 and the second component supply position P2, the multiple components 60 located at the first component supply position P1 and the second component supply position P2 can be easily picked up. Here, "simultaneous pickup" means that the multiple nozzles 92 are lowered to hold the multiple components 60 with the multiple nozzles 92. The head 91 may hold the multiple components 60 one by one with multiple holding operations (up and down movements of the nozzles 92), or may hold the multiple components 60 by simultaneously lowering the multiple nozzles 92. The head 91 then mounts the multiple components 60 held in this manner on a board.

[0076] For example, the control unit 40 may control the head 91 to alternately pick up the component 60 located at the first component supply position P1 and the component 60 located at the second component supply position P2 in the component supply device 1. Here, alternately picking up means that one of the multiple nozzles 92 holds a component 60 from either the first component supply position P1 or the second component supply position P2, and after the multiple components 60 held by the multiple nozzles 92 of the head 91 are mounted on a board, one of the multiple nozzles 92 of the head 91 holds a component 60 from the other of the first component supply position P1 or the second component supply position P2.

[0077] For example, the control unit 40 may select at least one of the components 60 located at the first component supply position P1 and the components 60 located at the second component supply position P2 based on the detection result of the optical sensor 6, and control the head 91 to pick up at least one of the selected components 60. For example, if the control unit 40 does not detect a component 60 in the first component conveying path 5A but detects a component 60 in the second component conveying path 5B, the control unit 40 may control the head 91 to select and pick up the component 60 located at the second component supply position P2.

[0078] Next, the detailed configurations of the first component conveying path 5A, the optical sensor 6, and the connecting portion 20 will be described with reference to FIGS.

[0079] Fig. 8 is a schematic diagram of an example of the connection portion 20. Fig. 9 is a schematic cross-sectional view taken along line AA in Fig. 8. Fig. 10 is a schematic partially enlarged cross-sectional view of part Z1 in Fig. 9. Fig. 11 is a schematic partially enlarged cross-sectional view of part Z2 in Fig. 9.

[0080] 8 and 9, the first component conveying path 5A includes a first conveying path 51, a second conveying path 52, and a third conveying path 53. The connecting unit 20 has a mechanism for connecting the first conveying path 51, the second conveying path 52, and the third conveying path 53, and a mechanism for detecting the presence or absence of components 60 in the second conveying path 52 by an optical sensor 6.

[0081] A conductive portion 50A is provided on at least a portion of the inner surface of the first transport path 51 and the third transport path 53. In this embodiment, the first transport path 51 and the third transport path 53 are tubes, and at least the entire inner surface of the first transport path 51 and the third transport path 53 is made up of the conductive portion 50A. The conductive portion 50A is a member that does not transmit light, and the first transport path 51 and the third transport path 53 do not transmit light.

[0082] The second transport path 52 is provided with a transmission section 50B at least partially capable of transmitting light from the optical sensor 6. In this embodiment, the entire second transport path 52 is made up of the transmission section 50B. Specifically, the second transport path 52 is a transparent tube. The second transport path 52 has one end located on the upstream side and the other end located on the downstream side.

[0083] In this specification, the first conveying path 51, the second conveying path 52, and the third conveying path 53 may be referred to as the first tube 51, the second tube 52, and the third tube 53.

[0084] The first conveying path 51 is disposed upstream of the second conveying path 52 in the conveying direction of the multiple components 60, and is connected to one end of the second conveying path 52. The third conveying path 53 is disposed downstream of the second conveying path 52 in the conveying direction of the multiple components 60, and is connected to the other end of the second conveying path 52.

[0085] Through holes 8A, 8B, and 8C are provided inside the first transport path 51, the second transport path 52, and the third transport path 53, respectively. The first transport path 51, the second transport path 52, and the third transport path 53 are arranged so that the through holes 8A, 8B, and 8C communicate with each other in the transport direction. The through holes 8A, 8B, and 8C each have a circular cross section.

[0086] The first conveying path 51, the second conveying path 52, and the third conveying path 53 are fixed in a connected state by a connecting portion 20.

[0087] As described above, in the first component conveying path 5A, the first conveying path 51 and the third conveying path 53 are provided with conductive portions 50A, and the second conveying path 52 is provided with a transparent portion 50B through which the detection light of the optical sensor 6 can pass. This allows the optical sensor 6 to detect the components 60 while suppressing the buildup of static electricity and electrification due to friction that occurs when multiple components 60 move along the first component conveying path 5A. Generally, conductive members are often made of materials that do not transmit light, so providing the conductive portion 50A makes it difficult to detect the components 60 using sensors such as capacitance sensors or ultrasonic sensors. In the component supplying device 1, the second conveying path 52 that detects the components 60 is provided with a transparent portion 50B through which the detection light of the optical sensor 6 can pass, thereby enabling the optical sensor 6 to detect the components 60.

[0088] The connection portion 20 includes a first holder 21, a second holder 22, a third holder 23, and a fixing portion 24.

[0089] The first holder 21 holds the second transport path 52 therein. For example, the first holder 21 is provided with a holding hole 21A that holds the second transport path 52. The holding hole 21A of the first holder 21 is in communication with the second transport path 52 in the transport direction. The length of the holding hole 21A of the first holder 21 in the transport direction is greater than the length of the second transport path 52.

[0090] The first holder 21 has a first end E1 on the upstream side in the conveying direction and a second end E2 on the downstream side in the conveying direction. In this embodiment, the first end E1 is the bottom surface of a recess provided in the side surface of the first holder 21 on the upstream side in the conveying direction. The second end E2 is the bottom surface of a recess provided in the side surface of the first holder 21 on the downstream side in the conveying direction.

[0091] The first holder 21 is also provided with a light guide path 25 that guides the detection light of the optical sensor 6. The light guide path 25 guides the detection light of the optical sensor 6 to the transmission section 50B of the second transport path 52. The light guide path 25 extends in a direction intersecting the second transport path 52, i.e., in a direction intersecting the transport direction. The light guide path 25 is, for example, a through hole.

[0092] In this embodiment, the optical sensor 6 is a transmissive optical sensor. The optical sensor 6 includes a light-emitting unit 6A and a light-receiving unit 6B. The light-emitting unit 6A emits detection light. The light-receiving unit 6B receives the detection light emitted from the light-emitting unit 6A.

[0093] The detection light emitted from the light-emitting unit 6A travels through the light guide path 25 toward the light-receiving unit 6B. The transmission unit 50B of the second transport path 52 is provided midway along the light guide path 25. If a component 60 is present in the transmission unit 50B within the second transport path 52, the detection light is blocked by the component 60. As a result, the light-receiving unit 6B does not receive the detection light, or receives it with difficulty. In this case, the control unit 40 can determine that a component 60 is present within the second transport path 52. On the other hand, if a component 60 is not present in the transmission unit 50B within the second transport path 52, the detection light is incident on the light-receiving unit 6B without being blocked by the component 60. In this case, the control unit 40 can determine that a component 60 is not present within the second transport path 52.

[0094] The second holder 22 is connected to the first end E1 of the first holder 21 upstream of the second transport path 52 in the transport direction, and holds the first transport path 51 connected to the second transport path 52. For example, the second holder 22 is provided with a holding hole 22A that holds the first transport path 51. The holding hole 22A of the second holder 22 is connected along the transport direction. A portion of the downstream side of the first transport path 51 in the transport direction protrudes from the holding hole 22A of the second holder 22, and is arranged in the holding hole 21A of the first holder 21.

[0095] The third holder 23 is connected to the second end E2 of the first holder 21 downstream of the second transport path 52 in the transport direction, and holds the third transport path 53 in a connected state to the second transport path 52. For example, the third holder 23 is provided with a holding hole 23A that holds the third transport path 53. The holding hole 23A of the third holder 23 is connected along the transport direction. A portion of the upstream side of the third transport path 53 in the transport direction protrudes from the holding hole 23A of the third holder 23, and is arranged in the holding hole 21A of the first holder 21.

[0096] The second holder 22 and the third holder 23 may use, for example, tube flanges. For example, the second holder 22 and the third holder 23 may be integrated with the first conveying path 51 and the third conveying path 53, respectively. The second holder 22 and the third holder 23 may be bonded to the first conveying path 51 and the third conveying path 53, respectively, with an adhesive or the like. Alternatively, the first conveying path 51 and the third conveying path 53 may be press-fitted into the holding holes 22A and 23A of the second holder 22 and the third holder 23, respectively.

[0097] The fixing unit 24 presses the second holder 22 against the first end E1 of the first holder 21 and the third holder 23 against the second end E2 of the first holder 21, thereby fixing the second holder 22 and the third holder 23 to the first holder 21. The fixing unit 24 fixes both ends of the second conveying path 52 in close contact with the first conveying path 51 and the third conveying path 53, respectively. The fixing unit 24 is, for example, a clamp. With this configuration, the first conveying path 51, the second conveying path 52, and the third conveying path 53, which form the air flow path, are fixed in close contact with each other, preventing air from leaking from the joints of the component conveying path 5A. When components 60 are conveyed by air, the air pressure within the component conveying path 5A affects the conveying speed of the components 60. The fixing portion 24 prevents air from leaking from the component conveying path 5A, and when compressed air is supplied to the component conveying path 5A, the air pressure in the component conveying path 5A can be maintained within a predetermined range. Therefore, the component 60 can be conveyed toward the component supply positions P1 and P2 at a desired speed.

[0098] 10, the opening of through hole 8B of second transport path 52 on the upstream side in the transport direction is larger than the opening of through hole 8A of first transport path 51 on the downstream side in the transport direction. In other words, the dimension D20 of the opening of through hole 8B of second transport path 52 on the upstream side in the transport direction is larger than the dimension D10 of the opening of through hole 8A of first transport path 51 on the downstream side in the transport direction. In this embodiment, since the through holes 8A and 8B have a circular cross section, the dimensions D10 and D20 are diameters.

[0099] A portion of the through hole 8B of the second transport path 52 on the upstream side in the transport direction is tapered. Specifically, in the second transport path 52, the dimension of the through hole 8B continuously decreases from the opening of the through hole 8B on the upstream side in the transport direction toward the downstream. Furthermore, the dimension D21 of the through hole 8B is constant from the middle of the second transport path 52 toward the downstream.

[0100] In this way, in the portion where the first conveying path 51 and the second conveying path 52 are connected, the opening of the through hole 8B of the second conveying path 52 is made larger than the opening of the through hole 8A of the first conveying path 51. This allows the components 60 to be transported smoothly in this portion.

[0101] 11, the opening of through-hole 8C of third conveying path 53 on the upstream side in the conveying direction is larger than the opening of through-hole 8B of second conveying path 52 on the downstream side in the conveying direction. That is, dimension D21 of the opening of through-hole 8C of third conveying path 53 on the upstream side in the conveying direction is larger than dimension D30 of the opening of through-hole 8B of second conveying path 52 on the downstream side in the conveying direction. In this embodiment, since through-holes 8A and 8B have a circular cross section, dimensions D21 and D30 are diameters. Furthermore, dimension D21 is smaller than dimension D20.

[0102] A portion of the through hole 8C of the third transport path 53 on the upstream side in the transport direction is tapered. Specifically, in the third transport path 53, the dimension of the through hole 8C continuously decreases from the opening of the through hole 8C on the upstream side in the transport direction toward the downstream. Furthermore, the dimension D31 of the through hole 8C is constant from the middle of the third transport path 53 toward the downstream.

[0103] In this way, in the portion where the second conveying path 52 and the third conveying path 53 are connected, the opening of the through hole 8C of the third conveying path 53 is made larger than the opening of the through hole 8B of the second conveying path 52. This allows the components 60 to be transported smoothly in this portion.

[0104] According to the component supply device 1 of the first embodiment of the present disclosure, the following effects can be achieved.

[0105] The component supply device 1 includes component conveying paths 5A, 5B that convey multiple components 60 to component supply positions P1, P2, and an optical sensor 6 that uses light to detect the presence or absence of components 60 in the component conveying paths 5A, 5B. The component conveying paths 5A, 5B include a conductive portion 50A provided on at least a portion of the inner surface and a transparent portion 50B that is capable of transmitting light. The optical sensor 6 detects the presence or absence of components 60 in the component conveying paths 5A, 5B at the transparent portion 50B.

[0106] With this configuration, the components 60 on the component conveying paths 5A, 5B having the conductive portion 50A can be detected. In addition, the conductive portion 50A can slowly discharge electrified and / or static electricity, preventing the components 60 from remaining on the component conveying paths 5A, 5B.

[0107] The component transport paths 5A and 5B are configured from a first transport path 51 provided with a conductive portion 50A, and a second transport path 52 connected to the first transport path 51 and provided with a transparent portion 50B.

[0108] With this configuration, the components 60 in the component conveying paths 5A and 5B can be detected with a simple configuration.

[0109] A conductive portion 50A is provided on at least the entire inner surface of the first transport path 51, and the second transport path 52 is made of a transparent material.

[0110] With this configuration, it is possible to detect the components 60 in the component conveying paths 5A and 5B while further preventing the components 60 from remaining on the component conveying paths 5A and 5B.

[0111] The component conveying paths 5A and 5B are tubes with through holes 8 formed therein.

[0112] With this configuration, it is possible to detect the components 60 in the component conveying paths 5A and 5B while further preventing the components 60 from remaining on the component conveying paths 5A and 5B.

[0113] The component conveying paths 5A and 5B include a third conveying path 53 that is connected to the second conveying path 52 and has a conductive portion 50A on at least a part of its inner surface. The first conveying path 51 is located upstream of the second conveying path 52 in the conveying direction of the multiple components 60, and the third conveying path 53 is located downstream of the second conveying path 52 in the conveying direction.

[0114] With this configuration, the components 60 in the component conveying paths 5A and 5B can be easily detected.

[0115] The opening of through-hole 8B of second transport path 52 on the upstream side in the transport direction is larger than the opening of through-hole 8A of first transport path 51 on the downstream side in the transport direction. The opening of through-hole 8C of third transport path 53 on the upstream side in the transport direction is larger than the opening of through-hole 8B of second transport path 52 on the downstream side in the transport direction.

[0116] This configuration prevents components from getting caught, allowing multiple components 60 to move smoothly within component conveying paths 5A and 5B.

[0117] In each of the second transport path 52 and the third transport path 53, the through holes 8B and 8C on the upstream side in the transport direction are tapered.

[0118] With this configuration, even if there is variation in the dimensions of the components, the multiple components 60 can move more smoothly within the component conveying paths 5A and 5B.

[0119] The component supply device 1 includes a connection unit 20 that connects a first conveying path 51, a second conveying path 52, and a third conveying path 53. The connection unit 20 includes a first holder 21, a second holder 22, and a third holder 23. The first holder 21 has a first end E1 on the upstream side in the conveying direction and a second end E2 on the downstream side in the conveying direction, and holds the second conveying path therein. The second holder 22 is connected to the first end E1 of the first holder 21 upstream of the second conveying path 52 in the conveying direction, and holds the first conveying path 51 connected to the second conveying path 52. The third holder 23 is connected to the second end E2 of the first holder 21 downstream of the second conveying path 52 in the conveying direction, and holds the third conveying path 53 connected to the second conveying path 52. The first holder 21 has a light guide path 25 that guides the light from the optical sensor 6 to the transmission section 50B in the second transport path 52.

[0120] With this configuration, the first transport path 51, the second transport path 52, and the third transport path 53 can be connected in close contact with each other.

[0121] The first holder 21 has a holding hole 21A that holds the second transport path 52. The length of the holding hole 21A in the transport direction is greater than that of the second transport path 52. A downstream portion of the first transport path 51 in the transport direction is disposed within the holding hole 21A of the first holder 21. An upstream portion of the third transport path 53 in the transport direction is disposed within the holding hole 21A of the first holder 21.

[0122] With this configuration, the first transport path 51, the second transport path 52, and the third transport path 53 can be more easily connected in close contact with each other.

[0123] The connection portion 20 includes a fixing portion 24 that fixes the second holder 22 and the third holder 23 to the first holder 21 by pressing the second holder 22 against the first end E1 of the first holder 21 and pressing the third holder 23 against the second end E2 of the first holder 21.

[0124] With this configuration, the first conveying path 51, the second conveying path 52 and the third conveying path 53 can be tightly attached to each other, and can be fixed while preventing air from leaking from the component conveying paths 5A and 5B.

[0125] The component conveying paths 5A, 5B in the first embodiment of the present disclosure are tubes having through holes 8 for conveying a plurality of components 60, and each of the tubes has a conductive portion 50A provided on at least a portion of its inner surface and a light-transmitting portion 50B that can transmit light. This provides the same effects as the component supply device 1 described above. Furthermore, the tubes can convey the components 60 more smoothly than component conveying paths such as grooves.

[0126] (Other embodiments) In the present embodiment, an example has been described in which the component supply device 1 includes the optical sensor 6 and the notification lamp 7, but the present invention is not limited to this. The optical sensor 6 and the notification lamp 7 are not essential components.

[0127] In the present embodiment, an example has been described in which the multiple component supply positions P1, P2 include two component supply positions P1, P2, but this is not limiting. The multiple component supply positions P1, P2 may include two or more component supply positions.

[0128] In the present embodiment, an example has been described in which the multiple component conveying paths 5A, 5B include two component conveying paths 5A, 5B, but the present invention is not limited to this. The multiple component conveying paths 5A, 5B may include one or more component conveying paths.

[0129] FIG. 12 is a schematic diagram showing another example of the component supply device 1. In FIG.

[0130] 12, the component supply device 1 may be provided with four component supply positions P1 to P4 and four component conveying paths 5A to 5D. For example, the first to fourth component conveying paths 5A to 5D are supplied with a plurality of components 60 from the component storage unit 3. The first to fourth component conveying paths 5A to 5D may convey a plurality of components 60 to the first to fourth component supply positions P1 to P4, respectively.

[0131] The third component supply position P3 and the fourth component supply position P4 may be arranged side by side at a predetermined interval L1 in the longitudinal direction (Y direction) of the component supply device 1. The first component supply position P1 and the third component supply position P3 may be arranged side by side at a predetermined interval L2 in the lateral direction (X direction) intersecting the longitudinal direction (Y direction) of the component supply device 1. The second component supply position P2 and the fourth component supply position P4 may be arranged side by side at a predetermined interval L2 in the lateral direction (X direction) intersecting the longitudinal direction (Y direction) of the component supply device 1. The intervals L1 and L2 may be equal to the pitch of the multiple nozzles 92 of the head 91.

[0132] In the example shown in FIG. 12, the component alignment section 4 may have four storage chambers 30 and four gates 31.

[0133] With this configuration, the speed at which the multiple components 60 are supplied can be further improved.

[0134] In the present embodiment, the second component conveying path 5B has been described as having the same configuration as the first component conveying path 5A, but is not limited to this. For example, the second component conveying path 5B may have a different configuration from the first component conveying path 5A.

[0135] In the present embodiment, an example has been described in which the multiple component conveying paths 5A, 5B are configured as tubes, but the present invention is not limited to this. For example, the multiple component conveying paths 5A, 5B may be configured as pipes, grooves, sticks, or the like.

[0136] In the present embodiment, an example has been described in which the first transport path 51 and the third transport path 53 do not transmit light, but the present invention is not limited to this. For example, the first transport path 51 and the third transport path 53 may be made of a material that transmits light. In this case, the first transport path 51, the second transport path 52, and the third transport path 53 may be integrally formed.

[0137] In the present embodiment, an example has been described in which the entire second transport path 52 is configured by the light-transmitting portion 50B, but the present invention is not limited to this. For example, it is sufficient that the light-transmitting portion 50B is provided in at least a part of the second transport path 52.

[0138] FIG. 13 is a schematic cross-sectional view showing another example of the first component conveying path 5A.

[0139] 13, the second transport path 52 may be provided with a transmissive section 50B at a portion where it intersects with the light guide path 25. In the second transport path 52, portions other than the transmissive section 50B may not transmit light. Furthermore, conductive sections 50A may be provided in portions other than the transmissive section 50B. The transmissive section 50B may be, for example, a transparent window or a hole.

[0140] In this embodiment, an example has been described in which a portion of the through hole 8B of the second conveying path 52 on the upstream side of the conveying direction is tapered, and the dimension D21 of the through hole 8B is constant from the middle of the second conveying path 52 toward the downstream, but this is not limited to this.

[0141] In this embodiment, an example has been described in which a portion of the through hole 8C of the third conveying path 53 on the upstream side of the conveying direction is formed tapered, and the dimension D31 of the through hole 8C is constant from the middle of the third conveying path 53 toward the downstream, but this is not limited to this.

[0142] FIG. 14 is a schematic partial enlarged view showing another example of the first component conveying path 5A.

[0143] 14, the through holes 8A of the first transport path 51, the through holes 8B of the second transport path 52, and the through holes 8C of the third transport path 53 may each have a tapered shape in which the hole diameter continuously and gradually decreases from upstream to downstream in the transport direction. In other words, the through holes 8A of the first transport path 51, the through holes 8B of the second transport path 52, and the through holes 8C of the third transport path 53 may not have a portion with a constant hole diameter.

[0144] Even in this configuration, the plurality of components 60 can move smoothly at the connection portion between the first conveying path 51, the second conveying path 52, and the third conveying path 53.

[0145] In the present embodiment, an example has been described in which the conveying force applying unit 10 has a mechanism for introducing air, but the present invention is not limited to this. For example, the conveying force applying unit 10 may have a mechanism for conveying multiple components 60 by force such as vibration, electromagnetic force, a belt conveyor, or gravity.

[0146] For example, the configuration of the multiple component conveying paths 5A, 5B of the component supply device 1 may be applied to a bowl feeder or a stick feeder.

[0147] When applied to a bowl feeder, the plurality of component conveying paths 5A, 5B may be formed as grooves, and the transparent portion 50B of the second conveying path 52 may be a hole.

[0148] When applied to a stick feeder, the component storage unit 3 may use a stick case. A single stick case may branch into multiple component conveying paths 5A, 5B to supply multiple components 60 to multiple component supply positions P1, P2. In this case, the stick itself may be multiple component conveying paths 5A, 5B.

[0149] For example, the component storage unit 3 may be configured to have an inlet through which the components 60 are introduced. In other words, the configuration of the component conveying path 5A is also applicable to the "hopper type" feeder described in Japanese Utility Model Laid-Open Publication No. 4-125238. For example, the component storage unit 3 may be configured to have a hopper that stores a plurality of components 60 and that can move back and forth up and down, a component introduction path that has an inlet at its bottom end through which the components 60 supplied from the hopper are introduced into the component conveying paths 5A and 5B, and a stopper that stops the components 60 placed at the inlet. The stopper may release the stop on the components 60 by lowering the hopper, allowing the components 60 to be introduced into the component conveying paths 5A and 5B.

[0150] In the present embodiment, an example has been described in which the first component conveying path 5A is configured with the first conveying path 51, the second conveying path 52, and the third conveying path 53, but the present invention is not limited to this. For example, the first component conveying path 5A does not need to include the third conveying path 53. For example, the first component conveying path 5A may have a conductive portion 50A provided on at least a part of its inner surface and a transmissive portion 50B that is capable of transmitting light. For example, the first component conveying path 5A may be a single tube in which at least the inner surface is configured with the conductive portion 50A, excluding the transmissive portion 50B.

[0151] In the present embodiment, an example has been described in which the component supply device 1 includes the connection unit 20, but the present invention is not limited to this. For example, the connection unit 20 is not an essential component.

[0152] In the present embodiment, an example has been described in which parts of the first transport path 51 and the third transport path 53 protrude from the second holder 22 and the third holder 23 and are disposed within the holding holes 21A of the first holder 21, but this is not limiting. For example, both end portions of the second transport path 52 may protrude from the first holder 21 and be disposed within the holding holes 22A, 23A of the second holder 22 and the third holder 23.

[0153] In this embodiment, the component alignment unit 4 is described as being composed of the storage chamber 30 and the gate 31, but is not limited thereto. The component alignment unit 4 may include a movable part that can move up and down or rotate, and the gate 31 may be provided on the movable part. This prevents components 60 from clogging the portion of the gate 31 that connects to the storage chamber 30. The component alignment unit 4 may also be configured to intermittently blow air into the portion of the gate 31 that connects to the storage chamber 30. In this case, the control unit 40 may control the movement of the movable part and the blowing of air based on the detection result of the optical sensor 6.

[0154] In the present embodiment, an example has been described in which the conveying air control valve 13 and the suction air control valve 15 are provided in the main body 2, but this is not limiting. For example, the conveying air control valve 13 and the suction air control valve 15 do not have to be provided in the main body 2.

[0155] Although the present invention has been described above using the above-mentioned embodiments, the present disclosure is not limited to the above-mentioned embodiments, and the technology in the present disclosure is also applicable to embodiments in which modifications, substitutions, additions, omissions, etc. are made as appropriate.

[0156] Although the present disclosure has been fully described in connection with the preferred embodiments with reference to the accompanying drawings, various changes and modifications will be apparent to those skilled in the art, and such changes and modifications are to be understood as being included within the scope of the present disclosure as defined by the appended claims unless they depart therefrom.

[0157] Furthermore, the general and specific aspects of the present disclosure may be realized by a system, a method, a computer program, a computer-readable storage medium, and combinations thereof.
