[0011] (Background to this disclosure) Before describing the embodiments of the present disclosure, the background to the present disclosure will be described.

[0012] As described in the "Background Art" section, in Patent Document 1, information in the recording section of each feeder is read by a reader device using multiple antennas arranged in correspondence with the recording section (tag) of each of the multiple feeders.

[0013] However, since a large number of feeders are attached to the component supply unit, the following problems arise when reading information from the feeder tags using a structure such as that of Patent Document 1.

[0014] (i) A reader device connected to multiple antennas requires multiple connection terminals (input ports), which results in complex wiring between the antennas and the reader device and a large reader device, requiring a large amount of space for installation.

[0015] (ii) In view of the problem in (i) above, if a configuration is adopted in which multiple antennas are connected and the reader device is connected to a number of relay points that is fewer than the number of antennas, control of reading by the reader device becomes complicated.

[0016] (iii) In a configuration in which a plurality of reader devices are arranged corresponding to a plurality of antennas, the large number of reader devices poses a problem in terms of cost.

[0017] As described above, the conventional technology has room for improvement in terms of simplifying the wiring between the antenna and the reader device and reducing the space required for arranging the reader device.

[0018] Therefore, the present disclosure provides an implementation system etc., which uses an antenna configured to be capable of communicating with RFID (Radio Frequency Identification) tags provided on multiple component containers or feeders to be managed, and which identifies the position of each of the multiple component containers or feeders in a placement section (described later) using a number of antennas fewer than the number of component containers or feeders.

[0019] A mounting system according to a first aspect of the present disclosure comprises a placement section capable of arranging at least one of a component container that stores components and a feeder to which the component container is attached in a predetermined direction, one or more antennas configured to communicate with tags provided on a plurality of objects including a plurality of the feeders arranged in the placement section or a plurality of the component containers arranged in the placement section, and a first processing section that identifies positions of the plurality of objects in the predetermined direction based on radio waves received by the one or more antennas from the tags of each of the plurality of objects, wherein the number of the one or more antennas is less than the number of the objects that can be arranged in the placement section.

[0020] As a result, since the number of the one or more antennas is smaller than the number of objects that can be placed on the placement section, the number of connection terminals of a device (e.g., an RFID reader) connected to the one or more antennas can be reduced, and the number of wires connecting the one or more antennas to the device can be reduced, compared to when the number of the one or more antennas is the same as the number of objects that can be placed. Therefore, according to the mounting system, the device can be made smaller and the wiring space can be reduced, so that the components for reading tag information can be made more space-saving.

[0021] Also, for example, an implementation system according to a second aspect of the present disclosure may be an implementation system according to the first aspect, wherein the first processing unit uses as input information information based on a first received signal strength indicating the signal strength of radio waves received by each of the one or more antennas from the tags of each of the multiple objects, and identifies the position of the object in the specified direction using a first learning model learned using information regarding the position of the object on which the tag is provided in the specified direction as correct answer data.

[0022] This allows the position of each of the multiple objects in the arrangement section to be identified, and production can be carried out using this position information, thereby supporting appropriate production.

[0023] Also, for example, an implementation system according to a third aspect of the present disclosure may be an implementation system according to the second aspect, and the first processing unit may identify the position of the object in the specified direction using the first learning model that differs depending on the type of the placement unit.

[0024] This makes it possible to more accurately identify the positions of each of the multiple objects in the placement section even if the type of placement section changes.

[0025] Also, for example, a mounting system according to a fourth aspect of the present disclosure is a mounting system according to the second or third aspect, wherein the target object is the component container, the second learning model is learned using as input information information based on a second received signal strength indicating a signal strength of a radio wave received when the quantity of components contained in the component container is a different quantity from when the radio wave of the first received signal strength is received, and the first processing unit may switch between the first learning model and the second learning model depending on the quantity of components contained in the component container attached to two or more of the feeders arranged in the placement unit.

[0026] This makes it possible to accurately identify the positions of the multiple objects in the placement section, regardless of the number of components contained in the component container.

[0027] Furthermore, for example, an implementation system according to a fifth aspect of the present disclosure is an implementation system according to any one of the second to fourth aspects, wherein the third learning model is learned as input information based on a third received signal strength indicating the signal strength of radio waves received when at least one of the number and positions of the multiple objects arranged in the placement section is different from the number and position when the radio waves of the first received signal strength were received, and the first processing unit may switch between the first learning model and the third learning model depending on at least one of the number and positions of the objects arranged in the placement section.

[0028] This makes it possible to accurately identify the position of each of the multiple objects in the arrangement section, regardless of at least one of the number and positions of the multiple objects arranged in the arrangement section.

[0029] Furthermore, for example, an implementation system according to a sixth aspect of the present disclosure is an implementation system according to any one of the second to fifth aspects, wherein the target object is arranged in the placement section via the feeder, and a fourth learning model is learned using as input information information based on a fourth received signal strength indicating the signal strength of radio waves received when at least one of the number and positions of the feeders arranged in the placement section is at least one of the number and positions different from when the first received signal strength was received, and the first processing unit may switch between the first learning model and the fourth learning model depending on at least one of the number and positions of the feeders arranged in the placement section.

[0030] This makes it possible to accurately identify the positions of the multiple component receptacles in the placement section, regardless of at least one of the number and positions of the feeders arranged in the placement section.

[0031] Also, for example, a mounting system according to a seventh aspect of the present disclosure may be a mounting system according to any of the first to sixth aspects, wherein the placement section is capable of placing a plurality of first component holders and a plurality of second component holders side by side, and places the first component holders and the second component holders such that a first tag provided on the first component holder and a second tag provided on the second component holder are placed at different positions in the vertical direction, and the first processing section identifies positions of the first component holders and the second component holders placed in the placement section based on radio waves received by the one or more antennas from each of the first tag and the second tag.

[0032] This makes it possible to identify the position in a predetermined direction of each of the component containers arranged at different positions in the vertical direction by radio waves from the component containers arranged at different positions in the vertical direction.

[0033] Also, for example, a mounting system according to an eighth aspect of the present disclosure may be the mounting system according to the seventh aspect, wherein the placement section includes a feeder support section capable of arranging a plurality of the first component holders in the predetermined direction via the feeder, and a first tape cassette support section capable of arranging a plurality of the second component holders in the predetermined direction below the feeder support section.

[0034] This makes it possible to reduce the space required for components for reading tag information in a mounting system that includes a placement unit that includes a feeder designation unit and a first tape cassette designation unit.

[0035] Also, for example, a mounting system according to a ninth aspect of the present disclosure may be the mounting system according to the seventh aspect, wherein the first tag is provided on a first side surface of the first component holder and the second tag is provided on a second side surface of the second component holder, and the arrangement section is capable of arranging the first component holder and the second component holder side by side in the predetermined direction, and is configured to be able to arrange the first component holder and the second component holder such that the vertical positions of the first side surface and the second side surface are different.

[0036] This makes it possible to identify the position of each of the component containers arranged so that the tags are positioned differently in the vertical direction.

[0037] Also, for example, a mounting system according to a tenth aspect of the present disclosure may be a mounting system according to any one of the fifth to ninth aspects, wherein the placement section has a first placement section capable of placing a plurality of the first component holders and a second placement section capable of placing a plurality of the second component holders, the one or more antennas include one or more first antennas provided in the first placement section and one or more second antennas provided in the second placement section, the number of the one or more first antennas being less than the number of the first component holders that can be placed in the first placement section, and the number of the one or more second antennas being less than the number of the second component holders that can be placed in the second placement section.

[0038] This means that when radio waves from the tags of the component containers placed above and below the feeder are received using different antennas, the number of antennas can be reduced, resulting in more effective space savings.

[0039] Furthermore, for example, a mounting system according to an eleventh aspect of the present disclosure may be a mounting system according to any one of the first to tenth aspects, in which the arrangement section is provided on a cart section that holds a plurality of the feeders together and can be mounted at a predetermined position on the device main body, and the one or more antennas are provided on the cart section.

[0040] This makes it possible to reduce the space required for components for reading tag information in the trolley section.

[0041] Also, for example, a mounting system according to a twelfth aspect of the present disclosure is a mounting system according to any one of the first to tenth aspects, further comprising a supply device that supplies at least one of the feeder and the component container to the mounting device, and the placement section and the one or more antennas may be provided on the supply device.

[0042] This allows the space required for components in the supply device for reading tag information to be saved.

[0043] Also, for example, a mounting system according to a thirteenth aspect of the present disclosure is a mounting system according to any one of the first to twelfth aspects, further comprising a supply device that supplies at least one of the feeder and the component holder to the mounting apparatus, the supply device being configured to be able to transfer at least one of the feeder and the component holder to a temporary storage area, and the placement section and the one or more antennas may be provided in the temporary storage area.

[0044] This makes it possible to identify the position of at least one of the feeder and the component container even in the temporary storage area.

[0045] Also, for example, a mounting system according to a fourteenth aspect of the present disclosure is a mounting system according to any one of the first to thirteenth aspects, and the first processing unit may be provided in a mounting device that mounts the component on a mounting target.

[0046] As a result, the mounting device executes the process for identifying the position of the target object, making it possible to reduce the amount of communication between the mounting device and other devices for this process.

[0047] Also, for example, a mounting system according to a fifteenth aspect of the present disclosure may be a mounting system according to any one of the first to fourteenth aspects, and may further include a second processing unit that determines, based on the positions of each of the plurality of objects identified by the first processing unit, whether or not an appropriate object corresponding to the position is located at the position.

[0048] This allows a determination as to whether or not the placed object is different, thereby making it possible to prevent an incorrect component from being mounted.

[0049] Also, for example, a mounting system according to a sixteenth aspect of the present disclosure may be a mounting system according to the fifteenth aspect, in which one of the first processing unit and the second processing unit is provided in a mounting device that mounts the component on a mounting target, and the other of the first processing unit and the second processing unit is provided in an apparatus arranged in an area different from a floor on which the mounting device is installed.

[0050] As a result, the first processing unit and the second processing unit are provided in different devices, so that the processing load can be distributed.

[0051] Furthermore, for example, a mounting system according to a seventeenth aspect of the present disclosure may be a mounting system according to any one of the first to sixteenth aspects, wherein the one or more antennas include two or more antennas, the multiple objects are arranged side by side at a predetermined interval, and two adjacent antennas among the two or more antennas are arranged side by side at a distance greater than the predetermined interval.

[0052] This allows the number of antennas to be reduced by increasing the spacing between the antennas.

[0053] Furthermore, for example, a mounting system according to an eighteenth aspect of the present disclosure is the mounting system according to any one of the first to seventeenth aspects, and the one or more antennas may be formed on a single substrate.

[0054] This allows one or more antennas to be implemented at a lower cost.

[0055] Furthermore, for example, a mounting system according to a 19th aspect of the present disclosure may be a mounting system according to any one of the 1st to 18th aspects, comprising a plurality of antennas as the one or more antennas, and the mounting system may further comprise a control device having a circuit for generating a transmission signal, and for causing each of the plurality of antennas to transmit radio waves corresponding to the transmission signal that has passed through a phase shifter for adjusting the phase of the transmission signal.

[0056] This allows the directivity of radio waves emitted from multiple antennas to be changed by the phase of the transmission signal, thereby expanding the tag detection range, and thus further reducing the number of antennas for reading tag information, thereby realizing a mounting system that can further reduce the space required for components for reading tag information.

[0057] Also, for example, an implementation system according to a 20th aspect of the present disclosure may be the implementation system according to the 19th aspect, wherein the control device transmits the transmission signal with the phase adjusted to each of the multiple antennas based on first phase information indicating the phase of the transmission signal for each of the multiple antennas and second phase information indicating the phase of the transmission signal for each of the multiple antennas, the second phase information being different from the first phase information, and the first processing unit may identify the positions of the multiple objects in the specified direction based on radio waves received from the tags of each of the multiple objects when radio waves based on the first phase information are transmitted and radio waves received from the tags of each of the multiple objects when radio waves based on the second phase information are transmitted.

[0058] This makes it possible to expand the detection range of the tag by the reception intensity distribution of each of the first phase information and the second phase information without complicating the configuration of multiple antennas. Also, when the reception intensity distribution of each of the first phase information and the second phase information is used for learning the learning model, the amount of data for learning increases, and therefore the accuracy of position determination using machine learning can be improved.

[0059] Also, for example, a mounting system according to a 21st aspect of the present disclosure may be the mounting system according to the 19th aspect, wherein the antenna is an antenna element constituting an array antenna, the control device transmits third phase information indicating the phase of the transmission signal for each antenna element and fourth phase information indicating the phase of the transmission signal for each antenna element, the fourth phase information being different from the third phase information, together with the transmission signal to the array antenna, and the first processing unit may identify the positions of the multiple objects in the specified direction based on radio waves received from the tags of each of the multiple objects when radio waves based on the third phase information are transmitted and radio waves received from the tags of each of the multiple objects when radio waves based on the fourth phase information are transmitted.

[0060] This makes it possible to expand the detection range of the tag by the reception intensity distribution of each of the third phase information and the fourth phase information without complicating the configuration of the control device. Also, when the reception intensity distribution of each of the third phase information and the fourth phase information is used for learning the learning model, the amount of data for learning increases, so that the accuracy of position determination using machine learning can be improved.

[0061] Furthermore, a mounting support device according to a twenty-second aspect of the present disclosure is a mounting support device that identifies positions of a plurality of objects in a mounting system that includes a placement section capable of arranging at least one of a component container that stores components and a feeder to which the component containers are attached in a predetermined direction, and one or more antennas configured to communicate with tags provided on a plurality of objects including a plurality of the feeders arranged in the placement section or a plurality of the component containers arranged in the placement section, wherein the number of the one or more antennas is less than the number of the objects that can be arranged in the placement section, and the mounting support device is configured to identify the position of each of the plurality of objects in the predetermined direction based on the signal strength of radio waves received by the one or more antennas from the tag of each of the plurality of objects. Furthermore, a mounting support method according to a 23rd aspect of the present disclosure is a mounting support method for determining positions of multiple objects in a mounting system including an arrangement section capable of arranging multiple component containers that store components and / or feeders to which the component containers are attached in a predetermined direction, and one or more antennas configured to communicate with tags provided on multiple objects including the multiple feeders arranged in the arrangement section or the multiple component containers arranged in the arrangement section, wherein the number of the one or more antennas is less than the number of objects that can be arranged in the arrangement section, and the one or more antennas determine the position of each of the multiple objects in the predetermined direction based on the signal strength of radio waves received by the one or more antennas from the tags of each of the multiple objects.

[0062] This provides the same effects as the above mounting system.

[0063] These general or specific aspects may be realized by 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 by any combination of the system, the method, the integrated circuit, the computer program, or the recording medium. The program may be stored in the recording medium in advance, or may be supplied to the recording medium via a wide area communication network including the Internet.

[0070] (Embodiment 1) Hereinafter, a component mounting system according to the present embodiment will be described with reference to FIGS. 1A to 11. FIG.

[0071] [1-1. Configuration of component mounting system] First, the configuration of a component mounting system according to the present embodiment will be described with reference to Fig. 1A to Fig. 8. Fig. 1A is a diagram showing a schematic configuration of a component mounting line according to the present embodiment. Fig. 1B is a diagram showing a schematic configuration of a component mounting system 10 according to the present embodiment.

[0072] As shown in FIG. 1A, the component mounting system 10 includes a plurality of production devices (M1 to M7) constituting a component mounting line. The plurality of production devices includes at least one component mounting device 20 (see FIG. 1B). The component mounting line mounts components on a mounting target such as a board, and produces a circuit board (a board on which components are mounted). Specifically, the component mounting line includes a board supply device M1, a board transfer device M2, a printing device M3, component mounting devices M4 and M5 (two component mounting devices 20 are connected in series), a reflow device M6, and a board recovery device M7, and these plurality of production devices (M1 to M7) are connected in series. Each of the plurality of production devices (M1 to M7) is connected to a management device via a communication network. The plurality of production devices (M1 to M7) can use known equipment used in known component mounting lines.

[0073] When a component mounting line starts producing circuit boards, it is necessary to replenish components such as components to be mounted on the boards. Also, the operating units used by the production equipment (M1 to M7) may be changed. For this reason, component mounting system 10 is equipped with a supply device that supplies either the operating units or components to the production equipment (M1 to M7). As shown in FIG. 1B, component mounting system 10 is equipped with a tape cassette supply device 40. Tape cassette supply device 40 is an example of a supply device. Component mounting system 10 is an example of a mounting system.

[0074] The component mounting device 20 is a device that mounts components supplied by a component supply unit 31 provided on a carriage 30 on a mounting target such as a board 50. Specifically, the component mounting device 20 includes a component mounting device main body 20a (device main body) and a carriage 30. The component mounting device main body 20a includes a head 21 that takes out components (not shown) (components supplied from the component supply unit 31) on the component supply unit 31 of the carriage 30 and transfers and mounts them on the board 50, a board transport unit 22 that transports the board 50 on which the components are mounted by the head 21 to a downstream reflow device (for example, the reflow device M6 shown in FIG. 1A), and a positioning device 23 that positions the carriage 30. The component mounting device 20 is an example of a mounting device. The component supply unit 31 is an example of a working unit.

[0075] The dolly 30 is a dolly that is connected to the component mounting apparatus main body 20a by being positioned by the positioning device 23. The dolly 30 includes a component supply unit 31 having a feeder (see FIGS. 2 and 4) described later and the like, a first tape cassette support section 70 (see FIG. 2) that detachably holds a plurality of tape cassettes 60 that store rolls of carrier tape, and a feeder support section 75 (see FIG. 2) that detachably holds a feeder (see FIGS. 2 and 4). Each feeder support section 75 is arranged in the X-axis direction so as to be paired with each first tape cassette support section 70. The dolly 30 has a configuration that allows a plurality of feeders to be arranged in the X-axis direction, to which a component container (case 315 or tape cassette 60 (for example, roll 80 shown in FIG. 6)) that contains components is attached.

[0076] It should be noted that the X-axis direction is an example of a predetermined direction, the dolly 30 is an example of a dolly section, and the feeder support section 75 and the first tape cassette support section 70 are an example of a placement section.

[0077] The tape cassette supplying device 40 is an example of a supplying device that supplies the tape cassette 60 to the first tape cassette support portion 70 of the dolly 30 or retrieves the tape cassette 60 from the first tape cassette support portion 70. In other words, the tape cassette 60 is an example of a member that is supplied to the supplying device, and a holding portion that holds the tape cassette 60 provided in the tape cassette supplying device 40 is an example of a placement portion. In addition, the tape cassette supplying device 40 is disposed, for example, spaced apart from the component mounting device 20.

[0078] Furthermore, the tape cassette supplying device 40 can transfer the tape cassette 60 from the tape cassette supplying device 40 to the temporary storage site. Fig. 3 is a diagram showing an example of the arrangement of the tape cassette 60 in the temporary storage site 700 according to this embodiment. Note that in Fig. 3, for the sake of convenience, the tag 615t is illustrated by a solid line. Furthermore, the temporary storage site 700 is arranged, for example, on a production floor (floor) on which the component mounting device 20 is arranged, and is configured to include an arrangement section that temporarily arranges and arranges the tape cassettes 60 and the like.

[0079] For example, as shown in FIG. 3, an antenna stand 701 is disposed in the temporary storage area 700, and the antenna stand 701 has a configuration capable of holding materials to be supplied to the production devices (M1 to M7) or materials collected from the production devices (M1 to M7). Specifically, the antenna stand 701 is capable of holding a tape cassette 60. The antenna stand 701 is also provided with one or more antennas 702 configured to be capable of receiving wireless signals from tags 615t provided on the multiple tape cassettes 60. The antenna stand 701 may hold the tape cassettes 60 such that the tags 615t of the tape cassettes 60 are positioned on the antenna 702. A cover may be provided on the antenna 702 (for example, between the antenna 702 and the held tape cassette 60). The cover may be configured without including a metal material. The antenna stand 701 is an example of an arrangement unit, and the antenna 702 is an example of one or more antennas.

[0080] The supply device (tape cassette supply device 40) may be capable of supplying or recovering at least one of the case 315, the cassette feeder 311 (or a bulk feeder described later), etc., in place of the tape cassette 60 or together with the tape cassette 60. The printing device M3 uses a printing mask having a pattern formation area in which a plurality of openings are formed, to print a pattern of solder on a mounting target such as a board. For example, the supply device may be capable of supplying or recovering a printing mask (not shown). In this case, the supply device is configured to be capable of transferring at least one of the case 315, the cassette feeder 311 (or a bulk feeder described later), the printing mask (not shown), etc., to the temporary storage area 700. In this way, the object transferred to the temporary storage site 700 is not limited to the tape cassette 60, but may be the case 315, the cassette feeder 311 (or a bulk feeder described later), a printing mask, a board 50 before components are mounted, a circuit board (either a finished product or a work-in-progress), an automated item 318 (see FIG. 2) for setting tape components in a feeder, or the like. The temporary storage site 700 may be provided in a component mounting line (for example, a device having a storage function constituting the component mounting line) or outside the component mounting line (for example, a device having a storage function that is not physically connected to the component mounting line). When the temporary storage site 700 is provided in a component mounting line, the travel distance of the supply device when supplying components to the production devices (M1 to M7) is short, and therefore the time required for supplying the components is reduced.

[0081] Next, details of the dolly 30 will be described with reference to Fig. 2. Fig. 2 is a perspective view showing the dolly 30 according to the present embodiment. Note that Fig. 2 illustrates only the cassette feeders 311 at both ends in the X-axis direction out of the multiple cassette feeders 311, and illustrates only the tape cassettes 60 at both ends in the X-axis direction out of the multiple tape cassettes 60.

[0082] 2, the cart 30 has a component supply unit 31, a plurality of first tape cassette support parts 70, a plurality of feeder support parts 75, and a cart body 32 that supports these. The component supply unit 31 is equipped with a cassette feeder 311 that supplies components contained in a tape cassette 60. The component mounting device 20 is also capable of using a bulk feeder (see FIG. 4) that is held by the feeder support part 75 in the same manner as the cassette feeder 311 and supplies bulk-shaped components contained in a case 315.

[0083] As shown in FIG. 2, the cassette feeder 311 holds an automated item 318 for loading a carrier tape into the cassette feeder 311 .

[0084] Incidentally, drawing the carrier tape into the cassette feeder 311 is an example of mounting the tape cassette 60 (component container) in a feeder. In the following, the cassette feeder 311 and the bulk feeder are also simply referred to as feeders.

[0085] The feeder may be provided with a tag (eg, RFID tag 317 in FIG. 4) that stores information about the feeder.

[0086] FIG. 4 is a side view showing bulk feeder 317 according to this embodiment.

[0087] As shown in FIG. 4, a case 315 for accommodating bulk parts is attached to the bulk feeder 317. The case 315 is held on the upper surface of the bulk feeder 317. The case 315 is provided with a tag 315t for storing information about the parts accommodated in the case 315. The information about the parts includes, for example, the type, size, and shape of the parts accommodated in the case 315. The bulk feeder 317 is provided with a tag 317t for storing information about the feeder. The tag 315t may also include information about the feeder to which the case 315 is attached. The information about the feeder includes the type of the feeder, identification information that uniquely identifies the feeder, the size, and the like. The case 315 is an example of a part container.

[0088] It is preferable that antenna 314 is disposed directly below tag 317t when bulk feeder 317 shown in FIG. 4 is disposed in the arrangement section.

[0089] Next, an antenna for receiving radio signals from tags provided on a plurality of objects in the component mounting system 10 thus configured will be described. Fig. 5 is a diagram showing an example of an arrangement of tags and antennas provided on a plurality of objects according to this embodiment. The tags (e.g., tag 315t) are arranged side by side in a predetermined direction. The number of antennas (e.g., antenna 314) is less than the number of tags provided on the plurality of objects.

[0090] Here, the feeder held by the feeder support part 75 is an example of an object. The tape cassette supplying device 40 or the tape cassette 60 arranged in the first tape cassette support part 70 is an example of an object. A member arranged on an antenna stand provided in the temporary storage area is an example of an object. The case 315 held by the feeder support part 75 via the bulk feeder 317 is an example of an object.

[0091] Referring again to FIG. 2, in this embodiment, an antenna 314 for reading information of a tag (for example, at least one of tags 315t and 317t) shown in FIG. 4 is arranged on the feeder support section 75. The antenna 314 is configured to be able to communicate with tags of a plurality of objects including at least one of a plurality of cases 315 and a plurality of feeders arranged in the holding area 75a that holds a plurality of feeders arranged in the X-axis direction. The antenna 314 is arranged so that the information can be read from below the feeder. One or more antennas 314 are arranged. Note that the plurality of feeders here may include a plurality of either cassette feeders 311 or bulk feeders 317, or may include both cassette feeders 311 and bulk feeders 317.

[0092] In this embodiment, the number of antennas 314 is less than the number of feeders or cases 315 that can be arranged in holding area 75a. It can also be said that the number of antennas 314 is less than the number of slots (e.g., feeder support parts 75) arranged in holding area 75a. Holding area 75a is an area where multiple feeder support parts 75 are provided.

[0093] Furthermore, in this embodiment, an antenna 614 for reading information on a tag 615t shown in Fig. 6 is disposed on the first tape cassette support portion 70. The antenna 614 is configured to be able to communicate with tags of a plurality of objects, which are the plurality of tape cassettes 60 disposed in the holding area 70a. The number of antennas 614 is less than the number of tape cassettes 60 that can be disposed in the holding area 70a. It can also be said that the number of antennas 614 is less than the number of slots (e.g., first tape cassette support portions 70) disposed in the holding area 70a.

[0094] The antenna 314 has a plate-shaped substrate 314a. In addition, an antenna pattern 314b, which is a wiring, is formed on the substrate 314a. The antenna pattern 314b is a conductor pattern that meanders in a meandering shape, but is not limited to this. In the example of FIG. 2, one antenna pattern 314b is formed on one antenna 314. This makes it possible to suppress the occurrence of signal interference within the substrate 314a, thereby improving communication quality. The antenna pattern 314b or the antenna 314 is an example of an antenna.

[0095] The antenna 614 has a plate-shaped substrate 614a. An antenna pattern 614b, which is a wiring, is formed on the substrate 614a. The antenna pattern 614b is a conductor pattern that meanders in a meandering manner, but is not limited to this. The antenna pattern 614b or the antenna 614 is an example of an antenna.

[0096] It is sufficient that the antenna 314 is capable of communicating with at least one of the tags 315t provided on the case 315 and the tag 317t provided on the bulk feeder 317. The antenna 314 may also be capable of communicating with a tag (not shown) provided on the cassette feeder 311 and a tag (not shown) provided on the automated item 318 held in the cassette feeder 311. The antenna 614 may also be capable of communicating with a tag (not shown) provided on the automated item 318 held in the cassette feeder 311. In the following, an example in which the antenna 314 communicates with the tag 315t provided on the case 315 will be mainly described.

[0097] 5, the arrangement interval P1 between adjacent antennas 314 is larger than the arrangement interval P2 between tags 315t. The arrangement intervals of cassette feeders 311 and cases 315 are the same as the arrangement interval P2 between tags 315t. The antennas 314 are arranged at, for example, equal intervals, but are not limited to this.

[0098] When the arrangement intervals P1 and P2 are not equal intervals, the arrangement intervals P1 and P2 may be the average value, median, mode, maximum value, minimum value, or the like, of a plurality of arrangement intervals.

[0099] The RFID reading unit 24 is connected to each of the multiple antennas 314 and performs wireless communication with the tag 315t via the multiple antennas 314. The RFID reading unit 24, for example, transmits radio waves to the tag 315t. The radio waves are received by each of the multiple tags 315t. The RFID reading unit 24 can also receive radio waves from each of the multiple tags 315t. The RFID reading unit 24 is realized by a reader device. The RFID reading unit 24 has a circuit for transmitting a received signal, and when the RFID reading unit 24 receives radio waves by the antenna 314, it transmits the received signal as an electric signal generated by receiving the radio waves, and acquires the strength of the received signal. The RFID reading unit 24 is an example of a control device.

[0100] In this way, since the number of antennas 314 is smaller than the number of tags 315t, the number of connection terminals required for the RFID reading unit 24 can be reduced compared to the case where the number of antennas 314 and tags 315t is the same. This prevents the RFID reading unit 24 from becoming larger. Furthermore, since the number of wires connecting the antennas 314 and the RFID reading unit 24 can be reduced, the wiring is prevented from becoming complicated.

[0101] If the number of antennas 314 is less than the number of cases 315 that can be placed in the holding area 75a, it is necessary to identify the case 315 (tag 315t) placed in which position the radio waves received by one or more antennas 314 were transmitted. For example, this is because it is necessary to determine whether or not the parts housed in the attached case 315 correspond to the attached position. The identification of the position of each case 315 will be described later.

[0102] Referring again to FIG. 2, the cassette feeder 311 pulls out the carrier tape from the tape cassette 60 (first tape cassette 61 or second tape cassette 65) held by the first tape cassette support portion 70, and transports the components stored in the carrier tape to a position for removal by the head 21.

[0103] The first tape cassette 61 is supported by a first tape cassette support portion 70 formed in the holding area 70a. The roll body 80 of the first tape cassette 61 is an example of a first component housing.

[0104] The second tape cassette 65 is supported by a first tape cassette support portion 70 formed above (on the positive side of the Z axis) the holding area 70a. The roll body 80 of the second tape cassette 65 is an example of a second component housing.

[0105] In the example of FIG. 2, the first tape cassette 61 and the second tape cassette 65 are held below the cassette feeder 311, but the present invention is not limited to this.

[0106] In this embodiment, the antenna 614 is disposed in both the holding area 70a that holds a plurality of first tape cassettes 61 arranged in the X-axis direction and the holding area 70b that holds a plurality of second tape cassettes 65 arranged in the X-axis direction. The antenna 614 disposed in the holding area 70a is configured to be able to communicate with a tag 615t of the first tape cassette 61 shown in FIG. 6, which will be described later. The antenna 614 disposed in the holding area 70b is configured to be able to communicate with a tag 615t of the second tape cassette 65 shown in FIG. 6. The antenna 614 is disposed so that the information can be read from below the tape cassette 60, but may be disposed so that the information can be read from above the tape cassette 60. For example, the antenna 614 may be disposed below the tape cassette 60, or may be disposed above the tape cassette 60.

[0107] The first tape cassette support portion 70 (an example of a first arrangement portion) provided in the holding area 70a and the first tape cassette support portion 70 (an example of a second arrangement portion) provided in the holding area 70b hold the first tape cassette 61 and the second tape cassette 65 such that the tag 615t (first tag) provided on the first tape cassette 61 and the tag 615t (second tag) provided on the second tape cassette 65 are arranged at different positions from each other in the vertical direction (Z-axis direction). The first tag is provided on the lower surface (first side surface) of the first tape cassette 61, and the second tag is provided on the lower surface (second side surface) of the second tape cassette 65. For example, the first tape cassette support part 70 provided in the holding area 70a and the first tape cassette support part 70 provided in the holding area 70b are configured to be able to arrange the first tape cassette 61 and the second tape cassette 65 so that the vertical positions of the first side surface and the second side surface are different from each other. For example, it can also be said that a tag 615t is provided on a side surface of a component container (e.g., tape cassette 60), and the first component container (e.g., first tape cassette 61) and the second component container (e.g., second tape cassette 65) are held in the first arrangement part and the second arrangement part so that the positions of the side surfaces are different.

[0108] In this case, the positions of the first tape cassette 61 (e.g., the roll body 80) and the second tape cassette 65 (e.g., the roll body 80) in the X-axis direction may be identified based on radio signals via radio waves received by one or more antennas 614 from each of the first tag and the second tag (hereinafter also simply referred to as based on radio waves). Specifically, the position of the first tape cassette 61 (e.g., the roll body 80) in the X-axis direction may be identified based on radio waves received by one or more antennas 614 (an example of a first antenna) provided in the holding area 70a from each of the first tags, and the position of the second tape cassette 65 (e.g., the roll body 80) in the X-axis direction may be identified based on radio waves received by one or more antennas 614 (an example of a second antenna) provided in the holding area 70b from each of the second tags. Furthermore, each of the one or more antennas 614 may be provided to be capable of communicating with a tag 315t of a case 315 attached to each of one or more feeders (e.g., bulk feeder 317) arranged in holding area 75a. The position of case 315 in the X-axis direction may be identified based on the distribution of reception intensity of radio waves acquired by one or more antennas 614 from tag 315t of one or more cases 315.

[0109] For example, the number of the one or more first antennas is less than the number of first component containers that can be arranged in the first arrangement section, and the number of the one or more second antennas is less than the number of second component containers that can be arranged in the second arrangement section. For example, the holding areas 70a, 70b that hold the tape cassettes 60 (e.g., the rolls 80) are divided into a plurality of zones (e.g., the holding areas 70a and 70b), and antennas 614 are provided individually corresponding to each zone, and it can be said that the number of antennas 614 provided is less than the number of tape cassettes 60 that can be held in the zone.

[0110] The positions of the antennas 314 and 614 are not limited to those shown in FIG. 2, and may be located, for example, between the cassette feeder 311 and the tape cassette 60 in the vertical direction.

[0111] Comparing the first tape cassette 61 and the second tape cassette 65, they have roughly the same basic structure but differ in size. The second tape cassette 65 is smaller than the first tape cassette 61. The structures of the first tape cassette 61 and the second tape cassette 65 will be described below with reference to FIG. 6. FIG. 6 is an exploded perspective view in which a portion of the tape cassette 60 according to this embodiment is disassembled. FIG. 6 shows the tape cassette 60 with the cover body 622 (see FIG. 2) removed.

[0112] 6, the tape cassette 60 includes a storage section 62 and a tape feed section 63. The tape feed section 63 is a section that feeds out the leading end of the carrier tape stored in the storage section 62 to the component supply unit 31.

[0113] The tape cassette 60 has a flat outer shape with its thickness direction aligned in the X-axis direction. An upper surface 611 of the tape cassette 60 is formed parallel to the XY plane, and a base end surface 612 in the negative Y-axis direction is formed parallel to the XZ plane.

[0114] The storage unit 62 stores a roll 80 around which a carrier tape is wound. Specifically, the storage unit 62 has a frame body 621 in which the roll 80 is set, and a pair of cover bodies 622 (see FIG. 2), and the pair of cover bodies 622 are attached to the frame body 621 so as to sandwich the frame body 621 in the X-axis direction. A tag 615t is provided on a side surface of the storage unit 62. The storage unit 62 is also called a cassette.

[0115] A gripped portion 625 is provided above the frame body 621 via the tape feed portion 63 .

[0116] The gripped portion 625 is a portion that is gripped by the tape cassette supplying device 40. In other words, when the tape cassette 60 is supplied to the first tape cassette support portion 70 by the tape cassette supplying device 40, or when the tape cassette 60 is removed from the first tape cassette support portion 70, the gripped portion 625 is gripped by the holding portion 43 (see FIG. 7 ) of the tape cassette supplying device 40. The gripped portion 625 has L-shaped notches formed on both sides in the Y-axis direction, and the holding portions 43 of the tape cassette supplying device 40 are adapted to be inserted into the notches.

[0117] A tag 626 that stores various information is provided on the upper surface 611 of the frame body 621. The information stored in the tag 626 includes information about the parts stored in the carrier tape forming the roll body 80 or information about the tape cassette 60. The information about the parts includes the type, size, etc. of the parts. The information about the tape cassette 60 includes the type, size, etc. of the tape cassette 60. The information stored in the tag 626 is read by an antenna 423 (see FIG. 7) provided in the holding portion 43. The information stored in the tag 626 may be the same as or different from the information stored in the tag 615t.

[0118] Next, the tape cassette supplying device 40 will be described with reference to Fig. 7. Fig. 7 is a perspective view showing a schematic configuration of the tape cassette supplying device 40 according to the present embodiment. Fig. 7(a) shows a schematic configuration of the tape cassette supplying device 40 according to the present embodiment, and Fig. 7(b) shows an enlarged view of the tape cassette 60 housed in the tape cassette supplying device 40. Note that Fig. 7 also shows the holding portion 43.

[0119] 7(a), the tape cassette supplying device 40 is a movable device that is transported on a floor surface by a transport vehicle 490, for example an AGV (Automatic Guided Vehicle), and is a device that supplies and collects tape cassettes 60 to and from component mounting devices 20. In other words, the tape cassette supplying device 40 is a device that moves between a plurality of component mounting devices 20 by the transport vehicle 490, and transfers the tape cassette 60 to each component mounting device 20.

[0120] The tape cassette supplying device 40 is transported by the transport vehicle 490 and is connected to the end of the component mounting device 20 in the negative Y-axis direction (see FIG. 1B). Therefore, in the connected state, the tape cassette supplying device 40 and the component mounting device 20 are arranged side by side in the Y-axis direction. The tape cassette supplying device 40 supplies the component mounting device 20 with a storage unit 62 for storing a roll body 80.

[0121] Arranged inside the tape cassette supply device 40 are a support section 42 that supports the tape cassette 60, a holding section 43 that holds the tape cassette 60 supported by the support section 42, and a support section moving mechanism (not shown) that moves the support section 42.

[0122] The support section 42 has a plurality of second tape cassette support sections 421 which individually support each tape cassette 60, and a mounting base 422 on which the plurality of second tape cassette support sections 421 are mounted. Each second tape cassette support section 421 is a slot extending in the Y-axis direction, and is arranged along the X-axis direction with respect to the mounting base 422. In the connected state, each second tape cassette support section 421 faces each first tape cassette support section 70 of the dolly 30 in the Y-axis direction. In other words, the Y-axis direction is an example of a facing direction.

[0123] The holder 43 is also provided with an antenna 423 for reading information from the tag 626 of the tape cassette 60 held by the holder 43. The number of antennas 423 is smaller than the number of tape cassettes 60 (i.e., tags 626) that can be held by the holder 43.

[0124] The area in which the holding unit 43 is provided is an example of the arrangement unit. That is, the arrangement unit and the antenna 423 may be provided in the tape cassette supplying device 40. Also, together with the antenna 423 or instead of the antenna 423, an antenna for reading information from the tag 615t of the tape cassette 60 may be provided in the tape cassette supplying device 40 or the transport vehicle 490.

[0125] In the above, an example has been described in which the component mounting system 10 includes the tape cassette supplying device 40 that supplies and collects the tape cassette 60 to the component mounting device 20, but the present invention is not limited to this. A supplying device that supplies and collects the cassette feeder 311 (or the bulk feeder 317) or the case 315 to the component mounting device 20 may be provided together with the tape cassette supplying device 40 or instead of the tape cassette supplying device 40. In such a supplying device, like the tape cassette supplying device 40, one or more antennas are arranged, the number of which is less than the number of the cassette feeders 311 (or the bulk feeders 317) or the cases 315 that the supplying device can hold, and the one or more antennas can read information from all of the tags of the cassette feeders 311 (or the bulk feeders 317) or the cases 315 that are greater than the number of the antennas. In addition, such a supplying device is configured to be able to transfer the cassette feeders 311 (or the bulk feeders 317) or the cases 315 to a temporary storage area. That is, the antenna provided at the temporary storage site can read information from the tag of the cassette feeder 311 or the case 315. In addition, the antenna 702 provided at the temporary storage site 700 may be capable of reading information from a tag (not shown) provided on the automated item 318 held by the cassette feeder 311.

[0126] Next, the functional configuration of the component mounting system 10 will be described with reference to Fig. 8. Fig. 8 is a block diagram showing the functional configuration of the component mounting system 10 according to the present embodiment.

[0127] As shown in Fig. 8, component mounting system 10 includes component mounting apparatus 20, floor control device 11, and upper system 12. Note that Fig. 10 shows a block diagram of a case where only cassette feeder 311 is provided as a feeder.

[0128] The component mounting apparatus 20 has an RFID reading unit 24 connected to the antenna 314, a cart control unit 25, and an equipment control unit 26 (NCIO: Numerical Control Input / Output). Note that in FIG. 8, the antenna 614 connected to the RFID reading unit 24 is not shown.

[0129] The cart control unit 25 is a control device that controls each component of the cart 30 connected to the component mounting device main body 20a of the component mounting device 20. The cart control unit 25 may, for example, control the component supply unit 31 to supply components. The cart control unit 25 has a CPU (Central Processing Unit) and a memory, and each function is realized by the CPU executing a program stored in the memory.

[0130] The equipment control unit 26 is a control device that controls each component of the component mounting apparatus 20. The equipment control unit 26 controls, for example, each component of the component mounting apparatus 20 except for the dolly 30. The component mounting apparatus 20 controls the operation of the head 21, the board transport unit 22, etc. The equipment control unit 26 has a CPU, a memory, etc., and each function is realized by the CPU executing a program stored in the memory.

[0131] The mounting support device according to the present embodiment may be configured to include an equipment control unit 26, and may further be configured to include an RFID reading unit 24.

[0132] The floor control device 11 is a control device arranged on the same floor as the component mounting device 20, and is separate from the component mounting device 20. There are multiple component mounting devices 20 on the floor, and the floor control device 11 monitors and controls the multiple component mounting systems 10. The floor control device 11 is connected to the component mounting devices 20 (e.g., equipment control unit 26) so as to be able to communicate with them. The upper system 12 has a CPU, memory, etc., and each function is realized by the CPU executing a program stored in the memory.

[0133] The upper system 12 is a control device that is placed in a location different from the floor where the component mounting device 20 is placed. The upper system 12 is placed, for example, in a remote location different from the building (e.g., a factory) where the component mounting device 20 is placed, and is connected to the floor control device 11 so as to be able to communicate (e.g., be able to communicate wirelessly). The upper system 12 has a CPU, a memory, etc., and each function is realized by the CPU executing a program stored in the memory.

[0134] Any of the above control devices specifies the positions of a plurality of objects held in the holding area 70a or the like in the X-axis direction (first process). Furthermore, any of the above control devices determines whether or not a proper component container corresponding to an object (cassette feeder 311 or tape cassette 60) placed in the first tape cassette support unit 70, the feeder support unit 75, or the like (second process) is held in the holding area 70a or the like based on information on the tag 315t or the like whose position has been specified. If a processing unit that executes the first process is defined as a first processing unit and a processing unit that executes the second process is defined as a second processing unit, the function of the first processing unit may be provided in the component mounting device 20. Furthermore, the function of the first processing unit may be provided in the component mounting device 20, and the function of the second processing unit may be provided outside the component mounting device 20. The function of the second processing unit may be provided in a device (for example, the upper system 12) that is placed in an area different from the floor on which the component mounting device 20 is installed. In the following, an example in which the equipment control unit 26 functions as the first processing unit and the second processing unit will be described.

[0135] [1-2. How to identify the location of an object] Next, an example of identifying the position of an object in the X-axis direction by radio waves received from each of tags 315t, etc. will be described with reference to Fig. 9 and Fig. 10. Fig. 9 is a diagram showing the arrangement of antenna 314 and tag 315t used in verification according to this embodiment.

[0136] As shown in FIG. 9, four antennas 314 (ant1 to ant4) are arranged, and above them, 15 tags 315t are arranged at predetermined intervals from the antennas 314 via spacers 315s.

[0137] Under these conditions, signals are output in sequence from the four antennas 314 using radio waves, and when the tag 315 t receives the radio signal, it returns the radio signal to the RFID reader 24 via the antenna 314 .

[0138] Fig. 10 is a diagram showing the distribution of radio wave reception strength (received signal strength: RSSI) for each antenna 314 according to this embodiment. Fig. 10 shows the distribution of radio wave reception strength received under the conditions shown in Fig. 9, with the horizontal axis showing the tag 315t number (1 to 15) and the vertical axis showing RSSI. Note that the received signal strength indicates the signal strength of the electric signal (electric signal corresponding to the radio wave) flowing in the RFID reading unit 24 when the radio wave from the tag 315t is received.

[0139] The radio waves from the tag 315t contain identification information for identifying the tag 315t. Therefore, as shown in Fig. 10, the RFID reading unit 24 can obtain information indicating the reception strength of radio waves from a tag 315t having which identification information (e.g., which number) by the radio waves received from the tag 315t. At this point, it is not known in which position of the slot the tag 315t having which identification information is placed.

[0140] Therefore, the equipment control unit 26 uses the first learning model to identify the position of the case 315 in the X-axis direction (i.e., which slot has the tag 315t with which identification information placed in it). The first learning model is a machine learning model that uses the reception strength of radio waves received by each of one or more antennas 314 (four antennas 314 in this case) from the tag 315t of the target object (case 315 in this case) as input information, and learns information about the position of the managed object in which the tag 315t is provided in the X-axis direction (predetermined direction) as correct answer data. The information about the position in the X-axis direction includes, for example, information indicating the position of the slot (for example, an address).

[0141] The equipment control unit 26 identifies which feeder support 75 (which slot) of the multiple feeder support 75 the case 315 attached to has transmitted the wireless signal received by the antenna 314 based on the reception intensity distribution shown in Fig. 10. The equipment control unit 26 inputs the reception intensity distribution shown in Fig. 10 into a trained model trained by supervised learning using the position of the feeder support 75 as correct answer data, and identifies the output obtained as the position of the case 315 that transmitted the wireless signal. The reception intensity distribution shown in Fig. 10 is an example of information based on signal intensity.

[0142] In addition, in the trained model, a position determination threshold, weighting parameters, etc. for matching the receiving strength distribution of the radio signal received by antenna 314 with the slot position in which the object that transmitted the radio signal (e.g., case 315) is set can be set by learning.

[0143] By using the above method, even if the number of antennas 314 is less than the number of cases 315, the positions at which cases 315 are attached can be identified with high accuracy.

[0144] Although one trained model may be generated, more preferably, multiple trained models are generated according to the type of the holding area 75a. The type of the holding area 75a is the number of slots, but may also be, for example, the length of the holding area 75a in the X-axis direction, the width of the slots, etc. In this case, for example, the reception intensity distribution shown in FIG. 10 is acquired for each number of slots, and a trained model is generated for each number of slots. The equipment control unit 26 acquires information indicating the number of slots in the holding area 75a, determines one trained model according to the acquired information indicating the number of slots, and identifies the position of the tag 315t (the position of the case 315) using the determined trained model.

[0145] In the example of FIG. 2, the antenna 314 is described as being provided below the cassette feeder 311, but it may be provided above the cassette feeder 311. If the feeder is a bulk feeder 317, the antenna 314 may be provided below the bulk feeder 317 or above the case 315. In this case, when receiving radio waves from the tag 315t of the case 315, a plurality of trained models may be generated according to the number of components in the case 315. This is because, if the components housed in the case 315 contain metal, the signal strength of the radio waves received by the antenna 314 changes according to the number of components in the case 315.

[0146] For example, a first learning model, which is a trained model, may be generated by the method described above based on the distribution of radio wave reception strength acquired from the tag 315t when the number of parts in the case 315 is a first number (e.g., a maximum number), and a second learning model, which is a trained model, may be generated by the method described above based on the distribution of radio wave reception strength acquired from the tag 315t when the number of parts in the case 315 is a second number (e.g., half the maximum number) that is less than the first number. The generation of the first learning model and the second learning model may be executed by, for example, the equipment control unit 26. The second trained model is trained by machine learning using, for example, information based on a second reception signal strength indicating the signal strength of the radio wave received when the number of parts contained in the part container is a different number from when the radio wave of the first reception signal strength is received as input information, and information on the position in the X-axis direction (predetermined direction) of the managed object in which the tag 315t is provided at that time as correct answer data.

[0147] The equipment control unit 26 may switch between the first learning model and the second learning model depending on the number of parts contained in the case 315 attached to the bulk feeder 317 arranged in the arrangement unit. Three or more learned models may be generated depending on the number of parts in the case 315. The number of parts contained in the case 315 may be specified based on, for example, the number of parts when unused and the number of productions (number of parts mounted) using the case 315. For example, the number of parts currently contained may be stored in the tag 315t of the case 315.

[0148] In addition, the trained model (third trained model) may be generated in multiple ways depending on at least one of the number of objects arranged in the arrangement section (holding area 75a, holding areas 70a and 70b, the area where holding section 43 is provided, support section 42, and antenna stand 701 of temporary storage area 700) and the positions at which the objects are attached. Specifically, multiple trained models may be generated in multiple ways depending on at least one of the number of cases 315 arranged in holding area 75a and the positions at which the cases 315 are attached. This is because if the ratio of the area occupied by the cases 315 to the holding area 75a changes or the position of the area occupied by the cases 315 changes, the signal strength of the radio waves received by antenna 314 changes. In this case, equipment control section 26 may switch between the first trained model and the third trained model depending on at least one of the number and positions of the cases 315 held in multiple bulk feeders 317 arranged in the arrangement section. Here, the third trained model is trained by machine learning using, as input information, information based on the reception strength (third received signal strength) of radio waves acquired when at least one of the number and positions of the cases 315 held in the multiple bulk feeders 317 arranged in the arrangement section is different from at least one of the number and positions when radio waves with the reception strength included in the input information used to train the first trained model are received, and information on the position in the X-axis direction (predetermined direction) of the managed object on which the tag 315t is provided at that time is used as correct answer data. The number and positions of the cases 315 can be identified, for example, by image analysis of an image captured of the arrangement section, or by a sensor arranged in the arrangement section (or the bulk feeder 317).

[0149] Also, for example, a plurality of learned models (fourth learned models) may be generated according to at least one of the number and positions of the feeders (cassette feeders 311 or bulk feeders 317) arranged in the placement section (the holding area 75a or the antenna stand 701 of the temporary storage area 700). Specifically, a plurality of learned models may be generated according to at least one of the number and positions of the bulk feeders 317 arranged in the holding area 75a. This is because when the ratio of the area occupied by the task unit to the holding area 75a or the position of the area occupied by the feeder changes, the signal strength of the radio waves received by the antenna 314 changes. In this case, the equipment control unit 26 may switch between the first learned model and the fourth learned model according to at least one of the number and positions of the multiple task units arranged in the placement section. Here, the fourth trained model is trained by machine learning using as input information information based on the reception strength (fourth received signal strength) of radio waves acquired when at least one of the number and position of task units arranged in the arrangement section is different from at least one of the number and position when radio waves with the reception strength included in the input information used to train the first trained model are received, and information on the position in the X-axis direction (predetermined direction) of the managed object on which the tag 315t is provided at that time is used as correct answer data. Note that the number and position of the task units can be identified, for example, by image analysis of an image captured of the arrangement section or by a sensor arranged in the arrangement section.

[0150] [1-3. Operation of component mounting system] Next, the operation of the component mounting system 10 configured as above will be described with reference to Fig. 11. Fig. 11 is a flowchart showing the operation (mounting support method) of the component mounting system 10 according to this embodiment.

[0151] 11, the RFID reader 24 starts tag detection (S10). Specifically, the RFID reader 24 sequentially transmits radio waves to each antenna 314, and receives radio waves transmitted from the tag 315t in response to the transmitted radio waves.

[0152] Next, the RFID reading unit 24 acquires the reception strength (RSSI) for each antenna 314 from the received radio waves (S20). The RFID reading unit 24 acquires the reception strength for each antenna 314 and each tag 315t. For example, if there are four antennas 314 and 15 tags 315t, 60 reception strengths are acquired. The RFID reading unit 24 outputs the acquired reception strength to the equipment control unit 26 via the cart control unit 25.

[0153] Next, the equipment control unit 26 uses the machine learning model to determine the tag position (S30). As described above, the equipment control unit 26 reads out a trained model that has been trained in advance, and determines that the output of the trained model obtained by inputting the coordinates of the three coordinate axes of the principal component analysis corresponding to the reception intensity into the read trained model is the tag position of the tag 315t. The tag position is the position in the X-axis direction (slot position) within the holding area 75a.

[0154] Next, the equipment control unit 26 associates the tag information included in the radio wave from the tag 315t with the position in the X-axis direction (slot position) in the holding area 75a (S40). This identifies the position (slot) of the case 315 in which the tag 315t is attached that has transmitted the signal.

[0155] Next, the equipment control unit 26 judges whether or not an appropriate case 315 corresponding to the position is held in the holding area 75a based on the position of the case 315 identified in step S30. That is, the equipment control unit 26 executes a component matching to check whether or not the type of component indicated in the tag information of the tag 315t of the case 315 identified in step S30 matches the type of component that should originally be placed at the position (S50). Information indicating the type of component that should originally be placed may be acquired from, for example, the floor control device 11 or the upper system 12, or may be stored in the component mounting device 20. In addition, the information may be acquired from, for example, a production plan, etc.

[0156] Next, the equipment control unit 26 executes a production judgment as to whether or not to start production (S60). That is, production is not performed until step S50, and production is started based on the judgment result of step S60. For example, the equipment control unit 26 judges to start production when the part types match in the part matching, and judges not to start production when the part types do not match in the part matching.

[0157] Next, the equipment control unit 26 notifies the host system 12 of the determination result of step S60 (S70). The equipment control unit 26 may also issue a notification according to the determination result of step S60. This allows a worker on the floor to be informed that the part types do not match, enabling a quick response when the case 315 is attached by mistake.

[0158] The component matching (S50) and production judgment (S60) according to the first embodiment may be performed by the upper system 12. In this case, the equipment control unit 26 notifies the upper system 12 of the result of step S40. By separating the processing unit that judges the position (S30) and associates the judged position with the tag information (S40) from the processing unit that executes the component matching (S50) and production judgment (S60) processes, the load on each processing unit is reduced. Therefore, it is possible to reduce the cost of the equipment control unit 26, and as a result, it is possible to reduce the cost of the component mounting device 20. Here, separation means that a plurality of processes are distributed and processed using different information processing devices.

[0159] (Modification of the first embodiment) The component mounting system according to this modification will be described below with reference to Fig. 12. Note that the following description will focus on the differences from the first embodiment, and descriptions of the same or similar contents as the first embodiment will be omitted or simplified.

[0160] Fig. 12 is a diagram showing a schematic diagram of an antenna 316 according to this modified example. In Fig. 12, only the upper part of the dolly 30a is shown.

[0161] As shown in FIG. 12, in the component mounting system according to this modification, the shape of an antenna 316 is different from that of the antenna 314 according to the first embodiment.

[0162] The antenna 316 has a substrate 316a that is elongated in the X-axis direction. A plurality of antenna patterns 316b, which are wiring, are formed on the substrate 316a. In other words, the plurality of antenna patterns 316b are formed on one substrate 316a.

[0163] This allows the cost of antenna 316 to be reduced compared to when one antenna is formed on one substrate.

[0164] A switch may be provided on the substrate 316a, and the switch may switch the connection between the multiple antenna patterns 316b and the RFID reading unit 24. This allows the amount of wiring connecting the antenna 316 and the RFID reading unit 24 to be reduced.

[0165] The same applies to antennas 423 and 614 according to embodiment 1. That is, antennas 423 and 614 may be realized by a single substrate on which a plurality of meandering antenna patterns are formed.

[0166] (Embodiment 2) [2-1. Configuration of component mounting equipment] The configuration of a component mounting device according to the present embodiment will be described with reference to Figs. 13 and 14. The following description will focus on the differences from the first embodiment. Fig. 13 is a diagram showing a schematic configuration of a component mounting device 1020 according to the present embodiment. The component mounting device 1020 according to the present embodiment differs from the component mounting device 20 according to the first embodiment in that the antenna 314 is disposed above the case 315. The component mounting system 10 according to the first embodiment may include the component mounting device 1020 instead of the component mounting device 20.

[0167] As shown in FIG. 13, the component mounting apparatus 1020 includes a component mounting apparatus main body 1110 (apparatus main body), a substrate transport section 1120, a carriage 1130, an X-axis moving mechanism 1140, a Y-axis moving mechanism 1150, a head 1160, a protective cover section 1170, and an antenna 314.

[0168] The board transport unit 1120 is disposed along the X-axis (along the transport direction of the board 1200) near the center of the component mounting apparatus main body 1110. The board transport unit 1120 transports the board 1200 carried in from the upstream side in a direction along the X-axis, and positions and holds the board 1200 on a mounting stage set for performing the component mounting operation.

[0169] The dolly 1130 is a dolly that is connected to the component mounting device main body 1110 of the component mounting device 1020. The dolly 1130 is, for example, detachable from a predetermined position of the component mounting device main body 1110. The dolly 1130 includes a component supply unit 31 having a bulk feeder 317 that aligns and supplies bulk-shaped components accommodated in a case 315. The component supply unit 31 arranges a plurality of the bulk feeders 317 in a predetermined direction (X-axis direction). For example, the dolly 1130 can hold a plurality of the bulk feeders 317 collectively. The dolly 1130 has a configuration that allows a plurality of cases 315, which are component containers that accommodate components, to be arranged in the X-axis direction. It can also be said that the dolly 1130 has an arrangement section that allows a plurality of the cases 315 to be arranged in the X-axis direction. The cart 1130 may have a configuration in which a plurality of cassette feeders 311 and tape cassettes 60 can be arranged side by side in the X-axis direction. Here, being detachable means that the cart 1130 can be connected to the component mounting device main body 1110 and the connection between the component mounting device main body 1110 and the cart 1130 can be released without destroying the component mounting device main body 1110 and the cart 1130.

[0170] A Y-axis movement mechanism 1150 equipped with a linear drive mechanism is disposed in the Y-axis direction at the end in the X-axis positive direction on the upper surface of the component mounting apparatus main body 1110, and two X-axis movement mechanisms 1140 similarly equipped with linear drive mechanisms are coupled to the Y-axis movement mechanism 1150 so as to be freely movable in the Y-axis direction. A head 1160 is attached to each of the two X-axis movement mechanisms 1140 so as to be freely movable in the X-axis direction.

[0171] Head 1160 places (mounts) components supplied from bulk feeder 317 arranged on carriage 1130 onto substrate 1200.

[0172] Component suction nozzles 1160a that can pick up and hold components and move up and down individually are attached to the head 1160. The head 1160 has a Z-axis lifting mechanism that lifts and lowers the component suction nozzles 1160a and a θ-axis rotation mechanism that rotates the component suction nozzles 1160a about the nozzle axis.

[0173] The protective cover part 1170 is a cover provided to ensure the safety of the worker during work so that the worker does not come into contact with movable parts such as the head 1160. The protective cover part 1170 is provided above the component supply unit 31 so as to separate the movable range of the head 1160 from the component supply unit 31.

[0174] The protective cover part 1170 has a shape that conforms to the bulk feeder 317 to which the case 315 is attached. Specifically, the protective cover part 1170 has a first part 1170a that covers the head 1160 side of the bulk feeder 317, and a second part 1170b that covers the bulk feeder 317 and is provided on the positive side of the Z axis from the first part 1170a. The second part 1170b is inclined, for example, along the upper surface of the case 315. The second part 1170b is inclined so as to face the upper surface of the case 315. The antenna 314 is provided on the second part 1170b.

[0175] Moreover, one side surface 317a of bulk feeder 317, which is a joining surface with one side surface 315b of case 315 on which tag 315t is provided, is provided at a position protruding from protective cover part 1170 in a plan view. For example, in a plan view, a portion of case 315 that does not overlap with second part 1170b has a larger area in a plan view than a portion that overlaps with second part 1170b. Also, for example, antenna 314 and tag 315t may be disposed at positions where they do not overlap each other in a plan view.

[0176] Fig. 14 is a perspective view showing a cart 1130 and its surroundings according to this embodiment. Note that Fig. 14 shows a view in which one bulk feeder 317 is attached.

[0177] 14, protective cover part 1170 has a plate-like portion extending along the X-axis direction, and is provided above case 315. Antenna 314 is disposed, for example, on the lower surface (surface on the negative Z-axis side) of protective cover part 1170.

[0178] Referring again to FIG. 13, the case 315 is provided on top of the bulk feeder 317 .

[0179] The antenna 314 is provided above the component supply unit 31. In this embodiment, the antenna 314 is attached to the protective cover part 1170. For example, no metallic member such as the bulk feeder 317 is disposed between the antenna 314 and the case 315. The antenna 314 is also connected to the RFID reading part 24 (see FIG. 8).

[0180] The antenna 314 is an antenna for communicating with the tags 315t, etc., in order to read information from the tags 315t, etc. One or more antennas 314 are provided. In this embodiment, a plurality of antennas 314 are provided. The arrangement interval between adjacent antennas 314 (corresponding to the arrangement interval P2 in the first embodiment) may be the same as the arrangement interval between the tags 315t (corresponding to the arrangement interval P1 in the first embodiment), or the arrangement interval between the antennas 314 may be greater. For example, the number of the one or more antennas 314 may be the same as the number of cases 315 that can be arranged in the component supply unit 31 (i.e., the number of bulk feeders 317), or may be less than the number of the cases 315.

[0181] A holding area (for example, holding area 70a shown in FIG. 2) for holding the tape cassette 60 may be provided below the component supply unit 31. The one or more antennas 314 may be configured to be able to communicate with a tag 615t of the tape cassette 60 held in the holding area. In other words, the tags 315t and 615t may each be able to communicate with the antenna 314 provided above.

[0182] Antenna 314 may also be capable of reading information from a tag provided on bulk feeder 317 instead of tag 315t on case 315 or in addition to tag 315t.

[0183] The operation (mounting support method) of the component mounting system including the component mounting apparatus 1020 according to the present embodiment may be the same as that of the component mounting apparatus 20 according to the first embodiment. For example, when the number of antennas 314 is the same as the number of cases 315, the position of the case 315 may be identified by the method shown in FIG. 11 of the first embodiment. For example, in the component mounting apparatus 1020, one or more antennas 314 are provided above the component supply unit 31, and the mounting support method may acquire the reception intensity of the radio wave received from the tag 315t by the one or more antennas 314 provided above the component supply unit 31, and identify the position of each object in a predetermined direction based on the acquired reception intensity of each object (for example, the case 315 or the bulk feeder 317).

[0184] (Modification of the second embodiment) The component mounting system according to this modification will be described below with reference to Fig. 15. Note that the following description will focus on the differences from the second embodiment, and descriptions of the same or similar contents as the second embodiment will be omitted or simplified.

[0185] FIG. 15 is a cross-sectional view that shows a schematic diagram of a carriage 1130a according to this modified example.

[0186] 15, the dolly 1130a may include a holder 1180 that holds the antenna 314. The holder 1180 holds the antenna 314 so that it can receive radio waves from the tag 315t from above the case 315. The holder 1180 holds the antenna 314 so that, for example, the antenna 314 and the case 315 at least partially overlap each other in a plan view.

[0187] In this manner, one or more antennas 314 are provided on the dolly 1130a. Also, the holder 1180 is provided on the dolly 1130a. Although not shown in Fig. 15, the dolly 1130a is provided with a fixing mechanism for fixing the holder 1180 to the main body of the dolly 1130a.

[0188] (Embodiment 3) When the number of feeders (e.g., cassette feeder 311 or bulk feeder 317) arranged in the component mounting device increases, the number of RFIDs to be read also increases and the width of the arrangement widens, the number of antennas needs to be increased because there is a restriction on the directivity of each antenna 314. However, there is a limit to the number of antennas that an RFID reading unit can have, and there are cases where the number of antennas cannot be increased. Even if the number of antennas can be increased, the cost increases.

[0189] Therefore, in this embodiment, a component mounting device is described that can detect all RFIDs, including the increased number of RFIDs to be read, without increasing the number of antennas (or with a smaller increase if the number of antennas is increased).

[0190] [3-1. Configuration of component mounting equipment] The configuration of a component mounting device according to the present embodiment will be described with reference to Fig. 16. The following description will focus on the differences from the first embodiment. The component mounting device according to the present embodiment includes an RFID reading unit 24a instead of the RFID reading unit 24 of the component mounting device 20 according to the first embodiment. Fig. 16 is a diagram showing the configuration of the RFID reading unit 24a according to the present embodiment.

[0191] The RFID reading unit 24a is a control device that has a circuit (e.g., radio circuit 1210) that generates a transmission signal for controlling the radio waves transmitted from the antenna 314, transmits the transmission signal that has passed through a phase shifter 1230 that adjusts the phase of the transmission signal to the multiple antennas 314, and transmits radio waves corresponding to the phase-controlled transmission signal from each of the multiple antennas 314. The RFID reading unit 24a changes the directivity of the radio waves (the direction in which the signal strength of the transmitted radio waves is strong) by, for example, individually controlling the phase of the radio waves transmitted from each antenna 314. This makes it possible to increase the signal strength of the signals received from the RFIDs arranged at both ends, for example, and therefore to expand the detection range of RFIDs without increasing the number of antennas 314.

[0192] As shown in FIG. 16, the RFID reader 24a includes a radio circuit 1210, a distribution circuit 1220, a phase shifter 1230, and a phase control circuit 1240.

[0193] The radio circuit 1210 is a circuit that generates a transmission signal (electrical signal) to be transmitted to the antenna 314. The radio circuit 1210 generates a transmission signal having a predetermined frequency and amplitude. Any known technology may be used to generate the transmission signal.

[0194] The distribution circuit 1220 distributes a signal input from an input terminal to each output terminal. The input terminal is electrically connected to the radio circuit 1210, and each output terminal is electrically connected to a different phase shifter 1230. The output terminal and the phase shifter 1230 are provided in a one-to-one correspondence. In this embodiment, the distribution circuit 1220 distributes the transmission signal generated by the radio circuit 1210 to each phase shifter 1230, and outputs a signal having a common intensity and phase.

[0195] The phase shifter 1230 is provided in a one-to-one correspondence with the antenna 314, and adjusts the phase of the signal acquired from the distribution circuit 1220 based on a control signal (e.g., first phase information and second phase information described below) from the phase control circuit 1240. The control signal (e.g., first phase information and second phase information) is information indicating the phase of the signal transmitted to the antenna 314 via the phase shifter 1230. The phase shifter 1230 has, for example, but is not limited to, a capacitor, an inductor (not shown) or the like for changing the phase of the signal passing therethrough.

[0196] The transmission signal that has passed through the phase shifter 1230, that is, the phase-controlled transmission signal, is transmitted from the RFID reading unit 24a to the antenna 314. The transmitted signal is output from each of the multiple antennas 314 simultaneously.

[0197] The phase control circuit 1240 outputs a control signal for controlling the phase of the transmission signal generated by the radio circuit 1210 to each phase shifter 1230. The phase control circuit 1240 makes the phase of the transmission signal different for each antenna 314, for example, based on information indicating the phase of the radio wave transmitted from each of the multiple antennas 314. The phase control circuit 1240 stores, for example, a table in which the phase of the radio wave transmitted from each of the multiple antennas 314 and the phase of the transmission signal are associated with each other, and generates and outputs a control signal based on the table. The phase control circuit 1240 generates, for example, first phase information indicating the phase of the transmission signal for each of the multiple antennas 314, and second phase information indicating the phase of the transmission signal for each of the multiple antennas 314, the second phase information being different from the first phase information. That is, the first phase information and the second phase information are information indicating a combination of phases of multiple transmission signals transmitted to the multiple antennas 314, and the phases of the multiple transmission signals are different from each other. It can be said that the phase control circuit 1240 generates, for example, first phase information and second phase information for making the directivities of the radio waves transmitted from the multiple antennas 314 different. The directivities of the radio waves transmitted from the multiple antennas 314 based on the first phase information and the directivities of the radio waves transmitted from the multiple antennas 314 based on the second phase information are different from each other. Different directions in which the signal strength is strong in the radio waves transmitted from the multiple antennas 314 are different are an example of different directivities of the radio waves. Each of includes information indicating the amount of adjustment of the phase of each of the multiple antennas 314. The amount of adjustment of the phase of each of the multiple antennas 314 may be different from each other.

[0198] The number of directions in which the signal strength of the transmitted radio wave is strong is not particularly limited as long as there are two or more directions. The directions in which the signal strength of the transmitted radio wave is strong may be set in advance, or may be adjusted each time based on the number of feeders used in the production and the feeder arrangement.

[0199] In this way, the RFID reader 24a is configured to be able to transmit, to each of the multiple antennas 314, a transmission signal whose phase has been adjusted based on the first phase information and the second phase information.

[0200] In addition, in this embodiment, the component mounting system includes a plurality of antennas 314 .

[0201] Here, the reception strength (RSSI) of radio waves from each antenna 314 when the radio wave directivity is changed will be described with reference to Figs. 17A and 17B. Fig. 17A is a diagram showing the reception strength distribution of radio waves from each antenna 314 when the beam is swung to the left in this embodiment. Fig. 17B is a diagram showing the reception strength distribution of radio waves from each antenna 314 when the beam is swung to the right in this embodiment 3. The beam means, for example, a direction in which the signal strength of the transmitted radio waves is strengthened. It is assumed that ant1, ant2, ant3, and ant4 are arranged in this order, and the RFIDs are arranged in the order of tag numbers 1 to 16, with the RFID with tag number 1 arranged on the ant1 side and the RFID with tag number 16 arranged on the ant4 side.

[0202] As shown in FIG. 17A, when the beam is directed to the left, the antennas 314, ant1 and 2, located on the left side, are unable to detect the RFIDs on the right side (e.g., RFIDs with tag numbers 11 to 15), but the antennas 314, ant3 and 4, located on the right side, are able to detect all of the RFIDs.

[0203] As shown in FIG. 17B, when the beam is directed to the right, the antennas 314, ant3 and ant4, located on the right side, are unable to detect the RFIDs on the left side (e.g., RFIDs with tag numbers 1 to 5), but the antennas 314, ant1 and ant2, located on the left side, are able to detect all of the RFIDs.

[0204] In addition, since the directivity of radio waves from the four antennas 314 is changed in two patterns, to the left and right, eight pieces of data can be obtained as reception intensity distribution. In other words, more reception intensity distribution data can be obtained compared to the case where the directivity of radio waves from the four antennas 314 is not changed (one pattern). Therefore, it is possible to increase the amount of learning data for training the machine learning model. It is possible to improve the accuracy of position determination of the machine learning model trained using such data.

[0205] The phase control circuit 1240 may change the directivity of the radio wave into three or more patterns. In this case, the phase control circuit 1240 generates phase information equal to the number of patterns.

[0206] [3-2. Operation of component mounting system] Next, the operation of the component mounting system configured as above will be described with reference to Fig. 18 and Fig. 19. Fig. 18 is a flow chart showing an example of the operation (mounting support method) of the component mounting system according to this embodiment. In Fig. 18, steps S110 to S130 are executed between steps S10 and S30.

[0207] As shown in FIG. 18, when tag detection is started (S10), the phase control circuit 1240 of the RFID reading unit 24a controls the phase of the transmission signal generated by the radio circuit 1210 (S110). The phase control circuit 1240 outputs a control signal to each phase shifter 1230, thereby changing the phase of the transmission signal in each phase shifter 1230. Specifically, the RFID reading unit 24a controls the phase for each antenna 314, and the phase-controlled transmission signal is transmitted to each antenna 314. Each antenna 314 simultaneously transmits radio waves (radio signals) based on the phase-controlled transmission signal according to the antenna 314, and receives radio waves (radio signals) transmitted from the tag 315t according to the radio waves. Here, it is assumed that the phase-controlled radio waves are transmitted based on the first phase information.

[0208] Next, the RFID reader 24a acquires the received signal strength (RSSI) for each antenna 314 from the received radio waves (S20).

[0209] Next, the RFID reader 24a judges whether RSSI has been acquired for all phase conditions (for example, the first phase information and the second phase information) (S130). If RSSI has been acquired for all phase conditions (Yes in S130), the RFID reader 24a proceeds to step S30, and if RSSI has not been acquired for all phase conditions (No in S130), the RFID reader 24a proceeds to step S110 and executes the processes of steps S110 to S130 for the remaining phase conditions. Here, since RSSI using the second phase information has not been acquired, No is judged in step S130, and RSSI is acquired using the second phase information.

[0210] In this way, the RFID reader 24a acquires the reception strength for each antenna 314 and each tag 315t according to the phase control conditions. For example, if there are three phase conditions, four antennas, and 15 tags, 180 reception strengths are acquired. The RFID reader 24a outputs the acquired reception strengths to the equipment controller 26 via the cart controller 25.

[0211] Next, the equipment control unit 26 uses the machine learning model to determine the tag position (S30). The equipment control unit 26 specifies the positions of the multiple feeders in the X-axis direction based on the wireless signals received from the tags 315t of the multiple feeders when the radio waves based on the first phase information are transmitted and the wireless signals received from the tags 315t of the multiple feeders when the radio waves based on the second phase information are transmitted. Specifically, the equipment control unit 26 inputs the signal strength (reception strength distribution) of the wireless signals received from the tags 315t of the multiple feeders when the radio waves based on the first phase information are transmitted and the signal strength (reception strength distribution) of the wireless signals received from the tags 315t of the multiple feeders when the radio waves based on the second phase information are transmitted to the machine learning model, and obtains the positions of the multiple feeders in the X-axis direction as the output.

[0212] The machine learning model used here is trained in advance by machine learning using the signal strength (reception strength distribution) of the wireless signal received from each tag 315t when the radio wave is transmitted from the multiple tags 315t based on the first phase information and the signal strength (reception strength distribution) of the wireless signal received from each tag 315t when the radio wave is transmitted from the multiple tags 315t based on the second phase information different from the first phase information as input data, and the positions of the multiple feeders in a predetermined direction at that time as correct answer data. The difference between the first phase information and the second phase information means that the phase adjustment amount is different. In other words, the directivity of the radio wave transmitted from the multiple antennas 314 based on the first phase information and the directivity of the radio wave transmitted from the multiple antennas 314 based on the second phase information are different from each other.

[0213] In the above, an example in which the RFID reading unit 24a controls the phase has been described, but the present invention is not limited to this. For example, a transmission signal may be supplied to an array antenna in which each antenna element has a phase controller, and the radio wave directivity of the radio waves transmitted by the array antenna may be changed. In this case, a common signal (common transmission signal) is transmitted from the RFID reading unit to each antenna. In addition, when the RFID reading unit does not control the phase, the component mounting device 20 may be provided with the RFID reading unit 24. In the following, the component mounting device 20 will be described as being provided with the RFID reading unit 24.

[0214] The array antenna has one input terminal and multiple output terminals. The input terminal is electrically connected to the RFID reader 24, and each output terminal is electrically connected to an input terminal of an antenna element corresponding to the output terminal. The output terminal and the input terminal of an antenna element (for example, a phase controller corresponding to the antenna element) are provided in a one-to-one correspondence. The antenna element is an example of an antenna.

[0215] The phase controller adjusts the phase of the acquired transmission signal. The phase controller has a configuration for changing the phase of the signal passing through. The phase controller controls the phase of the transmission signal based on third phase information generated by the RFID reading unit 24, which indicates the phase of the transmission signal for each antenna element, and fourth phase information, which indicates the phase of the transmission signal for each antenna element and is different from the third phase information. The phase controller and the antenna element are provided in a one-to-one correspondence.

[0216] The RFID reader 24 transmits the transmission signal to the array antenna, generates third phase information and fourth phase information, and transmits the generated third phase information and fourth phase information to the array antenna. Each of the third phase information and the fourth phase information includes information indicating the amount of phase adjustment of each of the multiple antenna elements. The amount of phase adjustment of each of the multiple antenna elements may be different from each other.

[0217] The operation of such a component mounting system equipped with an array antenna will be described with reference to Fig. 19. Fig. 19 is a flowchart showing another example of the operation (component mounting method) of the component mounting system according to this embodiment.

[0218] 19, when tag detection is started (S10), the phase controller controls the phase of the supplied transmission signal (S110a). The RFID reader 24 transmits radio waves for each antenna (for each antenna element) sequentially (or simultaneously) and receives radio waves (wireless signals) transmitted from the tag 315t in response to the radio waves. When transmitting radio waves sequentially, the order in which the radio waves are transmitted from the multiple antenna elements is not particularly limited.

[0219] Next, the RFID reader 24 acquires the reception strength (RSSI) of the antenna (antenna element) from the received radio wave (S120). The RFID reader 24 acquires the reception strength for each antenna (antenna element) and each tag 315t according to the phase control conditions. Here, it is assumed that the radio wave that is phase-controlled based on the third phase information is transmitted.

[0220] Next, the RFID reader 24 judges whether RSSI has been acquired for all phase conditions (S130). If RSSI has been acquired for all phase conditions (Yes in S130), the RFID reader 24a proceeds to step S30, and if RSSI has not been acquired for all phase conditions (No in S130), the RFID reader 24a proceeds to step S110a and executes the processes of steps S110a to S130 for the remaining phase conditions. Here, since RSSI using the fourth phase information has not been acquired, it is judged as No in step S130, and RSSI is acquired using the fourth phase information.

[0221] In this way, the RFID reader 24 acquires the reception strength for each antenna element and each tag 315t according to the phase control conditions. For example, if there are three phase conditions, four antenna elements, and 15 tags, 180 reception strengths are acquired. The RFID reader 24 outputs the acquired reception strengths to the equipment controller 26 via the cart controller 25.

[0222] Next, the equipment control unit 26 uses the machine learning model to determine the tag position (S30). The equipment control unit 26 specifies the positions of the multiple feeders in the X-axis direction based on the wireless signals received from the tags 315t of the multiple feeders when the radio waves based on the third phase information are transmitted and the wireless signals received from the tags 315t of the multiple feeders when the radio waves based on the fourth phase information are transmitted. Specifically, the equipment control unit 26 inputs the signal strength (reception strength distribution) of the wireless signals received from the tags 315t of the multiple feeders when the radio waves based on the third phase information are transmitted and the signal strength (reception strength distribution) of the wireless signals received from the tags 315t of the multiple feeders when the radio waves based on the fourth phase information are transmitted to the machine learning model, and obtains the positions of the multiple feeders in the X-axis direction as the output.

[0223] This makes it possible to expand the detection range in which the tag 315t can be detected in the component mounting device 20, and since data on the reception intensity distribution can be obtained by combining the number of antennas and phase control, the amount of reception intensity distribution data that can be used to train the machine learning model increases, thereby improving the accuracy of determining the position of the tag 315t using the machine learning model.

[0224] (Embodiment 4) [4-1. Configuration of mounting support device] A mounting support device that identifies the position of a feeder arranged in a placement section will be described with reference to Fig. 20 and Fig. 21. Fig. 20 is a block diagram showing a functional configuration of a mounting support device 1300 according to this embodiment.

[0225] 20, the mounting support apparatus 1300 includes an acquisition unit 1310, a processing unit 1320, and an output unit 1330. The mounting support apparatus 1300 may be realized, for example, by a server apparatus (i.e., an apparatus separate from the component mounting apparatus), or may be realized by the equipment control unit 26 shown in FIG. 8 (i.e., an apparatus built into the component mounting apparatus 20).

[0226] The acquiring unit 1310 is a communication interface that acquires data on the signal strength of a wireless signal received from the tag 315t of each of the multiple feeders. The acquiring unit 1310 acquires the signal strength data from, for example, the RFID reading unit 24 via communication. The acquiring unit 1310 is configured to include, for example, a communication circuit (or a communication module).

[0227] The processing unit 1320 executes the first process described above based on the signal intensity data acquired by the acquisition unit 1310. Specifically, the processing unit 1320 identifies the positions in the X-axis direction of the multiple feeders held in the holding area 70a or the like.

[0228] The output unit 1330 is a communication interface that outputs the result of the first processing by the processing unit 1320, that is, information indicating the positions of the multiple feeders in the X-axis direction. The output unit 1330 transmits the result of the first processing to an external device by communication, for example. The output unit 1330 is configured to include, for example, a communication circuit (or a communication module).

[0229] The mounting support device 1300 only needs to include at least the processing unit 1320 .

[0230] [4-2. Operation of mounting support device] Next, the operation of the mounting support apparatus 1300 configured as above will be described with reference to Fig. 21. Fig. 21 is a flowchart showing the operation (mounting support method) of the mounting support apparatus 1300 according to this embodiment.

[0231] 21, the acquisition unit 1310 acquires, via communication, RSSI (signal strength data) for each antenna 314 acquired by the RFID reading unit 24 (S210). The acquisition unit 1310 periodically acquires RSSI (signal strength data) for each antenna 314.

[0232] The process after step S30 is similar to the process after step S30 shown in FIG. 11, and therefore the description thereof will be omitted.
