[0012] (Background to this disclosure) The background to the present disclosure will be explained with reference to FIG.

[0013] FIG. 1 is a block diagram showing an RF tag reading system 101 of a comparative example.

[0014] An RF tag reading system 101 of the comparative example includes a reader / writer module 151 for acquiring information on an RF tag Tg, and a reading device 104 having a plurality of antennas A100 connected to the reader / writer module 151. For example, by incorporating this RF tag reading system 101 into a component supply device, it is possible to read RF tags Tg attached to containers 10 such as bulk cases via the antennas A100 and acquire information on the components stored in the containers 10. In the RF tag reading system 101 shown in FIG. 1 , the reader / writer module 151 is provided with 16 ports, and 16 antennas A100 are connected in one-to-one correspondence to the 16 ports. This RF tag reading system 101 can acquire information on the components stored in the 16 containers 10 via the 16 antennas A100.

[0015] However, in a mounting device that mounts many different types of components, for example, more than 100 types of components may be handled. Generally, the number of ports provided in a reader / writer module is limited, and it is difficult to increase the number of ports of the reader / writer module 151. Therefore, it is difficult for a component supply device equipped with the RF tag reading system 101 of the comparative example to manage the components supplied to the mounting device.

[0016] In contrast to this, the component supply system according to this embodiment has a configuration that can manage the components to be supplied to the mounting device.

[0017] Hereinafter, embodiments will be described with reference to the drawings. The embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection configurations, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components not described in independent claims will be described as optional components.

[0018] Furthermore, each figure is a schematic diagram and is not necessarily an exact illustration. Furthermore, in each figure, substantially the same configuration is given the same reference numeral, and duplicate explanations may be omitted or simplified. Furthermore, even when the same object is shown in each figure, the scale may be changed for convenience.

[0019] In this specification and drawings, the first and second directions are directions that are mutually orthogonal to the third direction. For example, if the feeder is elongated, the second direction is a direction parallel to the longitudinal direction of the feeder. The first direction is a direction parallel to the direction in which the feeders are arranged side by side.

[0020] Furthermore, in this specification, terms indicating the relationship between elements, such as coincidence, equality, and parallelism, terms indicating the shape of elements, such as plate-like and rectangular, as well as numerical values ​​and numerical ranges, are not expressions that only express the strict meaning, but are expressions that also include a substantially equivalent range, for example, a difference of about a few percent.

[0021] (Embodiment) [1. Configuration of parts supply system and reading device] First, the configuration of a component supply system according to an embodiment and a reading device included in the component supply system will be described.

[0022] FIG. 2 is a block diagram showing the component supply system 1 and the reading device 4 according to the embodiment.

[0023] The component supply system 1 according to the embodiment includes a control device 5 that controls the operation of the component supply system 1, and a plurality of reading devices 4 that are communicatively connected to the control device 5. Note that Fig. 2 also shows a component supply device 2 that the component supply system 1 includes. Fig. 2 also shows a feeder 20, a container 10, and RF tags Tg attached to the feeder 20 and the container 10. The RF tags Tg contain information about the components supplied by the component supply system 1.

[0024] Each reader 4 includes a substrate 40, a switching circuit 43 provided on the substrate 40, and a plurality of antennas AT formed on the substrate 40. The reader 4 is communicatively connected to a reader / writer module 51 included in the control device 5. Hereinafter, the reader / writer module 51 may be referred to as an RW module 51.

[0025] As shown in FIG. 2, the RW module 51 has multiple ports that are signal inlets and outlets. One switching circuit 43 is connected to each port. That is, multiple switching circuits 43 are connected to the multiple ports in a one-to-one relationship. Multiple antennas AT are connected to each switching circuit 43. FIG. 2 shows an example in which the control device 5 has one RW module 51 and the RW module 51 has 16 ports. Furthermore, 16 switching circuits 43 are connected to the 16 ports in a one-to-one relationship. Eight antennas AT are connected to each of the 16 switching circuits 43. In this way, the component supply system 1 can connect to 128 antennas AT from one RW module 51 via the 16 switching circuits 43. Using the 128 antennas, 128 RF tags Tg located around the reader 4 can be read.

[0026] Each of the components included in the component supply system 1 will be described below.

[0027] As described above, the control device 5 includes the RW module 51. The RW module 51 is a module that reads information stored in the RF tag Tg and writes information to be written to the RF tag Tg.

[0028] The RW module 51 has a radio wave control unit 52 and a power supply unit 53. The power supply unit 53 may be provided outside the RW module 51 and inside the control device 5.

[0029] The radio wave control unit 52 outputs a control signal that controls the radio waves radiated from the antenna AT. The control signal that controls this radio wave is, for example, a signal having an RFID modulated wave of 920 MHz. The radio wave control unit 52 also outputs a control signal that controls the on / off of the switching circuit 43 to switch the antenna AT that radiates the radio waves.

[0030] The power supply unit 53 supplies a direct current to the substrate 40 on which the multiple antennas AT are formed. This direct current is a current used to drive the switching circuit 43, which is an active element. These control signals and the direct current are output from the RW module 51 as a superimposed multiplexed signal.

[0031] The component supply system 1 further includes a plurality of transmission lines L1 that connect the control device 5 and the plurality of reading devices 4. Each transmission line L1 transmits the above-mentioned multiplexed signal to the board 40 of the reading device 4. Specifically, the transmission line L1 transmits the control signal output from the radio wave control unit 52 and supplies the DC current output from the power supply unit 53.

[0032] A coaxial cable is used as the wiring for the transmission line L1. Each port of the RW module 51 and the transmission line L1 are connected by a coaxial connector, such as an SMA (Sub Miniature Type A) connector. The multiplexed signal is transmitted through the central conductor of the coaxial cable. The ground of the coaxial cable is connected to the common ground of the control device 5 via a port of the RW module 51.

[0033] The control device 5 is placed at a position where the total length of the multiple transmission lines L1 is the shortest. In order to reduce variations in characteristics such as transmission loss, it is desirable that the multiple transmission lines L1 have the same length connecting the control device 5 and the substrate 40. In this case, the multiple transmission lines L1 having the same length means that the difference in length of the multiple transmission lines L1 is within ±10%.

[0034] Each reader 4 is connected to each transmission line L1. As described above, the reader 4 includes a substrate 40, a switching circuit 43 provided on the substrate 40, and a plurality of antennas AT formed on the substrate 40. The switching circuit 43 and the plurality of antennas AT are formed on the substrate 40. In FIG. 2, one switching circuit 43 and eight antennas AT are provided on the same substrate 40.

[0035] The switching circuit 43 is a circuit that switches the multiple antennas AT between a conductive state and a non-conductive state. For example, the conductive state is a state in which the antenna AT is conductive to the control device 5 (specifically, the corresponding port of the RW module 51) for reading the RF tag Tg. The non-conductive state is a state in which the antenna AT is not conductive to the control device 5 (specifically, the corresponding port of the RW module 51) for reading the RF tag Tg.

[0036] 2 is a SPmT (single-pole, multi-throw) switch, and has one common terminal and eight selection terminals. The switching circuit 43 selectively connects eight antennas AT to one transmission line L1, i.e., one port of the RW module 51. The switching circuit 43 switches the connection destination of the eight antennas AT based on a control signal output from the RW module 51, and outputs an RFID modulated wave to the connected antenna AT. The switching circuit 43 may also have a function of performing serial-to-parallel conversion on the signal output from the RW module 51.

[0037] The multiple antennas AT are antennas that receive signals from the RF tag Tg. For example, when reading the RF tag Tg, the antennas AT emit radio waves based on a control signal and receive a signal returned from the RFID chip having the RF tag Tg. The received signal is transmitted to the RW module 51 via the switching circuit 43 and the transmission line L1. This enables the RW module 51 to read the RF tag Tg and obtain the EPC (Electronic Product Code) code and user data stored in the memory of the RFID chip having the RF tag Tg, as well as information about the components supplied by the feeder 20 and the components contained in the container 10.

[0038] In this way, the component supply system 1 includes a plurality of antennas AT provided corresponding to a plurality of feeders 20, and at least one substrate 40 on which a plurality of antennas AT are formed, in order to read the RF tags Tg. This component supply system 1 can read a plurality of RF tags Tg attached to a plurality of feeders 20 and a plurality of containers 10. This makes it possible to manage the components supplied to the mounting device.

[0039] The substrate 40 is also provided with a switching circuit 43 that switches the multiple antennas AT between a conductive state and a non-conductive state. According to this component supply system 1, it is possible to read multiple RF tags Tg by switching the antenna AT for reading RF tags Tg. This makes it possible to manage the components supplied to the mounting device.

[0040] [2. Overall configuration of the mounted system] Next, the overall configuration of the mounting system 9 including the component supply system 1 will be described.

[0041] FIG. 3 is a schematic diagram showing a mounting system 9 including the component supply system 1. As shown in FIG.

[0042] Mounting system 9 includes a control device 5, a transport robot 60, a plurality of component supply devices 2, and a mounting line 90 consisting of a plurality of mounting devices 7. Mounting system 9 also includes three areas: a storage area 91, a preparation area 92, and a mounting area 93. Component supply system 1 is made up of a plurality of component supply devices 2 and control device 5.

[0043] The mounting area 93 is an area where the mounting line 90 is located. The mounting line 90 produces mounted boards by mounting components onto printed circuit boards carried in from the upstream side, and carries out the produced mounted boards downstream. The mounting line 90 is realized by various devices that perform operations such as supplying printed circuit boards, solder printing, component mounting, and reflow. The component mounting operation is performed by a mounting device 7.

[0044] The component supplying device 2 is a device that supplies components to the mounting device 7. The component supplying device 2 includes, for example, a feeder arrangement unit 30 that is movable by a cart, a feeder 20 held by the feeder arrangement unit 30, and a container 10 connected to the feeder 20. The feeder 20 is made up of a feeder main body unit 21 and an attachment 22 attached to the feeder main body unit 21. The component supplying device 2 will be described in detail later.

[0045] The storage area 91 is an area for storing the component containers 10 and the attachments 22 of the feeders 20. The preparation area 92 is an area for preparing items to be used on the mounting line 90 in the mounting area 93 in advance.

[0046] The control device 5 controls production on the mounting line 90 based on, for example, a production plan. When the remaining number of components in the container 10 attached to the component supply device 2 falls below a predetermined number, the control device 5 controls the transfer robot 60 to replace the container 10 of the component supply device 2 with a new container 10. Furthermore, when the container 10 attached to the component supply device 2 is to be changed to a container 10 containing a different type of component, the control device 5 controls the transfer robot 60 to replace the container 10 and attachment 22 of the component supply device 2. In this way, the control device 5 manages the supply of components and the change of component types in the mounting system 9.

[0047] [3. Configuration of parts supply device] Next, the configuration of the component supply device 2 included in the component supply system 1 will be described with reference to Figures 4 to 7. Here, the detailed configuration of the reading device 4 will also be described at the same time as the component supply device 2 is described.

[0048] Fig. 4 is a side view of the feeder arrangement section 30 of the component supplying device 2. Fig. 5 is a top view of the feeder arrangement section 30 of the component supplying device 2. Fig. 6 is a front view of a portion of the feeder arrangement section 30 of the component supplying device 2.

[0049] 4 and 5, the component supply device 2 has a plurality of feeders 20 and a feeder arrangement section 30 in which the plurality of feeders 20 are arranged. The above-mentioned board 40 is provided inside the feeder arrangement section 30.

[0050] A container 10 containing components is connected to each of the multiple feeders 20. The feeders 20 take out the components contained in the containers 10 and supply them to the mounting device 7. The mounting device 7 handles the components supplied from the feeders 20 and mounts them on a printed circuit board.

[0051] The components are components for mounting on a printed circuit board, such as, but not limited to, electronic components such as resistors and capacitors, as long as they can be mounted on a printed circuit board.

[0052] The containers 10 are containers for storing components, such as bulk cases for storing chip components in a bulk state and taping cases for storing component-attached carrier tapes. The containers 10 are detachable from the feeder 20. An RF tag Tg equipped with an RFID chip cp is attached to each container 10. The RF tag Tg contains information about the components stored in the container 10, such as an EPC (Electronic Product Code) code and user data stored in the memory of the RFID chip having the RF tag Tg, or information indicating the type of component (identification information), information indicating the quantity (remaining number), and information indicating the expiration date.

[0053] Feeder 20 is a device that conveys parts by, for example, vibration or an intermittent feeding mechanism. Note that feeder 20 may also convey parts by, for example, air supply, magnetic force, conveyor, etc. An RF tag Tg equipped with an RFID chip cp is affixed to attachment 22 or feeder main body 21 of feeder 20. This RF tag Tg contains information about parts that can be supplied by feeder 20. This RF tag Tg may also contain information such as identification information and usage history of feeder 20.

[0054] FIG. 5 shows an example in which two component supply devices 2 are connected to one mounting device 7 on both sides. Here, the description focuses on one component supply device 2. As shown in FIG. 5, multiple feeders 20 arranged in the feeder arrangement section 30 are aligned along a first direction d1. Each feeder 20 transports and supplies components, for example, along a second direction d2 that is perpendicular to the first direction d1 in which the feeders 20 are aligned. The second direction d2 is a direction that runs along the main surface of the substrate 40 and is perpendicular to the first direction d1.

[0055] As shown in FIG. 6 , the feeder arrangement section 30 has a plurality of slots 31. The slots 31 are attachment openings for attaching the feeders 20 to the feeder arrangement section 30, and are provided in the upper region of the feeder arrangement section 30. The slots 31 are openings such as holes, grooves, or recesses. The outer frame of the feeder 20, or round pins, square pins, or the like provided on the feeder 20 are fitted into the slots 31 to position the feeder 20. The feeder 20 is detachable from the slots 31. The plurality of feeders 20 are attached to the plurality of slots 31 in a one-to-one correspondence.

[0056] 4 and 5, a substrate 40 is provided inside the feeder arrangement section 30 along the horizontal direction. That is, the substrate 40 is arranged along both the first direction d1 and the second direction d2 and perpendicular to the third direction d3, which is the vertical direction. Note that the substrate 40 is not limited to being arranged horizontally, and may be arranged inside the feeder arrangement section 30 at an angle or along the vertical direction.

[0057] A plurality of antennas AT are formed on each of the plurality of substrates 40. As shown in Fig. 5, a shielding member s1 (indicated by a thick dashed line in Fig. 5) is provided between the plurality of substrates 40 to suppress radio wave interference with the antenna AT of an adjacent substrate 40. The shielding member s1 is, for example, a metal plate or a metal mesh, and is provided within the feeder arrangement section 30. Note that Fig. 5 shows an example in which two substrates 40 are provided within the feeder arrangement section 30, but this is not limiting. A single substrate 40 may be provided in the feeder arrangement section 30, and two switching circuits 43 and 16 antennas AT may be provided on the single substrate 40.

[0058] The multiple antennas AT are provided corresponding to the multiple slots 31. Specifically, the multiple antennas AT are provided in one-to-one correspondence with the multiple slots 31. The antenna AT is an antenna for reading an RF tag Tg attached to at least one of the feeder 20 arranged in the slot 31 and the container 10 connected to the feeder 20. The antenna AT is provided at a position overlapping the RF tag Tg when viewed from a direction perpendicular to the substrate 40, i.e., the third direction d3 (see FIG. 5).

[0059] Fig. 7 is a diagram showing an example of an antenna AT provided in the component supply system 1. Fig. 7(a) is a plan view, and Fig. 7(b) is a view seen from the front.

[0060] Each of the multiple antennas AT is, for example, a meandering antenna. Specifically, each of the multiple antennas AT has a square wave shape, with the first direction d1 being the amplitude direction of the square wave and the second direction d2 being the period (pitch) of the square wave, and extends along the second direction d2 with the same repeating period. Furthermore, of the multiple antennas AT, two antennas adjacent to each other in the first direction d1 have the same antenna shape and the same repeating period of the square wave shape. By having the above-mentioned shape of the antenna AT, radio waves with high electric field strength are emitted in a third direction d3 perpendicular to the substrate 40.

[0061] The antenna AT is arranged so that the surface ats of the antenna area including the antenna AT formed on the substrate 40 faces the surface of the RF tag Tg. Furthermore, the antenna AT is arranged so that the electric field direction of the antenna AT, which is the same direction as the extension direction of the antenna AT, coincides with the electric field direction of the RF tag Tg. Note that the axis along the electric field direction of the antenna AT is included within the surface ats of the antenna area, and the axis along the electric field direction of the RF tag Tg is included within the surface of the RF tag Tg.

[0062] As shown in FIG. 7, the substrate 40 is provided with lands 41, a first relay line 42, a switching circuit 43, a plurality of second relay lines 44, a plurality of lead wires 45, a plurality of ground planes 46, and a plurality of antennas AT.

[0063] In this embodiment, the reader 4 is made up of a substrate 40, a land 41, a first relay line 42, a switching circuit 43, a plurality of second relay lines 44, a plurality of lead-out wirings 45, a plurality of ground planes 46, and a plurality of antennas AT. The land 41, the first relay line 42, the switching circuit 43, the plurality of second relay lines 44, the plurality of lead-out wirings 45, the plurality of ground planes 46, and the plurality of antennas AT are provided on the same surface of the substrate 40. The land 41, the lead-out wirings 45, the ground plane 46, and the antennas AT are made of the same electrode material and have the same thickness.

[0064] The land 41 is a signal inlet / outlet and is provided at one end of the substrate 40 in the second direction d2. The land 41 is connected to a transmission line L1 made up of a single coaxial cable. The multiplexed signal output from the RW module 51 is input to the land 41. The transmission line L1 and the land 41 may be connected via a coaxial connector.

[0065] The switching circuit 43 is provided on a path connecting the land 41 and the plurality of antennas AT. The switching circuit 43 is also disposed at a position including the center atc of the plurality of antennas AT when viewed from the second direction d2 (see (b) of FIG. 7).

[0066] The land 41 and the switching circuit 43 are connected by a first relay line 42. The multiplexed signal output from the land 41 is transmitted to the first relay line 42. The first relay line 42 is, for example, a wiring pattern formed on the substrate 40, but may also be a coaxial cable.

[0067] The switching circuit 43 and the antenna AT are connected by a second relay line 44 and an outgoing wiring 45. The second relay line 44 is a wiring that connects the switching circuit 43 and the outgoing wiring 45. The second relay line 44 is, for example, a wiring pattern formed on the substrate 40, but may be a coaxial cable. The outgoing wiring 45 is a wiring pattern that connects the second relay line 44 and the antenna AT. The outgoing wiring 45 is a wiring pattern formed on the substrate 40. The outgoing wiring 45 is provided along the second direction d2 and is connected to one end of the antenna AT.

[0068] The ground plane 46 extends in the second direction d2 along the lead-out wiring 45. The ground plane 46 is not in contact with the lead-out wiring 45, but is formed at a distance from the lead-out wiring 45. The ground plane 46 is also formed between the plurality of lead-out wirings 45. In other words, the ground plane 46 and the lead-out wiring 45 are alternately arranged along the first direction d1. The ground plane 46 is connected to the ground of the coaxial cable via a jumper wire or a back surface wiring and a through-hole wiring.

[0069] The antennas AT are formed so as to extend along the second direction d2 as described above. An extraction wiring 45 is connected to one end of each of the antennas AT.

[0070] In this embodiment, the switching operation of the switching circuit 43 switches between a non-conductive state and a conductive state between the multiple antennas AT and the lands 41. Specifically, the switching circuit 43 operates in response to a control signal included in the multiplexed signal transmitted from the RW module 51, and the connected antennas AT are sequentially switched. For example, when one antenna AT is in a conductive state, the other antennas AT are in a non-conductive state. The RW module 51 communicates with the RFID chip cp by emitting an RFID modulated wave from the antenna AT in a conductive state, and acquires the information contained in the RFID chip cp.

[0071] In the above example, two antennas adjacent to each other in the first direction d1 have the same antenna shape and the same square wave repeat period, but the antenna shape is not limited to this.

[0072] Figures 8 and 9 are diagrams showing another example of the antenna AT shown in Figure 7. In Figures 8 and 9, the line of the antenna AT is shown by a solid line.

[0073] Fig. 8 shows an antenna AT in which the repetition periods of the square waves in the second direction d2 are shifted by 1 / 2 period. In this way, two antennas adjacent to each other in the first direction d1 may be arranged with their positions shifted from each other in the second direction d2 that is perpendicular to the first direction d1 and along the substrate 40. Fig. 9 shows an antenna AT with a shape that is mirror-reversed from the left to right. In this way, two antennas adjacent to each other in the first direction d1 may have different antenna shapes.

[0074] [4. Effects etc.] As described above, the component supply system 1 according to this embodiment comprises a plurality of feeders 20 that supply components stored in a container 10 to a mounting device 7, a feeder arrangement section 30 having a plurality of slots 31 in which each of the plurality of feeders 20 is arranged, a plurality of antennas AT provided corresponding to the plurality of slots 31 for reading RF tags Tg attached to at least one of the feeders 20 arranged in the slots 31 and the containers 10 connected to the feeders 20, and at least one substrate 40 on which the plurality of antennas AT are formed.

[0075] According to this component supply system 1, it is possible to read a plurality of RF tags Tg attached to a plurality of feeders 20 and a plurality of containers 10. This makes it possible to manage the components to be supplied to the mounting device 7.

[0076] Furthermore, the plurality of antennas AT may be provided in one-to-one correspondence with the plurality of slots 31.

[0077] This makes it possible to read the RF tags Tg of the feeders 20 or containers 10 arranged in the slots 31 in a one-to-one correspondence, thereby making it possible to manage the components supplied to the mounting device 7.

[0078] Furthermore, the substrate 40 may be provided inside the feeder arrangement section 30, and the antenna AT may be arranged so that the surface ats of the antenna area including the antenna AT formed on the substrate 40 faces the surface of the RF tag Tg.

[0079] This allows the RF tag Tg to be properly read using the antenna AT, thereby enabling the components supplied to the mounting device 7 to be managed.

[0080] Furthermore, each of the multiple antennas AT may have a square wave shape and extend in a second direction d2 that is along the substrate 40 and perpendicular to the first direction d1 in which the multiple feeders 20 are arranged.

[0081] According to this configuration, the antenna AT can emit radio waves with high electric field strength in a direction perpendicular to the substrate 40. Therefore, the RF tag Tg can be properly read using the antenna AT. This allows the components supplied to the mounting device 7 to be managed.

[0082] In addition, the multiple antennas AT are arranged side by side along a first direction d1 in which the multiple feeders 20 are arranged, and among the multiple antennas AT, two antennas adjacent to each other in the first direction d1 may be positioned offset from each other in a second direction d2 that is a direction along the substrate 40 and perpendicular to the first direction d1.

[0083] This configuration can prevent the antenna AT from emitting radio waves from coupling with other antennas AT located nearby. This allows the antenna AT to properly read the RF tag Tg. This allows the parts supplied to the mounting device 7 to be managed.

[0084] In addition, the multiple antennas AT are arranged side by side along the first direction d1 in which the multiple feeders 20 are arranged, and among the multiple antennas AT, two antennas adjacent to each other in the first direction d1 may have different antenna shapes.

[0085] This configuration can prevent the antenna AT from emitting radio waves from coupling with other antennas AT located nearby. This allows the antenna AT to properly read the RF tag Tg. This allows the parts supplied to the mounting device 7 to be managed.

[0086] The substrate 40 may also be provided with a switching circuit 43 that switches the plurality of antennas AT between a conductive state and a non-conductive state.

[0087] This makes it possible to read a plurality of RF tags Tg by switching the antenna AT using the switching circuit 43. This makes it possible to manage the components supplied to the mounting device 7.

[0088] In addition, the multiple antennas AT may be arranged side by side along a first direction d1 in which the multiple feeders 20 are arranged, and the switching circuit 43 may be positioned at a position including the center atc of the multiple antennas AT when viewed from a second direction d2 that is along the substrate 40 and perpendicular to the first direction d1.

[0089] This reduces the variation in the distance connecting the switching circuit 43 and the multiple antennas AT, thereby reducing the variation in characteristics such as transmission loss. Therefore, the RF tag Tg can be properly read using the antenna AT. This makes it possible to manage the parts supplied to the mounting device 7.

[0090] Furthermore, the component supply system 1 may have a plurality of boards 40, and a shielding member s1 may be provided between the plurality of boards 40 to block radio waves emitted from the plurality of antennas AT.

[0091] This makes it possible to prevent multiple antennas AT from interfering with multiple antennas AT on adjacent boards. Therefore, the RF tags Tg can be properly read using the antennas AT. This makes it possible to manage the components supplied to the mounting device 7.

[0092] In addition, the parts supply system 1 further includes a control device 5 having a radio wave control unit 52 that outputs control signals to control radio waves emitted from the multiple antennas AT, and a power supply unit 53 that supplies direct current to a substrate 40 on which the multiple antennas AT are formed, and a transmission line L1 that connects the substrate 40 and the control device 5, and the transmission line L1 may transmit the control signal output from the radio wave control unit 52 and supply the direct current output from the power supply unit 53.

[0093] In this way, by transmitting control signals and supplying DC current using the transmission line L1, it is possible to switch the radio waves emitted from the multiple antennas AT and read multiple RF tags Tg, thereby making it possible to manage the components supplied to the mounting device 7.

[0094] Furthermore, the component supply system 1 has a plurality of substrates 40 and a plurality of transmission lines L1 corresponding one-to-one to the plurality of substrates 40, and the plurality of transmission lines L1 may have the same length.

[0095] This reduces the variation in characteristics such as transmission loss among the multiple transmission paths L1. Therefore, the RF tag Tg can be properly read using the antenna AT. This allows the parts supplied to the mounting device 7 to be managed.

[0096] The component supply system 1 of this embodiment also includes a plurality of feeders 20 that supply components stored in the container 10 to the mounting device 7, a feeder arrangement section 30 having a plurality of slots 31 in which each of the plurality of feeders 20 is arranged, a plurality of antennas AT provided corresponding to the plurality of slots 31 in order to read the RF tags Tg attached to at least one of the feeders 20 arranged in the slots 31 and the container 10 connected to the feeders 20, and a switching circuit 43 provided in the feeder arrangement section 30 and switching the plurality of antennas AT between a conductive state and a non-conductive state.

[0097] This makes it possible to read a plurality of RF tags Tg by switching the antenna AT using the switching circuit 43. This makes it possible to manage the components supplied to the mounting device 7.

[0098] The reading device 4 of this embodiment includes a plurality of antennas AT corresponding to the plurality of feeders 20 that supply components to the mounting device 7, and at least one substrate 40 on which the plurality of antennas AT are formed, in order to read RF tags Tg attached to at least one of the plurality of feeders 20 that supply components to the mounting device 7 and the component containers (containers 10) connected to the feeders 20.

[0099] This reading device 4 can read a plurality of RF tags Tg attached to a plurality of feeders 20 and component containers, thereby enabling management of components supplied to the mounting device 7.

[0100] The substrate 40 may also be provided with a switching circuit 43 that switches the plurality of antennas AT between a conductive state and a non-conductive state.

[0101] This makes it possible to read a plurality of RF tags Tg by switching the antenna AT using the switching circuit 43. This makes it possible to manage the components supplied to the mounting device 7.

[0102] [5. Variation 1 of the reading device] A reader 4A according to Modification 1 of the embodiment will be described below. In Modification 1, an example will be described in which the reader 4A has a plurality of ground electrodes 47A.

[0103] 10 is a diagram schematically showing a part of a reading device 4A according to Modification 1. In FIG. 10, (a) is a plan view, and (b) is a cross-sectional view taken along line Xb-Xb shown in (a).

[0104] The reader 4A of the first modification includes a substrate 40, a land 41, a switching circuit 43, a first relay line 42, a plurality of second relay lines 44, a plurality of lead-out wirings 45, a plurality of ground planes 46, a plurality of antennas AT, and a plurality of ground electrodes 47A. Note that only the substrate 40, the antenna AT, and the ground electrode 47A are shown in FIG.

[0105] Each of the multiple antennas AT is a meandering antenna, and is formed on the substrate 40 so as to extend in the second direction d2.

[0106] Each of the multiple ground electrodes 47A extends linearly in the second direction d2 along the antenna AT. The length of the ground electrode 47A in the second direction d2 is the same as the length of the antenna AT. The ground electrode 47A is not in contact with the antenna AT and is spaced apart from the antenna AT. The ground electrode 47A is also provided between the multiple antennas AT in the first direction d1. The ground electrode 47A and the antenna AT are made of the same electrode material and have the same thickness. The ground electrode 47A may be thicker than the antenna AT. The ground electrode 47A is connected to the ground of the coaxial cable via a jumper wire or a back surface wiring and a through-hole wiring.

[0107] In the reader 4A of the first modification, a ground electrode 47A connected to the ground is formed on the substrate 40, and the ground electrode 47A is disposed between adjacent antennas among the plurality of antennas AT.

[0108] In this way, by providing the reading device 4A with the above-mentioned ground electrode 47A, the antenna AT that receives the signal from the RF tag Tg can be prevented from receiving the signal from the RF tag Tg located next to the RF tag Tg. This prevents false detection and makes it possible to obtain information only about the components to be supplied. This makes it possible to manage the components to be supplied to the mounting device 7. Furthermore, since reading of adjacent RF tags Tg is prevented, the transmission output of the RW module 51 can be increased accordingly, which is advantageous for obtaining information about the components to be supplied.

[0109] [6. Variation 2 of the reading device] A reader 4B according to Modification 2 of the embodiment will be described below. In Modification 2, an example will be described in which the reader 4B has ground electrodes 47B that are connected to each other.

[0110] 11 is a diagram schematically showing a part of a reading device 4B according to Modification 2. In FIG. 11, (a) is a plan view, and (b) is a cross-sectional view taken along line XIb-XIb shown in (a).

[0111] The reader 4B of the second modification includes a substrate 40, a land 41, a switching circuit 43, a first relay line 42, a plurality of second relay lines 44, a plurality of lead-out wirings 45, a plurality of ground planes 46, and a plurality of antennas AT, and further includes a ground electrode 47B. Note that only the substrate 40, the antenna AT, and the ground electrode 47B are shown in FIG.

[0112] Each of the multiple antennas AT is a meandering antenna, and is formed on the substrate 40 so as to extend in the second direction d2.

[0113] The ground electrode 47B has a comb-like shape and includes a linear portion extending linearly in the second direction d2 along the antenna AT. The length of the linear portion of the ground electrode 47B in the second direction d2 is longer than the length of the antenna AT. The linear portions of the ground electrodes 47B are connected to each other on the opposite side of the land 41 in the second direction d2, i.e., on the other end side of the substrate 40. The ground electrodes 47B do not contact the antenna AT but are spaced apart from the antenna AT. The linear portions of the ground electrodes 47B are also provided between and outside the multiple antennas AT in the first direction d1. That is, the antenna AT is provided between two adjacent linear portions of the ground electrodes 47B. The ground electrode 47B and the antenna AT are made of the same electrode material and have the same thickness. The ground electrode 47B may be thicker than the antenna AT. The ground electrode 47B is connected to the ground of the coaxial cable via a jumper wire, a back surface wiring, or a through-hole wiring.

[0114] In the reader 4B of the second modification, a ground electrode 47B connected to the ground is formed on the substrate 40, and the ground electrode 47B is disposed between adjacent antennas among the plurality of antennas AT.

[0115] In this way, by providing the reading device 4B with the above-mentioned ground electrode 47B, the antenna AT that receives the signal from the RF tag Tg can be prevented from receiving the signal from the RF tag Tg located next to the RF tag Tg. This prevents false detection and makes it possible to obtain information only about the components to be supplied. This makes it possible to manage the components to be supplied to the mounting device 7. Furthermore, since reading of adjacent RF tags Tg is prevented, the transmission output of the RW module 51 can be increased accordingly, which is advantageous for obtaining information about the components to be supplied.

[0116] [7. Variation 3 of the reading device] A reader 4C according to a third modification of the embodiment will be described below. In the third modification, a ground electrode 47C includes a through-hole electrode.

[0117] Fig. 12 is a diagram schematically illustrating a part of a reading device 4C according to Modification 3 of the embodiment, in which (a) is a plan view, (b) is a cross-sectional view taken along line XIIb-XIIb shown in (a), and (c) is a bottom view.

[0118] The reader 4C of the third modification includes a substrate 40, a land 41, a switching circuit 43, a first relay line 42, a plurality of second relay lines 44, a plurality of lead-out wirings 45, a plurality of ground planes 46, and a plurality of antennas AT, and further includes a ground electrode 47C. Note that only the substrate 40, the antenna AT, and the ground electrode 47C are shown in FIG.

[0119] Each of the multiple antennas AT is a meandering antenna, and is formed on the substrate 40 so as to extend in the second direction d2.

[0120] The ground electrode 47C is composed of a plate-shaped first ground electrode 47Ca formed on the back side of the substrate 40 and multiple second ground electrodes 47Cb, which are through-hole electrodes. The second ground electrode 47Cb is electrically connected to the first ground electrode 47Ca. The multiple second ground electrodes 47Cb are formed at equal intervals along the antenna AT, i.e., along the second direction d2. The second ground electrode 47Cb is not in contact with the antenna AT but is spaced apart from the antenna AT. The second ground electrode 47Cb is also provided between the multiple antennas AT in the first direction d1. The first ground electrode 47Ca on the back side is connected to the ground of the coaxial cable via a jumper wire or back wiring and through-hole wiring.

[0121] In a reader 4C of the third modification, a ground electrode 47Cb connected to the ground is formed on the substrate 40, and the ground electrode 47Cb is disposed between adjacent antennas among the plurality of antennas AT.

[0122] In this way, by providing the reading device 4C with the ground electrode 47Cb, the antenna AT that receives the signal from the RF tag Tg can be prevented from receiving the signal from the RF tag Tg located next to the RF tag Tg. This prevents false detection and makes it possible to obtain information only about the components to be supplied. This allows for management of the components to be supplied to the mounting device 7. Furthermore, since reading of adjacent RF tags Tg is prevented, the transmission output of the RW module 51 can be increased, which is advantageous for obtaining information about the components to be supplied.

[0123] [8. Variation 4 of the reading device] A reader 4D according to a fourth modification of the embodiment will be described below. In the fourth modification, a switching circuit 43 and an antenna AT are formed on separate substrates 40A and 40B.

[0124] FIG. 13 is a diagram showing a reading device 4D according to the fourth modification.

[0125] A reader 4D of the fourth modification example is composed of a substrate 40A, a substrate 40B, a land 41, a first relay line 42, a switching circuit 43, a plurality of second relay lines 44a and 44b, a plurality of lead-out wirings 45, a plurality of ground planes 46, and a plurality of antennas AT. The land 41, the first relay line 42, the switching circuit 43, and the plurality of second relay lines 44a are provided on the same surface of the substrate 40A. The plurality of second relay lines 44b, the plurality of lead-out wirings 45, the plurality of ground planes 46, and the plurality of antennas AT are provided on the same surface of the substrate 40B.

[0126] The second relay line 44a and the second relay line 44b are connected by a coaxial cable. Specifically, the second relay line 44a is connected to one coaxial connector provided on the substrate 40A, and the second relay line 44b is connected to the other coaxial connector provided on the substrate 40B, and the one coaxial connector and the other coaxial connector are connected by a coaxial cable.

[0127] According to the reader 4D of the fourth modification, for example, it is possible to change the antenna AT depending on the frequency used by the RF tag Tg, thereby improving the versatility of the reader 4D. This makes it possible to manage a wide range of components supplied to the mounting device 7.

[0128] [9. Variation 5 of the Reading Device] A reader 4E according to a fifth modification of the embodiment will be described. In the fifth modification, a switching circuit 43 is formed on a substrate 40A, and a plurality of antennas AT are formed separately on a plurality of substrates 40C.

[0129] FIG. 14 is a diagram showing a reading device 4E according to the fifth modification.

[0130] The reader 4E of the fifth modification example is composed of a substrate 40A, multiple substrates 40C, a land 41, a first relay line 42, a switching circuit 43, multiple second relay lines 44a and 44b, multiple lead-out wirings 45, multiple ground planes 46, and multiple antennas AT. The land 41, the first relay line 42, the switching circuit 43, and the multiple second relay lines 44a are provided on the same surface of the substrate 40A.

[0131] In addition, in the reader 4E of the fifth modification, a plurality of antennas AT are formed separately on a plurality of substrates 40C. Specifically, one antenna AT, one second relay line 44b, one lead-out wiring 45, and one ground plane 46 are provided on the same surface of one substrate 40C.

[0132] The second relay line 44a and the second relay line 44b are connected by a coaxial cable. Specifically, the second relay line 44a is connected to one coaxial connector provided on the substrate 40A, and the second relay line 44b is connected to the other coaxial connector provided on the substrate 40C, and the one coaxial connector and the other coaxial connector are connected by a coaxial cable.

[0133] According to the reader 4E of the fifth modification, for example, it is possible to individually change the antenna AT depending on the frequency used by the RF tag Tg, and the versatility of the reader 4E can be further improved. This makes it possible to manage a wide range of components supplied to the mounting device 7.

[0134] [10. Modified parts supply system] A modified example of the component supply system 1 according to the embodiment will be described.

[0135] FIG. 15 is a block diagram showing a modified example of the component supply system 1. In FIG.

[0136] In the modified component supply system 1, the control device 5 and the board 40 are connected not only by the transmission path L1 but also by a harness, which is another path. For example, in the modified component supply system 1, a control signal output from the control device 5 is input to each switching circuit 43 via the harness. This control signal may be a control signal that controls radio waves radiated from the antenna AT, or a control signal that controls the on / off of the switching circuit 43. Note that the control device 5 may output a direct current that drives the switching circuit 43 via the harness instead of outputting the above control signal.

[0137] The component supply system 1 of this modified example can also achieve the same effects as those of the component supply system 1 of the embodiment.
