In the mounting process, the component mounter 10 sends a control signal to the head driving device 13 based on the results of image processing, the results of detection by various sensors, pre-stored control programs, and the like. Thereby, the positions and angles of a plurality of holding members (for example, suction nozzles) supported by the mounting head 30 are controlled.

A holding member (for example, a suction nozzle) held by the mounting head 30 can be appropriately changed according to the type of component to be mounted on the substrate 90 in the mounting process. For example, when the mounting head 30 does not hold the suction nozzle used in the mounting process to be executed, the component mounting machine 10 causes the mounting head 30 to hold the suction nozzle housed in the nozzle station. The nozzle station is detachably installed at a predetermined position inside the component mounting machine 10 .

In the power transmission circuit PT0, a power supply unit PU1, a switch SW1, a power transmission side resonance unit RT1, and a power transmission unit 45 are connected in series to form a power transmission side resonance circuit. The power supply unit PU1 is provided in the power supply circuit PC0 of the component mounting machine 10 described above, and generates AC power. For example, a normally open switch can be used as the switch SW1. A capacitor can be used for the power transmission side resonance unit RT1. A coil can be used for the power transmission unit 45 .

When the supply control unit 61 switches the switch SW1 from the open state to the closed state, the power transmission circuit PT0 is closed and AC power is supplied to the power reception circuit PR0 provided in the unit 70 . Conversely, when the supply control unit 61 switches the switch SW1 from the closed state to the open state, the power transmission circuit PT0 is opened and the supply of AC power to the power reception circuit PR0 is stopped.

In the power receiving circuit PR0, the unit side power receiving portion 72 and the power receiving side resonance portion RR1 are connected in parallel on the input side of the power conversion portion 73 to form a power receiving side resonance circuit. For example, the unit-side power receiving section 72 can use a coil. A capacitor can be used for the power receiving side resonance unit RR1. The power converter 73 can include a known rectifier circuit, booster circuit, and inverter circuit. AC power supplied from the power transmission circuit PT0 is rectified by, for example, a rectifier circuit such as a diode bridge. The DC power rectified by the rectifier circuit is boosted to a predetermined voltage by the booster circuit. The boosted DC power is converted into AC power of a predetermined voltage Vac by an inverter circuit.

The predetermined voltage Vac can be set to, for example, a commercial power supply voltage (eg, 100 V, 120 V, 200 V, etc.). In this case, the unit 70 can also supply driving power to electric equipment driven by commercial power.

This allows the feeder 20 to communicate with the line control device LC0 and the management device 211 through the slots of the magazine 227 . Note that the feeder 20 may be individually transferred between the transport device 201 and the feeder storage device BS0 without using the magazine 227 . In this case, the feeder storage device BS0 may not include the connecting portion 245 and may include a slot for directly connecting the feeder 20 without the magazine 227 intervening. Further, the holding portion 551 (see FIG. 3) of the movable portion 51 replaces the feeder 20 with respect to the magazine 227 arranged in the feeder storage device BS0. The holding unit 551 takes out or inserts the feeder 20 from the opening 227A of the magazine 227 to replace the feeder 20 .

The feeder 20 is an example of a workpiece related to the board-to-board working machine of the present disclosure. The work conveyed by the conveying device 201 is not limited to the feeder 20, and may be, for example, a suction nozzle used in the mounting head 30, a squeegee for applying solder used in the printer 203, or the like. Therefore, as the work of the present disclosure, various members used in the board-oriented working machine, for example, replacement elements detachably mounted on the board-oriented working machine can be employed.

The feeder storage device BS0 of this embodiment is capable of supplying power to the transport device 201. FIG. As shown in FIG. 13 , the power supply system 202 of the second embodiment includes a carrier device 201 and a power supply device 250 . The power supply device 250 includes a power transmission section 247 and a supply control section 249 . For example, a power receiving unit 235 is provided at a position on the feeder storage device BS0 side in the Y direction of the mounting unit 223 . A power transmission section 247 of the power supply device 250 is provided on the first rail 41 of the feeder storage device BS0. The power receiving unit 235 can receive power from the power transmitting unit 247 by electromagnetic coupling type contactless power supply, for example. The power transmission unit 247 switches between starting and stopping power supply to the power receiving unit 235 under the control of the supply control unit 249 of the power supply device 250 .

Note that the configurations of the power receiving unit 235, the power transmitting unit 247, and the supply control unit 249 are not particularly limited. For example, the power receiving unit 235, the power transmitting unit 247, and the supply control unit 249 may have the same configuration as the power receiving unit 52, the power transmitting unit 45, and the supply control unit 61 of the first embodiment. The power receiving unit 235 of the conveying device 201 may be inserted into the U-shaped first rail 41 (see FIG. 3) as in the first embodiment (see FIG. 9). The transport device 201 may include a movable power receiving unit 235 . The conveying device 201 moves to the exchange position and moves the mounting portion 223 to the upper portion of the first rail 41, and then inserts the power receiving portion 235 from the mounting portion 223 into the first rail 41. For example, as shown in FIG. Power may be received from the power transmission section 45 by rotating the inserted power reception section 235 as shown.

Alternatively, the feeder storage device BS0 may include the power transmission section 247 for the conveying device 201 separately from the power transmission section 45 for the travel device 50 . For example, the power transmission section 247 may be provided on the top of the first rail 41, on a pair of side walls of the first rail 41 (side walls on the transport device 201 side), or on the bottom of the first rail 41, or the like. Further, the supply control unit 249 may be the same device as the supply control unit 61 of the above embodiment, and may be provided in the line control device LC0. Alternatively, the supply control unit 249 may be a device different from the supply control unit 61 and may be provided in the feeder storage device BS0, the management device 211, the component mounting machine 10, and the like.

The control unit 231 of the conveying device 201 receives power through the power receiving unit 235 from the feeder storage device BS0 that is arranged on the conveying path 217 that is moved by the moving unit 225 to convey the feeder 20 and that transfers the feeder 20 . The control unit 231 charges the battery 221 with power received from the feeder storage device BS0. More specifically, the power board 237 of the transfer device 201 includes, for example, an AC/DC circuit, a rectifier circuit, a transformer circuit, etc., and is connected to the power receiving section 235 . When the conveying device 201 reaches the exchange position, the control section 231 controls the roller driving section 233 to transfer the magazine 227 between the feeder storage device BS0 and the mounting section 223. FIG. The control unit 231 receives power from the feeder storage device BS0 to the power receiving unit 235 while the magazine 227 is being transferred. Under the control of the control unit 231 , the power supply board 237 converts the alternating current received by the power receiving unit 235 into a direct current (charging voltage of the battery 221 ) and supplies the direct current to the battery 221 . As a result, the battery 221 of the transport device 201 can be charged with power received from the feeder storage device BS0 by non-contact power supply during the magazine 227 replacement work. In addition, since the transport device 201 is stopped while the magazine 227 is being delivered, power can be stably supplied to the transport device 201 from the feeder storage device BS0.

Feeder storage device BS0 is an example of an external device of the present disclosure. Note that the external device is not limited to the feeder storage device BS0. For example, various devices can be employed on the transport path 217 along which the transport device 201 shown in FIG. 10 moves. The external device may be the printing machine 203, the print inspection machine 205, the component mounting machine 10, the reflow furnace 207, the board appearance inspection machine 209, or the like. For example, the transport device 201 may receive power from the printer 203 when transporting replenishing solder or a squeegee as a work to the printer 203 . Further, the conveying device 201 may receive electric power from the component mounting machine 10 when conveying a suction nozzle as a work to the component mounting machine 10 .

Further, the conveying device 201 may receive power from an external device such as the printing machine 203 other than the board-working machine. As shown in FIG. 10 , the transport device 201 moves, for example, between a storage room 251 storing the feeders 20 and the magazines 227 and the substrate production line 1 . For example, a feeder management device 253 and a feeder exchange device 255 are arranged in the storage room 251 . The feeder management device 253 is a device that manages the feeders 20, and performs reading of barcodes that identify the feeders 20, and the like. The feeder exchange device 255 is a device that exchanges the magazine 227 with the transport device 201 and exchanges and replenishes the feeder 20 with respect to the magazine 227 . A feeder management device 253 and a feeder exchange device 255 are connected to the network 213 and can communicate with the management device 211 . The feeder exchange device 255 exchanges the magazine 227 with the transport device 201 and replenishes the feeder 20 under the control of the management device 211, for example. The transport device 201 may receive power from the feeder exchange device 255 when transferring the magazine 227 to and from the feeder exchange device 255 .

The production system 200 is also provided with a feeder stock device 257 for stocking magazines 227 and feeders 20 corresponding to each substrate production line 1, for example. The feeder stock device 257 is configured, for example, so that a plurality of magazines 227 can be placed thereon, and is connected to the network 213 by wireless communication. The feeder stock device 257 is provided with a magazine 227 loaded with feeders 20 that are no longer used in the circuit board production line 1 and a magazine 227 loaded with feeders 20 to be used for subsequent production. The feeder stock device 257 transfers the magazine 227 to and from the transport device 201 under the control of the management device 211, for example. The transport device 201 may receive power from the feeder exchange device 255 when transferring the magazine 227 to and from the feeder stock device 257 . Therefore, the external device of the present application is not limited to the board-handling work machine that performs board-handling work on the board 90, and various devices on the transport path 217 along which the transport device 201 moves can be employed.

Further, as shown in FIG. 13, the conveying device 201 includes a communication section 239. The communication unit 239 is connected to the network 213 by wireless communication such as wireless LAN or Bluetooth (registered trademark). Also, the position acquisition device 240 is a device that acquires the current position of the transport device 201 . The configuration of the position acquisition device 240 is not particularly limited. For example, a sensor such as a LIDAR or a millimeter wave radar is used to generate map data in which the transportation route 217 and the topography around the transportation route 217 are detected in advance. The position acquisition device 240 compares detection information such as real-time LIDAR with map data to check the terrain, compares the movement amount of the moving unit 225 (tires) with the map data, or compares map data with the map data. The current position of the conveying device 201 can be acquired by checking the information combining them. Further, for example, the position acquisition device 240 detects the position of the access point of the wireless LAN in the network 213, the processing result of the captured image of the transport path 217, and the wireless communication with the board-to-board work machine of the board production line 1. The current position of the transport device 201 may be acquired based on the position, movement information of the transport device 201, and the like. Alternatively, the position acquisition device 240 may be configured to include a GPS receiver or the like and acquire the current position by GPS. Also, the transport device 201 does not have to include the position acquisition device 240 . The conveying device 201 reads, for example, a magnetic tape, a colored tape, a two-dimensional code, or the like pre-attached to the floor 215 on which the substrate production line 1 is arranged, with a reading device, or detects by imaging with a camera, and conveys the tape. The route 217, stop position (start or goal), etc. may be determined. Also, the above methods may be combined.

The control unit 231 acquires map information of the floor on which the substrate production line 1 is installed from the management device 211 through the communication unit 239, for example. The control unit 231 controls self-propulsion of the own device based on the current position of the transport device 201 acquired from the position acquisition device 240 and the map information. For example, the control unit 231 acquires information on the destination and intermediate points from the management device 211, and sets the transport route 217 based on the acquired information on the destination and the map information. For example, the control unit 231 travels along the set transport route 217 while periodically notifying the management device 211 of the current position of its own device. The management device 211 controls the feeder exchange device 255, the feeder stock device 257, etc. based on the position information acquired from the transport device 201. FIG. For example, when the conveying device 201 reaches the position of the feeder changing device 255 , the management device 211 causes the feeder changing device 255 to start supplying power to the conveying device 201 . Therefore, the management device 211 is an example of the supply control section of the present disclosure. Note that the feeder exchange device 255 and the like do not have to change the power supply under the control of the management device 211 . For example, the feeder exchange device 255 may have a sensor therein and start supplying power when the sensor detects that the conveying device 201 has approached the exchange position. In this case, a supply controller may be provided in the feeder exchange device 255 or the like.

For example, when the controller 231 reaches the front of the feeder storage device BS0 of an arbitrary substrate production line 1, the controller 231 notifies the line controller LC0 of that substrate production line 1 that it has arrived. Upon receiving the notification from the control unit 231, the line control device LC0 acquires the position of the traveling device 50. FIG. For example, when the traveling device 50 moves in front of the component mounting machine 10 and starts working on the component mounting machine 10, the line control device LC0 notifies the conveying device 201 of an instruction to start the replacement work of the magazine 227. When the control unit 231 acquires an instruction to start the replacement work from the line control device LC0, the control unit 231 controls the moving unit 225 to move to the replacement position shown in FIG. 11, and notifies the line control device LC0 that the replacement position has been reached. . Upon receiving the notification from the control unit 231 , the supply control unit 249 of the line control device LC<b>0 starts power supply by the power transmission unit 247 . The transport device 201 charges the battery 221 while exchanging the magazine 227 . Further, when a predetermined condition is established, the control section 231 controls the moving section 225 to move from the replacement position. The supply control unit 249 stops the power supply from the power transmission unit 247 when the control unit 231 moves from the replacement position. The predetermined conditions here are, for example, the condition that the exchange of the magazine 227 is completed, the condition that the battery 221 can be charged to the desired amount of charging power, the condition that the battery 221 can be charged for the desired charging time, and the line control device LC0. It is a condition for obtaining an instruction to move from.

Therefore, the control unit 231 controls the moving unit 225 in accordance with the transfer of the feeder 20 between the traveling device 50 and the component mounting machine 10, and the magazine between the feeder storage device BS0 and the placement unit 223. 227 is moved to the replacement position where the transfer of the 227 can be executed. As a result, the transport device 201 can charge the battery 221 while exchanging the magazine 227 without affecting the exchange operation of the feeder 20 by the traveling device 50 .

Note that the device that notifies the information of the traveling device 50 is not limited to the line control device LC0, and may be another device such as the management device 211 or the like. In addition, the line control device LC0 retracts the travel device 50 from in front of the feeder storage device BS0 to in front of the component mounting machine 10 in accordance with the arrival of the transport device 201 even if the replacement work of the feeder 20 does not occur. Also good. Further, the travel device 50 may detect the existence of the transport device 201 by a human sensor 57 (see FIG. 3) and determine the timing of returning to the feeder storage device BS0.

Also, the control unit 231 executes control for adjusting the charging time based on the charging power and the power consumption. More specifically, for example, the conveying device 201 travels along a first conveying route 217A and a second conveying route 217B shown in FIG. 10, for example. The first transport path 217A is a path that moves from the position of the feeder exchange device 255 in the storage room 251 to the position of the feeder stock device 257 corresponding to the substrate production line 1 at the top of FIG. The second transport path 217B is a path that moves from the feeder stock device 257 to the feeder storage device BS0 of the substrate production line 1 at the top. For example, the transport device 201 starts from the storage room 251 and returns to the storage room 251 in the order of the first transport path 217A, the second transport path 217B, the second transport path 217B, and the first transport path 217A.

Here, for example, when the magazine 227 is transferred between the feeder exchange device 255, the feeder stock device 257, and the feeder storage device BS0 when moving along the first and second transport paths 217A and 217B, Charge the battery 221 . The amount of power of the battery 221 after being charged in each external device is defined as charging power. Also, the amount of power consumed by the battery 221 when moving from the feeder exchange device 255 or the like to the position of the destination external device after executing delivery of the magazine 227 is defined as power consumption. In this case, the control unit 231 adjusts the time for receiving power from the external device so that the power consumption becomes smaller than the charging power.

For example, the control unit 231 starts moving when the charging power equal to or greater than the power consumption required to reach the next destination can be charged. For example, when moving from the feeder exchange device 255 to the feeder stock device 257 on the first conveying path 217A, the control unit 231 determines that the battery 221 can be charged with charging power that is greater than or equal to the power consumed by the movement of the first conveying path 217A. , start moving from the feeder changer 255 .

In addition, by making it possible to charge the battery 221 in each external device on the transport path 217 in this way, it is not necessary to provide a charging station only for receiving power from the battery 221 in the substrate production line 1 or the storage room 251. .

In addition, for example, the control unit 231 uses movable devices such as the feeder stock device 257 and the feeder exchange device 255, as compared with the feeder storage device BS0 and the component mounting machine 10 whose charging time is limited by the movement of the traveling device 50. You may give priority to the charging time in the external device which is not equipped. For example, the control unit 231 causes the charged power after being charged in the feeder stock device 257 to return to the feeder stock device 257 from the feeder stock device 257 via the feeder storage device BS0 by reciprocating the second conveying path 217B. The charging time may be adjusted so that the power consumption is greater than or equal to the required power consumption. That is, the destination external device of the present disclosure is not limited to an external device to which the magazine 227 is transferred next to the arbitrary external device when the magazine 227 is delivered by the arbitrary external device. A variety of external devices encountered on transport path 217 after starting from the external device can be employed. As a result, even if the charging time in the feeder storage device BS0 is shortened due to the movement of the traveling device 50, it is possible to return to the feeder stock device 257 by reciprocating the second transport path 217B.

Further, the power supply device 250 of the second embodiment, when transferring the magazine 227 between the power transmission unit 247 that supplies electric power to the transport device 201 and the transport device 201, the power supply device 250 is supplied from the power transmission unit 247 to the transport device. and a supply control unit 249 for supplying power to 201 . As a result, it is possible to charge the transport device 201 while the magazine 227 is being delivered to the transport device 201 moving on the transport path 217 . A stable supply of power can be executed between the external device related to the board production line 1 and the transport device 201 .

Note that the supply control unit 249 is not limited to the configuration provided in the line control device LC0. For example, the feeder storage device BS0 or the printing machine 203 may include the supply control unit 249 to control the power transmission from the power transmission unit 247 to the transport device 201 that has come to work on itself.

Incidentally, the component mounting machine 10, the printer 203, the print inspection machine 205, the reflow furnace 207, and the board appearance inspection machine 209 are examples of the board-to-board work machine and the external device of the present disclosure.
