Next, with reference to FIGS. 12 and 13, the configuration of the control system of the autoload unit 40, which is an expansion unit, and the configuration of the part of the control system of the component supply unit 5 (component supply device) connected to the expansion unit. Will be explained. The third connector 41 of the autoload unit 40 and the second connector 30 of the component supply unit 5 are each provided with a plurality of terminals electrically connected to each other in a predetermined arrangement. A second power line 80 arranged in the component supply unit 5 is connected to the power terminal 30a of the second connector 30.

The second power line 80 is connected to the first power line 77 via a switch unit 79 controlled by the feeder control unit 29. When the feeder control unit 29 turns on the switch unit 79, power is supplied from the first power line 77 to the second power line 80, and when the switch unit 79 is turned off, the power from the first power line 77 to the second power line 80 is supplied. The supply is cut off. Further, the switch unit 79 has a function of detecting the current supplied from the first power line 77 to the second power line 80, and when the overcurrent is detected, the power supply to the second power line 80 is cut off. The detection terminal 30b of the second connector 30 is connected to the feeder control unit 29 via the expansion unit detection line 81.

In FIGS. 12 and 13, the other end of the third power line 90 having one end connected to the power supply circuit 91 arranged in the auto load unit 40 at the power terminal 41a of the third connector 41 of the auto load unit 40. Is connected. The power supply circuit 91 supplies electric power to each part of the autoload unit 40. A third power line 90 is connected to the detection terminal 41b of the third connector 41 via a resistor 92 having a high resistance value arranged in the autoload unit 40. That is, by measuring the voltage of the detection terminal 41b of the third connector 41, the state of the power supplied to the third power line 90 can be detected.

Here, with reference to FIGS. 12 and 13, a method of detecting the presence / absence of the autoload unit 40 (expansion unit) by the feeder control unit 29 (first control unit) will be described. When the feeder control unit 29 turns on the switch unit 79 while the autoload unit 40 is mounted on the component supply unit 5 mounted on the component supply unit C, the power terminal of the second connector 30 of the component supply unit 5 is turned on. Power is supplied to the autoload unit 40 from 30a. Then, the voltage of the third power line 90 is output from the detection terminal 41b of the third connector 41. In this case, the detection terminal 30b of the second connector 30 has the same voltage as the third power line 90, that is, the same (almost the same) voltage as the first power line 77.

When the feeder control unit 29 turns off the switch unit 79 while the auto load unit 40 is mounted on the component supply unit 5 mounted on the component supply unit C, the power supply to the auto load unit 40 is cut off. In this case, the detection terminal 30b of the second connector 30 is in the open state. Further, even if the feeder control unit 29 turns on the switch unit 79 while the auto load unit 40 is not mounted on the component supply unit 5 mounted on the component supply unit C, the detection terminal 30b of the second connector 30 Remains open. When the expansion unit detection line 81 is pulled down, the voltage of the expansion unit detection line 81 becomes zero when the detection terminal 30b is in the open state.

In FIGS. 12 and 13, the feeder control unit 29 measures the voltage of the detection terminal 30b of the second connector 30 via the expansion unit detection line 81. If the voltage of the detection terminal 30b is the same (almost the same) as the first power line 77 when the feeder control unit 29 turns on the switch unit 79, the feeder control unit 29 is equipped with the autoload unit 40 (expansion unit). Judge that it has been done. On the other hand, if the detection terminal 30b is in the open state when the feeder control unit 29 turns on the switch unit 79, the feeder control unit 29 determines that the autoload unit 40 is not mounted.

In this way, the second connector 30 is connected to the expansion unit detection line 81 for detecting the presence / absence of the expansion unit (autoload unit 40). The feeder control unit 29 detects the presence or absence of the expansion unit based on the voltage of the expansion unit detection line 81 when the switch unit 79 is turned on and off. Further, when the switch unit 79 is turned on, the switch unit 79 detects an overcurrent in the electric power supplied to the expansion unit, and then cuts off the electric power to the expansion unit. That is, the switch unit 79 is a safety circuit that monitors the power supplied to the expansion unit.

In FIGS. 12 and 13, the communication terminal 30c of the second connector 30 of the component supply unit 5 has a second communication line having one end connected to the second communication unit 85 arranged in the component supply unit 5. The other end of 86 is connected. The second communication unit 85 converts the parallel signal transmitted from the feeder control unit 29 into a serial signal and transmits it to the autoload unit 40. Further, the second communication unit 85 converts the serial signal transmitted from the autoload unit 40 via the second communication line 86 into a parallel signal and transmits it to the feeder control unit 29.

The communication terminal 41c of the third connector 41 of the autoload unit 40 has the other end of the third communication line 93 having one end connected to the extended input / output interface (extended IO) 94 arranged in the autoload unit 40. Is connected. An identification information storage unit 95 and a sensor 50 for detecting the rotation of the expansion sprocket 45 are connected to the expansion IO94. The identification information storage unit 95 is a storage device, and stores information including a unique number for specifying the autoload unit 40, information for specifying the type of the expansion unit, and the like.

In FIGS. 12 and 13, the extended IO 94 converts the information stored in the identification information storage unit 95 and the detection result of the sensor 50 into a serial signal and transmits the information to the feeder control unit 29 via the communication terminal 41c. The extended IO 94 converts the parallel signal transmitted from the feeder control unit 29 and transmits it to the identification information storage unit 95 and the sensor 50. The expansion unit identification unit 76 included in the feeder control unit 29 (first control unit) acquires information for specifying the type of the expansion unit from the identification information storage unit 95 of the autoload unit 40, and connects to the second connector 30. Recognize the type of expansion unit connected.

The operation program storage unit 75 stores a plurality of operation programs corresponding to the types of expansion units connected to the second connector 30. The expansion unit identification unit 76 acquires an operation program corresponding to the recognized type of expansion unit from the operation program storage unit 75 and adapts it to the control by the feeder control unit 29 (for example, updating the firmware wafer). In this way, the feeder control unit 29 (first control unit) has an expansion unit identification unit 76 that recognizes the type of expansion unit connected to the second connector 30 and adapts the operation program to the expansion unit. doing.

In FIGS. 12 and 13, the feeder control unit 29 (first control unit) notifies the component mounting device 1 of the recognition result by the expansion unit identification unit 76 as configuration information 63a or feeder information 63b. That is, as a recognition result, the feeder control unit 29 notifies the component mounting device 1 of at least any one of information such as the presence / absence of the expansion unit, the type of the expansion unit mounted, and the state of the operation program. Then, the configuration information acquisition unit 65 acquires at least the presence / absence of the expansion unit as the configuration information. Further, the feeder information acquisition unit 67 acquires the type of the feeder (parts supply unit 5) specified by the presence / absence of the expansion unit.

The recognition of the type of the expansion unit by the expansion unit identification unit 76 is executed immediately after the feeder control unit 29 turns on the switch unit 79 and starts supplying power to the expansion unit connected to the second connector 30. When the expansion unit identification unit 76 cannot recognize the type of the expansion unit or is not a regular expansion unit, the feeder control unit 29 turns off the switch unit 79 to cut off the power supply. That is, when the expansion unit identification unit 76 cannot recognize the type of the expansion unit, the switch unit 79 (safety circuit) cuts off the power to the expansion unit. This makes it possible to prevent the destruction (failure) of the unknown or inappropriate expansion unit connected to the second connector 30.

In FIGS. 12 and 13, the other ends of the plurality of second control lines 87 having one end connected to the feeder control unit 29 are connected to the plurality of control terminals 30d of the second connector 30. One of the plurality of control terminals 41d of the third connector 41 is connected to the other end of the third control line 96 having one end connected to the motor drive unit 97 arranged in the autoload unit 40. ..

Hereinafter, in the configuration of the wireless communication unit 100, the same parts as those of the autoload unit 40 are designated by the same reference numerals, and detailed description thereof will be omitted. In addition to the identification information storage unit 95, a communication module 101 is connected to the expansion IO 94 included in the wireless communication unit 100. The communication module 101 is a communication module for wireless communication or a wireless module that communicates with a wireless tag.

The parts supply unit 5 to which the wireless communication unit 100 is mounted can wirelessly transmit the information of the parts supply unit 5 to the outside by the communication module 101. A control unit 102 is connected to the plurality of third control lines 96. A status display lamp 103 is connected to the control unit 102. When the wireless communication unit 100 is attached to the component supply unit 5, the control unit 102 is connected to the feeder control unit 29. The control unit 102 blinks the status display lamp 103 based on the command transmitted from the feeder control unit 29.

Hereinafter, in the configuration of the wireless communication unit 110 with a built-in battery, the same reference numerals are given to the same parts as those of the wireless communication unit 100, and detailed description thereof will be omitted. The battery-built-in wireless communication unit 110 includes a secondary battery 111 and a charge control unit 112 that is connected to the control unit 102 to control charging of the secondary battery. The charge control unit 112 controls charging / discharging to the secondary battery 111.

While power is being supplied from the component supply unit 5, power is supplied from the power supply circuit 91 to each part of the wireless communication unit 110 with a built-in battery, and the secondary battery 111 is charged. When the power supply from the component supply unit 5 is cut off, power is supplied from the secondary battery 111 to each part of the battery-built-in wireless communication unit 110. As a result, even when the component supply unit 5 is not connected to an external power source, the information of the component supply unit 5 can be transmitted by transmitting radio waves from the communication module 101 to which power is supplied from the secondary battery 111. can.

Next, according to the flow of FIG. 15, the component supply unit 5 is mounted on the component supply unit C (component supply unit mounting unit 6a), and when power is supplied from the power supply unit 12 to the component supply unit 5, the operation is first executed. The expansion unit identification process will be described. When power is supplied to the component supply unit 5, the feeder control unit 29 turns on the switch unit 79 (ST1). As a result, electric power can be supplied from the power terminal 30a of the second connector 30.

Next, the feeder control unit 29 measures the voltage of the detection terminal 30b of the second connector 30 to detect whether or not the expansion unit is mounted on the second connector 30 (ST2: expansion unit detection processing step). .. That is, the feeder control unit 29 determines that the expansion unit is mounted when the voltage of the detection terminal 30b is the same as that of the first power line 77, and the expansion unit is not mounted when the detection terminal 30b is in the open state. Judge. When the expansion unit is mounted (“Yes” in ST3), the expansion unit identification unit 76 of the feeder control unit 29 reads the identification information that identifies the type of the expansion unit from the identification information storage unit 95 of the expansion unit (ST4). : Identification information acquisition process).

In FIG. 15, when the read identification information is information indicating a legitimate expansion unit (“conformity” in ST5), the expansion unit identification unit 76 enables the conforming operation program stored in the operation program storage unit 75. (ST6: Operation program activation process). For example, when the operation program corresponding to the expansion unit indicated by the read identification information is stored in the operation program storage unit 75, the expansion unit identification unit 76 determines that the expansion unit is a regular expansion unit.

As a result, the feeder control unit 29 can execute the control corresponding to the mounted expansion unit. That is, the component supply unit 5 is changed to a different type of feeder by mounting an expansion unit for expanding the function of the component supply unit 5. For example, when the autoload unit 40 is mounted, the component supply unit 5 becomes an autoload feeder AF. If the expansion unit is not attached, the component supply unit 5 becomes a normal feeder.

Next, the feeder control unit 29 notifies the mounting control unit 13 of the component mounting device 1 of the result of the expansion unit identification process (configuration information 63a, feeder information 63b) (ST7: result notification process). The notification result is stored in the mounting storage unit 63 of the component mounting device 1. For example, the result of the expansion unit identification process is transmitted as information (configuration information 63a) that allows the component mounting device 1 to recognize the configuration of the component supply unit 5, such as the presence / absence of the expansion unit and the identification information of the mounted expansion unit. Alternatively, the result of the expansion unit identification process is transmitted as information (feeder information 63b) that identifies the type of the component supply unit 5 such as the autoload feeder AF and the normal feeder.

In FIG. 15, if the read identification information is not information indicating a legitimate expansion unit, or if the identification information cannot be read (“nonconformity / read failure” in ST5), the feeder control unit 29 turns off the switch unit 79. The power supply to the expansion unit is cut off (ST8). Next, the feeder control unit 29 notifies at least one of the lamp 71 and the display unit 73 of a warning / error (ST9). Next, the result notification step (ST7) is executed, and the feeder control unit 29 notifies the mounting control unit 13 that the expansion unit mounted on the component supply unit 5 is not normal or that the recognition of the expansion unit has failed.

When the expansion unit is not installed (“none” in ST3), the feeder control unit 29 turns off the switch unit 79 to cut off the power supply to the second power terminal 30a (ST10). Next, the result notification step (ST7) is executed, and the feeder control unit 29 notifies the mounting control unit 13 that the expansion unit is not mounted on the component supply unit 5.

As described above, the information (configuration information 63a, feeder information 63b) notified in the result notification step (ST7) is acquired by the mounting control unit 13 (configuration information acquisition unit 65, feeder information acquisition unit 67) and is acquired by the mounting storage unit. It is stored in 63. That is, in the component mounting method in which the component is taken out from the component supply unit 5 mounted on the component supply unit C and mounted on the board B in the component mounting device 1, the configuration information of the component supply unit 5 mounted on the component supply unit C is described. A step of acquiring 63a (configuration information acquisition step) is included.

Alternatively, the component mounting method includes a step of acquiring feeder information 63b including the type of the component supply unit 5 mounted on the component supply unit C (feeder information acquisition step). Then, the component mounting device 1 controls the component supply unit 5 based on the acquired configuration information 63a or feeder information 63b (component supply unit control process), and the mounting head 9 takes out the component from the component supply unit 5 and board B. (Parts mounting process).

Next, according to the flow of FIG. 16, the out-of-stock monitoring process executed in the component mounting device 1 during the component mounting work will be described. During the component mounting work, the out-of-stock determination unit 66 of the mounting control unit 13 causes out-of-stock parts based on the number of remaining parts of the component supply unit 5 mounted on the component supply unit C that supplies the components. Is being monitored (ST11: Out-of-stock monitoring process). That is, in the out-of-stock monitoring step (ST11), it is determined that the parts of the carrier tape T are out of stock.

If no out-of-stock has occurred (No in ST12), the out-of-stock monitoring process (ST11) is continuously executed. When the out-of-stock occurs (Yes in ST12), the unit control unit 64 determines the type of the parts supply unit 5 in which the out-of-stock has occurred (ST13: feeder determination step (type determination of the parts supply unit 5)). Specifically, the unit control unit 64 determines whether or not the component supply unit 5 holding the carrier tape T out of stock from the configuration information 63a or the feeder information 63b has an autoload unit 40 (automatic loading unit). To identify.

In FIG. 16, when the component supply unit 5 out of stock is the autoload feeder AF (Yes in ST14), the unit control unit 64 confirms the mounting state of the subsequent tape T2 (ST15). When the succeeding tape T2 is already set (Yes in ST16), the unit control unit 64 transmits a carrier tape replacement command to the component supply unit 5 (ST17).

That is, if the unit control unit 64 identifies that the out-of-stock component supply unit 5 has the autoload unit 40 (automatic loading unit), the unit control unit 64 ejects the out-of-stock carrier tape T (leading tape T1). A command to automatically load a new carrier tape T (subsequent tape T2) is output to the component supply unit 5. After that, the unit control unit 64 returns to the out-of-stock monitoring step (ST11). The mounting control unit 13 suspends the removal of parts from the autoload feeder AF (or parts from another parts supply unit 5) while the carrier tape is being replaced in the autoload feeder AF. Is fetched first).

In FIG. 16, when the succeeding tape T2 is not set (No in ST16), the unit control unit 64 transmits a carrier tape discharge command instructing the component supply unit 5 to discharge the preceding tape T1, and the notification unit 61 or A component replenishment notification command for notifying the touch panel 62 of component replenishment is transmitted (ST18). After that, the unit control unit 64 returns to the out-of-stock monitoring step (ST11).

When the parts supply unit 5 out of stock is a normal feeder (No in ST14), a parts replenishment notification command for notifying the notification unit 61 or the touch panel 62 of parts replenishment is transmitted (ST19). That is, if the unit control unit 64 determines that the out-of-stock parts supply unit 5 does not have the autoload unit 40 (automatic loading unit), the unit control unit 64 outputs a command (parts replenishment notification command) for notifying the out-of-stock parts. .. After that, the unit control unit 64 returns to the out-of-stock monitoring step (ST11).

As described above, the unit control unit 64 has identified that the component supply unit 5 holding the carrier tape T out of stock due to the configuration information 63a or the feeder information 63b has an automatic loading unit (autoload unit 40). If so (Yes in ST14), a command to discharge the out-of-stock carrier tape T (leading tape T1) and automatically load a new carrier tape T (successor tape T2) is output to the component supply unit 5 (Yes). In ST17), if it is identified as having no automatic loading unit (No in ST14), a command for notifying out of stock is output (ST19). Thereby, the component replenishment process for appropriately replenishing the carrier tape T can be executed according to the mounted expansion unit.

Next, according to the flow of FIG. 17, the carrier tape transfer process executed by the normal feeder, which is the component supply unit 5 to which the expansion unit is not mounted, according to the command from the unit control unit 64 will be described. During the component mounting work, the feeder control unit 29 is waiting for a command from the unit control unit 64 (ST21: command waiting process). When the command is not received (No in ST22), the command waiting process (ST21) is continuously executed. Upon receiving the command (Yes in ST22), the feeder control unit 29 controls each part of the component supply unit 5 according to the received command (ST23 to ST26).

Specifically, upon receiving the "1 pitch feed command", the feeder control unit 29 controls the carrier tape transfer motor 33 to transfer the carrier tape T by 1 pitch (ST24: 1 pitch transfer process). Upon receiving the "notification command", the feeder control unit 29 controls the lamp 71 and the display unit 73 to notify the commanded content (ST25: notification processing step). Further, the feeder control unit 29 causes various processes to be executed in response to other commands (ST26). When the received command is executed, the feeder control unit 29 returns to the command waiting process (ST21).

Next, along the flow of FIG. 18, the carrier tape transfer process executed by the autoload feeder AF, which is the component supply unit 5 to which the autoload unit 40 is mounted, according to the command from the unit control unit 64 will be described. The same steps as the carrier tape transfer process of the normal feeder are designated by the same reference numerals, and detailed description thereof will be omitted. If no command is received during the component mounting work (No in ST22), the command waiting process (ST21) is continuously executed. Upon receiving the command (Yes in ST22), the feeder control unit 29 controls each part of the component supply unit 5 according to the received command (ST23 to ST26, ST31).

Specifically, when the "1 pitch feed command" is received, the 1 pitch transfer process (ST24) is executed. Upon receiving the "notification command", the notification processing step (ST25) is executed. Upon receiving the "tape replacement command", the feeder control unit 29 controls the carrier tape transfer motor 33 and the motor drive unit 97 of the autoload unit 40 to discharge the preceding tape T1 and replace it with the succeeding tape T2. (Parts replenishment process) is executed (ST31: tape replacement process). Further, the feeder control unit 29 causes various processes to be executed in response to other commands (ST26). When the received command is executed, the feeder control unit 29 returns to the command waiting process (ST21).

As described above, in the component mounting device 1, the component supply unit C to which the component supply unit 5 for supplying the component housed in the carrier tape T is detachably mounted and the component supply unit C mounted to the component supply unit C are supplied. The configuration information acquisition unit 65 for acquiring the configuration information 63a of the unit 5 (or the feeder information acquisition unit 67 for acquiring the feeder information 63b including the type of the component supply unit 5 mounted on the component supply unit C) and the component supply unit.
