  On the basis of the electric circuit board information and the production amount information from the host computer 152 described above, the master device and the slave device take out from the electric component supply devices 16, 18 by the mounting heads 50, 52 of the electric component transport mounting devices 20, 22. When the electrical components are sequentially mounted on the printed wiring board 32 and mounting of the electrical components in one electrical component mounting machine 10 is completed, the electrical components are sent to the next apparatus on the downstream side in the transport direction. During the work, how many printed wiring boards 32 are currently working, whether it is in the middle of the mounting work, whether it has been completed, whether there are defective electrical components or mounting defects, Status data indicating whether or not the holder is defective is transmitted from each slave device to the master device in association with the device numbers A, B, C, D... Of each slave device. The master device can control the electric circuit board assembly line including the master device and the plurality of slave devices based on the situation data.

  In S10, it is determined whether or not the above-mentioned status data is transmitted from the slave device. If the determination is YES, the transmitted status data is stored in the slave information memory (work progress information memory 170, product status information memory 172, and so on). It is stored in the device status information memory 174). Based on the status data from the slave device, it is determined in S12 whether it is necessary to send a control command from the master device to the slave device. As a case where it is necessary to send a control command from the master device, for example, there is a case where an electrical component mounting error occurs in one slave device, and the printed wiring board 32 during the mounting operation becomes a defective product. is there. In such a case, the determination in S12 is YES, and a control command is transmitted from the master device to each slave device in S13. In this case, the control command is a command for prohibiting the device downstream of the slave device in which the mounting error has occurred from performing the mounting operation on the defective printed wiring board 32, and the mounting error has occurred. This is a command to increase the number of printed wiring boards 32 to be mounted to the apparatus upstream of the slave apparatus by one. Therefore, after the occurrence of the mistake, the printed wiring board 32 in which the installation error has occurred is eliminated without performing the mounting operation. Then, by carrying the mounting work by transporting the printed wiring boards 32 increased by 1 from the number of planned printed wiring boards 32, a predetermined number of printed circuit boards are finally completed. After the execution of S13, other processes related to the electric circuit board assembly are executed in S14. If the determination in S10 is NO, S11 and subsequent steps are skipped, and if the determination in S12 is NO, S13 is skipped and S14 is executed.

  On the other hand, in the slave device, as shown in the flow on the right side of FIG. 5, in S26, it is determined whether there is status data that needs to be transmitted from the slave device to the master device. If the determination is YES, status data is transmitted from the slave device to the master device in S27. Then, in S28, it is determined whether or not a control command is transmitted from the master device. If a control command is issued from the master device and the determination is YES, the control command is executed in the slave device in S29, and the execution of the control command is transmitted to the master device in S30. After execution of S30, other processing is executed in S31. If the determination in S26 is NO, S27 and subsequent steps are skipped. If the determination in S28 is NO, S29 and S30 are skipped and S31 is executed. The master device and the slave device manufacture the printed circuit board while repeating the above steps.

  As a situation where a control command is required, there is a case where one type of electrical component cannot be supplied in one slave device, for example, in addition to the above-described example. If a single slave device is equipped with a plurality of electrical component supply feeders 42 that accommodate the same type of electrical components, the same type of electrical components are accommodated if one feeder 42 cannot supply the components. Control is performed by the control device 100 of the slave device so that the electrical components are supplied from the feeder 42, but the control command from the master device is required for the same kind of electrical components in one slave device. This is a case where there is no feeder 42 for supplying all the electrical components, or all the electrical components are supplied from a plurality of feeders 42 for supplying the same type of electrical components. The fact that one type of electric component cannot be supplied in one slave device is transmitted as status data to the master device. Based on the status data, if there is a device that can supply the same type of electrical component to another slave device, the master device supplies the slave device with the electrical component in place of the slave device that cannot be supplied. Thus, a control command can be transmitted.

  That is, the master device grasps the situation such as whether or not work is being performed in the slave device according to the production plan from the host computer 152, and if a failure occurs, the master device issues a control command for solving it. It is sent to the device and the electric circuit board assembly line is managed collectively. On the other hand, the slave device attaches electrical components to the printed wiring board 32 that has been conveyed in accordance with the command, and transmits the command execution and the work status in the slave device to the master device. The communication device 144 of each electrical component mounting machine 10 can take only information relevant to itself into the control device 100, and can shut out other unrelated information. For example, the host computer 152 is connected to the communication devices 144 of all the electrical component placement machines 10, but only the communication device 144 of the electrical component placement machine 10 that functions as a master device controls information from the host computer 152. The communication device 144 of the remaining electrical component mounting machine 10 that functions as a slave device receives the information only via the master device. All information from each slave device is transmitted to the master device, and the master device can collectively manage the status of each slave device. Therefore, the operator only has to operate the master device, and the operator's work efficiency is improved as compared to operating all of the electric component mounting machines 10, and the entire electric circuit board assembly line can be managed. It becomes easy. In addition, the master device automatically monitors and controls the slave device, and the production efficiency of the electric circuit board assembly line is improved.

  In the above, the case where the electrical component mounting machine 10A is a master device has been described, but this is an example, and any of the electrical component mounting machines 10A, B, C, D... Operates as a master device or a slave device. As shown in the figure, a master program and a slave program are provided, and the electrical component mounting machines 10B, C, D, etc. other than the electrical component mounting machine 10A are mastered according to circumstances such as production planning. It can also function as a device. For example, when the electrical component mounting machine 10A operating as the master device fails, the electrical component mounting machine 10B operating as the slave device is replaced with the failed electrical component mounting machine 10A from the electrical circuit board assembly line. Work can be continued without any problems.
