Next, the operation of the mounting system 10 thus configured will be described. In the mounting system 10, each device performs work based on information such as work instructions and production programs transmitted from the management control unit 91 of the management device 90. In addition, the management control unit 91 creates information on the quality of each work. The management control unit 91 receives information on the print inspection result from the print inspection device 22 for each board S or the like and creates the print inspection result information shown in FIG. 8, or information on the mounting work from the mounting device 40 for each board S or the like. Is received and the mounting work state information shown in FIG. 9 is created, or the mounting inspection result information is received from the mounting inspection device 26 for each board S or the like and the mounting inspection result information shown in FIG. 10 is created. This information is stored in the storage unit 92. The print inspection result information of FIG. 8 includes the board ID of the board S, the mask ID of the screen mask M, the print pattern ID for each print location, and the information related to the print state such as width shift, position shift, and height shift. It is the associated information.

Is the information associated with. The suction state is information on the positional deviation and the angular deviation of the parts obtained by photographing the parts sucked by the nozzle 44 with the parts camera 46 and processing the captured images. The mounting inspection result information in FIG. 10 is information in which the board ID, the component type, the component number, the mounting position, and the mounting state are associated with each other. The mounting state is information regarding the positional deviation and the angular deviation of the parts measured by the mounting inspection device 26.

Subsequently, the operation related to the maintenance of various units in the mounting system 10 will be described. FIG. 11 is a flowchart showing a mask maintenance processing routine. This routine is executed by the management control unit 91 of the management device 90 when the above-mentioned print inspection result information is updated. In this routine, the management control unit 91 first analyzes the print inspection result information (S100), and determines whether or not it is a sign state in which a sign of abnormality due to the screen mask M is observed (S110). Here, if the screen mask M is deformed due to distortion or the like and the pattern holes are widened or the positions are displaced, the solder coating area increases and the solder width shift abnormality occurs, or the solder coating positions are displaced and the solder is displaced. Misalignment may occur. Further, when the solder is clogged in the pattern hole, the solder coating area is reduced and the width of the solder is abnormal, or when the surface of the screen mask M is scraped and the thickness is reduced, the filling height of the solder in the pattern hole is increased. Is low and the solder height is abnormal. Such abnormalities caused by the screen mask M often occur as the screen mask M is used repeatedly. Therefore, the management control unit 91 can analyze the print inspection result information and determine the sign state before the abnormality from the tendency of the change of each numerical value of the width deviation, the position deviation, and the height deviation. When the management control unit 91 determines in S110 that the state is not a sign state, the management control unit 91 ends the mask maintenance processing routine as it is.

Further, when the management control unit 91 determines in S110 that it is in a sign state, it determines that it is the maintenance time of the screen mask M (S120), and the screen mask M in which the same pattern hole is formed from the mask storage unit of the storage 70 is formed. Is transmitted to the automatic guided vehicle 100 (S130) and waits for the automatic guided vehicle 100 to arrive at the printing device 30 (S140). The automatic guided vehicle 100, which has received the instruction of S130, automatically carries out the screen mask M from the mask storage unit and transports the screen mask M to the printing device 30. Then, when the automatic guided vehicle 100 arrives at the printing device 30, the management control unit 91 waits for the screen mask M to be replaceable due to the printing status of the printing device 30 (S150). When the management control unit 91 determines that the substrate S being printed by the printing apparatus 30 can be replaced due to being carried out or the like, the used screen mask M used in the printing apparatus 30 and the new one transported this time are transferred. An instruction for replacement with the screen mask M is transmitted to the printing device 30 and the automatic guided vehicle 100 (S160), and the replacement is waited for completion (S170). For example, in the automatic guided vehicle 100, when a new screen mask M is mounted on the rear mounting portion 103b, first, the front mounting portion 103a is pushed out from the printing device 30 toward the printing device 30. Receive the used screen mask M. Next, the automatic guided vehicle 100 replaces the screen mask M by pushing out a new screen mask M by the extrusion device 104 toward the printing device 30 with the rear mounting portion 103b and carrying it into the printing device 30. do.

When the screen mask M is replaced in this way, the management control unit 91 transmits an instruction to transport the used screen mask M to the mask maintenance device 81 to the automatic guided vehicle 100 (S180), and the automatic guided vehicle 100 masks. Wait for the maintenance device 81 to arrive (S190). When the unmanned transport vehicle 100 arrives at the mask maintenance device 81, the management control unit 91 gives an instruction to the mask maintenance device 81 and the unmanned transport vehicle 100 to pass the used screen mask M to the mask maintenance device 81 for maintenance. It is transmitted (S195) and the mask maintenance processing routine is terminated. As a result, when the sign state of the abnormality caused by the screen mask M is determined, the screen mask M can be automatically replaced and maintained, so that quality abnormalities such as printing defects can be prevented from occurring frequently. be able to. Further, the screen mask M can be automatically replaced and maintained at an appropriate timing according to the working condition of the printing apparatus 30 without the need for replacement work or maintenance by the operator. When the maintenance of the screen mask M is completed, the management control unit 91 sends an instruction to transport the screen mask M to the mask storage unit of the storage 70 to the automatic guided vehicle 100, and the screen mask M is transferred to the mask storage unit. It can be stored. As a result, the replacement of the screen mask M in the printing device 30, maintenance, and subsequent storage can be automatically performed by using the automatic guided vehicle 100 without depending on the operator.

Further, FIG. 12 is a flowchart showing a nozzle feeder maintenance processing routine. This routine is executed by the management control unit 91 when the above-mentioned mounting work status information or mounting inspection result information is updated. In this routine, the management control unit 91 first analyzes the mounting work state information or the mounting inspection result information (S200), and whether or not it is a sign state in which a sign of abnormality caused by the specific feeder 50 is observed (S200). S210), it is determined whether or not it is a sign state in which a sign of abnormality caused by the specific nozzle 44 is observed (S220). The management control unit 91 may analyze both the mounting work state information and the mounting inspection result information in S200. Here, if a feeding defect or the like occurs in the tape feeding mechanism 53 of the feeder 50, the supply position of the parts supplied from the feeder 50 is displaced, so that the positional deviation or the angular deviation of the components supplied from the feeder 50 is displaced. It may tend to occur frequently. Further, when the nozzle 44 is bent or a large amount of dust or dust adheres to the nozzle 44, suction failure is likely to occur, and there is a tendency that the position shift and the angle shift of the parts sucked by the nozzle 44 frequently occur. There is. Therefore, the management control unit 91 analyzes the mounting work state information or the mounting inspection result information, and is specific from the tendency of the change of each numerical value of the position shift and the angle shift and the presence or absence of the correlation with the feeder ID and the nozzle ID. The predictive state of the feeder 50 or a specific nozzle 44 can be determined. When the management control unit 91 determines in S210 and S210 that neither of the precursor states is present, the management control unit 91 ends the nozzle feeder maintenance processing routine.

When the management control unit 91 determines in S210 that it is a sign state of the specific feeder 50, it determines that it is the maintenance time of the specific feeder 50 and sets it in the work unit to be maintained (S230). Further, when the management control unit 91 determines in S220 that it is a sign state of the specific nozzle 44, it determines that it is the maintenance time of the specific nozzle 44 and sets it in the work unit to be maintained (S240). Next, the management control unit 91 sends an instruction to the automatic guided vehicle 100 to carry out the replacement work unit from the feeder storage unit of the storage 70 and transport it to the temporary storage site 24 (S250). If the maintenance target is the feeder 50, the management control unit 91 instructs to carry out and transport the replacement feeder 50 containing the same type of parts, and if the maintenance target is the nozzle 44, the same type of nozzle. Instruct to carry out and carry out the nozzle replacement unit 150 accommodating 44. Subsequently, the management control unit 91 sends an instruction to carry out the used work unit to be maintained to the temporary storage place 24 to the mounting device 40 and the exchange robot 60 (S260), and the automatic guided vehicle 100 is sent to the temporary storage place 24. Wait for arrival (S270). The automatic guided vehicle 100 moves to the front of the temporary storage site 24 after waiting for the completion of the work of transferring the used work unit to the temporary storage site 24 by the communication with the management control unit 91. Then, when the automatic guided vehicle 100 arrives at the temporary storage place 24, the management control unit 91 transmits an instruction to replace the used work unit with the new work unit carried this time to the automatic guided vehicle 100 (S280). Wait for the exchange to be completed (S290).

When the work unit is replaced in this way, the management control unit 91 transmits an instruction to transport the used work unit to the corresponding maintenance device to the automatic guided vehicle 100 (S300), and the automatic guided vehicle 100 sends the instruction to the maintenance device. Wait for arrival (S310). If the maintenance target is the feeder 50, the management control unit 91 instructs the feeder to be conveyed to the feeder maintenance device 84, and if the maintenance target is the nozzle 44 (nozzle replacement unit 150), the management control unit 91 instructs the transfer to the nozzle maintenance device 87. And so on. Then, when the automatic guided vehicle 100 arrives at the maintenance device, an instruction to hand over the used work unit to the maintenance device for maintenance is transmitted to the maintenance device and the automatic guided vehicle 100 (S320), and the nozzle feeder maintenance is performed. End the processing routine. As a result, the feeder 50 and the nozzle 44 can be automatically replaced and maintained at the timing when the sign state of the abnormality caused by the specific feeder 50 or the specific nozzle 44 is determined, so that the quality abnormality such as a mounting defect can be performed. Can be prevented from occurring frequently. When the maintenance of the feeder 50 and the nozzle 44 is completed, the management control unit 91 can send an instruction to transport them to the storage 70 to the automatic guided vehicle 100 and store them in the storage 70. .. As a result, the replacement of the feeder 50 and the nozzle 44, maintenance, and subsequent storage can be automatically performed by using the automatic guided vehicle 100 regardless of the operator.

In the above-described embodiment, the maintenance time of the work unit in use in the work device is determined, but the present invention is not limited to this. The screen mask M that has been used in the printing apparatus 30 and then removed due to a change in the substrate type and stored in the storage 70, and the screen mask M that has been used in the mounting apparatus 40 and then removed due to a change in the substrate type and the like. The maintenance time of the work unit stored in the storage 70, such as the feeder 50 and the nozzle 44 (nozzle replacement unit 150) stored in the storage 70, may be determined. FIG. 13 is a flowchart showing a periodic maintenance processing routine of the modified example. This process is executed by the management control unit 91 of the management device 90 at regular timings.

In this periodic maintenance processing routine, the management control unit 91 first selects a work unit stored in the storage 70 as a processing target (S400). The management control unit 91 selects, for example, a work unit newly stored in the storage 70 as a processing target. Next, the management control unit 91 acquires the number of times of use and the use time of the selected work unit (S410). The number of times of use is defined as the number of times of printing on the substrate S using the screen mask M (number of prints), the number of parts supplied by the feeder 50, the number of times of suction of parts by the nozzle 44, and the like, and is reset by maintenance. Further, the usage time is defined as the time from when the work unit is attached to the work device and the work of the first board S is started until the work unit is removed from the work device. Subsequently, the management control unit 91 determines whether or not the work unit has been used a predetermined number of times or more (S420), and whether or not the work unit has been used for a predetermined time or more (S430). When the management control unit 91 determines that the number of times of use is the predetermined number of times or more or the use time is the predetermined number of times or more, it determines that it is the periodic maintenance time of the selected work unit (S440), and the number of times of use is not the predetermined number of times or more. If it is determined that the usage time is not longer than the predetermined time, the periodic maintenance processing routine is terminated. The management control unit 91, which has determined that it is time for regular maintenance, sends an instruction to the automatic guided vehicle 100 to carry out the work unit from the storage 70 and transport it to the corresponding maintenance device (S450), and the automatic guided vehicle 100 sends the maintenance device. Wait for arrival at (S460). Then, when the automatic guided vehicle 100 arrives at the maintenance device, the management control unit 91 transmits an instruction to hand over the work unit to the maintenance device to perform maintenance to the maintenance device and the automatic guided vehicle 100 (S470), and periodically. End the maintenance process routine. As a result, it is possible to reliably perform maintenance of the work unit at regular timings without the need for transportation and maintenance by the operator. Moreover, it does not affect the operating rate of the working equipment. Therefore, it is possible to improve the work quality without lowering the operating rate. It should be noted that the determination is not limited to the one using both the number of uses and the usage time, and the maintenance time may be determined using either the number of uses or the usage time. Further, when the period of storage in the storage 70 is longer than a predetermined period, it may be determined that the maintenance time is reached.

Further, the determination of the maintenance time based on the number of times of use and the use time may be applied to the work unit being used by the work device. That is, when the management control unit 91 determines the periodic maintenance time of the work unit being worked on by the work device based on either one or both of the number of times of use and the use time, and determines that the periodic maintenance time is determined, the automatic guided vehicle 100 determines. It may be replaced automatically for maintenance.

In the above-described embodiment, the work unit is conveyed by the automatic guided vehicle 100 capable of automatic traveling, but any work unit may be conveyed by an automatic guided vehicle, and may be conveyed by a conveyor device or the like. , May be transported by an automatic flying object such as a drone. Further, the exchange robot 60 is provided on the mounting line 20, and the automatic guided vehicle 100 is supposed to transfer the feeder 50 or the like to the temporary storage place 24. However, the automatic guided vehicle 100 is not limited to this, and the automatic guided vehicle 100 is used as a feeder on each mounting device 40. 50 and the like may be directly transferred.
