Here, an example of individual management will be described with reference to FIG. 5A. FIG. 5A is a diagram illustrating an example of individual management by the mounting line management device (process management device) 5. In individual management, the start time or end time of the carry-in process, work process, and carry-out process is collected from each production device. In the loader device M8, the unloading process is started at time T11, and the unloading process is completed at time T12. Here, the time T11 is the time when the conveyor included in the loader device M8 starts to move, and the time T12 is the actual time when the conveyor ends moving. In the loader device M8, the identification information Q attached to the substrate B is recognized by the recognition unit R at the time Tr1 when the conveyor is moving (time T11 to T12) (the recognition step is carried out).

In the deformed parts mounting device M9, the loading process is carried out at times T21 to T22, the work process (parts mounting work) is carried out at times T22 to T23, and the carrying-out process is carried out at times T23 to T24. In the deformed component mounting device M9, the loading process is started during the loading process (time T11 to T12) of the loader device M8 (time T11 <time T21 <time T12). In the local soldering apparatus M10, the carry-in process is carried out at times T31 to T32, the work step (local soldering work) is carried out at times T32 to T33, and the carry-out step is carried out at times T33 to T34. In the local soldering device M10, the carrying-in process is started during the carrying-out process (time T23 to T24) of the deformed component mounting device M9 (time T23 <time T31 <time T24).

In FIG. 5A, in the unloader device M11, the carry-in process is carried out at times T41 to T42. In the unloader device M11, the recognition step is performed at time Tr2 while the conveyor is moving (time T41 to T42). The production time calculation unit 34 calculates the time when the parts mounting work of the deformed parts C1 and C2 on the substrate B is completed from the collected working time of the deformed part mounting device M9 and the standard working time included in the standard time data 31b ( presume.

Specifically, the production time calculation unit 34 adds the standard working time D11 of the component mounting work of the deformed component C1 included in the standard time data 31b to the time T22 at which the component mounting work is started, and adds the deformed component C1. The end time T25 (T22 + D11) of the component mounting work of the above is calculated. Further, the production time calculation unit 34 adds the standard working time D12 of the component mounting work of the deformed part C2 to the calculated end time T25 of the component mounting work of the deformed part C1 to end the component mounting work of the deformed part C2. The time T26 (T22 + D11 + D12) is calculated.

Next, an example of integrated management will be described with reference to FIG. 5B. FIG. 5B is a diagram illustrating an example of integrated management by the mounting line management device (process management device) 5. In this example, it is assumed that the management method determined on the management method setting screen 40 shown in FIG. 4 is set. That is, the loader device M8 and the unloader device M11 are set as the information collection target production devices. From the loader device M8 and the unloader device M11, the identification information Q attached to the substrate B is collected by the recognition unit R. The production time calculation unit 34 sets the standard from the recognition process of the loader device M8 included in the standard time data 31b to the end of the loading process of the deformed component mounting device M9 at the time Tr3 when the identification information Q is collected from the loader device M8. The work time D21 is added to calculate (estimate) the end time T51 (Tr3 + D21) (start time of the work process) of the carry-in process.

Similarly, the production time calculation unit 34 adds the standard work time D22 of the component mounting work to the end time T51 of the carry-in process to calculate the end time T52 (Tr3 + D21 + D22) (start time of the carry-out process) of the work process. Further, the production time calculation unit 34 calculates the end time T53 (Tr3 + D21 + D22 + D23) of the carry-out process by adding the standard work time D23 of the carry-out process to the end time T52 of the work process.

In FIG. 5B, the production time calculation unit 34 collects the identification information Q in the unloader device M11 after the unloading process of the local soldering device M10 is started from the time Tr4 in which the identification information Q is collected from the unloader device M11. The standard working time D33 up to is subtracted to calculate (estimate) the start time T63 (Tr4-D33) (end time of the work process) of the carry-out process.

Similarly, the production time calculation unit 34 subtracts the standard work time D32 of the local soldering work from the start time T63 of the carry-out process to start the work process start time T62 (Tr4-D33-D32) (end time of the carry-in process). Is calculated. Further, the production time calculation unit 34 calculates the start time T61 (Tr4-D33-D32-D31) of the carry-in process by subtracting the standard work time D31 of the carry-in process from the start time T62 of the work process. In this way, even if the production information is not collected from the deformed component mounting device M9 or the local soldering device M10, the deformed component mounting device M9 or the local soldering device M9 or the local soldering device M9 or the local soldering device M9 or the local soldering device M9 is based on the production information collected from other production devices and the standard working time. The start time and end time of the production process of the attachment device M10 can be calculated. As a result, accurate process control can be executed.

Next, another example of integrated management will be described with reference to FIG. FIG. 6 is a diagram illustrating another example of integrated management by the main mounting line management device (process management device) 5. In this example, only the loader device M8 is set as the information collection target production device. The production times T71 to T73 of the deformed component mounting device M9 are calculated by adding the standard working times D21 to D23 to the time Tr5 when the identification information Q is collected from the loader device M8, as in the example of FIG. 5B. The production time calculation unit 34 starts the process of recognizing the loader device M8 included in the standard time data 31b and the process of carrying in the local soldering device M10 at the time Tr5 when the identification information Q is collected from the loader device M8. The standard working time D41 is added to calculate the start time T81 (Tr5 + D41) of the carry-in process.

Further, the production time calculation unit 34 adds the standard work time D31 of the carry-in process to the start time T81 of the carry-in process to calculate the end time T82 (Tr5 + D41 + D31) (start time of the work process) of the carry-in process. Further, the production time calculation unit 34 calculates the end time T83 (Tr5 + D41 + D31 + D32) (start time of the carry-out process) of the work process by adding the standard work time D32 of the local soldering work to the end time T82 of the carry-in process. Further, the production time calculation unit 34 calculates the end time T84 (Tr5 + D41 + D31 + D32 + D33) of the carry-out process by adding the standard work time D33 of the carry-out process to the end time T83 of the work process.

As described above, the mounting line management device 5 of the present embodiment is set to integrated management that manages the production process as one group, or individual management that manages each process of the production process individually. In the case of integrated management, work information is collected from at least one of a plurality of devices in the production process, and in the case of individual management, work information is collected from each device in the production process. It is a process control device that manages the production process. As a result, accurate process control can be executed in production lines having various configurations. The production time described below is calculated based on the start time and end time of the work process.

Next, a process management method (process management) for managing the production process including the carry-in process of carrying in the work (board B), the work process of working on the work, and the carry-out process of carrying out the work according to the flow of FIG.

(ST1: Management method setting process).

In the case of integrated management (Yes in ST2), the recognition unit R recognizes the identification information Q attached to the work (board B) in at least one of the carry-in process and the carry-out process (ST3: identification information recognition step). Next, the information collecting unit 33 collects the information of the work (board B) recognized from the identification information Q (ST4: work information collecting step). That is, in the case of integrated management, work information is collected in at least one of a plurality of production processes. Next, the production time calculation unit 34 calculates the production time (process start time, process end time) of the work in the production process from the time when the work information is collected and the standard work time (ST5: integrated control production time calculation process). .. That is, in the case of integrated management, the work production time is calculated from the time when the work information is collected (see FIGS. 5B and 6).

In FIG. 7, in the case of individual management (No in ST2), work information is collected in each process of the production process (ST6: work information collection process). Next, the production time calculation unit 34 calculates the production time of the work (board B) from the collected work information in each process and the standard work time (ST7: Individually controlled production time calculation process). By setting the control method according to the production line in this way, it is possible to execute accurate process control in the production lines having various configurations.
