In FIG. 3, CAD data of the layout design of the printed circuit board and component mounting data of electronic components to be mounted are set, and the unified CAM data is CAM.
The manual insertion specific data output from the data management system (S1) and created by the manual insertion data conversion processing device and C
Confirm by comparing with AM data (S2). It is confirmed whether or not there is an unregistered part for unique data for manual insertion in the CAM data (S3).
Each is registered and created in the unique data for manual insertion (S4).

On the other hand, if there are no unregistered parts after confirmation in step S3, or after unregistered and created in the manual insertion specific data in step S4, data in which the manual insertion specific data is added to the CAM data is generated. (S5) (The content is shown in FIG. 7) Using the machine classification as a keyword, the data of only the manual insertion part is automatically generated from the CAM data, and the manual insertion part is extracted (S6).

Next, it is determined whether or not the parts other than the manually inserted parts are taken in (S7), and if the data other than the manually inserted parts is to be extracted into the data, the selected part becomes the manually inserted data when manually selected. It is added (S8).
In addition, the data generated in the hand insertion part data is rearranged in order from the lowest mounting height so that the mounting position is not blocked by a hand, a finger, a component with a high mounting height, etc. during manual insertion work. (S9) (contents are shown in FIG. 8).

Next, by minimizing the box for storing the parts,
In order to reduce the preparation time of the parts, the data is divided into blocks according to the part names (S10) (contents are shown in FIG. 9). Further, if similar parts or the like are continuously taken out at the time of taking out parts during manual insertion work, part names may differ due to mixing of parts. Therefore, the similar parts are rearranged so as not to be continuous (S11) (contents are: (Represented in FIG. 11).
Further, the parts are rearranged in order from the smallest X coordinate value and the largest Y coordinate value so that the same component can be inserted while moving from the upper left to the lower right (S12) (contents are shown in FIG. 11). Next, data is added to the part number of the box in which the part is placed by each block of the part name (S13) (the contents are shown in FIG.
2). Further, after outputting a list instructing the order of setting the parts to the printer (S14) (the contents are shown in FIG.
3), and outputs the data to the hand insertion part insertion machine.

The PC 3 considers the number of parts to be inserted, the number of kinds of parts to be inserted, the operating state of each line, the personnel composition of workers, the number of production lots, etc. in order to separate the manual insertion machine line from the divided manual insertion machine line. By performing the predetermined calculation, the assembling time required for the manual insertion line and the assembling time required for the divided manual insertion line are obtained, and the optimum (line capable of more efficient assembling) is determined. Thereby, the manual insertion data or the divided manual insertion data is sent to the line to be used from the PC 3 automatically or according to the operator's instruction. In addition, when the operator operates the PC 3,
You can also force line selection.

FIG. 4 shows the operation of the divided manual insertion data executed by the manual insertion data conversion processing device from the manual insertion data. A data conversion method by the apparatus of this embodiment will be described based on the flowchart of FIG.

First, data for manual insertion is prepared and set (S17), and when the data to be used in the line is selected and executed, the standard values of the number of parts used, the number of machines used, the type of machine, and the ratio of divided data are set. Then, the optimum division number and the optimum tact time are processed and displayed (S18).

If it is determined whether the calculated division number and takt time are sufficient (S19), if the number of personnel, the number of machines, the type of machine, and the division data ratio constituting the line are standard values, the data is divided as it is. In the non-standard case, an arbitrary division number is input (S20), and an arbitrary division data ratio is input (S21). Then, after inputting the number of machines to be used, the data is divided (S22). The divided data is shown in FIGS. 14, 15, 16, and 17. In addition, FIG.
(A), (b), and (c) show an optimal split display screen, split condition setting screen, and split ratio input screen, respectively.

After dividing the data, the optimum tact time calculated in consideration of the number of inserted parts, the insertion time, the insertion load man-hour, etc. is calculated (S23). Then, the time switch for conveyor control is controlled (S24), and the optimum tact time is sent to the conveyor line control device that operates the line to set the tact time (S25). FIG. 19 shows a block diagram for transmitting the tact time to the conveyor line control device. In FIG. 19, 100 is a CPU as a manual insertion conversion processing device for controlling this system, 200 is a time control switch, and 300 is a conveyor control device.

After the takt time is set, the manual insertion machine that uses the list instructing the order of setting the next parts is output to the printer for each manual insertion machine (S26) (the contents are shown in FIG. 13), and then the manual insertion parts insertion machine is used. The data to (S2
7).
