The sort processing unit 112 performs a sort process for arranging parts for each process. A process parts table is generated by the process addition processing unit 110 and the sort processing unit 112.

  FIG. 10 shows an example of a process parts table. As shown in the figure, the parts are classified for each process. As shown in the figure, the process parts table shows a hierarchical structure of processes.

  The data transmission unit 114 provides a communication function with the production management system 116. The data transmission unit 114 transmits the process parts table to the production management system 116. The process parts table is used by the production management system 20 for purchase information processing, unit price determination processing, and the like.

  Next, the operation of the process parts table generation server 18 will be described. First, the user operates the client PC 24 and inputs an instruction for taking in a used part / automatic arrangement key file. The capture instruction is received by the transmission / reception unit 100 via the network 22 and transmitted to the data reception unit 102.

  The data receiving unit 102 receives the used component / automatic arrangement key file from the board CAD server 14 in response to the data fetching instruction. Here, the data receiving unit 102 requests the board CAD server 14 to transmit data, and receives data sent from the board CAD server 14. The data receiving unit 102 provides the used part / automatic arrangement key file to the process assignment processing unit 110. In addition, a data reception notification is sent from the data receiving unit 102 to the transmitting / receiving unit 100 and sent from the transmitting / receiving unit 100 to the client PC 24. The notification of data reception is also supplied to the template selection unit 108.

  Upon receiving the data reception notification, the template selection unit 108 performs processing for selecting a template as described below. The template selection unit 108 presents a plurality of templates stored in the template master storage unit 104 to the client PC 24 and prompts selection of a template. In the client PC 24, an instruction to select a template is input by the user. This instruction is sent to the substrate CAD server 14 and accepted by the template selection unit 108. The template selection unit 108 selects a template indicated by the received instruction. The template selection unit 108 reads out the selected template from the template master storage unit 104 and supplies it to the process provision processing unit 110.

  Through the processing up to this point, the process assignment processing unit 110 is provided with a used part / automatic arrangement key file and a template. The process assignment processing unit 110 refers to the template and obtains the process of each part included in the used part / automatic arrangement key file. Here, the process corresponding to the automatic placement key in the file is obtained from the template. And the item number is arranged according to the process. This process is performed by the sort processing unit 112. A process parts table as shown in FIG. 10 is generated by the process addition processing unit 110 and the sort processing unit 112. As shown in the drawing, the process parts table also shows a hierarchical structure corresponding to the parent process of the template. The process parts table generated in this way is output to the production management system 20 by the data transmission unit 114.

  Next, a preferred example of detailed processing related to generation of a process parts table will be described. Here, a workpiece process parts table database and a process parts table database are used. These databases are working databases and are provided on a memory.

  FIG. 11 is a template similar to FIG. However, in FIG. 11, information for level and automatic numbering is added to the template. The level indicates the level of the own process in the hierarchical structure.

  FIG. 12 shows a workpiece process parts table database. As shown in the figure, the workpiece process parts table database has columns of process level and item number. First, as shown in FIG. 12A, information on all processes shown in the template of FIG. 11 is output to the work process parts table database. At this time, the process level is shifted as it is. Further, the process name of the template is converted into an item number based on the automatic numbering information. In the example of FIG. 12, an appropriate number “01” is added to the automatic numbering information. For example, the process name “manual insertion process” is converted into an item number “AAA01” (automatic numbering information “AAA” added with “01”). Then, the converted item number is output to the work process parts table database.

  Next, each component included in the used component / automatic placement key file is processed. First, as shown in FIG. 12B, the item number of the first part is written in the work process parts table database. Further, the level corresponding to the automatic placement key is obtained with reference to the template. Then, “1” is added to the obtained level, and the added level value is written in the work process parts table database.

  Here, the meaning of the above level processing will be described. In this embodiment, a level corresponds to a process, and the level is processed as information representing a process using this correspondence. If there are a plurality of processes at the same level, it may be further determined from the information of the parent process which process the part belongs to. In the above processing, “1” is added to the process level. The reason for this is as follows.

  FIG. 13 shows a hierarchical structure of a process parts table and a template for creating the process parts table. In the hierarchical structure, level 1 is a manual insertion process. The manually inserted part is classified into level 2 which is one level lower on the process parts table. As a result, the manually inserted part is positioned on the same level as the process below the manual insertion process on the process parts table. The relationship between other processes and parts is the same. By such level division, the process name and the vertical relationship of the parts used in the process are shown. In this embodiment, “1” is added to the level number obtained from the template in order to assign the level number according to the above rule.

  Returning to FIG. 12, all the remaining parts of the used parts / automatic arrangement key file are processed in the same manner. As a result, as shown in FIG. 12C, the item number and level are written in the work process parts table database. The parts table obtained in this way is called a work process parts table. When the work process parts table is generated, a process part table is generated. The process parts table is generated on the process parts table database as follows.

  FIG. 14 shows a process parts table database. All items in the work process parts table database are output to the process parts table database. At this time, all items are rearranged in the order of high process level. Thereby, components are arranged according to process levels. In the same process level, the item number created from the process name is arranged last.

  The rearrangement is performed by the sort processing unit 112 of the process parts table generation server 18 in FIG. The process parts table is a rearrangement of the data of the work process parts table, and thus is shaped, but is substantially the same as the work process parts table.

  FIG. 15 is a flowchart showing the work process parts table and the process parts table generation process. First, the template selected by the template selection unit 108 is read into the memory of the process parts table generation server 18 (S10). The process name of the template is converted into an item number, and the item number and level are output to the work process parts table database (S12). The parts data is read one by one from the used parts / automatic arrangement key file of FIG. 8 (S14). It is determined whether or not the processing of all component data has been completed (S16), and if not completed, the data of the target component is processed (S18). In S18, the template is referred to and a process corresponding to the automatic placement key of the target part is obtained. If the process is found in S18 (if the automatic placement key for the target part exists in the template), the collation result is OK in S20. If the collation result in S20 is NG, an error is displayed (S22).

  If the collation result is OK in S20, 1 is added to the level of the corresponding process in the template, and the added level is written in the work process parts table database together with the item number (S24), and the process returns to S14.

  If it is determined in S16 that all parts have been processed, the process proceeds to S26. Then, all data (all parts data) are read from the work process parts table database in the order of “level” and “item number”, and all data are output to the process parts table database. Thereby, the data of the work process parts table is rearranged, and the process parts table is generated.

  FIG. 16 shows an overall image of the process parts table generation process of the present embodiment. FIG. 16A shows a part of the CAM file, and the CAM file includes item number and insertion type information. The CAM file itself is a file of CAM data conventionally generated for a CAM system. However, in the present embodiment, the CAM file is used not only for the CAM system but also for generating the process parts table. That is, the process is obtained from the insertion type of each part of the CAM file using the automatic arrangement table of FIG. 16B and the template of FIG. Specifically, the insertion type is converted into an automatic placement key, and a process corresponding to the automatic placement key is obtained from the template. Then, the item number of each part is assigned to the determined process. Thereby, a process parts table as shown in FIG. 16D is generated.

  Here, as already described, the item number indicates a part constituting the circuit board and corresponds to the part identification information. The insertion type indicates a mounting machine used for mounting each component in the CAM system, and corresponds to mounting machine identification information of the present invention. In the automatic arrangement table, the automatic arrangement key is set differently for each process and corresponds to the intermediate code of the present invention. Further, the template associates an automatic placement key, which is an intermediate code, with a process, and therefore corresponds to the intermediate code process correspondence information of the present invention. Further, the automatic placement table (stored in the board CAD server 14) and the template (stored in the process parts table generation server 18) together form an insertion type as mounting machine identification information. And correspond to the process determination reference information of the present invention. The automatic arrangement table storage unit 90 of the board CAD server 14 and the template master storage unit 104 of the process parts table generation server 18 cooperate to correspond to a process determination reference information storage unit that stores process determination reference information. Yes.

  Therefore, according to the present embodiment described above, the mounting machine identification information included in the CAM data is extracted, the process corresponding to the mounting machine identification information of each component is obtained with reference to the mounting machine process correspondence information, The part identification information of each part is assigned to the obtained process, and thereby a process parts table is generated. In this way, paying attention to the conventional mounting machine identification information of CAM data, by using CAM data well, it is possible to automatically generate a process bill of materials without building a system from scratch. A suitable system for generating a bill of materials can be easily realized.

  In addition, according to the present embodiment, the process determination reference information includes information of a hierarchical structure that expresses the level of each process, thereby providing a process parts table that also expresses the process level. In the above-described embodiment, the hierarchical structure is included in the intermediate code process correspondence information (process part table generation template) constituting the process determination reference information.

  Further, according to the present embodiment, a plurality of types of process discrimination reference information having different hierarchical structures are prepared, and process discrimination reference information suitable for the circuit board to be processed is selected from the plurality of types of process discrimination reference information. Is done. Therefore, it is possible to generate a process parts table representing a plurality of types of hierarchical structures, and to provide a process parts table suitable for various circuit boards.
