For example, when a facility reviewer examines the assembly process S1 for a specific vehicle type, the user enters “Assembly process S1” in the “Review assembly process information” on the screen of the display 4, A specific vehicle type is input in “vehicle type information” (see FIG. 4). When the “Installation Review” button is pressed, the search system unit 23 stores the CAD data file of the production equipment M1 used in the assembly process S1 and the CAD data file of the base part by the CAD system unit 22. A predetermined read origin is read from the unit 21 and the figure 51 of the production facility M1 and the figure 52 of the base part are displayed on the display 4 (see FIG. 8).

Further, the search system unit 23 uses the CAD system unit 22 to generate the CAD data files of the parts A2 to A5 constituting the sub-assembly B1 to be attached to the base part in the assembly step S1 based on the sub-assembly data. A predetermined read origin is read from the data storage unit 21 and displayed on the display 4 as a figure 54 in a combined state as the sub assembly B1 (see FIG. 8). Furthermore, the search system unit 23 uses the CAD system file 22 based on the main assembly data as a base for the CAD data file of the part A1 constituting the single unit C0 already assembled to the base part in the assembly step S1. The parts are read together with the reading origin, and the unit C0 is displayed on the display 4 as a figure 53 in a state of being combined with the base part (see FIG. 8).
In this way, the facility examiner conducts the assembly examination of the sub assembly B1 (parts A2 to A5) on the base part on which the single unit C0 (part A1) is assembled on the display 4 in the assembly step S1. Can do.

  Further, for example, when an equipment reviewer examines the assembly of the sub-assembly process T1 for a specific vehicle type, the "assembling process S1" is input in the "examination assembly process information" on the screen of the display 4. Then, a specific vehicle type is input in the “reviewed vehicle type information” (see FIG. 4). Then, when the “Assembly Review” button is pressed, the search system unit 23 reads the CAD data file of the sub-production facility N1 used in the sub-assembly process T1 from the data storage unit 21 by the CAD system unit 22. The figure of the sub-production facility N1 is displayed on the display 4. In addition, on the screen of the display 4 in FIG. 4, the examination sub-production equipment information of this example includes information on “assembly process S1” input in “review assembly process information” and “assembly review”. This information is combined with the information of pressing the button.

The search system unit 23 also converts the CAD data file of the parts A2 to A5 constituting the subassembly B1 to be assembled in the subassembly step T1 by the CAD system unit 22 based on the subassembly data, to the data storage unit 21.

Thus, the facility examiner can perform the assembly examination of the sub assembly B1 (parts A2 to A5) on the display 4 in the sub assembly process T1.

  The search system unit 23 performs the same operation as the assembly step S1 for the assembly steps S2 to S4, and performs the same operation as the sub-assembly step T1 for the sub-assembly step T2. For example, when an equipment reviewer examines the assembly process S4 for a specific vehicle type, enter “assembly process S4” in the “review assembly process information” and specify it in the “reviewed vehicle type information”. Enter the vehicle type. When the “Installation Review” button is pressed, the search system unit 23 stores the CAD data file of the production facility M4 and the CAD data file of the base part used in the assembly process S4 by the CAD system unit 22. A predetermined read origin is read from the unit 21 and the figure of the production facility M4 and the figure of the base part are displayed on the display 4.

Further, the search system unit 23 obtains the CAD data file of the part A9 constituting the single unit C4 to be assembled to the base part in the assembling step S4 from the data storage unit 21 based on the sub-assembly data. It is read and displayed on the display 4 as the figure of the single C4. Further, the search system unit 23 is based on the main assembly data, and the CAD system unit 22 uses the unit C0, the sub assembly B1, the unit C2, the sub assembly already assembled to the base part in the assembly step S4. The CAD data file of the parts A1 to A8 constituting the attachment B3 is read with the base part and the reading origin aligned, and the single unit C0, the sub assembly B1, the single unit C2, and the sub assembly B3 are integrated with the base part. It is displayed on the display 4 as a combined figure.
In this way, the facility examiner, for the assembly step S4, single C0 (part A1), sub-assembly B1 (parts A2 to A5), single C2 (part A6), sub-assembly B3 (parts A7, A8). Assembling examination of the single unit C4 (part A9) to the base part assembled with can be performed on the display 4.

In this way, the facility reviewer inputs the study assembly process information as the assembly processes S1 to S4 from the input unit 3, so that the CAD necessary for examining the production facilities of each assembly process can be easily and quickly performed. The data file can be read into the CAD system unit 22 and displayed on the display 4 as a graphic. Then, the facility examiner confirms whether or not the sub-assembled body can be assembled in each assembling process, assembling performance, etc., whether or not the sub-assembled body can be assembled to the base part, Performance etc. can be examined.
In particular, the base part graphic 52 displayed on the display 4 can be displayed in a state where the already-assembled part graphic 53 is also combined, and the possibility of assembly, assembly performance, etc. are examined. Can be performed more accurately (see FIG. 8).

  Further, in the facility examination support system 1 of this example, a plurality of sub-assembly processes (sub-assembly processes T1 and T2 in this example) and a plurality of assembly processes (assembly processes S1 to S4) are collectively performed. Can be managed. In particular, when there is a change in vehicle specifications, production equipment, production line, etc., it is very easy and quick to repeat production by replacing each CAD data file with the one after the change. The equipment can be examined. For this reason, it is possible to remarkably shorten the examination time for the production facility and the sub production facility of the facility examiner.

  Therefore, according to the facility examination support system 1 of this example, it is possible to easily and quickly examine production facilities such as whether or not assembly is possible and assembly performance.
