Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for supporting product design, and in particular, at the final stage of design, creates and displays work procedures such as assembly order of parts and test procedures based on assembly drawings. The present invention relates to a device for calculating work time and evaluating workability of a designed product.

A conventional method for instructing an assembly work order of a product composed of a plurality of parts is to use a process analysis symbol with reference to a parts composition table created by a designer and a result of assembling a prototype. A general method is to create a work order table, and a general method for calculating the working time is to estimate the working time using a previously created work time table.

However, the work procedure manual is often created by a person different from the designer, and if the work procedure is not well known, it takes a lot of time to create the work procedure manual. In addition, although the assembly sequence is shown in the work sequence table created by the existing process analysis method, there is a problem that it is difficult to understand the detailed work method and the difficulty level of the work, and when calculating the work time. There is a problem in that it takes a lot of time to estimate when the number of parts is large.

Under the above circumstances, the designer himself can easily create and register the assembly sequence and the test sequence of the parts, and the work time can be calculated and evaluated. A device is desired.

[0005]

2. Description of the Related Art A work sequence table created by a conventional process analysis method will be described in detail with reference to FIG.

FIG. 9 is a diagram showing an example of a conventional work sequence table. In the work sequence table shown in FIG. 9, a process analysis symbol ▽ indicating a part, a process analysis symbol ▼ indicating a unit, and a process analysis symbol ◯ indicating a work are arranged from the upper side to the lower side in a process line order, and a work name, for example, Placement, fitting, screw tightening, tape adhesion, etc. are entered, and parts to be put in during the work are added to this process line.

FIG. 9 shows that the component A is placed by the placing work, and the component B and two screws are attached to the component A and fixed by the screw tightening work. The component G is placed by the placing work, the component H is attached to the component G and fixed by the tape bonding work, and the unit 3 is attached.
It shows that it becomes.

After the component D is placed by the placing work, the unit 3 is attached to the component D, and the fitting work becomes the unit 1, and the unit 1 and one screw are attached to the component A and the screw tightening work is performed. It is shown to be fixed to the part A.

Similarly, it is shown that the parts E and F become the unit 2, and the unit 2 and two screws are attached to the part A and fixed to the part A by the screw tightening work.

[0010]

The conventional work sequence table described above is often created by a person other than the designer.
It takes a lot of time to create it because it is not familiar with the work content, and even though the assembly sequence is known by the conventional process analysis method, it is necessary to fully understand the detailed work method and the difficulty level such as the work time. In many cases, there is a problem that a large number of parts requires a large number of man-hours to calculate the working time.

In view of the above situation, the present invention registers the work name and work condition corresponding to the part name and the unit name, and registers the work time and the work time corresponding to the work name. The purpose of the present invention is to provide a work procedure creation / evaluation apparatus and a work procedure creation / evaluation method capable of displaying these contents and performing evaluation.
