DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process management system for performing a work by arranging a number of component mounting lines.

[0002]

2. Description of the Related Art An example in which a computer controls a mounting line constituted by combining a component mounter and its peripheral devices can be seen in Japanese Patent Application Laid-Open No. 2-1505.

[0003]

When there are a plurality of mounting lines, in order to carry out work efficiently by utilizing the entire mounting line group, it is necessary to equalize the load on the mounting machines constituting each line. It is necessary to appropriately divide the NC data per board and allocate it to the mounting machine. Until now, such an allocation operation has been manually performed by a worker using a personal computer, and the work has been sent from the personal computer to each mounting machine. Therefore, if the equipment composing the mounting line changes, it is necessary for the operator to change the division mode accordingly.
There was a problem that data could not be created. Further, depending on the substrate, it is necessary to perform a coordinate input operation of thousands of steps, and the burden on the operator is enormous. In addition, since the mounting data created with great care is also stored on a floppy disk for each mounting machine, the integrated data cannot be managed centrally. The present invention seeks to solve these problems.

[0004]

According to the present invention, a single centralized management computer manages a plurality of line management computers for managing a mounting line configured by combining a component mounting machine and its peripheral devices.

[0008]

An embodiment will be described with reference to the drawings. In FIG. 1, 1 is a LAN (local area network),
2, 3, and 4 are mounting lines connected to the LAN 1.
The mounting lines 2, 3, and 4 are for mounting electronic components on an electronic circuit board, and each includes a plurality of machines (mounting machines and peripheral devices) 5 and a line management computer 6 for managing these. Consists of Reference numerals 7 and 8 denote a CAD (Computer Aided Design) system and a centralized management computer which are also connected to the LAN 1. Centralized management computer
8 is a line configuration file 9, a production plan file 10,
A mounting data file 11 and a part library 12 are attached. The line configuration file 9 stores specific data such as the type and function of the machine 5 that forms the mounting line. The production plan file 10 stores a production plan for each mounting line. The mounting data file 11 stores data relating to the component mounting pattern created by the CAD system 7. The part library 12 stores data unique to the component, that is, data such as types, dimensions, and shapes.

The system functions as follows. First, the operator makes a daily production plan on the central control computer 8. At this time, the operator inputs the board loading time, the number of boards to be produced, the mounting data file name, and the like. Then, the central management computer 8 searches the line configuration file 9 for a mounting line provided with a machine capable of mounting all kinds of components in the mounting data. If a plurality of mounting lines are extracted by the search, the production plan file 10 is checked, and the current production plan is added to a line having a margin.

Next, the mounting data registered as what is to be executed by the production plan processing program of the central control computer 8 is transferred from the CAD system 7 to the central control computer 8 online. The transferred data is stored in the mounting data file 11.

Next, on the centralized management computer 8, the work of dividing the mounting data so that the working time of each mounting machine becomes equal is automatically executed based on the program. This is performed with reference to the line configuration file 9. Thus, NC data for each mounting machine is created and allocated.

At the time of the NC data creation operation, an image as shown in FIG. 2 appears on the monitor-display of the central control computer 8. In this example, the component shape is displayed according to a predetermined mounting pattern, and the mounting locus is indicated by a line. The imaging of the parts is performed based on the data registered in the parts library 12. Therefore, the component image accurately represents the shape in a dimensional relationship proportional to the actual size, and can be checked even if the wrong component is CAD-input. In addition, since the interval between the components can be automatically calculated, the component is displayed in a different color when the components collide. This allows the operator to find a CAD design error. If a mistake is found, the operator uses the keyboard of the central control computer 8 to correct the implementation data. When checking a place where small parts are concentrated, a part in the upper left image in FIG.
Can be enlarged and displayed as in the lower right image.

Next, the line management computer 6 of the mounting line incorporated in the current production plan is
The data is received from the central management computer 8 and transferred to each mounting machine on the mounting line.

The above-mentioned mounting machine group starts the production of the board based on the NC data, and transmits the result data obtained in the production process to the line management computer 6 at regular intervals. The line management computer 6 transmits the result data of the entire mounting line to the centralized management computer 8. If a defect is found in the board design during actual production, the mounting machine can correct the mounting data.

After the production of the board is completed, the line management computer 6 collects the final production result data from each mounting machine and sends it to the centralized management computer 8.

The central management computer 8 can display the result data transmitted from the line management computer 6 in real time. The received data is stored.

In this system, when the mounting data is modified on the mounting machine side, the NC data on the mounting machine side and the NC data on the centralized control computer 8 are prevented from being discrepant with each other. After the completion, the line management computer 6 sends the NC from the mounting machine.
The data is collected and transmitted to the central management computer 8.
The centralized management computer 8 updates the mounting data file 11 based on the received data.

As described above, the centralized management computer 8 centrally manages the mounting data and the actual data after mounting, thereby facilitating the maintenance and inspection of the data.

[0019]

As described above, according to the present invention, the NC data for each mounting machine is automatically created in consideration of the line load, so that the best NC data can be created even by a non-expert. In addition, since the centralized management computer can refer to its own line configuration file and select an optimum line from among a plurality of mounting lines and transfer the NC data to the line management computer, the work efficiency of the entire mounting section can be improved. In addition, if the mounting data is corrected on the mounting machine side, the effect is extended to the centralized management computer, and a trouble caused by a difference in data between the two can be prevented. In addition, a component check can be performed on a display of a centralized management computer, and a component mounting path can be checked, a type can be checked, and a collision can be checked without actually performing a test hit.
