Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an NC program creating apparatus for a component mounter which creates an NC program for a component mounter that mounts components on a printed circuit board.

[0002]

2. Description of the Related Art Conventionally, an NC program for a component mounter has been performed by simply editing characters of CAD data.

[0003]

However, CAD is actually used.
There is usually a discrepancy in the mounting data between the data and the component mounting machine, and in order to correct the discrepancy, the above method of editing characters is a very careful and time-consuming task. Sometimes, mistakes occur due to the misunderstanding of the operator. In another method, the printed circuit board is displayed on the monitor screen, the XY stage on which the printed circuit board is placed is moved, and the reference position of the component to be mounted is moved to the position where the reference mark of the center of the screen overlaps with the coordinate. The data was picked up, and the mounting angle was a method in which the operator inputs a key. This method was also time consuming and error prone.

In view of such a point, the present invention displays an image of a printed circuit board on a CRT screen, and forms a directional graphic in a form of being superimposed on the image according to the component mounting position data and direction data of CAD data. By visually displaying, the correctness of the CAD data can be judged at a glance, and when the printed circuit board and the CAD data do not match, the component mounting position and direction of the CAD data can be corrected more easily. The purpose is to provide a device.

[0005]

In order to achieve the above object, an NC program creating apparatus for a component mounting machine according to the present invention is mainly composed of a printed circuit board image image input means, a CAD data input means, and both images. Display means and CAD
It comprises a data correction means, an NC program generation means, and an NC program output means.

[0006]

With the above structure, the consistency between the CAD data and the printed circuit board can be easily confirmed and corrected, and the NC program can be easily created even by a person who is not familiar with how to use the mounting machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of the program creating apparatus. Here, it is assumed that the Gerber data of the substrate silk extracted from the printed circuit board CAD is used as the image image of the printed circuit board, and the operation will be described below. The Gerber data of the substrate silk extracted from the printed circuit board CAD is loaded into the apparatus by the printed circuit board image image input means 1. This data is stored in the image image storage means 2.
Remembered in. The stored data is displayed on the display device by the image image display means 3.

Next, C extracted from the printed circuit board CAD
The AD data is taken into the device by the CAD data input means 4. This data is stored in the CAD data storage means 5. The stored data is displayed on the display device by the CAD data display means 6. The screen image display means 7 superimposes the displayed image image (drawing of the board silk) and the parts layout drawing (the parts are indicated by arrows) displayed according to the CAD data. By overlapping, the mounting position and mounting direction of components can be compared at a glance.

Next, if a mismatch is found as a result of the comparison, the CAD data must be changed to match the substrate silk. For this purpose, first, the non-matching parts are instructed to the apparatus (this system) by using the part selecting means 8. The CAD data corresponding to the instructed part is corrected using the data correction means 9. For example, when the component mounting directions do not match, the mounting angle correction means 10 is used to
The mounting angle data of the AD data is corrected so as to match the board silk. The result of this change is reflected on the display, and the board silk and the component mounting direction can be seen to match. If the component mounting positions do not match, the mounting position coordinate data correction means 11 is used to correct the mounting position coordinate data of the CAD data so as to match the board silk. The result of this change is reflected in the display, and the board silk and the component mounting position can be seen to match. Further, when the coordinate data of the CAD data is displaced by the same amount as a whole, the overall coordinate shift means 12 changes the entire coordinate by the amount of the shift, and the substrate silk and the component mounting position are changed. To match. Further, since this device is premised on the perspective of the component surface (front surface), it is necessary to reverse the front and back for the component mounted on the solder surface (rear surface) side. Therefore, the CAD data of the solder side component viewed from the component side must be changed by the general coordinate mirror image changing means.

As described above, the parts are inspected one by one, and the correction work is carried out so that the board silk and the part layout diagram match. Based on the modified CAD data,
The NC program is generated by using the NC program generating means 14. The generated NC program is stored in the NC program storage means 15. Finally, the NC program output means 16 outputs the NC program. The output medium is
A device compatible with the target mounting machine is prepared. For example, there are floppy disks, paper tapes, and the like. The above is the outline of the present apparatus.

Next, details will be described with reference to the drawings. FIG. 2 shows an example of a graphic indicating the mounting position and direction. The point 201 where the two straight lines intersect corresponds to the reference point of the part. The mark Δ indicates the mounting direction of the component. In the case of this figure, the direction of 0 ° is shown. Angle directions are defined to move counterclockwise.

FIG. 3 is an enlarged view of components for mounting chip components on a printed circuit board. 301 is a terminal part for soldering components. 302 and 303 are silk printing. The component is mounted such that the center of the component overlaps the center of the two terminals.

FIG. 4 shows the appearance when a graphic having directionality is superimposed and displayed on a printed circuit board image. It can be seen that the component mounting positions are correct. It can also be seen that the component mounting directions are also correct.

FIG. 5 shows the appearance when a directional graphic is overlaid and displayed on a printed circuit board image. In this case, it can be seen that the component mounting positions are correctly aligned. However, it is easy to see that the component mounting direction is wrong. The cause of this disagreement is that the direction when defining the part data is wrong on the CAD side. In this case, the component mounting direction can be correctly changed by using the function of correcting the mounting direction and rotating the figure having the direction by + 90 ° in the counterclockwise direction. The appearance after this change is as shown in FIG. 4, and it is obvious that the change was correct.

FIG. 6 shows an example of CAD data. From the left side, the circuit number, X-coordinate, Y-coordinate, and mounting angle are shown. In addition, a symbol name and a part shape name may be included.

[0017]

As described above, according to the present invention, by displaying a graphic having directionality on a printed circuit board image, an operator can adjust the direction and position of the CAD data without thinking. Since the mounting position and mounting direction of the printed circuit board can be easily confirmed and corrected, an NC program can be easily created without error. Compared to the conventional method, there is no error due to misunderstanding by the operator and the operation is simple, so that even an person who is not familiar with how to use the mounting machine can easily create an NC program.
