This numerical control data creation device includes a data input unit 1, a data storage unit 2, a line data decomposition unit 6
And a control data conversion unit 4 and a data output unit 5.

The data input from the data input unit 1 is
The data is stored in the data storage unit 2 composed of a storage medium. The line data decomposing unit 6 determines whether the input data is a point or a line. If the input data is a point, the point data is output to the control data converter 4 as it is. When the input data is line data, the line data is continuously converted into continuous data of round holes partially overlapping, and the continuous data is transmitted to the control data conversion unit 4. Output.

The control data conversion unit 4 converts the data into data necessary for controlling the NC drilling machine and stores the data in the data storage unit 2. When the conversion of all data is completed, the data output unit 5 reads the data from the data storage unit 2 and outputs numerical control data for the NC drilling machine. Example 2 FIG. 5 is a block diagram showing another example of a conventional numerical control data creation device.

The numerical control data creation device has a data input unit 1, a data storage unit 2, a selection unit 3, a control data conversion unit 4, a data output unit 5, and a line data decomposition unit 6. I have.

The data input from the hole data input unit 1 is stored in the data storage unit 2. The selection unit 3 reads the data from the data storage unit 2, and outputs the data to the control data conversion unit 4 as it is if the data is point data, and outputs it to the line data decomposition unit 6 if the data is line data.

The line data decomposing unit 6 decomposes the straight line from the start point to the end point into a large number of round holes at a designated pitch, calculates the position coordinates thereof, and outputs the data to the control data conversion unit 4. The process after the control data conversion unit 4 is the same as in (Example 1).

[0008] In the above prior art, line data is linked.
Although it has the function of decomposing the connection hole, which is decomposed in the reverse communication
There is no means to convert the continuous hole data to the original line data. Therefore,

[0009]

The conventional numerical control data generating apparatus has a function of decomposing line data into points, but conversely, means for converting the decomposed continuous hole data into original line data is not available. Absent. Therefore, when it is necessary to change the line data decomposition standard in accordance with the change of the manufacturing specifications, the line data is added to the position of the converted continuous hole data, and these continuous hole data are added. Work to delete the data. Also, regarding CAD output data, since line data is decomposed and output by a method unique to each CAD machine, it is necessary to similarly modify line data for CAD machines having different specifications. As a result, there is a problem that the work time for creating drilling data increases.

[0017]

The gist of the present invention is a means for judging a characteristic long hole in a printed wiring board from input point data;
Characterized by Rukoto to have a means that converts them to the line data, i.e., not only means for creating decomposed and the point data from the line, to have the means to create a line data from a deconstructed data reversed Thus, even if the line data decomposition standard is changed, the line data can be immediately returned to the line data, and data corresponding to the new line data decomposition standard can be created, thereby shortening the data creation operation time.

[0019]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an example of a numerical control data generating apparatus according to the present invention.
The same reference numerals as in the block diagram of the prior art (Example 2) denote the same elements, and a detailed description thereof will be omitted.

In the numerical control data generating apparatus of the present invention, in addition to the conventional technique (Example 2), a function of selecting a continuous hole portion in which a plurality of holes having the same diameter overlap and form a row is added to the selecting unit 3. In addition, when this is the case, a line data generating unit 7 for converting the continuous hole portion into line data is provided.

Normally, holes in a printed wiring board do not overlap, and if a plurality of holes having the same diameter overlap and form a row, it can be determined that the hole is a long hole.

The data input from the data input unit 1 is output to the data storage unit 2. The data input unit 1 also inputs an instruction indicating whether line data is to be decomposed or, conversely, line data is to be generated from continuous holes.

The selection section 3 operates according to the input instruction. For example, in the case of a line data disassembly instruction, if the input data is point data, it is output to the control data conversion unit 4 as it is, and if it is line data, it is output to the line data decomposition unit 6. The line data decomposing unit 6 decomposes the straight line from the start point to the end point into a number of points at a designated pitch, calculates the position coordinates, and outputs the position coordinates to the control data conversion unit 4.

On the other hand, when the input instruction is an instruction to create line data from a continuous hole, the selection unit 3 selects, from the input data, a group of point data having a plurality of overlapping rows of holes having the same diameter. This is output to the line data creation unit 7. The line data creation unit 7 converts this into line data and outputs it to the control data conversion unit 4.

Usually, the holes in the printed wiring board are not overlapped, and if a plurality of holes having the same diameter overlap and form a row, it can be determined that the hole is a long hole. Identify long holes.

The control data conversion section 4 and subsequent steps are the same as in the prior art (Example 2).

Next, the operation of the selection unit 3, the line data decomposition unit 6, and the line data creation unit 7 of the present invention will be described with reference to the flowchart of FIG.

The numerical control data generating apparatus according to the present invention, upon inputting whether or not a drilling data and a line data decomposition instruction are input,
According to the instruction, each process (Step 3, Step 3)
5) Execute the subsequent steps.

In the case of the line data decomposition instruction, it is determined whether or not the input data is line data (Step 3). If the input data is point data, the data is output as it is (Step 9). After decomposing into continuous hole data (Step 4), the data is output (Step 9).

On the other hand, in the case of an instruction to generate line data from continuous holes, data located in the vicinity of the input data is read (Step 5). It is determined that there is, and this is converted to line data (Step 7). If they do not overlap, the next peripheral data is read (Step 5). When the data at the peripheral positions has been completely compared, the converted line data is output (Step 9).

This series of processing is repeated until the input data is completed (Step 10).

[0033]

As described above, according to the numerical control data generating apparatus of the present invention, it is possible to not only decompose line data into points, but also to convert decomposed data into line data. Since it is easy to change the disassembly criterion, and it is possible to easily convert the CAD output elongated hole disassembled point data into line data, there is an effect that the data creation work time can be reduced.

Further, unlike the prior art, the line data is automatically generated from the decomposed data, so that the rate of occurrence of data defects such as numerical input errors can be reduced.
