Abstract

PURPOSE:To attain high speed and highly accurate program generation by inputting picture data fetched by a picture input device to a program generating processor after it is converted into vector data. CONSTITUTION:A picture is converted into an electric signal V by a TV camera 2A or a scanner 2B and subject to pre-processing including binarization, then stored in a picture memory 3. A picture processing processor 4 converts the picture data from the picture memory 3 into a vector data such as a profile data. A program generation processor 5 generates a work program from the vector data.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention inputs drawings, pictures, photographs, etc. using an image input device, processes the input images, converts them into vector data,
The present invention relates to a machining program creation device that automatically creates a machining (NC) program from this vector data.

[Conventional technology]

Conventionally, as this type of machine programming, it is known that the creator directly inputs data using a digitizer or the like.

[Problem that the invention seeks to solve]

However, this method not only requires a great deal of time for programming, but also has problems in that detailed work is difficult and it is difficult to create accurate programs.

Therefore, an object of the present invention is to provide a machine program creation device that can (a) reduce the time spent on machine programming and perform precise and accurate programming by automatically creating a machine program from images such as drawings. shall be.

[Means for solving the problem] - An image input device that captures image data, an image memory that stores image data, and performs predetermined processing based on the stored image data to at least convert the image data into vector data. An image processing processor that creates machine programs based on vector data, a program creation processor that creates machine programs based on vector data, and various input/output devices that serve as man-machine interfaces for the program creation processor are installed to automatically program machine tools. go to

[Effect]

Import image data such as drawings using an image input device,
After converting this into vector data using an image processing processor, a program creation processor automatically creates a work program, thereby increasing the speed and accuracy of program creation.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of the present invention.

In the figure, 1 is a drawing, 2A is a television (TV) camera, 2B is a scanner, 3 is an image memory, 4 is an image processing processor, 5 is a program creation processor, 6 is a keyboard, 7 is a mouse, 8 is a printer, 9 is display, 1
0 is the laser engraving control unit, 11 is the laser engraving machine,
Reference numeral 12 denotes a workpiece, and this is an example in which the same content as shown in FIG. 1 is automatically stamped on the workpiece 12 by the laser stamping machine 11. In addition, instead of the laser marking machine 11,
Needless to say, a machine tool similar to this can be used.

That is, the image shown in FIG. 1 is converted into an electric signal (2) by the TV camera 2A or the scanner 2B, and stored in the image memory 3 after being subjected to preprocessing including binarization. The image processing processor 4 performs various well-known image processing based on the image data from the image memory 3, and in this case, the image data is converted into vector data such as outline data. From this vector data, the program creation processor 5 creates a machining program such that the contents of drawing 1 are engraved on the workpiece 12 via the laser marking machine 11.

Here, an example of how to create a machining program from vector data will be explained. Now, vector data is the second
This is shown in Figure (a). It is assumed that the contour line data is stored in a table (not shown) as shown in FIG.

1) First, in order to move to the first starting point (a, b),
=a,b instructions are created.

2) Next, the command to draw a line to the end point (c, d), L
=Create c, d.

3) Since this end point (c, d) and the next starting point (c, d) are the same point, no command is created.

4) Instruction to draw a line to the next end point (e, f), L=
Create e and f.

Below, create a program using the same procedure. The resulting program, in the example of FIG. 2, is as follows.

J=a, b L=c, d L=e, f L=g, h L=i, j In the above, L indicates the command to move while drawing a line (while doing the work), and J indicates This is an instruction to move only the laser head or drill without doing any work. In addition, in the above item 3), if the end point and the next starting point are not equal, J = c', d'(c', d
' is the next starting point).

The program created in this way is given to the laser engraving control section 10, and the laser engraving machine 11 is driven under the control of the laser engraving control section 10. It will be stamped.

In this case, if a data flow type (non-Neumann type) processor is used as the image processing processor 4 instead of the currently mainstream so-called Neumann type processor, faster image processing operations can be performed. can. In addition, by using a human-powered device such as the keyboard 6 or mouse 7, it is possible to perform image editing such as rough image processing and cropping, including noise removal on image data, and image processing, cropping, insertion, correction, etc. on vector data. Delete, move.

It is possible to edit data such as transcription, and edit created work programs. On the other hand, by using the printer 8 and display 9, it is possible to visually view image signals (binary images), vector data, or work programs.

〔Effect of the invention〕

According to the present invention, since programming that has conventionally been done manually is automated, the advantage of speeding up program creation and increasing accuracy is brought about. Further, if a data flow type processor is used as the image processing processor, programming can be performed at higher speed. Another advantage is that image data, vector data, and machining programs can be edited very easily using the input/output device.
