Abstract

PURPOSE:To input automatically graphic data with good accuracy by the constitution in which an optical reader is used for inputting of the graphic data for laser working and a recognizing part for recognizing the coordinates and shape according to said data is provided. CONSTITUTION:A graphic is read with an optical reader 8 such as a facsimile or the like and is graphically approximated by a straight line of arc so as to attain prescribed accuracy according to said data by a recognizing part 9. The graphic is then converted and outputted by a data converter 3 to the shape which an NC device 2 can recognize. The device 2 drives an X-Y table 4 according to the command from the converter 3 and controls the relative position of the laser light 6 outputted from a laser oscillator 5 and the material 7 to be worked thereby working the desired graphic.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention facilitates the manual effort of one figure data when cutting a proboscis into a five-line figure using a laser cutter. This relates to a laser processing device V.

CIE Prior Technology] Conventionally, there was a laser processing device of this type as shown in Fig. 1. FIG. 1 is a block diagram showing a conventional laser processing apparatus. In the figure, 1 is a digitizer for inputting graphic data, 2 is NO (numerical control)
3 is a data conversion device that converts graphic data input from the digitizer 1 into data that can be recognized by the NC device 2; 4 is an NC device? 4. An XY table driven by 2, 5 a laser oscillator, 6 a laser source, 7 a laser source 6
It is a f leather sword that explodes with 11 powers.

Next, the operation of the conventional laser processing device 1 shown in FIG. 1 will be explained. For example, let us consider the case of processing an example of a figure as shown in Figure WJ2. Place the figure shown in Figure 2 on top of the digitizer 1, use the stylus pen to hit the position of the black circle shown in Figure 3, and place the figure between the hit point and the point (f- itii
:Create a figure while inputting the information that it will be connected by a line or arc.

The graphic data that has been manually processed by the digitizer 1 is converted by the data conversion device 3 into data that can be read by the 9NC device 2. The NC device 2 moves the XY table 4tl-fg71 based on the command from the data conversion device 3, and controls the relative position between the laser beam 6 output from the laser oscillator 5 and the workpiece 7. It is possible to process desired shapes.

Conventional laser processing equipment is constructed as described above, so when processing the workpiece 7fc into an arbitrary shape, the figure is placed on the digitizer 1 and each point of the figure is manually traced. In addition, there is a drawback that the accuracy of the input position varies depending on the operator. In reality, the variation in position accuracy is 0.5 rrWI
Sometimes the degree also varied.

[Summary of the invention]

This invention was made with the aim of improving the drawbacks of the conventional ones as described above, and uses a Kyushu reading device to input the graphic data for performing laser sword loe, and based on the read data. To provide a laser processing device which has a configuration including a recognition unit that recognizes the coordinates and shape t-of the object, and which enables the manual processing of figure data automatically and with high accuracy without the need for human intervention. .

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 is a block diagram showing a laser processing apparatus which is an embodiment of the present invention. The same parts as those in FIG. In the figure, 8 is a device such as a facsimile machine that reads the shape of the figure to be processed on the drawing, and 9 is a coordinate system based on the data read by the device 8. and a recognition unit for recognizing shapes. Other leased land, except for the digitizer l shown in Figure 1 above, is
The structure is similar to that shown in the figure.

Next, the operation of a laser processing apparatus which is an embodiment of the present invention, which is not shown in FIG. 4, will be described. Consider the case where an example of a figure as shown in FIG. 2 is to be modified in the same way as in the conventional reli described above. Instead, the shape of the figure as shown in FIG. 2 is read using a digital camera 4/receiving device 8 such as a facsimile machine.

At this time, the glare removal accuracy can be expected to be approximately 80 μm.

Based on the data obtained by the bladder cooling device 8, the recognition unit 9 approximates the shape of the above-mentioned figure with a straight line or an arc so as to achieve a predetermined accuracy. Thereafter, the data converter 3 converts the data into a format that can be recognized by the NC equipment 2 and outputs it. The NC device 2 pivots the XY table 4 based on the command from the data conversion 4Qf (3) and controls the relative position between the laser source 6 output from the laser oscillator 5 and the broken object 7. It is possible to process desired shapes.

In addition, by providing the recognition unit 9 with a dialogue correction function,
Interactive modification of the read data is also a tiJ capability.

〔Effect of the invention〕

As explained above, this invention is configured so that the manual labor of graphic data for laser processing can be automatically performed in a laser processing device. This provides an excellent effect in that graphic data can be entered unattended and with extremely high accuracy without any manual operations.
