Abstract

PURPOSE:To correctly carry out read and write of data by reading laser beam machining control data from a storage medium and writing these data in a storage region after a program starting and reading the laser beam machining control data of the storage region and writing these data in the storage medium after machining finishing. CONSTITUTION:After the program starting, the data stored as a file A in the storage medium 3 are read and these are written in the storage region 2. As necessary, the data are read to change the data from a key input device 1 and A CPU 4 outputs a laser beam from a laser beam oscillator 8 and performs machining based on the data. When an input key of the key input device is a finishing key, the data from the storage region 2 are read and the data are written as the file A in the storage medium 3 to finish the program. By this method, processing of read and write of the data from the storage medium is carried out correctly without depending on human key operation and the time can be saved by adding processing to write in the storage medium as the file A.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a laser processing device, and in particular, to
The present invention relates to a method of processing laser processing control data for controlling movement of a Yθ stage and controlling laser power.

[Conventional technology]

Conventionally, in all processing methods of this type, humans specify the laser processing control data (hereinafter referred to as "data") that they wish to read before processing using operations such as key input, and execute the readout to process the data using that data. Similarly, at the end of the process, the data used by a person can be written to a storage medium through operations such as key input, so that the data can be read and used at a later date.

[Problem to be solved by the invention]

In the conventional processing method described above, it is necessary to read the data by specifying the file name using key input or other operations before processing, and also to read out the data by specifying the file name at the end of processing. It is necessary to perform the process of exporting the data to a computer, which is time-consuming.

In addition, if you forget to write the data used at the end to the storage medium, even if you try to process the same data later, it will not be stored, so you will have to take the time to set the conditions again and obtain the data. For example, if you perform the export process but forget the name of the exported file, the disadvantage is that you have to read and confirm the data over and over again until you want to read the data you want to use at a later date.

[Differences between the invention and the prior art]

The present invention differs from the conventional data processing method described above in that the apparatus automatically performs the processing.

[Means to solve the problem]

The present invention includes a laser oscillator that outputs a laser beam, an optical system that controls laser power, an XYθ stage that moves a workpiece under the laser beam, a storage medium that stores data, and a storage medium that stores data. In a method for processing laser processing control data of a laser processing device that performs laser drawing using a key input device for inputting instructions, etc., after the program starts, the data is stored as a specific file (referred to as file A) from a storage medium. A first step of reading data and writing it into a storage area, and a second step of detecting an input key from the key input device and determining that it is an end key after initializing the device and completing the laser processing process. , has a third step of reading the laser processing control data in the storage area when the input key is the end key, and writing it as file A to the storage medium.

〔Example〕

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

FIG. 1 is a block diagram of an embodiment of the present invention. In the embodiment of the present invention, after starting the program, data stored in the storage medium 3 as file A is read out and stored in the storage area 2.
The CPU 4 reads data to change the data from the key input device 1 as necessary, and controls the laser power of the optical system 7 of the main body 5 based on the data.
The Yθ stage 6 is moved, and the laser oscillator 8 outputs laser light for processing.

FIG. 2 shows the procedure for processing data by the CPU 4. The outline is that when the program starts, the first step is to read the data stored as file A in the storage medium 3 (step 12), and write that data to the storage area 2 (step 13). , initialize the device (step 14). Next, it is determined whether there is a data change request (Step 15), and if there is, the input data is detected from the key input device (Step 16).
, write the data to the storage area (step 17),
Next, laser processing (step 18) is performed based on the data, and when the laser processing is completed, the second step is to detect an input key from the key input device (step 19), and the input key is the end key. If it is not the end key, the process returns to step 15.

In the case of the end key, the third step is to read data from the storage area (step 21), and write the data to the storage medium as file A (step 22).

Finally, the device is terminated (step 23), and the program is terminated.

FIG. 3 shows a data processing procedure by the CPU 4 according to the second embodiment of the present invention. The outline is almost the same as that of the first embodiment, and only steps 41 to 43 are different. That is, in the second embodiment, when the end key is pressed, a message asking whether to write data to the storage medium 3 is output (step 41), an input key is detected from the key input device (step 42), and the input key is output to write data. If the key specifies writing, the process of writing the data to the storage medium (steps 44 and 45) is executed; if not, the process executes step 4.
Now move on to the device termination work in step 6. That is, in this example,
By adding a function that outputs a question message before automatically writing data as in Example 1 and allowing you to select whether or not to write the data to a storage medium, it will not be written if it is not necessary. Further, depending on the case, there is an advantage that the data from the previous time can be used as is the next time the data is used.

〔Effect of the invention〕

As explained above, the present invention is a data processing method that includes the process of reading data stored as file A from a storage medium after starting a program and writing it to a storage area, and the process of inputting an end key using a key input device after finishing a laser processing process. If detected, the data in the storage area is read out,
By adding the process of writing the data to the storage medium as file A, the process of reading and writing data from the storage medium, which humans always had to perform by keystrokes before and after finishing work, can be done without fail, saving time and effort. This has the effect of saving money.
