Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to an improvement of an automatic programming device used for an automatic machine tool such as a laser beam machine or a robot.

[Technical background of the invention and its problems]

Generally, a control program for an automatic machine tool such as a laser processing machine or a robot includes a movement command that defines a so-called tool trajectory such as a laser beam or a robot hand, and a tool operation such as start or stop of laser beam output and robot hand. And a sequence command that defines the opening and closing of the. The locus is composed of a series of coordinate sequences, and the movement command is expressed by the movement amount from the current coordinate to the next target coordinate and the interpolation method. Then, prior to this movement command, a sequence command for defining the movement of the tool during movement or the movement to be completed before the movement and the movement speed is described. That is, in the control program, the sequence command and the movement command are written alternately, and two commands form one set to define the minimum program and generate the optimum control program.

However, the conventional automatic programming device merely intends to automatically generate a movement command, and is merely a mere motion trajectory drawing machine. In other words, a series of coordinates are registered, numbers are assigned to these coordinates, and movement commands are automatically generated by sequentially specifying these numbers, but the machining parameters are set by the operator in accordance with various trajectory conditions. It is necessary to describe each move command in a one-to-one correspondence. Therefore, the modification of the locus, that is, the modification of the movement command is easy because it only changes the designated order of the coordinate numbers, but all the machining parameters must be redefined by the operator. That is, the machining parameters must be reviewed and reset again from the beginning according to the movement order. As described above, if the machining shape is complicated, not only coordinate data, that is, a movement command becomes enormous, but also a sequence command corresponding to one-to-one also becomes enormous, and definition of a processing parameter that constitutes the sequence command is also increased. It becomes complicated and requires a great deal of time to complete one control program. After all, in the conventional automatic programming device, there is a problem that the movement command and the sequence command cannot be independently set independently.

[Object of the Invention]

The present invention has been made to solve the above problems, and its purpose is to independently register a movement command and a sequence command and automatically combine them to generate a control program extremely efficiently. An object is to provide an automatic programming device capable of performing.

That is, in the present invention, the movement command and the sequence command are independently registered, and these are combined, in other words,
The gist of the present invention is to generate a control program extremely efficiently by separately registering the programs by component elements (movement command and sequence command) and combining them, instead of separately storing a plurality of programs.

Hereinafter, a specific embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a configuration example of an automatic programming device according to the present invention. As shown in FIG. 1, the automatic programming device of the present embodiment is a graphic information management device 1 for storing CL data consisting of coordinate information forming a control program together with an identification number b added to each CL data. , A machining parameter memory 2 for storing a machining parameter and an identification number a added thereto, an identification number memory 3 for storing each of the identification numbers a and b in a one-to-one combination, the identification number a and the identification. Combination of number b,
CL data is read from the data input device 4 for registering the processing parameter and the identification number b and the graphic information management device 1, and the identification number b added to this and the corresponding identification number a are stored in the identification number storage device. 3 is searched and collated to read the machining parameter corresponding to the identification number a from the machining parameter storage device 2 and the identification number a.
Corresponding to the processing parameter corresponding to
A combination determination device 5 that synthesizes CL data, a control program generation device 6 that reads a pair of machining parameters and CL data from the combination determination device 5 and generates a control program under predetermined conditions, and this control program generation The control program storage device 7 stores and holds the control program generated by the device 6.

Next, the operation of the automatic programming device configured as described above will be described with reference to the flow charts shown in FIGS.

First, the control program generation device 6 is a so-called post processor that sequentially reads the processing parameters and the movement parameters and generates a control program. The processing parameters, which are arbitrarily registered in advance by the operator, that is, the laser output, the laser pulse frequency, the duty, the scanning speed, etc., are stored in the processing parameter memory 2 by the data input device 4. These processing parameters are managed by the identification number a designated by the operator.

Next, the movement parameter consisting of a series of coordinates and interpolation method created by the operator is given an identification number b by the operator for each block that constitutes the minimum movement command, that is, for each so-called CL data. It is stored in the management device 1. In this case, the movement parameter may be registered by using a digitizer, by using the drawing information on the CRT screen, or by key input as in the conventional automatic programming device described above. .

In addition, the operator inputs 1 of the machining parameter identification number a and the CL data-added identification number b by data input 4.
Register in correspondence with one-to-one. Then, this correspondence information is stored in the identification number storage device 3.

In this state, when the generation of the control program is started, the combination determination device 5 first reads the first CL data from the graphic information management device 1. Next, the combination determination device 5
Checks the machining parameter identification number a corresponding to the identification number b added to the CL data from the identification number storage device 3, reads the corresponding machining parameter information from the processing parameter storage device 2 and adds it to the CL data. And transmits it to the control program generator 6.

On the other hand, the control program generation device 1 generates a minimum control program based on the transmitted CL data and machining parameters and stores it in the control program storage unit 7. After that, the above-described processing is repeated until the CL data stored in the graphic information management device 1 is completed, and the control program is completed.

FIGS. 2A to 2C are flow charts showing the processing contents of the above-mentioned automatic programming device. That is, the processing parameter and the identification number a are registered in advance by the operator as shown in FIGS. Then, when the control program generation is started as shown in FIG. 7C, the CL data stored in advance is sequentially read, the identification number a corresponding to the identification number b added to this data is searched, and it is attached to this. Read the processing parameter to be used. Then, a control program including a movement command and a sequence command is generated and stored based on the corresponding CL data and the processing parameter.

As described above, in the automatic programming device according to the present embodiment, the movement command and the sequence command are independently registered, and these are combined, in other words, the program is not stored separately in the plurality of programs but is a component of the program. Since they are separately registered by (movement command or sequence command) and these are combined, the control program can be generated extremely efficiently.

That is, since it is possible to separate the move instruction and the sequence instruction, and each can be independently modified,
It is possible to efficiently generate a control program, easily modify the sequence program, and obtain an excellent effect that a sequence command can be accumulated as machining know-how regardless of a machining shape.

It should be noted that the present invention is not limited to the above-described embodiments, but can be carried out as follows.

In the above-mentioned embodiment, the identification numbers of the processing parameters may be further combined to form one comprehensive identification number.
For example, in the case of laser cutting, if a general identification number is added for each material and plate thickness, and several identification numbers of processing parameters are added, the operator can specify the material and plate name. It is possible to easily identify some of the processing parameters contained therein, and it is extremely easy to correct and manage them.

Also, by making it correspond to the CRT screen of the identification number added to the CL data, the display color at the time of drawing, the pen color type number, and the selection number, you can see the setting status of the processing parameters for the figure at a glance. It can be identified and the work is extremely easy. This allows the operator to select several machining parameters based on the material and plate thickness, and by changing the color of the graphic element when creating each CL data, that is, during drawing,
It is possible to specify processing parameters.

In addition, the present invention can be variously modified and implemented within the scope of the invention.
