Japanese Patent Application Publication No. 2007-30031

A laser oscillator cannot output laser light in the initial state when the power is just turned on. Therefore, it is necessary to execute a predetermined start-up process to switch the laser oscillator from its initial state to a ready state in which it can output a laser. However, the start-up process may differ depending on the model of the laser oscillator. Further, the shutdown process for returning the laser oscillator from the ready state to the initial state may also differ depending on the model of the laser oscillator.

Therefore, a PLC (programmable logic controller) or the like is introduced into the laser processing control device, and the user uses the PLC to check the model of the laser oscillator each time the user starts or ends using the laser oscillator using a ladder or the like. It was necessary to selectively execute switching programs such as start-up programs and fall-down programs corresponding to the above. Further, similar problems may also occur in the case of various processing equipment other than laser oscillators.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. However, the present disclosure is not limited to the following embodiments, and can be implemented with appropriate modifications within the scope of the spirit of the present disclosure.

[First embodiment]
First, a first embodiment will be described with reference to FIGS. 1 to 5. As shown in FIG. 1, a laser processing control device 70 controls a laser processing system 90. The laser processing system 90 includes a robot arm 91, a processing nozzle 92, and a laser oscillator 95. The arm 91 movably holds a processing nozzle 92. The laser oscillator 95 is connected to the processing nozzle 92 and inputs a laser beam to the processing nozzle 92 . The processing nozzle 92 performs laser processing by irradiating a workpiece (not shown) with a laser input from a laser oscillator 95. Specifically, the laser oscillator 95 of this embodiment is a model A laser oscillator 95. Note that model A may be read as "first model".

The laser oscillator 95 cannot output laser in the initial state when the power is only turned on. Hereinafter, the state of the laser oscillator 95 that cannot output a laser will be referred to as an "initial state", and the state of the laser oscillator 95 that can output a laser will be referred to as a "ready state". Specifically, for example, the initial state is a state where cooling water is not flowing (a state where the chiller does not start) and a power saving state (a state where the LD power supply is not energized), so the laser oscillator 95 is in a state where it cannot output a laser, and in a ready state, cooling water is flowing, the temperature inside the refrigerator is stable, the power saving state is canceled, and laser oscillation is occurring, so the laser oscillator 95 is able to output a laser. It is in a state of

Hereinafter, the period before starting the laser output from the laser oscillator 95 to the processing nozzle 92 will be referred to as "before the use of the laser oscillator 95", and the period after the laser output from the laser oscillator 95 to the processing nozzle 92 has ended will be referred to as "the laser oscillator 95". After using 95. Before using the laser oscillator 95, it is necessary to execute a predetermined "startup process" to switch the laser oscillator from an initial state to a ready state. After using the laser oscillator 95, it is necessary to execute a predetermined "shut down process" to return the laser oscillator 95 from the ready state to the initial state.

In this embodiment, the laser processing control device 70 is a robot control device, and is mainly composed of one computer and a laser processing control program loaded into the computer. However, instead of this, the laser processing control program may be mainly composed of a plurality of computers and a laser processing control program made up of respective programs read into the computers. A computer includes a CPU, ROM, RAM, nonvolatile memory, and the like. The laser processing control program causes the computer to function as the laser processing control device 70 in cooperation with the computer.

The laser processing control device 70 includes a program command section 23 and a control section 30. The program command unit 23 mainly includes a computer, its display, keyboard, mouse, and the like. The program command section 23 is configured to be capable of inputting a machining program P and the like through a user's operation. Specifically, the program command section 23 is configured to be able to input the machining program P in a predetermined programming language such as NC language, C language, C++, Python, or the like.

The control unit 30 is mainly composed of a computer's CPU, RAM, etc. The control unit 30 controls the laser processing system 90 by executing the processing program P input to the program command unit 23. Thereby, the control unit 30 causes the laser processing system 90 to perform laser processing.

As mentioned above, the laser oscillator 95 cannot output laser in the initial state where the power is only turned on. Therefore, the laser processing control device 70 further includes an automatic switching section 75 for switching the state of the laser oscillator 95 between the initial state and the ready state. The automatic switching section 75 includes a registration section 24 , a model selection section 25 , a storage section 40 , and a switching section 50 .

The registration unit 24 is mainly composed of a computer, its display, keyboard, mouse, etc. The registration unit 24 is configured to be able to register switching programs P1 and P2 for switching the state of the laser oscillator 95 for each model A, B, C, . . . of the laser oscillator 95 according to a user's operation. The switching programs P1 and P2 include a "startup program P1" for switching the state of the laser oscillator 95 from the initial state to the ready state, and a "falling program P1" for switching the state of the laser oscillator 95 from the ready state to the initial state. program P2''. By operating the registration unit 24, the user can input the model of the laser oscillator 95 and the corresponding switching programs P1 and P2. P1 and P2 can be registered.

Specifically, in this embodiment, the laser processing system 90 includes the laser oscillator 95 of model A, as described above. Therefore, in this embodiment, the user inputs at least the model A and the corresponding startup program P1a and shutdown program P2a by operating the registration unit 24. The registration section 24 is configured to be able to input the switching programs P1 and P2 in the aforementioned predetermined programming language, that is, in a programming language that can be used when inputting the machining program P to the program command section 23.

The storage unit 40 is mainly composed of a portion of the computer that includes nonvolatile memory and the like. The storage unit 40 stores the model of the laser oscillator 95 input by the user through the operation of the registration unit 24 and the corresponding switching programs P1 and P2. Further, the storage unit 40 stores a predetermined model and all or part of the corresponding switching programs P1 and P2 in advance when the laser processing control device 70 is new, that is, when it is shipped from a factory. You can leave it there. In other words, the storage unit 40 not only stores the desired model and the corresponding switching programs P1 and P2 by the user's operation of the registration unit 24, but also stores the desired model and the corresponding switching programs P1 and P2 by the operation of the worker at the factory or the like. The model and at least part of the corresponding switching programs P1 and P2 may be stored. In this case, before the switching programs P1 and P2 are registered by the user's operation of the registration unit 24, at least part of the switching programs P1 and P2 corresponding to the predetermined model of the laser oscillator 95 has already been stored in the storage unit 40. I remember. Therefore, the effort required by the user to register at least a portion of the switching programs P1 and P2 corresponding to the predetermined model can be reduced.

The model selection section 25 is mainly composed of a computer, its display, keyboard, mouse, etc. The model selection unit 25 is configured to be able to select the model of the laser oscillator 95 by a user's operation. Specifically, in this embodiment, the user selects model A by operating the model selection section 25.

The switching unit 50 is mainly composed of a portion of the computer including the CPU, RAM, etc. The switching unit 50 reads out and executes the switching programs P1 and P2 for the selected model from the storage unit 40 in accordance with the use of the laser oscillator 95 based on the execution of the processing program P. That is, in this embodiment, the switching programs P1 and P2 for model A are read and executed. Specifically, the switching unit 50 executes the start-up program P1a of the model A before starting laser processing, that is, before using the laser oscillator 95 of the model A. Then, after the laser processing is finished, that is, after the laser oscillator 95 of the model A is used, the switching unit 50 executes the shutdown program P2a of the model A.

Next, the startup process performed in this embodiment will be described with reference to FIGS. 2 and 3. If the laser processing control device 70 does not have the automatic switching section 75, it is necessary to introduce a PLC (programmable logic controller) into the laser processing control device 70, as in the comparative example shown in FIG. There is. Then, the user needs to use the PLC to selectively execute a start-up program corresponding to model A using a programming language such as ladder, each time before starting laser processing.

In contrast, in this embodiment, as described above, the automatic switching section 75 is provided, and the start-up program P1a of the model A is registered and stored in the storage section 40 by the user's operation of the registration section 24. ing. Then, model A is selected by the user's operation of the model selection section 25. Therefore, as shown in FIG. 3, before starting laser processing based on the processing program P, the switching section 50 automatically selects the model A from the storage section 40 in response to the startup request D1 from the control section 30. The start-up program P1a is read out and executed. As a result, startup processing for model A is automatically executed.

Specifically, in the start-up process for model A, first, the laser processing control device 70 transmits a laser request Da1 requesting permission for control by itself to the laser oscillator 95. Upon receiving this, the laser oscillator 95 permits control on the condition that predetermined requirements are met, and transmits a laser allocation signal Ca2 to the laser processing control device 70. Upon receiving this, the laser processing control device 70 transmits a laser ON request Da3 to the laser oscillator 95. Upon receiving this, the laser oscillator 95 changes itself from the initial state to a ready state and transmits a laser ON signal Ca4 to the laser oscillator 95. Upon receiving this, the laser processing control device 70 transmits an analog control ON request Da5 requesting permission for its own analog control to the laser oscillator 95. Upon receiving this, the laser oscillator 95 allows analog control on the condition that predetermined requirements are met, and transmits an analog control ON signal Ca6 to the laser processing control device 70, and also sends a laser preparation completion signal Ca7 to the laser processing controller 70. It is transmitted to the processing control device 70.

With the above steps, the start-up process of the laser oscillator 95 of model A is completed. Therefore, the user does not need to selectively execute a start-up program corresponding to model A every time before starting laser processing using a program language such as a ladder using a PLC.

After the start-up process is completed, the switching unit 50 transmits a start-up completion notification C1 to the control unit 30. Thereby, the control unit 30 starts using the laser oscillator 95 of model A and starts laser processing.

Next, the shutdown process performed in this embodiment will be described with reference to FIGS. 4 and 5. If the laser processing control device 70 does not have the automatic switching section 75, it is necessary to introduce a PLC into the laser processing control device 70, as in the case of the comparative example shown in FIG. Then, the user needs to use the PLC to selectively execute a program for falling down corresponding to model A every time the laser processing is completed using a programming language such as ladder.

In contrast, in this embodiment, as shown in FIG. 5, after the laser processing based on the processing program P is completed, the switching section 50 automatically switches the storage section The shutdown program P2a of model A is read out from 40 and executed. As a result, the shutdown process for model A is automatically executed.

Specifically, in the shutdown process for model A, the laser processing control device 70 first turns off the analog control ON request Da5. Based on this, the laser oscillator 95 turns off the laser preparation completion signal Ca7, disables analog control, and turns off the analog control ON signal Ca6. After that, the laser processing control device 70 turns off the laser ON request Da3. Based on this, the laser processing control device 70 turns off the laser ON signal Ca4. After that, the laser processing control device 70 turns off the laser request Da1. Based on this, the laser processing control device 70 turns off the laser allocation signal Ca2.

With the above steps, the shutdown process of the laser oscillator 95 of model A is completed. Therefore, the user does not need to selectively execute a program for falling down corresponding to model A every time laser processing is completed using a program language such as ladder using a PLC.

After completion of the shutdown process, the switching unit 50 transmits a shutdown completion notification C2 to the control unit 30. Thereby, the control unit 30 starts the next process based on the machining program P.

As described above, in this embodiment, the start-up program P1a of the model A is automatically executed before the laser processing based on the processing program P is performed, and after the laser processing based on the processing program P is performed, the startup program P1a of the model A is automatically executed. The lower program P2a is automatically executed.

In addition to before and after laser processing based on the processing program P, for example, in the following cases, the switching unit 50 reads and executes the switching programs P1 and P2 from the storage unit 40. That is, when laser processing is interrupted due to an emergency stop or when laser processing is interrupted due to a command other than a command based on the processing program, the switching unit 50 switches to the lowering mode corresponding to the selected model A. The program P2a is read from the storage unit 40 and executed. Then, when the laser processing is restarted after the laser processing is interrupted, the switching section 50 reads out the start-up program P1a corresponding to the selected model A from the storage section 40 and executes it.

On the other hand, even in any of the situations in which the start-up program P1a shown above should be executed, the switching unit 50 does not execute the start-up program P1a when the laser processing is disabled. The execution of the program P1 is skipped. The time when the laser processing is disabled includes, for example, when the user is in a teaching mode for teaching the laser processing system 90 an operation.

The configuration and effects of this embodiment are summarized below.

The registration unit 24 is configured to be able to register switching programs P1 and P2 for switching the state of the laser oscillator 95 by user operation, and the switching unit 50 selects the registered switching programs P1 and P2 for switching the state of the laser oscillator 95 according to the use of the laser oscillator 95. The programs P1 and P2 are read from the storage unit 40 and executed. Therefore, there is no need to prepare a PLC for switching the state of the laser oscillator 95.

Specifically, before the laser oscillator 95 of model A is used, the switching unit 50 reads out the start-up program P1a corresponding to model A from the storage unit 40 and executes it. Therefore, the user does not need to selectively execute a start-up program corresponding to model A each time before using the laser oscillator 95 using a program language such as ladder using a PLC.

Furthermore, after the laser oscillator 95 is used, the switching unit 50 reads out the shutdown program P2a corresponding to model A from the storage unit 40 and executes it. Therefore, the user does not need to selectively execute a program for falling down corresponding to model A every time the laser oscillator 95 is used, using a program language such as ladder using a PLC.

The registration unit 24 is configured to be able to register switching programs P1, P2 for each model A, B, C, . . . The switching programs P1 and P2 corresponding to the selected model are read out from the storage unit 40 and executed. Therefore, it is possible to cope with the case where a plurality of models A, B, C, etc. of the laser oscillator 95 to be used can be considered.

The switching unit 50 reads the switching programs P1 and P2 from the storage unit 40 and executes them in accordance with the use of the laser oscillator 95 based on the execution of the processing program P. Therefore, the start-up program P1 and the fall-down program P2 can be executed efficiently and at appropriate timing in synchronization with the machining program P.

The registration unit 24 is configured to be able to input the switching programs P1 and P2 using a programming language that allows the machining program P to be input to the program command unit 23. Therefore, even if the user cannot use a PLC programming language such as ladder, the user can cope with the situation.

The switching unit 50 reads the stop program P2 from the storage unit 40 and executes it when the laser processing is interrupted. Therefore, when laser processing is interrupted, the laser oscillator 95 can be turned off quickly.

The switching unit 50 reads the start-up program P1 from the storage unit 40 and executes it when restarting the laser processing after the interruption of the laser processing. Therefore, when laser processing is restarted, the laser oscillator 95 can be started up quickly.

The switching unit 50 skips execution of the start-up program P1 when the laser processing is disabled, in which an operation to disable the laser processing is performed. Therefore, the laser processing system 90 cannot irradiate the laser even if it makes a mistake, thereby ensuring greater safety.

Specifically, the time when the laser processing is disabled includes the time when the teaching mode in which the user teaches the laser processing system 90 an operation is selected. Therefore, safety in the teaching mode can be further ensured.

In this embodiment, the computer functions as the program command section 23 and the control section 30, as well as the automatic switching section 75, by cooperation between the computer and the laser processing control program. That is, the computer is made to function as the laser processing control device 70 of this embodiment. Therefore, this embodiment can be implemented using a computer.

[Second embodiment]
Next, a second embodiment will be described with reference to FIGS. 6 to 10. The following embodiments will be described based on the first embodiment, focusing on points different from the first embodiment, and descriptions of the same or similar points as the first embodiment will be omitted as appropriate.

As shown in FIG. 6, in this embodiment, the laser processing system 90 includes a model B laser oscillator 95 instead of the model A laser oscillator 95 shown in the first embodiment. Therefore, in this embodiment, the user selects model B by operating the model selection section 25. Note that model B may be read as "second model".

Next, the startup process performed in this embodiment will be described with reference to FIGS. 7 and 8. If the laser processing control device 70 does not have the automatic switching section 75, it is necessary to introduce a PLC as in the case of the comparative example shown in FIG. Then, the user needs to use the PLC to selectively execute a start-up program corresponding to model B using a programming language such as a ladder program each time before starting laser processing.

In contrast, in this embodiment, as shown in FIG. 8, before starting laser processing based on the processing program P, the switching unit 50 automatically switches the memory A start-up program P1b for model B is read out from the unit 40 and executed. As a result, startup processing for model B is automatically executed.

Specifically, in the start-up process for model B, first, the laser oscillator 95 transmits a power-on signal Cb1 indicating that the power is on to the laser processing control device 70. Upon receiving this, the laser processing control device 70 transmits a standby request Db2 to the laser oscillator 95. Upon receiving this, the laser oscillator 95 changes itself from the initial state to a ready state and transmits a laser ready OK signal Cb3 and a standby OK signal Cb4 to the laser processing control device 70. Upon receiving this, the laser processing control device 70 transmits an analog control request Db5 requesting permission for control by itself to the laser oscillator 95. Upon receiving this, the laser oscillator 95 permits control on the condition that predetermined requirements are met, and transmits the laser ON signal Cb6 to the laser processing control device 70.

With the above steps, the start-up process of the laser oscillator 95 of model B is completed. Therefore, the user does not need to selectively execute the start-up program corresponding to model B every time before starting laser processing using a program language such as a ladder using a PLC.

Next, the shutdown process performed in this embodiment will be described with reference to FIGS. 9 and 10. If the laser processing control device 70 does not have the automatic switching section 75, it is necessary to introduce a PLC as in the case of the comparative example shown in FIG. Then, the user needs to use the PLC to selectively execute the fall program corresponding to model B using a program language such as a ladder program every time the laser processing is completed.

In contrast, in this embodiment, as shown in FIG. 10, after the laser processing based on the processing program P is completed, the switching section 50 automatically switches the storage section to The shutdown program P2b of model B is read out from 40 and executed. As a result, the shutdown process for model B is automatically executed.

Specifically, in the shutdown process for model B, the laser processing control device 70 first turns off the analog control request Db5. Based on this, the laser oscillator 95 turns off the laser ON signal Cb6. After that, the laser processing control device 70 turns off the standby request Db2. Based on this, the laser oscillator 95 sequentially turns off the standby OK signal Cb4, the laser ready OK signal Cb3, and the power-on signal Cb1. In this way, in this embodiment, a different fall process from that in the first embodiment is performed.

With the above steps, the shutdown process of the laser oscillator 95 of model B is completed. Therefore, the user does not need to selectively execute a program for falling down corresponding to model B every time laser processing is completed using a program language such as a ladder using a PLC.

As described above, according to this embodiment, even when the laser oscillator 95 is model B, the same effects as in the first embodiment can be obtained.

[Third embodiment]
Next, a third embodiment will be described with reference to FIG. 11. In this embodiment, the laser processing system 90 includes, in addition to the laser oscillator 95 of the model A shown in the first embodiment, the laser oscillator 95 of the model B shown in the second embodiment. The processing nozzle 92 is configured to be able to selectively input and irradiate either the laser from the laser oscillator 95 of the model A or the laser from the laser oscillator 95 of the machine B. In the figure, two

laser oscillators

95, 95 are connected to one processing nozzle 92, but

separate processing nozzles

92, 92 may be provided for each

laser oscillator

95, 95.

In other words, the laser processing control device 70 of this embodiment uses the laser oscillator 95 of model A and the laser oscillator 95 of model B depending on the purpose and the like. For this reason, the model selection section 25 is configured to be able to select a plurality of models as the model of the laser oscillator 95 to be used. Specifically, in this embodiment, the user selects model A as one model of the laser oscillator 95 to be used, and selects model B as the other model of the laser oscillator 95 to use, by operating the model selection unit 25. select.

In this case, before using the laser oscillator 95 of the model A based on the execution of the machining program P, the switching unit 50 reads out the start-up program P1a of the model A from the storage unit 40 and executes the start-up program P1a of the laser oscillator of the model A. 95, the shutdown program P2a for model A is read out from the storage unit 40 and executed. Then, before using the laser oscillator 95 of the model B based on the execution of the machining program P, the switching unit 50 reads the start-up program P1b of the model B from the storage unit 40 and executes the start-up program P1b of the laser oscillator 95 of the model B. After using the program, the shutdown program P2b for model B is read out from the storage unit 40 and executed.

As described above, according to the present embodiment, the switching unit 50 reads the switching programs P1a and P2a corresponding to the model A from the storage unit 40 in accordance with the use of the laser oscillator 95 of the model A based on the execution of the processing program P. Read and execute. Then, the switching unit 50 reads switching programs P1b and P2b corresponding to the model B from the storage unit 40 and executes them in accordance with the use of the laser oscillator 95 of the model B based on the execution of the machining program P. Therefore, it is possible to cope with the case where it is desired to switch and use a plurality of laser oscillators 95.

[Fourth embodiment]
Next, a fourth embodiment will be described with reference to FIGS. 12 and 13. In this embodiment, instead of the laser processing system, there is provided a coating system that paints the workpiece, and instead of the laser processing control device 70, there is provided a coating control device 70d that controls the coating system.

The coating system includes a coating device 95d of model α. Therefore, in this embodiment, the user selects the model α by operating the model selection section.

Next, the startup process performed in this embodiment will be described with reference to FIG. 12. Before starting coating based on the machining program P, the switching unit 50 automatically reads out and executes the startup program P1d for the model α from the storage unit in response to a startup request D1 from the control unit 30. As a result, startup processing for model α is automatically executed.

Specifically, in the start-up process for model α, first, the coating control device 70d sends a valve control ON request Dd1 to the coating device 95d requesting permission to control the valve of the coating device 95d by itself. Upon receiving this, the coating device 95d permits valve control on the condition that predetermined requirements are met, and transmits a valve control ON signal Cd2 to the coating control device 70d. Upon receiving this, the coating control device 70d transmits a sealing material filling request Dd3 to the coating device 95d. Upon receiving this, the coating device 95d fills the sealing material and transmits a sealing material filling completion signal Cd4 to the coating control device 70d. Upon receiving this, the coating control device 70d transmits a preparation pressure request Dd5 to the coating device 95d. Upon receiving this, the coating device 95d increases the internal pressure and transmits a preparation pressure completion signal Cd6 to the coating control device 70d.　

With the above steps, the start-up process of the coating device 95d of model α is completed. Therefore, the user does not need to selectively execute the start-up program corresponding to the model α every time before starting coating using a program language such as a ladder using a PLC. After the start-up process is completed, the switching unit 50 transmits a start-up completion notification C1 to the control unit 30.

Next, the shutdown process performed in this embodiment will be described with reference to FIG. 13. After the coating based on the machining program P is completed, the switching unit 50 automatically reads out the shutdown program P2d of the model α from the storage unit and executes it in response to the shutdown request D2 from the control unit 30. As a result, the shutdown process for model α is automatically executed.

Specifically, in the shutdown process for model α, first, the coating control device 70d turns off the preparation pressure request Dd5. Based on this, the coating device 95d lowers the internal pressure and turns off the preparation pressure completion signal Cd6. Thereafter, the coating control device 70d turns off the valve control ON request Dd1. Based on this, the coating device 95d cancels permission for valve control and turns off the valve control ON signal Cd2.

Through the above steps, the process of shutting down the coating device 95d of model α is completed. Therefore, the user does not have to use a PLC to selectively execute a program for falling down corresponding to the model α every time coating is completed using a programming language such as ladder. After completion of the shutdown process, the switching unit 50 transmits a shutdown completion notification C2 to the control unit 30.

As described above, according to this embodiment, even when the processing system is a coating system and the processing equipment is the coating device 95d, the same effects as in the first embodiment can be obtained.

[Other embodiments]
The embodiment shown above can be modified as follows, for example. By operating the registration unit 24, only one of the startup program P1 and the shutdown program P2 is registered, and the processing corresponding to the other is performed by the PLC as in the case of the comparative example. It's okay.

Instead of selecting the model of the laser oscillator 95 by the user's operation of the model selection unit 25, the switching unit 50 automatically recognizes the model of the laser oscillator 95 connected to the processing nozzle 92 from the connection status etc. The switching programs P1 and P2 corresponding to the recognized model may be executed. According to this configuration, even the effort required by the user to select the model of the laser oscillator 95 by operating the model selection section 25 can be reduced.

The processing system is a laser processing system in the first to third embodiments, and a coating system in the fourth embodiment, but may be a system that performs or includes other processing. Other processing includes processing other than laser processing, such as cutting, pressing, tensioning, heating, and pressurization, such as removing a part of the workpiece, cutting it, breaking it, deforming it, or altering its quality. Examples include processing that adds additives to the workpiece, and processing other than coating that adds additives to the workpiece.
