(Background leading up to this disclosure)
Conventionally, as shown in Patent Literature 1, there has been disclosed a setting support device for determining the appropriateness of newly input new welding conditions. However, since the degree of adequacy of the welding conditions determined by this setting support device is determined based on the actual welding conditions used in the past, there is a problem that it is not known whether the quality of welding performed based on the new welding conditions satisfies the quality desired by the operator.

Therefore, in each of the following embodiments, examples of a welding machine power supply device, a welding condition generation method, and a welding condition generation support system that support the setting of welding conditions desired by a worker will be described.

Hereinafter, each embodiment specifically disclosing a power supply device for a welding machine, a welding condition output method, and a welding condition generation support system according to the present disclosure will be described in detail with reference to the drawings as appropriate. However, more detailed description than necessary may be omitted. For example, detailed descriptions of well-known matters and redundant descriptions of substantially the same configurations may be omitted. This is to avoid unnecessary verbosity in the following description and to facilitate understanding by those skilled in the art. It should be noted that the accompanying drawings and the following description are provided to allow those skilled in the art to fully understand the present disclosure and are not intended to limit the claimed subject matter.

Hereinafter, the object to be welded (for example, metal) is defined as a "workpiece", and the object to be welded produced (manufactured) by welding is defined as a "work". A "work" is not limited to a work produced by one welding, but may be a composite work produced by two or more weldings.

(Embodiment 1)
First, a welding output device PS1 according to Embodiment 1 will be described with reference to FIG. Welding output device PS1 is an example of a power supply device for a welding machine. FIG. 1 is a block diagram showing an internal configuration example of a welding output device PS1 according to Embodiment 1. As shown in FIG.

The welding output device PS1, which is an example of a power supply device for a welding machine, is a device that generates and sets welding conditions based on an operator's input operation, and outputs a control command for feeding the welding wire corresponding to the welding conditions and the welding output of the welding torch. The welding output device PS1 generates a welding condition input screen SC1 (see FIG. 2) capable of accepting an input operation regarding welding conditions by the operator, and outputs (displays) it on the display unit 13. FIG. Welding output device PS1 generates parameters of welding conditions set based on the operator's operation. The welding output device PS1 includes a motor circuit 10, a processor 11, a memory 12, a display section 13, an input section 14, and a welding output circuit 15.

Here, the parameters of the welding conditions are control information for controlling the welding torch in the welding process of welding the workpieces to manufacture the workpieces, and include at least control information regarding the welding power (welding current, welding voltage) output to the welding torch. The parameters of the welding conditions may include information other than the above-described control information related to the welding power of the welding torch. For example, the welding method, preflow gas time, wire feed speed, afterflow time, pulse presence/absence selection, pulse current, pulse frequency, pulse width, crater presence/absence selection, initial current, crater current, upslope time, downslope time, AC waveform, AC frequency, EN ratio, AC/DC ratio and AC/DC frequency, voltage data (unified voltage data) determined centrally corresponding to the welding current, and welding speed. It may include control information such as coefficients representing the relationship between corresponding plate thickness and welding current, workpiece weld joint geometry and welding speed.

The motor circuit 10 acquires a control command relating to welding wire feeding output from the processor 11 . Based on the obtained control command, the motor circuit 10 drives the motor to feed the welding wire by the feeding device T1.

The processor 11 as an example of the control unit is configured using, for example, a CPU (Central Processing Unit) or FPGA (Field Programmable Gate Array), and cooperates with the memory 12 to perform various processes and controls. Specifically, the processor 11 refers to the program held in the memory 12 and implements the function by executing the program.

The processor 11 acquires search conditions related to welding condition parameters output from the input unit 14, such as the material of the work piece, the wire diameter of the welding wire, the type of gas used for welding, the shape of the welded joint of the work piece, and identification information that can identify the work to be manufactured (e.g., production number, work identification number, work name, etc.). The processor 11 determines whether or not there is at least one welding condition corresponding to the acquired search condition among the plurality of welding conditions stored in the welding condition table TB of the memory 12 .

Here, the welding condition table TB stores parameters of welding conditions set in the past in association with the operator's evaluation information for welding executed based on these welding conditions. When at least part of the welding conditions are changed by operator operation, the welding condition table TB further stores the parameters of the welding conditions before the change, the parameters of the new welding conditions after the change, and the operator's evaluation information corresponding to the new welding conditions after the change in association with each other. That is, the welding condition table TB stores and manages parameters of new welding conditions (that is, change history information of welding conditions) and evaluation information of workers corresponding to the new welding conditions (that is, evaluation history information of workers corresponding to the welding conditions) in chronological correspondence, and stores and manages them for each welding condition.

When the processor 11 determines that there is a welding condition that matches the acquired search condition, it extracts at least one welding condition that matches the search condition and the evaluation information of the worker corresponding to this welding condition, and outputs and displays it on the display unit 13. If the extracted welding conditions are associated with the welding condition change history information or the operator's evaluation history information corresponding to the welding conditions, the processor 11 generates a welding condition input screen including the welding condition change history information and the operator's evaluation history information corresponding to the welding conditions, and outputs it to the display unit 13 for display.

On the other hand, if the processor 11 determines that there is no welding condition that satisfies the acquired search conditions, it generates a notification to the effect that there is no welding condition that satisfies the search conditions, and outputs it to the display unit 13 for display.

The processor 11 receives, via the input unit 14, an operation to change parameters of the welding conditions displayed on the display unit 13 and an input operation of the operator's evaluation information corresponding to the welding conditions. When the processor 11 receives an operation to change the parameters of the welding conditions, the processor 11 changes the parameters of the welding conditions based on the operator's operation. The processor 11 associates the parameters of the new welding conditions with the welding conditions before change and stores them in the welding condition table TB. When the processor 11 receives an input operation of the operator's evaluation information corresponding to the welding condition, the processor 11 associates the operator's evaluation information with the parameter of the welding condition specified by the operator and stores the operator's evaluation information in the welding condition table TB.

The memory 12, which is an example of a storage unit, has a RAM (Random Access Memory) as a work memory used, for example, when executing the processing of the processor 11, and a ROM (Read Only Memory) that stores a program that defines the processing of the processor 11. Data generated or acquired by the processor 11 is temporarily stored in the RAM. A program that defines the processing of the processor 11 is written in the ROM. The memory 12 also stores a welding condition table TB.

The display unit 13 may be configured using a display device such as an LCD (Liquid Crystal Display) or an organic EL (Electroluminescence). The display unit 13 outputs the welding condition input screen SC1 output from the processor 11 .

The input unit 14 is an interface that detects an operator's input operation and outputs it to the processor 11, and may be configured using, for example, buttons, switches, a jog dial, a mouse, a keyboard, and the like. Note that the input unit 14 may be implemented as a touch panel configured integrally with the display unit 13 .

The welding output circuit 15 is controlled by the processor 11 to perform welding output to the welding torch. The welding output circuit 15 performs welding output to the welding torch based on the control information regarding the welding power (welding current, welding voltage) included in the welding condition parameters output from the processor 11 .

Next, the welding condition input screen SC1 displayed on the display unit 13 will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of the welding condition input screen SC1 according to the first embodiment. Note that the welding condition input screen SC1 shown in FIG. 2 is merely an example, and the present invention is not limited to this. In addition, FIG. 2 illustrates a welding condition input screen SC1 capable of accepting an operator's operation regarding the size of a ball at the tip of a wire at the end of welding as an example of a parameter of welding conditions, but it goes without saying that the parameters of welding conditions that can be set on the welding condition input screen SC1 are not limited to this.

The welding condition input screen SC1 is generated by the processor 11, output to the display unit 13, and displayed. The welding condition input screen SC1 includes, for example, a welding performance setting area SC11 and a welding condition input area SC12.

The welding performance setting area SC11 is an area that includes descriptive information about welding condition parameters (in the example shown in FIG. 2, the welding conditions related to the size of the ball at the tip of the wire at the end of welding), and includes a welding condition input area SC12 that can accept operator operations for predetermined parameters.

The welding condition input area SC12 accepts the operator's operation regarding the size of the ball at the tip of the wire at the end of welding, based on the position of the slider C1 that can be moved in the horizontal direction of the drawing by the operator's operation. In the example shown in FIG. 2, the processor 11 generates and sets a welding condition parameter that decreases the size of the ball at the tip of the wire at the end of welding as the slider C1 is moved to the left side of the paper, and generates and sets a parameter of the welding condition that increases the size of the ball at the tip of the wire at the end of welding as the slider C1 is moved to the right side of the paper.

Next, a screen transition example of the welding condition input screen SC1 will be described with reference to FIGS. FIG. 3 is a diagram illustrating an example of screen transition of the welding condition input areas SC12A, SC12B, and SC12C according to the first embodiment. FIG. 4 is a diagram illustrating an example of screen transition of the welding condition input areas SC12D and SC12E according to the first embodiment.

In the welding condition input area SC12A, the processor 11 generates and sets the first welding condition parameter corresponding to the position of the slider C1. The operator performs welding under the first welding condition set corresponding to slider C1.

The welding condition input area SC12A accepts input of evaluation information "5" by operator operation. The evaluation information “5” referred to here is the operator's evaluation of the welding performed using the first welding condition parameter generated corresponding to the position of the slider C1.

The processor 11 associates and stores the position information of the slider C1, the evaluation information "5" input by the operator, and the time information when the parameter of the first welding condition for the same workpiece was changed (that is, the time information when the new welding condition was generated). The processor 11 generates a welding condition input area SC12B including the input history information SL11, generates a welding condition input screen SC1 including this welding condition input area SC12B, and outputs it to the display unit 13 for display.

The operator moves the slider C1 shown in the welding condition input area SC12B to the position of the slider C2 shown in the welding condition input area SC12C.

The processor 11 generates and sets parameters of the second welding condition corresponding to the position of the slider C2. In addition, the processor 11 generates history information SL12 including "▲ (triangular figure)" indicating the position of the slider C1 corresponding to the parameter of the first welding condition and evaluation information "5" of the first welding condition corresponding to the position of the slider C1. Processor 11 generates welding condition input area SC12C including history information SL12 and slider C2 after movement, and outputs it to display unit 13 for display.

As a result, the welding output device PS1 allows the operator to intuitively grasp the position of the slider C1 when the first welding condition is set (changed) and the evaluation result "5" of the welding condition, thereby supporting the setting of the new welding condition (that is, the second welding condition) for the first welding condition.

In the welding condition input area SC12C, the processor 11 generates and sets parameters of the second welding condition corresponding to the position of the slider C2. Processor 11 generates control information regarding welding power (welding current, welding voltage) based on the parameters of the second welding condition set corresponding to slider C2 and outputs the control information to welding output circuit 15 . The welding output circuit 15 outputs welding output based on the control information to the welding torch.

The welding condition input area SC12D accepts input of evaluation information "8" by operator operation. The evaluation information "8" referred to here is an evaluation of welding performed under the second welding conditions generated corresponding to the position of the slider C2.

The processor 11 associates and stores the position information of the slider C2, the evaluation information "8" input by the operator, and the time information when the welding conditions for the same workpiece were changed. The processor 11 generates a welding condition input area SC12D including the input history information SL21 and the first welding condition history information SL13, generates a welding condition input screen SC1 including this welding condition input area SC12D, and outputs it to the display unit 13 for display.

Here, the processor 11 generates a welding condition input area SC12D in which the history information SL21 of the second welding condition is highlighted rather than the history information SL13 of the first welding condition. For example, the processor 11 displays the first welding condition history information SL13 in a lighter color, a smaller character size, a thinner line type, or the like than the latest welding condition history information SL21, or displays the first welding condition history information SL13 in a different color from the second welding condition history information SL21.

The operator moves the slider C2 shown in the welding condition input area SC12D to the position of the slider C3 shown in the welding condition input area SC12E.

The processor 11 generates and sets a third welding condition (that is, a new welding condition) corresponding to the position of the slider C3. The processor 11 also generates history information SL13 of the first welding condition, history information SL22 of the second welding condition including "▴ (triangular figure)" indicating the position of the slider C2, and evaluation information "8" of the second welding condition corresponding to the position of the slider C2. The processor 11 generates a welding condition input area SC12E including the history information SL13, SL22 and the slider C3 after movement, and outputs it to the display unit 13 for display.

As a result, the welding output device PS1 allows the operator to intuitively grasp the position of the slider C1 when the first welding condition is set and the welding condition evaluation result "5", and the position of the slider C2 when the second welding condition is set and the welding condition evaluation result "8", respectively, thereby supporting the setting of a new welding condition (third welding condition) for a plurality of past welding conditions (that is, each of the first welding condition and the second welding condition).

As described above, the welding output apparatus PS1 according to Embodiment 1 includes an input unit 14 (an example of an acquisition unit) capable of acquiring operator evaluation information (an example of welding evaluation information) corresponding to a welding condition and a command to change the welding condition, a display unit 13 that displays the welding condition (an example of the welding condition before change), and the operator's evaluation information corresponding to the welding condition acquired by the input unit 14, and a change command that corresponds to the welding condition displayed on the display unit 13 (for example, according to the operator's operation). a processor 11 (an example of a control unit) that acquires a welding condition change operation based on the acquired change command, generates a new welding condition in which the welding condition is changed based on the acquired change command, and outputs a welding output based on the generated new welding condition.

As a result, the welding output apparatus PS1 according to Embodiment 1 displays the welding condition input screen SC1 including the welding conditions before the change and the evaluation results of the welding conditions before the change when the new welding conditions are set. Since the welding condition input screen SC1 can accept the operator's operation for setting the new welding conditions (that is, the operation for changing the welding conditions), it is possible to support the setting of the new welding conditions for the past welding conditions (that is, the welding conditions before the change) performed by the operator. Therefore, the operator can set new welding conditions while viewing the welding conditions before change and the evaluation results of the welding conditions before change.

Further, as described above, the welding output device PS1 according to Embodiment 1 further includes a memory 12 (an example of a storage unit) that associates and stores welding conditions and evaluation information corresponding to the welding conditions. The processor 11 associates the new welding conditions with the welding conditions and the evaluation information corresponding to the welding conditions and stores them in the memory 12 . Thereby, the welding output device PS1 according to Embodiment 1 can store the change history of the welding conditions.

Also, as described above, the memory 12 in the welding output device PS1 according to Embodiment 1 associates the new welding conditions with the welding conditions and the evaluation information corresponding to the welding conditions and stores them in chronological order. Thereby, the welding output apparatus PS1 according to Embodiment 1 can store the change history of the welding conditions and the evaluation information of the worker corresponding to the welding conditions.

Also, as described above, the processor 11 in the welding output device PS1 according to Embodiment 1 causes the display unit 13 to display a plurality of welding conditions and evaluation information corresponding to the plurality of welding conditions. As a result, the welding output device PS1 according to Embodiment 1 generates and displays a welding condition input screen SC1 that can compare a plurality of welding conditions set in the past with the evaluation information corresponding to the plurality of welding conditions.

Also, as described above, the processor 11 in the welding output device PS1 according to Embodiment 1 highlights the evaluation information corresponding to the latest welding condition among the plurality of welding conditions displayed on the display unit 13. As a result, the welding output device PS1 according to Embodiment 1 can distinguish between the evaluation information corresponding to the latest welding conditions and the evaluation information corresponding to other welding conditions, thereby enabling the operator to set new welding conditions.

Further, as described above, the processor 11 in the welding output device PS1 according to Embodiment 1 changes the display color of the evaluation information corresponding to the welding conditions displayed on the display unit 13 based on the welding conditions stored in the memory 12 and the evaluation information corresponding to the welding conditions in chronological order. As a result, the welding output device PS1 according to Embodiment 1 can visualize changes in the welding conditions and changes in the evaluation information corresponding to the welding conditions, and can assist the operator in setting new welding conditions.

(Modification of Embodiment 1)
In the first embodiment, the welding condition setting support method executed by the welding output device PS1 has been described. In the modification of Embodiment 1, an example of a welding condition setting support method executed by welding output device PS1A and input/output device P1 will be described. In addition, in the following description, the same reference numerals are used for the same components as those in the first embodiment, and the description thereof will be omitted.

FIG. 5 shows a system configuration example and an internal configuration example of a welding condition generation support system 100 according to a modification of the first embodiment. The system configuration example and the internal configuration example of the welding condition generation support system 100 according to the modification of the first embodiment shown in FIG. 1 are merely examples, and needless to say, the present invention is not limited thereto.

The welding condition generation support system 100 includes a welding output device PS1A and an input/output device P1, which is an example of an input device. The welding output apparatus PS1A according to the modification of the first embodiment manages parameters of welding conditions, change history information of parameters of welding conditions, evaluation history information of welding conditions, and outputs welding outputs based on parameters of welding conditions. Further, the input/output device P1 according to the modified example of the first embodiment realizes a function as a user interface, displays parameters of welding conditions, and accepts operator operations (that is, changes operations of parameters of welding conditions, and accepts operator's evaluation information input operations corresponding to welding conditions).

The welding output device PS1A includes a communication section 10A, a motor circuit 10B, a processor 11A, a memory 12A, and a welding output circuit 15A.

The communication unit 10A is connected to the input/output device P1 so that data can be transmitted and received, and outputs various data transmitted from the input/output device P1 to the processor 11A.

The motor circuit 10B acquires a control command regarding feeding of the welding wire output from the processor 11A. Based on the obtained control command, the motor circuit 10B drives the motor to feed the welding wire by the feeding device T1.

The processor 11A is configured using, for example, a CPU or FPGA, and cooperates with the memory 12A to perform various types of processing and control. Specifically, the processor 11A implements its functions by referring to the program held in the memory 12A and executing the program.

The processor 11A acquires search conditions related to welding condition parameters transmitted from the input/output device P1. The processor 11A determines whether or not there is at least one welding condition corresponding to the acquired search condition among the plurality of welding conditions stored in the welding condition table TBA of the memory 12A.

When the processor 11A determines that there is a welding condition that satisfies the acquired search conditions, it extracts at least one welding condition that satisfies the search condition and the evaluation information of the worker corresponding to this welding condition, outputs it to the communication unit 10A, and transmits it to the input/output device P1. On the other hand, if the processor 11A determines that there is no welding condition that matches the acquired search condition, it generates a notification that there is no welding condition that matches the search condition, outputs it to the communication unit 10A, and causes it to transmit to the input/output device P1.

The processor 11A accepts an operation to change the parameters of the welding conditions and an input operation of the operator's evaluation information corresponding to the welding conditions based on the control command transmitted from the input/output device P1. When the processor 11A receives an operation to change the parameters of the welding conditions, the processor 11A changes the parameters of the welding conditions based on the operator's operation. The processor 11A associates the parameters of the new welding conditions with the welding conditions before the change and stores them in the welding condition table TBA. When the processor 11A receives an input operation of the operator's evaluation information corresponding to the welding condition, the processor 11A associates the operator's evaluation information with the parameter of the welding condition specified by the operator and stores the operator's evaluation information in the welding condition table TBA.

The memory 12A has, for example, a RAM as a work memory that is used when executing the processing of the processor 11A, and a ROM that stores a program that defines the processing of the processor 11A. The RAM temporarily stores data generated or acquired by the processor 11A. A program that defines the processing of the processor 11A is written in the ROM. The memory 12A also stores a welding condition table TBA.

The welding output circuit 15A is controlled by the processor 11A to perform welding output to the welding torch. The welding output circuit 15A performs welding output to the welding torch based on the control information regarding the welding power (welding current, welding voltage) included in the welding condition parameters output from the processor 11A.

The input/output device P1 is implemented by, for example, a PC (Personal Computer), a notebook PC, a tablet terminal, a smartphone, etc., and is connected to the welding output device PS1A so that data can be transmitted and received.

The input/output device P1 includes a communication unit 20, a processor 21, a memory 22, a display unit 23, and an input unit 24.

The communication unit 20 is connected to the welding output device PS1A for wireless or wired communication, and transmits and receives data. The wireless communication here is communication via a wireless LAN (Local Area Network) such as Wi-Fi (registered trademark). Communication unit 20 acquires various data transmitted from welding output device PS1A and outputs the data to processor 21 .

The processor 21 is configured using, for example, a CPU or FPGA, and cooperates with the memory 22 to perform various types of processing and control. Specifically, the processor 21 refers to the program held in the memory 22 and implements the function by executing the program.

The processor 21 accepts input of search conditions based on the operator's operation via the input unit 24 . Processor 21 generates a control command requesting parameters of welding conditions corresponding to the input search condition, and transmits the control command to welding output device PS1A. Processor 21 outputs the parameters of the welding conditions transmitted from welding output device PS1A to display unit 23 for display. Here, if the extracted welding conditions are associated with the modification history information of the welding conditions or the evaluation history information of the worker corresponding to the welding conditions, the processor 21 generates a welding condition input screen including these information, and outputs and displays it on the display unit 23.

On the other hand, when the processor 21 determines that there is no welding condition that satisfies the acquired search conditions, it generates a notification to the effect that there is no welding condition that satisfies the search conditions, and outputs it to the display unit 23 for display.

The processor 21 receives, via the input unit 24, an operation to change parameters of the welding conditions displayed on the display unit 23 and an input operation of the operator's evaluation information corresponding to the welding conditions. The processor 21 converts an operation for changing parameters of the received welding conditions or an operation for inputting evaluation information of the operator corresponding to the welding conditions into an electric signal (control command), outputs it to the communication unit 20, and transmits it to the welding output device PS1A.

The memory 22 has, for example, a RAM as a work memory that is used when executing the processing of the processor 21, and a ROM that stores a program that defines the processing of the processor 21. Data generated or acquired by the processor 21 is temporarily stored in the RAM. A program that defines the processing of the processor 21 is written in the ROM.

The display unit 23 may be configured using a display device such as LCD or organic EL. The display unit 23 outputs the welding condition input screen SC1 (see FIG. 2) output from the processor 21. FIG.

The input unit 24 is an interface that detects the operator's input operation and outputs it to the processor 21, and may be configured using, for example, a mouse and a keyboard. Note that the input unit 24 may be implemented as a touch panel configured integrally with the display unit 23 .

As described above, in the welding condition generation support system 100 according to the modification of the first embodiment, the operator operates the input/output device P1 (an example of the input device) to input the evaluation information (an example of the welding evaluation information) corresponding to the welding conditions of the work produced by welding to the welding output device PS1A (an example of the computer) using the welding output device PS1A (an example of the welding machine power supply device) configured including one or more computers communicably connected to the input/output device P1. , the input/output device P1 displaying welding conditions and evaluation information corresponding to the welding conditions acquires new welding conditions based on the operator's operation, inputs them to the welding output device PS1A, and outputs welding output based on the input new welding conditions.

As a result, in the welding condition generation support system 100 according to the modification of the first embodiment, when the new welding conditions are set, the input unit 24 of the input/output device P1 on which the welding condition input screen SC1 including the welding conditions before the change and the evaluation results of the welding conditions before the change is displayed receives the input of the new welding conditions based on the operator's operation, and inputs the received new welding conditions to the welding output device PS1A, thereby outputting the welding output based on the input new welding conditions. Therefore, the operator can set new welding conditions while viewing the welding condition input screen SC1 including the welding conditions before change and the evaluation results of the welding conditions before change.

As described above, the welding condition generation support system 100 according to the modification of the first embodiment includes a welding output device PS1A (an example of a welding machine power supply device) that outputs welding conditions, and an input/output device P1 that can communicate with the welding output device PS1A and can acquire welding evaluation information corresponding to welding conditions and welding condition changing operations (for example, welding condition changing operations based on operator operations). Welding output device PS1A associates welding conditions with welding evaluation information corresponding to the welding conditions and transmits them to input/output device P1. The input/output device P1 displays welding conditions and evaluation information corresponding to the welding conditions, receives change operations for changing the displayed welding conditions, and transmits control commands corresponding to the change operations to the welding output device PS1A. Welding output device PS1A outputs a welding output based on the new welding conditions, which are the changed welding conditions, based on the control command.

As a result, the welding conditions for the welding conditions for the transformation of the embodiment 1 of the embodiment 1 are based on the input / output device P1 in the input / output device P1 where the welding condition input screen SC1, which includes the welding conditions before the change and the evaluation results of the welding conditions before the change, are based on the worker operation. By accepting the input of the new welding conditions, and inputting the new welding conditions accepted in the welding output device PS1a, the welding output based on the new welding condition entered by the welding output device PS1a can be output. Therefore, the operator can set new welding conditions while viewing the welding condition input screen SC1 including the welding conditions before change and the evaluation results of the welding conditions before change.
