For example, welding control unit 15 is configured with a CPU (arithmetic processing unit) and a memory storing a program, information, and the like for operating the CPU.
[ operation section ]
As shown in fig. 1, 2, and 3, the operation unit 11 includes an operation panel 20, a plurality of touch sensors 30, and a light emitting unit 40.
The operation panel 20 is formed in a sheet shape. In this example, the operation panel 20 is provided with a plurality of operation keys 50, one or more (one in this example) slide wheels 60, a plurality of display portions 70, and a display window 80.
The plurality of touch sensors 30 are provided on the back surface side of the operation panel 20 and at predetermined positions, respectively. Each of the plurality of touch sensors 30 detects that the operation panel 20 is touched at a position where the touch sensor 30 is arranged. The touch sensor 30 is formed of, for example, a capacitance type touch sensor.
The light emitting unit 40 selectively illuminates the plurality of operation keys 50, the slide wheel 60, and the plurality of display units 70 provided on the operation panel 20 by selectively irradiating light to the plurality of operation keys 50, the slide wheel 60, and the plurality of display units 70. For example, the light emitting unit 40 is composed of a plurality of light emitting elements such as light emitting diodes.
[ operating keys ]
The plurality of operation keys 50 are operated (specifically, touched) by the operator. In this example, symbols (patterns, characters, etc.) are assigned to each of the plurality of operation keys 50, and operation keys 50 are provided on operation panel 20 by forming a light-transmitting portion (portion through which light passes) having a shape corresponding to the symbol of operation key 50 on operation panel 20.
In this example, the plurality of operation keys 50 can be switched between the on state and the off state. Specifically, the operation key 50 is turned on by irradiating the light from the light emitting unit 40 to the light transmitting portion (light transmitting portion having a shape corresponding to the symbol of the operation key 50) constituting the operation key 50, and the operation key 50 is turned off by stopping the irradiation of the light to the light transmitting portion constituting the operation key 50. Here, the lighting state includes a continuous lighting state and an intermittent lighting state (i.e., a blinking state).
[ kind of operation key ]
In this example, the plurality of operation keys 50 include a sequence selection key 51, a current-voltage switching key 52, a home key 53, a shift key 54, a menu key 55, and the like.
An operation for selecting a welding sequence is applied to the sequence selection key 51. Specifically, by touching the sequence selection key 51, a process for selecting a welding sequence (sequence selection process) is performed.
The current/voltage switching key 52 is operated to switch between a voltage value and a current value in a partial setting process described later. Specifically, the voltage value and the current value are switched in the partial setting processing described later by touching the current/voltage switching key 52.
The home key 53 is operated to display a home screen (not described) on the display window 80. An operation for performing the switching operation is applied to the switching key 54.

[ Key touch sensor ]
The plurality of touch sensors 30 described above include a plurality of key touch sensors 31 corresponding to the plurality of operation keys 50, respectively. The plurality of key touch sensors 31 detect touches of the plurality of operation keys 50, respectively. In this example, the plurality of key touch sensors 31 are provided on the back surfaces of the plurality of operation keys 50, respectively. Then, the detection results (detection signals) detected by the plurality of key touch sensors 31 are sent to the operation control section 12. Thus, the operation control section 12 can detect touches of the plurality of operation keys 50 based on the detection results detected by the plurality of key touch sensors 31, respectively.
[ sliding wheels ]
The sliding wheel 60 is manipulated by an operator (specifically, a manipulation of tracing the sliding wheel 60). In this example, the pulley 60 is formed in a ring shape (in this example, an annular shape) in a plan view. Specifically, slide wheel 60 is provided on operation panel 20 by forming a light-transmitting portion having a shape (in this example, an annular shape) corresponding to the outer shape of slide wheel 60 on operation panel 20.
In this example, the surface height of the outer peripheral edge of the pulley 60 is higher than the surface height of a portion (hereinafter referred to as "inner peripheral portion") of the pulley 60 that is closer to the center of the pulley 60 than the outer peripheral edge. Specifically, in this example, the outer peripheral edge of the pulley 60 is formed by an annular convex portion, so that the surface height of the outer peripheral edge of the pulley 60 is higher than the surface height of the inner peripheral portion of the pulley 60. The inner circumferential portion of the pulley 60 may be formed by an annular concave portion, so that the surface height of the outer circumferential edge portion of the pulley 60 is higher than the surface height of the inner circumferential portion of the pulley 60.
In this example, the slide wheel 60 can be switched between the lit state and the extinguished state. Specifically, the slide wheel 60 is turned on by irradiating an annular translucent portion constituting the outer peripheral edge portion of the slide wheel 60 with light from the light emitting portion 40, and the slide wheel 60 is turned off by stopping the irradiation of the annular translucent portion with light.
[ sliding wheel touch sensor ]
The plurality of touch sensors 30 include a plurality of (eight in the example of fig. 3) sliding wheel touch sensors 32 corresponding to the sliding wheels 60. The plurality of sliding wheel touch sensors 32 detect an operation applied to the sliding wheel 60. In this example, the plurality of slide wheel touch sensors 32 are arranged in an annular shape on the back surface side of the slide wheel 60. Then, the detection results (detection signals) detected by the plurality of sliding wheel touch sensors 32 are sent to the operation control section 12. Thus, the operation control unit 12 can detect the operation applied to the slide wheel 60 based on the detection results detected by the plurality of slide wheel touch sensors 32.

< first numerical value display section >
An arbitrary numerical value of a predetermined number (three bits in this example) is displayed on the first numerical value display portion 72 a. In this example, the first numerical value display portion 72a is provided on the operation panel 20 by forming a plurality of light-transmitting portions corresponding to a plurality of stages for expressing an arbitrary three-digit numerical value on the operation panel 20. Then, the light from the light emitting portion 40 is selectively irradiated to the plurality of light transmitting portions (segments) constituting the first numerical value display portion 72a, whereby an arbitrary three-digit numerical value is displayed on the first numerical value display portion 72 a.
< first additional information display section >
The first additional information display unit 73a selectively displays a plurality of pieces of first additional information (in this example, five units of "m/min.", "mm", "%", "a", and "Hz") related to the numerical value displayed on the first numerical value display unit 72 a. In this example, the first additional information display unit 73a is provided on the operation panel 20 by forming a plurality of light-transmitting portions having shapes corresponding to symbols (symbols representing units, symbols, and the like) representing a plurality of pieces of first additional information on the operation panel 20.

The second additional information display unit 73b has the same configuration as the first additional information display unit 73 a.
< display part of sequence-related information >
The welding sequence information display unit 74 displays information (for example, whether or not there is a crater weld in the welding sequence) on the welding sequence corresponding to the sequence waveform displayed on the waveform display unit 71. In this example, the sequence related information display unit 74 is provided on the operation panel 20 by forming a light-transmitting portion having a shape corresponding to a symbol indicating information on the welding sequence on the operation panel 20. The light from the light emitting unit 40 is selectively emitted to the light transmitting portion constituting the sequence related information display unit 74, whereby information is selectively displayed on the sequence related information display unit 74.
< wave touch sensor >
The plurality of touch sensors 30 described above include a plurality of waveform touch sensors 33 each corresponding to a part of the serial waveform displayed on the waveform display unit 71. Each of the plurality of waveform touch sensors 33 detects that a part of the serial waveform displayed on the waveform display unit 71 (a part of the serial waveform corresponding to the waveform touch sensor 33) is touched. In this example, each of the plurality of waveform touch sensors 33 is disposed on the back side of a part of the serial waveform displayed on the waveform display section 71. Then, the detection results (detection signals) detected by the plurality of waveform touch sensors 33 are sent to the operation control section 12. Thus, the operation control unit 12 can detect that a part of the serial waveform displayed on the waveform display unit 71 is touched based on the detection results detected by the plurality of waveform touch sensors 33.
As shown in fig. 3, in this example, eight waveform touch sensors (first to eighth waveform touch sensors 33a to 33h) are provided.

< display Window >
The display window 80 displays various images such as an image indicating welding conditions, a home screen, and a menu screen. For example, the display window 80 is constituted by a liquid crystal display panel and a drive circuit that drives the liquid crystal display panel.
[ operation of the operation control section ]
The operation control section 12 controls the operation section 11 so that the start-up processing is performed at the start-up of the welder 10. The operation control unit 12 controls the operation unit 11 so that various processes such as a sequence selection process (a process of selecting a welding sequence) are performed in the welder 10 after the start. In this example, the operation control unit 12 controls the operation unit 11 (specifically, the light emitting unit 40) such that the operation key 50 whose operation is valid among the plurality of operation keys 50 is turned on, and the operation key 50 whose operation is invalid is turned off.
< Start-Up treatment >
In the startup process, the operation control unit 12 controls the operation unit 11 so that the operation unit 11 is in a predetermined startup initial state.
As shown in fig. 4, in the initial start-up state, an image indicating a predetermined welding condition (for example, a standard welding condition stored in the storage unit 13) is displayed on the display window 80. Further, the operation keys 50 (the operation keys 50 shaded in fig. 4) among the operation keys 50 that are effective in the operation are turned on, and the slider 60 is turned on. Further, a predetermined serial waveform (for example, a serial waveform corresponding to a welding sequence corresponding to a standard welding condition) is displayed on the waveform display portion 71, a predetermined current value (for example, a current value corresponding to a standard welding condition) is displayed on the first numerical value display portion 72a and the first additional information display portion 73a, and a predetermined voltage value (for example, a voltage value corresponding to a standard welding condition) is displayed on the second numerical value display portion 72b and the second additional information display portion 73 b. In fig. 4, the black portion is a portion in a lighting state. The same applies to fig. 5 and 6.
< sequence selection treatment >
Further, the operation control section 12 controls the operation section 11 so that when the sequence selection key 51 is touched, the sequence selection process is started in the operation section 11. Then, the operation control section 12 controls the operation section 11 so that the sequence waveform displayed on the waveform display section 71 changes in accordance with the touch of the sequence selection key 51 when the sequence selection key 51 is touched in the sequence selection process.
As shown in fig. 5, when the sequence selection key 51 is touched, the states of the waveform display section 71, the sequence related information display section 74, and the display window 80 are set to any one of the first state S11, the second state S12, and the third state S13. Thereafter, each time the sequence selection key 51 is touched, the states of the waveform display section 71, the sequence related information display section 74, and the display window 80 sequentially transition to the first state S11, the second state S12, and the third state S13. When the state of the waveform display section 71, the sequence information display section 74, and the display window 80 is set to any one of the first state S11, the second state S12, and the third state S13, if the subsequent select key 51 is touched at the change-over key 54, the state of the waveform display section 71, the sequence information display section 74, and the display window 80 transitions to the fourth state S14. When the state of the waveform display unit 71, the sequence related information display unit 74, and the display window 80 is set to the fourth state S14, the state of the waveform display unit 71, the sequence related information display unit 74, and the display window 80 is changed to the original state (any one of the first state S11, the second state S12, and the third state S13) when the sequence selection key 51 is touched.
In the first state S11, a sequence waveform corresponding to a welding sequence without crater welding is displayed on the waveform display portion 71. Specifically, the first segment 71a, the second segment 71b, the fourth segment 71d, the fifth segment 71e, the seventh segment 71g, the eighth segment 71h, and the tenth segment 71j are turned on, thereby displaying a sequence waveform corresponding to a welding sequence without crater welding. Further, an image in which a character "no crater" is described in a column of the control method (that is, an image indicating that the selected welding sequence is a welding sequence without crater welding) is displayed on the display window 80.
In the second state S12, a sequence waveform corresponding to the welding sequence with crater welding is displayed on the waveform display portion 71. Specifically, the first segment 71a, the second segment 71b, the fourth segment 71d, the fifth segment 71e, the seventh segment 71g, the ninth segment 71i, and the tenth segment 71j are turned on, thereby displaying a sequence waveform corresponding to a welding sequence in which crater welding is performed. Further, an image in which a character "crater" is described in a column of the control method (that is, an image showing that the selected welding sequence is a crater welding sequence) is displayed on the display window 80. In addition, a mark indicating that the sequence waveform displayed on the waveform display section 71 is a sequence waveform corresponding to a welding sequence with crater welding is displayed on the sequence related information display section 74.
In the third state S13, a sequence waveform corresponding to the welding sequence in which the initial crater welding is present is displayed on the waveform display portion 71. Specifically, the first segment 71a, the third segment 71c, the fourth segment 71d, the fifth segment 71e, the seventh segment 71g, the ninth segment 71i, and the tenth segment 71j are turned on, thereby displaying a sequence waveform corresponding to a welding sequence in which initial crater welding is performed. In addition, an image in which a character "initial crater" is described in a column of the control method (that is, an image indicating that the selected welding sequence is a welding sequence in which initial crater welding is performed) is displayed on the display window 80. In addition, a mark indicating that the sequence waveform displayed on the waveform display section 71 is a sequence waveform corresponding to a welding sequence with crater welding is displayed on the sequence related information display section 74.
In the fourth state S14, a sequence waveform corresponding to a welding sequence without crater welding is displayed on the waveform display portion 71. Specifically, the first segment 71a, the second segment 71b, the fourth segment 71d, the fifth segment 71e, the seventh segment 71g, the eighth segment 71h, and the tenth segment 71j are turned on, thereby displaying a sequence waveform corresponding to a welding sequence without crater welding. In addition, an image in which characters "arc spot" are described in a column of the control method is displayed on the display window 80.
< partial setting processing >
Further, when a part of the sequence waveform displayed on the waveform display unit 71 is touched in the sequence selection process, the operation control unit 12 controls the operation unit 11 so as to start a part setting process (setting related to a part of the welding sequence) for a part of the welding sequence (one process step) corresponding to the touched part of the sequence waveform. In the partial setting process, a current value or a voltage value relating to a part of the welding sequence is set, and the current value or the voltage value is displayed on the numerical value display portion (the first numerical value display portion 72a or the second numerical value display portion 72 b).
For example, as shown in fig. 6, when a segment representing the fourth section of the serial waveform displayed on the waveform display unit 71 (the fifth segment 71e in the example of fig. 6) is touched, the touched segment blinks, and the fourth section of the serial waveform is subjected to the partial setting process. In the partial setting processing for the fourth section of the sequence waveform, the current value is set. Here, when the current-voltage switching key 52 is touched, the set object is switched from the current value to the voltage value, and when the current-voltage switching key 52 is touched again, the set object is switched from the voltage value to the current value. When the current value in the fourth section of the sequence waveform is to be set, the numerical value (i.e., the current value) displayed on the first numerical value display portion 72a changes in accordance with the operation applied to the pulley 60. On the other hand, when the voltage value in the fourth section of the serial waveform is to be set, the numerical value (i.e., the voltage value) displayed on the second numerical value display portion 72b changes in accordance with the operation applied to the sliding wheel 60. When a segment representing the fourth section of the serial waveform displayed on the waveform display unit 71 (the fifth segment 71e in the example of fig. 6) is touched again, the current value (or the voltage value) in the fourth section of the serial waveform is set (identified) as the current value displayed on the first numerical value display unit 72a (or the voltage value displayed on the second numerical value display unit 72 b). In the partial setting processing, the length of the processing time such as the preflow time, the pulse frequency, and the like may be set in addition to the current value and the voltage value.
[ Effect produced by the embodiment ]
As described above, by displaying the sequence waveform (the outline shape of the welding waveform) corresponding to the welding sequence selected by the operation of the sequence selection key 51 on the waveform display portion 71, the operator can visually confirm the state of the welding sequence set. This can facilitate the operation of the welding machine 10 by the operator.
Further, by changing the sequence waveform displayed on the waveform display unit 71 in accordance with the touch of the sequence selection key 51, the operator can sequentially visually confirm the plurality of sequence waveforms one by one and select a desired sequence waveform (welding sequence) from the plurality of sequence waveforms. This can facilitate the operation of the welding machine 10 by the operator.
In this example, when a part of the sequence waveform displayed on the waveform display unit 71 is touched, a process (setting of a part of the welding sequence, specifically, setting of a current value or a voltage value) is set to a part of the start portion of the welding sequence corresponding to the touched part of the sequence waveform. Therefore, the operator can easily select a portion (a portion of the sequence waveform) desired to be subjected to the portion setting process from the sequence waveforms displayed on the waveform display unit 71. This can facilitate the operation of the welding machine 10 by the operator.
Further, by controlling the operation unit 11 so that the operation key 50 whose operation is valid among the plurality of operation keys 50 is turned on and the operation key 50 whose operation is invalid is turned off, the operator can easily find the operation key 50 whose operation is valid among the plurality of operation keys 50. This can facilitate the operation of the welding machine 10 by the operator.
Further, by providing a plurality of operation keys 50 and a plurality of display portions 70 on the operation panel 20 formed in a sheet shape, the operation surface of the operation portion 11 can be made flat. This can facilitate cleaning of the operation unit 11.
Further, since the surface height of the outer peripheral edge portion of the pulley 60 is made higher than the surface height of the inner peripheral portion of the pulley 60 (the portion of the pulley 60 on the center side of the outer peripheral edge portion of the pulley 60), the operator can check the position of the pulley 60 by the step of the outer peripheral edge portion of the pulley 60, and thus can operate the pulley 60 while viewing the information displayed on the operation portion 11. This can facilitate the operation of the welding machine 10 by the operator.
(modification of embodiment)
Note that the plurality of operation keys 50 may be capable of switching the lighting mode in the lighting state. Further, the operation control unit 12 may control the operation unit 11 so that the operation key 50 recommended to be operated next among the plurality of operation keys 50 is turned on in a manner different from the operation key 50 not recommended to be operated next.
For example, the plurality of operation keys 50 may be capable of switching the lighting color between a plurality of colors. Specifically, the light emitting unit 40 may be configured to selectively emit light of a plurality of colors. Further, the operation control unit 12 may control the operation unit 11 so that the lighting color of the operation key 50 recommended to be operated next among the plurality of operation keys 50 is different from the lighting color of the operation key 50 not recommended to be operated next.
Alternatively, the operation control unit 12 may control the operation unit 11 so that the operation key 50 recommended to be operated next among the plurality of operation keys 50 blinks, and the operation key 50 not recommended to be operated next does not blink.
As described above, by controlling the operation unit 11 so that the lighting state of the operation key 50 recommended to be operated next among the plurality of operation keys 50 is different from the lighting state of the operation key 50 not recommended to be operated next, the operator can easily find the operation key 50 recommended to be operated next among the plurality of operation keys 50. This can facilitate the operation of the welding machine 10 by the operator.
