Detailed Description
Hereinafter, a wireless remote controller for a welding machine and a welding torch that are used for arc welding and that can be attached to and detached from a welding torch that emits an arc will be described with reference to the drawings.

Fig. 4B is a sectional view showing the remote controller for the welding machine mounted on the second bracket of the torch bracket.

The welding machine remote controller 1 shown in fig. 1A, 1B, 2A, 2B, 2C, and 2D is a wireless welding machine remote controller 1 that is attachable to and detachable from the welding torch 19 shown in fig. 3A, 3B, and 4A. The welding machine remote controller 1 includes a wireless transmission/reception unit 2, an operation unit 3, a display 7 as a display unit, and a photovoltaic element unit 4. The wireless transmitter/receiver 2 transmits and receives a signal directly or indirectly to a welding power supply not shown. The operation unit 3 is used to set display switching and welding conditions. The display 7 is provided above the operation unit 3 and displays a set value of the welding condition. The photovoltaic element section 4 is disposed on the rear surface side facing the display 7, and can generate power by light 22, which is arc light generated by arc irradiation 21 (see fig. 4A) of the welding torch 19, or light such as illumination light during standby.
The welding-machine remote controller 1 further includes an external connection unit 5 and a charging unit 6. When the remaining amount of power of charging unit 6 is small and emergency charging is necessary, or when communication with an external device is necessary by wired connection, external connection unit 5 is connected to an external charger or an external device by wired connection. The charging unit 6 charges the electric power generated by the photovoltaic element unit 4 or charges the electric power received from an external device via the external connection unit 5.
In the present embodiment, the photovoltaic element section 4 is disposed in parallel with the display 7 disposed on the front surface side. However, the light source is not limited to this, and may be disposed obliquely so as to be close to the perpendicular direction with respect to the light 22 so as to effectively receive the light 22 generated by the arc irradiation 21, illumination light during standby, sunlight, or the like.
The welding-machine remote controller 1 further includes a clamp portion 10 as an attachment portion, and the clamp portion 10 is provided on a rear surface side facing the operation portion 3 below the photovoltaic element portion 4 and is attachable to and detachable from a welding torch 19 or a pocket 23 (see fig. 6) of an operator. The clamping portion 10 has an opening 25 and a folded-back bent portion 24 located on the opposite side of the opening 25. The photovoltaic element section 4 is disposed above the upper end (the folded-back bent section 24) of the nip section 10 so as not to be shielded from light by the nip section 10.
Further, on the back surface side of the welding-machine remote controller 1 on the opening 25 side of the clamping portion 10, a semi-cylindrical projecting portion 11 is provided at a position where the distance from the apex of the folded-back bending portion 24 of the clamping portion 10 is substantially the same in accordance with the attachment length L of the attachment piece 26 of the welding-machine remote controller 1 of the second bracket 14, so that the welding-machine remote controller 1 and the attachment piece 26 of the second bracket 14 can be engaged with each other by the elastic force of the clamping portion 10.
This allows the clamping portion 10 and the projection 11 to engage with each other by vertically clamping the torch holder 12 between the clamping portion 10 and the projection 11. As a result, the projection 11 can be pressed by the elastic force of the clamping portion 10, and the welding-machine remote controller 1 can be stably attached to the torch holder 12 in a removable manner in a three-point support manner. Specifically, it is possible to prevent welding torch 19 from accidentally dropping from welding torch 19 due to positional displacement of welding torch 1 with respect to welding torch 19 to which welding torch 1 is attached to welding torch bracket 12, which is caused by operation of operation switch 8 of operation unit 3.
In the present embodiment, the distance from the folded-back bent portion 24 to the protruding portion 11 of the clip portion 10 is the same as the length L of the attachment piece 26 of the second bracket 14. However, without being limited to this, the distance from the folded-back bent portion 24 to the protruding portion 11 may be longer than the length L of the attachment piece 26 as long as the attachment piece 26 of the second bracket 14 can be held by the clip portion 10. In either case, when the welding-machine remote controller 1 is attached to the torch holder 12, the attachment piece 26 of the second holder 14 is accommodated in the internal space of the clamping portion 10 (the space between the folded-back bent portion 24 and the protruding portion 11). At this time, the protrusion 11 functions as a stopper for preventing the attachment piece 26 of the second bracket 14 from moving from the inner space of the clamping portion 10 to the outside. Therefore, the welding machine remote control 1 can be prevented from accidentally falling from the welding torch 19.
Further, the operation unit 3 includes: a plurality of operation switches 8 arranged in a single row vertically; and a projecting mark 9 serving as a position indicator of the operation switch 8.
Each operation switch 8 is not limited to this, but is substantially coplanar with the surface of the housing 27 of the remote controller 1 for a welding machine. That is, the surface of each operation switch 8 and the surface of the housing 27 are substantially in the same plane. On the other hand, the marker 9 protrudes from the surface of the housing 27. In other words, the operation switches 8 protrude relatively to a recognizable extent from the surface thereof. Accordingly, the operator can easily recognize the marker 9 even with a glove, and as a result, can easily recognize the position of each operation switch 8.
In the present embodiment, the plurality of operation switches 8 are arranged in a single row along the upper and lower sides. This makes it possible to make the remote controller 1 for a welding machine slim. In general, during a welding operation, an operator holds the torch handle 20 of the welding torch 19 with one hand and holds the welding mask with the other hand. The operation switch 8 is operated by the thumb of the hand holding the torch handle portion 20. By making the welding-machine remote controller 1 slim, the operation switches 8 can be arranged within a range easily reached by the thumb of the operator. Further, by arranging the plurality of operation switches 8 in a single row, the size of each operation switch 8 can be increased as compared with the case where the operation switches are arranged in a plurality of rows. Therefore, the operator can easily operate the operation switch 8 even with the glove.
In the present embodiment, the marker portions 9 are disposed on both the right and left sides of each operation switch 8. Therefore, in both the right-handed setting shown in fig. 3A and the left-handed setting shown in fig. 3B, either the right or left part of the marker 9 can be disposed within the reach of the thumb of the operator.
In the present embodiment, the marker 9 is disposed separately from each operation switch 8 at a position apart from each operation switch 8. That is, the marker 9 is not integrated with each operation switch 8. This can avoid a situation in which the operator has erroneously operated the operation switch 8 when the operator has fumbled and confirmed the position of the marker 9.
The shape of the protruding mark 9 is a quadrangular shape in the present embodiment, but may be a semicircular shape or a triangular shape.
Further, the operation unit 3 includes a display 7 as a display unit for displaying a set value of the welding condition, an actual output at the time of welding, a remaining amount of charging power of the charging unit 6, and the like. The display 7 is configured by an electronic paper type capable of being electrically rewritten and capable of maintaining display even when power is turned off, a memory liquid crystal type in which liquid crystal pixels have a memory effect and capable of maintaining display even when power is turned off, or the like. This allows the display 7 to retain the display content once displayed even when power is not supplied, and therefore, low power consumption can be achieved. Further, charging unit 6 is formed of a capacitor, a lithium secondary battery, or the like, and is small, thin, and lightweight.
Next, the torch holder 12 for attaching the welding-machine remote controller 1 to the welding torch 19 according to the present embodiment will be described with reference to fig. 3A, 3B, 4A, 4B, and 5.
In fig. 3A, 3B, 4A, 4B, and 5, the torch holder 12 for attaching the welding machine remote controller 1 to the welding torch 19 is a torch holder 12 that enables the welding machine remote controller 1 to be attached to either the left or right of the welding torch 19 in accordance with the dominant hand of the operator. The torch holder 12 is configured such that the welding machine remote controller 1 is detachably attached to a side surface of the welding torch 19, and the photovoltaic element portion 4 provided on the back side of the display 7 of the welding machine remote controller 1 faces a welding portion during arc welding.
Thus, during arc welding, welding torch 19 can receive arc light from the welding site at photovoltaic element portion 4 of welding machine remote controller 1, and can be efficiently charged. In addition, during the welding operation, the operator can easily change the welding conditions by operating the operation unit 3 of the welding-machine remote controller 1 while holding the welding torch 19 and charging the vicinity of the welding portion with the arc light.
As described above, the welding-machine remote controller 1 is not attached to the upper side or the lower side of the welding torch 19, but is attached to the side surface. This can prevent the remote controller 1 for the welding machine from interfering with the work.
The welding-machine remote controller 1 is detachably attached to the welding torch 19. Thus, when the welding-machine remote controller 1 is not necessary, the welding-machine remote controller 1 can be removed. For example, when welding is tried under a plurality of different welding conditions in order to obtain an optimal welding condition, the remote controller 1 for a welding machine is used. On the other hand, when welding is performed under the optimal welding conditions after the optimal welding conditions are obtained, the remote controller 1 for the welding machine is not necessary. The welding workability can be improved by removing the welding-machine remote controller 1.
The torch holder 12 includes: a first bracket 13 fixed to the welding torch 19 by sandwiching a torch handle portion 20 of the welding torch 19 from left and right; and a second bracket 14 attached to the first bracket 13 and including an angle adjustment unit 16 for adjusting an attachment angle so that light 22 generated by arc irradiation 21 from a welding torch 19 can be effectively received
The first holding piece 28 and the second holding piece 29 each have a fixing portion 15 for fixing the second bracket 14 in cooperation with the angle adjusting portion 16. That is, the first bracket 13 has fixing portions 15 on both left and right sides thereof. Thus, the second bracket 14 can be selectively fixed to either the left or right of the first bracket 13.
The first clamping piece 28 and the second clamping piece 29 further have fitting portions (e.g., holes or cutouts) 31, and the fitting portions 31 are fitted to fitted portions (e.g., protrusions) disposed on the left and right side surfaces of the torch 19, respectively. This can prevent the first bracket 13 from being displaced from the welding torch 19. The fitted portion may be a concave portion and the fitting portion 31 may be a convex portion.
The angle adjusting portion 16 of the second bracket 14 includes a plurality of reference fixing portions 17 serving as a rotation base shaft, and a plurality of arc-shaped long hole fixing portions 18 fixed by sliding in the rotation direction.
The fixing portion 15 of the first bracket 13 for attaching the angle adjusting portion 16 and the reference fixing portion 17 of the second bracket 14 is formed in an elongated hole shape capable of sliding the second bracket 14 holding the welding-machine remote controller 1 in the front-rear direction in accordance with the length of the fingers of the operator.
The angle adjusting portion 16 has a structure in which two arc-shaped elongated hole fixing portions 18 are disposed between two reference fixing portions 17.
As described above, the wireless remote controller 1 for a welding machine of the present embodiment, which is attachable to and detachable from the welding torch 19 for irradiating an arc, and the welding torch 19 to which the remote controller 1 for a welding machine is attached, have the photovoltaic power generation element section 4 capable of generating power by light such as arc light at the time of welding operation or illumination light at the time of standby, and have the charging section 6, the charging section 6 is capable of charging the power generated by the photovoltaic power generation element section 4 or charging the power via the external connection section 5, and the external connection section 5 is connected to an external device by wire and is capable of charging and communicating.
The welding-machine remote controller 1 further includes: a wireless transmission/reception unit 2 that operates using the electricity charged by the charging unit 6 and directly or indirectly transmits/receives a signal to/from the welding power supply; a display 7 that is a display unit that displays the welding conditions, output values, remaining charge amount of the charging unit 6, and the like; and an operation unit 3 for adjusting display switching and welding conditions.
The welding machine remote controller 1 further includes a projecting marker 9 in the vicinity of the left and right of the operation switch 8 of the operation unit 3, and the projecting marker 9 is used to identify the arrangement of the operation switch 8 of the operation unit 3 with a glove.
The welding-machine remote controller 1 is capable of adjusting welding conditions by hand of a welding torch even during welding operation, and has a holder 10, and the holder 10 can be easily attached to and detached from the welding torch 19, does not accidentally come off when attached to the welding torch 19, and can be inserted into a pocket or the like when being carried around.
The second bracket 14 for attaching the welding-machine remote controller 1 to the welding torch 19 is configured to be able to be reconfigured with respect to the torch handle portion 20, to be able to be attached to the left and right in accordance with the dominant hand of the operator, and to be able to perform tilt adjustment of the angle and the front-rear position in accordance with the length of the finger. Therefore, it is possible to provide the welding-machine remote controller 1 which is small, light, easy to handle, portable, and convenient to use, and which can reduce the burden on the operator due to the addition of the welding-condition adjustment function to the welding torch 19.
This makes it possible to reduce the size, weight, and operability, to provide portability and convenience, and to reduce the burden on the operator by adding the welding condition adjustment function to the welding torch 19. Further, since the welding-machine remote controller 1 is a separate independent structure from the welding torch 19, it can be attached and detached easily, and can be purchased separately when necessary.
In a conventional welding torch having a built-in welding condition adjuster, the handle portion of the welding torch is enlarged, and the control wire and the power supply wire for the welding condition adjuster are added to the torch cable portion, so that the handle portion and the torch cable portion are increased in mass, and the torch cable is thickened and strengthened because the control wire and the power supply wire for the adjuster are added to the torch cable, and the cable is hard to be withdrawn, so that it is difficult to continue a welding operation for a long time, and workability is deteriorated. Further, the setting unit of the welding condition adjuster incorporated in the welding torch is small, and when the welding condition is adjusted with a glove worn, it is difficult to adjust the welding condition, and the worker needs to remove the glove to adjust the welding condition, which reduces the workability. That is, a large burden is imposed on the operator. The remote controller for a welding machine and the welding torch according to the present embodiment can reduce such a burden. Further, the welding torch with the built-in welding condition adjuster is very expensive regardless of whether the welding torch itself is listed as a near consumable. The welding torch according to the present embodiment can also reduce such a problem.
Industrial applicability
According to the present invention, it is possible to reduce the burden on the operator due to the cable withdrawal caused by the increase in the mass and the increase in the shape of the welding torch, and to adjust the welding conditions while wearing gloves with the hands, without lowering the workability, even during welding. Further, since the welding torch is configured to be easily attachable to and detachable from the welding torch, the welding torch is portable and can be held by hand for operation, and the burden on the operator due to the addition of the welding condition adjustment function can be reduced. Further, the present invention is industrially useful because it is an independent structure that can be attached to and detached from a conventional welding torch.
