Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention particularly relates to a communication control device for welding equipment.

[0002]

2. Description of the Related Art Conventionally, in order to set, adjust, and change the control of welding equipment, that is, the welding output, the setting knob, adjusting knob, and changing knob of the control panel of the welding equipment are operated directly or by a cable. A device operated by using a remote controller is generally used. In particular,
In the case of large weldments, the welding operator and welding equipment are often separated from each other, and the welding operator sets welding conditions.
Since it takes a lot of time to go to the welding equipment due to changes and adjustments, it was common to keep the cable type remote controller at hand and operate it. FIG. 5 shows a configuration diagram in which a cable type remote controller 51 is attached to a conventional welding device 50. In addition to the above-mentioned device, a device for setting, adjusting, and changing the output of the welding device by using a wired communication cable from an external device such as a personal computer or a robot has also been used.

[0003]

When the welding equipment is controlled by the conventional device, particularly when the welding object is large, when the welding operator goes to the welding equipment, a large loss occurs in terms of time, and the welding is performed. Since the state could not be confirmed, this work was repeated, and there was a case where a larger time loss occurred. Further, when the cable type remote controller 51 is used, the welding operator can control the welding equipment at the welding site, so no time loss occurs, but the cable type remote controller 51 is installed from the welding equipment 50 to the work site. It is necessary to have a cable length according to the distance between the two, and if the distance becomes 30 m or 50 m, the cable weight will be close to 15 to 25 kg and it will be a heavy burden for the welding operator to carry it at the work site. It was. In addition, when the welding site is high or the footing is poor, the burden on the welding operator is further increased,
Cable type remote controller 51 including cable
Was required to be lightweight.

The cable type remote controller 5
When the welding conditions are controlled by 1, the welding conditions actually applied to the object to be welded, that is, the welding current, the welding voltage, etc. cannot be confirmed by the welding operator alone, although the set values of the welding conditions can be confirmed. Since it is not easy to check the construction specifications and construction results in this way, the construction quality often depends on the intuition of the operator, and the cable-type remote controller 51, etc. also ensures welding quality and saves welding data. The demand for confirmation and storage of actual welding data on the handheld device has increased.

Further, in terms of the quality of the product, it is an important management item to manage the welding construction conditions and the construction state, and the welding condition management and the actual working state management of the welding equipment 50 are performed by the welding equipment 50. There was a demand for the development of methods and devices that can be efficiently performed by the administrator.

Since most of the conventional welding equipment uses a common remote controller connected by a control cable, it is necessary to reset welding conditions and the like each time the welding equipment is used, and setting mistakes occur. Therefore, it was necessary to confirm the welding conditions.

The present invention solves the above problems and is a lightweight alternative to the conventional cable type remote controller as a means for controlling welding equipment. Moreover, the actual welding data can be read directly, the welding conditions can be managed, and the welding state can be controlled. It is an object of the present invention to provide a communication control device for welding equipment capable of monitoring the represented welding data and further storing it in other storage means.
