BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gun exchanging device for a robot gun capable of testing the fluid supply to the gun when exchanging the welding gun.

[0002]

2. Description of the Related Art Usually, when replacing a gun in a robot gun, a robot gun device guided by a robot is a gun changer mounted on a gun stand.
Placed on the gun stand with the gun side gun changer including another gun side fluid supply unit connected to the gun, and the gun side gun changer becomes the robot side gun changer. The gun is being replaced by being connected.

[0003]

However, in such a gun exchanging device, when the gun side gun changer including the gun side fluid supply unit is placed on the gun stand with the gun connected, There is a problem that it is not possible to check whether or not the gun is connected so as to reliably receive the fluid from the gun side fluid supply unit.

The present invention has been made in view of the above problems of the prior art, and its object is to install a fluid supply connector and a fluid discharge connector on a gun stand. Therefore, it is an object of the present invention to provide a gun exchanging device for a robot gun, which can easily test the fluid supply to the gun when exchanging the welding gun.

[0005]

In order to achieve the above-mentioned object, a gun exchanging device for a robot gun according to the present invention is provided with a fluid supply connector and a fluid discharge connector on a gun stand, and a gun side is provided. The fluid supply unit is provided with a connector for connecting to each of the connectors.

[0006]

Since it is the gun exchanging device for the robot gun constructed as described above, when exchanging the gun, the robot gun device guided by the robot is located at the position of the gun changer on the gun stand. The gun side gun changer including another gun side fluid supply unit is placed on the gun stand with the gun connected.

At this time, the fluid supply connector and the fluid discharge connector installed on the gun stand are connected to the respective connectors provided on the gun side fluid supply unit.
Therefore, when the fluid is supplied to the fluid supply connector installed on the gun stand, the fluid is supplied from the fluid supply connector to the gun side fluid supply unit via the gun side connector, and then enters the gun. It is returned to the gun-side fluid supply unit and discharged from the gun-side connector through the fluid-discharging connector installed on the gun holder.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1, 2 and 3. In the figure, 1 is a water supply unit on the side of the gun, and many units, for example, a power supply unit 2
And the like constitute a gun side gun changer, and a gun (not shown) is connected via the substrate 3.

Reference numeral 4 denotes a robot side water supply unit, which constitutes a robot side gun changer together with a number of units, for example, a power supply unit 5, etc.
Connected to a computer (not shown).

Reference numeral 7 denotes a gun stand, and a gun side gun changer is placed on the upper plate 8 of the stand 7 for exchanging the gun. A water supply supply connector 10 having a water supply supply port 9 and a water supply discharge connector 12 having a drainage port 11 are installed on the stand 7.

In the gun side water supply unit 1, a water supply connector 14 connected to the connector 13 of the robot side water supply unit 4, a discharge connector 16 connected to the connector 15 and a water supply port 17 connected to the gun. And drainage port 18
And the connectors 19 and 20 connected to the water supply connector 10 and the water supply connector 12 installed on the stand 7 are provided.
The connector 19 is connected to the water supply port 17, and the connector 19
20 communicates with the drain port 18. Further, the robot side water supply unit 4 is provided with a water supply port 21 and a drainage port 22. Reference numeral 23 indicated by a virtual line is a connector formed on the gun changer on the gun side.

Since it is a gun exchanging device for a robot gun having the above structure, as shown in FIG.
The robot gun device in which the board 6 is connected to the robot arm and the gun is connected to the board 3, and the water supply unit 4 and the power supply unit 5 are connected to the water supply unit 1 and the power supply unit 2, respectively It is placed on the upper plate 8 of the gun stand 7.

Then, the water supply unit 4, the power supply unit 5, etc. are disconnected from the water supply unit 1, the power supply unit 2, etc., and the robot-side gun changer is pulled up by the robot. After that, the gun changer on the gun side and the gun are exchanged on the gun stand 7.

In this exchanged gun changer and gun, it is important to simply know if the gun is connected to reliably receive fluid from the gun side fluid supply unit. Therefore, a new gun stand 7
The connector 19 and 20 provided on the gun changer placed on the upper plate 8 of the gun and the water supply unit 1 of the gun are connected to the connectors 10 and 12 provided on the gun holder 7 as shown in FIGS. 1 and 2, respectively. Connected.

When water is supplied from the water supply port 9 in this state, water flows from the connectors 10 and 19 through the water supply port 17 into the gun (not shown), and from the drain port 18 to the connector.
Drain through 20 and 12.

Thus, the connectors-10, 19 and 1
It is possible to know whether the gun is connected so as to reliably receive the fluid from the gun side fluid supply unit by connecting 2 and 20 and simply connecting the water supply pipe to the water supply supply port 9 to supply water. . When this test is complete, the robot can lower the robot gun changer as shown by the arrow and connect the changer.

In this embodiment, the water supply connector is used for testing the water supply to the gun, but the present invention can be used not only for water supply but also for testing fluids such as air.

[0018]

Since the present invention is constructed as described above, a new gun connected to the gun-side fluid supply unit placed on the gun holder when the gun is replaced is simply the water supply port 9 It is useful as a gun exchanging device in a robot gun because it can be easily judged whether the connection is good or bad by only supplying water to it.
