Abstract

A device for use with a welding robot is provided which is capable of automatically separating the welding wire from the work even if the wire is caught on the work at the end of a welding operation. When the welding is finished, a means for detecting the sticking of wire applies a predetermined voltage between the work and the wire for a predetermined period of time, and produces a signal indicative of the wire sticking when a current flows between them. In response to this signal, wire-releasing means applies a second predetermined high voltage between the work and the wire to melt the bond between them (S3, S7).

That describes the t On the other hand, the operator uses the large voltage V applied to the workpiece and wire (both not shown) as a parameter for the automatic welding release operation via the CRTMDI 14, When V is to be applied, the welding time is set before the welding time is determined by setting the welding time of the welding detection circuit 3a of the welding machine 3 and the welding time of the welding machine 3a. Then, in order to end the welding of the 連 続 continuous welding area, the movement ft of the robot body 2 stops (Fig. 3 (Π), welding command from controller 電 圧 to welding 撐 3, voltage command). When the current command is lost (go to Fig. 3 (a) (c)), that is, when the arc end is reached, the CPU 10 sets the value of the counter provided in the memory 2 N is set to “0” (step S の in FIG. 2), and as shown in FIG. 3 (d), the set of the welding detection circuit 3 a of the welding machine 3 is set to the “定”. A command to switch to the T2 operation state is output (step S2). That is, the welding detection circuit 3a waits for a predetermined period of time, as in the conventional case, (see FIG. 3). A voltage for detecting wire welding is applied between the wire and the work to determine whether a current flows /), and a predetermined time T 2 is set. In this case, the CPU 10 outputs a wire welding signal when a current flows through the CPU 10. In step S3, the CPU 10 determines whether or not a welding signal has been output from the welding detection circuit 3a. It is determined whether or not the predetermined time ^ T 2 has elapsed (step S 4). When a welding signal is output within the set predetermined time PBT 2 as shown in FIG. 3 (e), the welding is performed. The detection circuit 3a is turned off (step s5, and then the counter H becomes the Wi 5t value. It is determined whether or not the value has reached (in this embodiment, “3”). If the value has not reached the predetermined value “3”, the welding release process is started.

At this time, unlike the normal welding execution, there is no need to send the wire, and therefore no current command is output. As a result, the wire is not fed, and in the state where the rod body 2 is also stopped, the set large voltage is applied between the wire and the work, and the welding portion between the wire and the work ( (Not shown) will be melted.
