Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic welding machine using a beam tracing machine.

Conventionally, automatic gas fusing machines have been available that use a so-called light beam tracer that moves along the pattern outline of a template drawn on a substrate, but this machine uses a pattern detection section of the light beam tracer and one or more The gas jetting nozzle and the gas jetting nozzle are attached to the same frame body, and the frame body is moved along the template drawn in the shape to be fused directly below the pattern detection part, thereby cutting the workpiece directly under the gas jetting nozzle. It is designed to be fused.

5. When applying a beam tracing machine to a welding machine, a different problem must be solved than that of the above-mentioned fusing machine.

The first is that the parts of the workpiece to be welded are not necessarily continuous along the contour of the workpiece, and the welding torch must be controlled to inject or stop each injection in order to perform welding intermittently. Things that must be done. Second, when the workpiece is a three-dimensional object, the direction in which the welding torch points must be changed depending on the location of the workpiece to be welded. The present invention solves these problems and provides 15 applications in the industrial field.
Especially if the beam is useful (intended to provide a sentry welder).

This invention connects a beam tracing machine body 1 that moves along the outline of a template drawn on substrate soil and a welding machine body 2 with a connecting rod 3, and also connects both bodies 201 and 2 in parallel and in the front, back, left and right directions. It is movably supported by a support device 4, and is equipped with a control device 6 for starting and stopping the movement of the beam tracing machine main body 1, and for controlling the injection and direction of the welding torch 5 of the welding machine main body 2. If it is a light beam (related to 25 patrol welding machines).

FIG. 1 and FIG. 2 show the structure of the apparatus according to the present invention.

In the figure, 7 is a mark 30 detection device that detects a reflective mark affixed on the substrate to give an input signal to the control device 6, and 8 is a drive mechanism of the beam tracing machine main body 1, which is driven by a roller at the lower end. It moves on the board.

9 is a detection unit that detects the outline of the template and provides a control signal to the drive mechanism 8; 10 is a 35 glass plate placed on the substrate on which the template is drawn; and 11 is a welding wire feed pipe. .

Further, A indicates a substrate, and B indicates a workpiece. An embodiment of the present invention will be described based on the drawings. For example, when welding the workpiece B on the right side of FIG.
3 is a straight welded part, A3 to A4 is a non-welded part, A4 to A5 is a welded part with curvature, A5 to A6 is a non-welded part,
A6 to A7 are straight welds, A7 to A8 are curved welds, A8 to A9 are straight welds, A9 to a
1 is the non-welded part, and when divided, the workpiece B
l7) Draw the same template as the peripheral part on the left board, and when the detection part 9 of the beam tracing machine main body 1 passes through the parts b1 to B9 corresponding to the a1 to A9, the welding torch 5 is ejected and In order to control the direction in which the tip points, for example, a reflective mark is attached, and this is detected by the mark detection device 7 to perform the control.

Note that the detection section 9 and the mark detection device 7 are provided at different locations on the beam tracing machine main body 1, so for example, when the detection section 9 passes through b1, the mark detection device 7 must be located at the location c1. Therefore, the positions of the reflective marks corresponding to b1 to B9 are c1 to C9. So, b! When the starting point of the beam tracing machine main body 1 is set as the starting point of the beam tracing machine main body 1, the movement of the beam tracing machine main body 1 and the welding machine main body 2 starts at the reflective mark c1, the gas injection from the welding torch 5, and the pointing direction of the welding torch are set to the workpiece to be welded. Rotate it along the shape of B.
When the detection part 9 comes to B2, the rotation of the welding torch 5 is stopped by the reflection mark C2, and the straight part is welded while the gas injection remains unchanged. At the point B3, the jetting of the welding torch 5 is stopped by the reflective mark C3, and the next point B4 is stopped.
At the point , the welding torch 5 is caused to inject gas and rotate by means of the reflective mark c. Thereafter, the ejection and rotation of the welding torch 5 in the pointing direction are similarly controlled, and the apparatus is stopped when the welding torch 5 returns to the reflective mark CL. Furthermore, since the linear velocity of movement of the beam tracing machine body 1 is almost constant, it is necessary to change the rotating speed of the welding torch depending on the difference in the curved portion of the template. This can be done arbitrarily depending on the settings.

As described above, according to the present invention, it is possible to realize an automatic welding machine using a beam tracing machine, which is particularly useful in the industrial field.
