Welding program production system and welding program production method
Provided is a welding program production system that can increase efficiency of a welding operation by a welding robot. The welding program production system includes a display control unit that causes a plurality of candidate welding lines detected on the basis of an image of a photographed object to be welded to be displayed in superimposed relation on the image, an input receiving unit that receives an input to select the welding lines from among the plurality of candidate welding lines and an input to specify a welding order and a welding direction for each of the selected welding lines, and a program production unit that produces a welding program on the basis of the specified welding order and welding direction.
1. A welding program production system comprising:
a determination unit that determines a weldable range of a welding robot based on a position at which the welding robot is to be disposed in relation to an object to be welded and a welding reach within a range of a welding torch disposed on a welding robot manipulator;
an image sensor that captures an image of the object to be welded;
a display control unit that causes a plurality of candidate welding lines detected based on the image of the object to be welded that is present within the determined weldable range to be displayed superimposed upon the image;
an input receiving unit that receives, from a user, a plurality of inputs to select the welding lines from among the displayed plurality of candidate welding lines, wherein the plurality of inputs comprises a first input to sequentially specify a welding line order and a second input to specify a welding direction for each of the selected welding lines; and
a program production unit that produces a welding program on the basis of the specified welding order and welding direction.
2. The welding program production system according to claim 1 , wherein the input receiving unit receives, as the input to specify the welding direction, an input to specify a welding starting position and a welding ending position.
3. The welding program production system according to claim 1 , wherein the input receiving unit receives, as the input to specify the welding direction, an input to trace each of the welding lines.
4. The welding program production system according to claim 1 , further comprising:
a welding line detection unit that calculates, based on the image, coordinate data corresponding to the object to be welded and detects, based on the coordinate data, the plurality of candidate welding lines.
5. A welding program production method to be implemented by a processor, the method comprising:
obtaining an image of an object to be welded;
detecting a plurality of candidate welding lines based on the image;
determining a weldable range of a welding robot based on a position at which the welding robot is to be disposed in relation to the object to be welded and a welding reach within a range of a welding torch disposed on a welding robot manipulator;
displaying the plurality of candidate welding lines detected based on the image of the object to be welded that is present within the determined weldable range-of the welding robot superimposed upon the image;
receiving, from a user, a plurality of inputs to select welding lines from among the plurality of displayed candidate welding lines, wherein the plurality of inputs comprises a first input to sequentially specify a welding line order and a second input to specify a welding direction for each of the selected welding lines; and
producing a welding program on the basis of the specified welding order and welding direction.
