Abstract: An offline teaching device includes an acquisition unit that acquires position information of a plurality of welding lines of a workpiece and a scanning range of a sensor, a generation unit that generates a plurality of three-dimensional regions to be scanned, and a control unit that disposes the plurality of welding lines and the plurality of three-dimensional regions in a virtual space and highlights an overlapping region of each of the plurality of three-dimensional regions. The overlapping region is deleted, a new auxiliary screen in which the plurality of welding lines and at least one three-dimensional region after the deletion of the overlapping region are disposed in a virtual space is generated, and a teaching program for scanning the at least one three-dimensional region is created and output.

Abstract: An offline teaching device includes a first determination unit configured to determine whether data related to production of a workpiece to be produced by welding is changed, a second determination unit configured to determine, in a case where the first determination unit determines that the data is changed, a target whose relative position between the workpiece and a welding robot that executes the welding is changed based on the changed data, and a teaching program creation unit configured to create and output a second teaching program obtained by correcting a first teaching program for executing the welding, based on a displacement amount between a position of the target after the change of the relative position and a position of the target before the change of the relative position.

Abstract: An offline teaching device includes a memory storing a program, and a processor configured to execute the program stored in the memory. The processor is configured to acquire, from an inspection robot that inspects a workpiece to be produced by welding, information on positions of the workpiece and a welding robot that executes the welding, calculate a position of the workpiece and a position of the welding robot, convert a position of the workpiece with respect to the inspection robot into a position of the workpiece with respect to the welding robot, correct a position of a teaching point included in a welding teaching program used for the welding and correct a position of a teaching point included in an inspection teaching program used for the inspection of the produced workpiece, and output the corrected welding teaching program.
