Problems solved by technology

[0003] Although the robot system according to Japanese Patent Laid-Open No. 2008-43971 can emit a laser beam to a processing trajectory of an arbitrary shape in a state where the laser emitting device (laser emitting part) is positioned (stayed) at a designated position, there may be such a problem , that is, when the laser emitting device (laser emitting part) emits the laser beam in motion, the robot system cannot correctly emit the laser beam to the processing track of any shape

Embodiment Construction

[0022] The embodiments of the present invention will now be described with reference to the drawings.

[0023] First, refer to Figure 1 to Figure 3 The structure of the robot system 100 according to the embodiment of the present invention is described.

[0024] The robot system 100 according to the embodiment of the present invention is a robot system for remote laser welding, which emits a laser beam from a position spaced apart from a target workpiece (for example, a position spaced about 500 mm apart) to perform laser welding. The robot system 100 includes a robot 1, a robot control device 2 that controls the robot 1, and a teach pendant (programmed teach pendant) 3 that teaches the operation of the robot 1, such as figure 1 Shown in. The robot system 100 according to this embodiment further includes a laser scanner 4 for emitting a laser beam installed on the robot 1 and a laser oscillator 5 that supplies the laser beam to the laser scanner 4. The teaching pendant 3 is an exa...

Abstract

This robot system (100) includes a robot (1), a laser emitting portion (4) moved by the robot, emitting a laser beam to a target workpiece, and a control portion (27) controlling the laser emitting portion to emit the laser beam on the basis of information regarding an arbitrarily-shaped work locus and movement information of the laser emitting portion.

Description

Technical field [0001] The present invention relates to a robot system, and more specifically, to a robot system including a laser emitting part capable of emitting a laser beam. Background technique [0002] Robot systems including a laser emitting section capable of emitting laser beams are widely known. Japanese Patent Laid-Open No. 2008-43971 discloses a robot system including a laser emitting device (laser emitting section) capable of emitting a laser beam to a target workpiece. The robot system is formed to emit a laser beam to a processing track of an arbitrary shape in a state where the laser emitting device is positioned (stayed) at a specified position. [0003] Although the robot system according to Japanese Patent Laid-open No. 2008-43971 can emit a laser beam to a processing trajectory of any shape while the laser emitting device (laser emitting part) is positioned (stayed) at a specified position, there may be such a problem That is, when the laser emitting device (...
