Problems solved by technology

However, because the scanner controller cannot always grasp how much the robot's current position deviates from the ideal value, the machining results sometimes deviate
In addition, there are also cases related to the OT (over-standard) of the scanner

Abstract

Provided are a scanner controller and a scanner control system. The scanner controller analyzes a position instruction in which a position in a world coordinate system and a position in a local coordinate system of a path of laser light are associated with each other and creates a movement command for a drive unit of a scanner based on the position of the local coordinate system. Further, the scanner controller calculates the current position of the scanner in the local coordinate system based on the position and attitude of a robot in the world coordinate system and the position in the world coordinate system in accordance with the position instruction. When the distance between the calculated position of the local coordinate system and the position in the local coordinate system in accordance with the position instruction is below a predetermined threshold, the scanner controller then determines to start machining and performs control of a drive unit of the scanner.

Description

technical field [0001] The present invention relates to scanner controllers and scanner control systems. Background technique [0002] The technique of welding by irradiating a laser beam from a position away from the workpiece is called remote laser welding. In remote laser welding, there is a galvano scanner in one of the units controlling the machining path. A galvano scanner (hereinafter, simply referred to as a scanner) operates one or more mirrors (for example, two mirrors in the case of laser control in the XY direction) in an optical system for laser light to operate any The path scanning laser device. A remote laser welding robot system in which this scanner is mounted on the front end of the robot, that is, the manipulator part, has been put into practical use (see Figure 7 ). In the remote laser welding robot system, since the scanner is operated while moving the robot, welding can be performed with a more complex processing path than in the case of a single s...
