Abstract: A laser machining robot system that simplifies programming of a scanner operation is provided. A laser machining robot system includes a robot controller that controls a robot that performs remote laser machining and a scanner controller that controls a scanner. The robot controller includes: a machining information input unit that inputs machining information; a G-code generation unit that generates a G-code program using the machining information; and a G-code communication unit that transmits the G-code program to the scanner controller. The scanner controller includes a scanner program processing unit that applies the G-code program as a scanner operation program for operating the scanner.

Abstract: In a conventional spot welding gun, since pressurizing force due to a movable electrode is measured by a pressure sensor at each of a plurality of attitudes, calibration work is complicated.A spot welding system 10 includes a spot welding gun having an opposite electrode 44, a movable electrode 48, and a drive part 52, a position detection part 54 that detects a position of the movable electrode 48, and a pressure change calculation part that calculates an amount of change between first pressurizing force at a first attitude and second pressurizing force at a second attitude based on a first position of the movable electrode 48 when the drive part 52 has been driven by a first pressurizing force command at the first attitude, a second position of the movable electrode 48 when the drive part 52 has been driven by the first pressurizing force command at the second attitude, and the first pressurizing force command. The first pressurizing force command and the first pressurizing force coincide with each other.

Abstract translation: 在传统的点焊枪中，由于通过压力传感器在多种姿态中的每一种测量由可移动电极引起的加压力，所以校准工作变得复杂。 点焊系统10包括具有相对电极44，可动电极48和驱动部52的点焊枪，检测可动电极48的位置的位置检测部54，以及压力变化计算部， 基于第一姿势下的第一加压力指令驱动驱动部52时的可动电极48的第一位置，以第一姿态的第一加压力与第二姿势的第二加压力之间的变化量， 驱动部52由第一加压力指令以第二姿势驱动时的可动电极48的第二位置和第一加压力指令。 第一加压力指令和第一加压力彼此一致。
