An adjustment assistance device is attached to a galvanometer scanner at a laser output side of the galvanometer scanner and used to adjust a tool coordinate system of the galvanometer scanner. The adjustment assistance device includes a light-receiving member having a light-receiving surface, which is at least one flat surface; and a connecting member that connects the light-receiving member to the galvanometer scanner and that enables the light-receiving surface to face a laser output port of the galvanometer scanner with a predetermined distance therebetween. The light-receiving member includes a light-receiving mark portion on the light-receiving surface, the light-receiving mark portion being a mark used to quantify a relative positional difference between a reference light-receiving position for light output from the laser output port and an actual light-receiving position at which the light output from the laser output port is received.

Laser machining device

To provide a spot welding system capable of shortening a cycle time of spot welding. A robot controller measures a time between a transmission time of a welding command signal to a welding machine and a reception time of a welding completion signal, after determining completion of pressuring by a spot welding robot, and subtracts a predetermined welding time from the measured time, thereby calculating a communication delay time between the robot controller and the welding machine. A spot welding system advances transmission timing of the welding command signal and the welding completion signal by the calculated communication delay time.

A laser processing robot system including a laser irradiation device that carries out an irradiation point shifting operation, a robot that moves the laser irradiation device, a laser irradiation device controller that controls the irradiation point shifting operation, and a robot controller that controls the robot. When moving the laser irradiation device by the robot, the robot controller instructs the robot on a plurality of first interpolated positions at every first interpolation period, and outputs a command value associated with the irradiation point shifting operation to the laser irradiation device controller at every second interpolation period shorter than the first interpolation period.

Laser processing robot system and control method of laser processing robot system

A spot welding system comprises a robot which changes a relative position of a spot welding gun and a workpiece. A control device drives an electrode drive motor so that a movable electrode of the spot welding gun abuts on the workpiece, and is formed so as to perform a position detection control which detects a position of the workpiece based on a position of the movable electrode when a state value of the electrode drive motor deviates from a predetermined range. An operation program includes a workpiece detection parameter for performing the position detection control. The workpiece detection parameter is set at each of welding points in the operation program.
