Problems solved by technology

Welding torch robot control is prone to collide with the workpiece during welding. If the robot continues to work and the wire feeder continues to feed wire, the workpiece and the welding torch will be severely damaged
The traditional welding torch is rigidly connected to the robot arm. Even if there is no serious collision or wire blockage during the welding operation, vibration or slight collision will inevitably occur. Long-term vibration or slight collision will affect the life of the robot welding torch

Abstract

The invention provides an anti-collision robot welding gun which comprises a welding gun body, a wire feed device, a robot arm and a master control system. The wire feed device is arranged at the rear end of the welding gun body and connected with the welding gun body through a cable, and the robot arm is used for controlling the action of the welding gun body. The wire feed device and the robot arm are connected with the master control system. An anti-collision sensor is further included, arranged between the welding gun body and the robot arm and used for inducting the collision force of the front end of the welding gun body, the anti-collision sensor is connected with the master control system, and the master control system receives the signal of the anti-collision sensor and controls the robot arm and the wire feed device to move in real time. The anti-collision sensor is added to the robot welding gun, the force in the collision process can be detected, collisions are buffered in time, an alarm is given to the master control system, and the master control system can carry out adjustment effectively in time when collisions happen in the welding process.

Description

technical field [0001] The invention relates to the technical field of robot welding torches, in particular to an anti-collision robot welding torch. Background technique [0002] Welding robots are industrial robots engaged in welding (including cutting and spraying). An industrial robot is a multipurpose, reprogrammable, automatically controlled manipulator with three or more programmable axes, used in the field of industrial automation. The welding robot is to install welding tongs or welding (cutting) guns on the flange of the final axis of the industrial robot, so that it can perform welding, cutting or thermal spraying. [0003] The robot welding torch is to install the welding torch on the terminal of the industrial robot, and the welding torch performs the welding operation under the control of the industrial robot. The general welding process is that the high-temperature melting welding wire is sent out from the contact tip of the welding torch, and a molten pool ...
