Description

Technical Field

[0002] Welding robots are industrial robots that perform welding (including cutting and spraying). According to the definition of the International Organization for Standardization (ISO), industrial robots belong to standard welding robots. Industrial robots are multi-purpose, reprogrammable automatic control manipulators with three or more programmable axes used in the field of industrial automation. In order to adapt to different uses, the mechanical interface of the last axis of the robot is usually a connecting flange that can be connected to different tools or end effectors. The welding robot is to install welding tongs or welding guns on the end axis flange of the industrial robot so that it can perform welding, cutting or thermal spraying.

[0003] At present, welding robots all use intelligent numerical control to control multiple robots for welding at the same time. Since smoke and harmful gases will be generated during the welding process, workers are required to control the control panel from a distance. In order to ensure the accuracy of the welding points, infrared point distance measuring devices are usually installed on the end shaft flange or welding gun of the welding robot according to actual conditions. During the welding process, flames or sparks will be generated when the welding gun is spot welding, which will splash onto the distance measuring lens, affecting the accuracy of the distance measuring device, thereby affecting the welding track of the welding robot, resulting in unqualified product welding.
