Description

Technical Field

[0001] The utility model relates to the technical field of oiling devices, and more specifically to the technical field of oiling devices for protecting nozzles of welding robots. Background Art

[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, automatically controlled 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 an industrial robot with a welding tongs or welding (cutting) gun installed on the end axis flange, so that it can perform welding, cutting or thermal spraying.

[0003] The existing welding robot gun cleaning station is fixed in position, and cannot effectively spray protection against welding spatter liquid. The protection effect after spraying is not ideal, and manual observation of the protection nozzle (nozzle) status is required. When the welding gun protection nozzle is blocked, it needs to be manually disassembled and cleaned. Manual inspection and cleaning work reduces the efficiency of automated equipment and relatively increases the labor intensity of workers. Utility Model Content
