Description

Technical Field

[0001] The utility model relates to the technical field of welding robots, in particular to an automatic cleaning device for welding robots. Background Art

[0002] A welding robot is an industrial robot engaged in welding (including cutting and spraying). Its welding gun head is generally detachable. According to the definition of the International Organization for Standardization, industrial robots belong to standard welding robots. Industrial robots are multi-purpose, reprogrammable automatic control operating machines 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, which can be connected to different tools or end effectors; a welding robot is an industrial robot with a welding clamp or welding (cutting) gun installed on the end axis flange, so that it can perform welding, cutting or thermal spraying. During the welding process of the welding robot, the molten metal welding slag will be deposited and solidified at the gun head of the welding gun, which is very unfavorable to the welding process, affecting the appearance and quality of the welding process, and causing certain damage to the gun head.

[0003] After searching, a lubricating oil proportioning and blending device disclosed in the prior art (Announcement No.: CN217193464U) records that "a supporting square plate is arranged on the top of the supporting plate, a storage box and a first supporting long rod are arranged on the upper surface of the supporting square plate, a water pump is arranged on the inner bottom wall of the storage box, a telescopic delivery pipe is arranged on the top of the water pump, a curved connecting pipe is arranged at one end of the telescopic delivery pipe, and a spray head is arranged at one end of the curved connecting pipe; a first supporting cylinder is arranged on the upper surface of the supporting long plate, a supporting frame is arranged inside the first supporting cylinder, and the first supporting cylinder is rotatably connected with the second transmission gear and the supporting plate respectively"; the device is operated by an electric telescopic rod, a telescopic delivery pipe, a first transmission gear and a second transmission gear. With the coordinated setting, the spray head can be moved vertically during use, thereby achieving the purpose of high cleaning quality. However, in actual use of the device, the second transmission gear rotates along the first support cylinder under the meshing action, and the support disk and the spray head rotate synchronously therewith. Therefore, the line corresponding to the spray cleaning structure will also rotate on the outside of the first support cylinder, and then will be synchronously wound around the outer side of the first support cylinder or the third support cylinder. Once the worker is negligent and the support disk rotates too many times in the same direction, the line is easily stretched due to excessive winding, and there will be a corresponding risk of breakage with subsequent rotation. At the same time, the rotating line will also increase the probability of interfering with the meshing of the first transmission gear and the second transmission gear, making the device extremely prone to corresponding failures.
