[0002] Welding robots are an important equipment in the field of industrial automation. They combine robotic technology and welding processes to automatically perform welding tasks. Welding robots are usually composed of robotic arms, control systems, welding power supplies, sensors, and welding tools. They are widely used in many industries such as automobile manufacturing, aerospace, shipbuilding, and home appliance production.

[0003] Nowadays, when cleaning the welding gun of a welding robot, it may not be possible to clean it repeatedly, resulting in small debris not being cleaned up, which will affect the welding work. The welding slag, spatter and residue generated during the welding process may clog the nozzle and conductive nozzle of the welding gun, hindering the flow of shielding gas and the feeding of welding wire, resulting in unstable welding arc. Therefore, a fast gun cleaning mechanism for a welding robot is proposed. Utility Model Content

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] 1. In the utility model, a cleaning component is provided. When the welding gun of the welding robot needs to be cleaned, the welding gun is placed in the fixed cylinder on the fixed frame by controlling the robot. At this time, the driving motor on the motor plate is started, and the driving motor drives the driving rod to rotate, the driving rod drives the worm to rotate, the worm drives the worm gear to rotate, the worm gear drives the rotating column to rotate, the rotating column drives the reciprocating screw to rotate, and the reciprocating screw drives the threaded sleeve to move back and forth through the thread. At the same time, the threaded sleeve drives the circular brush to clean the outer surface of the welding gun back and forth through the connecting rod. At the same time, the reciprocating screw drives the cleaning rod to rotate, and the cleaning rod drives the cleaning brush to clean the hole of the welding gun. Cleaning the welding gun can remove the welding slag and spatter inside the nozzle, ensure that the shielding gas can flow smoothly, and cleaning can reduce welding defects caused by welding slag, which helps to maintain the performance and welding quality of the welding robot.

When the gear on the half gear contacts the toothed belt, the half gear drives the toothed belt to move, and the toothed belt drives the vibration rod to move. The vibration rod squeezes the telescopic spring through the ring. When the gear on the half gear falls off the toothed belt, the vibration rod is driven by the elastic force of the telescopic spring through the ring to hit the lower surface of the collection trough. The continuous impact and vibration accelerate the debris to fall into the collection trough. Collecting welding debris can reduce clutter in the workplace, create a tidier working environment, prevent debris from entering the interior of mechanical equipment, and reduce equipment failures and maintenance needs.
