[0027] 1. The present invention provides a flame retardant protective component at the outer end of the welding connector. The flame retardant protective cover protects the welding head during welding. The flame retardant protective cover effectively prevents the high temperature, welding slag splashing and fine slag dust generated during welding from damaging the welding head. The high temperature and harmful substances are isolated to ensure that the welding head can perform welding work stably for a long time, and the welding gun body and circuit are prevented from being damaged by high-temperature welding slag. The threaded disassembly connection between the flame retardant protective cover and the welding head is convenient for quick replacement or cleaning of the flame retardant protective cover when necessary. The protective effect of the flame retardant protective cover can significantly reduce the damage to the welding head caused by factors such as high temperature and welding slag, thereby extending the service life of the welding head and the entire welding system, and improving the safety of the welding operation.

[0028] 2. The present invention provides an in-place protection component on the outside of the flame-retardant protection component. After the welding robot body drives the welding head to move into position, the telescopic protection frame shrinks into the horizontal storage groove. During the process of the welding robot body driving the welding head to move to the welding position, the in-place protection component protects the welding head, effectively preventing the welding head from colliding with external objects during movement, thereby avoiding damage or deformation of the welding head due to collision, ensuring that the welding head remains stable during movement, ensuring the accuracy and quality of welding, and avoiding the welding head in a high-temperature state after welding to threaten the processing environment, thereby further improving the safety of the welding process. The use of the in-place protection component can ensure the smooth progress of the welding process and improve the welding work efficiency.

[0029] 3. The present invention provides a welding slag cleaning component on the inner side of the flame retardant protective cover. When the telescopic protective frame is reset after welding, it drives the welding slag cleaning component to clean the welding slag and residues on the inner wall of the flame retardant protective cover, and detects the damage or aging of the flame retardant protective cover. The welding slag and residues on the inner wall of the flame retardant protective cover are cleaned in time to prevent them from eroding and damaging the flame retardant protective cover, thereby improving the welding quality and extending the service life of the flame retardant protective cover. Cleaning the welding slag and residues can ensure that the protective performance of the protective cover is maintained, reduce production interruptions caused by equipment failure or maintenance, and improve production efficiency. Detecting the damage or aging of the flame retardant protective cover can timely discover potential safety hazards or performance problems, and avoid accidents or equipment failures during welding.

[0030] 4. The present invention installs an atomizing spray head on the inner side of the processing trough, and the external anti-splash spray is sprayed through the atomizing spray head to form a protective layer around the welding head, thereby reducing the direct contact between the spatter and the welding head during the welding process. The protective layer can prevent the spatter generated during welding from directly adhering to the welding head, thereby maintaining the cleanliness and integrity of the welding head and avoiding damage to the welding head or affecting the welding quality. The spraying of the anti-splash spray helps to cool the welding head after work, reduces the impact of spatter on the welding head, and enables the welding process to be carried out more stably, thereby improving the welding quality and making the welded part smoother and free of defects.
