[0003] The patent with publication number CN 215432212 U discloses a welding robot, which includes a welding robot body, a welding arm of the welding robot body is fixedly sleeved with a fixed circular ring, a surface of the fixed circular ring is sleeved with a cover, the cover and the fixed circular ring are connected by multiple fixing mechanisms, a plurality of fixed pipes are installed through the surface of the cover, and electric fans are installed inside the plurality of fixed pipes by screws. The device is provided with an electric fan and an activated carbon filter, and the electric fan transports the gas generated by welding to the inside of the box through a gas pipe. After the gas passes through the activated carbon filter, the activated carbon filter purifies the harmful gas in the gas, thereby improving the cleanliness of the gas when it is discharged from the box, and improving The device improves the air quality in the working environment and protects the workers. However, the device has the problem of fixing a circular ring on the welding robot body and then fixing the cover on the circular ring to slow down the diffusion of the welding gas and absorb it. However, the welding gas is not the only one that affects the health of the personnel during the welding process. The welding light generated by the personnel still causes great harm to the eyes of the personnel. In addition, the fixed-size cover cannot ensure that the diffused welding gas is completely absorbed. If the cover is larger, the welding head end of the welding robot body will be heavier, thereby affecting the welding. For this reason, a welding robot is proposed to solve the problem that the existing welding robots are difficult to handle harmful substances such as the light generated by welding.
