The threaded rod 36 can drive the extension plate 35 to slide in or out of the storage shell 34 through the connection with the threaded cylinder 37, so as to drive the camera 4 to approach or move away from the welding position; under the drive of the third motor 24, the U-shaped frame 21 rotates, which can drive the camera 4 to rotate. Under the drive of the second motor 23, the cylinder 1 rotates in the U-shaped frame 21, and the shooting angle of the camera can be adjusted. In this way, when the weld of the welding point is photographed by the camera 4, the position of the camera 4 can be adjusted arbitrarily; under the drive of the first motor 52, the ring frame 54 can be driven to rotate through the connecting frame 53, and the multiple filters 55 on the ring frame 54 can be adjusted to the front side of the camera 4 to filter the overexposure generated during welding. In this way, the normal shooting of the camera 4 can be ensured, so that the picture taken by the camera 4 can clearly show the welding seam, and the filter 55 can block the dirt generated during welding to prevent it from being contaminated on the camera 4, thereby protecting the camera 4; when the multiple filters 55 are driven by the first motor 52 and the ring frame 54 rotates, when the filter 55 contacts the cylinder 1, it will rotate to a horizontal state along with the curved outer wall of the cylinder 1, and when the filter 55 rotates to the horizontal state, it contacts the cleaning brush 8. At this time, the cleaning brush 8 rotates under the drive of the sixth motor 10 to clean the dirt adhered to the filter 55; the airflow generated by the fan 6 can flow to the shooting position of the camera 4 through the two air supply channels 7, so that the airflow can blow away the smoke and dust, ensuring the clear shooting of the camera 4, and when the airflow flows to the shooting position in front of the camera 4 through the two air supply channels 7, it can have a good cooling effect on the camera 4 itself, ensuring the stable shooting of the camera 4.

[0051] The present invention is used for a monitoring system for a welding process. A camera and a fan are installed through a provided cylinder. The airflow generated by the fan can flow to the shooting position of the camera via two air supply channels, so that the airflow can blow away the smoke and dust at the welding position, thereby ensuring clear shooting of the camera. Moreover, when the airflow flows to the shooting position in front of the camera via the two air supply channels, it can have a good cooling effect on the camera itself, thereby ensuring stable shooting of the camera.
