Background Art In the modem industrial production field, particularly the special equipment field, welding quality is directly related to the safety and reliability of component products. To practically ensure that the component products have no quality flaws in the welding process, it is crucial to measure the weld width. For a long time, among many weld inspection means for stressed members, manual radiographic inspection occupies a dominant position. This conventional method highly depends on excellent technical experience of inspection and testing personnel. However, long-time intensive work makes the vision of the inspection personnel be easily fatigued.

When the sliding frame 20 moves from the relatively low ends to the relatively high ends, the sliding frame 20 drives the microfiber cloth 29 to move upwards, so that the microfiber cloth 29 is in contact with the lens of the vision sensor 9. The ascending motion of the microfiber cloth 29 may prevent a housing of the vision sensor 9 in contact with the microfiber cloth 29 from being in direct contact with the lens of the vision sensor 9. S4: In the process that the sliding frame 20 moves along the second guide rails 16, the gear ring 23 matches the rack 33 to rotate, the gear ring 23 rotates to drive the cleaning frame 24 to rotate, and the cleaning frame 24 drives the microfiber cloth 29 to rotate, so that the microfiber cloth 29 rotatably cleans the lens of the vision sensor 9, a condition that the picture photographed by the vision sensor is blurry or has dark spots as dust and dirt are attached to the surface of the lens of the vision sensor is avoided, and the measuring accuracy is improved.
