[0002] Elevator rope is one of the important parts of elevators, which has a vital impact on the safety and performance of elevators. Therefore, the inspection standards of elevator ropes are very strict. After the elevator ropes leave the factory, they need to undergo a series of tests, mainly including appearance inspection, bending test, tensile test, magnetic particle inspection and other links. In the appearance inspection, the main inspection is to check whether there are cracks, deformation, rust, wear and other defects on the surface of the wire rope, as well as whether the pitch and tension of the rope are uniform. Therefore, the use of testing equipment is essential; As disclosed in the publication number CN216770470U, a detection device is disclosed for detecting workpieces with identification codes, including a jig, a first drive mechanism, an image pickup device, a second drive mechanism, a prism, and a third drive mechanism. The jig is used to place the workpiece, the first drive mechanism is connected to the jig to drive the jig to move in a first direction, the image pickup device is located above the jig to capture an image of the identification code of the workpiece, the second drive mechanism is connected to the image pickup device to drive the image pickup device to move in a second direction, the prism is located below the jig, the image pickup device captures the image through the prism, and the third drive mechanism is connected to the prism to drive the prism to move in the second direction so that the prism faces the identification code of the workpiece. The utility model adjusts the positions of the jig, the image pickup device, and the prism that carry the workpiece through the first drive mechanism, the second drive mechanism, and the third drive mechanism, so that the image pickup device can accurately capture the information of the identification code of the workpiece, thereby improving the working efficiency and accuracy of identification code detection; Another example is the publication number CN218511684U, which discloses a detection device, including a conveying component, a mounting bracket connected to the conveying component, and a visual detector and an optical detection component arranged on the mounting bracket; the visual detector is used to take photos and detect the workpiece to be tested, and the optical detection component includes a first detection probe and a second detection probe that are oppositely projected and spaced apart, and the first detection probe and the second detection probe are used to detect the opposite sides of the workpiece to be tested. Among them, the conveying component can drive the visual detector and the optical detection component to move according to the position of the workpiece, and adjust the detection position.
