Description

Technical Field

[0001] The utility model relates to the technical field of defect detection, in particular to an automatic vision defect detection device. Background Art

[0002] An automatic vision defect detection device is a process of detecting and analyzing the appearance and surface features of an object or product by using vision technology and related equipment to determine whether there are defects or flaws. In this process, devices such as high-definition cameras and image sensors are usually used to obtain the image information of the object, and then, with the help of image processing algorithms and software, these images are processed and analyzed. These algorithms can identify abnormal situations such as color differences, irregular shapes, texture changes, and dimensional deviations on the surface of the object.

[0003] The prior art such as the utility model with the publication number of CN216594843U, which relates to the technical field of vision detection devices, discloses an automatic vision defect detection device, including a chassis. The upper part of the side wall of the chassis is rotatably connected with a first rotating shaft. One end of the first rotating shaft is fixedly connected with a first motor. On both sides of the first rotating shaft, there are welded first bevel gears. The first bevel gears are meshed with second bevel gears. The center of the second bevel gears is welded with a second rotating shaft. One end of the second rotating shaft is welded with a third bevel gear. The third bevel gear is meshed with a fourth bevel gear. The center of the first bevel gears is welded with a third rotating shaft. The outer wall of the third rotating shaft is rotatably connected with a vertical plate. The bottom of the vertical plate is fixedly connected to the top surface of the chassis. A threaded through hole is opened inside the third rotating shaft. A threaded rod is threadedly connected inside the threaded through hole. One end of the threaded rod is rotatably connected with a clamping plate. This structure can perform rotational vision detection on metal parts without the need to turn them over, with high efficiency, and solves the problem that in the existing surface defect detection of metal parts, vision detection is used, but the existing detection of metal parts is carried out by turning them over one by one, requiring back-and-forth turning, resulting in low detection efficiency.

[0004] In daily work, it is found that when the above-mentioned automatic vision defect detection device is performing detection, although it can realize the flipping of the object to detect different surfaces, the clamping side of the object cannot be detected. Subsequently, it is necessary to manually readjust the placement angle of the object and perform multiple rotational detections again, resulting in a more troublesome use and low efficiency. Furthermore, when the existing automatic vision defect detection device is detecting, it is necessary to continuously flip the object for multi-surface detection, resulting in inconvenient use.
