Description

Technical Field

[0001] The invention relates to the technical field of visual detection, in particular to a device for automatically adjusting an imaging angle. Background Art

[0002] When visually inspecting the appearance of annular products, especially defect inspection of complex annular product surfaces, such as scratches, dirt, black spots, discoloration, color inconsistency, manufacturing defects, etc. on the surface of annular products, due to efficiency requirements and inspection quality requirements, each product annular surface needs to be inspected, which requires the product to be rotated 180 degrees in the horizontal plane. However, in existing inspection devices, some require manual rotation of each product 180 degrees in turn, some use multiple power systems to achieve 180-degree rotation of multiple products in the horizontal plane, and some set industrial cameras for inspection on different inspection surfaces of the product while the product remains unchanged. In these methods, manual steering will make the inspection inefficient, and multiple power systems and multiple cameras will complicate the entire inspection mechanism, occupy more space, and form mutual interference between multiple inspection stations, which will increase the inspection cost and is not conducive to use.

[0003] The existing publication number CN220894111U discloses a rotating mechanism for visual inspection of batch inspection of annular products, including a base and a driving motor. A plurality of driving shafts arranged in a row at intervals are rotatably arranged on the base, and each driving shaft is fixedly connected to a driven wheel; a driving wheel is fixedly connected to the output shaft of the driving motor, and the driving wheel is connected to the plurality of driven wheels through a belt. A plurality of pressure wheels that press against the belt are also rotatably arranged on the base at a position corresponding to each driven wheel, and the pressure wheels and the driven wheels are correspondingly in contact with the outer surface and inner surface of the belt; a placement table for placing annular products is also connected to the end of the driving shaft away from the base; the appearance of multiple surfaces of the annular products can be inspected in batches through a power system, which saves space, reduces costs, and improves inspection efficiency.

[0004] The existing technology can only realize the rotation of the product. However, if visual inspection of the inside and outside of the ring-shaped product is to be achieved, the camera needs to adapt well to the distance of the product. If good visual inspection is required, multiple cameras are still required. In order to solve the above technical problems, we propose a device that automatically adjusts the imaging angle.
