Description

Technical Field

[0001] The present invention relates to the technical field of industrial lenses, and in particular to an industrial lens for industrial visual inspection. Background Art

[0002] As the core component of the vision system of mechanical equipment, industrial cameras play a vital role. They not only play an irreplaceable role in many fields such as automated production lines, precision testing, and quality control, but also significantly improve the performance of machine vision systems with their unique technical advantages. Compared with the common civilian cameras in daily life, industrial cameras show more outstanding performance characteristics, including high image stability, high transmission capacity, and high anti-interference ability. These characteristics enable industrial cameras to capture clear, accurate, and stable image information in complex and changing working environments, providing a solid foundation for subsequent image processing and data analysis;

[0003] However, in the actual application of industrial cameras, most industrial cameras use a threaded connection between the lens and the camera body. The specific operation of this connection method is to set an external thread at one end of the lens and a corresponding internal thread at one side of the camera body. Through the mutual cooperation between the external thread and the internal thread, the lens can be tightly connected to one side of the camera body.

[0004] However, the initial matching position between the internal and external threads is often difficult to determine quickly, and industrial cameras often need to use different types of lenses when capturing images of different products. Therefore, frequent replacement of lenses has become a normal phenomenon in the application process of industrial cameras. During the frequent replacement of lenses, the internal and external threads will experience repeated friction and wear, which will cause thread stripping, making the connection of the lens on the camera body side unstable and not firm enough, thus affecting the shooting effect of the industrial camera; in addition, during the inspection process, the inspection object may be improperly placed due to external factors, causing the position to shift, thereby exceeding the inspection range of the inspection lens, making it impossible for the inspection lens to accurately inspect the inspection object.
