Lenses are an important optical component and are widely used in vision correction devices such as glasses. They are made of various materials and have clear functions, and are an indispensable part of modern people's daily life.

[0003] When personnel inspect the outer diameter of a lens, if the lens is not clamped, the lens may move due to slight vibration or touch during the inspection process, affecting the accuracy of the measurement. After the lens is placed on the inspection table and the inspection is completed, the static friction between the lens and the table and the smoothness of the lens itself will make it difficult to pick up the lens, which wastes personnel's time and increases their burden.
