Description

Technical Field

[0001] This utility model relates to a lens main tube filter correction mechanism. Background Technology

[0002] Typically, lenses use circular filters, which are assembled by applying adhesive around the entire circumference of the lens's adhesive groove. Square filters, however, require adhesive application to four different grooves on the lens. After application, the filter is attached to the square assembly area formed by the four grooves. In existing technology, during the conveyor belt transport of filters to the adhesive assembly station, vibrations and other factors can cause the filter to become slightly skewed after being picked up by the suction tube. Without correction, it cannot be properly attached to the lens barrel.

[0003] To address the above technical issues, this paper proposes a lens main tube filter correction mechanism. Utility Model Content
