Description

Technical Field

[0001] This utility model relates to a lens barrel adsorption and rotation mechanism. Background Technology

[0002] Typically, lenses use circular filters, which are assembled by applying adhesive around the entire circumference within the lens's adhesive grooves. Square filters, however, require adhesive application to four different grooves on the lens. After applying adhesive to one groove, the lens barrel needs to be rotated and adjusted before applying adhesive to the next groove. This rotation and adjustment process necessitates positioning the lens barrel. Current technology uses clamps to hold the lens barrel in place during rotation, but the clamping pressure on the lens barrel can easily damage its surface.

[0003] To address the above technical issues, this paper proposes a lens main barrel adsorption and rotation mechanism. Utility Model Content
