Abstract

This utility model relates to the field of automated production equipment technology, and in particular to an optical lens airtightness testing assembly. It includes multiple airtightness testing components, each comprising an airtightness testing base and an airtightness testing top cover, which are positioned vertically opposite each other. The airtightness testing base has a placement slot for placing the lens to be tested. A flat sealing ring is provided at the bottom of the placement slot, with the bottom edge of the lens abutting against the flat sealing ring. An O-ring is provided around the upper periphery of the placement slot, and a lower air passage is provided at the bottom of the placement slot. An upper air passage is provided inside the airtightness testing top cover, and the lower air passage is located below the central hole of the lens. Compared with existing technologies, this utility model's optical lens airtightness testing assembly achieves automated material handling, effectively reducing personnel requirements and improving production efficiency; it also effectively reduces misjudgments and improves testing accuracy.
