Description

Technical Field

[0001] The utility model relates to the technical field of lens manufacturing, in particular to a lens assembly device with a waterproof sealing ring. Background Art

[0002] When assembling a waterproof lens with a sealing ring on the side wall of the lens barrel, the traditional assembly is to manually press the lens into the lens barrel with a sealing ring on the side wall. The traditional assembly has the following disadvantages: 1. The traditional assembly method has extremely low assembly efficiency and is time-consuming and labor-intensive; 2. The manual pressure is not evenly applied to each position of the lens, resulting in the lens tilting during the assembly process, causing the oxide layer on the inner side of the lens barrel to fall off, the sealing ring to break, and other phenomena, resulting in an extremely high defective rate; 3. Manual assembly requires grease to be applied to the sealing ring. The grease sticking to the side of the lens will cause watermarks on the lens that affect the appearance, and this cannot be avoided. Utility Model Content
