Abstract
A lens module includes a lens and a lens barrel receiving the lens therein with a gap maintained between a peripheral surface of the lens and an inner surface of the lens barrel. The lens barrel includes a plurality of hole portions with through holes defined therein and facing the peripheral surface of the lens, and a glue applied in the gap to adhere the lens to the hole portions.
Claims8
A lens module, comprising:
- a lens;
- and
- a lens barrel receiving the lens therein with a gap maintained between a peripheral surface of the lens and an inner surface of the lens barrel, the lens barrel comprising a plurality of hole portions with through holes defined therein, the hole portions facing the peripheral surface of the lens, and a glue applied in the gap to adhere the lens to the hole portions.
A method for assembling a lens module, the method comprising:
- providing a lens barrel and a tool, the lens barrel comprising a receiving space and a plurality of through holes formed in a sidewall thereof in communication with the receiving space, the tool comprising a syringe barrel having a plurality of glue ejecting hole, and an adjusting rod extendable out of or retractable into the syringe barrel;
- and
- placing a lens into the lens barrel with a gap maintained between a peripheral surface of the lens and an inner surface of the lens barrel, the through holes facing the peripheral surface the lens;
- determining if the lens is deviated from a central axis of the lens barrel;
- inserting the adjusting rod into the receiving space through a selected one of the through holes to align the lens with the central axis of the lens barrel if the lens is deviated from the central axis of the lens barrel;
- and
- injecting glue into the gap from the glue ejecting holes to secure the lens in position.
4 more elements
