Abstract

The present invention provides a lens module which comprises a first lens and a second lens. Each of the first lens and the second lens comprises a central optical part and a periphery part surrounding the central optical part. The first lens is provided with a first surface facing to the second lens. The second lens is provided with a second surface facing to the first lens, wherein, the first surface of periphery part of the first lens is provided with a plurality of first projections which are installed separately. The second surface of periphery part of the second lens is provided with a plurality of second grooves corresponding with the first projections. The first projection of the first lens is matched in the second groove of the second lens thereby aligning the first lens with the light axis of the second lens. The invention also provides a method for manufacturing the lens module.

Description

technical field [0001] The invention relates to a lens module, in particular to a lens module composed of a plurality of lenses, and a manufacturing method of the lens module. Background technique [0002] A camera module usually includes at least one lens module and an image sensor opposite to the lens module, and is widely used in various camera devices. The camera module is built into various portable electronic devices, such as Mobile phones, camcorders, and computers are favored by many consumers. [0003] The lens module usually includes a lens barrel, a plurality of lenses and aperture plates and other components accommodated in the lens barrel. Each lens includes a central optical part and a peripheral part, and the peripheral part is used for fixing and assembling with the inner wall of the lens barrel or other components. At present, when these lenses are manufactured, the peripheral surface of each lens is usually formed as a smooth surface. When assembling, eac...
