Problems solved by technology

When ultraviolet light (also known as "UV light") is irradiated with UV glue for curing, because the lens barrel will cover part of the UV light, the UV glue located inside the lens barrel cannot be irradiated by UV light, resulting in incomplete curing of the UV glue. As a result, the lens barrel cannot be firmly fixed on the PCB or ceramic substrate, and eventually the original alignment will be shifted

Embodiment Construction

[0026] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] see figure 1 , the lens barrel structure 100 of the embodiment of the present invention includes a substrate 10 and a lens barrel 11 disposed on the substrate 10 . The substrate 10 is combined on one side of the lens barrel 11 . A light guide element 20 is disposed between the lens barrel 11 and the substrate 10 . Adhesive 15 is provided on the side of the light guide element 20 away from the substrate 10 , so that the lens barrel 11 and the light guide element 20 are relatively fixed. The side of the light guide element 20 close to the substrate 10 is provided with UV glue 16 to make the light guide element 20 and the substrate 10 relatively fixed. The light guide element 20 is made of UV light-permeable material.

[0028] In this embodiment, the lens barrel 11 is in the shape of a sleeve, and includes an arc-shaped ...

Abstract

A lens barrel structure includes a substrate, a barrel fixed on the substrate by an ultraviolet curing adhesive, and a light guide element between the barrel and the substrate. The light guide element is made of UV light penetrable material and includes light guide microstructures to diffuse UV light. The present disclosure also provides an assembly method for the lens barrel structure. The lens barrel structure ensures that the barrel can be firmly fixed on the substrate by the light guide element.

Description

technical field [0001] The invention relates to a lens barrel structure and an assembly method of the lens barrel structure. Background technique [0002] With the development of multimedia technology, digital cameras have been widely used by people, especially in recent years, portable electronic devices are also rapidly developing in the direction of high performance and multi-function. The combination of digital cameras and portable electronic devices has become the key to the development of mobile multimedia technology . The combination of a digital camera and a portable electronic device involves the assembly of a lens barrel on the digital camera and a printed circuit board (PCB) or a ceramic substrate on the portable electronic device. Wherein the lens barrel has a passage, and a lens is arranged in the passage to receive external optical images. An optical sensor is provided on a printed circuit board or a ceramic substrate, and the optical sensor converts received...
