Problems solved by technology

Secondly, because there is no fixed-point glue injection position on the annular bump, the colloid must be coated around the inner wall of the lens barrel, which not only wastes colloid and dispensing time, but also causes damage due to too much colloid applied. Affects the light transmission area of ​​the entire lens module

Embodiment Construction

[0012] Such as figure 1 and figure 2 As shown, a lens module 6 provided by an embodiment of the present invention includes a lens barrel 1 and an optical element 3 (see Figure 4 ) and mirror holder 5. The optical element 3 is arranged in the lens barrel 1 , and the lens barrel 1 and the lens base 5 are screwed together.

[0013] The lens barrel 1 includes a focus ring 10 and a receiving portion 12 . The receiving portion 12 is a hollow cylinder. A light-transmitting through hole 10a is defined in the center of the focus ring 10 . The focus ring 10 is disposed at one end of the receiving portion 12 and forms a receiving space 13 together with the receiving portion 12 . The axis of the focus ring 10 is aligned with the axis of the receiving portion 12 and passes through the center of the light-transmitting hole 10a.

[0014] The focus ring 10 includes a pair of parallel positioning side surfaces 10b. The receiving portion 12 includes an outer wall 120 and an inner wall ...

Abstract

The invention relates to a lens module which comprises a lens barrel and a lens seat, wherein the lens barrel comprises a cylindrical accommodating part, the accommodating part comprises an internal side wall and an external side wall, and an external thread is arranged on the external side wall. A plurality of mutually spaced lug bosses extend from the top edge of the internal side wall along the direction parallel to the axis of the lens barrel. A spot gluing gap is formed in the position between every two adjacent lug bosses. The top edge of the internal side wall is provided with a glue injection notch penetrating into the internal side wall in the position corresponding to the middle part of each spot gluing gap. The lens seat comprises a screwed connection part, and an internal thread corresponding to the external thread is arranged on the screwed connection part.

Description

technical field [0001] The invention relates to a lens barrel and a lens module using the lens barrel. Background technique [0002] In existing lens modules, an annular protrusion is usually provided at the bottom edge surrounding the inner wall of the lens barrel. When the lens barrel is installed on the base, there is a distance between the lens barrel and the electronic components in the base, such as the image sensor, etc., through the annular protrusion. [0003] When it is necessary to dispense glue in the lens barrel to fix the optical element, the glue is coated on the inner wall of the lens barrel through the glue dispensing needle. However, if the flow of the glue is not properly controlled during the process of coating the glue, the residual glue will overflow onto the annular bump. When the lens module performs a focusing action, the colloid remaining on the ring-shaped protrusion is likely to contaminate the image sensor. Secondly, because there is no fixed-...
