Description

A lens module

technical field

The utility model belongs to the technical field of optical imaging, in particular to a lens module.

Background technique

At present, the fixed structure of the lens module 10 used in cameras or other optical instruments in the industry is mainly fixed with glue, please refer to Figures 1 and 2, the structure includes a lens 11 and a lens holder 12, and the lens 11 consists of a lens barrel 111 is made up of some lens 112, has screw thread at lens barrel 111 outer wall and lens holder 12 inner wall, connects lens 11 by screw thread, then the lens barrel 111 of lens 11 and lens holder 12 upper end joints are dispensed and fixed. In this method, the lens is screwed into the lens holder 12 by threads first, and the optical effect is adjusted by the threads. When the optical effect is the best, then glue is dispensed at the joint between the upper end of the lens holder 12 and the lens barrel 111 to fix it. However, the application of this method will cause the following problems: when dispensing glue, due to thread fit, the glue is not easy to penetrate downwards, and the amount of glue used to fix the lens 11 and lens holder 12 is less, resulting in unreliable fixation and increased defective rate. If UV glue (ultraviolet glue, ie ultraviolet glue) is used to dispense glue at the junction, the ultraviolet light cannot be irradiated into the joint between the lens mount 12 and the lens 11, and the UV glue cannot be completely cured, so that the expected fixing effect cannot be achieved. If thermosetting glue is used to dispense glue at the junction, it is easy to stick the glue to the lens, resulting in poor appearance.

Utility model content

The utility model mainly provides a new type of lens module to solve the technical problem of unreliable dispensing and bonding between the lens and the lens holder in the prior art, and the specific scheme is as follows:

A lens module includes a lens and a lens holder, the lens includes a lens barrel and a lens, and the lens is installed in the lens barrel; the lens holder includes a lens holder peripheral wall, and the lens barrel is embedded in the lens In the seat, wherein, at least one of the outer wall of the lens barrel and the inner wall of the peripheral wall of the lens seat is provided with a groove, and the groove is located at the junction of the lens barrel and the lens seat.

In the utility model, a groove is arranged at the junction of the lens barrel and the lens seat, and the glue is accommodated in the groove. Enough glue can be fully in contact with the lens barrel and the lens seat, and the point between the lens and the lens seat is improved. Glue fixing reliability.

Further, the outer wall of the lens barrel has threads, and the inner wall of the peripheral wall of the lens holder has threads matched with the lens barrel. This facilitates the glue dispensing operation and has lower manufacturing costs.

Further, the grooves are arranged along the axial direction of the lens barrel or the peripheral wall of the lens seat, which facilitates the penetration of glue and improves the assembly speed of the lens module.

Furthermore, the groove extends downward at an angle to the axial direction of the lens barrel or the peripheral wall of the lens holder. Since the contact area between the glue and the lens barrel or the lens holder is further increased, this solution further improves the fixing reliability.

Further, the number of the grooves is multiple, preferably the number of grooves on the outer wall of the lens barrel or the inner wall of the peripheral wall of the lens holder is 4, and the grooves are symmetrically distributed on the outer wall of the lens barrel or the circumference of the lens holder the inner wall of the wall. This setting can not only increase the contact area between the glue, the lens barrel and the lens mount, but also maintain a balanced force, which further improves the fixing reliability.

Further, both the outer wall of the lens barrel and the inner wall of the peripheral wall of the lens holder have grooves, and the grooves are located at the junction of the lens barrel and the lens holder. Preferably, when the lens barrel and the lens holder are fixed, the lens The groove on the outer wall of the barrel corresponds to the inner wall of the peripheral wall of the lens holder and does not overlap with the groove on the inner wall of the peripheral wall of the lens holder. This solution further improves the fixing reliability.
