Lens module

Abstract

The invention belongs to the technical field of optics, and discloses a lens module. The lens module includes a lens and a barrel which are connected with each other, a glue groove is formed between the lens and the barrel, a collision avoidance groove is formed in the side wall of the barrel, the bottom of the collision avoidance groove is angled with the central axis of the barrel, and the distance between the bottom of the collision avoidance groove and the central axis of the barrel decreases gradually in the direction close to the lens. According to the lens module, the collision avoidance groove is formed in the side wall of the barrel, which makes it easy for a rubber needle to extend into the glue groove and inject a glue, and the case that the glue overflows on the surfaces of thelens and the barrel is reduced, thereby improving the cleanliness and aesthetics of the lens module; the glue can enter the glue groove completely for the bonding between the lens and the barrel, theglue is sufficient, which enhances the bonding firmness effect, and the torsion of the lens after glued is large, which reduces the deviation and defocusing of the lens in the actual use process, thereby improving the imaging quality.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a lens module. Background technique [0002] With the rapid development of multimedia technology, digital cameras, video cameras and mobile phones with cameras are more and more popular among consumers. Therefore, the demand for lens module products is gradually increasing, and higher requirements are put forward. [0003] Existing lens modules mainly include a lens and a lens barrel, which need to be bonded with glue. Since the lens covers the dispensing groove of the lens barrel, glue cannot be dispensed from the top surface of the lens, but can only be dispensed from the side. However, the distance between the lens and the top of the lens barrel is less than 0.5mm, and it is difficult for the operator to dispense glue, so that the glue needle used for gluing cannot be fully inserted into the glue groove, and the glue cannot completely flow into the glue groove, and the glue ...

AI Technical Summary

Problems solved by technology

Since the lens covers the dispensing groove of the lens barrel, the glue cannot be dispensed from the top surface of the lens, only from the side

However, the distance between the lens and the top of the lens barrel is less than 0.5mm, and it is difficult for the operator to dispense glue, so that the glue needle used for gluing cannot be fully inserted into the glue groove, and the glue cannot completely flow into the glue groove, and the glue can only be applied on the lens. On the side wall of the barrel, the glue will overflow on the surface of the lens and lens barrel, seriously affecting the appearance of the lens module

In order to solve the problem of glue overflow, we can only take measures to reduce the amount of glue dispensed. However, after the glue that completely flows into the glue tank is reduced, the torque of the lens after dispensing glue will be small, which will cause the lens to shift in the actual use of the lens module. problems, resulting in poor image quality
