It does not exist, nor does it fall within the scope of protection required by the embodiments of the present invention.

As shown in Figures 1 and 2, an embodiment of the present invention proposes a high-efficiency heat dissipation camera module. The high-efficiency heat dissipation camera module includes: a lens holder 100 and a lens 200 installed in the lens holder 100. The lens 200 There is a gap with the lens mount 100, and glue is contained in the gap between the lens mount 100 and the lens 200.

In the technical solution adopted in this embodiment, by setting a gap between the lens 200 and the lens mount 100, the lens 200 can be conveniently installed in the lens mount 100 during the later assembly, so as to avoid the problem of the lens 200. The lens 200 cannot be screwed into the lens holder 100 because it is too tightly matched with the lens holder 100. At the same time, glue is applied to the barrel of the lens 200. After the lens 200 is screwed into the lens holder 100, the glue applied It can be filled into the gap between the lens 200 and the lens mount 100. Before the glue is solidified, the lens 200 can be rotated under the action of external force, which is convenient for the staff to adjust the focus. After the glue solidifies, it ensures that the lens 200 and the lens The reliability of the connection of the lens mount 100 prevents the lens 200 from being too loosely matched with the lens mount 100 to cause out of focus, and improves the assembly yield.

In addition, in the technical solution of the present invention, the various features work together to integrate the high-efficiency heat dissipation camera module, simplify the assembly process of the rear end product line, ensure the accurate matching of the lens 200 and the lens holder 100, and improve Assembly yield.

Specifically, the high-efficiency heat dissipation camera module includes the lens 200 and the lens mount 100. The lens 200 includes a barrel and a lens. The outer surface of the barrel is provided with an external thread. The thread corresponds to an internal thread. It can be understood that the lens 200 and the lens mount 100 are threadedly connected.

Generally, the lens 200 and the lens mount 100 can be produced by different manufacturers. During the assembly process of the lens 200 and the lens mount 100, it is easy to fail or loose assembly, which affects the assembly yield. .

In this embodiment, in order to ensure that the lens 200 can be installed in the lens mount 100, the lens 200 and the lens mount 100 are set to have a gap. It can be understood that the external thread of the lens 200 and the lens The internal thread of the holder 100 is too loosely fitted, which ensures that the lens 200 can be installed in the lens holder 100. At the same time, in order to prevent the lens 200 and the lens holder 100 from being out of focus due to the loose assembly of the lens 200 The phenomenon is that glue is filled in the assembly gap between the lens 200 and the lens mount 100. Since the glue takes a certain time to solidify, the lens 200 can be allowed to rotate before the glue has solidified to facilitate focusing. At the same time, the glue After solidification, it can also ensure that the lens 200 and the lens mount 100 are tightly connected to prevent the formation of shadows, that is, through the gap between the lens 200 and the lens 100 and the glue filled in the gap between the two When assembling, the lens 200 can be well matched with the lens mount 100, which improves the assembly yield and efficiency.

The shadowless glue is also called ultraviolet glue, it must be through ultraviolet The glue can be cured under the premise that the radiation is irradiated to the glue, that is, the photosensitizer in the non-shadow glue and the ultraviolet rays will bond with the monomer. The non-shadow glue has strong viscosity, and the curing speed is also fast, generally 10~ It can be fully cured in 60 seconds. In the actual application process, you can choose according to your needs.

In this embodiment, a combination of thermal conductive gel and UV shadowless gel can be used. It can be understood that before focusing, the barrel of the lens 200 is coated with thermal conductive gel. After focusing, Then, the lens 200 and the lens mount 100 are fixed by applying UV shadowless glue.

Of course, in other embodiments, thermally conductive gel can be used alone, or UV shadowless gel can be used alone.
