Description

Technical Field

[0001] The utility model relates to the field of optical lenses, in particular to a front cover glue dispensing groove. Background Art

[0002] The front cover of the optical lens is mainly used to protect the lens, which can effectively prevent dust, raindrops, fingerprints and other foreign substances from damaging the lens. Especially for some expensive high-end lenses, more attention should be paid to protection. At the same time, the front cover of the lens can also prevent light interference. When the camera is not in use, it can prevent light from entering the camera through the lens and affecting the quality of subsequent photos.

[0003] In the optical lens industry, in order to facilitate the assembly and installation of the front cover of the lens, glue is dispensed in the groove on the inner side of the front cover. However, in the prior art, due to the small size of the front cover of the lens, it is easily limited in structural space, which will lead to glue overflow during glue dispensing. In addition, the space of the conventional front cover glue dispensing groove is small, and it is difficult to control the amount of glue during glue dispensing, which increases the probability of glue overflow. Therefore, the stability of the lens performance will also be reduced after the subsequent installation of the front cover of the lens. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a front cover glue dispensing groove to solve the problems raised in the above-mentioned background technology. The utility model can effectively prevent or alleviate the problems of glue overflow and difficulty in controlling the glue amount.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a front cover glue dispensing groove, including a front cover glue dispensing groove body, the front cover glue dispensing groove body includes a lens front cover, a glue dispensing groove and a slope groove, the glue dispensing groove is opened on one side of the lens front cover, the glue dispensing groove is annular in structure as a whole, the slope groove is arranged on the surface of the glue dispensing groove, and a plurality of slope grooves are arranged, each slope groove is evenly distributed around the glue dispensing groove, and the middle of the lens front cover is arranged as a hollow structure.

[0006] Furthermore, four slope grooves are provided.

[0007] Furthermore, the interior of each of the slope grooves is interconnected with the internal cavity of the entire glue dispensing groove.

[0008] Furthermore, the glue liquid inside the slope groove permeates and overflows into the entire glue dispensing groove through capillary phenomenon.

[0009] Furthermore, the size specifications of each of the slope grooves are the same, and the front lens cover and the glue dispensing groove are concentric circle structures.

[0010] Furthermore, the devices to which the lens front cover is applied include mobile phones, cameras, surveillance lenses, and VR lenses.

[0011] Furthermore, the side of the slope groove is an arc-shaped structure.

[0012] Beneficial effects of the utility model:

[0013] 1. The front cover glue dispensing groove is provided with a plurality of slope grooves. After dispensing glue at the grooves, the glue can be infiltrated and overflowed into the entire circle of the glue dispensing groove by means of capillary phenomenon. By changing the structure, the problems of poor glue overflow and difficulty in controlling the glue amount can be effectively prevented or alleviated, and the glue amount can also be effectively controlled.

[0014] 2. The front cover dispensing groove can be applied to the front cover of mobile phone lenses, surveillance lenses, VR lenses and other equipment, and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides the following technical solutions: a front cover glue dispensing groove, including a front cover glue dispensing groove body, the front cover glue dispensing groove body includes a lens front cover 1, a glue dispensing groove 2 and a slope groove 3, the glue dispensing groove 2 is opened on one side of the lens front cover 1, the glue dispensing groove 2 is annular in structure as a whole, the slope groove 3 is arranged on the surface of the glue dispensing groove 2, and a plurality of slope grooves 3 are arranged, each slope groove 3 is evenly distributed around the glue dispensing groove 2, and the middle of the lens front cover 1 is arranged as a hollow structure.

[0022] In this embodiment, four slope grooves 3 are provided. The interior of each slope groove 3 is interconnected with the internal cavity of the entire glue dispensing groove 2. The glue liquid inside the slope groove 3 permeates and overflows into the entire glue dispensing groove 2 through capillary phenomenon. The size specifications of each slope groove 3 are the same, and the lens front cover 1 and the glue dispensing groove 2 are concentric circle structures.

[0023] In this embodiment, the devices used for the lens front cover 1 include mobile phones, cameras, surveillance lenses, and VR lenses. The side of the slope groove 3 is an arc-shaped structure.

[0024] like Figure 3-4 As shown, in the prior art, the shape of the glue dispensing groove of the front cover is a full-circle plane. The full-circle glue dispensing will easily cause the glue to bulge out of the glue dispensing groove 2, resulting in interference and damage, and the overall strength of the lens front cover 1 finally prepared is insufficient.

[0025] like Figure 1-2 As shown, in this embodiment, four slope grooves 3 are added inside the glue dispensing groove 2, and the glue liquid is dispensed into the slope groove 3 during glue dispensing. After glue dispensing, the glue liquid dispensed into the slope groove 3 can be uniformly infiltrated and overflowed into the entire circumference of the glue dispensing groove 2 by using the capillary phenomenon, and the overall glue amount injected into the glue dispensing groove 2 can also be effectively controlled. This effectively prevents or alleviates the problems of poor glue overflow and difficult glue amount control.

[0026] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
