The embodiment provides a lens module, which is used for imaging of a digital product, and as shown in fig. 1-2, the lens module comprises a lens 1 and a lens barrel 2 which are connected with each other, in order to realize tight connection between the lens 1 and the lens barrel 2, a glue groove 3 is formed between the lens 1 and the lens barrel 2, and an avoiding groove 4 is formed on the side wall of the lens barrel 2, so that a glue needle passes through the avoiding groove 4 and then extends into the space between the lens 1 and the lens barrel 2, and is used for injecting glue solution into the glue groove 3. Because the distance between the lens 1 and the top of the lens barrel 2 is small, in order to facilitate manual insertion of a rubber needle into the rubber groove 3, the groove bottom of the avoiding groove 4 is defined as a plane where the bottom of the avoiding groove 4 is located, the central axis of the lens barrel 2 is the central axis of the lens barrel 2, namely the central axis is located in a vertical plane and penetrates through the center of the end face of the lens barrel 2, and the plane and any plane where the central axis is located are not coplanar, so that an angle exists between the groove bottom of the avoiding groove 4 and the central axis of the lens barrel 2, namely the angle is set to be an included angle of 15-75 degrees, and preferably 25-45 degrees. And the distance between the groove bottom of the groove 4 and the central axis of the lens barrel 2 is gradually reduced along the direction close to the lens 1, so that an accommodating space for accommodating the rubber needle is formed between the lens 1 and the lens barrel 2, and the rubber needle is convenient to glue.
According to the lens module provided by the embodiment, the avoidance groove 4 is formed in the side wall of the lens barrel 2, so that the glue needle can conveniently extend into the glue groove 3 and glue can be injected, the condition that glue overflows from the surfaces of the lens 1 and the lens barrel 2 is reduced, and the cleanliness and the attractiveness of the lens module are improved; and glue can get into the glue groove 3 completely and be used for the bonding between camera lens 1 and lens cone 2, and the glue solution is sufficient, has strengthened the firm degree of bonding for 1 glue of camera lens is glued later torsion great, has reduced the circumstances that the camera lens 1 squints and runs burnt, the camera lens module is like badly in the in-service use process, thereby has guaranteed imaging quality.
In order to facilitate rapid glue injection, the number of the avoiding grooves 4 is two, and the two avoiding grooves 4 are respectively arranged on two opposite sides of the lens cone 2. Because the outward appearance of lens cone 2 is the structure of square or cylinder usually, the direction is difficult discernment on the naked eye, and through seting up one respectively and dodging groove 4 in the just right position department in the both sides of lens cone 2, can also play the effect of direction discernment in the installation, form the sign in a direction, prevent that the wrong condition from appearing in the installation direction.
As shown in fig. 1-2, the lens 1 includes a lens body 11 and a cap 12, the lens body 11 is a cylindrical structure, the cap 12 is disposed on the lens body 11 for mounting the lens body 11 on the lens barrel 2, and the lens body 11 and the cap 12 are an integrally formed structure. The cross-sectional area of the screw cap 12 is larger than that of the lens body 11, the screw cap and the lens barrel 2 are arranged at intervals, and one end of the lens barrel 2 connected with the lens 1 is covered, so that the space between the screw cap 12 and the lens barrel 2 is too small, and if the avoiding groove 4 is not formed, a glue needle is not easy to stretch into the gap between the screw cap 12 and the lens barrel 2, and glue is injected into the glue groove 3. In order to facilitate manual operation, a plurality of grooves 13 are formed in the edge of the screw cap 12, and the plurality of grooves 13 are uniformly formed in the circumferential direction of the screw cap 12, so that when an operator installs and detaches the screw cap, the friction force generated during screwing and loosening is increased, and the maintenance is facilitated. In order to further improve the convenience of operation, set up the tank bottom of recess 13 into arc structure, prevent that operating personnel from appearing the condition of fish tail when the operation, and arc structure still has the aesthetic property.
The lens barrel 2 includes a lens barrel base 21 and a lens barrel body 22 which are integrally formed, the lens barrel body 22 is an annular structure, the lens barrel body 22 is disposed on the top surface of the lens barrel base 21, the glue groove 3 is formed between the lens barrel body 22 and the lens body 11, and the avoiding groove 4 is specifically disposed on the lens barrel base 21. The avoiding groove 4 is designed by cutting out an inclined plane after removing part of the structure of the lens cone body 22 protruding above the glue groove 3, the part protruding above the glue groove 3 is cut out to enlarge the gap between the screw cap 12 and the lens cone body 22, and the inclined plane is designed to enable the glue needle to be closer to the glue groove 3 so as to reduce the problem of glue overflow. In order to realize the connection between the lens barrel base 21 and the lens body 11, a through hole 23 is provided in the center of the lens barrel base 21, and the lens body 11 is inserted into the through hole 23 and screwed to the lens barrel base 21. Through setting up camera lens body 11 and lens cone base 21 threaded connection to glue to the gluey inslot 3 that forms between the two, improved the less problem of torsion of camera lens 1 in manufacturing process, strengthen the structural stability between camera lens 1 and the lens cone 2.
In order to further strengthen the torsion of the lens 1, the arrangement of the avoiding groove 4 does not completely cut the lens cone base 21, but a chamfer is processed on the side wall of the lens cone base 22, and the lens cone body 22 is cut in the direction of the central axis from the outside, so that the groove bottom of the avoiding groove 4 is positioned on the lens cone base 21, two side walls of the avoiding groove 4 are composed of the lens cone body 22, and when the production and processing are convenient, the groove bottom of the avoiding groove 4 is inclined relative to the horizontal plane, the design is adopted, the number of thread turns between the lens 1 and the lens cone 2 is not reduced, so that the torsion during the assembly of the lens 1 can not be reduced, and the stability and the reliability of the whole structure are ensured.
In order to reduce the situation of glue overflow, the end face of the lens barrel body 22 is higher than the end face of the lens barrel base 21, when the glue injection amount is large, glue used for accommodating overflow is arranged between the end face of the lens barrel body 22 and the end face of the lens barrel base 21, the lens barrel body 22 is designed in a step shape, the lens barrel base 21 does not form a space for accommodating glue, the end face of the lens barrel body 22 can play a role in limiting and blocking glue, the overflow to the side wall of the lens barrel 2 is prevented from being reduced, and the cleanness and the attractiveness of the appearance are increased.
