In a specific implementation process, the shape of the base may be annular, cubic, or the outer side is cubic and the inner side is annular, and the shape of the base is not limited in the present application, and is not an example. Through holes 102 are formed in the side wall 101 of the base, and in a specific embodiment, the through holes 102 may be formed at different positions of the side wall 101 of the base according to actual requirements. For example, for an annular base applied to a camera module, the through hole 102 may be disposed at a middle position of the base sidewall 101 along the central axis direction, and certainly may also be disposed at an upper end position or a lower end position along the central axis direction. In addition, the present embodiment exemplarily shows that one through hole 102 is provided in the base sidewall 101, but it should be understood that a person skilled in the art may provide a plurality of through holes 102 according to practical situations, for example, one through hole 102 is provided at each of two opposite positions of the base sidewall 101, and the present application does not limit the number of the through holes 102.
An accommodating area 103 is arranged in an area, communicated with the through hole 102, on the inner wall of the base, the accommodating area 103 is provided with a first preset width 104 along the central axis direction of the base and a second preset width 105 in the direction perpendicular to the central axis, so that a groove-shaped accommodating area 103 can be formed to accommodate the adhesion substances. In a specific implementation process, the adhesion substance may be UV (Ultra-violet) glue, AB glue (two-liquid mixed hardened glue), low-temperature cured single-component epoxy glue, etc., and the selection of the adhesion substance also differs according to the difference of the components of the base assembly, for example, UV glue may be used for fixing the camera and the base, and low-temperature cured single-component epoxy glue may be used when fixing the base and the FPCB (Flexible Printed Circuit Board). In addition, the adhesive substance is pressed into the receiving section 103 from the through-hole 102 by the adhesive substance injector, which requires that the diameter of the through-hole 102 must be larger than the diameter of the adhesive substance injector so that the adhesive substance can smoothly enter the receiving section 103.

the receiving area 302 is used for receiving the adhesive substance injected from the through hole 301 to fix the base 300 and the lens 310 assembled with the base 300.
In a specific implementation process, the inner wall of the base 300 and the outer wall of the lens 310 are provided with threads, and after the base 300 and the lens 310 are assembled together through the threads, the assembling parts also need to be fixed, and in an actual implementation process, the assembling parts can be adhered together by using glue. However, in a specific practice process, the inventor of the present application finds that the lens is scrapped due to the fact that the lens is easily dispensed onto the lens of the camera module by using the current dispensing method, because the dispensing equipment is operated for a long time, the positioning precision is reduced, and the dispensing equipment cannot be accurately positioned to the gap between the lens and the base, so that the dispensing error is caused, and the problem can be solved by additionally purchasing dispensing machines and enabling the dispensing machines to operate in turn. However, with this method, on one hand, the equipment investment cost is increased, and on the other hand, if the time is long, the positioning accuracy is still reduced, and the fundamental technical problem cannot be solved in the long run. Therefore, the inventor of the present application sets forth the technical solution disclosed in the present application starting from the structure of the camera module itself, that is, a through hole 301 is formed in the side wall of the base of the camera module, the through hole 301 is communicated with the inner wall of the base, an annular or spiral accommodating area 302 is formed in the communication area, and the glue dispensing device injects glue into the accommodating area 302 through the through hole to fix the base and the lens. Therefore, the lens area is avoided, so that the glue can not contact the lens completely in the dispensing process, the condition that the lens is scrapped due to lens adhesion is avoided, and the production yield of the camera module is improved.
In a third aspect, there is provided a bonding material injector, as shown in fig. 4, having a needle hole 401, wherein the needle hole 401 injects the bonding material into the receiving area through the through hole of any one of the first aspect, and wherein the diameter of the needle hole 401 is smaller than that of the through hole. In the specific implementation process, can through the mode of artifical point gluing or adopt the automatic point gluing of some adhesive equipments, no matter which kind of mode of adoption, all include the bonding material injector, the bonding material injector is including storing up gluey part and some glue parts, and some glue parts have pinhole 401, and the diameter of this pinhole must be less than the diameter of through-hole to make glue can pass through the through-hole of base lateral wall and impress the holding district of base inner wall. In addition, for the dispensing apparatus, since the dispensing position is changed from the upper side of the lens to the side of the base, the operation procedure of the dispensing apparatus is modified to adjust the dispensing direction of the dispensing pin hole.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
because the through hole is formed in the side wall of the base, and the accommodating area is formed in the inner wall of the base, when the assembly part is fixed, the bonding material can enter the accommodating area in the base through the through hole in the side wall, so that the situation that the bonding material is possibly adhered to the base due to the fact that the bonding material is injected into the key part of the assembly part is avoided, and the production and manufacturing yield is improved.
