Abstract
The utility model relates to a lens cone and base assembling structure for use in a digital lens module. The utility model is characterized in that an annular groove is arranged on the outer edge of a lens cone; a rubber ring is arranged in the annular groove; the outer diameter of the rubber ring is bigger than that of the lens cone under the installation state; the front end of a base is provided with a connecting sleeve barrel; the inner edge of the sleeve barrel is a smooth inner surface. When the utility model is assembled, the lens cone is put in the sleeve barrel of the base, and the rubber ring on the outer edge of the lens cone is in contact with the inner edge of the sleeve barrel; thus, a lens is positioned in the sleeve barrel at the front end of the base. The assembling structure of connecting an inner screw thread and an outer screw thread is changed to the connecting structure of the silicon rubber ring. The utility model has the advantages of simple structure and artificial design, and also has the advantages that the focus and the rotary angle of the adjusted lens are not influenced; the utility model is favorable for autoimmunization assemblage and measurement; the utility model is favorable for absorbing the vibration to improve the anti-vibration performance, and the utility model overcomes the defect that bad image is formed caused by the chipping because of the friction of the screw thread.
Description
Technical field
The utility model relates to a kind of digital type photograph/pick-up lens module that uses on the electronic installations such as mobile phone, PC, notebook computer and digital camera, is specifically related to lens barrel in this module and a kind of assembly structure between the pedestal.
Background technology
Along with the development of digital imaging technique, the application of digital photographing/camera function is increasingly extensive, and wherein relatively the typical case directly applies on mobile phone, PC and the notebook computer this function as one of important subsidiary function.At technical elements, key component with digital photographing/camera function is a digital mirror head mould group, this module normal open is made of camera lens (lens), pedestal (holder) and CMOS image sensor [complementarity matal-oxide semiconductor image sensor (Complementary Metal-Oxide Semiconductor)], camera lens is connected with the CMOS image sensor by pedestal, converts light signal to data image signal.Chinese patent discloses a name on September 29th, 2004 and has been called " Digital photographic thermomechanical components and apparatus for assembling thereof and method ", and number of patent application is 03178409.7, and publication number is the application for a patent for invention of CN1532571A.Put down in writing the typical structure that lens barrel and pedestal assemble in the at present existing digital mirror head mould group in this patent application document, the outer rim that is lens barrel is provided with external thread, the pedestal front end has a coupling sleeve, the inner edge of sleeve is provided with internal thread, the external thread of lens barrel is screwed into the internal thread of sleeve during assembling, connect with this threaded engagement, the focal length of adjusting between camera lens and the rear CMOS image sensor by the rotation lens barrel is also fixed then.Yet in the practice, it is found that above-mentioned assembly structure has the following disadvantages: 1, owing to camera lens and CMOS image sensor in the batch process there are differences self, transfer the anglec of rotation and the focal length of the relative CMOS image sensor of camera lens in the survey all to influence image effect, adjust focal length when employing is threaded the anglec of rotation is met the demands simultaneously, therefore will seek out desirable image effect is the comparison difficulty; 2, in transferring the survey process, because the relative base socket sleeve of lens barrel comes back rotation, the fricative chip of screw thread drops on CMOS image sensor surface easily, causes image bad, causes repair rate to increase.
Summary of the invention
The utility model provides lens barrel and pedestal assembly structure in a kind of digital mirror head mould group, its objective is in order to improve the acceptance rate of digital mirror head mould group.
For achieving the above object, the technical solution adopted in the utility model is: lens barrel and pedestal assembly structure in a kind of digital mirror head mould group, on the outer rim of lens barrel, ring groove is set, settles rubber ring in the ring groove, the external diameter of rubber figure under installment state greater than the lens barrel external diameter; The pedestal front end has a coupling sleeve, and the sleeve inner edge is a slippery inner surface, and lens barrel places the sleeve of pedestal during assembling, and the rubber ring on the lens barrel outer rim contacts with the sleeve inner edge, with this camera lens is positioned in the sleeve of pedestal front end.
Related content and change interpretation in the technique scheme are as follows:
1, in the such scheme, be to increase the bearing accuracy of camera lens in pedestal front end sleeve, the axial forward and backward setting of lens barrel outer rim is bipassage ring shape groove at least, settles a rubber ring in the per pass ring groove, and camera lens is positioned in the sleeve by twice rubber ring at least.
2, in the such scheme, described rubber ring adopts falope.
The utility model principle of work is: on the camera lens outer rim rubber ring is set, utilizes this rubber ring that camera lens is positioned in the sleeve of pedestal front end, thereby form the assembly structure between camera lens and the pedestal.In transferring the survey process, move axially camera lens and can adjust focal length, rotate the anglec of rotation that camera lens can be adjusted the relative rear of camera lens CMOS image sensor.Transfer behind the geodesic structure camera lens to be fixed with CMOS image sensor relative position and get final product with glue.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, simple in structure, be skillfully constructed.
2, do not influence the focal length and the anglec of rotation of adjusting camera lens, can make the relative CMOS image sensor of camera lens be in the optimum position, performance optimal images effect.
3, the design is suitable for the machine automatic focusing, for realizing in the future the robotization assembling and transferring to survey and lay a good foundation.
4, owing between the sleeve of camera lens and pedestal, be provided with rubber ring, can absorb external vibration, improve the anti-seismic performance of digital mirror head mould group.
5, overcome in the past because the screw thread friction causes the bad influence of image after producing chip.
