Abstract
The utility model relates to a thread assembling structure for a lens cone and a base in a digital lens module. The utility model is characterized in that the back end of the lens cone is provided with a sleeve barrel, an inner screw thread is arranged on the inner edge of the sleeve barrel, the front end of the base is provided with a connecting barrel; an outer screw thread is arranged on the outer edge of the connecting barrel; the inner screw thread on the inner edge of the sleeve barrel is connected with the outer screw thread on the outer edge of the connecting barrel. Thereby, the lens is positioned on the base. The connection relationship between the inner screw thread and the outer screw thread of the existing lens cone and the existing base is exchanged, namely that the inner screw thread is arranged on the lens cone and the outer screw thread is arranged on the base. When the utility model is assembled, the inner screw thread on the lens cone is matched with the outer screw thread on the base. In the processes of measurement and repair, when the lens cone rotates backwards and forwards relative to the connecting barrel of the base, the chipping generated by the friction of the screw threads can not falls on the surface of a CMOS image sensor; thus, the image is good.
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 screw fit 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 the deficiency of above-mentioned assembly structure is: 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 base thread 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, especially overcome and transferring the survey process because the harmful effect that the fricative chip of screw thread brings to the quality of image.
For achieving the above object, the technical solution adopted in the utility model is: lens barrel and base thread assembly structure in a kind of digital mirror head mould group, and the lens barrel rear end is provided with sleeve, on the inner edge of sleeve internal thread is set; The pedestal front end is provided with a connecting cylinder, on the outer rim of connecting cylinder external thread is set; Internal thread on the sleeve inner edge is connected with external thread on the connecting cylinder outer rim, with this camera lens is positioned on the pedestal.
In the such scheme, in order further to control of the influence of the fricative chip of screw thread to CMOS image sensor surface clearness, can in the sleeve of lens barrel, be provided with guard ring, guard ring and sleeve inner edge wall form the ring cavity space, connecting cylinder is arranged in the ring cavity space, and connects by above-mentioned internal and external screw thread.
The utility model principle of work is: the internal and external screw thread annexation between lens barrel in the prior art and the pedestal is exchanged, be about to internal thread and be located on the lens barrel, external thread is located on the pedestal, and the internal thread during assembling on the lens barrel cooperates with external thread on the pedestal.In transferring the survey process, when the relative pedestal connecting cylinder of lens barrel comes back rotation, the fricative chip of screw thread can not drop on the CMOS image sensor surface, causes image bad.If be provided with guard ring in the sleeve of lens barrel, the effect of its protection screw thread friction chip is then better.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, reasonable in design, be skillfully constructed, simple and practical.
2, effectively controlled because screw thread friction generation chip causes the bad influence of image.
