Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a device of quick adjustment camera lens axiality.
[ background of the invention ]
With the rapid development of high and new technologies, the security optical zoom lens is widely applied. In order to meet the market demand, more and more lenses use large chips with high resolution, and zoom lenses are applied to different environments in different fields, so that the design difficulty of the lenses is higher and higher, the technical requirements of each group are higher and higher, the requirements on product forming, process manufacturing and the like are also higher and higher, on the premise of the existing production and manufacturing technology, the requirements at the initial stage of optical design are difficult to realize, the expected production yield cannot be reached, the market demand for high-speed promotion cannot be met, and finally the leaders in the industry cannot be maintained.
The utility model discloses it is based on above problem produces.
[ Utility model ] content
The utility model aims at the not enough of prior art, provide a device of quick adjustment camera lens axiality, through the axiality of adjusting accent core group, realize the axiality of whole camera lens and adjust.
In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a device of quick adjustment camera lens axiality, a serial communication port, including the lens mount, be connected with the back lid on the lens mount, cover the accent core group of connecting to move on its horizontal plane after, accent core group including the picture frame with set up the battery of lens on the picture frame, cover after and seted up the through-hole, be provided with in the through-hole and be used for placing the step of accent core group, the internal diameter of through-hole is greater than the external diameter of picture frame and makes accent core group take place the displacement and then adjust the axiality of battery of lens and other groups on the plane at back lid place.
The device for quickly adjusting the coaxiality of the lens is characterized in that at least two adjusting positions which can be used for placing external equipment and matching with and adjusting the position of the lens frame are arranged on the inner side wall of the through hole and positioned on the rear cover.
The device for quickly adjusting the coaxiality of the lens is characterized in that the number of the adjusting positions is four, and the adjusting positions are distributed on the inner wall of the through hole in an array manner.
Compared with the prior art, the utility model discloses a device of quick adjustment camera lens axiality has following beneficial effect:
1. the utility model discloses can adjust its axiality for other groups through the position of adjusting core group, realize optics specification requirement that promotes day by day, finally realize the optical design performance, compensate not enough of current production and goods technique, can assist the improvement of the optical design degree of difficulty, concentrate on certain design with sensitive item, finally promote the wholeness ability of product design.
2. The core adjusting group of the utility model has simple structure, is convenient for the core adjusting operation of a single lens, consumes little time, can greatly improve the production yield of the machine type and improve the productivity;
3. the utility model discloses avoided removing the axiality between group and the fixed group very poor, kept away from the optics design value, be difficult to realize the optics design target.
[ description of the drawings ]
The following detailed description of embodiments of the present invention is provided with reference to the accompanying drawings, in which:
fig. 1 is a perspective view of the present invention;
fig. 2 is a cross-sectional view of the present invention.
[ detailed description ] embodiments
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 and fig. 2, in the present embodiment, a device for rapidly adjusting the coaxiality of a lens includes a lens holder 1, a back cover 2 is connected to the lens holder 1, a core adjusting group 3 capable of moving on a horizontal plane of the back cover 2 is connected to the back cover 2, the core adjusting group 3 includes a lens frame 31 and a lens set 32 disposed on the lens frame 31, a through hole 21 is formed in the back cover 2, a step 22 for placing the core adjusting group 3 is disposed in the through hole 21, and an inner diameter of the through hole 21 is larger than an outer diameter of the lens frame 31 so that the core adjusting group 3 displaces on a plane where the back cover 2 is located to adjust the coaxiality of the lens set 32 and other groups; in this embodiment, the distance between the internal diameter of through-hole and the external diameter of picture frame is 0.1mm for the picture frame can produce the displacement in the through-hole, adjusts the axiality. The utility model discloses can realize optics specification requirement that promotes day by day through adjusting accent core group, finally realize the optical design performance, compensate not enough of current production and goods technique, can assist the improvement of the optical design degree of difficulty, concentrate on certain design with sensitive item, finally promote the wholeness ability of product design.
As shown in fig. 1 and fig. 2, in the present embodiment, at least two adjusting positions 23 for placing external devices and adjusting the positions of the lens frame 31 are disposed on the inner side wall of the through hole 21 of the back cover 2. The position of the lens frame 31 can be adjusted by extending the hand grip to the adjusting position, and after the coaxiality of the lens group relative to other groups is adjusted by external equipment, the core adjusting group is fixed on the rear cover through a connection mode of dispensing to form a fixed group.
As shown in fig. 1 and fig. 2, in the present embodiment, the number of the adjusting positions 23 is four, and the adjusting positions are distributed on the inner wall of the through hole 21 in an array.
