Description
Technical field
The utility model relates to a kind of Light-modulating mirror head unit, especially a kind of lens assembly with an automatic light meter.
Background technology
At present, the camera lens of prior art generally is the aperture of manual adjustments formula, and aperture is ascending to be divided into several gears, and the corresponding f-number of each gear is in use according to the state of light source and the needs of image are set a fixing gear at that time.In actual use, illumination intensity of light source is in the continuous attenuation process, the brightness of the image that ccd video camera is taken the photograph is constantly deepening thereupon also, picture quality constantly descends along with the decay of light illumination, causes differently finely detecting software to the detectability of foreign fiber in the cotton worse and worse.
The utility model content
The utility model can not be regulated along with the decay of light illumination automatically for the lens aperture size that solves the prior art existence, picture quality constantly descends along with the decay of light illumination, video camera provides a kind of lens assembly with an automatic light meter to the recognition capability problem worse and worse of different fibre; Mainly be made up of aperture adjusting electric cabinet and diaphragm mechanism two parts, aperture is regulated electric cabinet and is carried out communication by serial port and host computer.Host computer is according to the image situation that collects, judge whether aperture size is adjusted, when needs dwindle or open large aperture, just regulate electric cabinet by serial port to aperture and send command adapted thereto, aperture is regulated and is made corresponding actions by camera lens converting interface control diaphragm mechanism after electric cabinet receives instruction.
The technical solution of the utility model: be by motor coil 1; Diaphragm motor 2; . control winding displacement 3; Motor gear 4; Diaphragm gear ring 5; Diaphragm body 6; Loam cake 7; Motor gear 8; Diaphragm gear ring 9; Untie-sell hole 10; Diaphragm sheet 11; Rationed marketing groove 12; Rationed marketing 13; Untie-sell 14; Its concrete technical scheme is: earlier diaphragm sheet 11 is installed to above the diaphragm body 6 during installation, installs diaphragm gear ring 5,9 then, loam cake 7 is installed again, diaphragm motor 2 is installed at last; Before diaphragm sheet 11 is installed, earlier will be with rationed marketing groove 12, rationed marketing 13, untie-sell 14 are installed to (12,13,14 erection sequence is any) on the diaphragm sheet 11.Described diaphragm motor 2 comprises: motor coil 1, control winding displacement 3, motor gear 4,8.After the entire mechanism installation, be arranged at the middle part of camera lens.Untie-sell hole 10 is distributed on the diaphragm gear ring 9.Diaphragm sheet 11 is arranged on diaphragm body 6 middle parts, on diaphragm gear ring 9 one sides untie-sell 14 is set, and untie-sell 14 tops are provided with rationed marketing 13, and a side of rationed marketing 13 is provided with rationed marketing groove 12; On diaphragm gear ring 9 another sides diaphragm motor 2 is set, diaphragm motor 2 one sides are provided with motor coil 1, and motor coil 1 outside connects control winding displacement 3.Diaphragm motor 2 tops are provided with motor gear 4, and motor gear 4 belows are provided with gear ring 5, motor gear 8 interlocks that gear ring 5 and diaphragm gear ring 9 tops are provided with, and loam cake 7 is arranged on diaphragm body 6 another sides, constitutes lens assembly with an automatic light meter.
Dynamic duty process of the present utility model: when aperture adjusting electric cabinet control diaphragm dwindles, signal is transferred to the diaphragm motor through the camera lens converting interface, motor gear drives the diaphragm gear ring changes an angle counterclockwise, the diaphragm gear ring drives the diaphragm sheet to the displacement of diaphragm center, thereby reaches the purpose of receiving the little aperture of the diaphragm, stop down.Rotational angle is big more, and then diaphragm shrinks more little.Otherwise, then diaphragm can be opened greatly.
The beneficial effects of the utility model are: the maximum gear that the aperture static stall that the utility model is set normally can reach less than aperture, decay to when not meeting specified technical indicator at light source, be that the brightness of image that photographs of ccd video camera is undesirable, this moment is if can amplify aperture again, then can make the image that photographs meet technical requirement again, thereby can prolong the life cycle of light source.Camera lens is mainly used in and is installed in the ccd video camera front end, can realize regulating automatically the size of lens aperture, be consistent, and not change because of the change of light source with the brightness of guaranteeing the image that ccd video camera photographs, guarantee the quality of image, prolong the life cycle of light source.
