Description
Technical field
The utility model is related to a kind of lossless perspective detectors of cam lens, belong to camera structure detection technique neck
Domain.
Background technology
Camera has the tolerance of lens strict requirements, the optical axis of lens is inclined as a kind of high-precision optical product
Angle, radial deflection and axial gap need to carry out accurate adjustment according to optical center thickness.And whether its processing meets essence
Degree requirement, then need high-precision instrument to check and measure it.
Measurement lens thickness technology can be divided into contact and contactless at present, contact measurement method there are the shortcomings that
It is easily camera lens to be caused to damage；Non-contact measurement will not cause to damage to camera lens, exist in the prior art a kind of using altogether
For focus optical system to measure the method for lens thickness, it is the different positions that incident polychromatic light is focused to optical axis by wavelength to act on
Place is put, while generates axial chromatic aberration.The focus of measurement range, that is, minimal wave length and most the distance between long wavelength's focus.This method
The multiple maximum for moving to find measurement thickness on lens by lens holder is needed, to lens centre point location efficiency very
It is low.
Utility model content
The purpose of this utility model is to provide a kind of lossless perspective detector of cam lens, concrete scheme is：

Confocal optics are popped one's head in, and optic probe 3 is set towards underface, and optic probe 3 is moved up by servomotor drives edge two-dimensional movement frame
It is dynamic；3 lower section of optic probe is equipped with lens holder 4, and lens holder 4 is used to fix lens 5；4 lower section of lens holder is set
There is locating platform 8；The locating platform 8 includes two loop laser emitting heads 7 and an image camera 6.
The image camera 6 is located at the center of locating platform 8, and two loop laser emitting heads 7 are distributed in into angle
The side of image camera 6.
The image camera 6 is CCD camera.
The lens holder 4 is three clamping fixture heads.
The detector of this programme is equipped with locating platform 8, and locating platform is used to quickly position the central point of lens 5,
The detection speed of lens center thickness can be greatly improved.The positioning principle of locating platform is that two loop laser emitting heads 7 are distinguished
Annular laser rays is projected in the lower surface of lens, since lens surface is curved surface, loop laser line is ellipse in lens surface distortion
Round shape laser rays 10, and 5 center of long axis direction face lens of ellipticity laser rays 10, and pass through two ellipticity laser
The crosspoint O of the long axis direction of line 10 can orient the central point of lens 5.When specifically used, CCD camera is to lens surface
Imaging by the image-forming information of computer disposal CCD camera, can quickly orient lens centre point, and computer is according to obtaining
The control servomotor work of lens centre dot position information, the quick optic probe that adjusts is moved to lens centre point.In addition, light
Auxiliary positioning laser head can also be set on the pedestal of probe by learning, to improve positioning accuracy.
