Description
Technical field
The present invention relates to a kind of eyeglass pick-up unit, relate in particular to a kind of glasses lens partiality testing apparatus and rotation platform thereof.
Background technology
Along with development of multimedia technology, digital camera, video camera and the mobile phone that has a camera are favored by consumers in general more and more, when the quality of image of people's logarithmic code camera, video camera and mobile phone cam shot object proposed requirements at the higher level, logarithmic code camera, video camera and the product consumptions such as mobile phone that have a camera were also increasing.In the first-class camera of digital camera, video camera and cell-phone camera, camera lens is indispensable parts.
Eyeglass is as the vitals in the camera lens, and the image quality of whole camera lens is played critical effect.Eyeglass is after moulding, grinding and polishing, and its optical axis tends to depart from its geometrical central axis, and this phenomenon is called off-centre.The off-centre of eyeglass can be divided into two kinds in theory, and a kind of is the parallel translation with geometric center of optical axis, and another kind is that optical axis intersects with the eyeglass geometric center, and the in fact normally combination of these two kinds of off-centre of the off-centre of eyeglass.
Traditional eccentricity of glasses lens detection method has multiple, wherein a kind of eccentricity of glasses lens detection method is that eyeglass is fixed on the rotation platform by tweezers etc., an eccentricity detecting device is set above described rotation platform, rotates described rotation platform by finger during detection.The shortcoming of described eccentricity of glasses lens detection method is that rotating rotation platform by finger application of force inequality often occurs, and the central shaft of rotatable platform and eyeglass often change occurs because of rotation, causes measurement result more inaccurate.
Summary of the invention
In view of this, be necessary to provide a kind of and can improve glasses lens partiality testing apparatus and the rotation platform thereof that eccentricity of glasses lens measures accuracy.
A kind of glasses lens partiality testing apparatus, it comprises: an eccentricity of glasses lens detecting device, a rotation platform and a drive mechanism.Described eccentricity of glasses lens detecting device is positioned at the top of rotation platform, described rotation platform is used to place eyeglass to be detected, described drive mechanism is used for the driven rotary platform and rotates, and described rotation platform edge has dentalation, and described rotation platform is by described dentalation and drive mechanism engagement.
A kind of eccentricity of glasses lens detects the rotation platform of usefulness, and described rotation platform is used to place eyeglass to be detected, and described rotation platform edge has dentalation, can mesh with a drive mechanism by described dentalation, rotates to drive described rotation platform.
The rotation platform edge that described glasses lens partiality testing apparatus uses has dentalation, this rotation platform is when carrying out the eccentricity of glasses lens detection, the drive mechanism driven rotary platform that has the structure that meshes with described dentalation by employing rotates, can avoid change occurring because of application of force inequality causes the central shaft of rotatable platform and eyeglass, thus the accuracy that can improve the eccentricity of glasses lens measurement result.
Description of drawings
Fig. 1 is the glasses lens partiality testing apparatus synoptic diagram that the embodiment of the invention provides.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See also Fig. 1, be the glasses lens partiality testing apparatus 100 that the embodiment of the invention provides, it comprises an eccentricity of glasses lens detecting device 10, a rotation platform 20 and a drive mechanism 30.Described eccentricity of glasses lens detecting device 10 is positioned at the top of rotation platform 20, and described drive mechanism 30 is used for driven rotary platform 20 and rotates.
Described eccentricity of glasses lens detecting device 10 is used for the eyeglass 40 that is on the rotation platform 20 is done eccentricity detecting, and it can comprise further that a display screen is used to show eyeglass eccentricity detecting result.By the eccentricity of glasses lens testing result that display screen shows, can judge whether in allowed limits eccentricity of glasses lens.The detection method that common eccentricity of glasses lens detecting device 10 adopts is to utilize the reticle in the collimator to project cross curve, through object lens focusing to eyeglass to be measured 40 first curvature centers, observe the cross curve that reflects by the autocollimator eyepiece again, if first curvature misalignment turning axle, then observed cross curve can be around certain center rotation.Rotate eyeglass and adjust rotation platform 20 and make cross curve in the fixed position this moment, again with the torsion center of object lens focusing to eyeglass 40 to be measured, the cross curve that reflect this moment can be around the circle rotation of certain radius, and this radius of turn can obtain glasses lens eccentricity after how much conversions.
Described rotation platform 20 is used for placing eyeglass 40 when eccentricity of glasses lens detects, it can rotate along self central shaft.In the present embodiment, described rotation platform 20 central authorities are provided with a groove 21 and are used to put eyeglass 40, and preferably, the shape of described groove 21 is identical with the shape of eyeglass 40, the sizableness of the size of groove 21 and eyeglass 40.For making things convenient for rotation platform 20 to cooperate with drive mechanism 30, described rotation platform 20 edges have the structure with drive mechanism 30 engagements, as dentalation 22.
Described drive mechanism 30 be can with the mechanism of described rotation platform 20 engagements, it specifically can be gear mechanism, worm mechanism or rack mechanism.Described drive mechanism 30 can be formed face gear mechanism or space gear mechanism jointly with rotation platform 20, described face gear mechanism is meant motion and the power that transmits between two-parallel axis, and the space gear mechanism is meant motion or the power that transmits between two space intersection axles or alternating axis.In the present embodiment, described drive mechanism 30 can be formed face gear mechanism jointly with rotation platform 20, and described drive mechanism 30 is a cylindric gear.
For ease of adjusting the relative position between eccentricity of glasses lens detecting device 10 and the rotation platform 20, in eccentricity of glasses lens detecting device 10 and the rotation platform 20 at least one can be connected in one can be along in the mechanism that the X-Y direction of principal axis moves.In present embodiment, but can together move with drive mechanism 30 along the control platform 50 driven rotary platforms 20 that the X-Y direction of principal axis moves by one.
The rotation platform edge that described glasses lens partiality testing apparatus uses has dentalation, this rotation platform is when carrying out the eccentricity of glasses lens detection, the drive mechanism driven rotary platform that has the structure that meshes with described dentalation by employing rotates, can avoid change occurring because of application of force inequality causes the central shaft of rotatable platform and eyeglass, thus the accuracy that can improve the eccentricity of glasses lens measurement result.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
