Abstract
A detection method for a lens comprises the following steps of: providing a processing platform; arranging a rotating device on the processing platform; arranging a mold core on the rotating device and enabling a lens on a forming surface of the mold core to be contacted with a turning tool; providing a high-magnification microscope; adjusting a fine adjustment of the high-magnification microscope until a sharp image of the lens on the forming surface can be observed; setting a processing parameter for the processing platform and starting the rotating device to enable the lens on the forming surface of the mold core to rotate and enabling the turning tool to grind the lens; and in the rotating process of the rotating device, if no defects in the lens on the forming surface are observed, continuously processing another lens according to processing parameters.
Description
Technical field
The present invention relates to a kind of eyeglass detection method.
Background technology
Along with the development of science and technology, camera is pressed close to daily life day by day.Camera generally comprises camera lens module and image sensing module.The light that passes camera lens module is incident to image sensing module, thereby forms image.The image quality of camera lens module directly affects the image quality of camera.In the manufacture process of camera lens module, the good and bad optical results that is mainly gone out by reciprocal effect between each eyeglass in the camera lens module of camera lens module image quality decides.And eyeglass mainly adopts ejection formation or method of squeeze forming to make.Whether the eyeglass of moulding exists defective directly to affect the quality of transfer printing eyeglass out.Common eyeglass detection method generally is that human eye is directly observed the die face.
Yet some defective (for example lines of tiny tool marks formation) human eye can't distinguish, directly the quality of image molded lenses.
Summary of the invention
In view of this, be necessary to provide comparatively accurately eyeglass detection method of a kind of detection.
A kind of eyeglass detection method, it may further comprise the steps:
One machine table is provided, and this machine table is provided with a wheelwork, will be arranged on the wheelwork for the die of molded lenses and the eyeglass on the die forming surface contacts with lathe tool;
Provide a multiplying power microscope, and this die forming surface is towards these microscopical object lens;
Regulate the burnt spiral of this microscopical thick standard, with the distance between these object lens of coarse adjustment and this die forming surface, until can observe the fuzzy image of the eyeglass on this forming surface;
Regulate the burnt spiral of this microscopical thin standard, with the distance between these object lens of fine tuning and this die forming surface, until can observe the sharp image of the eyeglass on this forming surface;
For machine table is set a machined parameters, start wheelwork, so that the eyeglass on the die forming surface rotates, lathe tool is ground, so that the eyeglass moulding on the die forming surface to eyeglass;
In the process that wheelwork rotates, there is lines in molded lenses on this forming surface if observe, and resets another machined parameters;
There is not regular lines in molded lenses on this forming surface if observe, and continues another eyeglass of processing according to this machined parameters.
Compared with prior art, the eyeglass detection method that embodiment of the present invention provides is detected as the regular lines of molded lenses existence on the profile by the high magnification microscope, so that the not detectable defective of human eye can be found out rapidly, and then help to improve the quality of eyeglass.
Description of drawings
Fig. 1 is the process flow diagram of the die forming surface detection method that provides of embodiment of the present invention.
Embodiment
See also Fig. 1, the eyeglass detection method that better embodiment of the present invention provides may further comprise the steps:
One machine table is provided, and this machine table is provided with a wheelwork, will be arranged on the wheelwork for the die of molded lenses and the eyeglass on the die forming surface contacts with lathe tool;
It is 300 high magnification microscope that one multiplying power is provided, and the eyeglass on this die forming surface is towards these microscopical object lens;
Regulate the burnt spiral of this microscopical thick standard, with the distance between these object lens of coarse adjustment and this die forming surface, until can observe the fuzzy image of the eyeglass on this forming surface;
Regulate the burnt spiral of this microscopical thin standard, with the distance between these object lens of fine tuning and this die forming surface, until can observe the sharp image of the eyeglass on this forming surface;
For machine table is set a machined parameters, start wheelwork, so that the eyeglass on the die forming surface rotates, lathe tool is ground, so that the eyeglass moulding on the die forming surface to eyeglass;
In the process that moving wheelwork rotates, if there is regular lines in the molded lenses of observing on this forming surface, then reset another machined parameters;
There is not regular lines in molded lenses on this forming surface if observe, and continues another eyeglass of processing according to this machined parameters.
Need to prove, the high magnification microscope among the present invention refers to multiplying power and is greater than or equal to 300 microscope, for example, and 400,500,600,700 or higher multiplying power, and machined parameters comprises the rotating speed that moving device rotates etc.The lines of described regularity is circular.
In the present embodiment, observe by this microscopical eyepiece whether molded lenses exists regular lines on this forming surface by human eye.
Certainly, this microscope can also connect a display (not shown).This microscope passes to this display with the image information of this die forming surface, so that observe.
The eyeglass detection method that embodiment of the present invention provides equals or is higher than 300 microscope to be detected as whether molded lenses exists regular lines on the profile by multiplying power, so that the not detectable defective of human eye can be found out rapidly, and then help to improve the quality of molded lenses.
In addition, those skilled in the art also can do other and change in spirit of the present invention, the variation that these are done according to spirit of the present invention, all should be included in the present invention's scope required for protection in.
