[embodiment]
Please refer to Fig. 1 and shown in Figure 7, in the method better embodiment of quickly detecting defect of lens of the present invention, provide a data processing equipment 10, an image capture unit 20, a vacuum WAND 30 and a supporting part 40.The method of described quickly detecting defect of lens is used for the defective of automatic gauging eyeglass 50, and this eyeglass 50 comprises an optic 500 and a pedestal 502, and optic 500 is positioned at the middle part of pedestal 502, and it is sphere or aspheric surface.
See also Fig. 2 to Fig. 6, described eyeglass 50 is placed on the supporting part 40, in the present embodiment, this supporting part 40 is a load plate, this supporting part 40 is a thin plate, offers a plurality of containing holes 42 on it, and these a plurality of containing holes 42 are used for ccontaining and fixing eyeglass 50, it is arranged in supporting part 40 according to certain rules, and data processing equipment 10 position that can write down each containing hole 42 by coordinate or other form.This containing hole 42 is a step-like through hole, comprises the holding part 420 and the logical light portion 422 of coaxial setting, and diameter that should logical light portion 422 is less than the diameter of this holding part 420, and forms step at both joining places.The diameter of this logical light portion 422 is suitable with the diameter of eyeglass 50 optic 500, the outside diameter of the diameter of this holding part 420 and eyeglass 50 pedestals 502 is suitable, when eyeglass 50 is positioned over this containing hole 42, pedestal 502 is positioned at holding part 420, optic 500 can see through logical light portion 422 to be exposed, so that eyeglass 50 is tested.Logical light portion 422 also can be a horn-like circular hole, and promptly its diameter that is connected the diameter of an end and eyeglass 50 optic 500 with holding part 420 is suitable, and other end diameter is bigger than normal.
Described data processing equipment 10 is a computing machine in this better embodiment, but its internal processes recognition image information, thereby and to relevant data handle output the result.
Vacuum WAND 30 is electrically connected with data processing equipment 10, and it matches with eyeglass 50 sizes, and can be according to the data absorption eyeglass 50 of data processing equipment 10 indications; And inhale pen 30 and be installed on the support 22 of supporting part 40 opposite sides, rotation, lifting or telescope support 22 in the horizontal direction can make and inhale pen 30 and be positioned at supporting part 40 tops, and can adsorb all eyeglasses 50 on the supporting part 40.
The method of quick test eyeglass 50 defectives comprises the steps: that the surface that supporting part 40 is had logical light portion 422 is placed on the platform downwards, a plurality of eyeglasses 50 are placed on respectively in a plurality of containing holes 42 of this supporting part 40, at this moment, the pedestal 502 of eyeglass 50 is positioned at the holding part 420 of supporting part 40 containing holes 42, optic 500 is positioned at the logical light portion 422 of supporting part 40 containing holes 42, and the logical light portion 422 that the optic 500 of eyeglass 50 sees through this supporting part 40 exposes; Again image capture unit 20 and suction pen 30 are electrically connected with data processing equipment 10 respectively.
Corresponding program and image capture unit 20 in the service data treating apparatus 10, image capture unit 20 transferred to eyeglass 50 bottoms to focal plane 24, slowly upwards fine setting again, eyeglass 50 on 20 pairs of supporting parts 40 of image capture unit is similar to carries out tomoscan, runing rest 22 is so that all eyeglasses 50 on the image capture unit 20 scanning supporting parts 40 simultaneously; Image capture unit 20 is sent to data processing equipment 10 with the image that is scanned simultaneously, if the eyeglass zero defect, data processing equipment 10 can demonstrate the even image of eyeglass 50; If defectiveness in the eyeglass 50, can demonstrate scratch or stain 504 in shown eyeglass 50 images of data processing equipment 10, and the position of writing down this defectiveness eyeglass 50.After detection finishes, start vacuum WAND 30, and make its defective eyeglass 50 positional informations remove defective eyeglass 50 according to record in the data processing equipment 10.
Be appreciated that, in the process of described quickly detecting defect of lens, during data processing equipment 10 scan mirror 50, also can make data processing equipment 10 be fixed on a certain position, and supporting part 40 is placed on the moveable platform, supporting part 40 can be respectively slowly moves on vertical direction and horizontal direction, thereby makes image capture unit 20 can scan all eyeglasses 50 on the supporting part 40.In addition, image capture unit 20 also can be scanned up to the bottom from eyeglass 50 tops.Obviously, be not limited to use vacuum WAND 30 that eyeglass 50 is removed, can use other to remove device.
The method of described quickly detecting defect of lens utilizes optical microscope to combine with image sensor, by the method for similar tomoscan, can find the position of defectiveness eyeglass 50 fast, thereby shortens the time of eyeglass 50 checks, and accuracy is higher.
