One side, the through hole and thang-kng groove are arranged on the another side of sample disc.
Further, the lens hole is arranged in sample disc in the form of multiple lines and multiple rows, and a plurality of thang-kng groove passes through multirow
The through hole of lens hole.
Further, the aperture dimension of the bellmouth orifice is depending on effective clear aperture of non-spherical lens.
Further, the size of the bellmouth orifice isTaper is 90-130 °.
Further, the taper of the bellmouth orifice is 100-120 °.
Further, the through hole internal diameter is slightly larger than the external diameter of non-spherical lens.
Further, the width of the thang-kng groove is 3-4mm.
Further, it is provided with pin hole in the sample disc.
Further, described two sample discs coordinate the detection for non-spherical lens two-by-two.
Further, the sample disc is made of red copper material.
The beneficial effects of the utility model are：Accurate effective clear aperture is provided with detection means, can be accurate
The defects of effective clear aperture of control lens, as long as can let off the defects of outside effective clear aperture, it is qualified to be considered as；Can
More detections of single, and 7 are completed from original artificial single detection of single is per minute, now per minute to complete 22, detection
Efficiency is improved more than 3 times；Originally 100 lens of desk checking, there is missing inspection, cross inspection 5-13, using of the present utility model
After mirror detection means, missing inspection, excessively inspection rate are 0%, and the yields of product is improved into 5-10% or so；Can be directly by glass lens
Fixed inspection in sample disc is placed, the landing occurred in two-sided inspection is avoided, causes the generation of secondary defect.

Embodiment
As Figure 1-5, optical glass non-spherical surface lens detection means of the present utility model includes sample disc 1, in sample
Lens hole 3 and thang-kng groove 4 are provided with disk 1.The lens hole 3 includes bellmouth orifice 5 and the two parts of through hole 6, the bellmouth orifice 5 to
Lower extension forms through hole 6.Wherein, bellmouth orifice 5 is arranged on the one side of sample disc 1, internal aperture (effective light hole) size according to
Depending on effective clear aperture of non-spherical lens, conventional size isThe taper of bellmouth orifice 5 is usually 90-130 °,
Wherein 100-120 ° is best angle, preferably can be carried out the aspheric component of lens spacing.Through hole 6 and thang-kng groove 4 are set
The another side in sample disc 1 is put, planar section progress spacing and light of the through hole 6 to non-spherical lens is saturating, and its internal diameter is slightly larger than non-
The external diameter of spherical lens, stock size areThe width of thang-kng groove 4 is usually 2-6mm, most preferably 3-4mm.Thang-kng groove
4 are arranged on the underface of lens hole 3.
In order to improve the operating efficiency of detection, above-mentioned lens hole 3 is arranged in the form of multiple lines and multiple rows in sample disc 1, more
Bar thang-kng groove 4 passes through the through hole 6 of multirow lens hole 3, as shown in Fig. 2,5.
Pin hole 2 is additionally provided with sample disc 1, is easy to the fixation of two sample discs 1.Two sample discs 1 coordinate two-by-two
Detection for non-spherical lens.
Above-mentioned sample disc 1 is made preferably with red copper material, and its length and width size can be according to the placement stroke dimension of manipulator
Depending on.
During work, non-spherical lens is loaded into corresponding to sample disc 1 on lens hole 3, it is whole to treat that non-spherical lens fills one
After disk, by another left-hand thread of sample disc 1 to non-spherical lens it is aspherical on, as shown in fig. 6, or left-hand thread to non-spherical lens
In plane, as shown in fig. 7, can be spacing to all non-spherical lens progress, then pin hole 2 is passed through by two pieces of samples with pin
Disk 1 is fixedly connected.The sample disc 1 fixed is placed on clean bench, projector beats light beam in aspheric through thang-kng groove 4
On the lens of face, you can carry out non-spherical lens outward appearance detection.
Lens are detected using non-spherical lens detection means of the present utility model, because it devises porous eyeglass position
And its fixing means, and effective clear aperture and thang-kng groove 4 are devised, therefore more detections of single can be not only completed, improve
Checkability, and can be by effective clear aperture accurate judgement glass defect where, substantially increase inspection
Accuracy.In addition, because of its cleverly fixing means, two-sided detection can be directly carried out after fixing, it is no longer necessary to which movement is non-
Spherical lens, after simultaneously having detected, turn over one side can and another side detected, thus simultaneously complete two-sided detection and
More detections of single, it is possible to prevente effectively from the landing that lens occur in two-sided detection causes the generation of secondary defect, are improved
The yields of product.
