Embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.

See also the utility model the 1st, 2 figure, testing fixture 1 for optical lens 2 of the present utility model, be to check out optics eyeglass 2, whether have defectives such as bubble, scratch, external form profile, dirty, foreign matter, testing fixture 1 its design concept of the present utility model is to comprise: can place, check and take out fast fast optical glasses eyeglass 2 to be measured fast; And designing a kind of light source mode, it can be effectively and conveniently solves the following condition that influences defective obviousization: eyeglass curvature, lens thickness, colour of lens, glasses lens plated, curved surface outside meeting are reflected light and be can't see inner face.Testing fixture 1 of the present utility model is to mainly include: optical glass unit 11, the ring-like smooth unit 13 of low angle and taking unit 15, explanation as back are interior civilian respectively now.

Optical glass unit 11 is to cover on the ring-like smooth unit 13 of low angle, and the optical lens 2 that is used for bearing examine (survey).The testing staff is placed on the optical lens 2 of examine the middle section position of the upper surface of optical glass unit 11, optical lens 2 its tops that place are the camera lens 151 that faces taking unit 15, and optical lens 2 its belows are the middle section position that faces the ring-like smooth unit 13 of low angle.Optical glass unit 11 practicable known optical glass sheets.

The function of the ring-like smooth unit 13 of low angle provides the low angle ring-shaped light source, and the light that described low angle ring-shaped light source is launched, can pass through optical glass unit 11 and optical lens 2, and the optical lens 2 of full wafer can be arrived all by the light of described low angle ring-shaped light source institute uniform irradiation.The ring-like smooth unit 13 of low angle is arranged on the below of optical glass unit 11.The ring-like optical assembly of the ring-like smooth unit 13 practicable known low angles of low angle is for example carried out the ring-like blue light component of known low angle.

The function of taking unit 15 is to optical lens 2 capture of taking pictures.Taking unit 15 and even include GTG CCD photosensory assembly less or the colored CCD photosensory assembly, or, taking unit 15 and even include GTG CMOS photosensory assembly less or the color cmos photosensory assembly.The concrete device for carrying out said of taking unit 15 for example is to adopt digital camera or digital camera.

See also the 3rd figure, taking unit 15 is further to connect image processing apparatus 3, and the concrete example of image processing apparatus 3 for example is a computing machine.15 pairs of optical lens 2 of taking unit are taken pictures after the capture, be can output corresponding to the optical lens digital image data 15a of optical lens 2, and image processing apparatus 3 initiatively receives optical lens digital image data 15a.Then, image processing apparatus 3 carries out image comparison and handles according to optical lens digital image data 15a, and is last, and image processing apparatus 3 determines to judge whether the optical lens 2 that detects at present exists above-mentioned defective.

Please cooperate referring to the utility model the 1st, 2 figure, moreover testing fixture 1 of the present utility model is further to comprise: support body 17 and displacement unit 19.The function of support body 17 is that displacement unit 19, the ring-like smooth unit 13 of low angle and optical glass unit 11 are set.Support body 17 is to include: upright cylinder 171 and platform 173.The ring-like smooth unit 13 of low angle is to lie on the platform 173, and then, optical glass unit 11 covers on the ring-like smooth unit 13 of low angle.One end end of cylinder 171 is to be fixed on platform 173, and displacement unit 19 be movable be retained on cylinder 171.Displacement unit 19 is to move taking unit 19 for fixing and displacement.Taking unit 19 can carry out big portion earlier by displacement unit 19 and adjust the Z axle, and then thin portion adjusts the Z axle, and then, thin portion adjusts X-axis again, so makes taking unit 19 be adjusted to the take pictures position of capture of the best.

Testing fixture 1 of the present utility model is except possessing quick placement, check fast and taking out fast the advantages such as optical glasses eyeglass to be measured, and design the ring-like smooth unit 13 of low angle as the utility model light source means, it can be effectively and conveniently solves the condition that influences obviousization of defective, and the utility model possesses the advantage that remarkable efficacy is promoted.
