Technical background: with the development of economic and technology, the use of augmented reality ( Augmented Reality, AR) Equipment of people more and more widely, making the AR equipment market booming, but as a result of current AR industry has just started, to the imaging effect of optical lens surface detection method is still in the exploratory stage. Most detection optical surface lens curvature method is by measuring instrument to measure the curvature of the optical surface of the lens, this is indirect measurement, cannot directly detect the imaging effect; The instrument measuring cycle long, the measuring equipment is expensive, for optical lenses, measurement, only scrap processing products, so as a sample, most cannot achieve full inspection of the products. Technical implementation elements: the utility model to solve the technical problem is: to provide an AR optical lens surface detection device, can directly detect the lens imaging effect, short detection time, can realize the full inspection of the product, and the products without damage, does not affect the subsequent use of the lens. In order to solve the technical problems, the technical scheme of the utility model is: AR optical lens surface detection device, including support, described are installed on bracket screens and semi-permeable half mirrors, stents, including lenses can be placed under test is the lens holder, described the vertical setting it is lens bracket on one side of the screen, described a semipermeable grin lens tilt is set in the top of the lens holder, and described respectively with screens and described as acute Angle between the lens bracket. Due to the lens holder for two on relative support units, were placed on both ends of the lens under test in the two support platform, which can effectively reduce the contact area of the lens and lens holder under test, avoid to test lenses have scratches, and convenient take put the lens under test. Due to the upper part has a photo of the lens under test equipment, photo equipment and image analysis instrument connections. Can take pictures of photo equipment for imaging effect, and then import the picture image analyzer, and through the analysis of image analyzer for pictures to judge the imaging effect, the digital imaging effect, objective, and can avoid subjective influence, reach higher testing standards. To sum up, the utility model AR optical surface lens detection device, short detection time, detection effect is good, the optical surface of the lens can be subjective objective full inspection, full inspection and can effectively avoid the bad product outflow and online, the device is simple, portable, and no damage of product and does not affect the subsequent use of the lens. The appended drawings is shown in figure 1 that the utility model is AR optical surface lens detection device of three-dimensional sectional view; Figure 2 is the utility model AR optical lens surface detection device working principle diagram; Figure 1 Bracket, 11 - Support units, 12 - Circular arc, 13 - Floor, 14 - The first support plate, 15 The second support plate, 16 - Mounting plate, 17 - The third support plate, 2 - Display, 3 - A semipermeable half mirrors, 4 - The lens under test, 5 - Photo equipment. Concrete implementation way of combining the appended drawings below and implement this utility model further instructions. In the instruction manual, close to one side of the center of the detection device is inside, away from the center of the detection device for the lateral side. As shown in figure 1, AR optical lens surface detection device, including bracket 1, stents, 1 2 1/2 and semi-permeable display screens are installed on the lens 3, stents, 1 including lenses can be placed under test is 4 lens holder, display 2 vertical set in the side of the lens holder, semi-permeable half the lens tilt 3 set above the lens holder, and respectively with display screen into acute Angle between 2 and lens holder. Lens bracket for two on stand 1 relative support table 11, the ends of the lens under test 4 placed on two supporting units respectively. As shown in figure 1, two support Taiwan 11 respectively has two 12, bend the arc of the arc of the radian of 12 with the standard of lens under test 4 at the ends of the curve is consistent, located on the same side of the two circular arc of 12 as a whole structure. Lens under test 4 lens under test in the left and right lens under test, the left lens under test and right lens under test were placed in the left side of the two circular arc 12 and two on the right side of the arc on the 12, among them, the left lens under test and the right edge of the lens under test fit together. As shown in figure 1 and figure 2, stents, 1 including floor 13 and 13 of the base and the two of the first support plate connected on both sides of the relative vertical 14, the first 14 for right-angled trapezoid structure support plate, under the right Angle trapezoid on the bottom edge and bottom edges are perpendicular to the floor 13; Two 14 set between the bottom edge of the first support plate has 15 second support plate; Support Taiwan 11 set between the first support plate on the bottom edge of 14 from one end of the floor 13. The first support plate 16, 14 of the upper connection plate with installation installed a semipermeable half the lens 3 in 16 and connection plate in the middle of the first support plate support platform between 11 14. The second support plate mounting plate 16 and 15 respectively connected with the third support plate outside of the 17, display 2 installed between two third support plate 17, display 2 third support plate connected with 17 in the outside of the baffle, baffle on two third support plate 17 set a respectively, also can be set up only two third 17 on any one of the support plate, can prevent the screen installation does not reach the designated position and display 2 from sliding out between the two third support plate 17. Among them, 13 floor, the first 14, 15 second support plate, support plate supporting table 11, mounting plate 16 and 17 third support plate as a whole structure. As shown in figure 2, this device detection, display 2 v test image, the image by a semipermeable half mirrors reflect 3 the lens under test 4, and then by the lens under test reflect four the semi-permeable half the lens 3, part of the image transmission over half and half the lens after 3, testers can stay in the lens under test 4 above observation lens imaging effect of 4. As shown in figure 1 and figure 2, in the upper part has a photo of the lens 4 under test equipment 5, 5 photo equipment connected with image analysis instrument. With photo equipment 5 the imaging effect pictures, and then import the picture image analyzer, by image analyzer on the analysis of the images to determine imaging effect. Semi-permeable half against the inside of the lens 3 coated or stick with a semipermeable membrane, can be adjusted according to the test needs a semipermeable half the lens 3 transmittance and reflectance, so that the final image to achieve the best effect. The utility model AR optical surface lens detection device, by observing the optical surface of lens imaging effect to detect the quality of optical lens surface to direct, short detection time, detection effect is good, the optical surface of the lens can be subjective objective full inspection, full inspection and can effectively avoid the bad product outflow and online, the device is simple, portable, and the products without damage, will not affect the subsequent use of the lens. Although the above describes the specific implementation of the utility model, but the field of technical personnel should understand, described the implementation of the case is only part of the utility model implementation example, rather than the implementation of all cases, these are just examples, the protection scope of the utility model is limited by the attached claims book. Technical personnel in the field does not deviate from the principle of the utility model and essence premise, under without any creative work, can make various implement ways for these changes or modifications, but these changes and modify all fall into the protection scope of the utility model.
