DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application are clearly described below. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of this application.

[0018] This embodiment provides an automated optical lens calibration device for a sight, comprising: A base 1, wherein the base 1 is preferably a marble base 1, and rubber vibration isolation pads 10 are fixed around the bottom of the base 1. The entire device is supported by the base 1, effectively ensuring the flatness and rigidity of the base 1, isolating external vibrations, and thus improving the accuracy of calibration; the base 1 is set on a frame 11, and the frame 11 is provided with an outer cover 12, and the outer cover 12 is provided with a button 13 and an indicator light 14; Positioning mechanism 2, used for clamping the sight under test; The optical path simulation and visual detection mechanism 3 is provided on the base 1, and the positioning mechanism 2 is provided on the middle part of the optical path simulation and visual detection mechanism 3. The optical path simulation and visual detection mechanism 3 is used to generate a simulated optical path to generate a reference bull's eye and adjust the coincidence of the sight red dot; A multi-dimensional adjustment mechanism 4 is provided on the base 1 and is located next to the optical path simulation and visual detection mechanism 3, and is used to clamp the sight and achieve swing adjustment in six dimensions; A first adjustment mechanism 5 is provided on the base 1 and located outside the optical path simulation and visual detection mechanism 3, and is used to twist the adjustment screw on the outer side of the sight; A second adjustment mechanism 6 is provided on the base 1 and located outside the optical path simulation and visual detection mechanism 3, and is used to twist the adjustment screw on the other side of the sight, so as to adjust the red dot of the sight to coincide with the reference bull's eye through the cooperation of the first adjustment mechanism 5 and the second adjustment mechanism 6; The curing mechanism 7 is provided on the base 1 and is used for curing the glue on the lens of the calibrated sight.

[0019] In the present invention, a further implementation scheme is that the positioning mechanism 2 includes a fixture body seat 20, a reference seat 21 is fixed on the fixture body seat 20, two clamping cylinders 22 are provided on the fixture body seat 20, and an adsorption hole is provided on the reference seat 21. The adsorption hole is connected to a vacuum generator for generating negative pressure and adsorbing the aimer. The aimer is placed on the reference seat 21, and the aimer is fixed to the reference seat 21 by the two clamping cylinders 22. The product is loaded onto the reference seat 21, and the vacuum generator generates negative pressure to fix the product tightly on the reference seat 21 through the adsorption hole. At the same time, the clamping cylinder 22 fixes the product again to achieve double fixation.

[0020] In this embodiment, further, a first cylinder 23 is provided on the clamp body seat 20, and a probe 24 is connected to the output end of the first cylinder 23. A power supply 25 is also provided on the clamp body seat 20, and the probe 24 is connected to the power supply 25. The other end of the probe 24 is in conductive contact with the power supply part of the sight to power the sight, thereby providing 3V power supply for the sight, so that the sight can generate a red dot.

[0021] In this embodiment, further, the optical path simulation and visual detection mechanism 3 includes a first bracket 30, the first bracket 30 is fixed on the base 1, a collimator 31 is fixed on the top of the first bracket 30, a second bracket 32 ​​is also fixed on the first bracket 30, a beam splitter prism 33 is fixed on the front end of the second bracket 32, and a visual camera 34 is provided at the rear end and the lower end of the second bracket 32. The two visual cameras 34 are respectively photographed from the side and bottom of the beam splitter prism 33. The collimator 31 is used to generate a vertical simulated light path to the beam splitter prism. The collimator 31 generates a reference bull's eye and a bull's eye of the collimator 31 for correction. The collimator 31 generates a simulated light path that passes vertically through the sight and provides a simulated long-distance reference bull's eye. The simulated light path passes through the beam splitter prism 33, and the light path simulation and the two vertically arranged visual cameras 34 on the visual detection mechanism 3 converge the field of view to the reference bull's eye generated by the collimator 31 to perform overlap correction and parallax detection between the red dot and the reference bull's eye.

[0022] Furthermore, the optical path simulation and visual inspection mechanism 3 uses two vertically arranged visual cameras 34 (side and bottom) to refract the light path through the dichroic prism 33 to synchronously capture optical defects of the sight lens in the horizontal and vertical directions (such as lens scratches, bubbles, uneven coating, etc.). When the simulated light path of the parallel light tube 31 passes through the lens, if there are defects, it will cause abnormal light path scattering or refraction. The visual camera 34 captures the abnormal shadow or light spot deformation of the bull's eye image, and combines it with algorithm analysis to determine the defect type and location, thereby achieving high-precision coordinate positioning and deviation quantification in the two-dimensional plane of the sight.

[0023] Two vision cameras 34 capture the image shape of the red dot from different perspectives (side and bottom). For example, the horizontal camera checks the horizontal straightness of the red dot's edges, while the vertical camera checks its vertical symmetry (e.g., whether one side is flattened or the other rounded). Red dot shape distortion can cause deviations between the "aiming point" and "impact point" during actual aiming (e.g., the center of the distorted red dot is not the actual center of the optical path). This design simultaneously detects distortion during the calibration process. If the distortion exceeds a threshold, an alarm is triggered, preventing unqualified products from being passed to the next process and reducing accuracy risks during subsequent use. This allows for simultaneous detection of both shape distortion and symmetry of the sight's red dot.

[0024] Two vertically arranged visual cameras 34 (through a beam splitter prism 33) capture the position coordinates of the reference bull's eye and the sight's red dot in the X-axis (horizontal) and Y-axis (vertical) directions, respectively. Combined with image algorithms, they can accurately calculate the offset of the red dot relative to the reference bull's eye in a two-dimensional plane (e.g., an X-axis offset of 0.02mm and a Y-axis offset of 0.01mm), rather than simply determining "whether they overlap." Traditional calibration can only determine the approximate overlap status through the naked eye or a single camera, and cannot quantify the offset data. This design provides precise two-dimensional coordinate deviation values ​​to guide the first adjustment mechanism 5 and the second adjustment mechanism 6 to perform "targeted adjustment" (e.g., adjusting the twisting angle of the corresponding adjustment screw according to the X-axis offset), further improving calibration accuracy.

[0025] In this embodiment, further, the multi-dimensional adjustment mechanism 4 includes a first support seat 40, a second support seat 41, a third support seat 42, a fourth support seat 43, a fifth support seat 44, a first rotating assembly 45, a second rotating assembly 46, a third rotating assembly 47 and a clamping assembly 48, the first support seat 40 is fixed on the base 1, the second support seat 41 is connected to the first support seat 40 along the Y direction, the third support seat 42 is connected to the second support seat 41 along the X direction, and the fourth support seat 43 is vertically fixed on the third support seat 42. The fifth support seat 44 is connected to the fourth support seat 43 for movement along the Z direction. The clamping assembly 48 is installed on one side of the first rotating assembly 45. The clamping assembly 48 is used to clamp the sight. The first rotating assembly 45 can generate rotation along the Z direction. The second rotating assembly 46 is connected to the first rotating assembly 45. The second rotating assembly 46 drives the first rotating assembly 45 to rotate along the Y direction. The second rotating assembly 46 is connected to the third rotating assembly 47. The third rotating assembly 47 is connected to the fifth support seat 44. The third rotating assembly 47 drives the first rotating assembly 45 to rotate along the Y direction. A rotating assembly 45, a second rotating assembly 46 and a clamping assembly 48 rotate along the X direction. The first rotating assembly 45, the second rotating assembly 46 and the third rotating assembly 47 are consistent. The third rotating assembly 47 includes a second cylinder 470, a first positioning plate 471 and a second positioning plate 472. The first positioning plate 471 is slidably set on the fifth support seat 44, and the second positioning plate 472 is slidably set on the first positioning plate 471. The first positioning plate 471 is provided with a sixth support seat 49, and the second rotating assembly 46 is set on the sixth support seat 49. The second cylinder 470 is installed on the fifth support seat 44 and its output end is driven to connect to the side of the first positioning plate 471. The first positioning plate 471 and the second positioning plate 472 are matched through an arc surface, so that when the second cylinder 470 pushes the first positioning plate 471 to move, it pushes the second positioning plate 472 to rotate along the X direction. After the sight is clamped by the multi-dimensional adjustment mechanism 4, it performs linear movement of the three axes XYZ and rotation around the three axes XYZ, a total of six degrees of freedom. It is equipped with an execution software algorithm to calculate and then drive the freedom adjustment of the sight to achieve a correction effect.

[0026] When the multi-dimensional adjustment mechanism 4 drives the sight to swing and adjust in six dimensions (e.g., rotation around the X, Y, and Z axes), two vertically mounted vision cameras 34 consistently track the relative position of the red dot and the reference bull's eye from a vertical perspective. For example, when the sight is tilted about the X axis, the bottom camera focuses on vertical offsets, while the side camera focuses on horizontal offsets, ensuring complete capture of two-dimensional deviations in all positions. Using only a single camera, or one not positioned vertically, can result in image loss due to visual obstruction or optical path deviation during sight swing. The vertically mounted cameras cover all 2D detection requirements, ensuring seamless monitoring during multi-dimensional adjustment and providing data support for parallax correction in all positions.

[0027] Furthermore, two independent sets of image data are generated for the same reference target and red dot. An algorithm compares the consistency of these two sets of data (for example, whether the X-axis offset is within the tolerance range) to eliminate misjudgments caused by lens contamination or optical path interference with a single camera. Single-camera detection carries the risk of a "single point of failure" (e.g., dust on the lens causes image blur, which can be mistakenly interpreted as red dot offset). The vertical dual-camera design enhances the reliability of detection results through data cross-validation, reducing calibration errors caused by inherent device failures.

[0028] In this embodiment, the first adjustment mechanism 5 is consistent with the second adjustment mechanism 6. The first adjustment mechanism 5 includes a first slide 50, a second slide 51, a third slide 52, a torque motor 53, a dynamic torque sensor 54 and a screwdriver bit 55. The first slide 50 is fixed on the base 1, the second slide 51 is slidably set on the first slide 50, and the third slide 52 is movably set on the second slide 51. The torque motor 53 is fixed on the top of the third slide 52. The dynamic torque sensor 54 is connected to the output end of the torque motor 53, and the screwdriver bit 55 is fixed on the other end of the dynamic torque sensor 54. The screwdriver bit 55 is used to twist the adjustment screw on the sight. According to the relative position of the red dot and the reference bull's eye, the adjustment screw is adjusted by the screwdriver bit 55, so that the red dot and the reference bull's eye coincide with each other. At the same time, the dynamic torque sensor 54 generates a torque curve of the twisting process when twisting, so as to judge the red dot adjustment process performance of the product, including straightness, damping and whether there is any vibration.

[0029] In this embodiment, further, the curing mechanism 7 includes a slide cylinder 70 installed on the fixture body seat 20, the slide cylinder 70 is located above the positioning mechanism 2, and the UV lamp 71 is installed on the slide cylinder 70 through the fixing seat 72. After the calibration is completed, the glue on the sight is cured to maintain the optimal performance state of the product.

[0030] The reference seat 21 of the positioning mechanism 2 fixes the sight through the adsorption hole and the clamping cylinder 22. After the first cylinder 23 drives the probe 24 to power the sight and generate a red dot, the clamping assembly 48 of the multi-dimensional adjustment mechanism 4 clamps the sight and swings it with six degrees of freedom. At this time, the optical path simulation and the parallel light tube 31 of the visual detection mechanism 3 generate a reference bull's eye. After refraction by the dichroic prism 33, two vertically arranged visual cameras 34 capture the offset between the red dot and the bull's eye at different swing angles in real time; at the same time, the screwdriver 55 of the first adjustment mechanism 5 and the second adjustment mechanism 6 adjusts the adjustment screw under the monitoring of the dynamic torque sensor 54, records the corresponding relationship between the torque change and the offset at different angles, and combines the data to generate a dynamic response curve of the sight in all postures. This curve can reflect the accuracy stability of the sight when it is subjected to external force or angle change, solving the problem that traditional correction can only achieve static alignment and cannot evaluate the dynamic accuracy in actual use. When the UV lamp 71 of the curing mechanism 7 cures the lens, the visual camera 34 The minute drift of the red dot position during the curing process is monitored simultaneously to provide additional data for dynamic performance analysis.

[0031] The above embodiments are described. In the absence of conflict, the embodiments and features in the embodiments of this application are combined with each other. This application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are protected by this application.
