Detailed implementation manners

[0040] The following will specifically describe the preferred embodiments of the present invention with reference to the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principle of the present invention, rather than to limit the scope of the present invention.

[0041] Please refer to Figures 1 to 5, the diopter magnification detector 100 includes a workbench 1 and a detection mechanism 3; the workbench 1 is provided with an object position 11 and a detection position 12 along its longitudinal direction. The object position 11 is provided with a mounting bracket 13 for mounting the lens 200 to be detected. On the side of the mounting bracket 13 away from the detection position 12, a light source assembly 2 for arranging the observation pattern 300 is provided. The detection position 12 is provided with an imaging platform 14 and an image transmission platform 15. The imaging platform 14 is movably arranged along the longitudinal direction of the workbench 1. The image transmission platform 15 is arranged at one end of the imaging platform 14 away from the object position 11 and can move along the longitudinal direction of the workbench 1 relative to the imaging platform 14; the detection mechanism 3 includes an imaging component 31 arranged at one end of the imaging platform 14 close to the object position 11 and an image transmission component 32 arranged on the image transmission platform 15 and corresponding to the imaging component 31. The imaging component 31 is used to convert the imaging of the lens 200 to be detected into a real image. The image transmission component 32 is electrically connected to a computer and is used to obtain the real image formed by the imaging component 31 and transmit it to the computer for detection.

[0042] In the diopter magnification detector 100 provided by the present invention, since the image transmission platform 15 can move along the longitudinal direction of the workbench 1 relative to the imaging platform 14, the optical distance between the image transmission component 32 and the imaging component 31 can be adjusted relatively, so that the detector has a telescopic mode capable of measuring diopter and a microscopic mode capable of measuring magnification. When the detector is in the telescopic mode, by driving the image transmission platform 15 to move relative to the imaging platform 14, the image transmission component 32 moves back and forth at the focal plane of the imaging component 31, and the actual position of the image transmission component 32 is fed back to the computer. Combining with the real image transmitted by the image transmission component 32 to the computer, the diopter of the lens to be detected can be obtained. When the detector is in the microscopic mode, the imaging platform 14 is driven to move along the longitudinal direction of the workbench 1 to change the optical distance between the imaging component 31 and the lens 200 to be detected. When the image transmission component 32 obtains the clearest imaging, the driving of the imaging platform 14 is stopped, the diameter of the clearest imaging is measured, and then according to the entrance pupil size of the observation pattern 300, the magnification of the lens 200 to be detected is calculated. This solution has high measurement accuracy, simple and convenient operation, and can perform diopter and magnification detection, with good practicability.

[0043] It should be noted that in this embodiment, the lens 200 to be inspected is the sight to be inspected. In addition, the imaging assembly 31 is composed of an objective lens 311, a lens frame, a fixing seat, etc. The objective lens 311 is of the form of a doublet lens. Specifically, in this embodiment, the doublet lens includes a first objective lens and a second objective lens arranged in sequence along the direction close to the image transmission assembly 32. The two sides of the first objective lens in the optical axis direction are convex surfaces, and one side of the second objective lens close to the first objective lens is a concave surface and the other side is a convex surface. In one embodiment, the focal length of the objective lens 311 is set to 80 mm, and the effective aperture is set to 20 mm, with small light energy loss and convenient installation. In addition, a light shield is provided corresponding to the objective lens 311 to eliminate the influence of stray light, improve the imaging quality, and further improve the detection accuracy. In the example of the attached drawings, the longitudinal direction of the workbench 1 is shown as F1.

[0044] And in this embodiment, the image transmission assembly 32 adopts a CCD (Charge Coupled Device) module, and the CCD module transmits the image formed by the objective lens 311 to the computer. In one embodiment, the CCD target surface is set to 1.1 inches, the resolution is 5120×5120, and the pixel is 2.5×2.5 μm. In this embodiment, when the CCD is located at the focal plane of the objective lens 311, the detector works in the telescopic mode and has the function of diopter measurement; when the CCD is located at the 1.5-fold focal length position of the objective lens 311, the detector works in the microscopic mode and has the function of magnification measurement. It should be understood that in the telescopic mode, the actual position feedback of the image transmission assembly 32 can be measured by the operator and input into the computer, or in other forms. In this embodiment, a sensor is correspondingly provided to monitor the actual position of the image transmission assembly 32 and feedback it to the computer.

[0045] Furthermore, to improve the imaging quality, in this embodiment, please refer to Figure 6 , an adjustment table 4 is provided between the imaging platform 14 and the workbench 1. The adjustment table 4 is movably connected to the imaging platform 14 for adjusting the optical axis direction of the imaging assembly 31. In this way, the optical axis deviation between the imaging assembly 31 and the sight to be inspected can be eliminated, and it can be adjusted adaptively according to the actual situation to improve the imaging quality and further improve the detection accuracy. At the same time, it is also convenient to be applicable to sights to be inspected of different sizes and improve the versatility.

[0046] Even further, please refer to Figure 6 and Figure 7, the adjustment stage 4 includes a pitching adjustment stage 41 located at the detection position 12. The upper side surface of the pitching adjustment stage 41 is the adjustment surface; the imaging platform 14 is arranged on the adjustment surface, and the lower side surface of the imaging platform 14 is the mating surface. One of the adjustment surface and the mating surface is set as an arc convex surface, and the other is correspondingly set as an arc concave surface. A first driving part 411 is arranged between the adjustment surface and the mating surface. The first driving part 411 is used to drive the mating surface to slide along the circumferential direction of the adjustment surface to adjust the pitching angle of the imaging platform 14, so that the optical axis direction of the imaging assembly 31 can be adjusted. In this solution, the adjustment surface is set as an arc concave surface, the mating surface is set as an arc convex surface, and the mating surface is provided with threads. Correspondingly, the first driving part 411 is a pitching adjustment screw arranged on the pitching adjustment stage 41, and the pitching adjustment screw cooperates with the mating surface of the imaging platform 14. Thus, the pitching angle of the imaging assembly 31 can be adjusted by rotating the pitching adjustment screw to drive the mating surface to slide along the circumferential direction of the adjustment surface, so as to quickly adjust the optical path.

[0047] Specifically, the adjustment stage 4 further includes a yaw adjustment stage 42 located at the detection position 12. The pitching adjustment stage 41 is rotatably arranged on the yaw adjustment stage 42 around an axis in the vertical direction, and a dial rod 421 protrudes from the side wall of the pitching adjustment stage 41, which is used to drive the pitching adjustment stage 41 to rotate around the axis in the vertical direction when an external force is applied, so as to adjust the yaw angle of the imaging platform 14. In this solution, the dial rod 421 is toggled to drive the yaw adjustment stage 42 to rotate, and then the yaw angle of the imaging assembly 31 is adjusted. The structure is simple and the operation is convenient.

[0048] Specifically, to improve the adjustment accuracy, in this embodiment, please refer to Figure 8 and Figure 9 , the adjustment stage 4 further includes a yaw fine adjustment screw 422 and a yaw fine adjustment seat 423 fixed to the side wall of the yaw adjustment stage 42. The upper end of the yaw fine adjustment seat 423 is correspondingly arranged for the pitching adjustment stage 41 and penetrates through an avoidance channel 423a along the direction close to the pitching adjustment stage 41. Threaded holes are tapped on the side wall of the avoidance channel 423a, and the yaw fine adjustment screw 422 is passed through the threaded holes and extends into the avoidance channel 423a; the pitching adjustment stage 41 is provided with a driving block 412 corresponding to the yaw adjustment seat. The driving block 412 partially extends into the avoidance channel 423a and corresponds to the threaded holes. One end of the yaw fine adjustment screw 422 extending into the avoidance channel 423a can abut against the side wall of the driving block 412. In this way, the driving block 412 arranged on the pitching adjustment stage 41 can be driven by rotating the yaw fine adjustment screw 422, so as to drive the pitching adjustment stage 41 to make a fine adjustment, and then improve the adjustment accuracy of the yaw angle.

[0049] It can be understood that the width of the avoidance channel 423a can be enlarged to increase the rotation stroke when the dial rod drives the pitching adjustment stage 41 to rotate, and then reduce the interference effect between the driving block 412 and the yaw fine adjustment seat 423.

[0050] Furthermore, the adjustment table 4 further includes a height adjustment table 43 located at the detection position 12 and provided at the lower end of the yaw adjustment table 42. One of the height adjustment table 43 and the yaw adjustment table 42 is provided with a vertical slide rail, and the other is provided with a vertical chute corresponding to the vertical slide rail, so that the height of the imaging platform 14 can be adjusted. Among them, a second driving part 431 is provided on the height adjustment table 43, and the second driving part 431 is drivingly connected to the yaw adjustment table 42 for driving the yaw adjustment table 42 to move in the vertical direction. In this embodiment, through the cooperation of the height adjustment table 43 and the yaw adjustment table 42, the height adjustment of the imaging platform 14 can be realized, making the optical axis adjustment of the imaging assembly 31 more flexible. Specifically, in this embodiment, the second driving part 431 is a height adjustment screw. The yaw adjustment table 42 is provided with a driven rack corresponding to the height adjustment screw, and the height adjustment table 43 is provided with an avoidance groove corresponding to the driven gear. The height adjustment screw is engaged with the driven rack, so as to drive the yaw adjustment table 42 to move in the vertical direction by rotating the height adjustment screw. It should be noted that in the attached drawing example, the vertical direction is shown as F2.

[0051] Even further, the adjustment table 4 further includes a lateral adjustment table 44 located at the detection position 12 and provided at the lower end of the height adjustment table 43. One of the lateral adjustment table 44 and the height adjustment table 43 is provided with a lateral slide rail, and the other is provided with a lateral chute corresponding to the lateral slide rail, so that the imaging platform 14 can move laterally along the workbench 1. Among them, a third driving part 441 is provided on the lateral adjustment table 44, and the third driving part 441 is drivingly connected to the height adjustment table 43 for driving the height adjustment table 43 to move laterally along the workbench 1. Specifically, the third driving part 441 is set as a lateral adjustment screw. A matching block protrudes from the side wall of the height adjustment table 43 corresponding to the lateral adjustment screw. One end of the lateral adjustment screw abuts against the matching block, so as to be able to drive the matching block to move laterally, and further drive the height adjustment table 43 to move laterally. It should be noted that in the attached drawing example, the lateral direction of the workbench 1 is shown as F3.

[0052] Furthermore, the adjustment table 4 further includes a longitudinal adjustment table 45 provided on the workbench 1 and located at the detection position 12. The longitudinal adjustment table 45 is provided at the lower end of the lateral adjustment table 44, and one of the longitudinal adjustment table 45 and the workbench 1 is provided with a longitudinal slide rail, and the other is provided with a longitudinal chute corresponding to the longitudinal slide rail. Specifically, in this embodiment, the longitudinal slide rail is provided on the workbench 1, and the longitudinal chute is provided on the lateral adjustment table 44. And the adjustment table 4 further includes a longitudinal locking structure. The longitudinal locking structure includes a longitudinal locking screw provided on the longitudinal adjustment table 45 and a locking plate located at one end of the longitudinal locking screw. By rotating the longitudinal locking screw, the locking plate is tightened against the longitudinal slide rail, so as to be able to limit the movement of the longitudinal adjustment table 45.

[0053] In addition, in this embodiment, the imaging platform 14 further includes an installation platform 141 and a connection platform 142 which are arranged vertically. The connection platform 142 is movably connected to the pitching adjustment platform 41. Among them, the mating surface is formed on the lower side surface of the connection platform 142. The installation platform 141 is slidably arranged on the upper side of the connection platform 142 along the longitudinal direction of the workbench 1. The imaging assembly 31 is arranged at one end of the installation platform 141 close to the object position 11, and the image transmission platform 15 is arranged at one end of the installation platform 141 away from the imaging assembly 31. It should be noted that the connection platform 142 and the installation platform 141, and the image transmission platform 15 and the installation platform 141 are respectively slidably arranged through a slide rail and a slide groove.

[0054] Further, in order to prevent the pitching adjustment platform 41 from accidentally moving after the height adjustment is in place, in this embodiment, a first locking plate 432 is provided on the side wall of the height adjustment platform 43.
