[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5As shown: An optical lens FOV testing machine includes a main structure, the main structure including a chassis 17. The chassis 17 is equipped with a loading / unloading robot 1, a multi-layer loading / unloading mechanism 3, a testing mechanism feeding robot 4, and an FOV detection mechanism 2. The loading / unloading robot 1 picks up the optical lens to be tested from the multi-layer loading / unloading mechanism 3 and places it on the testing mechanism feeding robot 4. The testing mechanism feeding robot 4 then transports the optical lens to be tested to the center of the FOV detection mechanism 2, where the FOV detection mechanism 2 performs testing on the optical lens. The loading / unloading robot... Hand 1 includes two sets of opposing mounting side frames 16. Each mounting side frame 16 is equipped with a Z-axis drive mechanism 13, an X-axis drive mechanism 12, and a Y-axis drive mechanism 11. The Y-axis drive mechanism 11 is equipped with a material suction pen assembly. The material suction pen assembly includes a first material suction pen 7, a second material suction pen 10, and two material suction pen suction / release control cylinders 18. Each of the two suction pen suction / release control cylinders 18 independently controls the first material suction pen 7 and the second material suction pen 10, respectively, via the Z-axis drive mechanism 13 and the X-axis drive mechanism 11. The drive mechanism 12 and the Y-axis drive mechanism 11 drive the position movement of the suction pen 7 and the suction pen 10, realizing the transfer of the lens to be tested and the lens that has been tested. The suction and release control cylinder 18 controls the suction and release of the suction pen 7 and the suction pen 10 respectively. The multi-layer loading and unloading mechanism 3 includes a tray drive slide rail 19 and a tray drive slide rail 20. The tray drive slide rail 19 is provided with a lens tray 8 slidably connected to it, and the tray drive slide rail 20 is provided with a lens tray 21 slidably connected to it. The tray drive slide rail 19 and the lens tray 21 are connected to each other. The second drive slide rail 20 drives the first lens tray 8 and the second lens tray 21 to move back and forth, realizing the back-and-forth transport of the lens to be tested and the lens that has been tested; the feeding robot arm 4 of the testing mechanism includes a material platform drive mechanism 15, a material platform frame 14 is provided on the material platform drive mechanism 15, and a testing mechanism unloading platform 9 is installed on the material platform frame 14. The material platform drive mechanism 15 drives the testing mechanism unloading platform 9 to move back and forth, realizing the incoming material testing and transport; the FOV testing mechanism 2 includes multiple sets of testing instrument mounting arms 6 arranged in a circle, and a testing instrument 5 is installed and connected to the testing instrument mounting arm 6.

[0027] It should be noted that the mounting side frame 16 is provided with a Z-axis drive mechanism 13, and the X-axis drive mechanism 12 is mounted and connected to the Z-axis drive mechanism 13. The X-axis drive mechanism 12 includes a lateral adjustment slide rail and a lateral adjustment slider slidably connected thereto. The Y-axis drive mechanism 11 is mounted on the lateral adjustment slider. Through the combined arrangement of the Z-axis drive mechanism 13, the X-axis drive mechanism 12 and the Y-axis drive mechanism 11, the multi-axial movement control of the suction pen assembly is realized, thereby meeting the transfer requirements of the optical lens.

[0028] It should be noted that the tray drive slide rail 19 and the tray drive slide rail 20 are located between the two sets of mounting side frames 16, and the tray drive slide rail 19 and the tray drive slide rail 20 are arranged parallel to each other. The platform drive mechanism 15 is located between the tray drive slide rail 19 and the tray drive slide rail 20, and the platform drive mechanism 15 is parallel to the tray drive slide rail 19 and the tray drive slide rail 20. The height of the tray drive slide rail 19 is higher than the height of the tray drive slide rail 20, so that the lens tray 8 is located above the lens tray 21, realizing alternating feeding of the upper and lower layers, reducing downtime, and thus improving detection efficiency.

[0029] It should be noted that the mounting arm 6 of the detector has an arc-shaped structure, and the detector 5 is adjustablely mounted on the mounting arm 6. The detector 5 is provided with an adjustment component, and the mounting arm 6 is provided with an adjustment groove. The edge of the adjustment groove is provided with scale lines. The position of the detector 5 on the mounting arm 6 can be adjusted according to the model of the optical lens. By setting up multiple sets of detectors 5, multi-angle detection of the optical lens can be achieved, effectively improving the detection quality.

[0030] Working principle: The operator places lens tray 1 (8) and lens tray 2 (21) containing the optical lenses to be tested onto tray drive rails 19 and 20. The trays 19 and 20 then move them to the front of the loading / unloading robot 1. The suction pen control cylinder 18 controls the suction pen 7 to pick up the optical lenses to be tested from lens tray 18. The suction pen 7 is then moved to the testing mechanism feeder via the Z-axis drive mechanism 13, X-axis drive mechanism 12, and Y-axis drive mechanism 11. At point 4, the robotic arm places the optical lens to be tested onto the loading platform 9 of the testing mechanism. The loading platform 9 is moved to the center of the FOV testing mechanism 2 by the loading platform drive mechanism 15. Multiple sets of testing instruments 5 then test the optical lens. After testing, the loading platform 9 is driven back by the loading platform drive mechanism 15. Simultaneously, the suction pen 2 10 picks up the lens to be tested from the lens tray 21. After the tested optical lens returns, the suction pen suction and release control cylinder 18 controls the suction pen 1 7 to pick up the tested optical lens from the loading platform 9 of the testing mechanism. Cylinder 18 controls suction pen 7 to pick up lens material tray 8. Suction pen suction and release control cylinder 18 controls suction pen 2 10 to place the lens to be tested onto the inspection mechanism's loading platform 9. The loading platform 9 is moved to the center of the FOV inspection mechanism 2 by the loading platform drive mechanism 15. Multiple inspection instruments 5 inspect the optical lenses. Simultaneously, the X-axis drive mechanism 12 and Y-axis drive mechanism 11 drive suction pen 7 and suction pen 2 10 back. Suction pen 7 places the inspected optical lens back to its original position on lens material tray 8, and then picks up other lenses to be tested from lens material tray 8. After the optical lens is inspected, the material platform drive mechanism 15 drives the inspection mechanism's unloading platform 9 to return. The X-axis drive mechanism 12 and the Y-axis drive mechanism 11 drive the suction pen 1 7 and suction pen 2 10 to move. Suction pen 2 10 retrieves the inspected optical lens from the inspection mechanism's unloading platform 9. Suction pen 1 7 places the optical lens to be inspected on the inspection mechanism's unloading platform 9. The material platform drive mechanism 15 drives the inspection mechanism's unloading platform 9 to move to the center of the FOV inspection mechanism 2. Multiple sets of inspection instruments 5 inspect the optical lens. This process is repeated to test the lens to be inspected.
