[0002] Optical lenses play an irreplaceable and crucial role in various fields due to their exquisite manipulation of light. From everyday mobile phone cameras to high-end astronomical telescopes, from projectors to optical imaging systems in medical equipment, optical lenses are ubiquitous, driving technological progress and improving the convenience of life. When processing optical lenses, it is necessary to polish their edges to make them the required size and ensure that their edges are smooth.

[0003] Currently, when grinding optical lenses, it is not convenient to center the optical lens. This leads to uneven grinding force on the edges, affecting the manufacturing quality of the optical lens. Therefore, we propose an optical lens grinding device to solve the above-mentioned problems. Utility Model Content

[0023] 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.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: an optical lens processing edge grinding device, including a base plate 1, a mounting frame 2 installed on the rear upper part of the base plate 1, a hydraulic rod 3 installed on the upper end of the mounting frame 2, a connecting frame 4 connected to the output end of the hydraulic rod 3, a mounting plate 5 connected to the lower end of the connecting frame 4, and a calibration component for center positioning of the optical lens provided on the mounting plate 5.

[0025] Furthermore, the calibration assembly includes a fixing plate 13 mounted on the outer edge of the mounting plate 5, a second spring 14 connected inside the fixing plate 13, a slide rod 15 connected to the end of the second spring 14, and a calibration plate 16 mounted on the lower end of the slide rod 15.

[0026] Furthermore, the upper and lower side walls of the calibration plate 16 are inclined, and the horizontal center line of the calibration plate 16 is flush with the lowest point of the pressing rod 12 in the initial state. First, the calibration plate 16 is used to center the optical lens, and then the pressing rod 12 gradually presses the optical lens.

[0027] A motor 6 is installed at the upper end of the connecting frame 4. A turntable 7 is connected to the output end of the motor 6. A limit ring 9 is installed on the outer side of the turntable 7. A connecting post 8 is installed on the lower side of the turntable 7. A spring 11 is connected inside the connecting post 8. A limit plate 10 is connected to the end of the spring 11. A pressing rod 12 is installed on the lower side of the limit plate 10.

[0028] Furthermore, the turntable 7 forms a rotating structure with the mounting plate 5 through the limiting ring 9. The vertical center line of the turntable 7 coincides with the vertical center line of the connecting column 8 and the pressing rod 12. The turntable 7 can drive the pressing rod 12 to rotate, and perform full edge grinding on the pressing rod 12 and the optical lens fixed to the turntable 18.

[0029] The pressing rod 12 forms an up-and-down sliding structure with the connecting column 8 through the limiting plate 10. Furthermore, the limiting plate 10 is a "+" shaped structure, which can be used to limit the movement of the pressing rod 12 in the connecting column 8, ensuring that the pressing rod 12 moves vertically in the connecting column 8, and that the connecting column 8 and the pressing rod 12 can rotate synchronously.

[0030] A support column 17 is installed above the base plate 1, and a turntable 18 is installed at the upper end of the support column 17; a hydraulic rod 19 is installed behind the mounting frame 2, the output end of the hydraulic rod 19 is connected to the mounting base 20, a motor 21 is installed on the upper side of the mounting base 20, and a grinding wheel 22 is connected to the output end of the motor 21.

[0031] Furthermore, the vertical center line of the pressure rod 12 coincides with the vertical center line of the turntable 18. The turntable 18 and the support column 17 form a rotating structure. The highest point of the turntable 18 is flush with the lowest point of the grinding wheel 22, so that the grinding wheel 22 can smoothly grind the optical lens, and the optical lens between the pressure rod 12 and the turntable 18 can rotate smoothly.

[0032] Specifically, the optical lens is placed on the turntable 18, and then the hydraulic rod 3 is opened, pushing the connecting frame 4 downward. At this time, the pressure rod 12 and the calibration plate 16 can be controlled to move downward. The calibration plate 16 first contacts the optical lens, pushing the optical lens to calibrate it at the center position of the turntable 18. According to the size of the optical lens, the calibration plate 16 can also be moved under force. The slide rod 15 installed on the side of the calibration plate 16 slides on the fixed plate 13, and the slide rod 15 compresses and stores the spring 14, so that the calibration plate 16 adapts to the size of the optical lens and calibrates it in the middle of the turntable 18. The pressure rod 12... When the bottom of the device is in contact with the optical lens on the turntable 18, the pressure rod 12 and the calibration plate 16 continue to move downward. At this time, the pressure rod 12 slides in the connecting column 8 under force, and the pressure rod 12 stretches and stores the force of the second spring 14. When the pressure rod 12 tightly presses the optical lens, the calibration plate 16 moves down to be offset from the optical lens, opening the second hydraulic rod 19 and pushing the mounting base 20 connected to the output end to move, thereby controlling the movement of the grinding wheel 22. The grinding wheel 22 is moved to be in contact with the edge of the optical lens, and the second motor 21 is powered on to control the grinding wheel 22 connected to the output end to rotate and grind the edge of the optical lens.

[0033] When motor 6 is powered on, the turntable 7 connected to the control output terminal rotates. At this time, the turntable 7 rotates on the mounting plate 5 through the limit ring 9, thereby causing the turntable 7 to drive the connecting column 8 to rotate. The connecting column 8 drives the pressure rod 12 to rotate, and the turntable 18 can also rotate on the support column 17 under force. Therefore, the optical lens locked between the turntable 18 and the pressure rod 12 can be smoothly driven to rotate, so that the grinding wheel 22 can perform full grinding on the optical lens. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
