Description

Technical Field

[0001] The utility model belongs to the technical field related to polishing devices, and specifically relates to a polishing device for producing optical lenses. Background Art

[0002] Optical lenses are essential components in machine vision systems, which directly affect the quality of imaging and the implementation and effectiveness of algorithms. Optical lenses are one of the important components in optical lenses. Optical lenses are devices that use optical principles to transform the image of an object. They transform light according to optical principles and transmit the image of the object to our eyes. Optical lenses have powerful optical functions and can change the shape and size of objects to make the image clearer. They can also realize the eraser function of the object image, making the image softer and having a certain protective effect. In addition, the characteristics of optical lenses can be used to realize the focusing function of the object, making the image clearer and the display more accurate. During the processing of optical lenses, polishing is required. The existing optical lens polishing device is mainly used for flat polishing of optical lenses. When arc polishing is required, it needs to be operated manually with the polishing equipment. The polishing efficiency is low and there are certain safety hazards.

[0003] In view of this, the present utility model is proposed. Utility Model Content

A fixed suction cup 5 is provided, and a polishing built-in trough structure 2 is provided on the table top of the main frame 1 below the fixed suction cup 5. A polishing power motor 3 is fixedly installed in the polishing built-in trough structure 2, and a polishing wheel 4 is installed on the main shaft of the polishing power motor 3. A lower stable bracket 25 is fixedly provided below the fixed support sleeve 14, and a matching mounting frame 24 is fixedly provided on the end of the lower stable bracket 25 away from the swing support seat 9. A matching wheel 23 is rotatably installed on the matching mounting frame 24, and an eccentric wheel 22 is provided on the side of the matching wheel 23. The eccentric wheel 22 is installed on the main shaft of the swing power motor 21, and the swing power motor 21 is fixedly installed on the main frame 1. The swing power motor 21 is used to provide power support for the rotation of the eccentric wheel 22.

[0025] Among them, the eccentric wheel 22 and the matching wheel 23 are located on the same horizontal plane, and a rear limit support frame 19 is fixedly provided on the side of the flip support seat 16 close to the swing power motor 21. The rear limit support frame 19 is an inclined structure arranged to limit the backward flipping of the flip frame 15.

[0026] An extension plate 26 is fixedly provided at the middle position of the hollow inner side of the flip frame 15, and a limit support nail 18 is installed on the extension plate 26 through a threaded connection. A front limit support plate 17 is fixedly provided on the side of the middle position of the fixed support sleeve 14 away from the rear limit support frame 19. The front limit support plate 17 cooperates with the limit support nail 18 to limit the forward flipping of the flip frame 15.

[0027] A mounting hole 27 is provided on the clamping fixing seat 7, and a through groove 28 is extended outward from the center of the mounting hole 27. A fixing screw 29 is installed between the corresponding surfaces of the through groove 28. A telescopic column is provided at the end of the clamping fixing seat 7 away from the through groove 28. The telescopic column is passed through the matching hole at the front end of the flip frame 15, and the extension position of the clamping fixing seat 7 is fixed by the telescopic adjustment locking screw 20 and can be adjusted as needed.

[0028] A press-fit counterweight 8 is installed on the outside of the fixed rod 6 above the clamping fixed seat 7. The press-fit counterweight 8 is provided with standard blocks of different weights. A through-hole structure that is compatible with the fixed rod 6 is provided at the center position of the press-fit counterweight to prevent the press-fit counterweight 8 from slipping off when the flip frame 15 swings with the swing rod 13.

[0029] A return spring 30 is provided on the side of the mounting frame 24, and the other end of the return spring 30 is fixedly connected to the outer side of the swing power motor 21. A bearing is provided at the connection position between the swing fixing seat 10 and the swing support seat 9. The upper end of the swing fixing seat 10 is installed with a swing arm locking screw 12 through a threaded connection. The swing arm locking screw 12 is used to lock the relative position of the swing arm 13 and the swing fixing seat 10.

[0030] The working principle of the utility model is as follows: when polishing the optical lens, the optical lens that has been roughly ground is wiped clean to keep it in a clean and dry state, the optical lens is installed under the fixed suction cup 5, and the relative position of the fixing rod 6 and the clamping fixing seat 7 is adjusted by the fixing screw 29 so that the optical lens and the polishing wheel piece 4 can effectively contact each other, and the telescopic position of the clamping fixing seat 7 is adjusted by the telescopic adjustment locking screw 20. The contact position of the optical lens and the polishing wheel piece 4 is adjusted according to the curvature of the lens polishing. The curvature of the center position of the polishing wheel piece 4 is smaller, and the curvature is smoother as it approaches the edge position. Through the adjustment of the position, the optical lens polishing has a good adaptability, and then a pressing counterweight block 8 of appropriate weight specification is selected and placed above the clamping fixing seat 7, and is sleeved on the outside of the fixing rod 6 to ensure that the optical lens and the polishing wheel piece 4 have appropriate pressure;

[0031] During polishing, the polishing power motor 3 works to drive the polishing wheel 4 to rotate. At the same time, the swing power motor 21 works to drive the eccentric wheel 22 to rotate. The eccentric wheel 22 contacts the matching wheel 23 during rotation. As the eccentric wheel 22 rotates, the swing rod 13 swings back and forth along the center of the swing fixing seat 10. The reset spring 30 is used to reset and limit the swing. During the swinging process, the optical lens and the polishing wheel 4 move relative to each other. At the same time, the polishing wheel 4 also rotates independently. The setting of the flip frame 15 and the pressing counterweight 8 can not only make the polished lens and the polishing wheel 4 effectively fit together, but also can perform adaptive adjustment of the flip angle in a small range according to the arc surface of the polishing wheel 4, to ensure that the optical lens is evenly stressed during the polishing process.

[0032] The utility model uses a structure consisting of an eccentric wheel 22, a swing rod 13, a flip frame 15, a fixed rod 6, and a fixed suction cup 5 to fix the optical lens. The swing rod 13 drives the optical lens to swing back and forth, and cooperates with the polishing wheel 4 to realize the polishing of the optical lens. The polishing surface of the polishing wheel 4 is provided with an arc surface structure and a plane structure, which can meet the polishing requirements of different types of optical lenses. The size of the pressure during the polishing process of the optical lens can be adjusted by replacing the press-fit counterweight block 8 without manual pressing, which has good safety, uniform force during the polishing process, and good polishing uniformity. Limited support devices are provided on both sides of the flip frame 15, which can provide limited support for the flipping of both sides of the flip frame 15.

[0033] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
