[0001] The utility model relates to the technical field of lens processing, and particularly relates to a polishing device for optical lenses. Background Technique

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical actions to reduce the surface roughness of a workpiece to obtain a bright and flat surface. Generally, it is a finishing process on the surface of the workpiece by a polishing tool and a polishing medium. When processing optical lenses, in order to reduce the surface roughness of the lens surface, polishing treatment is usually carried out.

[0003] For the Chinese patent "An Optical Lens Polishing Device", the authorized announcement number is "CN 220074216U". Through the setting of the processing chamber, it can block the fine particles generated during the polishing process to prevent them from scattering and affecting the health of the staff. Through the telescopic movement of the first electric push rod, the transmission plate drives the clamping block through the driving rod to clamp and fix the lens on the placement table, improving the processing quality.

[0004] Although the above application can polish optical lenses, a large amount of debris will be generated during the polishing process, and some debris will remain on the surface of the optical lens. Some debris during the grinding process of the grinding disc will cause scratches on the lens surface, thus affecting the grinding effect of the lens.

[0005] Therefore, a polishing device for optical lenses is proposed to solve the above problems. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] During specific implementation: As Figures 1-5 shown, a polishing device for optical lenses includes: an installation frame 1, a fixed plate 2 fixedly connected to the inner wall of the installation frame 1, two clamping plates 3 slidably connected to the top end of the fixed plate 2, a circular plate 4 fixedly connected to the middle of the top end of the fixed plate 2, a cylinder 5 fixedly connected to the top end of the installation frame 1, the bottom end of the cylinder 5 penetrating through the installation frame 1 and fixedly connected to a first motor 6, the output shaft of the first motor 6 fixedly connected to a grinding disc 7, and a cleaning mechanism 8 arranged at the top end of the fixed plate 2; wherein, the cleaning mechanism 8 includes a processing box 81 fixedly connected to the inner bottom wall of the installation frame 1, a fan 82 arranged on one side of the processing box 81, a gear ring 84 rotatably connected to the top end of the fixed plate 2, an annular pipe 85 fixedly connected to the top end of the gear ring 84, a plurality of circular pipes 86 fixedly connected to the surface of the annular pipe 85, a dust suction pipe 83 arranged inside the processing box 81, and the top end of the dust suction pipe 83 penetrating out of the processing box 81 and communicating with the annular pipe 85.

[0027] A driving motor is fixedly connected to one side of the fixed plate 2, a bidirectional lead screw is rotatably connected to the inner wall of the fixed plate 2, one end of the bidirectional lead screw is fixedly connected to the output shaft of the driving motor, and the inner walls of the two clamping plates 3 are threadedly connected to the surface of the bidirectional lead screw. When polishing an optical lens, place the optical lens on the circular plate 4, start the driving motor through the controller to drive the bidirectional lead screw to rotate, and the two clamping plates 3 can move and approach each other to clamp and fix the optical lens. After fixing, start the cylinder 5 to push the first motor 6 and the grinding disc 7 downward, make the bottom end of the grinding disc 7 contact the top end of the optical lens, and start the first motor 6 to drive the grinding disc 7 to rotate to polish the optical lens.

[0028] The circular plate 4 is arranged inside a plurality of circular tubes 86, and the horizontal height of the highest end of the circular tube 86 is lower than the horizontal height of the top end of the circular plate 4.

[0029] During grinding, the blower 82 in the cleaning mechanism 8 is started to discharge the air in the treatment box 81, so as to form a negative pressure in the treatment box 81. At this time, the dust suction pipe 83, the annular pipe 85 and the circular tube 86 will adsorb the debris and dust generated during grinding. The treatment box 81 is filled with an aqueous solution, and the debris and dust will be sucked into the treatment box 81 and mixed with the aqueous solution in the treatment box 81.

[0030] As Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in

[0031] When the first motor 6 drives the grinding disc 7 to rotate, it will drive the second gear 811 to rotate synchronously, thereby driving the first gear 810 to rotate synchronously. When the first gear 810 rotates, under the action of the limiting rod 816 and the limiting groove 817, it will drive the round rod 88 to rotate synchronously, thereby rotating the cam 812. When the cam 812 rotates from the lowest point to the highest point and contacts the contact plate 814, it will push the contact plate 814 to drive the rack 813 to move, and drive the gear ring 84 to rotate, so that the gear ring 84 drives the annular pipe 85 and the round pipe 86 to rotate. At the same time, the spring 815 is compressed. When the cam 812 rotates from the highest point to the lowest point and contacts the contact plate 814, the spring 815 loses extrusion and drives the rack 813 to reset, so that the gear ring 84 drives the annular pipe 85 and the round pipe 86 to rotate reversely and reset. Therefore, when the first motor 6 drives the grinding disc 7 to grind the optical lens, under the action of the first gear 810, the second gear 811, the cam 812, the spring 815 and the rack 813, the gear ring 84 will drive the annular pipe 85 and the round pipe 86 to rotate reciprocally to adsorb the dust and debris generated during grinding. One part of the dust suction pipe 83 is set as a flexible pipe.

[0032] When the air cylinder 5 pushes the first motor 6 to drive the second gear 811 to move downward, under the action of the connecting ring 87, it will drive the ring 89 to move downward synchronously, so that the first gear 810 and the second gear 811 move downward synchronously and always maintain meshing connection.

[0033] As Figure 4 shown, the other side of the contact plate 814 is fixedly connected with a slide bar 818, and the other end of the slide bar 818 sequentially penetrates the top of the spring 815 and the fixed plate 2. There is a convex block at the top of the fixed plate 2, and the other end of the spring 815 is fixedly connected to the surface of the convex block. The surface of the slide bar 818 is slidably connected to the inner wall of the convex block.

[0034] As Figure 2 、 Figure 3 and Figure 4 shown, multiple round pipes 86 are distributed annularly and equally, and the round pipes 86 are inclined. An angle is formed between the upper end of the surface of the round plate 4 and the vertical plane. The opening of the round pipe 86 is inclined upward, and the opening of the round pipe 86 corresponds to the position of the inclined surface of the surface of the round plate 4.

[0035] As Figure 2 shown, the diameter ratio of the second gear 811 to the first gear 810 is one to four. When the second gear 811 rotates one circle, the first gear 810 rotates one-fourth of a circle.

[0036] When the utility model is in use and grinding an optical lens, the optical lens is placed on the circular plate 4, and two clamping plates 3 are driven to move to clamp and fix the optical lens. After the fixing is completed, the air cylinder 5 is started to push the first motor 6 and the grinding disc 7 to move downward. During this process, under the action of the connecting ring 87, the circular ring 89 and the first gear 810 will move downward synchronously with the second gear 811. When the bottom end of the grinding disc 7 contacts the top end of the optical lens, the first motor 6 is started to drive the grinding disc 7 to rotate to grind the optical lens. At this time, the blower 82 is started to discharge the air in the treatment box 81, so that a negative pressure is formed in the treatment box 81. At this time, the dust suction pipe 83, the annular pipe 85 and the circular pipe 86 will adsorb the chips and dust generated during grinding. The chips and dust will be sucked into the treatment box 81 and mixed with the aqueous solution in the treatment box 81. At the same time, when the first motor 6 drives the grinding disc 7 to rotate, it will drive the second gear 811 and the first gear 810 to rotate synchronously, and under the action of the limiting rod 816 and the limiting groove 817, it will drive the round rod 88 and the cam 812 to rotate synchronously. When the cam 812 rotates, under the action of the spring 815, the contact plate 814 will drive the rack 813 to move reciprocally in the horizontal direction, and drive the toothed ring 84 to rotate reciprocally, so that the toothed ring 84 drives the annular pipe 85 and the circular pipe 86 to rotate reciprocally to adsorb the dust and chips generated during grinding. The end of the dust suction pipe 83 is provided with a flexible hose.

[0037] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
