Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to an optical lens polishing device. 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. It is a finishing process that uses a polishing tool and abrasive particles or other polishing media to process the surface of the workpiece. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but aims to obtain a smooth surface or mirror gloss. Sometimes it is also used to eliminate gloss (matting). Optical lenses need to be polished by a polishing device during the production process.

[0003] After retrieval, the application number CN202320465929.6 discloses an optical lens polishing device, which includes a processing chamber, a base, a fixing mechanism, and a polishing machine. The processing chamber is arranged with an opening on one side. The base is arranged at the bottom of the processing chamber. The base is arranged as a hollow cavity. The fixing mechanism is arranged on the base. The polishing machine is arranged at the top of the processing chamber. A placing table is fixedly arranged at the middle position of the top of the base, and the placing table is arranged directly below the polishing machine. The utility model belongs to the technical field of optical lens processing, and specifically provides an optical lens polishing device with high practicability, simple use, effective fixation of the lens, ensuring its stability, improving the processing quality, eliminating the need for manual polishing, and improving the processing efficiency.

[0004] In this solution, a suction cup is used to adsorb and fix the other side of the optical lens, which is conducive to the stable polishing of the optical lens. However, this polishing method can only polish one side of the optical lens, and the optical lens needs to be flipped for polishing the other side, resulting in a significant reduction in polishing efficiency.

[0005] Therefore, an optical lens polishing device is proposed, which has the advantages of double-sided polishing and convenient collection of polishing debris, thereby solving the problems in the above background technique. Content of the Utility Model

[0007] To achieve the above object, the present utility model adopts the following technical solutions: An optical lens polishing device includes a polishing box. The front surface of the polishing box is hinged with a box door through a hinge, and a viewing window is embedded on the surface of the box door. A first motor is fixedly installed on the lower left side of the polishing box, and the output end of the first motor is fixedly connected with a bidirectional screw through a coupling. The end of the bidirectional screw far from the first motor is connected to the inner wall of the polishing box through a shaft seat. Two threaded sleeves are threadedly connected to the surface of the bidirectional screw, and the two threaded sleeves respectively penetrate through a partition plate and are fixedly connected with moving blocks.

[0013] The present utility model has the following beneficial effects:

[0014] In the present utility model, by starting the first motor to drive the bidirectional screw to rotate, it prompts the two threaded sleeves to move towards each other along the bidirectional screw respectively. During the stage of moving towards each other, it drives a set of corresponding moving blocks and mounting frames to move towards each other, so that the polishing discs connected by the second motor on the two mounting frames approach the two sides of the optical lens respectively.

[0025] In one embodiment, both the upper clamping frame 13 and the lower clamping frame 14 are semi-circular structures, and rubber strips 18 are embedded and installed on the inner sides of the upper clamping frame 13 and the lower clamping frame 14. Moreover, mounting seats 19 with a T-shaped structure are welded to the separated ends of the upper clamping frame 13 and the lower clamping frame 14. An arc surface is provided on the surface of the rubber strips 18 of the upper clamping frame 13 and the lower clamping frame 14. By placing the lens to be polished in the semi-circular lower clamping frame 14, and then starting the electric push rod 12 to push the semi-circular upper clamping frame 13 downward, so that after the upper clamping frame 13 and the lower clamping frame 14 are combined, the built-in rubber strips 18 are used to clamp the optical lens. On the one hand, the stability of the optical lens during the polishing stage is increased, and on the other hand, the setting of the rubber strips 18 can avoid clamping damage to the optical lens. Among them, the rubber strips 18 are arranged in a circular arc structure, and the arc surface is arranged on the concave surface of the rubber strips 18.

[0026] In one embodiment, a strip-shaped opening is provided on the top surface of the partition plate 5 corresponding to the threaded sleeve 7, and the partition plate 5 is in contact with the bottom surface of the moving block 8. Through the setting of the strip-shaped opening, it is easy for the threaded sleeve 7 to move.

With the above mounting method, the disassembly of the polishing disc 11 is facilitated for the replacement of the polishing disc 11.

[0028] In one embodiment, there are two sets of the threaded sleeve 7, the moving block 8, the mounting frame 9, the second motor 10 and the polishing disc 11, and the two sets of the threaded sleeve 7, the moving block 8, the mounting frame 9, the second motor 10 and the polishing disc 11 are symmetrically arranged about the vertical midline of the partition plate 5, and the two sets of the threaded sleeve 7, the moving block 8, the mounting frame 9, the second motor 10 and the polishing disc 11 are distributed on the left and right sides of the lower clamping frame 14.

Through the setting of the polishing disc 11, the polishing of the optical lens is facilitated. In order to cope with the polishing of the arc surface optical lens, a polishing concave surface is also provided on the polishing disc 11.

[0030] Working principle:

[0031] In use, first place the lens to be polished in the semi-circular lower clamping frame 14, and then start the electric push rod 12 to push the semi-circular upper clamping frame 13 downward. After the upper clamping frame 13 and the lower clamping frame 14 are combined, clamp the optical lens with the built-in rubber strip 18. When polishing, start the first motor 3 to drive the bidirectional screw 6 to rotate, prompting the two threaded sleeves 7 to move towards each other along the bidirectional screw 6 respectively, driving a set of corresponding moving blocks 8 and mounting frames 9 to move towards each other, so that the polishing discs 11 connected to the second motors 10 on the two mounting frames 9 approach both sides of the optical lens respectively. During this process, start the second motor 10 to drive the polishing discs 11 to rotate, so that the polishing discs 11 perform double-sided polishing on the optical lens. The debris generated during the polishing process falls into the collection boxes 16 respectively arranged on the left and right sides of the lower clamping frame 14. When there is more debris in the collection box 16, pull the collection box 16 to disengage the connecting sleeve 17 at the bottom from the socket of the support bar 15, facilitating the cleaning of the polishing debris. When the polishing of the optical lens is completed, start the electric push rod 12 to retract and reset, so that the upper clamping frame 13 disengages from the lower clamping frame 14, and then the optical lens can be taken out.
