Description

Technical Field

[0001] The utility model relates to an optical lens edge grinding mechanism, belonging to the technical field of optical lens grinding equipment. Background Art

[0002] Optical lenses are optical components used to refract or reflect light, usually made of glass or plastic. They can be designed into various shapes and curvatures to achieve different optical effects.

[0003] The prior art "Application No.: 2021225396997" discloses a synchronous transmission stop mechanism for an optical edge grinding machine. Through the synchronous transmission assembly, only one servo motor is needed to simultaneously drive the first and second spindles to rotate. The structure is ingenious and reduces manufacturing costs. In addition, the cam assembly can separate the grinding assembly from the optical lens, stop processing the optical lens, and facilitate the assembly and disassembly of the optical lens.

[0004] The defects of the above-mentioned prior art are: 1. The two ends of the synchronous shaft are connected to the first and second main shafts through gears, which has a transmission ratio between the gears, resulting in insufficient rotation speed of the first and second main shafts and low control accuracy; 2. The grinding assembly is controlled by the cam assembly to separate or contact it from the optical lens. Specifically, "the second servo motor starts to drive the camshaft to rotate, and the camshaft drives the cam to rotate, so that Figure 4 It can be seen that when the protruding part of the cam rotates to connect with the rotating wheel, the rotating wheel and the straight rod will be pushed up to the upper left, that is, the machine cover will rotate counterclockwise with the rotating shaft as the center. From the above structure, it can be seen that the grinding wheel is connected to the machine cover, so that the grinding wheel will move counterclockwise at a certain angle, thereby achieving the purpose of separating from the optical lens and stopping the processing of the optical lens; similarly, when the new optical lens is reinstalled on the core head between the first and second spindles, the cam is driven to rotate so that the non-protruding surface of the cam is connected to the rotating wheel, and the grinding wheel will reset and move clockwise at a certain angle, thereby achieving the purpose of contacting and grinding with the optical lens. The transmission structure is complex, resulting in low control accuracy of the grinding component position.

[0005] Therefore, how to provide an optical lens edging mechanism with high control precision is the research purpose of this utility model. Utility Model Content
