Optical instrument for lens grinding

Abstract

The invention discloses an optical instrument for lens grinding. The optical instrument comprises a machine body, a grinding cavity is formed in the machine body, a placing disc is rotationally arranged in the grinding cavity, a frame is placed on the placing disc, a lens is placed on the frame, a liftable stretching rod is arranged on the upper side of the lens through a telescopic device, the periphery of the stretching rod is of a spline-shaped structure, and a suction cup is mounted at the lower end of the stretching rod. According to the shape and sizes of the frame, a grinding trace lineis scribed on the lens through lasers, and the appearance precision during grinding is improved. The lens is ground through mutual cooperation of automatic constant-speed rotation of the lens and horizontal movement of an automatic rotating grinding wheel, and the grinding precision can be ensured by observing the grinding condition through an optical device in the grinding process. In addition,glass or resin slag generated during grinding is collected downwards through a recycling device, the observation clarity is guaranteed, grinding cannot be influenced because the slag cannot fly, one-time forming is achieved, and the grinding efficiency is high.

Description

technical field [0001] The invention relates to the technical field of glasses, in particular to an optical instrument for polishing lenses. Background technique [0002] The lens is a transparent material with one or more curved surfaces made of optical materials such as glass or resin. After being polished, it is often assembled with the spectacle frame to form glasses, which is used to correct the user's vision and obtain a clear vision. Among them, the lens is polished and shaped The process is particularly important. In the existing lens grinding, the lens is usually manually held, and the edge of the lens is in contact with the rotating grinding wheel to polish the lens. During the grinding process, the polisher needs to customize the shape of the lens according to the size of the frame or rely on experience. And the size, need to stop after polishing once, assemble and compare the lens with the frame, and then continue to polish and debug until the two are perfectly a...

[0002] The lens is a transparent material with one or more curved surfaces made of optical materials such as glass or resin. After being polished, it is often assembled with the spectacle frame to form glasses, which is used to correct the user's vision and obtain a clear vision. Among them, the lens is polished and shaped The process is particularly important. In the existing lens grinding, the lens is usually manually held, and the edge of the lens is in contact with the rotating grinding wheel to polish the lens. During the grinding process, the polisher needs to customize the shape of the lens according to the size of the frame or rely on experience. And the size, need to stop after polishing once, assemble and compare the lens with the frame, and then continue to polish and debug until the two are perfectly assembled. During this process, when the lens is held by hand, the surface of the lens will be damaged, and the adjustment and shutdown will be repeated. Resulting in low grinding efficiency and poor grinding accuracy
