An optical instrument for lens polishing

Abstract

The invention discloses an optical instrument for lens grinding, which comprises a body, a grinding cavity is arranged in the body, a placing plate is rotated in the grinding cavity, a picture frame is placed on the placing plate, and a picture frame is placed on the picture frame. A lens is placed, and the upper side of the lens is provided with a liftable stretching rod through a telescopic device. The outer periphery of the stretching rod is a spline structure, and a suction cup is installed at the lower end of the stretching rod. , use the laser to draw the grinding track on the lens to provide the shape accuracy during grinding, and grind the lens through the mutual cooperation of the automatic uniform rotation of the lens and the horizontal movement of the automatically rotating grinding wheel. During the grinding process, it can be observed through the optical device The grinding situation ensures the grinding accuracy. In addition, the glass or resin slag generated during grinding is collected downward through the recovery device to ensure the clarity of observation, and the slag will not fly and affect the grinding. It is formed once 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
