Abstract

The invention discloses an automatic centering instrument. The automatic centering instrument is characterized in that the centering instrument comprises concentric upper and lower rings, wherein the diameter of the upper ring is smaller than that of the lower ring, and the edge of the upper ring is extended downwards and has chamfers; the centering instrument further comprises a frame with vertical rods and a transverse rod, wherein the lower parts of the vertical rods are connected with the edge of the lower ring; one end of a spring is connected with the center of the transverse rod, and the other end is connected with the center of the upper ring; and one end of a lifting rod penetrates through the transverse rod to be connected with the center of the upper ring, and the other end is connected with a handle. The automatic centering instrument is simple in structure, can position an optical lens automatically, and enables the cementing efficiency to be improved.

Description

[0001] technical field [0002] The invention relates to an auxiliary device for bonding optical lenses. Background technique [0003] Optical instruments Many lenses need to be glued optically. In gluing, the most important thing is that the two sheets to be glued should be aligned with the center, that is, the optical axes of the two lenses should not deviate too much. Now it is generally checked with a glued centering instrument. The gluing centering instrument is very complicated. The emitted light source with reticles is imaged on the eyepiece through two lenses. If the optical axes of the two lenses do not coincide, they form two images; if the optical axes coincide, the images overlap. This correction is not efficient. Contents of the invention [0004] The content of the present invention is to provide an automatic centering instrument. [0005] In order to achieve the above object, the following technical solutions are adopted: an automatic ce...
