Novel vertical driver for optical lenses

Abstract

The invention discloses a novel vertical driver for optical lenses, comprising a mounting seat, wherein an accommodating groove is formed in a side wall of a lower end of the mounting seat, mounting grooves are formed in side walls of both sides of the accommodating groove, upper grooves are formed in the side walls of upper ends of the mounting grooves, a rope body is connected to the side wall of one of the upper grooves through a power mechanism, lower grooves are formed in the side walls of the lower ends of the mounting grooves, gear racks are vertically arranged in the lower grooves, the gear racks pass through the mounting grooves and extend into the upper grooves, bottom walls of the lower grooves are connected with the gear racks through a reset mechanism, and the gear racks are slidably connected with the side walls of both sides of the lower grooves. By means of the mutual cooperation of the rope body, a telescopic spring and the gear racks and the like, the novel vertical driver disclosed by the invention can accurately drive an optical lens main body to ascend and descend, so that the adjustment precision is high, the service life is longer, in addition, the lens is brushed by a micro water pump, a nozzle and the like, so as to ensure the neatness of the lenses, and then the use effect of the optical lens main body is improved.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a novel vertical drive for optical lenses. Background technique [0002] Optical lenses are widely used and play an important role in photography, scientific research and daily life. Among them, optical glass lenses are more widely used. Optical glass is made of high-purity silicon, boron, sodium, potassium, and zinc. Oxides such as , lead, magnesium, calcium, barium, etc. are mixed according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasonic waves, and air bubbles are removed; then the temperature is slowly lowered for a long time to avoid internal stress in the glass block. The cooled glass blocks must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. [0003] By adjusting the vertical height of the optical lens to o...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem in the prior art that the adjustment of the height of the optical lens through the cooperation of the stepping motor and the precision screw is not accurate enough, and the surface of the optical lens will have dust attached to the surface during use, which will affect its normal use. A new type of vertical drive for optical lenses
