Description

Technical Field

[0001] The utility model relates to the technical field of lens front and back identification, in particular to a lens front and back identification device for a full-automatic precision grinding machine. Background Technique

[0002] Optical glass is made by mixing oxides of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melting at high temperature in a platinum crucible, stirring evenly with ultrasonic waves to remove air bubbles; then cooling slowly for a long time to avoid internal stress in the glass block. The cooled glass block must be measured by optical instruments to check whether its purity, transparency, uniformity, refractive index and dispersion rate meet the specifications.

[0003] Traditional lenses generally have a convex surface on one side and a flat surface on the other side, and the precision grinding tooling used for processing them also has slight differences. Therefore, before being put into a full-automatic precision grinding machine, it is necessary to adjust the front and back sides of the lenses. When adjusting, a front and back identification head and a rotatable fixture are used for operation. After the identification is completed, a mechanical suction cup sucks it into the material. However, if the lens does not need to be adjusted, the waiting time of the mechanical suction cup is short, and if it needs to be adjusted, the waiting time of the mechanical suction cup is long. Among them, not only complex program design is required, but also there is ineffective waiting time, and there is still a certain degree of inconvenience in actual use. Therefore, there is an urgent need for a lens front and back identification device for a full-automatic precision grinding machine to solve the above problems. Content of the Utility Model
