Lens machining self separation and reunion technology and equipment

Abstract

The invention discloses a lens machining self separation and reunion technology. Lens plastic materials are injected into a die composed of a male die, a female die and a rubber ring, then the die obtained after injection molding is placed in a curing box to be cured, and after a lens is cured and formed, the rubber ring on the die is excavated away; and then the male die and the female die carrying the lens are placed in an ultrasonic cleaning machine to be cleaned, and after cleaning is thorough, the lens is released from the male die and the female die, and the cleaned lens and the cleaned die are obtained. The invention further discloses corresponding equipment. By means of the lens machining self separation and reunion technology and the equipment, lens machining is simpler and more environment-friendly, the production efficiency is high, cost is lower, and the die losses and the reject ratio of the lens are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of lenses, in particular to the lens processing self-clutching technology and the structure of equipment. Background technique [0002] In the prior art, when processing injection-molded lenses, the lens plastic material is first injected into a mold composed of a male mold, a female mold and an apron, and then the injected mold is put into a curing box for curing. After the lens is cured and formed, Dig out the rubber ring on the mold, then release the lens from the male mold and the female mold, and then use cleaning agent to clean the lens and the mold respectively to obtain the cleaned lens and mold, and reassemble the mold for the next It is used for one-time injection molding lens processing. [0003] Because the existing technology uses the lens and the mold to be released after curing, during the release process, the original greasy ingredients will cause environmental pollution and pollute the lens...

AI Technical Summary

Problems solved by technology

[0003] Because the existing technology uses the lens and the mold to be released after curing, during the release process, the original greasy ingredients will cause environmental pollution and pollute the lens and the mold at the same time. Therefore, the lens and the mold must be cleaned separately after release. In the future, not only will the process increase, but also the cleaning will be difficult, the amount of cleaning will be large, and the cleaning will be troublesome. There will also be cases of pollution and damage to the mold and lens. According to statistics, the loss of the mold is more than 3%, and the defective rate of the lens is more than 10%.
