AI Technical Summary

Technical Problem

In the current manufacturing of contact lens patterns, liquid materials are prone to sedimentation and stratification during storage and supply, resulting in uneven concentration, which affects the optical consistency and functional stability of the product. Furthermore, secondary sedimentation and disturbance can easily occur during material replenishment and mold transfer.

Method used

The device employs a disposable, replaceable container, combined with a fluid mixing and quantitative output component, a mold unit drive and positioning component, an in-cavity stirring component, and a liquid level metering and control component, to achieve homogenization, quantitative delivery, and automated control of liquid materials, avoiding contamination and errors caused by manual transfer and operation.

Benefits of technology

It achieves high efficiency, uniformity, and quantitative accuracy in liquid materials, significantly improves product consistency and production efficiency, reduces the risk of human intervention and contamination, and enhances the optical and functional stability of materials.

Abstract

This invention discloses a container device for manufacturing patterns on contact lenses, comprising: a shell; a chamber inside the shell, wherein a feeding unit for storing a curable liquid material is detachably and invertedly installed inside the chamber; and a fluid mixing and metering output component disposed at the outlet of the feeding unit, used to circulate and homogenize the liquid material within the feeding unit and to output a metered amount of material in response to a control signal. This invention utilizes a disposable, replaceable container for the feeding unit, installed inverted with the outlet facing downwards within the chamber. This allows the liquid material to naturally flow towards the outlet area under gravity during storage, while enabling rapid replacement without container cleaning. This effectively avoids cross-contamination caused by the curing of residual material and the decrease in purity after multiple uses, ensuring that each batch of material is independently and sealed for storage, thus improving material consistency and hygiene safety.
