Description

Technical Field

[0001] This utility model relates to the field of automated production technology of contact lenses, specifically to an automated contact lens hydration device with automatic loading and unloading. Background Technology

[0002] Silicone hydrogel is an organic polymer material that is hydrophilic and has a dual-phase material framework, meaning it has both fluorosilicone and hydrogel channels. Silicone hydrogel lenses are a newly introduced contact lens manufacturing process in recent years. In the production of contact lenses, whether colorless or colored, the hydration process is crucial. It involves hydrating dry contact lenses to achieve the necessary water content and stabilize their shape. The hydration process also extracts low-molecular-weight substances or impurities from the lens. The hydration extraction process is critical to whether contact lenses will cause irritation or other reactions to the human eye. The extraction time, temperature, and amount of liquid used all affect the extraction results. In the current technology, there is no mature automated hydration extraction equipment in China for contact lenses made of silicone hydrogel materials with relatively complex hydration processes. Furthermore, due to the special nature of the hydration process, organic hydration solvents pose safety hazards to the work site and workers. Therefore, there is an urgent need for hydration equipment that can automate loading and unloading and enable unmanned hydration processes to meet the needs of silicone hydrogel contact lens manufacturing processes.
