Description

Technical Field

[0001] This utility model relates to the technical field of contact lens processing, specifically to a demolding machine for silicone hydrogel contact lenses with a batch adsorption mechanism. Background Technology

[0002] A contact lens demolding machine is a device specifically designed to remove contact lenses from molds during the manufacturing process. Due to the special materials and shapes of contact lenses, traditional manual demolding methods are not only inefficient but also prone to damaging the lenses, affecting product quality and yield. Therefore, contact lens demolding machines have emerged to automate the demolding process and improve production efficiency and product quality.

[0003] Common silicone hydrogel contact lens release machines with batch adsorption mechanisms typically lack shock absorption devices. Vibration can cause lens displacement or deformation during the release process, affecting the lens's optical performance and wearing comfort. Furthermore, machine vibration during release can reduce overall equipment stability, impacting release accuracy and efficiency, thus negatively impacting user experience. Therefore, we propose a silicone hydrogel contact lens release machine with a batch adsorption mechanism. Utility Model Content

[0004] Technical Problem Solved: Addressing the shortcomings of existing technologies, this utility model provides a demolding machine for silicone hydrogel contact lenses with a batch adsorption mechanism. It offers advantages such as improved equipment stability and enhanced lens quality. A limiting ring is fitted onto the outer wall of the guide rod through a through hole. An anti-corrosion base plate at the bottom of the shock-absorbing base provides corrosion protection. Through the action of a shock-absorbing damper and a shock-absorbing elastic component, the limiting ring can move within the inner movable hole, simultaneously driving the connecting seat to move. This effectively reduces vibration during machine operation, improving the overall stability of the equipment. The limiting ring acts as a limiting and anti-detachment device within the inner movable hole. First and second rubber shock-absorbing rings enhance the shock absorption effect. Reducing vibration prevents lens displacement or deformation during demolding, ensuring the optical performance and wearing comfort of the lenses, and improving product qualification rate. Simultaneously, it reduces demolding failure rate, decreases the need for re-demolding, improves production efficiency, and shortens the production cycle, effectively solving the problems in the background technology.
