Description

TECHNICAL FIELD

[0001] The utility model relates to contact lens production technical field especially is related to a heat sealing system. BACKGROUND

[0002] Contact lenses belong to medical devices, and its main function is to correct the refractive errors of the human eye. Its production process is constantly iterating, from the traditional vial process to the adhesive bonding process and the heat sealing process.

[0003] The vial process is to put the contact lens into the vial and then inject an appropriate amount of preservative solution, and use a disposable lid for sealing. However, because the process is complex and the cost of vial manufacturing is high, it is not suitable for mass production of contact lenses.

[0004] The adhesive bonding process is to put the contact lens into the contact lens storage box, inject an appropriate amount of preservative solution, apply chemical adhesive between the contact lens storage box and the upper cover (or sheet / aluminum foil), and apply pressure. Through photo-curing / thermal curing / chemical reaction, the storage box and the upper cover are sealed and connected. However, the process is complex, the manufacturing cost is high, and the chemical adhesive pollutes the lens, so it is not suitable for mass production of contact lenses.

[0005] The most commonly used process at present is the heat sealing process. In the traditional heat sealing technology, hard contact is used between the welding head and the contact lens storage box. During heat sealing, there are problems of partial lack of welding or excessive welding force in some areas, which leads to unstable sealing effect. In the subsequent process, the contact lens storage box is not enough to withstand the pressure, which leads to product damage. When tearing the aluminum foil, it is easy to suddenly change the tearing force value, which makes it difficult to ensure the yield of the product. UTILITY MODEL CONTENTS
