Automatic suction and release mechanism for contact lenses

The utility model provides an automatic contact lens sucking and releasing mechanism which is used for sucking a contact lens in a contact lens tray, the contact lens is arranged in a groove in the contact lens tray, and liquid such as water can be injected into the groove. The automatic suction and release mechanism for the contact lenses comprises a lens adsorber for adsorbing the contact lenses by applying vacuum suction force; the lens adsorber internally comprises a cavity, one end of the cavity is connected with an airflow pipeline, and at least one air exhaust hole is formed in the other end of the cavity and communicated with the outside. During use, the lens adsorber is moved to be close to the contact lens, the cavity is subjected to air exhaust through the air flow pipeline, and the contact lens is sucked by applying vacuum adsorption force, so that the contact lens is separated from the groove bottom of the groove, and the contact lens is sucked from the contact lens tray; the lens adsorber can al
