Lens and mold transfer system

Abstract

The invention discloses a lens and mold transfer system, which comprises a mold feeding part for feeding a mold discharged from a lens forming machine to a first position; a mold transfer unit that transfers the mold located at the first position to a second position in the first direction; a mold sending part which sends the mold at the second position into the lens forming machine; and an upper core pickup unit which is disposed at a third position between the first position and the second position, and is formed so as to pick up an upper core of the mold in order to take out the molded lens in the process of transferring the mold from the first position to the second position by the mold transfer unit, wherein the mold transfer unit includes a vibration module that is disposed between the first position and the third position and is formed so as to apply vibration to the mold before the upper core is picked up by the upper core pick-up unit.

Description

technical field [0001] The present invention relates to a system for transferring lenses and molds by connecting with a lens molding machine that molds incoming lens materials into a three-dimensional shape and then sends them out. Background technique [0002] In recent years, as digital cameras, camera phones, and network cameras have become smaller and thinner, the size of camera modules has gradually decreased. With the miniaturization of camera modules, the demand for aspheric lenses has increased significantly to replace existing spherical lenses. [0003] Although such aspherical lenses can be produced by grinding or press molding, grinding is not suitable for mass production. Therefore, in recent years, it is mostly used to put lens raw materials into the upper mold core and the lower mold core, and the upper mold core and the lower mold core are assembled together and then put into the lens molding machine. After high-temperature heating process, stamping process, ...
