Patent number: 8023208Abstract: A miniature stacked glass lens module is disclosed. The miniature stacked glass lens module includes at least one stacked optical glass lens element, a lens holder and other optical element. The stacked optical glass lens element is formed by cutting along alignment notches on a glued and stacked optical glass lens array. Then the stacked optical glass lens element and other optical element are mounted into the lens holder to form a miniature stacked glass lens module. Thereby the precise alignment of the optical axis of the lens in the lens module can be achieved. The manufacturing processes of the lens module can be simplified dramatically and the manufacturing cost is reduced significantly.Type: GrantFiled: September 9, 2009Date of Patent: September 20, 2011Assignee: E-Pin Optical Industry Co., Ltd.Inventors: San-Woei Shyu, Chih-Hsiung Huang, Chien-Lin Wu

Publication number: 20110102920Abstract: A lens displacement mechanism using shaped memory alloy (SMA) applied to an auto-focusing lens module is disclosed. The lens displacement mechanism comprising at least one SMA wire. Two opposite ends of the SMA wire are fixed and a longitudinal mid-point of an intermediate movable portion between the two opposite ends is tightened and is fixed on a corresponding hook disposed on an outer edge of the lens so that the intermediate movable portion is tightened between the two opposite ends. When the SMA wire is heated, the intermediate movable portion contracts to pull the hook of the lens for driving the lens to move and slide along with an optical axis so as to achieve auto-focus control. The present lens displacement mechanism is simple in structure and reflow process. Therefore, the present displacement mechanism is suitable to be used in portable camera or mobile phone or PDA, which needs to be small and have easily mass production by SMT.Type: ApplicationFiled: January 24, 2008Publication date: May 5, 2011Inventors: San-Woei Shyu, Shr-Bin Wu, Chih-Hsiung Huang

Patent number: 7268959Abstract: A lens module includes a lens set, a rotation base, an outer case, elastic members, a driving device having a stepping motor and a base frame. The lens set is fixed inside the rotation base that is elastically arranged between an upper case and a lower case by elastic members. By clockwise/counterclockwise rotation of the stepping motor outside the rotation base, the rotation base is driven to rotate. Furthermore, a plurality of sloped grooved surface that goes from shallow to deep and faces downwards is disposed on circular bottom surface of the rotation base and each sloped grooved surface presses homogeneously on a corresponding supporting point of the power case by elastic members. When the rotation base rotates, the sloped grooved surface moves relative to the supporting point so that the gap between the shallow and deep grooved surfaces becomes focusing travel. Furthermore, the base frame assembles or disassembles with the lens module by a fastening mechanism.Type: GrantFiled: August 3, 2005Date of Patent: September 11, 2007Assignee: E-Pin Optical Industry Co., Ltd.Inventors: San-Wuei Shyu, Chih-Hsiung Huang
