Patent number: 10965870Abstract: An image capturing module having multiple lenses, in which primary driving magnets of auto-focus module equipped in a first lens module and a second lens module will not cover an adjacent surface located between these two lens modules in the same time. A relatively smaller magnet is used to be the auxiliary driving magnet of optical image stabilization (OIS) module equipped in the first lens module and the second lens module. By using the aforementioned configuration of the primary and auxiliary driving magnets, interference of magnetic fields is minimized, and thus the distance between the first and second lens modules can be decreased, and the space of mobile phone having the image capturing module is saved. Moreover, such configuration can be used on the image capturing module having many lens modules.Type: GrantFiled: March 20, 2020Date of Patent: March 30, 2021Assignee: PowerGate Optical Inc.Inventors: Ying Chun Huang, Yu Chia Chen, Hsieh Jen Chuang, Te Pao Ho, Shih Chan Wen

Publication number: 20210014395Abstract: A multi-lens camera module comprises at least two lens modules located side-by-side. Each lens module can be a voice coil motor (VCM) lens module having an auto-focusing (AF) or/and an optical image stabilizer (OIS) functions. The surface where two lens modules are adjacent with is called the neighbouring surface. A projection view on the neighbouring surface of a plurality of secondary driving magnets of these lens modules located at two sides of the neighbouring surface includes at least one secondary driving magnet which has two opposite edges with unequal length; in addition, shapes of these two opposite edges include at least one of the following: slope, arc and straight line. These secondary driving magnets are arranged across the neighbouring surface in a staggered manner.Type: ApplicationFiled: September 27, 2020Publication date: January 14, 2021Applicant: PowerGate Optical Inc.Inventors: Ying Chun Huang, Yu Chia Chen, Hsieh Jen Chuang, Te Pao Ho

Publication number: 20200333556Abstract: A moving-coil closed-loop auto-focusing module with low magnetic interference includes an upper cover, a base frame, a lens module, an elastic module, at least one coil, at least one pair of two opposing driving magnets, an external circuit and at least one sensor magnet. The coil surrounds the lens module. The two driving magnets are located individually at respective lateral sides of the base frame in correspondence with the coil. The external circuit located under the base frame includes an image-sensing element and at least one sensor. The sensor magnet is mounted peripherally to the lens module, and has magnetic lines parallel to the optical image-capturing axis, such that a magnetizing surface of the sensor magnet can face downward to align the sensor on the external circuit. Thereupon, the lens module can be controlled to displace along an optical image-capturing axis in a closed-loop manner.Type: ApplicationFiled: June 30, 2020Publication date: October 22, 2020Applicant: PowerGate Optical Inc.Inventors: Ying Chun Huang, Yu Chia Chen, Hsieh Jen Chuang, Te Pao Ho, Shih Chan Wen

Publication number: 20200166771Abstract: A lens driving device having an OIS system comprises a movable part equipped with a lens, a fixed part and a driving system for moving the movable part to relative to the fixed part. A plurality of notches are furnished on a frame of the movable part. Each notch extends downward from an upper surface of the frame that, a bottom of the notch is the location where a damping medium is applied. A needle of a damper applying equipment can pass through the notch in a top-to-bottom manner and apply damping medium at the bottom of the notch. In addition, medium curing equipment can apply curing light directly from the top side of the lens driving device for curing the damping medium. Not only the operations for applying and curing the damping medium can be performed in a top-and-down manner and thus decreasing the manufacturing time, but also the placement of the production space between the production trays can be reduced and thus increasing the manufacturing batch.Type: ApplicationFiled: November 19, 2019Publication date: May 28, 2020Applicant: PowerGate Optical Inc.Inventors: Ying Chun Huang, Yu Chia Chen, Hsieh Jen Chuang, Te Pao Ho
