Publication number: 20240091838Abstract: A forming method of a processing curve in a stamping process is provided. The method includes the following steps. A plurality of processing curves are established, and an optimization target is set for the processing curves according to material characteristics of a workpiece, process requirements and a finished product CAD file. At least two of the processing curves are selected and superimposed to form a basic forming curve, wherein each subsection of the basic forming curve corresponds to a selected processing curve. Whether the selected processing curve in each subsection of the basic forming curve matches the optimization target is determined.Type: ApplicationFiled: November 28, 2022Publication date: March 21, 2024Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Po-Huang SHIEH, Hsuan-Yu HUANG, Ming-Cheng TSAI, Yi-Ping HUANG

Publication number: 20190122326Abstract: A carrier includes at least one sucking member, a pressure-differentiating device, an optical unit and an image-capturing unit. The at least one sucking member, made of a flexible transparent material, has a plurality of micro holes extending in a first direction by penetrating through two opposing surfaces of the at least one sucking member. The pressure-differentiating device, connected with the at least one sucking member, is to have the at least one sucking member to perform a pressure-differentiated suction upon a workpiece. The optical unit is to capture an image of the workpiece through the at least one sucking member and to refract/reflect the image by an image-forming angle. The image-capturing unit is to capture and further output the image refracted/reflected by the optical unit in a real-time manner.Type: ApplicationFiled: December 13, 2017Publication date: April 25, 2019Inventors: YI-PING HUANG, HSUAN-YU HUANG, PO-HUANG SHIEH, MING-CHENG TSAI

Patent number: 10260870Abstract: An on-line measuring system, a datum calibrating method, a deviation measuring method and a computer-readable medium are provided. The datum calibrating method includes following steps. A work piece is scanned by a scanning unit to obtain a global point cloud data. A local CAD data of the work piece is obtained according to a predetermined range. A local CAD geometric feature of the local CAD data is obtained. A local point cloud data of the global point cloud data is obtained according to a local range corresponding to the predetermined range. A local scanning geometric feature of the local point cloud data is obtained. The local scanning geometric feature and the local CAD geometric feature are compared to obtain at least one spatial freedom limit. A system basis is obtained according to six spatial freedom limits, if the number of the at least one spatial freedom limit reaches six.Type: GrantFiled: December 27, 2017Date of Patent: April 16, 2019Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Po-Huang Shieh, Po-Nien Tsou, Wei-Chieh Chang, Ming-Cheng Tsai

Patent number: 8688274Abstract: A robot positioning method includes the following steps. A optical sensing device is configured at a front end of a robot. Then, the optical sensing device captures a calibration plate image, and a relative position of the optical sensing device with respective to a calibration plate is calculated according to a Bundle Adjustment. A robot calibration method includes the following steps. An optical sensing device is driven to rotate around a reference axis of a calibration plate, so as to calculate a translation matrix between the calibration plate and the robot, and the optical sensing device is driven to translate along three orthogonal reference axes of the calibration plate, so as to calculate a rotation matrix between the calibration plate and the robot.Type: GrantFiled: January 25, 2011Date of Patent: April 1, 2014Assignee: Industrial Technology Research InstituteInventors: Po-Huang Shieh, Shang-Chieh Lu, Bor-Tung Jiang, Kuo-Tang Huang, Chin-Kuei Chang
