Publication number: 20210387287Abstract: A laser processing system for a glass workpiece comprises a frame with a first laser module thereon, a modifying device, and a blanking device. The blanking device comprises a second laser module, a hollow support element, a clamping module disposed on the frame, a heater disposed on the hollow support element, and a cooler connected to the clamping module. A method adapted to the system comprises a modifying process, a determining process, and a blanking process. In the modifying process, a first laser beam is irradiated to the glass workpiece along a processing contour line to intermittently modify the glass workpiece. According to the determining process, the blanking process is processed to have a crack being generated in a modified portion of the glass workpiece, wherein the crack divides the glass workpiece into an outer area and an inner area, and changes a temperature of the glass workpiece to have the glass workpiece being deformed, so that the outer area and the inner area are separated.Type: ApplicationFiled: November 25, 2020Publication date: December 16, 2021Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Mao-Chi LIN, Shao-Chuan LU, Pin-Hao HU

Publication number: 20160147214Abstract: A three-dimension laser processing apparatus including a laser source, a zoom lens set, a scanning mirror module, a visual module unit and a control unit is provided. The laser source provides a laser beam. The zoom lens set and the scanning mirror module are both located on the transmitting path of the laser beam. The visual module unit has a visible area. The control unit is electrically connected with and adjusts the zoom lens set and the scanning mirror module to make the laser beam focused on a plurality of reference surfaces in a three-dimension working space and make a plurality of positions of an image in the three-dimension working space focused on a center of the visible area correspondingly through the zoom lens set and an image lens set of the visual module unit. Besides, a positioning error correction method is provided.Type: ApplicationFiled: November 19, 2015Publication date: May 26, 2016Inventors: Shao-Chuan Lu, Yu-Chung Lin, Jie-Ting Tseng, Min-Kai Lee

Patent number: 7847239Abstract: A calibration strip and a laser calibration system using thereof are disclosed. The calibration strip is comprised of: a substrate; and a light impermissible layer, having a calibration pattern formed thereon while being formed on the substrate. The light impermissible layer is an opaque layer, being formed on the surface of the substrate by coating, electroplating or adhering. The substrate, manufactured by the principle for enabling the color or brightness of the substrate to have high contrast comparing with those of the light impermissible layer, can be a structure of a layer of transparent material and a light source; a layer of transparent material and a backlight source; or a metal film having a reflective layer formed thereon.Type: GrantFiled: March 25, 2008Date of Patent: December 7, 2010Assignee: Industrial Technology Research InstituteInventors: Shao-Chuan Lu, Min-Kai Lee, Sung-Ho Liu
