Patent number: 10632568Abstract: Systems and methods for laser drilling provide laser beam energy modification to reduce (e.g., eliminate or minimize) back-wall strikes during laser drilling. The systems and methods modify the process laser beam energy such that a beam energy at a central region of the process laser beam is less than a beam energy at an outer region of the process laser beam. In one example, the modified process beam has zero beam energy at the central region, thereby providing a “donut mode.” The laser beam energy modification may be achieved by detuning a fiber coupler in the Z axis such that laser energy is coupled into a cladding layer of the process fiber coupled to the laser fiber via the fiber coupler.Type: GrantFiled: June 10, 2016Date of Patent: April 28, 2020Assignee: IPG PHOTONICS CORPORATIONInventor: Steven R.

Patent number: 10632569Abstract: The present invention provides a laser cutting method, a display substrate and a display device. In the laser cutting method, the display substrate and the display device, as a cutting line is defined by two width defining dams on both sides of a region to be cut, the width of the cutting line can be adjusted by adjusting the distance between the two width defining dams. Thus, the width of the laser cutting line is controlled, and the effective use area of the substrate may be saved (and the material may be saved). Meanwhile, as the width defining dams are made of a laser reflective material, a laser beam irradiated onto the width defining dams is reflected without being absorbed by the width defining dams and thus transmitted to a corresponding region on the substrate. As a result, the generation of a carbonization region is avoided.Type: GrantFiled: May 18, 2015Date of Patent: April 28, 2020Assignee: BOE TECHNOLOGY GROUP CO., LTD.Inventors: Mingche Hsieh, Chunyan Xie, Lu Liu, Hejin Wang

Patent number: 10632570Abstract: Welding quality of a welding section W welded by laser welding is determined by acquiring an image of the welding section W and its surrounding region by means of a high-speed camera 11, analyzing, as parameters, the number of spatters P per unit length and the area of a high-luminance region in the acquired image by means of an analyzer 12, and comparing the analyzed parameters with respective comparison tables created beforehand, to determine the welding quality of the welding section Wa. Information on the welding quality of the welding section W is displayed on a monitor 13. Not only the laser welding quality of the welding section can be determined but also in-process shearing strength prediction as well as in-process fracture mode prediction can be performed, thus enabling quality control matching high-speed and high-precision laser welding.Type: GrantFiled: August 26, 2010Date of Patent: April 28, 2020Assignee: IHI INSPECTION & INSTRUMENTATION CO.

Patent number: 10632574Abstract: A method of manufacturing printed images on metal with tight bends provides for crack free edges at the tight bends, something previously unattainable in the marketplace. Specifically, prior to bending the metal, the at least coated metal (if not dye sublimated printed) is at an elevated temperature in a range of 90 to 250 degrees Fahrenheit, such as in a range of 190-200 degrees. The metal is then bent which has been found to permit self-leveling of the coating throughout the tight bend, as opposed to it being so narrow that cracking occurs.Type: GrantFiled: September 6, 2018Date of Patent: April 28, 2020Inventor: Joseph Bryan Creech

Patent number: 10632576Abstract: A method of servicing a pipe bundle or riser bundle employs a specially configured hoist having a rail that supports multiple lifts. A selected satellite pipe/conduit of the pipe bundle is both lifted and pulled horizontally in order to remove it from a plurality of supports that hold the satellite pipes together in spaced apart positions. During removal of a satellite pipe, the lifts elevate, then travel with and hold the pipe as it moves horizontally away from the bundle.Type: GrantFiled: December 22, 2017Date of Patent: April 28, 2020Inventor: Don M.
