  • Publication number: 20250131553
    Abstract: Since defect areas in collected hydro turbine defect images account for a small proportion and there is a significant color difference between surrounding background and defects, which creates too much redundant information and greatly affects detection speed, a method for detecting defects in a hydro turbine top cover based on an improved YOLOv8 model involves first cropping collected defect images to obtain cropped images, then expanding the cropped images by image enhancement techniques such as image flipping and image blurring to obtain a training dataset. A defect detection network based on YOLOv8-CBAM is constructed and trained to generate a defect detection model for detecting the defects in the hydro turbine top cover. The method achieves high precision in defect detection for the hydro turbine top cover.

  • Publication number: 20250128435
    Abstract: The present invention discloses a transfer method of thin wafer. For thin wafers with different thicknesses, in different transfer stages, a Bernoulli manipulator uses different gas flow rates, so that the problem of chipping of wafers during transfer is solved. Specifically, in a process of moving a wafer out of a wafer cassette, a Bernoulli manipulator uses a small gas flow rate, so as to reduce the suction force on the wafer and weaken warping deformation of the wafer, thereby reducing the risk of cracking or chipping in the process of moving the wafer out of the wafer cassette; after the wafer is moved out of the wafer cassette and in a process of transferring same to a processing chamber, the Bernoulli manipulator uses a large gas flow rate, so as to increase the suction force on the wafer, thereby ensuring the wafer can be stably suctioned on the Bernoulli manipulator during transfer, and avoiding wafer slipping.
