Title: Innovations by Ryuji Haraguchi: A Pioneer in Substrate Gripper Technologies
Introduction
Ryuji Haraguchi, an accomplished inventor based in Fujisawa, Japan, has made significant contributions to the field of substrate handling technologies. With a total of two patents to his name, Haraguchi has demonstrated his expertise in engineering solutions that enhance the efficiency of processes such as spin drying.
Latest Patents
One of Haraguchi's notable inventions is a substrate gripper device specifically designed for spin drying. This innovative device features a rotatable substrate stage equipped with multiple fixing fingers that are vertically mounted on the outer edge. Each fixing finger has a horizontal substrate rest that effectively holds the outer edge of the substrate. Additionally, the device includes swing fingers that are angularly movably supported on the fixing fingers, which work in tandem to vertically grip the substrate. The swing fingers are normally biased towards the fixing fingers by helical springs, ensuring a secure grip. To enable the opening of the swing fingers, a series of vertically movably disposed opening pins are utilized, which can be moved upwardly to counteract the biasing forces of the springs. This mechanism enhances the overall functionality of the substrate handling process during spin drying operations.
