Patent number: 9272413Abstract: A conveying system according to an embodiment includes a robot and a controller. The controller includes a switching unit. The robot includes an arm unit formed of a hand and a plurality of arms connected rotatably with respect to one another, and a base unit. An arm on a rear end side is connected to the base unit rotatably about a rotation axis, and the hand is rotatably connected to an arm on a front end side. The switching unit switches cylindrical coordinate control for controlling the arm unit such that a trajectory of the hand overlaps with any one of lines radiating from the rotation axis and rectangular coordinate control for controlling the arm unit such that the trajectory of the hand overlaps with none of the lines at a predetermined timing.Type: GrantFiled: November 29, 2012Date of Patent: March 1, 2016Assignee: KABUSHIKI KAISHA YASKAWA DENKIInventors: Masatoshi Furuichi, Yoshiki Kimura, Tomohiro Matsuo, Yoshihiro Kusama

Publication number: 20130039730Abstract: A robot includes a rotating electrical machine and a brake. The brake is configured to restrict rotation of the rotating electrical machine. The brake includes a brake plate, a plurality of pressing members, at least one biasing member, and an electromagnetic coil. The brake plate is configured to rotate integrally with a shaft of the rotating electrical machine. The plurality of pressing members are movable toward the brake plate and include a first pressing member and a second pressing member. The at least one biasing member is configured to bias the first pressing member and the second pressing member toward the brake plate using mutually different biasing forces. The electromagnetic coil is configured to, when current is on, electromagnetically attract the first pressing member and the second pressing member against the biasing forces of the at least one biasing member.Type: ApplicationFiled: July 26, 2012Publication date: February 14, 2013Applicant: KABUSHIKI KAISHA YASKAWA DENKIInventors: Satoshi SUEYOSHI, Kentaro TANAKA, Yoshihiro KUSAMA, Tomohiro MATSUO

Publication number: 20110236162Abstract: A processing-object-supporting mechanism includes at least three devices each including a lift pin, a motor, and a drive controller. The lift pin contacts a processing object to support the processing object. The processing object is transferred between a conveying arm and the processing-object-supporting mechanism. The motor lifts and lowers the lift pin. The drive controller is configured to control the motor. The drive controller of each of the at least three devices is configured to control the motor of each of the at least three devices independently.Type: ApplicationFiled: February 24, 2011Publication date: September 29, 2011Applicant: KABUSHIKI KAISHA YASKAWA DENKIInventors: Toru Shikayama, Tadataka Noguchi, Akihito Toyota, Yoshihiro Kusama

Patent number: 7980611Abstract: A substrate holding apparatus includes a base plate with a two-pronged portion, a holding plate arranged above the base plate, a driving portion provided therebetween, a holding portion formed by a tip end of the two-pronged portion and a tip end of the holding plate, and a guide portion provided at the tip end of the two-pronged portion for guiding a part of the substrate. The driving portion includes an urging means for always urging a basal end side of the holding plate upward, an electric magnetic portion for drawing the holding plate toward the base plate, and a bearing portion arranged at on the tip end side of the base plate. The guide portion has a guide groove which comes into contact with a part of a periphery of the substrate.Type: GrantFiled: January 23, 2009Date of Patent: July 19, 2011Assignee: Kabushiki Kaisha Yaskawa DenkiInventors: Hideharu Zenpo, Hideo Yamamoto, Toshiyuki Harada, Yoshihiro Kusama, Katsuya Okumura

Patent number: 7950890Abstract: A vacuum robot includes an arm portion on which a work is to be disposed under a reduced pressure environment and a motor portion for rotatably driving the arm portion, the vacuum robot being configured to transfer the work by causing a rotational movement of the arm portion by the motor portion. The motor portion comprises a rotor portion connected to the arm portion, a stator portion disposed at an external periphery of the rotor portion, a housing disposed under an atmospheric pressure environment, and a thin cylindrical can disposed in an electromagnetic gap formed between the rotor portion and the stator portion and secured to the housing so that the stator portion is air-tightly encapsulated in a space formed by the housing and the can. The space is maintained in a depressurized state by a seal.Type: GrantFiled: June 1, 2007Date of Patent: May 31, 2011Assignee: Kabushiki Kaisha Yaskawa DenkiInventors: Takayuki Nakamura, Tadataka Noguchi, Yoshihiro Kusama

Patent number: 7789614Abstract: It is an object to provide an aligner for centering a wafer and adjusting an angle of a notch or the like of the wafer while gripping edges of the wafer capable of attaining a shortened takt time and miniaturization of the apparatus by employing a mechanism capable of infinite rotation without being restricted by a rotational range, by eliminating cables and/or tubes at the rotating portion. The link mechanism for causing opening and closing movements of the gripping mechanism for gripping a wafer 1 is supported via a bearing 14 with respect to the link mechanism driving portion for driving the link mechanism so that only the gripping portion and the link mechanism can be rotated.Type: GrantFiled: May 25, 2006Date of Patent: September 7, 2010Assignee: Kabushiki Kaisha Yaskawa DenkiInventors: Keisuke Yoshino, Mitsuaki Hagio, Shin Osaki, Yoshihiro Kusama
