Patent number: 9120221Abstract: Provided is a robot cell apparatus in which a cooperatively operable area for a pair of robot arms can be widened and which has an excellent workability. The present invention includes a table with a plane having a quadrangular shape in plan view, a workpiece being placed on the plane. Proximal ends of robot arms are respectively fixed to two corners at diagonal positions among four corners of the plane of the table. A cooperatively operable area in which the pair of robot arms are cooperatively operable is formed in a space above the plane of the table.Type: GrantFiled: May 16, 2011Date of Patent: September 1, 2015Assignee: CANON KABUSHIKI KAISHAInventors: Mikio Nakasugi, Mahito Negishi, Masaichi Sato, Ken Meisho, Yuji Matsuo

Patent number: 9027231Abstract: To enable positioning a robot arm and a workpiece with high accuracy while reducing vibrations of a camera. According to the claimed invention for this purpose, a robot station 100 includes a pedestal 103 to which robot arms 101 and 102 are fixed, a camera 106 which images an area including a working area 209 of the pedestal 103, and a booth 104 to which the camera 106 is fixed. The pedestal 103 is fixed to a floor surface, and the booth 104 is fixed to the floor surface without contacting the pedestal 103. The booth 104 is formed in the shape of a rectangular parallelepiped having a short side parallel to a workpiece conveying direction T and a long side perpendicular to the workpiece conveying direction T in a plan view.Type: GrantFiled: June 22, 2011Date of Patent: May 12, 2015Assignee: Canon Kabushiki KaishaInventors: Toshihiko Mimura, Yuichi Someya, Yuji Matsuo, Mikio Nakasugi, Ken Meisho, Masaichi Sato, Mahito Negishi

Patent number: 8182197Abstract: In a gripping device, a displacement-type force sensor is provided on a side of a driving mechanism opposite fingers to which the driving mechanism is connected to form a grip section. The driving mechanism is supported on a housing with an elastic member being disposed therebetween at a position closer to the fingers than the center of gravity of the grip section.Type: GrantFiled: October 26, 2009Date of Patent: May 22, 2012Assignee: Canon Kabushiki KaishaInventor: Ken Meisho

Publication number: 20110258847Abstract: A robotic cell enables a robotic station to be downsized and both high maintainability and high rigidity to be attained. To this end, the robotic cell for assembling parts by using multiple robots includes multiple booths for housing multiple trestles, on each of which a pair of robotic arms are mounted, with the trestles adjoining one another. Each trestle has an opening portion on one side surface thereof, through which a power controller box is carried in and out. To compensate for a decrease in rigidity of the trestle due to the opening portion, a connecting member is used for coupling two trestles adjacent to each other across the respective booths. Both end portions of each connecting member are fastened to the both trestles with screws, respectively.Type: ApplicationFiled: April 4, 2011Publication date: October 27, 2011Applicant: CANON KABUSHIKI KAISHAInventors: Ken Meisho, Mikio Nakasugi, Mahito Negishi, Yuji Matsuo

Patent number: 7915787Abstract: A cylindrical piezoelectric element is arranged to share an axis with a cylindrical vibrator having different diameters at central and end portions to fix the vibrator forming a gap at the central portion. Vibration voltages are applied across first electrodes on the piezoelectric element and the vibrator, namely, a second electrode, to vibrate the vibrator and bring a wave front of a traveling wave into contact with a tubular member, i.e., a supporting member fitted to the vibrator. Friction at a contact portion of the vibrator moves a mover including the vibrator and the piezoelectric element in an axial direction of the tubular member. By amplifying the vibration amplitude using the vibrator provided separately from the piezoelectric element, a small actuator capable of performing high-speed driving is realized.Type: GrantFiled: July 8, 2008Date of Patent: March 29, 2011Assignee: Canon Kabushiki KaishaInventors: Mahito Negishi, Takao Yokomatsu, Ken Meisho, Seiichi Hata, Akira Shimokohbe, Dongming Sun, Sheng Wang
