  • Patent number: 10611031
    Abstract: A robot system 1 including: a robot; a control device which controls the robot; an elongated member attached to a distal end of the robot; a light projection unit attached to one end of the elongated member for emitting light in a longitudinal direction of the elongated member; a plurality of light reception units, arranged at the other end side of the elongated member, configured to receive the light emitted by the light projection unit; and a timer configured to measure time that is necessary for one of the light reception units to receive the light twice, where the control device controls the robot so as to slightly move a proximal end portion of the elongated member in a vibration movement direction of a distal end portion of the elongated member, based on the measured time and an order of light reception by the light reception units.

  • Patent number: 10005148
    Abstract: A chuck device capable of efficiently changing a welding tip and nozzle. The chuck device includes a rotatable chuck base, an engagement part fixed to the chuck base so as to rotate integrally with the chuck base and can engage an engagement surface of the welding tip, the engagement part allowing the welding tip to rotate with the chuck base when the chuck base is rotated while engaged with the engagement surface, and a plurality of fingers provided to the chuck base to be openable and closable and can hold the welding tip and the nozzle, the plurality of fingers being capable of moving in directions approaching and separating from the engagement part.

  • Patent number: 9827671
    Abstract: A teaching operation supporting apparatus includes a teaching jig which makes, when a mold is stationary, tentative teaching points by touching up a groove more than once while moving along the groove and which is attached to a robot, a coordinate value calculating unit for calculating coordinate values of actual robot teaching points corresponding to the respective tentative teaching points, based on the distance between a grasping position and the bottom end of the string-like workpiece, and coordinate values of the tentative teaching points, and a speed calculating unit for calculating a lowering speed of the robot for each of portions between adjacent ones of the robot teaching points, based on distances between adjacent ones of the robot teaching points, horizontal distances between adjacent ones of the tentative teaching points corresponding to the respective robot teaching points, and the constant speed of the mold.

  • Patent number: 9687985
    Abstract: The robot hand of the present invention comprises: a first abutting part which projects from a main body part in Z-direction, and has a first abutting surface against which a first surface of the workpiece abuts; second and third abutting parts which extend from the main body part, and against which the second and third surfaces of the workpiece abut respectively; and a suction member which is attached to the main body part so as to hold by suction the first surface. The suction member is deformable into an elongated shape where the suction surface is located in front of the first abutting surface in Z-direction, and into a contracted shape where the suction surface is located in back of the first abutting surface in Z-direction.

  • Publication number: 20170043477
    Abstract: A robot system includes a first robot for operation to which a work tool is attached, a second robot for delivery to which a hand is attached, a first visual sensor attached to the first robot, a first control device for controlling the first robot, and a second control device for controlling the second robot. The first control device detects the position of a workpiece when an operation is performed based on the image captured by the first imaging device. The second control device includes a second correction unit for calculating the amount of correction in the second robot which relates to a deviation of the position of the workpiece relative to the hand, based on the position of the workpiece which is acquired from the first control device.
