    Abstract: A fitting apparatus includes a robot arm having, at the forward end thereof, a gripper for holding a workpiece, a force detector for detecting a force and moment received by the workpiece held by the gripper, and a controller for controlling an operation of the robot arm. The controller includes a motion command generating unit for generating an operation command to fit two workpieces to each other, and an operation command correcting unit for correcting the operation command so as to correct the position of the gripper in a direction perpendicular to the fitting direction and the orientation of the gripper around an axis perpendicular to the fitting direction until the detected force and moment become less than or equal to a threshold value, based on either maximum values of the force and moment detected by the force detector while the two workpieces are in contact with each other or the force and moment detected by the force detector when the two workpieces first come into contact with each other.

  • Patent number: 7077446
    Abstract: An articulated finger unit has a two-jointed structure comprising a joint portion on a finger base side, a finger base portion, a joint portion on a fingertip side, and a fingertip portion; the joint portion on the finger base side has a drive-side bevel gear fixed to a rotational output shaft of an actuator, a driven-side bevel gear coaxially fixed to a joint portion that is perpendicular to the rotational output shaft, and a connecting member wherein an annular boss is fixed to the driven-side bevel gear and wherein a tip portion extends in a fork shape; and a cover on the finger base side is connected to the connecting member. A rotation of the rotational output shaft is converted to rotational movement of the joint shaft by way of a pair of bevel gears, and the connecting member fixed to the joint shaft turns right and left at an angle of 90° or more about the joint shaft. The finger unit suitable for use in a robot hand that moves at high speed and with precision can be realized.

  • Patent number: 6986636
    Abstract: A device for positioning disk-shaped objects (1) to inspect the front and rear sides of disk-shaped objects and to reduce the negative effect of large-area contact between the holder and the disk-shaped object. The device comprises a rotatable table (24) which can be adjusted in the x-y direction in an adjustment plane and is intended to accomodate a platform (3). A fork-shaped frame (8) is mounted on the platform so as to be rotatable about an axis of rotation which is aligned perpendicular to the surface of the platform (3) and the angle of tilt of which can be set relative to the adjustment plane. At its fork ends, the fork-shaped frame (8) has another axis of rotation which is aligned perpendicular to the axis of rotation of the fork-shaped frame (8) and about which a frame-shaped object holder (9) is mounted so as to be rotatable in the fork-shaped frame (8) for the purpose of turning the object.

  • Patent number: 6918735
    Abstract: The invention relates to a holding device for wafers in an arrangement for wafer inspection, comprising two grippers (11, 12), each of which, in the closed state of the holding device (8), encloses a subsection of the wafer circumference and which are connected to a drive device (27) and, when the latter is driven, the grippers (11, 12) move away from each other for the purpose of opening the holding device (9) and move toward each other for the purpose of closing the holding device (8), and a holding arm (13), on which the two grippers (11, 12) are pivotably mounted. In this case the holding arm (13) is mounted such that it can rotate about an axis (A) which lies substantially in the plane covered by the wafer (W), so that after a rotation through 180° about the axis (A), a wafer (W) held between the grippers (11, 12) has been turned.

  • Patent number: 6886231
    Abstract: An apparatus and method for mounting a valve stem to the rim of an automotive vehicle wheel includes rims being supplied in series by a conveyor to a gauging station where the type and/or size of the rim and the location and alignment of an aperture for receiving the valve stem is determined by a machine vision system. An electronic control system directs a robotic manipulator to grasp either the valve stem or the rim, move the valve stem or the rim to a mounting station, position the valve stem or the rim with respect to the other such that the aperture in the rim is in coaxial alignment with the valve stem, and insert the valve stem through the aperture in the rim. If necessary, a power-actuated nut runner, mounted on the robotic manipulator or adjacent the mounting station, is used to tighten a nut over the valve stem.

  • Patent number: 6877215
    Abstract: A compliance mechanism for manipulating a control object by an end effector supported by a robotic arm. The robotic arm is supported by a combination of linear slides for two-axis freedom of movement. A locking arm is attached to the robotic arm and the locking arm is moveable between a locked and an unlocked position. The locking arm is biased in the locked position to restrict movement of the robotic arm along the two axes. A plunger extends adjacent the end effector. Upon engagement with an alignment feature associated with the control object, the plunger moves the locking arm from the locked to the unlocked position, thereby introducing compliance along the two axes manipulation of the control object.

  • Patent number: 6848168
    Abstract: Method for controlling installation of a head stack assembly in a disc drive. The head stack assembly is aligned in a head stack installation tool. A base deck assembly is advanced to the head stack installation tool, the base deck assembly having a post supporting a tolerance ring. A robotic assembly is dispatched to pick and press the head stack assembly onto the tolerance ring and post while mechanical resistance and distance traveled parameters by the head stack assembly are measured. The installation is aborted or completed in relation to the mechanical resistance encountered and the distance traveled, thus allowing use of minimum and maximum force thresholds with respect to insertion distance and assuring correct installation of the head stack assembly.
