  • Patent number: 7566198
    Abstract: An industrial robot may include a main body part and an arm part including a first arm, a second arm and a hand arm. The main body part is provided with a first turnable shaft for performing an expansion-contraction operation of the arm part, a second turnable shaft which is disposed within the first turnable shaft for changing an expansion-contraction direction of the hand arm together with the first arm, a first sensor mechanism including a first sensor for detecting a home position of the second turnable shaft, a second sensor mechanism provided in the second turnable shaft and which includes a second sensor for detecting a relative home position between the second turnable shaft and the first turnable shaft, and a rotary joint which is connected with the second turnable shaft and is electrically connected with the second sensor.

  • Publication number: 20090084215
    Abstract: An industrial robot for conveying a conveying object may include a hand having a mounting part, an articulated arm part having at least a hand holding arm which is extended and folded when the conveying object is conveyed, a main body part which turnably holds the articulated arm part, and a cam member which is provided in the hand holding arm and which is formed with a cam face with which the holding part is abutted and which is relatively turned with respect to the hand around a turning center of the hand with an extending and folding operation of the articulated arm part. The cam face is formed so that the holding part is retreated from the conveying object before the conveying object is conveyed and, when the conveying object is conveyed, the holding part is moved in a direction to hold the conveying object.

  • Publication number: 20080304942
    Abstract: An industrial robot may include a robot hand structured to mount a transfer object, a multi-joint arm section having at least two arms including a robot hand supporting arm structured to support the robot hand to be rotatable; and a main section structured to support the multi-joint arm section to be rotatable. The robot hand may include a grasping part structured to contact and grasp the transfer object and a biasing member structured to bias the grasping part in a direction for grasping the transfer object. The robot hand supporting arm may include an eccentric member fixed to the robot hand supporting arm at a position being eccentric from a turning center of the robot hand in relation to the supporting arm.

  • Patent number: 6739638
    Abstract: Relating to improvement in a hand of an apparatus for taking out a workpiece such as liquid crystal glass from a cassette and carrying it to a predetermined position, and aiming at reducing a weight of an arm portion for holding the liquid crystal glass and a quantity of deflection. A workpiece holding portion of the hand for holding a workpiece such as liquid crystal glass is formed by a horizontal holding arm (5) extending in the horizontal direction and consisting of a carbon fiber material, the horizontal holding arm (5) has a horizontal arm portion (7) opposed to the workpiece and at least one bent portion (6) being bent in a direction crossing the horizontal arm portion (7), and a surface of a corner portion (5d) on the border between the bent portion (6) and the horizontal arm portion (7) is rounded.

  • Patent number: 6195454
    Abstract: A component mounting head has a holding unit including, for example, a suction nozzle for holding a component such as a TCP, and a camera. The camera simultaneously detects the position of a target reference mark and the TCP. An angle adjusting mechanism adjusts an angle of the holding unit based on a holding angle error, and a head moving mechanism moves the component mounting head based on the position of the target reference mark and the TCP, thereby positioning the TCP to the target position.

  • Patent number: 5960534
    Abstract: An electronic-part surface mounting apparatus includes an S-Z shaft vertically movable with respect to the mounted surface of a printed circuit board on which mounted parts such as electronic parts are mounted, and rotatable in a plane parallel to the mounted surface; an arm member revolving around the S-Z shaft; a plural number of Z-shafts, supported by the arm member, being vertically movable with respect to the mounted surface; cam unit revolving around the Z-shafts to cause the Z-shafts to individually move in a reciprocating manner; attraction/mounting unit operating such that at a position where the Z-shafts come nearest to the mounted surface, the attraction/mounting unit releases the mounted part from its seizure by the absorption nozzle attached to the lower end of the Z-shaft and mounts the mounted part on the mounted surface.
