  • Patent number: 7062831
    Abstract: A more reliable and fool-proof method and apparatus for assembling an article of assembly (e.g. with predetermined screw torque requirements) in which the article of assembly has multiple fastening locations. The method comprises holding the article of assembly fixed while providing at least two different types of targets fixed relative to the article of assembly that correspond to the individual fastening locations. Fasteners are fastened into the article of assembly at the fastening locations. When fastening is occurring at one of the fastening locations, one of the targets is being sensed. Based on the target sensed, a target output is generated that differentiates between different types of targets thereby indicating fastening location of the fastening tool. The electronic target output is used for electronic control such as for stopping a conveyor to keep the article of assembly at an assembly station until the fastening operations have been completed.

  • Patent number: 6981311
    Abstract: A system and method for precision fastening of a fastener. The fastening system includes a motor and a sensor that provides a feedback signal from the motor to a controller. The controller compares the feedback signal to a threshold value to determine if an error condition exists. If the error condition exists, the controller oscillates a rotor to the motor between a first and a second position. In one construction, a resolver provides a signal to the controller representing a position of the oscillating rotor. The oscillating rotor vibrates the housing, thereby alerting an operator of the error condition. In one construction, the fastener device can alert the operator that the fastener is not tightened to a proper torque, and that the fastener is not rotated through a proper angle of rotation.

    Abstract: An intermittently rotated rotary mounting section 1 of a component mounting apparatus has a driver 15 at its upper part for driving the motors 11 of each of a plurality of mounting heads 10 arranged on the periphery of the rotary mounting section. A controller is built in a stationary part of the apparatus, from which power and control signals are input to the rotating driver 15. The driver 15 is formed in an annular shape, and includes a plurality of motor driver mounting plates 30, to which motor drivers 24 for controlling power supply to each motor 11 are attached. The motor driver mounting plates 30 are arranged radially around the rotation axis of the driver 15 with their planar surfaces in parallel to the rotation axis.

  • Publication number: 20010025412
    Abstract: A contact processing station with a mechanical press for the securing of a contact to a cable has a first cheek plate and a second cheek plate controlled by a drive. The first or second cheek plate is spring mounted. An elastically deformable element, for example a connecting rod capable of deformation or a spring, is available for the spring mounting. During the crimping process, the elastically deformable element is increasingly deformed until the force acting on the contact has reached a maximum whereby the force acting on the contact increases continuously with increasing deformation of the elastically deformable element. The spring constant of the elastic element is set so soft that the force with which the contact is compressed onto the cable is almost independent of fluctuations in the wire thickness.

  • Patent number: 6293006
    Abstract: A method of controlling a mounting unit having a shaft operated under servo control using a current driven actuator, comprises the steps of detecting interrruption of the servo control, and switching from a positioning control mode to a constant current control mode for supplying an constant amount of current to the shaft actuator to suspend the shaft. In an embodiment the method further includes engaging a gripping device, for holding the shaft, so as to keep the shaft from free-falling when interruption of the servo control is detected, and maintaining the constant current control mode at least until the gripping device grips the shaft. Still further, the current control mode optionally includes the steps of maintaining the supply of the constant amount of current for a predetermined period of time, and disengaging power supplied to the actuator after the predetermined period of time has elapsed.

  • Patent number: 6282779
    Abstract: In a component mounting apparatus, a component (8) is held, positioned and mounted at a predetermined position of a member (4) to be mounted. After the component (8) is mounted to the member (4), a component holding member (5) is raised by a distance corresponding approximately to a push-in amount by which the component holding member (5) has been moved down to mount the component, then stopped to retain the component (8), is kept in this state while retaining the component for a fixed time, and is raised again to a predetermined position.

  • Patent number: 6240633
    Abstract: A method for manufacturing an electronic device includes placing a plurality of components on a printed wiring board (204), detecting a defect in a component (210) and, in response, producing a defect indication including a defect location on the printed wiring board. Subsequently, additional components are placed on the printed wiring board (220) but placement of all additional components having a location which has a predetermined relation with the defect location is suspended. The defective printed wiring board may then be repaired by a technician who subsequently places the additional components over the defect location. This reduces the need to apply a large amount of heat to the printed wiring board to remove subsequently placed components such as radio frequency shields. This further reduces the possibility of additional defects occurring during repair.

  • Patent number: 5898986
    Abstract: To align an aperture (16) in a nut (12) with a hole (18) in a threaded stud (14), the nut (12) is rotated on the stud (14) to move the aperture (16) over the hole (18). Light is projected into the aperture (16) as the aperture (16) approaches the hole (18). The light is sensed when it projects from the aperture (16) through the hole (18) upon movement of the aperture (16) into alignment with the hole (18). Rotation of the nut (12) is stopped in response to sensing of the light.

  • Patent number: 5692870
    Abstract: An apparatus is provided for inserting workpieces such as electrical components into a workpiece holder. The apparatus includes a housing with push pins mounted on a press plate for engaging and inserting the workpieces into receptacles in the workpiece holder. The pins are mounted in such a manner that if the entire housing is pushed downward in the direction of the exposed pin shafts and perpendicular to the plane of the bottom surface of the press plate, and if a given pin shaft encounters a restrictive force greater than or equal to a predetermined safe resistance, that pin shaft will be allowed to travel upward vertically through the plate frame. This escape release feature thus has the effect of a vertical "clutch," preventing damage to the pins, the loading plates, and the components whenever the pin shaft encounters excessive resistance.

  • Patent number: 5637968
    Abstract: A method and apparatus for correcting torque overshoot in power tools wherein torque per angle rate is sensed on each rundown and the speed of the tool is automatically adjusted to maintain torque accuracy on higher torque rate joints while maintaining speed on lower torque rate joints, automatically minimizing tool heating and maximizing job rate. In the setting of threaded fasteners, joint rates are defined as high (hard), medium or low (soft). Two torque points are defined, a first torque point and a second torque point, which are percentages of the target torque, for example 25% and 50% respectively. Two angle values are defined corresponding to the number of degrees of tool spindle rotation measured along the portion of the torque/angle curve between the first torque point and the second torque point on typical linear hard and medium joints.
