Means To Apply Magnetic Force Directly To Position Or Hold Work Part Patents (Class 29/744)
  • Patent number: 4283847
    Abstract: An apparatus and method for assembling integrated circuits to a printed circuit board wherein integrated circuits with protective carriers are selectively dispensed from a rotary magazine, are removed from the carriers and positioned by the leads on magnetic holders on a continuous conveyor which moves the integrated circuits, thus mounted on the holders, to a lead-forming and trim assembly wherein the leads are bent downwardly and outwardly to form feet and trimmed. Thereafter the integrated circuits are moved, thus mounted on the holders, to a flux-applying assembly wherein flux is applied to the lead feet, then to a solder-applying assembly wherein solder is applied to the lead feet, and then to a program activated X-Y axis table which mounts the printed circuit board. The integrated circuits, with tinned leads, are transferred through magnetic fingers to the printed circuit board wherein electrodes solder the leads to pads on the Board.

  • Patent number: 4238658
    Abstract: What is proposed is a method of assembling nonmagnetic current-conducting components into units along an axis of assembly. The assembly is arranged under the effect of electrodynamic forces formed by the interaction of a primary alternating magnetic field directed along the axis of assembly and a secondary magnetic field. The components to be assembled are placed in the primary magnetic field so that the areas covered by the contours of the currents induced in these components by the magnetic field are located in planes approximately perpendicular to the axis of assembly; and in each adjacent pair of components to be assembled the regions covered by the contours of the induced currents at least partially overlap each other.

  • Patent number: 4196511
    Abstract: The device or apparatus for assembling banks of battery electrodes comprises a bed which mounts feeders with electrode-containing holders, and the feeders incorporating a mechanism for maintaining automatically the upper level of the electrode pile in the holders. Disposed above the feeders is an assembling mechanism comprising a shaft, one end of which is connected to a drive ensuring its vertical reciprocating motion in alternation with a full revolution around its axis, whereas the other end of the shaft carries radially-mounted grips made with a provision for being disengaged at a certain working stroke of the assembling mechanism by a readjustable kinematic linkage which can disengage part of the grips during the preset working stroke of the assembling mechanism.

  • Patent number: 4144637
    Abstract: A device for making sets of nonmagnetic current-conducting components on a base component in arrangements constituting identification patterns of the set being made. The device comprises a source of an alternating magnetic field, feeding the components arranged into a set as well as the base components into the working area of the magnetic field, and extractor means for removing the complete sets of components from the working area of the magnetic field. Each base component is a substrate comprising essentially a dielectric plate, fitted with inserts made from a current-conducting material and having cross section configurations similar to the cross-sectional shapes of the components being arranged into a set. The inserts arranged to determine the identification patterns of the set being made.

  • Patent number: 4017956
    Abstract: Apparatus for manufacturing lamp envelopes for axial-geometry incandescent lamps comprises a plurality of magazines for receiving stacks of lamp envelope components and a transport moveable with respect to the magazines and having component-receiving platforms alignable with ends of the magazines. The platforms are supported on rotatable hubs and the hubs have axial bores through which components are pushed onto the platforms by pusher means. The hubs are supported at one end of a transport arm, the other end of the arm being supported for pivotal movement about an axis parallel to the axis of rotation of the hubs so that the transport arm may be moved relative to the magazines. An arrangement of holding magnets and spring-biased slotted plates associated with the platforms controls the holding and release of components.
