    Abstract: A cover sheet assembling apparatus for an electronic component such as a ladder-type filter, which delivers a sheet member stepwisely by feed means, punches out a cover sheet from the sheet member with a punch and a die, and inserts the cover sheet in an opening of a case so that the lead portions of terminal plates pass through slits of the cover sheet. According to this apparatus, it becomes possible to automatically assemble the cover sheet in the case, thereby the working efficiency is highly improved.

  • Patent number: 5477597
    Abstract: The present invention provides a method and apparatus for positioning tooling with respect to a curvilinear workpiece which is curved in a first direction extending along a plane substantially perpendicular to the longitudinal axis of the workpiece and which is curved in a second direction extending along a plane to the workpiece longitudinal axis, the degree of curvature in the first direction being greater than the degree of curvature in the second direction. An illustrative example is automatic drilling, inserting and upsetting one or two piece fasteners such as exterior skin rivets on an airplane fuselage. Inner and outer positioning systems carry or support inner and outer tooling, respectively, which engage the workpiece from opposite sides thereof during tooling operations thereon.

  • Patent number: 5398395
    Abstract: Apparatus for applying a sleeve of heat-shrink material (a "band") to a container comprises a rotary drum having a plurality of upstanding heads. A web of banding material is intermittently advanced and lengths cut off, each cut length being held by fingers in the path of a gripper head mounted on the rotary drum. Each head has forward-facing vacuum port through which air is drawn on a timed basis, so that a band 30 will be picked-up and held by one side face as the gripper head passes the fingers. The resilience of the banding material allows the band partially to open out as it is transferred by the gripper head. The rotation of the drum is synchronized to advancement of the containers, so that a held band is rolled on to the top of a container, the container serving to assist in the opening-out of the band, whereat the band is released by the gripper head.

  • Patent number: 5371931
    Abstract: Software and hardware such as part feeding and assembling devices constituting a production system are simplified with the use of a plurality of processing and assembly integrated units in which processing and assembling of parts are coupled and integrated in accordance with products to be produced. The necessities for an automatic warehouse and an automated ground vehicle are eliminated by getting rid of futility of mere movements of the parts. A fundamental idea is that a production system is constructed of units in which three sections--a section for processing a raw material, a check functional section and an assembling section--are integrally combined in accordance with the products to be produced. The parts are processed, checked and assembled by single units just in time while targeting molded parts of plastic and pressed parts.

  • Patent number: 5287608
    Abstract: A tape automated bonding feeder apparatus employs a vertical carrier extraction unit to successively supply electronic circuit components to an output station from which a component is seized for placement and attachment to a circuit board. The feeder apparatus, which may be mounted on a rollable cart, includes a generally rectilinear housing on a top plate of which one or more magazines are mounted. A magazine contains a stack of circuit component carriers. The bottom of the magazine has a carrier extraction unit which controllably allows an individual component carrier at the bottom of the stack to drop away onto an underlying carrier shuttle. The carrier shuttle is supported for movement between the magazine and a lead forming unit. The lead forming unit detaches a component from the carrier and forms the leads of the excised component for mounting the component to a circuit board.

  • Patent number: 5276954
    Abstract: A slide mounter where a photographic film transparency is advanced to an operation station and is cut from a photographic film web and punch holes are punched. The cut and punched film transparency is then inserted into a slide mount at an insertion station. The punch holes are designed to cooperate with pin registrations in the slide mount to lock the film transparency in place within the slide mount. The photographic film transparency is cut from a photographic web which is supported along a support axis. The film transparency is pushed from the operation station after it is cut and punched along a push axis into the slide mount M. The orientation of the push axis and the support axis is design to accommodate exposed film where the image is 90.degree. from the normal orientation of images recorded by a photographic camera.
