Abstract: A dual lane board handling apparatus includes a first zone including first and second parallel pairs of rails extending in a first direction; a second zone including third and fourth parallel pairs of rails extending in the first direction; first tracks supporting the first and second pairs of rails so that the first and second pairs of rails can move on the first tracks in a second direction perpendicular to the first direction; a drive for moving the first pair of rails on the first tracks in the second direction such that the first pair of rails can be selectively moved between a first orientation wherein it is in alignment with the fourth pair of rails and a second orientation wherein it is in alignment with the third pair of rails; a drive for moving the second pair of rails in the second direction; and belts on the first, second, third, and fourth pairs of rails for conveying boards along the rails in the first direction.

Abstract: A drive and actuation mechanism for a component insertion machine having a lead screw mounted to a housing by a ball nut and a spline nut so as to be movable longitudinally and rotationally. The lead screw has a hollow shaft in which a push rod is disposed. An arm support is mounted to the lead screw so as to move vertically with the lead screw. An actuation arm is connected at a first bearing point to the push rod and connected at a second bearing point to the arm support. The actuation arm is driven by a crank motor, which is connected to the actuation arm at a third bearing point, to move the push rod. The ball nut and spline nut are also driven by motors to move the lead screw vertically and rotationally.

Abstract: The present invention features a pocket-sized, portable, flotation device that folds into a storage or carrying case, which is the size of a cellular phone. It can be carried upon a person in a shirt pocket or clipped to a waistline belt. The flotation device includes a life vest with a collar having separate cells, each of which is substantially sealed from adjacent cells to prevent deflation of the adjacent cells through puncture to one of the cells. The collar of the life vest inflates, cell by cell, allowing the user to position the vest over his or her head during inflation. The carrying case has a body and a detachable, arch-shaped cover, constructed so that a tether can be inserted into the cover and the device automatically activated by pulling the cover from the body. Moreover, the case includes a belt loop through which the belt of the user can be inserted. The handle can be hollow, to form a loop into which the tether (attached to the life vest itself) can be threaded.

Abstract: An apparatus is provided for receiving a molded carrier ring package and removing the electronic component from the surrounding ring while cutting and forming the leads of the component. The shear provides that leads on two opposite sides of a rectangulopiped component are cut just prior to the leads extending from the remaining two sides, during one stroke of the shear, such that the applied force required to cut all of the leads is reduced by acting on one-half of the leads at a time, and such that the applied forces are balanced on opposite sides of the component. Each of a punch and die is easily interchanged with a replacement, and a scrap remover is continuously adjustable during closing of the jaws thereof, so that it is a simple matter to change the tooling and otherwise accommodate devices of different sizes. Also, the apparatus provides for diverting the forces of the shearing and forming action from a shuttle for transporting the device so as to minimize wear and tear on it.

Abstract: The present invention is directed to a feeder cassette for feeding electronic components into a component processing unit. The cassette includes an assembly body having a plurality of slots formed on opposing interior sides thereof to form channels within the assembly body. The channels are designed to receive a plurality of components therein, preferably in pre-packed flat tubes. A leaf spring having a button projecting from the distal end of each of the fingers of the leaf spring permits only the components from a desired "activated" channel to be released. The cassette is indexed forwardly until all of the components have been released from each of the channels sequentially. The buttons of the spring fingers also serve to hold the components within the cassette if the cassette is withdrawn from the feeder unit at any time prior to fully emptying the tubes.

Abstract: The present device is directed to a nozzle tip for the head of a pick and place device for arranging electronic components as desired on a substrate. The tip permits both first and second vacuum areas to be selectively generated, thus facilitating the pick-up of components of widely varying sizes and shapes with a single tip.

Abstract: The present invention involves a method and apparatus for sequencing leadless and leaded surface mountable components, feeding them directly from a sequencer to chip placement heads, and placing them at selected locations on a circuit board. The chip carriers of an endless chain conveyor carry each component of the sequence of components to a chip placement head. Direct supply from a sequencer having the chip carriers and a series of individual programmably controlled dispenser heads provides for quick and flexible variation of the input sequence without manual intervention. A plurality of the chip placement heads are mounted on a turret assembly to facilitate continuous unloading of the chip carriers and orienting, centering, and squaring of the components prior to placement on a circuit board.

Abstract: Pressures applied to a component for pickup and placement thereof are each selectable, according to introduction of gas under pressure into a piston and cylinder configuration defined by a tool, such as a vacuum spindle, telescopically supported in a tool holder. An actuator with closed loop velocity and displacement control moves the tool holder to and fro along a longitudinal axis according to a known programmable controller. Thus, compression of the gas and relative displacement between the tool and holder allows controlled pick and place pressures to be varied and monitored programmably. The pressurized gas also acts to prevent dirt contamination of the bearing surface between the tool and holder and consequent impairment of telescoping and rotational movements therebetween.

Abstract: The present invention involves a method and apparatus for feeding axial lead components directly from a sequencer to an insertion head, while eliminating direct supplying of components to the insert head via a prededicated inventory such as reeled tapes or films having components attached thereto in a predetermined sequence. Preferably, an endless chain conveyor carries the components to the insert head in chain clips which positively retain the leads thereof while allowing centering of the bodies and electrical function testing of the components just prior to insertion of the leads into corresponding holes of a circuit board. Direct supply from a sequencer having a series of individually and programmably controlled dispenser heads provides for quick and flexible variation of an input sequence without manual intervention.
