Abstract
Abstract Electrical components having generally parallel leads extending in one direction from one side of their bodies, respectively, are successively transferred to a conveyor means movable through sequential processing stations to prepare the leads for circuit board connection or sequencing preparatory to such connection. Spaced lead grippers on the conveyor means control lead portions adjacent to the bodies of the components. The stations sucessively act to determine the standoff length of the leads from the bodies of the components, reform remaining portions of the leads in coaxial relation while maintaining the standoff length, check for omission of a reformed component from proper position in the series and, upon release from the grippers, tape the coaxial portions of the leads of adjacent components in parallel, side-by-side relation. Preferably, the means for checking reformed component presence also controls turning of a reel for storing the repackaged components.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
129 words
A machine for processing components having generally parallel leads extending from one side of their bodies, respectively, comprising: conveyor means movable from a loading station, through successive processing stations, to an unloading zone; uniformly spaced lead grippers mounted on said conveyor means for controlling portions of the leads adjacent to their respective bodies; means on at least one subsequent station for cooperating with said grippers to bend the distal ends of said leads carried thereby into coaxial relation with one another and substantially at right angles with respect to their proximal ends which comprise said components' standoff lengths; a lead taping mechanism, and means for transferring the successive formed components from the conveyor grippers with their coaxial lead portions in position to be taped by the lead taping mechanism.
Claim 2
Dependent Claim
129 words
A machine for processing components having generally parallel leads extending from one side of their bodies, respectively, comprising: conveyor means movable from a loading station, through successive processing stations, to an unloading zone; uniformly spaced lead grippers mounted on said conveyor means for controlling portions of the leads adjacent to their respective bodies; means on at least one subsequent station for cooperating with said grippers to bend the distal ends of said leads carried thereby into coaxial relation with one another and substantially at right angles with respect to their proximal ends which comprise said components' standoff lengths; a lead taping mechanism, and means for transferring the successive formed components from the conveyor grippers with their coaxial lead portions in position to be taped by the lead taping mechanism.
Claim 3
Dependent Claim
42 words
A machine as recited in claim 1 wherein said conveyor means is in the form of a rotary wheel, and operating movement of the grippers is controlled by a biased latch that is pivoted into and out of association with said grippers.
Claim 4
Dependent Claim
43 words
A machine as recited in claim 1 wherein said grippers comprise a pair of jaw members that are biased in the closed condition until they are opened by a pressurizably controlled plunger means whereupon said biased latch swings to hold said jaws apart.
Claim 5
Dependent Claim
47 words
A machine as recited in claim 1 wherein a pressurizably controlled plunger means is used to close said grippers by pivoting an arm about a point, wherein said arm releases said biased latch from its association with said grippers, the jaws of said grippers thereupon snapping shut.
Claim 6
Dependent Claim
76 words
A machine as recited in claim 1 wherein a mechanism is provided for reeling up the components when taped by said taping means which includes: a declutchable motorized indexer that is operatively connected to drive said taping means, and a sensor for checking on the presence and position of each component to be presented by said grippers to said taping means controls a circuit for declutching said motorized indexer when a component is missing or mispositioned.
Claim 7
Dependent Claim
135 words
A machine as recited in claim 1, wherein said means for cooperating with said grippers to bend said leads includes: a power driven plunger arrangement; a multisided cam member reciprocally movable toward and away from said components carried on said rotary wheel; a first pair of cam followers attached respectively to a pair of arms, said arms having extremities which move into place between said leads, said extremities being movable apart from one another to bend said leads which extend out of the jaws of said grippers; a second cam follower movable by said multisided cam member, said second cam follower causing said arms to move into place between said leads, and to return said extremities of said arm out of the plane of said leads upon withdrawal of said reciprocally movable multisided cam member.
Claim 8
Dependent Claim
78 words
A machine as recited in claim 1 wherein said means for cooperating with said grippers to bend said leads also includes: a generally T-shaped reciprocally movable plunger having grooved arms; a pneumatically operable means for reciprocally moving said movable T-shaped plunger; said leads mating into said grooves in said arms to insure a generally 90° bend therein; said sensor for checking the presence and position of each component presented by said grippers being disposed at said subsequent station.
Claim 9
Dependent Claim
29 words
A machine as recited in claim 7 wherein said motorized indexer is declutched from driving said lead taping mechanism to permit a continuity of components to be applied thereon.
Claim 10
Dependent Claim
151 words
A machine as recited in claim 8 wherein said taping means also includes: a pair of pickup wheels each having an array of crenels spaced upon their peripheries; each of said wheels also having a circumferentially directed channel therearound; a pair of tape supply reels which supply tape, sticky side up, into longitudinal association with said circumferentially directed channels; said grippers releasing said components to placement means which inserts each pair of coaxial leads across said crenels in each pickup wheel, each lead adhering to said tape in its respective channel; a second pair of tape supply reels that supply tape sticky side down into said channel, said taping being pressed against said leads and said sticky side up tape by a pair of rollers that rollingly mate with said channels immediately after said crenels each have a component lead inserted thereacross, said pickup wheels intermittently rotated to receive new components.
Claim 11
Dependent Claim
172 words
A machine as recited in claim 9, wherein said placement means comprises: at least one set of movable bifurcated fingers comprised of an upper pair of fingers and a lower pair of fingers; a second pressurizable piston cylinder which has a piston rod whose movement permits a pivotal response in said lower set of bifurcated fingers; a first pressurizable piston cylinder which has a piston rod attached to a frame which supports both pairs of bifurcated fingers, the movement of said piston rod permitting longitudinal travel of said bifurcated fingers; a third pressurizable piston cylinder disposed on said frame and having a piston rod attached to said bifurcated fingers so as to permit vertical movement therewith; said first, second and third pressurizable piston cylinders being actuatable upon a signal which causes said bifurcated fingers to move toward and grasp said leads of said components from the jaws of said grippers as they are opening, and place said leads across said crenels as each unfilled crenel is presented on said rotating pickup wheel.
