Abstract
Abstract Electronic components, such as DIP's, which have at least one row of generally right angular or generally linear leads projecting from their bodies, are dispensed from their respective columns in a magazine of the machine, one by one, and as predeterminedly selected by a picker controlled by computer means. Due to occasional obstructive slight irregularities in the formation of the bodies and/or their leads, means is provided to insure exact registration of each selected component with a component inserting mechanism. Improved means for rapid, reliable release and transfer of the successive selected components from the magazine, and between the delivery ends of its respective columns and, a lead conditioning means at the locality of such registration, enable efficient coordination with the inserting mechanism whereby continuous output at a higher rate is attainable.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
156 words
In combination with a component inserting machine having means for inserting components provided with in-line leads, a plurality of raceways for supplying the components to be inserted, a cross-slide means for locating a circuit board relative to the inserting means, and a computer controlled means for automatically operating the inserting means and the cross-slide means according to predetermined program, a movable picker assembly responsive to the computer controlled means for selecting successive predetermined components from the respective raceways according to said program and delivering them individually to the inserting means, said picker assembly comprising component escapement means including a detent arranged to cooperate with the raceways, respectively, mechanism for operating the detent of said escapement means comprising a plurality of actuating arms, and a power means responsive to the computer controlled means when the picker is in predetermined position for causing one of said arms to release each selected component in succession to the picker assembly.
Claim 2
Dependent Claim
156 words
In combination with a component inserting machine having means for inserting components provided with in-line leads, a plurality of raceways for supplying the components to be inserted, a cross-slide means for locating a circuit board relative to the inserting means, and a computer controlled means for automatically operating the inserting means and the cross-slide means according to predetermined program, a movable picker assembly responsive to the computer controlled means for selecting successive predetermined components from the respective raceways according to said program and delivering them individually to the inserting means, said picker assembly comprising component escapement means including a detent arranged to cooperate with the raceways, respectively, mechanism for operating the detent of said escapement means comprising a plurality of actuating arms, and a power means responsive to the computer controlled means when the picker is in predetermined position for causing one of said arms to release each selected component in succession to the picker assembly.
Claim 3
Dependent Claim
33 words
The combination of claim 1 wherein the actuating arms are mounted on a common shaft for limited rotation therewith and effective actuation of the escapement means by a predetermined one of said arms.
Claim 4
Dependent Claim
64 words
The combination of claim 2 wherein the picker assembly comprises a block slidably mounting a pair of spring-pressed plungers both of which are arranged for potential operative engagement with each of said arms, one of the plungers being disposed to control said detent, and the other of the plungers being disposed to be displaced by the arms, respectively, to a component-releasing, yieldingly held-open position.
Claim 5
Dependent Claim
76 words
The combination of claim 1 wherein the picker assembly is driven by a belt directly connected thereto for movement along a path adjacent to the delivery ends of the respective raceways and said component inserting means, said assembly includes a pocket for accommodating each selected component, and a locking means in said assembly is arranged to be operable by said one of the actuating arms to relesably secure and position the selected component in said pocket.
Claim 6
Dependent Claim
70 words
The combination of claim 1 wherein one of the detents in the spring-pressed plunger movable transversely into the respective cooperating raceways, that detent serving as a yieldable probe for detecting the presence of a component just above the delivery end of each of the raceways, and a circuit including a switch operable by the plunger when it fails to engage a component in the raceway to render the machine inoperative.
Claim 7
Dependent Claim
71 words
The combination of claim 1 wherein the picker assembly comprises an actuating means operable by movement of the detent in one direction to clamp a component in a raceway above its delivery end, and a spring plunger for yieldably retaining an endmost component in the raceway, said actuating means being arranged, in response to movement of the detent in said one direction, to cause said plunger to release the endmost component.
Claim 8
Dependent Claim
103 words
The combination of claim 1 wherein, intermediate a component delivery position of said picker assembly and the inserting means, there is a lead conditioning means, said lead conditioning means comprising a pair of inside formers respectively adapted to be received between the opposite sides of each component body to be delivered and an adjacent row of its generally in-line leads, and a pair of outside formers movable inwardly against the outer surfaces of the leads and toward the inside formers, the lead-engaging faces of the inside and outside formers being substantially parallel in lead pressing relation whereby jamming of the component is avoided.
Claim 9
Dependent Claim
19 words
The combination of claim 7 wherein operation of the lead conditioning means is responsive to said computer controlled means.
Claim 10
Dependent Claim
147 words
In a machine for inserting in-line lead components, means for inserting successive components with their leads uniformly extending in divergent rows from opposite sides of their respective component bodies, and lead conditioning mechanism for straightening the leads of each row of a component prior to its delivery to said means, said mechanism comprising a fixed member engageable with the component body, spaced, tapering forming means having faces respectively yieldingly engageable with the inside surfaces of the leads of each row, a spring-pressed member mounted on said forming means for engaging the body to position it against said fixed member prior to lead engagement by said tapering forming means, outside forming means having lead engaging faces respectively substantially parallel to those of said forming means, and mechanism for moving the outside forming means inwardly to press the rows of leads against said faces of the tapering forming means.
Claim 11
Dependent Claim
147 words
In a machine for inserting in-line lead components, means for inserting successive components with their leads uniformly extending in divergent rows from opposite sides of their respective component bodies, and lead conditioning mechanism for straightening the leads of each row of a component prior to its delivery to said means, said mechanism comprising a fixed member engageable with the component body, spaced, tapering forming means having faces respectively yieldingly engageable with the inside surfaces of the leads of each row, a spring-pressed member mounted on said forming means for engaging the body to position it against said fixed member prior to lead engagement by said tapering forming means, outside forming means having lead engaging faces respectively substantially parallel to those of said forming means, and mechanism for moving the outside forming means inwardly to press the rows of leads against said faces of the tapering forming means.
Claim 12
Dependent Claim
18 words
A machine as in claim 9 wherein the outside forming means is actuatable inwardly by a toggle arrangement.
Claim 13
Dependent Claim
49 words
A machine as in claim 9 wherein a single power actuatable mechanism is provided for operating in sequence the body positioning member, the tapering inside lead forming means, and then the outside forming means, said power actuatable mechanism being reversible to release the component after its leads are straightened.
