Abstract
Abstract A quantity of circuit chips are slidingly received in end to end relation in an elongated receptacle or "stick". The required number of such sticks are located in parallel groups at each side of a substrate mounted on an adjustable support. A pair of vacuum heads reciprocate along a path transversely of the substrate a fixed amount from a first extreme with the vacuum head located immediately over the endmost chip in a stick, to a second extreme which is a constant distance from the first position and lying over the substrate. The substrate is positioned to the proper x-y location such that when the transfer mechanism moves a chip to the position over the substrate, it will be properly located at the correct part of the substrate circuit. The sticks are indexable as needed to a position presenting the endmost chip of the selected stick underneath the outer extreme of the movement of the vacuum head. Control apparatus positions the substrate in any desired series of x-y locations.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
199 words
Apparatus for locating components of different kinds on a substrate surface, comprising: first and second magazines arranged in mutually spaced relation; a plurality of elongated trays arranged in two sets on said first and second magazines in side-by-side relation, each tray including a plurality of components in end-to-end arrangement along the tray length; a table carrying the substrate situated between said first and second magazines; a pair of vacuum retainers mounted in fixed spaced relation on a plate; means for moving said plate and vacuum retainers along a first path from a first extreme with one of said vacuum retainers disposed spaced above the first magazine and the other retainer spaced above the substrate to a second extreme with the other retainer spaced above the second magazine and the first recited retainer spaced above the substrate, and along a second path toward and then away from the substrate and magazines each time the plate and vacuum retainers are located at the first and second extremes of the first path; and means for establishing a vacuum in the retainers to secure components thereto and for breaking the vacuum in each retainer at the conclusion of its movement toward the substrate.

Apparatus for locating components of different kinds on a substrate surface, comprising: first and second magazines arranged in mutually spaced relation; a plurality of elongated trays arranged in two sets on said first and second magazines in side-by-side relation, each tray including a plurality of components in end-to-end arrangement along the tray length; a table carrying the substrate situated between said first and second magazines; a pair of vacuum retainers mounted in fixed spaced relation on a plate; means for moving said plate and vacuum retainers along a first path from a first extreme with one of said vacuum retainers disposed spaced above the first magazine and the other retainer spaced above the substrate to a second extreme with the other retainer spaced above the second magazine and the first recited retainer spaced above the substrate, and along a second path toward and then away from the substrate and magazines each time the plate and vacuum retainers are located at the first and second extremes of the first path; and means for establishing a vacuum in the retainers to secure components thereto and for breaking the vacuum in each retainer at the conclusion of its movement toward the substrate.
Claim 3
Dependent Claim
53 words
Apparatus as in claim 1, in which each tray includes an elongated member having a longitudinally extending slot in an outer surface thereof for receiving a plurality of similarly dimensioned components in end-to-end relation, and a cover received over the components preventing all but the endmost component from being withdrawn from the tray.
Claim 4
Dependent Claim
33 words
Apparatus as in claim 1, in which each tray is supported on the magazine with an endmost component being lower than the others, whereby gravity urges the components toward said tray endmost position.
Claim 5
Dependent Claim
27 words
Apparatus as in claim 3, in which there is further provided means carried by said magazines for vibrating said trays to aid gravity urging of the components.
Claim 6
Dependent Claim
35 words
Apparatus as in claim 1, in which there is further provided means for moving the magazines transversely of the tray long dimension cyclically advancing each of the trays into operative relation with the vacuum retainers.
Claim 7
Dependent Claim
33 words
Apparatus as in claim 1, in which there is provided means for adjustably locating said substrate to any desired predetermined x and y position with respect to said retainers first and second extremes.
Claim 8
Dependent Claim
34 words
Apparatus as in claim 6, in which each of said trays includes different components and there are further provided means selectively adjustable for sequentially locating the components of the different trays at predetermined locations.
Claim 9
Dependent Claim
50 words
Apparatus as in claim 1, in which each vacuum retainer includes at least one hollow tube interconnected with a low air pressure source, a differential pressure electric switch operatively connected with said hollow tube, and indicating means actuated by said switch on a differential air pressure existing in said tube.
Claim 10
Dependent Claim
177 words
In a process of locating components on a substrate where a vacuum retainer is cyclically moved toward a component, securing contact between the retainer and the components is established, and the so-secured component is moved to the substrate and the retainer disengages the component, leaving it resting on the substrate, comprising the steps of: arranging the components in an end-to-end line in a holder having open ends facing the ends of the line of components, said components being freely slidable in a direction along the components line toward either of the holder open ends and restrained from movement in all other directions; continuously forcing the line of components toward one of the holder open ends such that an endmost component tends to move toward the holder open end; moving the holder to align the endmost component with the retainer; securingly engaging said endmost components with the retainer; and removing said endmost component from the retainer securingly engaged with said endmost component whereby the next adjacent component in the line of components is forced into the endmost position.
