Abstract
Abstract Apparatus for providing electrical circuit components with terminal pins firmly secured to the component substrate. Both method and apparatus are provided serving to automatically position a terminal pin with respect to the substrate, and to form a head on the pin on one surface of the substrate, and a bulge on the pin adjacent the opposite surface of the substrate from the head to secure the pin with respect to the substrate without damaging the substrate.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
225 words
Means for applying conducting pins to a substrate formed with a plurality of spaced apertures for receipt of the pins, said means comprising: pin supporting means, said pin supporting means comprising a nest assembly for use in inserting pins into a substrate, said nest assembly comprising: a nest housing having an upper surface; a pin receiving nest reciprocably mounted in said housing and having a plurality of pin receiving openings extending through said nest; a punch assembly reciprocably mounted beneath said nest in said housing, said punch assembly having a plurality of pin punches extending into the pin receiving nest openings, and reciprocable therein; substrate gripping means engaging and gripping the substrate at a fixed position with respect to said pin supporting means, said substrate gripping means comprising substrate grippers mounted to move over the upper surface of said nest housing to engage a substrate in position over said pin receiving nest; pin moving means engaging said pin to move an entry end of a supported pin into an aperture of said substrate; heading means engaging the end of the pin inserted through the substrate to apply pressure thereto to upset the pin to form a head thereon; and bulging means exerting a pressure on said pin to upset the pin on the side of the substrate opposite to the headed end of said pin.
Claim 2
Dependent Claim
225 words
Means for applying conducting pins to a substrate formed with a plurality of spaced apertures for receipt of the pins, said means comprising: pin supporting means, said pin supporting means comprising a nest assembly for use in inserting pins into a substrate, said nest assembly comprising: a nest housing having an upper surface; a pin receiving nest reciprocably mounted in said housing and having a plurality of pin receiving openings extending through said nest; a punch assembly reciprocably mounted beneath said nest in said housing, said punch assembly having a plurality of pin punches extending into the pin receiving nest openings, and reciprocable therein; substrate gripping means engaging and gripping the substrate at a fixed position with respect to said pin supporting means, said substrate gripping means comprising substrate grippers mounted to move over the upper surface of said nest housing to engage a substrate in position over said pin receiving nest; pin moving means engaging said pin to move an entry end of a supported pin into an aperture of said substrate; heading means engaging the end of the pin inserted through the substrate to apply pressure thereto to upset the pin to form a head thereon; and bulging means exerting a pressure on said pin to upset the pin on the side of the substrate opposite to the headed end of said pin.
Claim 3
Dependent Claim
30 words
Means as in claim 1 in which said pin supporting means maintains a plurality of pins in a spaced array corresponding to the spacing of the apertures in the substrate.
Claim 4
Dependent Claim
32 words
Means as in claim 1 in which said pin supporting means are positioned to engage said substrate after said pin moving means move the entry end of the pin into the substrate.
Claim 5
Dependent Claim
36 words
Means as in claim 3 in which said pin, moving means move said pin toward said substrate from said pin supporting means with the entry end of said pin laterally unrestrained as it approaches said substrate.
Claim 6
Dependent Claim
35 words
Means as in claim 3 in which said pin supporting means are moved to a position spaced from the substrate after said pins are headed and prior to presenting said pins to said bulging means.
Claim 7
Dependent Claim
20 words
Means as in claim 1 in which said pin receiving nest is formed with a punch guide beneath said nest.
Claim 8
Dependent Claim
43 words
Means as in claim 6 in which said pin punches are of a stepped configuration with a portion of said punches engaging said pins relatively thinner than a portion of the pin punches remote from the pins and moving in said punch guide.
Claim 9
Dependent Claim
21 words
Means as in claim 1 in which said housing is formed with a bore in which said nest may be moved.
Claim 10
Dependent Claim
34 words
Means as in claim 6 in which said pin receiving nest is supported on a punch plunger guide having a bearing surface; and a punch plunger reciprocably mounted to move over said bearing surface.
Claim 11
Dependent Claim
37 words
Means as in claim 1 in which spring means bias said pin receiving nest away from the upper surface of said housing; and spring means bias said punch assembly away from the upper surface of said housing.
Claim 12
Dependent Claim
31 words
Means as in claim 1 mounted in a dial for stepped movement between a pin receiving station, a substrate positioning station, a pinning station, a heading station, and a bulging station.
Claim 13
Dependent Claim
31 words
Means as in claim 11 in which said dial moves said nest assembly past an inspection station after said substrate positioning station; and to an ejection station after said bulging station.
Claim 14
Dependent Claim
50 words
Means as in claim 11 in which a cam assembly is arranged beneath said dial having a cam surface engaging a cam follower on said pin receiving nest, and a cam surface engaging a cam follower on said punch assembly to effect relative movement between said nest and punch assembly.
Claim 15
Dependent Claim
38 words
Means as in claim 13 in which said cam assembly comprises: a cam plunger engaging the cam follower; a plunger stem; and a wedge member engaging said plunger permitting relative adjustment between said plunger and said cam follower.
Claim 16
Dependent Claim
43 words
Means as in claim 14 in which said cam assembly comprises: a spring biasing said plunger downwardly; said plunger being baised downwardly against said wedge member by said spring; and means for moving said wedge member to adjust the position of said plunger.
