Abstract
Abstract An electronic component lead cutting and clinching mechanism having a linkage arrangement whereby the component leads are severed and a channel carries them out of the cutting and clinching area. The mechanism has a linkage attached to a cutting rod, the linkage being attached, in turn, to two pneumatic cylinders, which respectively power an anvil in which the cutting rod is located to bring it up to position beneath a circuit board and operate the cutting rod.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
118 words
An apparatus for cutting and clinching leads of electronic components projecting beneath circuit boards, said apparatus comprising at least one housing, means supporting said housing for longitudinal movement, means for moving said housing longitudinally, an anvil assembly mounted for vertical movement on said housing, lead cutting and clinching means on said anvil assembly, a first piston means to impart a sinusoidal motion stroke to said cutting and clinching means, a second piston means for moving said anvil assembly vertically to place said cutting means in position to cut and clinch leads, said second piston means being associated with said first piston means and means adapted to carry said severed lead portions away from said cutting and clinching means.
Claim 2
Independent Claim
118 words
An apparatus for cutting and clinching leads of electronic components projecting beneath circuit boards, said apparatus comprising at least one housing, means supporting said housing for longitudinal movement, means for moving said housing longitudinally, an anvil assembly mounted for vertical movement on said housing, lead cutting and clinching means on said anvil assembly, a first piston means to impart a sinusoidal motion stroke to said cutting and clinching means, a second piston means for moving said anvil assembly vertically to place said cutting means in position to cut and clinch leads, said second piston means being associated with said first piston means and means adapted to carry said severed lead portions away from said cutting and clinching means.
Claim 3
Dependent Claim
26 words
An apparatus as in claim 1 including a linkage means connecting said first piston means to said cutting and clinching means and to said anvil assembly.
Claim 4
Dependent Claim
32 words
An apparatus as in claim 2 wherein said cutting and clinching means comprises a rod having a beveled cutting and clinching end, said rod received within a bore in said anvil assembly.
Claim 5
Dependent Claim
89 words
An apparatus as in claim 3 wherein said linkage means comprises a pivotable member pivotally mounted on said anvil assembly, means pivotally connEcting said rod to said pivotable member, an adjustment member pivotally connected to said pivot member and said first piston means, said adjustment member having means by which its length may be varied, a link member pivotally connected to said pivotable connection between said adjustment member and said first piston means at one end and to the lower end of said anvil assembly at its other end.
Claim 6
Dependent Claim
81 words
An apparatus as in claim 4 wherein said first piston means imparts a horizontal stroke and said second piston means imparts a vertical stroke whereby when said second piston means raises said anvil assembly to a cut and clinch position beneath a circuit board, it cocks the linkage assembly so that when said first piston means is actuated, it imparts a sinusoidal motion to said rod and tends to lock the linkage assembly in place at the end of the stroke.
Claim 7
Dependent Claim
48 words
An apparatus as in claim 5 wherein said means adapted to carry away severed lead portions comprises a slot in said anvil assembly, said slot being in open communication with said cutting rod bore, the lead portions adapted to extend down into said slot prior to being severed.
Claim 8
Dependent Claim
67 words
An apparatus as in claim 1 wherein said lead cutting and clinching means includes a rod, said cutting rod being received within a bore in said anvil assembly, said means adapted to carry away severed lead portions comprising a slot in said anvil assembly, said slot being in open communication with said cutting rod bore, the component lead portions extending into said slot prior to being severed.
Claim 9
Dependent Claim
17 words
An apparatus as in claim 7 including a suction means connected to the bottom of said slot.
Claim 10
Dependent Claim
55 words
An apparatus as in claim 1 wherein said first and second piston means comprise cylinders with pneumatically operated pistons, said first cylinder being single action and having one port and a means to sense air pressure when said first piston nas completed its stroke, and said second cylinder being double action and having two ports.
Claim 11
Dependent Claim
25 words
An apparatus as in claim 1 and including guide means on said housing adapted to guide the upward and downward movement of said anvil assembly.
Claim 12
Dependent Claim
81 words
An apparatus as in claim 2 wherein said anvil assembly has a horizontal planar top portion, a bore in said portion, a tubular insert in bore and having a beveled end portion, said cutting and clinching means including a rod mounted in said bore for sliding movement, said rod having a beveled cutting end portion, the beveled surfaces of said insert and rod being coplanar with said top portion surface when said rod is at the clinching end of its stroke.
