Abstract
Abstract The mechanism cuts component lead portions projecting from a support such as a circuit board though the leads may be spaced apart at different distances, and then clinches them against the board. Additionally, the mechanism is movable heightwise relative to the support for clearance purposes and adapted to be shifted both in X-Y directions and with selected radial orientation between preset angles. The clinching is done in opposite directions and normal to a line interconnecting the points from which the leads protrude thereby stabilizing the position of a component body.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
172 words
Cut-clinch mechanism for operating on the variably spaced leads of components mounted on a circuit board or the like, said mechanism comprising means for pivotally supporting a pair of levers for rotation in opposite directions about an axis substantially parallel to the board, the means including a through-opening and an axially extending through-slot aligned therewith, one of the levers having a lead-receiving hole movable into and out of angular alignment with said through-opening and the other of said levers having an axially extending slot movable into and out of angular alignment with said through-slot, mechanism for moving the support means relative to the board to cause end portions of the leads of a component projecting therefrom to extend into the aligned hole and through-opening on the one hand and the aligned slots on the other hand, and other mechanism for counter-rotating the levers about said axis to cut the leads in cooperation with said support means and then bend and wipe the shorn lead portions in opposite directions against the circuit board.
Claim 2
Dependent Claim
172 words
Cut-clinch mechanism for operating on the variably spaced leads of components mounted on a circuit board or the like, said mechanism comprising means for pivotally supporting a pair of levers for rotation in opposite directions about an axis substantially parallel to the board, the means including a through-opening and an axially extending through-slot aligned therewith, one of the levers having a lead-receiving hole movable into and out of angular alignment with said through-opening and the other of said levers having an axially extending slot movable into and out of angular alignment with said through-slot, mechanism for moving the support means relative to the board to cause end portions of the leads of a component projecting therefrom to extend into the aligned hole and through-opening on the one hand and the aligned slots on the other hand, and other mechanism for counter-rotating the levers about said axis to cut the leads in cooperation with said support means and then bend and wipe the shorn lead portions in opposite directions against the circuit board.
Claim 3
Dependent Claim
27 words
Mechanism as in claim 1 wherein said support means is a shaft held against rotation relative to said levers and providing circular bearing surfaces for the levers.
Claim 4
Dependent Claim
34 words
Mechanism as in claim 2 wherein the shaft is longer than a line interconnecting lead-receiving holes of the component in said board and the levers rotate about a common axis parallel to said line.
Claim 5
Dependent Claim
47 words
Mechanism as in claims 1, 2 or 3 wherein the hole in one of the levers and the through-slot in the other respectively have a radially inner lead-cutting edge and a radially outer mouth edge adapted to bend and wipe a shorn lead portion against the board.
Claim 6
Dependent Claim
29 words
Mechanism as in claim 1 wherein said mechanism for moving the support means and said other mechanism are operable successively and independently of one another by fluid pressure means.
Claim 7
Dependent Claim
44 words
Mechanism as in claim 5 wherein a further fluid pressure-operated means is operatively connected to rotate said support means and said levers jointly about an axis substantially normal to the board to accommodate different lead orientation of components to be successively cut and clinched.
Claim 8
Dependent Claim
17 words
Mechanism as in claim 6 wherein said axis is aligned with the through-opening in said supporting means.
Claim 9
Dependent Claim
130 words
In a mechanism for cutting the clinching variably spaced leads of components mounted on circuit boards or the like, a cut-clinch unit movable toward and from the board, said unit comprising a shear bar and a pair of cut-clinch members mounted on the bar for movement in opposite directions relative to the bar and away from an initial operating position to shear and then wipe the leads against the board, said shear bar having a first lead-receiving hole or slot and an elongated axially aligned slot for respectively receiving endwise the variably spaced lead portions to be cut, and power means for moving the unit relative to the board and actuating the cut-clinch members when the lead portions of a component have been received in the hole and elongated slot.
Claim 10
Dependent Claim
130 words
In a mechanism for cutting the clinching variably spaced leads of components mounted on circuit boards or the like, a cut-clinch unit movable toward and from the board, said unit comprising a shear bar and a pair of cut-clinch members mounted on the bar for movement in opposite directions relative to the bar and away from an initial operating position to shear and then wipe the leads against the board, said shear bar having a first lead-receiving hole or slot and an elongated axially aligned slot for respectively receiving endwise the variably spaced lead portions to be cut, and power means for moving the unit relative to the board and actuating the cut-clinch members when the lead portions of a component have been received in the hole and elongated slot.
Claim 11
Dependent Claim
37 words
A mechanism as in claim 8 wherein the power means comprises a first piston-cylinder device for controlling relative movement of approach between the board and the unit, and a second piston-cylinder device for actuating the cut-clinch members.
Claim 12
Dependent Claim
68 words
A mechanism as in claim 8 or 9 wherein one of the members of said unit has a radial lead-receiving through-hole or slot which in an initial position is in angular registration with the bar hole or slot, and the other of said members is formed with an axially elongated through-slot which in an initial position is in angular registration with the elongated slot in said cutter bar.
Claim 13
Dependent Claim
36 words
A mechanism as in claim 8 and a third piston-cylinder device operatively connected to the cut-clinch unit to rotate it predeterminedly about an axis perpendicular to the board when the board and unit are relatively retracted.
