Abstract
Abstract Apparaus for automatically bonding pre-twisted wires to a number of pairs of ground and current contact points on a workpiece or substrate is disclosed. The apparatus forms a loop in the pre-twisted wires and bonds each wire to a ground or current contact point. The pre-twisted wire is then routed to the next pair of ground and current contact point for bonding.

Claim 1
Independent Claim
298 words
In combination with a positioning mechanism for positioning a workpiece, an automatic bonding and routing apparatus for bonding pre-twisted wires to a bond site on said workpiece and routing said pre-twisted wires for bonding on a subsequent bond site on said workpiece, thereby forming a net, said apparatus comprising: a turret-head; wire supply means mounted to said turret-head for supplying said pre-twisted wires; wire feeding means operable connected to said turret-head for feeding said pre-twisted wires from said wire supply means and forming a loop for bonding in said pre-twisted wires; bonding means operably connected to said turret-head and lying in a plane orthogonal thereto, having a center line parallel to a reference line passing through the center line of said formed loop for engaging said formed loop and bonding said pre-twisted wires to said bond site on said workpiece; and clamping means operably connected to said turret-head for receiving said pre-twisted wires from said wire feeding means and breaking said pre-twisted wires at a point beyond said bond site after bonding thereof, said clamping means comprising a housing support having guide rods affixed to said turret-head and sleeves slidably connected to said guide rods for positioning said clamping means towards or away from said bond site, a pair of receiving jaws operably connected to said housing means for receiving anad clamping said pre-twisted wires, first means operably connected to said receiving jaws for opening said receiving jaws so as to partially release, but yet, retain said pre-twisted wires, second means operably connected to said receiving jaws for opening thereof so as to completely release said pre-twisted wires, and third means attached to said slidable sleeves for controlling the position thereof on said guide rods so as to position said receiving jaws towards or away from said workpiece.

In combination with a positioning mechanism for positioning a workpiece, an automatic bonding and routing apparatus for bonding pre-twisted wires to a bond site on said workpiece and routing said pre-twisted wires for bonding on a subsequent bond site on said workpiece, thereby forming a net, said apparatus comprising: a turret-head; wire supply means mounted to said turret-head for supplying said pre-twisted wires; wire feeding means operable connected to said turret-head for feeding said pre-twisted wires from said wire supply means and forming a loop for bonding in said pre-twisted wires; bonding means operably connected to said turret-head and lying in a plane orthogonal thereto, having a center line parallel to a reference line passing through the center line of said formed loop for engaging said formed loop and bonding said pre-twisted wires to said bond site on said workpiece; and clamping means operably connected to said turret-head for receiving said pre-twisted wires from said wire feeding means and breaking said pre-twisted wires at a point beyond said bond site after bonding thereof, said clamping means comprising a housing support having guide rods affixed to said turret-head and sleeves slidably connected to said guide rods for positioning said clamping means towards or away from said bond site, a pair of receiving jaws operably connected to said housing means for receiving anad clamping said pre-twisted wires, first means operably connected to said receiving jaws for opening said receiving jaws so as to partially release, but yet, retain said pre-twisted wires, second means operably connected to said receiving jaws for opening thereof so as to completely release said pre-twisted wires, and third means attached to said slidable sleeves for controlling the position thereof on said guide rods so as to position said receiving jaws towards or away from said workpiece.
Claim 3
Dependent Claim
238 words
Apparatus for bonding pre-twisted wires comprising: housing support means affixed to a turret-head; probe means having spaced probe tips operably connected to said housing support means for picking-up a formed loop of said pre-twisted wires for bonding and positioning each wire of said formed loop a predetermined distance onto its respective signal or ground pad on a workpiece; first moving means attached to said housing support means for moving said probe means towards or away from said workpiece; first biasing means attached to said housing support means for biasing said probe means away from said workpiece; bond tips attached to said housing support means positioned between said spaced probe tips for bonding said formed loop of said pre-twisted wires to said signal pad and said ground pad on said workpiece; second moving means attached to said housing support means for positioning said bond tips toward or away from said workpiece; second biasing means affixed to said housing support means and said bond tips for biasing said bond tips away from said workpiece; and means for applying a thermal pulse to said probe means, said thermal pulse having a controlled thermal cycle so that insulation is melted from said formed loop of said pre-twisted wires and so that solder on said signal pad and said ground pad on said workpiece is melted thereby bonding said formed loop of said pre-twisted wires to said signal pad and said ground pad.

Claim 5
Dependent Claim
122 words
Apparatus for feeding pre-twisted wires comprising: a wire feed unit; a wire feed housing support means having guide posts with slidable sleeves thereon for supporting and positioning said wire feed unit; biasing means affixed to said wire feed housing support means for biasing said wire feed unit away from a workpiece; moving means for positioning said slidable sleeves and said wire feed unit on said guide posts; first means for rotating said wire feed unit thereby reversing the relative position of said pre-twisted wires when said pre-twisted wires are not aligned with an appropriate bond site; and second means for rotating said pre-twisted wires in a direction opposite to the pitch of said pre-twisted wires so as to form a loop therein.
