Abstract

This wire stripper uses a high voltage to remove insulation. High voltage transformer 1 has one lead connected to a wire supply spool 2 and the other lead to ground. Insulation coated wire 3 is connected to spool 2 and thus also to transformer 1.

Wire Stripper

This wire stripper uses a high voltage to remove insulation. High voltage transformer 1 has one lead connected to a wire supply spool 2 and the other lead to ground. Insulation coated wire 3 is connected to spool 2 and thus also to transformer 1.

Just prior to a bonding operation, the end of wire 3 is placed in close proximity to ground electrode 4. The separation between wire 3 and electrode 4 is selected to allow the output voltage of transformer 1 to bridge the gap.

The primary winding of transformer 1 is momentarily connected to a power source. The resulting arc between wire 3 and electrode 4 strips the insulation from the wire. The bare wire can be bonded to circuit board 5 by ultrasonic bonding head 6.
