Abstract

A programmable winding mechanism is able to wind a coil around a thin, standard, metallized ceramic substrate in a manner to be able not to wind wire into the areas of the substrate where pins are located. This requires an automatic skipping of those areas where the pins are located on the surface of the substrate.

Programmable Coil Winding Mechanism

A programmable winding mechanism is able to wind a coil around a thin, standard, metallized ceramic substrate in a manner to be able not to wind wire into the areas of the substrate where pins are located. This requires an automatic skipping of those areas where the pins are located on the surface of the substrate.

This function is accomplished by using a transverse mechanism which has the ability to be programmed to skip over the areas where wires are not required. As shown in the figure, the pin substrate 1, on which the coil is to be wound, is held rigidly by a fixture 2.

The fixture 2 is turned radially by a motor 3, and the wire 4 to be wound around the substrate is held in the correct relationship by the wire guide mechanism 5. The guide mechanism is mounted on and a part of a rack 6, which is driven laterally by a gear 7 and a stepper motor 8. Alternatively, the mechanism could be driven laterally by a screw or other drive mechanism.

To actuate the start/stop sequence for the transverse mechanism, a control program, such as a tape, would drive the motors 3 and 8. The motor 3 could turn at a constant RPM while the stepper motor 8 could provide an intermittent motion to the wire guide 5 at the correct time to permit the wire 4 to be wound correctly and in between the pins 9 on the substrate 1. Any suitable program drive mechanism, in addition to a tape drive, could be used to appropriately control the winding sequence.
