Abstract:
A method of manufacturing a coil using a winding machine and attaching the coil to contact points of an electric circuit using a circuit fixture, comprising:bringing a first end of a winding filament in a stretched state to a predetermined first position located inwardly of the coil;temporarily anchoring the first end of the winding filament in a vacuum hole in the winding machine through suction;winding said coil with the winding filament to create a finished coil while keeping the first end at said first position;bringing the winding filament in a stretched state to a predetermined second position located inwardly of the coil and separate from said first position;cutting the winding filament to create a second end;temporarily anchoring said second end in the vacuum hole in the winding machine through suction;contacting the circuit fixture with the winding machine, with the electric circuit on the circuit fixture positioned at a predetermined third position corresponding to the first and second positions in the winding machine to collect the finished coil;drawing the first end and the second end of the winding filament by suction into a vacuum hole in the circuit fixture such that, as the circuit fixture collects the finished coil, the first and second ends of the winding filament remain in the stretched state in positions corresponding to the first position and the second position, respectively, and portions of said first and second ends are in contact with the contact points on the electric circuit located at the third position;welding the portions of said first and second ends that are in contact with said contact points to said contact points.
