Claims15
A method for making an ignition coil cassette, comprising:
- inserting a coil through an aperture in a main body portion of said ignition coil cassette;
- supporting a guide pin, said guide pin aligning said coil with respect to said main body portion, said guide pin being movably secured to a fixture support and being capable of movement in a range defined by a first position and a second position;
- ultrasonically welding said coil to said body portion;
- and
- supporting said main body portion of said ignition coil cassette and maintaining the position of said main body portion during the securement of said coil to said cassette.
A method for making an ignition coil cassette, comprising:
- inserting a coil through an aperture in a main body portion of said ignition coil cassette until an upper flange portion of said coil makes contact with a shoulder of said aperture;
- supporting a guide pin, said guide pin aligning said coil with respect to said main body portion, said guide pin being movably secured to a fixture support and being capable of movement in a range defined by a first position and a second position;
- ultrasonically welding said coil to said body portion;
- and
- supporting said main body portion of said ignition coil cassette and maintaining the position of said main body portion during the welding of said upper flange portion to said cassette.
