MANUFACTURE OF COIL COMPONENT AND COIL WIRE FORMING APPARATUS

摘要

PURPOSE:To automatically manufacture coil parts by moving a bobbin along the coil lead where a plurality of coils are developed in the predetermined product pitch and winding the coil lead to the side circumference of the bobbin. CONSTITUTION:Each part of side circumference of bobbin can be sequentially stacked to the corresponding part of coil lead by moving the bobbin along the coil lead under the developed condition, the coil lead is sequentially wound to the side circumference along the shape thereof under the stacked condition and the winding can be made without giving excessive tension to the coil lead. The slackening part of coil lead is pushed into the circumferencial groove of the bobbin for the shaping by making use of a holding chuck of the moving means. The respective terminals are inserted to a first and a second loops for tightening each loop and the end portions of coil leads are temporarily fixed. Moreover, the pitch between coils can be set to the predetermined product pitch through the switching.
