JPS6460193A - Manufacture of voice coil for speaker - Google Patents

Abstract

PURPOSE:To make the stabilization of quality and the consistent rationalization of a process and to manufacture at low cost by soldering-connecting a voice coil winding leader line and a tinsel wire, after that, applying ultraviolet-ray hardening type adhesive agent to the soldering-connected part, irradiating ultraviolet rays, and after that, executing the severing of the tinsel wire. CONSTITUTION:A tinsel Wire is supplied to the prescribed position of a coil 8a of a coil bobbin 8, a leader line of a fixed width is wound on it, an excessive wire is severed and after that, a small quantity of flux 16 is applied. Next, a soldering 14 is executed, an ultraviolet-ray hardening resin is used as a reinforcing adhesive 15b and applied to the part of the soldering 14 of the tinsel wire 9, after that, the ultraviolet rays are irradiated, the reinforcing adhesive 15b is fixed and the severing of the tinsel line 9 is executed. Thus, the process can be made on-line by the using of the ultraviolet-ray hardening adhesive agent and manufacturing efficiency is good. Since it hardens in an instant when an ultraviolet-ray lamp is lit to it, in the severing, a shock at the time of a cutting can be endured, since a disconnection and a drying are unnecessary, fatal defects such as a bobbin deformation can be retrenched and further, by the rationalization of the processing process, a cost merit can be obtained.
