[0003]

In the first method of the prior art, since the leads of the taped axial lead electronic component are cut inside the tape, the leads are shortened by the length to be cut. Become. For this reason, re-taping cannot be performed unless re-taping from an axial lead electronic component having a wide tape interval, that is, an axial lead electronic component having a long lead wire, to a tape taping component having a narrow tape interval. As a specific example, for example, the present invention can be applied to the case where the tape spacing on both sides of the element portion is re-taped from 52 mm to 26 mm, but the 26 mm tape cannot be re-taped at the same interval. was there.

In the second method, the tape needs to be heated, and the structure is complicated. It is not preferable because there is a heat source in the apparatus. Since the softened adhesive has a high viscosity, the adhesive tends to remain attached to the lead wire even after being pulled out, and the adhesive adheres and accumulates on the transporting means, making it difficult for electronic components to come off easily. Had. As a result of various studies, the present inventor solidifies the pressure-sensitive adhesive at room temperature or by cooling, and even when the lead wire is pulled out in this state, the adhesive is hardened without causing any particular damage to the electronic component. Therefore, I knew that the amount of adhesive attached to the lead wire was also small. The present invention has been achieved based on this finding.

An object of the present invention is to provide a method and an apparatus for re-taping an electronic component with a lead, which can re-tape an electronic component with a short lead wire.
