Title:
AUTOMATIC POINT SOLDERING MECHANISM
Document Type and Number:
Japanese Patent JPS635869
Kind Code:
A
Abstract:

PURPOSE: To always feed a string solder at a fixed position for a soldering iron tip even if the upper and lower positions of a soldering substrate vary, by performing the positioning of a solder supporting part by the stopper in the space with a soldering iron tip supporting part and fixing the relative position of the both supporting parts.

CONSTITUTION: With the actuation of an air cylinder 3 a soldering iron tip and solder supporting parts 11, 10 are descended symmetrically by being pushed down with springs 18, 19 and a string solder 2 is pinched between the soldering iron tip 1 and a pad lead 4. The soldering iron tip 1 is lifted by a spring 5 just before its abutting the lead 4 and finally positioned by the stopper 6, which is adjusted so that the soldering iron tip 1 and solder 2 may become an optimum positional relation in advance and the positional relation of the both is always made constant. The supporting parts 11, 10 are pressed via springs 18, 19 by the cylinder 3 and when the soldering iron tip 1 is abutted to a substrate 14 before the stroke end of the cylinder 3, the springs 18, 19 are contracted and the soldering iron tip stops at that time. The soldering iron tip is therefore following up the substrate 14 at all times even if the soldering position moves up and down by the deflection of the substrate 14, etc. and the solder 2 follows the soldering iron tip as well, so it becomes feedable to the constant position always.
