Abstract

An automatic soldering apparatus wherein a fixture is conveyed sequentially and endlessly by an elevation mechanism of a loading unit, soldering conveyors of a plurality of units that relate to the soldering operation, an elevation mechanism of an unloading unit, and return conveyors of units relating to the soldering operation; works are automatically fitted to the fixture by the loading unit, and while the fixture is being conveyed by the soldering conveyor of each of the units which relate to the soldering operation and are combined with one another suitably, whenever necessary, the soldering operation of the works and other operations associated therewith are carried out; and the unloading unit automatically recovers the works from the fixture and the empty fixture is returned to the loading unit by the return conveyors of the units relating to the soldering operation so that the works are again fitted to the fixture by the loading unit. The units relating to the soldering operation are partially removed, replaced or added, whenever necessary.

Claims3

Dependent claims

An automatic soldering apparatus for soldering a plurality of works while said works are being held in a plane by a fixture conveyed on an automatic soldering line, said fixture characterized by comprising:

an outer frame;
a grid formed inside said outer frame of said fixture and having crossing portions;
work receiving beds integrally mounted at said crossing portions of said grid in such a manner as to be positioned above said works at the time of soldering;
each of said work receiving beds of said fixture consisting of a round pipe member of a predetermined length and having work fitting grooves therein;
a work support frame mounted on said outer frame above said grid in such a manner as to be positioned below said grid at the time of soldering;
a hinge means connected between said outer frame and said work support frame to permit the latter to be pivoted relative to said outer frame between an open works receiving position and a closed works holding position;
work support means disposed on said work support frame to support said works from below when said support frame is in said closed position with said works fitted into said work receiving beds at the time of soldering;
and
latch means disposed on said outer frame and said work support frame and engageable and disengageable to releasably secure said work support frame in said closed position to permit said work frame to be positioned below said grid at the time of soldering and to permit said fixture to be turned upsie down to allow said work support frame to be opened upward for the fitting and removal of said work therein.
