Conveyor Clip for Process Baths

      Described is an improved design of construction clip used in
conveyors for manufacturing processes on printed circuit panels (PC)
over fluid baths.

      A single injection moulding replaces several conventional
discrete precision components.  A plurality of one part number
becomes the major construction element of conveyor matrices.  The
design allows easy access or replacement of a clip without stripping
down the whole assembly.  Benefits result in reliability, reduced
down time and lowered initial unit costs.

      Fig. 1 depicts in plan view a conveyor lattice of shafts (3)
spaced and separated by separator clips (1) running at right angles
to the shafts (3).  Pinch rollers (7) are mounted on the shafts (3)
rotated by external motors driving the PCs (11) across the conveyor
face.

      Two such arrangements, one upper and the other lower parallel
to each other are positioned with a controlled lateral space between
them to accept the passage of printed circuit (PC) panels (11) which
are conveyed by counter rotating upper and lower pinch rollers (7).
In passage across the conveyor the PCs are treated by sprayed fluids
from above and below with surplus liquid draining into a sump below
the conveyor.  Because some fluids used may cause corrosion,
sediment, or gum deposits, materials used in the conveyor should be
as chemically inert as possible but when needed for periodic
maintenance, cleaning or wear the parts must by quick and easy to
remove and reassemble without the complete dismantling of the whole.

polypropylene or...
