Abstract

Disclosed is a machine that will make a smooth 45o cut on each of the four corners of a large panel after the panel has been cut to size on a flash cutting machine. The flash cutter leaves a sharp square corner after is has beveled the edges of the panel and this machine breaks each of the corners with a 45o machined cut while providing a large cut at one of the four corners to serve as an orientation cut. The design of the Corner Cut Module is such that it can be made to fit on top of a two-foot length of conveyor that is normally used to transport product out of the flash cutter, thus taking no more floor space than originally needed for the flash cutting machine.

Circuit Board Corner Cut Module

      Disclosed is a machine that will make a smooth 45o cut on each
of the four corners of a large panel after the panel has been cut to
size on a flash cutting machine.  The flash cutter leaves a sharp
square corner after is has beveled the edges of the panel and this
machine breaks each of the corners with a 45o machined cut while
providing a large cut at one of the four corners to serve as an
orientation cut. The design of the Corner Cut Module is such that it
can be made to fit on top of a two-foot length of conveyor that is
normally used to transport product out of the flash cutter, thus
taking no more floor space than originally needed for the flash
cutting machine.

      The Corner Cut Module is a self-contained machine that mounts
to the top of the exit conveyor on the flash cutter. A panel
traveling on the conveyor is sensed at the optical detector (5) and
the conveyor is stopped.  At this point a lift mechanism pulls the
panel up into position in the Corner Cut Module and clamps it prior
to cutting the corners.  The machine has four cutters driven by small
air motors (2) that are moved across the corners of the panel on lead
screw drives, thus removing the corners of the circuit board (4).
Once the cuts are made the lead screw drives are retracted to their
original position enabling the deburr knives shown in the enlarged
view at number (3) to be dra...
