Abstract

Disclosed is an apparatus used to punch vias in thin sheets of uncured (green) ceramic materials. This apparatus punches 4 sheets simultaneously, under software control and with high precision. The apparatus uses a high-speed punch actuator which allows the tool to punch vias while the sheet is in motion, resulting in high production rates.

Flex Punch Production Tool

      Disclosed is an apparatus used to punch vias in thin
sheets of uncured (green) ceramic materials.  This apparatus punches
4 sheets simultaneously, under software control and with high
precision.  The apparatus uses a high-speed punch actuator which
allows the tool to punch vias while the sheet is in motion, resulting
in high production rates.

      The isometric figure represents the mechanics of the tools that
are currently on line.  The operator begins by placing one green
sheet on each of the four vacuum plates 1. While loading, the
sheet-supports 2 are raised into position by bellcrank and roller arm
11 to support the sheets.  Then, the vacuum is switched on and the
sheets are held firmly, ready for processing.  The sheets are then
moved with computer software by the "x" and "y" stages 3 and 4.  As
the sheets move, the punch-drive-coil 5, also software driven, cycles
the punch components to produce the vias.  The "c" arm 6 supports the
punch components with high precision and maintains the proper gap
between the punch and die utilizing interchangeable shims 9 to
accommodate sheets of different thicknesses.  The flex post 7 is
utilized for accurately positioning the punch components in "x" and
"y" with respect to each green sheet individually.  This is
accomplished by turning the fine pitch screws 10.  An anti-crash post
8 safeguards the precision punch components under fault conditions by
contacting a slightly undersiz...
