Abstract

Disclosed is a tool designed to deburr printed circuit panels. The panels have one or more punched notches around their periphery that serve to locate them in subsequent operations. The punching of the notches leaves burrs on the top and bottom of the panels that must be removed.

Auto-Adjust Panel Deburr Tool

      Disclosed is a tool designed to deburr printed circuit panels.
The panels have one or more punched notches around their periphery
that serve to locate them in subsequent operations.  The punching of
the notches leaves burrs on the top and bottom of the panels that
must be removed.

      As shown in the Figure, the tool is comprised of a bottom
assembly (1) that is firmly attached to a work table or surface.
Directly above bottom assembly (1) is top assembly (2).  Pressed into
bottom assembly (1) are two shafts (3).  Pressed into top assembly
(2) are two linear bearings (4) located so as to align with shafts
(3).  Top assembly (2) is thereby free to translate vertically in
relation to bottom assembly (1) in a coplanar manner.

      Located at the front or entrance of the tool are panel ramps
(5) and (6).  Ramps (5) are firmly attached to bottom assembly (1)
and are flush with its top surface.  Ramps (6) are firmly attached to
top assembly (2) and are flush with its bottom surface.

      Pressed into top assembly (2) are two ball bearings (7).  Into
ball bearings (7) is pressed shaft (8).  Attached to the bottom end
of shaft shaft (8) is top cutter (9).  The outer and bottom surfaces
of top cutter (9) are cutting surfaces.  The bottom surface of top
cutter (9) is flush with the bottom surfaces of top assembly (2) and
ramps (6).

      Opposite to top cutter (9) is bottom cutter (10).  The outer
and top surfaces of bottom cutter (10) are cutting surfaces.  The top
surface of bottom cutter (10) is flush with the top surfaces of
bottom assembly (1) and ramps (5).

      Bottom cutter (10) is attached to a shaft and two ball bearings
(not shown) in a similar manner as top cutter (9) is attached to
