Abstract
There is disclosed a scoring cutter for scoring printed circuit boards to a uniform thickness. The scoring cutter has top and bottom circular blades set to a gap and rotatable in opposite directions to each other. Resilient wheels, four in number, having diameters slightly larger than the blades, are mounted for rotation with respect to the blades, one on each side of each blade. A circuit board is fed between the blades, and the resilient wheels position the circuit board in the gap between the blades.
Claims13
A scoring cutter for scoring a board to a uniform thickness comprising first and second cutting means aligned and spaced apart a predetermined distance to define a gap wherein:
- (a) the first cutting means comprises:
- (i) a first circular cutting blade having a first blade diameter and fixed to a first shaft for rotation therewith;
- and
- (ii) a first pair of resilient wheels having a common first wheel diameter and a common first resilience, each mounted one on either side of the first cutting blade for rotation relative to the first cutting blade, wherein the first wheel diameter is equal to or greater than the first blade diameter,
- (b) the second cutting means comprises:
- (i) a second circular cutting blade having a second blade diameter and fixed to a second shaft for rotation therewith;
- and
- (ii) a second pair of resilient wheels having a common second wheel diameter and a common second resilience, each mounted on either side of the second cutting blade for rotation relative to the second cutting blade, wherein the second wheel diameter is equal to or greater than the second blade diameter.
