AI Technical Summary
In the existing technology, the cutting direction of the deburring drill is perpendicular to the direction of burr generation at the intersection point. After the cutting force is decomposed, the effective cutting force acting on the substrate is small, which causes the deburring drill to generate burrs again at the exit edge, increasing production costs and reducing production efficiency.
By detecting the connecting holes formed by intersecting slots, the first intersection point without substrate support is determined. Based on the coordinates of this point and the width of the slot, the position and size of the deburring hole are determined, and an additional deburring drill is added to remove burrs. The cutting force decomposition is optimized to increase the effective cutting force.
This technology enables the removal of burrs at cross-slot holes in a single cut, reducing production costs and improving production efficiency while ensuring good cutting performance and the solderability and conductivity of the circuit board.
