Mold Air Hole Drilling Robot System

Mold Air Hole Drilling Robot System

This technology implements a 6-DOF air hole drilling system optimized for 3D irregular mold surfaces by combining a sliding joint (2-DOF) that moves along a curved rail based on a spherical coordinate mechanism with a rotary joint (4-DOF) that controls the drilling tool.

Conventional radial drilling machines are limited to vertical machining, making them unsuitable for irregular curved surfaces. Relying on manual labor leads to reduced efficiency, increased processing time, bottlenecks, and inconsistent production quality.

This technology positions the manipulator on a curved coordinate system using cross-arranged curved rails and sliding joints. It performs automated drilling by driving rotary and linear joints based on control signals derived from drawing analysis and simulation. Each joint is equipped with an electronic brake to maintain high rigidity during drilling. Applicable to industrial robots and automation systems, it improves the reliability of mold air hole machining and production speed by moving the robot manipulator along the curved coordinate system.
