Horizontal articulated industrial robot body with 4-axis configuration combining high-speed, high-precision positioning in XY plane and vertical lifting motion. Specialized for electronic component assembly, PCB mounting, small parts pick & place, and palletizing operations, achieving high tact time with compact installation footprint. Unlike multi-joint robots, end-effector attitude control is limited but excels in speed and precision for planar operations. Available in integrated control box type and separate type, with payload capacity ranging from 1kg to 20kg as mainstream products. Clearly distinguished from Cartesian robots and Delta robots in operating principles and application uses.
