High Precision Rotary Voice Coil Motor For Semiconductor Micro Bulk Feeding

The rotor coil of a rotary voice coil motor is lightweight, with a short response time and high frequency. Swing angle: 1-100 degrees; torque: 1-50 N·m. In semiconductor micro bulk feeding equipment, rotary voice coil motors are used for precise positioning and non-damaging transport of micro components. For fragile materials such as 0.2mm-12mm micro bulk materials and wafer Die in semiconductor packaging, the rotary voice coil motor drives them through a non-contact force field. Combined with PID algorithms, it achieves precise control of amplitude and frequency at the micron level, enabling the materials to perform complex rotational actions such as flipping and gathering. This keeps the materials in a 'floating' state of movement, eliminating mechanical shear wear on component surfaces from the physical source. The material damage rate is controlled below 0.01%, while also achieving millisecond-level decoupling and separation of irregular parts, providing clean and unobstructed material supply for subsequent chip assembly.
