Anti-collision and Precise Positioning for AMHS Overhead Cranes in High-Speed Operation

In the wafer fab cleanroom—where every inch of space is precious—AMHS system OHT cranes must operate densely at speeds of up to 3–5 meters per second along a complex network of overhead tracks, efficiently handling the flow of wafer cassettes (FOUPs). Should a collision or drop occur, not only would expensive wafers be damaged, but the entire production line could come to a standstill, resulting in immeasurable losses. Traditional obstacle-detection sensors often either are too bulky to be easily integrated into the compact crane body, or have low scanning frequencies that lead to delayed responses at high speeds. Moreover, these sensors struggle to accurately detect black or highly reflective foreign objects on the tracks, posing significant safety risks.

Photovoltaic Wafer Handling AGV: High-Precision Navigation and Three-Dimensional Safety Protection

In the intelligent production workshop for photovoltaic cells, AGVs are responsible for handling the high-value, highly fragile silicon wafer baskets. Due to the compact nature of the workshop environment, machinery often features suspended displays or operating consoles, and AGVs themselves tend to be relatively tall—typically standing over 1.5 meters in height. If radar sensors were installed only at the bottom of the AGV, this would create a significant “upper-body blind zone.” Should an AGV’s upper body collide with anything, not only could expensive production equipment be damaged, but the intense vibrations could also cause the entire stack of silicon wafers to shatter, resulting in severe economic losses. Moreover, AGVs must precisely dock with machine conveyor belts to within millimeter-level accuracy, placing extremely stringent demands on navigation precision.
