Abstract

Automated material handling systems (AMHSs) are widely utilized in general manufacturing processes. The precision motion control and wear resistance of rolling parts of an AMHS are important factors to ensure sufficient reliability of the final product. Polyurethanes are widely used in the manufacturing process due to their superior damage resistance and adequate rolling friction properties. In this work, friction and wear behaviors of polyurethane O-ring rollers sliding against a glass plate specimen were investigated with respect to sliding speed, temperature and relative humidity. A pin-on-reciprocating sample tribotester in an environmental chamber was used to assess the friction and wear properties of the polyurethane O-rings. It was found that the wear resistance increased for higher sliding speed, higher temperature, and lower relative humidity conditions. The results of this work are expected to provide optimized O-ring transfer equipment operating conditions to improve the productivity of the TFT-LCD manufacturing process.
