BELT DRIVE BELT BITE PREVENTION DEVICE OF CARTESIAN COORDINATES ROBOT

摘要

The present invention relates to a belt gearing preventive device of a belt driving orthogonal coordinate robot. The present invention comprises: a guide rail of a coordinate robot; a driving body which is reciprocally disposed on the guide rail; and belt gearing preventive blocks which are separated at both sides of the driving body and are reciprocally disposed along the guide rail, wherein one end part of a wire is respectively connected to both sides of the driving body and the other end part of the wire is respectively fixated to a base of the coordinate robot via a belt gearing preventive block. According to the present invention, belt drooping and gearing phenomenon generated by relatively long stroke in reciprocating movement of a driving body along the guide rail can be prevented, thereby preventing immovability of the driving body and preventing the generation of friction noise and belt particles due to abrasion.
