Timing Belt Drive Type Cartesian Coordinate Robot

摘要

The present invention relates to a timing belt driving type rectangular coordinate robot and comprises a motor (5) for providing power to a conveying body (3) moving linearly along a guide (2) on a base (1) Is provided at one end of the base 1 separated from the conveying body 3 and is provided with a plurality of inner timing belts 17 and 18 for conveying and guiding the conveying body 3 A motor housing 4 is attached to one end of the base 1 and a motor 5, a drive pulley 6, a drive timing pulley 7, a deceleration pulley 8, a driven pulley 9 and the main shaft 10 are coupled to each other and a difference in height is given to the inside timing belts 17 and 18 to eliminate interference so that the auxiliary shafts 14 and 15 provided in the conveying member 3 And the contact angles of the inner timing belts 17 and 18 are increased. The present invention maximizes the contact angle between the first auxiliary shaft 14 and the second auxiliary shaft 15, minimizing the change in the tension of the belt and enabling accurate power transmission. In particular, Since the timing belt 7 for the second auxiliary shaft is used independently, it is possible to achieve excellent positioning as well as improvement in the overall service life. The stick slip phenomenon is eliminated by the guide pulley provided on the second auxiliary shaft, And the like.
