AI Technical Summary

Technical Problem

Existing pick and place robots face issues with cogged belt systems, including size and alignment problems due to increased load and velocity, leading to uneven sliding and noise, which are exacerbated by the use of wider belts or larger pulleys.

Method used

A movement system using cables instead of belts, with pulleys arranged in a balanced configuration to enable smooth, alternating translation of the robot along a guide rail, reducing size and noise while maintaining fluid movement.

Benefits of technology

The cable-based system provides a compact, quiet, and efficient translation mechanism that minimizes wear and alignment errors, ensuring smooth operation and extended cable life.

Abstract

The motion system (100) of a robot (RT) in alternating translation along a translation direction (Z) comprises: a carriage (1) supporting the robot (RT); a longitudinal sliding guide rail (10) on which the carriage (1) is slidably mounted; and means of movement (2) of the carriage (1) along the guide rail (10). The means of movement (2) comprise: a first free pulley (21) with a first annular groove (210); a second free pulley (22) with a second annular groove (220); a drive pulley (23) with a third annular groove (231) and a fourth annular groove (232); a first cable (24), restricted to a first point on the carriage (1) and to a first anchor point (A1) present on the drive pulley (23); a second cable (25), restricted to a second point of the trolley (1) and a second anchor point (A2) present on the drive pulley (23).
