Abstract

The invention discloses a high-speed multi-degree-of-freedom flexible and wear-free transportation system, comprising: a parallel transportation platform, which can move under the action of a magnetic field, and the parallel transportation platform has switchable lifting movement modes, rotation movement modes, and tilting movements mode; the parallel transport platform can descend to a singular posture close to the parallel transport platform when it is not working; the magnetic levitation transmission track, the parallel transport platform is set on the magnetic levitation transport track, and the magnetic levitation transport track includes a plurality of connected planar modules to generate drive The magnetic field of the parallel transport platform movement; the starting device, the starting device is arranged on the magnetic levitation transmission track, and the starting device is used to drive the parallel transport platform away from the singular posture. The invention moves on the magnetic levitation transmission track through the parallel transport platform, without friction and wear, which is beneficial to realize high-precision and high-dynamic transport and positioning functions, and has multiple motion modes of lifting, rotating, and tilting, and has high flexibility.

Description

technical field [0001] The invention relates to the technical field of production line transportation, in particular to a high-speed multi-degree-of-freedom flexible and wear-free transportation system. Background technique [0002] With the development of Industry 4.0, the automation of material transportation is an important part of industrial automation. Traditional conveyor belts and rigid transmission lines have poor flexibility and are difficult to adapt to the trend of customized and flexible production. [0003] At present, the commonly used AGV transportation has good flexibility and flexibility, but the dynamic characteristics of AGV transportation are poor, and it is prone to wear and tear, resulting in high maintenance costs. The traditional magnetic levitation transportation system has better precision and dynamic characteristics, but it can only realize plane movement, and cannot realize large-scale three-dimensional movement such as lifting, rotating, and tilt...
