Problems solved by technology

[0003] In the prior art, the transmission mechanism of a parallel robot usually includes connection loads such as couplings, racks, and reducers. These connection loads will increase the overall volume of the parallel robot, thereby reducing the structural compactness of the parallel robot.
In addition, there are unavoidable uncontrollable factors such as gaps, elastic deformation or friction damping inside the traditional connection load. During use, the above uncontrollable factors will affect the motion accuracy and response characteristics of the parallel robot, which cannot meet the actual requirements. High-precision work requirements

Abstract

The invention provides a small parallel robot driven by linear motors. The small parallel robot comprises a rack, a fixed assembly, a movable platform and three driving units. The fixing assembly comprises a first fixed platform and a second fixed platform, and the first fixed platform is arranged above the second fixed platform. The driving unit comprises a shell, a linear motor assembly, a guide rail, a connecting block and a connecting rod set, the linear motor assembly and the guide rail are both arranged in the shell, and the included angle between the length direction of the guide rail and the plumb line direction is 45 degrees. The connecting block is arranged on the guide rail, and the linear motor assembly drives the connecting block to slide on the guide rail. One end of the connecting rod set is hinged to the connecting block, and the other end of the connecting rod set is hinged to the movable platform located below the fixing assembly. According to the small parallel robot driven by the linear motor, the structural compactness and motion precision of the parallel robot can be improved, and therefore the actual use requirement is met.

Description

technical field [0001] The invention belongs to the field of parallel robots, in particular to a small parallel robot driven by a linear motor. Background technique [0002] A parallel robot is a closed-loop mechanism that is driven in parallel and has two or more degrees of freedom. It is widely used in precision manufacturing, medicine and electronics at this stage. With the continuous improvement of automation technology, people put forward higher requirements for the precision of parallel robots. Therefore, the size and motion accuracy of parallel robots have gradually become important indicators to measure their performance. [0003] In the prior art, the transmission mechanism of the parallel robot usually includes connection loads such as couplings, racks, reducers, etc. These connection loads increase the overall volume of the parallel robot, thereby reducing the structural compactness of the parallel robot. In addition, there will inevitably be uncontrollable facto...
