A multi-axis mechanical arm and robot

Abstract

The invention provides a multi-axis mechanical arm and a robot. A driving element is arranged on a platform at the bottom. A first arm and a second arm are free of the additional weight except for theweight of the first arm, the weight of the second arm and the weight of matched connecting rods, and are characterized in that the movement speeds of the tail ends are high. A rotation end and an autorotation end are installed at the tail end of the second arm, the higher motion freedom is achieved, and various operation requirements can be met. A driving assembly of the rotation end and a driving assembly of the autorotation end are also installed on the platform, the weight of the motion portion of the multi-axis mechanical arm is smaller than that of an existing mechanical arm module, andthe multi-axis mechanical arm is particularly suitable for rapid movement operation of a working tail end. A four-bar mechanism which is in a parallelogram shape is adopted, calculation of the position of the tail end of the second arm is easy, the programming difficulty of control software is greatly reduced, and popularization and usage of the multi-axis mechanical arm are facilitated.

Description

technical field [0001] The invention relates to the field of robots, in particular to a multi-axis mechanical arm and a robot. Background technique [0002] Robots can be divided into parallel robots and serial robots. Among them, the common type of serial robots is articulated robots. In common articulated robots, the driving components of each arm are installed on the joints connected to the forearm. As the number of arms increases, the load on each arm will increase accordingly, resulting in an increase in the volume of the driving power components of the arm and an increase in the movement speed of the arm. Problems such as slowing down and reducing the accuracy of the arm are not conducive to the high-speed and miniaturization of joint robots. [0003] Therefore, realizing the lightweight of the arm is a research direction for the high-speed movement of the robot end. Contents of the invention [0004] In order to realize the light weight of the robot arm, the embod...
