Embodiment 1

[0044] figure 1 For the structural schematic diagram of the lightweight mechanical arm provided by the embodiment of the present invention, please refer to figure 1 As shown, the lightweight mechanical arm of this embodiment includes a base 1, a first arm body 2, a second arm body 3, a third arm body 4, a fourth arm body 5, a fifth arm body 6, and a sixth arm body 7. The end effector 8, the first modular joint, the second modular joint, the third modular joint, the fourth modular joint, the fifth modular joint, the sixth modular joint, and the seventh modular joint, The first modular joint, the second modular joint, the third modular joint, the fourth modular joint, the fifth modular joint, the sixth modular joint and the seventh modular joint all have rotational degrees of freedom, so The base, the second arm 3, the fourth arm 5, and the sixth arm 7 all have hollow cavities, the first modular joint is located in the hollow cavity of the base 1, and the second modular joint ...

Embodiment 2

[0058] This embodiment provides a robot, which includes the light-weight mechanical arm described in Embodiment 1.

[0059] The light-weight mechanical arm of the robot in this embodiment uses the first modular joint, the second modular joint, the third modular joint, the fourth modular joint, the fifth modular joint, the sixth modular joint and the seventh modular joint The modular joints are arranged in the hollow cavity of the second arm, the fourth arm and the sixth arm, which reduces the overall weight of the mechanical arm and improves the load and self-weight ratio of the mechanical arm. The modular joints are self-contained and can be Direct overall disassembly and assembly avoids the limitation of the outer frame size constraints when installing joint parts in the traditional way, which is conducive to quick replacement and installation, and is also convenient for maintenance.

Abstract

The invention discloses a light-weight mechanical arm and a robot having the same. The light-weight mechanical arm includes a base, a first arm body, a second arm body, a third arm body, a fourth arm body, and a fifth arm body , the sixth arm body, the end effector, the first modular joint, the second modular joint, the third modular joint, the fourth modular joint, the fifth modular joint, the sixth modular joint and the seventh modular joint Joints, the base, the second arm, the fourth arm, and the sixth arm all have hollow cavities, the first modular joint is located in the hollow cavity of the base, the second modular joint and the third modular joint are located In the body of the second arm, the fourth modular joint and the fifth modular joint are located in the fourth arm body, and the sixth modular joint and the seventh modular joint are located in the sixth arm body. The overall weight of the robot arm is reduced, and the load-to-weight ratio of the robot arm is improved. The modular joints are self-contained and can be directly disassembled and assembled as a whole.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a light-weight mechanical arm and a robot with the same. Background technique [0002] At present, China has become an important market for industrial robots in the world, and robots are gradually expanding to semiconductor (3C), service, medical and other industries outside the traditional automobile and consumer electronics fields, becoming a new growth point for the industry. While the new industry field has higher requirements on robot weight, self-weight-to-load ratio, volume, and transmission accuracy, it also creates new demands in the field of human-machine collaboration. Therefore, the development of a lightweight manipulator oriented towards human-machine collaboration and having a large weight-to-load ratio, small size, and high transmission accuracy has broad market application prospects. [0003] The invention patent with the publication number CN107972021A discloses...
