Novel robot arm

Abstract

The invention discloses a novel robot arm. The robot arm comprises a shoulder structure, a big arm, an elbow structure, a forearm and a wrist structure; the shoulder structure is connected with the big arm; the big arm is connected with the elbow structure; the forearm is arranged below the elbow structure; the wrist structure is connected below the forearm; the shoulder structure comprises a shoulder joint speed reducer, a shoulder joint forward-and-backward movement driving motor, a shoulder joint forward-and-backward movement driving gear pair and a shoulder joint leftward-and-rightward movement driving motor; the elbow structure comprises an elbow joint and an elbow joint driving motor; the wrist structure comprises an electric conduction slip ring connected with the forearm and a connecting flange below; and the connecting flange and a manipulator are detachably mounted together. According to the novel robot arm, through the structural design, the electric conduction slip ring isadded to the wrist structure, twisting and winding of cables during movement of a mechanical arm can be prevented, ageing can be decelerated, replacement and overhauling can be facilitated, meanwhile,the shoulder size can be reduced, and the use cost of the robot arm is reduced.

Description

technical field [0001] The invention relates to the field of robots, in particular to a novel robot arm. Background technique [0002] With the continuous improvement of people's education level, fewer and fewer people are willing to engage in low-tech, low-value-added service industries, such as welcome, consultation, reception, etc.; the development of robots is not limited to early industrial robots, service The development of robots is a trend at this stage. The development of service robots has brought more convenient and comfortable services to humans. Due to the intensification of the aging of the global population, the market for service robots is broad, and service robots have gradually become a hot spot for research and application. [0003] With the rapid development of robot technology, people's requirements for the functions of robots have increased again and again, and they are no longer satisfied with the traditional clumsy concept. For this reason, the bio...

AI Technical Summary

Problems solved by technology

[0004] For service robots, a suitable humanoid robot arm is very important, but many existing robot arms have some deficiencies. At present, there are many cables in the robot arm structure, and when the robot arm rotates, often The cable will be entangled due to multiple rotations, which is not conducive to other extended applications. At the same time, the line is easily damaged due to friction and aging, and maintenance is difficult, which greatly increases the use cost of the robot arm and is difficult to meet the current market demand.
