Stretching mechanism and high-vacuum mechanical arm

Abstract

The embodiment of the invention provides a stretching mechanism and a high-vacuum mechanical arm, the stretching mechanism is applied to the high-vacuum mechanical arm and used for being connected with a mechanical arm and a driving mechanism, the stretching mechanism comprises a plurality of movable arms, the movable arms are arranged in a line shape and movably connected with one another in a sleeving mode in sequence, and the movable arms are connected with the driving mechanism in a sleeving mode. Wherein the movable arm positioned on the innermost side is connected with the driving mechanism and the manipulator; the first sliding assembly comprises a first sliding piece and a second sliding piece which are arranged on the two movable arms in a matched mode respectively, the two movable arms are connected in a sleeved mode, and the first sliding piece and the second sliding piece are matched with each other so as to reduce resistance generated when the movable arms slide in the length direction of the movable arms. The stretching mechanism can be used in a high-vacuum environment, the sliding resistance is small, and the stretching range is widened.

Description

technical field [0001] Embodiments of the present invention relate to the field of robotic arms, and in particular, to a stretching mechanism and a high-vacuum robotic arm. Background technique [0002] A manipulator is an automatic operation device that can imitate some action functions of human hands and arms to grab, carry objects or operate tools according to a fixed program. Its characteristics are that it can be programmed to complete various expected operations, and it has the advantages of both human and robotic machines in structure and performance. [0003] The manipulator is the earliest industrial robot and the earliest modern robot. It can replace the heavy labor of humans to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety. Therefore, it is widely used in machinery manufacturing, metallurgy, Electronics, light industry and atomic energy sectors. [0004] In the process of real applicati...

AI Technical Summary

Problems solved by technology

[0005] At present, some operations require the robotic arm to be carried out in a high-vacuum environment, but lubricating materials such as lubricating oil cannot be used in a high-vacuum environment, so the robotic arm cannot be stretched to the target position as required, and the stretching process is not enough Smooth, prone to stuttering

At the same time, it will cause a large error in the operation of the drive device in the robotic arm, which will reduce the performance of the robotic arm and the user experience
