Abstract

The invention relates to a modularized series joint of a collaborative robot. The modularized series joint comprises a joint shell as well as a hollow motor, a harmonic reducer, an input shaft, an output shaft, a torque sensor, a brake, an absolute value encoder and a driver which are arranged in the joint shell, wherein the harmonic reducer, the hollow motor, the brake, the absolute value encoder and the driver are sequentially connected to the input shaft in series. A joint structure disclosed by the invention is more compact in structure, low in cost, higher in safety and reliability, ingenious, modularized and integrated; a brake structure is simple, convenient to install, reliable in brake performance, and stable; a force feedback system is sensitive in performance, stable, and high in reliability; and in addition, central hole wiring is used for wiring and arrangement, so that wire arrangement is more reasonable, and the wiring is more convenient.

Description

technical field

[0001] The invention relates to a mechanical arm joint structure, in particular to a modular serial joint of a collaborative robot. Background technique

[0002] When traditional industrial robots are gradually replacing monotonous, highly repetitive, and dangerous tasks, collaborative robots are slowly penetrating into various industrial fields and working together with humans. Collaborative robots are light-duty robots in industrial robots. In the past, industrial robots used machinery to replace labor and reduce labor costs. Collaborative robots mainly assist humans and work together with humans, and do not need to be isolated by safety fences. The precision achieved may keep humans out of dangerous environments and jobs. The joint structure of collaborative robot is the core component of collaborative robot, and its performance is very important in the whole process of collaborative robot movement. Its main features are modularization, flexibility, inte...
