Collaborative robot modular joint

Abstract

The invention provides a collaborative robot modular joint. The collaborative robot modular joint comprises a joint body, an output flange, a speed reducer assembly, a band-type brake assembly, an absolute value encoder assembly, a built-in driving plate assembly and a motor assembly which are arranged in the joint body; the output flange is a flange with an O-shaped groove and a hollow shaft, theO-shaped groove is used for oil seal of the speed reducer assembly, the hollow shaft is fixedly connected with the output end of a speed reducer body, and the hollow shaft is used for being connectedwith other joints; and the speed reducer assembly comprises the speed reducer body and a speed reducer input shaft, and the speed reducer input shaft is integrally designed with a speed reducer wavegenerator in the speed reducer body. The cooperative robot modular joint has the characteristics of being good in replaceability, capable of realizing mass production, high in cooperative performanceand high in safety.

Description

technical field [0001] The invention relates to the technical field of collaborative robots, in particular to a modular joint of a collaborative robot. Background technique [0002] With the proposal and widespread promotion of "Industry 4.0" and "Made in China 2025", the state and enterprises pay more attention to the development of key technologies for intelligent manufacturing. Traditional robots have been widely used in various industries, and can gradually replace monotonous, highly repetitive, and dangerous tasks in the production process, and have achieved great results, improving the degree of automation and reducing labor costs. [0003] With the continuous development of science and technology, new industries require robots to be able to realize human-machine cooperation, that is, robots can be as flexible as humans, realize dragging and teaching, and cooperate with humans to complete some special tasks, and do not need to use safety fences for isolation, so as to ...

AI Technical Summary

Problems solved by technology

[0008] (2) Problems with the input shaft of the reducer

[0009] Due to the low processing accuracy and poor assembly of the input shaft of the reducer, it is necessary to control the processing accuracy and assembly accuracy, and to add additional auxiliary support bearings, which has the problem of not compact structure

[0010] (3) Brake problem

[0011] The main problems of the brake are that the standard product has high requirements on machining accuracy, high operating noise, high heat generation, high price and uncompact structure.

[0012] (4) Servo drive board problem

[0013] The problem of the servo drive board is mainly reflected in the difficulty of wiring inside the external drive, which requires a built-in drive board

[0014] (5) Encoder packaging problem

[0015] Dual encoders need to be packaged, especially single-turn absolute encoders have relatively high requirements for packaging, and require high-level debugging personnel, which is difficult to mass-produce
