Multi-joint manipulator and mechanical arm

Abstract

The multi-joint manipulator comprises a supporting seat, a rotating disc is arranged at the upper end of the supporting seat, a hydraulic cylinder is fixedly connected to the center of the upper end of the rotating disc through a base, a supporting block is fixedly connected to the output end of the hydraulic cylinder, and a supporting column is vertically fixed to the center of the upper end of the supporting block; a mounting plate is fixedly connected to one side of the upper end of the supporting column, a base is fixedly connected to one side of the mounting plate, a moving plate is arranged on one side of the base, a through opening is formed in the mounting plate, a double-end motor is fixedly connected into the through opening through a mounting base, and a pushing mechanism is arranged on the side, close to the base, of the double-end motor. The side, away from the base, of the moving plate is fixedly connected with a mounting shell through a plurality of fixing columns, a moving mechanism is arranged on the side, close to the mounting shell, of the double-end motor, and one side of the moving mechanism is located in the mounting shell. The two clamping plates are used for assisting the suction cups to transport objects, the stability of the objects is guaranteed, the objects are prevented from falling off, and the safety is higher.

Description

technical field [0001] The invention relates to the field of manipulators, in particular to a multi-joint manipulator and a manipulator. Background technique [0002] A manipulator is an automatic operating device that can imitate certain movement functions of the human hand and arm to grab, carry objects or operate tools according to a fixed program. The feature is that various expected operations can be completed through programming, and the structure and performance have both the advantages of man and robot. It is the earliest industrial robot and also the earliest modern robot. It can replace the heavy labor of people 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, etc. , light industry and atomic energy. [0003] Existing manipulators generally have clamping and adsorption types. The adsorption type uses vacuu...

AI Technical Summary

Problems solved by technology

[0004] In view of the prior art, the manipulator generally has clamping type and adsorption type. Using a vacuum chuck or a magnetic chuck to pick up the object, although it is faster to pick up, but once an accident occurs during the adsorption process, it will cause the object to be separated. The connection of the manipulator is not tight enough, which will cause some objects to fall and cause damage to the objects. At the same time, the existing manipulator has a complex structure and high production costs. The present invention provides a multi-joint manipulator and a manipulator
