Precision robot

Abstract

The invention provides a precision robot. The robot comprises a base assembly, a big arm assembly, a forearm assembly and a control system; one end of the big arm assembly is rotationally arranged on the base assembly; a first angle encoder coaxially rotating with the big arm assembly is arranged on the base assembly; one end of the forearm assembly is rotationally arranged at the other end of the big arm assembly; a second angle encoder coaxially rotating with the forearm assembly is arranged at the other end of the big arm assembly; the other end of the forearm assembly is connected with a load; the first angle encoder and the second angle encoder are in signal connection with an input end of the control system; and the base assembly and the big arm assembly are in signal connection with an output end of the control system. With the precision robot, the position and the motion track of a mechanical arm can be detected by the control system online in real time, so that full-closed loop control on input and output is realized, and the motion speed and precision of the robot are greatly increased.

Description

technical field [0001] The invention relates to the technical field of robots, and more specifically, to a precision robot. Background technique [0002] Robot is a collection of mechanical engineering, electronic engineering, computer technology, automatic control and artificial intelligence and other scientific research results. It is a typical representative of mechatronics technology and the most active field of contemporary scientific and technological development. In recent years, robot technology has developed very rapidly, and robots for various purposes have been widely used in various fields. [0003] The existing tandem industrial robots have been widely used in the manufacturing industry, including stamping, handling, painting, palletizing, polishing and other operations. However, in some occasions where the positioning accuracy is high, the trajectory accuracy is high, and the work efficiency is high, the existing tandem robots will not be able to meet the requ...

However, in some occasions with high positioning accuracy, high trajectory accuracy, and high work efficiency, the existing tandem robots will not be able to meet the requirements

Since the vast majority of serial industrial robots currently use an open-loop system, that is, the robot moves or works after receiving the pulse command from the control system, and does not feed back the position of the robotic arm of the robot to the control system. Therefore, the control system cannot It is difficult to control the robot when the trajectory or position of the robot is known, so it is difficult to ensure the positioning accuracy and trajectory accuracy of the robot, which makes it difficult for the robot's accuracy to meet the product accuracy requirements
