Abstract

The invention discloses a real time following method for robot bend which comprises the following steps: step a, obtaining the position value of the end of the robot in the bend coordinate system at the bend start point; step b, receiving the detection result of a bend knife displacement detection device, obtaining the displacement of the bend knife in a preset sampling period according to the detection result, calculating the movement speed of the bend knife; step c, confirming the real time position value of the end of the robot in the bend coordinate system during the bend following process; step d, converting the real time position value of the end of the robot in the bend coordinate system into the real time position value in the world coordinate system, calculating the joint angle of the robot according to the real time position value in the world coordinate system, and sending the calculated joint angle of the robot to the robot driving device. A real time following device for robot bend is also disclosed. The high precision real time following operation for the robot during the bending process is achieved, the bending quality of the robot is raised and the work efficiency is improved.

Description

technical field

[0001] The present invention relates to robot technology, in particular to a robot bending real-time following method and device thereof. Background technique

[0002] With manual bending of the sheet, the worker needs to hold the sheet up and lift it up every time it is bent. This action is very laborious, labor-intensive, and low in production efficiency, and the human lifting motion trajectory cannot track the movement of the sheet well. , The bending effect is also difficult to guarantee. Robots are very good at repetitive work. After the bending path is completed, the robot can move according to the instructions to realize automated unmanned operations, which can improve production efficiency. Robot bending needs to move synchronously with the plate according to the movement of the bending knife, so as to avoid the deformation of the plate and poor bending quality caused by gravity during the bending process. During this process, the bending robot need...
