Vision-based robot posture adjustment device and method

Abstract

The invention discloses a vision-based robot posture adjustment device and method. The vision-based robot posture adjustment device comprises two connecting plates. Two parallel conveying shafts are rotatably connected between the two connecting plates. The two conveying shafts are connected through a conveying belt. One end of one conveying shaft penetrates through one connecting plate and extends to one side of the connecting plate, and a first rotating wheel is fixed to one end of the conveying shaft. According to the vision-based robot posture adjustment device and method, intelligent grabbing can be achieved, a robot is in signal communication with vision cameras through a PLC system, and the grabbing posture of the robot is adjusted based on the reference position of the robot according to workpeiece posture information provided by the vision cameras, so that the relative positions of a gripper of the robot and a workpiece are fixed every time grabbing is conducted, and accordingly, it is ensured that the placing positions and postures of workpeice are constant even if the positions of the grabbed workpieces are different; and the vision-based robot posture adjustment deviceand method are suitable for being applied to the high-precision automation industry.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a vision-based robot pose adjustment device and method. Background technique [0002] In the automation project, the parts are manually placed on the starting end of the conveyor belt. After the conveyor belt runs to the range of the camera and the robot’s travel range, the sensors on both sides of the conveyor belt detect the arrival of the workpiece and the conveyor belt stops. The robot needs to grab the small pieces on the conveyor belt, and then The workpiece is transported to a specific fixture and placed on it. Due to the high requirements for pose accuracy during placement, it is necessary to ensure that the positions of the workpiece and the gripper are relatively fixed each time the robot grabs the workpiece on the conveyor belt. [0003] The position of the workpiece placed on the conveyor belt manually is uncertain, and the sensor detects the workpiece in motion and s...

AI Technical Summary

Problems solved by technology

[0003] The position of manually placing the workpiece on the conveyor belt is uncertain, and the sensor detects the moving workpiece and stops the conveyor belt every time the workpiece position will be slightly deviated

These two deviation factors make it impossible for the robot to grasp the workpiece with a fixed position and posture to be relatively consistent each time. Therefore, we propose a vision-based robot position adjustment device and method to solve the above problems
