Embodiment Construction

[0016] In order to achieve the above-mentioned purpose, the technical means and effects thereof adopted by the present invention are now given as preferred embodiments, and are described as follows in conjunction with the accompanying drawings.

[0017] see figure 2 , is a schematic diagram of the recalibration robot arm of the present invention. The present invention re-calibrates the robot arm 20 installed in the working environment, wherein one end of the robot arm 20 is a fixed body 21 with an arm reference coordinate M, and the movable part 22 at the other end of the robot arm 20 An on-arm camera 23 is installed. Through the control device 24 of the robot arm 20, the camera 23 on the arm is instructed to capture images, and according to the analysis and processing of the captured images, the multiple toggle joints 25 driving the robot arm 20 are controlled, and the movable part 22 is guided to approach the working environment. The workpiece 28 of the working machine 26...

Abstract

The invention discloses an automatic re-correction method of a robot arm. The automatic re-correction method comprises the steps robot arm re-correction operation is automatically started at preset time; a camera on a moving arm is controlled to be at a preset azimuth; an image of a simple pattern fixed relative to a robot arm body is focused and captured; according to the captured image, a detection azimuth of a movable part of the robot arm is calculated, and an error between the detection azimuth and the preset azimuth is compared, so as to correct the error of the robot arm.

Description

technical field [0001] The invention relates to a method for recalibrating a robot arm, in particular to a method for the robot arm to automatically start a recalibration operation at a predetermined time to preventively correct the movement error of the robot arm. Background technique [0002] With the rapid development of industrial production technology, factory automation uses the vision device of the robotic arm to locate the position and posture of the workpiece, guide the robotic arm to automatically and accurately grab the workpiece, and carry out assembly and manufacturing to improve the efficiency of precision and rapid production. The main key that affects the automatic and precise movement of the robot arm is the guiding vision device. Using the vision device to correct the robot arm and reduce the guidance error has become an important issue for the robot arm. [0003] Please refer to figure 1 , is a schematic diagram of the correction robot arm 10 in the prior...
