Embodiment Construction

[0013] refer to figure 1 . In the embodiment described below, the measurement system for detecting the repetitive positioning accuracy of the manipulator mainly includes a first camera component 1 and a second camera component 2 fixedly placed in an orthogonal direction, a measured object 3 and a computing component 4 . The first camera assembly 1 and the second camera assembly 2 are equipped with sensors, and when the measured object 3 enters the field of view of the first camera assembly 1 and the second camera assembly 2 and the position is stable, the calculation assembly is automatically triggered to execute the calculation program. The measured object 3 is connected to the end of the manipulator, and can move with the manipulator so that the measured object 3 is placed within the common field of view of the first camera assembly 1 and the second camera assembly 2 . The measured object 3 has a mounting hole that can be installed at the end of the manipulator, and there a...

Abstract

The invention provides a measuring system for detecting repeated positioning accuracy of manipulators and aims to provide a measuring system high in measuring accuracy, simple in equipment, unlimited by environmental space and convenient to operate. The technical scheme for implementation of the measuring system includes that a detected object (3) is connected to the tail end of a manipulator, and the manipulator moves to enable the detected object (3) to be placed within a common field range of a first camera component (1) and a second camera component (2); sensors arranged on two groups of cameras are connected to a computation module (4) for communication through data transmission cables to form the measuring system for detecting repeated positioning accuracy of the manipulators, the computation module (4) receives manual trigger signals to capture images acquired by the first camera component (1) and the second camera component (2) at different moments and records and computes position infinitesimal displacement of the captured images of the detected object (3) at each moment through an internal resolving program, and repeated positioning accuracy of the manipulator can be worked out by measurement for multiple times.

Description

technical field [0001] The invention relates to a measurement system for all detection of repeat positioning accuracy of manipulators. Background technique [0002] With the development of science and technology, the requirements for the position accuracy of industrial robots are getting higher and higher. This requires a corresponding high-precision, high-automation, stable and reliable test system to adapt to it, in order to make an objective evaluation of it. Among them, positioning accuracy and repeat positioning accuracy are very important accuracy indicators for whether the manipulator can accurately clamp and transfer the workpiece. Position repeatability is a statistic about precision. For any industrial manipulator, even under the same environment, the same conditions, the same action, and the same command, the position of each action cannot be completely consistent, and there will be certain errors. When testing the position repeatability of an industrial manipu...
