A kind of measuring system and measuring method

Abstract

A measurement system and a measurement method, the measurement system includes: a measurement module, including a camera and a laser displacement sensor; the laser displacement sensor is used to measure from its measurement reference point along its laser emission direction to a The distance between the measurement points; the calculation device is used to calculate the angle of rotation around the x-axis and the rotation angle around the y-axis in order to make the first assembly surface and the second assembly surface overlap the second component. The rotation angle and the amount of translation along the z-axis direction; the camera is used to take pictures of the feature groups of the feature group; the computing device is also used to calculate the first The two components need to be translated along the x-axis direction, the translation amount along the y-axis direction, and the rotation angle that needs to be rotated around the z-axis to move the feature group to a preset position after the midpoint coincides with the reference point. The measurement system has high measurement accuracy.

Description

technical field [0001] This article relates to robotics, in particular to a measuring system and measuring method. Background technique [0002] At present, the final assembly of high-precision equipment with large load and large size is completed manually. The traditional manual-based assembly mode has problems such as backward assembly equipment, poor accuracy consistency, and uncontrollable risks. This assembly mode is only suitable for single-piece, small-batch, small-scale, and simple-structure spacecraft assembly, but it is far from meeting the requirements of modern large-scale High-precision equipment requires high precision, high efficiency, and flexibility for final assembly. Robot autonomous assembly provides an effective solution for improving the assembly accuracy, efficiency and flexibility of high-precision equipment, which can greatly improve the comprehensive quality of equipment and the production level of manufacturing enterprises. With the rapid develop...

Problems solved by technology

However, the current robot autonomous assembly system usually adopts three construction methods: building in the end coordinate system, building in the installation base coordinate system and building in the global coordinate system. These three coordinate system construction methods will have deformations that affect accuracy, The narrow space leads to problems such as incomplete collection of information and the inability to use the diverse needs of assembly tasks
