Industrial automatic three-dimensional detection system and method

Abstract

The invention provides an automatic three-dimensional detection system and method. The system comprises a workpiece conveying system, a working platform, one or more three-dimensional optical scanningdevices, a data transfer station and a computer terminal. The system has the advantages that the system is applied to the industrial automatic shape detection of a plurality of production-line objects and the automatic shape scanning and detection of a non-production-line single object, a detection mode using a robot to grab a workpiece and place the workpiece on the scanning working platform ora stop and detection working mode, which does not need robot grabbing, on a production-line conveying belt is adopted, a coordinated detection mode using one or more three-dimensional optical scanningdevices arranged on the periphery of a production line is used to lower the use difficulty, maintenance cost and manpower cost of three-dimensional scanners, and detection efficiency is greatly improved.

Description

【Technical field】 [0001] The invention relates to the field of manufacturing and processing of products and parts, in particular to an industrial automation three-dimensional detection system and method. 【Background technique】 [0002] Non-contact three-dimensional scanning measurement technology has entered our lives more and more, and is widely used in all aspects of product reverse development design and testing. The optical three-dimensional scanning system is a precision measurement scientific instrument used to detect and analyze, Simulate the geometric structure and appearance data of objects or environments in the real world. The collected data are often used for 3D reconstruction calculations, comparative analysis of objects with obvious characteristics, and creation of digital models of actual objects in the virtual world. These models have a wide range of uses, and are important in the fields of 3D teaching, industrial design, reverse engineering, robot guidance, ...

AI Technical Summary

Problems solved by technology

[0003] In the past, due to limited technology, the application of three-dimensional inspection technology on the production line progressed slowly. Artificial naked eye inspection and fixture inspection became the main inspection methods at that time. With the development of science and technology, and the improvement of people's living standards, automobiles and other The demand for products continues to increase, the speed of the intelligent production line is accelerated, and the limitations of manual inspection by tooling and fixtures are highlighted, which can no longer meet the requirements of batch inspection of the production line
