   Design of Automatic Detection System for Profile of Stamping Plate Based on Vision

Abstract：This paper aims to use the visual sensing technology, through the design of automatic detection system for stamping plate profile for intelligent detection. This paper is pided into seven parts. Starting from the introduction, a total of the introduction, the basic content of the subject, the system structure design, optical system design and selection, summary, thanks and reference to the seven parts. From the introduction began to focus on the visual system design research. Independent drawing drawings, combined with the paper to be able to reflect the full details of the full. In the abstract, briefly mention the various operations required in the following sections. Stamping plate is a processing technology. This process, that is, the use of stamping sheet material to form the final plate. For the dimensional accuracy requirements, material properties and processing of specific conditions of the stamping die requirements, but for the stamping of the parts after the size of the shape accuracy is to meet the requirements. Therefore, the control of the shape and size accuracy of the punching plate needs to be more accurate, and it is necessary to automatically detect the contour size formed after the punching. In this paper, the automatic detection system of non-contact stamping plate is developed by using the method of contour detection of punching plate based on machine vision.The existing tools of the laboratory are used to verify the operation of the automatic detection system of the stamping plate, and the feasibility of the experiment is analyzed. Through the simulation analysis experiment, fully verify the accuracy of the detection system, measuring plate size and batch testing also verify the accuracy of the system and the degree of repeatability.
