Online detection device for edge sizes of small rectangular plate

Abstract

The invention which belongs to the technical field of product size detection devices concretely relates to an online detection device for edge sizes of a small rectangular plate. Main points of a technology of the invention are characterized in that: a laser range finding principle is adopted, an upper chain plate conveyer is perpendicular to a lower chain plate conveyer; a reclaimer is arranged on the input end of the upper chain plate conveyer, the upper chain plate conveyer and the lower chain plate conveyer are respectively provided with more than one damping pinch roller apparatuses and a pair of laser sensors to respectively detect the length and the width of the small rectangular plate; and discharge ends of the upper chain plate conveyer and the lower chain plate conveyer are respectively provided with a sorting mechanism, and the sorting mechanisms respectively sort products with qualified sizes and products with unqualified sizes, wherein the products with qualified sizes and the products with unqualified sizes are detected by the laser sensors. The device of the invention has the advantages of simple structure, convenient operation, accurate test result, high efficiency, and realization of automatic online detection of the edge sizes of the small rectangular plate and automatic online sorting of small rectangular plates of different edge sizes.

Description

technical field [0001] The invention belongs to the technical field of product size detection devices, and in particular relates to an online detection device for the edge size of a rectangular small plate. Background technique Rectangular small plate products are generally processed on the specification plate through cutting, punching, cutting and other methods according to the design size. Due to processing equipment, processing tools, clamping methods and other reasons, the edge of the produced rectangular small plate will appear dimension There are problems such as excessive precision error and non-parallel opposite sides, so it needs to be inspected to eliminate unqualified products. The general detection methods are divided into manual caliper measurement, linear array CCD or area array CCD measurement. Among them, the accuracy, stability and detection efficiency of manual measurement are relatively low; although linear array CCD or area array CCD measurement can ...

AI Technical Summary

Problems solved by technology

Among them, the accuracy, stability and detection efficiency of manual measurement are relatively low; although linear array CCD or area array CCD measurement can meet the measurement accuracy requirements, it needs light scanning, imaging and image processing, complex equipment, high detection environment requirements, The detection efficiency is low, and it is difficult to meet the online detection requirements of mass production
