A control system and method for on-line magnetic tile detection equipment

Abstract

The invention discloses a control system and method for an on-line magnetic tile detection device. In the control system, the PC includes: a first numbering unit: when the first photoelectric sensor senses the magnetic tile, it is cyclically numbered; an analysis unit: according to the 3D profiler The magnetic tile information obtains the judgment result; the first sending unit: sends the magnetic tile number and the judgment result to the PLC; the first receiving unit: receives the magnetic tile number sent by the PLC; the PLC includes: the second numbering unit: sensed by the first photoelectric sensor When the magnetic tile is numbered; the second sending unit: send the magnetic tile number of the second numbering unit to the PC; the second receiving unit: receive the magnetic tile number and the judgment result sent by the PC; output unit: when the second photoelectric sensor senses The magnetic tiles control the action of the sorting device according to the received magnetic tile number and the judgment result. The invention performs timing control on the magnetic tile online detection equipment, diagnoses and corrects the abnormal operation of the equipment, reduces configuration requirements, and accurately sorts qualified products and unqualified products.

Description

technical field [0001] The invention particularly relates to a control system and method for a magnetic tile online detection device. Background technique [0002] At present, domestic magnetic tile detection basically adopts manual detection method, which has slow detection speed, low detection accuracy, high labor intensity, high false detection rate, takes up a lot of human resources and cannot guarantee uniform quality standards. Therefore, some domestic testing companies have emerged to develop equipment for online testing of magnetic tiles, but basically all companies use PC and PLC-based machine vision methods for online testing of magnetic tiles. Machine vision inspection software is installed on the PC side of this type of inspection equipment, which is responsible for analyzing the two-dimensional images captured by the camera to determine whether they are defective products, and the PLC controls the sorting mechanism to sort qualified products from unqualified pro...

AI Technical Summary

Problems solved by technology

This method has the following technical problems: 1. In order to ensure that the detection and sorting of magnetic tiles must be synchronized one-to-one, one piece is detected, one piece is sorted, and the magnetic tile detection instrument ( There can only be one magnetic tile between the 3D profiler) and the sorting device, and the requirements for the mechanical feeding queue are relatively strict, and because the required magnetic tile spacing is relatively large, the detection efficiency of the magnetic tile cannot be guaranteed

3. The computer PC end sends the detection result signal delay problem

4. Due to the flipping problem, the second-station magnetic tile deviates from the track and does not completely enter the scanning area of ​​the 3D profiler, resulting in the loss of the magnetic tile captured by the PC.

5. Due to a problem with the overturning mechanism, there is a problem of tile blockage at station 1 and station 2

The emergence of the above problems will bring very serious consequences to the magnetic tile online testing equipment, and in the normal production process, it will bring serious hidden dangers to product quality
