Control system and method of online detection device for magnetic shoes

Abstract

The invention discloses a control system and method of an online detection device for magnetic shoes. A PC in the control system comprises a first numbering unit used for cyclic numbering when a firstphotoelectric sensor senses the magnetic shoes, an analysis unit used for acquiring a judgment result according to magnetic shoe information acquired by a 3D contourgraph, a first sending unit used for sending serial numbers of the magnetic shoes and the judgment result to a PLC, and a first receiving unit used for receiving the serial numbers, sent from the PLC, of the magnetic shoes; and the PLC comprises a second numbering unit used for numbering when the first photoelectric sensor senses the magnetic shoes, a second sending unit used for sending serial numbers, numbered by the second numbering unit, of the magnetic shoes to the PC, a second receiving unit used for receiving the serial numbers of the magnetic shoes and the judgment result sent from the PC, and an output unit used for controlling a sorting device to work according to the received serial numbers of the magnetic shoes and the judgment result when a second photoelectric sensor senses the magnetic shoes. According to the control system and method, sequential control is conducted on the online detection device for the magnetic shoes, equipment which operates abnormally is diagnosed and corrected, configuration requirements are lowered, and qualified products and unqualified products are accurately sorted.

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
