Abstract
Disclosed are a device and a method for detecting strip steel end face shape on line. Image acquisition devices are respectively arranged on strip steel end faces on two sides of an advancing direction of strip steel and disposed on a motor screw guide rail which is arranged on a motor support provided with a motor control device; the motor control device controls a cable chain in the motor screw guide rail to drag and drive the image acquisition devices that are connected with the cable chain to slide leftwards and rightwards synchronously along the motor screw guide rail. Strip steel end faces of two sides of the strip steel, entering the image acquisition devices, are illuminated and observed, the strip steel end faces and upper and lower surfaces thereof are imaged, and therefore, the effect of acquiring image information of three surfaces by the aid of a sensor is achieved, the image information is displayed on a subsequent display device to assist in online detection to strip steel end face shape and quality judgment of the strip steel, detection results are visual, clean and accurate, and the detection timeliness is high. The device and the method are applicable to field of online observation and detection to end face shape of various strip steel.
Description
Technical field
The present invention relates to the field that a kind of pattern of the appearance to the object end face is detected, relate in particular to the online device and method detected of observing of a kind of carrying out to the end face pattern with steel, improved the speed and the timeliness that detect with steel, be conducive to elevator belt product made from steel quality.
Background technology
At present, in each family's steel production enterprise, because the quality requirements to belt steel product on market is more and more higher, and be related to one of standard of strip quality-band steel end face pattern, requirement to this with steel end face pattern also becomes originally higher, because with the judgement of steel end face pattern in the subsequent production of belt steel product in very important status, as mishandling while producing, affect strip surface quality when slight, when serious, can cause belt steel surface to tear, broken belt occurs, and causes product directly to be scrapped.
Then lack the inspection of directly effective means with steel end face pattern with steel inspection personnel always.Common way under prior art is after the band steel has been produced at present, form band steel coil of strip, quality inspection personnel is by manual observation steel roll rim situation, observe the neat degree of steel roll rim, simultaneously, for the trimming material, whether normally by means such as magnifieres, observe trim lines, and the band steel end face sideline after trimming judges and is with steel end face pattern with methods such as whether the trim lines distance are stable.
Yet such detection method and the shortcoming of means are quite obvious:
This kind of manual detection mode need to expend a large amount of artificial, and inefficiency;
2. the testing result of this kind of manual detection mode often is limited to operator's subjectivity, easily causes the erroneous judgement of failing to judge;
3. the problem of this kind of manual detection mode maximum is, the ageing serious hysteresis of testing result, and after often waiting and realizing and band steel abnormality occurs, production line has been produced in enormous quantities with the product of similar flaw, to manufacturing enterprise, causes unnecessary loss.
Therefore now the device and method with steel end face pattern in the urgent need to a kind of novel detection, can detect online, and discovery band steel end face pattern that can be promptly and accurately is abnormal, notifies the producer to improve technological parameter, avoids defect in batches to produce.
Summary of the invention
Be difficult to the situation with steel end face pattern is made the judgement of timely preparation in order to solve detection method under prior art, then easily affect the shortcoming of strip quality, the invention provides a kind of for the online device and method detected with steel end face pattern, by needs being carried out to the band steel both sides end face of end face quality testing, mounting strap steel end face signal acquisition device, this device can obtain the band steel image information with steel end face and end face both sides, process and provide the quality condition complete with the steel end face by pattern information processing system, particular content of the present invention is as described below:
