Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic detection, in particular to a steel plate automatic detection device and method thereof. BACKGROUND

[0002] At present, the steel plate detection is mainly completed by manual method. The length and width of the steel plate are measured by a meter ruler, and the thickness of the steel plate is measured by a micrometer. The measurement results are recorded on the surface of the steel plate and then input into a computer. The measurement accuracy depends on the experience and responsibility of the detection workers, and the measurement error is random. In addition, due to the influence of rolling, shearing and other factors, the steel plate is generally not a standard rectangle. The workers can only detect the length, width and thickness of the fixed position of the steel plate, and cannot find the minimum width, length and thickness required by the national standard. Therefore, the misjudgment may occur. For the steel plate size parameters such as camber, cutting angle and unevenness, which are difficult to measure manually, the qualitative method is generally used for visual determination, and the experience is used to determine whether it is qualified. There is no quantitative value for judgment, which further brings uncertainty to the steel plate detection results. After the steel plate size measurement is completed, the workers manually retrieve the design size of the steel plate from the computer according to the steel plate characteristic code, and manually judge whether it is qualified. The judgment results are marked on the surface of the steel plate. The whole process is time-consuming and affects the production rhythm.

[0003] In the steel plate production process, some customers purchase the steel plate according to the size of the steel plate. Therefore, the size of the steel plate is an important parameter for the production control of the steel plate. In order to meet the requirements of customers, the steel production enterprises usually leave a certain size allowance on the size of the steel plate to ensure that the product does not meet the size requirements of the customers. If the size precision of the steel plate cannot be accurately controlled, the size allowance may be too large, which will provide more weight of the steel plate to the customers, especially for the steel plate with large thickness (thickness of 50-450mm).

[0004] In the traditional steel plate size control method, the length of the steel plate is measured by measuring the rotation of the roller. However, due to the change of material specifications and the fluctuation of production speed and other process problems, it is difficult to effectively control the length precision. In addition, for the cross-cut plate with high shape size requirements, the manual measurement method is generally used. The tape measure is used to measure the length of two diagonal lines of the rectangular steel plate respectively, and then the deviation of the two diagonal line lengths is used to evaluate the rectangular degree of the steel plate. However, due to the low measurement accuracy of the tape measure itself and the large measurement error of manual measurement, the result of the rectangular degree of the steel plate judged by the tape measure also has a large deviation.

[0005] In the prior art, there are automatic measuring devices for measuring the size of a steel plate using an infrared distance measuring method and automatic measuring devices for measuring the size of a steel plate using a mechanical contact measuring method. However, the accuracy of the infrared distance measuring method is low, and thus the high-precision requirement of the size of the steel plate cannot be met. When the mechanical contact measuring method is used, the measuring accuracy is difficult to control due to process problems such as changes in material specifications and fluctuations in production speed.

[0006] A steel plate thickness online real-time automatic detection device disclosed in Chinese Patent CN201889675U is composed of an engineering cylinder, a detection device support, a sensor, and a detection probe. The engineering cylinder is installed on the detection device support. A mechanical spherical probe is installed on the plunger head of the engineering cylinder. The mechanical spherical probe is rigidly connected to a sliding guide rail through a connecting block. The sliding guide rail is vertically and slidably connected to a guide rail seat. The guide rail seat is installed on the detection device support. A photoelectric position detection switch is installed on the lower part of the sliding guide rail. The upper part of the sliding guide rail is rigidly connected to the reading head of a linear position sensor. The linear position sensor is installed on the detection device support. The reading head slides on the linear position sensor along with the sliding guide rail. The mechanical spherical probe starts automatic real-time detection after contacting the steel plate. The steel plate thickness is detected online in real time without stopping the machine, the work efficiency is improved, the labor intensity is reduced, and the safety of the equipment is increased.
