Medium or heavy steel plate morphology detection system based on controllable symmetrical double-line laser angle and method thereof

Abstract

The invention discloses a medium or heavy steel plate morphology detection system based on a controllable symmetrical double-line laser angle, and a method thereof. A sensor cabinet is internally provided with two planar array CMOS cameras in an equal-height plane. Each planar array CMOS camera is provided with a camera lens and furthermore is fixed on a bracket through a mounting device. Two sides of the planar array CMOS camera are respectively provided with a linear laser source. A pulse speed testing velocimeter is fixed at the side of a conveyor belt. The to-be-measured medium or heavy steel plate is placed on the conveyor belt. The to-be-measured medium or heavy steel plate is provided with the laser ray overlapping area of the symmetrical linear laser sources. Correlation is formed between a photoelectric switch transmitter and a photoelectric switch receiver. The sensor cabinet is placed on a bracket. A detecting device is controlled by a control device. According to the medium or heavy steel plate morphology detection system, simple calibration method is realized in detecting by two symmetrical linear laser sources, and furthermore high detection resolution and high precision are realized. The detecting system with two symmetrical linear laser sources is adopted, thereby realizing large incident angle of the linear laser, preventing detection inflection point failure, reducing drift and ensuring accurate and reliable result.

Description

technical field [0001] The patent of the present invention relates to a shape detection system and its method, in particular to a medium-thick plate shape detection system and its method based on symmetrical two-line laser angle controllable. Background technique [0002] As my country's processing industry gradually adopts automated production lines, the manufacturing industry with cold-rolled medium-thick steel plates as the main raw material has higher and higher requirements for its shape. Flatness control has become an urgent problem to be solved in the metallurgical industry today, and flatness detection is one of the important prerequisites for automatic flatness control. Especially with the rapid development of such components in the direction of large-scale production, extreme use environment, large-scale and high-speed related equipment, the shape detection technology of medium-thick steel plates has become more important and urgent, and it will be used in reliable...

Problems solved by technology

[0003] Due to the great uncertainty in the contour shape of the head and tail of the rolled plate, the traditional detection principle cannot accurately obtain the contour information of this part, or even detect it.

Furthermore, the existing profile detector based on CMOS image sensor cannot complete the detection of the strip profile independently, because it cannot measure the height information of the surface phase of the strip, but relies on the upper level system or other height detection equipment , which severely limits the application range of the profile detector
