Problems solved by technology
[0004] In actual production, the on-line detection of the strip is carried out in the moving state of the conveying roller table, so the strip will have problems such as inclination and fluctuation, while the position of the detection element in the traditional strip detection device is fixed, and the strip The inclination and fluctuations in the movement can easily cause the strip to deviate from the optimal detection range of the detection element, which has a great impact on the accuracy of the shape detection. Therefore, the existing static shape detection technology can no longer meet the requirements for the detection accuracy of the shape. Require

The invention discloses a non-contact flatness detection device capable of adjusting the measurement breadth. The device comprises a frame guide rail and a frame, wherein a breadth adjustment guide rail is arranged on the frame, a first breadth adjustment plate and a second breadth adjustment plate are connected to the breadth adjustment guide rail in a sliding manner, a first eddy current sensoris installed on the first breadth adjustment plate, a second eddy current sensor is installed on the second breadth adjustment plate, a third eddy current sensor is installed on the breadth adjustmentguide rail, and the first eddy current sensor, the second eddy current sensor and the third eddy current sensor are all connected to a controller. The flatness of a plate or strip is detected by thefirst eddy current sensor, the second eddy current sensor and the third eddy current sensor, so that the plate or strip is not damaged; the measurement breadth is adjusted by changing the positions ofthe first breadth adjustment plate and the second breadth adjustment plate; and the position of the frame is changed to follow the displacement of the first breadth adjustment plate, the second breadth adjustment plate and the plate or strip, so that the plate or strip is always within the measurement breadth range.
Description
technical field [0001] The invention belongs to the technical field of automatic testing, and in particular relates to a non-contact plate shape detection device which can automatically adjust and measure width. Background technique [0002] With the continuous improvement of the user's requirements for the quality of the plate, the shape measurement and control system is becoming more and more important. The shape is an important index to measure the flatness of the strip. During the manufacturing process, the shape of the strip is dynamically detected online by the shape detection device. Due to the complex and diverse structure of the strip cold rolling mill, the shape detection results can directly reflect the quality of the strip. According to the shape detection The results and precision require that the rolling mill be adjusted, which greatly improves the product quality and automatic production of the strip. Therefore, the flatness detection device plays an irreplace...
