Problems solved by technology

At present, the general shape measurement of the strip is contact-type, and the measurement of the strip with high requirements such as surface cleanliness cannot be satisfied, and the maintenance is difficult. Moreover, if the shape of the strip is measured under different working conditions, other Complicated calculations can easily lead to low accuracy

Abstract

The invention discloses a non-contact flatness measurement model solving device with simple and diversified measurement ways. The non-contact flatness measurement model solving device comprises a rectangular operating platform, wherein a supporting seat is arranged below the operating platform, and side plates are fixedly arranged on the two sides of the operating platform; a pneumatic vibration-guiding suction disc and a displacement sensor are arranged on the operating platform, the pneumatic vibration-guiding suction disc is connected with a pneumatic distributor and a control device, and the pneumatic distributor is connected with a gas pressure inlet through a high-frequency valve. Through the vibration guiding of the pneumatic vibration-guiding suction disc on strips, the displacement sensor outputs strip vibration data, the data is processed through software, and a conclusion is drawn. The device can be applied to online flatness measurement and can also be used for fault diagnosis of flatness measurement. The operation of the device is non-contact, so that requirements of the static measurement model description of the strips, which has the characteristics of being high in surface cleanliness and the like, are met.

Description

technical field [0001] The invention belongs to a flatness measuring device, in particular to a non-contact flatness measuring device. Background technique [0002] Intuitively, the plate shape refers to the warpage of the plate and strip, and its essence is the distribution of residual stress inside the strip. As long as there is residual stress inside the strip, it is poor shape. When measuring strip shape, the processing of measurement data usually requires a measurement model to accurately calculate the shape of the measured object. The measurement model is mainly used to describe the material type, material specification, external tension, suspended strip length, Multivariate mapping between external stimuli and actual flat shape. At present, the general shape measurement of the strip is contact-type, and the measurement of the strip with high requirements such as surface cleanliness cannot be satisfied, and the maintenance is relatively difficult. Moreover, if the sh...
