specific Embodiment

[0016] Specific embodiment: This online monitoring device for measuring the thickness of smooth panels includes a laser sensor 2 and a signal processing device. The sensors 2 exist in pairs, and the data are transmitted to the signal processing device through cables, and the signal processing device calculates The thickness of the plate 8 to be tested is obtained; the sensors 2 are installed in pairs at corresponding positions at both ends of a "U"-shaped bracket 1, and the "U"-shaped bracket 1 can move according to certain rules through control; the plate to be tested 8 is located on the "U"-shaped bracket 1 In the middle of the groove, crossing motion is performed perpendicular to the plane where the "U"-shaped support 1 is located; a temperature compensation block 3 is installed on the extension surface of the plate 8 to be tested to the "U"-shaped support 1.

[0017] The above-mentioned "U"-shaped bracket 1 is controlled by a moving mechanism, and the moving mechanism inclu...

Abstract

This invention relates to smooth surface board materials thickness on-line measurement and especially to the ones influenced by temperature, which comprises the following steps: eliminating the impact on the structure deformation from temperature through extra set mark block in each journey. The measured board thickness signals from laser sensor, temperature compensation thickness signals and rack journey position signals are sent to the working control machine to accomplish the signal process to realize the monitoring.

Description

technical field [0001] The invention relates to the on-line measurement of the thickness of various boards with smooth surfaces during movement, especially the construction of an online accurate measurement and monitoring system for measuring the thickness of smooth boards that are affected by ambient temperature, have jumps, and whose surface cannot be compressed . Background technique [0002] The current thickness measurement can be simply divided into static measurement and dynamic measurement. Static measurement accuracy is high, and there are many related measuring instruments at home and abroad. Such instruments are generally used in offline mode, and there are many restrictions on use, such as the thickness of the measured body, the measured body must be the same metal substrate, and the The measuring body is in a non-moving state, etc. It is generally used to measure non-ferromagnetic coatings and coatings on ferromagnetic metal substrates, ...
