A method for controlling flatness of plate forming

Abstract

The embodiment of the present invention discloses a method for controlling the flatness of plate forming, which includes the following steps: step 100, adjusting the radar wave emission direction and angle, so that the radar wave covers the entire production line; step 200, passing the time difference of radar wave propagation Calculate the vertical height from the surface of the gypsum board to the emission position, and transmit the calculation result to the recognition center; step 300, set a threshold at the recognition center, compare the calculation result with the threshold to form a compensation discrete value, and divide the compensation discrete value according to the same continuous color The changing scale is marked on the image of the gypsum board; step 400, according to the result of color identification recognition, the gypsum board that exceeds the threshold is automatically discarded; the present invention can fully cover and detect the flatness of both sides of the gypsum board surface based on continuous radar waves, through The internal computing imaging is conducive to improving the detection accuracy. It can also be marked by color so that the quality inspector can quickly evaluate the production quality of the gypsum board through the generated image, and it is also convenient for automatic waste.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of process detection, and in particular to a method for controlling flatness of plate forming. Background technique [0002] In the existing gypsum board production process, the production of gypsum boards is generally realized through automatic feeding and leveling processes. In the production process, in order to ensure the quality of the product, it is necessary to detect the flatness of the surface of the gypsum boards. [0003] In the prior art, the detection of the flatness of gypsum is generally detected by human eye recognition, so it is necessary to designate corresponding posts for quality control during high-precision production. However, it is well known that manual monitoring is difficult to grasp the reliability and balance of monitoring quality, because human eye recognition is accidental and fatigued, and long-term detection will inevitably lead to errors, and manual...

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides a method for controlling the flatness of plate forming. The detection method of radar waves is used to solve the problem that the quality control of human eye detection in the prior art is not strict, and the flatness parameters cannot be completely recorded, which is not conducive to follow-up. The problem of process optimization
