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

Embodiment Construction

[0039] The embodiments of the present invention are described below by specific specific embodiments. Those who are familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the present invention. , not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] The invention provides a method for controlling the flatness of sheet metal forming, which mainly includes the following three aspects:

[0041] First, the flatness of the gypsum board is detected by radar waves;

[0042] Second, the test results are fed back to the waste discharge platform, and the unqualified products are determined according to the preset size standard of the gypsum board through the ...

Abstract

The embodiment of the invention discloses a plate forming flatness control method. The method comprises the following steps that S100, the radar wave emission direction and angle are adjusted, and theradar wave can cover a whole production line; S200, the vertical height of the gypsum board surface to the emission position is calculated by the time difference of the radar wave propagation, and the calculation result is transmitted to a recognition center; S300, a threshold is set at the recognition center, the calculation result is compared with the threshold value to form a compensation discrete value, and the compensation discrete value is identified on the gypsum board image according to a proportional scale with the same continuous color change; and S400, the waste gypsum board exceeding the threshold value is automatically discharged according to the result of the color identification. According to the method, the flatness of the two sides of the gypsum board surface can be detected through full coverage based on continuous radar wave, the detection precision can be improved by internal computing imaging, the production quality of the gypsum board can be quickly evaluated byquality inspection personnel through the generated image through color identification, and meanwhile, automatic waste discharging is facilitated.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of process detection, in particular to a method for controlling the flatness of sheet metal forming. Background technique [0002] In the existing gypsum board production process, the production of gypsum board is generally realized by automatic discharging and leveling process. In order to ensure the quality of the product in the production process, it is necessary to test the flatness of the surface of the gypsum board. [0003] In the prior art, the detection of gypsum flatness is generally detected by human eye recognition, so in high-precision production, a corresponding post needs to be set up for quality control. However, it is well known that manual monitoring is difficult to grasp the reliability and balance of monitoring quality, because human eye recognition is contingent and fatigued, and long-term detection will inevitably produce errors, and manual recognition is only refl...
