Product surface powder spraying quality monitoring analysis management system based on machine vision

Abstract

The invention discloses a product surface powder spraying quality monitoring analysis management system based on machine vision. Comprising a product surface coating appearance defect identification module, a product surface coating detection area division module, a spraying database, a coating detection area basic parameter acquisition module, a coating performance parameter acquisition module, a quality modeling analysis module, a supervision cloud center and a display terminal. Appearance defect detection, basic parameter detection and performance parameter detection are respectively carried out on a surface coating film of a powder spraying product, so that a spraying appearance quality coefficient, a spraying basic parameter quality coefficient and a spraying performance parameter quality coefficient corresponding to the surface coating film of the powder spraying product are obtained; therefore, whether the spraying quality of the powder spraying product is qualified or not is judged comprehensively, comprehensive quality detection of surface spraying of the powder spraying product is achieved, the defect that surface spraying quality monitoring of the powder spraying product is too one-sided at present is overcome, and the reliability of a detection result is improved.

Description

technical field [0001] The invention belongs to the technical field of powder spraying quality monitoring, in particular to a machine vision-based product surface powder spraying quality monitoring analysis management system. Background technique [0002] In recent years, due to the improvement of the quality of household electrical appliances such as cleaning appliances, refrigerators, and microwave ovens, powder coatings have entered the housing market of household electrical appliances due to their bright colors, durability, impact resistance, and corrosion resistance. be more widely applied. Since powder spraying is operated by spraying equipment under certain environmental conditions, the control accuracy of spraying equipment and the suitability of the spraying environment will affect the quality of powder spraying, and the quality of powder spraying is directly reflected in the appearance of spraying , so it is very necessary to monitor the quality of powder spraying...

AI Technical Summary

Problems solved by technology

This method of detection and judgment ignores the detection of basic parameters such as hardness and thickness of the coating film and the detection of performance parameters such as adhesion and impact resistance of the coating film. These basic parameters and performance parameters also have an impact on the quality of spraying. When When the hardness, thickness, adhesion, and impact resistance of the coating film do not meet the standard requirements, even if the appearance of the coating film is complete and there are no defects, the powder sprayed product will have quality hazards in the actual use process, which will affect the normal operation of the product. use

Therefore, only the detection of appearance defects on the surface coating of powder sprayed products cannot fully reflect the spraying quality of the sprayed products. The basis for qualified judgment is obviously too one-sided, resulting in low reliability of judgment results
