Abstract
Description
Technical Field
[0001] The present invention relates to a method and system for quality monitoring of a thermochromic film production line. Background Art
[0002] Thermosensitive color-changing materials (referred to as temperature-changing materials for short) are a special type of functional materials that repeatedly change color with the rise or fall of temperature. Thermochromic coatings and films belong to temperature-changing materials, also known as thermochromic inks or thermochromic paints, which are prepared by mixing thermosensitive color-changing pigments. Thermosensitive color-changing pigments are prepared from an electron transfer type organic compound system. Electron transfer type organic compounds are a class of organic chromogenic systems with special chemical structures. At a specific temperature, due to electron transfer, the molecular structure of the organic compound changes, thereby realizing color transformation.
[0003] During the production process of thermochromic films, it is very crucial to determine the accuracy and stability of production control parameters. However, manual parameter adjustment is often affected by subjective experience, making parameter optimization complex, time-consuming, and resource-consuming. This method relying on manual subjective judgment limits the comprehensive consideration of long-term stability, and due to the limited accuracy of parameter adjustment, multiple adjustments may be required, further reducing production efficiency.
[0004] To sum up, at the present stage, there are defects that the determination of production control parameters for thermochromic films needs to be based on a large number of trial productions by staff and multiple adjustments and modifications. Restricted by the subjectivity of manual parameter adjustment, the determination of production control parameters consumes a large amount of time and resources while indirectly reducing the production efficiency of thermochromic films.
