In this case, the bottle cap deformation assessment value P2 is determined: P2=R; where R is a preset value, which is specifically set by professional staff. In this case, the bottle cap deformation is most obvious, and the obtained bottle cap deformation assessment value P2 is sufficient to cause the capping result to be unqualified in the subsequent result judgment; If there is contact intersection, perform the following steps to determine the cap deformation evaluation value: BS21: Get the intersection line between the second calibration surface and one end of the bottle cap: Identify whether the intersection line is a closed figure: If it is not a closed figure, in this embodiment, it is an arc segment: obtain and measure the length of the intersection line, recorded as L1, and at the same time obtain the circular circumference Ls of the bottle cap, and determine the bottle cap deformation evaluation value P2 by the following formula: ; It should be noted that the bottle caps of oral solutions of the same standard are uniformly designed, so the circular circumference and radius of the bottle cap are preset fixed values, which can be measured in advance; If it is a closed figure, in this embodiment, it is a circular or arc-shaped figure: identify the integrity of the closed figure, and determine the bottle cap deformation evaluation value according to the integrity of the closed figure: The specific method of identifying the integrity of the graphic and determining the bottle cap deformation evaluation value according to the integrity of the graphic is as follows: Obtain a circle that intersects with the outer surface of the oral solution bottle on the second calibration surface, record it as the reference circle, and display it on the second calibration surface.

Combining the three evaluation results, the overall screw cap packaging evaluation value ZP is determined by the following weighted formula: in, , is the weight coefficient, which is determined by professional staff based on experience; After the capping process is completed, this step conducts multi-dimensional and detailed inspections on the flatness, deformation, and overall height of the bottle cap, and uses methods such as vertical line segment inspection, calibration surface establishment, and graphic integrity recognition for quantitative analysis. After integrating various test data, the overall packaging evaluation value is determined through weighted calculation, which can not only comprehensively and objectively reflect the actual effect of the capping process, but also promptly discover and locate potential abnormal problems, ensuring that product quality meets strict standard requirements, thereby improving the inspection accuracy and stability of the entire production process; Step 3: Classify the screw cap packaging inspection according to the overall screw cap packaging evaluation value, and divide it into screw cap packaging standard qualified class, screw cap packaging basically qualified class and screw cap packaging basically qualified class; and take corresponding follow-up inspection measures based on the classification results; The screw cap packaging inspection classification is carried out according to the overall screw cap packaging evaluation value, and is divided into screw cap packaging standard qualified class, screw cap packaging basically qualified class and screw cap packaging unqualified class; and based on the classification results, the specific method of taking corresponding follow-up inspection measures is as follows: Obtain the overall screw capping packaging evaluation value ZP and make the following judgments on the screw capping packaging detection classification: like , classified as qualified for screw cap packaging standards, directly judged as qualified, and no subsequent manual inspection and processing is required; like , classified as basically qualified for screw-cap packaging, the oral solution bottles with screw-cap packaging are marked with yellow, and manual inspection is required later; like , classified as unqualified screw-cap packaging, the oral solution bottles with screw-cap packaging are marked in red and automatically rejected later; Among them, K1 and K2 are preset values, which are determined by professional staff, and K2>K1; According to the aforementioned comprehensive evaluation value, this step divides the screw-cap packaging results into three categories: standard qualified, basically qualified and unqualified, and quickly distinguishes and processes them by marking the products with different colors (e.g. yellow indicates that manual re-inspection is required, and red indicates automatic rejection). This not only greatly improves the detection efficiency and reduces the burden of manual inspection, but also responds to abnormal products in the first place, effectively preventing unqualified products from entering the market, ensuring the overall quality and safety of the final product, but also provides a clear reference for subsequent process adjustments.

For the fine-tuning force and torque of the automatic capping machine, experienced staff or program design engineers perform fine-tuning of the force and torque preparation plan through pre-program settings before this process; In this step, a curve chart is constructed based on the defect rate data obtained from each inspection. By monitoring the changing trend of the defect rate in real time, it is automatically determined whether it exceeds the preset threshold, and corresponding feedback control measures are triggered accordingly, such as automatic shutdown, fine-tuning of torque and moment, or continuing to maintain normal operation. This not only achieves timely response to abnormal fluctuations in the production process, but also can continuously perform self-adjustment and optimization during equipment operation, thereby greatly reducing the defective product generation rate and improving the automation level and economic benefits of the entire production line.
