Description

Technical Field

[0001] The utility model relates to the technical field of balloon production, in particular to a balloon appearance defect detection device. Background Art

[0002] Balloon molding is done through a process called stretch blow molding, where the polymer tube is stretched in both axial and radial directions under pressure and high temperature. Common quality problems in balloon production include gel spots, fish eyes, impurities, drag marks, zipper lines, bends, and visual defects. These problems may lead to defects such as rupture, fatigue, or incorrect dimensions. Such defects may endanger patient safety, so surface defects need to be detected during balloon production.

[0003] Existing methods for defect detection of balloon appearance generally use manual methods and visual inspection methods. Manual inspection is to use the staff's visual inspection to check the surface defects of the balloon, but this method is greatly affected by human factors and is prone to errors. The visual inspection method uses a non-contact optical inspection system to photograph the surface of the balloon, start the required brightness of the optical lighting, start the camera to capture the entire periphery of the balloon product, and use AI recognition technology to analyze the image to give a detection conclusion.

[0004] However, during actual use of the above-mentioned equipment, the ends of the balloon need to be clamped and stretched to prevent excessive wrinkles on the surface of the balloon. However, since the balloon itself generally has a certain elasticity, it may slip between the upper and lower clamps when stretched, which results in the need to adjust the balloon multiple times during the inspection process. Moreover, as the tensile strength of the balloon increases, the balloon is more likely to fall off, affecting the overall inspection efficiency of the device. In view of this, we propose a balloon appearance defect detection device. Utility Model Content
