Optical Corrugation Depth Measurement for Sealing Quality

The patent replaces indirect mechanical measurement methods (sealing force sensors, melting degree measurements) with direct optical measurement. A camera system captures images of corrugation impressions on the sealed film, and image processing algorithms directly measure the immersion depth of corrugations. This substitution provides 100% guarantee of sealing tightness through direct visual evidence of proper corrugation penetration, eliminating the uncertainty of indirect mechanical measurements.

The patent creates an optical copy (image) of the corrugation impression on the sealed film surface. Instead of physically measuring the impression, the system captures a visual copy using a camera and processes this image data to determine immersion depth. This copying approach allows non-contact, high-resolution measurement of the sealing quality without interfering with the sealing process itself.

The patent uses a camera to create an optical copy (image) of the corrugation impression on the film surface. This image copy is then processed using image analysis algorithms to extract the immersion depth measurement. This approach achieves high measurement precision by capturing detailed visual information of the corrugation geometry without requiring complex physical measurement devices.

The patent replaces complex mechanical measurement systems with optical detection. Instead of using physical probes or sensors to measure corrugation depth, the system uses a camera to capture images and computational algorithms to calculate immersion depth from the image data. This substitution simplifies the measurement system while achieving precise direct measurement of sealing quality.

The patent implements continuous quality control by capturing images of the sealed film during its normal transport through the sealing station. The optical measurement system operates continuously without interrupting the sealing process or film feed. The camera captures images at appropriate positions, and image processing occurs in real-time, maintaining seamless production flow while ensuring every seal is measured for quality.

The patent replaces mechanical stopping or slowing mechanisms with optical detection. Instead of halting the sealing process to perform measurements, the system uses a camera to capture images of moving film and processes these images computationally. This allows real-time measurement precision to be achieved while maintaining continuous sealing process operation at full speed.

The patent uses a camera to create optical copies (images) of corrugation impressions on the moving film. These image copies are then processed using image analysis algorithms that can extract measurement data regardless of the film's feed speed. The copying approach allows the measurement system to adapt to various production speeds without requiring mechanical synchronization with the film transport.

The patent implements a dynamic measurement system where the camera and image processing adapt to varying film feed speeds. The system can capture images at appropriate intervals and process them in real-time, adjusting to the production rhythm. This dynamic capability allows non-contact measurement to be maintained across a range of operating speeds without compromising measurement completeness.
