ManualGluing Inspection Powered by AI Vision and Machine Vision

Ascar manufacturing technology and processes continue to improve, automobile gluingtechnology has become widely adopted by major automakers and componentmanufacturers. Automobile gluing serves multiple purposes, such as bondingsimilar or dissimilar materials on the vehicle body, optimizing productstructures, and even replacing some welding or riveting processes to enhancethe aesthetics of the vehicle while optimizing and simplifying productionprocesses. The quality of glue application directly affects the product qualityand driving safety of the vehicle. Therefore, gluing inspection is an essentialstep in the intelligent and automated production workshop of car manufacturers.

LanyouTechnology, combining AI vision with machine vision, proposes an intelligentgluing inspection solution. This solution utilizes AI algorithms to activelyintervene in quality control, achieving real-time inspection during production,convenient quality inspection, and efficient problem traceability. To accountfor variations in environmental lighting and materials in actual productionsettings, an adaptive AI algorithm is employed to dynamically adjust andoptimize imaging, addressing issues of inaccurate detection under variousinterference conditions and significantly improving the accuracy and efficiencyof product inspection.

1. Capture glue applicationphotos: Utilize high-precision cameras and lighting to capture the glueapplication process on the industrial production line and extract valuableimage data.

2. Analyze algorithm models:Compare different algorithms in terms of precision, speed, and stability whenprocessing glue application photos, and select the most suitable model forpractical application requirements.

3. Generate reports fortraceability: Prepare reports on statistical data, imagecomparisons, and process monitoring, to help managers better understand thequality and efficiency of the glue application process and promptly identifyand resolve issues.

4. Provide alerts forabnormal glue application: Timely identify anomalies such as uneven applicationand interruptions through real-time monitoring of the gluing process, and issuealerts to facilitate prompt action by staff.

EffectiveResults

Eliminationof the outflow of defective products: Machine vision enables completequality inspections, allowing for timely remedies of quality defects andpreventing the outflow of defective products.
