Manual Gluing Inspection Powered by AI Vision and Machine Vision

As car manufacturing technology and processes continue to improve, automobile gluing technology has become widely adopted by major automakers and component manufacturers. Automobile gluing serves multiple purposes, such as bonding similar or dissimilar materials on the vehicle body, optimizing product structures, and even replacing some welding or riveting processes to enhance the aesthetics of the vehicle while optimizing and simplifying production processes. The quality of glue application directly affects the product quality and driving safety of the vehicle. Therefore, gluing inspection is an essential step in the intelligent and automated production workshop of car manufacturers.

Lan-you Technology, combining AI vision with machine vision, proposes an intelligent gluing inspection solution. This solution utilizes AI algorithms to actively intervene in quality control, achieving real-time inspection during production, convenient quality inspection, and efficient problem traceability. To account for variations in environmental lighting and materials in actual production settings, an adaptive AI algorithm is employed to dynamically adjust and optimize imaging, addressing issues of inaccurate detection under various interference conditions and significantly improving the accuracy and efficiency of product inspection.

1. Capture glue application photos: Utilize high-precision cameras and lighting to capture the glue application process on the industrial production line and extract valuable image data.

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

3. Generate reports for traceability: Prepare reports on statistical data, image comparisons, and process monitoring, to help managers better understand the quality and efficiency of the glue application process and promptly identify and resolve issues.

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

Effective Results

Elimination of the outflow of defective products: Machine vision enables complete quality inspections, allowing for timely remedies of quality defects and preventing the outflow of defective products.

Problem traceability in 1 minute: Historical glue application photos can be retrieved based on any defective product’s identification number, enabling quick confirmation of any gluing quality issues.
