Background and Customer Needs<\/strong><\/h3>\n

In electronics manufacturing, ensuring precise glue dispensing before the PCB enters the soldering machine is crucial for product quality. A customer required an automated inspection system to verify the accuracy of glue application, as defects in dispensing could lead to product failures.<\/p>\n

After the glue is dispensed from the dispensing machine, issues such as incomplete application, leakage, or unintended contact with video memory components may occur, requiring inspection. Previously, the inspection relied on manual monitoring, which was prone to human fatigue, inconsistencies, and a lack of traceable inspection data.<\/p>\n

Challenges<\/strong><\/h3>\n
    \n
  • Manual Inspection Limitations<\/strong>: Operators needed to constantly monitor the process, increasing the risk of fatigue and misjudgment.<\/li>\n
  • High Staff Turnover<\/strong>: Different inspectors applied varying criteria, making standardization difficult.<\/li>\n
  • Lack of Traceability<\/strong>: Manual inspection did not allow for image storage or data tracking, complicating production management.<\/li>\n<\/ul>\n

    Solution & Key Technologies<\/strong><\/h3>\n

    Techman Robot\u2019s cobot arm provided an automated inspection solution, integrating advanced vision and AI classification technology to ensure precise glue application detection. Effectively solving the above drawbacks and achieving an automated workflow.<\/p>\n

          \n
        • TM AI Cobot were deployed to inspect the glue application on PCBs before the soldering machine process<\/li>\n
        • The cobot arm detected correct and incorrect dispensing, distinguishing between “OK” (properly applied glue) and “NG” (glue missing or misplaced)<\/li>\n
        • All images and inspection results were recorded in a database for traceability and process optimization<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
