In modern manufacturing, glue is used as an important joining and sealing material, and the accuracy and quality of its application is directly related to the overall performance and reliability of the product. However, problems such as multiple glues, leaks and overflows occur from time to time during the manufacturing process. These problems not only affect the appearance of the product, but may also have a serious impact on the functionality and safety of the product. In order to effectively solve these problems, telecentric lenses, as a high-precision, low-distortion imaging system, are widely used in the field of glue inspection, realizing the accurate identification and monitoring of problems such as multiple glues, leaks and overflows.

Advantages of telecentric lens

1. High-precision imaging: Through its unique optical design, the telecentric lens is able to maintain a high degree of image consistency at different working distances, effectively eliminating image aberrations caused by changes in object distance and ensuring the accuracy of inspection results.
2. Large depth of field: telecentric lenses have a large depth of field range, able to clearly image all objects within a certain range, which is particularly important for the detection of uneven surfaces or highly variable glue applications.
3. Low distortion: Compared with traditional lenses, telecentric lenses produce very low distortion during the imaging process, ensuring the authenticity and reliability of the inspection image and providing a solid foundation for subsequent image processing and analysis.

Application Scenario

1. Multi-glue detection: On the production line, a machine vision system installed with telecentric lenses can monitor the amount of glue being applied in real time, and detect and correct excessive glue application in a timely manner. The system is able to accurately identify glue areas that exceed preset standards and issue an alarm or automatically adjust the gluing equipment to ensure that the amount of glue applied to each product is within reasonable limits.
2. Glue Leakage Detection: For products that need to be tightly sealed or connected, glue leakage is a problem that cannot be ignored. The high-precision imaging capability of the telecentric lens allows even tiny glue leaks to be clearly captured. Through image processing algorithms, the system is able to automatically identify and mark areas of glue leakage, providing production personnel with intuitive feedback so that timely measures can be taken to remedy the situation.
3. Spillage Detection: During glue application, spillage not only affects the aesthetics of the product, but may also contaminate or damage other parts of the product. The telecentric lens, combined with advanced image processing technology, can accurately identify the overflowed glue, measure its area and location, and provide detailed inspection reports for production personnel to make targeted improvements and optimization.

The application of telecentric lenses in glue inspection greatly improves inspection accuracy and efficiency, bringing significant quality improvement and cost savings to the manufacturing industry. By accurately identifying problems such as multiple glues, leaks and overflows, the telecentric lens provides strong support for the automation and intelligence of production lines.
