Badminton Racket Non-destructive Testing
Applications
Aug 13,2026
System introduction
The badminton racket infrared thermal imaging non-destructive testing system is composed of three modules. The thermal excitation module uses halogen lamps or hot air guns with adjustable heating distance and power for uniform or localized heating. The infrared acquisition module is an uncooled HJK-LWIR infrared thermal imager with a resolution of no less than 640×512 and thermal sensitivity better than 0.05°C, capable of real-time surface temperature field acquisition. The intelligent analysis module features a built-in deep learning segmentation algorithm that automatically identifies paint-loss and paint-repair areas, outputs defect locations, contours, and areas, and generates inspection reports. The system operation workflow is as follows: fix the racket, apply thermal excitation, capture with thermal imager, run algorithm analysis, and output results. Traditional manual visual inspection of badminton racket surface defects suffers from low efficiency, high subjectivity, and inability to quantify defect boundaries. However, this advanced system, based on infrared thermography technology, can effectively address the above issues.
Product features
1. Non-contact and non-destructive: No contact with the racket surface, avoiding mechanical scratches or contamination, suitable for final inspection of finished products.
2. Precise surface defect identification: Obvious temperature differences between paint-loss and paint-repair areas, clear thermal image boundaries, combined with deep learning algorithms to automatically frame defects and eliminate human misjudgment.
3. High inspection efficiency: Single inspection takes 5–8 seconds, supporting continuous batch screening.
4. Mature and reliable equipment: HJK-LWIR infrared thermal imagers offer high cost-effectiveness, simple operation, no need for cooling, and are suitable for long-term operation in production line environments.
5. Traceable data: Each racket generates an inspection report including thermal images, defect annotations, and temperature curves, facilitating quality traceability.
Application
The system captures infrared radiation from the badminton racket surface and converts it into visual thermal images. Defect locations, types, and extents are identified through temperature distribution characteristics. Each inspection takes approximately 5–8 seconds, making it suitable for batch sampling on production lines, laboratory process validation, and quality assessment applications.
Equipment value
1. For surface coating defects such as paint loss and paint repair, this system provides an automated solution based on long-wave infrared thermography combined with intelligent image recognition. The entire process requires no contact with the racket and does not rely on manual subjective judgment.
2. Paint-loss areas: The absence of surface coating results in differences in thermal absorptivity and emissivity compared to intact paint surfaces. After excitation by halogen lamps or hot air guns, the surface temperature difference is significant, and the boundaries and extents can be clearly distinguished in infrared thermal images.
3. Paint-repair areas: The repaired coating differs from the original paint in material and thickness, resulting in different thermal conductivity characteristics. After heating, the surface temperature distribution becomes uneven, and the infrared thermal imager can stably identify the location and contour of paint-repair areas.
