Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module testing technology, and in particular to a spectroscopic detector for bonding defects in ultra-thin photovoltaic modules. Background Technology

[0002] In the production process of photovoltaic modules, the bonding process is one of the key links affecting the quality of the modules. Bonding defects can lead to decreased module efficiency, shortened lifespan, and even safety hazards. Traditional testing methods mainly rely on manual visual inspection or X-ray inspection, which have problems such as low efficiency, high cost, and radiation hazards. Spectroscopic detection technology, as a non-contact and non-destructive testing method, has broad application prospects in the field of photovoltaic module testing.

[0003] Existing ultra-thin photovoltaic module bonding defect spectrometers typically require visual inspection by operators. When photovoltaic modules are being tested for bonding defects, the modules are prone to micro-displacement due to uneven stress, causing fluctuations in spectral data. At the same time, photovoltaic modules are prone to releasing harmful gases during bonding defect testing, posing a safety hazard to workers.

[0004] Existing spectroscopic detectors for bonding defects in ultra-thin photovoltaic modules typically require visual inspection by operators. During bonding defect detection, the modules are prone to micro-displacement due to uneven stress, causing fluctuations in spectral data. Furthermore, the detection process can release harmful gases, posing safety hazards to workers. This solution addresses this by incorporating a self-adjusting clamping detection structure. By placing the photovoltaic module inside the spectroscopic detector, the system automatically detects and clamps the module, eliminating the need for operator contact and significantly increasing the efficiency of bonding defect detection.
