Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to an infrared flaw detection platform for photovoltaic components. Background Art

[0002] In the production and quality control of photovoltaic modules, infrared flaw detection technology plays a vital role. This technology uses the characteristics of infrared rays to penetrate the surface of photovoltaic modules and deeply detect their internal structures. When there are defects or damage inside the modules, the thermal conductivity of these areas will change, forming obvious abnormal areas on the infrared images. By comparing the infrared images of normal modules with abnormal modules, defects and damage inside the modules can be quickly identified, providing strong support for quality control in the production process.

[0003] However, traditional flaw detection platforms have shortcomings in fixing photovoltaic modules and adjusting the height of flaw detectors. Photovoltaic modules are prone to shaking or dislocation due to unstable fixation during the flaw detection process, resulting in inaccurate flaw detection results. At the same time, photovoltaic modules of different sizes require flaw detectors of different heights to make infrared rays cover the entire photovoltaic panel, and traditional platforms often cannot be flexibly adjusted. Therefore, an infrared flaw detection platform for photovoltaic modules is proposed. Utility Model Content
