Description

Technical Field

[0001] The utility model relates to the technical field of EL single string testing devices, in particular to an EL single string testing device for an automatic string welding machine. Background Art

[0002] EL detection device, full name electroluminescence detection device, is a device that works based on the electroluminescence phenomenon and is mainly used to detect internal defects or faults in photovoltaic modules, electronic components and other electronic equipment.

[0003] The working principle of the EL detection device mainly includes the following steps: first, the photovoltaic module to be tested is connected to the charging power supply of the EL detection device, current is supplied to it and it is charged to a specific voltage level. Then, the photovoltaic module is activated by high-voltage discharge to generate electroluminescence. The emitted light can reveal defects or faults on the surface of the photovoltaic module. Then, the EL detection device uses a high-resolution image sensor and camera to capture this light to form an EL image. Finally, by analyzing these images, various defects, cracks, hot spots and other problems can be detected and identified.

[0004] In the above scheme, the existing EL detection device is usually used to detect photovoltaic modules, and photovoltaic modules usually include multiple strings of cells and packaging frames. If defects, cracks, hot spots and other problems are detected in the photovoltaic modules, the photovoltaic modules need to be disassembled and the problematic cells need to be repaired or replaced. This operation is relatively cumbersome and the efficiency of repairing or replacing the cells is low. Utility Model Content
