[0002] In the production process of photovoltaic modules, at least one EL detection process is usually arranged to detect abnormal conditions of photovoltaic modules, including internal defects, hidden cracks, fragments, cold solder joints, broken grids, etc. The principle of EL detection is to energize the photovoltaic module to stimulate the internal cells of the photovoltaic module to emit infrared light. The infrared light emits pattern light according to the performance of the cell. The infrared light is collected and imaged by the camera equipment. Based on the imaged image, the defects of the photovoltaic module can be seen.

[0003] Most of the existing EL detectors are single-path groups that detect the output of the EL string power supply through wires, and the wires are tangled together when placed. When storing, the tangled wires need to be untangled, which affects the detection efficiency of the EL detector. In addition, the existing EL detectors are placed on the ground for detection. When the ground is wet, the EL detectors placed on the ground are prone to water ingress, which affects the service life of the EL detector. Summary of the invention
