Description

Technical Field

[0001] The utility model relates to the technical field of defect detection of solar cell sheets, in particular to a defect detection and placement platform for solar cell sheets. Background Art

[0002] Solar energy is a green and clean energy, and photovoltaic power generation technology has attracted much attention in my country. In the manufacturing process of photovoltaic panels, mechanical stress, thermal stress, human operation errors and other unknown factors may lead to a series of quality defects, such as microcracks, fragmentation, broken grids and dark spots. The existence of these quality defects not only reduces the power generation efficiency and service life of solar cells, but also may increase the safety risks when using electricity. In addition, the use of defective cells may also have a negative impact on the economic benefits and brand image of the enterprise. Therefore, ensuring the quality of solar panels is crucial to ensure their performance, safety and economic benefits.

[0003] Electroluminescence is the phenomenon whereby a substance emits light when exposed to an electric current or strong electric field. In solar cells, infrared light is emitted from the surface of the cell when a reverse bias voltage is applied. Specialized cameras, usually sensitive to infrared light, are used to capture images of the cell's luminescence. These cameras are able to detect changes in luminescence intensity and distribution that indicate various defects, such as microcracks, dark flakes, stains, and broken grids.

[0004] For example, the prior art (patent number CN 206177835U) discloses a device for detecting photovoltaic cell defects based on the electroluminescence principle, which can quickly detect structural defects of silicon or gallium arsenide solar cells, facilitate analysis and problem solving, and improve product quality and efficiency.

[0005] The prior art is provided with a pair of parallel rails, on which the battery detection platform can move back and forth, and can be moved to the bottom of the dark box, and the lifting of the hydraulic lifting device can drive the energized guide rod to rotate. When adjusting the back and forth movement and lifting, there are great limitations, which may cause the camera to collect incomplete image data of the corners of the solar cell, which is not conducive to the comprehensive detection of defects in the solar cell. Therefore, we propose a new type of solar cell defect detection and placement platform. Utility Model Content
