[0002] With the widespread use of photovoltaic technology, the photovoltaic modules used to carry the smooth implementation of photovoltaic technology and the quality of the photovoltaic modules have become the core issues of the photovoltaic industry. In recent years. With the rapid growth of green energy demand, China The output of solar panels in China is continuing to expand rapidly. At present, there are more than 500 enterprises in China producing solar panels and components. Among them, many large enterprises already have the production capacity of silicon materials. At present, silicon solar panels are usually It is made of sliced ​​single crystal rods, but due to the high cost of single crystal silicon, in order to save silicon materials, the slices are usually cut very thin. The thickness of silicon wafers from most manufacturers is about 200txm. Yingli Group has achieved a thickness of about 180txm. The repeated processing of cells by the automated production line will increase the damage rate of cells, and defects such as cracks, fragments, chipping, virtual welding, and broken grids will occur during the production process, which will make the conversion efficiency of solar cells even higher. If it can be found in time in each production process, the operating status of the production equipment can be adjusted accordingly, thereby improving the qualified rate and grade of finished products. This requires a large number of online defect detection equipment. For cost considerations, the current Most of the production lines only do an EL test before lamination and after lamination, so the development of online defect detection equipment with low development cost, fast scanning speed, and high imaging definition has become a key issue in the production process of solar panels. The development of this equipment will have an important impact on the development of the photovoltaic industry. Generally, EL side-view instruments are used, but the EL side-view instrument is very inconvenient to move. It can be moved in a short distance, but it is easy to use when moving a long distance or changing positions The support device under the detection device bumps and bumps when moving, and may damage the detection device during the movement, which is inconvenient to carry
