Portable photovoltaic fault diagnosis and detection device

Abstract

The invention discloses a portable photovoltaic fault diagnosis and detection device comprising a CCD camera. A convex column is fixedly connected on the bottom part of the CCD camera. A concave post is connected on the side surface of the convex post in a threaded way. A disc is fixedly connected on the bottom part of the concave post. A fixed disc is flexibly connected on the side surface of the disc. The side surface of the fixed disc is provided with a threaded hole. A fixing screw is connected on the inner wall of the threaded hole in a threaded way. A fixing post is fixedly connected on the bottom part of the fixed disc. According to the portable photovoltaic fault diagnosis and detection device, the CCD camera, the convex post, the concave post, the disc, the fixed disc, the threaded hole and the fixing screw are arranged so that that photovoltaic surface fault can be conveniently detected and diagnosed by the CCD camera, and the photovoltaic detection device can be conveniently carried by arrangement of the clamp plate, the connecting rod, the supporting rod, the sliding block, the movable rod, the circular rod, the fixed rod, the fixed disc, the groove, the first thread groove, the second thread groove, the fixed column and the handle.

[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
