In solar photovoltaic module factories, due to cost control, it is urgently needed to realize an automatic electrical performance test function of a photovoltaic module so as to save labor cost. At present, more than 1000 production lines exist in China photovoltaic module factories, and automatic testing cannot be basically realized or serious measurement errors exist. At present, the temporary solution of a photovoltaic module factory is as follows: 1, adopting a scheme that the test tool needs to be completely replaced or partially replaced every two months or three months; but the operators of the electrical performance testing station can not be saved, the loss of the testing jig exceeds 10 ten thousand yuan per production line every year, and the labor cost is more than 25 ten thousand yuan; in addition, the component sales income caused by uncontrollable measured deviation is greatly lost; 2, or most manufacturers arrange that operators manually plug and unplug the lines or sit below a production line with the height not more than one meter, and the labor cost of each production line is more than 25 ten thousand per year, which is not good for the health of the operators.
Under the current conditions, some manufacturers equip a plurality of automatic tools on each production line, and equip a probe method or a pin inserting method on an electrical property tester to complete the scheme of automatic test functions. Because the metal contact head designed by the existing tool has surface change caused by high-voltage contact or position deviation after EL measurement and high-voltage resistance measurement of production line circulation every time, resistance change between test contact systems connected with a solar simulator is further caused, so that the resistance of the tool on each production line is different after the tool is used for many times, the resistance deviation cannot be corrected by standard component calibration caused by the resistance change, and finally the measurement uncertainty of component products on the production line is increased. The cost of each production line is consumed by more than dozens of ten thousand yuan each year; after the existing test tool on the market is added, the cost is increased to be higher; the existing test tool is not added, and the operator is not good for the body of the operator because the operator needs to sit below the assembly line with the height of one meter.
