Description

technical field [0001] The invention relates to the technical field of photovoltaic module manufacturing equipment, in particular to a solar photovoltaic cell stringing device and a stringing method based on the stringing device. Background technique [0002] The production process of photovoltaic modules is as follows: use interconnection strips to connect photovoltaic cells in series to form battery strings, and then collect battery strings into battery strings according to polarity through busbars, so as to achieve the required current and voltage output conditions, and finally through lamination Encapsulated into photovoltaic modules. [0003] At present, the commonly used battery string welding method is to use an automatic stringer to weld the front electrodes of the solar cells and the back electrodes of the front and rear side cells through the interconnection strips, and then connect the batteries with different polarities at the upper and lower ends of the module t...

AI Technical Summary

Problems solved by technology

In the actual production process of the battery strings of the automatic stringer, the above-mentioned battery string series connection method must first connect the positive electrode on the back of the battery to the interconnection bar, but cannot firstly connect the negative electrode on the front of the battery to the interconnection bar, which leads to the automatic stringer. It can produce battery strings with the same polarity on the same side, and one string of battery strings must be rotated during the assembly process, and then connected in series with the other string by manual welding; this kind of automatic string welding device must be connected in series After the battery string is rotated by 180°, the subsequent busbar welding operation can be carried out, and the busbar welding must be done manually

[0004] The above-mentioned stringing device reduces the production efficiency of the components to a certain extent, and the manual welding method reduces the performance of the product. Therefore, a new type of solar photovoltaic cell stringing device is urgently needed to solve the above-mentioned existing problems
