Single welding and series welding integrity device of solar cell slices

Abstract

The invention discloses a single welding and series welding integrity device of solar cell slices. The provided single welding and series welding integrity device of the solar cell slices is good in positioning accuracy and compatible in the solar cell slices with different specifications, and can improve the single welding and series welding production efficiency of the solar cell slices. The device comprises a device rack, the device rack is provided with a feed mechanism, a transmission and positioning mechanism, a welding and temperature control mechanism, a blanking mechanism, a control mechanism and a power supply and control mechanism. According to the single welding and series welding integrity device of the solar cell slices, a full manual welding mode is replaced by a full automatic mechanical welding mode, the production efficiency is remarkably increased, the cell slice failure rate during a welding process is reduced, and the device is suitable for cell slice welding of the solar cells.

Description

technical field [0001] The present invention relates to a welding device for solar cells, more specifically, to an integrated device for single welding and series welding of solar cells. Background technique [0002] With the development of social economy and the improvement of people's living standards, people's demand for energy continues to increase. With the shortage of non-renewable energy such as coal, oil, and natural gas, the energy problem has become the primary problem restricting the economic development of various countries. Driven by the international photovoltaic market and the policy support of governments around the world, the photovoltaic manufacturing industry is booming. my country's solar cell and module manufacturing industry is also advancing at an alarming rate. The complete photovoltaic manufacturing industry chain is: silicon material —> crystal pulling, ingot casting —> raw silicon wafer —> cleaning, diffusion, etching, PE, screen printin...
