Abstract
A bending device for a solar cell bus bar comprises a bus bar feeding groove allowing the bus bar to pass through. The bus bar feeding groove comprises a groove body and a cover plate. The groove body is used for bearing the bus bar. The cover plate covers the groove body, and extends toward the outlet side of the bus bar feeding groove to cover the bus bar. A rolling roller is correspondingly arranged on the outlet side of the bus bar feeding groove, and comprises a first pressure roller and a second pressure roller. The diameter of the first pressure roller is larger than that of the second pressure roller. A part of the first pressure roller is positioned below the cover plate. The first pressure roller and the cover plate are arranged at an interval to form a rolling groove allowing the bus bar to pass through. The rolling roller is rotationally supported by an eccentric shaft of an eccentric mechanism. A rotating shaft of the eccentric mechanism is in transmission connection with an output shaft of a driving device. The long-stripped bus bar is bent into an L-shaped bus bar directly through the bending device, and the bending device has the advantages of being less in manufacturing procedure, convenient to operate, and efficient.
Description
Technical field
The present invention relates to a kind of solar cell busbar apparatus for bending, belong to photovoltaic equipment technical field.
Background technology
Since 21 century, global Energy Consumption sharply rises, and traditional fossil energy is day by day exhausted, and energy problem and environmental problem become two large Important Problems of global concern gradually.Under the pressure of the pressure of sustainable development, solar photovoltaic industry is listed in the emphasis that regenerative resource develops by each major country one after another.Become the second in the world economy along with China, in October, 2013, China's petroleum import in October amount reaches every day 6,300,000 barrels, exceedes the every day 6,240,000 barrels of the U.S., and replacing the U.S. first becomes global maximum net import of oil state.2013, the external dependence degree of CNPC and natural gas reached 58.1% and 31.6% respectively, and China has become global the third-largest natural gas consumption state.Traditional fossil energy is more and more difficult to the thriving demand meeting Chinese national economy.In in the past 20 years, the artificial CO2 emissions in the whole world nearly about 75% derive from combustion of fossil fuel.Therefore, be no matter the energy development angle from low-carbon environment-friendly, still comply with Industry Structure upgrading and transition pressure, China must accelerate development New Energy Industry.
Solar energy belongs to clean reproducible energy.According to " European renewable energy technologies strategic plan " that EU Committee proposes, to the year two thousand twenty, solar energy will account for 15% of European Union's electricity needs.2010, USDOE developed planning, and planned the year two thousand thirty, and solar energy accounts for 10% ~ 15% of total energy consumption figure.Take temperature from worldwide solar energy and the generating of tide energy aggregate net, China is 3,000,000,000 kilowatt hours, and Germany is 19,000,000,000 dry watt-hours, and Italy is 10,700,000,000 dry watt-hours, and Spain is 9,100,000,000 kilowatt hours, and Japan is 3,800,000,000 kilowatt hours.Following China water power growth space is limited, and nuclear energy exists unsafe factor.Fossil energy will rise by energy-saving and emission-reduction committed cost, the wide market of solar energy power generating.
In order to obtain required electric current, voltage and power output, in current photovoltaic industry, need the practical application product that can become power supply output after being connected by solar battery sheet after the technique such as stacked, lamination, encapsulation formation solar module.In crystal silicon solar battery component manufacture process, first with interconnector, solar battery sheet must be welded into solar cell string, then by multiple solar cell string marshalling, next welded by the interconnector that busbar and the end of multiple solar cell string are stretched out, electric current can be collected in terminal box outwardly to provide electric power by busbar.
The material of busbar is generally and is coated with tin copper strips, and shape is generally L shape, the limit that L shape busbar is wherein longer and solar cell string interconnected, shorter limit and terminal box interconnected.The preparation method of L shape busbar is: prepare two sections of busbars, be then placed on the stainless steel mould plate of track, two sections of busbars partly overlap, and becomes 90 degree of placements, and then welds with electric iron and solder stick.The shortcoming of this production method is: due to needs by busbar cutting, partly overlap 90 degree of placements, the operation of therefore welding is more, and welding efficiency is low, and easily produces overlap in welding process.
