Abstract
The invention belongs to the technical field of mechanical equipment, and relates to pipe fitting components of a solar module, in particular to an L-type plane bending solder strip for the solar module. The L-type plane bending solder strip for the solar module comprises a solder strip body integrally formed by a first edgefold and a second edgefold, the first edgefold and the second edgefold form a 90-degree angle, and the crossing portion of the two edgefolds of the solder strip body is circular arc transition. The L-type plane bending solder strip for the solar module can reduce welding procedures of a user, improves production efficiency, reduces overlapped portions of soldering, lowers electrical resistivity, improves transfer efficiency of a component, reduces soldering joints to enable the whole component to be more attractive in appearance, and improves the component level. Therefore, the development of the L-type plane bending solder strip is one of the keys of improving generating efficiency and levels of a photovoltaic module and saving production process cost, and is development tendency of oncoming products.
Description
Technical field
The invention belongs to mechanical equipment technical field, relate to the pipe fitting parts of solar components, specifically a kind of solar components " L " type plane bending welding.
Background technology
Solar cell is a kind of very promising novel power supply, and it has permanent, spatter property and flexibility three big advantages. solar battery life is long, as long as the sun exists, solar cell just can once be invested and long-term the use; Compare with thermal power generation, nuclear energy power generation, solar cell can not cause environmental pollution; Solar cell can be realized large, medium and small combination easily, arrives the medium-sized power station of gigawatt greatly, and little of the solar battery group of only using for a family, this is that other power supply is incomparable.Along with the emergence of domestic photovoltaic industry, be the emphasis that whole photovoltaic industry is paid close attention to as the core light photovoltaic assembly of photovoltaic generation.The cost, the raising assembly grade that how to improve the generating rate, reduce in the production process will be the keys of making the solar power generation assembly.Then it plays an important role as the connecting line (being coated with tin copper strips busbar) of indispensable series-connected cell sheet power output in the assembly.Being coated with tin copper strips busbar needs the electric weight of all battery sheets is delivered to terminal box in whole assembly, because the characteristic of its connection has determined it must form " L " right angle, existing pattern is that photovoltaic module gathers part with welding, adopt two root bead bands of different length manually to be welded into " L " use, welding causes cost of labor increase, inefficiency, outward appearance is coarse, resistance increases influences conversion efficiency.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of solar components simple and reasonable for structure with L type plane bending welding, this welding can one-shot forming, have that resistance is little, the client need not directly use of welding, appearance looks elegant, raising product hierarchy, increase advantages such as competitiveness.
According to technical scheme provided by the invention: a kind of solar components of the present invention is with L type plane bending welding; be characterised in that: comprise by first flanging and the one-body molded welding body that constitutes of second flanging; described welding body is followed successively by copper layer, tin layer, protective film from inside to outside; described first flanging and the second flanging shape at an angle of 90, and the welding body is arc transition two flanging intersections.
As a further improvement on the present invention, described welding body surface is smooth smooth.
As a further improvement on the present invention, described welding body surface is coated with the tin layer.
The present invention compared with prior art, advantage is: (1) can be saved client's welding sequence and enhance productivity; (2) having reduced the welding overlapping part has reduced resistivity and has improved the assembly conversion efficiency; (3) reduced welding point and made the whole assembly outward appearance assembly grade that promoted more attractive in appearance.So the exploitation of " L " type plane bending welding is to improve one of key of photovoltaic module generating efficiency, grade and saving production process cost, the development trend of future products especially.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is welding body construction schematic diagram.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2, welding body 1, first flanging 2, second flanging 3 etc.
The present invention relates to a kind of solar components " L " type plane bending welding; comprise by first flanging 2 and second flanging, the 3 one-body molded welding bodies 1 that constitute; described welding body is followed successively by copper layer, tin layer, protective film from inside to outside; described first flanging 2 and second flanging, 3 shapes at an angle of 90, and welding body 1 is arc transition two flanging intersections.
Described welding body 1 surfacing is smooth.
Described welding body 1 surface applied has the tin layer.
" L " type plane bending welding is formed through surface applied tin lead or lead-free alloy greater than 99.95% copper base material by purity, and finished surface is smooth, smooth, color and luster is even.In " L " type plane bending welding production process, start with from technology, equipment, width is bent into " L " type with in-plane at the tin copper strips busbar that is coated with of 4mm ~ 8mm under the constant prerequisite of other performances, make it when client is used, need not secondary operations, not having extra resistance when component power is carried increases, when the assembly grade classification, stop to cause degradation because of the bad order that welding brings, improve client's production efficiency, help the client to save cost and enlarge profit space, improve self product competitiveness.
Be used as " L " type plane bending welding copper base material requires:
1) copper content 〉=99.95%
2), resistivity TU1≤0.0168 Ω mm2/m; T2≤0.017241 Ω mm2/m
The coating alloy composition:
The plumbous series of tin: tin 60% lead 40%, tin 63% lead 37%, tin 62% plumbous 36% silver medal 2%
Unleaded series: tin 97% silver medal 3%
" L " type plane bending welding the key technical indexes:
1), " L " type plane bending welding is 90 ° of right angle weldings;
2), " L " type plane bending welding forms for automatic bending after being coated with tin;
3), " L " type plane bending welding do not have the welding overlapping point be one-shot forming;
4), the surfacing of " L " type plane bending welding is smooth,
This product can be saved client's welding sequence and enhance productivity, and has reduced the welding overlapping part and has reduced resistivity and improved the assembly conversion efficiency, has reduced welding point and has made the whole assembly outward appearance assembly grade that promoted more attractive in appearance.So the exploitation of " L " type plane bending welding is to improve one of key of photovoltaic module generating efficiency, grade and saving production process cost, the development trend of future products especially.
