Abstract
The invention belongs to the manufacture field of a crystalline silicon solar energy assembly, in particular to a method for welding a crystalline silicon solar energy assembly bus bar and an interconnector. The method for welding a crystalline silicon solar energy assembly bus bar and an interconnector comprises the following steps: arranging a plurality of cell strings provided with the interconnectors, and causing the interconnectors on the end part of the cell string to tidily expose; arranging bus bars on two ends of arranged cell strings; contacting and connecting the bus bars with the exposed interconnectors to form a plurality of contact points; respectively connectingthe positive electrode and the negative electrode of a high-frequency power supply with the interconnectors and the bus bars; forming a high-frequency current circuit by the high-frequency power supply, the interconnectors, the bus bars and the contact points; turning on the high-frequency power supply; controlling high-frequency current oscillation frequency to be more than 50kHZ; and cutting off the high-frequency power supply after the high-frequency power supply is turned on for 2-3 seconds to successively weld the interconnectors with the bus bars. The welding method has the advantages that skin effect generated by the high-frequency current is used for welding, product efficiency is improved, welding quality is good, and stability is high.
Description
Technical field
The invention belongs to the crystal silicon solar assembly and make field, the welding method of especially a kind of crystal silicon solar component bus bar and interconnector.
Background technology
In the crystal silicon solar battery component manufacture process; Must interconnector and busbar be welded together; The welding of busbar has crucial influence to the production efficiency and the quality stability of crystal silicon solar battery component, and the welding method of solar components busbar is manual welding at present, adopts electric iron to weld during manual welding usually; Production efficiency is low, and quality stability is poor.
Summary of the invention
The objective of the invention is shortcoming low to manual welding production efficiency in the above-mentioned technology, the quality stability difference; A kind of production efficiency is high, the good stability of quality the is high crystal silicon solar component bus bar and the welding method of interconnector are proposed; It has substituted the traditional hand welding, has the using value that is highly profitable.
The technical scheme that realizes the object of the invention is following:
The welding method of crystal silicon solar component bus bar and interconnector, this method may further comprise the steps,
A, some battery strings that are provided with interconnector are arranged, the interconnector of battery strings end is neatly exposed;
B, busbar is located at the two ends of the battery strings of arranging, and is connected the formation plurality of touch points with the interconnector contact that exposes;
C, the positive and negative electrode of high frequency electric source is connected with interconnector, busbar respectively, makes high frequency electric source, interconnector, busbar and contact point form the high frequency electric loop;
D, unlatching high frequency electric source, control high frequency electric frequency of oscillation is greater than 50kHz;
E, unlatching high frequency electric source 2-3 closed after second, and interconnector and busbar weld successfully.
Before opening high frequency electric source, interconnector and busbar are compressed through hold down gag.
What described interconnector and busbar adopted is copper tin band.
Adopted such scheme; Adopt high frequency electric source to weld, utilized the kelvin effect and the kindred effect of high frequency electric, high frequency electric produces local pyrexia in the bigger place of resistance; Interconnector and busbar welding energy needed is provided; The resistance of the contact point of the junction of interconnector and busbar is very big in addition, and high frequency electric generates heat at contact point, and interconnector and busbar are welded at contact point; Wherein the surge frequency range that adopts of high frequency electric is during greater than 50kHz, and kelvin effect is good more, and especially frequency is high more, and kelvin effect is obvious more, and welding effect is good more.
The invention has the advantages that through the kelvin effect of high frequency electric generation and weld, improved production efficiency, welding back quality is good, stability is high.
Description of drawings
The structural representation that Fig. 1 uses for the present invention;
Fig. 2 is the part vertical view of Fig. 1.
The specific embodiment
The welding method of crystal silicon solar component bus bar and interconnector, this method may further comprise the steps,
A, some battery strings that are provided with interconnector are arranged, the interconnector of battery strings end is neatly exposed;
B, busbar is located at the two ends of the battery strings of arranging, and is connected the formation plurality of touch points with the interconnector contact that exposes;
C, the positive and negative electrode of high frequency electric source is connected with interconnector, busbar respectively, makes high frequency electric source, interconnector, busbar and contact point form the high frequency electric loop;
D, unlatching high frequency electric source, control high frequency electric frequency of oscillation is greater than 50kHz;
E, unlatching high frequency electric source 2-3 closed after second, and interconnector and busbar weld successfully.
Before opening high frequency electric source, interconnector and busbar are compressed through hold down gag.
What described interconnector and busbar adopted is copper tin band.
Concrete operations are following, and like Fig. 1, shown in Figure 2, the battery strings 10,11,12 that welding is good is sequentially arranged on the glass 8 that is covered with EVA7; Battery strings is linked to be string by interconnector 1 with cell panel 2 and forms, so interconnector 1 forms exposed parts and parallel and orderly at battery strings 10,11,12 two ends, busbar 3 is placed on the exposed parts of interconnector 1 at battery strings 10,11,12 two ends; Busbar 3 forms contact point with every interconnector 1, on contact point, presses hold down gag 9, and the positive pole 4 of high frequency electric source 5 is connected on the busbar 3; Negative pole 6 is connected on the interconnector 1; This moment, interconnector 1, busbar 3, high frequency electric source 5 formed current loops, opened high frequency electric source 5 then, and the frequency of oscillation of control electric current is during greater than 50kHz; The contact point of high frequency electric under hold down gag 9 produces kelvin effect; Heat takes place, and material is that the interconnector 1 of copper tin band welds success with busbar 3 when heat acquires a certain degree, and electric current is 2-3s or 4 seconds conduction time.
The frequency of above-mentioned high frequency electric during greater than 50kHz effect obvious, especially greater than 60kHz or greater than 70kHz, 100kHz or the like, better effects if when greater than 700kHz.
The positive pole 4 and the negative pole 6 of above-mentioned high frequency electric source 5 can be connected on interconnector 1 and the busbar 3.
Above practical implementation thing be of the present invention a kind of for example, the present invention includes but be not limited to above-mentioned true example, the scope that the improvement that task is carried out all belongs to the present invention to be protected on basis of the present invention.
