Abstract
The invention relates to a high-frequency current direct heating soldering method for a crystalline silicon solar cell. The method comprises the following steps: a solar cell with flux and solder strips on upper and lower end faces of the solar cell are superposed on a preheat panel to ensure that the solder strips are contacted with a main grid line of the solar cell; the solder strips and the cell are pressed with each other through a press device; the solder strips are connected to a high-frequency current heat circuit to ensure that the solder strips are used as a part of the high-frequency current heat circuit; the high-frequency current heat circuit is connected, due to the skin effect of high-frequency current, when the high-frequency current passes through the solder strips, the solder strips are heated and provides heat to grids of the solar cell and the solder strips on the lower end of the solar cell through thermal conductivity, so that the grids of the solar cell and the solder strips on the upper and lower ends of the solar cell can be soldered together. By the skin effect of the high-frequency current, the heating speed is accelerated, so the current directly emits heat through the solder strips. The soldering method has high heating speed, good solder quality and high production efficiency.

Technical field
The high frequency electric that the present invention relates to a kind of crystal silicon solar energy battery directly heats welding method, is used for the welding of solar cell chip module manufacture process battery sheet, is particularly useful for the welding of crystal silicon solar cell sheet string.
Background technology
In the crystal silicon solar battery component manufacture process, must be with battery sheet welding bunchiness, the welding of battery sheet and battery sheet string has crucial influence to the production efficiency and the quality stability of crystal silicon solar battery component, present crystal silicon solar cell sheet and battery sheet string adopt welding method to have: a kind of is the method welding of manual welding: adopt electric iron to weld during manual welding usually, production efficiency is low, and quality stability is poor; Another kind is to adopt the infrared thermal weld that adds, and speed of welding is slower, and battery sheet integral body is heated, and is yielding, easily causes the fragmentation of battery sheet, and energy consumption is big; Also have another method to adopt HFI welding exactly, in welding, produce eddy current by radio-frequency induction coil and weld.
Summary of the invention
At above-mentioned technical problem, the high frequency electric that the purpose of this invention is to provide the crystal silicon solar energy battery that a kind of firing rate is fast, welding quality good, production efficiency is high directly heats welding method.
Realize that technical scheme of the present invention is as follows:
The high frequency electric of crystal silicon solar energy battery directly heats welding method, may further comprise the steps:
Step 1: the solar battery sheet that will have solder flux places on the preheating table with the welding stack that is positioned at the solar battery sheet upper and lower end face, and welding is contacted with the main grid line of solar battery sheet;
Step 2: above-mentioned welding and battery sheet are compressed mutually with hold down gag;
Step 3: welding is connected in the high frequency electric heater circuit, makes welding as the part in the high frequency electric heater circuit;
Step 4: connect the high frequency electric heater circuit, because the kelvin effect of high frequency electric, when high frequency electric flows through welding, welding is heated and by heat conductivity heat is offered the grid of solar battery sheet and the welding of solar battery sheet lower end, thereby the grid of solar battery sheet and the welding of solar battery sheet upper and lower side are welded together.
The sectional area of wire of described high frequency electric source is greater than the welding sectional area.Big many of the resistance of the resistance ratio high frequency electric source lead at welding place like this, according to the kelvin effect of high frequency electric, the upper strata welding is just heated rapidly, thereby crystal silicon solar cell sheet and lower floor's welding also are heated simultaneously.
Described hold down gag comprises a plurality of fastening bodies, and described a plurality of fastening bodies are pressed on the upper surface of upper strata welding uniformly, can guarantee that like this solar battery sheet can catch up with the welding of lower floor and closely contact.
The positive and negative electrode of described high frequency electric source is separately fixed on the electric conductor of fastening body end at welding two ends, upper strata.
Described fastening body is flexible depression bar.
Frequency of oscillation＞the 50kHz of described high frequency electric source.
Adopt such scheme, the solar battery sheet and the welding stack that will have solder flux place on the preheating table, welding is contacted with the main grid line of solar battery sheet, with hold down gag welding and battery sheet are compressed mutually, the positive and negative electrode of high frequency electric source is directly joined with the two ends of welding respectively, make welding as the part in the high frequency electric loop, when high frequency electric flows through, the upper strata welding is heated, and battery sheet and lower floor's welding also are heated simultaneously, thereby welding and battery sheet are welded together.The present invention utilizes the kelvin effect of high frequency electric, just when high frequency electric passes through welding, electric current will be tending towards the welding surface and flow through, and accelerate electrothermal calefactive rate, make electric current directly by the welding heating, this welding method firing rate is fast, welding quality good, production efficiency is high.
