Abstract
The invention relates to the technical field of solar photovoltaics and particularly relates to a process and equipment for manually welding solar components. In the process, a battery piece and a solder strip are preheated in advance, so that the possibility that battery piece subfissure and fragments are caused by temperature impact which is caused when the battery piece is suddenly in contact with a high-temperature electric solder tip is reduced; springs are additionally arranged at a solder tip used in the equipment and a handle solder tip, so that the possibility that battery piece subfissure and fragments are caused by relatively high force impact or pressure exerted on the battery piece due to different operating forces of different operating workers is avoided, the product breakage rate is obviously reduced, the electric properties of the components are improved, the technology method is simple, the effect is obvious, and the equipment is applicable to wide popularization and application.

The electric soldering bit used in prior art does not have resiliency, because the operating force of different operative employees is different, dynamics is excessive easily to be formed shock more energetically or pressure to cell piece thus causes that cell piece is hidden to be split and fragment, and dynamics is too small, and easily not prison welding causes welding to snap and sealing-off.
The electric soldering bit temperature used in prior art is general all could by the melts soldering tin on tin-coated welding strip 380 DEG C (the difference slightly differences according to wlding material), more than 400 DEG C are generally needed to argentiferous tin-coated welding strip, and the temperature of cell piece itself follows environment temperature close to (usual room temperature is constant in 25 ± 2 DEG C), the solar cell piece welded, string array are placed in room temperature and naturally cool.
So prior art also exists the undesirable problem of welding breakage rate power output that is high and assembly.
(2) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides and a kind ofly welds the low solar components manual welding Processes and apparatus of breakage rate.
The present invention is achieved through the following technical solutions:
A kind of solar components manual welding technique, comprises the steps:
(1) preheat cell piece and welding, heating platen temperature is set to: 70 ± 5 DEG C, and cell piece and welding are preheated to 60 ~ 70 DEG C;
(2) single weldering: convergent belt is welded in the main gate line of cell piece front (negative pole), convergent belt is for being coated with tin copper strips, and the length of convergent belt is about 2 times of cell piece, is connected when the convergent belt had more welds overleaf with the backplate of cell piece below;
(3) series welding: N is opened cell piece and to be serially connected formation battery strings, the location of battery is mainly by a Die and mould plate, operator uses electric iron to be welded in the backplate (positive pole) of cell piece below by the front electrode (negative pole) of the cell piece welded, and so successively N is opened cell piece and is serially connected and goes between at the both positive and negative polarity weld of battery strings;
(4) use interconnecting strip that the battery strings welding of having welded is formed crystal-silicon solar cell array;
A kind of solar components manual welding equipment, comprises welding stage and electric iron, it is characterized in that: the solder horn of described electric iron and handle flatiron heart place install additional one be with buffer memory, have flexibility, resistant to elevated temperatures spring.
The invention has the beneficial effects as follows: the invention provides a kind of solar components manual welding Processes and apparatus, in technique, cell piece and welding are first preheated, reduce cell piece because of touch suddenly high temperature Electric iron head caused by temperature shock and cause cell piece hidden split with fragment may, the solder horn that equipment uses and handle flatiron heart place add shock mount, the operating force avoided because of different operating employee is different, shock more energetically or pressure are formed to cell piece thus cause cell piece hidden split and fragment may, the breakage rate of product obviously declines, the electrical property of assembly is improved, process is simple, successful, be suitable for wide popularization and application.
Verify below by way of contrast experiment:
The cell piece of the same model selecting same company to produce (each sample is 4 groups, often organizes 60) adopts manual welding technique of the present invention and prior art to weld respectively, and adds up cell piece breakage rate and power (%) is as follows:
Known by above-mentioned experiment, welding quality of the present invention is significantly improved, and the breakage rate of product obviously declines, and the electrical property of assembly have also been obtained raising, achieves the object of invention.
