Abstract
The invention relates to a processing method for an extra-soft tinned copper belt for a solar cell. The processing method comprises the following steps of: slitting a hard copper plate belt, continuously light annealing, cleaning, tinning, QC (quality control) examining, cleaning the tinned belt, weighing and packing. The invention has the following characteristics that: the extra-soft tinned copper belt processed by the invention is substantially different from a common tinned copper belt in terms of hardness and tensile strength of a substrate. The hardness of a common tinned copper belt is only 50 degrees. The common tinned copper belt is scrolled in a splitting manner and the hardness of the copper belt is greatly changed by an external force in the splitting process. The hardness of the common copper belt before being tinned is increased to probably be 53-54. A process for slitting the extra-soft tinned copper belt firstly and heating the extra-soft tinned copper belt secondly is executed in the processing method disclosed by the invention, so that the softness of the tinned copper belt finished product is guaranteed. Meanwhile, the yield strength of a common tinned copper belt is 95-130 MPa while the yield strength of the extra-soft tinned copper belt processed by the invention is 60-75 MPa, so that the fragment rate during welding is effectively reduced, the welding efficiency is improved and the welding difficulty is lowered.
Description
Technical field
The present invention relates to the processing method that a kind of solar cell connects copper strips, the processing method of the zinc-plated copper strips of particularly a kind of used for solar batteries dead-soft.
Background technology
Solar radiant energy is an important energy, is the energy inexhaustible, nexhaustible, pollution-free, cheap, that the mankind can freely utilize.Improvement along with the solar cell manufacturing technology; Human to environment protection and to the great demand of regeneration clean energy resource; Solar cell will be to utilize the more practicable method of solar radiant energy, can be to utilize solar energy to open vast vistas on a large scale human future.General electric current of monomer solar cell and voltage are all very little, need earlier each monomer solar cell series connection to be obtained high voltage, and parallel connection obtains high electric current again.
At present; Connect the monomer solar cell and mostly adopt the tin-coated copper lead; The tin-coated copper lead is exactly zinc-plated copper strips; Be one of key component in the welding procedure of photovoltaic industry solar battery group, most important for the energy efficiency and the useful life of solar cell, therefore very high to the quality and the performance requirement of zinc-plated copper strips.
More and more moving to maturity is with popular along with the photovoltaic product, and the cost of electricity-generating of assembly also requires more and more lower, and the thickness of battery sheet is also more and more thinner.The thickness of battery sheet from before 0.22mm develop into present 0.2mm, 0.18mm.Though assembly manufacturer can reduce the cost of assembly after the attenuation of battery sheet, the fragment rate that welds the battery sheet but can increase thereupon, if fragment rate increases one thousandth, the assembly of then being 1MW needs how broken 180 battery sheet.
Summary of the invention
The processing method that the object of the present invention is to provide a kind of fragment rate, raising welding efficiency, reduction that can reduce when welding the zinc-plated copper strips of used for solar batteries dead-soft of difficulty.
The technical scheme that realizes the object of the invention is: the processing method of the zinc-plated copper strips of a kind of used for solar batteries dead-soft, adopt the following step:
A) buy hard attitude copper coin band from market;
B) cut;
C) continuous bright annealing;
D) clean;
E) zinc-plated;
F) QC inspection;
G) cleaning tin band;
H) packing of weighing.
The zinc-plated copper strips coefficient of stiffiness that the processing method of the zinc-plated copper strips of above-mentioned used for solar batteries dead-soft is produced is 60Mpa～75Mpa.
The present invention has following characteristics: zinc-plated copper strips of dead-soft and the maximum difference of common zinc-plated copper strips of adopting the present invention to process are that hardness, the tensile strength of base material are essentially different at these 2.The common hardness that is coated with the tin copper strips has only 50 degree, and after the itemize rolling, the external force in the process makes the hardness of copper strips that very big variation take place, and zinc-plated exactly preceding hardness has been increased between the general 53-54.And the zinc-plated copper strips of dead-soft is the operation of first itemize after-baking; Guaranteed the pliability of zinc-plated copper strips finished product like this; The yield strength of common zinc-plated copper strips has between the 95Mpa-130Mpa simultaneously; The yield strength of the zinc-plated copper strips of dead-soft that employing the present invention processes is 60Mpa～75Mpa, the fragment rate when effectively reducing welding, raising welding efficiency, reduction welding difficulty.
Embodiment
(embodiment 1)
The processing method of the zinc-plated copper strips of a kind of used for solar batteries dead-soft, adopt the following step:
A) buy hard attitude copper coin band from market;
B) cut;
C) continuous bright annealing;
D) clean;
E) zinc-plated;
F) QC inspection;
G) cleaning tin band;
H) packing of weighing.
We do following performance requirement regulation to be coated with the tin copper strips for dead-soft: we do following performance requirement regulation the tin copper strips:
Being coated with the tin copper strips with the dead-soft of 0.2 * 1.8 * 230 specifications below is example, illustrates further:
(width tolerance is ± 0.01mm) hard attitude copper material from copper strips manufacturer buying 0.15 (thickness deviation is 0+0.005mm) * 43.8; After the copper strips process Incoming Quality Control that the buying supplied materials is returned is qualified; Get into workshop; At first cut, cut the roller shear cutting apparatus that then adopts roller shear cutting apparatus and 1.8mm; Cut the copper strips that after finishing 24 branches is cut and anneal, annealing operation adopts bright continuous annealing furnace to carry out continuous bright annealing; Copper strips after the annealing must pass through strict cleaning, cleans the zinc-plated effect of back enhanced surface, and cleaned copper strips is at once zinc-plated.Zinc-plated finishing after after the assay was approved packed after the cut-to-length.
The zinc-plated copper strips of common 0.15 * 1.8 * 230 specifications and the dead-soft of 0.2 * 1.8 * 230 specifications are coated with tin copper, and two kinds of zinc-plated copper strips are through having carried out data relatively after the welding of 1Mw:
Above-described specific embodiment; The object of the invention, technical scheme and beneficial effect have been carried out further explain, and institute it should be understood that the above is merely specific embodiment of the present invention; Be not limited to the present invention; All within spirit of the present invention and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
