Description
Technical field
The present invention relates to solar cell module technical fields, align installation side more particularly to a kind of battery strings welding
Method.
Background technique
Several monomer solar battery sheets are packaged into solar battery group after series, parallel connects, using tight
Power supply could be used as to use after part.Battery front side electrode is formed using the thin grid line of screen printing technique printing silver and main gate line
, grid line is the important component of cell piece, it is responsible for the intracorporal photogenerated current of battery to guide to outside batteries, general specific
Refer to thick electrode (main grid line electrode) item number on cell piece surface.Cell backside electrode is the another side opposite with front electrode
Electrode can be used slurry and print rectangular or other shapes.
More main grids (Multi-Busbar, MBB) are often referred to main gate line at 10 or more, can not only reduce cell piece
Surface is blocked, and light-receiving area is increased, and reduces the distance that electric current passes through in thin grid, the series electrical of component can also be effectively reduced
Resistance reduces the electric current of every main grid carrying, and resistance loss is smaller, and transfer efficiency is higher.But due to used when MBB series welding section for
Circular tinned wird is as welding, and contraposition difficulty is big when comparing the welding of traditional squashed structure, to the more demanding of welding equipment,
And welding fastness is difficult to ensure, influences production efficiency and product quality.
Summary of the invention
In view of the above technical problems, the present invention provides a kind of battery strings welding align installation method, the pickup of welding and
Positioning is convenient, and is not susceptible to situations such as shifting or misplacing, and welding installation effectiveness is high, further improves the production efficiency of component
And product yield, and can be used in more main grid technologies and dereliction gate technique.
To realize the above-mentioned technical purpose, present invention employs following technical solutions:
Step a, it uses section for circular welding, is carried out in the bottom surface of welding front half section and the top surface of welding second half section uniform
Dispensing；
Step b, 1# cell piece is placed on workbench, the welding for completing step a is placed on 1# cell piece, welding first half
Section is placed on workbench perpendicular to the thin grid setting of 1# cell piece, welding second half section, is then placed on the welding second half section
2# cell piece；
Step c, circulate operation step a- > step b, completes the placement of all cell pieces and welding.
Preferably, the cell piece uses more main grid cell pieces, the main grid and welding on welding covering 1# cell piece
Quantity is identical as the main grid quantity of 1# cell piece.
Preferably, the cell piece is dereliction grid cell piece.
Preferably, it is the copper wire that surface is coated with SnPb layers that the section, which is circular welding,.
By adopting the above-described technical solution, the present invention has the following technical effect that the present invention uses section to be circular
Welding carries out many places dispensing on welding in advance, is located on the face being bonded with cell piece at dispensing, after welding places, weldering
The pickup and positioning of band are convenient, and are not susceptible to situations such as shifting or misplacing, and welding installation effectiveness is high, further improves component
Production efficiency and product yield.
Detailed description of the invention
Examples of the present invention will be described by way of reference to the accompanying drawings, in which:
Fig. 1 is the structural schematic diagram that the battery strings of interconnection are realized using method of the invention；
1 is cell piece, and 2 be welding, and 3 be dispensing position.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification unless specifically stated can be equivalent or with similar purpose by other
Alternative features are replaced.That is, unless specifically stated, each feature is an example in a series of equivalent or similar characteristics
?.
A kind of battery strings welding as shown in Figure 1 aligns installation method, and several cell pieces of battery strings are formed including interconnecting
1, adjacent cell piece is connected by welding 2.
Specifically, when adjacent cell piece connects, prime cell piece is denoted as 1# cell piece, rear class cell piece is denoted as 2# battery
Piece, including following installation steps:
Step a, it uses section for circular welding, is carried out in the bottom surface of welding front half section and the top surface of welding second half section uniform
Dispensing, dispensing position 3 refer to Fig. 1, and cell piece is more main grid cell pieces, the quantity and the main grid quantity phase of 1# cell piece of welding
Together；Step b, 1# cell piece is placed on workbench, the welding for completing step a is placed on 1# cell piece, welding first half
One main grid of section covering 1# cell piece, welding second half section are placed on workbench, then place 2# on the welding second half section
Cell piece；
Step c, circulate operation step a- > step b, completes the placement of all cell pieces and welding.
In addition, method of the invention is equally applicable to the interconnection of dereliction gate technique (busbar-free) cell piece, that is, work as electricity
When pond piece uses dereliction grid cell piece, welding is a plurality of, dereliction gate technique cancellation perpendicular to the thin grid setting of 1# cell piece, quantity
Traditional main grid, a plurality of welding in dereliction gate technique perpendicular to thin grid can be regarded as instead of conventional batteries on piece main grid
Role, welding is directly connected to the thin grid of cell piece, and battery interconnection is realized while collecting electric current.
Wherein the copper wire that surface is coated with SnPb layers can be used in welding.
