Concatenation --- --- --- --- --- pack Welding junction box rim frame for lamination for laying by module testing --- appearance test ---
Storage.Wherein, refer to when laying main and glass, EVA, battery, backboard lamination are set, lamination glass successively from bottom to top when usual
Glass, first layer EVA, battery, second layer EVA and backboard.Lamination then refers to all parts for laying completion using hot press
Hot binding forms an entirety, specifically under certain vacuum, at certain temperature, makes the first layer in laminated construction
EVA and second layer EVA are heated and solidified so that each functional layer for forming solar module good is combined together.
Because in the process of lamination, first layer EVA and second layer EVA first heat resolidification, therefore in the process of laying
In, first layer EVA and the second layer EVA surrounding are required for the surrounding beyond glass.In current laying process, first layer EVA
Exceed 3~5mm of surrounding of glass with second layer EVA surrounding, and surrounding is in symmetrically to lay.This laying first layer
EVA and second layer EVA are primarily present following two problems：(1) first layer EVA and the second layer EVA area are all larger, and EVA is used
Measure it is more, cause production cost increase；(2) after lamination process is carried out, EVA residuals are more on laminating apparatus, cause to set
Standby loss increase.
The content of the invention
In view of this, the invention provides a kind of packaging technology of solar cell module, by packaging technology
Laying process is improved, and can effectively reduce the dosage of EVA in solar components production process, reduces production cost and product

To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawings to the specific reality of the present invention
The mode of applying is described in detail.The example of these preferred embodiments is illustrated in the accompanying drawings.Shown in accompanying drawing and according to
What the embodiments of the present invention of accompanying drawing description were merely exemplary, and the present invention is not limited to these embodiments.
Here, it should also be noted that, in order to avoid having obscured the present invention because of unnecessary details, in the accompanying drawings only
Show and according to the solution of the present invention closely related structure and/or processing step, and eliminate little with relation of the present invention
Other details.
In the method for packing of solar cell module provided in an embodiment of the present invention, comprise the following steps：
S1, cell inspection, to reach the purpose of burst：
Due to the randomness of cell piece manufacturing conditions, the battery performance produced is not quite similar, so in order to effective
By performance is consistent or similar battery combination together, so should be classified according to its performance parameter；Battery testing passes through
The size for testing the output parameter (electric current and voltage) of battery is classified to it, to improve the utilization rate of battery, does mass
Qualified battery component.
S2, front welding：
Convergent belt is welded in the main gate line of battery front side (negative pole), convergent belt is tin plating copper strips, the welding having more
It is connected when overleaf welding with the backplate of cell piece below.
S3, back serial connection：
Back side welding is that multi-disc battery is serially connected to form a component string, and operator uses electric iron and solder stick
The front electrode (negative pole) of " forward battery " is welded in the backplate (positive pole) of " rear battery ", so successively by multi-disc
It is serially connected and welds out lead in the both positive and negative polarity of component string, forms cell panel.
S4, laying process (also referred to as lamination procedure)：
Back serial connection is good and passes through after the assay was approved, by the EVA of cell panel, glass plate and well cutting, backboard according to certain
Level lay, prepare lamination.
As shown in figure 1, the level of laying is followed successively by from bottom to top：Glass plate 1, the first EVA layer 2, cell panel 3, the 2nd EVA
Layer 4 and backboard 5.

Value d1, and in the glass plate 1 and the first side 1a the 3rd relative side 1c and the fourth side 1d relative with the second side 1b, it is described
Width of the edge of first EVA layer 2 beyond the edge of the glass plate 1 is second value d2, wherein the first numerical value d1 is small
In the second value d2, the surrounding edge of second value d2 value and EVA layer in the prior art exceeds the edge of glass plate
Width it is suitable.Further, the laying of the second EVA layer 4 is then complementary with the laying of the first EVA layer 2 dislocation, as shown in figure 3,
In the first side 1a and the second side 1b adjacent with the first side 1a of the glass plate 1, the edge of second EVA layer 4 exceeds institute
The width for stating the edge of glass plate 1 is second value d2, and the glass plate 1 the threeth side 1c relative with the first side 1a and
The fourth side 1d relative with the second side 1b, the width of the edge of second EVA layer 4 beyond the edge of the glass plate 1 is the
One numerical value d1.
System of laying based on more than, because second value d2 is suitable with existing numerical value, the first numerical value d1 is less than second
Numerical value d2, although single EVA layer (the first EVA layer 2 or the second EVA layer 4) area reduces, the first EVA layer 2 and the 2nd EVA
Layer 4 is the complementary position relationship that stacks and misplace, and it is still able to the encapsulation requirement for meeting component；And due to the He of the first EVA layer 2
Second EVA layer 4 can reduce width of the both sides therein beyond the edge of glass plate 1 respectively, can effectively reduce solar energy group
EVA dosage in part production process, production cost and unit consumption of product are reduced, and solar components production lamination can also be reduced
During, residuals of the EVA in laminating machine, reduce equipment loss.
In preferable technical scheme, the first numerical value d1 is smaller 1~3mm than the second value d2.Specific to this implementation
In example, the first numerical value d1 selections are between 1~2mm, and the second value d2 selections are between 3~4mm.
S5, lamination：
The battery laid is put into laminating machine, extracted out the air in component by vacuumizing, then heating makes EVA
Fusing bonds together battery, glass and backboard, and component is taken out in finally cooling.
S6, rim frame：
Similar to filling a picture frame to glass；Aluminium frame is filled to glass assembly, increases the intensity of component, further sealing electricity
Pond component, extend the service life of battery.
S7, Welding junction box：
A box is welded at module backside lead, in favor of the connection between battery and other equipment or battery.
S8, module testing：
The purpose of test is that the parameters such as the power output of battery are demarcated, and tests its output characteristics, determines component
Credit rating.
