Specific implementation mode

As depicted in figs. 1 and 2, the utility model is designed to assist solar cell module to assemble, it is therefore an objective to In order to reach the reduction of EVA glue overflow amounts.

By taking battery strings is the components of 6*10 as an example, glass common-use size used（Long * wide）For 1634 × 986mm, EVA used Also there are corresponding size, but slightly difference.EVA is generally packaged material, and width is fixed（974mm, company are general）, long Degree is 500m, and each company can cut the EVA of required length according to actual demand.It takes measures in terms of following three：

Laterally：

Glass width is 986mm, and EVA width is 974mm, and EVA width is narrower than glass, and how is battery strings upper layer and lower layer EVA It is laid with, is directly related to the excessive glue situation of EVA.Attemptable direction includes：It is placed in the middle simultaneously at the same by one side, be dislocated Three kinds of directions.When placed in the middle simultaneously, the right and left EVA is away from glass edge 6mm；When simultaneously by one side, another side EVA is away from glass edge 12mm；Through attempting, both extreme modes, can due to EVA away from glass edge too far, cause seam crossing starved, peeling force it is insufficient, Phenomena such as backboard is layered.Therefore, it is dislocated laying, becomes the direction for continuing deeper into investigation.

EVA is away from glass edge：

When 1mm, excessive glue situation is serious.EVA, which overflows glue, very strong viscosity, and when high temperature can be sticked to module edge, or even anti- Adhere to glass front, it is difficult to clear up.

When 2.5mm, excessive glue significantly reduces, basic viscous less than face glass paper/high temperature cloth；

When 3.5mm, there is a small amount of spilling glue, but exist only in the seam crossing of glass and backboard, do not overflow glass surface；

When 4.5mm, invisible spilling glue, but this kind of situation easily causes seam crossing starved, and podoscutum is not layered peeling force.

It is longitudinal：

According to conclusions, when EVA is away from glass edge 3mm, glue overflow amount control is preferable.On the basis of glass length 1634mm On, cut EVA length is advisable for 1627.5 ~ 1628.5mm.

Excessive glue adjusts at head insulation item

Component head is other than 2 layers of EVA, and the also one layer insulation small item of EVA, small general size of EVA is 640*85mm, in Between have 25 ± 1mm slit widths, for being inserted into lead-out wire both ends.The small items of EVA can move up and down, therefore the distance away from head of glass needs It chooses best.The distance of 2 layers of EVA tool head of glass, according to the above experiment, excessive glue control effect is best when 2.5 ~ 3.5mm. The distance of the small item tool head of glass of EVA has to be determined.

Paving location is four pieces of cell pieces among head, and before adjustment, EVA insulated parts are flushed with glass edge, glass edge The accumulative EVA that haves three layers（2 layers of conventional edge）, it is apparent to overflow glue；

After adjustment, conventional EVA is away from 2.5 ~ 3.5mm of glass edge, and the insulation small items of EVA are away from 4.5 ~ 5.5mm of glass edge, it is seen then that EVA When small item is away from 4.5 ~ 5.5mm of glass edge, best excessive glue control effect is had been achieved for.

These sizes can only probably be estimated in production process, and the time can be greatly prolonged if measuring every time, this The frame that utility model is placed on the table by using one, solar components are all assembled in lower portion, group Taking down frame on workbench after the completion of dress can.
