Description
Technical field
The utility model is related to field of photovoltaic power generation more particularly to a kind of photovoltaic modulies.
Background technology
Photovoltaic module chief component is followed successively by cover board, upper layer EVA packaging adhesive films, cell piece, lower layer EVA from top to bottom
Packaging adhesive film and backboard, above-mentioned component are being formed as a single piece after laminating machine laminating, and temperature is higher when due to lamination,
And EVA packaging adhesive films have certain mobility, therefore in lamination, EVA packaging adhesive films are easy the surrounding from cover board and backboard
It overflows, the EVA envelopes for be contacted with laminating machine high temperature cloth, causing the cross contamination between high temperature cloth and photovoltaic module, while overflowing
Dress glued membrane be easy to remain in the edge of photovoltaic module so that edge become it is coarse unsightly, usually add in photovoltaic module
It just needs to carry out chamfered edge cleaning treatment before dress metal edge frame, the EVA packaging adhesive films of spilling be removed, this adds increased additional works
When, reduce production efficiency.
Utility model content
In view of this, the utility model provides a kind of photovoltaic module, the problem of packaging adhesive film overflows can be improved.
Specifically, the utility model is achieved by the following technical solution：A kind of photovoltaic module, including from top to bottom according to
The secondary cover board being stacked, upper layer packaging adhesive film, battery strings, lower layer's packaging adhesive film and backboard, in the cover board and backboard at least
The inner surface of one is equipped with excessive glue groove.
Further, the excessive glue groove is distributed along the edge of the cover board or backboard, and apart from the edge
Distance be 1-2mm.
Further, the excessive glue groove is rectangular.
Further, the upper layer packaging adhesive film, lower layer's packaging adhesive film are respectively positioned on the inside region of the excessive glue groove.
Further, the width of the excessive glue groove is 1-2mm, depth 1-2mm.
Further, excessive glue groove is equipped on the inner surface of the backboard and cover board, and the position of excessive glue groove corresponds
Setting.
The utility model on backboard or cover board by opening up excessive glue groove so that packaging adhesive film lamination when overflow outward into
Enter in the excessive glue groove, and is unlikely to overflow the edge more than the backboard or cover board and remains in the edge of photovoltaic module
On, it is therefore prevented that cross contamination handles without additional chamfered edge is carried out to photovoltaic module edge, improves production efficiency.

Specific implementation mode
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the utility model.On the contrary, they be only with such as
The example of the consistent device and method of some aspects be described in detail in the appended claims, the utility model.
It is the purpose only merely for description specific embodiment in the term that the utility model uses, is not intended to be limiting this reality
With novel.In the "an" of the utility model and singulative used in the attached claims, " described " and "the"
It is intended to include most forms, unless context clearly shows that other meanings.It is also understood that term used herein " and/
Or " refer to and include one or more associated list items purposes any or all may combine.
As shown in Figures 1 to 4, the utility model provides a kind of photovoltaic module 100 comprising from top to bottom stacks gradually and sets
Cover board 10, upper layer packaging adhesive film 20, battery strings 30, lower layer's packaging adhesive film 40 and the backboard 50 set, the cover board 10 and backboard 50
Be oppositely arranged, the upper layer packaging adhesive film 20, battery strings 30, lower layer's packaging adhesive film 40 be located in cover board 10 and backboard 50 it
Between, by forming photovoltaic module 100 after lamination.
The backboard 50 is set to bottom, for carrying the cover board 10, upper layer packaging adhesive film 20, battery strings 30 and lower layer's envelope
Glued membrane 40 is filled, ginseng can be coordinated as shown in figure 3, the backboard 50 is rectangular, and inner surface is equipped with the edges excessive glue groove A, the excessive glue groove A
The edge of the backboard 50 extends distribution, and there are a certain distance between edge, preferable in the utility model
In embodiment, distances of the excessive glue groove A apart from the edge of the backboard 50 is 1-2mm, preferably 1.5mm, and excessive glue
The width of slot A itself is 1-2mm, and the depth of excessive glue groove A is 1-2mm, and the excessive glue groove A is rectangular.Fig. 1 and Fig. 2 please be participate in,
Before lamination, lower layer's packaging adhesive film 40 is laid on the inside of excessive glue groove A, and edge does not extend to the excessive glue groove A outside area
Domain, and edge 3mm of the lower layer's packaging adhesive film 40 apart from backboard 50, and after laminating, lower layer's packaging adhesive film 40 is squeezed
And flowed towards 50 edge of backboard, it is limited at this time by the excessive glue groove A of 50 inner surface of backboard, excessive glued membrane is then limited
System is unlikely to the edge for continuing to be spilled over to photovoltaic module 100 outward in excessive glue groove A.
Certainly, it also is provided with excessive glue groove A on the inner surface of the cover board 10, the excessive glue of excessive glue groove A and 50 inner surface of backboard
Slot location A corresponds, as shown in figure 4, preventing excessive glue by the excessive glue groove A collective effects of upper and lower both sides, so that lamination
When can reach better adhesive-spill-preventing effect.
The utility model on backboard 50 or cover board 10 by opening up excessive glue groove A so that packaging adhesive film is outside in lamination
It overflows into the excessive glue groove A, and is unlikely to overflow more than the edge of the backboard 50 or cover board 10 and remain in photovoltaic group
On the edge of part 100, it is therefore prevented that cross contamination is carried out without to 100 edge of photovoltaic module at additional chamfered edge
Reason, improves production efficiency.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent substitution, improvement and etc. done should be included in the utility model
