Abstract
The utility model provides a kind of solar cell backboard opening, and the back plate openings are located at the centre of backboard, and the back plate openings both ends is semicircle, width 2mm；The length of the back plate openings is determined according to the model of solar panel；The back plate openings and the spacing of back plate edges are determined according to the model of solar panel；Advantage is：The cambered design at back plate openings both ends, effectively avoids backboard tear；The increase of width, it is therefore prevented that EVA overflows after melting, and enhances product performance.
Description
Technical field
Battery manufacturing field is the utility model is related to, more particularly, to a kind of solar cell backboard opening.
Background technology
Positive energy battery component refers to have outer enclosure and the internal minimum for connecting, direct current electricity output being provided separately can not
The solar battery group of segmentation, which attaches together, puts, it is made of solar battery sheet, tempered glass, EVA, backboard and aluminium frame, tool
There is service life length, the features such as mechanical resistance to compression external force is strong.
The production method of solar cell module, comprises the following steps：Sorting；Welding；Laminated laying；Component lamination；Go
Side；Frame up；Welding junction box；Test；Packing.Wherein laminated laying：By glass, EVA, component string, EVA and backboard according under
Upward level is laid.In whole manufacturing process, laminated laying is most important step, directly influences the matter of battery component
Amount.
During traditional laminated laying, the opening of backboard is yi word pattern opening, and width is only 1mm, is laid entirely
Cheng Zhong, backboard be easy to tear, serious waste back veneer material；In lamination process, EVA melts, since yi word pattern opening is wide
Spend too narrow, EVA spillovers are serious, pollute laminating machine and solar cell module, seriously affect the quality of battery component.
The content of the invention
The purpose of this utility model is that to solve the deficiencies in the prior art, and a kind of solar cell backboard is provided and is opened
Mouthful.
The new technical solution of the utility model is：A kind of solar cell backboard opening, the back plate openings are positioned at the back of the body
The centre of plate, the back plate openings both ends is semicircle, width 2mm；The length of the back plate openings is according to solar energy
The model of solar panel determines.
The back plate openings and the spacing of back plate edges are determined according to the model of solar panel.
The beneficial effects of the utility model are：The cambered design at back plate openings both ends, effectively avoids backboard tear；It is wide
The increase of degree, it is therefore prevented that EVA overflows after melting, and enhances product performance.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Wherein：1 is back plate openings, and 2 be backboard.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
A kind of solar cell backboard opening, the back plate openings 1 are located at the centre of backboard, the back plate openings 1
Both ends is semicircle, width 2mm；The length of the back plate openings 1 is determined according to the model of solar panel.
The spacing of the back plate openings 1 and 2 edge of backboard is determined according to the model of solar panel.
Claims (2)
