Description
Technical field
The utility model belongs to new forms of energy solar module manufacturing industry, particularly a kind of laminater of flexible solar cell assembly.
Technical background
Solar module generally adopts laminated construction, and the functional layer of its formation is respectively: back-protective material, EVA hot melt solidified glue film, connection in series-parallel stacks of cells, EVA hot melt solidified glue film, front printing opacity protective material.The laminating method of solar module is under certain vacuum, under certain temperature, makes fusion of EVA hot melt solidified glue film and curing in the solar module laminated construction, and each functional layer good binding of feasible formation solar module together.In the lamination process of solar module, the maintenance of certain vacuum has been avoided producing bubble between each functional layer of solar module, and has been had influence on the outward appearance and the life-span of whole solar module.
The laminater of traditional solar module is divided into two vacuum chambers, a heating platform; Separated by silicane rubber plate between the vacuum chamber up and down, following vacuum chamber base plate is a heating platform, and an one of which complete technological is: will descend the vacuum chamber base plate is that heating platform is heated to certain temperature; Last vacuum chamber extracting vacuum is opened down vacuum chamber, and the solar module with laminated construction of treating lamination is put into down vacuum chamber; Close down vacuum chamber; To following vacuum chamber extracting vacuum, when treating down that vacuum chamber reaches the certain vacuum condition, upwards vacuum chamber charges into atmosphere; Silicane rubber plate between the vacuum chamber is under the effect of vacuum chamber pressure difference up and down so up and down, and the base plate that can be pressed onto down vacuum chamber is on the heating platform.In this process, the bubble that has between each functional layer of solar module of laminated construction is excluded, and via the curing of EVA hot melt solidified glue film, have laminated construction solar module each functional layer good binding together.

1) the vacuum chamber base plate is both on the heating platform under from following vacuum chamber extracting vacuum to being pressed in that the silicon rubber version the vacuum chamber is complete up and down; Because will be with descending the air in the vacuum chamber to empty to certain state; According to the difference of process conditions, generally preset 2 minutes to 20 minutes following vacuum chamber pumpdown time, in this time period; Following vacuum chamber keeps the state of a cavity, and promptly silicane rubber plate and the following vacuum chamber base plate between the vacuum chamber is to have certain clearance between the heating platform up and down.Because the existence in this gap; The solar battery cell of flexible substrates, and/or flexible encapsulating material, meeting is owing to shrinkage factor in the EVA hot melt solidified glue film melting process is inhomogeneous; And produce the fold phenomenon, and then can have influence on the outward appearance and the life-span of the solar module of lamination completion.
2) in the lamination process, following vacuum chamber has violent airflow fluctuation at the extracting vacuum initial stage.The fluctuation of this air-flow, to rigid basement, and/or the influence of the solar module of rigidity encapsulating material is limited, but for flexible substrates, and/or the influence of the solar module of flexible encapsulant material is bigger.Flexible substrates, and/or the solar module of flexible encapsulant material can produce the fold phenomenon, and then can have influence on the outward appearance and the life-span of the solar module of lamination completion under the fluctuation of this air-flow.
3) in the lamination process, in the inflation of last vacuum chamber, the silicane rubber plate between the vacuum chamber is under the pressure differential effect between the vacuum chamber up and down up and down; Press to down in the process that the vacuum chamber base plate is a heating platform; Because the inhomogeneities of silicane rubber plate under heat expands state can have influence on the flexible substrates of treating lamination with this inhomogeneous state, and/or on the solar module of flexible encapsulant material; And produce the fold phenomenon, and then can have influence on the outward appearance and the life-span of the solar module of lamination completion.
