Description
Technical field
The present invention relates to photovoltaic module preparation field, be specifically related to a kind of typesetting fixing means of flexible solar battery sheet.
Background technology
In order to obtain the required electric property of solar cell and to guarantee its useful life, need to, by solar cell by encapsulation and outside connection, be made into minimum generator unit---photovoltaic module by laminating machine.And make in process of typeset at solar components, solar cell need to be fixed on backboard, cause short circuit in order to prevent that cell piece is in contact with one another simultaneously, guarantee that battery distance remains on 2-3mm left and right., in general flexible thin-film solar establishment of component process, be now all by high temperature gummed tape, cell piece to be fixed on EVA encapsulating film, then by being fixed on (as shown in Figure 1) on backboard after laminating machine hot pressing.Patent 201320515776.8 discloses a kind of solar module with adhesive tape.
Cause short circuit in order to prevent that cell piece is in contact with one another, guarantee that solar components has certain aesthetic property simultaneously, solar battery sheet evenly need to be put and is fixed on backboard, and by high temperature gummed tape, cell piece is fixed on EVA packaging adhesive film, there are following 2 distinct disadvantage: first adopt high temperature gummed tape self-contained battery sheet, understand the sensitive surface that some high temperature gummed tape covers solar cell, even and the very high high temperature gummed tape of transmitance, also can to a certain degree absorb solar light, thereby reduce the irradiance that enters solar battery sheet, affect the generating efficiency of solar cell, secondly, for the fixing high temperature gummed tape of solar cell sensitive surface, need to satisfiedly see through characteristic higher, that viscosity is strong and thickness can not be too thick, and meet the high temperature gummed tape of these characteristics, price is all higher, therefore cause establishment of component cost to increase.
Summary of the invention
For the problems of the prior art, the present invention is on the basis of existing general photovoltaic fexible film assembly encapsulation structure (referring to Fig. 1), utilize EVA packaging adhesive film inviscid at normal temperatures, there is above certain viscosity and be heated to 70-80 DEG C, can fusing be bonded in the characteristic on the object contacting with it, by electric iron, spot welding realizes cell piece and is fixed to the operation on backboard simultaneously.
A kind of typesetting fixing means of flexible solar battery sheet, comprise the steps such as backboard laying, bottom EVA laying, cell piece laying, after by cell piece, laying order is laid on bottom EVA routinely, increase electric iron spot welding heating steps, the method of operation of this step is: at cell piece edge, evenly spot welding one is enclosed in the same direction, afterwards under cell piece center spot welding 2-3.For preventing that cell piece is scalded and damaged cell piece performance and destroy cell piece cosmetic look, position pad one fritter polytetrafluoroethylene high temperature cloth that will spot welding on cell piece.Under normal circumstances, the heating-up temperature of electric iron is within the scope of 100-350 DEG C.
The present invention is by electric iron spot welding heating EVA glued membrane, can make cell piece be fixed on backboard, use the method for high temperature gummed tape self-contained battery sheet with respect to tradition, the present invention has saved assembly production cost, reduce because adhesive tape bonding problem causes after lamination the bad order problems such as assembly bubble, improved production efficiency simultaneously.

Embodiment
Describe the present invention in detail below in conjunction with embodiment and accompanying drawing, but the present invention is not limited to this.
On the basis of existing general photovoltaic fexible film assembly encapsulation structure (referring to Fig. 1), utilize EVA packaging adhesive film inviscid at normal temperatures, there is above certain viscosity and be heated to 70-80 DEG C, can fusing be bonded in the characteristic on the object contacting with it, by electric iron, spot welding realizes cell piece and is fixed to the operation on backboard simultaneously.
As shown in Figure 2, laying order is carried out the steps such as backboard laying, bottom EVA laying, cell piece laying routinely, after cell piece is laid on bottom EVA, increase electric iron spot welding heating steps, with electric iron at cell piece edge in the same direction evenly spot welding one enclose, afterwards under cell piece center spot welding 2-3.
By electric iron, spot welding realizes cell piece and is fixed on backboard, complete in the process of assembly typesetting welding, because the temperature of electric iron is 100-350 DEG C, so heating EVA glued membrane by electric iron, thereby while making EVA glued membrane heating generation viscosity that cell piece is fixed on backboard, in order to prevent that cell piece is scalded and damaged cell piece performance and destroy cell piece cosmetic look, position pad one fritter polytetrafluoroethylene high temperature cloth (referring to Fig. 2) that will spot welding on cell piece.Be heated evenly in order to ensure cell piece simultaneously, prevent cell piece perk, need be with electric iron in the same direction along cell piece edge even spot welding one enclose, finally also need be under cell piece center electric welding 2-3, as shown in Figure 3.
The present invention is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present invention modifications and changes more of the present invention.
