Description
Technical field
The present invention relates to a kind of improvement of double glass laminating technologies, specifically a kind of method for reducing solar double-glass assemblies air bubble problem
And laminar structure.
Background technology
Solar cell solar double-glass assemblies are laid according to the order of glass+glued membrane+battery strings+glued membrane+glass.Double glass groups
Part uses glass due to two-sided, can design different battery strings arrangement modes, component is saturating according to requirement of the use environment to daylighting
Light rate can be 10%, 40% etc. adjustable.Double glass main flow production technologies are lamination one-shot forming, lamination+autoclave at present, by taking out very
Empty and pressurization mode, carries out component exhaust, bonding, forms finished product.This method is arranged component by extruding exhaust apparatus
Gas, gap of the glass edge away from battery strings, and the space between battery strings, easy residual gas, influence yield rate.
China authorizes the U of utility model patent CN 206040669 to disclose a kind of reduction photovoltaic double-glass assembly edge bubble
Device, including upper strata glass, upper strata glued membrane, glued membrane filler strip, lower floor's glued membrane, lower floor's glass；The upper strata glued membrane is arranged on
Below layer glass, lower floor's glued membrane is arranged on above lower floor's glass, and workpiece area, the glue are provided between upper strata glued membrane and lower floor's glued membrane
The quantity of film filler strip is two, and glued membrane filler strip is arranged on the both sides in workpiece area, and the utility model is filled by increasing glued membrane filler strip
Double glazing gap, increase pressure, improve glued membrane and glassy bond, can solve photovoltaic double-glass assembly edge bubble to a certain extent
Problem, the reliability of product is added, be applicable the photovoltaic double-glass assembly of different templates, different-thickness.
But individual layer filler strip can not effectively reduce unnatural proportions, and meeting after busbar, cell piece change in size is not considered
The follow-up air bubble problem triggered, pad double-deck filler strip position and stagger placements, various busbars, the change of battery chip size can be successfully managed
Change.Had no in above-mentioned patent and mode is effectively improved, it is necessary to supplement perfect to corner location bubble.
The content of the invention
The present invention proposes a kind of method for reducing solar double-glass assemblies air bubble problem for problem present in background technology.
Technical scheme：The grammes per square metre of increase by three position POE glued membranes of solar double-glass assemblies before lamination：Head busbar position, two
Corner is along glass edge position, afterbody busbar position.
As a kind of method of increase POE glued membrane grammes per square metres：Pass through the small bar realities of cushioning a layers POE under the busbar position of head
Now increase the grammes per square metre of head busbar position POE glued membranes；By respectively adding b under cell piece of two corners along glass edge position
Layer POE pads realize grammes per square metre of two corners of increase along glass edge position POE glued membranes；By adding under afterbody busbar position
Pad the grammes per square metre that the small bars of c layers POE realize increase afterbody busbar position glued membrane.
Specifically, the size of the small bars of POE is 100*992mm；The size of the POE pads is 100*100mm.
Specifically, the a=1, b=1, c=2.
Preferably, basic performance is determined according to POE curing curve, draws preliminary parameters, in conjunction with practical effect
Persistently improve parameter, sum up a set of exception and the extremely low laminating parameters of ratio occur.
As a kind of preferred embodiment, last laminating parameters are：150 DEG C of temperature, vacuumizes 360s, and moulding pressure-
15kpa, lamination times 1080s.
Preferably, high temperature cloth, laminating machine rubber, bottom plate smooth foreign are kept during lamination.
Preferably, during lamination by visual observation or the mode of perching knife or a combination of both checks high temperature cloth, rubber, different on bottom plate
Thing is simultaneously changed in time.
Preferably, need to change in time after high temperature cloth fold.
The invention also discloses a kind of laminar structure for reducing solar double-glass assemblies air bubble problem, add under the busbar position of head
Pad the small bars of a layers POE；Respectively add b layer POE pads under cell piece of two corners along glass edge position；In afterbody busbar position
Put the small bars of lower cushioning c layers POE.
Preferably, a=1, b=1, c=2.
Beneficial effects of the present invention
Increase POE glued membrane grammes per square metres in specific position, as concrete implementation method：Increase the POE numbers of plies, make structure special
Position POE loadings are enough, it is ensured that are not in the abnormal caused bubble of filling；Selected as specific specific position：In group
The number of plies for suitably increasing POE with corner location end to end of part, ensure the loading of POE between layer glass after being laminated.
Basic performance is determined according to POE curing curve, summing up a set of exception in conjunction with practical effect ratio occurs
The extremely low laminating parameters of example.
Laminating machine is by visual observation or perching knife inspection ensures that rubber, bottom plate morning foreign matter are cleaned out in time, high temperature cloth fold
After need to change in time because unbalance stress when above mentioned problem can cause the solar double-glass assemblies to be laminated, so as to cause gas not arrange
Go out to form bubble.
