In a second aspect, referring to fig. 1, the present application discloses a laminator vacuum breaking method for a flexible photovoltaic module, wherein at the end of laminating the flexible photovoltaic module 11, a vacuum breaking gas with a temperature higher than a first temperature is introduced into a laminating cavity 3 of the laminator 1 to reduce the difference between the surface temperatures of the upper and lower surfaces of the flexible photovoltaic module 11 until the vacuum breaking of the laminating cavity 3 is completed.

According to one embodiment of the invention, the temperature of the breaching gas is from 50 to 150 c,
specifically, since the types of the packaging materials of the flexible photovoltaic module 11 are more, and the shrinkage rates of the packaging materials are different from each other with respect to the temperature change, the temperature of the heated gas is different from each other with respect to the selection and assembly of different packaging materials, for example, when the difference between the shrinkage rate of the upper surface and the shrinkage rate of the lower surface of the flexible photovoltaic module 11 is not large, and the shrinkage rate is also not changed greatly with the change of the temperature, at this time, the heated gas with a lower temperature is used for performing the breaking process, for example: the temperature is 50 ℃, so that the flexible photovoltaic module 11 can be prevented from deforming;
and when the upper surface shrinkage factor of flexible photovoltaic module 11 is more sensitive to temperature, along with temperature change, the shrinkage factor of the upper surface of flexible photovoltaic module 11 is greater than the shrinkage factor of the lower surface to form defects such as fold on the surface of flexible photovoltaic module 11, so at this moment, need adopt the heated gas of higher temperature to break empty and handle, for example: 150 ℃, thereby avoiding the influence of the overlarge temperature difference between the upper surface and the lower surface on the flatness of the flexible photovoltaic module 11.
And as the flexible photovoltaic module 11 is developed towards the direction of thinning and lightening, the thickness of the packaging material is required to be smaller and smaller, but the thinner material is more and more likely to have a larger shrinkage rate, taking POE plastic as an example, when the thickness is 400um, the shrinkage rate perpendicular to the stretching direction (TD) is about 3%, the broken air with a lower temperature can be selected for performing the breaking treatment, for example, 50 ℃, so as to avoid the situation that the surface of the flexible photovoltaic module 11 is not flat, and when the thickness is 200um, the shrinkage rate perpendicular to the stretching direction (TD) is about 10%, the two groups of situations are compared, the thickness of the packaging material is reduced, but at the same time, the shrinkage rate perpendicular to the stretching direction (TD) is correspondingly increased, at this time, the broken air with a higher temperature can be selected for performing the breaking treatment, for example: at 150 ℃.
Preferably, adopt ethylene-vinyl acetate copolymer (EVA) to encapsulating material, POE plastics, when thickness is 200um, the processing of selecting for use to be broken the sky by the broken empty gas temperature for 95 ℃ is most suitable, can effectively reduce the difference in temperature of flexible photovoltaic module 11 upper and lower surface, and the shrink rate of avoiding between the upper and lower surface material is different, improves flexible photovoltaic module 11's roughness.
In practice, the temperature of the breaching gas can be determined empirically and experimentally by those skilled in the art.
The working process of the present invention is explained below:
open second control valve 10, compressed air source will get into in surge tank 7 through air supply connecting pipe 8, get into in the air supply pipe 4 via the output of surge tank 7 after the steady voltage, the air is set up heating element 5 in the air supply pipe 4 and is heated, observe the temperature variation of air in the air supply pipe 4 in real time through thermoscope 6, when the temperature rose to 50 ℃, open first control valve 9, fill hot-air into lamination chamber 3, through observing the gas volume parameter that shows on the flowmeter, thereby the control gets into the gas in the air supply pipe 4, the atmospheric pressure chamber 3 is broken empty and is handled.
