2) pumpdown time of upper chamber is set to 310 ± 20s, and the pumpdown time of lower room is set to 300 ± 20s,
3) pressurize for the first time, upper chamber pressure set is -70 ± 5kPa, and keep 5 ± 2s, meanwhile, lower room keeps vacuumizing
State；
4) second of pressurization, upper chamber pressure set is -60 ± 5kPa, and keeps 5 ± 2s, meanwhile, lower room keeps vacuumizing
State；
5) it is laminated, upper chamber pressure set is 0kPa, and keeps 540 ± 50s, meanwhile, lower room keeps vacuumizing state；Lamination
Temperature is set as 142 ± 5 DEG C；
6) room continuation holding is vacuumized under, and set of time is 20 ± 5s；
7) room is inflated under, and the time is set as 50 ± 5s；
After above-mentioned steps, that is, obtain the solar panel.
The solar panel now obtained is not punch the component with trimming, in order that product is convenient for carrying and more
Plus it is attractive in appearance, the solar panel can be put into default laser cutting machine and be cut, ensure not damage battery during cutting
Piece 31 and the mutual latticing., can be with as shown in Fig. 2 mounting hole 120 can be cut out in four corners of the solar panel
Lanyard is worn on mounting hole 120, to facilitate the hook of solar panel；And it is possible in the first cell piece group and second
Modification hole 130 is set between in cell piece group, to facilitate the folding of product, also make it that product is more attractive in appearance.
The preparation technology for the solar panel that the embodiment of the present invention is provided, the design parameter of each step is
Drawn by repeated tests, the shaping to product is most important.It is divided into pressurization for the first time for example, pressurizeing and adds for the second time
Pressure, and pressurization twice and lamination are provided with different pressure, pressure mainly have impact on the conjugation of multilayer material, and different
Pressure values must in sequence, and otherwise a problem that forming bad bubble, feel, uneven surface occurs in product.And in layer
Journey is pressed through, temperature is set as 142 ± 5 DEG C, and temperature is too high, can cause the damage of integral material, and temperature is too low, can cause multilayer material
The conjugation of material is inadequate.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection domain of the claims in the present invention
Within.
