It can be 2kPa -15kPa to enclose.
The step of epicoele 231 boosts can be divided into multiple time phases, wherein first time
The pressure in epicoele 231 is set linearly to rise to the certain value of atmospheric pressure in stage, thereafter multiple
Pressure in time phase, epicoele 231 gradually rises up to atmospheric pressure.When can so allow multiple
Between in the stage rate of rise of epicoele 231 it is different, in several time phases of beginning, 231 liters of epicoele
Press speed slower, several time phases thereafter, the speed that epicoele 231 boosts gradually is accelerated, this
Sample can effectively reduce the time of the boosting of epicoele 231.While in order to place pressure liter in epicoele 231
High excessive velocities, cause solar battery group to be crushed out of shape, and the pressure of epicoele 231 slowly rises
The time of first time phase is no less than 2min.
In the pressurization steps, the internal pressure of cavity of resorption 232, which is tried hard to keep, holds the constant stage, and its pressure can pass through
Micro inflation or micro vacuumize are adjusted, when pressure causes it because of micro-leakage in cavity of resorption 232
Interior pressure rise, then open cavity of resorption vacuum valve 254, reduces the pressure in cavity of resorption 232；Work as cavity of resorption
When pressure is slightly lower than predetermined pressure in 232, then the second gas bleeder valve 259-2 is opened, to cavity of resorption 232

The cavity of resorption charge valve 257 of connection is opened, and air is filled with to cavity of resorption 232, the pressure in cavity of resorption 232
Power is recovered to atmospheric pressure, control system control piston 102, and lid 210 is moved upwards in drive,
Conveyer belt 102 is moved, and the solar cell module that lamination is finished is transported to other stations, is carried out
Next step is processed.
In pressurization steps, pressure release step, when being filled with air in epicoele 231, cavity of resorption 232,
Pressure-bearing heating plate 221 and the temperature of solar cell module are still higher, if the air humidity being filled with
Larger, in pressure release phase, the temperature drop of solar cell module is very fast, in such air
Moisture may solar cell module surface formed water droplet, therefore by epicoele charge valve 247,
Cavity of resorption charge valve 257 is connected with air dryer, air cleaner respectively, so can be more preferable
The solar cell module of protection.
As shown in Fig. 4-Fig. 8, after the completion of pressurization steps, the pressure in epicoele 231 is air
Pressure in pressure, cavity of resorption 232 is still less than atmospheric pressure, in order to effective using in cavity of resorption 232
