Description
Technical field
The present invention relates to a kind of heat storing type energy-saving heating systems, further relate to the photovoltaic using the heat storing type energy-saving heating system
Component lamination equipment.
Background technique
In the laminating process for preparing photovoltaic module, photovoltaic module is by crystal-silicon battery slice, tempered glass and encapsulating material
(EVA) it after being laminated in a different order, is laminated to form finished product by laminating apparatus.Existing laminating apparatus generally comprises control
System, liftable upper chamber, workbench (including lower room, the loading bay plugged into lower room and discharging platform), heating system, vacuum system
System and pneumatic system.The course of work of laminating apparatus is as follows: laminating apparatus is heated to certain temperature, the photovoltaic module that will be laminated
It is placed on loading bay and send to workbench, control upper chamber decline, vacuumizing by vacuum system will be in each layer of photovoltaic module
Air extraction, in vacuum, EVA starts to melt, and when abstraction is clean completely for air, component internal leaves many skies
Hole；Inflate laminating apparatus upper chamber by pneumatic system, into lamination stages, as pressure increases, cavity is gradually filled out by EVA
It is full；After pressure is stablized, into cross-linking stage, the degree of cross linking of EVA is gradually increased；Reach after a certain period of time, lamination process finishes, layer
Pressure equipment is deflated, promotion upper chamber, on inlet assembly to discharging platform.Laminating technology is the key link of photovoltaic module production, lamination
Temperature corresponds to the solidification temperature of EVA.
Shown in fig. 1 is the workbench 1 of existing laminating apparatus and heating system (including the interior oil circuit for having conduction oil A to flow
3, circulating pump 5 and heat source 8, heat source 8 are electric heater unit), photovoltaic module 2 is placed on workbench 1, is set in the table top of workbench 1
