The EVA film solidification system also comprises a heating system for heating the EVA film and a freezing system for solidification; in the lamination process, the EVA adhesive film is heated to a molten state through a heating system, so that the packaging and bonding of the solar panel are realized, and after the heating and the laminating are completed, the molten EVA adhesive film is cooled through a refrigerating system, so that the EVA adhesive film in the molten state is rapidly solidified.
When in use, the back plate 19, the EVA adhesive film, the battery piece 18, the EVA adhesive film and the toughened glass are sequentially stacked, the telescopic cylinder 3 is extended to the position between the first fixing plate 4 and the second fixing plate 6 through controlling the extension of the telescopic cylinder 3, the first fixing plate 4 is fixedly connected with the second fixing plate 6 through the fixing piece, the clip frame 5 is placed at the center of the through groove of the base 1, the clip frame 5 is fixed below the first fixing plate 4, one end of the high-temperature resistant elastic layer 15 is hermetically fixed in the clip groove 8 through the first clip plate 10 and the second clip plate 11 in the clip grooves 8 at the lower part, namely, the high-temperature resistant elastic layer 15 is tightly pressed and fixed between the first fixing plate 4 and the second fixing plate 6 after passing through the fixing block 9 and the spring through the screws and then being sequentially in threaded connection with the first fixing plate 4 and the second fixing plate 6, then, the stacked solar cell is placed in the center of the through groove of the base 1, the other end of the high-temperature-resistant elastic layer 15 is hermetically fixed in the multiple circular grooves 8 on the top circular frame 5 through the first circular plate 10 and the second circular plate 11 in the multiple circular grooves 8 in the top circular frame 5, namely, the high-temperature-resistant elastic layer 15 is sequentially in threaded connection with the first fixing plate 4 and the second fixing plate 6 in the top circular frame 5 after sequentially penetrating through the fixing block 9 and the spring in the top circular frame 5 through screws, and is tightly pressed and fixed between the first fixing plate 4 and the second fixing plate 6; then, the electric telescopic rod 12 is controlled to extend, the electric telescopic rod 12 extends and pushes the electromagnet to be connected with the screw, and then the electromagnet and the screw are controlled to be powered on to be attracted magnetically; because the high temperature resistant elastic layer 15 has elasticity, the high temperature resistant elastic layer 15 is always in contact with the edge of the solar cell laminated assembly, then the heating is carried out by controlling the heating system, the back plate 19, the EVA adhesive film, the cell piece 18, the EVA adhesive film and the EVA adhesive film in the toughened glass are heated to a molten state, then the top hydraulic telescopic rod 14 and the telescopic cylinder 3 are controlled to synchronously extend, the hydraulic telescopic rod 14 and the telescopic cylinder 3 extend to extrude the solar cell panel about to enter the laminating process, because the laminated solar cell panel is subjected to extrusion force, the EVA adhesive film between the laminated solar cell panels is extruded out from the gap between the back plate 19 and the cell piece 18, and between the cell piece 18 and the glass plate 17, and then flows into the cavity enclosed between the high temperature resistant elastic layer 15 and the solar cell, the glass plate 17 and the second fixing plate 6, in the process of extending and extruding of the hydraulic telescopic rod 14 and the telescopic cylinder 3, meanwhile, according to the liquid pressure in the cavity enclosed between the high temperature resistant elastic layer 15 and the solar cell, the glass plate 17 and the second fixing plate 6 detected by the liquid pressure sensor, adjustment is performed, for example, because the hydraulic telescopic rod 14 and the telescopic cylinder 3 extend synchronously, the return frame 5 moves downwards, the positions of the first return plate 10 and the second return plate 11 do not change, but because the return frame 5 moves downwards, the molten EVA adhesive film between the stacked solar cell panels is extruded more and more from the back plate 19 and the cell sheet 18 and the gap between the cell sheet 18 and the glass plate 17, so that the liquid pressure in the cavity enclosed between the high temperature resistant elastic layer 15 and the solar cell, the glass plate 17 and the second fixing plate 6 is increased, when the liquid pressure sensor detects that the pressure value is greater than the preset value, the electric telescopic rod 12 is controlled to extend until the liquid pressure sensor detects that the pressure value is equal to the preset value, because the electric telescopic rod 12 extends, the spacing distance between the upper first return plate 10 and the lower first return plate 11 and the second return plate 11 is reduced, so that the high-temperature-resistant elastic layer 15 becomes loose from a tensioning state, and further the pressure value detected by the liquid pressure sensor is reduced and is restored to a preset pressure value, on one hand, the height of the overflowed molten EVA adhesive film can be changed along with the change of the lamination gap, on the other hand, the thickness of the overflowed EVA adhesive can be automatically adjusted according to the overflowed adhesive amount under the condition that the overflowed molten EVA adhesive can be ensured to be completely filled in a cavity enclosed between the high-temperature-resistant elastic layer 15 and the solar cell, the glass plate 17 and the second fixing plate 6 all the time, so that the solidification thickness of the EVA adhesive solidified at the edge of the solar cell plate can be adaptively increased, and because the thickness of the EVA adhesive is increased, therefore, the buffering capacity between the solar cell panel and the outer frame of the solar cell panel can be enhanced; in the third aspect, because the opposite ends of the two second fixing plates 6 are both located in the space between the two square-shaped frames 5 and are symmetrically arranged, and meanwhile, the end faces opposite to the two square-shaped frames 5 are not at the same height, that is, as shown in fig. 7, point B, EVA glue can be filled between the square-shaped frames 5 and the glass plate 17 or between the square-shaped frames 5 and the back plate 19, so as to prevent the solar cell panel from directly contacting with the square-shaped frames 5 (the square-shaped frames 5 will be used as a part of the outer frame of the solar cell panel in the back-side packaging), after the outer frame is affected by long-time illumination, because the temperature of the outer frame of the solar cell panel is higher than that of the solar cell panel, if the two are directly assembled, the power generation efficiency of the cell string in which the peripheral edge of the solar cell panel contacts with the outer frame is easily affected by the high temperature of the outer frame, and further, the EVA glue overflowing during the packaging process forms a solidified EVA glue isolating layer between the square-shaped frames 5 and the glass plate 17, therefore, the situation that the high temperature of the outer frame influences the power generation efficiency of the cell string in which the peripheral edge of the solar cell panel is contacted with the outer frame is avoided; in the fourth aspect, the square frame 5 which plays a role in sealing and compressing in the packaging process is used as the outer frame of the solar cell panel, so that the steps of assembling the outer frame are reduced, and the packaging efficiency is improved; when the hydraulic telescopic rod 14 and the telescopic cylinder 3 extend until the pressure value detected by the pressure sensor is equal to the preset value, the molten EVA adhesive is rapidly cooled by starting the cooling system; after cooling, the fixed frame 16 is adsorbed by the sucker, the telescopic part is controlled to extend to push the sucker and the fixed frame 16 to move, the fixed frame 16 is inserted into a gap between the two clip frames 5, and then the fixed frame 5, the stop block 7, the fixed frame 16, the stop block 7 and the clip frames 5 sequentially penetrate through the clip frames 5, the stop block 7 and the clip frames 5 through screws and are finally fixedly connected with the clip frame 5 at the bottommost part through threads; therefore, the installation of the outer frame of the solar cell can be completed, and the installed solar cell panel is moved out of the laminating working area through the mobile equipment.
After the installation of the outer frame of the solar cell is completed, the sealing liquid filling pipe is butted with the sealing liquid filling port, and then the sealing liquid filling pump is controlled to start. Therefore, the sealing liquid filling pump pumps the sealing liquid into a sealing chamber which is surrounded by the high-temperature-resistant elastic layer 15, the square-shaped frame 5, the fixed frame 16 and the stop dog 7 to form a buffer layer, and the sealing liquid buffers the solar power generation panel in the transportation process; thereby, the whole encapsulation of the solar cell panel can be completed.
It should be emphasized that, in the solar cell panel manufactured by the present invention, when the solar cell panel is in high temperature weather, because one end of the screw is fixedly connected with the first return plate 10 and the second return plate 11, and the other end of the screw is slidably connected with the fixing block 9, when the solar cell panel is in high temperature weather, the sealing liquid expands, and the sealing liquid expands to push the first return plate 10 and the second return plate 11 to move outwards together, so that the internal volume of the sealing liquid storage chamber is increased, and the situation that the connection between the fixing frame 16 and the return frame 5 is opened due to the expansion of the sealing liquid caused by over-high temperature is avoided.
The invention also provides a solar cell packaging method, which comprises the following steps:
s1, mounting the clip frames 5 at the top and the bottom of the packaging assembly;
s2, fixing one end of the high-temperature-resistant elastic layer 15 on the lower clip frame 5 through a screw, the first fixing plate 4 and the second fixing plate 6, then placing the overlapped solar cell panel at the center of the lower clip frame 5, and fixing the other end of the high-temperature-resistant elastic layer 15 in the upper clip frame 5;
s3, heating the EVA adhesive film to a molten state by controlling a heating system, synchronously extending the top hydraulic telescopic rod 14 and the telescopic cylinder 3 to a position where a pressure value detected by the pressure sensor is equal to a preset value, and in the synchronous extension process of the hydraulic telescopic rod 14 and the telescopic cylinder 3, when the pressure value detected by the liquid pressure sensor is greater than the preset value, extending the electric telescopic rod 12 to a position where the pressure value detected by the liquid pressure sensor is equal to the preset value and stopping;
s4, inserting the fixed frame 16 into the gap between the two square frames 5, and fixedly connecting the fixed frame 16 with the two square frames 5 through bolts;
and S5, re-filling sealing liquid or gas into a sealing cavity surrounded by the high-temperature resistant elastic layer 15, the square-shaped frame 5, the fixed frame 16 and the stop 7.
