As shown in FIGS. 1 and 2, an embodiment of the present disclosure provides a laminating apparatus including a cover 1, a table 2, and a pressing member 3. The cover 1 is movable relative to the table 2 for mating with the table 2 to form a sealed laminated cavity. The pressure member 3 is located in the sealed laminated cavity for applying pressure to the flexible solar cell module X.

The second connecting member 5 is connected between the cover 1 and the table 2, and the second connecting member 5 is used to drive the cover 1 to move up and down. The structure of the second connecting member 5 may be various. As an example, the second connecting member 5 may be a bolt assembly including: a screw, a bolt head disposed on the screw, and a sleeve disposed on the bolt head. Upper nut and lower nut. The bolt head is fixed on the side wall of the worktable 2. The side wall of the cover body 1 is provided with a fixing member opposite to the bolt head. The fixing member is movably fitted on the screw, and the upper nut and the lower nut are respectively fixed and fixed. The upper and lower ends of the piece are offset. When the cover 1 needs to be moved, it is only necessary to loosen the nut on the bolt. After the cover 1 is moved to a suitable position, the nut can be tightened.

In order to ensure the smooth progress of the subsequent vacuuming operation, as shown in FIG. 2, the laminating apparatus further includes: a partitioning plate 7 for separating the sealed lamination chamber. A first sealing cavity Y is formed between the separating plate 7 and the cover body 1, and a second sealing cavity Z is formed between the separating plate 7 and the table 2.

The spacer 7 may be disposed on a side close to the table 2. The top wall of the cover 1 is provided with a first chamber forming a first sealed chamber Y, and the upper side of the table 2 is provided with a second chamber forming a second sealed chamber Z.

Specifically, the insulation panel 7 may be an elastic insulation panel such as a silica gel panel. During the laminating operation, it is necessary to inflate the first chamber and evacuate the second chamber, and the inflated first chamber protrudes from the second chamber by the gas pressure. The shape is further brought into contact with the pressure-applying member 3, and pressure is applied to the pressure-applying member 3 to perform a laminating operation.

The manner in which the pressing member 3 is disposed in the laminating device may be various, specifically:

As an implementation manner, in order to facilitate the fixing of the pressure-applying member 3 on the cover body 1, the pressure-applying member 3 can be connected to the cover body 1 through the first connecting member 4, and between the pressure-applying member 3 and the cover body 1. The gap is adjustable. The first connector 4 is sealingly passed through the sealed lamination chamber.

When the cover 1 and the table 2 cooperate to form the first sealed cavity Y and the second sealed cavity Z, a gap for pressing the flexible solar module battery assembly X is formed between the pressing member 3 and the table 2. That is, the lower surface of the flexible solar module battery X is in contact with the table 2, and the upper surface is in contact with the pressing member 3. In order to prevent the pressure member 3 from damaging the flexible solar module battery X, the pressure member 3 is preferably an elastic connection member. Specifically, in order to ensure the pressure application effect on the flexible solar module battery X, it may be set as an elastic plate structure, for example, :silicone board.

As another implementation, in order to facilitate the fixing of the pressing member 3 on the table 2, the pressing member 3 may be connected to the table 2 through the telescopic member.

Specifically, in order not to affect the seal between the cover 1 and the table 2, the stretchable member may be disposed in the second sealed chamber Z between the partition plate 7 and the table 2. When performing the laminating operation, it is only necessary to contract the telescopic member until the pressing member 3 is pressed against the flexible solar module battery assembly X.

Wherein, the telescopic member may be a telescopic rod, and the minimum telescopic limit value of the telescopic rod is smaller than the thickness of the flexible solar module battery X, that is, when the telescopic rod is contracted, the pressing member 3 can be in contact with the flexible solar module battery assembly X, and is flexible. The solar module battery assembly X is pressurized.

In order to ensure the lamination effect, the fault tolerance rate during lamination work is also improved. As shown in FIG. 3, the pressing member 3 includes a contact portion 302 and a redundant portion 303 which is circumferentially disposed on the contact portion 302. The contact portion 302 is for applying pressure to the flexible solar cell module X.

Wherein, the area of the contact portion 302 matches the area of the flexible solar module battery X, and when the pressure member 3 comes into contact with the flexible solar module battery X, even if the pressure member 3 is deflected, the redundant portion 302 can be secured. It is in contact with the flexible solar module battery X.

The following describes the operation of the laminating apparatus: the laminating apparatus is started up and reaches the preheating temperature, and the flexible solar module battery X is placed on the table 2, at which time the flexible solar module battery X is placed on the table 2, and the cover is driven. 1 moves downward, at this time, the pressure-applying member 3 first contacts the flexible solar module battery X, and presses the flexible solar module battery X by its own gravity, the cover body 1 continues to move downward, and cooperates with the table 2 to form a sealed laminated cavity. At this time, the heating process is started, and then the vacuuming process is started (that is, the vacuum pump is used to pass the small air holes on the table 2, and the gas in the chamber is extracted to make it reach a vacuum state), and the lamination processing of the flexible solar module battery X is completed. The heating procedure is turned off, the cover 1 is moved up, and the entire lamination process is completed.

In the above processing process, the flexible solar module battery X can absorb heat energy from the worktable 2 and the pressure-applying member 3, and the flexible solar module battery X is heated up and down at the same time to increase the heating rate, which can effectively alleviate the temperature difference and significantly improve the bubble problem; During the vacuuming phase, the pressure member 3 itself acts on the flexible solar module battery X, inhibiting the organic polymer material from being freely contracted into the front back plate, preventing the material from being deformed by curling and local bulging, resulting in wrinkles due to uneven heating.

It will be understood by those skilled in the art that the sealing lamination chamber must be kept absolutely sealed when the laminating device is subjected to lamination work, and the thickness of the pressing member 3 should be less than that in order to prevent the pressing member 3 from affecting the sealing of the sealing lamination chamber. The depth of the second sealing chamber Z; at the same time, in order to ensure that the pressure member 3 has sufficient pressure to be applied to the flexible solar module battery X, the thickness of the pressing member 3 should be greater than or equal to 3 mm; after testing, the thickness of the pressing member 3 When it is greater than or equal to 3 mm, wrinkles and bubbles of the flexible solar module battery X are remarkably improved.

After testing, when the diameter of the connecting wire is less than or equal to 1 mm, the sealing property is not affected at all. Due to the small diameter of the flexible connecting wire, in order to ensure the strength of the flexible connecting wire and avoid the disconnection of the flexible connecting wire, the pressing member 3 is dropped, and the flexible connecting wire is preferably made of a high-strength technology, for example, a steel wire.

Further, at least two lifting lugs 6 are provided on the outer side of the cover body 1. Preferably, the lifting lugs 6 are arranged in four, and the lifting lugs 6 are provided with a first connecting hole 601.
