DETAILED DESCRIPTION

[0034] In order for those skilled in the art to better understand the technical solutions of the present application, first, a packaging process of a solar cell which the inventor of the present application is studying is introduced. In the packaging process of the solar cell, first, an interconnection strip and a plurality of battery pieces are laid, and the laid interconnection strip and the plurality of battery pieces are put into a welding chamber, and a welding device in the welding chamber is used to weld the interconnection strip and the plurality of battery pieces, so that the plurality of battery pieces are connected in series to form a battery string. Then, the battery string is taken out of the welding chamber, and a glass plate provided with a first adhesive film layer is prepared, the plurality of battery strings are laid on the first adhesive film layer, and a bus bar is laid with the plurality of battery strings, and then the laid glass plate, the first adhesive film layer, the bus bar and the plurality of battery strings are put into the welding chamber, and the bus bar and the plurality of battery strings are welded by the welding device, so that the plurality of battery strings are connected in parallel to form a battery piece group, and the battery piece group is preliminarily bonded to the glass plate through the first adhesive film layer. Then, the battery piece group, the first adhesive film layer and the glass plate are taken out of the welding chamber, a second adhesive film layer and a back plate are laid on the back of the battery piece group in sequence, and then the laid battery piece group, the first adhesive film layer, the glass plate, the second adhesive film layer and the back plate are put into a laminating chamber, and a laminating device in the laminating chamber is used to laminate and weld the battery piece group, the first adhesive film layer, the glass plate, the second adhesive film layer and the back plate, so as to complete the packaging laminating process of the solar cell.

[0035] For the packaging process of the solar cell, since the welding device and the laminating device are respectively used to weld in the welding chamber and the laminating chamber which are two independent chambers, the packaging efficiency of the solar cell is low, and the uncertainty of the packaging of the solar cell is increased. In addition, since the structure of the welding device is relatively complex and the welding yield is low, the production capacity and yield of the solar cell are low.

[0036] In order for those skilled in the art to better understand the technical solutions of the present application, the packaging laminating device, the equipment and the process method provided by the present application are described in detail below in combination with the drawings.

[0037] As shown in Figures 1-5 The present application provides a packaging laminating device, which comprises a first laminating component 1, a second laminating component 2 and a microwave assembly 3. The first laminating component 1 and the second laminating component 2 are oppositely arranged and can approach or move away from each other in the opposite direction, for laminating and welding the battery laminating assembly 5. The microwave assembly 3 is arranged on the first laminating component 1 and / or the second laminating component 2, for transmitting the microwaves generated by the microwave assembly 3 to the battery laminating assembly 5 through the first laminating component 1 and / or the second laminating component 2, so as to pre-weld the battery laminating assembly 5 by using microwaves.

[0038] In this way, the microwave assembly 3 can be used to weld the plurality of battery pieces 511 in the battery piece group 51 together, and the first laminating component 1 and the second laminating component 2 can be used to laminate and weld the battery laminating assembly 5, so that the packaging laminating device provided by the present application has the functions of both a welding device and a laminating device. Therefore, when performing the packaging process of the solar cell, it is not necessary to use a welding device and a laminating device to perform welding and laminating respectively, but only the packaging laminating device provided by the present application can be used to pre-weld the battery laminating assembly 5 to weld the plurality of battery pieces 511 together, and to laminate and weld the battery laminating assembly 5, thereby improving the production capacity and yield of the solar cell.

[0039] As shown in Figure 5 The packaging laminating device provided by the present application is described below by taking a battery laminating assembly 5 as an example. Before the battery laminating assembly 5 is laminated and welded by using the packaging laminating device provided by the present application, the battery laminating assembly 5 needs to be prepared first. For example, in actual application, the interconnection strip and the plurality of battery pieces 511 can be laid to form a battery string which is laid but not welded, and a transparent panel 53 laid with a first adhesive layer 52 is prepared, and then the plurality of battery strings which are laid but not welded are laid on the first adhesive layer 52, and the bus bar is laid with the plurality of battery strings, so as to form a battery piece group 51 which is laid but not welded on the first adhesive layer 52. Then, the second adhesive layer 54 and the back plate 55 can be laid on the back of the battery piece group 51 in sequence, that is, the second adhesive layer 54 can be laid on the back of the battery piece group 51 first, and then the back plate 55 is laid on the side of the second adhesive layer 54 away from the battery piece group 51, thereby forming the battery laminating assembly 5.

[0040] Then, the battery laminated assembly 5 can be put into the packaging laminating chamber, and the first laminating component 1 and the second laminating component 2 in the packaging laminating chamber are respectively located on the front surface and the back surface of the battery laminated assembly 5, and the first laminating component 1 and the second laminating component 2 are separated from the front surface and the back surface of the battery laminated assembly 5 (as shown in Figure 1 and Figure 2 That is, the first laminating component 1 and the second laminating component 2 are separated from the transparent panel 53 and the back plate 55 respectively. At this time, the microwave generated by the microwave assembly 3 can be transmitted to the first laminating component 1 and / or the second laminating component 2, and the first laminating component 1 and / or the second laminating component 2 can transmit the microwave to the battery laminated assembly 5. The microwave can generate electromagnetic eddy current in the components (for example, the bus bar, the interconnection strip and the grid line of the battery sheet 511) having the conductive material 512 in the battery laminated assembly 5, so as to increase the temperature of the bus bar, the interconnection strip and the grid line of the battery sheet 511, thereby enabling the interconnection strip to be pre-welded with the grid line of the battery sheet 511, enabling the multiple battery sheets 511 to be connected in series to form a battery string, and enabling the interconnection strip to be pre-welded with the bus bar, enabling the multiple battery strings to be connected in parallel to form the battery sheet group 51, thereby realizing the pre-welding of the battery laminated assembly 5.

[0041] Then, the first laminating component 1 and the second laminating component 2 can be moved towards each other in the opposite directions and be in contact with the front surface and the back surface of the battery laminated assembly 5 respectively (as shown in Figure 3 and Figure 4 That is, the first laminating component 1 and the second laminating component 2 are in contact with the transparent panel 53 and the back plate 55 respectively. At this time, the first laminating component 1 and the second laminating component 2 can be used to perform the laminated welding on the battery laminated assembly 5, so as to press and weld the transparent panel 53, the first adhesive layer 52, the battery sheet group 51, the second adhesive layer 54 and the back plate 55 together.

[0042] It can be seen that the packaging laminating device provided by the embodiment of the present application can not only pre-weld the multiple battery sheets 511 together, but also perform the laminated welding on the battery laminated assembly 5, thereby improving the production capacity and the yield of the solar cell. Moreover, by pre-welding the battery laminated assembly 5 before performing the laminated welding on the battery laminated assembly 5, the components having the conductive material 512 in the battery laminated assembly 5 can be prevented from moving relative to the battery sheet 511 due to the extrusion of the first laminating component 1 and the second laminating component 2, thereby improving the yield of the solar cell.

[0043] In actual application, when the first laminated component 1 and the second laminated component 2 are respectively in contact with the front surface and the back surface of the battery laminated assembly 5, the microwave assembly 3 can also generate microwaves to weld the battery laminated assembly 5 by using the microwaves, so as to further improve the production capacity of the solar cell.

[0044] However, the packaging laminating device provided by the embodiment of the present application is not limited to the lamination and welding of the battery laminated assembly 5 provided with the bus bar and the interconnection bar. For example, when the battery laminated assembly 5 is prepared, the transparent panel 53 provided with the first adhesive layer 52 can be prepared first, and the plurality of battery pieces 511 can be arranged on the first adhesive layer 52, so as to form the battery piece group 51 arranged on the first adhesive layer 52 but not welded. Then, the conductive adhesive can be coated on the battery piece group 51, and the second adhesive layer 54 and the back plate 55 can be arranged on the back surface of the battery piece group 51 in sequence, so as to form the battery laminated assembly 5. In this battery laminated assembly 5, the bus bar and the interconnection bar are not arranged, but the conductive adhesive coated on the battery piece group 51 is used to replace the bus bar and the interconnection bar.

[0045] For the battery laminated assembly 5 coated with the conductive adhesive, the microwaves transmitted to the battery laminated assembly 5 can generate electromagnetic eddy currents in the components (for example, the conductive adhesive and the grid lines of the battery pieces 511) of the battery laminated assembly 5 provided with the conductive material 512, so as to increase the temperature of the conductive adhesive and the grid lines of the battery pieces 511, dry the conductive adhesive, and make the conductive adhesive pre-welded with the grid lines of the battery pieces 511, so as to make the plurality of battery pieces 511 connected in series to form the battery string, and make the conductive adhesive pre-welded with each other, so as to make the plurality of battery strings connected in parallel to form the battery piece group 51, thereby realizing the pre-welding of the battery laminated assembly 5 coated with the conductive adhesive.

[0046] Optionally, the bus bar can include a tin-plated copper strip or an aluminum strip.

[0047] Optionally, the interconnection bar can include a tin-plated copper strip or an aluminum strip.

[0048] In actual application, the bus bar and the interconnection bar can be collectively referred to as a welding strip.

[0049] In actual application, the transparent panel 53 can be used as the light incident surface of the solar cell.

[0050] Optionally, the transparent panel 53 can be a glass plate.

[0051] Optionally, the back plate 55 can be transparent or opaque.

[0052] Optionally, the transparent back plate 55 can be a glass plate.

[0053] Optionally, the second adhesive layer 54 can be transparent or opaque.

[0054] Optionally, the conductive glue can include resin conductive glue, silver paste conductive glue or silver-aluminum paste conductive glue.

[0055] Optionally, the time for laminating and welding can be 500s-900s.

[0056] As shown in Figure 1 and Figure 3 In an embodiment of the present application, the first laminated component 1 and the second laminated component 2 can be provided with a microwave assembly 3. This can improve the efficiency of pre-welding the battery laminated assembly 5, thereby further improving the production capacity of the solar cell.

[0057] As shown in Figure 1 and Figure 3 In an embodiment of the present application, the microwave assembly 3 can include a microwave generating component 31 and a microwave transmission component 32. The microwave generating component 31 can be electrically connected to a power supply device (not shown in the figure) for generating microwaves when powered on. The microwave transmission component 32 is electrically connected to the microwave generating component 31 and to the first laminated component 1 and / or the second laminated component 2 for transmitting microwaves to the first laminated component 1 and / or the second laminated component 2.

[0058] That is, the power supply device can supply power to the microwave generating component 31, which can generate microwaves when powered on and transmit them to the microwave transmission component 32. When the microwave transmission component 32 is electrically connected to the first laminated component 1, it can transmit waves to the first laminated component 1, so that the microwaves are transmitted to the battery laminated assembly 5 through the first laminated component 1. When the microwave transmission component 32 is electrically connected to the second laminated component 2, it can transmit waves to the second laminated component 2, so that the microwaves are transmitted to the battery laminated assembly 5 through the second laminated component 2. When the microwave transmission component 32 is electrically connected to both the first laminated component 1 and the second laminated component 2, it can transmit waves to the first laminated component 1 and the second laminated component 2, so that the microwaves are transmitted to the battery laminated assembly 5 through the first laminated component 1 and the second laminated component 2.

[0059] In an embodiment of the present application, the microwave generating component 31 can include a magnetron.

[0060] In an embodiment of the present application, the microwave transmission component 32 can include a waveguide.

[0061] In an embodiment of the present application, the microwave assembly 3 can further include a microwave frequency adjusting component (not shown in the figure). The microwave generating component 31 is electrically connected to the power supply device through the microwave frequency adjusting component, which is used to adjust the frequency of the microwaves generated by the microwave generating component 31. This can improve the scope of application and flexibility of use of the packaging laminating device.

[0062] For example, during the pre-welding of the battery laminate assembly 5, a microwave frequency tuning component can be used to adjust the microwave frequency to a first preset frequency. The microwave at the first preset frequency can generate electromagnetic eddy currents in the components of the battery laminate assembly 5 containing conductive material 512, thereby raising the temperature of the components containing conductive material 512 and thus achieving the pre-welding of the battery laminate assembly 5. After the pre-welding of the battery laminate assembly 5, the microwave frequency can be adjusted to a second preset frequency using the microwave frequency tuning component. The microwave at the second preset frequency can raise the temperature of the first adhesive layer 52 and the second adhesive layer 54 in the battery laminate assembly 5, thereby improving the lamination welding efficiency during the lamination welding of the battery laminate assembly 5, and further increasing the production capacity of the solar cells.

[0063] By pre-welding the battery laminate assembly 5 before raising the temperature of the first adhesive layer 52 and the second adhesive layer 54, the deformation of the components with conductive material 512 in the battery laminate assembly 5 due to the temperature rise of the first adhesive layer 52 and the second adhesive layer 54 can be avoided, which would affect the cross-linking of the components with conductive material 512 with the battery cell 511, thereby improving the yield of the solar cell.

[0064] In one embodiment of the present invention, the frequency of the microwave may include 5GHz-13GHz and 900MHz-5GHz. Specifically, 5GHz-13GHz can be used as a first preset frequency for the microwave, and 900MHz-5GHz can be used as a second preset frequency for the microwave.

[0065] like Figure 1 and Figure 3 As shown, in one embodiment of the present invention, the microwave component 3 may further include a transformer component 33. The microwave generating component 31 is electrically connected to the power supply equipment through the transformer component 33. The transformer component 33 is used to adjust the voltage applied to the microwave generating component 31.

[0066] In other words, the transformer component 33 can be electrically connected to the microwave generator component 31 and the power supply equipment respectively, and the voltage output by the power supply equipment is applied to the microwave generator component 31 through the adjustment of the transformer component 33.

[0067] Optionally, the transformer component 33 can be a transformer.

[0068] In one embodiment of the present invention, a heating component (not shown in the figure) may be provided on the first laminating component 1 and / or the second laminating component 2. The heating component is used to weld the battery laminating component 5 by heating it.

[0069] In other words, when laminating and welding the battery laminate assembly 5, the heating assembly can heat the battery laminate assembly 5 to achieve the welding of the battery laminate assembly 5.

[0070] Optionally, the heating component may include any one of oil heating elements, electric heating elements, oil-electric hybrid heating elements, infrared heating lamps, and laser heating elements.

[0071] like Figure 3 As shown, in one embodiment of the present invention, the encapsulation lamination device may further include a vacuum component 4, which is connected to the space between the first lamination component 1 and the second lamination component 2, and is used to vacuum the battery lamination component 5 by vacuuming the space between the first lamination component 1 and the second lamination component 2.

[0072] In practical applications, after the pre-welding of the battery laminate 5 and before the lamination welding (optionally, the time can be 200s-400s), or from the time after pre-welding until the lamination welding is completed, the air extraction component 4 can be used to extract air from the battery laminate 5 to remove air bubbles from the first adhesive layer 52 and the second adhesive layer 54, thereby improving the crosslinking rate and reliability of the battery laminate 5 during lamination welding, and thus further improving the yield of solar cells.

[0073] Optionally, the air extraction assembly 4 may include an air extraction pump 41 and an air extraction pipe 42. One end of the air extraction pipe 42 is connected to the air extraction pump 41, and the other end is connected to the space between the first laminating component 1 and the second laminating component 2, so that the air extraction pump 41 can extract air from the space between the first laminating component 1 and the second laminating component 2 through the air extraction pipe 42.

[0074] This invention also provides an encapsulation lamination apparatus, including an encapsulation lamination chamber and an encapsulation lamination device as provided in this invention embodiment. The encapsulation lamination device is disposed in the encapsulation lamination chamber and is used to perform an encapsulation lamination process on the battery lamination assembly 5.

[0075] The encapsulation lamination equipment provided in this embodiment of the invention, by setting the encapsulation lamination device provided in this embodiment of the invention in the encapsulation lamination chamber, can both pre-weld the battery lamination assembly 5 and weld multiple battery cells 511 together in the encapsulation lamination chamber, and also perform lamination welding on the battery lamination assembly 5, thereby improving the production capacity and yield of solar cells.

Microwaves are generated by microwave component 3 and transmitted to the first laminating component 1 and / or the second laminating component 2 to transmit microwaves to the battery laminating component 5 through the first laminating component 1 and / or the second laminating component 2, and to pre-weld the battery laminating component 5.

[0080] S4. Bring the first laminating component 1 and the second laminating component 2 closer to each other in their opposite directions, so that they contact the front and back sides of the battery laminating assembly 5 respectively, and perform lamination welding on the battery laminating assembly 5.
