Description

Technical Field

[0001] This application relates to the technical field of photovoltaic cell module manufacturing, and particularly to a backplane film sticking device in a photovoltaic cell. Background Art

[0002] Photovoltaic modules are usually encapsulated by a backplane, a lower layer of glue film, a battery string group, an upper layer of glue film, and a glass plate. Among them, there are gaps between adjacent two solar cells in the battery string group and between adjacent two battery strings. It is very difficult to directly absorb or utilize the light energy irradiated into these gaps. In order to improve the light energy utilization rate, the industry adopts sticking reflective film strips at positions corresponding to the inter-cell positions and the inter-string positions on the backplane. The light energy irradiated to the above gap positions is reflected to the glass plate through the reflective film strips, and then reflected to the solar cells through the glass plate, so as to make full use of the light energy at the gap positions.

[0003] Refer to Figure 1 As shown, several reflective film strips extending along the first horizontal direction (such as the Y direction in Figure 1 ) are the inter-cell gap film strips 6 corresponding to the inter-cell positions, and several reflective film strips extending along the second horizontal direction (such as the X direction in Figure 1 ) are the inter-string gap film strips 7 corresponding to the inter-string positions. In the prior art, the film sticking method of the backplane film sticking device is usually: transporting the backplane 3 to a designated position, and the film sticking head pastes the inter-cell gap film strips 6 and the inter-string gap film strips 7 on the upper surface of the backplane 3. Since the reflective film strips are located on the upper surface of the backplane 3, the backplane 3 needs to be flipped before the module is combined with the glass, so that the reflective film strips face down. Flipping the backplane 3 increases the process complexity and requires a separate backplane flipping mechanism, which also increases the manufacturing cost of the module. Utility Model Content

[0004] In order to solve the problems of the prior art, this application provides a backplane film sticking device.

[0005] Specifically, this application provides a backplane film sticking device, including: a handling mechanism and two film sticking mechanisms; one of the film sticking mechanisms is used for implementing inter-cell film sticking on the backplane, and the other film sticking mechanism is used for implementing inter-string film sticking on the backplane. The handling mechanism is used for transporting the backplane to the inter-cell film sticking station for inter-cell film sticking, and after the inter-cell film sticking is completed, transporting the backplane from the inter-cell film sticking station to the inter-string film sticking station for inter-string film sticking;

[0006] The film sticking mechanism includes a film laying table, a film laying component, and a heating component; the film laying table is used for carrying the film strips and the backplane; the film laying component is arranged above the film laying table and is used for laying the film strips on the film laying table; the heating component is arranged below the film laying table and is used for heating the film strips laid on the film laying table from below so that the film strips are adhered to the backplane laid thereon.

[0007] The backplane film pasting device provided by the present application enables two film pasting mechanisms to perform inter - sheet film pasting and inter - string film pasting on the backplane successively. The film laying component in each film pasting mechanism can lay film strips on the film laying table. After the film strips are laid, the handling mechanism places the backplane on the film strips. The heating component is arranged below the film laying table and can heat the film strips from below the backplane to make the film strips adhere to the backplane. After the film strips are pasted, they are located on the lower surface of the backplane. In the subsequent component glass - combining process, it is no longer necessary to reverse the backplane, simplifying the overall manufacturing process of photovoltaic cell components and improving production efficiency.

[0008] In some embodiments, the film laying table for inter - sheet film pasting includes: a frame, a first lifting drive assembly, and a first film strip adsorption table arranged inside the frame;

[0009] The frame is configured to support the backplane at the top;

[0010] The first film strip adsorption table is configured to adsorb and fix the inter - sheet gap film strips laid by the corresponding film laying component;

[0011] The first lifting drive assembly is drivingly connected to the first film strip adsorption table and is used to drive the first film strip adsorption table to lift and lower.

[0012] By adsorbing and fixing the film strips with the first film strip adsorption table, the thin and light film strips can be stably fixed, ensuring the film pasting accuracy of the film strips. By drivingly connecting the first film strip adsorption table with the first lifting drive assembly, when the handling mechanism places the backplane on the top of the frame, the first film strip adsorption table and the adsorbed film strips can be first controlled to descend to the avoidance low position. After the position of the backplane is adjusted, the first film strip adsorption table and the adsorbed film strips are then controlled to rise, so that the film strips contact the lower surface of the backplane, thus avoiding affecting the surface quality of the film strips.

[0013] In some embodiments, there are at least two first film strip adsorption tables, and each first film strip adsorption table is used to adsorb and fix at least one inter - sheet gap film strip; at least one support member for carrying the backplane is arranged on the top surface of the frame, and an avoidance gap for avoiding the support member during lifting is arranged between two adjacent first film strip adsorption tables.

[0014] A specific structural setting of the first film strip adsorption table and the frame is provided. When the first film strip adsorption table descends below the support member under the drive of the first lifting drive assembly, the film strips adsorbed and fixed by it can be separated from the backplane carried by the support member, facilitating the position movement of the backplane without rubbing the film strips.

[0015] In some embodiments, the film pasting mechanism for inter - sheet film pasting further includes a rectifying component, and the rectifying component is configured to clamp the backplane carried to the film laying table at the inter - sheet gap film pasting station and rectify the position of the backplane.

[0016] By arranging a rectifying component at the film laying table at the film pasting station between chips, it is possible to rectify the position of the backplane by using the rectifying component before pasting the film on the backplane, avoiding misalignment of the film strip pasting and ensuring the film pasting accuracy.

[0017] In some embodiments, the rectifying component includes an X-direction guide rail, a Y-direction guide rail, and a pair of rectifying members. At least one rectifying member is arranged on each side of the film laying table for inter-chip film pasting. The X-direction guide rail and the Y-direction guide rail are both horizontally arranged and perpendicular to each other;

[0018] The rectifying member is configured to slide along the X-direction guide rail or the Y-direction guide rail to approach or move away from the backplane laid on the film laying table.

[0019] By arranging at least one rectifying member on each side of the backplane, the backplane can be rectified quickly and accurately.

[0020] In some embodiments, the film pasting mechanism for inter-chip film pasting further includes a punching component;

[0021] The punching component is arranged below the film laying table at the film pasting station between chips. An avoidance channel is arranged on the film laying table at the film pasting station between chips corresponding to the position of the inter-chip film strip in the middle of the backplane. The punching component is configured to pass through the avoidance channel to punch through holes corresponding to the positions of the lead holes on the backplane on the inter-chip film strip in the middle of the backplane.

[0022] By arranging the punching component below the film laying table at the film pasting station between chips, after the inter-chip film pasting is completed at the film pasting station between chips, the punching component can punch one inter-chip film strip in the middle of the backplane, facilitating the subsequent combination of glass. The leads in the battery string group of the photovoltaic module extend through the punched part and the lead holes on the backplane and are installed with the junction box.

[0023] In some embodiments, the punching component includes a punch longitudinally arranged for punching the inter-chip film strip in the middle of the backplane, and a second lifting drive component for driving the punch to lift and lower.

[0024] By driving the punch to punch the inter-chip film strip in the middle of the backplane through the second lifting drive component and driving the punch to descend after punching, it is possible to avoid affecting the subsequent laying and pasting of the film strip and the backplane.

[0026] After the inter-string film strip is laid on the second film strip adsorption table, the second film strip adsorption table can directly carry the backplane without adjusting the position of the backplane, and the structure is simpler and more compact.

[0027] In some embodiments, the film laying table is further configured to adsorb each film strip, and an avoidance hole is formed in the film laying table for the heating component to pass through to heat the film strip carried and adsorbed on the film laying table; the heating component below the film laying table heats the film strip carried above the film laying table through the avoidance hole.

[0034] By cooperating with the first translation driving component and the third lifting driving component to drive the heating component to translate and lift, it is possible to realize sequential close-range heating of at least two points to be heated on the film strip by the heating component. Through the guiding of the first translation guide rail, it is possible to prevent the position of the heating component from shifting during the sequential spot-ironing process.

[0037] Using a plurality of heating components to simultaneously perform spot-ironing on the corresponding film strip above can improve the speed of spot-ironing the film strip and enhance the production efficiency.

[0038] In some embodiments, a fourth lifting drive assembly is further provided below the film laying table;

[0039] Each heating assembly is connected to the fourth lifting drive assembly and is driven to lift simultaneously by the fourth lifting drive assembly.

[0040] All the heating assemblies lift simultaneously, enabling the spot ironing of all the film strips to be completed simultaneously, further improving the production efficiency.

[0077] The following describes some embodiments of the present application with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present application and are not intended to limit the protection scope of the present application.

[0078] As described in the background art, the film pasting method of the current backplane film pasting device is usually as follows: the backplane is conveyed to a specified position, and the film pasting head pastes the inter-chip gap film strip and the inter-string gap film strip on the upper surface of the backplane. Since the reflective film strip is located on the upper surface of the backplane, the backplane needs to be flipped before the components are combined with glass to make the reflective film strip face down. Flipping the backplane increases the process complexity and requires a separate backplane flipping mechanism, which also increases the manufacturing cost of the components. To solve the above problems, the present application creatively proposes a backplane film pasting device. The reflective film strip and the backplane are sequentially laid above the film laying table, and a heating component is arranged below the film laying table to heat the reflective film strip laid on the film laying table from below so that the reflective film strip is bonded to the backplane laid on the reflective film strip. Before the subsequent components are combined with glass, there is no need to flip the backplane to make the reflective film strip face down, reducing the process complexity and eliminating the need for a separate backplane flipping mechanism, thereby reducing the manufacturing cost of the components.

[0079] The following will specifically elaborate on the present application through specific embodiments.

[0080] An embodiment of the present application provides a backplane film pasting device, in combination with Figure 1 , referring to Figures 2 to 7 shown, including: a handling mechanism 1 and two film pasting mechanisms 2; one of the film pasting mechanisms is used to perform inter-chip film pasting on the backplane 3, denoted as the inter-chip film pasting mechanism 2A, and the other film pasting mechanism is used to perform inter-string film pasting on the backplane, denoted as the inter-string film pasting mechanism 2B. The handling mechanism 1 is used to convey the backplane 3 to the inter-chip film pasting station M for inter-chip film pasting, and after the inter-chip film pasting is completed, convey the backplane 3 from the inter-chip film pasting station M to the inter-string film pasting station N for inter-string film pasting; the inter-chip film pasting station M refers to the place where the inter-chip gap film strip 6 and the backplane 3 are laid and bonded, and the inter-string film pasting station N refers to the place where the inter-string gap film strip 7 and the backplane 3 are laid and bonded.

[0081] The film pasting mechanism 2 includes a film laying table 21, a film laying assembly 22, and a heating assembly 23; the film laying table 21 is used to carry the film strip and the backplane 3; the film laying assembly 22 is arranged above the film laying table 21 and is used to lay the film strip on the film laying table 21; the heating assembly 23 is arranged below the film laying table 21 and is used to heat the film strip laid on the film laying table 21 from below so that the film strip is bonded to the backplane 3 laid on it.

[0082] The film strips to be pasted on the backplane 3 are divided into an inter-chip gap film strip 6 and an inter-string gap film strip 7. Taking the backplane 3 shown in Figure 1 as an example, several reflective film strips extending along the first horizontal direction (i.e., the Y direction in Figure 1 ) are the inter-chip gap film strips 6 corresponding to the inter-chip positions. As shown in Figure 1 , there are 25 inter-chip gap film strips 6 in total; along the second horizontal direction (i.e., Figure 1A plurality of reflective film strips extending in the X direction (in the figure) i.e., the string gap film strips 7 corresponding to the positions between the strings. The second horizontal direction is perpendicular to the first horizontal direction. Among them, there are two groups of string gap film strips 7 arranged side by side in the second horizontal direction, and each group contains the same number of string gap film strips 7. For example, Figure 1 each group in Figure 1 contains 7 string gap film strips 7, and there are a total of 14 string gap film strips 7 on the entire backplane. The number of inter - cell gap film strips 6 and string gap film strips 7 on the backplane mainly depends on the number of cell strings in the photovoltaic module and the number of solar cells included in each cell string.

[0083] The working process of the backplane film - pasting device in the embodiment of the present application is as follows:

[0084] The film - laying component 22 in the inter - cell film - pasting mechanism 2A lays the inter - cell gap film strips 6 on the film - laying table 21 in the inter - cell film - pasting mechanism 2A. The handling mechanism 1 transports the backplane 3 from the feeding area to the inter - cell film - pasting station M and places it on the laid inter - cell gap film strips 6. The heating component 23 in the inter - cell film - pasting mechanism 2A heats the laid inter - cell gap film strips 6 from below, so that the inter - cell gap film strips 6 are bonded to the backplane 3 laid thereon. The film - laying component 22 in the inter - string film - pasting mechanism 2B lays the string gap film strips 7 on the film - laying table 21 in the inter - string film - pasting mechanism 2B. The handling mechanism 1 then transports the backplane with the inter - cell gap film strips 6 pasted thereon to the inter - string film - pasting station N and places it on the laid string gap film strips 7. The heating component 23 in the inter - string film - pasting mechanism 2B heats the laid string gap film strips 7 from below, so that the string gap film strips 7 are bonded to the backplane 3 laid thereon. The heating components 23 in both the inter - cell film - pasting mechanism 2A and the inter - string film - pasting mechanism 2B heat the film strips from below the backplane 3, so that the inter - cell gap film strips 6 and the string gap film strips 7 are pasted on the backplane 3. After the inter - cell gap film strips 6 and the string gap film strips 7 are pasted well, they are located on the lower surface of the backplane 3. In the subsequent component glass - combining process, there is no need to reverse the backplane 3, which simplifies the overall manufacturing process of the photovoltaic cell module and improves the production efficiency. In some embodiments, referring to Figures 4 to 7 as shown, the film - laying table 21 for inter - cell film - pasting in the inter - cell film - pasting mechanism 2A includes: a frame 2a1, a first lifting drive assembly 2a2, and a first film strip adsorption table 2a3 arranged inside the frame 2a1;

[0085] The frame 2a1 is configured to support the backplane 3 at the top; the first film strip adsorption table 2a3 is configured to adsorb and fix the sheet gap film strip 6 laid by the corresponding film laying assembly 22; the first lifting drive assembly 2a2 is drivingly connected to the first film strip adsorption table 2a3 for driving the first film strip adsorption table 2a3 to lift; by adsorbing and fixing the sheet gap film strip 6 with the first film strip adsorption table 2a3, the thin and light sheet gap film strip 6 can be stably fixed, ensuring the film sticking accuracy of the film strip; by drivingly connecting the first film strip adsorption table 2a3 with the first lifting drive assembly 2a2, when the handling mechanism 1 places the backplane 3 on the top of the frame 2a1, the first film strip adsorption table 2a3 and the adsorbed sheet gap film strip 6 can be first controlled to descend to the avoidance low position, and after the position of the backplane 3 is adjusted, the first film strip adsorption table 2a3 and the adsorbed sheet gap film strip 6 are then controlled to rise, so that the sheet gap film strip 6 contacts the lower surface of the backplane 3, thereby avoiding affecting the position accuracy of the sheet gap film strip 6 and the surface quality of the sheet gap film strip 6 due to directly adjusting the position of the backplane 3 on the sheet gap film strip 6.

[0086] Optionally, referring to Figure 4 and Figure 5 as shown, the first film strip adsorption table 2a3 is provided with at least two (such as Figure 4 5 in Figure 5 ), and each first film strip adsorption table 2a3 is used for adsorbing and fixing at least one sheet gap film strip 6.

By the cooperation of the first translation drive assembly and the third lifting drive assembly to drive the heating assembly to translate and lift, the heating assembly 23 can sequentially heat at least two points to be heated on the film strip at a close distance. Through the guiding of the first translation guide rail, the position of the heating assembly 23 can be prevented from shifting during the sequential spot-welding process. The first translation drive assembly drives the third lifting drive assembly to translate along the first translation guide rail, so that the heating assembly 23 connected to the third lifting drive assembly reaches the position below the film strip to be heated, and then the third lifting drive assembly drives the heating assembly 23 to rise to spot-weld the film strip.
