[0034] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.
[0035] See Figure 1As shown, this application provides a separation device 100, which includes a carrier 110, a first air knife assembly 120, and a plurality of second air knife assemblies 130. The separation device 100 is used for separating stacked solar cells. The carrier 110 has a carrying space 111 for carrying solar cells. If the separation device 100 is set in a conveying device, during the conveying of stacked solar cells, the stacked solar cells can be fed into the carrying space 111 for separation.
[0036] A first air knife assembly 120 and multiple second air knife assemblies 130 are all disposed on the carrier 110. The first air knife assembly 120 is located on the top side of the support space 111 and is used to blow air toward the top solar cell. For example, the top solar cell is the uppermost layer of stacked solar cells. The first air knife assembly 120 can blow compressed air toward the top solar cell to apply positive air pressure, preventing the stacked solar cells from becoming loose during separation. At least two second air knife assemblies 130 are spaced apart on opposite sides of the support space 111. Figure 1 On the left and right sides of the carrier 110 shown, the second air knife assembly 130 is used to blow air towards the gap between two adjacent battery cells. For example, the second air knife assembly 130 can blow compressed air towards the gap between two adjacent battery cells to separate them. The two second air knife assemblies 130 on opposite sides blow air synchronously, which can keep the battery cells horizontal during the separation process. Thus, when the carrier space 111 carries stacked battery cells, the second air knife assembly 130 blows air towards the gap between two adjacent battery cells to form an air-blocking airflow layer between the two adjacent battery cells, performing air flotation separation of the stacked battery cells. Meanwhile, the first air knife assembly 120 blows air towards the top battery cell to apply positive air pressure to the top battery cell, preventing the stacked battery cells from becoming loose during the air flotation separation process and maintaining the integrity of the stacked battery cells.
[0037] The aforementioned separation device 100, through the first air knife assembly 120 and the second air knife assembly 130, can form an air flotation isolation layer between two adjacent solar cells, thereby performing air flotation separation of the stacked solar cells. Compared to the traditional method of placing a release paper between two adjacent solar cells to prevent damage to the surface of the solar cells, the air flotation isolation method prevents adjacent solar cells from contacting and rubbing with other components, avoiding defects such as scratches and abrasions during the separation process. Furthermore, the stacked solar cells maintain good neatness during the unloading, receiving, and packaging processes.
[0038] In one embodiment, see Figure 1 and Figure 2As shown, the first air knife assembly 120 includes a first air knife bracket 121 and a first air knife 122. The first air knife bracket 121 is disposed on the carrier 110. The first air knife bracket 121 is disposed on the carrier 110 by means of welding, screwing, etc., so as to realize the installation and fixation of the first air knife assembly 120 on the carrier 110. The first air knife 122 is disposed on the first air knife bracket 121, and the first air knife 122 is located at the top of the bearing space 111. The first air knife 122 is used to blow air toward the top battery cell. If there is a gap between the first air knife 122 and the top battery cell, the airflow blown out by the first air knife 122 acts on the top battery cell to compress the stacked battery cells into a whole, avoid the loosening of the stacked battery cells during the air flotation isolation process, and maintain the integrity of the stacked battery cells.
[0039] Because solar cells come in various sizes and specifications, blowing air off-center from the cell center can cause tilting, warping, and other defects during separation. Therefore, in one embodiment, see [reference needed]. Figure 1 and Figure 2 As shown, the first air knife 122 is movably mounted on the first air knife bracket 121, or the first air knife bracket 121 is movably mounted on the carrier 110. Thus, for different specifications of battery cells, the first air knife 122 or the first air knife bracket 121 can be moved to adjust the relative position of the first air knife 122 and the top battery cell, positioning the first air knife 122 directly above the top battery cell, and ensuring that the first air knife 122 blows air towards the center area of the top battery cell. This ensures that the airflow applied by the first air knife 122 to the top battery cell has a gradual change in magnitude, preventing the top battery cell from tilting, warping, or other adverse phenomena during compression.
[0040] Specifically, see Figure 1 and Figure 2 As shown, the first air knife bracket 121 is provided with a first sliding groove 1211. Preferably, the first sliding groove 1211 is integrally formed into the first air knife bracket 121 by injection molding, extrusion, or other methods to simplify the molding process of the first air knife bracket 121 in forming the first sliding groove 1211. The first air knife 122 has a first sliding post 1221, which is slidably disposed in the first sliding groove 1211, such as when the first sliding post 1221 is inserted into the first sliding groove 1211. Thus, by sliding the first sliding post 1221 within the first sliding groove 1211, the first sliding post 1221 drives the first air knife 122 to move, thereby changing the position of the first air knife 122 and adjusting the relative position of the first air knife 122 and the top battery cell.
[0041] It should be noted that the connection structure between the first air knife 122 and the first air knife support 121 can also be a slide rail and slide table module, a gear and rack module, or other structural forms that can realize the position movement of the first air knife 122. This application does not limit the specific method of the connection structure between the first air knife 122 and the first air knife support 121.
[0042] Further, see Figure 1 and Figure 2 As shown, the first air knife assembly 120 also includes a first airflow valve. The first air knife 122 has multiple first air outlets 1222, and the first airflow valve is used to control the airflow rate of the first air outlets 1222. For example, the first air outlets 1222 are connected to an air passage, and the first airflow valve controls the airflow rate entering the first air outlets 1222. During the separation of stacked battery cells, if the airflow rate of the first air outlets 1222 is small, the positive air pressure force applied by the first air knife assembly 120 to the top battery cell is small, resulting in a larger gap between adjacent battery cells. Conversely, if the airflow rate of the first air outlets 1222 is large, the positive air pressure force applied by the first air knife assembly 120 to the top battery cell is large, resulting in a smaller gap between adjacent battery cells. For different specifications of battery cells, for example, for smaller battery cells, the air flow rate of the first air outlet 1222 can be adjusted to be smaller, and for larger battery cells, the air flow rate of the first air outlet 1222 can be adjusted to be larger.
[0043] In this embodiment, for example, there are four first vents 1222. By coordinating the venting through these four first vents 1222, sufficient positive pressure can be applied to the top battery cell to ensure that the stacked battery cells do not loosen during the separation process. Of course, in other feasible embodiments, the number of first vents 1222 can also be two, six, or other numbers. This application does not limit the specific number of first vents 1222.
[0044] The aforementioned separation device 100, in response to the separation requirements of stacked battery cells, can control the airflow rate of the first air outlet 1222 through the first airflow valve to adjust the magnitude of the positive pressure applied to the top battery cell by the first air knife assembly 120, thereby maintaining the integrity of the stacked battery cells.
[0045] In one embodiment, see Figure 1 and Figure 3As shown, the second air knife assembly 130 includes a second air knife bracket 131 and a second air knife 132. The second air knife bracket 131 is disposed on the carrier 110. The second air knife bracket 131 is disposed on the carrier 110 by means of welding, screwing, etc., so as to realize the installation and fixation of the second air knife assembly 130 on the carrier 110. The second air knife 132 is disposed on the second air knife bracket 131, and the second air knife 132 is located on one side of the bearing space 111. The second air knife 132 is used to blow air toward the gap between two adjacent battery cells. If there is a gap between the second air knife 132 and the side of the battery cell, the airflow blown out by the second air knife 132 acts on the gap between the adjacent battery cells to form an air-insulating airflow layer between the two adjacent battery cells, so as to perform air flotation separation operation on the stacked battery cells.
[0046] As the number of stacked solar cells changes, the height of the stacked cells also changes. If air is blown at a position off-center from the height of the stacked cells, it will cause a significant difference in the separation gap between adjacent solar cells. Based on this, in one embodiment, see... Figure 1 and Figure 3 As shown, the second air knife 132 is movably disposed on the second air knife bracket 131, or the second air knife bracket 131 is movably disposed on the carrier 110. Thus, for stacked solar cells of different heights, the second air knife 132 or the second air knife bracket 131 can be moved to adjust the relative position of the second air knife 132 with respect to the height of the stacked solar cells, adjusting the second air knife 132 to the center position in the height direction of the stacked solar cells. The second air knife 132 can blow a gradual airflow into the gaps between adjacent solar cells, while under the positive pressure of the first air knife assembly 120, the separation gap between adjacent solar cells in the stack can be made more consistent.
[0047] Specifically, see Figure 1 and Figure 3 As shown, the second air knife bracket 131 is provided with a second sliding groove 1311. Preferably, the second sliding groove 1311 is integrally formed into the second air knife bracket 131 by injection molding, extrusion, or other methods to simplify the forming process of opening the second sliding groove 1311 in the second air knife bracket 131. The second air knife 132 has a second sliding post 1321, which is slidably disposed in the second sliding groove 1311, such as when the second sliding post 1321 is inserted into the second sliding groove 1311. Thus, by sliding the second sliding post 1321 within the second sliding groove 1311, the second sliding post 1321 drives the second air knife 132 to move, thereby changing the position of the second air knife 132 and adjusting the relative position of the second air knife 132 with respect to the height direction of the stacked battery cells.
[0048] It should be noted that the connection structure between the second air knife 132 and the second air knife support 131 can also be other structural forms that can realize the position movement of the second air knife 132, such as a slide rail and slide table module or a gear and rack module. This application does not limit the specific method of the connection structure between the second air knife 132 and the second air knife support 131.
[0049] Further, see Figure 1 and Figure 2 As shown, the second air knife assembly 130 also includes a second airflow valve. The second air knife 132 has multiple second air outlets 1322, and the second airflow valve is used to control the airflow rate of the second air outlets 1322. Exemplarily, the second air outlets 1322 are connected to an air passage, and the second airflow valve controls the airflow rate entering the second air outlets 1322. For example, during the separation of stacked solar cells, if the airflow rate of the second air outlets 1322 is small, the airflow rate applied to the side of the stacked solar cells by the second air knife assembly 130 is small, resulting in a smaller separation distance between adjacent solar cells. Conversely, if the airflow rate of the second air outlets 1322 is large, the airflow rate applied to the side of the stacked solar cells by the second air knife assembly 130 is large, resulting in a larger separation distance between adjacent solar cells. For example, for battery cells of different specifications, the air flow rate of the second air outlet 1322 can be adjusted to be smaller for stacked battery cells with smaller height, and larger for stacked battery cells with larger height.
[0050] In this embodiment, for example, there are four second air outlets 1322. By coordinating the airflow from these four outlets, sufficient airflow can be delivered to the sides of the stacked solar cells to form an airflow barrier between adjacent cells, thus performing air flotation separation on the stacked solar cells. Of course, in other feasible embodiments, the number of second air outlets 1322 can be two, six, or other numbers. This application does not limit the specific number of second air outlets 1322.
[0051] The separation device 100 described above can control the airflow of the second air outlet 1322 through the second airflow valve to adjust the amount of airflow applied to the side of the stacked battery cells by the second air knife assembly 130, so as to perform reliable air flotation separation operation on the stacked battery cells in order to meet the separation requirements of battery cells stacked at different heights.
[0052] In addition, this application also provides a solar cell transfer device, which includes a transfer device and a separation device 100 as described above. The transfer device is used for the flow of solar cells, such as by using conveyor rollers, conveyor belts, etc., to achieve the flow and transfer of solar cells. The separation device 100 is disposed on the transfer device. For example, if the separation device 100 is disposed at the sorting station of the transfer device, the separation device 100 can perform separation and sorting operations on the stacked solar cells after they are conveyed to the sorting station; or if the separation device 100 is disposed at the unloading station of the transfer device, the separation device 100 can perform separation and unloading operations on the stacked solar cells after they are conveyed to the unloading station; or if the separation device 100 is disposed at the packaging station of the transfer device, the separation device 100 can perform packaging and tidying operations on the stacked solar cells after they are conveyed to the packaging station.
[0053] The aforementioned cell transfer equipment can form an air flotation isolation layer between two adjacent cells through the first air knife assembly 120 and the second air knife assembly 130, thereby separating the stacked cells by air flotation. This avoids damage or scratches to the stacked cells during the separation process, and ensures good uniformity of the stacked cells during the unloading, receiving, and packaging processes.
[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
