Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments.

[0029] In the process of manufacturing solar cells, multiple steps such as electroplating, water washing and other treatments are required for photovoltaic cells. In the existing process of electroplating, water washing and other treatments for photovoltaic cells, in order to prevent the photovoltaic cells from shifting during the moving process, upper and lower driving rollers are generally arranged in the electroplating tank, water washing tank or various treatment tanks to clamp the photovoltaic cells, and the photovoltaic cells pass through between the upper and lower rollers. During this moving process, there is a risk of scratching the surface of the photovoltaic cells, especially the front side of the BC cell (Back Contact cell), because the entire front side is a matte surface and is more likely to be scratched. At the same time, because a certain clamping force is required for the upper and lower driving rollers to prevent the photovoltaic cells from shifting, there is a risk of fragmentation and hidden cracks in the photovoltaic cells.

[0030] In view of this, some embodiments of the present application provide a photovoltaic cell processing device, which can avoid the risks of scratching, fragmentation and hidden cracks of the photovoltaic cells while pushing the photovoltaic cells to move, thereby improving the yield of the photovoltaic cells.

[0031] The present application will be described in detail below through specific embodiments:

[0032] The photovoltaic cell processing device according to the embodiment of the present application, as Figure 1 - Figure 2 shown, the photovoltaic cell processing device includes a tank body 10, a first guiding member 20 and a second guiding member 30. The tank body 10 forms a receiving cavity 11 with an inlet 12 and an outlet 13. The inlet 12 and the outlet 13 are oppositely arranged. The first guiding member 20 and the second guiding member 30 are oppositely arranged in the receiving cavity 11. A conveying channel 40 is formed between the first guiding member 20 and the second guiding member 30. The conveying channel 40 is respectively communicated with the inlet 12 and the outlet 13. The first guiding member 20 and / or the second guiding member 30 is a liquid supply box body. A liquid spraying part is arranged on one side of the liquid supply box body close to the conveying channel 40. The liquid spraying part is used for spraying liquid on the photovoltaic cells so that the photovoltaic cells move along the conveying direction of the conveying channel 40.

[0033] It should be explained that both the first guiding member 20 and the second guiding member 30 can be liquid supply box bodies, or one of the first guiding member 20 and the second guiding member 30 is a liquid supply box body. The cavity of the liquid supply box body is used for storing liquid, and the cavity of the liquid supply box body is communicated with the liquid spraying part.

[0034] The photovoltaic cell processing device provided by the embodiment of the present application has the first guiding member 20 and the second guiding member 30 oppositely arranged in the accommodating cavity 11. A conveying channel 40 for conveying photovoltaic cells is formed between the first guiding member 20 and the second guiding member 30. The photovoltaic cells enter from the inlet 12 of the accommodating cavity 11, pass through the conveying channel 40, and then are output from the outlet 13 of the accommodating cavity 11. Since the first guiding member 20 and / or the second guiding member 30 is arranged as a liquid supply box body, the liquid spraying part of the liquid supply box body sprays liquid on the photovoltaic cells, thereby pushing the photovoltaic cells to move along the conveying channel 40. This way of pushing the photovoltaic cells by liquid spraying avoids the risks of scratching, fragmentation, and hidden cracks of the photovoltaic cells, thus improving the yield of the photovoltaic cells.

[0035] The liquid spraying part can have various implementation manners. In a possible implementation manner, the liquid spraying part includes a spraying surface and spraying ports arranged on the spraying surface. The spraying surface is inclined, and the end of the spraying surface close to the liquid supply box body is closer to the outlet 13 than the end of the spraying surface far from the liquid supply box body. Due to the inclined setting of the spraying surface, the liquid will form a specific angle and direction when spraying out from the spraying ports. Making the end of the spraying surface close to the liquid supply box body closer to the outlet 13 than the end of the spraying surface far from the liquid supply box body can make the liquid sprayed from the spraying ports incline towards the direction of the outlet 13 of the accommodating cavity 11, thereby pushing the photovoltaic cells to move along the conveying direction of the conveying channel 40. Spraying liquid through the spraying ports on the inclined spraying surface to push the photovoltaic cells to move has a simple structure and is easy to implement.

[0036] Specifically, there are multiple spraying surfaces, and the multiple spraying surfaces are arranged along the conveying direction of the conveying channel 40 and are parallel to each other. The multiple spraying surfaces can spray the photovoltaic cells simultaneously during the conveying process of the photovoltaic cells. Since the spraying surfaces are parallel, the spraying force and angle of the liquid are relatively consistent, so that the photovoltaic cells can be pushed with the same force and angle. In this way, the force on the photovoltaic cells is more uniform, enabling the photovoltaic cells to remain stable during movement. The multiple spraying surfaces working simultaneously can increase the moving speed of the photovoltaic cells during the advancing process and accelerate the processing speed of the photovoltaic cells. The parallel setting makes the control and adjustment of the parameters (such as spraying pressure, flow rate, etc.) of each spraying surface more convenient and unified, which is beneficial for the photovoltaic cells to move smoothly and stably along the conveying channel 40.

[0037] Specifically, the angle between the ejection surface and the conveying direction of the conveying channel 40 is set to 45°. The ejection ports on the ejection surface generate an impact force on the surface of the photovoltaic cell through this ejection angle, which can better push the photovoltaic cell to move along the conveying direction of the conveying channel 40. The 45° ejection angle can provide a relatively strong driving force while maintaining relatively good stability. At the same time, the ejected liquid will not generate a particularly large impact force on the photovoltaic cell to cause damage. The 45° ejection angle helps the liquid to better contact the photovoltaic cell, reducing liquid splashing and waste, and improving the utilization efficiency of the liquid. For the relatively narrow conveying channel 40 that meets the movement requirements of the photovoltaic cell, the 45° angle can better adapt to the layout of the conveying channel 40, reduce interference, effectively push the photovoltaic cell through, and can also more precisely control the movement position and speed of the photovoltaic cell. Of course, in other embodiments, the angle between the ejection surface and the conveying direction of the conveying channel 40 can also be set to other angles such as 30° or 60°, as long as the liquid ejected from the liquid ejection port can push the photovoltaic cell to move forward along the conveying direction of the conveying channel 40.

[0038] In another possible implementation manner of the liquid ejection part, the liquid ejection part includes a liquid ejection pipe. The liquid ejection pipe is inclined, and the liquid outlet end of the liquid ejection pipe is closer to the outlet 13 than the liquid inlet end of the liquid ejection pipe. In this way, the liquid ejection pipe ejects onto the photovoltaic cell in the direction of the outlet 13 of the accommodation cavity 11, pushing the photovoltaic cell to move along the conveying direction of the conveying channel 40. The liquid is ejected through the liquid ejection pipe. The inclined liquid ejection pipe enhances the ejection pressure, improves the ejection speed and efficiency, helps to increase the pressure potential energy of the liquid, so that the liquid ejected from the liquid outlet end has a greater pressure, improving the driving force on the photovoltaic cell. At the same time, the liquid ejection pipe has a certain guiding effect on the liquid, enabling the liquid to achieve a more sufficient pushing effect. Moreover, the liquid ejection pipe is convenient to arrange and can be better arranged in a limited space. The liquid ejection pipe can be installed to adapt to the structures of various different liquid supply boxes. Implementing ejection through the liquid ejection pipe also makes the installation and disassembly of the liquid ejection pipe more convenient, facilitating later maintenance and replacement operations.

[0039] Exemplarily, such as Figure 2As shown, the first guide member 20 is a liquid supply box, and the second guide member 30 is a roller assembly 32. The roller assembly 32 includes a plurality of first rollers 321 arranged in sequence along the conveying direction of the conveying channel 40. The plurality of first rollers 321 have the same rotation direction. The first rollers 321 provide stable support and guidance for the photovoltaic cell. The liquid spraying portion of the liquid supply box sprays liquid toward the photovoltaic cell, pushing the photovoltaic cell to move on the first rollers 321, ensuring that the photovoltaic cell moves on the first rollers 321 at a stable and uniform speed, preventing the photovoltaic cell from excessive lateral displacement during the conveying process. At the same time, the liquid sprayed by the liquid spraying portion of the liquid supply box will not cause abrasion to the photovoltaic cell. The rotation of the multiple first rollers 321 makes the transportation of the photovoltaic cells smoother and reduces energy consumption. The photovoltaic cells move on the first rollers 321 without the risk of fragmentation and hidden cracks. Since the first rollers 321 have a certain supporting force and can rotate freely, the stability of the photovoltaic cells can be better guaranteed. The multiple first rollers 321 arranged in sequence along the transportation direction can distribute the guiding force more evenly to avoid damage to the object caused by excessive local force. The roller assembly 32 includes multiple first rollers 321. When one of the rollers fails or is damaged, it is easier to repair or replace it separately without affecting the operation of the entire roller assembly 32.

[0040] Specifically, in one embodiment, the photovoltaic cell processing device is used for an electroplating process. At this time, the first roller 321 is set as a conductive roller, and the trough body 10 adopts an electroplating trough to electroplate photovoltaic cells (such as BC cells) that require single-sided electroplating. The BC cell has no electrode shielding on the front of the battery, thereby increasing the area of ​​the battery absorbing sunlight, thereby improving the conversion efficiency and generating more electricity. Therefore, the back of the BC battery is contacted with the conductive roller, and conduction is performed through the conductive roller. Since the entire front of the BC battery is velvet and is more easily scratched, the front of the BC battery is sprayed through the spray part of the liquid supply box to move it along the conveying direction of the conveying channel 40, without scratching the front of the BC battery. At the same time, the back of the BC battery can also be electroplated, making the photovoltaic cell processing device more applicable.

[0041] For example, Figure 3As shown, the first guide member 20 and the second guide member 30 are both liquid supply boxes, namely the first liquid supply box 21 and the second liquid supply box 31 respectively. A conveying channel 40 is formed between the first liquid supply box 21 and the second liquid supply box 31. The photovoltaic cell enters through the inlet 12 of the accommodating cavity 11, passes through the conveying channel 40, and is output through the outlet 13 of the accommodating cavity 11. Spray parts are respectively arranged on one side of the first liquid supply box 21 and the second liquid supply box 31 close to the conveying channel 40. The spray part includes a plurality of parallel spray surfaces, and the plurality of spray surfaces are arranged along the conveying direction of the conveying channel 40, so that the liquid sprayed by the first liquid supply box 21 and the second liquid supply box 31 fills the conveying channel 40. At the same time, the sprayed liquid acts on the photovoltaic cell, so that the photovoltaic cell moves stably along the conveying direction in the conveying channel 40, and the photovoltaic cell is processed.

[0042] In this embodiment, a first hollow baffle 41 and a second hollow baffle 42 are respectively arranged on opposite sides of the conveying channel 40. The first hollow baffle 41 and the second hollow baffle 42 are arranged along the conveying direction of the conveying channel 40 (only part of the structure of the second hollow baffle 42 is shown in the figure, and the actual structure is the same as that of the first hollow baffle 41). On the one hand, the first hollow baffle 41 and the second hollow baffle 42 can make the liquid in the conveying channel 40 flow out of the conveying channel 40 more slowly, ensuring the processing effect of the photovoltaic cell. In this way, the spraying speed of the spray part does not need to be too fast, reducing energy consumption. On the other hand, it can also prevent the photovoltaic cell from accidentally falling from both sides of the conveying channel 40, providing a certain protective effect, and can also play a guiding role in the conveying of the photovoltaic cell, making it move stably along the conveying direction of the conveying channel 40, reducing the possibility of deviating from the conveying track. At the same time, the hollow design is conducive to air circulation. For special processing processes, heat may be generated during the conveying process, and air can pass through the hollow part relatively freely, which can play a role in ventilation and heat dissipation, reducing the wind resistance generated during the conveying process. Operators can also observe the state of the photovoltaic cell during the conveying process through the hollow part, and discover abnormal situations in time. Compared with solid baffles, the hollow design can reduce the weight of the baffle, lower costs, and save materials at the same time.

[0043] Further, the second guide member 30 is located below the first guide member 20. A second roller 50 is provided between the second guide member 30 and the inlet 12, and a third roller 60 is provided between the second guide member 30 and the outlet 13. When the photovoltaic cell enters the conveying channel 40 from the entrance of the accommodation cavity 11, it first passes through the second roller 50, which can achieve a smoother entry process, reduce the impact and jamming between the photovoltaic cell and the conveying channel 40. The second roller 50 can play a buffering and guiding role, enabling the photovoltaic cell to smoothly enter the conveying channel 40, making the photovoltaic cell more stable during the conveying process and not prone to tilting or deviation. At the same time, when the photovoltaic cell leaves the conveying channel 40, it first passes through the third roller 60 and is smoothly output from the outlet 13 of the accommodation cavity 11 through the third roller 60, playing a certain buffering and guiding role. The second roller 50 and the third roller 60 together ensure the reliable movement of the photovoltaic cell in the conveying channel 40, and the settings of the second roller 50 and the third roller 60 make maintenance and adjustment more convenient. If the second roller 50 and the third roller 60 are worn or malfunction, they are easy to replace, ensuring the smooth entry and output of the photovoltaic cell and the stable conveying process of the photovoltaic cell, which helps to improve the conveying efficiency of the photovoltaic cell.

[0044] In this embodiment, a liquid storage tank 14 is formed at the bottom of the accommodation cavity 11. The liquid storage tank 14 is communicated with the liquid supply box body through a liquid inlet pipe 70. A liquid inlet pump 80 is connected in series on the liquid inlet pipe 70. In this way, the liquid in the liquid storage tank 14 can be sent to the liquid supply box body through the liquid inlet pump 80 and the liquid inlet pipe 70. The liquid supply box body sprays the photovoltaic cell through a liquid spraying part, and the sprayed liquid can also return to the liquid storage tank 14 at the same time, realizing the recycling of the liquid, improving the utilization rate of the liquid and reducing the cost. Moreover, the liquid storage tank 14 is located at the bottom of the accommodation cavity 11 as a buffer area. When the liquid inlet pump 80 is working, it can more stably supply liquid to the liquid supply box body, ensuring the continuity and stability of the liquid supply. The liquid storage tank 14 at the bottom of the accommodation cavity 11 can centrally collect the used liquid, facilitating the subsequent treatment, analysis or discharge control of the liquid. At the same time, the presence of the liquid inlet pump 80 can accurately control the flow rate and pressure of the liquid from the liquid storage tank 14 to the liquid supply box body according to actual needs. In the case of a malfunction or insufficient liquid supply in the liquid supply box body, the liquid in the liquid storage tank 14 can be used as a temporary emergency reserve to ensure the temporary normal operation of production or work.

[0045] When the photovoltaic cell processing device provided by the embodiment of the present application is in use, the photovoltaic cell enters the accommodation cavity 11 through the inlet of the accommodation cavity 11 via the second roller 50, and the photovoltaic cell moves along the conveying channel 40 between the first guiding member 20 and the second guiding member 30. Since the first guiding member 20 and / or the second guiding member 30 is arranged as a liquid supply box body, the liquid spraying part of the liquid supply box body sprays liquid on the photovoltaic cell, thereby pushing the photovoltaic cell to move along the conveying channel 40, and then output through the third roller 60 and the outlet 13 of the accommodation cavity 11. This way of pushing the photovoltaic cell to move by liquid spraying avoids the risks of scratching, fragmentation and hidden cracks of the photovoltaic cell, thereby improving the yield of the photovoltaic cell.
