Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0041] To better understand the embodiments of this application, the following is combined with... Figures 1 to 7 The embodiments of this application will be described in detail.

[0042] like Figures 1 to 7 As shown, this application provides a solar cell cleaning device 1, including a cleaning assembly 11, a liquid delivery assembly 12, and a drain outlet 13. The cleaning assembly 11 includes a base plate 111 and a side plate 112, with the side plate 112 surrounding the base plate 111 to form a cleaning chamber 113. The liquid delivery assembly 12 includes a first delivery pipe 121, a second delivery pipe 122, and a mixing component 123. The first delivery pipe 121 and the second delivery pipe 122 are used to deliver pure water and cleaning agent, respectively. One end of the mixing component 123 is connected to the first delivery pipe 121 and the second delivery pipe 122, and the other end is connected to the cleaning chamber 113. The drain outlet 13 is located on the base plate 111 and is used to drain the liquid from the cleaning chamber 113.

[0043] The cleaning assembly 11 includes a base plate 111 and a side plate 112. The base plate 111 and the side plate 112 are made of corrosion-resistant material or the inner sidewalls of the base plate 111 and the side plate 112 are coated or pasted with corrosion-resistant material to prevent the cleaning agent or residual chemical reagents in the solar cell 2 from corroding the cleaning assembly 11 and to improve the service life of the cleaning assembly 11.

[0044] Side plates 112 surround the base plate 111 to form a cleaning chamber 113. Specifically, the cleaning chamber 113 can be a cuboid structure or a cylindrical structure; this embodiment does not limit this. In some embodiments, the solar cell 2 is immersed in the cleaning chamber 123, and the liquid in the cleaning chamber 123 washes away impurities on its surface. In other embodiments, the solar cell 2 can move within the cleaning chamber 123 to increase the cleaning effect. It should be noted that the solar cell 2 can be fixed in the cleaning chamber 123 by clamping mechanisms such as claws, magnetic suction components, and negative pressure adsorption components, or it can be placed in the cleaning chamber 123 by a bracket such as a flower basket; this embodiment does not limit this. By surrounding the base plate 111 with side plates 112 to form the cleaning chamber 113, the sealing of the cleaning chamber 113 can be ensured, which can both ensure the cleaning effect of the solar cell 2 and prevent the cleaning agent from overflowing and polluting the external environment.

[0045] The infusion assembly 12 refers to the component that delivers pure water and cleaning agent to the cleaning chamber 113. The infusion assembly 12 includes a first delivery pipe 121, a second delivery pipe 122, and a mixing component 123. The cross-sections of the first delivery pipe 121 and the second delivery pipe 122 can be regular shapes such as square or circular, or irregular shapes composed of straight lines and / or curves; this embodiment does not impose such limitations. By setting the first delivery pipe 121 and the second delivery pipe 122 to deliver pure water and cleaning agent respectively, it is convenient to achieve precise delivery and adjustment of the ratio of pure water to cleaning agent, thereby improving the applicability of the solar cell cleaning device 1.

[0046] The mixing component 123 refers to a component used to mix pure water and cleaning agent. Specifically, in some embodiments, the mixing component 123 includes multiple staggered guide vanes. When pure water and cleaning agent are input into the mixing component 123 through the first delivery pipe 121 and the second delivery pipe 122, they are subjected to multiple cross-flows, shearing, and mixing under the action of the guide vanes, thereby achieving uniform mixing of the two. In other embodiments, the mixing component 123 includes a stirrer. After pure water and cleaning agent are input into the mixing component through the first delivery pipe 121 and the second delivery pipe 122, the stirrer rotates to stir the pure water and cleaning agent, ensuring thorough mixing. It should be noted that the mixing component 123 can also be other components capable of liquid mixing, and this application embodiment does not limit this.

[0047] One end of the mixing component 123 is connected to the first conveying pipe 121 and the second conveying pipe 122, and can mix the pure water and cleaning agent conveyed from the first conveying pipe 121 and the second conveying pipe 122 evenly, so that the mixed liquid has better cleaning performance; the other end of the mixing component 123 is connected to the cleaning chamber 113 to convey the mixed liquid to the cleaning chamber 113 for cleaning the solar cell 2.

[0048] The drain port 13 is located on the base plate 111, which can drain the liquid in the cleaning chamber 113 in a timely manner. This facilitates the collection and treatment of the liquid after use, and allows for the rapid replacement of the liquid in the cleaning chamber 123, thereby improving the cleaning quality and efficiency of the solar cell 2.

[0049] When the pure water and cleaning agent in the cleaning chamber 123 are not mixed evenly, on the one hand, areas with excessively high cleaning agent concentration will waste the cleaning agent, while areas with excessively low cleaning agent concentration will not be able to completely remove contaminants, ultimately resulting in differences in the cleaning effect of the solar cells 2, leading to large differences in the quality of solar cells 2 produced under the same process parameters; on the other hand, the undissolved cleaning agent will settle at the bottom of the tank, not only wasting the agent, but also becoming a new source of pollution.

[0050] By setting up a mixing component 123, one end of the mixing component 123 is connected to the first conveying pipe 121 and the second conveying pipe 122, and the other end is connected to the cleaning chamber 113. The mixing component 123 mixes the pure water and cleaning agent conveyed by the first conveying pipe 121 and the second conveying pipe 122 and then inputs them into the cleaning chamber 113, ensuring that the pure water and cleaning agent entering the cleaning chamber 113 can be fully mixed, thereby improving the cleaning effect of the solar cell 2 while reducing production costs.

[0051] like Figures 1 to 3 As shown in Figure 7, in some embodiments, the mixing component 123 includes an overflow pipe 1231 and an overflow hole 1232 spaced apart from the overflow pipe 1231, the overflow hole 1232 being connected to the cleaning chamber 113.

[0052] The mixing component 123 includes an overflow pipe 1231 and overflow holes 1232 spaced apart from the overflow pipe 1231. The first conveying pipe 121 and the second conveying pipe 122 convey pure water and cleaning agent into the overflow pipe 1231. Subsequently, the pure water and cleaning agent in the overflow pipe 1231 are conveyed into the cleaning chamber 113 through the overflow hole 1232.

[0053] By providing overflow holes 1232 at intervals on the overflow pipe 1231, on the one hand, pure water and cleaning agent can be evenly distributed into the cleaning chamber 113 through the overflow holes 1232; on the other hand, the pressure of pure water overflowing from the overflow holes 1232 can be used to fully mix the pure water and cleaning agent, thereby improving the cleaning effect of the solar cell 2.

[0054] By setting an overflow pipe 1231 and an overflow hole 1232, and connecting one end of the overflow pipe 1231 to the first conveying pipe 121 and the second conveying pipe 122, the first conveying pipe 121 can convey pure water and cleaning agent into the overflow pipe 1231. When the pure water and cleaning agent overflow from the overflow hole 1232 into the cleaning chamber 113, the pressure of the pure water can be used to fully mix the cleaning agent and pure water. While achieving uniform mixing of pure water and cleaning agent, the structure of the mixing component 123 is simple and occupies little space.

[0055] like Figure 3 As shown, in some embodiments, the mixing component 123 further includes a mixing pipe 1233, one end of which is connected to the first conveying pipe 121 and the second conveying pipe 122, and the other end is connected to the overflow pipe 1231.

[0056] One end of the mixing pipe 1233 is connected to the first conveying pipe 121 and the second conveying pipe 122 to receive and mix the pure water and cleaning agent delivered from the first and second conveying pipes 121 and the second conveying pipe 122. The other end of the mixing pipe 1233 is connected to the overflow pipe 1231 to deliver the mixed pure water and cleaning agent to the overflow pipe 1231, and finally overflow into the cleaning chamber 113. Specifically, the mixing pipe 1233 may include a guide vane to achieve uniform mixing of pure water and cleaning agent through the guiding effect of the guide vane. The mixing pipe 1233 may also include a stirrer to stir the pure water and cleaning agent through the rotation of the stirrer, so that the two are fully mixed.

[0057] By setting up the mixing pipe 1233, the pure water and cleaning agent delivered from the first delivery pipe 121 and the second delivery pipe 122 are initially mixed to ensure that the two liquids are mixed for the first time before entering the overflow pipe 1231. Subsequently, when the liquid overflows from the overflow hole 1232 to the cleaning chamber 113, it can be further mixed to make the mixture more uniform, thereby improving the cleaning effect of the solar cell 2.

[0058] In some embodiments, the mixing tube 1233 includes a mixing section, which is a baffle plate disposed on the inner wall of the mixing tube 1233, or a spiral component disposed within the mixing tube 1233.

[0059] Specifically, in some embodiments, the mixing section is a baffle plate disposed on the inner wall of the mixing pipe 1233. The baffle plate is plate-shaped or blade-shaped. When pure water and cleaning agent flow through the mixing pipe 1233, the baffle plate changes the flow direction of the liquid, generating turbulence, thereby achieving mixing of pure water and cleaning agent. In other embodiments, the mixing section is a spiral component disposed inside the mixing pipe 1233. When pure water and cleaning agent flow through the spiral component, the spiral component guides both to flow along the spiral direction, thereby increasing the flow path and mixing time of pure water and cleaning agent, and thus improving the mixing uniformity of pure water and cleaning agent.

[0060] like Figure 6 and 7 As shown, in some embodiments, the overflow pipe 1231 is integrated into the base plate 111, or the overflow pipe 1231 extends into the cleaning chamber 113, and the distance between the overflow pipe 1231 and the base plate 111 is less than or equal to 20cm.

[0061] Specifically, in some embodiments, the overflow pipe 1231 is integrated into the base plate 111, meaning the overflow pipe 1231 is formed by a through hole on the base plate 111. This simplifies the structure of the solar cell cleaning device 1 and improves the space utilization of the cleaning chamber 113. In other embodiments, the overflow pipe 1231 extends into the cleaning chamber 113, facilitating its disassembly and replacement. It should be noted that in these embodiments, the distance between the overflow pipe 1231 and the base plate 111 is less than or equal to 20 cm. This ensures effective space for the solar cells 2 within the cleaning chamber 113 and prevents interference between the overflow pipe 1231 and the solar cells 2, thus affecting the production quality of the solar cells 2.

[0062] like Figures 1 to 6 As shown, in some embodiments, the solar cell cleaning device 1 further includes a liquid storage device 14 connected to one end of the second delivery pipe 122 away from the mixing component 123, and the liquid delivery assembly 12 includes a regulating valve 124 and a one-way valve 125. The regulating valve 124 is located in the second delivery pipe 122; the one-way valve 125 is located in the second delivery pipe 122 and downstream of the regulating valve 124.

[0063] The liquid storage component 14 is a component used to store cleaning agent. The liquid storage component 14 is connected to the end of the second delivery pipe 122 away from the mixing component 123, that is, the liquid storage component 14 and the mixing component 123 are connected through the second delivery pipe 122 to ensure that the mixing component 123 has a sufficient supply of cleaning agent.

[0064] The infusion assembly 12 includes a regulating valve 124 and a one-way valve 125. The regulating valve 124 is located in the second delivery pipe 122 and is used to control the opening of the second delivery pipe 122, thereby regulating the amount of cleaning agent input to the mixing component 123. This allows for precise control of the cleaning agent flow rate, ensuring the supply of cleaning agent meets cleaning requirements; furthermore, it can adapt to different production processes, improving the applicability of the solar cell cleaning device 1. Specifically, the regulating valve 124 can be a manual valve, a pneumatic valve, or a solenoid valve; this embodiment does not impose any limitations on this.

[0065] A one-way valve 125 is installed in the second delivery pipe 122 downstream of the regulating valve 124 to ensure that the cleaning agent can only flow from the liquid storage unit 14 to the mixing unit 123, preventing the cleaning agent and pure water from flowing back into the liquid storage unit 14 and contaminating the cleaning agent in the liquid storage unit 14.

[0066] like Figures 1 to 3 As shown, in some embodiments, the solar cell cleaning device 1 further includes a detection element 15 and a control element 16. The detection element 15 is disposed in the cleaning chamber 113 and is used to detect the concentration of the cleaning agent; the control element 16 is communicatively connected to the detection element 15 and the regulating valve 124 to adjust the opening degree of the regulating valve 124 according to the detection result of the detection element 15.

[0067] The detection component 15 refers to the component used to detect the concentration of the cleaning agent in the cleaning chamber 113. By placing the detection component 15 inside the cleaning chamber 113, the detection component 15 can directly contact the cleaning liquid, thereby enabling real-time detection of the concentration of the cleaning agent in the cleaning liquid. This ensures that the concentration of the cleaning liquid meets the process requirements, saving costs while guaranteeing the cleaning effect of the solar cell 2.

[0068] The control element 16 is communicatively connected to the detection element 15 and the regulating valve 124. Specifically, the communication connection between the control element 16 and the detection element 15 and the regulating valve 124 can be achieved through wireless communication such as a wireless network, or through wired communication such as a cable; this application implements it without limitation.

[0069] The control unit 16 can adjust the opening of the regulating valve 124 based on the detection results of the detection unit 15. That is, the control unit 16 can acquire the detection results of the detection unit 15 in real time and regulate the regulating valve 124. For example, when the cleaning agent concentration detected by the detection unit 15 is lower than a preset range, the control unit 16 controls the regulating valve 124 to increase its opening, thereby increasing the amount of cleaning agent added; conversely, when the cleaning agent concentration detected by the detection unit 15 is higher than the preset range, the control unit 16 controls the regulating valve 124 to decrease its opening, thereby reducing the amount of cleaning agent added. In this way, real-time regulation of the cleaning agent concentration within the cleaning chamber 113 can be achieved, ensuring the cleaning effect of the solar cell 2 while reducing the amount of cleaning agent used and lowering production costs.

[0070] like Figures 1 to 3 As shown in Figures 6 and 7, in some embodiments, the detection element 15 is a conductivity detection element.

[0071] A conductivity detector is a component used to detect the conductivity of a liquid. In a cleaning solution, the cleaning agent ionizes into ions, which increase the liquid's conductivity. Therefore, by using a conductivity detector to measure the conductivity of the cleaning solution, the concentration of the cleaning agent within the cleaning chamber 113 can be indirectly reflected. By setting the detector 15 as a conductivity detector, the concentration of the cleaning agent can be detected promptly and efficiently, ensuring the control accuracy of the control component 16.

[0072] It should be noted that the detection element 15 can also detect the concentration of the cleaning agent by detecting the optical properties such as the refractive index of the liquid in the cleaning chamber 113, or by detecting the acidity or alkalinity of the liquid in the cleaning chamber 113. This application embodiment does not limit this.

[0073] like Figures 1 to 4 As shown in Figures 6 and 7, in some embodiments, the cleaning component 11 is a slow-lifting groove, and the solar cell cleaning device 1 also includes a lifting member 17 for driving the solar cell 2 to move slowly within the slow-lifting groove.

[0074] The lifting member 17 can be a robotic arm that slowly moves the solar cell 2 within the cleaning chamber 113 by gripping it. Alternatively, the lifting member 17 can be a lifting device installed within the cleaning chamber 113, which achieves the slow lifting function of the solar cell 2 by slowly moving the lifting member 17 within the cleaning chamber 113.

[0075] By setting the slow lifting component 17 to drive the solar cell 2 to move slowly in the slow lifting groove, on the one hand, it can be ensured that the solar cell 2 is evenly covered by the cleaning liquid throughout the cleaning process; on the other hand, the slow lifting component 17 can achieve slow and even movement of the solar cell 2, avoiding liquid splashing and bubble generation caused by rapid movement, thereby reducing the residue of dirt on the surface of the solar cell 2 and improving the cleaning effect of the solar cell 2.

[0076] like Figure 4 , 6 As shown in Figures 7 and 8, in some embodiments, the lifting member 17 includes a mounting member 171 and a flower basket 172. The mounting member 171 is movably disposed in the cleaning chamber 113; the flower basket 172 is disposed on the mounting member 171, and the solar cell 2 is placed in the flower basket 172.

[0077] Mounting member 171 is the main support structure of lifting member 17. Mounting member 171 is movably arranged in cleaning chamber 113. Specifically, mounting member 171 can be movably arranged in cleaning chamber 113 through mechanisms such as guide rail slider. Mounting member 171 can also be a component with telescopic function, which can be movably arranged in cleaning chamber 113 by extending and retracting. This application embodiment does not limit this.

[0078] The basket 172 is a container for placing the solar cell 2. The basket 172 can be a mesh or frame structure to ensure that the cleaning fluid can evenly contact all surfaces of the solar cell 2. The basket 172 is set on the mounting member 171 to ensure that the basket 172 can move with the mounting member 171, thereby realizing the slow lifting function of the solar cell 2 in the cleaning chamber 113.

[0079] The solar cell 2 is placed inside the flower basket 172. Specifically, in some embodiments, the flower basket is provided with a slot in which the solar cell 2 is secured; in other embodiments, the flower basket 172 is provided with a holding component, which holds and fixes the solar cell 2 by means of mechanical grippers, magnetic suction components, or negative pressure adsorption components.

[0080] The flower basket 172 is disposed on the mounting part 171. Specifically, the flower basket 172 and the mounting part 171 are detachably connected so that the flower basket 172 and the solar cell 2 can be removed from the mounting part 171 after the cleaning process of the solar cell 2 is completed, so that the flower basket 172 and the solar cell 2 can be transported to the subsequent process.

[0081] In some embodiments, the lifting member 17 further includes a driving member 173, which is disposed outside the cleaning chamber 113 and is drivenly connected to the mounting member 171.

[0082] The drive component 173 is located outside the cleaning chamber 113. In this way, the drive component 173 can be prevented from occupying the space of the cleaning chamber 113, and the cleaning fluid in the cleaning chamber 113 can be prevented from corroding the drive component 173, thereby improving the service life of the drive component 173.

[0083] The driving component 173 is driven to connect with the mounting component 171, that is, the output end of the driving component 173 is connected to the mounting component 171, thereby driving the mounting component 171 to move slowly within the cleaning chamber 113, thus realizing the slow lifting function of the solar cell 2. Specifically, the driving component 173 can be a battery, or a cylinder, hydraulic cylinder, etc., and this application embodiment does not limit this.

[0084] Specifically, such as Figures 1 to 7 As shown, during the feeding process, the solar cells are fed into the basket 172, which is placed inside the cleaning chamber 113.

[0085] Subsequently, the first conveying pipe 121 and the second conveying pipe 122 respectively convey pure water and cleaning agent to the overflow pipe 1231. The pure water and cleaning agent in the overflow pipe 1231 are mixed under the action of pure water pressure and overflow from the overflow hole 1232 into the cleaning chamber 113. When the liquid in the cleaning chamber 113 reaches the preset depth, the drive component 173 drives the mounting component 171 to rise slowly, and drives the flower basket 172 and the solar cell 2 to rise slowly, completing the cleaning process of the solar cell 2.

[0086] After cleaning, the flower basket 172 and solar cell 2 are moved from the cleaning process to the next process to complete the subsequent operations.

[0087] 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.

[0088] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
