Description

Technical Field

[0001] This application belongs to the technical field of scope, specifically a wet cleaning machine for precise removal of BSG from the back of BC batteries. Background Technology

[0002] The precise wet cleaning of the back side of BC batteries is mainly used to remove the borosilicate glass (BSG) layer deposited on the back side of the battery with high precision and low damage during the production process of BC (back contact) batteries. It also simultaneously completes cleaning and waste liquid collection to ensure the passivation effect and photoelectric conversion efficiency of the battery back side.

[0003] Existing BC battery back-side cleaning equipment mostly adopts a split design, with each functional module relatively independent. This leads to frequent transfer of battery cells between different workstations, increasing the breakage rate and surface contamination risk, and making it difficult to achieve precise control of the cleaning angle. Furthermore, traditional clamping methods are mostly rigid contact or complex pneumatic control, which easily cause microcracks or clamping marks on the battery cells and are incompatible with various wafer sizes. In addition, when using hydrofluoric acid for etching, existing equipment lacks effective front-side spill protection measures, allowing cleaning fluid to easily climb onto the front of the battery and cause accidental corrosion, severely impacting product yield. Waste liquid generated during the cleaning process often cannot be collected in time, resulting in residual chemicals on the back of the battery and causing secondary defects. Therefore, existing equipment generally suffers from low integration, poor cleaning accuracy, high breakage rate, and weak process compatibility.

[0004] In summary, existing cleaning equipment lacks a solution that can highly integrate clamping and positioning, tilt adjustment, precise etching, and waste liquid management, resulting in poor coordination of the cleaning process and making it difficult to meet the high-efficiency, high-quality cleaning requirements of the BSG layer on the back of BC batteries. Summary of the Invention

[0005] The purpose of this application is to provide an integrated machine for precise wet cleaning of the back of BC batteries to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: A BC battery back-side BSG wet cleaning integrated machine includes a working frame, a clamping frame provided on the inner surface of the working frame, an upper support shell fixedly connected to the upper outer surface of the working frame, a tilt adjustment mechanism fixedly installed on the upper support shell, a precision cleaning mechanism fixedly connected to the outer surface of the working frame away from the upper support shell, a flushing pump fixedly connected to the side surface of the working frame, an adjustment shaft provided on the outer surface of the clamping frame, the adjustment shaft movably connected to the inner groove of the working frame, a clamping block movably connected to the inner surface of the clamping frame, a rocker arm movably connected to the inner surface of the clamping frame corresponding to the clamping block, a force-bearing wheel rotatably connected to the outer surface of the clamping frame away from the adjustment shaft, a rack fixedly connected to the outer surface of the clamping frame, and an adjustment plate provided on the outer surface of the other end of the rack.

[0007] By adopting the above technical solution, and setting the working frame as an integrated cleaning carrier with a clamping frame on its inner surface, stable positioning of BC batteries during the cleaning process is achieved. The clamping frame is movably connected to the working frame via an adjusting shaft, and together with the clamping blocks, rocker arms, and force-bearing wheels, forms a linkage clamping structure that automatically and adaptively clamps the BC battery after insertion, requiring no additional manual intervention and improving clamping efficiency. The design of the rack and pinion mechanism and the adjusting plate allows for flexible adjustment of the clamping span according to the size specifications of the BC battery, adapting to the production needs of BC batteries of different sizes and enhancing the versatility of the equipment. The integrated layout of the upper support shell, tilt adjustment mechanism, precision cleaning mechanism, and flushing pump reduces material transfer losses between processes and lowers the risk of scratches on the BC battery surface.

[0008] In a preferred embodiment, the tilt adjustment mechanism includes a transmission belt and a telescopic motor. The telescopic motor is fixedly connected to the inner surface of the upper support housing, and the outer surface of the output end of the telescopic motor is fixedly connected to the adjustment shaft. The transmission belt is fixedly connected to the inner surface of the upper support housing.

[0009] By adopting the above technical solution, the tilt adjustment mechanism directly drives the adjustment shaft via a telescopic motor, which can precisely control the tilt angle of the clamping frame, creating an angle on the back of the BC battery that facilitates the flow of cleaning fluid. The transmission belt ensures stable power transmission, avoiding uneven force on the clamping frame caused by single-point drive, ensuring that the BC battery remains horizontal during tilting, preventing local accumulation or uneven flow of cleaning fluid, and providing a foundation for subsequent uniform etching.

[0010] In a preferred embodiment, a winding machine is fixedly connected to the outer surface of the transmission belt, and the outer surface of the output end of the winding machine is fixedly connected to the force-bearing wheel.

[0011] By adopting the above technical solution, a winding machine is fixed on the transmission belt and connected to the force-bearing wheel. The winding and unwinding actions of the winding machine can independently control the lifting and lowering of the clamping frame at the end away from the adjusting shaft. Combined with the drive of the telescopic motor, multi-angle flipping adjustment of the clamping frame is achieved. For example, after cleaning, one side of the clamping frame can be lifted by the winding machine so that the back of the BC battery faces the precision cleaning mechanism. Double-sided cleaning switching can be completed without manually flipping the battery, further improving the level of automation.

[0012] In a preferred embodiment, an air pump is fixedly connected to the lower surface of the upper support shell, and air nozzles are provided on the outer surfaces of both ends of the air pump. A reference plate is fixedly connected to the inner outer surface of the air nozzles.

[0013] By employing the above technical solution, an air pump located on the lower surface of the upper support casing injects airflow through nozzles onto the sides of the BC battery, forming a dynamic air curtain protective layer at the battery edge. This design effectively prevents cleaning fluid from penetrating to the front of the BC battery, avoiding corrosion of the non-etched areas on the front by hydrofluoric acid, and is particularly suitable for BC battery structures where the BSG layer exists only on the back. The reference plate provides a positioning reference for the nozzles, ensuring the accuracy of the air curtain coverage.

[0014] In a preferred embodiment, a water guide pipe is fixedly connected to the lower surface of the upper support shell, and compensation nozzles are provided on the outer surfaces of both ends of the water guide pipe. The outer surfaces of the compensation nozzles are fixedly connected to the outer surface of the reference plate on the side away from the air nozzle.

[0015] By adopting the above technical solution, the compensating spray nozzle connected to the water guide pipe is fixed on the side of the reference plate. It can replenish the water film to the edge of the BC battery at the same time as the air curtain is formed. The water film pre-wets the edge of the battery, reduces the surface tension of the cleaning fluid, and prevents the cleaning fluid from climbing to the front due to capillary action. The air curtain further blocks the diffusion path of the cleaning fluid.

[0016] In a preferred embodiment, a flushing pipe is fixedly connected to the lower outer surface of the upper support housing, a front and rear guide rail is fixedly connected to the inner surface of the upper support housing, a left and right guide rail is provided on the outer surface of the output end of the front and rear guide rail, and an etching nozzle is provided on the outer surface of the output end of the left and right guide rail.

[0017] By adopting the above technical solution, the flushing pipe, combined with front-to-back guide rails and left-to-right guide rails, achieves precise positioning of the etching nozzles in a two-dimensional plane. The front-to-back guide rails are responsible for adjusting the distance between the nozzles and the BC battery, while the left-to-right guide rails enable scanning flushing along the battery edge. Together, these two systems ensure that the etching nozzles cover the entire BSG area on the back of the BC battery, avoiding cleaning blind spots. The high-flow-rate flushing pipe quickly removes waste liquid generated by the etching reaction, preventing reaction products from depositing on the battery surface and causing secondary pollution, thus improving cleaning uniformity.

[0018] In a preferred embodiment, a six-axis robotic arm is fixedly connected to the outer surface of the output end of the precision cleaning mechanism, and an etching and rinsing nozzle is fixedly connected to the outer surface of the output end of the six-axis robotic arm.

[0019] By adopting the above technical solution, the precision cleaning mechanism uses a six-axis robotic arm to drive the etching and rinsing nozzle, overcoming the movement limitations of traditional fixed nozzles. The six-axis robotic arm can achieve multi-degree-of-freedom motion, including X / Y / Z-axis translation and rotation around the axis, enabling the etching and rinsing nozzle to precisely target micro-defects on the back of the BC battery for targeted and quantitative rinsing.

[0020] In a preferred embodiment, the flushing pump includes a water pump and a hydrofluoric acid water pump. The outer surface of the output end of the water pump is fixedly connected to the water guide pipe and the flushing pipe. The outer surfaces of the two independent output ends of the hydrofluoric acid water pump are respectively fixedly connected to the etching nozzle and the etching flushing nozzle.

[0021] By adopting the above technical solution, the flushing pump uses a dual-pump independent supply design with a water pump and a hydrofluoric acid pump, achieving pipeline isolation between pure water and hydrofluoric acid. The water pump is dedicated to supplying pure water to the water guide pipe and flushing pipe, ensuring no chemical reagent residue during the pre-rinse and final rinsing stages; the two independent output ends of the hydrofluoric acid pump are connected to the etching nozzle and the etching flushing nozzle respectively, facilitating independent control.

[0022] In a preferred embodiment, a water storage box is fixedly connected to the inner surface of the middle of the working frame. The water storage box is made of polytetrafluoroethylene (PTFE), and the hydrofluoric acid water pump is also made of PTFE.

[0023] By adopting the above technical solution, the water storage box inside the working frame is made of polytetrafluoroethylene (PTFE), whose resistance to hydrofluoric acid corrosion ensures long-term stability. At the same time, the surface inertness of PTFE reduces waste liquid residue and facilitates cleaning. The delivery pipeline of the hydrofluoric acid pump is also made of PTFE, which eliminates the risk of hydrofluoric acid leakage at the source and improves equipment safety.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: 1. A stable cleaning platform is constructed through the cooperation of the working frame and the embedded clamping frame. The clamping frame is movably connected to the inner groove of the working frame via an adjusting shaft. Combined with the lever linkage clamping mechanism formed by the clamping blocks and the rocker arm, it can automatically complete adaptive locking after the BC battery is inserted. Compared with traditional threaded fastening or pneumatic clamping, it greatly simplifies the clamping steps, effectively avoids microcrack damage to the surface of the battery cells during the clamping process, and improves loading and unloading efficiency. Second, by integrating the tilt adjustment mechanism, precision cleaning mechanism and flushing pump on the same working frame, the limitations of isolated operation of each station in traditional cleaning equipment are broken. In particular, the side connection between the flushing pump and the working frame, together with the support of the supporting shell, enables the cleaning medium to act efficiently on the back of the BC battery in a closed or semi-closed space, reducing the risk of secondary pollution in the process flow and significantly shortening the production cycle. Third, the force-bearing wheel at the end of the clamping frame, along with the rack and adjusting plate on its outer surface, gives the equipment excellent process compatibility. The extension length of the rack can be adjusted by moving the adjusting plate, thereby changing the effective clamping span of the clamping frame to accommodate different BC battery sizes. The force-bearing wheel provides a fulcrum for the independent unilateral lifting of the clamping frame (which can be controlled by an external mechanism), and also provides a structural foundation for multi-angle flipping of the BC battery during the cleaning process, enhancing the equipment's adaptability to different cleaning process routes.

[0028] Reference Figure 1-10 , Example: A precision wet cleaning machine for removing BSG from the back of BC batteries includes a working frame 100, a clamping frame 200 on the inner surface of the working frame 100, an upper support shell 300 fixedly connected to the upper outer surface of the working frame 100, a tilt adjustment mechanism 400 fixedly installed on the upper support shell 300, a precision cleaning mechanism 500 fixedly connected to the outer surface of the working frame 100 away from the upper support shell 300, and a side surface of the working frame 100 fixedly connected to... The flushing pump 600 has an adjusting shaft 201 on the outer surface of the clamping frame 200, which is movably connected to the inner groove of the working frame 100. A clamping block 202 is movably connected to the inner surface of the clamping frame 200. A rocker arm 203 is movably connected to the inner surface of the clamping frame 200 corresponding to the clamping block 202. A force-bearing wheel 204 is rotatably connected to the outer surface of the clamping frame 200 away from the adjusting shaft 201. A rack 205 is fixedly connected to the outer surface of the clamping frame 200. An adjusting plate 206 is provided on the outer surface of the other end of the rack 205.

[0029] By setting the working frame 100 as an integrated cleaning carrier and configuring the clamping frame 200 on its inner surface, stable positioning of BC batteries is achieved during the cleaning process. The clamping frame 200 is movably connected to the working frame 100 via the adjusting shaft 201. Together with the clamping block 202, the rocker arm 203, and the force-bearing wheel 204, the linked clamping structure can automatically complete adaptive clamping after the BC battery is inserted, without additional manual intervention, thus improving clamping efficiency. The cooperative design of the rack 205 and the adjusting plate 206 allows for flexible adjustment of the clamping span according to the size specifications of the BC battery, adapting to the production needs of BC batteries of different sizes and enhancing the versatility of the equipment. The integrated layout of the upper support shell 300, the tilt adjustment mechanism 400, the precision cleaning mechanism 500, and the flushing pump 600 reduces material transfer losses between processes and lowers the risk of scratches on the BC battery surface.

[0030] The tilt adjustment mechanism 400 includes a transmission belt 401 and a telescopic motor 402. The telescopic motor 402 is fixedly connected to the inner surface of the upper support housing 300. The outer surface of the output end of the telescopic motor 402 is fixedly connected to the adjustment shaft 201. The transmission belt 401 is fixedly connected to the inner surface of the upper support housing 300.

[0031] The tilt adjustment mechanism 400 directly drives the adjustment shaft 201 via the telescopic motor 402, which can precisely control the tilt angle of the clamping frame 200, creating an angle on the back of the BC battery that facilitates the flow of cleaning fluid. The transmission belt 401 ensures stable power transmission, avoiding uneven force on the clamping frame 200 caused by single-point drive, ensuring that the BC battery remains horizontal during tilting, preventing local accumulation or uneven flow of cleaning fluid, and providing a foundation for subsequent uniform etching.

[0032] A winding machine 403 is fixedly connected to the outer surface of the transmission belt 401, and the outer surface of the output end of the winding machine 403 is fixedly connected to the force-bearing wheel 204.

[0033] A winding machine 403 is fixed on the drive belt 401 and connected to the force-bearing wheel 204. The winding and unwinding actions of the winding machine 403 can independently control the lifting and lowering of the end of the clamping frame 200 away from the adjusting shaft 201. With the drive of the telescopic motor 402, multi-angle flipping adjustment of the clamping frame 200 is realized. For example, after cleaning, one side of the clamping frame 200 can be lifted by the winding machine 403 so that the back of the BC battery faces the precision cleaning mechanism 500. Double-sided cleaning switching can be completed without manual flipping of the battery, further improving the degree of automation.

[0034] An air pump 312 is fixedly connected to the lower surface of the upper support housing 300. Air nozzles 310 are provided on the outer surfaces of both ends of the air pump 312. A reference plate 311 is fixedly connected to the inner outer surface of the air nozzles 310.

[0035] An air pump 312, located on the lower surface of the upper support housing 300, sprays airflow onto the sides of the BC battery via an air nozzle 310, forming a dynamic air curtain protective layer at the battery edge. This design effectively prevents cleaning fluid from penetrating the front of the BC battery, avoiding corrosion of the non-etched areas by hydrofluoric acid, and is particularly suitable for BC battery structures where the BSG borosilicate glass layer exists only on the back. A reference plate 311 provides a positioning reference for the air nozzle 310, ensuring the accuracy of the air curtain coverage.

[0036] A water guide pipe 320 is fixedly connected to the lower surface of the upper support shell 300. Compensation spray nozzles 321 are provided on the outer surfaces of both ends of the water guide pipe 320. The outer surfaces of the compensation spray nozzles 321 are fixedly connected to the outer surface of the reference plate 311 on the side away from the air nozzle 310.

[0037] The compensating spray nozzle 321 connected to the water guide pipe 320 is fixed on the side of the reference plate 311. It can replenish the water film to the edge of the BC battery while the air curtain is formed. The water film pre-wets the edge of the battery, reduces the surface tension of the cleaning fluid, and prevents the cleaning fluid from climbing to the front due to capillary action. The air curtain further blocks the diffusion path of the cleaning fluid.

[0038] A flushing pipe 330 is fixedly connected to the lower outer surface of the upper support housing 300. A front and rear guide rail 331 is fixedly connected to the inner surface of the upper support housing 300. A left and right guide rail 332 is provided on the outer surface of the output end of the front and rear guide rail 331. An etching nozzle 333 is provided on the outer surface of the output end of the left and right guide rail 332.

[0039] The flushing pipe 330, combined with the front-rear guide rails 331 and the left-right guide rails 332, achieves precise positioning of the etching nozzle 333 in a two-dimensional plane. The front-rear guide rail 331 is responsible for adjusting the front-rear distance between the nozzle and the BC battery, while the left-right guide rails 332 realize scanning flushing along the edge of the battery. The combination of the two allows the etching nozzle 333 to cover the entire BSG area on the back of the BC battery, avoiding cleaning blind spots. The high-flow-rate water output of the flushing pipe 330 can quickly remove the waste liquid generated by the etching reaction, prevent the reaction products from depositing on the battery surface and forming secondary pollution, and improve the uniformity of cleaning.

[0040] A six-axis robotic arm 501 is fixedly connected to the outer surface of the output end of the precision cleaning mechanism 500, and an etching and rinsing nozzle 502 is fixedly connected to the outer surface of the output end of the six-axis robotic arm 501.

[0041] The precision cleaning mechanism 500 drives the etching and rinsing nozzle 502 through a six-axis robotic arm 501, breaking through the movement limitations of traditional fixed nozzles. The six-axis robotic arm 501 can achieve multi-degree-of-freedom movement of X / Y / Z three-axis translation and rotation around the axis, enabling the etching and rinsing nozzle 502 to accurately target micro-defects on the back of the BC battery for point-to-point and quantitative rinsing.

[0042] The flushing pump 600 includes a water pump 610 and a hydrofluoric acid water pump 620. The outer surface of the output end of the water pump 610 is fixedly connected to the water guide pipe 320 and the flushing pipe 330. The outer surfaces of the two independent output ends of the hydrofluoric acid water pump 620 are fixedly connected to the etching nozzle 333 and the etching flushing nozzle 502, respectively.

[0043] The flushing pump 600 adopts a dual-pump independent supply design with a water pump 610 and a hydrofluoric acid water pump 620, achieving pipeline isolation between pure water and hydrofluoric acid. The water pump 610 is dedicated to supplying pure water to the water guide pipe 320 and the flushing pipe outlet 330, ensuring no chemical reagent residue during the pre-rinse and final rinsing stages; the two independent output terminals of the hydrofluoric acid water pump 620 are respectively connected to the etching nozzle 333 and the etching flushing nozzle 502, facilitating independent control.

[0044] A water storage box 101 is fixedly connected to the inner surface of the middle of the working frame 100. The water storage box 101 is made of polytetrafluoroethylene (PTFE), and the hydrofluoric acid water pump 620 is also made of PTFE.

[0045] The water storage box 101 inside the working frame 100 is made of polytetrafluoroethylene (PTFE), whose resistance to hydrofluoric acid corrosion ensures long-term stability. At the same time, the surface inertness of PTFE reduces waste liquid residue and facilitates cleaning. The delivery pipeline of the hydrofluoric acid pump 620 is also made of PTFE, eliminating the risk of hydrofluoric acid leakage at the source and improving equipment safety.

[0046] The implementation principle of this application's embodiment of a precise wet cleaning machine for removing BSG from the back of BC batteries is as follows: The equipment uses the working frame 100 as the cleaning position, and the water storage box 101 provides storage and treatment space for the wastewater after cleaning. The rack 205 can be adjusted left and right by pulling it outward at the adjusting plate 206. Pressing down locks the rack 205 into a limiting position, and adjusting the length to fix the BC battery. When the BC battery is inserted horizontally into the clamping frame 200, the clamping block 202 is forced to squeeze the end of the rocker arm 203. Through the lever, the other side is lifted, squeezing the front panel of the BC battery to complete the fixation. The battery is then inserted into the clamping frame 200 from the side of the upper support shell 300. As the telescopic motor 402 descends, the clamping frame 200 tilts downwards on the corresponding side, causing the BC battery backplate to tilt towards the water storage box 101. The width of the air nozzle 310 is manually adjustable. Water is flushed to the water guide pipe 320 and the flushing pipe outlet 330 by the water pump 610. The housing of the air pump 312 is inserted into the adjusted position of the air nozzle 310, and air is blown in to provide a protective layer for the side of the BC battery. The water guide pipe 320 provides water film compensation to the corresponding compensating spray nozzle 321. The hydrofluoric acid water pump 620 flushes hydrofluoric acid to the etching nozzle 333. The etching nozzle 333 is adjusted left and right via the left and right guide rails 332, which in turn are adjusted forward and backward via the front and rear guide rails 331. This facilitates the etching and cleaning of the BC battery by the etching nozzle 333. The tilting mechanism allows for stable rinsing of the cleaning fluid by gravity, preventing corrosion from being difficult to detect after prolonged storage on the back of the BC battery. The winding mechanism 403 winds up the force-bearing wheel 204, facilitating the lifting of one side of the clamping frame 200. The winding mechanism 403 is then linearly moved by the transmission belt 401 to the desired position. The precision cleaning mechanism 500 flips the back of the BC battery, tilting it downwards. This allows the six-axis robotic arm 501 to easily adjust left and right, while the robotic arm 501 places the etching nozzle 502 in the appropriate position. Hydrofluoric acid water is then pumped into the etching nozzle 502 by the hydrofluoric acid pump 620. Through precise release, it provides accurate external force to the back of the BC battery, ensuring the accuracy of the cleaning. After rinsing with the cleaning agent, the battery falls back into the water storage box 101 under gravity, completing the collection process.
