Description

Technical Field

[0001] This invention relates to the field of battery cleaning technology, and more particularly to the TOPCon battery pure water cleaning device. Background Technology

[0002] As a type of high-efficiency solar cell, TOPCon cells require multiple cleaning processes during production, including pre-cleaning, alkaline texturing, acid washing, and final pure water cleaning. Among these, the pure water cleaning stage is crucial, as it is necessary to remove residual chemicals from the previous processes (such as alkaline texturing and acid washing) and to quickly dry the cell surface after cleaning to prevent water stains from affecting subsequent storage or processing.

[0003] However, existing cleaning devices mostly use fixed spray structures, with cleaning and drying performed in separate steps, resulting in low efficiency. The wastewater collection system is usually open, which cannot effectively prevent splashing, and it lacks height adjustment function, which can easily cause interference when the battery is flipped. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a TOPCon battery pure water cleaning device, which solves the technical problem that the cleaning and drying processes of existing cleaning devices need to be carried out in separate steps, resulting in low efficiency. It has the advantages of being able to complete cleaning and drying in one integrated manner, and achieving stable clamping and convenient flipping.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a TOPCon battery pure water cleaning device, including a mounting bracket, on which a movable cleaning mechanism for cleaning the battery body is provided. Battery clamping mechanisms for flipping the battery are symmetrically arranged on both sides of the mounting bracket. During cleaning, firstly, the battery clamping mechanisms clamp and fix the TOPCon battery. Subsequently, the movable cleaning mechanism cleans and dries the battery surface. During the cleaning process, a cleaning auxiliary mechanism collects the wastewater generated during cleaning. The movable cleaning mechanism includes horizontal slide rails symmetrically arranged on both sides of the mounting bracket. A movable platform is movably mounted on the horizontal slide rails. A drive component is provided inside the horizontal slide rails. A high-pressure water pump is detachably mounted on the movable platform. The output end of the high-pressure water pump is connected to a cleaning nozzle. The cleaning nozzle is fixedly connected to the movable platform. A blower assembly is fixedly mounted on the movable platform. The output end of the blower assembly is connected to a first air duct and a second air duct. The first and second air ducts are located on both sides of the cleaning nozzle, respectively. During the horizontal movement of the movable platform, the cleaning nozzle sprays and rinses the surface of the battery body.

[0006] Preferably, the drive assembly includes a threaded rod, which is movably mounted inside the horizontal slide rail. The moving platform has a threaded through groove that mates with the threaded rod. When the threaded rod rotates around its own axis, it causes the moving platform to move horizontally along the horizontal slide rail.

[0007] Preferably, the first air duct and the second air duct can discharge hot air or cold air separately, and the two can be controlled independently, and both can blow out hot air or cold air under the action of the blowing assembly.

[0008] Preferably, the battery clamping mechanism includes mounting cylinders symmetrically arranged on both sides of the mounting bracket, clamping components are movably mounted on the mounting cylinders, a push spring is fixedly installed inside the mounting cylinders, and buckle components are symmetrically arranged on the outer side of the mounting cylinders. The mounting cylinders are rotatably connected to the mounting bracket, and when the mounting cylinders rotate, they will drive the clamping components to rotate synchronously, thereby completing the battery flipping.

[0009] Preferably, the clamping assembly includes a cylindrical part and a rubber block part. The cylindrical part is slidably connected to the mounting cylinder. A limiting protrusion is fixedly installed on the outer side of the cylindrical part. The presence of the limiting protrusion ensures that there is no relative rotation between the clamping assembly and the mounting cylinder, and the clamping assembly can only slide outward or inward.

[0010] Preferably, the buckle assembly is movably installed on the outside of the mounting cylinder, the mounting cylinder is provided with a limiting spring inside, and the mounting bracket is provided with a slot S that matches the buckle assembly inside. Initially, the buckle assembly will engage with the slot under the action of the limiting spring. When the mounting cylinder is twisted forcefully, the buckle assembly will disengage from the slot.

[0011] Preferably, the mobile cleaning mechanism is provided with a cleaning auxiliary mechanism for collecting cleaning wastewater below. The cleaning auxiliary mechanism includes an inclined water tank fixedly installed inside the mounting bracket, a drain pipe fixedly installed on the outside of the mounting bracket, the drain pipe being connected to the inclined water tank, and a water receiving tray at the lower end of the mounting bracket. During the spray cleaning process, the mounting bracket can play a certain role in shielding and preventing water droplets from splashing. After the water droplets splash onto the mounting bracket, they will fall into the interior of the inclined water tank.

[0012] Preferably, the mounting bracket has a vertical sliding groove, and the water receiving tray is slidably connected to the vertical sliding groove. The height of the water receiving tray can be freely adjusted, which will not obstruct the view when the battery is flipped over, and can also shorten the water receiving height to prevent splashing during the water receiving process.

[0013] By employing the above technical solution, the present invention provides a TOPCon battery pure water cleaning device, which has at least the following beneficial effects: 1. This invention features a mobile cleaning mechanism that uses a mobile platform to drive a high-pressure water pump and cleaning nozzles to move back and forth. Combined with a first and second air duct connected in parallel, the first air duct blows normal air to remove residual liquids during forward movement, while the second air duct blows hot air to dry the surface. The function is switched during reverse movement, achieving efficient synergy between spray cleaning and immediate drying. This significantly improves the cleaning efficiency and drying effect of the battery surface and avoids water stains.

[0014] 2. By setting up a mobile cleaning mechanism, the rotation of the threaded rod in the horizontal slide rail will drive the mobile platform to move precisely horizontally. Combined with the independently controllable first and second air ducts, the cleaning process can dynamically adjust the air direction and temperature according to the needs. This can not only adapt to the process requirements of different cleaning stages, but also ensure the consistency and controllability of battery surface treatment, reducing energy consumption and operational complexity.

[0015] 3. By setting up a battery clamping mechanism, the clamping component is slidably connected to the mounting cylinder through the limiting protrusion of the column part, which can ensure that no relative rotation occurs during the clamping process. At the same time, with the elastic pressure of the push spring, the battery body is firmly clamped, which can effectively prevent displacement or shaking during the cleaning process and improve the stability and safety of the cleaning operation.

[0016] 4. By setting up a battery clamping mechanism, the mounting cylinder adopts a design that combines a buckle assembly and a limiting spring. In the initial state, the buckle automatically snaps into the slot and fixes itself in place. When flipping, simply rotating the mounting cylinder will disengage the buckle and re-engage it. This allows for quick flipping and precise positioning of the battery body, simplifying the operation process and significantly improving cleaning efficiency.

[0017] 5. By setting up a cleaning auxiliary mechanism, the present invention can effectively block and guide the water droplets splashed by the spray by cooperating with the inclined water tank and the drainage pipe, preventing water from accumulating on the battery body. At the same time, the height-adjustable water receiving tray can flexibly adapt to the needs of different cleaning stages, which can not only avoid interference when the battery is turned over, but also shorten the water receiving distance to reduce secondary splashing, significantly reducing the risk of environmental pollution and keeping the working environment clean.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Existing cleaning devices mostly employ fixed spray structures, with cleaning and drying performed in separate steps, resulting in low efficiency. To address this technical deficiency in existing technologies, such as... Figure 1 , Figure 2 as well as Figure 3 As shown, this embodiment features a TOPCon battery pure water cleaning device, achieving efficient synergy between spray cleaning and immediate drying, significantly improving the cleaning efficiency and drying effect of the battery surface. The device includes a mounting bracket 1, with the battery body 2 placed inside the mounting bracket 1. The mounting bracket 1 is equipped with a movable cleaning mechanism 3 for cleaning the battery body 2. Battery clamping mechanisms 4 for flipping the battery are symmetrically arranged on both sides of the mounting bracket 1. During the cleaning operation, firstly, the battery clamping mechanism 4 clamps and fixes the TOPCon battery. Subsequently, the movable cleaning mechanism 3 cleans and dries the battery surface. During the cleaning process, the cleaning auxiliary mechanism 5 collects the wastewater generated during cleaning.

[0022] Specifically, the mobile cleaning mechanism 3 includes horizontal slide rails 301 symmetrically arranged on both sides of the mounting bracket 1. A mobile platform 302 is movably mounted on the horizontal slide rails 301. A drive assembly 303 is disposed inside the horizontal slide rails 301. A high-pressure water pump 304 is detachably mounted on the mobile platform 302. The output end of the high-pressure water pump 304 is connected to a cleaning nozzle 305. The cleaning nozzle 305 is fixedly connected to the mobile platform 302. A blower assembly 306 is fixedly mounted on the mobile platform 302. The output end of the blower assembly 306 is connected to a first air duct 307 and a second air duct 308. The first air duct 307 and... The second air duct 308 is set in parallel and controlled independently. Both can blow out hot or cold air under the action of the blowing assembly 306. The first air duct 307 and the second air duct 308 are located on both sides of the cleaning nozzle 305. During the horizontal movement of the moving platform 302, the cleaning nozzle 305 will spray and rinse the surface of the battery body 2. The drive assembly 303 includes a threaded rod that is movably installed inside the horizontal slide rail 301. The moving platform 302 is provided with a threaded through groove 309 that cooperates with the threaded rod. When the threaded rod rotates around its own axis, it will cause the moving platform 302 to move horizontally along the horizontal slide rail 301.

[0023] As can be seen from the above, during the pure water cleaning operation, the mobile platform 302 will first move back and forth along the horizontal slide rail 301 under the action of the drive component 303. During the movement, the high-pressure water pump 304 will spray high-pressure water through the cleaning nozzle 305 to spray and clean the surface of the battery body 2.

[0024] When moving forward, the blower assembly 306 will discharge normal air through the first air duct 307 to remove existing liquids (chemicals left over from pre-cleaning, alkaline texturing, and acid washing processes) on the battery body 2. At the same time, the blower assembly 306 will discharge hot air through the second air duct 308 to dry the cleaned battery surface and prevent water stains.

[0025] When moving in the reverse direction, the blower assembly 306 will discharge normal air through the second air duct 308 and hot air through the first air duct 307, thereby efficiently cleaning the battery body 2.

[0026] This embodiment features a mobile cleaning mechanism 3. A mobile platform 302 drives a high-pressure water pump 304 and a cleaning nozzle 305 to reciprocate. Combined with a parallel first air duct 307 and a second air duct 308, the first air duct 307 blows normal air to remove residual liquid during forward movement, while the second air duct 308 blows hot air to dry the surface. The reverse movement switches functions, achieving efficient synergy between spray cleaning and immediate drying. This significantly improves the cleaning efficiency and drying effect of the battery surface, preventing water stains. Furthermore, the mobile cleaning mechanism 3 allows the threaded rod within the horizontal slide rail 301 to rotate, precisely moving the mobile platform 302 horizontally. Combined with independently controllable first and second air ducts 307 and 308, the cleaning process can dynamically adjust the airflow direction and temperature as needed. This adapts to the process requirements of different cleaning stages, ensuring the consistency and controllability of battery surface treatment, while reducing energy consumption and operational complexity.

[0027] Example 2 To prevent displacement or shaking of the battery body 2 during cleaning and to improve the stability and safety of the cleaning operation, based on Example 1, as follows: Figure 1 , Figure 4 , Figure 5 as well as Figure 7 As shown, this embodiment includes a battery clamping mechanism 4. Specifically, the battery clamping mechanism 4 includes mounting cylinders 401 symmetrically arranged on both sides of the mounting bracket 1. A clamping assembly 402 is movably mounted on the mounting cylinders 401. A push spring 403 is fixedly installed inside the mounting cylinders 401. The clamping assembly 402 includes a cylindrical part and a rubber block part. The cylindrical part is slidably connected to the mounting cylinders 401. A limiting protrusion 404 is fixedly installed on the outer side of the cylindrical part. The presence of the limiting protrusion 404 ensures that there is no relative rotation between the clamping assembly 402 and the mounting cylinders 401. The clamping assembly 402 can only move towards the mounting cylinders 1. The mounting cylinder 401 is symmetrically provided with a buckle assembly 405 on its outer side, which can slide outward or inward. The mounting cylinder 401 is rotatably connected to the mounting bracket 1. When the mounting cylinder 401 rotates, it will drive the clamping assembly 402 to rotate synchronously, thereby completing the battery flipping. The buckle assembly 405 is movably installed on the outer side of the mounting cylinder 401. The mounting cylinder 401 is provided with a limit spring inside. The mounting bracket 1 is provided with a slot S that matches the buckle assembly 405 inside. Initially, the buckle assembly 405 will engage with the slot under the action of the limit spring. When the mounting cylinder 401 is twisted forcefully, the buckle assembly 405 will disengage from the slot.

[0028] As can be seen from the above, when the staff places the battery body 2 between the two clamping components 402, the clamping components 402 will clamp and fix the battery body 2 under the action of the push spring 403, thereby ensuring stability during the cleaning process.

[0029] When the battery body 2 needs to be flipped over, the operator will turn the mounting cylinder 401 clockwise. At this time, the buckle assembly 405 will move out of the slot. After the mounting cylinder 401 is rotated 180 degrees, the buckle assembly 405 will extend back into the slot, thereby fixing the position of the flipped battery body 2.

[0030] This embodiment features a battery clamping mechanism 4. The clamping component 402 is slidably connected to the mounting cylinder 401 via a limiting protrusion 404 on the cylindrical part, ensuring no relative rotation occurs during clamping. Simultaneously, the elastic pressure of the push spring 403 firmly clamps the battery body 2, effectively preventing displacement or shaking during cleaning and improving the stability and safety of the cleaning operation. Furthermore, this embodiment utilizes a battery clamping mechanism 4 with a mounting cylinder 401 employing a buckle component 405 and a limiting spring. In the initial state, the buckle automatically engages in the slot and is fixed in place. During flipping, simply rotating the mounting cylinder 401 disengages the buckle and re-engages it, enabling rapid flipping and precise positioning of the battery body 2, simplifying the operation process and significantly improving cleaning efficiency.

[0031] Example 3 To minimize the risk of environmental pollution and maintain a clean working environment, based on the above embodiments, such as Figure 1 , Figure 2 as well as Figure 6 As shown, this embodiment includes a cleaning auxiliary mechanism 5. Specifically, the cleaning auxiliary mechanism 5 for collecting cleaning wastewater is located below the mobile cleaning mechanism 3. The cleaning auxiliary mechanism 5 includes an inclined water tank 501 fixedly installed inside the mounting bracket 1, and a drain pipe 502 fixedly installed on the outside of the mounting bracket 1. The drain pipe 502 is connected to the inclined water tank 501. A water receiving tray 503 is provided at the lower end of the mounting bracket 1. During the spray cleaning process, the mounting bracket 1 can play a certain role in shielding and preventing water droplets from splashing. After the water droplets splash onto the mounting bracket 1, they will fall into the interior of the inclined water tank 501. A vertical sliding groove 504 is provided on the mounting bracket 1. The water receiving tray 503 is slidably connected to the vertical sliding groove 504. The height of the water receiving tray 503 can be freely adjusted so that it will not obstruct the view when the battery is flipped over, and it can also shorten the water receiving height to prevent splashing during the water receiving process.

[0032] As can be seen from the above, during the spray cleaning process, the mounting bracket 1 will shield the spray area, which can prevent sewage from splashing to a certain extent. The water splashed on the inner wall of the mounting bracket 1 will flow into the inclined water tank 501 and be discharged outward through the drain pipe 502. At the same time, the water receiving tray 503 will collect the sewage that falls during the cleaning process, which can greatly reduce the impact on the surrounding environment.

[0033] Moreover, during the cleaning process, staff can flexibly adjust the height of the water receiving tray 503, which will not obstruct the view when the battery is flipped over, and can also shorten the water receiving height to prevent splashing during the water receiving process.

[0034] This embodiment, by setting up a cleaning auxiliary mechanism 5, utilizes the cooperation between the inclined water tank 501 and the drainage pipe 502 to effectively block and guide the water droplets splashed by the spray, preventing water from accumulating on the battery body 2. At the same time, the height-adjustable water receiving tray 503 can flexibly adapt to the needs of different cleaning stages, which can not only avoid interference when the battery is turned over, but also shorten the water receiving distance to reduce secondary splashing, significantly reducing the risk of environmental pollution and keeping the working environment clean.

[0035] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
