[0001] This invention relates to the field of battery cell technology, and in particular to a wet cleaning device and method for battery cells. Background Technology

[0002] Solar cells, generally referring to photovoltaic (PV) cells, are thin photovoltaic semiconductor wafers that directly generate electricity using sunlight. They are the core component of PV power generation, converting light energy into electrical energy. The performance and quality of solar cells directly affect the output power and power generation efficiency of solar cell modules.

[0003] In some existing cleaning equipment, impurities on the surface of solar cells may be removed during wet cleaning, but due to their strong adhesion, the removal may not be complete. If impurities are present in the cleaning solution, they may also remain on the solar cells during cleaning, resulting in inadequate cleaning and a high probability of damage to the solar cells during subsequent processing. Summary of the Invention

[0004] In view of the problems of the aforementioned wet cleaning equipment for battery cells, this invention is proposed.

[0005] Therefore, the purpose of this invention is to provide a wet cleaning device and method for battery cells, which solves the problems of some cleaning devices removing impurities from the surface of battery cells during wet cleaning, but not completely removing them due to strong adhesion, and leaving residues on the battery cells if there are impurities in the cleaning solution, resulting in inadequate cleaning and a high rate of damage to the battery cells in subsequent processing.

[0010] As a preferred embodiment of the wet cleaning equipment and cleaning method for battery cells described in this invention, a cleaning screen is provided on the side of the filter barrel away from the filter box, and an inlet groove matching the filter barrel and the cleaning screen is opened on the inner side of the cleaning box, and the inlet groove extends to the position of the storage box.

[0011] In a preferred embodiment of the wet cleaning equipment and method for battery cells described in this invention, the moving unit includes a sprocket disposed on the outer side of a first reciprocating lead screw. A chain is disposed on the outer side of the sprocket. Rotating shafts are disposed on both the front and rear sides of the inner side of the chain. Multiple sets of worm gears are disposed on the outer side of the rotating shafts. A placement plate is disposed on the bottom surface of the cleaning box. A lifting plate is disposed on the side of the placement plate away from the cleaning box. Multiple supports are disposed on the bottom surface of the lifting plate.

[0014] A wet cleaning method for battery cells, comprising the following steps:

[0015] Step 1. Place the battery cells inside the battery rack, and transport the assembled battery rack to the mobile unit via the transport unit structure.

[0016] Step 2. The battery cells inside the battery rack are cleaned by reacting with different solutions stored in multiple cleaning boxes. During the cleaning process, they are rinsed through the drain plate in the cleaning unit structure, and the fallen objects are collected and processed through the filter component.

[0017] Step 3. The battery cells inside the battery rack are moved to different solutions for cleaning using a moving unit, and then moved to a cleaning box for drying.

[0018] The beneficial effects of this invention are:

[0019] 1. The solution is sprayed through a drain plate at the bottom, preventing debris from settling on the top surface of the cleaning plate after cleaning the battery cells. This keeps the inside of the cleaning box clean and reduces the risk of contamination of the solution itself, which could compromise the cleaning quality. The solution sprays out from the bottom of the upright battery cells, cleaning the debris and carrying it through the slag drain into the filter assembly. The filter assembly collects the debris, minimizing the risk of it contaminating the solution. After filtration, the solution is stored in a liquid storage box for later use. The liquid storage box can be disassembled for maintenance after a period of use, ensuring the cleanliness of the solution used on the drain plate and guaranteeing the quality of battery cell cleaning.

[0020] 2. When protecting the structure of the component, the cleaning box can be lifted upwards, causing the inner drain plate to move upwards. The drain plate then moves the first connecting pipe upwards. During the upward movement of the first connecting pipe, the telescopic rod retracts under the action of the spring, causing the sealing cover to fit against the second connecting pipe, thus closing the structure of the protective component. This prevents external impurities from entering the inner side of the protective component structure, ensuring its cleanliness. Furthermore, the protective component structure can be quickly disassembled and separated, facilitating the disassembly and maintenance of the cleaning box structure. This ensures the cleanliness of the structure storing the reaction solution, thereby improving the cleaning quality of the battery cells by this equipment.

[0021] 3. The filter box uses a short filter barrel to drive the cleaning screen to clean the inner wall of the inlet tank, preventing the adhesion of small impurities and thus reducing the amount of impurities stored in the storage box. When the drain pipe is lifted and the protection components are closed, the solution stored in the cleaning box will enter the cleaning tank through the connection between the drain plate and the first connecting pipe. The solution stored in the tank will then enter the storage box after the cleaning screen cleans the inlet tank. As the solution passes through the inlet tank, it will strongly rinse the inner wall of the cleaning screen, thereby separating impurities from the inner wall of the inlet tank and ensuring the cleanliness of the cleaning structure itself, thus improving the cleaning quality of the battery cells.

[0022] 4. By moving the lifting plate left and right, the battery rack placed in the groove on the surface of the placement plate is moved to the next groove. The lifting plate suddenly lifts the battery rack, causing the dissolved substances stored inside the battery cleaning box to separate abruptly, thus accelerating the separation from the surface deposits. In addition, the lifting plate moves the battery rack in an arc motion to the next groove on the placement plate, which also dries the attached solution to a certain extent, thereby keeping the surface of the battery cells clean.

Detailed Implementation

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0034] Referring to Figures 1-5, an embodiment of the present invention provides a wet cleaning device for battery cells, which includes: a cleaning box 1, a transport box 101 disposed on the top surface of the cleaning box 1, a cleaning unit 200 disposed on the inner side of the cleaning box 1, a moving unit 300 disposed on the inner bottom surface of the cleaning box 1, and the moving unit 300 being located on the front and rear sides of the cleaning unit 200, and a transport unit 400 disposed on the top surface of the transport box 101.

[0035] The cleaning unit 200 includes a motor 201 disposed on the inner side of the transport box 101. Multiple first reciprocating lead screws 202 are disposed at the output end of the motor 201. A pressure plate 203 is disposed on the outer side of the first reciprocating lead screws 202 via reciprocating threads. A fluid exchange chamber 204 matching the pressure plate 203 is opened on the inner side of the cleaning box 1. Multiple cleaning boxes 205 are disposed on the bottom surface of the cleaning box 1, and the cleaning boxes 205 are located above the fluid exchange chambers 204. A drain plate 208 is disposed on the bottom surface of the cleaning box 205, and a protective component 207 is disposed on the bottom surface of the drain plate 208. The fluid exchange chamber 204 and... A drain pipe 206 is provided between the protection components 207, and a one-way valve is provided between the drain pipe 206 and the liquid exchange chamber 204. A liquid storage box 211 is provided on the inner side of the cleaning box 1, and the liquid storage box 211 is located below the liquid exchange chamber 204. A suction pipe 210 is provided on the bottom surface of the liquid storage box 211, and the suction pipe 210 passes through the one-way valve to the inner side of the liquid exchange chamber 204. Multiple sets of filter components 209 are provided on the inner side of the cleaning box 205, and the filter components 209 are located on the left and right sides of the drain plate 208. A sludge discharge trough 212 is provided between the cleaning box 205 and the filter components 209.

[0036] Specifically, when using this device, the battery needs to be placed on the battery rack beforehand, and then the battery rack is placed in the transport unit 400 inside the transport box 101. The transport unit 400 pushes the battery rack to the right, and then the battery rack moves onto the moving unit 300 structure. The moving unit 300 then picks it up and places it into the cleaning box 205, which stores different solutions. This allows the battery cells to undergo wet cleaning through the cleaning box 205. When the battery cells are inside the cleaning box 205, the motor 201 starts, driving the first reciprocating screw 202 to rotate. The first reciprocating screw 202 drives the pressure plate 203 to rotate through its reciprocating threads. The pressure plate 203 moves back and forth inside the liquid exchange chamber 204, creating pressure. Through the connection of the one-way valve and the suction pipe 210, the solution is drawn from the storage box 211 and then discharged into the drain pipe 206 under the action of the one-way valve. After passing through the protection component 207, it enters the drain plate 208. The solution rinses the battery cells placed inside the cleaning box 205 above the drain plate 208, ensuring thorough contact with the cells for cleaning. The solution is also sprayed through the drain plate 208 at the bottom, preventing debris from settling on its surface and maintaining the cleanliness of the inside of the cleaning box 205. This reduces the risk of contamination of the solution itself, which could compromise the cleaning quality. After cleaning the upright battery cells from the bottom, the solution carries away debris through the slag drain 212 into the filter assembly 209, where it is collected. This reduces the risk of debris contaminating the solution inside the cleaning box 205. The filtered solution is then stored in the liquid storage box 211 for future use. After a period of use, the liquid storage box 211 can be disassembled for maintenance, ensuring the cleanliness of the solution used on the drain plate 208 and guaranteeing the quality of the battery cell cleaning.

[0037] Referring to FIG3, the protection component 207 includes multiple sets of first connecting pipes 2071 disposed on the bottom surface of the drainage plate 208. A sealing cover 2073 is disposed on the bottom surface of the first connecting pipe 2071. Multiple sets of telescopic rods 2074 are disposed on the top surface of the sealing cover 2073. A second connecting pipe 2072 is disposed between the top surfaces of the four telescopic rods 2074. A spring 2075 is disposed between the sealing cover 2073 and the second connecting pipe 2072, and the spring 2075 is slidably connected to the telescopic rods 2074. Multiple water inlet grooves 2076 are opened on the outer side of the first connecting pipe 2071.

[0038] Specifically, when using the structure of the protection component 207, the structure of the cleaning box 205 can be lifted upwards, causing the inner drain plate 208 of the cleaning box 205 to move upwards. The drain plate 208 then moves the first connecting pipe 2071 upwards. During the upward movement of the first connecting pipe 2071, the telescopic rod 2074 retracts under the action of the spring 2075, causing the sealing cover 2073 to fit against the second connecting pipe 2072, thus closing the structure of the protection component 207. This prevents external impurities from entering the inner side of the protection component 207, thereby ensuring the cleanliness of the protection component 207. Furthermore, the protection component 207 can be quickly disassembled and separated, facilitating the disassembly and maintenance of the cleaning box 205, thereby ensuring the cleanliness of the structure storing the reaction solution and improving the cleaning quality of the battery cells by this equipment.

[0039] Referring to FIG3, the filter assembly 209 includes a plurality of filter boxes 2091 disposed on the bottom surface of the cleaning box 205, and the filter boxes 2091 are located on the left and right sides of the drain plate 208, and a filter short barrel 2092 is disposed on the bottom surface of the filter box 2091.

[0040] Specifically, after the battery cells are cleaned, the debris that falls off floats up under the spraying action of the drainage plate 208. Then, under the continuous flow of solution from the bottom of the drainage plate 208, the debris enters the filter box 2091 through the slag discharge trough 212 and is filtered by the filter box 2091. The bottom of the filter box 2091 is equipped with a filter short barrel 2092 to keep the inside of the connection groove clean.

[0041] Referring to Figure 3, a cleaning screen 2093 is provided on the side of the filter short barrel 2092 away from the filter box 2091. An inlet groove 2094 matching the filter short barrel 2092 and the cleaning screen 2093 is opened on the inner side of the cleaning box 1, and the inlet groove 2094 extends to the position of the liquid storage box 211.

[0042] Specifically, impurities inside the solution are filtered through the filter box 2091 and the filter barrel 2092, and then enter the storage box 211 through the inlet tank 2094. When it is necessary to clean or replace the filter assembly 209, the filter box 2091 is lifted upwards. The filter box 2091 causes the entire structure of the filter assembly 209 to separate from the cleaning box 205. The filter box 2091, through the filter barrel 2092, drives the cleaning screen 2093 to clean the inner wall of the inlet tank 2094, preventing the adhesion of fine impurities, thereby reducing the amount of impurities stored inside the storage box 211, and also reducing the amount of impurities in the drain pipe 206. When the protection component 207 is closed, the solution stored inside the cleaning box 205 enters the cleaning tank 1 through the connection between the drain plate 208 and the first connecting pipe 2071. A slot matching the cleaning box 205 is opened inside the cleaning tank 1. The solution stored in the slot is then cleaned by the cleaning screen 2093 and enters the storage box 211 through the inlet slot 2094. When the solution passes through the inlet slot 2094, it will strongly rinse the inner wall of the cleaning screen 2093, thereby separating impurities from the inner wall of the inlet slot 2094, ensuring the cleanliness of the cleaning structure itself, and thus improving the cleaning quality of the battery cells.

[0043] Referring to Figure 4, the moving unit 300 includes a sprocket 311 disposed on the outer side of the first reciprocating screw 202. A chain 301 is disposed on the outer side of the sprocket 311. A rotating shaft 302 is disposed on both the front and rear sides of the inner side of the chain 301. Multiple sets of worm gears 303 are disposed on the outer side of the rotating shaft 302. A placement plate 310 is disposed on the bottom surface of the cleaning box 1. A lifting plate 309 is disposed on the side of the placement plate 310 away from the cleaning box 205. Multiple supports 308 are disposed on the bottom surface of the lifting plate 309. A second connecting rod 307 is disposed on the side of the support 308 away from the filter assembly 209. A turntable 306 is disposed on the outer side of the second connecting rod 307. A first connecting rod 305 is disposed on the inner side of the turntable 306. A worm gear 304 is disposed on the end of the cleaning box 205 away from the turntable 306, and the worm gear 304 meshes with the worm gear 303.

[0044] Specifically, when using this device, the motor 201 drives the sprocket 311 to rotate in the starting state. The sprocket 311 drives the two rotating shafts 302 to rotate via the chain 301. The rotating shafts 302 drive the worm gear 304 to rotate via the worm gear 303 on the surface. The liquid exchange chamber 204 drives the turntable 306 to rotate via the first connecting rod 305. During the rotation, the turntable 306 moves left and right due to the setting of the eccentric shaft and the rotational connection between the second connecting rod 307 and the turntable 306. By moving the lifting plate 309 left and right, the battery rack placed in the groove on the surface of the placement plate 310 is moved to the next groove. The sudden lifting of the battery rack by the lifting plate 309 causes the dissolved substances stored in the battery rain cleaning box 205 to separate abruptly, accelerating the separation speed from the surface deposits. In the process of the lifting plate 309 moving the battery rack in an arc motion to the next groove of the placement plate 310, the attached solution is dried to a certain extent, thereby keeping the surface of the battery cells clean.

[0045] Referring to Figures 4-5, the transport unit 400 includes a second reciprocating screw 401 disposed at the end of the rotating shaft 302 away from the worm gear 303. A third connecting rod 405 is disposed at the end of the second reciprocating screw 401 away from the rotating shaft 302. A first bevel gear 406 is disposed at the end of the third connecting rod 405 away from the second reciprocating screw 401. A rotating shaft 407 is disposed on the inner side of the transport box 101. A second bevel gear 408 is disposed at the lower end of the rotating shaft 407, and the second bevel gear 408 meshes with the third connecting rod 405. A top end of the rotating shaft 407 is provided with... There is a fourth bevel gear 415. Multiple conveyor rollers 409 are provided on the inner walls of the front and rear sides of the transport box 101. A third bevel gear 410 is provided on the end of the left conveyor roller 409 away from the motor 201, and the third bevel gear 410 meshes with the fourth bevel gear 415. A conveyor belt 411 is provided between the outer walls of the left and right conveyor rollers 409. Multiple magnets 412 are provided on the side of the conveyor belt 411 away from the conveyor rollers 409. An auxiliary plate 413 is provided between the outer walls of the left and right conveyor rollers 409, and the auxiliary plate 413 is slidably connected to the conveyor belt 411.

[0046] Specifically, when using this device, the pre-assembled battery rack needs to be placed on the outer side of the conveyor belt 411 between two magnets 412. By setting the spacing of the magnets 412 on the surface of the conveyor belt 411, it can be adjusted according to the vertical drop of the battery cells. Then, the rotating shaft 302 drives the second reciprocating screw 401 to rotate, and the second reciprocating screw 401 drives the third connecting rod 405 to rotate. The third connecting rod 405 drives the rotating shaft 407 to rotate through the meshing of the first bevel gear 406 and the second bevel gear 408. The rotating shaft 407 drives the conveyor roller 409 to rotate through the meshing of the third bevel gear 410 and the fourth bevel gear 415. The two conveyor rollers 409 drive the sprocket 311 to rotate, thereby transporting the battery rack placed on the surface of the conveyor belt 411 from left to right. The transmission effect of multiple motors demonstrates the multiple utilizations of the power structure.

[0047] Referring to Figures 4-5, a slider 402 is provided on the outer side of the second reciprocating screw 401 via a reciprocating thread, a connecting plate 403 is provided on the outer side of the connecting plate 403, a gripper 404 is provided on the top of the connecting plate 403 via a rubber belt, and a stop plate 414 is provided on the side of the gripper 404 near the motor 201.

[0048] Specifically, when the conveyor belt 411 transports the battery rack to the surface of the stop plate 414, the second reciprocating screw 401 drives the slider 402 to move to the right. The slider 402 drives the gripper 404 to push the battery rack through the connecting plate 403, pushing the battery rack into the groove opened in the lifting plate 309, and at the same time, the first step of solution reaction takes place. The connecting plate 403 is connected to the gripper 404 by a rubber belt, and the contact surface between the gripper 404 and the connecting plate 403 is that the right side of the gripper 404 protrudes and the left side of the connecting plate 403 protrudes. When the gripper 404 moves to the right, it fits against the connecting plate 403 due to the gravity of the battery rack. When the gripper 404 moves to the left, the gripper 404 flips under the action of the rubber belt due to the obstruction of the battery rack, temporarily reducing the contact surface with the connecting plate 403, thereby facilitating the movement of the battery rack.

[0049] The wet cleaning method for battery cells includes the following steps:

[0050] S1. Place the battery cells inside the battery rack, and transport the assembled battery rack to the moving unit 300 structure in the transport unit 400 structure.

[0051] S2. The battery cells inside the battery rack are cleaned by reacting with different solutions stored in multiple cleaning boxes 205. During the cleaning process, they are rinsed by the drain plate 208 in the structure of the cleaning unit 200. During the cleaning process, the dropped objects are collected and processed by the filter assembly 209.

[0052] S3. The battery cells inside the battery rack are moved to different solutions for cleaning by the moving unit 300, and then moved to the cleaning box 1 for drying.

[0053] Working principle: When using this device, the battery needs to be placed on the battery rack beforehand. Then, the battery rack is placed in the transport unit 400 inside the transport box 101. Under the pushing action of the transport unit 400, the battery rack moves to the right and then moves to the moving unit 300 structure. The moving unit 300 grabs and places the battery into the cleaning box 205, which stores different solutions. This allows the battery to undergo wet cleaning through the cleaning box 205. When the battery is inside the cleaning box 205, the motor 201 starts and drives the first reciprocating screw 202 to rotate. The first reciprocating screw 202 drives the pressure plate 203 to rotate through the reciprocating threads on its surface. The pressure plate 203 moves back and forth inside the liquid exchange chamber 204 to create pressure. This pressure is generated through the one-way valve connected to the suction pipe 210. The solution is drawn from the storage box 211 and discharged into the drain pipe 206 under the action of the one-way valve. After passing through the protection component 207, it enters the drain plate 208 to rinse the battery cells placed in the cleaning box 205 above the drain plate 208, so that the solution can fully contact the battery cells for cleaning. The solution is also sprayed out through the drain plate 208 at the bottom, so that the debris after cleaning the battery cells will not settle on the top surface of the drain plate 208, thereby keeping the inside of the cleaning box 205 clean and reducing the possibility of poor battery cell cleaning quality due to solution contamination. After cleaning the upright battery cells from the bottom through the drain plate 208, the solution carries the cleaned debris through the slag discharge trough 212 into the filter component 209 for collection.
